The Preliminary Selection Process

Author's Note

Oh, and when I say myriad of other kinks, I mean a myriad.
Though, hopefully I can avoid becoming ridiculous with this debauchery.
Oh, and fair warning, it jumps right into it.

The Preliminary Selection Process

Twilight Sparkle knew all too well of the gender disparity plaguing Equestria, and like many mares, she herself was affected by the lack of options. For every stallion born, there were eight mares, and few ponies were open to the idea of polyamory, with even fewer being capable of pulling such a relationship off. This gap started off small, and remained rather steady up until sometime around the banishment of Nightmare Moon; one would think with the return of Princess Luna this issue would right itself, but for reasons unknown, the birth statistics remained the same. The birth rate of colts to fillies was still sobering, with no sign of improvement in sight.

Princess Celestia, in her wisdom, tasked the Canterlot Mages’ Society with finding a solution to this disparity. A spell was developed, one that rendered sperm cells carrying the X-chromosome immobile, for use in repopulating the kingdom; though with there already being so few stallions in small cities and towns, the issues of possible inbreeding over several generations kept it from seeing large-scale distribution. No, what Equestria needed was a way to generate new stallions without using the genetic stock already present; for this, Twilight Sparkle performed her own research into the matter. Transformation and, ahem, augmentation spells were often used by same sex couples, but sperm produced magically were entirely blank, genetically speaking.

So, if Twilight was going to make any difference, she needed to find a way to produce healthy sperm, without using a stallion or creating them directly through magic. In order to create what she needed, she had to first study the anatomy and inner workings of the male reproductive system; with a mixture of book-based research and experiments in manual stimulation of both natural penises and their facsimiles, she had a very clear picture of the look, feel, and function of the male primary sexual characteristics. Though, as necessary as all the bodily details were, the chemical makeup of seminal fluid, as well as the motion sperm cells utilized to meet the ovum, were just as important. To meet this end, Twilight hand-collected several samples from a local drinking establishment, as well as one or two from stallions who did not drink.

Texture, viscosity, sperm count, and taste were taken into account, enough so that Twilight felt reasonably sure she could create the necessary chemicals for the creation of seminal fluid. While most experiments regarding the body usually had sample pools of hundreds, she had to make do with thirty stallions, though in a town of only a few thousand, this accounted for a fair portion of the male population. Even Carrot Cake, the owner of Sugarcube Corner and father of a rambunctious pair of twins, was given permission by his wife to donate to the cause; Twilight still had no idea why Mrs. Cake insisted on using a penile facsimile to massage his prostate while she herself manually stimulated him. Given they had a colt, it wasn’t really her place to question their methods.

Though her sample size as relatively small, Twilight felt she had gathered enough data to begin preliminary trials. Her first attempts had been, in her opinion, riddled with laughable errors. filled with laughable errors; while many ponies would think of such attempts as failures, mistakes, the purple alicorn felt they were opportunities to learn, and every bit as important as success. Her spell, more of a quilt of dozens of other incantations woven together, have her the full setup one would find on a typical stallion, albeit temporarily. She still maintained her femininity, though it was obscured from the front by a pair of testicles; her first attempt had them so lopsided one was the size of a decent grapefruit and the other could have been mistaken for a robin’s egg. Now, they were a firm midline for her observations: a decent handful, but entirely palmable.

Similarly, her new stallionhood was originally titanic, massive enough that it diverted enough blood to dizzy her, even when sheathed. Its length and girth were now the mathematical averages of the stallions who had graciously donated their semen for study. Now, much like how it had been many times since Twilight create the organ, it tented the fabric of her sundress, which she only wore to keep her testes cool. Beside, most of her regular bottoms hadn’t been made for somepony with extra bits in the front. Having sported her tool for the better part of two weeks, with some magical stimulus to speed up the process, she harvested her first batch of true, swimming sperm cells shortly after waking up. The use of magic was necessary for the moment, as the entire process took somewhere in the area of three months; the entire process was sadly within the gap of equine understanding.

Thankfully, even under her most powerful microscope, the new gametes seemed perfectly like those found in most stallions; Twilight recorded the amount, sperm count, color, viscosity, and temperature before disposing of it in the method to which she’d grown accustomed. She had grown accustomed to the taste, and smiled as she raised the cylinder's brim to her lips; her product was sweet with a tart kick, a bit like strawberries mixed with lemons, and she groaned as the thick liquid left a warm trail down her throat that permeated her belly. She blushed and adjusted her sundress as the warmth radiated downwards and settled in her nethers; she had to keep quiet as she felt wetness spread from her duel sexes, a serious consequence of her now seemingly-bottomless arousal and overly-hormonal state.

She squirmed as her stallionhood rubbed against the pre-soaked cloth of her sundress, and opted to strip; in her mind, she was in the sanctity of her own laboratory, so being nude was no big deal. The cool, damp air of the basement kiss her skin in all the right places, and despite her earlier release, Twilight couldn’t help but trail a hand down her body, ignoring her rigid shaft in favor of her moist lips. Reclining in a chair, her fingers danced over her sex, until she slipped one in to rub at her clit. She curled up and spread her legs to better access herself, and plunged a finger into her tunnel. Tenderly, almost scared to be too rough, she wrapped a hand around her shaft and gave it a gently stroke.

Her hand was too dry to be enjoyable, so her lust-addled mind came up with a devious plan; she rubbed her entire hand against her marehood to coat in her liberally flowing juices, and used the now-wet appendage to stroke herself. The difference was like night and day, as she usually used her magic to stimulate her new organ; her warm, wet grip was nearly intoxicating as she slowly pumped at her sensitive shaft. She bit her lip to keep quiet as the still-alien sensations sent electricity up her spine. She groaned and sped up, arching her back against her hand as her horn sparked in sympathetic glee.

The strangest sensation spread through her lower body as her female sex mirrored the pleasure of its male counterpart. In her mind’s eye, Twilight saw a stallion hammering away at her pussy while a mare busied herself riding on her cock. She heard the brutish male grunt and hilt inside her, as he spilled his seed in her farthest depths; the mare shrieked and slammed down on her shaft, grinding through her own orgasm. Warm, wet splashes against her face woke Twilight from her stupor as her stallionhood twitched in her hand, sputtering out the last few drops of cum after shooting most of it over her.

“Um, Twilight,” Spike began, alerting the purple alicorn to his presence. Like always, he was rather supportive of her experiments, even if he made an effort to avoid assisting her in recording her results; Twilight figured it had something to do with the teenaged dragon being uncomfortable around another penis rather than being unwilling to help. “I, uh, talked to the paper about running the ad for a lab assistant, with you requirements.”

“Did you remember to put up the fliers?” she asked, catching her breath. Having male genitalia for the past couple of weeks, and dealing with the near constant arousal the added hormones forced her to experience, she realized her cum-covered state either disgusted her assistant, or provoked a few unwanted thoughts in him. A niggling voice in the back of her mind said teasing the teenage drake like this was perfectly okay, and overlayed his image with that of the stallion from her fantasy; the thought of her assistant taking her from behind aroused her more than Twilight wanted to admit, though her body thankfully remained calm.

“Uh huh, same level of detail and everything,” he answered, making a very serious effort to look only in her eyes. She knew taking enjoyment seeing him so flustered was probably wrong on some level, but a larger part relished in the idea; after all, Spike had certainly filled out since they moved to Ponyville, and could give a number of stallions a run for their money in the looks department.

“Thanks, Spike,” Twilight said, using her magic to collect to the cum from her face before tossing it back like her favorite drink. That same warmth blossomed again, but she maintained control of her urges and resisted that voice telling her to throw herself onto the table and beg her assistant to take her. “We’re going to accomplish a lot, I can tell.”

“Really think you can fix this whole mess?” Spike asked, handing her a fresh change of clothes. They were for her to wear during the interview process, so her new equipment didn't stick out like it would in a dress. The pants were new, purchased that morning while he was in town, and had the extra room to accommodate Twilight’s extra bits.

“We’ll do our very best,” she answered, smiling. Spike, obviously, wasn’t directly affected by the lack of colts being born, but with his long life, he would not want to see the race that raised him die out while he still drew breath. In a way, the alicorn realized her favorite assistant was a contingency plan, somepony to carry on if she died without completing her mission.

_-_-_-_The Next Day_-_-_-_

The Ponyville Daily ran a unique classified that morning, asking for a pony between the ages of twenty and forty to act as an assistant for Princess Twilight Sparkle. The age requirement was explained by a certain degree of physical activity that may have been too much for anypony too young or too old. This advertisement was mirrored by the countless fliers tacked and stapled to the various notice boards, signposts, and one or two windows. In every case, the words were clear, the language was informal, and the entire prospect was welcoming.

WANTED: Laboratory assistant.

Must be physically well and between the the ages of twenty and forty.

Must be able to take notes using scientific language and citation (willing to educate if need be)

Must be trustworthy, and able to keep sensitive information to oneself.

Inquire at Golden Oaks Library.

The stallions who answered were treated no differently than any other applicant, but all were told they were not the sort of help Twilight was looking for. Most ponies who answered the posting were looking for work during the summer, when most businesses either cut employee hours or simply shut down when the weather warmed up. Many of the mares who came in were either too young, married, currently in a committed relationship, engaged in behavior that could jeopardize the experiment, or were too old, and ran the risk of bearing foals who suffered from congenital maladies or other birth defects. As nice as the mares were, if they were outside the perfect range, and despite having very good chances of having children who were perfectly healthy, even slightly worse odds were thrown out.

After the rigorous selection, drug testing, paperwork, bloodwork, and a few other tests waved off as being necessary to see if the applicant was allergic to certain chemicals and materials, only two applicants viable. One was the resident mailmare, Derpy Hooves, aged thirty-two, who was already a mother with two daughters. Her reason for application was a hopefully temporary layoff while the postal unions were on strike, but there was no end in sight. She was single, passed all tests with flying colors, and demonstrated a level of clinical skill that was entirely unexpected from her. She was a strong choice for selection, and by her own admission, was willing to do whatever was necessary to feed her family.

The other hopeful was one Miss Cheerilee, local schoolteacher, aged thirty. Like Derpy, she passed everything swimmingly, but was not a mother herself; in fact, Twilight couldn't recall a single time she’d seen her with a stallion, or another mare for that matter, in a romantic setting, save for the incident with the love poison. Physically speaking, she was fit enough for the work that would be asked of her, but with her job guaranteed to begin again in autumn, information leaks may be an issue. She was, however, trustworthy enough to know of the other dubious experiments Twilight carried out, and even helped burn her vampire plants to death when asked.

This was a choice between two amazing possibilities, for different reasons; either the mailmare or the schoolteacher would be brought in on the secret. Were Twilight feeling risky, she could attempt to use them both, for two samples instead of the one she anticipated. Perhaps, if she took on both, she could try for an increase in research grants from the princesses, who were doubtlessly working on their own solutions.

“Spike, take a letter,” she began, smiling at her plan.

The Unique Proposal

Princess Celestia looked at the letter in confusion. Twilight Sparkle, her faithful student, had apparently taken it upon herself to solve the riddle of Equestria’s gender disparity through magical means. She had two possible volunteers, healthy mares still in their prime, and full intentions of paying, but had yet to actually inform them of everything they needed to do. Celestia knew all too well the necessity of secrecy, especially in regards to issues involving life, magic, and science, but with what these mares would be called to do, it was nearly deplorable to deny them the right to informed consent. Still, as terrible as Celestia found the idea, it may have been necessary.

“Young Twilight has given herself a penis?” Luna asked, though her tone suggested it was more of a statement than anything. Like her older sister, the entire notion struck her as incredibly odd, but well within the range of behavior she attributed to the young alicorn. The unusual methods were almost to be expected, given the extreme nature of the issue at hand, but the princess of the night was more fascinated by the leaps and bounds magic had made in her absence, if it could give a mare fully-functional phallus, along with the accompanying gonads. “I wonder why we were not told of this sooner,” she said, reading over her sister’s shoulder.

“Because, until now, it’s been impossible,” Celestia replied. “Though, I’m not sure that this is worth exploring.” She looked at her younger sister, a worried look plastered over her face. “If we can give mares this power, what becomes of the stallions we have? Will they no longer be needed?" she pondered aloud, worried that she would be exchanging a gender gap for an artificial, single-sex race. Twilight’s letter admitted her belief that this was merely a temporary solution, but there was always a chance that a larger population of stallions would fail to maintain their number once more.

“You say that like we’re on some sort of slippery slope, Tia,” Luna said, looking both amused and concerned. She knew there was a small chance that a number of ponies may think of stallions as redundant once a perfected form of Twilight’s proposed spell was made widely available, but she also knew some ponies would think that no matter what came of this experiment. “What young Twilight proposes is a chance, however slim, of finding a short-term solution so that we may then find a more suitable one for the long run.”

Princess Celestia gave her sister the letter, and pondered her options. As wonderfully careful as Twilight was, there was always the chance she would continue this avenue of research regardless of censure; it was better for everypony to have her approved to work, but under close and careful watch for any leaks, or possible misuse of resources. Twilight had two possible volunteers, and two possible subjects to pay if they consented, and while it was no big loss, it presented a unique dilemma. These two mares, both upstanding members of Ponyville society by the information provided, were essentially being paid for their services as mothers for Twilight’s possible foals. Prostitution in itself was not illegal, nor was being pregnant while selling sex, but paying a mare for the sole purpose of breeding had been illegal for centuries.

“Luna,” Celestia began, “let it be known that Twilight Sparkle’s experiments may continue.” Her voice was stern and grim, but not unkind. “Should any foals resulting from this experimentation be unwanted by their mothers or father, they may be taken as wards of the crown; a monthly stipend will be paid to their parents should they choose to keep them.” She cleared her throat and ensured her sister was indeed recording her decree. “Should Twilight so choose to continue her work, the crown must be given weekly reports on her experiments, and the health of her assistants.”

“I’m glad you have seen fit to let her continue, sister,” Luna said, binding the letter with her wax seal, then pressing Celestia’s own into a bit of golden wax next to it. She hoped Twilight would find a solution, albeit a temporary one, especially with such a bottleneck in Equestria’s future. With a flick of her magic, the letter was well on its way.

_-_-_-_-_

Twilight Sparkle read and re-read the letter a dozen times to be sure her first thoughts were correct. She could hardly contain her excitement; the approval of the princesses, no matter how short the leash they allowed her, gave her experiments legitimacy, the one thing she needed to alleviate any doubts that may arise when she informed Cheerilee and Derpy of what their job entailed. She had, by her count, forty-five or so minutes until the first interview of the day, none other than Cheerilee herself, and with the official documents allowing her research, Twilight felt she would have no trouble convincing the teacher to sign on.

She paced in the library, decidedly uncomfortable in her simple attire. It wasn’t so much that her jeans were too low-quality for her, as she’d long grown accustomed to wearing them, as it was simple restriction of movement. Spike, in his diligence, had made sure to buy her a pair with extra room in the front, but had neglected the rest of her measurements, which left her firm ass feeling as though somepony was squeezing it. While the sensation was not at all unwelcome, she much preferred the ability to walk comfortably; as nice as the denim was rubbing against her semi-hard shaft, she needed to head upstairs and change into something a little roomier, or she’d be distracted.

Once at her closet, she pulled it open to reveal a range of clothing, most of which was created long before her new attachment, so half of the items were discarded immediately. Thankfully, her top half remained relatively unchanged, but her breasts did seem a little bigger. She stripped as soon as she could, giving a soft sigh as her bra released her pert bosom; she opted not to replace it, as her breasts felt rather tender. Glancing at the clothes that remained in the possible pile, Twilight saw a few pieces that would work well, both slightly relaxed and keeping the signs of professionalism.

First, she selected a pair of opaque black pantyhose and slipped into them, giving a relieved sigh as the breathable fabric put only a bit of pressure on her, just enough for her to feel it, but not so much as to be restricting. Next, she selected a loose fitting, white blouse, a gift she’d received from Rarity that she’d never had a reason to wear; it still smelled of her friend’s perfume, despite being locked up for a few months. Once buttoned up just above her ample cleavage, she slipped on a woolen vest, one she had had for years, and was now being stretched to meet her larger physique. The vest barely covered her midriff from all she’d grown during her time as a princess, and wasn’t helped by her larger bust. Selecting a bluish-purple, thigh length skirt, she slipped her legs in and pulled it to her waist, smirking to herself as it hid her extra equipment nicely enough. Next came a matching blazer, which bore the same colours as her skirt; she eased into it, then glanced into her mirror, smiling at her reflection; anypony else would think she was heading to dinner with her brother and Cadance.

Worried she was out of time, Twilight looked to her clock, and sighed in relief; she had about thirty minutes until Cheerilee was supposed to drop in, which gave her all the time she needed to relax and unwind in her usual way: a good book. She found it difficult to focus on the pages, however, as the seconds ticked by; partly due to her own nervousness, and partly to a different sort of anxiety that stirred in her blood. A portion of her was male, and that bit was very prone to asserting itself over her right mind, especially as her body realized what Cheerilee's agreement meant. Her brain was determined to keep things civil and strictly professional until she had interviewed both her remaining applicants and gotten their answers; her cock was interested in tossing her mental processes to the wind.

The bell above the door chimed as somepony walked in, and Twilight scurried to greet them, making sure to keep her book at waist height. As if summoned by her thoughts, Cheerilee stepped into the library’s front room. She was dressed in her simple way, wearing a grey blouse and light pink skirt that reached her knees; she seemed a bit more active than most ponies were this close to lunch. Then again, she was a teacher, and years of working with foals who got groggy near mealtimes had probably trained her to take the mid-morning hunger better than most.

“Good morning, Twilight,” she said, closing the door behind her. “Sorry if I’m late; my clock’s batteries died.” Cheerilee seemed entirely genuine, so Twilight did not think she was making a joke about her punctuality. “I’m not too late, am I?”

“No,” the princess replied, “you’re actually about ten minutes early.” Cheerilee breathed a sigh of relief, glad the opportunity hadn’t been missed; fifty bits per day was nothing to scoff at. Only the most dangerous of jobs offered that much, but for something as simple as a lab assistant, it seemed nearly too good to be true; Princess Twilight must have been in a generous mood to offer a position with that sort of salary, especially for the amount of physical labor the ad hinted at. “Well, might as well get started. Please, take a seat.” The school teacher did as asked, yet the town librarian remained standing. “Now, I’m sure you’ve noticed that there seem to be more mares than stallions.”

“Well, there are more fillies than colts in my classes,” Cheerilee said, thinking back to her own graduating year. She remembered ten stallions in all, the same ten she’d known her entire life, the same ten she started school with; there were never any more, nor any less, than those ten. She had never paid it much mind, but it did seem a bit strange when she factored in what she knew of probability and punnett squares. “I’ve actually always wondered why, though.”

“You and most of the scientific community, actually.” Twilight put her hands on her desk and leaned forward, basic body language to let Cheerilee know what she was saying was to be taken seriously. “For years, decades, perhaps longer in an unofficial capacity, ponies have been trying to find a solution. Dozens of breeding programs have failed to stabilize test populations, and we’re basically back where we started.”

“But what about that colt-only spell?” Cheerilee asked. The spell itself was common knowledge, and available in liquid form for use by non-unicorns, so she wasn’t too sure why the numbers still weren’t even. “I mean, it works, doesn’t it?”

“Oh, it works just fine, but the number of stallions available for breeding is still too low,” Twilight replied, bringing a book from under her desk. For a moment, the teacher felt a bit guilty for interrupting her reading time, knowing the princess’s bookworm tendencies. “Even if every stallion sired three colts, the only thing it would cause is a massive linking of Equestria’s family lines.” She ran her hand through her mane and sighed. “After a few generations, inbreeding would be worryingly common.” Twilight reached for a folder, and slid it to Cheerilee for her to see. “Numbers have been crunched, and as unbelievable as it seems, ponykind may well be doomed in the long run unless a better solution is found.”

“And you’re working on a solution yourself?” the teacher asked, putting a few pieces together for herself. When Twilight nodded, she thought she’d figured out some of the princess’s secrets, the reasoning behind the vague advertisement and odd testing done during the application process. “So, what sort of experiments will I be helping with? You know I’m not exactly a biologist.”

“What I’m proposing is, well, a tiny bit illegal,” Twilight said, trailing off at the end until her voice was only a whisper and she sulked in her seat to avoid whatever negative reaction Cheerilee might have had. “But, the princesses have given me their approval, and we’re exempt from the law for the time being,” she added, quick to prove she wasn’t going to be making Cheerilee a criminal any time soon. She showed the teacher the scroll bearing her signed pardon, but kept the content concealed for the time being. “The goal is to reliably produce stallions, so, I needed the assistants as volunteers.”

“Produce… stallions? So what, are you asking me to volunteer myself as a surrogate to some random stallion?” The entire notion was more than enough for Cheerilee to prepare herself to walk out the door if her host failed to explain herself. It took only a moment for Twilight to stand, pushing her hips forward as she did so, and creating a rather noticeable bulge in her skirt. The teacher looked at it, then the princess’s face, then back to the distortion of cloth in question, before finally finding the nerve to speak her mind. “Is that a… dick?”

“Yes; I couldn’t just get any random stallion for this,” Twilight answered, lifting the hem of her skirt to reveal her stallionhood. “Like I said earlier, using existing stallions will result in a bottleneck, but if we can find a way for mares to produce colts using only their own genes, then the issue is handled.” The princess saw the stunned look on Cheerilee’s face, and quickly hid her organ behind the curtain of her skirt to avoid causing her any more trauma. “Again, you can say no if you wish, but I must ask that you maintain total secrecy about what you’ve seen if you decide to walk away.”

Much to Twilight’s disappointment, her possible volunteer seemed to take her up on the offer to leave, standing as she made to walk away. It was only after a moment that the princess realized she was actually walking towards her instead of the door. She jumped as the shorter mare’s hand came to rest over her shaft. “I’ve heard of some mares using spells like this, but always heard they only fired blanks.” Even as Twilight tried to remain scientific about things, she couldn’t help but tense as Cheerilee kneeled to better level herself with the object of her curiosity. “You think this,” she began, fondling over the length of rigid flesh held tight against the princess’s thigh, “can do what others can’t?”

“I-in theory, yes,” she replied, shivering under the foreign touch. She had barely grown accustomed to her own hand, much less that of another; she was beginning to think she’d bitten off more than she could chew by taking on assistants so soon. “But, we don’t have the proper equipment up here; all the insemination instruments are in my lab.”

“Oh, I’m sure we can make do if we go upstairs,” Cheerilee said, grabbing Twilight by the hand and beckoning her forward. Though originally apprehensive, the idea of a good fuck was starting to grow on her, and despite, or perhaps because of, the oddity of the situation, she found herself nearly as aroused as the princess seemed to be. “If you’ll show me to your room, I’ll show you how natural insemination can be much more enjoyable than your clinical process.”

Twilight, unsure of what to do, led the teacher upstairs to her room. With surprising ferocity, Cheerilee pushed the alicorn onto her bed, quickly climbing over her laying form. Sliding a hand up the princess’s skirt, the earth pony massaged the hard length through her pantyhose, locking eyes with the cock’s owner; she licked her lips as she thought about all the wonderful things she’d do. With a quick glance up, Cheerilee rolled away and moved to the head of the bed, smirking at what she found just barely within sight of her earlier position. “Interesting. Are you helping the local Filly Scouts with their knot work?”

Twilight’s cheeks lit up with embarrassment as she saw the lengths of rope Cheerilee had gotten ahold of, but remained still as the earth pony grabbed one of her arms. “C-Cheerilee! W-what are you doing?” In no time at all, her wrist was tied to the bedpost; Cheerilee remained silent, but obliged the cocked mare with a grin. Rolling over to the other side of the bed, the teacher found the first rope’s twin, and did not hesitate to bind the alicorn’s free limb. It was simplicity itself to finish the job, and she made use of another pair of ropes to fully restraint the princess, tying her legs to the last posts. Blushing furiously, but not resisting, Twilight looked down at the suddenly-ravenous mare. With her elbows resting on the bed, Cheerilee met her gaze from between the princess’s legs, and finally spoke.

“Well, we might as well enjoy it, right?” she asked, pulling Twilight’s pantyhose down. The cock the thin fabric once held in check bobbed free, throbbing with every beat of its owner’s heart. Cheerilee gave the shaft a gentle stroke, and had to suppress a laugh as her captive’s legs trembled. “Hmm, this should be fun,” she said in a purring, sultry tone. She gripped the princess’s cock tighter, and had a realization as a whine peeled through the air above her. “Are you not used to having this, your highness?”

Twilight winced at the sensations, and shook her head; it was the honest truth that she had little call to touch herself with anything other than her magic, and her hand was a fluke brought on by arousal she hadn’t experienced much before. Her eyes, once closed as she fought to maintain her composure, shot open as something warm and wet dragged over her shaft, flicking over her tip as it came free. Cheerilee's lips curled into a smile as she open her mouth, a hungry glint shining in her eyes; Twilight realized what the teacher intended, and braced herself for it.

Amazingly, she did not lose control as Cheerilee took her cock into her mouth, though those warm confines and her swirling tongue were more than enough to sap any tension from her trembling legs. Very slowly, the older mare bobbed her head, taking her time to either torture her captive, or prolong her own pleasure; Twilight didn't care which, so long as she kept it up. Something brushed against her nethers, and the princess whimpered as a probing finger slid in. Cheerilee’s digit massaged as it explored, gently rubbing prodding at every crevice it could reach.

“I’m r-really sensitive,” Twilight gasped out. Her cocked pressed against the back of the teacher’s throat, and Cheerilee flt that was the best time to start humming. Her breath hitched as her stomach cramped, and she only had time to slap the mattress once or twice before she lost control. She looked down in time to see Cheerilee’s eyes widen as the first rope of cum shot in her mouth. The teacher pulled back until only the tip was still in, and closed her eyes as she swallowed as much of Twilight’s warm seed as she could.

For a moment, she wanted to apologize, but seeing Cheerilee’s grin kept her from saying anything meaningful. Cheerilee stood and took a step back, sucking the finger she’d used on Twilight, while her other hand was busy under her own skirt. She looked excited in a way Twilight had never been, or at least recalled herself being, and if the princess considering going soft, that look made her cock think otherwise. The earth pony slid her panties down, stepping out of them as she twirled them around a hooked finger. “Take a good look, princess,” she said, stretching the article out so Twilight could see them better. They were soaked through, and she could nearly see Cheerilee’s face behind the semi-transparent fabric.

Slowly, the teacher climbed over the bound princess, straddling one her legs and letting her moist lower lips soak into the lavender fur under the sheer hosiery as she slid up to the alicorn’s crotch. She moaned as the fabric rubbed against her nethers, looking into the princess’s eye as went. Cheerilee lifted off her leg and lined herself up with Twilight’s cock, idling down until she rested on the shaft, pressed between her pussy and the purple mare’s stomach. “Open wide, your highness,” she said, holding up her balled panties.

“Why?” Twilight tried to ask. Instead of voicing her question, her words were muffled by the sudden gag of soaked cloth; though as soon as Cheerilee’s honey hit her tongue, she lost all will to object. The teacher was sweet with a tart edge, a flavor that spread through her entire mouth and sent shivers down her spine. She could have removed the improvised gag any time she wished, but for the time being, she was content to see how things played out. Cheerilee smiled down at Twilight, lifting her skirt to show her soaked nethers, and raised herself off the princess’s cock.

The teacher didn't say a word as she slid down, easing the alicorn's stallionhood in; she relished in the sensation, so much better than anything a toy could provide. Biting her lip Cheerilee looked down to see how much she had taken in,and smirked as she saw how much of Twilight’s cock she still had left to take; just over half of the hard shaft was still waiting for its chance to be held by her. The earth pony braced a hand against the princess’s chest to steady herself, careful to maintain her altitude; she made good use of her flexing muscles, contracting over the dick she so loved to tease, and loving every twitch and murmur Twilight made under her. “Does that feel good, princess?” she asked, sliding her hips forward. The alicorn went to spit the panties out, but Cheerilee placed her other hand over the lavender mare’s muzzle. She leaned in close to whisper, her voice barely audible, but stern and entirely commanding. “Just give me a nod.”

A new wave of excitement through Twilight as she nodded, desperately wanting to be deep inside the mare straddling her crotch. She tried to move deeper, Cheerilee moved away just as much, wagging a finger in the princess’s face. “Did I say you could move, your highness?” she asked as the alicorn whined and shook her head. “Go on, back down with you!” she commanded. Giving a muffled whimper, Twilight did as instructed, laying back and pulling away until only her tip was still making contact. She silently pleaded with Cheerilee not to torture her much longer; as much as the princess wanted it to be untrue, the teacher’s pussy was infinitely better than her own hand or magic, so much so that the only reason she hadn’t cum again already was her earlier orgasm.

Twilight’s eyes shot wide open as Cheerilee thrust herself down, taking all of her length with ease, struggling as she tried to bite back a ragged gasp as she felt her entire stallionhood swallowed by the slick, tight tunnel. The teacher panted as she got used to the feeling of a real cock once more, regretting only that she had not started this so-called experiment sooner; she’d made do with toys and her own imagination for far too long, and she was going to enjoy riding this mare for all she was worth. Cheerilee rose and slid back down, moaning as she felt nerves long left unattended spark to life. She began to speak, but jerked to a halt as Twilight shot a glob of pre that burned a warm trail as it joined the rest of their mixing fluids. “Consider this my signature,” she managed to say, almost too caught up in her own pleasure to bother.

Everything about this was perfect in the teacher's mind; she had a pretty, younger mare tied to a bed as she rode a hard, hot cock into bliss. Cheerilee leaned back to angle Twilight's stallionhood against her front wall, bracing one hand on the mattress behind her as she bounced on the princess’s rod. Smiling devilishly at the look of blissful pleasure on Twilight’s face, she realized her captive royal may not last much longer. Eager to speed up the process, and hoping to see the librarian’s face in agonizing rapture, she thrust her free hand behind the princess’s sack.

Cheerilee plunged two fingers through Twilight’s soaked lips, effortlessly gliding into her spasming pussy. The alicorn writhed and bucked against the stimulation, thrusting wildly against her captor in an attempt to maximize her own enjoyment. The princess’s breath caught in her throat as her stomach started to cram up, giving her only enough time to let out a strangled, muffled groan as her body slipped from her own control. Twilight pushed as deep as she could, burying herself to the hilt as she came. Cheerilee had different plans.

The teacher pulled herself off the librarian’s cock in time to aim the first shot of cum; with a twitch of the alicorn's cock, a rope of her thick seed splashed across Twilight’s muzzle. The next burst went higher, landing on Twilight’s eye and mane. The next globs stained her clothes as they hit her body, still copious enough to hint ooze and spread across more of the purple fabric as it soaked in. The last shot, the weakest and thinnest, landed in Cheerilee’s hand, who cupped it in her palm. “Oh, princess, don’t think we’re done just yet,” she said, massaging the cum she held into the head of Twilight’s cock.

_-_-_-_-_

Spike sat in the foyer, as he often did when Twilight was busy; he only knew she was busy because the book she’d been reading was still open on her desk, and she was nowhere to be found. He took that to mean Cheerilee had accepted, and he believed they were in the basement running fertility tests and other such things he didn’t want to think about. For him, a young dragon well into his teens, sex was something he desired in copious amounts, though all desire left when his adoptive sister was the object of his thoughts. Thankfully, in line with the dubious legality of the experiment she would be assisting Twilight with, the library’s main rooms were soundproofed from the rest of the house, so nopony browsing for books would be disturbed in any sense of the word. Like many teenaged stallion, he passed his time of boredom and tending the library with a few chapters of a science fiction novel he’d found in the basement.

A knock at the door grabbed his attention; he checked the clock and realized the time for Twilight’s second appointment of the day was quickly approaching. He marked his page and stood, adjusting his jeans as he walked to the door; it would not do for his ants to fall down as he greeted the second possible volunteer. Straightening his shirt, he opened the door, unsure of what sort of mare Twilight had found; he partially expected some local waitress or something, somepony down on her luck who needed the money and didn’t mind the possibility of going to jail. What he saw as he opened the door was far from his expectations.

Grey-furred and blonde, the mare stood a bit taller than he did. She looked at his with yellow eyes, and smiled warmly. She was older than Spike, that much he knew based on Twilight’s requirements, though her age did little to subtract from her looks. This mare, a pegasus by the wing on her back, was like many of her kind: she was lithe, with thin thighs and a small frame. Her hips and bust were larger than most pegasi, more in line with unicorns than one would expect. She wore a form-fitting, grey uniform that matched her coat and bore the patches of a postal worker, though her name tag was noticeably absent.

“Hello there, I’m Derpy Hooves.”

The Error in Communication

Derpy Hooves, Ponyville’s resident mailmare, was what some ponies would call an enigma; she had a family, but never married, and while she seemed to have quite a thriving social life, most ponies in town knew nothing about her. She was, as many stallions in town thought, enticingly beautiful, the sort of mare who had an air about her that complemented her appearance with the sort of grace only the sure-footed could possess. She was also holding out a hand for Spike to shake and introduce himself. “Oh, hi; I’m Spike, Twilight’s assistant,” he said, clumsily shaking her hand. For a moment, Derpy's yellow eyes moved away from each other, and the teenaged drake was worried for her health until he saw them settle back in place.

“Well, Spike, I hope we get to work together,” she replied in a singsong voice. The dragon took a step back and motioned for her to walk in, and did what any male would do by sneaking a peek as she stepped onto the wooden floor. He expected to see a normal ass, the small, toned behind associated with pegasi, but was amazed to see it bounce as she walked, restrained only by her shorts. “You know, as long as I’ve lived here in town, I’ve never been in here before.” Spike was enraptured by the blonde's swaying hips; something stirred inside him as he watched her walk about the library. The feelings were centered around Derpy, the way she moved, the way she looked, even the way her eyes crossed when she turned her head too fast; the dragon wasn't to sure what his gut was saying, but it felt something like hunger, only focused on a pony. He wanted to... bite her? Or something like that; wasn't quite sure what his body was telling him. “I usually use the bookstore across town.”

“W-well our books are free if you bring them back,” Spike replied, catching himself as he closed the door. He was surprised to see Derpy whip around and smile, her eyes wonky; the dragon assumed it happened when she was excited or happy about something, rather than a permanent issue, given that such an impediment would make it impossible for her to fly around delivering mail.

“I’ll have to come back sometime, then,” she said, setting a small bag of bits on the desk; she figured she wouldn’t be needing it today. She was there for business, well-paying business, and getting distracted looking for a book for Dinky wouldn’t be good if she made a bad impression on Spike or Twilight. “Sorry, but do you know where Twilight is right now?”

“I think she’s in the lab with the other applicant,” Spike replied, unsure of where Twilight actually was; he hadn’t seen her all day, and was working off assumptions. “Come on; she should be finishing up soon,” he explained, motioning for Derpy to follow him. He didn’t know how much Derpy had been told of the situation, or even if Twilight had mentioned anything at all, but he figured it would be safe to take her to the labspace, especially if she would be spending a lot of her time down there in the future.

The basement, originally carved from the massive library's roots, had been expanded over the years until it had nearly as much floor space as the rest of the building. Much of the equipment that filled the lab was almost generic for anypony not familiar with their function; everything of a sensitive or possibly illegal nature was covered by a sterile, white sheet. A few large syringes, the sort lacking needles because they were meant for a different sort of injection, were laid on a table next to what Spike knew to be a gynecological exam chair, free to see for any pony who might walk in. Thankfully, any of Twilight's obscene accessories were out of sight; the dragon imagined Derpy would be much more likely to refuse if she saw a hollow dildo with a plastic tube running from the base.

With the labspace mostly free of dangerous objects, Spike's attention was free to wander as the mailmare checked over everything not obviously meant to be hidden. It did not take long for the dragon's hormone-addled brain to realize he was in an enclosed space with an attractive mare; the fact said space was meant for reproduction, and had a lingering scent of sweat and other fluids only conspired against his logical mind. As he watched Derpy walk around the lab, carefully inspecting the equipment while making sure not to disturb anything delicate, his eyes drifted over her form. The dragon was certain words for the mailmare's body existed, but they eluded him at the time.

He occupied himself with staring at her, keeping an ear open for any questions she may have had that he could answer. He was enraptured by nearly everything Derpy did, down to the way she brushed her mane from her eyes every time she bent down to check something on a low shelf. With such a display, it didn't take long for his hormones to remind him of his own endowments. Derpy Hooves, for all the unintelligence many ponies attributed to her, was actually very clever; she knew precisely how much of a catch she was, and the effect she was having on Spike. Her body was built for sex, and while she had no intentions of following through, she bent down and picked up a length of plastic tubing that had fallen on the floor.

She wiggled her hips as she picked up the length of tubing, gently flexing her muscled ass as her tail swished from side to side. Spike was treated to more than he thought possible for such a casual encounter; Derpy had either forgotten to wear panties, or simply chose not to for the day, giving him a wonderful view of her slit through the groin of her shorts. Despite the implied vulgarity, the outline of her sex only served to elicit perfectly natural responses within him; his body trembled as his arms tensed, ready to lash out at a moment’s notice. The dragon was primed to take the mailmare as dragons did: pinning her to the ground and claiming her as his own. Spike’s face reddened as he felt his muscles twitch, sending his tail flopping against the ground in time with Derpy’s own; the sound of hard scales smacking the wooden floor filled the lab, loud and oddly funny.

_-_-_-_-_

Upstairs, Cheerilee was quietly stepping out of Twilight’s bedroom. She closed the door, making sure the princess was sound asleep before sneaking downstairs. The teacher drunkenly stumbled down the stairs, wincing as feeling returned to her legs with every half-silent stride; she hadn’t expected the princess to turn the tables on her like that, but even if she suffered a few phantom sensations, it was well worth it in her book. She braced herself against a handrail and shivered as a lingering shot of lightning ran up her spine; despite the rough treatment she’d received, and being as satisfied as she had ever been, part of her wasn’t quite done. A naughty thought ran through her head as she remembered she hadn’t seen the lab yet, and what sort of assistant would she be if she let Twilight go about this experiment without the proper equipment?

Smiling to herself, the well-sexed teacher hobbled downstairs, hungry to see what goodies the princess had hidden away underground, and equally hungry to try a few of them out before business took precedence. The entire upstairs, even the staircase itself, was soundproofed so her uncoordinated steps were barely louder than a mouse’s; she was even pleasantly surprised to find the door to the lab unlocked. Like an inebriated cat, she slinked inside, careful not to disturb anything on her way. A pair of ponies laughed as Cheerilee stepped into the lab, though she could tell their amusement was not directed at her. Slipping her heels off, the teacher made a conscious effort to maintain silence as she sneaked up on the unsuspecting ponies.

She saw them rummaging through the more expensive-looking pieces, a grey mare and a purple stallion, and for a moment, thought they were there to steal, or expose the experiments to the public. But, after only a few moments of fear and anger, she saw that the stallion was indeed Spike, along with a local mailmare by the name of Derpy Hooves; Cheerilee surmised the pegasus was her competition in getting a position as a lab tech, but she felt her own acceptance was in the bag. The dragon, who even in the worst of lighting looked like a primed hunter, looked menacing in the bright beams shining from the overhead lamps; in the teacher’s addled brain, the genuine male she saw standing tall before her was many times more appealing than her previous partner, even if there was a very good chance she would be on the receiving end of anything he could dish out.

The drake’s tail thrashed about on the floor as she sneaked up behind him, masking her steps with ease. Spike was alluring in a way Cheerilee could not really describe, and she liked to think of herself as a very learned mare; something about the dragon simply could not be quantified in her mind, save for the fact she wouldn’t mind seeing him naked, preferably on top of her. She strided up to him from behind, running two fingers up his tail as she went; her heels clacked on the floor as she dropped them in favor of gripping the very base of his muscular tail. “Hello, Spike,” she huskily said into his ear. “I was wondering if you’ve ever done any experimenting, and I mean the fun sort?”

Derpy stopped what she was doing the moment she heard Cheerilee’s heels hit the floor; she hadn’t heard the other mare walk in, but between browsing the labspace and Spike’s flopping tail, she hadn’t been able to hear much that wasn’t obvious. The mailmare didn’t like much of what she saw; ignoring the fact the dragon looked uncomfortable in the teacher’s grasp, she reeked of sex. Derpy had heard Cheerilee was a good mare, honest and caring, but sleeping with the boss may not have been beneath her; there was a certain sense of betrayal involved, what with Derpy’s own daughter being taught by the other mare. The teacher didn’t have the expenses the Hooves family had, and while the pegasus wouldn’t leave any possibility unchecked when it came to taking care of her family, she wouldn’t sleeze her way into a position when somepony else needed it more.

Derpy glowered at both of them, angry enough at losing the job to some slut and strung along under false pretenses. Spike may have been innocent in this, and showed no signs of being Cheerilee’s interviewer or having had any sort of intimate interaction with her, barring the current molestation he was suffering; Cheerilee, on the other hand, would never have Derpy’s forgiveness, not for closing off this line of bits, money Derpy needed to provide for her family. Her wings flared out, primed to launch her either up or forward, but she calmed them down, biting her anger until she could think somewhat rationally. Instead of doing what she really wanted, more out of avoiding time in prison than genuine desire to leave Cheerilee unharmed, she stormed past them, half-running until she was up the stairs and out the front door; she even had the presence of mind to quietly close it behind her to avoid bothering the neighbors.

“Wonder what her problem is,” Cheerilee said after a few moments, letting go of Spike’s tail in favor adjusting her clothes; she hadn’t meant to be so unkempt, but circumstance seemed to have conspired against her. She looked Spike up and down to gauge his reaction to Derpy’s leaving, but he seemed a bit stunned; the bulge in the front of his pants, however, seemed fully appreciative of her earlier efforts. She doubted she had the time to have any real fun, so she decided to give the dragon a taste of what she had to offer, a little something to hold him over until she had time to fool around. With the dragon unresponsive, Cheerilee hiked her skirt up and pressed her ass against the base of his tail; the teacher grinned as she slid down the muscular appendage, shuddering as she passed over each dull spine that decorated its length. Triumphant, she grabbed her discarded shoes with a smile.

“Can we head upstairs now?” the drake asked as Cheerilee stood once more. He felt rather odd about the entire day; while it was not the first time a mare had felt him up, but it was the first time anypony had taken offense to seeing it.

“Now Spike, as much as I’d like to take you upstairs, I really do need to be going,” the earth pony replied, slipping into her heels while she finished buttoning up her shirt. She looked over the him, an embarrassed look in her eyes. “Don’t tell Twilight, but I have another interview today.”

As quietly and quickly as Cheerilee had creeped down the stairs, she nearly ran up them as made her way to whatever she had planned later in the day, leaving Spike alone in a sex lab with just his thoughts and an oddly persistent erection. Wondering where his life was going, he shook his head and followed the mares’ examples by slowly climbing to the ground floor; He flopped down in his chair and grabbed his book, content to sit down and read until time for bed. He opened the novel and propped his feet up. The drake flinched as hit clawed foot sent something clanging to the floor, and he jumped up to see what it was. “Oh, Derpy’s bits purse; she might want this back,” he said to himself, also aware that being nice to her would hopefully negate any ire he may have earned from Cheerilee’s earlier display.

The weather outside, however, was less than agreeable; dark stormclouds hung in sky, and the air was heavy as the scent of water wafted on a hot breeze. Still, Spike felt a bit bad about offending the mailmare, even if it wasn’t his fault. As he stepped outside into the afternoon heat, a clap of thunder echoed through the town’s empty streets; most of Ponyville’s residents had locked themselves in their homes for the day, as the storm wasn’t scheduled to end until early the next morning. Unsure of how else to begin, Spike took the first step in what was shaping up to be a long and tedious journey to return a small sum of coin to a pegasus whose house he had never seen.

_-_-_-_-_

There were few things in life that relaxed Derpy quite like a hot bath; letting the bath run while she lit up some old candles that really had no business going unburned after so many months. While the tub filled, she entered Sparkler’s room and moved to the bookshelf that dominated one wall. Unsure of what to read, she let her hand roam over the spines of Sparkler’s collection until she stopped randomly. Pulling it out, she cocked her head as she read over the title; the cover was rather risque for a book that was in reach of her youngest daughter, showing a female griffon wearing perilously little as a horned, silhouetted male hung in the backgroud, draping a hand over the griffon’s hip.

“The Lusty Griffonian Maid?” she asked aloud, shrugging as she made up her mind that this book would have to suffice even if she had never heard of this ‘Ferrous Resolve’ or read any of his or her previous works. Derpy took the book and made note of where she got it from, then returned to the bathroom just in time to see the water at the level she wanted. Dinky was downstairs, playing in the living room, being a good little filly while her mother tried to shake off the day’s events; without needing to be a responsible adult for a while, the mailmare was able to truly unwind.

Derpy undid her shirt and dropped her shorts before tossing them both into the hamper. She reached behind her back and undid the hooks on her bra, sighing as her breasts popped free; her panties followed soon after, letting her bouncy rump loose to the open air. The mailmare grinned at the bright yellow Bubble Butt caption on the ass before she threw them aside. She turned and gave herself a once-over in the mirror, posing a few times to get the best view. “Ha. I look better than that skank,” she mumbled, hefting a breast in each hand as she mimed a kiss to her reflection. She turned her back to the glass and bent over, looking over her shoulder as she smacked her ass one good time; the sensation was odd, but the stinging was pleasant, something she hadn’t felt in a little over nine years.

Relatively tame, yes, but that was all she allowed herself; she hadn’t had time for a relationship, let alone sex, since Dinky was born. Likewise, what little time she had to take care of her urges alone was scant, so she barely had the opportunity to take care of her own urges; as she eased into the bathwater and grabbed her borrowed book, she knew this sort of relaxation did not involve her playing with herself. As the bath’s hot water soaked through her fur and feathers, her muscles relaxed and she very briefly forgot the day’s troubles; the book, as trashy as it seemed, was written fairly well, and set around a scullery maid named Eos as she went about her chores in her master’s house. While the book’s thickness hinted that there was an overarching plot, little was to be found within the first chapter.

The master of the house, Apis, was a minotaur described in lurid detail as a hulking example of his race, lord of a town in the middle of a temperate kingdom; he was harsh, but fair, a good lord in a crowd of equally wonderful lords and ladies. He kept a small staff, almost too small for his large manor, but he was intimately familiar with each of his workers; there wasn’t a single servant of his that he could not name their birthday, anniversary of their first day on the job, their spouse’s name if they had one, the names and birthdays of any children, and the list went on and on. It seemed as if Lord Apis was a solitary figure heading a township by charisma and a wonderfully political nature, but, as Eos was quick to point out in her narration, solitary was an unfortunate condition that none of the townsfolk could seem to remedy.

For years upon years, the townsfolk had been trying to find the perfect cow for their bull, with minimal success. Apis would begin the courting process, then find some flaw or some reason not to continue along with that particular one, and broke things things off, ever in a polite way. When the supply of eligible females in his fiefdom was exhausted, concerned residents began sending letters to nearby lords, each asking for a wonderful match for Apis. Each search was fruitless, but as Eos was quick to add, unnecessary. Enthralled, Derpy wondered why the search was unneeded, especially in such a time when inheritance was so important, and under so loved a ruler. That curiosity was rewarded when Apis lifted Eos off her paws and carried her into his chambers.

The sudden jump from storytelling to blatant erotica was jarring, but as the mailmare continued to read on as Eos slipped under Apis’s armor and undid the straps holding his loincloth up, she found herself mimicking the griffin’s own feelings as her body heated up, independant of the bathwater. Derpy’s hand followed Apis’s, doing to her own body what he did to Eos, teasing her way down her neck, to her breasts, and finally easing between her legs. She rubbed over her slit once, before gently easing a finger in.

“Mama, Spike’s here; he brought your purse,” Dinky said through the door, sounding oddly excited about something. Derpy nearly jumped out of the tub, heart pounding a mile a minute; it wasn’t often Dinky or Sparkler scared her, but when it happened, it was rather serious.

“Just a minute, honey; tell him I’ll be right there,” she replied, quickly grabbing a towel. She wasn’t surprised to know Dinky knew Spike, especially with the free lessons Twilight had been offering at the library for some time now; she was more surprised that the dragon had come to her house to return the bits purse she hadn’t known she’d left. She looked herself over in the mirror, from flushed face and hard nipples to ready sex and shaking thighs; shaking her head, the mailmare exchanged the usual towel for the one she used at the beach, intent on covering her body as much as possible. Catching her breath, she stepped into the hall, and rounded a corner to the stairs.

Spike was right near the door, where he was always taught to stand when the head of the house had yet to invite him to sit; Derpy locked eyes with him as she glided down the steps. She wondered just what sort of dragon he was, returning the money when he could have at least had a bit of fun with a ready and willing mare of… experience. If she was right, judging by the rain pouring down outside and the fact Spike’s clothes were soaked through, then he was either entirely selfless or thought this was a way to bring her back to the library.

“Please, have a seat in the living room,” Derpy said, opening the door to her bedroom. “I’ll be back out as soon as I’ve changed.” Dinky, seeing her chance, grabbed Spike by the claw and dragged him away, babbling about having somepony to play with. The mailmare shook her head as she closed the door, almost feeling sorry for the poor drake; little Dinky was a shark.

Derpy threw off the towel as soon as the door clicked closed, glad for some privacy once more; thinking ahead, however, she silently cracked it back open to eavesdrop on her unexpected visitor. The towel was thankfully thick enough to hide her arousal, but even as she shook off the last vestiges of warmth, some still lingered deep within. Quickly, she threw on a large shirt, one she’d owned since her high school days that was so faded the lettering had worn away; it looked more like a short dress than a shirt, but it was broken in and more comfortable on her wings than most newer clothes. She slipped on another pair of panties, a black pair with lace that she only ever wore when out with her friend Berry, though that was more a choice of comfort than flirtation.

“I thought grown-ups were supposed to be good at poker,” Dinky shouted from the living room. Derpy suppressed a giggle at the groan that followed as Spike surely lost a lot of chips.

“Who taught you to play? Twilight never covered this in Twilight Time,” she heard the dragon grumble out, followed by the sound of cardboard slapping against wood. She peeked through the crack in the door to see her daughter and the dragon happily playing poker; she would have also been disappointed in Dinky playing for actual money, but judging by the small pile of bits she had racked up, she was at least playing it safe. Her gaze slowly honed in on Spike, however, despite the overall image of his interactions with Dinky.

He looked to be in his late teens, perhaps closer to twenty than first glance would suggest; he was surprisingly happy to be losing, even though Derpy was sure he was being taken for all he had. Whatever the case, Spike seemed good with foals, which was unusual for ponies his age, but the mailmare was quick to remind herself that he wasn’t a pony, and that dragons may have matured differently. Even then, there were more than a few analogues that made the drake easy to empathize with; if she ignored the scales, he looked very nearly like a stallion, one whom her daughter seemed to love the company of, and, as odd as it was for Derpy to think, she founder herself agreeing for reasons of her own.

Spike was clad in a white t-shirt, soaked through to the point his purple-green hide showed through, and his lean, serpentine figure was for all the world to see. He wasn’t rippling with muscle, nor was he scrawny, and she could certainly see why, when she picked up Dinky from her first Twilight Time, the group seemed to be full of just fillies, most of whom were teenagers.

“Oh, come on!” the dragon groaned as he lost yet another hand; he slid over the last of his bits while Dinky smirked at him. He shot back a grin of his own. “You may have won the battle, Dinky, but I have won the war.”

“Oh yeah? How?” the little unicorn asked, looking at her piles of hard-won money. Sparkler had taught her how to play when she was six, and she’d proven a master very quickly; even Derpy’s maternal instinct couldn’t get through her poker face.

“Like this!” Spike quietly roared while lunging forward; Dinky tried to protect her stash, but the drake wasn’t after the gold for once. Instead, he gently picked she up and pulled her to his chest, running his claws over her ribs while his arms held her in place. She cackled and gasped, finally breaking free.

“Ew, Spike, my clothes are all wet now!” the unicorn said, trying to keep her mane from dripping any worse than it already was; most of the moisture in Spike’s shirt had transferred to the back of hers. “Mama,” she started, seeing her mother standing in the doorway. “Can I go change really quick?”

“Of course, sweetie,” Derpy replied. “Let me go get you two some towels, then after you get dried off and dressed, we can see about dinner.” The downside of being busy in the early morning meant she had no idea what to cook, as she hadn’t taken the time to plan during the day; now she had to incorporate a fourth appetite and palate, but the burden was made easier with Sparkler out at a friend’s house for the night. “I’ll be back down in just a minute, okay? Don’t send the poor colt to the poorhouse while I’m gone.”

“Okay,” Dinky half-whined, but one could hear she was joking; she would obey her mother’s wishes, if only in spirit.

“Oh, and Spike?” the mailmare started, looking over her shoulder as she started up the stairs. She contained a chuckle as the dragon snapped his attention to her; for a brief moment, it looked like he was actively trying to avoid looking at her. Manners, perhaps? Maybe he was hoping to avoid any suspicion to ogling her, or perhaps he was overcompensating for actually looking a bit longer than was strictly necessary.

“Yes, Miss Hooves?” Spike asked, looking a bit nervous. Had she scared him a bit? Derpy wasn’t sure, to be honest, but she knew something had to change, at least to boost the poor dear’s confidence.

“Please, call me Derpy,” she replied, smiling as relief crossed the dragon’s face. Whatever the reason for his nervousness, she had at least abated it for the time being. “Would swim trunks be okay for you to sleep in, if the storm doesn’t let up after dinner and you need to stay over?”

“Oh, of course,” he answered, looking a bit confused about why she would be planning on him sleeping over, or perhaps about the fact she owned swim trunks when she only had daughters.

“Alright then; I’ll be back in just minute,” she said one final time, before heading upstairs. At first, she expected to hear them go back to playing, but as she stepped around the corner and listened, she heard very little in the way of games.

“See something you like, Spike?” she heard Dinky ask, barely loud enough for her to hear. They must have thought she had gone straight to the bathroom if the unicorn was speaking so clearly.

“Yes,” the dragon said, almost dumbly. If Spike meant the mailmare, then she was more than flattered, even if she knew how desirable she was. Still, to have a teenager openly admit it was a boost she needed on a rainy day, especially after the encounter with Cheerilee and the lost job opportunity. Besides, if Spike had tried to find her house to return the money right away, as his clothes suggested, then he resisted the teacher’s charms; that meant he had a good enough head on his shoulders to do the right thing above personal gratification. That was an admirable trait in one so young.

“She’s single, you know?” Dinky went on, and Derpy did her best not to giggle too loudly. It was sweet of her daughter to try and set her up, but Spike was a bit out of her age range; she shook her head and decided to have a little talk with Dinky as soon as they had a moment alone. Still, Spike didn’t seem to mind too much, the way she knew he was staring...

The Sleepover

Derpy, Dinky, and Spike sat around the kitchen table, munching on some pasta dish the mailmare hadn’t named, but the recipe had been in her family for generations. For the dragon, who was used to eating food he cooked himself, or whatever Twilight had managed to burn to charcoal, it was a welcome change; despite his gem-augmented diet, the meal was rather satisfying. There was a silence over the table, though not an uneasy one; none of the three diners had anything they could openly speak of, nor did they have the desire to interrupt the comfortable blanket of quiet that settled over the Hooves’ house at dinnertime. As the storm raged outside, minds raced and rumbled in time with the thunder, tumultuous and disjointed.

Dinky, seated on one side of the table while her mother and Spike sat opposite one another, could see the entirety of what went on between the two. She was plainly aware of her mother’s suspicions, slowly changing to a kind acceptance, though what any of those lingering doubts were about, her mother had not said. Meanwhile, she noticed the dragon’s hesitance to look at Derpy, afraid his eyes may linger too long and offend; however, she knew what he did not: Derpy very much enjoyed being looked at, even if she never acted on the urges. The entire situation was a bit painful to look at from the outside, especially for the little unicorn; she knew her mother was lonely, scared of being hurt a third time in a row by her poor relationship choices.

From what Sparkler had told her, her father was Derpy’s second coltfriend, though he hadn’t stuck around for very long after discovering she was on the way; Sparkler herself had been sired by Derpy’s high school sweetheart, who shortly thereafter moved to Canterlot and hadn’t even known about being a father. Both young stallions had been charismatic, likeable fellows, and nopony faulted the mailmare for falling for their charms. It didn’t take scorn to feel the pain caused by both incidents, and she had been left with a fear of commitment, worried the next stallion to happen along in her life would break her heart. The very idea of seeing Derpy Hooves, the strongest mare Dinky knew, worried about being hurt was the most painful thing imaginable.

While she knew her mother had a fear of being heartbroken by some silver-tongued stallion, she also knew Spike wasn’t a stallion; the very thing that made him so alien made him the best candidate for a relationship. From the tests she’d run the dragon through, he was everything the last two were not; from the poker games, she knew he was honest, and from the way he handled defeat, as well as throwing a few good hands to spare Dinky’s feelings, she knew he met Derpy’s most prevalent concern about being good with her foals. Honestly, all either of the two needed was a little push in the right direction. But, just what could she do to get them on the right track?

_-_-_-_-_

Spike was unable to really process how his day had gone; it started off fairly normal, or at least as normal as most of his days had been, then everything went a bit sideways. Despite being molested and running through a storm for longer than he wished, his luck seemed to have turned around. Even losing twenty bits to Dinky hadn’t brought his mood down; something just kept him from not liking his situation.

It didn’t hurt that he sat across from Derpy, accidentally stealing glances whenever he looked up. Part of him boiled up in the back of his mind when he looked at her, the same part that made him think strange things about Twilight as of late; at least as it latched onto thoughts of the mailmare, it was clearer about what it meant. Spike hadn’t been this frustrated by his body in a while, though the feelings he had in adolescence were exacerbated by his mind’s broadening, leaving him with a concise idea of what the signals meant, but no way to interpret them. Derpy looked appetizing in a way he could not accurately describe, but he knew it didn’t involve his stomach, so much as organs a little lower.

“May I go bathe now?” Dinky asked, showing manners oddly surprising for one who cheated a dragon out of gold. Derpy looked over at her daughter in confusion, before nodding her head.

“Of course,” she replied, standing up in time with the unicorn. She collected Dinky’s plate and made her way around the table to where Spike sat, looking down at him with a smile. “Are you done?” she asked, gesturing to his cleaned plate.

“Oh, yes,” he said, handing it to her, then mentally kicking himself for assuming she was going to carry it herself. His fears were alleviated as soon when Derpy kept smiling while she collected the dish. Her wing brushed against him as she walked; his tail, formerly lazily wagging to and fro, locked in place as he jumped in his seat a bit. The feeling in the pit of his gut magnified, and a cold fear settled over him as he recalled the the last time he felt a want, a need, on this level; the birthday he lost control of his greed and turned into a monster, he’d felt the same burning desire for new items, new treasures, that he did now. He wasn’t sure if things were better or worse for the lack of a concrete idea or target for his instinctive interests.

“Maybe we should let these soak for a while,” Derpy said, wiping her hands on a dishrag while she walked towards the door. “Maybe you’d like to relax for a bit?” Spike nodded dumbly and followed her into the living room; it was a humble affair with two chairs and a loveseat, all aimed towards the window in case anyone wanted to ponywatch. Almost immediately, the mailmare plopped down on the little, L-shaped couch; it was a delightfully ugly piece of furniture, but it gave the room character Spike had grown accustomed to seeing in the Hooves’ house. Derpy patted the cushion next to her. “Dinky and Sparkler aren’t big fans of other ponies using their chairs, so most guests sit with me.”

“As long as I’m not a bother,” Spike hesitantly said, easing onto the fabric-covered loveseat. He stopped just a few inches from sitting, shifting his hips as he tried to find a way for his tail to rest that wouldn’t leave it crushed under him or against the armrest. “Maybe I should just stand,” he mumbled, almost embarrassed by his extra limb.

“Oh, nonsense!” the mailmare giggled out, raising up and motioning for the drake to move his tail. “Just wrap it behind my back; it’s not like you’ve got a hand on it or anything,” she continued, still a bit bubbly. It was nice to see somepony else dealing with an appendage most ponies didn’t have to work around; her wings must have kept her from wearing as many shirts as the chairs Spike’s tail kept him from using. “Pegasi wrap each other in their wings when they share a sleeping bag like a big, feathery burrito, so this isn’t too different.”

While Spike didn't see how the two were comparable, he shook his head and laughed right along with her as he shifted his appendage around, snaking it until both of them had comfortable seating. Despite his spine being perfectly fine, the drake still sat rigid when Derpy took her seat again, accidently flexing his tail so that it squeezed against mailmare’s ass and thighs; much to his relief, she seemed to understand he had no control over the reflex, or at least took it as a joke, because she laughed and flexed back. Her actions did nothing for the bubbling, greed-like sensation that roiled in his gut, as his mind latched on to every muscle he felt in her lower body, and how wonderful it would be to see them in use.

“Listen, I’m sorry about Dinky taking all your bits,” the mailmare apologized, scooting closer to Spike and handing him a tiny bag full of his bits. “She knows she isn't supposed to scam guests out of bits, but sometimes she gets a bit carried away.”

“Oh, it’s fine; she earned them.” Spike waved a hand in a dismissive gesture, smiling as he curled his tail to make up for the distance Derpy had closed in handing him his money. He was surprised to see she still didn’t mind; if anything, the way she sat and leaned towards him made it seem like she enjoyed the attention. “I wish I knew how to play that well when I was her age; I wouldn't have lost my allowance to Shining Armor so often.”

Derpy laughed along with him, the gears in her head slowly turning as she noticed a few changes in herself; something about Spike, or being in his proximity, did something to her, and if she gave Cheerilee the benefit of the doubt, other mares as well. She’d been unusually playful earlier in the lab, flaunting her body like she was some reckless schoolgirl again, then blown up in Cheerilee’s face faster than was reasonable. She’d nearly masturbated in the tub and risked leaving Dinky unattended for who knows how long, and now she was scooting closer and closer to a dragon half her age because she was following that same arousal that had plagued her since walking into the library. Derpy looked at Spike; even as he blushed under his scales and slightly pressed against her as she cuddled against his side, he seemed to be unaware of his effect on her. The mailmare, however, knew precisely what she was doing to him.

“I’m curious about something, Spike,” she began, pulling his tail over her leg to wrap around her like a belt. She ran a finger up his chest as she spoke, making sure she had his full attention before she continued. “If you’ll indulge me, that is.”

“S-sure, Derpy,” Spike sputtered out, half of his brain unable to process what was happening and the other half wanting to ravish the older mare pressing against him. He yelped as she slipped her hand under his shirt and rubbed over his stomach, tracing her earlier path over his scales; she found he was surprisingly warm for a reptile, which she always assumed would be room temperature due to their cold blood, but Spike was almost like a furnace.

“Do you have any idea what you’ve been doing to me all day?” she asked, her voice barely above a whisper as she slipped his shirt off; she stopped only for a second to eye him in full. Slowly, she grabbed his free hand, and snaked it up her stomach, beneath the soft nightshirt she wore, stopping just beneath the swell of her breast. She swallowed the lump in her throat as the burning heat of her arousal swelled with every centimeter the drake’s claws came closer to her delicate flesh. “I wouldn’t be doing this if there wasn’t something nearly compelling me to, so if you’re doing something to get me this turned on, I want to know what it is.”

Spike shook his head but remained silent as Derpy pulled his hand up, forcing his palm against her pillowy chest; almost on instinct, he massaged the soft flesh, gentle enough not to hurt her on his claws, but firm enough to convey his message. “You don’t know, and here I am nearly throwing myself at you?” she asked, almost playfully, as she scooted into his lap, laying her back against his chest as she pulled off her top; she had an uncurbed exhibitioist streak until Sparkler was about Dinky’s age, so she knew enough to leave her clothes nearby in case of emergency. “Normally, I’d ignore any feelings like these,” she groaned, moving the dragon’s other hand to her neglected breast. “But -oh- I can tell this isn’t going to go away on its own.”

Suddenly, the drake stopped his stimulus, making Derpy jump more than the erection she felt pressing against her ass. “Listen, I-I don’t want to take advantage of you, especially not if I’m doing something I don’t know about,” Spike quickly said, pulling his tail away. Part of his mind railed against him, that greed that wrested control from him once before, but he grit his teeth and forced it down; his resolve remained resolute even as Derpy turned around, straddling him with his face buried between her breasts.

“Spike, whether or not there’s a reason behind it does not change the fact that my body wants you,” the mailmare said, grinding against the bulge in Spike’s pants. She pulled him up, resting her forehead against his as she sighed in contentment; if this was as close to sating those urges as she would get, then she intended to at least make the most of things. Forcing the dragon’s head back, she crashed her lips against his, hoping he would either enjoy it, or understand enough not to be too angry with her. Like the straw that broke the proverbial camel’s back, any resistance to his nature Spike had gave out as his hand flew to Derpy’s hips and pulled her against his straining erection; he really needed to get out of those pants soon, even if he had to rip them off.

A door upstairs opened, and in the time it took for lightning to flash outside, the pegasus and dragon were on their respective ends of the couch, as fully clothed as they had been when they started. “Goodnight, mama,” Dinky called from upstairs as a second door opened and shut, not the energetic half-slam of a young filly, but the exhausted click of a sleepy little unicorn. The pair on the loveseat let out breaths neither knew they were holding. Derpy was the first to make a noise, chuckling to herself as she stood.

“Listen, Spike,” she began, pressing two fingers to her neck to check her pulse. “As much as I enjoy the risk of being caught in the act, I’d prefer neither of my daughters be the one to see me riding somepony on the loveseat.” She held out a hand to help him to his feet, smiling and shaking her head when she saw how his tail wasn’t the only thing scared stiff by the interruption.

“That about killed the mood,” he joked, still dazed from the idea of having sex with the mare every stallion in town knew was impossible to have; he wasn’t one to think of such things, least of all discuss them, but he had ears like everypony else, so he still heard things. “I don’t suppose you have a guest bedroom?”

“Dinky moved into it when she turned seven,” the mailmare replied, still holding Spike’s hand as she walked. “The couch is also too small to sleep on, Dinky’s bed is too small for me to share with her, and neither of us are about to invade Sparkler’s privacy, so I guess we have to bunk together.” While it was a bit late, with the sun’s light having faded a couple hours prior to the near-fling, it was still just a tad earlier than Spike was used to turning in. “Now, I understand if you want to end what we were doing, but there’s minimal chance of us being caught now, thanks to Dinky being upstairs and hopefully in bed by now.”

She led him into her bedroom, and he was almost surprised to see it wasn’t some cougar’s sex dungeon, but the functional, cozy sleeping space of a single mother. The bed was large enough to dominate most of the room, old enough for Derpy to have had it since she moved into the house. The blankets were ruffled all over, making it entirely impossible to guess which side the mailmare slept on; before he could try to get some idea of where he could sleep, Derpy plopped down on the side farthest to the door. She stretched out and yawned before slipping under the covers. “If you want, we can swap sides.”

“Oh, no, it’s fine,” he replied, stripping down to his boxers. Any arousal he’d suffered from earlier had been ended when Dinky interrupted things, and with Derpy’s back turned to him, he felt nothing but the utmost confidence in climbing in bed. Thoroughly exhausted from the day’s odd events, Spike barely had the energy to keep his eyes open. He was out nearly as soon as Derpy cut the lights.

_-_-_-_-_

While Spike had fallen asleep, Derpy was restless. A quick peek at the clock revealed that what had felt like ten minutes had actually been nearly three hours, and yet even as she had been awake for the entire time, she hadn’t grown bored. That damned heat still creeped through her, ruining any chance she felt she had of putting the encounter on the couch behind her. Whatever it was about Spike that kept her from being in her rational mind still affected her while the dragon slept, so it could not have been something he was consciously aware of; no spell or magic was causing her arousal. She couldn’t just jump him, despite the earlier enthusiasm he had, not while he wasn’t fully aware of what was happening; she may have felt a bit odd about the entire situation based on Spike’s age, but she wasn’t about to force herself on a defenseless colt.

She turned her head to look at Spike, to make sure he was still asleep, and found her assumptions to be correct. She had to be careful not to wake him as she rolled over to keep the dragon in sight; she made sure her body faced him so she could stop as soon as he woke, if she wasn’t done by then, or something startled him awake. The entire time, she was furiously embarrassed to be doing something with a teenager nearly half her age lying next to her, even as she snuck a hand under her panties. She shut her eyes as her fingers grazed her lips.

Derpy recalled the pattern she always used, and relaxed as her fingers went to work. Her hand rubbed at her labia in a teasing caress, drawing some of the heat in her stomach down as the neglected flesh sparked to life. The mailmare pressed her palm against her pussy, grinding against it as silently as she could, careful to keep the bedsprings from squeaking too loudly. She slipped a finger in and swirled it around her walls; after years of minimal stimulation, the velvet flesh clamped down on her digit like a vice. She worked at her cunny as calmly as she could, careful not to make too much noise; it didn’t help that she could feel a gasp rising through her throat. Frustrated, she grit her teeth as a little gasp escaped her lips.

She looked at Spike, making sure he was still firmly asleep, as she reached for the hem of her top; when she confirmed her was indeed still sleeping like a log, she lifted the thin nightshirt, freeing her hefty breasts from their cloth confines. Derpy wadded the shirttail into a makeshift gag and clenched it between her teeth to muffle any noise she might make. Her free hand grabbed a tits, massaging the sensitive orb as her other paw worked her soaking twat. She moaned into the shirt, free of some of her inhibitions; the mailmare pulled a finger from tunnel and played with her clit, running her moan into a barely contained yelp. She pinched her nipple and bucked her hips against her hand with wreckless abandon.

While she first stared at Spike to make sure he stayed asleep, now her thoughts took a turn for the obscene. She plunged two fingers in as she imagined the dragon holding her hips as he pumped into her, and her overactive imagination began to take hold; even though she wasn’t that friendly with them, Derpy had heard of what happened between the diamond dogs and Rarity, and how the young dragon next to her had led the charge to her rescue. In Derpy’s mind, she took the place of Rarity…

Taken from her home, the mare was shackled and shoved down a hole; her captors were bigger than her, and demanded that she mined for them. At first she refused, but one got rough with her, and she cooperated only for her continued safety. She knew those above ground would look for her, that they simply had to. Her salvation came in only a few days, heralded by the sound of fighting up the tunnels; the scuffling got louder as the last few fleeing creatures slammed a large wooden door shut onto the tunnel. Whoever was one the other side was strong, and tossed a dog through the reinforced gate.

A portcullis dropped just as the invader stepped through the door, separating him from the prison cells as several dogs emerged from side tunnels. Derpy averted her eyes as the scene unfolded, unwilling to watch her rescuer fall. It wasn’t until she heard the portcullis slammed open that she realized hope may yet be a possibility. For a moment, the shape of an angry dragon made her jump, but she remained firmly chained to the wall and unable to escape.

Standing to his full height, Derpy recognised the form of Spike, the local librarian's assistant, one of the kindest creatures anypony could ever meet; yet here he was, crushing, pounding, and slamming diamond dogs into walls as if they were sacks of flour. She squeezed as close to the wall as she could, watching in awe as the dragon grabbed the bars in his claws. With a strained grunt, he tore the metal door free of its hinges, and slowly walked towards Derpy. She gasped in surprise as his claws broke through her shackles, barely finding the time to stretch her sore limbs when he spoke. “Are you okay?”

Looking past him, Derpy realized that the only reason he had come into the mines was to rescue her, and she threw her arms around his neck and pulled herself closer. She stood as tall as she could to kiss him, more than happy to be saved from such a dismal fate. Slipping an arm around her back and one under her knees, Spike stood straight and carefully stepped over the fallen bodies as he carried the mare to the surface. Once out of the mines and the quarry, Spike set Derpy down on the grass under the shade of a large tree, and began to check her for wounds. She stopped him by placing a wing over his snout. “Thank you, Sir Spike. You have earned my gratitude.”

She rolled him over so that he was on his back and straddled his codpiece; his large claws took hold of her hips and squeezed tightly, massaging the firm flesh under his sure grip. She went to press down into a passionate kiss, but failed as her hands drifted over his chest and dug into his ribs, causing the gallant drake to snort in laughter...

Derpy broke from her fantasy as Spike snorted next to her; her concentration was broken, her approaching orgasm cut off before it could cool her desires. Wishing to avoid the dragon's attention, the mailmare dove under the covers and hid in hone darkness beneath the sheets. It was only as her heart slowed down, her nerves calmed by the lack of activity, that she realized how much of a mess she'd made of herself. Her panties were soaked through, and the fur of her thighs was slicked down; she could even smell it on the sheets. She was mortified, even as she stripped herself of the wet cloth for some measure of comfort against the nagging moisture.

Derpy took off her shirt to dry herself, sure she could sneak from her bed and grab a change of clothes, then head to Sparkler's room for the night. The plan would have worked if not for the lingering scent she would have on her, and the sheets, leaving her entirely out of options. It took her longer than she liked to admit to realize that Spike was still very much asleep, and may not notice the smell when he woke. Derpy looked into the darkness, naked and smelling of her own sexual frustration, as her eyes adjusted enough to allow her some semblance of sight. Spike's tail lay limp, twitching slightly as he dreamed, proving to be as flexible as the mailmare had first thought.

Unbidden, Derpy's eyes drifted up the dragon's body, drinking in his scaled, muscled form so common of the dragons of myth. Some part of her was excited to see he so closely resembled the warrior of her fantasy, and that part still had some measure of hold over her actions. As she stared, studying every inch of the drake's physique, her eyes rested in his boxers, tented as his cock stood erect beneath the sheer fabric. Her conscious screamed at her to stop even as she pulled his underclothes down. Her breath hitched in her throat as she caught sight of Spike's stallionhood.

Unlike a stallion, the dragon's dick had a pointed head, surrounded by a ring of soft, knobby barbs; Derpy's heart jumped in her chest as she touched one of them, and it pulsed at the sensation. The knobs continued down his shaft, more like firm bumps than anything, until the drake's cock smoothed out just before it met a slit in his groin. The mailmare wondered how such a tool would feel inside, and the very idea of taking such an alien cock shot a fresh wave of arousal down her spine, even as she worried what those spines might do to her. The rational part of her mind thought the odd penis was nothing more than a curiosity; the horny part of her mind couldn’t get past all the wonderful sensation those knobs promised, even as it twitched and pulsed with every beat of Spike’s heart.

The oddest scent was in the air; a delightful perfume of musk seemed to hang in the air underneath the covers. Derpy knew precisely where the scent originated, and she could hardly resist the temptation of leaning in for a better sample. Spike’s cock was covered in a thin sheen of fluids from the slit below, which she imagined was similar to a stallion’s sheath; the smell, that pleasant odor that tickled her nose and sent shivers down her spine, had to be coming from that strange, curious orifice. Against her better judgment, she traced her tongue over the gash’s lips, pressing in as she went; it had surprised depth, and by the time her cheek was against the dragon’s cock, her entire tongue was buried in the hole.

The juices inside tasted liked spiced seawater, and burned her tongue with a taste that seemed to coat every inch of her mouth. Derpy closed her eyes and braced her arms on either side of Spike’s hips to better explore the unusual pussy. She had only done anything like this once, and that was years ago, but despite her clumsiness, her probing tongue seemed to be doing a fine job, judging by the amount of pre Spike’s cock was leaking. She froze as the young dragon stirred.

Moving from deep sleep to just dozing, Spike slowly became aware of the current state of body. and he panicked slightly as the thought of the admittedly attractive mare next to him rolling over and discovering his arousal. A new sensation shot through his body from the slit where his cock protruded; he turned his head to the side, eyes going wide as saw the space next to him was empty, wider still when he looked down and saw the lump between his legs. He didn’t know what to think about this, or even if his situation was actually happening, and not some dream. Grabbing the covers, Spike threw them from the bed. He wasn’t quite sure how to react when he saw Derpy’s naked body, and was even more confused when he saw her tongue wriggling in his slit. His eyes locked with hers as she slowly lifted her head back, her mouth opening and sealing her lips around his shaft.

Noticing the dragon’s confusion, the mailmare swallowed his entire cock, before slowly pulling off; she trailed her tongue on the underside of his dick as she let him out with a pop. “Want me to stop, Spike?” she asked, teasing a finger into his slit as she spoke. The drake stuttered for a moment before quickly shaking his head; this was his first sexual experience, and though it was entirely unexpected, he wasn't about to end it so quickly. Nodding, Derpy closed her eyes and teased her tongue around his crown. She pursed her lips and blew over his dick, using the sudden change in temperature to keep the dragon fully excited.

As slowly as she had pulled away, the mailmare took Spike back into her mouth, taking her time to massage the organ as it inched into her throat. The young drake clutched the sheets in his claws as the sensation jumped through him; it was all he could do to resist the urge to buck his hips. He groaned as Derpy started bobbing her head, easing most of his dick in and out to avoid setting him off too soon. However, those efforts were wasted the moment her tongue slid between the spines of his crown; Spike grunted as his body tensed, barely managing to groan out, "D-Derpy."

The pegasus's eyes widened as the strange cock in her mouth pulsed, flaring it's odd frills in some vain attempt to find purchase to better deposit its load. The first burst of cum splattered across her tongue, sending shivers down her spine as the spicy flavor reminded her of the musk that tempted her in the first place. The mailmare moaned as the next rope joined the first, pooling in her mouth as she held onto the taste as long as she could. Each shot, she caught in her mouth, not swallowing until she was sure Spike was done; it was an impressive mouthful, enough to force her cheeks to bulge if she kept the dragon's tool inside.

Spike looked down at her with wide eyes, half-dazed in his post-orgasm delirium. Part of his mind realized this was usually the part where he woke up, but as he saw Derpy pull off, her mouth still full of his seed, he realized this had not been a dream. The mailmare swallowed as the drake's throbbing organ began to slide back into it’s protective slit; she had to be careful to open her jaws as wide as she could to keep his spines from catching on her teeth. She sat up, eyes locked Spike as best she could managed, unsure why he just stared at her, blankly looking as though he felt no emotions in particular. She’d taken things too far, and she knew it; there was no other explanation for the dragon’s lack of expression.

As she moved to leave, hoping Spike wouldn’t be too angry, a firm tug on her arm sent her tumbling back onto the bed. Derpy felt the rough skin of the dragon's palms through her fur as has held her arms to the comforter, keeping her from making the same mistake of judgment she’d made mere moments before. A pair of lukewarm lips crashed against hers as the drake crawled over her; the mailmare didn’t hesitate in pressing back, glad for the attention paid to her. She wiggled as Spike’s tail wrapped around one of her legs and attempted to press against the dragon’s fire-heated body.

What the dragon lacked in ability, he made up for in enthusiasm; he let go of Derpy’s arms, placing one claw under her upper back and another on her hip. In kind, she dragged a finger over the scales of his chest, using her other to snake to his groin and tease his cock from its slit. Spike broke the kiss and groaned, moving his hips against the mailmare's hand as his crown peeked out, smearing pre over the dancing fingers that sent shivers up his spine. “Hold up,” Derpy said, and as if somepony threw a switch, the dragon pulled away. “I didn’t say no, just for you to wait while I grab something,” she explained as she crawled over to the nightstand.

She pulled open the drawer and rummaged around for a moment, before holding out a bright purple package; Spike recognized a condom when he saw one, though the brand was one he had never seen until then. “Now, ponies and dragons are pretty different, but I don’t want to take any risks,” she said, pursing her lips to look cute, as if the dragon needed any persuasion.

“Oh, of course,” he replied, reaching for the plastic little pack. The pegasus held up a finger to stop him, before pushing him back.

“I’m a little worried your claws will tear it.” She tore the wrapper open and showed him the latex sheath; it shined with a little pre-packaged lube, but was otherwise bland and entirely uninteresting. “Now, lie back and let me take care of it.” The dragon obeyed, leaning back until Derpy had a perfectly clear view of his fully-emerged cock. She ran a finger up his shaft, sending a shiver down his spine as she leaned in. “Now, it’s been a while since I've done this, so bear with me, okay?”

She rolled the first bit of latex over the dragon crown with nimble ease, grinning as the drake pushed against her fingers, like his body was trying to help Derpy encase his spine-covered pride. Spike winced a bit as the condom moved over the ring surrounding his pointed tip, pressing the spines of his cock against his shaft with surprising ease; reflexively, he flexed, forcing the compressed barbs to widen out, ballooning the latex and only adding to the uncomfortable pressure. He wasn’t too fond of the condom, but a deeply-ingrained part of him told him to shut up and roll with it if it meant having sex.

Derpy wrapped her arms around Spike’s neck and dragged him down with her as she fell on her back; the drake kissed down her jawline and onto her neck. His instincts told him the neck was a soft spot, and the aching in his mouth could only be related, so he nibbled at her skin and sucked on the sensitized little bites. The mailmare moaned and pulled him closer, the fire in her belly stoking hotter and hotter with every little nip, every minute motion of the dragon’s tongue. She felt his crown bump against her lips, rubbing against her plush labia with every beat of Spike’s heart

Tensing her arms just a little bit more, Derpy slowly and purposefully moved one leg at a time, spreading her thighs wide and forcing the drake’s cock against her until his tip slipped into her velvety passage. She took a few deep breaths and then squeezed her leg muscles, crashing Spike’s hips against her own as he plunged completely; he was breathless, amazed at how every muscle contracted around him at the mailmare’s body simultaneously fought against his intrusion and welcomed him with open arms. Once he got used to the pressure on his cock, Spike looked down at Derpy; she had her eyes shut and squirmed against him, a dopey smile on her face.

Tentatively, he started thrusting, testing what motions felt the best. The pegasus whimpered and rocked her hips; Spike had the right amount of girth and texture to hit everywhere he needed to stoke the fire in her belly. Taking her enthusiasm for approval, the dragon pumped harder; the only thing stopping him from fully enjoying things was the odd angle he was in. He was unsure if he should brace himself on his arms, or grab Derpy’s hips for leverage while simply laying on her; neither option seemed ideal, as he did not want to discomfort the pegasus with his weight nor miss any better angles. For the time being, he made do.

Derpy didn’t mind the awkwardness of Spike’s first strokes, instead reveling in having a partner for the first time in far too long. She matched his every move, slapping her hips against his as fast as she could; hoping to at least help him, and instead killed the momentum. Above her, Spike growled in frustration, and the mailmare feared he’d been discouraged or too agitated to continue; it wasn’t until she felt his tails wrap around her waist that she realized how wrong she was. The dragon’s demeanor shifted almost immediately from the methodological motions of a novice, to the rough pounding of a sex-starved animal. He pulled her up and slammed down hard enough to bang the headboard against the wall, all thought or worry for others in the house gone in favor of the moment.

Derpy’s eyes completely lost focus as she lost herself, gasping at each deep thrust; the dragon’s cock was long enough to just barely kiss her cervix, keeping a painful possibility completely pleasurable. She shouted as he gained speed, clutching at the bedsheets for fear she’d come loose and miss even a tiny portion of this. She loved the rough pounding, the animalistic dragon above her grunting and growling with exertion as his tail held her hips; she didn’t even care when she felt a bit of fluid spurt into her, a sure sign Spike’s crown had torn the condom. She could have told him to stop, but she really couldn’t care less if he came in her; the possibility only turned her on more, wrapping her legs around Spike’s hips to prevent him from pulling out.

Derpy could feel Spike’s spines puffing up inside her; every thunderbolt they sent crashing through her only signalled the dragon’s approaching climax. She pulled his head down for a kiss, only for him to dive farther down, and latch onto her neck again; he didn’t nibble or suck, and instead held a mouthful of her skin in his teeth as he picked up his pace. Primal fear, pleasure, and a little pain combined in the mailmare’s head, leaving her on the knife’s edge between bliss and panic, only set off by the drake final, heavy thrust. She saw stars as the dragon’s spikes flared out inside her, and nearly had a heart attack when the first spurt of his seed shot into her. It was hot, thick, and Spike had plenty more where the first bit came from.

Derpy whimpered as she came again and again, sure that there was something in the dragon’s cum that had such an effect on their mates. She was packed completely full with sticky, wet heat that radiated out, and she loved every second of it; even if she could feel her legs, she wouldn’t have released her grip. Spike slowly relaxed his hold on her neck before gently lowering Derpy back to the bed; he took his time in pulling out, every sense of his telling him to stay firmly inside his partner, and with good reason. He spasmed as he tried to free himself, his sensitive nubs leaving him too stunned to move without overpowering his senses. Below him, Derpy giggled.

“Go ahead and sleep, I’ve got a couple pillows right here,” she said in a tired, euphoric voice. For once, her eyes were in what most ponies considered a normal position, and not for her trying; her every muscle was too relaxed to bother twitching out of place. Hesitantly, Spike placed his head on one of the mailmare’s breasts, and a sweaty, satisfied pile of dragon-pony relations slowly drifted off to sleep.

_-_-_-_-_

Spike woke first the next morning, and half wondered if the previous night had really happened or if he’d simply dreamed the entire experience; the bare warmth against him and his own nakedness told him otherwise. Derpy slept peacefully, uncaring that the sun flooded in through the window. Like Spike, her upper body was exposed, and despite the obvious thoughts with her generous breasts free for him to see, nothing sexual crossed his mind; the way the sunlight turned her grey fur a golden hue made her appear angelic, like she was so far above such temptations. Despite the warmth of the room, exaggerated by the mugginess from the previous night’s storm, the mailmare shivered and cuddled up to the drake. Slowly, one of her yellow eyes opened, and met his gaze.

“I just may have to take Twilight up on her offer if I get to see more of you,” she said with a sleepy smile. Derpy rolled onto her stomach and stretched an arm over the dragon’s chest. She fiddled with the nightstand before tossing the shedded condom and its wrapper into the small trashcan she kept by her bed. The latex barely left her hand before the bedroom door opened and a magenta mare popped her head through the crack. The newcomer was a unicorn that Spike had seen with Dinky on a number of occasions, though they were never introduced; he figured she was either Dinky’s older sister or babysitter.

“Mom?” the younger mare asked quietly, as if unsure of what she was seeing. Derpy looked at her eldest daughter and yawned a bit, before blinking her eyes straight. “Uh, good morning?”

“Morning, honey,” Derpy sleepily replied, shifting until she lay entirely over Spike’s abdomen; the mailmare propped herself on her elbows as spoke. “You just get in?”

“Oh, no; I got home about an hour ago,” Sparkler answered, looking between her mother and the dragon she had pinned beneath her. The unicorn seemed a bit uneasy seeing such a sight, given that her mother hadn’t been involved in any behavior like this in her entire memory, or, at least to her knowledge. “Listen, I have breakfast cooked up, so just come out and eat when you get ready, okay?”

“Sure thing, sweetie; Dinky up and about yet?” the pegasus asked, combing her mane with a hand as best she could. Sparkler only nodded her head as she slowly closed the door, leaving the mare and dragon alone for an indeterminate amount of time. Derpy sat up and stretched her wings out, yawning for what must have been the dozenth time that morning. She snuggled up on Spike’s chest, burying her face into his neck as she ran a finger down the drake’s jaw. “Now, why don’t you tell me what Cheerilee hinted at yesterday?”

The Bad Teacher

Cheerilee stood in Twilight’s upstairs bathroom, looking over the bottles she’d been given. Each bottle contained vitamin supplements more in line with an expectant mother than a health nut; the princess allowed no chance at any offspring the experiment resulted in to be of anything less than perfect health. The schoolmarm looked at herself in the mirror, nude from the waist up as she posed; she imagined herself with a swollen, pregnant belly and pondered for a moment. “Hmm, heftier breasts, thicker thighs, bigger ass… yeah, I could pull off the MILF look,” she said to herself, already certain that she was very, very fuckable; sure, she had a bit of pudge here and there, but a number of ponies said that was a plus. Many of those ponies were also the ones who had seen her kinkier side and certainly did not mind seeing her in a leather corset.

“I wonder if my gear will go in the lab,” she pondered, slowly dressing herself once more. Certain items were of high enough quality to warrant medical-grade storage and care, but the vast majority were entirely inappropriate for such an environment. Still, she’d be spending much of her time in the library, if not the lab itself, so she’d like to have her creature comforts; she had doubts about what she was doing, and if nothing else, having her usual toys would be a taste of regular life until all the strangeness leveled off. “I’m sure I can convince Twilight to let me.”

Her thoughts turned to the purple princess. Twilight, as enthusiastic as she had been, was not used to her new equipment; all she needed was a little motivation and she could turn the tables on the teacher. It was not often a unicorn used his or her magic to pin her down and rut her like a bitch in heat, but she rather liked it when it happened; the very thought of a repeat performance was enough to turn her on. She was being paid to do what she loved, and with no need for condoms or annoying birth control methods, she loved it even more; the fact the entire object of the sex was to get pregnant was a twist on a common fetish numerous mares had, and being stuffed with another mare’s foal added another tone to the kinkiness of the entire situation. She grinned as a familiar warmth bubbled inside her, an itch a certain princess would be all too eager to scratch.

With a devious glint in her eyes, Cheerilee walked downstairs, seeing no need to sneak. Twilight was in the kitchen trying, and failing, to make something other than chopped fruit for breakfast; she wore her usual combination of a blouse and slacks, protected from the mess she was making by an apron that was unfortunately covered in what could generously be called batter. The alicorn sighed and set the mixing bowl back down, drooping her wings in defeat as she puzzled over the mixture; it was then the cerise mare pounced.

“Hey!” Twilight yelped, entirely surprised by the hands squeezing her ass and shaft through her pants. Her words morphed into a squeak as she was bitten on the ass, gently enough to be more enjoyable than anything. She jumped and looked down, immediately recognizing the hand massaging her cock. “Cheerilee,” she groaned, hardening under the teachers ministrations; the groping hands and nibbling teeth didn’t stop, instead growing rougher as she responded. “I’m trying to make breakfast here.”

“I’d prefer something else, princess,” Cheerilee purred, unlatching from Twilight’s perky rear. In a flash, she’d undone the knot holding the apron in place and popped the alicorn’s trousers open; her breath hitched in her throat as she pulled them down, exposing a rather attractive area of Twilight's body. "As much as I love looking at you from behind, I want you turned around." The schoolmarm did not allow for choice, grabbing her prey’s hips and swinging them around; in an expert show of marksmareship, she caught the princess’s stallionhood, pursing her lips around its head as she looked into its owner’s eyes.

“I’m not complaining,” the princess murmured. Cheerilee was an expert at all things sexy, and the way she swirled her tongue around Twilight’s cockhead only reinforced the idea. She leaned back and allowed the cerise mare to work her magic, biting her lip as the teacher suckled on her tip; it wasn’t even a moment later that she was gasping every time Cheerilee swallowed her length. She rested her hands on the earth mare’s head, content to relax until she neared her peak. A devious thought entered her mind, something she struggled to resist. “Can, um, can you take me any deeper?” she asked, still unsure of how to use her endowment in its entirety.

Cheerilee only nodded before taking a deep breath, pausing only briefly to wink at Twilight before swallowing every inch of the princess’s cock. She flicked her tongue into the underside of the alicorn’s sheath and savored the sweet groans she heard; she was a pro at this, massaging the dick in her throat with muscles trained by years of experience. She choked a bit in surprise as once-resting hands gripped her head.

“I’m glad you don’t have a gag reflex, because I feel you’ve had this coming since you slipped out early yesterday.” Without hesitation, the princess pulled Cheerilee away; her horn lit up, sending tendrils of purple-pink magic to bind the teacher’s wrists and ankles. “Take a deep breath.” The earth mare did as instructed, more than a little aroused by Twilight's sudden change in attitude; without respite, the alicorn slammed Cheerilee’s face into her groin, forcing her cock as deep as it would go. The teacher was not sure what had possessed the princess to do this, but she decided it was not necessarily a bad thing; she winked at Twilight to let her know she wouldn’t do anything untoward, or at least anything that may result in unnecessary bodily harm. “I’ll try not to choke you; just shake your head if it gets to be too much.”

Cheerilee nodded as she was forced back, taking another deep breath just in time to keep from inhaling a large glob of precum. Drool spilled from the corners of her mouth as she was moved along the alicorn’s hard length, dripping from the well-polished member every time she was slammed back down. “Now I wonder,” Twilight began, twitching in Cheerilee’s throat. “Do I cum in your mouth, or over your face?” The princess puzzled over the quandary, ruthlessly fucking the earth mare’s face as she forced her orgasm near. She growled lustily as she reached the point of no return, her cockhead flaring inside the teacher’s tight throat. In the final instant, just before her release, she pulled back until only her flaring head was wedged inside. The edges of the princess’s vision went white as she came, muscles tensing as her dick twitched; Twilight gasped as her orgasm started, an unstoppable tide of endorphins flooded her body as she lovingly deposited her load in Cheerilee’s mouth, bulging out her cheeks and saved from spillage only by virtue of magic.

Time stretched on longer than it needed, turning seconds into a blissful haze as Twilight experienced her first orgasm while buried into something that wasn’t a cheap sex toy she ordered from a seedy catalogue. She whimpered as the teacher ran her tongue over her too-sensitive flare, feeling the reservoir of cum swish around before it disappeared down Cheerilee’s greedy throat. She regretted that her cock started deflating, regretted that she had to leave the warm confines she so loved right then; she gently patted the earth pony’s head and pulled out with a pop, still dribbling a bit of leftover semen as she flaccidly bobbed in the open air. “I really am glad you agreed to the contract, Cheerilee,”

“No thanks needed,” Cheerilee said, catching her breath. She was terribly aroused, arms and legs shaking as her pussy left a very noticeable mark in her panties, stuck fast against her plush lips as she trembled with the object of her desires inches from her face. “So, this means your going to knock me up, right?” she asked, voice barely a whisper as she imagined the feeling of hot cum exploding inside her. She enjoyed sex plenty, and had even engaged in some breeding roleplay with a stallion or two, even once in a threesome with Cloud Kicker where Cheerilee pretended to sell her off to some lout, but to actually offer herself up for the oldest and most basic function of life was just a bit exhilarating on a level she could not properly explain.

“If everything goes right, you’ll have a belly full of my foal as soon as you’re ready,” the princess said in the soothing, afterglow-tinged she always had after a good orgasm. “But, again, we have a couple of months until we’ll be skirting the date for conception if we want to be able to pay you.”

“Can… can we do it now?” Cheerilee wondered if she sounded as horny as she actually was, if the entirety of her needs were being fully conveyed. She looked up at the half-hard princess for her answer, only to see a slightly confused expression. For a brief moment, she was angry at the response; there she kneeled, wet enough to drown a fish, stomach full of warm cum, and Twilight had the nerve to keep standing there when she could have been fucking her senseless.

“Pardon?” the regent asked, cock bobbing in time with each syllable as the words sank in. It may have been the testosterone or some instinct that came with her new testicles, but something about Cheerilee asking to be impregnated stirred something primal within her; the fact it would be her foal only raised an odd taste in the back of her throat, like she was nervous, but so much sweeter. In the back of her mind, she tried to recall all the fertility spells she had learned, all the ones created to combat the very problem she was working against, until the one she wanted came to mind; it was old, old enough to have been made with the belief that mares determined the foal’s sex. Dark age of science or no, what the spell did ensure was that a healthy ovum was released, and like the powerful mage she was, Twilight cast it on her chosen partner without conscious effort.

Cheerilee, however aroused she was, knew the princess was getting hard again, her cock jerking with every heartbeat as it grew back to its full size. “I want you to fuck me,” the teacher huskily panted, wriggling in the magic bonds that still held her in place as she nearly soaked through the back of her skirt. “I want you to fuck me like wild animal.”

A growl rose through Twilight’s throat as she flinged Cheerilee onto her feet, still bound at her wrists and ankles, before throwing her onto the table. She certainly felt like an animal; she could practically smell Cheerilee’s pussy from where she was, and she hungered for it like a starving beast. The princess grabbed her prey’s shoulders and pinned her down while she poked and prodded around to find that delicious warmth that taunted her so. She rubbed her cockhead against a slick, wet patch but found no entry. With an angry grunt, she freed one hand to claw at the offending articles, tearing them away before leveling her flare with Cheerilee’s dripping lips. Without foreplay, without even a gentle nudge, she rammed herself as deeply as she could go.

The effect was instantaneous; the earth pony whimpered as she was split open, Twilight’s flared head wider than she expected, slick with cum and spit as it plunged into her depths. She twitched her hips against the invader, pressing back each time the alicorn thrusted, trying to bring her deeper than her delightful cock was; every bit of pre leaked into her felt like liquid fire as it burned a path to her cervix, where it puddled up and made her beg for more. The weight pressing down on her made it hard to breath properly, but it felt far too amazing to both resisting, so she squirmed and jerked like the good little slut she tried to be. Twilight hunched over her and buried her snout in her mane as she sped up.

“Yes! Cum inside me!” Cheerilee shouted, mustering all the breath she could. The alicorn above her growled and stopped moving, leaning over to rummage on the table for something while she kept the earth pony held down. Before she had a chance to complain, she was gagged, mouth stuffed with her own soaked panties as she felt the cock buried within her slowly shrink away from orgasm. She whined as best she could, but did not try to move her arms from their binds; it wasn’t her first time being punished in such a way, but she rather enjoyed being vocal. That familiar, almost comforting, snout buried itself in her mane again, inhaling her scent in a primal display of crude affection.

Twilight started back with the slow, careful patience of a burglar, easing in and out at a pace she knew Cheerilee would hate only for its gentleness. She clenched and wiggled around her, trying to entice aggression as the princesses worked herself back up; each measured movement teased the underside of her cock over Cheerilee’s g-spot with enough force to remind her precisely of what she was missing. Her control wore thin, eroding with every little noise Cheerilee made as she tried to piston herself over the princess’s rod; she herself could feel her own orgasm approaching, slowly, but with very firm knowledge of what awaited her, Twilight could hardly hold back. She rolled her hips forward, changing the angle of entry, and sped up just a bit, not showing the g-spot much attention but absolutely adoring every quivering muscle she rubbed against.

Cheerilee had asked to be fucked like an animal, and while that had been all well and good, but she was just a bit worried about hurting her; she never did enjoy being dominant, but that spur of the moment decision had been pleasurable, to put it mildly. “I hope you’re ready for it,” she whispered into Cheerilee’s ear, delighting in a hard thrust; the teacher moaned into her panties and nodded her head, laid flat against the table. The princess grit her teeth and gave up teasing, gripping her lover’s shoulders as she pounded away; bliss was just around the corner, just out of reach. Her pelvic muscles tightened as she neared her peek, shaft thickening and head flaring to drown the Cheerilee’s womb with her seed. Twilight's cock bumped against her cervix, and everything went white.

A gasp from the door broke her stupor; apparently Derpy had let herself into the library and walked in at either the best or worst of times. The alicorn looked at her, twitching as she unloaded inside Cheerilee, who was too out of it to bother with any greeting other than a bubbly mumble. “He-hey Derpy,” the princess squeaked out, embarrassed at being caught and still riding the high of her orgasm while she stewed in her own cum. With a wet popping, sucking sound, she pulled out, bringing a small flow of semen with her; it spattered on the floor and nopony paid it much mind. “I, uh, wasn’t expecting you to come back.”

“Spike gave me quite the sales pitch after I left,” the mailmare replied, fidgeting in place. “I’ll just wait in the foyer while you clean up, and then we can talk specifics.” She really did not want to discuss what she knew in front of Cheerilee, not after how she had acted. How was she supposed to know everything going on if the ad hadn’t specified.

“I’ll be right there,” the princess hastily said, using her magic to clean off her shaft while she buttoned her trousers. Twilight wondered why Derpy was back, given how angry Cheerilee said she had been the day before, but appreciated whatever Spike had done to make the mailmare see reason. She released Cheerilee’s bonds and stumbled into the front room with her dick half-out while removing spilled juices from her blouse. It was not an attractive sight, unless one enjoyed the sight or hermaphrodites slightly covered in their own fluids while reeking of sweat and sex.

“So...,” Derpy started, trailing off as she lost her words. She politely allowed Twilight to cover herself properly before continuing, surprised at how strange she felt actually seeing everything going on, even after Spike had tried to explain over breakfast that morning. “Spike came over yesterday afternoon and convinced me to come back,” she said, lying only about the time Spike had spent over. While perfectly legal, the experiment required Derpy to have avoided sexual contact for a period of weeks before the final interview, and as some internal bruising as a dirty set of sheets attested, Derpy Hooves had been a very bad mare in that regard. “So, you;re going to do to me what you've already done to Cheerilee?”

“Spike told you everything?” the princess asked, a bit worried somepony could have overheard them while at her house; while they had the princesses’ permissions and pardons laid out for them, the official actions that had to be taken would ruin the reputations of everypony involved.

“He stopped before the story got to the delivery room; I’ve been often enough to know what happens in those.” The joke was dry, but not untrue. Derpy leaned over and rested against a bookshelf, legs still a bit tired and certain parts were a bit sore, but not uncomfortably so. “So, we’re breaking the law for a good cause?”

“The very best!” the perky princess quipped, mustering a smile. “I know, I know, it seems like an odd solution, but I have my own hypotheses about what’s causing the sex gap,” she paused for a moment while the crude humor settled in, “and with the work I’m doing, not to discount Cheerilee and yourself by any means of course, we should have Equestria back on track to balanced numbers.”

“And the money? I have a family to feed as I’m sure you know.”

“Handled, fifty bits per day for the duration of pregnancy, and one hundred-fifty per week for childcare expenses afterwards, should you choose to raise him yourself.” Twilight honestly hoped the foals would be raised in town; she had grown rather attached to the idea of being a… parent over the days leading up to her true trials. The thought of a pair of bright-eyed rambunctious colts running around and calling her mommy made her tear up a bit, but she did her best to maintain royal decorum. “Oh, and all medical and prenatal expenses will be taken care of. You also should not worry about one of your foals getting sick or hurt, because I’ll be paying for that myself.”

“Sweetening the pot?” Derpy asked,looking unamused, but relieved that she could stop worrying about her family’s bills for the time being.

“Canterlot School of Business, graduated while I was still Princess Celestia’s student studying magic,” Twilight said with a smug smile. She knew every little thing she needed to do and say to keep a business running, and thankfully she understood enough about employee fringe benefits to know that she could cover nearly anything. “And don't say I’m crafty; I just care a lot for Equestria and her citizens, and this is a better way of helping everypony in the long run than fighting monsters ever was.” She crossed the room and stuck one hand out in confidence. “Is it safe to say you’re all aboard for this?”

“We still have some kinks to work out as far as actually making the foal goes,” the mailmare answered, shaking the offered hand firmly. After a brief moment, she looked down and grimaced. “That can wait until after you've cleaned up everything.”

“Right,” Twilight agreed, looking over herself once and turning to check the kitchen. “I think I’ll go shower... and grab a mop,” she groaned, hoping semen came out of hardwood floors without too much effort. “Just make yourself at home, check upstairs or the basement if you want, and if you need anything, don’t hesitate to ask Spike, if he’s even awake right now.”

“Sparkler’s the same way about getting up early,” the pegasus chuckled. “Go on and clean up, I’ll make myself comfy.”

_-_-_-_-_

Spike, in all his years of life, had never had to break into his own home, but as he tumbled through the basement window and fell onto a pile of old books, he came to the understanding that breaking and entering was not a career choice he should ever make. He rolled off the literature and walked around the display of sex toys and instruments he affectionately called the lab and made his ways upstairs. He kept an ear to the door for a while, listening for anypony who may be around; as far as he figured, Twilight thought he was asleep, and he planned on keeping it that way. He was going to follow his morning routine flawlessly before entering the library, albeit a bit later, but that was because today was a lazy day. He would speak to Derpy later; he needed to get into a shower before Twilight worried about him.

Author's Note

Right, gents, sorry for the delay, and apologies if this has not lived up to your expectations.
Consider it an early Christmas gift from me to all of you.
I haven't been anywhere near horny enough to write for this story lately, but I finished this chapter up in about a total of two weeks after getting back into the swing of writing again, so maybe, maybe I can update again with some sense of punctuality next time.

The Mop and Bucket

Spike found success in his sneaking; the upstairs shower was running and since he had not heard Twilight in the front room, she was likely inside. He creeped into his room and hastily changed out of yesterday’s clothes, stumbling onto his bed as he tried to pull his tail through his pants. He was not a master of hasty undressing, and did not benefit from an equine tail made of hair; he stopped his struggling when he heard Derpy laugh from the doorway. “Cleaner than Sparkler's room,” she said, smiling at him. She unbuttoned the collar of her blouse and fanned herself with a wing, but as much as Spike liked the sight, he knew better than to try anything. “I walked in on Twilight railing Cheerilee on your kitchen table.”

“Yeah, didn't expect them to go at it in the kitchen, soundproofing or not,” the dragon replied, still trying to wiggle from his jeans. He was oddly unaffected by embarrassment, even if the mare he’d lost his virginity to was standing in his doorway holding back laughter at his lack of coordination.

“Here, let me help you with that,” the mailmare giggled, striding over and plopping down next to him. She straddled his thighs for better access to his ass and the hole his tail slotted though; her fingers moved around the base of his tail and over the hem of his pants as she worked the frills under the denim, stripping him down as she went. She scooted them under her and allowed him to kick them off himself before raising up a bit and motioning for Spike to roll over. When he complied, Derpy sat herself back down on the spot she knew contained his genital slit, the obscene little gash her new favorite organ hid within; she ran one hand under his shirt leaned down, rubbing her snout against his. “And just like that, they’re off.”

The pair laughed quietly, mindful that the soundproofing did not apply to individual rooms on this floor. The mailmare relaxed and laid out over him, burying her nose into his neck and breathing in the last traces of sex that lingered on his scales. “I enjoyed last night,” she whispered, rubbing circles on Spike’s chest. “I hope that working with the princess won’t affect the odds of us having more nights like that.”

“You’re not supposed to have sex while participating,” Spike protested without thinking. The greedy, draconic part of his brain screamed at him in rage as he tried to take the words back. “I mean, it’s to prevent disease, not that I have any!” he added quickly, cursing himself for his loose tongue. “I’m clean, totally clean.” He smiled a sheepish smile and tried not to look stupid; he felt it was far too late to avoid that.

“Was I your first?” Derpy asked, blunt as a hammer. Spike tensed up underneath her and his breath hitched a bit. “You were probably the best virgin in the world last night, then. I’m not poking fun at you, either.” She meant every word of it, body still a bit sore from his actions; she probably had a little internal bruising from having her cervix pounded, but the lingering delight she felt every time she looked at Spike made it all so very worth it.

“Thanks,” Spike murmured in embarrassment even as he felt a stab of pride; it went without saying that Derpy was an absolutely gorgeous mare, putting even his childhood crush on Rarity to shame, and she was complimenting his abilities despite his complete lack of experience. Certain parts of him responded in kind, tenting his underclothes as it slipped under the hem of Derpy’s skirt as part of his brain said he should just take her again and damn the consequences. His claws wrapped around her hips and pulled her down, grinding his length against the welcoming slit he knew was only behind two thin layers of cloth, growl rising in his throat as the draconic parts of his mind briefly overtook the logical persona he always wore. A finger pressed against his lips stopped him in his tracks.

“Later,” Derpy whispered into his ear, reaching a hand under her skirt and pulling aside their respective garments. At once, Spike’s cock was pressed against her cunny, already slick with her own arousal. “Don’t thrust, just relax,” she teased, sinking onto him until he hilted, filling every bit of her. “We won’t have sex, but this feels nice.”

Spike was inclined to agree, the beast within sated by the contact; this was no carnal act of mating, but a connection between them that had no subtext and needed to go no further than they already had; in a moment, they had to part, and that was a terrible thing, but not so unbearable that they had to lose themselves. Derpy leaned over until she rested against the bed, breasts pressed against Spike’s face and straining under their confines. “Listen, Spike,” Derpy began, shifting over him as she found a comfortable spot. “You don’t mind me going through with this, right?”

Spike felt his stomach drop, hearing the unspoken question loud and clear; you won’t become a monster like your birthday a few years ago, right? had been what she meant. He himself was unsure if he could truthfully say he would not be jealous, as he very clearly remembered that greedy part of his mind he let loose the previous night; he was scared of himself, scared he would hurt somepony he cared about. “I understand you need this,” he said, settling for a middle ground; he could put Derpy and her family above his own desires.

“I’m being unfair, aren’t I?” She knew what it was like to have a partner run around on her; Dinky’s scumbag of a sperm donor had been cheating on Derpy for the latter half of their relationship, something she had known only for a month before she found out she was pregnant and the stallion subsequently disappeared. It was not a pleasant thing, being the only exclusive partner, and she imagined Spike would feel every bit as terrible as she had, even if both of them knew she needed the money provided. “I shouldn’t ask you to be okay with me sleeping with Twilight.”

“I get it,” Spike said, trying to sound reassuring, convincing, but he genuinely worried he could not keep his word.

“It’s not like I’ll only being sleeping with her, and after I’m confirmed pregnant, I’ll never have to again,” the mailmare said, pulling Spike close as she ran things through her mind. “You won’t mind me being pregnant, right?” She heard the dragon’s muffled reply, warm breath washing over her bust and his voice rumbled through her, soothing her worries a bit.

The shower’s constant white noise cut off, and just as they had when Dinky came near, Derpy and Spike separated with swiftness born of panic, leaving one partner cold and the other empty. The pegasus creeped downstairs and left Spike to care for himself. Cheerilee was still in the kitchen, freed of her magical bonds and walking about; the mailmare felt the need to apologize, but could not bring herself to do so, worried about lingering tensions even as the teacher picked up a pair of soiled panties and folded Twilight’s apron. She actually looked a bit worn out, clothes messy and mane unkempt, but that went with their new lines of work; a sarcastic smile wormed its way onto Derpy’s face as she realized she and Cheerilee had both worked for the Crown in some fashion previously, and their new jobs still fell under that category, if in a different light.

The door upstairs creaked open, breaking the soundproofing spell that had kept things so deathly silent. Spike walked down the flight, holding a laundry basket filled with business clothes and certain feminine articles, his face scrunched in barely contained laughter as he moved past Derpy, checking to see if anypony had visited the library today; it made perfect sense that it was empty, having not opened for business that morning with Twilight so preoccupied. “It’s safe to come down,” he called upstairs, voice breaking as he tried not to snigger. “I still can’t believe you held onto that thing!”

“It’s a good thing I have it because somepony forgot last night was their turn for laundry,” came the reply, quickly followed by a rhythmic clicking sound as Spike entered the kitchen and left Derpy alone in the foyer. “Please don’t be offended, Derpy; I’m not trying to be sexy or anything.”

For a moment, as the clicking drew nearer and nearer, Derpy Hooves wondered what in Equestria Twilight would need to specify she was not being sexy for, and having difficulty as the very purpose for which she had recruited the mailmare had been sexual, if not a bit scientific. Her thoughts came to a screeching halt as Twilight stepped into view; she actually gawked at what she saw, on eye going drifting away as though in defiance of what it had to see.

Princess Twilight Sparkle stood at the base of the stairs, clad in a black latex bodysuit straight from a cheesy spy film. It was a bit tighter than it needed to be, straining around her bust and bulging around her groin until the zipper’s teeth were exposed; her wings were forced through holes just a tad smaller than necessary, and the whole thing appeared to have been custom made for a mare just a bit shorter and thinner than Twilight currently was. The material was thin, glossy, designed with aerodynamics in mind the same way Wonderbolts uniforms were. Even in the warmth of summer, her nipples stood erect despite, or perhaps due to, the restriction and discomfort such a garment forced upon her. “It’s a long, boring story about why I have a sneaking suit.”

“Why the boots?” was all Derpy could bring herself to ask after a brief moment of silence. Against every purpose of a sneaking suit, even one made in such a skimpy way, it came with matching pair of laced boots that ended just below Twilight’s knees, made of the same black latex and discernible only by a change in how they shined around the edges; they ended in platformed stilettos, lending another six inches to her already regal height. The boots were also the only thing actually made to fit, it seemed; likely recent additions or blind luck on Twilight’s end.

“Rarity made them for me after she saw the suit,” the princess said as she ran a gloved hand down her side with a satisfying squeak. “I’m not sure why, though; I can barely walk in heels without breaking my ankles.”

“My oldest likes them, but I’m not a fan,” Derpy agreed. She smiled and let her mind wander a bit, snapping back to reality as a crash sounded from the kitchen.

“Twilight, you really couldn’t clean up in here?” Spike yelled out as he stumbled back into the foyer, shirt off and held at arm’s length; there was a noticeable wet mark that most certainly was not water. Twilight turned red and Derpy almost giggled at his plight. Cheerilee, however, openly laughed as she followed him out, stark naked and not holding her soiled clothes.

“At least you have spare shirts here,” the teacher said, motioning to herself. For once, she was not lecherous, and rather than make a show of herself she acted as though being nude was entirely normal; she may have had some credence in that nothing in the Golden Oaks Library was normal these days. She had also cleaned up as best she could without access to a proper bath and no stray bits of semen or vaginal fluids remained on her fur, much to Twilight’s unspoken relief; while she doubted it, a part of her mind always reminded her that somepony could look inside and see them, and at best it would appear as though she led some sort of sex club. “I put everything in the wash; not like I can walk around with cum stains on my blouse and skirt without turning heads.”

Twilight giggled and pressed her ears flat against her head as she tucked her wings in. “Sorry,” she murmured as her face turned even redder, awkward smile tugging her lips to break the tension only she felt.

“It’s alright,” the teacher chuckled. “It’s as much my fault as yours.” She put a hand on her hip pointed to the door. “I’ll go ahead and clean up while you two talk shop, if you don’t mind.”

“Floor swabbing going to be a rotating chore now or does that go with mopping?” Spike chimed in, voice intentionally nasally and dry. Cheerilee laughed and Derpy followed suit as Twilight blinked at him; that was perhaps the first time Spike had shown open acceptance of everything around him, let alone made a joke.

“Why don’t we talk about this downstairs?” Derpy asked, clapping a hand on Twilight’s latex-covered shoulder. In her gut, she was nervous, a bit nauseated, and little panicked at the idea of what she was going to agree to, especially after her last two forays into motherhood left her with only friends to help care for her foals. Legal documentation and blackmail material made it impossible for Twilight to toss her aside, and she doubted the idea even crossed her mind, but fears were fears.

“We can hold down the fort up here,” Spike said, nodding his head to the door that led downstairs; he displayed no hostility over things, much to Derpy’s relief, but she knew there was a conversation they had to finish soon.

“Go have fun while I mop up cum and Spike does whatever he does,” Cheerilee added with a wink at the two ponies in question. Twilight looked even more embarrassed, roused only when Derpy tugged her shoulder. She hesitated for a moment, but followed along, hobbling on her heels and using the mailmare as a crutch. “What do you do, anyway? Still the faithful assistant?”

“Well, until you came along, I was the one cleaning up semen.”

_-_-_-_-_-_

The lab was clinical, even with its carnal nature; metal tables lined the walls, covered by neatly ordered reports, observations, notes, and several other documents Derpy could not understand. In the room’s center stood three obstetrician examination chairs ringed by small wheeled tables with a complete set of tools necessary to probe a vagina; small metal boxes rested on their bottom shelves, unlocked and lids slightly ajar for ease of access.

“Please take a seat,” Twilight said as she grabbed two plastic folding chairs from a rack on one wall; jerking her arms, she unfolded them and slammed them down harder than she wished to, flinching at the impact. Slowly, she eased herself into the seat, latex bodysuit groaning under the strain as it stretched and tightened with her; her bust was squeezed tight and she had mild difficulty taking a deep breath, but otherwise she was comfortable. Derpy had no such issue plopping down onto the firm plastic, perhaps shifting once or twice to find a comfortable position, but otherwise had no issue crossing her legs and striking a businesslike pose.

The two sat in silence for a few brief moment as reality sank in and they each realized they had no earthly idea how to go about this. Were they both in agreement? What were the specifics they still needed to work out? Was Derpy going to opt for artificial insemination or was she wanting to go a more natural route? How would Twilight even initiate things, if she was going to initiate at all? It had been easy with Cheerilee, who was a horny mare just like Twilight was a horny mare, but Derpy was far from that; no steady partners in the past nine years, no rumors of secret rendezvous or friends with benefits. For all intents and purposes, Derpy Hooves was not the sort of mare who would agree to even consider participating in the experiment, let alone sit down in the lab and talk specifics. The princess glanced about the room in a bout of nervousness, taking in any small details she had available to distract her while she worked out the scenario in her mind; the boxes of specialty tools were open and ready for use if artificial insemination was on the table, and as she turned her gaze from one box to another, her eyes locked on something that she had not expected to see so soon.

A flash of pink from under Derpy’s crossed legs caught her attention; a little flower patterned onto an otherwise white, plain pair of panties sat on tantalizing display. It was not for a heartbeat that Twilight noticed the fabric was scrunched up and a little off center, pulled aside and stuck next to a grey furred thigh; a much more appealing sliver of pink was just next to it. Her lips were closed at the top and concealed her clit, but slowly opened the farther down her eyes went, until she had a perfect view of Derpy’s entrance; the pegasus was wetter than she would be normally, aroused either by thoughts running through her mind or the situation she found herself in. What would she feel like? Was she tight and constricting like a velvet-wrapped fist or delightfully accommodating, just begging for some rough treatment like Cheerilee?

There was an uncomfortable tightness in Twilight’s sheath as her cock tried to slip loose with no room to grow. A hand drifted towards the achy prick, intent on fixing its angle for maximum comfort; she stopped dead in her tracks when she realized nothing had been said in a few minutes and she had been staring for the majority of them. She looked up at Derpy and found her attention not entirely disliked, if unexpected. “I’m sorry,” the princess apologized for what felt like the tenth time today.

“No, it’s partly why I’m here, isn’t it?” she asked, uncrossing her legs and pressing her ears back against her head. “I’m just a bit surprised at…” she trailed off and waved a hand about in an all encompassing gesture. “I’ve never been with a mare before, much less a mare with a penis.” Her eyes trailed to the bulge in Twilight’s suit before climbing back up. “It’s not that you’re not attractive, but…”

“Oh, no offense taken,” Twilight laughed as she leaned forward. “Before this,” she began as she patted the bulge between her legs, “I only ever had eyes for stallions, well aside from a healthy appreciation for mares.”

“Glad to know I’m not the only one who’s had a bit of awkwardness here,” the mailmare sighed as she relaxed, thighs spreading as she sank into her seat. “But I’m sure you can empathize with the difference between saying a mare looks attractive and letting her stick a dick in you.”

“No less strange when you’re the mare with the cock,” agreed the princess. “I mean, I like the penis and everything that comes with it, especially the sex, but it has taken some getting used to.” She stopped for a moment and giggled. “The day I first got it, I did not know the urethra connected to my bladder since it was made just for sex, so you can get what happened when I sat down with it sheathed.”

“You didn’t!” the pegasus tittered.

“I did, all over my nightgown; it was not a fun time.” She still smiled as she recalled yelling obscenities as she jumped into the shower to minimize the mess. She spent three hours learning to unsheath at will but at least she had far fewer accidents now. “Speaking of this nuisance, do you mind?” she asked, running a finger down the zipper in front of her constrained cock.

“By all means, please make yourself comfortable,” Derpy replied, fanning herself with a wing. A normal refrigerator and a large, industrial freezer sat against a wall and pumped out warm air, making the entire lab a bit stuffy. “Don’t suppose there’s a thermostat down here?”

“Sadly not,” the princess groaned as she leaned forward and slipped a hand under herself; the latex mimicked her, squeaking and whining as it stretched. With a sigh of relief, Twilight pulled a second zipper forward until it rested just under her navel. Her half hard cock and balls flopped free and a look of tired satisfaction crept across her face. “I can’t let these get too hot,” she said, mimicking Derpy’s wing fanning. “Stupid suit holds heat like you wouldn’t believe.”

Twilight looked up at the grey mare and found she was otherwise occupied, eyes in focus and staring intently at the royal stallionhood before her. She looked a bit intrigued by it as it bobbed with the princess’s heartbeat, but there was little arousal on her end. Twilight, however, found the attention enjoyable, shaft hardening until it stood at its full, rigid length. “Already hard again,” Derpy said with a nervous giggle as undid she the first few buttons of her blouse, exposing a generous portion of her bust. “As much as I like seeing the effect I have on some ponies, and as much as I’m sure I’d enjoy having that inside me, I’m not sure I’m comfortable with it.” The mailmare looked a bit worried and shifted in her seat. “No offense to you or anything, and I still want to go through with this, but at least for now, actual intercourse doesn’t seem too terrible appealing.”

“I actually have things for just such an occasion!” Twilight said, voice giddy as she bounced to her feet, making certain parts of her anatomy wobble as she went. She walked over to a nearby rolling table and popped open a small trunk on the bottom rack before bending over to rummage through it. What little Derpy could see of the interior from behind Twilight’s perpetually wet cunny and swinging cock, the box was lined with velvet and contained a few individually wrapped packets, some of which she recognized as medical supplies. Twilight popped open one slim bag and dropped a sixty milliliter medicine syringe on the table and a small tube of what could be assumed to be lubricant. “I’ve had this bad boy for over two weeks,” she began, wrapping a hand around her shaft for emphasis, “but I’m still a mare, and I still own all the things I did before.”

Without further delay, she whipped out a long, orange rod that had clear tubing wrapped around it; it wobbled a bit as Twilight’s arm came to a stop, leaving no doubt Derpy’s mind as to what it was. “Derpy, meet Mandarin.”

The Mandarin Orange

Mandarin’s particular shade of orange was reminiscent of an overly bright toy one bought for young foals whose tastes were shaped solely by how visually appealing it was; Derpy found herself suppressing a chuckle as the heavy length of silicone bobbled in Twilight’s hand. “A friend from Canterlot got him for me as a gag gift when I turned sixteen,” the princess said with a hint of nostalgia. “Joke’s on Moondancer, though; he’s perfect for this.” She unrolled the clear plastic tubing until it hung at its full length before turning turning the shaft around to give Derpy a better look. “Eighteen inches long, double-headed for mutual penetration, with a nice tube running to both ends for injecting lube.”

“And how do you plan on getting your semen through that?” The mailmare really hoped the plan did not involve a catheter or funnel.

“Right,” Twilight began, snapping her fingers at the realization, “I keep forgetting that not everyone knows the previous attempts at solving our female-to-male ratio.” She twirled Mandarin around like a jiggly baton as she conducted an invisible orchestra. “Over the years we’ve learned that creating sperm and eggs is impossible; they’re completely genetically blank and useless as far as reproduction goes,” she continued as she walked over to one of the freezers. “Creation is impossible, hence my new testes, but aging is entirely possible, like the spell I used to make sure Cheerilee was ovulating.” Smiling the proud smile of a researcher seeing her labors blossom, she lifted the lid and sat a small rack on a nearby table. “With the right diet and hydration levels, plus a little magic to make sure I processed everything correctly, I managed to store up quite a bit, all viable.”

“With the dominatrix outfit, sex dungeon, and array of medical instruments I was guessing you had frozen semen in there,” Derpy said with a smile. “Well, that or a severed head, but I’m not a fan of basements anyway.” She was the first to admit she read too many trashy mystery novels, but perhaps trashy novels were not too bad. She grinned to herself and resolved to return Sparkler’s book when she got home. “Going to use magic to warm a sample and, ugh, squirt it in me?” she asked, shivering at how mechanical the entire process sounded when she put it that way.

“Nope, sperm are far too delicate for that; any sudden change in heat could kill them and render the sample nearly infertile,” Twilight explained, grabbing two glass tubes and setting the rest back in the freezer. “Gotta wait for these bad boys to warm on their own after I put them in this.” To explain what this was, she pulled out yet another sealed pouch, this time from the refrigerator; she tore the pouch open and poured its contents into a flask. The liquid inside was perhaps as thick as chilled syrup but entirely clear. “This is just a mixture of basic amino acids and sugars, plus a little zinc and some base neutralizers to maximize fertilization.”

“So, now we wait?” Derpy asked, leaning against a cabinet. Shaking her head, Twilight grabbed the flask and started walking back to the box that formerly contained Mandarin.

“Now, we need to prepare you, which involves magic and… stimulation,” the alicorn corrected. Seeing the cross look she got from Derpy, Twilight winced, but maintained her position. “The cervix dilates slightly during orgasm, so if you are nearing orgasm, I can bring you over the edge with Mandarin and finish fertilization.” She smiled a bit to ease the tension but still felt Derpy’s discomfort. “Just, um, lay back on the table and let me know when you’re close.”

The mailmare did as asked, stripping off her skirt and panties as she walked over to the gurney. Rubbing her fingers around her labia, she felt the leftover residue from her earlier relaxation with Spike; contact with open air revitalized whatever chemicals had made it so tingly, and with his fluids having filled every crevice she kept snug between her legs, pins and needles poked around her clit and she felt herself becoming aroused even as she laid down on the gurney. She pressed her middle finger against her hard button and wondered how Spike wasn’t constantly aroused if this was what his strange sheath was filled with, and how much she loved the way his ribbed, barbed shaft spread that pleasant burn through her body.

Twilight stood nearby, bodysuit unzipped while her cock stood at the ready and she nestled Mandarin between her breasts to warm it; in the back of her mind she was worried about cold silicone ruining the evening, but seeing Derpy playing with herself aroused a part of her Cheerilee had awoken before, that primal feeling that pulsed through her when she saw the teacher’s pussy bared for her to use as she saw fit. Now, with such a ripe, maternal figure lying before her, bringing herself to orgasm with her fingers as she waited for Twilight to cum as deep inside her as she could; she fumbled as she loaded the sperm packet into Mandarin’s special syringe, and nearly dropped the dildo itself when Derpy cast her a lewd, half-lidded glance. Carefully, she approached the gurney, worried she might break her word not to use her cock on the mailmare, as delightful as she seemed to be as she writhed in place and bucked against her hand with every grind against her clit.

The princess lubed the orange dildo up as quickly as she could, keeping one end dry to use as a handle for maximum leverage; Derpy was right with her, moving her hand away as Twilight rubbed the rubber cockhead against her slit, wincing only a small bit as the slightly chilled lube mixed with the fading stimulation she still received from her little dalliance with Spike upstairs. It was only a moment later she was split by the silicone dick and felt one of the princess’s gloved hands grip her thigh as she slowly pistoned the fake stallion into her pussy; being better than her fingers but not nearly as good as the real thing, Derpy still panted as she felt the shaft twist and squirm inside her, fighting her contracting muscles and ignoring her own movements. “Aim up a little bit,” she groaned out as she lost a perfect stroke when Twilight shifted a little to get a better angle. “Hitting my front is about the quickest way to get me off”

Knowing better than to discuss anatomy while fucking, Twilight compensated and moved to Derpy’s specifications, angling Mandarin to it bumped against the pegasus’s g-spot; she added a twist to the strokes for extra kick, delighting in the little noises her grey partner made whenever she found another nice trick. She felt a little neglected as she looked up at the mare she was pleasuring, meeting her gaze like a sober pony met a drunk’s; she felt good, big, bold as the mailmare looked at her, cheeks red in embarrassment at her first, strange time with a member of her own sex. Twilight planted a kiss on Derpy’s thigh and hoped she was enjoying herself; she nipped at the firm, sensitive flesh next to her, her own arousal driving her up the wall as she ached to do something other that kneel there work her arm like machine.

There was oh so much of her lab assistant to play with, from her firm, squeezable ass to her wide hips and large breasts; it was a true shame she couldn’t play with her like she did Cheerilee earlier, and hoped Derpy would come around eventually. For now, the alicorn delighted in surprising her new partner, nipping, licking, and sucking her way up those long, graceful legs to that tight, wet, tantalizing cunny that she kept hidden from the world. She bit a lipful of skin between Derpy’s thigh and labia and shivered at the moan she let out as a hand grabbed her mane and pulled her close. Twilight went from kneeling to squatting as she raised up and licked just above the pegasus’s clit, blowing a gust of breath over the juice-soaked fur and skin as she passed; even as Derpy gasped, the princess dove back down, sucking the little button between her lips and thrashing it with her tongue.

Her technique was an instant success as Derpy wrapped her legs around Twilight's head and squeezed. “Now, now!” she screamed out as she rushed to orgasm. “Squirt it!” The princess, despite her assistant's legs trying to burst her head like a melon, she had the syringe and spell at the ready. Timed as properly as she could, Twilight pressed the plunger and squirted her collected semen through her favorite toy and into her new playmate, getting about half of her own cum sprayed on her chest in a big, warm blob; with any measure of luck at all, her sperm would rush through Derpy’s dilated cervix and into an egg. The princess left Mandarin in place and gave the clit in her mouth another tender suckle, but otherwise remained motionless and allowed Derpy to unpack her own emotions over what had happened. They sat in silence in what must have been the most awkward position either of them could think of spending any amount of time in until the pegasus found her voice.

“The oral wasn’t part of the deal, but I’m not complaining,” she said, murmuring as her kegels twitched and pushed the dildo halfway out. She ran her hand through Twilight’s mane once more and patted her head. “Can I please get up? Silicone doesn’t feel half as nice when it isn’t doing anything.”

“Oh, right, sorry,” the orally-inclined alicorn mumbled out as she pulled away. She slipped as the heel of her stiletto failed to find purchase and fell on her back as Mandarin came loose; the orange cock bounced against her own and tumbled to the floor with a wet slap as lube, feminine juices, and cum met cold cement. With her dick standing straight up, her body sprawled out on the floor, and one foot wedged under the gurney, she very much appreciated Derpy’s helping hand in standing, albeit while the pegasus herself wobbled as she found her footing.

“Heh, sorry about the headlock,” the mailmare said with a friendly smile, golden eyes gleaming under the flourescent lights. “Though, that’s the best head I’ve ever gotten.” She almost sounded embarrassed to say it, but it was the truth. “Almost makes me wonder if all mares can get other mares off easily, like having a twat makes you better at handling one.”

“I wasn’t exactly thinking with that part of me,” Twilight chuckled as she motioned to her neglected shaft, twitching and drooling pre-cum as she went. “Now you’ve got me wondering if stallions are better at pleasing other stallions.” She laughed a little, pondering over an experiment she may have to try out in the future, after the dust of all this had settled and the colts were born if they were conceived at all. “Listen, Derpy,” she began, acting serious, “what we’ve done here is big, really big, and I’m sure you have a lot of fears and questions.”

“Oh, I’m sure it will all hit me after I’ve gotten a shower and gone home,” the mailmare agreed; her head was already in a bit of a fog, like after accidentally flying into a tree and trying to walk it off, body on autopilot while the brain spent time learning how to be a pony after a hard reboot. “A foal’s a big responsibility, and this isn't my first rodeo by any means, but I’m sure I’ll panic when I get settled in tonight.” She waved her hands about and sighed. “I mean, between walking in on you, a mare, sporting a cock and thoroughly giving it to my youngest daughter’s teacher and you then using a dildo to squirt your own semen into me after magically making sure I was ovulating could really put a damper on sanity.”

“You’re more than free to reconsider this all, no questions asked, if you want,” the princess affirmed, changing posture to look as unimposing as her tall frame allowed. “That’s assuming the sperm really are viable, so we won’t know for a few weeks at least.” The purple pony looked Derpy up and down and chuckled to herself. “I may well end up being a father, and will if this experiment goes well,” she started, laughing at the ludicrousness of it all. “A little colt might be calling me ‘daddy’ before I know it.”

Derpy shared in the laugh or a moment, before her thoughts finally moved back to what she had agreed to; she, a working single mother who had not had so much as a date since her youngest was born, was suddenly pregnant, with nopony in a small town knowing who the father was. It was almost scandalous, and were it not for the unknown father part, she might avoid the worst of the rumors. “So, this might be a little too late to ask, but what’s the cover for this whole thing?”

“Cover?” Twilight asked, not sure what the pegasus meant. “Cover for what?”

“Well, Cheerilee’s little adventures certainly aren’t unknown in town, with that odd club she likes to visit on weekends, but I’m otherwise unnoticeable and usually somewhat out of other ponies’ minds.” She motioned to her pelvis and tapped against the matted, wet fur there. “Now I’m suddenly pregnant with nopony seeing me out; no dates, hookups, or early morning walks of shame from my house or anypony else’s.” To her credit, Twilight looked rather surprised by what she heard; Derpy was hired on because she was god at taking notes in addition to her birthing history, and yet here she was pointing out an otherwise obvious flaw in security.

“Ponies do like asking questions,” she said, thinking back to tabloid after tabloid wondering why she went to Hayburger so often or wondering if she was romantically involved with somepony in secret, sneaking them into the library at night and putting them out before sunrise. “I’ll figure something out, just give me some time.” It would be difficult, but maybe she could ask the princesses for help making a convenient cover story. Perhaps she was providing counsel for a couple of expectant mothers at a hectic time in their lives, or working with them to discuss adoptions or other services they could take advantage of if the pressure became too much. “This is really something I should have thought of before we got this far.”

“Is it alright if I use your shower?” Derpy asked, deciding not to worry until she was in the comfort of her own home again; it was too much of a headache to agonize over every little detail all at once, which may have been why Twilight had neglected this facet of things, or perhaps it was simply too small a chink in her thin armor of secrecy. Paid breeding was a heavy crime, and even with crown approval they still faced their reputations being ruined, and poor DInky was having enough trouble in school with the other foals as it was. Sparkler was worldly enough to be fine, but the mailmare couldn’t bring herself to break her youngest child’s perfect image of her; her foals were the only reason she was doing this, to keep a roof over their heads and food on the table as best she could. “I need to scrub down before I head home.”

“Oh, that’s perfectly okay; if you need a change of clothes I’m sure Spike can find you something,” Twilight said as she turned away from the pegasus, dick whipping with her and knocking a tray off a rolling stand. The princess threw her head back and sighed; it was going to be one of those days again. “I’ll be up shortly after I clean up down here, and find a way to get this thing to go back down.” She finished by gently patting the top of her shaft; she was still rather painfully aroused from earlier, but now her mind was wandering too far too fast to do much of anything but worry over the details of what appeared to be a glaring hole in her defenses. “Oh, and before you go, do you mind doing one thing for me, just to try and keep things from looking too suspicious?”

“I was mostly kidding about needing a cover, Twilight, but go ahead.” Derpy stopped on the stairs and turned to the face the princess. It was difficult to take somepony wearing a latex catsuit seriously, especially when the front was completely unzipped and everything was on display for the whole of creation to see. Still, somehow Twilight made it work.

“Oh, sorry, nevermind,” the purple mare said with a small smile. “I was thinking having you talk with Cheerilee about Dinky’s classes around town, but it’s summer, so that doesn’t make much sense.” She waved both hands at the pegasus on the stairs. “Now, go enjoy your shower while I try not to knock anything else over down here.”

“I’m sure you’ll be a fine spymaster one day, princess,” Derpy chuckled as she finally ascended the stairs and returned to the ground floor.
