Mature Sex. Berry Punch, OC M/F. Cunt TF (sort of like vore, but cuntier.)

Day 1 14:00

Spectra walked into the office of Doctor Stiffhoof, a specialist in in mare anatomy. As a lesser known side job, he used his knowledge to either treat fetishes, or make a pony’s more wild dreams come true.

“Hi, you’re the doctor I’m supposed to meet?” Spectra asked.

“Yep, Stiffhoof M.D. At least, that’s what it says on the certificate from the University of Phoenix, Equestria.” He gets up and pulls out a chair for her.

“I’m Spectra, I was told you could help a rather unique fetish I have come true.”

“True, you wish to become a part of a pony, a uh—” He opens up a medical chart on the table. “A vagina for a period of three to four weeks in a sexually active pony. Did you bring the payment?”

“Yeah.” She pulls a very heavy sack of bits out of her saddlebags and drops it on the table.

“Good, good. For obvious reasons this will be between you, me, and our volunteer. The spell will be reversed in one month. Our volunteer is a nice mare known as Ms. Punch. Shall we get started?”

Spectra smiled and could feel her arousal growing. She’d been dreaming of this for months, going on years. “Yes, let’s go.”

She followed him out of the doctor’s office and into a patient room. A light violet mare with a richer, dark pink mane was fidgeting on an exam table. Stirrups were pulled out to put her legs on, but so far she remained sitting as normally as she could.

“Spectra, this is Berry Punch. Ms. Punch, this is Spectra,” Stiffhoof said.

“It’s nice to meet you, thanks for doing this!” Spectra cheerfully said. She trot over to shake her hoof.

“Oh, it’s no problem. I’m no saint so I think I can meet enough stallions over the next month to keep ya happy.” Berry finished shaking her hoof, letting out a small hiccup that smelled faintly of red wine.

Spectra was too busy staring at this young mare’s cunt, with no attempt at subtlety. She was going to spend a month as it, after all, and wanted to make sure her fetish worked out perfect.

Berry’s marehood looked a tad loose and well-used, to say the least. It was impeccably clean, however, and she had ever so slightly shortened some of her fur around her pussy to help the labia stand out more. If she lifted her tail even slightly, any stallion within fifty yards would have to be blind to not see her vulva winking at them.

“It looks great, and no offense Berry, but is there a spell to tighten it up a bit? I wanna feel what it’s like to get broken in and stretched wide open.” Spectra offered a smile to Berry, who luckily didn’t look offended.

“If Berry consents, I can do that for you,” the doctor said.

“Go for it! Heck, I’d almost do it for free just to get the ol’ kitty purring again.”

“Well then, if you’re ready it’s quite simple. Berry, put your legs up in the stirrup, and Spectra, hold still while I cast the spell. Then, just push your muzzle against her outer labia and the spell will take care of the rest.”

Spectra nodded, and watched as Berry put her legs up in the stirrups. It spread her hips wide open, and Spectra could see the soft pink flesh beneath Berry’s leathery outer lips. She then realized a thick aura of magic was surrounding her, sending pins and needles through her whole body.

When the spell stopped, she felt lightheaded and empty inside. She realized her breathing had seemed to stop, and her sense of balance was messed up. Stiffhoof was still using his magic to steady her.

“Just step forward and take a good lick of Berry, Spectra.”

Spectra nodded, and tried to say “okay.” However, her rapidly transforming body had already lost its vocal chords.

She leaned forward and buried her muzzle into Berry’s pussy. Spectra moaned as the warm flesh hit her face and seemed to envelop it. She wasn’t sure how the spell would work, but felt her legs starting to shrink. In an attempt to not fall over she tried to pull back from Berry.

Spectra felt the skin of her head fused to Berry’s cunt, sealing her muzzle-first into the pussy. Muscles started contracting, pulling her forward into the waiting pussy. Spectra felt her light body leave the ground as it quickly morphed into the wet slit that would be Berry’s new pussy.

It happened faster and faster, until Spectra tried to blink and instead felt her lips close. Something akin to her tongue, but a thousand times more sensitive, bulged out from between her lips. Spectra realized with great delight she had just winked her—no, Berry’s—pussy.

“Well, Ms. Punch, it worked perfectly! I do hope you enjoy the next month,” Stiffhoof said.

“Thanks! I’ll take good care of her. And she can still see and hear me?” Berry asked.

“Yes, she can. Her sense of sight will really be more of a sense of proprioception—or in layman's terms, more of a sense of what is near to your backside. Effectively, seeing for a foot, maybe two, in front of your marehood. Her nervous system is connected to yours, so she can hear and feel what you feel. In fact, the spell has essentially made her one-hundred percent a part of you, a literal cunt.”

Berry nodded. “Wow, it’s like a dream come true. I’ve always wanted to unbirth somepony and, well, this is as close as I can get.” She chuckled and hopped down onto the floor.

Spectra listened in to the conversation as they continued to talk about her as if she wasn’t there. It was perfect, because in her mind she was not there. She was just a cunt now, a tool for fucking and pleasure. As Berry rubbed her hind legs together, Spectra realized she could also taste everything inside of the wet vagina. It was a salty sweaty taste, more noticeable as the skin of her labia rubbed together.

From her vantage point here she could see some dirt on the tile floor, and Berry’s tail swishing back and forth. She couldn’t make out the wall, but she could see Berry’s back legs and her hooves.

She did her best to relate her new body parts to her old ones. The closest she could figure, her mouth, lips, and tongue had formed the vagina, labia, and clitoris. Her legs seemed bent much further back, splitting in two behind a wide canal. Her own marehood, if it still existed as anything similiar, seemed to be a fleshy wall that must have been Berry’s cervix.

Having gotten her bearing she began to settle into her new home for the next month, when something caught her ear.

“—and the last warning is to get back before her one month contract is up. It’s all she’s paid for, and I’ve never done it for longer than that.”

“Alright, thanks again!” Berry trot out the door and towards the bar for a much needed drink.

Day 1 22:30

Berry giggled as Time Turner bought her another drink. It was her fourth long-island iced tea, and she had already drank Braeburn and Derpy under the table. As the only stallion still conscious, Turner’s odds of getting laid tonight were increasing by the second.

A rather horny, and utterly forgotten, Spectra waited as the two flirted. She had made a wet spot on the wooden chair several inches across. Spectra could taste the dirty chair, it was bitter with some small grains of dirt on it. Her entire body was on fire with a deep aching to be filled, and once again she winked. Everytime she winked, her lips slid across the chair and her clit rubbed against the chair for a tantalizing second.

Berry shifted her weight, looking around and then sending a hoof down to gently rub herself. With nopony paying close attention, she looked down and whispered. “Hey, just a little longer Spectra, and I’ll get you filled up nicely.”

Spectra winked again, attempting to communicate with Berry. Over the last few hours winking had been about the only thing she could do. She’d slowly been gaining more control of some of the nearby muscles, but aside from making her labia twitch, hadn’t learned anything useful. A stream of fluid shot out as Spectra had a small orgasm from her feeling of hopelessness.

“Berry, would you like to take this somewhere more private?”

She looked up at him and smelled the thick scent in the air. Berry realized her passenger was making her normally cock-hungry cunt ten times hungrier. She was spraying pheromones in the air like a school-filly in her first heat. “Yeah, let’s go back to my place.”

Day 1 22:45

Berry took Time Turner into her bedroom and quickly threw away a few empty bottles. They had only been wine coolers, no hard liquor, so she didn’t feel too bad at having left them out. She quickly jumped onto the side of her bed and flicked her tail up.

From Spectra’s vantage point she finally got a better view. With the tail out of the way, she could barely make out the features of a pony’s muzzle closing in on her. A tongue licked at her lips, causing her to wink again. She could see and feel every inch of the tongue sliding up and down her slit, and when she timed it just right and his tongue brushed against her clit the feeling was amazing. Her entire body was electrified.

The taste of saliva mixed with the salty liquids dripping out of Spectra. She could feel the hot breath against her, and each tiny hair vibrating outside her thick outer labia. At long last she saw Turner pull back and climb onto Berry.

The object of Spectra’s desire, a thick, pre-cum dripping horse-cock, came into view. It pushed right up against her lips, parting easily through the slick barrier. The taste of salt got stronger, and also a bit sour, as he slid inside her.

Spectra felt like a sock; her entire body was the band of flesh around Turner’s cock as he slid it in. From here, nearly every nerve she could sense was firing at the same time. She felt like her entire pony body had been wrapped around and around the horsecock, until every single inch was tightly hugging it.

And then he thrust.

She spasmed and winked, her muscles tightening up, as she hugged the cock greedily. Spectra hadn’t expected it to feel this good! She felt like an inflating balloon as he pushed in until her entire body was stretched like a tight condom over his shaft. Then as he pulled out, the friction tugged at her and tried to pull her out along with his cock. He then would push in again, the friction slowly building.

Spectra continued spasming and begging for more. In a way it felt like choking as he thrust in and filled her fuller than she knew was possible. At times she’d feel pressure against the cervix, which at times gave a small wince of pain, and at others a wonderful sense of fullness.

After what seemed like hours, Spectra felt a searing hot pleasure flare inside her. She clenched up harder on the cock as she climaxed. Deep inside her a pressure grew, and soon she could taste the bitter semen filling her up. It was sticky and clung to each inch of her, coating the walls.

After several blissful minutes Turner pulled out. Spectra could feel the cold air inside her as her walls were still gaping slightly. Her stretched out pussy slowly resumed its old shape and size.

Spectra realized after a moment that Berry and Turner were still at it. Berry was giving him a blow job, Spectra could hear his moaning. She could see Berry’s tail moving, and Spectra began to wink again. It was horrible, for her to be sitting here dripping cum and aching for more, while Berry chose to use another hole!

Berry ignored her winking pussy as she had her turn already. it had felt wonderful for Berry, but she was the kind of mare that liked to use all her assets.

After another hour had passed, which felt like a day of starving, Spectra saw Turner mounting Berry again. However, his aim was too high and Spectra felt a pressure on her from above as he penetrated Berry’s ass.

With a mental sigh, Spectra pouted inwardly. Each thrust was rubbing the walls of her pussy together and she could taste the now-cold semen sloshing around. It was still bitter and Spectra would rather be getting fucked then left to taste the sticky fluid for hours. At the same time, just knowing she had no say in the matter was enough to keep her happy and horny. This was exactly what she had always wanted, even if she wasn’t used to not being in control of her own orgasm.

Day 2 11:30

Spectra hardly realized that she had fallen asleep. It seemed that while Berry was asleep, so was she. When she woke up, she felt a rather stiff piece of morning wood prodding against her entrance.

The thick sludge of last night’s cum parted as Turner slowly slid inside for a little morning sex. It was a welcome relief to Spectra, who had gone to bed hornier than she thought possible. This time the bitter taste was well worth it as the familiar rhythm started back up. She welcomed each thrust until finally it was her turn to climax, and bring her owner—Berry—an orgasm. Spectra tensed up and felt her cunt fill up with Turner’s seed.

Content for now, Spectra waited as the two parted ways and Berry hopped into the shower. Thick strands of cum were stuck between Berry’s legs and dripping from Spectra’s lips.

After a moment, Berry laid back and detached the movable shower head. Berry angled it and began to rub Spectra’s lips open, washing out most of the cum trapped inside. She got herself fairly clean, though Spectra could still feel some sticky strands deeper inside. It was the sort of thing she wouldn’t have noticed when she was a mare, but now that her entire world existed within the confines of this cunt, she could feel every tiny detail.

By the time Berry was done, Spectra was already feeling better.

“Oh, yeah!” Berry said. “Hey, Spectra, you enjoy that?” She reached down and rubbed her pussy.

Spectra winked her approval, not picking up on the startled tone of Berry’s voice. The mare had almost forgotten that Spectra was trapped inside her cunt. The spell must have been very good for her to so easily forget such a simple fact. Then again, Spectra hadn’t realized her host would drink so much. She pushed the thoughts aside. Even if Berry forgot, the Doctor wouldn’t. It was silly to think she’d get too drunk to remember Spectra was down here.

Day 5 19:30

Berry had started early tonight, and had already been going for about an hour.

Spectra could discern the slight differences in taste of the cum from the three stallions that’d been spit roasting Berry tonight. The Flim Flam twins and one of their stage-hooves had been in town, and offered to give Berry a wild night.

Right now, Spectra could feel Flam thrusting inside her. He was larger than Flim, and nearly twice as large as their helper. He’d just recovered from a short break and began thrusting into Spectra again.

She could feel Flim, penetrating Berry’s ass, pushing against her skin. Her body felt pinched between the two cocks, and she couldn’t see much other than Flam’s balls. Spectra would have moaned her enjoyment but could only wink, or make nearby muscles contract. Her life as a cunt was rather straightforward and she’d come to enjoy existing in a state of constant arousal and orgasm.

As the pleasure grew Spectra felt the familiar orgasm coming and using her experience, was able to hold it back for a few minutes. It made the pleasure that much better when she finally came and sprayed her marecum all over Flam’s stomach.

Spectra could feel the stallion pull out, nearly a liter of cum from three different stallions packed inside her. The sticky, bitter fluid wasn’t going to drain out for hours. Even then, Spectra would need a good bath to get clean again.

Berry yawned, giving her pussy a quick rub just to let Spectra know she remembered she was there. It was too tiring for Berry to consider a bath now, and she fell asleep.

Spectra got sleepy as well. Before she fell asleep, she felt Flim slid inside her and wear her like a sock. She fell asleep with a thick cock plugging the cum inside, leaving her to taste and smell the bitter fluid all night long.

Day 9 02:30

Berry had been drinking rather excessively. She’d gotten news that her Aunt had died and had decided to mourn the only way she knew how. She hadn’t bothered to speak to Spectra, or take a bath and clean her out well for several days. Spectra knew that a death in the family had to weigh on her and had tried winking over and over to get her attention.

Eventually, Berry had offered her a quick “I know, we’ll bang later.” She had rubbed a hoof against her clit, then forgotten about her again.

Now Spectra sat smushed against a barstool, leaving a slick wet spot on it. Berry was barely staying balanced at this point. It wouldn’t have been so bad for Spectra, except that there was some thick crust on her labia from a recent run-in with Big Mac, who loved to pull out and coat a mare’s backside in cum after sex. He’d made a real mess, and Berry had never bothered to wash it off.

Spectra itched and winked, desperate for a little hygiene. The smell had gotten to where it was like a dozen fish had died inside her. She was stuck tasting and smelling it. When she thought back to it, there hadn’t been a proper shower since the Flim Flam orgy. Part of her wanted to be appalled, but in reality, it just made her hornier. Spectra had always wondered what it’d be like to be another pony’s cunt, helplessly dirty and fucked endlessly. In a way, Berry was making some of her fetishes she’d been afraid to even admit come true.

After itching and winking for nearly an hour, Berry finally slumped over and talked to her. “Heh, I betcha love’t dirty, ya whore. Filthy ol’ cunt fer fuckin’! Haha, well I’m luvin’ it, havin’ my own whore cunt!”

Spectra winked again, feeling arousal drip out of small pours and run down her labia. Berry was really getting into the act, treating her like a smelly old cunt, and it was turning her on.

This fact didn’t escape Berry, who decided to make sure she got fucked good and hard tonight. There was an Earth pony near the back of the bar that looked well-endowed, so Berry went over to hit on him.

After about an hour, even Spectra was feeling the effects of the alcohol. She was sluggish, and felt a bit drowsy. Berry was following the stallion out of the bar, and Spectra was looking forward to a good rutting.

However, not five minutes from the bar Spectra could feel Berry slump down. It took all her focus to discern with her limited senses that Berry was being carried now on the back of the stallion. Spectra wanted to be worried, but with all the alcohol in their system she could barely keep track of her own name.

Day 10 11:45

Spectra had woken up to the sound of chains, and from her vantage point could see a spreader bar pinning Berry’s hind-legs wide open. Berry’s tail had been tied up, out of the way, and Spectra felt a cock slap against her not five seconds later. It forced itself inside before she could get ready.

The cock tasted awful, it was covered in dirt like the stallion hadn’t showered in days. He wasn’t at all deterred by the crusty leftovers of whoever had fucked Berry while the two were passed out.

Now that Spectra was awake, she realized that even though Berry was being raped, it still felt just as amazing for Spectra. The stallion was being a bit rough, yet amidst the pain it brought only more pleasure.

The stallion inside her didn’t have much stamina, shooting his load in only a few minutes. He turned to somepony else in the room. “You two next.”

Spectra wondered where they were, though from the sound they were either in somepony’s basement or a brothel. Another cock slid into her after the first had pulled out, sloshing the cum inside her around.

The bitter taste was forced deeper, and Spectra could feel it dripping through her cervix and being forced deep into her uterus. The stallions seemed to enjoy sloppy seconds, because the second one thrust faster and lasted half as long.

“Fuck, that feels great.”

Spectra winked, a large glob of cum falling onto the floor. A third cock then slid in, causing the pressure to build until the cum from the previous stallions shot out between her folds onto the third stallion’s balls.

“Aww, fuck yeah.”

She tried not to enjoy it, knowing Berry was in danger and probably scared, but Spectra couldn’t hear Berry talking at all and wasn’t sure why. Instead she could do nothing but clench her muscles down as she orgasmed, causing the stallion inside her to spew his hot load inside.

“Okay, get it ready!”

Spectra wondered what they were talking about. As soon as the third stallion pulled out, Spectra felt a thick rubber plug slide inside of her. The lips were pushed aside and her pussy was sealed shut by the intruder. Spectra clenched, trying to push it out, but they’d done something to strap it on. She could feel just a bit of the strap outside of her pussy lips.

She groaned and tried again, but it didn’t help. She felt bloated as several liters of stallion’s cum was trapped inside her. It was still hot and sticky, slowly seeping into her womb, around the plug, and into every fold of skin. Spectra felt like she couldn’t breathe, as the many unpleasant flavors of salt, sour, and bitterness combined.

After a moment she felt something filling up Berry’s ass. Spectra could only tell this from the increased pressure as more was packed inside, then plugged up. She was powerless to do anything as the stallions left her down there for the night.

Day 12 09:30

Spectra still hadn’t heard from Berry. She had figured out she had been gagged, as she could hear mumbling, but there never came a touch to reassure her that Berry remembered she was there. The spreader bar still clinked as she felt Berry being carried somewhere.

After the movement stopped, she heard two ponies negotiating a buying price for Berry. They talked about how she was a common whore they had found, with no family ties, and alcohol problems. To prove his point, one of the stallions pulled the plug out of Spectra.

A thick, putrid sludge began to pour down to the ground in thick strands. Cum several days old leaked out and gave Spectra her first breath of fresh air. Unfortunately, as soon as it had started to leak out, the plug was put back in. The pony buying Berry was angry they had gotten her floor dirty.

Spectra was forced to endure the stench and taste until later that evening, when Berry was unceremoniously hosed down with cold water. Spectra was left to drip dry over the drain, but they hadn’t bothered to wash her out. Instead, they’d just pulled the plug. Now Spectra could taste feces, cum, and urine mixed together as it clogged up the drain and rested against her outter lips. She had never felt so filthy, but at least Berry had a hoof free. Though still gagged, she rubbed Spectra’s lips in a rhythm to reassure her that she hadn’t forgotten.

Day 25 16:30

Spectra moaned mentally as she climaxed, her muscles clenching in a well-practiced fashion. The orgasms were still just as mind-blowing after weeks in the brothel. She was forced to remind herself after every orgasm that she was a pony, because with each orgasm she felt more like a worthless cunt.

She knew the spell was meant to last a month, and believed that at the end of the month, whenever that was, she’d revert to normal. As she was fucked hourly be dozens of clients a day, it was the only hope she had left. If she wasn’t rescued, her life would be nothing but the taste of layer after layer of cum that was never fully cleaned out, and countless orgasms.

Day 32 23:50

Spectra finally got her break. She had lost count of how long she’d been in this brothel. For the past week she couldn’t even keep track of how many ponies had fucked her in an hour. Thinking was getting harder to do, but at least now she had a chance.

Royal Guard ponies were shouting in the basement, rounding up ponies for running an illegal brothel. One of them seemed to recognize Berry Punch as a Ponyville resident, and the abused mare was loaded onto a stretcher.

Spectra knew that now Berry would be able to take her back to the doctor and get her fixed, if it wasn’t too late. She didn’t want to face that possibility, however. As fun as it had been, even when she was dripping load after load out of her lips yesterday, her fetish had to come to an end. She was filthy, hadn’t been cleaned in weeks, and felt like she was with-foal. Something was definitely lodged deep inside her, and it wasn’t a pleasant feeling.

Day 33 09:30

Berry propped her legs upon the stirrups of an exam table. “Okay, Doctor, how bad is it?”

Spectra could feel swabs being stuck inside her and samples taken. “Well, Ms. Punch, you’ve been through a horrible ordeal. Raped countless times, stolen from your home, and sold for sex… I’m so sorry, we’ll do everything in our power to catch them.”

“No, I mean my pussy. I was so worried about it, that they might damage it.”

“Oh, well so far I see nothing wrong with it.” He adjusted his glasses and speculum, then opened up Spectra’s lips to look inside. “Still going to want to take a long, hot bath. Maybe the day spa? It’s a yeast infection waiting to happen in there.”

“Oh, okay. I just feel like I’m forgetting something… is there another doctor that works here?”

Doctor Stable sat back and tapped his chin. “No, though there was a doctor fired three weeks ago for malpractice. Something-hoof was his name, think he’s up in the Canterlot prison now doing hard labor.”

“Oh dear, that’s awful. Well, if I manage to remember what it was I’ll tell you. I just know it’s important for some reason my pussy is okay…”

“Hmm, well let me check something.”

Spectra waited, her proverbial fingers crossed that Berry would tell him she was trapped here. She was so close to rescue, before her fetish dreams became a horrible nightmare.

“Oh! You’re with foal!” Doctor Stable smiled and patted Berry’s belly. “I know the circumstances are not good, but congratulations. Babies can bring enormous comfort to mares.”

“Oh… whew, that must be it. I can’t say I’m happy, but I always wanted a family and I couldn’t possibly think of aborting it! I suppose it’ll be my little blessing from that horrible ideal.”

Doctor Stable nodded. “That’s a very mature outlook, Berry. And, for what it’s worth… here’s a card for the local AA. You survived a month without a drop of alcohol, so I think you can stay sober for the baby easily. A year from now, you’ll deliver a healthy baby!”

“Thanks, so my mare-parts get your stamp of approval?”

He leaned down and gave Spectra one final look. “No tears, no permenant damage, no signs of abnormality. This is a one-hundred percent normal vagina you have. Come back next month for us to check on the baby and we’ll make sure this vagina stays in pristine health!”

Spectra screamed, winking herself at Doctor Stable. She had to get out of here, she wasn’t a normal pussy!

“Oh, I’m so sorry, Doctor.” Berry blushed, taking her legs out of the stirrups.

“It’s nothing I haven’t seen before, and you’re a beautiful mare. If it weren’t for my oaths, I’d probably date you… sorry, I didn’t mean to make it awkward, I just have a brother you might like to meet… sorry, forget I said anything.”

Berry smiled. “No, it’s fine. I’d like to meet somepony and settle down. I think from now on I’ll be a one-stallion mare.”

“Well, I’ll introduce you two tonight.”

Spectra continued to wink, doing her best to scream out for help. The two ponies had entirely forgot she was here, plus she was pregnant, plus each day that passed it seemed harder to focus!

“My… I’ve never seen my pussy wink this much, I’m so embarrassed.”

“It’s a natural reaction to the multiple rapes in the brothel. Your body is used to non-stop sex, you’ll go back to normal in a week or two.”

Spectra stopped winking, knowing it was a lost cause. She began to wonder if she’d spend her entire life as Berry’s cunt.

Then, Spectra realized something horrifying: she couldn’t remember her name, or having ever been a pony. When she thought really hard about it, all she remembered was being an obedient cunt.
