Author's Note

Cred to The Great Derpsby for the name of the procedure, and proofreading as always.

There were some observations and speculations in the comments for the previous chapters on how this while thing could impact pony society in the future, and here I offer one scenario. Do share what you think.

Features: Female masturbation and exhibitionism.

A Possible Future

Tune opened the door, and shot a comforting smile to the two ponies, an earth pony stallion and a unicorn mare, who turned around in their seats to face her. She was dressed in a blouse and a short skirt, with a lab coat over that.

“Good afternoon,” she said in a pleasant voice, and immediately noticed how they took in her figure, which she was very proud of. She was about to tell them that they didn’t need to get up, but it was too late, and she instead extended her hand to them. “Doctor Pleasant Tune. Pleased to meet you.”

“Silk,” the mare said, and shook her hand.

“Strong,” the stallion said, and did the same.

“Please, sit down,” Tune said, and gestured to the chairs they had gotten up from. “I’m sorry for the delay, but somepony wanted my opinion on something just now.”

“It’s no problem,” Silk said.

Tune walked over to the chair behind the desk, swaying her bountiful hips all the while, her bossom jiggling slightly underneath her blouse.

“Now,” Tune said, as she sat down in the chair, facing the ponies. “You are here because you are interested in the Glimcushion-procedure, correct?”

The two ponies glanced at each other, before answering, “Yes,” at the same time.

Tune smiled with genuine happiness. It was always such for a joy for her to provide for her fellow ponies. “Let me first ask you, and do note that I’m under an oath of confidentiality, but you two are a sexually active couple, correct?”

The two ponies smiled abashedly, and nodded.

“Great,” Tune said. “Now, I’m sure you’ve read the information we have in written form, but it can be a hard to get a feel for what the procedure will entail, especially since the practice is still taking hold in the public conscience, so please, ask anything you want.”

Silk and Strong looked at each other again, before looking back at Tune and studying her voluptuous form.

“Do you, uhm,” Silk started. “Have you…?”

“Have you undergone the procedure?” Strong asked.

“I have,” Tune said, and gave them a warm smile. “Underneath this fleshy exterior, I am a rubber sex doll.”

“What’s that like?” Silk asked, eagerly now that Tune had established what she was.

“It’s wonderful,” she said. “I can give you a full demonstration.”

Strong shifted in his seat, and Tune could see a bulge growing from his crotch. He tried hiding it, but Tune just smiled comfortingly at him. “On no need to hide your arousal,” she said. “This is not an inappropriate setting, and I frankly find it flattering.”

Strong looked a bit abashed before nodding and smiling at her.

“How uh, how does it change you?” Strong asked. “Mentally I mean.”

“Well,” Tune said. “First of all, this rumor going around that it’s mind-control is ridiculous. I know of nopony who regrets undergoing the procedure, and I can tell you from personal experience that it has nothing to do with the procedure forcing you to enjoy it, or taking away your individuality. I absolutely love it, simply because it is wonderful.

“The only way it alters your mind is that it enables you to enjoy sex in just about every form, and that includes that it will never grow boring in the least. I can get indescribably pleasure out of just kissing a dildo, and I could spend weeks doing it. It is just a source of endless pleasure.”

“So it’s not true that you barricade yourself in your home and just buck all day long?” Silk asked.

“I’ve done so with other ponies a few times,” Tune said. “But that’s because I could, not because I had to. Again, the rumor that you become a mindless golem is also false, same with the ones that it makes you run around in the streets, exposing yourself and doing lewd acts to fence posts. I am a rubber sex doll and I’m very much a doctor as well.”

“That’s a relief to hear,” Silk said.

“There is one thing though,” Strong said.

“Oh, yeah,” Silk said, suddenly sounding serious again. “We’re interested in having foals.”

Tune shook her head. “Again, you don’t need to worry about exposing the young ones to something they’re not ready for. I have a vast capacity to enjoy sex, but I am not a nymphomaniac. My drive is healthy, and I can keep it hidden around other ponies, and that includes foals.”

The couple was looking more relieved, and intrigued, by the minute. “But you can still have foals, correct?” Strong asked.

Tune smiled at them again, then rose up and walked over to a cabinet, and retrieved a plastic box from it, setting it down on the desk as she took her seat again.

Tune opened the box, and retrieved red-brownish lump of rubber, holding it up in front of the couple.

“This is a standard womb module,” she said. “You insert this into you, currently only works for mares I’m afraid, and you make a foal.”

She tossed it slightly into the air, and it landed on the desk with a smacking sound. “As a mare it stings a little to say this, but it actually functions better than wombs we’re born with. It’s protected, making both it and the little ones inside highly resistant to damage, and you can remove it for extended periods of time without risk to the fetus.”

The couple were looking at the unassumable thing with open curiosity while Tune retrieved another item from the box, a small rubber ball. “This is a standard testicular module. Don’t worry, you’ll still have your balls,” she assured the stallion before he could register the implications. “It’s just that this restores reproductive capabilities in you like a womb module restores it in mares. Again, currently only available for stallions I’m afraid. This mixes in the necessary germ plasm needed to fertilize a womb, either a modular one or one your wife already has in her, by the way the modular womb can be fertilized by either a sex doll or an all flesh stallion. Both units requires a few weeks adjustment period after being installed, during which time it adjusts to your genetic nucleotides. So, any foals conceived by these means will be full flesh and blood, just like you are now, and will definately be yours, with your genes.”

The couple looked impressed at the rundown. “Wow. You’ve thought of everything haven’t you?” Strong said.

“Princess Twilight Sparkle took a personal interest in the subject,” Tune said. “It proceeded very fast after that. Oh, and on thinking of everything.”

Tune retrieved four more items from the box. “Of course, we should not forget these,” she said, holding out what looked like two transparent balloons filled with gel, and two nipples. “Lactation modules,” she said. “These are compatible with both mares and stallions, but I’d recommend only mares using them for foals, for cultural purposes if nothing else.”

“Will uh, will we be able to stay true to each other?” Strong said.

“You mean not having sex with anypony other than each other?” Tune asked, to which Strong and Silk nodded. “Of course. Like I said, you don’t become an unhinged nymphomaniac. My husband and I are both dolls, and sure, we’ve agreed to have group sex and have some adventures and games with others and those are amazing experiences, but I gotta say that there’s something special when it’s just the two of us in front of the fireplace.”

“I think,” Silk said, and took her husband’s hand. “We’re interested, right?”

Strong nodded at his wife, smiling sheepishly.

“Wonderful,” Tune said, and retrieved some forms from her desk drawer, handing them to the ponies. “You’ll need to fill out these. There is a two month waiting period unless you request an emergency procedure. If during this time you should get cold hooves, don’t keep it to yourselves, that’s what the waiting period is for; making sure this is what you want, though nopony has backed out yet, and nopony has regretted it.”

After the couple had read through the not-very-long forms and signed them, they handed the papers back to Tune. “Thank you, and I’m sorry,” Strong said.

“What for?” Tune asked, a bit concerned.

“For… you know,” he said, as he shifted around, trying to keep his bulging erection hidden.

“Oh,” Tune said, happily. “Don’t worry about it. I’m guessing your wife isn’t having entirely chaste thoughts herself.”

Silk smiled into her lap. “No,” she said.

“Half the ponies that come in here I love up anyway, as a demonstration,” Tune said. “Have you tried watching pornography together?”

Silk and Strong nodded a bit hesitantly.

“Did you like that?”

Nods.

“Well then,” Tune said, happily clapping her hands together, and walking over to the door, locking it. “Would you like me to demonstrate some of the things you’d be able to do after the procedure?”

“Uh,” Silk said, and looked questioningly at her husband. “Sure.”

“Excellent,” Tune said, and walked over to the couch in the corner, pulling out a mattress from underneath and turning it into a two-pony bed. “Please, lie down.”

Silk and Strong hesitantly lay down on the bed, and looked a bit nervously at Tune.

“Don’t worry,” Tune said, as she walked over to a closet and pulled out a single mattress of it. “This room is very well isolated, and I have a cleaning-spell on that bed you’re on. Just tell me if you’re not comfortable with anything I’m about to do, and I’ll stop. Now, what do you want to know about sex dolls?”

“Uhm,” Silk started. “Is it true that you can remove parts of yourself?”

“I’m fully modular, yes. Observe,” Tune said, and lay on her side, facing the couple with the same pleasant smile as always. She pulled at her leg, then her other, and they both came loose. She took them in her hands, and held them up by her face as she propped herself up on elbow, her empty skirt falling down, clinging to her empty pelvis. “I can remove all parts of myself, and reattach them just as easily. I can even do this.”

One of Tune’s legs walked in the air in demonstration. “And this is one of the primary sources of joy for me,” she said, and unlatched the belt holding up her skirt. “Being whatever degree of helpless you wish. The illusion is without compare.”

She pulled her skirt off, revealing the shapes that had teased the couple since she had stepped into the door, not wearing any underwear, and her nurse’s cap cutie mark on full display.

Silk and Strong looked on as if spellbound when Tune removed her lower leg beneath the knee from one of the legs, and the hoof from that. “Always so pleasantly warm too,” she said, smilingly, and gently inserted it like a dildo into her marehood. “Ah! Oooooh.”

“Is it, uhm,” Strong started, as he and his wife writhed on the bed. “How, uhm, hard is it attached?”

“Harder than– ah! Harder than a mmmm, flesh and blood pony,” Tune said, as she slowly slid the lower leg in and out of her. “All parts just come off whenever I wish them to.”

“I’ve, ah, heard that you can turn into rubber,” Silk said, as she gently started fingering herself through her skirt.

“Takes your clothes off, dear,” Tune gently told her. “Stain the bed instead.”

“Oh, okay,” Silk said, and the two ponies started removing their clothes.

“To answer your question,” Tune said. “No, I can however remove the outer body that’s fused with the rubber doll I am underneath.”

Tune stopped pleasuring herself with her lower leg, and instead opened up her blouse, letting her large breasts spill out into the open, proud and shapely. By now, Silk and Strong had removed their clothes, liquids slowly coming out of them as they looked at Tune with a mixture of fascination and lust.

Tune smiled to them as she grabbed herself between her breasts, and pulled her skin off like another set of clothes. At first the couple’s eyes were filled with horror, but that quickly passed when they realized that there was no gore or exposed tissue, just a rubber body beneath, and a rubber inside of Tune’s skinsuit.

Tune’s arms lifted her torso out of the skinsuit, which started moving on its own accord, reattaching the legs, then standing up and removing the mask of skin from Tune’s head, taking her mane with it, and putting it in her lab coat’s pocket. Underneath was a perfect copy of the face she had just wore, only rubber, and still smiling gently towards the couple.

“This is how we look like underneath our skinsuits,” she said, as her body turned her over on her belly, pressing her bosom towards the mattress, then went over to the cupboard from before, collecting a crate with a variety of tools, some sex toys, some things others. “I should demonstrate some things first.”

“There’s more?” Strong said, his arousal, and that of his wife, not having had time to wane during the short period of confusion before Tune’s form was revealed.

“Oh yes,” Tune said, as her body set down the crate and retrieved a pink nightstick and a ballgag from it. “We’re still trying to figure out how much physical punishment we can handle, but suffice to say that it’s much. Now please excuse me for a moment, I tend to make pretty loud noises from this.”

Tune eagerly put the large ballgag that her body held out in front of her into her mouth. Her body fastened it, and then took a brutal swing with the nightstick at the back of Tune’s head.

Tune let out a muffled shriek as her head was forced deep into the mattress and bouncing up again, before giggling mirthfully behind her ballgag and looking at the couple with a joyous smile in her eyes.

The body took a few more swings, striking both Tune’s skull and ribs in ways that would be horrific if not for her pleasured shrieks and giggling.

Tune’s body stopped, and removed the ballgag from her mouth. “Mmm,” she moaned. “We can’t feel pain the way most ponies think of it. We can feel a good version of it, sort of like the intensity of something both painful and pleasurable, but without the unpleasantness. Now...”

Silk and Strong’s eyed widened as the headless body inserted both of its hands into Tune’s marehood, stretching it wide and making Tune look down at it with a half-lidded look, moaning weakly.

“Mmm. As you can see, we’re pretty pliant, so don’t worry about the womb-thing. There’s no problem, putting things in and taking things out of there. Also, my chest is one large cavity. I have a pulse, and body heat, but I don’t have any lungs or intestines. I’m just breathing from old habit; I can’t suffocate, and I can eat as much as I want, or nothing at all.”

“Can you… come?” Silk started. “You know, as in…”

“Ejaculate?” Tune offered.

Silk nodded.

“Yes, but I have to intake a liquid to do it with– ah!” she said, as the hands pulled out of her. “Any liquid. I can show you that too. Makes for some great games.”

“What about sleeping?” Strong asked.

“I can do it, and I do sometime. Like I said, there’s something special about me and the mister making love, and sleeping in each others’ embrace can be part of that, but we don’t need to, and a lot of the time we just make love all night instead of sleeping.”

Silk and Strong looked at each other, their faces flushed and their hearts racing.

“What else? Oh yes, notice this cutie mark?” Tune said, and wiggled her loins, showing her cutie mark of a chained heart. “It’s artificial, but I still have all the talents of my real cutie mark–” she nudged her head towards the naked body standing next to her “– the artificial ones can look differently, but they’re all the same; helping us with the great pleasure we can feel as dolls.

“Now,” she said, and looked at the couple. “You two look like you have trouble keeping your hands off each other. I say that you should show each other your love, to make it easier to walk out of the building next to each other if nothing else.”

“We uh,” Silk started. “You’re uh… fine with just the two of us doing it?”

“Of course,” Tune said. “Love is such a beautiful thing to me, whether I witness of experience it.”

“Well I’m ready, love,” Strong said.

“You certainly are,” Silk said, looking down as his member before locking eyes with him.

“I apologize for sounding dismissive,” Tune said, as her body started inserting a plug into her rear. “But– ah! Enjoy your love-making while you can. It’s going to be a very quaint memory in two months.”

“I like the sound of that,” Strong said, before his wife cut him off with a kiss.

Tune bit down on the large ballgag again, and held her eyes closely shut as the vibrators in her marehood and behind buzzed to life.

She looked at the couple as they kissed, panted, and showed their love for each other with touches, hugs, and lickings. She closed her eyes and lost herself in the buzzing of the vibrators, dreaming of her husband as her mind slowly became overwhelmed with pleasure. Less than three hours before they had the weekend to themselves.

As she writhed on the mattress, her cheeks flushed, not from being a limbless, helpless doll who couldn’t think properly from all the carnal pleasure she was feeling in front of a married couple who were ravishing each other in her office, but from the sweet love she was going to shower her husband with in a few hours.

The couple had finally stopped panting, and cleaned themselves off with some wet wipes. In a short while, when their pulse finally died down, they’d look respectable again.

“Thank you again, doctor,” Silk said by the door.

“My pleasure,” she said, assuredly. “I hope to see you again in two months.”

“You will,” Strong said, as they walked out of the door. “Count on it.”

Tune smiled at them, then walked over to her desk.

She caught sight of the picture of her husband on it, and looked at the clock on the wall.

She looked back at the picture, before smiling to herself.

Walking out with a bounce to her step, she joyfully exclaimed that she was leaving early to her colleague, and had to struggle to not skip with joy as she walked home.
