1940 - What Twilight Saw Outside

Author's Note

Be aware that the following story is rated M for Mature. Young children should not be here. Shoo. This is my only Mature fic on the site, so...

For background, this is a naughty offshoot of my Equestria - 1940 story situated in 1940 (duh) where Equestria is an island nation off the coast of the US about a third of the way to Europe, much like the Azores are on the other side of the Mid-Atlantic Ridge. As war sweeps over the European continent, a far darker force has begun to gather on the Equestrian lands, and Princess Celestia has sent for a specialist in friendship studies, a human named Jon Walthers. For it has been a thousand years since Nightmare Moon was banished, and the Summer Sun Festival is coming soon. Um. Approaching. Twilight is the one who... Look, I'll just let you read. If you're old enough.

The story is placed right after Prince Blueblood's auto accident (non-fatal, to many's regrets), and at that evening where Jon is getting an advanced lesson in batpony preening. While writing, I had to wonder "Just what did happen to Twilight Sparkle that night?" So I wrote it, as it would happen in a much more mature setting.

For reference, this timeframe is before Twilight Sparkle travels to Ponyville. And if you squint, you should be able to see Green Grass (from the Traveling Tutor series) picking up some spending money with a part-time job which has unexpected benefits.

1940 - What Twilight Saw Outside

Behind Green Mountain’s Door
Wednesday 19 June 1940

This day had been just as frustrating as the rest of Twilight Sparkle’s week. Worse, even. Ever since that human had arrived to upset her bookcart, she had been scrambling to restore Princess Celestia’s trust in herself, and worse, had been failing his unfair tests. In front of her! All of her studying, all of her brilliance, even spending all morning under Blueblood’s Cord roadster, putting together the engine until the motor car ran like a purring kitten had not helped.

In fact, the motorcar’s engine had tweaked her innards the way nothing had before. Twilight had never put together a gasoline engine until today, which had turned into an exercise of both mind and nose. Her own hormones were up, which made her extra sensitive to the way the mechanics Blueblood hired before had left their faint scents behind on every piece and part, from the way they sweated in the overheated carriage house to their excited whiffs of pheromones from working with such a powerful machine. Several psychology books Twilight had referenced drew parallels between motorcars and male phalluses, and the Cord had been a very powerful piece of machinery for her to manipulate under her stroking hooves and magic. The image had followed her around all morning, fading into the background when Blueblood and the human had their automobile accident, and reappearing in the back of her head when she looked at the broken roadster, like she had been responsible for un-masculinizing the prince.

Thankfully, the two of them, annoying pony and annoying person, had survived their accident with little more than bumps and bruises due to whoever had cast a cushioning charm at their impact site, but the crash still had given Twilight an overwhelming sense of guilt, which made her check the… masculine attributes of both of the victims before the municipal guard showed. Just in case. Blueblood’s member had been retracted into its sheath as proper, but the human just flopped out in front in a way that made Twilight quite glad he wore pants on a regular basis.

The mental image of that floppy phallus had amazing persistence in the back of her mind, lasting through her examination of the roadster wreckage, the brief report she wrote up for the police, and her trip back to the castle. She thought about visiting the hospital, but it would have been a waste of time because the doctors were taking care of her teacher, and the last thing they would need was a nosy unicorn in the room. Besides, he probably would have been stripped naked, and she was having enough trouble keeping from thinking about that dangling phallus due to the itching fire that had been growing hotter in her rear for the last few days, despite all her medication.

She had managed to put Spike to bed before going into the bathroom and trying to put out the fire, touching and rubbing in the ways she had used before but to no avail this time. She could get up the hill, but the crest evaded her whenever the human’s absence floated up in her head. He was supposed to be teaching her friendship, not biology, and the curiosity spasm she was having about his… equipment kept creeping into her thoughts.

Finally, she washed up and slipped out of her room, keeping a brisk trot down the castle corridors to Doctor Walther’s suite as she had thought about doing for days now. He was a doctor, after all, even if it was in Friendship Studies. A brisk evening of ‘friendship’ experimentation and exploration would settle her insides down quite well, particularly since he was a human, and as such would not be as hefty and overwhelming as a stallion pressing her down into the ground with his chest resting on her hips and wet phallus jamming up her vagina.

If everything went as planned, maybe she could even write a paper on this evening, under a pseudonym, of course. Then again, if he was already sleeping, all of the experiments would have to wait and Twilight would have to return to her room to finish the night in cold frustration. Or worse, if he regarded Twilight’s scientific curiosity about humans as some sort of aberrant perversion worthy of telling Princess Celestia about.

She would have to be subtle. She could do subtle.

Slowing her pace to a quiet walk, she approached the darkened guest quarter corridors where Doctor Walthers had been placed while a butterfly of nerves fluttered around in her chest. What if the reason for the human’s presence was to satiate Princess Celestia’s nighttime cravings, and Twilight was trying to steal him away? No, that was just silly speculation. Even though Twilight had heard many rumors about humans and their sexual experimentations, there had never been a human in Canterlot until now. Of course, there all the trips Celestia made to the other human kingdoms...

Twilight peered around a corner and regarded the suite doorway with a broad-shouldered pegasus guard standing in front of it. His stance was odd for a guard, with both ears flattened against his head and a distinct study of a nearby corridor ceiling instead of being alert for incoming danger. His blue eyes snapped down when Twilight Sparkle cautiously stepped out from behind her corner, then he glanced up and down the corridor as if he were looking for some sort of excuse before holding a hoof to his lips.

Twilight crept closer to the strangely behaving guard, trying not to make a single noise. His frantic ‘go away’ motions only drove her natural curiosity, and the sight of a book bag shoved into a corner behind him added exponentially to her craving for knowledge.

“Miss Sparkle,” hissed the guard in a faint whisper when she got close enough. “I don’t think you want… I mean Mister Walthers…”

A low moan wafted through the darkened corridor, a deep, heartfelt groan of pleasure that rose and fell in a suspiciously familiar rhythm, and came (literally) from behind the closed suite door.

“What was that?” she whispered back. “Is Doctor Walthers in trouble?”

A series of rapid panting noises broke the loud moans, then a sharp yelp of pleasure that drove sharp tremors down Twilight’s back until they lodged in her nether regions. She brushed past the guard and eased the door open, just a tiny crack at first, then a little more so she could get a better look at the inside of the suite and its contents.

It took a few moments for her eyes to get accustomed to the gloom, in particular since the ponies she wound up trying to see were already dark. Doctor Walthers was in the middle of two batpony mares, each of which had their wings extended for his ministrations. Oil glistened in the darkness as he gently ran fingers up and down the stretched membranes, touching here and rubbing there until both of the mares had flattened down on the rug and were uttering deep, passionate moans and groans.

He’s preening them. Both of them. At once. That’s four wings.

There seemed to be a competition between the writhing batponies to see which of them could get Doctor Walthers to rub or stroke their wings the most. One of them would stretch out on his lap, nudging the towel wrapped insecurly around his waist as she twitched and gave lazy flaps before the other would nudge her aside and push an oily wing up for his attention. Back and forth he went, with the mares grunting and moaning as if they were having intercourse instead of just getting their wings rubbed.

It excited Twilight in a way she had not expected.

There had been many late nights of studying in Celestia’s chambers while her teacher quietly went about the pegasus-like procedure of wing maintenance, the rustle and brushing noises making it very difficult for Twilight to concentrate on her books. Celestia did not use her own natural oils, of course. That would have scrambled Twilight’s mind and prevented any studying at all. Instead, she used one of the human’s brand of baby oil, applying it sparingly and only using her own nose and teeth to adjust the more troublesome feathers.

Twilight could still hear the pleasant sounds in the back of her head as the batponies smacked their lips or gave out little moans of joy, much more than Celestia enjoyed her preening time after a long day at court. It was beneath a student to offer her assistance to the Princess during the process, although Twilight had wished with all her heart that Celestia would have suggested it, or even just wordlessly floated over the bottle and given her a feathered wingtip to practice with. Worse, Twilight Sparkle could feel her own feminine parts begin to water at the scents drifting out from the darkened room. She wanted to slip inside, join the mutual preening, and lose herself in the feeling of noses and teeth rubbing up against delicate areas. Wings were such expressive limbs, filled with tempting tickling feathers in Celestia’s case or thin, warm membranes for the writhing batponies. Twilight was a unicorn, however, and as such did not have any kind of social grooming experience other than horn-polishing and kissing during dates.

At least I’ve helped polish a horn. A few years ago. I’m sure Moondancer’s recovered by now. It was only a small chip.

The pegasus stallion who had been standing guard certainly looked as if he wanted to join the preening-pile. He had intentionally been facing away when Twilight peered into the darkened room, but while she had stayed silent and watched, he slowly moved to peer over her shoulder until he was right next to her. In the wing department, he at least was much less intimidating than Princess Celestia. Or Cadence, who used a flavor of wing gloss which Twilight had no intention of ever tasting. In fact, the guard smelled… nice. A little like wintergreen, in fact, with the distinct papery scent of books and ink.

Ask to preen his wings. Go on. Just so you know how. It will be educational.

Muscles deep in her barrel clenched at the thought, sending waves of muscle spasms up and back until her nether regions locked up in a terrible itchy/scratchy/crampy way that would give her one barnstormer of a backache tomorrow if she did nothing to alleviate the blood engorging those particular organs. And worse, if she were to practice preening on this guard… that is get permission to practice preening on this guard, she was quite sure it would do nothing at all to relieve her sexual… that is perfectly ordinary urges. After all, watching a male human reduce two mares to mewing, begging, groaning puddles with his talented fingers had only made her own frustrated urges more manifest. Mostly manifesting in a puddle under her rear, if she was guessing right. Still, it would be an educational experience, and would distract her while waiting for the two batponies to finish their own preening and leave. Then she would have full access to the human’s… whatevers.

She eased the door closed (to the guard’s obvious disappointment), took a quick breath in the still air of the empty hallway, and asked the question before her nerve fled.

“May I preen your wings? Please,” whispered Twilight. “I promise to be careful and not do anything you don’t want me to do. If you don’t tell my brother, that is.”

“Really?” The guard blinked, then took several looks up and down the empty corridors as if he wanted to see if there was some sort of trap involved. Finally, he settled back down with a peculiar expression and lowered his voice even more. “No, I’m sorry. I can’t. I wish I could,” he added with a shy smile. “I’ve never had a beautiful young mare ask me that before, actually. Thank you.”

“Oh.” Twilight Sparkle considered the long walk back to her own room while trying to figure out what to say next. There was something about her own sweaty coat and the twitching muscles beneath that missed the guard’s cool breath against her neck, despite her expectations about what being breathed on would be. Without realizing it, that had changed a scant few minutes ago when they had been spying on the preening going on in the human’s room, much as if they had become co-conspirators in some naughty game.

The preening request had only been an impulse, done on the spur of the moment. Something boiling in her withers had moved into a much higher priority right now.

“Sir,” she whispered to the guard just barely over the sound of her breathing. Twilight took a step away from his dangerous scent and swallowed in order to continue without the erotic tickle in the back of her nose. “I need a room.”

“What?” All shyness gone, the guard nervously looked up and down the corridor again briefly and licked his lips. “I thought you had a room,” he whispered.

“Spike is in my room,” she hissed. “Since we can’t try preening, I need to take care of this—” she swished her damp tail “—or I’ll never make it back to my room without dribbling a trail. I need you to unlock one of the rooms in this wing so I can put out my fire and wash up. By myself,” she added quickly.

“All of the rooms are empty and unlocked,” whispered the guard, pointing with his nose at a nearby door. “That’s the biggest one. I’ll knock if anypony comes… If anypony else shows up.”

“Good.” Twilight Sparkle slipped into the room, a larger suite than the human’s for some reason, and turned a few of the overhead lights on so she could make sure it was empty. Then she darted into the bathroom and grabbed a towel while berating herself for not dragging the guard along with her.

If she had another unicorn around, there were spells to take care of this kind of problem, but they invariably required concentration, which went right out the window (sometimes literally) when used on one’s self. And the idea of buying a device to take care of her frustrated cramps, in a town where anypony she met might tell her parents about her purchase, had never appealed to her at all. The idea of using one of Celestia’s guards… had astonishing persistence in the back of her hormone-fogged mind. Particularly that one.

Focus. Guards guard. They’re not for that particular purpose. There’s probably something in their manual forbidding it, anyway.

Twilight sat down and tried to bring herself to climax as she had done many times before in a darkened bathroom, but this time she still could not put out the fire. She could touch herself all the way across the outside of her sensitive areas, but the sparks she generated fled her touch, slipping into her belly and tying her guts into macrame knots. After many minutes and much grinding of her teeth, she finally came to the conclusion that even her most practiced touching was not doing a whit of good, and there was no way in the world she had the willpower to cast more than a simple spell away from herself.

The deep, shuddering moans from next door did not help at all. It seemed excessive for just preening after all.

As an experiment, Twilight threw up a sound sphere, a simple spell that would not allow sound to escape her present vicinity, and although her horn spit sparks in all directions, it did work, and threw a faint blue sphere over the room that would remain in place for several hours. Flushed with her success in more ways than one, she then tried to cast a probing spell to calm the fire in her loins, and just barely managed to shut it down before something terrible happened.

That was it. There was only one usable option left.

She peeked back out into the hallway where the uncomfortable guard was at least trying to look like he was studying, even though he was holding his textbook upside-down. It was quite obvious that he was distracted by the moans and groans coming from behind the door he was guarding. Very distracted indeed, if the dark phallus jutting out from under his barrel was any indication.

Guards guard, Twilight. Stop looking at his junk. Besides, Shining’s was bigger that time you caught him getting out of the shower.

Twilight Sparkle most probably would have ducked back into the room if the guard had not looked up at that moment. His eyes were wide, his nostrils flared, and his ears perked-up, taking in her bedraggled appearance without comment although with a growing expression of honest concern.

“Can I help you, ma’am?” he whispered, sliding the textbook back into his bag as she walked down the hall toward him.

“I’m going to rut out… I mean root out Doctor Walthers’ guests,” she whispered back. “I need you to make sure we’re not disturbed, particularly by my brother.”

“So the two of you are going to be…” The guard trailed off, then got very serious and resumed his position to one side of the door. “Yes, ma’am,” he whispered. “None of my business, ma’am.”

Twilight Sparkle considered her entrance in the dim lighting of the corridor. Kicking down the door to Doctor Walthers’ room and flinging herself on his naked body was most probably the worst possible way of dealing with her hormonal situation, although it had the advantage of being the most direct and the fastest way to cure her infernal cramping. Tapping lightly at the door and waiting for somepony to answer it was just as much of a non-starter, because the sounds of moaning and groaning from inside the room had only grown louder while she had been down the hall. That left an approach somewhere between the two extremes, which would probably depend on just how tired the moaning batponies were…

After a moment of listening to the gasps and pants from inside the room, Twilight moved closer to the door. It sounded like only one of the batponies was enjoying her preening with unnatural enthusiasm, which probably meant their oily body-rubbing was nearing an end, and Twilight would be able to get her human alone-time very soon. Her mind was occupied with just how to match a human’s Tab A with a unicorn’s Slot B when she cracked the door open just a bit to look inside, so she did not really understand what she was seeing.

All that was visible of Doctor Walthers in the dim light was his bare feet, toes up.

He was lying on a thick rug with a batpony mare seated on his waist, her wings outstretched and both of them totally oblivious to Twilight’s observation. At first, she could not understand just why they were in that uncomfortable position on the floor, until the batpony mare began to rise up, ever so slowly, exposing the long pink shaft of the human’s phallus. Then when she reached the apex of her ascent, her knees gave out and she collapsed back down on the human, making his rigid phallus plunge inside her vagina again.

Up and down she went, with the human’s phallus vanishing and reappearing with every erratic thrust she made. Obviously it was being driven into the same area that Twilight was having such an issue with, although the batpony was not having nearly the same issue. The mare’s tail was curled to one side with the instinctive convolution of a female being mounted by a male, but in this case it was unneeded. Every time the mare bore down, she hunched over the intruding organ with a shuddering moan that sent ripples all up and down her back and made her broad dark wings stretch out in both directions and tremble, most likely an instinctive reaction from when pegasi used to mate in the sky.

The trembling mare let out a loud shriek as tremors locked her body in a spastic rigidity, but the noise was substantially muffled by what Twilight recognized in the gloom as a second mare putting both forehooves over the maid’s face. In a stunning flash of insight, Twilight recognized the spasming batpony as Laminia, the maid assigned to the human, only naked without the cloak she normally wore over her wings. That meant the other batpony was the missing guard, who was supposed to be standing where Twilight was now, not straddling Doctor Walther’s face and pressing her private bits against his face. The thought of just what they were doing there sent Twilight’s own private parts into a fierce tremor of their own, locking her abdomen muscles into reflexive spasm and sending surges of fire up her nerves.

She held herself there for a long time, perhaps minutes, as the maid cleaned Doctor Walthers phallus with her vagina, most probably sucking up his ejaculate with her ongoing repeated spasms. The frantic cries of pleasure matching Laminia’s jerky motions were muffled by the female guard’s forehooves, but they still tunneled through Twilight’s ears and into her mind like sparks of magnesium in a bath of pure alcohol. She could feel the human’s phallus stuffed up her needful vagina like he was doing to the lowly maid, who most likely would not even take notes or write a paper on the result.

It was a travesty of the greatest order. She wanted to slip into the room and give this interspecies experience the scientific study it deserved. After all, it was an extension of the same friendship studies she supposedly was failing, with emphasis on the stud.

The immediate problem was the uncertainty of the situation, along with the physical limitations of humans. Even if she convinced the doctor to allow her participation in the sexual experience, which was not a certainty, she would be third in line for his phallus, or maybe more if the frantic batpony currently milking it would not give up after her turn was over. Humans were sexual animals, but there were limits. Her own vagina gave a trembling spasm at the thought of being left out in the cold, which after watching the ongoing sexual encounter for a period of time, she realized was only amplified by the close presence of the door guard. His warm breath was brushing down on the back of her neck, right at the same spot that a stallion would sink his teeth in during proper traditional coitus in order to trigger a mare’s hormones.

Twilight turned her head slightly to give a brief glance at the entranced guard, who was paying her little or no attention at all to her while his eyes were fairly riveted to the bobbing and moaning of the slim batpony. He was obviously sexually excited due to the dark phallus jutting out from under his belly, a natural reaction to the sweaty and sloppy sex going on in the other room. Her own thighs quivered in anticipation with every breath down her neck, and for one tiny instant, she thought about simply lifting her tail and allowing his natural mating instinct to take hold, right there in the corridor.

Instead, she turned back to watch the two batponies, the second of which had just closed her big golden eyes and stretched her wings as a massive tremor ripped through her body, most likely caused by the human’s tongue in her vagina. Sympathetic clenches in her own vagina ignited a fierce blaze, growing into an all-consuming forest fire when the maid began to grind up and down on the human’s phallus again, giving out loud pants and groans that would have attracted unwelcome attention if the suite had not been in an empty wing. Twilight took a deep breath, or at least as deep a breath as she could with the traitorous muscles of her barrel determined to resist her will, then managed to nudge the door closed with her nose, since her traitorous magic may have sparked or popped due to her own distraction.

She took a step backward into the hallway, considered her options, and made a decision.

“Mister,” she started, then paused with a sharp frown.

“Green Mountain,” prompted the guard as he fumbled the textbook out of his bag and tried to stand at attention, or at least not look as if his phallus was poking all the way out from under his belly, which it was.

“Twilight Sparkle,” she whispered with a nod of her head and a nervous lick of her dry lips. “Before I ask you anything, can you keep this privates… I mean private between us?”

Green Mountain nodded. “Whatever you—”

“Don’t talk,” said Twilight quickly. “First, I am in need of a good… pronging, I believe is the term, so I can walk at least. Would you be willing?”

The guard opened his mouth to respond, then nodded instead, allowing the textbook to fall out of his grasp and back onto the bookbag.

“And to your knowledge, are you free of any communicable diseases, physical disorders, metaphysical ailments, psychological issues, or moral reasons why you should not prong me until I can get my hormones under control?”

The guard started to nod, then after a moment’s thought, continued the nod.

“And are you currently under any military orders that would interfere with my procedure?” she asked. “Because I don’t want to get either of us into trouble.”

“I’m not really a Royal Guard, I’m just a temp from the university drama department hired to fill holes on the roster,” he whispered. “It pays well, and I have permission to conduct educational activities while on duty so I can keep up on my studies.”

“Good.” Twilight snuck a peek at the protruding phallus poking out from under Green Mountain’s belly. “This should be educational for both of us, then. And dramatic. And fill a hole that needs filled. Also, have you ever pronged a mare before?”

“Uh… A few times.” Green Mountain swallowed. “Not like this, though.”

“Last,” said Twilight through clenched teeth as another series of cramps swept through her abdomen. “All I want is pronged. This is not an invitation to some sort of personal relationship with kissing and silly lovey notes. I don’t want stroked or nibbled or teased or cuddled. I don’t have time for it. Or foals,” she added while grinding her teeth. “I’m on my medication and I’ve got a contraceptive spell on. Prong me and we never see each other again. Deal?”

“Um…” Green Mountain lowered his voice to a nearly inaudible whisper. “Deal of course, but what if you need… pronged again sometime?”

Twilight bit her bottom lip and hobbled around until she could stumble her way back into the unoccupied suite, followed closely by the pegasus guard, who closed the door behind them. “Right now I need it right now,” she whispered in the dim illumination of the room

She lit her horn and started to take the armor off the not-guard, carefully as not to remove anything that was attached to the stallion and trying not to look at the part of him that her body was crying out for. As each piece of armor was removed, his natural color and build emerged from under the armor’s illusionary shell, and one additional fact became obvious when the image of his wings faded and vanished.

“You’re an earth pony,” whispered Twilight Sparkle, giving the hefty green stallion a quick examination. “With a unicorn horn cutie mark. Why… Oh, screw it.”

She heaved her rear around and yanked her tail to one side, trying not to say anything more that could distract the stallion from the assignment she wanted him to do. It seemed to take Green Mountain forever to lift his forelegs and drape over her back, allowing his rigid phallus to prod at her rear. In her impatience, she almost grabbed with her magic to guide it into the correct position, but the instincts of many generations of ponies brought his poking phallus into the entrance of her impatient vagina.

And there it stuck.

Green Mountain shifted positions, seeing if a little motion to one side or another would encourage entry into her locked passage, but to no avail. She wriggled her own rear, trying to line up what she could feel with where she wanted it, and her overwhelming sense of frustration only grew when Tab A absolutely refused to fit into Slot B. Twilight could move around until it touched where she needed it to go, and even could make it slide in just a tiny fraction of an inch, but that was it. Her frustration had closed off the very hole that she needed opened in order to assuage her frustration, which only made her more frustrated than ever in an ever-accelerating exponential series that could only end badly.

Vagina: Hey, you can’t come in here!
Brain: Let it in, you traitor!
Vagina: No way. Remember hygiene class? Those things are full of germs. Think about what our parents taught us.
Brain: What, you think they didn’t do this? Let it in or I’ll go crazy!
Vagina: Huh-uh. This door is closed. And don’t try the other one, or I’ll lock it too.
Brain: Yuch! Open up or I’ll use my horn to—
Horn: Don’t drag me into this. I’m still spitting sparks. I hope the rugs don’t catch on fire.
Vagina: Ha! I win.
Brain: Okay, you asked for it.

“Ram it in!” Twilight Sparkle shoved her rear backwards as Green Mountain’s phallus bounced off the clenched knot of her dripping vagina again. “Just ram it! I don’t care anymore! Shove your… cock in me!”

That was it. She had used the word. Real ladies did not use that word. Even guards, or temporary employees hired to stand around like real guards, must have been repulsed by her use of the profanity, because Green Mountain backed up and slid off her flanks. She had just opened her mouth to beg forgiveness when the most wonderful thing happened.

Something brushed up against her dripping rear, making her spasming muscles lock into a ricticus of iron and her breath catch in her throat. The sensation moved, gently exploring, softly licking, making the fire that wanted to consume Twilight’s entire body flare up and up and…

Her muscles locked around her barrel when the vaginal spasms turned into a long, powerful clench, forcing Twilight to give out a low moan. Then, once the faint blue sparkles on the walls reminded her brain that the only pony who could hear her pleasure was the stallion causing it, she gave in to the pleasure and moaned even louder.

“Yessss,” she hissed, not even caring to use proper grammar when the spasm passed and the curious tongue proceeded to poke around in new areas. “Oh, yessss… yike!”

The tiny nub of her clitoris had emerged from behind its defensive walls to see what was going on, and got licked for its troubles. A lightning bolt of pure pleasure smashed down into her vagina… no, her pussy, traveled up her spine, and lodged in Twilight’s brain, making little violet sparks drift to the floor as her magic discharged randomly.

Then he went away from that sensitive nub, and Twilight almost cried. Well, except for the continuing barrage of sensory impressions coming up from her twitching pussy that swirled and surged around her. Like a mathematician defining a complex fractal on a field of nerve endings, that devilish tongue traced its path around her nether regions, stopping for a moment here or spending a little extra time there in a pattern which Twilight could vaguely determine was guided by her own moans and pants of pleasure.

The scientist! He’s using my reactions to shape his actions in a positive feedback loop designed to accentuate my pleasure! He’s plotting out my most sensitive areas without even writing down notes! What if he forgets where they are the next time I need this? He’ll have to explore all over again… well, that’s not a bad thing, per se. And it could reveal points on the chart he missed the first time. Although he’s not missing anything now, including… ahhh, that spot really needs mapped when we’re done.

Waves of pleasure swept up her body, cresting in explosive fury and ebbing into brief periods where she could catch her breath, like a sine wave function in an interference pattern with his own rhythm, and when the two waves crested at the same time… ughh!!

A mare’s hind legs are strong to hold up a stallion in the act of rutting, but Twilight’s scrambled nerve endings had been sending conflicting signals to her muscles for what seemed⁽*⁾ like days.
(*) Chronal compression during intercourse. Look up afterward.
—

With a huff of breath and a quiet ‘Oof!’ Twilight Sparkle collapsed forward onto the room’s rug with Green Mountain’s delightful nose still buried in her quivering quim. It was an insanely uncomfortable position, but one that was quickly rectified when the powerful earth pony stallion rolled her over on her back to continue comfortable cunnilingus. The inverted position made holding her tail up optional, which was a good thing because Twilight was more than a little unsteady with maintaining any continuous muscular contraction other than one.

The surges of pleasure sweeping over her body overwhelmed Twilight’s rational brain and mangled any attempt at a functional language center to give voice to anything but low grunts and high-pitched squeals. No such problem existed for her hindquarters, which were carrying out their motions completely independent of any thought, including the way she lifted her hind legs and wrapped them around Green Mountain’s head to hold him tight during the contractions and to nudge him deeper when he was not applying his tongue where it needed to be right now. Waves and bursts of pleasure turned off her conscious mind, surrendering her willpower to instincts as old as ponykind. She grunted and groaned beneath his teeth and tongue, unable to resist even if she had wanted to with the electrical bursts of muscle spasms sweeping through her brain. There was no dispassionate scientist in the room any more, no student in magical studies, just a mare in thrall to her emotions and hormones.

And then Green Mountain took her clitoris between his teeth and everything happened at once.

She was vaguely aware of the screaming. All hers, of course, since Green Mountain’s head was being mashed into her pussy as hard as she could while the rest of her limbs flailed about. Drifting little flecks of purple magic floated around the room with every smashing hammer of pleasure slamming through her body, and she could hear her joints pop under the unexpected muscular contractions. Even better, the sledgehammer of pleasure continued to beat her nerve endings into a pulp, over and over and over with every flick of his tongue and twitch of her muscles. She wanted the sensation to continue forever, but neurotransmitters are finite, and it was not to be.

Step by step, the frenzied spasms that held her rigid as steel slowed, decreasing in frequency but not in intensity as she jerked and twitched to the tune of her hormone soaked sub-brain while frantically panting to make up for holding her breath during the slamming orgasm.

It took a few moments until she could relax her hind legs enough not to suffocate Green Mountain, who must have been holding his own breath during her convulsions or able to breathe through his adorable ears. They spent a few minutes just breathing until Twilight Sparkle, the greatest genius in Canterlot and master of several academic specialties, managed to compress the entire experience into one breathy, “Wow.”

In response, Green Mountain blew a cool breath across her overheated pussy, making little twitches and spasms chase each other across her overloaded neural pathways.

“Oooo,” hissed Twilight, although she moved her hind legs lower and nudged the perpetrator. “Don’t do that. Come up here so we can cuddle.”

“I thought you didn’t want any cuddling,” said Green Mountain, punctuating his words with a brief puff of air across her pubic hair and exposed clit, followed by a gentle lick that caused her legs to tremble and clutch against his body.

“You’re teasing,” she whispered once she could think straight. “If you keep that up, we’ll be doing it again, and I won’t be able to walk straight. So come up here.”

“Your wish is my command.” Green Mountain began to nip his way up her waist, making Twilight’s pussy give out a little twitch of regret with every nibble or bite tracing a path away. He took his time, nibbling and nuzzling along her thighs until he found her tiny nipples hidden against her tight virginal udder. With her own breath caught in her throat, Twilight felt his hot breath pass over the left nipple, then the right, then back to the left again. “Decisions, decision,” he whispered, then descended on a nipple and flicked—

Twilight’s world dissolved into flaming chaos again, like an overheated fluid being poured over a soluble precipitate that triggered an explosive exothermic reaction. She was vaguely aware of locking her hind legs behind Green Mountain’s mane once more and holding him with all her strength, since there was no chance of suffocating him against one tit or another. Muscles and nerves she thought had been broken forever sprang back into action, slamming a series of electrical strikes across her belly with every rake of his teeth across a bare nipple. She bucked against his weight, bouncing the hefty stallion off the ground at times when he hit a particularly good spot and doubling up to where she could bury her nose in his wildflower-scented mane when her stomach muscles spasmed.

Good thing he’s not a unicorn or that would have hurt oh he’s doing it again!

She could not hold still under his relentless assault on her nursing equipment, and worse, her magic was a sneaky traitor to her attempts at regaining control. Pillows from the suite’s bed took flight during a particularly energetic bit of nipple-flicking, and she barely managed to wrap her forelegs around one and bite down on it rather than endanger one of Green Mountain’s most probably fragile ears. She flailed and flopped under his nibbles until the fire got too hot for her to withstand and she shoved his nose back down where it belonged, then used her magic to cram a pillow under the small of her hips to lift her hot pussy up to matching hot lips.

Much better leverage! Make note for later. Too busy now.

The second time up the hill was a different experience with fewer uncontrolled spasms and more deep sensations, pouring through her hips and loins like a hot oil massage and releasing knots of frustrated tension she had not known about. Her hips moved on their own, shifting Green Mountain’s head up and down her hungry slit as the urges struck, and feeling echoes of pleasure rebound from all of her insides.

She was a slave to his every motion, every touch of his tongue, every gust of hot breath blowing across her sensitive spots. If Green Mountain wanted, he could have thrown her forward on her belly to ram his phallus up her hungry pussy and she would not have been able to object in the least. He could even have slapped her on the flank as some of her books said happened during sex and she would have loved it. Whatever he did was good, even if it would have disgusted her otherwise rational mind, but he did not take advantage of her vulnerability for any vulgar reasons. She was his slave, while he was a good master of her body, devoted into allowing it to experience all of the pleasure she could possibly embrace and coaxing out even more of her passion until Twilight was exceedingly glad that unicorn magic became disjointed during sex, or all of Canterlot would have wondered just why the sun was rising in the middle of the night and burning with purple flames.

Every nip and lick made her determined to keep and hold this extraordinary sensation for future study, and she had just the right study buddy in mind, trapped between her hind legs and nibbling…

there oh yes oh yes oh yes

A second scream of ecstasy echoed through the room as Twilight’s pussy clenched under Green Mountain’s oral assault. It was better than the first time in that she could feel every atom of her body from the tip of her tail to her sparking horn, a synchronized vibration that swept her away on wings of passion up to the sun and left her a toasty golden brown all over. It lasted far longer than the last time, filling her mind with more ideas than she could have written on an entire library of notes even if she could find the words. It was like being a library, filled with information and being read by an attentive student.

As the real world slowly resumed around Twilight, she continued gasping for breath and unclenched her hind legs so she could feel the stallion’s hot breath blowing across her tired pussy also. The pillow Twilight had clenched to her chest was somewhat the worse for wear, having at least two bites taken out of it and small downy feathers beginning to leak onto the rug.

“Oh,” she moaned once she had enough air to talk. “That was wonderful.”

“I’m glad you liked it,” rumbled Green Mountain, blowing a stream of cool air across her burning slit to cool it down.

“That’s pretty good too,” she admitted, wriggling under the chilly gusts that she needed to calm down. It was not sex, but a wonderful outlier on the data that deserved greater study at a later date. Possibly even a whole experimental series over many years.

Twice! She had never orgasmed with a stallion's nose up her pussy before, and now she had done it twice! Twilight Sparkle, being Twilight Sparkle of course, felt an immediate need to jump off the rug and find some paper to record her mental notes of the sexual encounter. That would discourage Green Mountain from blowing across her pussy, though.

Decisions, decisions.

“Cuddles,” said Twilight, moving the torn pillow off her chest with her wobbly magic and tossing it onto the floor a short distance away for later repair spells.

“Yes, ma’am.”

His voice held a tiny thread of disappointment, and he moved slowly up her tingling body as before, only avoiding nipple nibbling. With every nip and cautious bite, Twilight could feel a little chill begin to creep into her blazing warmth. After all, she had reached (and passed) orgasm twice, and the considerate stallion had not even gotten his phallus touched in the process. If the male earth pony had the same physiological reflexes and effects as a female unicorn pony, she might even be causing him injury though unreleased tension. That much blood channeled into his rigid phallus over a long time could damage internal pressure release mechanisms, making it so he might not ever be able to achieve rigidity again.

While he nipped his way up her trembling tummy, Twilight lit her horn up ever so slightly and reached down underneath the considerate stallion. Her touch was not as subtle as she wanted since Green Mountain moaned quietly into her belly fluff and shuddered slightly when she moved her magic down his rigid phallus to check on his condition.

It was worse than she thought. He was fairly rod-like with restrained blood to the point where she could feel a rhythmic pulse at the base of his shaft where the warm fuzziness of his testicles began. They were nice balls, firm and tightly tucked next to his body instead of the human’s dangling dark sack. They were stallion balls, far better to snug up to the opening of a mare’s pussy during a full thrust and tickle her on the ass. Using as delicate a touch as she was able, Twilight sent her magic sweeping to the other end of his phallus where a long stream of sticky fluid was dripping. For a moment, she thought he had orgasmed while she was having her pussy licked, but there was insufficient volume of ejaculate to account for that kind of release, and besides, his phallus was still over-rigid.

For one brief moment, Twilight considered sliding down to his phallus and taking it in her mouth to perform the same release on Green Mountain as he had for her. It certainly could not be that distasteful, because she had heard other mares talk about ‘giving head’ to give their stallions relief, and although they wrinkled up their noses and made faces, she had noticed their tails always twitched while they were complaining. The problem was she had a complete lack of experience with the process, other than it was supposed to involve sucking of some sort, and possibly blowing.

Besides, he seemed to be enjoying the touch of her magic from the moaning he did every time she brushed it against his phallus. She dipped her magic into the pussy juice she had in excess and smeared it around the tip of his shaft to an even more energetic moan/applause, then started to paint the rest with little dibs and dabs of her own special paint.

It might have been an accident or just her own rebellious magic that dragged the tip of Green Mountain’s phallus into the mouth of her pussy just as he moved forward in reflexive humping of her slippery magic. One short hump became two, and a little more progress inside, then three, and four in rapid succession until her mind became aware of what was going on.

Vagina: Hey, it snuck part of the way in while I wasn’t looking!
Brain: So it did. See how much will fit in this position.
Horn: I’m trying.
Vagina: No way. I’m going to clamp down and keep this from going any further.
Muscles: With what? We’re tired, and this is nice.
Vagina: It’s not supposed to be here! It’s… Hey, that is nice.
Brain: See. Told you. Now let it the rest of the way in. Yeah, like that.
Horn: I can’t hold onto it any more. Too much of it is inside.
Pussy: Take a break, I’ve got this. And from now on, you can call me Pussy.
Brain: You have reached Twilight Sparkle’s mind. She’s not in right now, so if you will leave a message…

Ponies were not supposed to have intercourse in this human position. All of the important bits were in awkward places, although the pillow under her hips and Green Mountain’s flexibility helped…

Actually, it was not bad at all. Particularly since Twilight was unsure of her ability to stand up. And in this position, she could reach down and nuzzle Green Mountain around the ears. The hefty stallion was a little heavy while resting across her belly, and his eyes looked a little glazed, but there was something wonderful happening down below.

Twilight was getting bucked.

No, not quite.

Twilight was bucking Green Mountain.

Not all of his rigid phallus was nestled into her hot pussy, just enough to press into the areas that needed it and rub against all the right nerve endings that had been ignored during her previous two orgasms. The position was a very human experience, which was similar to the human experience that the batpony maid next door was going through yet again, if the pleasured shrieks Laminia was making were any guide. For a moment, Twilight tried to imagine the human’s phallus stuffed up her pussy in this fashion, but reality was more interesting than her fantasies, particularly when she began rocking Green Mountain back and forth, letting his lubricated phallus slide in and out of her twitchy pussy.

That is not a phallus. That is a cock. Context is everything.

Bucking was… different, far different than oral sex. That slithering length of cock slid along whole chains of firing nerve cells in a way that left the next nerve anticipating the arrival, then signaling the departure to other happy nerve endings. The bursts of Green Mountain’s breath against her chest were likewise merged into her warm glow.

Seriously, all she had to do was allow her body to ripple and twitch, grabbing and clutching at his cock the way she wanted to, and Green Mountain’s face went all absent-like, as if his brain had been sucked down to his balls and was presently rubbing around Twilight’s soggy pussy. He gave out animalistic grunts as he rutted her deeper, his language centers flooded by primal lust, but she could see little flickers of intelligence surface. It was a power that Twilight had never experienced before, a position of control and domination over a stallion that being pronged could never give her. She could open her thighs and press him in deeper, or squeeze her legs together and leave only the very end of his cock teasing in her entrance.

She was a goddess commanding worship from her loyal subject, a being of pure sexuality driven by hormones and existential forces of nature to consume and produce pleasure. If she could use her horn, she would be able to raise the sun and moon together and juggle them while singing. Maybe this was why unicorn magic became unstable when other areas of the brain were stimulated.

It was worth further study, certainly, and he was too. Far too many stallions would have just rammed their way into her reluctant pussy and most probably wandered away once her lust had been satiated. This one was considerate, putting her own needs in front of his own. There was something a little more that she noticed while nuzzling the top of his mane, because Green Mountain had his eyes closed and was biting his bottom lip as if he were concentrating on… Oh!

He’s holding his orgasm back! He’s letting me control his body, and if he orgasmed, his cock would get all floppy and be unable to rub… ahhh, right there.

It was another sign that this stallion warranted further examination for a longer-term relationship, if he were available. He was maintaining a little fleck of intelligence in his rutting brain to keep from giving up an orgasm, just for Twilight’s pleasure. Well, it certainly was not unpleasurable for him, but Twilight was willing to give him that benefit of the doubt.

The rules of the game had changed, and Twilight felt an unexpected twinge of joy in her heart as she relaxed her hind legs and got a better grip on Green Mountain’s warm back. He may have thought he was able to hold his orgasm back, but Twilight Sparkle wanted that orgasm, she wanted to feel his cock pumping semen into her depths, something she had never experienced before.

She was not going to be denied.

Giving a thrust to her hips assisted by her firm grip across his back, she humped his rigid cock deeper into her pussy than he had been able to get so far, then clamped down on it with twitching pussy muscles while letting it slide back out. It must have been as pleasurable for him as it was for Twilight because of the way Green Mountain took in a sharp breath and bit down on his bottom lip harder, then let go of his bite on her second clutching thrust in order to pant for breath.

“You… sure?” he gasped. “Foals?”

“No foals,” she moaned, giving another long, slow slither up and down his rigid shaft. “Want your cum,” she added. “Want you to comeeeeaaaahh…”

Her own neurons had been milked fairly dry of their neurotransmitter load, but there was enough left to trigger a lightning storm in her brain that sent her pussy into jerking twitches, matched by Green Mountain’s rigid cock throbbing as he gasped for breath with the most peculiar expression on his face. It was fascinating, although most of her brain was busy with her third orgasm and the subdued feeling of his cock pulsing out bursts of cum into her hungry pussy. It was better than she had expected, and if orgasms kept getting better at this exponential rate, she would kick herself for not getting started earlier. The only thing she could possibly criticize was the descriptions in the books she had read. The books had claimed a stallion ejaculating was an earth-shaking experience for the mare, and while the process to it had been unspeakably pleasurable, she easily could have missed the actual event. It would take further study to see if perhaps there was something she had not done correctly, or maybe a correction after enough data points had been collected. In any event, it would wait for later.

The now was much better.

When she regained control over her own body, Twilight sent a long, slow pulse of pussy compression against Green Mountain’s cock, only to feel the rigid shaft pulse back in return with perhaps the last drip of his cum. Still panting, the stallion had slumped down across her ribs with every hot breath stirring the thick portion of her chest floof that she had never seen the reason for getting trimmed. It made Twilight aware of the oil stains she had gained during her stint as Blueblood’s mechanic, the sweat soaking her coat, and the faint scent of gasoline that still clung to her belly where she had been lying under the car. She sent her magic gently touching down his body, brushing up against his clean mane and coat until she reached the fuzzy lump of his balls.

“You don’t mind the way I smell?” she asked to cover her cautious magical groping. “I got awfully dirty today.”

“You smell wonderful,” he whispered, nuzzling his nose into her belly fluff. “Like books and sweat and more books and gasoline.” He made a growling noise deep in his chest like a purring panther, which made her entire lower belly tingle with the vibration. “You’re a high-powered machine,” he murmured, nibbling along her chest with little nips and nuzzles that left a trail of fire behind. “A piston-powered V-8 at least, with a supercharger.”

Nether bits with a mind of their own clenched down on the piston in her cylinder and determined it was still rigid enough to be stroked, even if hammering was off the table for now. Her hips moved fractionally on their own, swallowing up a little more of the less than rigid phallus… no, cock, and feeling it respond to her inner caress by swelling up to fit juuuust right again.

Twilight Sparkle had needed this far more than she realized. The frustrations of the day had built up in little cramps and tense muscles all over her body that a good pronging flushed out in a most delightful way.

The only thing missing was the actual pronging.

She toyed with his balls while Green Mountain nuzzled against her chest. He had been an exceedingly polite first-time lover, kind and considerate beyond anything she had expected. Still, she had not been pronged, and there was still a small but detectable itch deep inside her which Green Mountain’s rigid cock could not reach while she was in this position. Equine internal organs were the size and shape they were for a good reason, after all. And he was still rigid, so there was a possibility of just one more orgasm out of him. After all, it was the ultimate domination of a stallion over a mare, and she had already had her turn. Three times, in fact, although only the last was in a position where she was in control

She clenched her muscles and judged the throbbing pulse from his cock that followed.

“I’ve got a question,” she whispered while nuzzling at his mane.

“Just one?” Green Mountain moved across her chest, giving it one last tantalizing nuzzle before looking up at her with sparkling blue eyes. “I didn’t know there would be a test afterward, or I would have studied harder.”

“Oh, trust me,” said Twilight with another twitch. “I plan on studying harder with you a lot.”

“I’ve never looked forward to pop quizzes more,” said Green Mountain, blowing a long breath into her sweaty chest floof.

“You’ve got straight A’s so far. Actually, I’ve got two questions. Would you mind if we did this—” she twitched her pussy and reveled in the hefty throb that followed “— again sometime later? On a regular basis. Whenever we both have time.”

“I can make as much time for you as you desire.” Green Mountain gave one last puff of air against her chest before trying to get up, only to have Twilight refuse to unlock her hind legs from behind his back.

“Not yet,” she cautioned. “I know that’s what always happens in the books right after sex, but…” Her horn lit up and several towels took erratic flight from the bathroom, one of which reached its target and tucked itself in underneath them.

“I can stay here as long as you like, Miss Sparkle.” He wriggled his hips slightly, making her pussy involuntarily twitch in return. “I never did understand why couples uncoupled after sex either.”

“Ohhh, bad pun.” Twilight stressed her tired tummy muscles in order to lift herself enough to give Green Mountain a kiss on the lips, which was messy and tasted far different than she expected from her own juices, but not bad at all. It also was far, far different than she ever anticipated her first kiss with a stallion to go, and brought to mind one more important point. “And if we are to have sex again, you should call me Twilight. Never Miss Sparkle, and particularly not Twily. Just Twilight.”

“With incentive like that, how could I ever refuse?” said Green Mountain with a sticky smile. “Just Twilight.”

“Ow.” Twilight wrinkled up her nose. “For that, I shouldn’t ask you the next question, Mister Mountain.”

“I’ll take it as extra credit on my test,” said Green Mountain, “if you promise to call me Greenie. It’s closer to my real name, since they wanted me to use a different name while acting as a guard.” He wriggled his hips and gave Twilight a short thrust with his rigid cock. “You are the princess of my pecker, and your wish is my desire.”

“Would you mount me and buck me senseless?” asked Twilight before she could reconsider. “I mean I’ve come three times now, and you’ve only gone once, so that’s not a very good ratio if we’re going to have sex later and you’re still erect so you can if you want to and—” Twilight Sparkle tried to stop but having a hot cock in her pussy was a lot like being dosed with truth serum “—I want to see if you’re as considerate a lover when you’re dominating my ass and ramming your cock into my pussy as you have been so far so I can consider your qualifications for a longer-term position.”

Greenie blinked, and Twilight could feel his cock soften in her pussy as he thought. It seemed a shame that sex organs took as much blood flow to operate as brains, but she supposed it was a compromise. “It sounds like you’re considering me for more than just sex,” he said slowly. “Not that I’m reluctant at all, but you really don’t know much about me.”

“Every pony starts out not knowing anything about who they meet,” said Twilight, trying to keep from pumping against his softening cock. “How can we learn more about each other without intercourse? Social intercourse too, of course.”

“So, bucking tonight, and breakfast with coffee tomorrow? Isn’t that backwards from normal?” he asked. It sounded reluctant, but she could feel his cock swelling inside her again, which worked just fine as an impromptu lie detector.

“Bucking tonight, breakfast tomorrow if I’m satisfied with your performance grade, and you think… um…” Twilight stammered to a stop, only to have Greenie give her a prod with his cock at the same time as a nip on her chest.

“I hereby grade your score so far as A+ with extra credit points,” said Greenie, nuzzling up her chest and to the hollow of her neck. “You are an excellent student who has exceeded all of my expectations.”

“Mmmm,” purred Twilight with a long, slow stroke down his firming cock. “Tell me more.”

“In fact, you have gone beyond my experience as a teacher,” admitted Greenie through his nips at the edge of Twilight’s sensitive trachea, “and any further lessons will have to involve mutual experimentation.”

“Most of my experiments involve explosions,” groaned Twilight with her head tilted back to make more space for his nipping teeth.

“Good. I like explosions.”

A clawing need in Twilight’s belly made her push Greenie away and roll over, standing up on unsteady legs. She flagged her tail to one side and braced herself. “Experiment one,” she breathed. “Bucking. Begin.”

There was no resistance at all this time when Greenie rested his weight on her hips and pressed his rigid cock into her waiting pussy. She did not even get the opportunity to guide him in, but sucked in a breath as the long shaft, far longer than she expected, began slithering into the waiting slot. He pressed forward gently, as if he were dreading the slightest twitch of pain on her part, then rocked back. Each time he penetrated a little further, allowing his cock to slide into her pussy, then back a little, then in a little more, until his fuzzy balls rested against her twitching pussy lips.

“So,” she heard as Green Mountain nuzzled on the back of her mane and up the back of her head in the direction of her overheated ears, “are you feeling dominated?”

She was. All of the parts of her insides touched against his rigid cock, which swelled even more as an involuntary spasm twitched the inside of her pussy. This was nothing like the bucking she had been begging for earlier, and no amount of ramming or cramming would have been a tenth as good as the ocean of pleasure that she was swimming in now. She could feel his pulse of all things, hammering away against hers in syncopated rhythm where their engorged blood vessels pressed against each other. He was her stallion, and she was his mare in this position, fully spread for every thrust of his hips and bearing his weight without even the slightest tremor in her knees. It made her want to disrupt the birth control spell and let him pour his seed into her fertile valley so she could be a mother to as many children as she could handle, to have him sweep them up into a cloud and make it rain all over the valley with her pleasure, to join her magic to his in a mingled spell where their bodies would be cast aside and their power could pierce the cosmos in search of new knowledge.

For one long timeless moment, she reveled in the sensations, the feel of hot juices dripping down her leg, the little bubbles of air trapped in her pussy that tried to escape along the lubricated cock/pussy interface, the inner twitch of her ovaries as they were magically thwarted in their mindless attempt to send out an egg or two for proper fertilization.

Well, maybe the last was only in her mind.

Even as dominated as she felt, she could sense Greenie trying to keep as much of his weight off her as possible, the trembling gentleness that he used when pressing his cock into her hungry pussy as if to be ready to pull out if she expressed the slightest pain, the tender nibbles he was bestowing on the back of her neck instead of the hungry bites she really wanted.

“Shh,” she whispered. “Less talking, more bucking.”

She almost cried when he slid backwards, letting his rigid cock glide out of her clutching pussy, but her instincts knew what was coming next. She braced her legs when he slid forward, sliding his cock back into her impatient embrace with a distracting squishy noise that almost made her giggle. It did not help her self-control that his fuzzy balls slid right up to the opening of her pussy, brushing and tickling the hairs they intertwined with, then giving another tickle as Greenie slid back for the next thrust.

Twilight Sparkle was getting bucked. And she would not have traded it for the world.

Self-recrimination about her previous impatience with Greenie would wait for later, as well as any dating questionnaires or the inevitable embarrassing introduction to Twilight’s little dragon brother, and her big Royal Guard brother. All of that was problems for Future Twilight, as well as any bucking that Future Twilight was going to get later. Right now, Present Twilight was determined to milk every bit of pleasure she could out of the limited time she had. Sheer physical restrictions meant she would not be able to endure under the pleasant bucking she was receiving longer than… well, time was not important, only that it would eventually end, and right now it was in her best interest to squeeze as much pleasure out of getting bucked as possible.

Leaning into each long, slow thrust, Twilight could not resist and did not want to resist her urge to moan and groan with the bucking she was receiving. Greenie was still using her pleasurable reactions to adjust his technique, and she was giving lots of feedback for reference, as well as getting lots of just plain bucking. It was rowing in a fog of pleasure with rhythmic stroke, stroke, strokes that kept scrambling Twilight’s brain as she attempted to make mental notes about which exact motions gave the most pleasure while said pleasure happily got into her neural synapses and proceeded to throw them into lightning storms of ecstasy. She was just thinking how she wished this could continue forever when she managed to turn her head enough to get a glimpse of Greenie stretched across her back with his eyes closed and biting his bottom lip.

He’s holding his orgasm back for me again! The idiot! If I come, he’s going to wind up having to take care of his erection with some inferior substitute, since I’ll be flat on the floor. Well, we will see about that!

Their bucking had evolved into a rocking motion, a cyclical sine/cosine wave that Twilight began to modify by ramming her rear into Greenie’s cock when he thrust forward, then grabbing onto the escaping cock with a clench of her tired pussy muscles. The frequency of their oscillations began to increase, along with Greenie’s hot breath down the back of her neck. A second glance backward showed that he had quit biting his bottom lip, and a moment later when he sunk his teeth into the sensitive part of Twilight’s neck, she understood why.

The bite drove her crazy, but Greenie’s weight kept her from flailing around more than just internally. She could feel his cock swell even further as he began to grunt incoherently, ramming his cock repeatedly all the way into her pussy right up to his balls.

Wait for it, waitoforit, stopwaitingohstarsandheavens!!!

With one final stentorian grunt, Green Mountain rammed his entire cock into her pussy and held it there. Through the spasms and sparks of her own orgasm, she could feel his hot balls twitch and the waves of cum spraying around her inner depths, right where he would need to be in order to ensure maximum fertilization of her waiting eggs. She kept the pressure up against him, trying her best to milk out every drop of the precious fluid and even nibble on his flattened balls with the lips of her pussy. Despite her best efforts, his crushing embrace around her barrel began to slacken as he sucked in huge gasps of air, and the electric pulsing of his cock slowed to a twitch, then nothing.

Well, not nothing. More like everything, but since she was in the middle of everything tingling and twitching at once, it made differentiating the sensations difficult. In fact, she could not tell where the Greenie/Twilight interface began, since she could have sworn for a moment that she was rammed just as deep into him as he was in her, most probably by crossed neural circuits that had overloaded during the event.

And with both of them gasping for breath, the return of reality came with a price. Her knees wobbled, and she could feel his softening cock begin to slither out the mouth of her pussy despite a last-ditch effort to suck it back in. Then ever so slowly, with each of them trying their best to reduce the collapse to a manageable descent, they wound up back on the rug’s pillows.

“Uhhh,” groaned Greenie as he moved up to beside her, but that was the extent of his verbal exertion. Twilight Sparkle tried to say something in return, but all of the sparkling going on in her brain was still echoing around inside her skull, so she settled for resting her cheek against his and nuzzling. Finally, after putting one foreleg over her side and nuzzling back, he kissed her.

“We are so going about this backwards,” he managed after they had clung to each other’s sticky lips for a while. “Bucking first, kissing next, and then a date.” He did not move away when Twilight threw a back leg over him and let it dangle there, since that was as much muscular motion as she was capable of at the moment. However, after a few more gentle kisses, he nuzzled up to her ear and asked, “So, what grade do I get?”

Before Twilight’s brain could organize a response, her pussy sent a jolt up her spine and made all of the tired muscles of her belly involuntarily clench in a long series of spasms, leaving her clinging to Greenie as the bolts and jolts of pleasure chased around her nerve endings. She nuzzled in closer until her twitching belly was against his, rubbing up against the longer hairs of his belly and the sticky trail his cock had made when it slipped back into its sheath. “I’ll have to dock you a point for talking too much,” she whispered.

“I don’t think I can do extra credit,” he whispered back. “Not without some recharge time.”

Twilight Sparkle groped around with her magic and found one of the towels that she had dragged into the room, using it to wipe his face, then to bop him on the nose. “You have time to recharge. I think it’ll take me a week just to walk again.” She used her magic to stuff a towel under her dripping tail, then grabbed another pillow from the bed for her fellow student in the experiment.

“A week?” Greenie snuggled down and pulled her closer to his warm chest, which Twilight did not object to at all. “I can do that. Just wake me up then.”

“We are not going to sleep on the rug,” objected Twilight, although her mind promptly brought up just how far up she would have to climb to get onto the bed, and how comfortable she was at the moment. She nuzzled Greenie on the clean (well, cleaner) lips and distracted her pesky mind for a while, soaking deeper and deeper into his embrace. “For very long,” she added when they broke for air. She eyed Greenie, who was looking back with a distracting twinkle in his eyes. “What?”

“Just thinking. Since I haven’t been able to for the last hour or two.” They exchanged kisses again, and Twilight could feel his tail wrap around hers in the darkness that surrounded them when she used her magic to flip off the light. They nuzzled and nipped for a while in the dark before Twilight put her head down on his shoulder and let out a sigh.

“What if I go to sleep,” she started, “and when I get up, you’re not here? I mean so many of my books end that way with the stallion sneaking away and the lovelorn mare finding out later that he has a wife and five foals. Then she has to survive foalbirth and raising their illegitimate child without a father and becoming a business success and having her foal turn on her when he gets old enough to know who his father is and go storming off to confront him and find out that he passed away before he could really know his own offspring and—”

Twilight was pleased at how easily Greenie found her lips in the darkness, giving her a gentle kiss to cut off her babbling and picking up the conversation.

“It’ll never happen. Your brother, your teacher, and your… whatever Princess Cadence is to you, would track me down and drag me back if I ever made you the least bit unhappy. So,” added Greenie as he settled down on his pillow, “I’m more than happy to remain where you put me until we both find out where this leads.”

He opened one blue eye, which glittered in the dim lighting of the room. “Unless you snore,” he added. “That’s worth three points off your score, at least.”

With a giggle, Twilight settled down next to him and closed her eyes. “I’ll just have to do some extra credit, then.”

“Can’t hear you,” he murmured, nuzzling in closer to her ear, as well as the rest of her body. “Resting up for our big date tomorrow.”

It turned out he did snore. But it was quieter than Spike, so Twilight Sparkle decided not to deduct it from his final score.

Although when they both woke several hours later, she made another discovery that chased all thoughts about grades out of her head.

It turned out that a mixture of male semen and female arousal fluids when smeared onto two pony coats made an extremely effective glue.

Traveling Tutor - The Quiet Tree

The Traveling Tutor and the Royal Exam (M-rated post-credit scene)
The Quiet Tree

There were times when Green Grass woke up in the middle of the night just to lie there and think. And there were times when he woke up because Princess Twilight Sparkle shifted in her sleep. After all, he would never get used to wings on his own body, even in the unlikely event Green Grass were to discover some hither before unknown source of magic and ascend to the Aetherial Realm to become an alicorn. Come to think of it, two trips might be required, one for wings, and one for the horn that his parents had hoped for since the day he was born.

Admittedly, a horn might be useful in his career of tiny tot teacher. Most likely it would just get in the way and bonk his sleeping partner, like Twilight tended to do when she forgot she was not alone in bed.

Still, the midnight apologies were epic, and well worth the pain.

As for getting his own wings… no. He nuzzled down into the soft purple darkness that surrounded his nose and tried not to sneeze. Luck. Marrying a princess had absolutely nothing to do with his well-considered plans for the future and any skillset he might pretend to have mastered. It was pure luck. Neither of them had intended on this; Twilight had been perfectly happy with her friends, her books, and her brother the dragon, while Green Grass had worked so hard on achieving his dream of becoming a young unicorn magic tutor that he had shut everything else out of his life.

One hoof wandered a little lower on his wife’s still-trim barrel and touched ever so gently. In six more months or so, depending on alicorn physiology, a new life was going to emerge that would change both of their lives just as much as they had changed already or more. A life that they had created together without really intending on it. A life that existed because of… luck. And a minor confusion about teaspoons and tablespoons, to be honest.

There was the faint rustle of bedcovers and Twilight pressed closer to him, allowing the rougher hairs of her back to prickle along his sensitive belly and her tail to brush against more delicate areas. That was another change in his life he had never expected. The bed in her library tree was never really meant for two ponies to share, since the previous Ponyville librarian had been a hopeless spinster, and Twilight had never purchased another one. It would have taken valuable bits that were much better spent on books, after all. The compact space had given them a binary solution to sharing, even if he fell out of bed once or twice while getting used to it.

There was Sleeping Position #1, nose to nose and wrapped around each other. It was not really a sleeping position, per se, and frequently evolved into Not Sleeping At All Position 1A or 4A, depending on circumstances. Having such kissable lips at such close range was too much temptation for newlyweds after all. Then there was Sleeping Position #2 (face up) and #3 (face down) which worked alone or in combination as long as there was not too much moving around, and the snoring that #2 tended to produce was limited. Actually, that was not a bad thing either, because he liked laying there in bed, listening to the love of his life, and if it got too loud, he could easily nudge Twilight. Which turned into 1A or 4A on occasion also.

Sleeping Position #4 is what he found himself in now. Technically, it could probably be a lower number on the chart, or broken into two perhaps, since being wrapped around her back was not the same as her wrapped around his. There were subvariants on it, depending on if he had both forehooves wrapped around her, or just one so his leg would not fall asleep, or the full four limb embrace. And since Princess Twilight happened, that number could reach six limbs wrapped around him with all the rib-creaking strength that a worried or passionate alicorn could muster.

He liked #4. The only real downside on the him-wrapped-around-her variant was getting bonked in the nose by Twilight’s horn, which seemed longer now that she was an alicorn, but still just as hard.

Speaking of hard.

Nuzzing deeper into the cleft on Twilight’s back where her new wings came together, Green Grass gave a deep appreciative sniff. There was nothing like the scent of a sweaty alicorn, all mixed with damp feathers and book dust, and unmistakably his, his, his, to have and to hold for as long as he drew breath. It was entirely udderstandable… understandable how Spike would grow to immense size when the greed of dragonkind overcame him. There were times when Green Grass also felt as if he wanted to be sixty feet tall, striding through Ponyville and bellowing out his ownership of his precious treasure.

Treasures.

Getting married had been one thing, but having a child… His touching hoof gently brushed across Twilight’s soft belly hair and down to her trim udder. Mares had an advantage in bonding with their children since they joined their bodies together to feed. It was a connection that made Green Grass ever so slightly uncomfortable with nuzzling Twilight around her naughty bits because of his own memories of youth, and the way his mother had looked whenever Greenie’s younger sister was nursing. Still, Twilight had no problem with his own nuzzling there, and once the foal was born, that area was most probably going to be off-limits for a few months, so he gently brushed the frog of his hoof over them.

Again?

His older brother Graphite had once told Greenie that newlyweds should get a jar and put a pea in it every time they made love in the first year, then take a pea out of it every time after that. Quite contrary to what her friends thought, Twilight Sparkle would need a very large jar, and Green Grass did not think the contents would last very far into that second year. Being away from her for a day or two only made it worse, or better he supposed, like a make-up exam with extra credit. No, that was not a fair analogy. There was no testing or points in their relationship, just a fierce undeniable urge to return to each other whenever they were away. Twilight said she could sense the direction he was in whenever she was away with her friends on a friendship mission, just like her horn was the needle on a compass. He teased her about having much the same Twilight-pointer, only one that could not be brought out in polite company. That earned enough tickling to reduce him to a puddle, but totally worth it.

This afternoon when Twilight had met him at the train station, none of her friends had shown up, Spike had been given the rest of the day off, and the library had its ‘Closed - And We Mean It’ sign up. His teaching convention in Manehattan had only been a few days, but from Twilight’s response over the next few hours of their reunion, she must have felt like it had taken weeks. Female ponies had hormonal surges. Pregnant mares had them worse. Pregnant alicorns had… well, Green Grass was fairly sure she had been chewing on the headboard of the bed while he was gone. If Princess Celestia ever got pregnant, she’d probably need to rotate through an entire herd of husbands for their own survival. And he refused to think of just what Princess Luna was getting onto with his brother, Graphite

Twilight was perfectly happy with a herd of one. Green Grass was just glad he had gotten into this position gradually, and built up his endurance in the process.

So once this afternoon the moment they had stumbled into the library and locked the door, then again when they managed to make it up to the bedroom, then a third, far slower and more cautious time before a shower, unlocking the library door, and going to see their friends.

Their friends.

Well, mostly her friends with a lot of their friends mashed into it, but if one of them had a secret to share, they preferred to tell Twilight first. He supposed it was because they were all mares. He had friends in town too, although mostly younger students of his, who most certainly did not get told the things Twilight’s friends did.

One of which was happening at the moment, very slowly, very quietly, and very uniquely. It was a rare confluence of circumstance, positioning, attitude, and luck that left him in this exact position, feeling the overwhelming joy of their warm bodies pressed together with her tail flagged to one side as his cock ever so slowly began to emerge.

And as it emerged from his sheath, it had an extremely short distance to go before vanishing inside Twilight’s welcoming pussy. No pushing, no twisting, no attempting to get into just the right position. Just the ever so slow expansion of his cock, inch by inch progressing into the mare who he loved, without either of them having to shift positions in the slightest.

There was movement of course, ever so slow pulsations of previously pounded pussy gently pulling him further and further inside the hot, lubricated slot. And there was no way Twilight was still sleeping, as he had thought for a moment, because he caught the way she glanced one eye over her shoulder in the dim light of their bedroom. Lips pursed, the slightest nod, and a short jerk of the horn in the direction of Spike’s box on the other side of the bedroom conveyed all the need for quiet she could have managed with words and then some. Mostly because she took the opportunity to move his forehoof back to touching her rock-hard nipples again before putting her head back down on the pillow and breathing as quietly as she could.

Somehow, the need for silence made the act even more intense, and the rest of his cock emerged in a rush, nearly faster than Twilight’s hungry pussy could swallow it up. Tails twined together beneath them, his balls pressed up against her dripping entrance, and enough shifting in position that he could get a second forehoof brushing against her itchy nipples, he held his mare just as tight as he could, as if at any moment the universe would recognize its mistake and whisk her away.

The universe wouldn’t dare. Twilight Sparkle would kick its tail up between its legs.

Deep in her belly, Green Grass’ cock finished expanding to its full size, stretching already tight pussy walls and driving a tremor of lust through both mare and lover. Only the faintest whine of pleasure escaped from between Twilight’s clenched jaws, and Green Grass kept his own silence by burying his nose into her mane to get a good bite of the back of her neck. Her whine turned into a brief squeak and a sensation like liquid lava swept down his cock as Twilight spasmed, writhing in his grasp with the first of many small orgasms. Without her flailing around the bed, Green Grass found it far easier to tease up the back of her neck with his teeth, nipping and nibbling with every twitch and suppressed moan until a second wave of unbearable heat swept down her pussy, then a third.

It was a good thing they had already made love this afternoon, or he would not have been able to resist that kind of cock cooking. As much as he wanted to rear back and plunge her depths over and over, the tiny teakettle snore of Spike just a short distance away held him back to short presses against her unyielding muscular rear, microscopic withdrawals, and pressing forward again in a slow, steady rhythm that made the bed give out the smallest of squeaks. Every tiny noise Twilight made was matched by his own low grunts, muffled by bites and nips at the base of her wings until their subdued grunting fairly resonated between their barrels. Twilight’s nipples grew under his touch until they stuck out like little belly horns, and unable to catch them between his teeth and flick, he brushed them repeatedly with the edges of his hooves instead.

Beneath him, Twilight stopped breathing. Every muscle in her body locked into a rictus of pleasure including the ones holding his cock motionless, twitching and spasming with a blast of heat that Green Grass could not resist. Pressing forward the bare fraction of an inch that he was able, he released the pressure that had been building in his balls since she had begun rubbing her tail against his crotch. By chance, every twitch of his releasing balls matched a spasm of muscular clenching from Twilight, leaving the two of them resonating with the afterglow and holding absolutely still in the silence of the bedroom.

Spike had quit snoring.

They did not move except for breathing as silently as they could while Spike rearranged his blankets in his tiny bed. Green Grass could feel the cool of the evening air where their blanket had been kicked off their overheated bodies and the sharp chill of a cool breeze blowing over his damp balls, making his cock begin its slow withdrawal. It was a moment he wished he could hold onto forever instead of visiting every so often, but then he would not be able to experience other moments, such as their slow transition into Sleeping Position 1A, the soft caress of Twilight’s hot lips against his, and the eventual nuzzling of her sweaty face into his body, draped across his head to where her every breath tingled down the back of his neck for a change.

They needed no words.

Once Spike began snoring again, she nuzzled up to his ear and gave three quiet grunts.

I love you.

He leaned into the nuzzle, brushing up against the soft hairs against her throat and gave a matching four quiet grunts also.

I love you too.

And together, sticky and sweaty from their actions, perhaps a little overheated from the stuffy air of the oak library bedroom, mare and stallion slipped off into their dreams of the future.

As young ponies in love who would do this and much else, many, many more times over the years.

As a married couple who had grown so comfortable with each other that it was inconceivable to be without.

As future parents who would soon only find time for themselves snatched in minutes and seconds from their children.

As lovers who refused to measure their time together, but were determined to spend it in vast quantities, poured over the brim and flowing in all directions in their joy.

And as one dragon, who made up his mind to finally move his sleeping box to another room for good so he would not have to fake sleep whenever his big sister and her husband decided to have sex.

Author’s inline notes: This is a MATURE story, meant for readers who are old enough to drink, smoke, swear, and other such immature activities. It is considerably different than my usual fare, which is lighthearted and mostly G-rated. This story in particular follows Green Grass and Twilight Sparkle of The Traveling Tutor and the Librarian, Chapter 30, in a way that the original story could not go and still maintain its T rating. Originally written for Dirty Little Secret’s Dirty Little Contest except Green Grass is an OC, and therefore ineligible. That’s fine, because I got to expand my writing spectrum and maybe I’ll write something for it before the deadline.

The Traveling Tutor - Tree Temptations
Decisions Decisions

At precisely 8:27 A.M. on a Tuesday, Twilight Sparkle decided it was time to lose her virginity.

Or it could have been 8:28. She wasn’t exactly positive, since a certain period of time before that was spent in a strenuous tickle fight with the stallion she had determined would be the one to take said virginity, and there was the inevitable cooling-off period afterward, some panting, a great deal of kissing, et al…

Still, she made the decision while her mind was clear, not under duress, and certainly not due to the frequent poking she had been getting from said stallion’s warm cock, which had been nestled up against her belly for nearly the entire time the two of them had been awake this morning.

Yes, it was time. All of the relationship checkboxes up to this point had been dutifully checked, if possibly smudged slightly. First and foremost, Spike was outside of the library bedroom, and she had put a security and privacy spell around the room so no unexpected friends would come bouncing through the door or peek in through the balcony. On a longer scale, she had more-or-less kinda been keeping up with her morning doses of ovulation medication, and it was not her heat time anyway, so the probability of foals was infinitesimal. Not that she would mind foals, she just wanted them in a more structured fashion. Probably after marriage, which is where one of the smudged boxes on her checklist made her a little concerned.

Green Grass, although he was a wonderful stallion with delicious wit and a flirtive manner that had no problem proposing the most outlandish wedding ideas, locked up absolutely cold with the idea of an actual wedding. That’s not to say the two of them had not approached the idea, discussed several elements, considered child names, and compared in-laws, but Twilight considered herself an old-fashioned mare…

No, that was not true. Twilight Sparkle was terrified of marriage too, since she had a bad tendency to think of herself as a child in a world full of grown-ups. Her friends treated her as an adult among her peers, and even a leader, but she kept thinking of every other pony in Equestria as older and wiser than herself, including Princess Celestia, who was older than everypony. The psychological deficiency traced back to when Twilight was a young student in Celestia’s school and a certain colt she was determined to leave unnamed had attempted clumsy intimacy upon her. It seemed like such a minor thing now, but Younger Twilight had tied herself up in mental knots over the event before finally confessing to Princess Celestia.

A number of therapy sessions with Dr. Psyche had resulted. The young colt’s parents moved far away, taking him with them. And Twilight had determined somewhere deep in the back of her mind that no other stallion would ever touch her in that way again.

Touching was certainly not a problem anymore. Twilight and Greenie had touched each other in all kinds of ways lately, some of which she had never even seen in any of her books. Even her language had changed as they had become more intimate. A mere few weeks ago, a cock had been a rooster out at Applejack’s farm, and a pussy was Rarity’s actual cat. Now the crude terms seemed so much easier to say and far more accurate than their technical terms, or at least when the two of them were in close contact. Although that particular linguistic substitution could only go so far, because Twilight constantly broke down in infectious giggles when they had explored the world of creative innuendo involving carrots and cucumbers, and had rolled off the bed in helpless laughter with the names Greenie had proposed for their various bodily parts. Even orgasm had originally been just an abstract word between organized and original in the dictionary, but her first one had exceeded the mere definition, in addition to pulling minor muscles, setting the sheets on fire from unrestrained horn-sparks, and earning more than a few peculiar looks from the neighbors over the next few days.

That’s when she began putting sound-dampening spells up before they fooled around. The backrubs he offered after were nearly as good, and frequently turned into another before, which led to more backrubs, and… Well, some mornings she was so exhausted after their mutual body explorations she could barely write a few notes about the previous night. Particularly when he tried to distract her.

This morning as she caught her breath after their mutual tickling, she was not distracted at all. She was mentally and physically ready, and obviously he was physically ready, but he had made a sincere promise some time prior.

“Fear not, young mare. For although I am a stallion of little willpower, I hereby swear I shall never lay a hoof upon you without securing both your full consent, and the prior written permission of either your parents, or your… um… teacher.”

Over their few months of whirlwind physical contact, they had laid far more than hooves on each other, they just had not gotten laid. She was not about to wait until after they were married, because he was taking forever to get over his phobia about being subjected to a forced marriage by his parents. And admittedly, after digging out Twerps Peerage and looking up some of the mares his parents had tried to pair with him, she had considerable sympathy for his condition.

“Greenie, I’ve been thinking,” said Twilight into the scruffy stallion’s long chest floof. He smelled absolutely divine after their morning wrestling and tickling, which had been started by much the same topic of sex. “No kidding anymore. I really want to do it.”

“Do what?” he responded with a guileless face. “Finish that permission letter to Princess Celestia?”

“No!” She blushed furiously and gave him a nip across the ribs. That letter had been tossed onto her dresser for future disposal. She had started writing it as a way of teasing Greenie, and every word had become less of a joke and more serious, which led to a larger problem. “I’d die of embarrassment if Celestia ever received a letter from me asking her permission for you to have intercourse with me. Besides, it’s not her permission you need, it’s mine, and I hereby give it to you.” She nipped his nose and rubbed her chest up against his belly, feeling the warmth of his rigid cock against her tummy. At one time, she would have been aghast at the sticky sensation against her own belly hairs and in fear of the upcoming burst of ejaculate, but there was a simple solution… actually two simple solutions, but she had done the first several times over the last few weeks, and she was ready for the second, except for one thing.

“Not without a letter of permission,” said Greenie. “Not because of me. It’s for you.”

Twilight rolled over, getting Green Grass on his back and straddling his waist so she could look down at him without rubbing their chests together. That friction certainly did not contribute to her rational thought, and this position did not either, but at least she had a little distance away from his dangerous lips. He, on the other hoof, was very much in range of her more dangerous lips. It took very little shifting of positions to press her soggy pussy against his furry balls and rub just enough to tickle her insides. It was a position she had not been able to maintain for long in the previous times she had tried it, because the sensation of his warm balls and tickling hairs sent short tremors up her insides, and made her absolutely impatient for the more he was willing to give.

“I’m over that vermin,” she started while her hips moved on their own, stroking his damp hairs against her clit with every stroke. “He used me. I trust you. The difference is obvious. There’s nothing about him that is remotely like you except for one thing, and that’s the thing I want inside me. This morning. Now.”

“I promised,” managed Greenie, although he had his eyes closed and was moving his hips in synchronization with hers.

What a wonderful, thoughtful stallion. If only he wasn’t so stubborn.

“I’m releasing you from your promise,” said Twilight, moving up on his body and leaving her own sticky trail up the raised ridge of his sheath. “I want you inside me, thrusting your cock into my pussy until you fill me up with cum. Cock,” she declared, letting the dirty word roll off her tongue in a way that she never would have if the room had not been properly secured by her privacy spell. She would not have trusted anypony else in the entire universe to hear her say it, but she trusted him all the way down to the hungry little tremors in her mareparts. “Cock,” she declared again with every wet stroke. “Cock, cock, cock…”

“Nuglumph,” managed Green Grass. “Letter.”

“I don’t need a letter,” whispered Twilight, feeling a radiant thrill spread through the twitching muscles of her belly. She swirled the damp hairs of her pussy up higher until she was brushing the bottom of his extended erection, and just rubbed up and down the hot length of it for a few precious moments. “You wanted a letter, not me. That’s terribly insensitive of you. I’m a young and hungry mare, who has discovered…” She lowered her voice and leaned forward so she could rest on his unturned chest while rubbing her pert nipples against his balls. “Sex,” she whispered into his twitching ears.

“I’m pretty sure sex was already there,” said Greenie in a husky voice. He raised up off the pillow to kiss her, only for Twilight to pull back and give him a wink.

“Oh, no. You want a kiss, I want something too.” She rubbed back and forth, feeling his thick member roll between their bellies and the additional spot of dampness that was accumulating on her chest. “We’ve tried just about everything else, including some things I never thought I’d like, and a few things I don’t think we’re going to try again. And during all of it, every time you had your tongue up my pussy or I had your cock—” she gave him a brief kiss on his hot lips “—in my mouth, you never asked for permission from anypony but me.”

“True,” admitted Greenie with his eyes still closed and that cute little tremor he got on his upper lip when he was concentrating. “But that’s… different. I want our first time to be special. Nothing between us. No reservations. No fear.”

“You think—” started Twilight as she sat back up again, keeping him pinned to the bed with her legs pressed against his sides and a dripping pussy applied where it was doing the most good “—that I’m going to have second thoughts. That I’ve sucked and licked and nibbled all over your body, and that you’ve done the same to me many times. After all that, after I’ve tasted your ejaculate, and orgasmed dozens of times, and fallen asleep with your nose up my pussy, and that one night that you just couldn’t get me to stop cuming until I got leg cramps.” She moved higher, soaking his hot cock with the outside of her pussy in long, slow strokes that still only went halfway up to the tip. “You think that thrusting that wonderful cock into me and fucking until we can’t move will somehow make me into some simpering mare, running off to Princess Celestia like I was Blueblood’s sister.”

Twilight scooted a little higher until she could feel the furnace-like heat of Greenie’s cockhead against her itchy pussy lips, and the mingled dampness of their juices. Holding one forehoof across her chest, she whined, “Oh, Princess Celestia, it was just terrible. He just kept fucking me and fucking me until cum was dripping down my ass, and then once I sucked him so he was hard again, he fucked me some more.”

Greenie was just so cute when he was giggle-panting, both sexually excited while trying his best not to laugh and failing. “You can’t… That’s… Wait!”

The distraction was only partially successful in gaining her goal. Twilight had scooted far enough forward to feel the hot tip of his cock slip just inside her pussy, and she hunched at the same time Greenie brought his forelegs down and lifted her up so the tiny touch she felt of his wet cock was all she got. It was such an unexpected jolt of pure pleasure that her pussy gave out a short, involuntary spasm of its own, sending shudders of pleasure all over her body and trapping Greenie’s ribcage between her clenched thighs until she could think straight again.

“Do it again,” she gasped. “Only deeper.”

“N-no,” managed Greenie. “I promised.”

After a quick swallow to regain her wits, Twilight put her forehoves onto Greenie’s shoulders and shuddered. “How about… we do like when you first licked my pussy. We do a little, then see how well that goes, and do a little more—”

“By the end of that night, you almost suffocated me,” said Greenie. “You got your thighs around my head so tight I couldn’t breathe. I was afraid you were going to have to write a different letter. Dear Princess Celestia, how do I hide a body?”

“Not nearly as much fun as a permission letter.” Twilight eased back as Greenie let her down until she was resting her squishy self on the base of his delightful cock again. “I don’t see why we can’t just try a little. I mean—” she began running her hooves up and down his chest while rocking forward “—you made me this way. You kissed me, and that was so good…” She squished a little further up his warm cock. “Then you kissed me in other places, and more places, until you got that nosy nose right where it did the most good. I never would have licked your—” she bent down and licked his nose “—cock if you hadn’t driven me so crazy. You made me feel so good that I had to reciprocate, and we’ve gone back and forth, further along in just a few weeks than I ever expected in forever. And I think we’re ready for the next step.”

She knew it was the wrong thing to say the moment the words left her mouth. ‘The next step’ was exactly what he complained about his parents saying when they were pressing for him to marry ‘into a proper unicorn family.’ Those powerful slow-rocking hips beneath her stopped, and she could feel a wave of tension fill his chest. It made her just furious at herself and her big mouth, and more than a little afraid of what would happen to him if someday she did not come back from one of their missions for Princess Celestia.

“I’m sorry,” she managed, only to feel those strong forelegs sweep up her sides, press into her tense shoulder blades, and pull her down against his broad padded chest for a welcome kiss.

“You,” he started between gentle kisses, “have nothing to apologize for. Any clashes between my parents and my own thick head are entirely on me. Although right now at this instant, I could not be happier that I managed to hold them off for this long, because it means I have you.” He gave her a long, determined kiss that left absolutely no doubt that he was giving her his full attention for however long she wanted. It would have been so easy just to remain there, spending hours wrapped around him while her mind calmed in his presence.

She couldn’t.

“I’m afraid,” managed Twilight when she broke for air. She struggled back to a sitting position, scooting back far enough that she was not pressing against his exposed cock, yet not so far that she would squish his balls while they got comfortable. It was one of the lessons she had learned from the adorable teacher, and she had to admit to teaching him several of her own discoveries in the process, but that was not important right now.

“That’s why I made the—” started Greenie, only to be cut off.

“—the promise,” finished Twilight. “I know. You’re afraid too. You’re afraid of marriage, you’re afraid of how powerful I can be, you’re afraid of others controlling your life, and I’m one of the others. And I’m afraid every time Princess Celestia sends me and my friends off on a dangerous mission, I’m afraid I’ll never return, and I’ll fail everybody I lo—”

She froze up on the word, the word neither of them could speak out loud. To admit that word would mean an inevitable checkbox had been crossed out, with huge tracts of unknown beyond. A terrifying, soul-sucking passage into things that could not be checklisted or planned around, where two hearts began to beat as one, and their mingling of souls would create another pony in their image. A tiny pony made of that word, and growing within her body until it became large enough to be born, to eat and poo and read early chapter books, who would look up to her as a mother, and probably destroy the whole world when she screwed up that too…

Though the chill of her fear, Greenie’s warm embrace grew crushing, and he buried his nose into her twitching ear. “Twilight Sparkle never fails,” he breathed. “You only think you’re afraid.”

“I’m not afraid when I’m with my friends,” she blurted out as the tension flowed away in his welcome embrace. “Or when we’re together. Not just like we are now. When we’re having sex, I’m not afraid of anything.”

“Except getting caught having sex with your friends.”

Twilight gasped, and Greenie ran his hooves up her ribs, turning the gasp into a welcome giggle that she stifled into his neck.

“I would never have sex with one of my friends,” she managed between the giggles. “The rest of them would get jealous, and I can’t have sex with all five of them. At once. Unless we made a chart. And a schedule.”

“You’ve got a lot more than five friends,” mumbled Greenie into her neck with a few additional nibbles. “I’m not sharing. We’d need a much larger bed, for starters. The way you keep gaining friends, I’m not sure there’s a bed anywhere big enough. The wedding would be epic, though.”

Twilight released a terribly embarrassing giggle-snort. “You can joke about weddings, but you can’t take one seriously. I can take intercourse seriously, but I can’t joke about sex. What are we going to do with each other?”

Greenie demonstrated with her assistance for a short while, and in a most delightful way, before she pulled away and sat on him again with a quiet and pleasurable squish. “Seriously. Why not?”

“Because you’re afraid of two things,” he responded almost immediately while still running his hooves along her chest. “No, there needs to be a better word for what I’m thinking. After we’re done in bed, I’ll go look it up in your thesaurus. You’re still afraid—” he touched her gently on the chest with the tip of one hoof “—of what that horny little cretin tried to do to you so many years ago. You want to screw me senseless to show yourself that you’re in full control of your body and your mind, which is silly because anypony who spends more than a few minutes around you knows that already.”

“I am not a silly pony,” stated Twilight with the most sincerity she could manage in this position. “But… you’re probably a little right there. I would say it’s about fifteen or twenty down on the list of Why I Want To Have Intercourse With My Sexy Studmuffin. And… I don’t think I would have admitted it if you were not rubbing… ahhh, right there,” she added as Greenie moved his hips in a slow, regular pattern and pressed the prickling base of his sheath against her tingling pussy. “Y-you said two,” she managed after a few long strokes that she suspected were as much cock as she was going to get this morning.

He hesitated before continuing breathlessly. “It’s not impor… Well, it’s important, but I can’t think of how to phrase it without sounding like an egotistical jerk. And I can’t lie to you.”

“But you want to fuck me,” said Twilight, sliding forward again along his rigid cock. “You certainly can’t lie about that. It’s obvious.”

“Why is it we can b-both see what the other is afraid of, and not admit it to our… Um, you better move down a little if I’m expected to talk.” After a quick breath and a little rearrangement, he said in a quick burst, “You’re afraid you’ll lose me if you don’t fuck me.”

“That’s… um…”

Twilight had to stop moving in order to think even a little clearer, although she remained perched on her previous goal. She wanted to keep going, to press her sopping marehood around his cock and hump until the troublesome thoughts all cleared out from her mind, except he had placed one hoof squarely on the exact point she had been evading. Their relationship had grown so fast, like a crystal in a supersaturated solution, which left her with a tiny fleck of fear in the back of her mind that he was just toying with her. Or worse, that she was treating him like some sort of alchemical experiment, and once she had exhausted their potential experiment points, she would toss him aside and write her conclusions in a paper which she then would lock into her bottom desk drawer and never take out again.

It gave her a hollow feeling in the center of her chest that the blazing fire of lust could not touch. Then again, the Forbidden Word kept popping up in her mind whenever she thought those depressing thoughts, the tempting concept of what it would be like to be with him forever, to explore every single facet of his personality and body, to grow old together, to fight and make up, to see their children have children, and to be joined as one in heart and mind with nothing held back…

“Possible,” she managed after some time. “Do you really think so?”

“Yeah.” He ran his forelegs up her back and brought her down onto his chest for some slower hugging. “I’ve seen it at school far too often. One of the frat guys gets all happy that his marefriend is willing to put out all of the sudden, when all of us knew their relationship was going to pot. Then comes the crash, the boom, and the split.”

“So you’re afraid if I do let you screw me senseless,” continued Twilight slowly, “that I’ll leave.”

There was a moment of hesitation, then a nod. “I keep thinking you’ll see me for who I am. A hornless horny fraud. A cheater. A poor student.”

“A thoughtful lover,” said Twilight with a kiss, and continued across his face. “A faithful companion, who likes it when his silly marefriend talks in bed. A fellow bookworm. Somepony who will stand up for me when I want to sit down. Someone who takes away the fear and the tension of life, and replaces it with this roaring fire under my ribs. And eventually, after we work through the correct checklists, a good father.”

“Our kids,” said Greenie during a muffled kiss, “are going to be soooo screwed up.”

“And if I catch one of them in bed with another pony, I’m going to be so hypocritical,” murmured Twilight during the return kiss.

“You’ll be hypocritical?” snorted Greenie. “I will be a raging example of hypocrisy. You will be able to look into the dictionary and see my face as the definition of that word. I will rant so hard my father will look like an example of tranquility and peace by comparison.”

“You will not,” said Twilight with a welcome laugh that loosened the faint lines of tension that had begun to creep up her sides again. “You will be the same adorable squish that every one of your young students have put on their own pillar. And that an older and far wiser one…”

It was either kiss or say the Forbidden Word she could not say, so they decided on the far more pleasurable option. She never finished the sentence, but she did start a new one after they broke for air.

“I’m sorry for pressuring you into intercourse,” she started, “if you’re sorry for pressuring me to write a letter to Princess Celestia asking for permission.”

“Why should either of us be sorry?” He rested one hoof each on either side of her flanks, right over her cutie mark, which was a very ticklish and wriggly spot for her. “Every time you try to get at my body, I get this raging feeling of importance, that you desire me more than anything else in the world. That all those fears you’ve been fighting through your life are less important than us. And someday when you present that letter from your teacher, even that last fear will be conquered by the inestimable Twilight Sparkle.”

She wriggled, despite her best efforts to remain still. “I’m not all that—”

“Yes, you are,” said Greenie, nuzzling her nose. “You are afraid that Princess Celestia still thinks of you as a helpless foal. Do you think she will be angry that you have grown into your own body after you’ve done so much for Equestria? I certainly don’t think so, or I never would have made that promise.”

“Hypocrite.” Twilight poked him gently in the chest. “Let’s take the morning train to Canterlot. We can be standing in front of her by noon, so I can ask her directly.” She managed to keep a straight face for a few seconds before breaking out in giggles. “And we… stop that… can borrow her bedroom… eek!”

It was not exactly an apology, but she still accepted the kisses and mutual touching while returning them in proper proportion until it was Greenie’s turn to break for air, looking deep into her eyes and speaking from the heart.

“When we make love, I want it to be the right time, not the most convenient time, or the most horny time. I want no regrets, no reluctance, no fear at all for either of us. Other than the normal fear of trying something new, I suppose,” he clarified with a soft kiss. “I don’t think we’ll ever get over all of our fears, but we can face them together.”

After some more kissing, Twilight pulled away just far enough to rest her nose on his. “So… Until I’m properly documented, I can still tease you about fucking, rub my pussy against your cock, and do everything except that?”

Greenie wrinkled up his nose. “I would be disappointed if you stopped. It’s a lot of fun, and an incredible ego boost.”

“And we don’t have to stop any other kind of sex, right?” asked Twilight, wriggling back and forth at the touch of his hooves on her rear to feel the press of his rigid cock against her belly.

“I’ve created a monster,” murmured Greenie into her cheek. “Of course we can keep—”

“Good.” Twilight lunged forward and grabbed onto the headboard with her forehooves, then settled down to press her wet pussy against Greenie’s hot cock. “Because this monster is hungry, Spike is making pancakes downstairs, and I can’t walk around town all day with you while dripping. Ahhh, yeahhh. Right there.”

She trailed her tail over Greenie’s balls while settling down down, allowing his cock to press into the crack of her pussy and her convulsive twitches to wedge it deeper. It could not reach inside and tickle the parts she really wanted tickled, but it could and did feel absolutely fantastic on the outside.

“And no fair cranking me up for hours of this,” she panted. “One and done. Pancakes. Oh, stars that’s nice,” she added as Greenie’s cock teased her clit out from its folds and the resulting bolts down her touchy nerves made her grab onto the headboard so hard it creaked. Even if she couldn’t stuff that hot cock up her pussy, she could imagine the feeling of it plunging in and out as his cock rubbed again her clit, and the burst of hot marecum when he gently began to rub her cutie mark on each flank with the tip of his hooves and just…

She had been cranked up so hard to this point that it was far more powerful than any orgasm she had before, to the point where she was really concerned about either breaking Greenie’s ribs with her back legs or tearing the headboard off the bed with her forelegs. She could feel the muscles of his barrel tense in the middle of her convulsions, and his cock jerked rhythmically, spraying hot ejaculate across his upper chest.

At one time in the recent past, Twilight would have been upset about making a mess in the long chest floof of such a snuggleable stallion. That was another fear she had put behind her with the assistance of the mess-maker clutched between her trembling legs.

Well, and an effective cleaning spell afterward.

She held still as the two of them cooled off, fully aware of how sensitive he was after orgasm, yet another lesson she had learned from their mutual educational experiences. It was such a quiet and floating time that she could feel her pulse where they pressed together, two hearts beating as one while their hearts slowed to a normal rhythm. After such a sensitive and intimate time, there should have been some romantic words to trade once they recovered, with gentle touches and affectionate nuzzles. She decided on a different action, before they got carried away and missed pancakes altogether.

“Greenie,” she cautioned after quietly spitting out a small splinter from the headboard, “if you touch my teats, I’m going to nip your nose.” As the gentle hooves moved away from her sensitive groin, she had to add, “After breakfast, and spending some time outside, we’ll come back to bed and keep going. I swear, you’re going to make me bite through the headboard yet.”

“A librarian bookmark,” he said with one long stroke of a hoof down her twitching tummy, adding a dot at the bottom that made her giggle.

“We can’t spend all of our time in bed. A quarter, at most,” she chided him while getting out the tissues and starting a cleaning spell to deal with the pool of ejaculate mostly contained to his furry chest. It was going to be so good when they both got over their respective resistances, and she planned on making good and proper use of every sticky drop internally once that day came. Of course, she would have to write the permission letter to Princess Celestia first, and she was not quite there yet. Nor was she ever under any circumstances willing to write said letter to her own parents, because they would keep it in the family history book, and she would be embarrassed in front of relatives for decades. And her mother might send advice. Cadence certainly would.

“Acting like newlyweds already,” said Greenie with only a slight hesitation from both of them after the word was spoken, and the resulting damping of their mutual warm glow. “That shall wait for later,” he quickly declared. “M’lady hath vanquished yon serpent with the power of her passion, and it already retreats into its lair.”

“You’re just saying that because you want to be in the sequel tonight.” Twilight mopped up a last drip at the ‘lair’ of the serpent, then swooped down to kiss Greenie on the lips. “Come on, up,” she added after rolling off the bed. “Pancakes.”

“Right after you,” said Greenie with a brief grunt to get out of his mattress dent. “I’d follow that happy tail anywhere. Um, dear? You left a little happy there.”

“Got it.” Twilight mopped away some of their mutual moisture with an additional tissue. “What are you going to do if I take this happy tail up the wedding aisle?”

“Check out the rest of you,” chirped Green Grass in a happy trill while shrugging into his vest, “because I might be following the wrong mare, and someday when we wind up there, if we do, I want to be positive.” He took an appreciative look from nose to tail before giving her a long, warm kiss. “Yep, that’s the beautiful mare who captured my heart and totally scrambled all of my long-term goals.”

“I remember long-term goals,” said Twilight with a long sigh and a distant look. “Of course, that was before Nightmare Moon, that Ursa Minor, my friendship studies, and this horney, hat-wearing hunk.” She placed Greenie’s hat firmly on his hornless head and gave it a fashionable tilt.

“If I may be so crude,” said Greenie, leaning closer. “Screw long-term goals.” He kissed her, but drew back when her heart began beating harder and she leaned forward into his lips. “Short-term goals are far better for now. Pancakes. Dealing with our daily tasks. And then…”

Twilight kissed him on the nose. “Reading with you downstairs in the library until closing time.”

He kissed back. “Finding an excuse for Spike to go visit Rarity this evening.”

She smiled. “And maybe, just perhaps, writing the first draft of a letter to—”

He held a hoof over her lips. “Shh. Too long-term. Pancakes are calling.”

And as the two of them strolled downstairs to the library’s cozy kitchenette for breakfast, a lone piece of paper fluttered quietly on top of the dresser drawers. On it was the scribbled permission letter Twilight had been attempting to write as a joke a mere hour ago, barely legible due to the tickling she had been receiving during the process.

Hours later, when the two returned to the bedroom, the letter was long gone.

Neither of them noticed, or paid the slightest bit of attention to the lingering scent of dragonfire.

They had more important things on their minds.

Author's Note

Thankfully, Spike seldom read leftover friendship letters he found around the house before sending them on to Princess Celestia.
