A Normal Date in Futaquestria

It’s a new experience for you - waking up next to someone and realizing that it could be practically anybody. You don’t remember who you went to bed with last night; it could have been Vinyl, it could have been Maud or Lyra or… practically any other mare in town, really. Nearly all of them have made it clear that they’re attracted to you. Hell, it could be Princess Celestia; you’re a universally desirable sex object, you could get almost any woman in Futaquestria.

With your eyes still closed, you can’t tell much about the mare your arms are wrapped around. She’s a little wide, but that’s no problem. You run your hand over the top of her head, and find… no mane? Is there a mare in Ponyville with no mane?

She smells nice, though. It’s an exciting scent, one that awakens your sleep-dulled senses. As your eyes flutter open, you lean in to give your bedmate a good-morning kiss…

With a splut, your mare drenches your face in something warm and thick. It’s a familiar feeling, and when you lick the salty-sweet fluid from your lips, it’s clear that it’s cum that just splattered you. You open your eyes - after wiping them clean - and see something surprising.

Well… not that surprising. A cock as wide as a human body, with an oozing slit as big as your mouth, isn’t particularly out of place in Futaquestria. And the fact that you were apparently hugging this giant gray cock all night long, sleeping with the huge, soft shaft in your arms… yeah, that tracks. This is the sort of thing that happens to you lately.

You lift your head to look past the giant cock and see the actual face of the mare you’re lying next to. It’s a familiar face - although since her eyes are closed, her most recognizable feature isn’t apparent. It’s your mailmare, who was one of the few ponies you saw regularly during your months of isolation. She seemed very friendly - even more so than the average pony, which is a pretty high bar - and you feel bad for not being very sociable in those days.

But if you slept with her last night, maybe you’ve started to make it up to her. She certainly seems happy; whatever happened last night left her with a smile on her face. She’s still peacefully sleeping, and it would be a shame to wake her - so you just lie in bed beside her, embracing her giant cock and admiring her body. Her messy straw-colored mane and her twitchy gray ears are adorable, and her giant tits are… well, not adorable, but they’re pretty great. Not as outrageously sized as her cock, and not quite the biggest boobs in town, but even for Futaquestria they’re huge. Bigger than your head, with perky pink nipples you just want to wrap your fingers around.

Come to think of it, your mailmare - Derpy is what people call her, you think - didn’t have a cock this big, did she? No, you definitely would have noticed; the dick you’re hugging is flaccid, but it’s thicker than your waist and has to be at least three feet long. She definitely wasn’t dragging around a cock that size when she delivered mail to your little cottage.

Speaking of which, you’re not in your cottage; clearly, Derpy brought you back to her place. The walls are pale, and seem kind of… insubstantial? Does Derpy have a house made of clouds? Good thing you realized that before you tried to get out of bed…

Derpy’s eyes open, and her peaceful smile broadens as she gets a look at you. Her right eye drifts sideways as she reaches out a hand to stroke your cheek, but her other one stays on you. “It’s really you,” she says.

“Uh, yeah,” you say. “I don’t know if we were ever properly introduced… I mean, I saw you deliver my mail, but I never really said hello…”

“Aw, you gave me a nice enough ‘hello’ last night,” says Derpy. “I can’t believe I’m the one who got to take you home… but then, I guess I did kind of cheat… all I have to do is skip my meds and I’m the biggest cock in Ponyville…”

“Your meds?”

“Yeah!” says Derpy. “You know that thing that happened to Lyra the first time she fucked you? Where her cock and balls got really huge?” You nod. “Well, that can happen to any pony if sexual energy sort of, like… builds up. And I have this condition where it happens to me all the time.”

“Oh,” you say, recalling the day when Lyra’s cock grew to a six-foot-tall behemoth. That was a good day.

“This is where you ask if that condition is related to my eye thing,” says Derpy, with a little smirk. “And then I say, ‘what eye thing?’ and you’re like, ‘oh, never mind.’”

That gets a laugh out of you. “So you just grow and grow?” You ask. You shift your legs under the covers, and your toes brush against her nutsack. Her balls are about as big as you’d expect from the size of her cock - well over watermelon-sized.

“Well, I don’t grow forever,” says Derpy, “But I get pretty big if I skip the meds that keep me at normal size.”

“Why would you ever take your meds?” you say, running your hand over the wide flared head of her huge gray cock. “This big cock is beautiful…”

You kiss the edge of her flare, licking at the soft, musky skin and stroking her shaft with both hands. “Wow, I think I’m still coming down off that party drug, Wyld Stallyn,” you say, as you end the kiss. “I’m really into this big dick.”

“Well, it’s kind of a pain to drag around a giant cock and balls,” says Depry, a blush blossoming on her face, “But if I had you hugging my dick and giving it sweet little kisses, maybe I could live with it…”

You descend again, planting a dozen quick kisses all over the head of her dick. It’s wider than your head, so there’s plenty of ground to cover… and you’re really taking your time, giving all your love to this giant cock.

Your infatuation with Derpy's cock sparks a memory of last night at the club; you remember how beautiful all those mares looked, how tantalizing their long, hard cocks were… how good it felt to be in a room saturated with their musk and the scent of their cum. The memory turns you into a whirlwind of passion, kissing at Derpy's head and her dripping slit while she giggles and squirms under the covers… and in time, the memory overtakes the present completely, drawing you into a flashback.

Bon Bon and Lyra join you on the dance floor after Vinyl has her way with you, and you spend the length of a few songs just dancing to the pulsing beat. The sense of liberation is intoxicating; you’re the same human who had isolated himself for months, and now you're seducing dozens of big-dicked women at once with the movements of your body.

Distantly, you think about how self-conscious you would ordinarily be: you're naked, shaking a magically enlarged bubble butt - and your belly is still a little bloated with Vinyl’s load. But you know that the mares all found you irresistibly sexy - and you don't just know it, you feel it. All the lustful gazes and drooling marecocks reinforce that feeling, and you dance without a care in the world, secure in the knowledge that everything you do - every move you make - is perfect.

Over time Lyra grows bolder, and soon she’s dancing right on your ass, sliding her long, thick cock up and down between your asscheeks. It feels great - although Lyra is clearly enjoying it even more than you, judging by the hot spray of spunk that goes up your back as she climaxes.

Blowing her load on your back doesn't reduce Lyra’s enthusiasm, but it does put her in the mood for something different. As soon as the last jet of cum leaves her cock, she dances her way over to Bon Bon and points her in your direction, saying something you can't hear.

In an instant, Bon Bon is behind you, groping your big round butt and tickling your crack with the tip of her hard cock. “You’re mine, human stallion,” she says, steering you towards the bar.

“Woah,” you say, “You’re pretty pushy for a girl who’s not into guys.”

“You got a nice soft flank, just like a mare,” she says, giving your cheeks a squeeze. “And I bet it feels real good on the inside, too. What’s the matter, gorgeous? Don’t you wanna be my mare?”

“No, I definitely do,” you say. You let her bring you to the bar, and you brace yourself against it, ready for what’s coming.

“Besides,” she says, slipping her cock between your cheeks, “Lyra wants to see me fuck your ass, and I would do anything for Lyra.”

“Aw, that’s sweet,” you say. “You’re a good girlfriend, Bon Bon.”

Bon Bon claps her hand onto your ass and jams her cock balls-deep in your ass with one thrust. “I’m the best fucking girlfriend,” she growls.

Bon Bon energetically fucks you over the bar, accelerating quickly to a confident rhythm. Her tits are smushed against your upper back, and her thrusting cock is a wonderful fullness in your butt. For a lesbian, Bon Bon really knows how to fuck a dude in the ass.

“Get ‘im, baby,” moans Lyra breathlessly. “Get him, fuck him, fill him up, I love you, baby…”

“Fuck,” gasps Bon Bon, “He’s… pretty good… actually…” It’s not long before Bon Bon’s ready to blow. “Lyra,” she grunts, “I’m gonna cum… I’m about to fill your human stallion’s big round butt with a hot load of cum…”

“Yeah, fill him up,” says Lyra, “empty your nuts in his tight little butthole, baby…” She hops over and puts her free hand on your belly. “Bloat his belly with a big creamy load…”

Bon Bon hilts herself in your ass, and you cum, shooting your load against the underside of the bar. Bon Bon comes too - but since she’s a big-dicked mare, she comes ten times harder. Her cum shoots way up inside you, erupting like a geyser in your asshole. And Lyra, seeing your belly start to bulge with her girlfriend’s spunk, groans in absolute bliss and fires a long rope of thick white cum into the air.

“Fuuuck yeah,” moans Lyra, her cock firing again and again. “Fuck up his tight little asshole baby, pump him with your hot load, empty those beautiful balls into his big round butt…”

Bon Bon pulls out of you, her cock leaking as it softens, and puts a hand on Lyra’s shoulder. “I think…” she pauses, giving Lyra a moment to calm down… but her girlfriend just goes on babbling as her cock fires off spurt after spurt. “Yeah, she’s overstimulated. I need to take her home or she’ll never stop coming.”

“Aw,” you say, “It seemed like she was making pretty good progress, with the meditation and all…”

“No, she definitely is,” says Bon Bon, “But she’s wanted to see me fuck your ass for a long time. I was pretty sure this was gonna happen the first time you and I fucked.”

“Well, I’m glad she liked it,” you say. “And… you seemed to enjoy yourself well enough too.”

Bon Bon laughs. “I was pleasantly surprised,” she says. “I have a feeling Lyra’s gonna want to see that again… and I think I’m actually looking forward to it.” She puts her arm around Lyra, and the two of them leave the club, leaving behind a trail of spunk from Lyra’s endlessly spurting cock.

You find a barstool and take a seat, looking over the rows of bottles behind the bar. You are a little thirsty… maybe some mare wants to buy you a drink.

It doesn’t take long for a mare to sit down next to you. Even out of the corner of your eye, you can tell she’s a big girl; huge gray tits bounce into the periphery of your vision as she takes her seat at the barstool, and you turn your head to take in all of her.

And it’s Derpy, of course - you recognize her cutie mark, as well as the wide round ass it’s stamped onto. Not all the mares in Ponyville have a butt bigger than yours, but Derpy has you cleanly beaten in that department. And her cock is bigger than you remember; the apple-sized cockhead is poking up from between her big gray tits, drooling precum into her cleavage. She’s usually friendly, but she’s not looking in your direction now - she’s just staring straight ahead with a slightly nervous look on her face.

“Hey, Derpy!” you say, leaning towards her and raising your voice to be heard over the music. “You look really hot tonight! I kinda wanna bury my head in your tits and suck on your big fat cock.” That’s the party drug talking; thanks to the dose of Wyld Stallyn you started the night with, that dirty talk flows naturally from your mouth. Even after your “sexual awakening,” you’ve mostly been a passive party in the process of seduction… but Wyld Stallyn has made those inhibitions disappear. Now you’re talking like a native of Futaquestria, openly propositioning mares at the bar.

Derpy sits upright on her stool, and she turns to look at you. “Oh hey!” she says, giving you an anxious smile. You don’t recall ever seeing Derpy nervous before - she seemed very social when she delivered your mail. Always pleased to see you, eager to talk but not too pushy.

But that was before you’d started to embrace your status as a sexual icon. Now your confidence - and your big, soft, very fuckable ass - apparently make you a little intimidating. It’s a nice feeling; you’re chatting up a beautiful woman with a huge ass and colossal tits, and she’s the one who’s nervous. “Hey yourself!” you say. “I’d love to talk, but the music’s kinda loud… do you wanna just fuck me in the ass?” You hop down from your barstool and sidle over to hers, putting your hand on her soft gray thigh. You slide your hand inward until you reach her cock - a stiff shaft of satisfying width and pleasant warmth.

Derpy swallows a big, nervous gulp, looking at you like she can’t believe you’re real. “Y-yeah!” she says. You slide your hand up and down her cock, feeling it thicken under your fingers - which is impressive, since it looked like it was already fully hard to begin with. “Oh…” Derpy gasps, “I’m growing…”

“Yeah, grow for me!” you say. Freed of inhibitions, you can fully admit to yourself just how eager you are to see Derpy’s big fat horsecock grow larger in your hand. You pump faster, watching the flared cockhead rise, your eyes widening as her mouthwatering cock climbs higher. Her balls are swelling too, bigger than oranges and still gradually expanding. “How big are you gonna get, Derpy?”

Derpy’s blushing now, biting her lip, seemingly struggling to find the words. “Uh… maybe I should just… stick it in?”

“Sounds good to me,” you say. “That way I can feel it growing.” You put your hands on the bar and stick out your bare ass. “Get really fucking big inside me, okay?”

As Derpy gets up from her seat, she’s trembling so much that you’re half-expecting to see her fall over. Her cock is spitting precum by the quart, making puddles on the floor of the club - and, as she positions herself behind you, shooting sticky warmth onto your back and asscheeks. She grabs your wide ass, sinking her fingers into your magical bubble butt, and parts your cheeks with her cock. It’s gigantic; last time you laid eyes on it, it was maybe fourteen inches long and four inches thick… but now, as it enters you it’s got to be six inches thick. Of course, it’s easy to overestimate the size of a cock as it’s going up your ass… but you’re pretty confident in your assessment. And besides, you’re not complaining.

As usual, your ass offers no resistance as Derpy slides herself all the way inside you. With the help of Twilight’s magic, your body is a perfect sex toy for mares of all sizes, accepting and pleasuring marecocks no matter how big they grow. And you have a feeling that’s going to come in handy with Derpy, because she’s still growing inside you. She’s balls-deep, motionless, just savoring the feeling of being inside your ass… but you can feel her dick stretching you wider, pushing deeper into you all on its own.

And then she starts to pump her hips, slowly working a full foot of marecock in and out of your ass. Through the pumping bass of the club’s music, you hear the character of the crowd’s murmur start to shift in your direction; a lot of the clientele came here to see you, and since not every mare is going to get to fuck you tonight, a lot of them are having to settle for watching you get fucked.

And you’d love to give every mare a turn with your ass, if only the night would last long enough - but if you can only accommodate a few, you’re happy that Derpy made that short list. Not only is her cock still growing, almost two feet long now, her tits are so big that they rest on your back, wobbling with every thrust of her hips.

“Damn, you're big, Derpy,” you groan. “Do me a favor and keep getting bigger, okay? I want everyone in the club to watch me getting fucked by a big gray tree trunk. I wanna feel that beautiful veiny monster grow thicker and wider in my butt right up until you shoot your big hot load.”

“O-okay,” gasps Derpy. “I… I don't think I can stop myself from growing… oh wow, everyone’s watching, aren't they? I, I wasn't planning on getting this big…”

“No, bigger, bigger, fuck me like a freight train, Derpy, you big powerful hard-cocked goddess,” you babble. “Don't you want to be my biggest? Don't you wanna turn my slutty body into a big bloated cum balloon? Don’t ever stop growing, give me that big meaty battering ram deep in my asshole…”

Derpy grunts wordlessly, her cock throbbing and bucking - and still growing. You can feel every thrust filling you, stretching your torso over Derpy's horsecock as she fucks you three feet deep. It's the closest you've come to your first time with Lyra, when her cock grew into a mint green monster six feet tall and you took all of it. Derpy’s cock is a reminder that your body is a sex toy now, built first and foremost to give pleasure to mares of any size. You're buzzing with pleasure, but what you're really excited about is Derpy’s orgasm: the pounding throb of her big gray cock, and the thick warm flood of mare cum that will follow.

And then it happens. Her first gush of cum hits your belly like a wave, and you feel yourself start to bloat. Bon Bon’s cum had already given you a prominent belly, but this is on a whole different level. The first thick, hot splatter pushes you well past the point of looking nine months pregnant - and by the time her second jet is done erupting into your asshole, you're on your way to being a blob.

It’s a familiar feeling, of course - Lyra turned you into a wobbling cum-blob when you took her cock - but you'd forgotten how good it feels. Or maybe it's better this time, with a few weeks of sexual experience behind you and the party drug buzzing through your body. Becoming swollen with marecum, turning into a sloshing, wobbling water balloon, is no longer an unfamiliar prospect… it's a blissful consummation of your new purpose in life.

At some point, you cum, groaning weakly as your arousal goes through a momentary spike. But the ongoing bliss of being flooded with spunk is honestly better - it's a full-body physical joy that remains potent even when Derpy stops cumming and collapses on top of you, practically burying your sloshing body beneath her big gray boobs. Her cock spasms, spilling its last few gallons into your asshole, and as she sighs with bliss, you hear her whisper the words, “I love you…”

Back in the present, with your lips on Derpy’s cock, you pause. Now that your memory is back in order, you dimly recall shrugging off her declaration of love; the swirl of post-coital bliss and party-drug high made it seem fairly unimportant. But now - in the light of day, with your memories in order - you have a pressing question to ask.

“Hey, Derpy?”

“Yeah,”

“...How the fuck did you fly me up to a cloud house? I was a cum blob and you were dragging around a hundred-pound schlong.”

“Vinyl Scratch cast a spell to reduce your weight,” said Derpy. “She was real happy to help!”

“What about you?” You ask. “Can you fly when your cock and bells get all giant?”

“Yeah, of course,” said Derpy. “Oh, maybe you didn't know this, but pegasus wings have this sort of inherent magic that compensates for your body weight. I don't remember the details, but apparently we couldn't fly at all if they didn't. Without magic, they couldn't, like… generate enough lift.”

“Yeah, that makes sense,” you say. “I guess everything in this world makes perfect sense, if you assume that ‘magic’ is constantly smoothing over all its inconsistencies.” You pause for a moment, drumming your fingers on her ballsack. “So last night, did you tell me you loved me?”

Panic grips Derpy. Her body stiffens, and her eyes briefly align before spinning off in different directions. “Oh geez,” she says, “oh geez. I was sort of hoping you forgot?”

“I did, until just now,” you say. “Look, it’s no big deal, people say all kinds of things when they're fucking.”

“No, no, it is a big deal!” says Derpy, picking up a pillow and burying her face. “I, I saw you almost every day, and you seemed so lonely, but I smiled at you and you smiled at me and… I started to think about like… what if I could be the mare who brought you out of your shell? But you didn't need me, in the end, which is… fine, obviously, but…”

Hmm. Awkward. You did have a budding friendship with Derpy, during your months of self-imposed isolation. She brought your mail - letters from Lyra and Twilight, mostly - and she didn't try to fuck you. Sometimes you'd chat with her though your front door… and since that window only permitted you to see her face, you could pretend you were just talking to a cute horse lady and not a tremendously busty, big-cocked horse lady.

Love, though?

“I read your letters, too,” said Derpy. “I mean, I didn't open them! I would never! But Lyra showed them to me, and I saw that you were sweet, and smart, and…” she sighed. “Sometimes I imagined you wrote those letters to me…”

Okay, a picture is starting to come together. And the old you might have been a little freaked out, but your time in Equestria has softened your heart. It's pretty clear to you that Derpy’s just a shy mare, a cute dorky romantic who fell for you. You're happy to give her a chance to really get to know you… especially if it means you get to kiss her enormous cock and get your ass filled with her cum. You raise your hand in a calming gesture, ready to tell her that she doesn't need to say another word-

“And another thing,” she says, “oh, this is gonna sound weird, but… do you know what 'fan fiction' is?”

Grimly silent, you nod.

“Well, there's this thing called the PonyNet,” says Derpy, “and there's a place there where ponies, mostly mares, gather to talk about, uh… you.”

You have a lot of questions, but for the moment you just nod again.

“I mean, you're fascinating, right?” says Derpy. “The handsome, alluring, secretive stallion from another world! There’s this sort of subculture that likes talking about you, and sharing pictures of you and stories about you, and some of the stories are, you know…”

Yeah. You know.

“So I wrote a story about me and you,” says Derpy. “And people liked it! And soon I was writing more chapters, and I got really into it, and… when I actually met you, for real, without a door between us…” she sighs. “I felt like I was the girl in that story, you know? The mare who had won the human stallion’s heart.

“Sorry if it's weird,” she says. “I know those stories aren't real, I know we're not… together. But I'd love… I'd like to keep fucking you, if that's okay.”

“Absolutely,” you say. “You gave me an unforgettable pounding last night, with that big thick cock of yours. I'm not going to let a little awkwardness come between me and another round with that thing.”

Derpy squeals happily, her legs kicking under the sheets. Her cock spurts a couple gushes of pre, which splashes on the cloudy walls and drips down to the floor.

“So,” you say, “what kind of stories do you like to write? About me?”

Derpy’s glee turns to a burning blush, and even her good eye is looking away from you. “Uhh… well, different stuff…” she mumbles.

“You're into different stuff?” you gasp, with mock alarm. “You pervert!” You grab a pillow and use it to smack one of her tits. “Look, I get it. Maybe some of them are embarrassing, but I want to know what turns you on. I want to know what makes your cock grow. I want to know what you're thinking about when your dick shoots a big, hot, creamy load.”

Steel Grey took one last look at herself in the bathroom mirror, smoothing out her blouse and tugging at the hem of her skirt. There was no hope of getting the skirt to hang cleanly around her thighs, of course; her persistently stiff cock made certain of that.

She'd have preferred to at least begin the interview with a soft cock, just for the sake of professionalism. But her mind was focused on the man she was about to interview, and thinking about him kept her shaft perpetually rigid and spurting.

Speaking of which, there was one last thing to take care of. Steel pulled the condom off of her cock and tied off the end, testing its weight in her hands. She'd spurted a good couple gallons of pre while she'd been in the waiting room, and the condom could take a lot more than that… but it'd be safer to switch it out for a new one before she met her interviewee. She had a feeling she'd be pumping out a lot of spunk once she was in the same room as him, and she didn't want to risk bursting her rubber.

And since this was the fanciest bathroom Steel Grey had ever been in, it was no surprise that it was well-stocked with courtesy condoms. She took one from the basket, tore open the wrapper, and rolled it over the head of her cock…

And she froze, mouth gaping in horror as she realized that her cock was just a bit longer and thicker than it was a moment ago. No! Today, of all days, had she forgotten to take her meds?

Flip, flip, flip…

“Wha- why are you skipping ahead?” asks Derpy. “It's not boring, is it?”

“No, sorry,” you say. “I just want to see the part that I'm in…”

“To what do you credit your, uh… ahh…” Steel shuddered in her seat, and her cock shot another splatter of cum into the sagging condom. She could feel herself growing each time her cock pumped out more spunk; a little longer, a little thicker. Each jump in size was barely perceptible, but they were quickly adding up; she was easily eighteen inches now, the shaft thicker than her ankle. Her nutsack was dangling off the chair, hanging almost to the floor - and the condom she wore had already drooped to the floor, gallons and gallons gently sloshing in the bloated reservoir.

The human watched her dispassionately from across his desk. “Do you need some help with that?” he asked. His eyes were powerfully focused, just like they’d been since Steel Grey entered his office - and feeling those focused eyes on her cock made Steel feel like she was about to shoot again.

“N-no,” said Steel. “I’m sorry, sir. I was just about to ask-”

“You were about to ask, to what do I credit my success?” said the human, rising from his tall, black office chair. “But I think there’s a different question you want to ask me. Or… a more specific one. You want to ask me if my success is due to… the way I make people feel.”

The human turned away, facing the tall, wide window that made up the back wall of his office. Steel Grey audibly gulped; this was the first time she’d seen the human’s ass in person. In motion. Through his tight, dark slacks, she watched his perfect ass wobbling as he moved - and her cock surged again, growing a full two inches and shooting a heavy gout of spunk into her condom.

“But before I answer that question,” said the human, turning to face Steel Grey once more, “I’d like to know what you think. You took this assignment, after all; you must have an opinion about me. How do I make you feel?”

He approached her chair, and she sat there - frozen - struggling to meet his penetrating gaze. “Or maybe I should ask a different question,” he said - and then he reached down with one hand, running his fingers over Steel Grey’s shaft from base to tip. “How do you want me to make you feel?”

Steel Grey’s cock bucked. All in an instant, it grew fatter and longer - and it pumped out a gallon of pre from the tip. Then another, and another, and -

The condom burst, spilling its contents over the office’s soft carpet, sending a spreading pool of creamy white over the floor. “Ahh, I’m so sorry!” squealed Steel Grey, her cock still spurting. “Let me - let me get that…”

“No, it’s fine,” said the human, cracking the first hint of a smile that Steel had seen on his face. “I think I have my answer.”

You close the book, and the crystal embedded in its spine visibly “powers down.” You make a note to familiarize yourself with the technology of this world; there’s clearly a lot you don’t know about. Twilight Sparkle, after seeing your discomfort with the magic ring, supplied you almost exclusively with nonmagical items during your months of solitude - and that was a kind gesture, but it left you poorly informed about the way this world works. It seems like magic is discreetly integrated into all kinds of things in Futaquestria: people, books… maybe even the bed the two of you are lying in.

“So that’s what you like, huh?” you say, giving Derpy’s nuts an affectionate pat. Her cock, which started out soft this morning, grew stiff while you were reading her work - and now it’s pointing straight up, precum drooling down its length like wax from a candle. “You want me to be an icy billionaire to tease and dominate you?”

Like her counterpart in the story, Derpy begins shooting pre even harder. Her cock was already drooling, but now it’s a fountain, nearly staining the cloudy ceiling of her bedroom with each spurt. A thick glob lands on your chest, and you scoop it up and lick it off your hand.

“Well-” says Derpy, “I mean… that was just my most popular story, so, so, I don’t know if it’s my number one fantasy…”

“Well, that won’t do,” you intone coldly, grabbing a handful of skin from her big gray nutsack. “I need you to be honest with me, Miss Derpy. When I ask you a question, you will answer me truthfully, and you will call me sir.”

“Y-yes… sir,” Derpy gulps.

“That’s better,” you say. You shift your body onto hers, sitting your huge ass on her watermelon-sized nuts. “What I require is a mare whose cock will grow as large as I want… and who can shoot nice, big loads of thick, creamy cum for me.” You wiggle your butt, working her shaft into your asscrack. “Enough to fill me up… Enough to coat me in jizz… enough for me to swim in, if that’s what I want. And if you’re going to be that mare, I need to know what makes you very... very horny.”

“Okay… sir…” gasps Derpy. You can feel her cock bucking, and precum is pouring down her cock, dripping onto your back. “I’ll be big for you, sir… I’ll cum big loads for you…”

“I know you will, Miss Derpy,” you say, grinding your ass against her shaft. “I can tell you’re dedicated. Now show me, Miss Derpy. Grow larger for me. Grow thicker and longer, and don’t stop until I’m ready for you to cum-”

Derpy grunts, and her cock shudders between your asscheeks. “Ah- I’m coming-” she gasps, clutching her shaft to hold it steady.

You whip your head around, and look up just in time to see the first gush erupt from her cock - now about four feet long - and splatter on the cloudy ceiling. “Aw, come on!” you say, breaking character. “You couldn’t hold on until you actually stuck it in me?”

Derpy stutters out an apology, but you’re already springing into action. You really want to get that cock in your ass, and you hate to see so much cum go to waste, and… fuck, you’re a real slut now, aren’t you? You leap off the bed, landing on the soft, cloudy floor - which thankfully supports your weight - and press your palms against the wall. “Come on, Derpy,” you say, shaking your ass in her direction. “Get off your ass and fuck me before your nuts are drained!”

Derpy groans, struggling to move her immense cock and balls off the bed. Dragging sheets behind her, she hits the floor - and her cock slams against the floor, sending a ripple through the cloudy material. A streak of cum slaps onto your back, and you thrust your ass in her direction, trying to motivate her. She lumbers closer, shoving her spurting cock ahead of her, until the flared head is shooting her load right onto your asscrack.

You figure that’s as far as she’s going to get; if she can barely move with a cock that size, she’s not going to be able to fuck you with it. But it’s propped up well enough that you can back into it - and your butt, magically enhanced to be perfectly fuckable, takes readily to the task of swallowing up Derpy’s cock. Your cheeks part, and your asshole widens, easily accepting the twelve-inch girth of her cockhead.

And as soon as she’s inside you, her cum has nowhere to go but into your belly. You groan with satisfaction as you feel your stomach start to bloat; this feeling of being filled, of gradually softening into a bloated blob of thick, sloshing mare cum - it’s intensely stimulating, while also marvelously relaxing. Before your stomach weighs you down too much, you back yourself further onto Derpy’s cock, getting a couple feet of throbbing mare-meat inside you. By that point, there’s enough cum inside you that your legs barely reach the floor - and the pumping shaft inside you is driving you to the edge. You cum, shooting your load onto the underside of your swollen gut, and then relax as Derpy’s climax peters out.

Once she’s completely unloaded inside you, Derpy falls forward, collapsing on top of you with her cock still halfway in your ass. Her tits on your back are wonderfully soft - but you are much softer. Your body supports her like a waterbed, flattening slightly under her weight, as she makes herself comfortable on top of you.

“I love you…” she sighs - then catches herself. “Sorry…”

“No, don’t worry about it,” you say. “I’m pretty lovable.”
