Berry Punch sleeps over with Cheerilee. Porn ensues.

Cheerilee has always been just a little jealous of her older sister. She would never admit to it, of course, least of all to herself, but spending her life so decidedly average and having an elder sister who was so decidedly unaverage has left her with a bit of an inferiority complex. Specifically relating to her body; where Cheerilee is a normal, somewhat frumpy mare with small breasts and a decidedly average figure, Berry Punch is a bombshell with tits bigger than her head and a three-foot long cock, complete with a set of hyperproductive balls capable of filling entire rooms with cum in one shot.

Cheerilee has always had ample reasons to be jealous of her older sister.

Reasons that Berry is very aware of. And feels that it's her duty to rectify.

Besides, she's always wanted to try breaking one of those enchanted condoms Carrot Top gave her to help deal with her morning wood problem. And hey, two birds, one stone.

WARNING! CONTAINS ANTHROS, FUTA, HYPER, INCEST, COCK GROWTH, COMICALLY EXCESSIVE AMOUNTS OF CUM, CONDOM BREAKING, AND PROBABLY A BUNCH OF OTHER WEIRD STUFF

Pent up as all fuck

“I need a place to stay for, like, a week.”

Cheerilee bit her tongue. Her first instinct was to berate her sister for getting herself evicted – again – but Berry was her sister, and it wouldn't be fair to just assume. Still, she couldn't just blindly say yes. “Why?”

Berry Punch put on a show of exaggerated pouting. “Aw, what, you don't trust me?” She grinned. “Don't worry, I didn't burn my apartment down again. They're just fumigatin' the building and shit so I need a place to stay unless I wanna breathe bug-killin' gas all week long.” She belched. “Phew, 'scuse me.”

Cheerilee's nose wrinkled. “Berry, are you drunk?”

“Well, yeah, duh. I don't get to drink all that much ever since Pinchy happened.”

“Uh huh.” Cheerilee maintained her air of disapproval, but she had to admit that, ever since Ruby had been born, Berry had actually made a concentrated, mostly successful effort to sober up. “Where is Ruby anyway?”

“Stayin' over with some friends. I figured it wouldn't be fair to dump a kid and a me on you. Oh hey, speaking of which, I've got gifts!”

“How is that related to Ruby not being here.” Cheerilee felt that she already had an idea as to what the answer would be, but she felt the need to ask anyway.

“Adult gifts~” She reached into her purse and pulled out – oh god.

“Condoms? Really? What exactly do you expect us to be doing while you're here?”

“Incest!”

“No! No incest!”

“But incest is wincest!”

Cheerilee groaned, clenching her eyes shut and pinching the bridge of her nose. “Berry...”

Berry threw up her hands in a pacifying gesture. “Hey, kidding, kidding. Condoms are for me. I get hella bad morning wood.” She made a vague drunken gesture that maybe could have been an indication of size if you were to squint. “Also sometimes I sleep-cum. And I don't wanna make a huge mess of your house again. Anyway, hold on, I've got your actual gift here...” She rummaged through her purse again.

Cheerilee winced. “Ugh. Please don't remind me of that. You filled a whole room with... fluids.”

“Ha! Yeah, that was fuckin' awesome. Kinda pissed off the doctor when he realized I wasn't actually impotent but fuck it, by then I'd already got the fertility prescriptions and anyway, it was totes worth it.” She pulled out a small package, wrapped in tacky, brightly coloured paper and topped with a bow. “Here!”

Cheerilee awkwardly took the package from her sister. “This really wasn't necessary, Berry.”

“Pft.” Berry made a vague, dismissive gesture. “I figure that if I'm gonna be dumping my sorry ass on you for a week I should at least do somethin' to make up for it. Like naughty not-safe-for-Pinchy gifts!”

“Berry! You said that was a joke!” Cheerilee's face flushed with embarrassment.

“I said the condoms were a joke, sis.” She waved her hands wildly in what was probably an attempt at a defensive gesture as filtered through several layers of Drunk Berry. “I swear it ain't like a dildo or somethin'. I figure you prolly have your own dildos and anyway I don't know what kinda shit you're into size-wise and I figured callin' you up and going 'ey would you rather a four or five foot dildo' would prolly give it away.”

“Berry, not everyone is a size-queen.”

“Yeah, sure, keep tellin' yourself that. You and I both know that's just a bullshit cultural standard 'cos most actual stallions ain't got shit on ponies like me~” She made another gesture, this one much less vague; she was pointing at her substantial bulge. With both hands, of course.

Cheerilee had, over the years, gotten very good at not looking at her sister's cock, nor at her head-sized breasts. There were, of course, ways that Berry could hide her package, but she'd never bothered – “too expensive” was the excuse she continually trotted out, but Cheerilee was fairly certain that she just got off on being stared at. Damned if it didn't work, though. A Berry with a pair of yoga pants and a tank top, neither of which even remotely big enough to contain her assets, was a Berry it was hard to look away from. Her tits strained, squeezed, deformed and flattened, oozing out of the sides and top along with just enough of a hint of dark purple areola to not get her arrested for obscenity. Her pants looked like she'd stuffed several watermelons into them, stretched and warped beyond repair. It was only years and years of exposure that let Cheerilee ignore the spectacle as easily as she did.

“And I know I ain't the only one. Guys are just jealous that us ladies, when we've got dicks at all, have got bigger ones'n they do.”

Of course, Berry didn't make it easy on her.

“Berry stop talking about your fucking cock or I swear to Celestia I won't let you stay here.”

“Fiiiiiiiine, ya' big baby. Anyway, open your present!”

Cheerilee sighed, and then tore open the gift. “Oh. You shouldn't have.” She did her best to fake an enthusiastic smile as she held up the gift; a negligee, lacy and white and decidedly see-through. Far sexier than any nightwear Cheerilee owned – or any clothing she owned in general. And, along with that, there was a bra – black, similarly lacy, and very clearly designed to provide support and nothing else. The cups specifically stopped roughly where the nipples would be, effectively leaving everything important exposed. As for the panties, they matched the bra both in that they were black and lacy, and in that there was a fucking enormous hole right where what panties were typically supposed to cover would be were somepony wearing them. “I'll treasure them always. Now come on, it's almost dinner and I need to figure out how to deal with suddenly having a guest.”

“Put 'em on!”

“what no.”

Berry grinned. “Come ooooooon, lil' sis. Ain't nothin' I haven't seen~” Her grin turned lascivious, her eyes half-lidded, and she licked her lips a bit. “'sides, just think'a givin' all of Ponyville a show. I picked that shit out specifically to show off every inch possible of your sexy body.”

“Berry, I'm not sexy.” Cheerilee winced as she said it, because she knew it was true. Compared to her elder sister, she was downright frumpy. Short, skinny, and where Berry had a three foot cock, Cheerilee was decidedly just a plain, average female. She had respectable curves, at the least – good sized tits, decent hips and ass – but they paled in comparison to her elder sister's.

“Pft, says you. I'll betcha' there's plenty of folks out there wanna bone the fuck outta your tight little ass.” Berry took a step forward, and then another, slowly invading Cheerilee's personal space. “Besides, just think how fun it'd be. Mmmm, just thinking about you 'n me, showing off and having some fun, right here and now? 's got me horny as fuck.” She pushed her body tightly against Cheerilee's, giving her younger sister a small peck on the cheek that turned into a lick.

“Berry not in public god fucking dammit.” Cheerilee shoved Berry away, removing the increasing pressure from her body. She sighed. “Okay, look. I'll wear them to bed tonight. Will that make you happy? And stop with the...” she shuddered. “The you-know-damn-well-why-I'm-objecting-to-it?”

Berry sighed. “Fiiiiiiiiine, be boring.” She pushed past Cheerilee, through the doorway into her modest home. “And don't worry about dinner, 's on me. Side effect of havin' a kid – cooking somethin' every day means you get a lotta practice at it, y'know? Hard to not get at least a li'l good at it after a few years.”

Cheerilee sighed. She was going to have to deal with a whole week of this. Still, she'd dealt with living with Berry for sixteen years straight. A week was nothing, especially considering that this time Berry would be in the guest room and not sharing the same space as her.

Or at least, that's what she kept telling herself as she tried her hardest to ignore the loud, drunken rendition of the chorus – and only the chorus, over and over again, interspersed with uproarious laughter at nothing in particular – of Mares Just Wanna Have Fun coming from the kitchen.

Cheerilee winced. It was going to be a long week.

Early morning sunlight streamed lazily through the bedroom window, enveloping Cheerilee in its warm glow. She groaned, burying her face deeper into her pillows. It was summer, dammit. The one time of year she got to actually sleep in, and she was going to take advantage of it. She didn't care that her window was perfectly positioned for the sun to shine directly into her eyes. She didn't care that it was too hot for the amount of covers she had on – especially factoring the lingerie that she just couldn't bring herself to not wear. And she certainly didn't care about that strange, heavy sensation between her legs. Nor the fact that something large and hot and very, very, very hard was pressing itself into her torso.

She groaned again. Whatever it was, it was uncomfortable to lie on top of it. Especially with how fucking hot it was. She flopped around in bed, kicking the covers off of her and turning over onto her back. The position was marginally more comfortable – at least it was less sweltering – but the weight was still there. If anything, it was worse than it had been. It pressed down on her torso, shoving her tits aside with its girth, reaching up past her neck above her head and pressed into the headboard of her bed. She shoved the thing away from her, and with a pop, the pressure was gone. The weight and warmth was still there, but at least it wasn't pushing into her face anymore. And beyond that, it felt like there had been a release of pressure. If she didn't know any better (and she did) she would have thought that she was feeling the shaft, pulsing bigger and bigger and bigger now that the headboard was no longer impeding its progress.

She groaned – more of a moan, really – and her sleep-addled mind began to register that something might be unusual about this situation.

“Mornin', sis! Lookin' good!”

Cheerilee threw a pillow in the direction of her sister's voice. “fuggoff iss too fuggin early.”

“Early to bed, early to rise, makes a pon' healthy and wealthy and wise! And dang, you're lookin' healthy as fuck. 's gotta be four feet already. 'n still growin', t'boot. Fuckin' unf.”

Cheerilee frowned. Her mind awkwardly attempted to process what her sister was saying. “Four feet of what?” She reluctantly resigned herself to not getting any more sleep this morning, and opened her eyes.

And her vision was filled with cock.

Her cock.

“... Dammit, Berry.”

“Happy thirteenth birthday, sis!” Berry grinned widely, squirming with giddy joy. “Man, you've got no idea how long it took to save up to be able to buy that. Well, I guess you do 'cos it's a thirteenth birthday present and you're thirty four years old and you're a teacher so you can do the math I guess? But yeah, no unnecessary spending for twenty one years, but it was sooooooo fuckin' worth it.” She hopped into Cheerilee's bed, kneeling at the foot of it, like she was prostrating herself before the now four-and-a-half foot shaft. “Look at you! You're enormous~”

Cheerilee stared in cold terror at the pale purple shaft before her, trembling and throbbing and growing. Why was it still growing? It was already bigger than any of her students, certainly bigger than Berry's own prodigious package. Enormous was an understatement. It was ridiculous. “berry what did you do.”

“I told you, 's a gift! The underwear was enchanted!” She threw up her hands. “Surprise!” She leaned in closer, grasping the monolithic pillar of flesh with both hands, sending a piercing spark of sharp arousal blazing through Cheerilee's spine. “I mean, you're so normal, which isn't bad, but then you've got me and my tits and my cock and, like, I mean. I dunno.” She stroked the pulsing length, drawing a quiet squeak from Cheerilee. “I guess I feel guilty? 'cause, I mean, me just bein' around gave you a complex. And don't say it didn't 'cos you know that's bull. You're all weird about sex 'n stuff and it's prolly my fault so I figured that, you know. This'd make it up to you.”

Cheerilee opened her mouth to respond, but all that came out was a strangled gasp as Berry licked her cock, slowly, from the middle to as close to the head as she could reach. “Mmm, delicious. Gotta say, though, you're a lot bigger'n I thought you'd end up being. And yer not even done yet! Guess I outdid myself. Heh. Oops.” She resumed licking, this time moving downward towards the base. “I probably didn't even need to slip those fertility drugs into your food last night.”

“You slipped whanghhhh.”

“Yep! I mean, unless the guys I bought the underoos from cheaped the fuck out on the custom features you should already be four times more productive than me, but I mean that's so boring. Why the fuck would you cap the production so low? That's nowhere near what we're gonna need to get outta you, sis.” She reached the base of Cheerilee's cock, stopping to snuggle her balls. “We're talking fucking exponents, here. Cumshots on a geological scale. Mmm, one second.” She leaned back, the sudden loss of contact drawing another moan from Cheerilee. “Gonna wanna hold that shit in, sis. Don't want you to cum until we're good and ready. Speaking of...” She reached behind her back, producing seemingly from nowhere a pair of small, plastic packets. “Condoms!”

Cheerilee didn't respond. She wanted to slip in a quick death threat, but her brain was beyond rational thought at this point. She weakly thrust her hips occasionally, and let out some weak moans. She did not, pointedly, actually touch her own shaft. “Prolly 'cos there's still a li'l bit of you aware enough to wait until you've got one of these bad boys on before cummin' all over the place. Love these things, bee tee dubz. Got 'em from Carrot Top, they're magic. They fit any cock, they let any cock fit any vag, and most importantly, you can cum and cum and cum and they'll barely fill up. Of course,” she tore open one of the condoms, “as far as I know they ain't tested it up to anywhere near the kinda output you're gonna have by the time we're done here. But, hey, that's what we're here for, innit?” She licked her lips and patted her own cock, already slowly twitching to life. “First gonna get my own on, tho. You wouldn't believe how pent up I am. Been holdin' off for a fuckin' week to get ready for this shit – and if what I've got in mind works, this fucker's gonna be kinda pointless, but hey. Better safe than sorry, right?” She pulled the condom wide and slipped it over her hardening member, which was absolutely dwarfed by Cheerilee's now five foot long cock.

She gave her cock a few luxurious strokes through the condom, slowly working it to full hardness. “Man, these things though. Can't understate how fuckin' great they are. Like, right now? Totes don't feel like I'm wearin' a condom. All'a the sensation, none'a the mess. Awesome.” Her penis, by this point, had reached full hardness – and was only just barely longer than half the length of Cheerilee's still-growing monster. “Should be alllllmost done with growin', sis. Then we get to move on to step two! In the meantime, I gotta get some shit ready. Try not to cum before the show begins, unless you wanna ruin your bedroom early~”

She tore open the other condom, adeptly manoeuvring herself around her three foot cock with the practised ease of someone with a lifetime's worth of experience in dealing with opening a condom around a cock that reached above your head. She worked methodically and carefully, but at the same time swiftly, producing a bottle of what appeared to be lotion from the same aether the condoms had come from, screwing off the lid and upending it into the condom. “Special herbal lube blend I bummed off of Zecora. You're gonna like this one if it does what she says it does~”

Carefully, she moved the lube-filled condom up and over until it was level with Cheerilee's flare. “Looks like you're just about done with growin'. Gotta say, you look really nice with a pony-sized hunk of meat, sis~” Berry deftly upended the condom onto Cheerilee's cock without spilling so much as a drop of the lube, before slowly working it down Cheerilee's length. It took Berry a full minute to reach all the way to the monolithic pillar of flesh's base, the condom effortlessly containing the entire thing snugly and comfortably.

“Now for the fun bit. Here, eat these.” Not waiting for a response, Berry shoved a fistful of pills into Cheerilee's face. “Can never have too much production! Come on, swallow for your sister~” She reached behind her back, pulling out a rolled up sheet of paper from nowhere. “And, of course, a little custom spell. Would'ja believe I got it from Princess Cadance? True story, went to Twilight a few months ago to let 'er know 'hey, I'm gonna try and break one of those magic condoms n' shit, you're gonna wanna get stuff cumproofed in advance cuz there's gonna be a shitton of cum' and a few weeks later I get this in the mail along with a note saying 'hey, this is the Princess of Love and I want in on this shit.'” She unrolled the scroll, and it began to glow a pale pink. “'s got some magic pre-cast, all you gotta do to activate it is be a pony 'n read it out loud. Speaking of which,” Berry placed one hand on Cheerilee's cock, the other holding the scroll up as she read it; “'I could come up with suitably magic words for this shit, but fuck it, it's a spell for transferring the orgasms you have into a cum productivity boost for another pony and then taking that end result and multiplying it by itself a few times. Let's not get pretentious, this is for sex and only for sex. Now have some fun with it and bust some fucking condoms for me~' Dawww, ain't she sweet? Now it's time for the show to really get started.”

She licked her lips, and then began to jerk off. Slowly, languidly, she massaged her cock. “Just bear in mind that I'm gonna be basically cumming directly into your balls here. And each time I cum I'm gonna be making how much you cum when we finally get to that bit that much more. And – ngh – I'm pent up too, remember? So I'mma be comin' a lot. Nggggggghfuck.” She bit her lip, her strokes picking up their pace, becoming more erratic and frantic. “Oh, and – gnnnngggggfuck yeah – and I've also had 'bout as much 'a them fertility drugs as you soooooo you're gonna wanna hold on tightly to somethin' 'cause you've got a lot cummin' your waaaaaayyyyyy~”

Berry convulsed, her hips thrusting and her balls pumping and twitching. Her arms fell to her sides, doing their best to support her even as her strength left her. Every muscle, every fibre of her being was dedicating itself to her orgasm. Her shaft pulsed, enormous bulges of seed travelling up its length where they didn't erupt from the tip. Not so much as a droplet of precum escaped from her urethra. If Cheerilee's mind were a bit more coherent she would marvel at the surreal image of Berry cumming as hard as she damn well could and yet somehow shooting a complete blank.

However, Cheerilee wasn't in the state of mind to marvel at anything. The only thing going through her brain was crippling sensory overload. Her body danced on the edge of orgasm, tantalizingly close to that ultimate release yet constantly just short of actual climax. Something, some nebulous force was holding back her orgasm. Like a dam blocking a torrential river, mighty and immovable but ultimately nowhere near enough for the building building building wall of water constantly pushing at it. Already cracks were beginning to form, thick spurts of white filling the reservoir that topped the condom. Tiny little trickles bursting through the slowly failing structure, a mere hint of the ocean waiting to burst free.

Cheerilee's hands moved on their own. Slowly, they traced their way across her legs, her hips, settling on her balls. Just the slightest brush of her fingers against the taut, overfull cumsacks felt like electricity running up and down her spine. They were so hot, and big. Bigger than her tits, bigger than Berry's tits. They throbbed and churned and rumbled like distant thunder, like a goddamn earthquake.

And they were growing. Pulsing bigger and bigger and bigger with every thrust of Berry's hips. They spilled over her thighs as they swelled bigger and fatter and fuller, heavy with their titanic load even as it compounded upon itself, taking Berry's own cumshot and multiplying it against itself endlessly. Cheerilee moved instinctively, hefting herself upright while she still could, and then flopping over forward to rest on top of her growing cum factories instead of underneath them. She knelt on top of them, like they were a dark purple beanbag chair and not a part of her. Celestia, they were growing so fast. She could hear her bed creaking and groaning in protest at the burden it was being made to bear.

Cheerilee gasped sharply as Berry decided now would be a great time to clumsily climb up with her. “Ahn!”

“Yeah, sorry, figured I should do this sooner rather'n later. Don't know quite how big they're gonna get, 'n this is prolly the safest place in your room right now. Definitely safer'n under 'em.”

Cheerilee groaned.

“Anyway, this's pretty much it. Now all we do is wait for mount Cheeri to erupt.” Berry stood shakily – sober though she may have been, she didn't exactly have the most steady footing at the moment. “Hopefully it doesn't take too long 'cause I'm sure you've got other shit you wanted to do today.” She gave up on attempting to stand, and let herself fall, landing hard on her cushiony ass.

Cheerilee groaned.

“Ooop, sorry about that. Prolly should have done that a bit more gently, kinda forgot this isn't a waterbed I'm sittin' on.” She almost, almost patted the overfull balls beneath her, but thought against it. “Though, I mean, I guess it prolly wouldn't actually be that bad of an idea. Might hurry things along at least, though I don't wanna rush things too much.” There was a loud crunch as Cheerilee's bed ceased to be beneath her.

Cheerilee groaned.

“Woah!” Berry scrambled out of the way of another jet of pre-cum filling the condom with a blob as big as her – and that was after the condom's mass reducing enchantment had its way with the stuff. Who knew how much was actually there. Probably a lot, and she still wasn't cumming yet. Though it couldn't be much longer until she was. Her attempts to move out of the way only made the spurts of excess production come with even more frequency and volume. It was enough to make any cumshot Berry'd had in her life look like nothing. Hell, it was enough to outmatch a full day's worth of masturbation or more, and this was only pre.

Still, it might as well have been an orgasm. Huge, copious jets of fluid were inflating the condom like it was a water balloon strapped to a hose going at full blast. Which was a very apt metaphor since it was just barely a metaphor. Cheerilee grabbed her six foot shaft, her hands completely inadequate for the job of masturbating the veritable tree trunk of a cock she had grown. It was disproportionately large on her slender, feminine frame. It would have been comical if it weren't so hot. Both figuratively and literally – just being as close to it as Berry was felt like sitting next to a goddamn furnace. She couldn't imagine how hot it was to touch, though Cheerilee hardly seemed to mind. She was masturbating in earnest, with a furious determination that wasn't quite enough to make up for the vast size difference between her and her shaft.

“Here, lemme help you with that.” Berry moved forward as best as she could considering how much the ground beneath her was lurching violently beneath her legs. She shoved the enormous well of cum aside, giving herself room to crawl up onto her sister's cock. “You know, I was originally intendin' to finish this off with a titfuck, but hoooooo boy, did you exceed my expectations, sis. You may be my younger sister, but you sure as shit ain't little. I guess you were just always meant to have a giant slab 'a meat between your legs, eh?” She straddled the cock, wrapping her legs around it as best she could – it was just thick enough that her feet could touch on the other side. “Anyway, that's outta the question, considering how big you've gotten. Buuuuuut,” she purred. “I figure that I ain't enough of a quitter not to give 'er the ol' college try, eh? How's a full body titjob sound to you?”

As prodigious as her tits were, Berry noted that even they were comically inadequate for the job at hand. Even with her arms and legs wrapped tightly around Cheerilee's meat, pulling herself up and down and up and down, squeezing and releasing, it was just barely enough to cover a fraction of the available ground. She barely noticed as the evergrowing bulge of overstuffed condom flopped back, covering her body like a pillow full of hot water. She could feel her own flaccid cock stirring to life again from the stimulation, pressing against Cheerilee's own, much bigger member as it attempted to rise to attention. The flat head prodded insistently at the overfull ballflesh below it.

And Cheerilee fucking groaned.

Celestia had always, when she could help it, been a late riser. She hated summer for that reason – yes, she got to stay up later, but she had to get up earlier too, and that was never fun. It had only been a few hours since she rose the sun and already she was on her fifth cup of coffee, of many more to come.

“Honestly, Auntie Celestia, you would probably be more of a morning person if you drank less coffee.”

“Mrf.”

“Especially considering how much tea you drink, too. That's a lot of caffeine for your body to process and it's only gonna make you feel even worse when you come down.”

“Princess Cadance,” Celestia replied. Her voice was calm and clear and did not betray how much of a wreck she looked to be at all. “If I had known how much you were going to complain about my caffeine addiction, I would not have invited you to visit. Which, by the way, was your idea. You were not very subtle about wanting to visit, and if you want me to invite you next time you decide you really want an excuse to stop by Canterlot again, you're probably going to want to drop the subject of coffee and tea. Also, baked goods and pastries.”

“Okay, yeah, fair enough.” Cadance shrugged. “Is it really so unusual for me to want to see my dear, sweet Auntie Celestia?”

“Yes.”

“Well, then, maybe I wanted to see my dear, sweet brother?”

Celestia raised an eyebrow. “Cadance, no one wants to see Blueblood. I think that, were it possible for him to do so, Blueblood himself would never lay eyes on Blueblood for the rest of his natural life.”

“My dear, sweet sister-in-law?”

“She lives in Ponyville. Try again.” She took a dainty sip from her mug – it was large and white with “World's Best Sister” written on it in big bubble letters. “Or you could just admit that you're up to something lewd. Again.”

Cadance placed a hand on her chest in mock-outrage. “Well! I see now how little you think of me, dear Auntie.”

Celestia, again, raised an eyebrow.

“Okay, fair. If it helps, I promise you that I have no intentions of doing anything particularly lewd while I'm visiting. I even left Shiny behind, so you know I'm serious!”

“A lack of your husband hasn't stopped you before.” Celestia placed her mug back down on the table and grabbed another muffin, shoving the whole damn thing into her gob unceremoniously. “Really, you've never been good at subtlety, so it's best if... you... Do you feel that?”

“Feel what?”

Celestia steadied herself, swallowing her muffin. “That... rumbling. It feels like – is that an earthquake?” It had been quite a long time since there had ever been an earthquake in Equestria, and longer still since there had been one felt in Canterlot of all places. It wasn't her imagination, either – she could see ripples moving through her coffee, and Cadance was gripping her chair and looking mildly concerned.

“Oh, dear.”

“Cadance, dear, what the fuck did you do?”

Berry was surprised at how easily she could tell that Cheerilee was actually cumming. Her output before had been impressive enough, and when coupled with her frantic thrusting and pumping and moaning that she honestly was surprised at how dramatic the difference was. Cheerilee screamed in rapturous joy as her ultimate release finally came, along with a spurt so enormous and forceful that the condom broke through the ceiling of her room – and, indeed, Berry could see sunlight filtering lazily in through the resulting hole. And the second jet was, somehow, even bigger. Berry couldn't help but feel humbled at her own paltry-by-comparison releases, even if she was at least partially responsible for a part of the level of production her sister had attained, both indirectly and, thanks to Princess Cadance's spell, a little bit directly as well.

And this was after the condom worked its magic. Under normal circumstances, it would have compressed the volume to something manageable. These were hardly normal circumstances. Berry could feel the pressure and heat of the cum-bubble enveloping her almost entirely, pressing her whole body tightly against Cheerilee's hot, rigid cockflesh. And this was just a fraction of a fraction of a fraction of the unfathomable volume that was actually being released. Each jet enough to make the room-filling cumshots Berry was capable of look like tiny droplets of water in a vast ocean. And still the damn thing held firm. Clearly, Berry had underestimated the enchantments.

Of course, there was no way they could hold up forever, and Cheerilee showed no signs of slowing down any time soon. She grasped her shaft firmly with both hands, not caring remotely how woefully inadequate they were for the task at hand. Her hips jerked wildly with each jet of her orgasm. She didn't speak – she was well beyond the point where she could put together coherent sentences. Just moans and cries of ecstasy, reverberating through her increasingly cramped bedroom. Something was going to have to give soon, or else they would find themselves slowly smothered to death between the endlessly expanding condom and Cheerilee's overproductive sac. It was a race against time to see which would break first; the condom, or the ponies.

The faint sound of straining latex was a good hint as to the inevitable loser of that race. Berry could feel it pulsing and wriggling behind her, slowly but surely being pushed to the point of bursting. Success was so close that she could taste it. Quite literally, the air so saturated with Cheerilee's musk that they might as well have been breathing cum. The atmosphere was so charged with need that Berry found her own member aching with it. She had already cum once, quite copiously as evidenced by the effects it'd had on Cheerilee, but she had never been satisfied with just one orgasm.

And fuck, Cadance's enchantment was probably still going. It certainly couldn't hurt to give things another little push.

The cum-bubble had thoroughly enveloped her body, pressing her tightly enough against Cheerilee's tree trunk of a penis that she couldn't move. But, thankfully, she had gotten very good at getting off hands-free over the course of her life. The friction of flesh-against-flesh helped, but even without it, Berry knew she would be cumming eventually. Just the situation alone was enough for her to crest higher and higher on waves of arousal. The friction just expedited the process, pushing her over the edge slightly faster than otherwise.

Her second climax was, somehow, more intense than the first one. Her mind went blank, her vision went white, and she came. Like before, her cock convulsed and pulsed as gallon after gallon of her seed was pumped through it. And, like before, not a single goddamn drop escaped. Berry's mouth hung open in a silent scream as she experienced the single most intense blank shot that she, or anypony else, had ever experienced.

Of course, when placed beside Cheerilee, there might as well have been nothing anyway. Her sister’s tongue hung out of her mindlessly grinning mouth in stupefied rapture. “Yesssssssss,” she hissed as she felt her already enormous balls lurch beneath her and begin to grow again, fed by all the cum that wasn't coming from Berry's orgasm. “Moooore,” she moaned in as rough an approximation of speech as her lust-addled mind was capable of. And more she got. Even as she came and came and came, her balls quivered and pulsed and swelled, bigger and heavier and fuller past the point of bursting as they prepared her next load. Testicles big enough to completely smother her bed became bigger, rapidly filling up the room and showing no sign of stopping.

There was a deep, primal groan. At first Cheerilee thought it was coming from her, or perhaps from Berry. But something was off about it. It didn't sound organic, and it didn't quite sound like it belonged to her overstressed home objecting to the burdens being placed on it.

As Cheerilee realized, through process of elimination, exactly what the source of the noise was, and exactly what that entailed, the dam burst on her second orgasm, taking the condom with it.

Twilight Sparkle was not impressed.

Cum-proofing all of Ponyville was, in and of itself, not as daunting a task as it could have been. The place was already quite thoroughly magically waterproofed – a prudent move, considering the town's reputation for attracting disaster. All Twilight had to do was touch up some spells here, reinforce the structural integrity of an old building there, subtly encourage any families with foals below the age of fifteen to go on a day-trip to Whinnyland and generally prepare for the worst. It wasn't that different from what she would have been doing today anyway.

But, dammit, it was the principle of the thing. Here she was, first thing in the morning on a Saturday in July, canvassing Ponyville in order to prepare for an apocalyptic cumshot of all things. She would have outright refused to allow it to get this far if she could help it. She had initially made it very clear to Berry Punch in no uncertain terms that no, she was not in any way allowed to facilitate an orgasm copious enough to submerge the greater Ponyville area.

But then Cadance had gotten wind of it and was enthusiastic to see it through to the end because of course she was. Even putting aside that it was nigh-impossible to get Cadance to abandon a terrible idea once she'd gotten it in her head, she technically had seniority. Twilight could have still put her hoof down, but ultimately the ensuing paperwork would have been much more of a nightmare than just gritting her teeth and trying to minimize the damage.

She still reserved the right to be grumpy about it, though.

The ground shook, like an earthquake. It had been for almost a full hour now, but the intensity had jumped in the past few minutes. There was an audible rumbling, too, that had not been present earlier. Twilight frowned and picked up the pace. She was almost done, but almost wasn't good enough. If even one single building got even slightly damaged by Berry's shenanigans, Twilight was the one who was going to get in trouble. And besides that, she was not enthused by the potential disastrous consequences that might ensue. Her mind was awash with images of ruined books, broken windows, or foals' having to sleep in rooms that stank of semen. No, she had to finish before Berry finished.

She was, thankfully, almost done. She had taken the most efficient route she could come up with, considering that she had to do this solo because of course Cadance didn't give a shit about the consequences of the lewd shenanigans that she had facilitated. Starting from the town square, she had moved outwards in as much of a circle as she could manage given Ponyville's nightmarish road layout, finishing with Sweet Apple Acres and the handful of scattered cottages that dotted the outskirts of town. Of course, she'd spent an extra few hours to make sure that the Library was extra protected, because she had priorities, dammit. Sweet Apple Acres had also taken several hours by virtue of its sheer size, and she'd given extra attention to Carousel Boutique, Sugarcube Corner, and Fluttershy's cottage. Not just because they belonged to her friends, mind, but because each one was almost as important to Ponyville as the Library was.

The extra attention she had given to her friends' homes had, of course, slowed the process down significantly, but thankfully she was almost finished. Just one more cottage to deal with and she could go home and attempt to sleep through the worst of it. She approached Cheerilee's home in a slight rush. There was no need to exhaust herself, after all. She had plenty of time to quickly make sure that Cheerilee's cottage was adequately cum-proofed and then head back home for a big breakfast and a long nap.

Twilight gingerly knocked on the door. Already she could tell that the cottage would probably be fine. Even if she was too thorough a pony to just leave without making absolutely certain, her mind had already wandered back to the library.

Which is why it took her as long as it did to register that nopony was answering the door. Or that the ominous rumbling and groaning had gotten a lot louder as she approached Cheerilee's home. Or that the air absolutely reeked of cum. Or that the whole building was buckled slightly in the middle, quivering and groaning like it was about to burst.

“Ah, fuck,” was all that Twilight had time to say before the cottage unceremoniously exploded.

Most ponies were surprised to learn that Rainbow Dash was something of a morning pony. It seemed uncharacteristic of someone who spent so much time asleep, after all. As she put it, she preferred to get as much work and exercise out of the way first thing in the morning so she could have the rest of the day to spend on whatever she damn well pleased. Today was a weekend, so she had allowed herself a little bit of extra time in bed before getting to her morning routine. After brushing her teeth, she downed a quick breakfast and a cup of coffee before putting on a sweatsuit and heading out to greet the morning.

The instant she opened the door she was greeted by some kind of sticky white fluid smacking her in the face. She coughed, gagging on the musky aroma as she frantically wiped it off, and then looked out at Ponyville. Or what she could see of Ponyville, at least. Most of it was coated in a thick layer of the same off-white stuff that'd smacked her in the face. The air reeked of sex, and in the distance she could see a geyser of the stuff rocketing into the sky.

She stared blankly for a few moments, before sighing. “Nnnnnnnnope,” she said succinctly, before turning around, slamming her door behind her, and going right the fuck back to bed.

The mess wasn’t quite as bad as it could have been, Celestia supposed. Canterlot was close enough to Ponyville that it had taken a good portion of things, but it was high up enough that there was at least not any flooding.

Still, that was hardly any comfort to her as she stared glumly at what had once been a cup of freshly brewed coffee but was now a cup of freshly brewed cum.

“Sorry.”

“You realize,” Celestia replied, her cold and calm tone of voice sending shivers down Cadance’s spine. She paused to take a deep breath, and then slowly let it out. “That you are going to have to clean this all up.”

Cadance nodded slowly. “Well, yes, it’s only fair.”

“All of it.”

“Well, of course.”

“Alone.”

“... Yes’m.” There was no point arguing, Cadance supposed. It was a fair enough punishment, though she maintained that Berry Punch should shoulder at least some of the blame. But it wasn’t really her place to decide who gets punished how much. “I’ll also bake you some replacement cupcakes.”

“I’m expecting a whole multi-tier cake. Actually, make that three, and then I might consider not disowning you.”

“Fair enough.”

Cheerilee moaned. It was hardly the first of the day, but this was a moan of exhaustion rather than arousal. She blinked her eyes, staring blearily out at the blurry environment, too tired to focus her vision. “Wha..?” She felt sticky and hot and crusty all over, and the air was saturated with the stench of sex. “Berry? What time is it?”

“Dunno, didn't think to bring a watch,” Berry muttered from somewhere in front of Cheerilee. “Sun looks like it's mid-afternoon-ish, though.”

“Oh.” It was all she managed to get out before she was interrupted by another orgasm. Things had been dying down, with more and more time between progressively less copious climaxes, but that hardly actually mattered when one considered just how long she'd been going and how productive she'd been. “Do you have any idea how long this'll keep up for?”

“I figure we've got another few hours at least. Probably shoulda given you a few less of those pills, I'm thinkin'.”

“You think?”

“Yeah, yeah, I know.” Berry was sprawled lazily across Cheerilee's balls, completely and utterly spent. “In case you forgot, I've got a history of not thinking things through.”

Cheerilee sighed wearily. “Well, at least it's gonna stop at all eventually, right? I hope?” She paused to cum again. “Hey, uh, so, speaking of which, this is all gonna go away after a while, right?”

“Um.”

There were several minutes of dead silence. “Berry.”

“I'm pretty sure that your production'll go down to just slightly above mine in a few days.”

“Berry.”

“Don't worry about your house by the way, part of the reason it took so long to save up for this is I wanted to make sure you were very generously insured for Act of Cock.”

“Berry I work with children please tell me this six foot penis isn't permanent.”

“It, uh, might be a little permanent?”

“Berry.”

“Don't worry! I invested in a whole bunch 'a cock-concealing clothing. Your normal life will be entirely uninterrupted and now you get a whole six feet 'a meat to play with whenever you want!”

Cheerilee sighed wearily, which briefly transitioned into another groan as she came again. “Ugh. Well, this was kinda fun at least. And it's not like I'm permanently out of a home or anything.”

“Yeah, see? Gotta stay positive, sis!”

“But.” Berry sheepishly squeaked. “You still put me through some pretty major inconveniences based on a weird incesty whim you had and that's not okay.”

“Sorry, sis,” Berry muttered. She sounded genuinely remorseful, at least. Cheerilee sighed. She just couldn't stay mad at her, considering her heart was in the right place in a twisted sorta way.

“It's okay. Just...” she paused for another orgasm. “You owe me, okay?”

“Yeah, I figure that's fair. Tit for tat and all that.”

“Something like that.” Cheerilee couldn't help but smirk wistfully. “I mean, it's not like your cock is the only thing I was jealous of. Just, ah, try to be a bit more reasonable in terms of scale? I'm already gonna have a hard time moving about without magical underwear, after all.”

“Yeah, that's a fair request.”

“Oh, and one more thing?”

“Hm?”

“I'm, uh, gonna need a place to stay for, like, a week.”

Author's Note

This one was originally gonna be a drabble but there's just so fucking much material to work with that I expanded it to being a full fic. The prompt;

"Cheerilee stays over at Berry's place for the night, yet unknown to Cheerilee, Berry has a little something planned for her that involves helping her relax due to her stressful job which involves some special condoms, a bra and a little mischievous idea (Contains: Paizuri, overly filled condoms, futa and a little morning wood),"

as you can prolly tell, i went a wee bit overboard <_<

Enjoy~
