Whump.

A booming, earth-shaking footfall. You know what that means.

Whump.

The last one made the water in your glass ripple. This one makes the glass shake.

Whump.

Good God, how much bigger has she gotten?

WHUMP.

That one was right outside your door, and it shook the whole house. Okay, this you have to see. You stand from your chair and take a step towards the door...

"Hey, loser!" shouts Gilda, her booming voice barely muffled by your house's walls. "Heard you were back in town!"

"You know, you could just knock instead of shouting," you yell through the door. "Now everyone in Ponyville knows I'm a loser!"

Gilda laughs out loud. "Everyone else in this town is a bigger loser," she says. "And if any of them calls you a loser, I'll make sure they know it." There is silence between you, for a moment. "So you gonna let me in?"

"I don't know. Are you going to knock, like a proper guest?"

She responds by slamming her fist into the door, cracking the wood and busting the top hinge. Holy shit, did you actually make her mad?

"Geez, dude," she says, casually, "what'd you pay for this place? Pony carpenters can't even build something that holds up to a knock..." Wait, had she actually just been knocking? She was stronger than last time. Hesitantly, with trembling fingers, you open the door.

On the other side, you see... most of Gilda. You see as much of her as the door frame will permit, but her shoulders are too wide, and her head is too high, for you to see all of her. Her uppermost visible body part is her tits, two downy, umber globes straining against a small white top. They're bigger than they were last time you saw them, which you permit yourself to feel good about. The rest of her, though... is also bigger. Which is a mixed blessing. On the one hand, more Gilda. On the other hand... more Gilda?!

She bends at the knee, bringing more of her body into view. She has to be over ten feet tall now. Thighs thicker than your torso, biceps bigger than your head... and perhaps most ominous of all, her cock. It's tucked away in her fat, dark sheath at the moment, and you don't dare guess at its current full size. Her balls, swinging back and forth as she begins to contort her body to the shape of the door frame, are providing an almost unbroken stream of precum, interrupted by the occasional forceful squirt. You take note of the puddle of pre on your doorstep, as well as the dripping stain on the outside of the door.

Gilda has been steadily growing ever since you started hanging out with her. She didn't start out big - in fact, she was an inch shorter than you when you met, and she stayed that way for the first month you knew her. Then one day she just showed up at your house unannounced, three inches taller than you, and fucked your ass raw. And oh, how you'd been asking for it, those past couple of weeks. How you'd wiggled your ass in front of her, how you'd "accidentally" brushed your hands against her sheath, how you'd scooped her precum off the couch and tasted it, innocently pretending to believe it was "spilled frosting." She'd fucked you rough, given you exactly what you deserved for all your teasing.

And ever since then, she'd slowly been getting bigger. When you asked her about it, she initially denied it. "Naw, dweeb," she'd say, "Your furniture must be gettin' smaller." When pressed, she told you she was "eatin' right and workin' out," and that much seemed to be true. She spent loads of time at the gym and had herself on a protein-rich diet (she also had you on a protein-rich diet. From both ends). But that didn't explain why she was getting taller, and why it was happening now. You'd asked Rainbow Dash, but she was pretty tight-lipped. You suspected that Gilda shared the details of her sex life with Dash, and may have forbade her from gossiping with you.

After that, you'd gone to Twilight. Griffon biology wasn't her specialty, but what she did have was several big fuckoff books about it. She happily gave you every book on griffons that her library contained, confident that the information was in there somewhere. Gee, thanks, Twilight. A bunch of huge books. This is great, because everyone loves books as much as you do.

You didn't actually say that to her. Twilight is a good friend.

In fact, you spent the last two weeks with Twilight, as she showed you off to various foreign leaders. Yup, here's the human. Yup, he's from another world. Nope, he doesn't really do anything. And during the various train rides, you'd studied the books on griffons as much as you could. And you think you know why she's growing... but you're not ready to confront her right away.

"So is this some kind of prank?" says Gilda, as she works her right wing and shoulder through the doorframe. "You had someone make your door smaller while you were away?"

"Come on," you say, "You know you're getting bigger and putting on muscle. Half the time you even admit it."

"Don't know what you're talking about, lame-o." Her hand cracks the doorframe. "Oops." She works her head and her breasts through the doorway, compressing her tits with one arm as she squeezes them through. "Maybe you're just getting smaller and wimpier?" You roll your eyes, and Gilda manages to get her left wing through your door. Now completely inside, she flexes her full wingspan, and by God, she is a beast. Any time she wanted to, she could start punching holes in buildings, uprooting trees, and generally terrorizing Ponyville.

You actually feel your cock twitch as you consider that mental image. You imagine Gilda punching a building to pieces, grinding its remains into the dirt with her massive paws, and grinning proudly at you. As terrifying as her body is, you kind of want to see all that power running wild - and given Gilda's antisocial nature, acts of destruction naturally come to mind.

"All right," she says, "I got past your tiny prank door. I think you owe me a kiss for that. Bring it in, loser." She beckons you over, and you hesitate, taking a moment to consider her arms. If you're going to kiss her, she's probably going to pick you up. And if she picks you up, she might snap you in half. Even when she's asking for a kiss, her body is pure muscled menace, from her floor-shattering paws to the spiked collars on her powerful forearms.

"What's the holdup, little guy?" she says. Her voice becomes teasing. "Come on, I'll be gentle. You're no good to me broken."

In one giant step, she closes the distance between you and sweeps you up. Your muscles all tense, but she really is surprisingly gentle. Come to think of it, she's always managed to avoid hurting you, even as her growing body caused more and more property damage. That is, unless you count "getting fucked so hard you can't sit down" as a form of harm.

(In truth, that did get to be a serious enough problem that you sought some help for it. Rainbow Dash had asked you not to go to Twilight about it, and instead directed you to an herbalist who lived outside of town. "This lubricant will ease the strain," the herbalist had said, handing you a small jar, "and reduce your next-day pain.")

She lifts you up in her embrace, pinning you between the steely muscles of her arms and the soft pillows of her tits. You're fully wrapped up in her - you can't see or feel anything that isn't Gilda. Or smell anything else, for that matter. Gilda's scent drives you wild, and you're pretty sure she knows it - once she started growing, she began to swing by your house after the day's workout because "I want to shower, and your place is closer to the gym than mine." That excuse was barely true, and you're pretty sure she just did it because her post-workout sweat amplified her natural musk. She'd show up at your place and just hang around, delaying her shower, and before long every room in your cozy cottage would smell like the inside of Gilda' cleavage. And by that time, you were so worked up that she practically had you begging for a rough, sweaty fuck.

She brings her beak to your mouth, and you take the lead, pressing your lips against the hard surface. She has the sharp beak of a predator, and you both realized early on that it was better for you to do most of the moving when it came to kisses - she kind of just holds her beak open and gets her tongue as far into your mouth as it'll go. And today, that's pretty far. Her warm, slick tongue almost fills your mouth, and you do your best to grapple with it. Your dangling ankles get a precum shower as your kiss ramps up her excitement, turning her steady stream of pre into a fitful squirt gun. She moans into your mouth, leaning her face further into yours, and you feel your own cock straining against your pants.

"Mmm," she moans, breaking off the kiss and setting you down, "I'll bet you missed that, these past couple of weeks." You did, but it's clear that she missed it just as much. "Anything else you missed, you little dork? Anything Gilda can give you?" She runs her tongue hungrily over her beak.

You almost say "Holy shit yes, Gilda, I want you to destroy my asshole." That's what your body wants. But your heart is looking for something a little different today. "Actually," you say, "I want to try something new. You wanna go see a movie?"

Gilda is actually taken aback by this. Not offended, but... confused. "Come on, dweeb," she says, laughing nervously. "You've been gone for two weeks, I just want to chill at your place and forget the rest of this town even exists." She sits down on one side of your sofa, heedless of how her ass splinters the wood underneath, and pats the cushion next to her. "Just you and me, dude. That's all I want right now."

You're actually really flattered by that, and you consider giving in. She just came as close to saying "I missed you while you were away" as her personality will permit. It wouldn't be the worst thing to cuddle up with your big burly bird and let each others' hands travel where they may... but you have to stick to your guns.

"We can still sit next to each other at a movie theater," you say. "We can still pretend the rest of the world doesn't exist. We can still... have fun." You raise your eyebrows suggestively. "I'll make it worth your while, you big sexy monster."

With any luck, Gilda is completely thinking with her dick at this point, and she'll go along with your plan as long as you can deliver some "fun." She might consider it an indignity to have to interact with anyone besides you and Rainbow Dash, but blue balls might be worse - especially with the two coconuts she's packing down there.

And she really could stand to get out more. When she's not hanging out with you or RD, she's at home or at the gym. She makes her living providing her feathers to Quills and Sofas, which requires very little work on her part, so she has almost no excuse to socialize. And with Rainbow Dash spending more and more time with the Wonderbolts, Gilda barely even talks to anyone besides you in a given week. You feel a selfish little thrill at having a beautiful beefcake all to yourself, but making her a little more social seems like it's one of your responsibilities as her...

...well, that's the other problem. You've tried introducing terms like "boyfriend and "girlfriend" into your relationship and gotten nothing in return but Gilda's trademark name-calling. She really didn't want to have that discussion, but her position seemed to be "If I don't care what anybody thinks, what's the point of having a label?"

Well, you do care what people think. You want everyone in this town to see the caring, gentle woman that you see in Gilda - and you want them to see that the two of you are together. (To be honest, it's hardly a secret now - Gilda's lovemaking shakes the ground even more than her footsteps - but you want her to be open about it.)

Gilda groans and digs her fingers into the sofa's armrest - crushing it in the process - and picks herself up. "Fine," she says, with theatrical weariness. "But you owe me big time, okay?" She grabs the waistband of her tiny spandex shorts and pulls it upward, trying to cover up the fat bulge of her sheath. That might have been possible a couple weeks ago, but today the garment is only barely capable of containing her huge, toned ass and her massive nutsack, and it snaps back down to where it was before. She shrugs and steps toward the door, having made a token effort to stay decent for your public outing. She's technically being "indecent," according to the letter of the law, but it's highly unlikely that she'll catch any trouble for it - there's a lot of legal precedent that makes it hard for indecency charges to stick to anyone with "hyper-sized" endowments. Even if Gilda managed to cover herself up while she was sheathed, a hard-on would bust her shorts right open - and the law isn't going to punish her for something she can't control.

She works her way back through the doorframe. It's a little easier now, since she's widened it in a few places. You follow and shut the door as best you can, trying not to think about how you're going to get everything fixed.

The two of you walk in the direction of the movie theater. You know better than to try and hold her hand, but you keep close to her. Gilda scans the town as you walk, casting a suspicious gaze over the townsfolk. The ponies, for their part, seem pretty wary of her too. You're accustomed to warm greetings as you walk through town, but all you get now is a few looks of acknowledgment and concern. "Urgh," mutters Gilda, "This is why I never go out. All these ponies act like I'm some kind of freak."

"You know," you say, "They're mostly really nice, if you actually talk to them."

"Why would I talk to them?" she scoffs. "The way they look at me tells me everything I need to know."

"Well, you know that's not true," you say, patting her gently on her thigh. "When we first met, you thought I was looking at you funny." In fact, you'd caught her staring at you across the open market, where she was browsing the slim selection of meats that were on offer. She watched you go from stall to stall, her cock tenting her shorts more and more as her eyes followed you. She wasn't an amazon, back in those days, but her cock was still big, and your curiosity had gotten the better of you. You returned her gaze, and she immediately got up in your face, demanding to know what you were staring at. You'd told her that you were admiring her gorgeous wings - which was technically true, although your gaze had lingered longer on her generous bustline, her growing cock, and her bountiful ballsack.

The compliment caught her off guard, and the two of you started hanging out. You were surprised it took her a whole month to fuck you, since the sight of you had given her an instant boner, but Gilda had a hard time admitting that she wanted things from other people. Including sex. But if she'd opened up to you, maybe she could open up to the rest of the world too.

"Besides," you say, "They're no threat to you, Mount Gilda. You're bigger and tougher than anyone in this town."

"I'm not that big..." she mumbles. She's been defensive about her size ever since she started growing, but you can tell she doesn't mind it that much when you mention it. Her cock, which had calmed down once you proposed seeing a movie, starts to trickle with precum. "Besides, it's not me I'm worried about. What happens to you if they decide they don't want any freaks in their town? How are you gonna defend yourself?"

You don't know how to respond to that. Until this moment, you hadn't realized that Gilda saw the ponies of this town as a threat to you. She doesn't see the friendly greetings you get when she's not around. She doesn't see how you've been accepted. To her, it looks like the ponies are casting their suspicious glances at both of you.

"I think you've got the wrong idea about them, Gilda," you finally say. The movie theater comes into view, and you say "Why don't you get our tickets? Just talk to one pony, and we can go inside and have our fun."

"That wasn't part of the deal, dweeb," she says, bumping you with her hips. The force knocks you sideways, and you stumble to recover.

You step behind Gilda, and after looking around to make sure no one can see, you place your hands on the underside of her ballsack. "Come on," you say, moving your palms in slow circles, "Do it for me?"

Her hips buck involuntarily as you massage her fat scrotum, and she groans in defeat. "All right," she says. "Can't believe I'm letting a little shrimp like you push me around..." She looks over the posters. "So... what do you want to see?"

"Ooh, I don't know," you say, still rubbing your hands over her nutsack, "Maybe a sappy romantic comedy?"

Gilda snorts. "You're already pushing it, dweeb. You sure you wanna cross another line?" Her words are threatening, but you can hear the smile in her voice.

"All right, all right," you say. You take your hands off her balls and stand beside her so that you can actually see the posters. "How about the Power Ponies movie?"

"Pfft. Power Ponies? I knew you were tiny, but I didn't realize I was dating a baby."

"We're dating?" you say, looking up at her with a grin.

Gilda somehow manages to blush through her feathers. "Come on, you know what I mean," she grumbles. "Let's just see the dumb baby movie."

The two of you walk up to the cashier, a dark gray earth pony mare with a deep black mane, and you nudge Gilda to remind her that she's the one who needs to speak. "Uh, hey," she says, "Two adults or whatever for... Power Ponies."

"Oh," says the cashier, "Sure thing!" She looks like Gilda's making her a little nervous, but she takes your bits, dispenses a couple of tickets, and writes out a receipt for you.

"Oh, uh, hey," says Gilda, pointing at the thick brown quill the cashier is writing with, "I think that's one of my feathers." Even this tentative attempt at conversation makes her voice waver with uncertainty.

"What?" yelps the cashier. "I... I wouldn't steal someone's feathers! I got this at Quills and Sofas!" She holds the feather out, as if offering to let Gilda take it back.

"No, no!" says Gilda. "I sell my feathers to that store! I just meant that that quill came from one of my wings." The cashier relaxed. "Is it any good?"

"It's great, actually!" said the cashier. She slips the receipt through the window, and you take it. "It's a lot sturdier that pegasus quills"

"Heh," laughs Gilda. "It's nice to be appreciated. You're all right." She looks down at you. "Got the tickets?" You hold them up, and the two of you head for your theater. Luckily, there's double doors leading in, so Gilda doesn't break anything on her way there. You point to a spot in the back, and Gilda lifts an armrest out of the way so she can plant her giant ass on two seats.

"See?" you say to her, as you take an adjacent seat, "That wasn't bad at all."

"Tch," she says, "So one pony is nice to me. Doesn't prove anything." She leans down, looming over you. "So you really like the Power Ponies, huh?"

"Not really," you tell her. "I picked this one because it's been out for a month and a half, it's got lots of loud action sequences, and it's a school day, so... no kids in the audience. You see what I'm getting at, right?"

She smiles. "Oh, I think I do."

A few ponies filter in throughout the previews, but the theater remains mostly empty. As the film starts, you clamber up Gilda's legs, take a seat in her lap, and start rhythmically moving your butt back and forth over her sheath. "Oh man..." she moans, trying to keep her voice quiet... "You sure made me wait long enough..."

"I just thought it would be fun to do this somewhere else," you say. You start to grind your ass harder into her bulging sheath, and you feel her cock start to creep outwards, spitting precum all over the seat of your pants.

"Not just that," she says. "These last two weeks... I had nothin' to keep me going but memories of your hot little ass... I'm real pent up, dude."

"Don't just tell me," you say, "show me." You scoot your ass back as Gilda's cock grows, sliding out inch after glorious inch from her sheath. You pin it between your thighs and continue grinding into it, pressing your own crotch into her lengthening shaft. Her dick looks exactly like the pony dicks you've seen in this world - go figure - but, especially now, it's the biggest you've ever seen, thick and pink and oozing with pearly pre. It takes no time at all to reach a length where you can lick it, and you do so, scooping a mouthful of precum off of the flared tip. Her cum is less sweet than other sexual fluids you've tasted since coming to this world, with only a hint of sweetness beneath the sharp, salty flavor that dominates it. But that doesn't matter. You love the flavor because it's Gilda. The big, bulky bird you love, whose pleasure and smile is such a treat to you. You want to give her everything - and sometimes that means trying to make her more social. Other times - right now, for example - it means draining her fat nuts and filling your belly with her hot griffon seed.

Through steely determination, you manage to get your lips around the flared head of Gilda's cock. Once you're past that, her shaft is narrower - but you'll have to put in some work to get your mouth back off of her. You flick your tongue over her tip, licking more precum from her slit, and slide your mouth down her shaft until her tip hits the back of your throat. There's still plenty more inches to go, but that's as far as your mouth is gonna get. Through a tightly closed beak, Gilda lets out cute little squeaks. You know they'd be full-throated vocalizations if the two of you had any privacy, and it makes you laugh to think of the big give-no-fucks griffon girl caring so much about what other people think. You toy with the idea of making her cum so hard the she screams out loud, attracting every eye in the theater. Everyone would be looking at you, with your mouth around Gilda's fat dick, gulping down her cum.

But you couldn't do that to her. For a few minutes, you edge her, keeping her at the precipice of cumming. You've sucked her cock plenty of times, and by now you know what it feels like when she's close. When her twitches speed up, you slow down. It's torture for her; she digs her fingers into the armrests, then paws weakly at your body, wordlessly begging you to finish her off.

Finally, an action sequence begins on the screen, and you speed back up, lashing at her cock with your tongue. You can just barely make out a timer on the screen, ticking down... if you're good, you can get the timing just right. And boy, are you good. Just as a bomb goes off onscreen, you grab onto Gilda's balls and shove her cock as far into your mouth as it'll go. Gilda explodes, screeching in bliss - but her cry dies down before the building onscreen finishes collapsing, and no one turns to look.

Gilda's cum fills your mouth instantly. You gulp, frantically swallowing as much as you can, and only barely keeping up with the furious inrush of hot, thick griffon semen. There's no time to dislodge your mouth - the only thing to do is keep drinking. Her warmth begins to pool in your belly, and you feel the familiar sensation that Twilight blushingly described as "cumflation." Even a human is capable of expanding when a magical creature cums inside its body. Your stomach bulges, making space for the flood of cum, and you continue drinking down Gilda's load. Now that you've started to expand, you have all the space in the world for everything her balls can serve up, and you gulp it down greedily.

It takes a little under a minute for her orgasm to peter out, and you - cumslut that you are - milk the last dregs of it from her shaft. Finally, you remove your mouth from her cock and let out a satisfied sigh. "Yum," you say. "Cum."

Gilda runs her hands over your bloated stomach. She loves doing that; she's often fallen asleep while caressing your cumflated belly, cooing and murmuring about how sexy your bulging tummy was. When she's got a little more energy, she'll make you pose for her, or have you try and put on clothes, only to find they're hopelessly unable to contain your cum-filled belly.

"Mmm," she says, stroking your bare skin. "I made you so big, babe... I really filled you up, didn't I?"

"You sure did," you say. Between your legs, her cock starts to slump and recede into her sheath.

"You're my treasure," she says, whispering into your ear. "You know that, right?"

"Yeah," you say. In your head, you're saying But I wish you would tell me that all the time, instead of just after we fuck. Gilda's rough exterior disappears for a little while after sex, and those moments are nice. She's never a bad girlfriend - she's gentle and loving to you all the time, she just usually feels the need to dress her affection up in sarcasm and mild name-calling.

You sit on her lap for a while longer, as she rests her hands on your slowly shrinking belly. The first mystery of cumflation is how it happens at all, but the second mystery is how you just shrink back to normal size over time. The cum doesn't go anywhere, but eventually, it's just gone. Once your stomach is small enough that you can comfortably move, you hop off her lap and return to your seat. You put your arm on the armrest, and she covers it with her own, much beefier arm.

The two of you watch the rest of the film without any further shenanigans. Gilda occasionally leans over and tells you that some aspect of the movie is "dumb" or "for babies," but that's just Gilda being Gilda. She genuinely seems to enjoy the action sequences, at least - you see her eyes light up during the high-flying fight scenes.

She stands from her seat as soon as the credits start to roll. You consider mentioning that there'll probably be a post-credits scene, but that seems like it'd be a losing battle. Besides, she's been a good sport, so you hop out of your chair and follow her. You catch her attention and pat your belly, which still has a little extra bulge from her cum. "Oooh," you moan, mimicking a stomach ache, "too much popcorn..."

Gilda laughs. "You know, I feel bad. I already told you I was pent up, and that load you swallowed wasn't the freshest. The next one'll taste better."

"Well, that's too bad," you say, smirking up at her. "Because the next load's not going in my mouth."

Gilda laughs even louder now, shaking the floor with her mirth. "Oh, you're too good to me, dweeb."
