Pinkie Pie Impregnates Ponyville or "Satyriasis"

For the first time in her life, Twilight fell backwards on her bed with another pony hovering over her, grinding their body against hers and breathing wet, heavy groans onto her face.

“Pinkie,” she said from underneath her friend, trying to restrain the assault. “You have to calm down.”

Pinkie continued giggling, and Twilight wondered if she had even heard her plea. Pinkie kept pushing down on her, pushing her into the mattress as she climbed on top of her, straddling her friend and pushing all the air out of her lungs. Pinkie was a bit heavier than she looked, and she was pudgy to begin with.

“Pinkie, please,” Twilight said, gasping. She wasn’t sure she was louder than the laughter. “Pinkie.” She looked up into her friends face but only saw a laughing mouth filled with teeth and cavities. Twilight could almost feel the sticky-sweetness of her breath hitting her face in palpable waves.

The mouth shut, and Pinkie’s enunciations became a trail of mumbles. Twilight opened her mouth again to beg the pony riding her to just calm down maybe a little bit and let her catch her breath, but before she could get more than a syllable out Pinkie dove down and smothered Twilight’s mouth with her own, pushing her tongue into her friends mouth.

Now, Twilight could taste the sugar. Her first kiss, she blankly considered, as her friends tongue invaded her and pushed its way into every crevice of her mouth. Twilight gave up on her mouth contributing anything to this interaction and started breathing through her nose. Giggles that weren’t hers began to fill her throat. Pinkie’s grinding kept getting hard, and Twilight could feel it – resting, hard and fleshy, on her heaving stomach, rubbing against her coat. She tried, as she stared into Pinkie’s closed eyes, to make some assessment of its length or girth – purely from a detached perspective, of course.

Pinkie was grinding so hard so hard into Twilight that she might as well have been humping her. Twilight had to call her back to her sense before it got too out of hand – nothing about this was ideal, but she wasn’t going to let Pinkie Pie decide everything about her first time.

Wrestling against Pinkie’s body, she managed, after the wet make-out with her friend had ended and Pinkie began kissing her face and nipping at her neck, to pull her forelimbs out from under the gyrating pink body collapsed on top of her. She grabbed Pinkie’s head on both sides and – by Celestia, Pinkie’s a lot stronger than she thought – tried to pull Pinkie’s head away from her, succeeding only after a minute and only because, it felt, Pinkie let her.

Pinkie still struggled against her grip, making it clear how much she wanted to get back to the action. She lifted herself up off of Twilight and finally let her gasp in some air. Her butt was in the air and shaking, making her frizzled tail wag back and forth. Pinkie’s tongue hung out of her mouth as she desperately tried to take in breath – apparently in her excitement the pony had forgotten to breathe.

Twilight tentatively let go of Pinkie’s head, flinching as she expected the pony to leap right back to it. When she didn’t, Twilight slid back on her bed a bit, up to her pillows. Pinkie Pie followed her, scrambling up after her.

Even though Pinkie was hovering above Twilight now instead of clumsily thrusting against her stomach, Twilight could still feel...it. Just the tip now, just resting towards the bottom of her stomach where her coat was thinner – she felt the vaguely slimy moisture that coated the end, leaking out. It was pulsing and twitching like a heartbeat. Twilight shivered. Pinkie’s eyes were shimmering as she stared down at her friend.

“Pinkie,” Twilight began after her breathing finally began to settle. “I know you’re excited. I am, too. But you have to be careful, okay? You’ve never done this before and neither have I. You’re lucky I’m letting you do this, so calm down a bit and take it slow.”

Pinkie nodded furiously and started to dive for Twilight’s face again. A pair of forehooves halted her.

“I’m serious, Pinkie. I’m in control here. J-just take it slow, please? For me.”

Pinkie Pie’s smile fell from a full grin to just the corners of her mouth twitched upwards. She raised one eyebrow and looked down at Twilight. Twilight wasn't sure whether anything she said was genuine or just her idea of a flippant joke. “Oh, Twily. You know I’d never do anything to hurt you. You’re, like, one of my best friends! I’m excited because I know we’re going to have lots of fun together now and you’ve given me this now and now I can see just what a little cutie-pie you are. I know what I’m doing, and I pinkie promise I’ll be super duper careful and not do a thing to hurt you okay? Okay okay?”

Twilight stared back at her friend. “Don’t ever call me Twily again.”

Pinkie Pie giggled and leaned back down towards her. Twilight raised up, slightly, to meet her this time. The kiss they shared was lighter and calmer than before. Kind of like the salvaged remains of the first kiss Twilight had imagined with some demure stallion years ago – a dream Pinkie subverted and supplanted a few seconds after Twilight made an hesitant suggestion that they make use of the tool Twilight’s errant transmogrification spell had left on Pinkie’s body. She didn’t know if she should regret it, too hard to tell, too hard to think. She’d been thinking about stallions a lot lately and how busy she was and how unlikely it was she was ever going to find someone who cared about her to do this with her but now Pinkie was on top of her rubbing against her did anyone ever tell her her hair smells like bubblegum is it too late to tell her to stop I’m not -

“Can I put it in?” Pinkie said, breaking off the kiss and leaning back.

Twilight took in a deep breath, and told herself it would be okay. “Remember. Go slow.”

Pinkie nodded and looked down between both sets of her legs. She stuck her tongue out as she tried to get some visual guidance for ‘putting it in’. Twilight couldn’t stand seeing her friend be so inconscient about this, this huge act for her, this huge step in her life. She shut her eyes.

“I swear, Pinkie. If you hurt me I’m going to take back that thing, and I’m not going to use magic this time.”

The tip brushed up against her. She could feel it and heard Pinkie’s tiny gasp when she had found what she was looking for. It pushed up against her, lightly, testing. It was slippery now, and hot, so much hotter than the rest of Pinkie, as hot as the inside of her mouth, burning. Every muscle of Twilight’s body tensed up and she rested her forelimbs against Pinkie’s, pushing onto her friend from support. She felt Pinkie rocking back and forth, rubbing it up and down onto her touching her in places she’d only ever touched to herself in the dark. Celestia, she was big – bigger than Twilight could have thought or dreamed so much bigger than the toy tucked under her bed and now this thing this huge thing was going to be inside of her and Twilight felt Pinkie tense up and plant her hindlegs solidly outside of Twilight’s own and line up and Pinkie was snorting all the breath going through her nose and she leaned back just one heavy thrust is all it’d take Twilight grit her teeth and prepared to suppress a scream that was going to be forced out of her any second counting down internally in her head Pinkie took in a big breath of air and

“Wait!” Twilight shouted, opening and her eyes and let a tear roll from them.

Pinkie let out an exaggerated groan, “What now, Twilight?”

“I...shouldn’t you wear protection? I read somewhere that stallions have to-” Twilight could still feel it on her, down there, throbbing at the same interval that Pinkie’s chest rose and fell as she stared at Twilight, apparently unable to decide on a expression between amusement and frustration.

“Twilight, I’ve been filled with lots and lots of these things before and I’ve never been protected. Trust me, it’ll be okay!”

Pinkie sat down. It was still hard, still pulsing just resting on there. How could Pinkie just let it sit there like that so close just laying there? Twilight stared down at it. Just inches away, a single thrust from tearing a part of her identity away for ever and replacing, a second from changing and if Pinkie wanted she could hold me down and I couldn’t do anything about it Celestia that’s so

“You do trust me, right, Twilight? That’s why we’re doing this.” Pinkie said. To Twilight, it sounded sincere – though, with Pinkie, it’s impossible to know.

Twilight somehow tore her eyes from what she was staring at and met her friend’s gaze. Before she could answer, though, Pinkie looked up at the ceiling and brought one of her forehooves under her chin.

“Can I even knock you up? I wonder what would happen I mean that’s why I make all the stallions pull out of course. You attached this big thing to me but I’m still a mare, right? I don’t think it works like that. You’re the smart one, Twilight, is that how it works?”

How could Twilight answer something like that? She didn’t want to even if she could. Even now she could feel regret seeping in. She had to get this over with or she’d end up hating herself before it even started.

“Pinkie, it’s okay. Just, do what you make the stallions do, okay? Pull out before you finish.” Twilight answered, moving her hips slightly; weight and heat of the thing resting on the bottom of her stomach was beginning to become uncomfortable.

Pinkie grinned and stood back up, nodding. “Roger-doger, Twi-pie!” She lined herself up properly again, and readied herself. Twilight held onto her friend for support, again.

“You better pull out. I’m warning you, Pinkie. You’d better.” Twilight said.

“Don’t worry, Twilight.” Pinkie said. She wasn’t even looking at Twilight and gave the reply absentmindedly through clenched teeth as she stared downwards.

“I’m serious, Pinkie! I can’t g-”

“Shhhh...” Pinkie said, and Twilight did. “It’s going to be okay, Twilight.” Pinkie looked up and into Twilight’s eyes. “Do you wanna watch it go in?”

A little tremor shuddered through Twilight’s entire body at that question, and she swallowed back a moan. She’d never felt anything like that. She had no idea what any of it meant, but it felt so good. It provided her response for her.

“Yes,” she told Pinkie, sighing as she said it.

Pinkie leaned in and gave Twilight a quick kiss on the cheek, then lifted her own body up. The both of the stared down, across their stomachs.

Twilight resisted her urge to scramble away as she saw for the first time in stark detail just what was going to happen. How did she manage to make Pinkie so big? It was mottled, just like a proper stallion was supposed to be. Pink near the base, where a set of balls swung, and evening out to a fleshy tone as it got closer to the tip, where, as Twilight could now see glimmering in the faintness of the setting sun, a clear bead of liquid had drooled out and run down part of her length.

Twilight held on to Pinkie hard as her friend made diminutive movements forward, until, gently, it parted her lips and Twilight suddenly had a hard time breathing. She couldn’t be that wet already, right? Sure, she was excited about this, but she wasn’t that-

Pinkie pushed forward another bit and part of her finally entered Twilight. She saw it go in, saw it disappear inside of her, somehow feeling even bigger than it seemed if that was even possible. Pinkie let out a tiny grunt and continued pushing, tiny tiny pushed, inch by inch getting deeper.

“Fuucckkk...” Twilight said, unable to blink as she stared at her own body taking this massive thing inside of it.

Pinkie gasped loudly and stopped her movement, looking up at Twilight.

“Twilight!” she shouted.

“What?” Twilight shouted back, mind racing with a million things that could have gone wrong.

“Oh my gosh. You said a bad word!” Pinkie’s jaw hung open.

Twilight blinked at her.

“What would your parents think?” Pinkie said.

“Please don’t bring up my parents right now, Pinkie.”

What did Pinkie expect, that Twilight would just remain quiet while she shoved that thing inside of her as far as it could go? What would her parents say if they found out she was using her magic to give her friends dicks and getting fucked by them? What would Dad say if I brought Pinkie home and told them that I-

“Can I keep going, Twily?”

Why are you asking me that. Why do you keep asking for my permission. “Yes, Pinkie.” Twilight said. Just do it just do it just fucking do it already stop making me say it over and over.

“Oh, Celestia…” Twilight said. She closed her eyes again. Pinkie began pushing. Little tiny thrusts, just as she promised. Nice and slow. And still, each one made Twilight’s body tingle. Is this was sex smells like? It was so strange to smell another pony’s sweat and breath as she felt like this, so bizarre to feel this good without her own magic causing it.

“Man, Twi, you sure are wet down there. You’re making a mess all over your bed.”

Shut up, Pinkie. Shut up. “Mmmmnnnn…”

“You said this is your first time, right? I’m going inside you so easily. How’re you feeling, Twily?”

Pinkie was so big that it felt like she was beginning to break. How did mares stand this? It was going to drive her crazy, this feeling. How could pain and pleasure be demarcated anymore? She hurt and her body was already aching, Pinkie was easily twice the size of any of her toys. But she didn’t say stop. She couldn’t.

“Twilight, I’m all the way in.”

Twilight leaned up and opened her eyes, blinking to clear away the tears. What? Already? Pinkie was right, though, Twilight could feel the heavy balls resting against her body. Pinkie was fully hilted inside her friend. What there something more, though? Some spell had to give Pinkie something more, something longer, thicker, warmer. Something that would make any mare lose her mind the way Twilight was losing hers.

“Pink-”

“I’m going to start railing you, okay? Is that okay, you horny little mare?”

Yes. Oh Celestia, yes. “Go sl-”

But Pinkie was already gone, back in her own little world of being a stallion. How did she adapt to this so easily while Twilight was left barely able to speak? She started calmly, pulling out only a little bit before grunting a little and pushing back in. Each time Pinkie pushed back into her, Twilight heard a barely audible slap of Pinkie’s body hitting her soaked rump.

Twilight couldn’t describe it, how she was feeling. She felt so absolutely full and just wanted more. She leaned up and gave Pinkie a quick kiss and a nuzzle on the cheek as if she was rewarding her and coaxing her onwards. Twilight already felt satisfied, whole, in ways that never happened when she touched herself even if she brought herself to orgasm a dozen times in a day in a desperate search for the completion that she was feeling now. It never felt like this. This is was how pleasure was supposed to feel, with a grunting pony towering over you for you to kiss and touch and writhe with.

Pinkie was beginning to pick up the pace. Twilight’s own body was out of her control at this point and she had let go of her grip on her friend, so when Pinkie pushed into her harder, her body shoved upwards, crumpling the neat covers under her and pushing her pillow against the wooden headboard. Twilight tried to slide back down to make things easier for Pinkie but her friend was too eager, too frantic, breathing heavy, a small moan with each thrust, mouth open wide, entire body rocking into each thrust and Twilight couldn’t sit still. Twilight was pushed until her body was practically leaning up against the headboard. That was a stable enough surface that Pinkie’s increasing speed was easier to manage, even though it made the entire bed shake and creak each time Pinkie slammed against her.

Pinkie repositioned her hooves to make the movements easier, inching her hindhooves closer to Twilight and resting her forehooves on top of the headboard, above Twilight. Pinkie was completely towering over her now, overpowering her, consuming her. How could it feel this good. Twilight knew then that this couldn’t be the last time this happened, she wouldn’t let it. She saw Pinkie’s chest heaving, her fur soaked in sweat. Twilight leaned forward and kissed it, licked it. Pinkie was stunning in ways Twilight had never realized until now.

“Twily…” she thought she heard Pinkie say above her. Twilight didn’t respond because if she opened her mouth she’d be screaming and wasn’t sure if she could stop.

“This feels sooooo good,” Pinkie said, struggling with the sentence through groans and panting.

Twilight kept kissing Pinkie, sometimes able to reach her neck when Pinkie leaned to shove her cock back inside her. She reached up and wrapped her hooves around Pinkie’s torso, and Pinkie leaned down to accommodate. This was perfect, rubbing her whole body against Pinkie’s, so close to her, able to feel her sweat, smell her. Twilight’s whole body shivered and gyrated when Pinkie fucked her. All these sensations all at once, too tactile. Pinkie’s thrusts were short, eager, and rough. Animalistic pleasure. Rutting. It felt too good.

“Stallions are always tryin…” Pinkie said, not at her, above her. Did Twilight miss some of her friend’s babbling? It didn’t matter, it didn’t matter, as long as she kept moving, kept feeling so perfect, it didn’t matter. “...cause it feels sooooo good. You’re such a good fuck, Twilight.”

She was a good friend, yesterday and now she was a good fuck. Twilight couldn’t complain about the change. She tried to open her mouth, the sentence she was going to say already turning to a mush of curses and proclamations of Pinkie’s perfection even as they formed inside her head, but that wasn’t what left her mouth – the first syllable became a long, loud moan. Twilight tried to silence it, somehow but she couldn’t and another started as soon as she caught her breath.

Pinkie leaned down down, using Twilight’s grip to reposition her partner, then collapsed on her. Twilight was still moaning. Pinkie couldn’t remain standing and it didn’t matter, only one part of her body mattered now. She nuzzled against Twilight face and Twilight bent over and opened her mouth against Pinkie’s, kissing her hard and hungrily. The moaning became muffled and she caught Pinkie’s grunts inside of them.

“Fuck,” Twilight said, her voice throaty and wet.

Wet bodies slapping against each other rhythmically, their hearts beating like a chorus to their vocals. Twilight was crying. She felt a build up, something deep in her, and she came, screaming that fact into Pinkie’s ear as she squirted all over her friend’s cock. Pinkie’s rhythm didn’t change by a single beat.

There was a sound downstairs, outside maybe. Twilight opened her eyes and tried to blink away the blurriness. Pinkie continued above her, powerful and oblivious. Spike was at Rarity’s right? She locked the door. If Spike walked in and saw her like this would Pinkie even stop fucking her? Would she make her?

“Pinkie…” she said.

“Twily...you’re really hot.” Even after all that had happened, those words gave Twilight an unfamiliar, unsettling feeling deep in her chest. She wanted to cum again. Twilight wanted to let Pinkie fuck her for the next few hours, but Spike…Pinkie had to be close.

“Twilight, I’m…” Pinkie said, and Twilight saw that her eyes were wet with tears and passion too. She didn’t slow down.

“Pinkie, p-pull out,” Twilight said as evenly as she could through her ragged breath and sex drenched conscious.

“Oh gosh,” Pinkie said, not slowing down, “Twilight you’re so hot.”

“Pinkie, y-you should...oh fuck, you should pull out now…” Twilight said, trying to keep her eyes open, trying not to get lost and lose her mind in the rhythm of Pinkie rutting her, trying not to have her sentence devolve into ‘I’m cumming!’ again…

“I’ll get you off with my hooves now, please...pull out,” Twilight said.

And suddenly - and it felt sudden, as if it happened in a non-moment and there was nothing Twilight could do and no possible way she could react - Pinkie’s thrust faltered to a stop and her the grunting moans she’d be echoing into Twilight’s ears for the past few minutes became girlish whimpers.

Slowly, as if her body didn’t want to believe it, Twilight became aware of a white hot sensation filling her, separate and yet somehow complementing the feeling of Pinkie’s cock still buried deep inside of her. Pinkie wasn’t moving anymore save for her face which was twitching and her chest which was still heaving on top of Twilight's.

“Pinkie,” Twilight said, blinking away tears. “You promised you’d pull out. You promised.”

Pinkie opened her eyes, and turned to stare at Twilight. She still had a dull, dumb smile on her face but that quickly faded when she saw Twilight’s expression. She grunted as if discomforted, and languidly rose to her hooves, slowly picking her shaking body from Twilight’s as a cold sensation ran through Twilight, either from fear or the sudden absence of flesh rubbing against hers.

Pinkie slowly backed up from her friend. Her cock slid out Twilight and Twilight could feel every inch of it, every throbbing, warm, perfect inch of it, sliding out of her slowly with a disgusting squelch. She could feel a warm fluid dripping down her. She stared at her own body, then back to Pinkie.

“There, I pulled out,” Pinkie said, managing a sheepish grin at Twilight.

“You Pinkie-promised you were going to pull out,” Twilight said. She felt like she should be doing something. Rushing for the shower. Cleaning herself completely. Looking up a spell or something to fix this problem.

“You promised.”

All she could do was stare down her own heaving chest, acutely aware of the way she was still twitching, still coming down from the high of pleasure. All she could was stare at Pinkie’s cum-covered cock, still dangling, half-hard and pulsing, between her hind legs. She blinked. Her mind felt like it had come loose.

“Whoops,” Pinkie said.
