Fluttershy sat on a cloud high above Sweet Apple Acres. From here she could just make out Big Mac and Applejack working in the fields. A warmth flushed through her body as she whimpered softly.
It was the time of year that Fluttershy went into heat, a fact she kept to herself as best she could. There weren’t many stallions in town to help with her problem, and even if there were more, she would still be far too shy to ask one out.
So here she was, spying on the one stallion as shy as her: Big mac. She watched him pulling a yoke and imagining how strong and big his muscles were from all that hard labor. Fluttershy squeezed her thighs together, clenching a tuft of cloud between them.
A blue jay landed on her cloud and began to tweet. He seemed excited and had a lot to say to Fluttershy.
“Oh, really Mr. Blue jay?” She had sent the little birdie to find out what Big Mac liked. The bird and a couple field mice had broken into the house to give Fluttershy a hint on how to approach him and ask him out.
He continued to whistle, recounting his tale of heroism. Apparently Big Mac had left the most interesting thing out in her room: a blow-up sex doll.
“My goodness, I never thought Big Mac was that shy.” Fluttershy pondered it for a moment, realizing she also used toys as a substitute for a relationship when in heat.
The bird continued to tell her how the doll looked well-taken care of. Fluttershy wondered if there was some way she could sneak in and get used like one of his dolls. She spent the next hour fantasizing on the cloud about getting used by him, until not even the slightest hint of horniness remained.
There was a loud thud as Dash landed on the cloud, causing Fluttershy to squeak and bounce slightly. “Hey there, Fluttershy, I didn’t expect to see you napping up here. I’m supposed to clear out all the clouds for the afternoon.”
“Oh, I’m so sorry. I’ll be going so you can do your job.” Fluttershy stood up and smiled.
Dash’s nose wrinkled as she glanced down at the damp spot on the cloud. “Uh, Fluttershy? If you’re in. . .” She paused for a second. Fluttershy was nervous enough when not being propositioned for sex. “If you want me to give you a hoof with your problem, I totally will.”
She blushed, stepping backwards and nearly tumbling off the cloud. “Oh, I couldn’t.”
“Well, I could get AJ, and we’ll set you up with a date with Big Mac. That’s who you were fantasizing about, right?” Dash asked.
“Eeep.” Fluttershy’s cheeks were red as the apples in the orchard beneath her. “That’s-not-necessary-bye-Dash!”
She took flight back towards her cottage, knowing full well she couldn’t out-run Dash. Luckily, Dash didn’t chase after her to recommend the Pony-Sutra or offer to buy her a toy from the Naughty Dragon store on the edge of town.
Fluttershy continued her normal chores to the best of her ability while trying to ignore the burning in her loins. Before she could finish feeding all the animals, she had to take a break and go inside to make tea. Zecora sold her many medicinal herbs, and had one known as icecrown that would take the edge off her horniness.
Inside the pantry she spun a small carousel to find the right herb. When she got to the icecrown, she found the jar was empty. Fluttershy had already gone through a month’s supply this week. She really had it bad this year.
This left her no choice but to visit Zecora for more of the herb.
Fluttershy had hurried down the path to Zecora’s hut. It was actually closer to the cottage than Ponyville was. Once past their initial awkwardness, the two had become close friends. Fluttershy always needed more medicines, herbs, and potions. Zecora often needed the aid of animals to retrieve more difficult reagents, or to warn her if large predators were nearby.
Zecora heard a hoof tapping at her door four times, soft and firm. She opened the door and smiled, knowing it was Fluttershy. “Welcome back, my friend. For what purpose do you attend?”
Fluttershy followed Zecora as she gestured for her to come inside. “It’s so good to see you again. I actually needed some more of a herb that I ran out of.”
“You need only tell me the name, and I will give you more of the same.” She walked over to a nearby cabinet where she kept some of her more popular mixtures.
“I need. . . well, I didn’t realize I had used so much and I’m all out of icecrown.”
The cabinet doors clicked shut as Zecora turned around to address her. “You’ve already used the entire jar? It didn’t get you very far.”
“You know how tough it gets for me every year.”
“You need not spell it out, the topic makes you uncomfortable, no doubt. Yet before I can give more to you I must first ask a question or two.” Zecora pulled out a chair to the nearby table and offered it to Fluttershy.
“Oh, thanks.” She sat down and smiled as Zecora quickly pulled out tea cups and a fresh herbal tea.
“The first concern is about the reason, you use this herb every single season. If used too long to suppress your urges, your sexual desire will become uncontrollable surges.”
“Oh dear, I wouldn’t want that to happen. Maybe just one more jar, and next year I can find a stallion and do things the natural way,” Fluttershy said.
“The herb itself is also addictive, and you’ll need more and more as it gets ineffective. We’ll need to find you an alternative, perhaps something less conservative?” Zecora took a long sip of her tea.
Fluttershy fidgeted a little and decided to try the tea too, in order to buy her time to think of an answer. “I don’t really know any stallions. . .”
“Surely you know one or two, enjoy the tea and think it through.” She smirked and relaxed back into her chair.
“It is delicious tea.” She enjoyed some more of it, finding her inhibitions being slowly lifted. “I mean, I do know Big Mac and he seems really nice. Sometimes I fantasize about—oh my, I don’t know why I’m telling you this.” Fluttershy blushed and drank some more.
Zecora gestured to the tea. “You can speak your mind, you’re safe here. No other pony will overhear.” She left out the part about a mild relaxant she had put in with the tea. It was just enough to help Fluttershy get past her anxiety.
“Well, earlier today I found out that Big Mac has a sex doll. He must be so nervous around mares! And then I thought how wonderful it would be if I. . .” Fluttershy sipped her tea. “Oh my, if I were a plastic toy; Big Mac could use me every night and never have to know. I wouldn’t be scared or shy, I’d just be his special little toy.”
“My herbs prove a cheap substitute for a mare in heat, what will truly cure you is a stallion’s thick m—”
Fluttershy spit out her tea, nearly choking on it as Zecora so bluntly mentioned Big Mac’s dick. She had to shift in her seat and cross her hind legs as her stomach began to burn from her desire. “Zecora I. . .I think I would like that.” Fluttershy tilted her head to the side, nervously hiding her face. “Did I just admit that, out loud?”
“There is no need to be shy, for this is a wish I can help you try.”
“You can turn me into a sex doll?” Fluttershy asked.
Zecora laughed and nodded. “What you ask is not an uncommon thing, many ponies want to give their love life some zing. With extract from herbs, latex, and eucalyptus, plus from my native land a bit of cactus. I have a potion that will make your dream come true, even if you want Big Mac to never know it is you.”
“Oh yes, Zecora. Please, you have to Pinkie Promise not to tell anypony about this. Why, if they found out I wanted to be a sex doll and have—have, oh my. . .” Fluttershy began another bout of blushing.
“Cross my heart and hope to fly, stick a cupcake in my eye. Nopony need know of your secret, the rules of use are not elaborate.”
Fluttershy nodded her head, finishing off the tea.
“First is that it lasts twelve hours per sip, and the change begins on the first drip. Second is it will heighten your desire, turning sex into a roaring fire. When the effect of the potion does end, only then will your desire descend.”
“Okay, that sounds simple enough. Um, how much does it cost?” Fluttershy asked.
“I’ll give you a potion for free, you’ve always been an invaluable help to me. A bottle’s worth should last you for a while, turning you back to normal after each twelve hour trial.”
“Thank you! Oh this is perfect.” Fluttershy got up and hugged Zecora.
Zecora got up and pulled a small box out of a cabinet in her room, handing it over to Fluttershy. “Instructions are included inside for use, but I know a smart mare like you will not turn to abuse.”
“Oh, of course. I’m sure a few nights with Big Mac will make me feel all better.”
“And you’re telling Big Mac of your intentions? There will be no deceptions?”
“Oh, yes! I’ll tell him and be his little dolly, and the two of us will be so happy.” She smiled nervously, not sure if she could actually admit this to Big Mac or not. Maybe after a trial run she would confess her feelings to him. “Well, I better get going.”
Zecora opened up the door and bid her farewell.
Fluttershy had headed straight home and opened the box Zecora gave her. She hadn’t had any icecrown and was feeling incredibly horny. The instructions were quite long and Fluttershy could hardly focus on them. Big Mac would be finishing his chores shortly after sunset, and she was torn between testing the potion out, and visiting him.
There was still half an hour until the sun went down. She went into her pantry until she found a small vial, pouring one dose of the potion into it. Fluttershy would get to Mac’s house early and go for it.
She took only the vial, held snug in her hoof, and flew over to the farm. Applejack was still out collecting apples, and Big Mac seemed to be tending to something in the barn. Fluttershy looked around, and didn’t see any other ponies in sight.
The window to Mac’s room was cracked open and Fluttershy flew down towards it quickly. She managed to come to a stop before ramming into it, then slip inside. The window closed behind her and she began to explore his room.
Mac’s room had a musky odor to it, no doubt why he had been airing it out. Her animal friends had said he kept a sex doll in here but she didn’t see it. Fluttershy went over to the closet and cracked it open. A wide-mouthed pink mare glanced back at her from inside. The eyes were wide and glossy, and the mouth was fixed open in the shape of a circle.
This was it. Fluttershy was about to drink the potion when she thought of something. What would Mac think when a doll just appeared in his room? She hurried over to the bedstand and opened it up, fishing around for a pen and paper. Fluttershy tore a piece of paper out of a journal in the drawer, and wrote a quick note on it.
A gift, take good care of her.
It was simple, to the point, but should keep Mac from thinking too hard about it. Fluttershy then uncorked the vial, downed the contents, and dropped the empty vial into the bedstand.
She walked into the middle of the room and stood there, waiting for the change to happen. Her stomach felt a bit cold, and her throat was going numb. Fluttershy licked her lips, and felt a smooth rubbery finish in their place.
A slippery sensation began to spread from Fluttershy’s hooves. The hairs in her yellow coat began to rustle as the transformation began. She looked down to see her legs smoothing out until the hairs had all melted together. The cold plastic crept up her legs and she felt her bones and muscles softening, beginning to feel like cotton.
She wondered how she would support her weight with plastic legs, then realized the icy pit in her stomach had expanded. Fluttershy’s chest felt hollow and empty, almost like she would float off the ground. Experimentally she tried to stretch her wings out, and instead felt them tug softly. It felt like plastic sleeves had been slid over her wings and fused to her sides.
The plastic had crept up to her neck now, tightening around her skin to straighten it out into the proper posture. Fluttershy felt the plastic touch her marehood and tried to moan in pleasure. Her mouth couldn’t move, the invading plastic flowing over her tongue and down her throat.
Growing pressure inside her love canal snapped her back to attention. Her stomach felt hollow, yet a sleeve of sorts was inflating inside it. Her virgin pussy had re-shaped and opened up into a plastic cylinder, and Fluttershy could almost feel a breeze beneath her tail.
Realizing she hadn’t admired her tail, she tried to look back at it. She could no longer move, managing only to move her eyes to see her mane. It was glossy and pink, with a lovely sheen. Something rubbery had covered her eyes and they snapped back to their position staring straight ahead. She could no longer move them.
Fluttershy realized she couldn’t breathe, or that it felt like it. She felt light-headed and her entire body just seemed empty. None of her muscles responded and she felt as if she were frozen mid-breath.
Assessing her situation she became aware of several things. First, the plastic had invaded her ass too. It must have happened while she was distracted, but she could feel the layers of plastic inside bumping against the sheath for her vagina.
All that remained of her throat was a dead end, surrounded by fake plastic teeth and her slightly-open mouth. Her posture still felt like it had when she was standing, and she regretted she couldn’t see what a good little sex doll she was.
The door opened and Fluttershy felt like jumping in shock. She heard breathing and heavy hooves crossing the floor.
“What in tarnation?” Big Mac asked.
Fluttershy could almost feel his breath on her side, sending shivers through her. The latex coating that replaced her skin seemed very sensitive and she could hardly wait.
He headed over to the bed stand where the note had been folded to catch his attention. He read it and let out a content “eeyup.”
Big Mac turned around and Fluttershy finally got to see his face. He had a goofy grin she found endearing, and his wide eyes showed how impressed he must be.
“Not bad for a custom doll, but I wonder who’d get it for me?”
Not bad? Fluttershy thought. Come on, just hurry up and bang me! I’m just your helpless little toy!
He went over to the closet and pulled out the doll from earlier. “Well, Cindy Cums, looks like I got another doll to break in tonight. Might as well give you a happy ending, though.”
Fluttershy wondered why he was talking to her as if she was real. That slut has such a stupid name.
Big Mac carried the other fake sex doll over to his bed, squirting something onto the doll and his own dick. He slid inside Cindy’s pussy and began to pump forward.
What the hay? Big Mac, I’m right here! Why are you banging the wrong doll!
“Eeyup, but I have room for two dollies in my life, Cindy. After I break the new mare in we’ll go again.”
He’s. . . not quite right in the head. Fluttershy watched him bang the doll, and felt her marehood warming up. The plastic seemed to spasm slightly and began to tingle. It was worse than an itch, almost like when her hoof fell asleep and started to wake up. Fluttershy was helpless as she watched Big Mac bang the other doll, her sex feeling pin pricks and needles through it. Dammit! You need to buck me!
Big Mac finally slowed down and pulled out, leaking a long strand of cum to the floor. He pulled out some paper towels from the bottom drawer of the bedstands and wiped the doll down. Then, he pulled the plug and let it deflate.
“Better put you away for now, I think I’ll sleep with Fuck-me Flutters over there tonight,” Mac explained to Cindy.
Fuck-me Flutters! Oh, my. . . it’s perfect! Come on, Fuck me! Fluttershy put all her effort into pouncing on Mac, but was trapped immobile in her plastic shell. Come on! Come on! She had never felt this horny, this ready to be used.
Big Mac began to walk around the Fluttershy doll, stopping in front of her. “You’ve got a pretty face, but the mouth isn’t the right shape. Let’s see if it feels as good as it looks.”
Fluttershy tried to lick her lips in excitement, giggling mentally as she realized toys didn’t lick their lips. She was truly going to be fucked senseless as little more than a toy.
Mac’s head was still covered in his semen from earlier as he slid it into Fluttershy’s crescent shaped lips. She was surprised to taste it, though she didn’t know how. As the head pushed past her fake tongue, it straightened out the cum-sleeve that was her throat.
Her head was forced down and her squishy body bent forward as Mac straightened her out to fuck her in the mouth. Mac was pleased that the plastic wasn’t wrinkled and rough inside, showing the doll had some quality.
Fluttershy felt waves of vibrations pass over her skin, and the air inside her heating up as an orgasm built. Mac was only in her mouth, yet she could feel every inch of her plastic throat sliding along his thick shaft. Mac bottomed out in her and Fluttershy felt her body get rocked back and forth as he thrust in and out.
With the large shaft inside her mouth she felt the familiar sensation of being short of breath. Then she felt Mac’s hooves, squeezing around her neck. Fluttershy felt as her neck was constricted until Mac was grabbing his own dick. He began to use his hooves to rub his cock as he thrust in and out, twisting Fluttershy’s neck in impossible directions.
She could feel her skin and her throat touching, and the electric tingle building inside. The heat from Mac’s body pushed her over the edge, bringing on her first orgasm. She couldn’t move an inch, which heightened the orgasm immensely. Her entire body wanted to writhe in pleasure, but was stuck as still as a statue as the thick shaft continued to build friction in her mouth.
Finally, she felt a large bulge travel down Mac’s cock, spraying out into the back of her throat. Load after load landed in the sleeve as he continued to rub his shaft. Mac squeezed her head and gave it one last thrust. Fluttershy felt her flanks stretch slightly from the increased air pressure.
Fluttershy felt him pulling out, coming again as Mac let go of her neck. The orgasm felt so different than when she was alone in her bathtub. These ones lingered, running over her skin like ants. They seemed to build and build, nearly driving her mad. Yet the sensation of having Big Mac break free of her mouth was the worst. She felt so worthless and empty without him inside her: a toy with no purpose.
Several loads of his cum shot onto her face, covering her eyes and dripping into the small holes that formed her nose. Fluttershy could still feel her throat resting against her skin, weighed down by all the cum. The sleeve felt nearly full.
“Whew, not a very good sex doll, but somepony put a lot of thought into it for me. I suppose I should keep it around in case they ask if I liked it.”
Fluttershy couldn’t see him, due to the cum coating her eyes. She heard Mac yawning and climbing into bed. What does he mean not very good? I thought this was his fantasy, to have a realistic sex doll. Maybe they’re just worthless toys to him? No. It felt amazing to me. I just need to find a way to make it better, to make him love me more.
A soft snoring sound caught her off-guard. She had lost track of time, unable to see and with the salty taste of cum lingering in her mouth. He didn’t even clean me up like he did with the other sex doll. Maybe I’m not good enough. . .
She continued to think about what she did wrong all night, unable to move or satisfy the burning in her loins. As amazing as the orgasm had been, it only lasted until Mac was no longer touching her. I need him to touch me, to use me. He can’t discard me, he needs to use me every night, all the time! Oh, I have to make this right.
Fluttershy felt an itching along her skin. Something seemed to twitch, and she started to pay careful attention to the sensation. It crept up her legs until they felt solid again, weighed down and warm.
She moved a hoof tentatively, and felt it respond. The itching continued as the plastic turned to hair along her backside. Fluttershy felt dampness running down her legs as her marehood, tortured by twelve hours of not being used, dripped down her thigh.
A burning sensation in her chest made her gasp in for air. She gulped down the cum in her throat as her stomach returned, nearly spitting it up. Fluttershy was drooling, cum dripping down her throat, and the thick scent of it burning her lungs. It was even in her nose as she had inhaled.
Blinking, she felt her stinging eyes fighting the slightly-crusty cum. She reached up and wiped her eyelids off, shaking her head to try and clear her vision. After a moment, she found herself breathing heavily and turned back to normal.
Mac was nowhere to be found. Fluttershy went over to the window, and saw him out working the field. He hadn’t even bothered to put her away or clean her up in the morning. Maybe he had over-slept.
Fluttershy had planned to get used by him and then sneak out, just like this. The farm pony only slept seven hours a night, leaving her plenty of time to show up before he went to bed and leave after he woke up. Yet, she had expected so much more from him.
She snuck out of the house, flying high into the air before heading towards the cottage.
Fluttershy spent most of the day in her bath tub, reliving the previous evening. It had felt great for her, yet hadn’t made Big Mac happy. She wanted to be his perfect dolly, to get used and cuddled and loved.
The potion and the instructions that came with it offered her some hope. It listed that doubling the dose would make the transformation more realistic. The effects would still last twelve hours, but she should find small changes. Fluttershy wondered what they were, and continued reading.
As the sun started to set she realized how little time she had left to get ready. She prepared the double dose of potion and raced across the sky to Big Mac’s room.
She found the window open again and flew in. Mac probably hadn’t even known she had left. Fluttershy swallowed the dose of potion and took her place in the center of the room. This time she faced a vanity mirror to watch the transformation.
Once calm, and her legs unable to move, she felt her lips hardening. She tried to close them and swallow, but they had been fused into a solid round ring. Looking in the mirror revealed a bright red ring, the perfect shape for sucking a dick, where her mouth had been. Her teeth and tongue were much smaller, tucked out of the way.
Eyeliner and beautiful painted on eyebrows adorned her face. She marveled at how shiny and smooth she was now.
Her hind quarters seemed to stretch widely apart. A familiar ring sensation in her marehood let her know that it too had been turned into a perfect fuck hole. Moments later, her anus puckered open too.
This is perfect! I’m sure he’ll love me now!
Just in time she had turned back into a doll, because Big Mac came through the door.
Big Mac walked around in front of Fluttershy. “Who cleaned you up? I hope AJ didn’t find you. I doubt Granny would. . . hmm, or maybe I had a little too much cider at dinner last night. I don’t remember you having this lovely red lips, Fuck-me Fluttershy.”
She squee’d mentally, so happy that Big Mac approved of her now. Yes, screw me now! I’m your little toy to be used! The heat that had been bothering her for two weeks seemed to intensify, as she thought more and more about having him deep inside her.
“Well, I do appreciate having such a beautiful new dolly in my collection.” Big Mac kissed her on the cheek. “Why don’t I break you in properly now?”
Oh yes, this is perfect! Fluttershy couldn’t wait, and luckily she didn’t have to. Big Mac nudged her in the side, causing her to sail through the air towards the bed. She bounced off it, landing on her side. The cool wooden floor on the ground pressed against her side.
Mac then lifted her up and pushed her against the bed. Fluttershy’s neck buckled, full of air and soft as paper. The rubbery face of Fluttershy was now glancing between her own hind legs.
From this angle, Fluttershy could see Mac’s cock extending out of its sheath. Mac seemed content to keep her like this, pinned up against the bed and bent in half.
“This gives me an idea.” Big Mac put on his lubricant and lined up his cock and her gaping pussy-hole. The tightness of the ring against his shaft was a welcome sensation to them both. He continued to push in until her rubbery-canal had taken in his full length.
Fluttershy was in heaven, enjoying every second of the plastic stretching to accommodate Mac’s dick. The plastic seemed to stick to him, warming up from the friction and becoming the only sensation that mattered to her.
She then saw Big Mac’s hoof, and felt his balls slap against her face. Each testicle was nearly the size of her mouth, and she watched in surprise as he pushed one in. Fluttershy felt the bulge pass the O-ring that was her lips. Pressure continued to build, and she could see a hoof maneuvering the other testicle.
Finally, the second nut popped into her mouth. The tight ring sealing around them, trapping them inside. Fluttershy wished she could moan and suckle on them, keeping them prisoner in her mouth.
Mac was happy with his creativity and began to slide in and out of Fluttershy’s pussy, letting the friction build slowly. He brushed her tail out of the way, and pinned her wings to the bed.
Fluttershy felt so many sensations at once, each one ten times as intense as she felt as a pony. First were her wings, the air pushed out of them as Mac pinned them flat against the bed for leverage. Each thrust tugged against the base, creating the most wonderful sensation of stretching and pleasure.
While her wings were stimulated, her mouth was tugged forward, straining her neck. Her lips had sealed around his balls, and with each thrust she was pulled along for the ride. Fluttershy imagined it was a fluffy, warm gag that had been stuffed into her mouth. The slight stretching stimulating her, and the motion allowing her to get a clear view of Mac’s muscular legs as he thrust in and out.
The main event was in her pussy, where Fluttershy felt the most incredible sensation of tightness. Her plastic sleeve of a marehood was smaller than Mac’s shaft. This caused it to stretch with each thrust, giving them both a wonderful sensation. For him, it built the pressure and friction. For Fluttershy, it was like taking a deep breath until her lungs had filled all the way up. The stretching and expansion of it felt ten times larger than her hoof in the shower.
She continued to be contorted and fucked against the side of the bed. Mac was getting really into it, increasing his speed until Fluttershy’s head and belly were rubbing together hard enough to squeak. Fluttershy could barely keep track of the thrusts. All of the air inside her seemed to have caught fire, blazing every nerve in her plastic skin.
The pressure continued to build inside Fluttershy, exploding into the most wonderful orgasm she had ever experienced. Every light touch was amplified as her balled-up form was fucked senseless. She began to drift off into unconsciousness, unable to keep up with the over-stimulation.
Fluttershy felt Mac’s balls tug, one of them popping out of her mouth, and bringing her back to reality. A second later, a load of cum filled up her pussy. The plastic sleeve began to make a slurping sound as Mac pumped more and more semen into it, and continued fucking.
The pressurized lube started to spill out, running down Mac’s shaft and dribbling into Fluttershy’s mouth. She lost control of her building orgasm again, extending the one from earlier. Once again it threatened to overload her senses and make her pass out. Something about her plastic body kept her from passing out, however, and she was powerless to resist the raging inferno in her belly.
Mac still hadn’t lost steam. He pulled back, letting Fluttershy spring back to her normal pose of a sex doll. As his tip cleared the ring of her pussy, a torrent of cum splashed out. Still in a haze from the sex, Fluttershy felt the emptiness and overwhelming sadness. She wanted more, and didn’t want it to be over.
Fluttershy nearly exploded into a third orgasm as pressure built against her anus. The cum-covered head of Mac’s flared penis slid past the smaller, tighter ring and into Fluttershy’s ass. The sleeve here was smaller than the others, tightly hugging his dick.
Pressure and warmth continued to build as Mac repositioned, thrusting with abandon into her ass. This time Fluttershy could feel the bump of the medial ring as it passed her anus, and the rapidly expanding plastic sleeve.
With each violent thrust, Mac caused more of the sperm to drip out of Fluttershy’s cunt. He was beating against Fluttershy so hard that she thought he might pop her, yet the feeling was so incredible she couldn’t even think of stopping.
Fluttershy’s fourth orgasm hit during her haze, barely registering that it was a new orgasm and not just a continuation of the first. The sex-doll potion had turned her into a non-stop pleasure machine.
There was a coarse feeling as Mac wiped off the cum coating her backside, then a small string from her lips. Satisfied she was clean enough, Mac tossed down his covers and slid Fluttershy into bed.
The warm blanket covered Fluttershy up to her head, and Mac pulled her tightly against his chest. “Whew, that was good. Not as good as Blow-up Berry, but better than Cindy-Cums.”
Fluttershy began to wonder how many sex dolls Big Mac owned. She was happy that she was better, and her orgasm had been much better than last night, but she still wanted more. It still wasn’t quite perfect. Close, but not perfect.
Mac squeezed her tightly, burying her face in the hair below his neck. Fluttershy listened as he fell asleep, wrapped around her. Each tiny movement from his legs rubbing against her skin electrified her, as if teasing an orgasm that never came. However, Fluttershy found a contentedness in it. As long as he was touching her, using her, Fluttershy knew everything was perfectly fine.
Fluttershy snuck out the next morning, hurrying back to her house. This time when she took a bath, she had no desire to masturbate. It was as if her heat had passed, and no hoof-job or toy would be half as good as what she had shared with Mac.
There was still a mental desire there. Though her marehood had calmed down, Fluttershy wanted at least one more night with Big Mac before putting the potion away until next year.
According to the instructions, the only way to please her stallion, Big Mac, was to take four times the dose. At this dose, the instructions stated that ‘the user will be indistinguishable from a normal doll.’ Fluttershy figured that being the perfect doll for twelve hours would certainly make Mac happy.
Fluttershy took the quadruple dose and a note she had already written over to Mac’s house, excited for one last fling. Surely, it would feel twice as good as last night had.
After sneaking into his room she left the small note on the night stand.
I improved your gift, -secret admirer.
It was simple, short, and written plainly. It would explain to Big Mac why his toy kept ‘improving’, in case he had any suspicions.
Without hesitating, Fluttershy drank the potion, then tossed the bottle into the trash. She tried to get back on the bed, where Mac had left her last night, but her hooves weren’t working right.
The change was happening much more quickly this time around, and her inside already felt light as air. She hadn’t expected it to be so quick, yet this was her third night in a row so she was used to it.
Her flanks seemed to expand a little bit, becoming rounder and fuller. Beneath her thighs, her two tits formed round balls and grew larger. Fluttershy was a bit shocked as her proportions changed into those of a true sex doll. Her waist even narrowed slightly. Next was her neck thinning, her hair lengthening, and her face reshaping until it had perfect features.
Fluttershy really wished she could see herself and how amazing she looked. There was an odd sensation like someone was tracing along her body with a pencil. It traced down her spine to her ass and marehood, then around her belly and up her neck. Fluttershy realized it seemed to be dividing her in half, realizing it must be a seam.
Several more seams formed, running down her legs, around her wings, and ears. They had truly made her indistinguishable from an ordinary sex doll. Something bulged on her flank, and she felt a popping sensation as something pushed out of it. Fluttershy wondered what the bump on her flank could possibly be, but couldn’t turn around to see.
The door opened and she heard Big Mac gasp. He walked over to the night stand, seeing the note. “Wow, it really does look perfect this time,” Mac said. He tossed the note in the trash and walked over to feel her.
His hoof traced along her cutie mark. The latex was almost frictionless, and as he pushed the polished surface it gave slightly. It seemed sturdy and of very high quality. Mac lifted up her tail and looked at her marehood, sticking a hoof in it.
Fluttershy felt him probing her wet pussy, then wondered why it was wet. Little did she know, it was now pre-lubricated, courtesy of the potion.
Mac marveled at her soft insides, somehow already wet and ready. “This’ll have to be the best sex doll ever, I’m just gonna—”
“Big Mac!” Applejack shouted. “What in tarnation!?”
Fluttershy tried to scream in fear and scurry away, before recalling she was just a toy for the next eleven and a half hours.
“Sis, I can explain!”
“No! I told you not to keep those in the house.” She walked in and closed the door. “Look, you have the room in the apple cellar for this stuff. I thought I saw you sneaking a doll in a few days ago.”
“Come on, I don’t get much sleep as-is. I don’t want to go to my dollhouse in the apple cellar each time I want to have sex.”
“Listen to yourself,” Applejack scolded. “Look, I know it’s tough, I just can’t risk Apple Bloom seeing this. She’s too young, and you left the door open. Look, you go down there and pick out one of your other dolls for tonight. I’ll fold this up and put it on the top shelf of your closet. Take it down with the others after Apple Bloom is in school.”
“Okay, sis.” Big Mac walked away, leaving a puzzled Fluttershy in the middle of the room.
Wait, what’s she mean folded up? I’m not a real sex doll. Fluttershy tried to warn Applejack, but couldn’t move. Moments later Fluttershy felt something bite against her flank and tug.
There was a hissing sound, and Fluttershy began to feel lighter. She panicked as her very life seemed to flow out of her, terrifying her.
Applejack nudged the Fluttershy doll onto its side. “Can’t believe he had one made of Fluttershy, this is ten kinds of creepy.”
Fluttershy felt two hooves squishing her side, and felt her right and left flanks touching. The air rushed out leaving her feeling dizzy and light-headed. Applejack continued working the air out, pancaking Fluttershy between the floor and her hooves.
The flat feeling passing through her body felt wrong on many levels. For starters, she could feel every inch of her outside on the inside. When Applejack folded her neck and pushed her head against her flank, Fluttershy could feel her cutie mark with her lips.
Next, her four limp legs were folded up onto her side. Then, her chest was folded in half. Fluttershy’s right foreleg was now touching her right hind leg, which touched her right cheek and nose, which was pushed against her left flank, which pushed against her tail, which was pinned to the ground.
Just trying to picture herself being folded into a square sent Fluttershy into uncontrolled panic. She got smaller and smaller as Applejack carefully folded her up. Fluttershy felt her entire form pressing together into a square less than two hooves wide.
Applejack’s lips bit onto Fluttershy, pushing against her left ear and left flank. She lifted her up and quickly slid her onto a shelf in the closet. Applejack then set down a box of photos on top of Fluttershy, flattening her.
It was very dark now, and Fluttershy’s eyes were folded up somewhere in her middle. She felt the weight of the box on top of her, forcing a little more air out and concealing her from the outside world.
She wanted more than anything to scream, yet her mouth didn’t work. She was stuck here now for twelve hours. That was when Fluttershy came to her second realization: would she turn back to normal, all bent up like this?
Fluttershy couldn’t do anything but panic, hoping Big Mac came back soon. She regretted this whole stupid idea, trying to fight the growing sense of contentment in her mind. A voice in Fluttershy’s head was telling her this was a good thing, that a toy belonged folded up on the shelf when not in use. She did her best to ignore it, while she waited for rescue.
Applejack and Big Mac were busy in the fields when Twilight stopped by. Applejack came over to greet her. “Hey, please tell me you have good news.”
“Not yet,” Twilight said. “Fluttershy has been missing for three days now.”
“There must be something we can do.”
“Well, we checked her house and Zecora on the first day. If she’d gone to Cloudsdale, even a weak flier would have made it in two. The police only start searching on the third day. . .” Twilight sighed. “Unless you have any thoughts or leads, however small. I mean, a pony doesn’t just disappear completely!”
“Well there was—nah, it couldn’t be, not Mac,” Applejack stated.
“What do you mean? If you know anything, Applejack, please tell me.”
“It’s gonna sound crazy, I think showing you would be easier than explaining. Follow me.” Applejack trotted off towards the house, with Twilight following her.
“What’s this about?”
Applejack remained silent, leading Twilight up to Big Mac’s room. Once they were inside, Applejack closed the door. “You need to keep this a secret, it’d embarrass Big Mac something awful.”
“I promise, what is it?”
“Well, he’s got this thing for dolls. . . sex dolls, and the night before we all noticed Fluttershy missing, I caught him in here with a sex doll that looked just like her,” Applejack explained.
Fluttershy could hear their voices, worried that she was imagining them and had started to go insane. She hadn’t been able to keep track of time and Big Mac hadn’t raced back to valiantly save her. She felt so worthless. A good sex doll would be getting used right now, not forgotten about in a closet.
“Right up there,” Applejack said.
Twilight levitated the box aside, then levitated Fluttershy down. “Wow, you weren’t kidding.” She stretched the toy out until it hung limply, giving a profile view of the yellow pegasus.
“You don’t think, somehow, that’s Fluttershy?”
Yes, it’s me! Fluttershy cried. She could feel the magic tingling around her skin, holding her gently and firm.
“Let me see.” Twilight closed her eyes and focused. After a minute, she opened her eyes and shook her head. “Nope, this is just a normal, albeit very disturbing, sex doll of Fluttershy. If this doll was some sort of spell, I could sense it.”
It’s not a spell, it’s a potion! Please, Twilight! Fluttershy continued to plead, begging her to rescue her.
Twilight folded her slopily and set her on the floor of the closet. “Mac doesn’t have ones of the rest of us, does he? That’s not okay.”
“Of course not! Listen, Twi, Mac hasn’t told a single pony about this. He’s mighty shy around mares and well, just don’t tell anypony about it, okay?”
“Alright, in that case I better get back to town. We’re going to visit Canterlot again, just in case she went there for some reason,” Twilight said.
“Sounds good, I better ring the dinner bell and get everypony ready for bed,” Applejack replied.
Fluttershy had landed on her side, now crumpled in the closet on top of a dirty towel and mane comb. She could see her friends, just a few feet away, but was powerless to reach out to them.
They left her there, and Fluttershy felt as empty emotionally as she was physically.
Big Mac walked into the room, quickly spotting her on the floor. “Well, there you are! Gosh, Applejack packed you away in the closet and I got busy searching for my friend who went missing. Why don’t I inflate you and get you comfortable?”
A deep seated joy welled up inside Fluttershy. Yes, yes! Use me, Mac! Finally! For some reason she didn’t care about rescue, not right now. Her marehood was already burning furiously, begging to be used. She felt so safe and at peace with Big Mac here.
He put on a pair of saddlebags, and stuffed her into the side. Fluttershy was confused and crumpled up in the bag, as Mac walked somewhere. She couldn’t tell where, but after a couple minutes had passed, Mac reached in and pulled her out.
She felt him bite onto her flank, and a warm breath of air expand inside her. Fluttershy had gone so long without feeling Mac’s touch, that she had a small orgasm rock her body. Another puff of life entered inside her, ever so slightly inflating her. The sensation was like a tiny climax each time.
Mac continued to blow air into her, restoring her shape and her feeling that everything was all right. The building pressure inside her as her owner reinflated her erased all the doubt and worry of the past few days.
After a few minutes, Fluttershy was back to her old self. She floated gently on the floor as Mac’s hoof ran along her sides, teasing her. “I sure am glad to have you back. Ever since Fluttershy went missing, I felt so horrible. At least I’ll have you forever, my perfect little doll. I love you, Fuck-me Fluttershy. You’re going to be my new favorite.”
She listened to him as he walked behind her. Mac must have had some deep feelings for Fluttershy, and she wished they’d gotten to know each other better. Yet, she had what she wanted now: she loved Mac, and he loved her, and they were about to finally fuck again.
“Wow.” Mac’s hoof slif against Fluttershy’s plastic pussy. “Still all lubed up. You sure have a nice, round ass too. I don’t remember you being this shapely. Wasn’t there a note or something that got left with you? Oh well, don’t have much time tonight.”
Fluttershy shivered as she felt Mac’s flared head push inside her marehood with a wet plop. She had been deprived of sensation for so long, and finally a thick shaft was pushing inside her. The friction was building rapidly, and as the plastic sleeve heated up, it began to shrink.
Mac felt the plastic constricting around his dick, and had to make a conscious effort not to blow his load early. The tightness seemed to grow the faster he thrust. He had never felt a sex doll like this, that seemed to respond almost like a real mare.
The burning sensation spread over Fluttershy’s rubber skin like electricity. She felt his weight on her back, as he hooves squished her front down slightly so he could fuck her while supporting his own weight. The tightness was continuing to build until the familiar sensations rocked Fluttershy’s body. All other sensation melted away as the orgasm expanded inside her, engulfing her mind.
More pressure built inside her pussy as Mac shot his load into her. She’d become so tight he could barely thrust, and Fluttershy felt each load inch inside. As she laid there and Mac emptied his balls, the plastic cooled and loosened up. Cum started to drizzle out of her pussy, which had been filled to its limit.
Mac looked at the clock on the wall. “I’ve got to wake up early tomorrow, Fluttershy, but I’ll be back tomorrow night. I promise.”
Fluttershy realized for the first time she was in a brick room, likely underground, with no windows. It seemed like a small basement, and she recalled Applejack mentioning Mac’s room in the apple cellar.
She was lifted up and carried over to a sink, and Fluttershy felt a nozzle inserted into her gaping cunt. Cold water blasted inside, washing out all the semen. A dry cloth was then run over her back as the water dripped out, and Mac stuck something fuzzy inside that tickled her and got the rest of the moisture.
He carried her on his back over to a closet in the small basement. Fluttershy finally saw that the room wasn’t empty. There was a sofa, a TV, a few posters, and three sex-dolls. The sex dolls sat next to a shelving unit in the closet. Fluttershy saw dozens of colors, and recognized all the folded up dolls on the shelves.
Oh no, he’s going to fold me up again!
Big Mac set her down on some soft carpeting and pulled the plug open on her back.
No, no please! Fluttershy whimpered. She knew now that she couldn’t turn back to normal while deflated. Her best hope had been that after being inflated for twelve hours, she could return to normal. However, if he kept deflating her, she’d never find out.
He carefully folded her up, displaying his expertise. Mac’s hooves smoothed her out into a perfect square, even on all sides, and slid her into a cubby. “Don’t worry, Fluttershy, I’ll be back tomorrow. Then, I’ll inflate you and introduce you to some of the other mares in my collection. Maybe we can cuddle overnight again. I’ll have to move a mattress down here, but I bet you enjoyed it as much as I did.”
Fluttershy listened from her dark prison, folded in on herself. She heard Mac’s hoofsteps as he walked away, and was left alone with her thoughts.
He promised we could cuddle again soon. That means I’ll have time to turn back to normal. I wonder if each time he inflates me counts? Maybe it won’t even take that long.
But what if it’s too late? What if I only had one chance after the first twelve hours? I’ve been a doll for three days now. I might never turn back. Even Twilight didn’t know it was me.
Zecora might come looking for me. She knows I took the potion, but Pinkie Promised not to tell anypony. Maybe if she realizes something is wrong? Oh, but nopony would break a Pinkie Promise.
Then again. . . the way I feel when he touches me is heavenly. Maybe, if I’m stuck like this, it’s a good thing. I’ve always been to shy to ask, and the way he tells me he loves me. . . Mac even cleaned me up and folded me neatly. Clearly he loves me now, and we never really talked as ponies.
Well, maybe this isn’t so bad and I can stay like this. If I do turn back, there’s plenty more potion. And if I don’t, well I’m just glad I’m a perfect replica. I’m sure he’ll never get rid of me.
Yeah, I’m a perfect toy now. Mac’s my owner and I love him. I want him to use me, and I can’t wait to cuddle tomorrow.
