Maud Pie sat in the corner of a third-class carriage of the Friendship Express bound for Ponyville. The past few days had gnawed at her heart. Part of her wanted to hop off the train and gallop back to the rock farm, but she had made her decision. She had to follow through, especially after her first visit to Ponyville.
Maud was no ordinary mare. Once, she had been full of jubilant energy. It bemused her to think that, once upon a time, she had been the happy one of the Pie sisters. But one fateful day, everything changed. She had something her sisters did not: a penis. When she was little, Maud and the others felt it was perfectly natural, but that soon changed when their father, Clyde, had given them “the talk.” That day, Maud learned she was born with an incredibly rare birth defect and was considered abnormal.
She was a futaneighri.
Ever since then, all joy had left her, and she had taken to wearing frocks. All she had left was rocks. They would not judge her. She silently mused on this as the verdant Equestrian landscape rolled by.
One incident from long ago came to mind. She had just hit puberty, and her body was beginning to change. Her phallus had doubled in size and was starting to become active. Pinkie Pie had walked in on her during one such occasion of activity, and Maud had never forgiven herself since. She trained herself to remove emotions from the equation. If she did not feel like other ponies, then perhaps her cock would behave itself.
She despised the thing. At first, she never wanted to touch it, but not doing so left it unsatisfied, making her emotions a lot more difficult to keep in check. After one too many wet dreams that resulted in her waking up covered in horse semen from the chest up, Maud had taken to regularly clopping into a bucket when she was sure nopony was watching.
Maud grumbled as the train hit a bump. She had missed her morning session in order to make the train, and she did not trust the bathroom to provide her with the privacy she needed. She had not done more research than necessary on the subject, but Maud knew that futa ponies were much more sexually potent than ordinary stallions. The number of times she had to pleasure herself daily were evidence of that.
She pulled her frock in close. After seeing Pinkie's friends, she knew she had to do something. Procedures existed to correct her birth defect; with a vagina and no balls, she was like a mare in every way—save for her cock. Ordinarily, it meant a trip to Canterlot or Manehattan in order to undergo correctional surgery, but a sexual health specialist happened to live in Ponyville. She could get the operation immediately.
Although she did not show it, Maud was on the verge of tears. Twilight Sparkle, Fluttershy, Applejack, Rarity, and Rainbow Dash were such great ponies. She wanted to be friends with them so much, especially after what Pinkie told her about them, but as she was, she just could not do it. She wished those mares did not have such fine, young bodies with perky, feminine curves. Even thinking about it made her dick twitch.
At long last, the train ground to a halt at Ponyville Station. Maud disembarked, doing her best to remain inconspicuous. All she had to do was avoid her sister and her friends. She reached into her pocket and rubbed Boulder for good luck as she made her way through the town. She stuck to smaller streets en route to the Ponyville Hospital.
It was almost noon when Maud reached the hospital. She entered through its glass doors and took a seat in the reception area. Without looking, she grabbed the topmost magazine on the table. Who knew how long hospital wait times in Ponyville were? She sighed. By luck of the draw, she had grabbed a copy of Rarity's Secret.
As much as she wanted to put it down, the picture of an attractive mare wearing a harness on the front cover was too tempting to resist. Having a huge cock had the unfortunate side effect of making her attracted to mares just as much as stallions. Perhaps she could find something inside the magazine that she could buy once she no longer needed a dull frock to cover herself.
But instead of looking at clothes, she spent the following two hours gazing hungrily at the pinup mares in the catalogue. Her cock twitched again as blood started to rush into it. Not good. Once she started to get hard as the rocks she adored, there was little chance of stopping. At least this waiting room was deserted, for now. She groaned and stood up, placing the magazine on her back. At least the hospital bathrooms had a lock, and she would have something nice to look at.
“Miss? Can I help you?”
Maud froze. The speaker was directly in front of her. It was one of the nurses. She was a springy young Earth Pony who sported an excellent figure with generous proportions. Her eyes sparkled a brilliant blue, her light pink mane was done up in a bun, and she had a red cross for a cutie mark. Maud nodded at her and discarded the magazine.
“I am Nurse Redheart. How can I be of service?”
Maud mentally cursed. Why did she have to get such a hot nurse when she was in a state like this? Why could it not have been a saggy old nag? “I need to see a doctor.”
Redheart's brow furrowed. “I'd gathered that, Miss. But what for? Who do you need to see? I take it you don't have an appointment.”
Maud tried to look away as her cock grew another couple inches. Before long, it would start to show underneath her frock. “Sexual therapist.”
“For... what, exactly?”
Maud looked into her eyes. “Sexual therapy.”
Redheart cleared her throat. “Erm, well... that would be Doctor Panacea. I can understand that you would wish for this to remain private. Come with me.”
Redheart trotted down a hallway at a decent clip, her hooves clopping gracefully along the linoleum floor. Maud appreciated the view as she followed. Redheart's flank bobbed and swayed as she moved. Maud no longer cared that her cock was still growing. She was about to see the doctor who would be examining it, anyway. What did it matter if it was a little stiff?
They turned a few corners before Redheart eventually came to a stop in front of a door that looked just like the others. She gestured at it. “Right in there, please.”
“Thank you.” Maud turned the knob and entered. This room was unlike anything she imagined she would find in a hospital. It had thick—probably soundproof—walls, a king-size bed, and several large cabinets. It had one door on the opposite end, which opened.
From the doorway stepped what Maud at first thought was an angel. It was a cream-coloured Earth Pony whose beauty put Redheart's to shame. She had a short, purple mane similar to Maud's, but a bit longer and naturally flowing. Her eyes were a radiant purple that matched her mane. She wore a plain white lab coat that clung to her hourglass figure perfectly.
The mare waved in greeting. “Hullo, pony! I take it you are my next patient? I am Doctor Panacea.”
Maud remained still. She could not place Panacea's accent, but her voice was cute and exotic. “My name is Maud. Maud Pie.”
“Ohs? You are related to Pinkie?”
“I'm her older sister.”
Panacea clapped her forehooves together. “Yay! Any relative of Pinkie is a friend of mine! Please, take a seat.” She gestured to the bed. “What seems to be the matter?”
Maud did so, but could not stop staring at Panacea. She was gorgeous; her delicate body radiated beauty. Maud had expected the doctor to be an older mare, but by the looks of it, Panacea looked mid-twenties, about Maud's age. Maud bit her lip as Panacea shut the door behind her and hopped on the bed next to her. The way her body waggled with every movement was threatening to drive Maud wild. Part of her wanted to tear off that cute little lab coat with her teeth and ride her raw.
Panacea gave her a sweet, innocent smile. “So, what seems to be the trouble, Miss Maud? You look quite healthy.” A scowl flashed across her muzzle before her smile returned. “Did some lucky stallion go too rough?”
Maud shook her head. “I do not think I have any problems when it comes to having sex.”
Panacea scratched her head. “Ohs? Then what is it?”
“It's...” Maud reached for the hem of her frock, but hesitated. Her forehoof shook.
“Under there?” Panacea cocked her head, and her eyes bulged. “Ohs...”
Maud's lip trembled. Her cock had grown to about six inches in length, enough to leave a clear impression in her dress. “That.”
Panacea stared at it. “What seems to be the problem? Does it not work properly? We do haves pills for that.”
“It works too well.” Maud leaned back and sighed to the heavens. “I'm a freak, Doctor. I want this thing removed.”
Panacea's ears drooped. “Oh, pony... You are not a freak. You are special. I know of many ponies—mares and stallions—who are happily married to futaneighris!”
Maud stared blankly at her. “Not me, Doctor. I've become one with the rocks I work with so I do not get attached to anypony and get to be alone.” She pulled out her pet rock. “Boulder is the only friend who understands me.”
Panacea gasped. “Does Pinkie not understand you?”
Maud looked to the polished floor. “My family accepts me, or pretends to. But I cannot live like this any longer. I cannot be a real pony as long as I have this enormous phallus attached to me.”
A tinge of pink blossomed on Panacea's cheeks and ear tips. “Ohs! You are huge?”
“Yeah... I have to ejaculate at least four times a day, or else it will get too big to hide in public.”
Panacea frowned at her. “But, Maud, futas are not as taboo as one would think! We live in a civilized society, not the rural areas.”
“Nopony could love me.”
Panacea moved into Maud's field of vision. “That is a lie!” She booped Maud on the snout. “You can so be loved, Missy! I will show you. I refuse to perform life-altering surgery until the patient has fully explored the options. Sex surgery is serious business, pony, and extensive tests must be performed.”
Maud blinked placidly. “What sort of tests?”
“Well, you identify as a mare, yes, yes?”
A nod.
“Good. Being in the wrong body is so very terrible, and I have performed many such operations. But being futa is something different entirely; you are a mare with something extra! Would the patient please remove her garment so the examination can begin?”
A shake of the head.
“There is no need to be embarrassed.” Panacea flared her nostrils and nickered. “One must not be ashamed of one's body. Hmms, perhaps I can make you more comfortable...” Without warning, Panacea stood up and unbuttoned her lab coat. She stood on her hind legs and shrugged, and the uniform slipped off like a droplet of water falling from a leaf. It landed in a bunch at her hooves, and she kicked it to the corner.
Maud could not stop herself from inhaling sharply. Although Panacea's lab coat left little to the imagination, she was even more ravishing with it off. The mark of a stethoscope adorned her generous flanks. Her body was the epitome of fitness; her torso was smooth, and there was not a pound of fat to be found. Panacea batted her eyelashes at her.
Maud's hooves shook as they unclasped her belt. She could not bring herself to lift her frock. Panacea gave her a light peck on the snout and placed her hooves atop Maud's. She guided them to remove the dress. When it reached Maud's head, Panacea flung it to the corner, where it landed neatly on top of her lab coat. She stepped back and looked Maud up and down.
“What a diamond you are!” Panacea ran her hooves along Maud's hard body. “Your condition is excellent, and every facet is perfect. Few mares possess such a figure. You look quite strong.”
Maud shrugged and actually started to blush. “Strong enough to break rocks.”
“That is impressive!” Panacea fixed her gaze on Maud's slowly growing phallus. It was a slightly darker grey than Maud's coat. “All the more reason to not hide away something so gorgeous.”
“I'm not that good-looking. You have the body of a supermodel.” Maud could not believe she just said that. Her face went red.
Panacea covered her muzzle with a forehoof and went as red as Maud. “You are too kind. I merely keep myself fit, just as a good pony should! Now, it is time for your examination.”
Maud shivered. “What is the examination?”
“Before I consent to performing the procedure, you must know what you are giving up.”
“How will I know that?”
Panacea grabbed Maud's cheeks and pulled herself close until their muzzles nearly touched. She wore a perfume that smelled of vanilla. “Like this,” Panacea whispered. She kissed Maud full on the mouth.
Maud was too startled to resist as Panacea's forehooves wrapped around her. It felt like nothing she had ever experienced. Panacea's tongue moved slow and steady, lapping at her own and wriggling inside her mouth. At the same time, Panacea grinded her crotch against Maud's shaft.
Pins and needles tingled over Maud's body. She had never been with another pony like this before, but she could tell Panacea was incredibly skilled. Movements of Panacea's tongue under hers coaxed her into kissing back. Panacea moaned as Maud did her best to move her tongue in rhythm with her lover's.
Without meaning to, Maud placed her forehooves on Panacea's supple flank. Her cock throbbed and grew. There was no stopping it now as it crawled up their bodies. Maud treated herself to a thorough feeling up of Panacea's body. It was soft, firm, and smooth. Eventually, she set her hooves back on Panacea's flank, rubbing and pressing it in time with her movements.
Panacea did the same to her. As Maud's cock neared the end of its impressive length, she bucked her hips into Panacea. Panacea moaned and rubbed her body against Maud's cock. Her pussy tingled with anticipation as her arousal built. Panacea gave her flanks a final squeeze before she broke their kiss and snorted.
Panacea licked her lips and stepped back off the bed. The flesh on Maud's cock had become turgid. The fearsome pillar towered over Panacea. It was thicker than their legs and long enough to go all the way up Maud's torso. A droplet of precum glistened at the top.
Maud looked down at her poner. “I appear to be aroused.”
“Oh, yes, yes!” Panacea approached and sized it up. “What a specimen! I shall have to... 'study' this much more closely.”
Maud did not have to look into her hungry eyes to know what she meant. She laid on her back, her cock arcing over her. Despite its size, it somehow appeared feminine; few veins showed and it was smoother than a stallion's. In a flash, Panacea was on top of her. She wiggled her flank above Maud's face before moving far enough back to tease the flared cock head with her tongue.
Maud bit her lip and groaned. She had given herself fillyatio many times before, but it felt so much better when somepony else did it. Her dick gave a sharp spasm as Panacea continued to lick its edges. She grunted and pushed up with her hips.
“Somepony likes this!” Panacea ran the tip of her forehoof along the hard protrusion. “Remember, pony, if you were not futa, then you could not feel this...” She opened her mouth unbelievably wide and took the entire head in.
Maud did not have to push to coax her partner to take more of it in her mouth. Pleasure wracked her as Panacea's hot mouth and throat wrapped themselves tighter and tighter around inch after inch of huge horny hermaphrodite horse hard-on. Panacea's lips stretched around the medial ring before she stopped swallowing Maud's girthy meat stick.
That was when Panacea placed her shapely flank right over Maud's face and brushed her maregina against her muzzle. Maud had never smelled another mare's mating musk before. She was disappointed. It smelled exactly the same as her own. But that did not stop her from grabbing Panacea's flank and pulling her down onto her muzzle.
Maud buried her face between the soft cushions of Panacea's gorgeous ass and began lapping at her pretty pink petite pony pussy. Panacea responded by humping against Maud's snout while sucking and jerking off the mammoth phallus lodged down her throat, milking every drop of precum it produced. Maud was in complete ecstasy. Maresturbation could not even compare to this experience. She plunged a forehoof into her nethers and began pleasuring herself.
Both mare and stallion hormones flared within her. She was lost in a sea of sexual bliss. It was clear Doctor Panacea was a sexual health specialist for a reason. Her love tunnel tasted amazing as Maud slurped and licked at every bit of it she could find. Every bit of Maud that could be stimulated was stimulated. She reached up, grabbed Panacea's head, and began driving her dick into her mouth as far as it would go, shoving her at the same time.
Panacea made the most adorable little squeaking sounds as Maud rutted her throat. Maud felt a pang of sadness. So this was what she had been missing out on all this time. A burning sensation filled her cock and loins. It was midday, she had not cum since last night, and she had never been more aroused in her entire life. As much as she did not want to, she had to release Doctor Panacea. If she blew her load now, she had no idea how large it would be.
She let go and removed her muzzle from Panacea's dripping maregina. Gasps and pants escaped her mouth as Panacea unstuck herself from her turgid grey behemoth of a horsecock. Panacea's mouth felt so good. Maud tried to restrain herself, but a shock wave of pleasure hit her, and she grunted loudly. As Panacea popped the head out of her mouth, Maud's cock twitched and squirted two generous shots of transparent precum right in the doctor's face.
Panacea spluttered and looked down at Maud with a coy smile. “How naughty! It looks as if you are about ready to explode. But first...” She zipped across the room and opened one of the cabinets. She returned with a tape measure.
“What are you doing?” Maud asked as Panacea extended the measuring tape.
Panacea began measuring Maud's cock. “We keep all peen measurements of mature ponies on record.”
Maud did not question this or protest. She normally could not bear to look at her phallus, so she had never measured. But after making love to Panacea's throat and most likely some of her stomach, she was curious about where she stood compared to stallions.
When Panacea was finished, she let out a delighted whinny and kissed the cock head like a well-behaved younger patient. “My, my, Miss Maud! You have plenty of peen to work with, indeed. It measures twenty and a quarter inches.”
“Is that good?”
She hugged Maud's cock. “Oh, yes, yes! A full six inches bigger than the average stallion. It is most certainly the biggest I have worked with.”
“I take it that is a good thing?”
Panacea nuzzled her shaft. “I do love large peens so very much.”
“Great, but I still need to get off.”
“One moment, pony.” Panacea galloped to the cabinets again and withdrew a beaker. “Will this do?”
Maud sized it up. It was an eighth of a litre. She shook her head. “I usually ejaculate more than that, and this one will be substantial.”
“Okays.” Panacea replaced it with a half-litre beaker. “Better?”
“Bigger, please.”
This time, Panacea produced one that could hold a whole litre.
“Not enough.”
Panacea put it back and scratched her head. “Oh, pony, that is the biggest I've got. But I supposed it is only natural, as futas can cum plenty despite not having visible balls.” She searched the bedroom-like ward. Her eyes lit up, and she trotted toward the metal wastebasket. She emptied its contents of crumpled up paper in the corner, and offered it to Maud. It looked like it could hold about a whole gallon.
“I suppose it will do.”
“Good.” Panacea placed it in front of her. “Would the patient please stand? It will be much quicker and more pleasurable if I can provide assistance.”
Maud wordlessly complied. In a flash, Panacea was behind her and buried her muzzle into Maud's nethers. She whinnied as Panacea's tongue explored her depths. Her marehood clenched and dripped from the stimulation. Her hoof could not hold a candle to the tongue of a skilled mare. Hot ecstasy roiled inside her depths.
Panacea's hooves caressed her firm, shapely flank. Maud stood there and groaned. She wanted to clop, but knew it would be better if she let Panacea work her magic. And work her magic she did. Every nerve ending Maud had down there was aflame with pleasure. Despite being an Earth Pony, there was some serious magic in Panacea's mouth.
Maud's sturdy legs trembled beneath her, threatening to buckle. She was getting close. Panacea seemed to sense this, too, because she slurped harder, faster, and more deeply. Maud rode the razor's edge of her climax. That was when Panacea spanked her incredibly hard. Her hoof rebounded off Maud's hard, muscular flank.
Maud grunted, and her pussy clenched Panacea's snout. Pleasure hit her brain like a tsunami as her marehood came all over Panacea's pretty little face. Maud gasped as she came down. Only precum leaked from her cock. For the first time in her life, she had cum from her mare parts, but not her stallion cock. Panacea was good.
When her marehood started to relax, Panacea resumed her cunnilingus, but this time, she stroked Maud's shaft with her forehooves. Stimulation hit Maud from everywhere. Her nethers were fast approaching another orgasm despite having just had one, and her cock was already close from before.
She could no longer help herself. She leaned forward and placed her own cock in her mouth. Her taste buds loved the salty tang of her precum, which was now being produced in steady globs. Maud sucked harder as Panacea jerked faster. Her cock thickened and grew by a couple more inches as it prepared for its tumultuous release.
Panacea's tongue hit her g-spot, and Maud came. First, she came from her pussy again, detonating a bomb of passion within her. It caused a chain reaction, and her cock came hard. She sucked herself off as the first huge jet of semen blasted forth, exploding inside her mouth. Her cheeks puffed out like a greedy chipmunk's, stretching to the point of pain. She guzzled down the first enormous blast, which nearly filled her stomach with its hot goodness.
Maud popped the head out of her mouth, gagging and spluttering, as the next shot erupted. It discharged like a long, white rope that blasted loudly against the plastic basket. Finally. Relief. Panacea kept jerking, milking her huge cock, which sprayed massive shots that lasted at least five seconds each. Maud's tongue lolled from her mouth as she sent super sticky seed salvos splattering into the wastebasket. Each shot filled her with relief as she emptied herself.
The basket was nearly full by the time Maud's horsegasm subsided. Satisfied, she leaned backward, and Panacea moved out the way to let her sit down. She had never come so much before. Her poner had only partially gone soft. She groaned and rubbed her shaft.
Panacea tied the garbage bag and removed it from the basket. She took a moment to deposit it in her office before she returned. “You were really excited, pony! So, haves you made a decision? Do you truly want to be without your penis?”
“Yes... I have.” Maud cleared her throat and looked into her loving eyes. “I did not know a pony could feel such things. I have not felt so at ease since I was a filly.”
“Of course you haven't,” Panacea said. “Being so sexually pent up is most unhealthy. That ejaculation was really, really hot. There are ponies who would line up to be your sex partner.”
“I can see that now.” She managed to smile. Feeling emotion was so much easier around somepony like Doctor Panacea. She was not put off by Maud's irregularity—she was aroused by it. If such ponies existed... “I think I will stay the way I am. My cock is hard like a rock. I will still have to conceal it with my frock. But you have shown me that ponies can love my cock. And like rocks, I shall love ponies who love my cock.”
Panacea wiped a tear from her eye. “That was beautiful!”
“I write poetry.”
“I can tell!”
Maud leaned forward. “Thank you, Doctor. It will not be easy, but one day, I will be able to find the perfect special somepony. This cock is part of who I am.”
“Then why do you look so glum?”
Maud bit her lip. “Because... you have the best ass I have ever seen. Rock sculptors would be hard-pressed to make something like it. I... I wanted to feel you wrapped around my rock-hard cock, but you are too good. You made me cum too early.”
Panacea stared at Maud's cock. “But you seem ready for another round; you have hardly lost any mass in the peen!”
Maud gave her shaft a slow stroke. Panacea was right. Even though she had discharged nearly a gallon of horse jizz, she still hungered. “I guess you are correct.”
“I haves just the thing!” Panacea turned and dug through yet another cabinet. She produced a long, cylindrical device made of hollow transparent plastic that was about two feet long and a foot wide. One end was open and the other had a strange dome attached to it. A rubber hose connected the dome to what looked like a bicycle pump. A blue rectangle with a yellow cross was emblazoned on the side.
“What is that thing?” Maud asked.
“A penis pump! My own invention.” Panacea affixed the tube to Maud's cock.
The tube was large enough to accommodate her huge member, even in its fully erect state. The padded end of the tube met Maud's crotch, and Panacea started working the pump. A powerful sucking sensation pulled at her member. It felt like millions of tiny hands were tugging at and rubbing her flesh at the same time. Maud let out a long groan as her member reached full mast again almost instantly.
Panacea smiled sweetly and kept pumping. Maud's cock felt incredible. No simple suction could have done this. The pump must have had enchantments of some kind. It felt like her cock was somehow getting bigger as the strange contraption worked its magic. Maud wrapped her hooves around the clear cylinder and rubbed them up and down. The pump was threatening to drive her into a carnal frenzy.
“That will do,” Panacea said as she removed the pump. “How does that feel?”
“It feels like my cock is bigger and harder.”
“It most certainly is!” Panacea gave the twitching member a hungry look. “The magic of the penis pump temporarily increases its size. Before the phallus reaches its climax, it grows larger. The pump emulates such a sensation and stretches it to its true limits.”
Maud stared at her member. It was about three inches longer than usual. On top of what Panacea said her pump did, it also seemed to increase its sensitivity. She closed her eyes and leaned her head back, basking in the heat of her arousal. She was so horny, she felt like even the slightest touch could push her over the edge. This was not the case, as she managed to not blow her stack when she felt something hot and wet touch her broad, flat cock head. Her penis reminded her of a great, marejestic bluff, a pillar of stone tall and cylindrical with a nice, flat mesa at the top.
Her eyes shot open to a face full of bubbly, cream-coloured flank. Panacea grinded her wanting pussy on the top of Maud's shaft, which gave her an inviting squirt of precum. Panacea's back was facing her, providing her with an incredibly sexy sight. Her flanks were right in Maud's face, and her curvy, elegant back showed off a figure that would make trophy wives jealous.
Those fine, stethoscope-branded flanks were just begging to have Maud's powerful, steady forehooves placed on them, so that is exactly what she did. “Hey, Doctor? Are you sure using that penis pump was a good idea? If I am already so big, would making me even bigger just make it impossible for you to fit it in?”
Panacea jerked her head back. “Oh, hush, pony! I ams a trained professional with much experience. I... I want you to insert your tab A into my slot B!”
“What is that supposed to mean?”
Panacea snorted. “Is Ikea romance!”
“As in the furniture company?”
“Yes, yes.” Panacea pressed down harder, but made no progress. “Ikea comes from where I was born.” She grunted and finally managed to pop the head in. A loud whinny tore from her throat as she came, clamping even tighter on Maud's cock.
Maud bit her lip and squeezed Panacea's flanks. Her maregina felt even better than the penis pump. It was so warm, so inviting, so wet, and so, so tight. She leaned forward and kissed those flanks before she buried her muzzle in them and motorboated her. Time was lost on Maud; her world had become Panacea's supple, shapely ass and the feeling of her amazing pussy wrapped around her overly sensitive cock.
Panacea's marehood relaxed around the gargantuan invader as she came down. She panted as she lowered herself on Maud's cock, her rump devouring more and more of the shaft. Maud watched in a combination of awe and pleasure as Panacea absorbed her stallionhood. Thanks to the penis pump, Maud's massive mammoth marvelous mare mating meat mountain was just an inch shy of a full two feet, and yet Panacea was past the halfway mark.
Maud's cock head hit something hard when Panacea was about three-quarters of the way down. Panacea whinnied again and thrashed her limbs around, instantly having another maregasm. Maud realized she must have just hit her cervix. She wrapped her hooves around Panacea's firm, flat stomach and gave her a hug while feeling her up and down.
“Oh... oh, pony! You are huge!” Panacea turned her head back and opened her mouth.
Maud leaned in, and they shared a sloppy kiss as Panacea began to ride. Her movements were slight at first, but became bigger as she adjusted to the huge cock inside her. Their kiss ended as Panacea bobbed up and down. Maud sat still, shuddering with near-horsegasmic pleasure and watching that beautiful creamy flank ride her.
Panacea's nethers formed a perfect envelope around Maud's cock. Maud's insides burned and jolted her with pleasure again and again as the unbelievably tight doctor gave her the ride of her life. She wanted to reciprocate Panacea's hot horny horse humping, but she simply did not know how to. Her mind was awash with ecstasy, her cock ached with stimulation, and she did not possess even the most basic inkling of what to do with her feelings.
She had shut herself off from them for so long, they were completely alien to her. Her cock kept twitching, sending more precum into her lover's snatch. Panacea moved with the grace of an exotic dancer, despite having so much cock inside her. It was the hottest thing Maud had seen, but she remained stock-still.
“Ohs, come on, pony! Do you not like this?”
“Your presence on my poner is greatly enjoyed.”
Panacea turned herself around and looked Maud in the eye. “You have a lot to give. Interhorse is best experience when both partners play an active role, oh yes, yes.”
Maud looked down. “I... do not know how.”
Panacea placed her forehooves on Maud's shoulders and rode her gently. “You poor thing. You are feeling pleasure, yes? I ams creating it by hump. You can hump back.”
“But won't that hurt you?”
“Hmms, perhaps a little.” Panacea winced from reaching her limit down Maud's shaft. “But it will feel very much good. There is a flame burning brightly in that hot body of yours. It speaks to you. What does it say?”
“This.” Maud spanked Panacea as hard as she could. It felt so satisfying to thwack that flank. “Among other things.”
Panacea's tongue lolled from her mouth. “Y-yes! Listen, listen! Give it to Panacea good!”
Adrenaline pulsed in Maud's chest. “Okay, but once I start, I do not think I will be able to stop.”
With a snort, Panacea pushed all her weight forward and kissed Maud passionately. Her tongue thrashed inside Maud's mouth as she humped her a little faster. Maud grinned and kissed back. Something snapped in the back of her mind. Invisible mental fetters that she had created long ago and gotten so used to that she forgot were there snapped like brittle tree branches beneath an avalanche.
Maud snogged Panacea and pushed back, easily overpowering her. She was used to lifting and obliterating massive boulders with her bare hooves, which was what gave her that sexy workhorse physique of hers. She tackled Panacea to the bed and started thrusting her hips, sending her cock slamming into her lover like an immense battering ram.
Panacea was right. This felt a thousand times better. She loved how Panacea fondled and groped her while humping back, moaning and squeaking into her mouth as she was rutted by such a mighty cock. The fire within Maud spread through her whole body. Pressure mounted in her nethers. She broke their kiss, reared up, and whinnied.
Maud's maregina came hard, despite nothing touching it. She bucked her hips and leaned back until her cock was pointing vertically. She was actually lifting Panacea with her cock alone as it shot a burst of precum inside her.
Panacea wrapped her hooves around Maud and whispered, “Now that is more like it!”
Maud crashed down on the bed, landing on all fours, with Panacea pinned beneath her. She shifted her stance until she was firmly rooted in place. The grin on Maud's face broadened when she saw Panacea squirming to no avail. Almost nothing could move her now. She pulled her hips back until her cock was only six inches inside Panacea, and then she buried herself in as far as she could go.
Both mares whinnied, and Panacea's pussy clenched tighter than before. A haze filled Maud's eyes as she drew herself back and thrust again. Exceptional erotic equine ecstasy eroded at her consciousness as she grew used to the odd movements. Soon, her hips moved in a blur, pistoning herself forward and backward with thrusts so powerful they felt like they made the room shake.
Maud's pussy was hot and tingly. Hers—along with Panacea's—was in constant climax. Seeing such a beautiful mare writhe beneath her, her face red and her mane tousled, only turned her on even more, spurring her to hump with every ounce of her considerable strength.
“Oh, you like that, don't you?” Maud said through gritted teeth. “I can probably bore holes in rocks with my dick, and you are taking it. You love being torn in half.”
“M-Maud make g-g-good dom!”
Maud's body trembled. It was not from fatigue. “I think my parents should have named me Cream Pie...”
Panacea cocked her head. “O-ohs?” She let out a loud whinny. “Why is that?”
Maud could only grunt loudly in response. She pulled almost all the way out, then thrust back in as far as she could go. She held it for a few seconds, the repeated the movement several more times, her grunt drawn out over the whole process. With one final thrust, her grunt transformed into a loud bellow, and she came.
Evidence of Maud's love coated Panacea's insides. Panacea's eyes bulged as hot ropes of cum filled her. Maud remembered how much she came last time, and thought it would be a good idea to pull out eventually. She did not want the poor doctor to pop like one of Pinkie's water balloons.
She jerked herself off as she continued to cum inside Panacea, slowly pulling out as shot after shot of sticky love goo filled her lover to the brim. At long last, Maud popped the spurting cock head out of Panacea's pussy just in time to blast her in the face. She grabbed her horsecock with her other forehoof and bucked her hips.
One powerful volley followed its predecessor as she came all over Panacea's face and mane. A spluttering Panacea leaned forward and wrapped her mouth around the gigantic cock head. Maud whinnied and put a forehoof on the back of Panacea's drenched head. Maud stuffed as much of her junk down her lover's throat as she could as she sprayed the remainder of her horsegasm into Panacea's stomach.
Maud, her load finally spent, slumped and fell onto her back, panting. Her cock shrank and slithered back into its innocuous grey sheath, leaving a wet, sticky trail of cum behind on her belly. She looked up at Panacea, who would likely require multiple showers to look presentable again. “Thank you, Doctor.”
Panacea coughed and wiped her face. “It was nothing, pony! One must understand one's body before making such life-altering decisions. I simply provided that understanding.”
Maud smiled, still unable to sit up. She had never been so exhausted post-climax. “This has changed my life. I can live again.”
“Goody! There is a shower in my office. You may use it before you leave. I will need some time to regain the use of my legs.”
Maud staggered to her hooves and rolled off the bed. “Thank you, Doctor Panacea, for everything. I will never forget this.” She walked to the door and opened it as a whole new mare.
Panacea's office greeted Maud's eyes. It was what she would have expected from a typical doctor's office, except there were two significant irregularities: The window on the left was open, and a blushing Nurse Redheart lay spreadeagled on the floor with her hoof in her honey pot.
Maud's eyes bulged. “N-Nurse Redheart?”
“Ohs, no!” came Panacea's voice from the other room. “Not again, you perv!”
