"Oh my gosh!" says Pinkie Pie, her eyes gleaming. "Look at that big bouncy cummy tummy!"

You chuckle. You feel a little exposed, but Pinkie's admiration is so genuine - almost innocent - that it puts a smile on your face. You look ridiculous, really - your body is still a living cum-balloon, bloated into enormousness by Lyra's oversized orgasm - but the mares of Ponyville seem to find you as sexy as always. You suppose that makes sense - subjecting yourself to this level of cumflation signals a high degree of sexual availability. A stallion wouldn't normally get this big unless he let himself get fucked by dickmare after dickmare, so your body, at the moment, is an implicit invitation for more horny mares to pump you even bigger with their cum.

And while you're beginning to come around to the advantages of living in a world of big-dicked mares, you're not quite ready to be a public cum-dump. So you're grateful that Twilight levitated you off Lyra's cock and teleported you into her library. You've been lying there, face up, while Twilight rests her body against your sloshing gut. She told you that you'd be back to normal size by tomorrow morning, and she's been keeping you company by reading to you.

And then Pinkie Pie showed up. Pinkie wasn't exactly a gossip - not in a malicious way, certainly - but if something happened in Ponyville, it rarely took her long to learn about it. Doubly so, if it was something that she might consider cause for celebration.

"Ooh, he's like a bounce house!" she says, sinking her hands into your swollen belly. Pinkie's pretty bouncy herself; she's shaking with excitement as she gropes you, and her chubby body jiggles from top to bottom. Pinkie's body may be big, but she's no exception to the everyone-is-beautiful rule of Futaquestria; her flab is perfectly proportioned, surrounding her frame with a pillowy pink cushion of soft flesh. Her tits are some of the biggest in Ponyville, sitting atop her belly and bouncing with every movement. Her cock doesn't compare to Twilight's, but on a normal-sized pony, it's uncommonly big and thick - and it's well on its way to being fully hard.

"Can I bounce on you?" she asks, fixing you with a gleeful look that's hard to say no to.

"Uh... Twilight?" you say. "Can she bounce on me?" Pinkie's a big girl, and you wouldn't want her jumping on you under normal circumstances - but if your body can absorb a tidal wave of marecum, it's clearly a lot more durable than normal. You're still wearing Twilight's ring, which is supposed to make you more resistant to harm in addition to its primary effect of making your ass huge.

"Sure," says Twilight. She sounds quietly amused by Pinkie's goofy request, and she lifts herself away from your body. "I've been using him as a pillow for a while, so it's only fair that you take a turn."

Pinkie squeals with excitement and leaps into the air above you. You cringe as her big, wide body hits your belly - but it doesn't hurt at all. Just as she no doubt expected, she sinks into your bloated gut and bounces in the air.

"Whee!" she cries, bouncing over and over. Her childlike delight is strange to see in a fully-grown woman, pony or no - especially since she's got a long, fat cock that's flicking thick splatters of precum onto your skin with every bounce. "Twilight, you've gotta get in on this!"

"That might be a bit much, Pinkie," says Twilight. She's right - Twilight has the body of a princess, which means an eight-foot frame with big, hefty bits. Pinkie keeps bouncing solo, and after having her fun, she lands on the ground and bounds over to your face.
"Are you going to be like this for long?" she asks. "My sister's coming into town and she would love this!"

Twilight laughs. "Are you sure she'd like it? She doesn't seem like the bounce house type."

"Well, she'd love to watch me having fun on his big cummy tummy..."

"I suppose," says Twilight. "But he's going to be back to normal by morning."

"Aww," whines Pinkie. She slaps your belly jovially, setting it to jiggling. "We'll just have to fill you back up tomorrow!"

You laugh nervously. "I don't know if I'll be ready for this quite so soon after the first time," you say.

"Well, just let me know when you are ready," says Pinkie. "Your sexual awakening deserves a party! All the horniest mares in ponyville, coming out to fuck you in both holes, pumping you bigger and bigger with cum until your ballooning body busts down the walls!"

"Sounds like you've put some thought into it," you say.

"Oh, I definitely have," says Pinkie, no longer sounding innocent. The head of her cock presses into the soft flesh of your belly, drooling warm precum down your cumflated curves. Just as you begin to worry that she's going to rut you here and now, she giggles merrily and bounds out the door.

Your eyes flutter open, and you attempt to stretch your arms - only to find yourself constricted by something warm and tight wrapped around your torso. It takes you a moment to realize that you were sleeping in the purple embrace of Twilight Sparkle; the giantess' arms lock you in place firmly. Last night, Twilight fell asleep while using your cum-swollen belly as a pillow, and at some point, as your body shrunk back to normal, she must have rolled over and put her arms over you.

The two of you are laying on your sides, spooning despite your disparate sizes, and you're nearly face-to-face with the head of Twilight's massive morning wood. It drips and spurts precum onto the thick rug that covers the library floor; fortunately, spells that clean up spilled cum are widely known in Futaquestria, and -by necessity - no one's better at them than Twilight.

"Mmm..." she mumbles, "thirsty again already?" Sounds like she's dreaming. "Can't let my little human go thirsty..." Dreaming about you. "Here you go... drink all you want... it's all for you..." Her dick pulses with arousal, and her big, gentle arms pull you tighter. She leans her head down to yours and draws a long, lusty breath, letting the scent of your body fuel her climax. "Get your lips around it... she says, "I want you to get every drop..."

You consider her offer. But in the real world, outside of her dream, your head is nowhere near the tip of her cock, and she's holding you too tight for you to wriggle free. You eye her cockhead, watching it twitch and spit faster and faster. Before yesterday, you wouldn't have found it so enticing. But now, the smell of her musk and her precum is making your cock hard, and you can't help but imagine yourself putting your lips around her slit and letting her fill you with a thick load of her cum. You'd seen what Twilight's loads were like; she wouldn't bloat you the way Lyra had, but you'd be walking around with an obvious cum-belly. And the thought is... pleasant. The warmth and fullness that comes with being swollen with marecum is actually a wonderful feeling.

When Twilight's orgasm hits, it shoots from her tip onto the bookshelves that surround you. Her cum is incredibly thick and potent; as her cock splatters the shelves, her ejaculate drips down the wall in slow motion, almost forming more of a pile than a puddle. You flex the muscles of your backside, wondering what it would be like to have that cum blasting into your ass; as you do so, you realize that you're still wearing Twilight's ring, and your ass is enormous. It's the big, bouncy, fuckable butt that every dickmare dreams about.

Twilight's orgasm lasts for close to a minute - being a princess means being big in every way, and her climax is no exception. She paints the bookshelves with her load, coating hundreds of books with her cum. You'd be concerned, but you know the shelves are enchanted against staining. Her orgasm is audible, each load of cum accompanied by a wet splut as it escapes her shaft.

Her arms relax as her orgasm fades, and you squeeze yourself out. You expect her to wake up, but her placid expression and soft breaths are undisturbed as you extract yourself from her embrace. Once free, you stand and locate your clothes, sitting on a low bookshelf where Twilight left them for you. You lift your pants and mentally compare them to the width of your expanded ass - there's no way these are fitting now. You put your fingers on the magic ring and prepare to slip it off, but...

A fluttering thrill rises in your chest as you consider going out with the ring still on. You wouldn't have to be naked - at Twilight's request, the black briefs that Rarity made for you are made of a fabric that can stretch to astonishing lengths. You could pull those tight little undies over your big bouncy ass, head out into Ponyville, and watch the dickmares go nuts over you. Before, the gazes of the town's mares had made you feel exposed and helpless, but now the thought of driving them wild with your body feels... powerful.

You pull on the undies, slip your shirt over your head, and tuck your folded-up pants under your arm. The library has an enchantment that muffles all sound other than speech, so it's easy to sneak out quietly. You hesitate at the front door, running a hand over the exaggerated curve of your bubble butt. You're not sure it's a good idea to go outside like this. But as long as you're going to be the center of attention anyway... why not be as sexy as possible?

You push open the castle's front entrance and step out onto into the Ponyville morning. Heads are already turning, which would be the case anytime someone was entering or exiting the castle. But because it's you coming through those doors, stares linger, and marecocks grow. And your giant, perfectly fuckable ass makes those stares last even longer. Two completely entranced mares, with their eyes glued to your bountiful backside, smack into each other as their paths collide.

Already, this feels good to you. You still feel exposed and vulnerable, but in a nice way. Like undressing in front of a beautiful woman. Except it's a whole town of beautiful women, and they all have giant horse cocks. Scary, but fun. Like Nightmare Night.

The streets aren't too busy, which makes it a good time of day to dip your toe into exhibitionism. Even so, you deliberately take a winding path back home, testing your comfort level as you pass by groups of different sizes. You try to keep your greetings friendly, without being too seductive... but you can't help but put an exaggerated wiggle in your step, setting your butt to bouncing. To their credit, most of the passing mares gawk at you from a respectful distance, no doubt remembering the timid creature you were not twenty-four hours ago. But when you stop to let a cart pass on a street corner, you soon feel two pairs of hands settle into the flesh of your ass.

You jump forward and turn. Lotus and Aloe, two ponies who are quite comfortable putting their hands on people, are standing behind you with wicked smiles. "You've developed a handsome flank since the last time we saw you," says Aloe, the pink one. "Have we mentioned to you that we offer an especially luxurious flank massage?"

"You may have," you say. You honestly don't remember if they ever specifically mentioned that, but they've definitely offered you free-of-charge spa treatments since the day you arrived, promising "personal service" and "special attention." Their cocks, exactly equal in length, jut towards you, dripping pre onto the cobblestones.

"We go deep," says Lotus, curling her hand around your body to brush her fingers across your hips. "We know how to work every part of the flank. Inside and out."

You're tempted. Lying on a massage table, incense filling the air, getting your ass filled by two mares who specialize in pleasure... But as you consider it, you think of Lyra. Lyra, who took a risk on an untested spell to get to know you better. The mare who wanted you to be a part of her marriage. On a rational level, you know that sexual exclusivity is a foreign concept in Futaquestria; it would be almost unthinkable for Lyra to feel betrayed if you got your ass plowed by someone else. But you need to hear it from Lyra before you let yourself slut it up around Ponyville.

"That sounds good," you say. There's no point denying it; your underwear is getting tight, and Aloe and Lotus are eyeing the ridge of your erection through the fabric. Your cock isn't impressively sized in this world, but it's a reliable barometer of your arousal. "But I was on my way to see Lyra."

"Well, we won't keep you," says Aloe, with a bit of disappointment. "Come by anytime." They pass you by and one of them gives you a playful pat - not quite a slap - on the ass as they walk away. You feel a small shockwave of pleasure pass through you, and you feel your own cock begin to drip with pre. You suspect that Twilight enchanted the ring to make your ass not only big, but sensitive. You press a hand into your ass, and don't feel anything special - but there's no denying that pat on the butt was electric.

You hadn't been going in any particular direction before, but now you orient yourself towards Lyra and Bon Bon's house. Lyra's likely to be at home, practicing or recording, so you have a good chance of catching her. Your path takes you by the train station , and you hear the cheerful toot of the colorful passenger train arriving.

Didn't Pinkie say her sister was coming into town? Granted, she didn't say when, or how, so her sister might not even be on this train. Or any train. But out of curiosity, you look around the side of the station and watch ponies pour out onto the platform. There's a few mares who look like they could be Pinkie's sister; you're not sure how genetics actually influences ponies' color, but you figure you're looking for someone pink or rose-shaded. Whatever the case, you're certain you'll meet her eventually.

You're partially obscured by the side of the building, so most of the passengers don't notice you as they leave the train. But a few mares, all unfamiliar faces, turn to look as they pass. They don't quite know what to make of you, by their expressions; few ponies have heard of humans, even as cryptids, but your body works its inexplicable magic on them just the same. The mares are all drop-dead gorgeous, their tits perky at any size, their wide hips swinging as they walk, but somehow you're the one who's turning heads. Cocks emerge from sheaths, in all shapes and sizes, as dickmares size up the exotic creature in their midst. You adopt an aloof expression, hoping to dissuade them without having to turn them down explicitly, and it seems to work. The dickmares disperse, going their separate ways to fantasize about you in their hotel rooms and release their tension in private.

But as the platform clears, there's one mare, an earth pony, still standing at the far end, staring directly at you. She's practically monochrome; her coat is gray, and her hair is a dim purple. She stares at you through thick, dark eyelashes and an expression that seems almost bored.

But her dick isn't bored. It's standing at attention, spitting globs of pre onto the wooden slats of the platform. It begins to twitch, even as the rest of her body stays perfectly motionless. Her pre shoots farther and farther as the twitches grow in intensity, but her expression doesn't change. Experimentally, you step out from your spot behind the side of the station and walk towards the tracks, keeping your eyes on the gray pony. Her eyes follow you as you move, so she's not just staring into space, despite her blank expression.

Her dick jumps, and a splatter of cum shoots in your direction, landing just short of your shoes. Another twitch, and she paints the platform with another thick rope of jizz. Three more spurts of decreasing intensity, and her cock settles into being as motionless as the rest of her.

You don't quite know how to react to that. She didn't smile the whole time, or in any way acknowledge that she was having an orgasm, but hopefully she had a good time. You shrug, and turn to walk away.

And you almost bump right into someone. Actually, not just someone - it's the same mare who was just cumming all over the train platform. How did she get in front of you so quickly?

"I'd like to fuck you," she says. She steps forward, still expressionless, and the cum-dribbling tip of her cock kisses the fabric of your shirt as she draws close. "My name is Maud." You stare at her, nonplussed. Her boldness is unusual, even among the horny mares of Futaquestria. "Do you live in this town?" she asks, undaunted by your silence.

"Yes," you answer.

She takes a half-step closer, and your shirt bunches up as her dick pushes into you. The cum stain on the front grows as her cock, already ready for another orgasm, pumps out a slow, steady stream of pre. "You should live with me instead," she says. "When I go back home, you should come with me so that I can fuck your ass all day long."

There's something sexy about Maud's confidence, but her proposition is skipping a lot of the normal steps in a relationship. "I can't," you say diplomatically. "A couple of mares in Ponyville have already asked me to be their third."

"I see," says Maud flatly. She pauses, and though her expression doesn't change, you take this to mean that she's thinking. "All right," she finally says, "I'll have to make you fall in love with me."

You raise an eyebrow. "Excuse me?"

"I'll make you fall hopelessly in love with me," says Maud. "You'll forget all about those other mares once I seduce you, and then you'll be mine forever."

She's either completely, deadly serious, or she's deadpan joking. Or somewhere between those two extremes. You can't read her expression at all. But her body language is unambiguous, at least insofar as it consists of her shoving her hard dick into your chest, positioning her cock directly under your nose. Her musk, accentuated by the thick coating of precum, is almost subtle - you can't pick out a dominant flavor like you can with most mares - but it's powerful enough, when it's right under your nose. Your cock, which was already growing erect, shoots into full hardness.

"Well?" says Maud. Her eyebrows raise slightly. "Do you consent to be seduced until you become my devoted love slave?"

"Uh..." you mutter. "You know what? Sure. I want to see what you've got."

"Then it's agreed," says Maud. "Prepare yourself to be conquered."

"Can we go see Lyra first?" you say. "She's one of the mares I'm going to be partnered with. I wanted to talk to her before I go too far with any other woman."

"Yes," says Maud. "You can have one last moment to cherish the feelings you have for Lyra. Soon, you will love no one but me."

"Uh," you say, "Okay."

Admiring looks from local mares follow Maud as she walks hand-in-hand with you though Ponyville. She doesn't even live here, and she's managed to snag the human? Granted, hand-holding was the least of what they wanted to do with you, but it was more than most of them had managed to do.

"Well?" says Maud, tugging slightly at your hand, "Are you lovestruck?"

Holding hands is nice, actually. Your nervousness about giant pony cocks made you go without sex for the first few months of your time here, but you'd also gone without the more low-key aspects of being in a relationship. It's nice to just hold hands, just like it had been nice to simply have a conversation with Lyra.

You arrive at Lyra's door and knock with your free hand - Maud's still gripping your left hand, and she's surprisingly strong. You hear Lyra's footsteps on the opposite side of the door, and she swings it open. Your gaze, unbidden, shifts down to her cock and balls. Surprisingly, they're neither their normal size, nor are they at the absurdly swollen size they reached when she was pent up. Even though your cum-bloated belly shrunk down to normal overnight, it looks like her genitals haven't quite returned to their normal proportions. Her sheath seems thicker than normal, and her balls seem to have a few extra inches of circumference.

"Hey!" she says, her face lighting up. "Who's your fr- fr-" she stammers as her eyes make their way down your body and take in the thick, round shape of your expanded ass. "Oh Celestia," she breathes. "I... I thought I could hold it back, b-but... your ass..." Her cock slides out of her sheath, beginning to spit pre in your direction.

"It's really something, isn't it?" says Maud. "I don't really know anything about him, but I'm spending the day with him so that I can fuck his ass."

"Oh, c-cool," says Lyra, her body beginning to tremble, "I'm glad he's p-picking up some sexuAAAAHH... experience." Her knees buckle, and she slowly sinks to the floor. "Have f-f-fun..." Her cock reaches its full length - like her balls, her erect dick seems to still be bigger than its normal size - and as she kneels in front of you, her cock jumps and shoots a thick geyser of cum between you and Maud. She turns to you and, with unsteady hands, she reaches out and takes hold of your fat asscheeks, rubbing her palms on the soft flesh.

Once again she's incoherent, rendered totally helpless by her attraction to you, as her cock shoots its load over and over again. She actually managed to talk to you briefly this time, though - maybe having a date with you helped her to think of you as a person and not just a fetish object. You stand over her and watch her tremble, and moan, and cum for about thirty seconds, just in case her orgasm is going to come to an end. But it doesn't; she was able to hold it back for a while, but once her orgasm starts, it looks like it's still permanent until you leave her sight. You pull her hands off your your ass, and she barely resists, slumping to the ground as her cum continues to drench the grass outside her front door.

"So that's Lyra," says Maud, as you walk away together. "Meeting the woman I'm going to steal you from introduces a complex emotional layer onto my endeavor. But I remain undeterred."

"Really?" you ask, smirking, "You're able to put your emotions aside? You don't seem like the type."

Maud was silent for a moment - and given her flat expression, that silence could mean anything. "You're funny," she says. "All the more reason I have to have you for myself."

"If I'm being honest," you say, "I'm still down get my ass fucked, but I think I'm staying with Lyra in the long term. We're really just starting to get to know each other properly. That spontaneous orgasm thing happens every time she sees me, so it's hard to have a conversation."

"I see," says Maud. "Spontaneous orgasms are usually not so consistent, but they can be a problem for mares who are unusually excitable, like myself."

You nod. "Mmm-hm." Then, after a moment's pause: "Wait, you?"

"Yes," says Maud. "When I came all over the train platform, that was a spontaneous orgasm. As you pointed out, they make it difficult to carry on a conversation, so I've been holding them back ever since I allowed myself that first one."

"You can control them?"

"Yes," says Maud. "They've always been a problem for me, so I learned how to hold them back. It's second nature now, but you're making it more challenging than usual. See how pent up I am?"

She points to her ballsack and lifts it with one hand. You hadn't noticed before, but her nuts have swollen with pent-up cum. It's not nearly as serious as the almost-immobilizing growth that Lyra experienced yesterday, but it's signficant - her balls had been at mid-thigh before, and now they hang almost to her knees.

"Could you teach Lyra to do that?" you ask.

"Why would I do that?" she asks. "I'm going to win your love and take you away from Ponyville. You said you're the cause of her spontaneous orgasms, so once you're gone, she won't have a problem anymore."

Maud's logic is sound, if a little cold. You suppose that's what you should expect from her. "How about this?" you say, with a challenging tone. "I'll let you romance me, and if you don't manage to steal me away from Lyra, you'll teach her how to deal with her spontaneous orgasms."

"What do I have to gain by taking that deal?" asks Maud. "I'm already on a date with you."

"If you don't take the deal, the date's over."

"I see," says Maud. Once again, she falls into a silence that could mean anything. "Very well. I'll take your deal."

"Excellent," you say. "So what's your plan to seduce me? My last date was at a burger place, so you'll have to choose someplace even more romantic."

Ponyville's bowling alley isn't especially busy, this early in the day. You're a little surprised that it's even open.

You raise an eyebrow. "This is your idea of a romantic venue?"

"Stallions enjoy friendly competition," says Maud. "It will also permit you to watch my body in graceful motion. And for me to watch yours. The more I look at you, the more fluid and musk my genitals will produce, creating an environment that is ideal for seduction."

You shrug, and follow her to the front desk. Maud insists on paying, which seems appropriate. Neither of you bother with shoes; they're not compulsory, as you'd expect from a society where most people go nude at almost all times. When you take your lane, Maud picks out the heaviest ball available and hefts it with no apparent difficulty. Is she trying to show off? You're still not a hundred percent clear on what the gender roles are in Futaquestria, or what normal flirting would look like, but her strength is impressive. You test out a few balls, finding the first few to be uncomfortably light. You're stronger than you remember; looks like your work on Applejack's orchard has paid off in more than just awkward sexual advances. That reminds you, you need to swing by her farmhouse and let her fuck you silly sometime.

"Do you enjoy feeling big balls?" asked Maud, as you're kneeling by the racks, testing out a ball that seems like a good candidate. You turn to look at her, and she's standing over you, dangling her balls in your face. You catch a good faceful of her musk, and you feel your cock stiffening. Her balls seem a little bigger than the last time you noticed them; they're not bowling ball-sized, but they're getting there.

"Cute," you say, standing up.

"I was employing a double entendre," says Maud. "It sounded like I was asking about the bowling balls, but I was also talking about my testicles." You nod, giving her a look as blank as her own. "As a poet, I'm quite good at using language creatively."

"You didn't mention you were a poet," you say.

"I'm a geologist by trade," she says. "But I'm also a poet. Are sensitivity and creativity attractive qualities to you?"

"I guess so."

"Marvelous." Maud takes her ball, steps up to the line, and releases it in a smooth, graceful motion. She wasn't wrong about the advantages of the bowling alley as a dating venue; you'd never thought of it as a romantic place, but you'd never bowled in a world where ninety percent of people were naked women with perfect bodies. Her thick thighs and round ass are poetry in motion as she makes her throw, and when she turns to face you, with her fat cock tucked between her tits, and her swollen balls almost to her knees... she is pretty fucking hot. It doesn't hurt that she gets a strike on her first throw.

You look up at the screen, which displays a cheesy-looking animation of a bowling ball with arms and legs charging into similarly anthropomorphic pins. Just what is the technology level in Futaquestria, anyway? Nobody in Ponyville has a TV, as far as you know, but the bowling alley has these screens just for displaying scores and celebratory animations...

You stand and take your turn. You haven't bowled in a while, so you just try to toss it straight down the center of the lane. Your expanded ass gives you some trouble; each fat cheek sticks out on either side, making it impossible to smoothly swing your arm from back to front. You're forced to lean forward, sticking your butt in Maud's direction, in order to give your arm room to swing. It has the added benefit of giving Maud a little show.

It's a funny feeling, finally using your status as a sex god to attract women. Especially when it means getting penetrated. But it felt so good when Lyra was inside you... you're not quite ready to be a 24/7 slut, but going on dates and getting plowed at the end? That sounds all right.

And your wiles seem to be working When you turn around to look, there's a trickle of precum bubbling up from her slit and dribbling onto the linoleum. You don't plan on falling in love with Maud, but wiggling your ass for her is kind of fun.

You don't have much luck with the pins, though. Your shot goes wide, and just manages to knock down a couple pins as it rebounds off the gutter at the end of the lane. "Looks like you're not too good at bowling," says Maud, rising from her seat. "But I bet I can find something you're good at." Her tone doesn't sound seductive - it doesn't sound like much of anything - but it's clear what she means when she places your hand on your ass. Once again, her touch sends a shiver through your body. You're now certain that it's explicitly part of the ring's effect - looks like Twilight really wanted to make a slut out of you when she enchanted the ring.

"Here," says Maud, wrapping her arms around you, "Let me guide your body." Her ample chest presses into your back as she takes hold of you. You feel her heavy balls bumping the backs of your knees, and the base of her cock digging into the crack of your ass. She grinds herself into you softly, and a thick, hot drop of precum falls from the head of her cock onto your back. She wraps her hand around the back of yours, and you feel her strength guiding the motion of your arm. She lifts your arm back and holds it there, breathing hot, heavy breaths onto the back of your neck. You look to the left and right, and see mares and stallions frozen in place, watching the way Maud's body was intertwining with yours.

You wouldn't say that they look jealous, necessarily - sexual jealousy is frowned upon in Futaquestrian society - but they look like they want to be doing what you're doing. The mares in particular develop thick, dripping hard-ons, imagining themselves burrowing their shafts into your crack. A few of them seek out the next best thing to the sexy human, crossing over the lanes to put their arms around the nearest stallion. It's nice to be an inspiration.

Guided by Maud, your arm swings forward, and the ball rolls down the center of the lane, straight and true. She keeps her hold on you, grinding her massive shaft into your big round ass. The ball strikes the pins dead-center, knocking over all but one of them. The last one wobbles, spinning in a slow circle from the glancing impact it absorbed, but it remains upright.

But you're not so worried about the pins anymore. Your cock is straining against your black undies, dampening the front with precum. You're nowhere near as productive as the dickmares of Futaquestria when it comes to sexual fluids - even now, Maud's cock is dribbling a steady stream onto your back, soaking it with a wet, sticky layer. But your excitement is every bit as sincere.

Maud takes her hands off of yours and places them on your chest. Your shiver in her embrace as she moves her fingers down to your crotch. Her right hand slips underneath the waistband of your underpants, and her fingers begin to gently massage your shaft. Her other hand moves lower, stroking your balls with nimble fingertips through the fabric. "I want you right here," she says. Her voice is monotone as ever, but her fingers are deft, and gentle, and passionate as they go to work on you.

"Do it," you say, grinding your ass into Maud. "Take me."

"Your body is fascinating," she says. "You're not like any other stallion." She plants a kiss on the back of your neck. "I want to have you. I want to make my mark on you."

You feel heat building in your chest, riding up and putting a flush in your cheeks. "I want to get fucked, Maud." You slip your underpants down, and Maud moves her hand out of the way to allow them to slip to the floor.

"It wasn't my plan to fuck you this soon," says Maud, "But your body is irresistible. And you will fall in love with me when you feel my cock inside you." Your heart beats faster. You still don't plan on running away with Maud, but your feelings are pretty strong right now. You still don't feel quite suited to a world of casual sex - you've never had sex without being pretty serious about a relationship. But the way the dickmares of Ponyville look at you, it makes you want to be the town's biggest slut.

Maud backs up, giving herself enough space to maneuver the head of her cock into your asscrack. Her cock is well over a foot long, and its size would be intimidating if not for the six-footer you took yesterday. Maud's cock is going to fit, and it's going to feel good.

"I've always loved stallions with big butts," says Maud. The flared tip of her cock slowly separates your cheeks, painting your skin with her pre. "And your butt is the biggest I've seen. The smell of your skin is so different from any of the other boys I've fucked." She presses herself deeper, and you feel your butthole beginning to stretch around her. "What are you?"

"I'm a human," you say, between heavy breaths. It's already hard to speak normally, although Maud's voice is as toneless as ever.

"I've never heard of humans," says Maud. "If I may wax poetic for a moment, everything about your body is perfect and beautiful. Were you created from the dreams of horny mares?"

"M-maybe," you say.

She pushes herself deeper into the soft, pillowy flesh of your ass, and you feel her touch every inch of your inner passage. "Maybe you were created just for me," she says. "My cock seems to fit perfectly in your ass. Do you think that's true? Do you think that your beautiful body and your thick, soft ass were created solely to give me pleasure?"

All the strength is leaving your limbs as Maud pushes further into you. The magic that expands your ass is devious - Twilight must have enchanted it so that any mare, regardless of size, would fill you with almost unbearable levels of sexual sensation, a mind-melting sense of fullness that that was already driving wordless moans from your throat. And you don't doubt that Maud is feeling a perfect fit on her end - your ass, soft and yielding as it is, is gripping her cock in a tight embrace.

"Y-yes," you stammer.

"Yes what?" says Maud. Her tone is flat as ever, but she punctuates it with a thrust that makes her go hilt-deep inside you. Her hips slap into your asscheeks, and her balls swing forward and strike the back of your knees with such force that you fall forward, landing on your hands and knees atop the sanded wood of the bowling alley's approach.

"Yes," you croak, "I- I exist to give you pleasure. Maud."

She spanks your ass, repositions herself to take full advantage of your new posture, and begins to thrust, working her cock in and out of you in a slow, pistoning motion. Her balls slap rhythmically into your expanded ass as she pounds you. "Good," she says. "And you can't think of anyone else who you should pleasure, correct? Only me?"

"Only you." It's all you can think to say at the moment.

"Of course," says Maud. She pulls your asscheeks open, to permit herself to thrust deeper. You feel her cock distending your belly from the inside. You stretch painlessly, thanks to the ring's magic, but the sensation ramps up. Your eyes start to roll back, and your tongue hangs out of your mouth. "You're my toy," says Maud. "You're a special sex toy, because you're warm and you can wiggle your hips and tell me I'm beautiful. But you are just a toy, and you belong to me. Isn't that right?"

"Yes," you say. "You're beautiful. I'm yours." Your mind is nearly gone at this point. A tiny part of your brain remains online, able to repeat what Maud tells you to - but the rest is submerged in pleasure. Inside your ass, her cock pulses with each thrust, spilling more and more precum into you. She hasn't even cum yet, and you feel your stomach began to swell with her fluid.

"And if all that is true," she says, picking up the pace of her thrusts, "it would be fair to say that you love me." Her voice betrays no excitement, even as her thrusts come at an intense, fevered pace.

"I-I love you, Maud."

"You love only me."

"Only you. Only you, Maud. I'm yours."

"Wonderful," says Maud, as the first load of hot, thick cum escapes her cock. Her shaft bulges as cum rushes through it, and the additional pressure on your prostate sends you over the edge. You cum, shooting your load onto the pine floor in long, thick strands. For a long moment, you match Maud spurt for spurt, spilling your seed onto the floor as Maud pumps your belly bigger and bigger. You cum more than you ever had on Earth - something to do with inherent aphrodisiac qualities of Futaquestrian food - but Maud outlasts you easily, pumping you up with thick jets of cum as your own orgasm quiets down to a meager dribble.

You sink your hands into your stomach, feeling each spurt of mare-cum hit it from within. You're not going to become the immobile blob you were last night, but it's going to be obvious that you got fucked. Your midsection is already a wobbling mass of cumflated flesh, and when you waddle out of here, every mare is going to know that your ass is on the market now. If they didn't hear about your public escapades with Lyra, this will leave no doubt that the human is ready to get fucked.

Finally, Maud's cracked-dam burst of cum slows to a trickle, and she pushes off of your ass, filling you with one last erotic thrill as her cock slides out of you. You take your weight off of your hands and knees, and your cumflated belly supports you like a pillow. You're stuffed to the gills with Maud's hot, sticky love, and it makes for a wonderful bed.

Only...

"Maud," you say, as your head clears, "I know what I just said, but..."

"You're not really in love with me," says Maud. She sounds like she's taking it well, but she'd have the same tone if her heart was breaking. So...

"I want to make it work with Lyra," you say. "And Bon Bon. This was fun, but... I'm staying with them."

"That's fine," says Maud. "You said you loved me because I asked you to." She walked over to you and sat her ass down on your back. Your belly sank down slightly, but supported her weight. "While I was fucking you, you gave yourself to me completely. You cared for nothing but my pleasure. If you bring that attitude to every sexual encounter, you'll be a good lover to whoever you're with."

You're speechless. Maud has a point - and maybe you do have the right temperament for a sexually open society like Futaquestria, if that's what it took.

"I'll help Lyra to control her orgasms," says Maud, "But first I really should go meet my sister, Pinkie Pie. She's certainly wondering where I am."

"Wait," you say, a frown falling over your face, "You're Pinkie Pie's sister? You must have known that I knew who she was. Why didn't you tell me?"

"I admit that concealing that information was somewhat dishonest," says Maud. "I gazed upon your beauty, and I was blinded to the face of virtue." She paused. "I'm sorry, my inner poet got the better of me. What I mean to say is, your ass made me so horny that I couldn't think straight."

You roll your eyes. "Well, I can hardly blame you for that."

You listen through the door as Maud and Lyra sit, cross-legged, facing each other. "If you're ready," says Maud, "We will begin your training in orgasm control. My method is built around a form of meditation that I devised to address this specific problem."

"You invented a form of meditation, huh?" says Lyra. You can hear the grin in her voice. "Do you call it 'Maud-itation?'"

There was long, uncomfortable pause. Sweat prickled your forehead as the silence went on and on. Finally, Maud spoke.

"Of course I do."
