> The Big Date > by MassDriver > -------------------------------------------------------------------------- > Schoolgirl Crush > -------------------------------------------------------------------------- Rainbow Dash sprinted forward, taking long, powerful strides. Approaching the pad, she sprang from the ground, sailed towards the sky, and turned her body in midair. Her body: ideal. Her form: perfect. Final assessment: awesome. Her tight, toned rear end gently grazed the high jump bar as she went over it. The bar wobbled, but didn't fall, and Dash landed flat on the pad with a flumf. “Yes!” Rainbow Dash extended her arms in triumph, even as she lay flat. She hopped off the mat and looked around, ready to bathe in the adulation of onlookers. The track coach was applauding, as were her teammates – even the competitors from other schools were clearly impressed. Even without wings, Rainbow Dash could fly higher than anyone. Well, the love of teammates and rivals was all well and good, but there was one set of eyes she particularly wanted on her. And those eyes were... pointed at the shot put circle. Literally the opposite direction. Oval Office, at the moment of Dash's stunning performance in the high jump, had been watching... Applejack. It made Rainbow Dash feel ridiculous, having a man come between her and one of her closest friends. You'd think that thwarting even one supernatural threat together would have elevated them above petty high school drama. And they'd taken down several, all with the magic of friendship. But now here she was, fuming about how the boy she liked was paying attention to someone else. Even after all she'd been through, Rainbow Dash was only human – aside from the parts of her that became pony-shaped when she played music. It just wasn't fair. Did Applejack even care about boys? Sure, she was friendly with Oval Office, but they weren't dating. They just hung out and talked between classes – and whenever Dash tried to join in, she ended up feeling like a third wheel. It was Applejack's body, wasn't it? Dash didn't want to assume Oval was so shallow, but he was just a guy, and guys cared about looks. And guys didn't necessarily appreciate that a body like Rainbow Dash's, with lean muscle and zero body fat, was flawlessly build for speed and performance... or that some of that performance would translate well to the bedroom. No, they wanted what Applejack had. Big firm tits straining against her t-shirt. A round ass, with a perfect pear shape filling out her gym shorts. Who could blame Oval Office if he looked at Applejack and liked what he saw? Dash stared down ruefully at her A-cups. Through training and willpower, she'd gotten her body to do everything she wanted it to. Her body could jump high, run fast, and kick ass... but the one thing she'd never get it to do was grow. Certainly not in the ways she needed. Training could do a lot, but it wasn't magic. As she headed back to the bleachers to retrieve her water bottle, a thoughtful expression came over Rainbow Dash's face. No, training wasn't magic. But you know what was magic? Magic. Magic was magic. And unlike most people, Rainbow Dash knew where to get some magic. --- “No,” said Sunset Shimmer. “Come onnnn,” whined Rainbow Dash. “There's gotta be a spell for enhancing your body.” “Not for boobs,” said Sunset, avoiding eye contact with Dash as she tuned her guitar in the otherwise-empty club room. “Breasts aren't really a thing in Equestria.” “What about for butts?” asked Dash. “Some ponies must want a little more back there, right?” Sunset's hands paused, and she sighed. “There are cosmetic enhancement spells, yes,” she said. She looked Dash in the eyes, her expression severe. “But I'm concerned about the consequences of using magic out of jealousy, and for personal gain.” “Huh?” Dash stared dumbly for a moment before the realization hit her. “Oh!” she said, “You're worried I'll turn evil like you did.” Sunset Shimmer winced, as if struck. “Yeah, basically,” she said. “This took me a while to understand, so I'll try and explain it to you as best I can. Magic isn't... inherently a force that seduces people to commit evil acts. In Equestria, it's part of daily life. But in this world, it's unheard of. The seven of us are some of the only people on the planet with access to magic, and that's a huge responsibility. We've stopped bad guys in the past, but if we go bad, there's basically no one to stop us.” “Aw, come on,” said Rainbow Dash, rolling her eyes. “I just want to use magic for one selfish thing. Just one, and I'm out of the game.” Sunset scoffed and returned to her tuning. “No, Rainbow.” --- “Hey Twilight!” said Rainbow Dash, kicking open the door to “Twilight's Lab.” The room was actually an unused science lab on the far end of the campus, and had few of the features you'd expect from a functioning school lab. Luckily for Twilight, the work she was doing wasn't “science” in the traditional sense, and didn't require the same equipment. Currently, Twilight's workspace consisted of several colorful crystals, a magnifying glass, and a few pages of scrawled notes. Her head jerked upwards as Dash entered the room. “Oh hey, Rainbow Dash!” she exclaimed. “What can I do for you?” “Actually,” said Dash, doing her best to sound sincere, “It's Sunset who needs a favor. She's trying out an experiment in... maximizing the performance of the body. Trying to get us in fighting shape for the next time we have to fight something.” “I suppose we probably will,” said Twilight. “That's not a bad idea. What exactly does she need from me?” Dash set her backpack on an empty table, unzipped it, and removed the battered old book she had borrowed from Sunset's backpack. Without asking Sunset's permission. While Sunset wasn't looking. She'd stuck three blue sticky notes into certain pages, and she flipped the book open to the first one. “She wants you to combine this spell-” flip, flip, “this spell,” flip, flip, “and this one.” “Hm,” muttered Twilight. “The two strength-enhancing spells make sense, but why the cosmetic one?” “Uh, well, I didn't totally understand Sunset's explanation,” said Rainbow Dash, “But I think she's worried that the strength spells would have some negative effects on the subject's appearance. She said the spell might need some tweaking to work on a human body – so, uh, make sure it affects the, you know, bustline-” Dash emphasized her words by miming the shape of enormous breasts over her own modest ones, “-and she said to, uh, just go ahead and pump up the power on that spell, just to make sure it works. Like, don't be afraid to go a little overboard.” “Okay, okay,” said Twilight, already withdrawing from the here-and-now as her mind tinkered with the problem. “I can try and have that for her tomorrow.” “Actually, you can just give it to me,” said Dash hastily. “I'm gonna be the test subject, so don't mess it up!” --- That night, Rainbow Dash was bouncing with energy, imagining the body she'd have tomorrow. She pictured her breasts swelling, growing heavier on her chest, so vividly that she could almost feel it happening. She imagined herself bending over in front of Oval Office, showing off the shape of her thick, round ass. “Accidentally” bumping into him, smushing his face into the deep blue canyon of her cleavage. For some reason, she was imagining herself taller in this fantasy, but something about it felt right. Lying in bed, she plunged her hand under her skirt, stroking herself as she imagined looking down at Applejack – not in scorn, but in superiority. Maybe a little teasing – maybe leaning down to shove her tits in Applejack's face. Maybe lifting Oval off the ground, pulling him into her pillowy bosom, and smothering him in kisses while Applejack watched helplessly. Maybe Rainbow Dash would see Applejack sitting in a chair and set her massive, thick ass down right on top of her, feeling the farmpony's tiny body struggle underneath her while she grabbed Oval Office in one hand and slid him in between her tits. She would press her breasts together, embracing Oval in warm, soft flesh - Before Rainbow Dash could question why she was imagining herself bigger and bigger, she came, gushing femcum over her naughty hand. Panting, red-faced, she rolled off the bed to go wash up. --- The next morning, Twilight was waiting by the statue whose base served as the (currently inactive) portal to Equestria. She was taking occasional, hesitant sips from a small coffee, which signified a late night of research. Twilight didn't actually seem to enjoy coffee, but after an all-nighter combining unfamiliar magics, she needed all the caffeine she could get. Twilight saw Rainbow Dash approach and pulled a purple squeeze-bottle from her backpack. “Catch,” she said, but she lacked the energy to actually toss it to Dash, and simply held it in her outstretched hand until the other girl took it from her. “Sweet,” said Rainbow Dash, holding the plastic bottle up to the sunlight. “This is it?” “Uh-huh,” said Twilight. “All three spells diffused into a liquid. I guess you'd call it a magic potion.” Twilight let out a small, sleepy laugh, amused by the strange places her scientific inquiry had taken her. “Oh, but be careful about-” Rainbow Dash held up a hand to silence Twilight, then unscrewed the cap of the squeeze bottle and quaffed the entire potion in one deep, chugging gulp. “Aaahh,” she said, wiping fluid from her grinning mouth. “So what were you about to say? Be careful not to drink it all at once?” A tingle ran through her pussy as she imagined the consequences of an “accidental overdose.” A titanic body, with tits too big for any shirt and an ass that could crush cars... “No, you're fine,” said Twilight flatly. “The bottle was one dose. I was just going to say that the squeeze-bottle's stream is a little wonky, but you sidestepped that little design flaw.” “Ah, okay,” said Dash, feeling a little let down. “So how soon should it start working?” She pulled the front of her t-shirt away from her body, not seeing any growth in her chest. Twilight shrugged. “Beats me," she said. "Let me know when you start to see effects." --- All throughout first period, Dash was subtly rubbing her arms against her chest, trying to feel for growth. Her mood turned sour as her breasts failed to make any forward progress. Maybe Twilight had messed something up – she was a newcomer to spellcasting, after all, unlike her Equestrian counterpart. Maybe it was Rainbow Dash's fault – after borrowing Sunset's book of magic, she'd done her best to identify the cosmetic enhancement spell that seemed to best suit her needs. The other two spells, which enhanced strength, were mostly just to throw Twilight off of RD's true intentions, and maybe gain a little competitive edge in the process. But maybe the spells wouldn't work well together? Could spells just cancel each other out? By the end of her first class, Dash was sure that the potion hadn't worked – but as she stood up from her desk, warmth flooded her body, coursing through her bloodstream and washing over her ass and her tits as waves of intense pleasure. She staggered to the nearby ladies' room, hoping that nobody was paying too much attention. An outside observer might assume she was in the middle of an extended orgasm – and they wouldn't have been far off. Her panties dampened with pussy juice as she stumbled into the bathroom stall – but more importantly, they were growing tighter. And so was her bra. Her A-cup brassiere had been little more than a formality, holding in tits that weren't big enough to jiggle – but the garment was quickly becoming inadequate, with tit-flesh squeezing out the top. “Yes, yes, yes!” she whispered, fairly sure that the bathroom was empty aside from her. She hung her backpack on the stall door, stripped down, and replaced her old undergarments with new, larger ones she'd bought the night before. She hadn't been sure how big she'd get, so she had bought practically every size between herself and a D-cup. Her growth seemed to be slowing, so she picked out a bra and panties that gave her a little room to grow. Before she left the bathroom, Dash took a moment to assess her assets. Her tits had gone from teeny little bumps to fat, firm handfuls. She finally had an ass that stuck out, round and thick. And she felt stronger – not too surprising, given that two-thirds of the potion had been strength-enhancment, but it was a nice bonus. She was almost as excited to try out her new strength as she was to try out the attracting power of her new T&A. By the time Dash took her seat at her second-period history course, her growth had nearly stopped – but the coursing warmth in her tits and her ass was still there, and it had spread to her pussy, leaving her poised at the edge of climax. Sometime soon – very soon – Rainbow Dash was going to have to cum. And it only made things worse that this history class was one of the few she shared with Oval Office. Oval was ahead of her in most subjects, taking advanced placement classes where Dash just took the basic requirements. But they'd both taken this class out of genuine interest in the subject matter, and on good days, Rainbow Dash got to sit next to Oval Office. Today was a very good day, and Dash got a seat in the middle row, right next to cute little Oval, with his adorable little glasses and that cute soul patch... It felt strange that the words “cute” and “little” were coming to mind. She definitely still found him sexy – at this moment she desperately wanted to pull him up from his desk, tear his pants off, and fuck him right in the classroom – but he also seemed... smaller? Rainbow Dash blinked and straightened her back, scanning the classroom. It was hard to be sure, but it really seemed like she had grown. Not just in her bust and her ass, but in height. Maybe two or three inches, but even that would be enough to make her slightly taller than Oval. Just the thought of it made her pussy throb, and her panties darkened as moisture continued to flow. She hadn't considered the thought of getting big all over until her jill-off session last night, but something about it was just so fucking sexy. If she were bigger than Oval and bigger than Applejack, there would be nothing to stand in the way of love. During a lull in the lecture, Oval turned to look at Dash, and their eyes met – but the young man couldn't stop his eyes from wandering over the newly enlarged, newly magnificent body of Rainbow Dash. RD smiled; if she didn't already know that her body was captivating, this was the proof she needed. She was impossible to ignore now, big in all the right places, bigger than Applejack. Dash smiled as she imagined Oval's cock growing uncontrollably hard in his pants, and a shift of his legs seemed to confirm her suspicions. For the rest of the class, Dash faced forward, pretending not to notice Oval Office's eyes on her. She arched her back occasionally, pushing her tits forward and moaning softly. Other boys turned to look at her – and a few girls – but she didn't pay them much mind. She wanted Oval. If she got attention from anyone else... that was fine. Class couldn't end soon enough. Her pussy was keeping itself nice and wet, hungering for dick, and she squirmed in her seat, trying to keep her needy love tunnel satisfied. When the bell rang, she sprang from her seat and advanced on Oval, backing him up against the wall. “Hey, Oval,” she said, doing her best to loom over him, “Were you staring at me all class?” She put her tits so close to his face that her nipples almost brushed his chin. She must have been even taller now than at the start of class – maybe six three at this point. “No way,” said Oval, a blush turning his blue cheeks purple. “I... I thought you looked at me at the start of class, and I looked back at you... that's probably what you noticed.” “Aw, that's too bad,” said Rainbow Dash. “Because I went through a little bit of a growth spurt recently, and I was starting to worry that no one noticed.” That was an outright lie, of course; plenty of eyes had been on her since she'd grown. “And I was thinking that if a handsome guy like yourself did notice, maybe he should be the first one to take my bodacious new body on a date.” “You're... asking me out?” “Hell yeah!” said Dash. “I mean, you're not with anyone, right?” She leaned in conspiratorially. “And even if you are, it's not like she has to know, right?” “No!” said Oval Office. “I mean, no, I'm not with anyone, and, uh, yes, I'd love to go on a date with you.” “Awesome!” said Dash. “So where are we going?” “Uh...” Oval cast his gaze down nervously. “Well, dinner and a movie, I guess? Why don't I pick you up at, uh... six?” “Six,” repeated Dash. “Sounds great, Oval. See you then.” She reached out a finger and traced it from the neckline of Oval's shirt down to his belly button, feeling the young man tremble as her finger neared his crotch. Dash wanted to drag her fingers deeper, reach her hand down the front of his pants right here in the classroom and take hold of that stiff blue cock. She felt so powerful now, almost unstoppable – if she wanted to jerk a guy off right here, who would stand in her way? But she held herself back. Being a young woman of six feet and three inches was pretty special, but it didn't make her unstoppable – she'd still catch hell for giving Oval Office a handjob during school hours. She did, however, give Oval Office a slap on the ass as she sent him on his way, making him jump. And with him gone, there was nothing for Rainbow Dash to focus on but the heat in her own pussy. Her womanhood was pulsing with primal need, caring nothing for “dinner and a movie.” It demanded sex, rough and sweaty and breathless. Usually, she was able to push down those desires long enough to get home from school, but she wasn't used to desire this powerful. Her body was getting stronger, but her self-control wasn't. Panting, she ran for the locker room, blowing past startled students as she charged down the halls at almost superhuman speed. The bell for the next class rang, and Dash slowed as she pushed past a gaggle of girls exiting the locker room. Good – the room should be empty now that the next period had started, giving her a nice empty space to jill off in. At least it was empty in theory – because when Rainbow Dash threw open the door, she came face to face with Applejack, who was idly tapping at her phone, dressed half in her gym uniform and half in her usual shirt and skirt. “Applejack?” said Rainbow Dash. “What're you doing here?” “Hey there, Dash,” said Applejack, barely looking up from her phone. “I got this period free, so I'm just takin' my time here.” Shit. Dash needed Applejack gone now. She was the worst person to find here in the locker room. Applejack was tall and shapely, and she got all of Oval Office's attention... just seeing her was reminder of all the things that Dash didn't have. But wait. Dash was tall and shapely now. Dash was going on a date with Oval Office. Rainbow Dash had everything she wanted, everything she'd envied Applejack for. There was no reason to be intimidated by her anymore. “Okay,” said Rainbow Dash, leaning down to accentuate the size of her tits and twisting her body to reveal the curve of her ass. “Well, just so you know, I'm gonna head on back to the showers and masturbate. I just scored a date with Oval Office, and I gotta work off some of that excitement, you know?” Applejack's head jerked upwards. She hadn't really been looking at Dash before, but now she saw her – tall, curvaceous, beaming with pride. AJ's mind was overloaded with baffling new information – Dash was dating Oval, Dash was going to masturbate in the locker room, Dash was taller than her now – so her mouth did what it usually did when her brain gave it nothing meaningful to say. “What in tarnation?” “So yeah,” said Dash, slowly turning her body to further show off her new curves. “Feel free to stick around, but I'm gonna be making some noise.” “Dash,” said Applejack, finally finding her voice, “Are you bigger?” Rainbow Dash flipped her hair casually. “Oh hey, you noticed,” she said. “Yeah, had a bit of a growth spurt.” Applejack narrowed her eyes. “Ya'll're eighteen, Dash.” “Yeah, I know, right?” said Dash. “Little late in the game for my development to get a second wind, but I'm not complaining.” She lifted her tits with both hands and pressed them together. “And I bet Oval Office won't be complaining either.” Dash noticed that her boobs felt bigger now, and her bra was growing tight. Applejack's mouth tightened, holding back fierce words. “Dash,” she said, layering a calm tone over the frustration evident in her face, “A year ago, I might've just shook my head and let this 'growth spurt' story pass. But I know as well as you do that there's such a thing as magic, an' it can change yer body.” “You accusing me of something?” asked Dash, staring down her nose at Applejack. “Just one question and I'll be on my way,” said Applejack. “Ya'll didn't put some kinda love spell on Oval Office, did ya? 'Cause what you do with yer body is yer own business, but puttin' a spell on someone else is crossin' a line.” Dash laughed. “You think I need a love spell to get a guy? With a body like this?” Applejack continued to stare daggers at Dash, and Dash rolled her eyes. “Ugh, fine. No, I didn't use a spell on Oval Office. Why do you care? You got a crush on him?” Applejack just grunted, gathered her things, and stomped out of the locker room. Dash chuckled as she passed; Applejack was honest to a fault, and when she stayed silent rather than answer a question, it spoke volumes. Rainbow Dash hadn't been sure that Applejack had a thing for Oval, but now she knew. A pang of guilt throbbed once in her chest. But her pussy, wet and hot as ever, was stronger than her conscience. Dash stripped herself down, throwing her clothes onto benches as she made her way to the shower. She stopped once she was down to her underthings, admiring her nearly-naked body and the way it strained against the pink bra and panties she'd changed into. The bra had been spacious when she'd put it on in the bathroom, but now it was almost overfull, and her tits burst forth when she unclasped it. Her panties were practically dripping with pussy juice when she peeled them off and set them on the benches outside the shower room. Dash gasped as she sank her hand between her wet lips. Her body had been tormenting her, crying out to be touched, and now it was rewarding her with intense waves of pleasure. She stepped into the showers, and her free hand turned on the hot water. She sighed, relaxing her body as the water ran over her back, and began to work her hand into her pussy. Her cunny didn't need much from her - she was already so close to climax, just from teasing Oval and Applejack over the past hour. She ran her fingers around her pussy lips, she rubbed at her clit, and her mind filled once again with thoughts of being bigger. She pictured herself peeling away the roof of the school and tearing the clothes off a doll-sized Oval Office, then thrusting him into her cunt. She pushed her fingers deep inside herself, imagining that they were the body of her crush. In her fantasy, the little guy filled her pussy, his tiny legs kicking as he went in and out of her. She imagined herself looking down at a tiny Applejack, who fumed with jealousy as Rainbow Dash pleasured herself with the boy whose heart she'd won. Climax hit hard, bringing Rainbow Dash to her knees. Her body rocked as her cunt sent waves of sensation rolling through her, and her orgasmic cries echoed off the shower walls. Water pounded at her back as the climax ran its course, soaking her hair and running between the thick cheeks of her ass. Her body tensed and untensed with each throb, and she could swear she felt herself growing again, her breasts and her buttocks inching outward as her quivering body knelt on the wet white tile. Through panting breaths, she rode out the rest of her orgasm. For a moment, she was in awe - her climax had been so intense that she felt like it would leave her fatigued for days, but her strength returned and she brought herself shakily to her feet - And swore loudly as the crown of her head hit the metal showerhead. She stumbled away and looked back at where she had been standing, assessing the showerhead's height. It was set high up in the wall, high enough to easily clear the head of any girl who stood under it - and that meant that Dash really had grown during her most recent orgasm. Her body, still coming down off her climax, now buzzed with excitement at the thought of it. How tall was she now? Six five? Six six? She felt stronger, too - she felt like she could tear the locker room's benches off the bolts that held them to the floor, but she restrained herself. This growth was going to be hard enough to explain without causing rampant destruction on top of it. After drying off, Rainbow Dash grabbed a larger set of bra and panties out of her backpack and affixed them onto her bigger, better body. This day was already awesome, and she hadn't even gotten to her date yet. --- Oval Office's heart was pounding as he waited in his car. He stared down at his phone, rereading the string of heart emojis that had been Rainbow Dash's response to his "I'm here" text. How had this happened? Rainbow Dash had always been the athletic, self-assured girl he'd admired from afar. Before today, he wasn't even sure she knew who he was, and he'd never had the confidence to approach her. He'd more or less given up on getting to know her, and had turned his attention to Applejack - who was just as cool, albeit in a more humble and downhome sort of way, and much more approachable. He'd thought that his friendship with Applejack was maybe going somewhere, and he was close to asking her out - but then Rainbow Dash had come out of nowhere, suddenly tall and curvy, and asked him on a date. As he looked up from his phone, he saw Rainbow Dash ducking under the frame of her front door. Was she taller now? This had to be magic, right? Oval Office didn't know anything about magic - except that it was real and it sometimes made people into demons or ponies. And if there was a better explanation for a girl going through two growth spurts over the course of one day, Oval couldn't think of one. And if magic looked like this - a tall, beautiful girl with D-cups and a thick bubble butt on a tight, athletic body - then magic was all right by him. Dash usually favored skirts, like the rest of her friend group, but today she was wearing butt-hugging jeans and a tight pink shirt, to better show off her assets. As he watched, Dash opened the passenger side door and clambered inside, contorting herself slightly to fit her body into the car. "You look beautiful," said Oval Office. "And if you need to adjust the seat, you, uh..." "Yeah, I got it," said Dash, rolling the seat back to accommodate her height. Her tits bounced as her body jerked back, and Oval did his best not to stare. They were bigger than he remembered, fat and round, each one almost as big as his head. "Thanks. You look really handsome." Oval Office chuckled nervously. “Thanks,” he said. “I was worried a shirt and tie would be overdoing it, but...” In fact, he did look a little overdressed next to Rainbow Dash, but onlookers were much more likely to notice the height disparity between them. “Nah, you look great!” said Dash. “So where are we going? I'm pretty hungry, I gotta be honest.” Oval started the car. “Well, I was thinking of trying that sushi place across town,” he said, “But if you're really hungry, we could just hit up that diner near campus.” “Hell yeah,” said Dash. “I need to refuel after that growth spurt, and a little sushi platter isn't gonna do the trick.” “Refuel for what?” asked Oval. “You planning another growth spurt?” “Mmmm,” moaned Dash, as a devious smile crept across her face. Her hand squeezed Oval Office's thigh, and his body tensed nervously. “You'd like that, huh? Just how big do you want me? You wanna walk arm-in-arm with a ten foot girl, boobs bigger than your head?” Oval shifted in his seat, trying to keep his boner from becoming obvious. Dash's hand crept closer to the intersection of his legs, and he shuddered with anticipation. “Or maybe bigger?” she said, teasing his inner thigh with long, sky-blue fingers. “Maybe you'd like some fifty-foot-woman action?” Oval Office took a moment to choose his words. In fact, seeing a woman grow bigger and bigger had been one of his fetishes for a long time. But even when he was faced with a girl who was growing, almost before his eyes, it seemed dangerous to admit it. “Well, you'd look hot at any size,” he said, “But I wouldn't be any good to you if you were that much bigger than me.” “Hm, maybe you could grow along with me, then?” said Dash. She didn't say it, but she was starting to think about how to get some more of that potion from Twilight. Having Oval grow along with her would be pretty hot; they'd become Canterlot High's number one power couple for sure. --- Dash was never all that concerned with being ladylike, but ordering a third burger seemed like it might give Oval Office the wrong impression. Being a big-and-tall girl was cool, but forcing a guy to foot the bill for her growing hunger might be... not so classy? Especially on a first date. So she forced herself to be satisfied with two burgers, promising herself a snack when she got home. Aside from that, though, the date was going awesomely. The diner was a nice, low-pressure venue, where two lovebirds could share a booth and get some decent grub. Oval Office was really easy to talk to, now that she'd broken the ice. He enjoyed listening to her talk about her adventures with the other Rainbooms – which Oval had only ever witnessed from the sidelines – and she liked hearing about his triumphs and losses on the debate team. Dash's sexual appetites had been tided over by her self-love session in the shower, but even now, as she was trying to get to know Oval, she felt them creeping back up. The little guy was just too cute, and she couldn't stop imagining him naked. She wanted to pick him up, carry him into the diner's bathroom, and fuck so hard that the stall doors fell down. But she held herself back. It would be a shame to rush the date's climax, since it was already going so well... “Aw, fer fuck's sake,” muttered a familiar voice, just loud enough to be audible at Dash and Oval's booth. Rainbow Dash turned around to see Applejack standing in the diner's doorway, simmering anger on her face. Dash, feeling even more confident than usual after the success of her date, smiled and waved Applejack over. AJ was still for a moment, weighing her options, and then she walked stiffly over to Dash and Oval's booth. “Hey Oval. Hey Dash.” Her face was deeply red, her mouth a tight line. “Sorry fer swearin' just now.” “Nah, it's okay!” said Rainbow Dash. “I'm sure you had a good reason. Maybe you had a rough day?” AJ was silent. “Anyway,” Dash continued, “I'm here on a date with Oval Office! You two know each other, right?” “Yeah,” said Oval, sensing the tension but unsure how to defuse it. “Nice to see you, AJ.” “Yeah,” said Applejack, her tone softening now that she was speaking to Oval. “So... you an' Rainbow Dash, huh?” “Uh-huh,” said Dash, before Oval could speak. “Oval Office is a guy who knows what he likes, you know? A nice thick ass, and a couple of these...” she turned to Applejack and thrust out her tits, subtly pulling at the bottom of her shirt to make it tighter. As the fabric stretched around the pillowy curves of her breasts, her nipples began to stand out. The largest bra she'd bought for herself had started to become uncomfortably tight while she was getting ready for her date, so she'd left it at home; her breasts, to her delight, were firm and self-supporting despite their size and weight. AJ snorted, averting her eyes from Dash's knockers. “I think Oval deserves a little more credit than that, Dash. Just 'cause he's a guy don't make him shallow.” “Woah, woah, no one said he was shallow,” said Dash, “But back before my little growth spurt, when you were the girl with the best body in class, wasn't he all over you? I think Oval Office knows he's a hell of a catch, so it only makes sense for him to go after whoever's hottest.” Oval Office held up his hands. “Hey, Dash, c'mon-” “But no hard feelings, right?” said Rainbow Dash. “Heck, I'd even invite you to sit with us, but my thick ass is taking up my side of the booth...” she gave her meaty glutes a light slap. “And the other side is reserved for this cutie.” Unseen, Dash slipped her foot out of her sandal and lifted it under the table, finding Oval's crotch with the ball of her foot and massaging it softly. Oval was immediately shocked into silence – aside from the soft gasp he released at RD's gentle touch. “Anyway, AJ, I think you can guess where this date's headed, so if you could give us a little privacy, that'd be awesome. Me and Oval can tell you all about it tomorrow, 'kay?” Applejack was almost shaking now, fists clenched. But she backed down, and without a word she turned and left the diner, somehow managing to angrily ring the bell over the door as she exited. Oval Office leaned back in his seat, struggling to speak as the ball of Dash's foot worked over his stiff dick through the crotch of his pants. “Dash,” he gasped, “That was a little... mean, you know? Aren't you... aren't you friends?” Without slowing the pace of her footjob, Dash casually waved off Oval's comment. “AJ's a tough girl,” she said. “She can take it.” She raised a finger to call over the waitress. “Hey, Oval, I'm not really feelin' the movie. Can we just go back to my place?” “Uh, sure,” said Oval Office, “I can take you back home.” Dash chuckled. “I'm not asking you to take me home, dude,” she said. “I'm saying we should go back to my place.” “Oh,” said Oval. --- “Make yourself at home,” said Rainbow Dash, indicating her bedroom with a sweep of her arm. “Just do whatever you normally do in your own bedroom. You know... hang out, sit on the bed... take your pants off...” She slapped him on the butt, and the force made him stumble into the room. Rainbow Dash's room was a shrine to athleticism and awesomeness - which was to say, it was a shrine to Rainbow Dash. Trophies crowded every horizontal surface, and plaques and pictures lined every vertical one. Dash had enlisted her friends to take action shots of her at various sporting events – track, soccer, basketball – and the best shots were all here, constantly reminding Rainbow Dash of how awesome it was to be her. A less generous soul would have found it a little tacky, but Oval Office was hopelessly enamored already, so he didn't mind being surrounded by Rainbow Dash. Which was good, because once Rainbow Dash closed the door behind them, she wrapped her thick, powerful arms around Oval, smushing her boobs against the back of his head. “Mmm, finally got you in my bedroom,” she whispered, grinding her crotch into the small of his back. “Now I can do whatever I want with you.” Her hands toyed with the waistband of his jeans, flicking playfully at the button that held them closed. Oval Office, once again, found it difficult to speak – or even think – over the intense beat of his own heart. It didn't get any easier when Dash lifted her shirt over her head, exposing her tits, and embraced his head with her bare flesh. “Ooh, feels good to let the girls out,” said Dash. “Having big tits is fucking great, dude. How're you liking them?” Oval still couldn't answer – the warm sky-blue flesh enveloping his head was overwhemling his senses. Dash's boobs were even bigger than they'd looked during dinner – or maybe they'd just grown. They were bigger than his head now, hanging at the perfect height to encase him in soft, fragrant skin. Impatient for an answer, Dash plunged her hand into Oval's pants and took hold of his cock. “Not bad,” dude,” she said, feeling its hardness. “I mean, I'm sure it would have seemed bigger to me back when I was shrimpier, but still – not bad.” She reached down further and gently hefted Oval's balls. “So hey, man,” she said, “I don't mind filling the gaps in the conversation, but I'm gonna need a yes or a no on this one...” Dash paused for a moment, slowly curling her fingers around Oval's shaft. “You wanna fuck?” “Yeah,” said Oval Office. In an instant, he felt Dash's hand withdraw from his pants, and then her hips bumped against him, dislodging him from her cleavage and knocking him face-first onto the bed. With her trademark speed, Dash took his shoes and socks, then reached underneath him, undid his pants, and pulled them- along with his boxers – off his body. When he turned himself over, he saw Rainbow Dash, already fully nude, towering over him. From his perspective, her tits nearly obscured her face – but he could see her eyes, gleaming with desire. Further down her body, past a tummy lined with lean muscle, was her pussy, topped with a tuft of rainbow hair and dripping with juice. At the sight of it, Oval's mouth started to water. “Ooh,” said Rainbow Dash, “You know where you're needed, huh?” She crawled onto the bed, keeping her pussy level with Oval. “I've been wet all night, just thinking about this moment.” She put two fingers to her pussy, then brought them to her open mouth. “Ooh, that's good,” she moaned. “You want a taste?” Oval nodded and backed himself up against the headboard. Dash crawled forward on the bed, brought her face to Oval Office's, and wrapped her lips around his. Her tongue was huge, thick, and strong, pushing his mouth open to fill it with wet, writhing muscle and the taste of her mouth – and just a hint of her pussy's sweet flavor, leftover from the sample she'd given herself. As they kissed, her huge hanging tits enveloped Oval's cock, and he thrust his hips, taking advantage of the impromptu boobjob. The feeling of Oval's dick thrusting between her boobs made Dash laugh, and she drew her head back, breaking off the kiss. She lifted her body, kneeling on the bed, bringing her pussy up to the level of Oval's face. She gripped the headboard and drew her body closer, filling Oval's vision with her womanhood, dripping with juice and filling the air with sweet musk. Oval was intimidated – both from performance anxiety and from the sheer size of the pussy that was closing in on him – but he wanted it. When Dash's vag made contact, Oval face was instantly awash in sweet femcum, his face almost sinking between her glistening lips. He liked at her folds, and she began to moan, grinding her hips against his face and dripping a constant flow of arousal onto his body. His shirt became soaked with it, and every motion of his tongue filled his mouth with her fluids, forcing him to swallow more and more of her juices. The taste of her was sweet and intense, more delicious that Oval imagined a pussy could ever be, and he lapped desperately, drinking up every ounce. And as he drank, a warm tingle spread from his mouth and throat, down to his stomach - and then it crept up his arms and down his legs, across his scalp and into his crotch. Every inch of him was tingling, and then his body felt... tight? He didn't quite know what he was feeling, so he just kept lapping at Rainbow Dash's pussy, burying his face inside of her as her hips rolled against him. Only... his face didn't seem to sink quite so deep into her now. And her vag didn't seem quite so intimidatingly big anymore. He turned his head upwards, flicking at her clit with his tongue, and opened his eyes. Up above him, Dash's tits bounced with the gentle movements of her body, and beyond that he could just barely see her flushed face. But it all seemed smaller than before. And that's when he noticed that his shirt – the one piece of clothing still on his body – felt uncomfortably tight. The shirt had been a slim, comfortable fit when he put it on, but now it was hugging his chest, almost constricting it. Blindly, he pawed at the buttons, trying to free himself – but his shirt tore open on its own, buttons popping free as his chest outgrew it. The sleeves began to split open as well, and Oval lifted his arms to see what was happening. He'd already guessed that he, like Dash, was growing – but what came as a surprise was the muscle that had developed on his arms. His ripping shirt revealed biceps that simply hadn't been there before – he'd always been slim, with very little in the way of fat or muscle, but now his arms looked powerful. He reached a hand down to his chest and found rippling abs under his fingers... and when he reached down to his crotch, his hand discovered an erect shaft that went up, and up, and up. “Dash!” he said, pulling his face back from her pussy, “You gotta see this!” From what he could see, he seemed to be about the same height as Dash – which at this point was about seven feet. Rainbow Dash looked down, somewhat perturbed. “Don't fuckin' stop, dude,” she said. “You were doin' pretty good.” “No, look!” Oval pointed down at himself, and Dash, eyebrow raised, lifted her body and looked him over. After a moment, realization dawned. “Shit, dude!” she said, beaming. “You're bigger!” She ran her fingers along his arm, feeling the muscle. “And buffer! Did my pussy do this?” She backed her body up to get a better look at Oval, and she felt her ass thump against the tip of Oval's cock. “Oh, shiiiit,” she said, a delirious grin spreading across her face as she backed up far enough to get a look at Oval's enlarged dick. When she saw it, her eyes widened in awe, and she clasped both hands around its base. “This dick, dude,” she said, leaning her head closer to its tip. “This fuckin' dick.” She was right to be impressed; Oval's cock was thick as a soda can and a good fifteen inches long, having grown faster than the rest of his body. His cock twitched in Dash's hands as her face came closer, and then her lips surrounded it, making a shudder shoot through Oval's body. Dash licked at Oval's cock like a lollipop, showing the same enthusiasm Oval had for her pussy. Oval's body trembled underneath her, strips of torn shirt falling away as his body – and Dash's – grew larger. His head rose above the bed's headboard, and his feet stretched past the edge of the bed, as Dash's eager tongue teased his tip and her mouth swallowed him deeper. Then she pulled back, giving his tip one final lick as she withdrew. “Okay, dude,” she said, “Mouth stuff is fun, but now that we're the same size, how about we kick things up?” Oval nodded, and Dash crawled on top of him, lifting her ass to hover it over the quivering tip of his cock. Oval was struck, once again, by the size of her ass, even wider than her massive bust; like Oval's dick, it was huge even in comparison to her body. And as Dash got herself into cowgirl position, that fat blue ass lowered itself onto Oval. Her womanhood embraced the bulbous tip of his cock and then slid down the long, thick shaft, dripping femcum down its length, until their hips met. And then Dash began to bounce her hips, slowly at first, then faster, slapping her thick asscheeks against Oval's bare skin with each thrust. Oval gyrated his hips, matching Dash's motions, pushing himself deeper each time she came down. His body shook with ecstasy, so overcome with sensation that he didn't feel himself growing until his feet touched the dresser on the far end of the room. “Dash,” he grunted, “We're still growing, we're getting too big...” “Too big?” mocked Dash. “No such thing as too big, dude.” Oval's knees bent as his legs grew longer, Dash's bedroom no longer big enough to contain his full height. “We're not gonna fit...” he protested. “Doesn't matter,” panted Dash. She brushed a strand of rainbow hair from her face and looked down at him lovingly. “You and I get to be big... and strong... and no walls are gonna stand in our way.” She punctuated her declaration by lifting her body and punching the ceiling, effortlessly creating a wide hole to the attic. Oval Office tried to keep his legs in the increasingly cramped room as Dash began to bounce on his cock again, but an involuntary twitch of his legs made him kick through the wall, busting through to the living room. They were growing fast now. Their bodies took up almost all the space in Dash's bedroom, filling it with hot, humid musk – until Dash made some space by elbowing through the walls and ceilings that her arms could reach. Wood and plaster rained down, bouncing harmlessly off Oval's rigid chest, until Dash had bashed away everything between them and the great outdoors. Oval felt RD's bed collapse under his ass, and his expanding body, still shaking with pleasure, pushed aside more and more of her house. “You like being big?” asked Dash, gritting her teeth as her pussy climbed towards orgasm, throbbing and pulsing around Oval's cock. “You like having a long, thick cock, Oval? You like being strong?” Oval gasped out a few affirmations and nodded his head shakily. “Yeah, you do,” said Dash, “Being big is awesome, isn't it? Your hot body and your fat cock... my big bouncy tits and big thick ass...” She rammed herself down on his shaft, hard and fast. “We are fucking hot.” Dash bounced harder and faster – her ass could have crushed cars, and every thrust made it bigger. Each time she lifted her body, her height let her see further and further across her neighborhood – first over treetops, then over rooftops. Each time her tits bounced upwards, they came down heavier, the dark blue nipples fatter. “I want to feel that big cock cum,” said Dash. “I want that blue battering ram to blow in my pussy. Fill me up with fucking gallons, dude. Can you do that? Can you cum for me?” Oval's quaking body was making the ground shake, cracking asphalt and setting off car alarms as his body outgrew RD's front yard. He felt his balls tighten and his cock twitch, climax rising through his shaft, and then Dash's dirty talk send him over the edge. His load shot like a rocket through his shaft, splattering thick gallons of cum against the back wall of Rainbow Dash's pussy. “Fuck yeah,” grunted Dash, feeling the liquid warmth filling her love tunnel. “So much fuckin' cum-” And then she lost it, her pussy bursting with femcum as it tensed around Oval's shaft. She threw her head back, her body shaking and her tits bouncing as her climax shook the earth. Sweat plastered her rainbow bangs to her face as she moaned her way through her orgasm, bouncing her giant ass on Oval Office's hips. Finally she collapsed, falling forward onto Oval's prone body, her tits squishing against his chest as her body settled onto his. "Fuck, dude," she gasped. "Being big is fucking great." She brought her lips to his and kissed him - just a brief peck this time. "Dude, you got an amazing body now. You know who'd love to see it?" --- The walk to the Apple family's farm would have been time-consuming under normal circumstances, but for a couple of fifty-foot titans, it was just a casual stroll. Oval was trying to follow Dash's example of casual, confident nudity as he followed her through town, but it didn't come quite as naturally to him. He was proud of his newly huge, buff body - and his cock, still long and thick even as it dangled between his legs, was a sight to behold. But he couldn't help but feel a little exposed. Dash was paying little mind to the normal-sized people staring up at her from sidewalks and leaning out of windows, but Oval made occasional eye contact with onlookers, smiling nervously at the gawking tinies. He only managed to relax when their route took them to the outskirts of town, where the population thinned out considerably. For most of their walk through town, Oval had been following behind Dash, partly because she was naturally faster than him and partly because being behind her gave him a chance to walk her minivan-sized ass wobble with each step. But as the tree-lined hills of the Apple farm came into view, he caught up with Dash and walked beside her on the rough country road. "Hey, Dash," he said. "Mm-hmm?" "Are we just going to the Apple farm to rub... this whole situation... in Applejack's face? Because she's cool, and you're cool, and... we should get along. All three of us." "Chill, dude," said Dash, slapping Oval on the back. "Like I said, she can take it. We're just gonna have a little fun with her." They reached the Apple farm, stepping over the little wooden fence that marked off their property and walking carefully though the rows of apple trees. Dash motioned for Oval to keep quiet, and he did his best to oblige - though he was doubtful that they'd be able to sneak up on anyone at their current, ground-shaking size. But it seemed to work. At least, no lights came on, and no Apple family members rushed out of the house, as the two giants approached the Apple home. Without a word, Dash grabbed the base of Oval Office's cock and began to stroke it, slowly working it into hardness. --- Applejack lay flat on her bed, naked, her hand working disinterestedly at her pussy. She had so much tension to work off - so many conflicting feelings tensed up inside her - but she couldn't get herself excited. Every time she tried to imagine herself with Oval Office, there was Rainbow Dash, with her big, curvy body, sweeping him away. It was so frustrating - Rainbow Dash just had to win, whether it was sports or boys - and now she'd stolen away the guy Applejack had been flirting with for weeks. Why couldn't it just be Applejack and Oval Office? Just her and Oval, she thought to herself, flicking her clit with juice-slicked fingers. God, how she wanted that boy's big blue cock- There was a crash over her head, and the ceiling broke apart, battered away by something huge. Applejack covered her face as little pieces of debris bounced off her, and she opened her eyes cautiously as the dust cleared. The head of an enormous cock was poking through the ceiling of her room. As she stared, a fist-sized drop of pre fell from the tip and landed on her pussy, instantly filling her body with shuddering warmth. It occurred to her that the giant penis' skin was the color of Oval Office's, but beyond that, her mind couldn't make sense of the situation. But she didn't have much time to think about it before the rest of her ceiling was torn away by giant fingers, exposing her to the evening air and the two gigantic bodies that were looming over her house. Oval Office was there, fifty feet tall, his body lined with muscle in ways that made AJ's pussy twinge. The giant cock, of course, was his - and wrapped around its base were fingers the color of a clear sky. Rainbow Dash, whose grinning face looked over Oval's shoulder, was apparently the one who had used Oval's cock to bash through her roof. "Hey AJ!" came Dash's booming voice. "Me and Oval are a thing now! We look pretty good together, huh?" "Dash, what the hell-" Applejack had the wind knocked out of her as Rainbow Dash jerked downward on Oval Office's cock, slamming the tip into AJ's body. "Can't hear you, Applejack!" teased Dash. "You're too little! But hey, if you're, you know, jealous or whatever, maybe you can try and make Oval feel good! The two of us could keep you around as a little sex toy, maybe..." Applejack wanted to shout back at Dash, but she had a face full of cock at the moment. Not just her face, actually - the tip of Oval's cock was so wide that it pressed into her whole upper torso, oozing a layer of precum onto her tits. Unable to contain her curiosity, she dabbed at the fluid and took a taste. It was good - strong and sweet and musky - and her fear and jealousy melted away, overcome by the need for more. Up above, Oval was feeling a little taken advantage of. It certainly hadn't been his idea to bust through Applejack's roof with his dick - but he could hardly complain now that AJ was putting her body to work on the tip of his cock, stroking and licking at it passionately. Her limbs and tongue were tiny, but they were plenty strong, and plenty eager, and they sent sexual electricity shooting up and down his shaft, making his body quiver. Dash worked the base of Oval's shaft, pumping with firm strokes. “Ooh, AJ is loving this,” she said. “And I thought I liked big dicks. Lil' Applejack is going crazy on a cock that's ten times her size. What do you think, Oval? I used to be a little threatened by AJ, but I'd be cool with opening up the relationship if I'd only have to share you with a cock-hungry little doll.” “Applejack...” Oval Office grunted, “I'm gonna cum...” Applejack must have heard him, but she didn't let up. Oval felt small hands grasping at the tip of his cock, and Applejack's tiny tongue swiping around the rim of his cockhole. His hips shook, and he struggled to keep his body steady as orgasm started to take hold. “Yeah,” said Rainbow Dash, leaning over his shoulder to whisper into his ear. “Wanna see you cum, Oval. Wanna see you shoot that thick, hot cum all over that teeny tiny little Applejack. Make her sticky with your cream, big boy...” She stuck out her tongue and placed it delicately in his ear, and that, somehow, was what put him over the edge. Cum exploded from his cockhead, shooting down Applejack's throat and glazing her body with jizz. Oval's load just kept coming, and Applejack gulped it down, instantly addicted to the cum of the boy she'd been crushing on. She stroked her cum-splattered body, rubbing her nipples with one hand and plunging the other one back into her pussy, finally finding the heat and passion she'd been missing before two sexy giants burst through her roof. Rainbow Dash released her grip on Oval Office's dick and peered down into Applejack's bedroom. Everything that hadn't been demolished when Dash removed the roof was now coated in fresh jizz, including AJ herself. The farmpony was writhing on the bed, touching herself, her legs kicking in the air, stretching further and further out with each kick... Rainbow Dash groaned. Oh hell, Applejack was growing too. She should have known – if Oval Office could catch growth off of her sexual fluids, it wasn't too surprising that Oval could transmit it to AJ. It was happening quick, too – soon the soles of her feet pressed against the far wall of her room, and her hand moved faster and faster between her legs. Broken moans escaped her lips as her body quivered and shook – and then climax made her body tense and explode into growth, pushing aside the walls of her bedroom and collapsing an entire half of her house. She stood, panting and naked, growing to match Dash and Oval's height. She met Oval's eyes and flung herself at him, almost knocking him off balance at their lips met. She reached around and grabbed his ass, feeling his steely glutes as her tongue pushed its way into his mouth. His cock hardened again, ticking the underside of Applejack's asscrack as it rose, and he leaned into the kiss, forgetting momentarily about the girl he'd come here with. Rainbow Dash reasserted herself by grabbing AJ and Oval by their shoulders and pulling them apart. “Hey now, farm girl,” she said, glaring at Applejack, “Just because you're big doesn't mean you're suddenly, like...” she made a a vague gesture with her hands. “...part of this.” Applejack smiled and reached out an arm to caress Oval's pectorals. “Oh, I think I am, sugarcube. Judgin' by the way Oval kissed me back and got a hard-on, I think he likes havin' me here.” She placed a hand under her left tit and lifted it, testing its weight. Her breasts had grown, bigger than her head and standing firm on her chest – just a bit bigger than Rainbow Dash's. “So what do you say, Oval? Now that we're both big girls, which one do you like?” Oval Office stepped back and looked at the girls. “I like both of you,” he said. “You're both awesome, and I never asked to be fought over, and... isn't your friendship more important to you that dating some guy?” He gave them both a pleading smile. “Like, isn't friendship literally what powers your magic, or something?” he asked. “I'm not totally clear on that, but a few weeks ago I think I overheard Rarity saying something like that. At lunch.” Dash and AJ turned to each other. “He's right,” said Dash. “We have to promise each other that, no matter what happens, nothing's gonna come between us.” “Yeah,” said Applejack. “And now that that's decided,” said Rainbow Dash, a grin spreading across her face, “How about we have one final competition, out in the open, to see who gets big handsome Oval over there?” “Yeah,” said Applejack. “I'm game fer that.” Oval just shrugged. --- “All right,Oval Office,” said Applejack, “There ain't exactly a precise way to do this, so Dash 'n I are just gonna do our best to please ya, and ya'll can pick a winner. Sound good?” “Sure,” said Oval. The squat apartment building buckled slightly under the weight of his ass, but it was a relatively stable place to sit. They'd come to the city for their sexual rampage, since Applejack didn't want to endanger the trees around their farm if they started to grow any bigger. Dash knelt before Oval, pressing her breasts together with her forearms. “Okay,” she said, “I'll start.” Leaning forward, she took Oval's hard blue cock between her plush tits and leaned her face down, slowly extending her tongue to lick at the tip of his dick. “Mmm,” she moaned, starting to move her tits slowly up and down around his shaft. “Your cock is so tasty, Oval...” The pace of her boobjob increased, and she took the protruding tip of Oval's cock into her mouth, caressing it with her lips. By itself, Dash's attention was enough to make Oval gasp helplessly and throw back his head – but Applejack decided to join in, crawling underneath Oval's hanging legs and licking at the underside of his dangling ballsack. She swiped her slick tongue against the sensitive skin, then wrapped her lips around the sack, suckling at his nuts hungrily. Oval's mind and body hadn't been prepared for the simultaneous affection of two girls, and he struggled to hold himself back, trying to keep his body steady and hold back his climax. By now, he could recognize the feeling of becoming larger, and he felt the rooftop of the apartment building crumbling under his ass as his weight increased. The girls, moaning as they took his cock and balls in their mouths, grew right along with him. Finally, the building under his ass collapsed, and the three giants tumbled backwards into the rubble. Laughing, the girls popped their mouths off of Oval and stood up, offering their hands to lift Oval to his feet. “What do you think?” said Rainbow Dash. “Time to switch places?” Applejack nodded and approached Oval Office, locking lips with him and backing him up against a skyscraper. Windows shattered as Oval's body, now some eighty feet tall, crashed into the side of the building. Applejack came at him relentlessly, sucking at his lips and thrusting her tongue into his mouth as she grabbed the base of his cock. Oval steadied himself, knocking aside cars as he shifted his feet on the asphalt below. With both hands, Oval grasped the underside of Applejack's ass, sinking his fingers into the soft flesh of her thick orange booty and lifting her off the ground. He wouldn't have thought himself capable of lifting Applejack; she was tall for a girl, and her hardworking lifestyle had given her arms and legs wrapped in solid muscle. But his growth had made him powerful, and he lifted her ass up to the level of his shoulders and lowered her pussy, bit by bit, onto his spit-soaked shaft. With her womanhood speared on Oval's cock and her body lifted in the air by his powerful arms, Applejack could do little more than moan and roll her her hips. Oval moved her up and down on his cock, hilting himself inside her love tunnel with each motion. Her walls pulsed around him, throbbing in time with the breathless moans coming from Applejack's open mouth. Oval felt the skyscraper he was leaning against shift as he grew taller, his head ascending past story after story of the building behind him. He felt his cock growing longer, lengthening by foot after foot, driving its way deeper into Applejack's pussy as she, too, grew bigger and bigger. AJ's pussy stayed tight around him, her walls pulsing and her body shaking as Oval Office filled her over and over. She grasped at Oval's shoulders, holding tight as she lost control of her body. Her legs kicked, smashing into the building that Oval was leaning against, knocking over rows of cubicles within. Her body seized and her pussy held tight onto Oval's thick blue shaft, the muscles of her womanhood squeezing with enough force to crush cars. As Applejack climaxed, her pussy dripping femcum over Oval's shaft, he felt his shoulders rising over the top of the skyscraper he was leaning against. The building crumbled behind him, no longer able to prop up his weight and the weight of the girl he was holding onto. Growth was coming fast now, almost giving Oval vertigo as his body rose higher and higher. Only moments after his shoulders crested the roof of the skyscraper, he felt his ass overtake the roof as well. For a moment, he tried to rest his butt on the rooftop - but that proved to be the final straw, and the building collapsed entirely. Oval Office struggled to stand, his weight no longer supported, and he fell to his knees, gently setting Applejack down as her orgasm came to an end. For a moment, Rainbow Dash seemed to be nowhere around - but then Oval looked down and saw her, touching herself as she stared up at him. His and AJ's growth, spurred on by their lovemaking, had left RD behind, and she was still under a hundred feet in height - only a bit taller than the length of Oval Office's cock. Once she saw Oval slide himself out of Applejack, she approached him, staring reverently at a cock that was almost as big as herself. Wordlessly, she climbed up his kneeling body, planted her feet on his thighs, and began to lick Applejack's femcum off the shaft of his dick. She wrapped her legs around his cock like a poledancer, licking it up and down, delighting in the taste of her friend's pussy. And soon AJ's sexual fluids triggered another growth spurt. First, she was big enough to get her lips around Oval's tip, and she did, drinking precum from his drooling slit. Then she was big enough to get her tits around his shaft again, and she gave him another boobjob, embracing his slick cock in the soft valley of her cleavage. Then she was half his size, and with fear and excitement in her eyes she positioned her pussy above his cockhead and pushed herself downward. It was too big to fit at first, and she simply ground her pussy against the soft head of his dick, using it to massage her clit and her moist lips. Slowly, the growth of her body allowed her to take more and more of him. Each motion of her hips brought her a few feet lower on a shaft that was over a hundred feet tall and thick as a Redwood. Oval Office himself was still growing - albeit a bit slower than Dash, at the moment - and he lowered himself from a kneeling stance to a prone position, flat on the ground, to make it easier for Dash to ride his cock. And she rode it eagerly, taking it deeper every second, her tongue lolling out and her fat tits shaking as she bucked her hips and bent her knees lower and lower. As he lay flat, his view of the sky was eclipsed by an enormous orange moon. Applejack's ass filled his field of vision and descended upon him, her pussy settling over his face. He extended his tongue to taste Applejack, and as his tongue parted her folds, he began to see why Rainbow Dash had licked Applejack's pussy juice so eagerly from his shaft. She was delicious, altogether different from Rainbow Dash but still strong and intoxicating. With his face totally covered by Applejack's thick hips, Oval Office blindly stretched his growing limbs through the city streets. He felt his hands and feet pushing cars aside, smashing through brick walls as they extended further and further. The femcum filling his mouth and the feeling of Dash riding his cock were both fueling his growth, and before long his fingers bumped against something stronger than the other buildings he'd touched. Solid stone reinforced with cold steel, standing tall. He curled his fingers around it, finding it to be a perfect fit in his palm, and began to wiggle it out of the ground. Its solid foundation offered resistance, even to a titan such as himself, but he soon tore it free from its base. He brought the tower to his head and interposed it between his face and Applejack's pussy. The tip of the stone-and-steel tower was thick and rounded, and its length was ribbed with blunt protrusions - and as Oval slid it into Applejack's slick love tunnel, she gasped and rolled her hips, testing the shape of it with her sensitive walls. She lifted her body, squatting over Oval so as to give him free access to her pussy. Oval's body was quivering as Dash rode his cock faster and harder. He could feel himself geting close to the point of no return, a climactic buzz rising up the length of his cock. He thrust the tower deeper and harder into Applejack, working to bring her to orgasm at the same time as himself. In fact, she reached it quicker. The tower touched every inch of her pussy, gliding over her most sensitive spots with every thrust, and she was powerless to hold herself back. Her pussy pulsed around the tower, sending cracks along its stone length, and femcum rained from her womanhood onto Oval's waiting face. The taste sent another surge of excitement through him, and his hips bucked involuntarily as his balls seized up and cum shot through the length of his shaft, rising dozens of stories high until it burst like a geyser, shooting thick, hot jizz deep into Rainbow Dash. Dash came, her pussy rapturously squeezing and milking Oval's cock, eager to drink up every thick gallon of his liquid love. The giants came together, grunts and groans of orgasm shaking windows for miles around. Applejack's pussy juice flowed in glorious excess, washing away cars and debris. Oval's cum overflowed Rainbow Dash's pussy and poured onto the streets in thick white flows. The marvelous bodies of the three titans relaxed, shaking the ground as they collapsed. Oval turned to Rainbow Dash, smiling with satisfaction. "Dash," he said, "You were amazing. You've been amazing all night. I... I think you're the girl for me." And then all three of them felt the tiniest pinprick, almost imperceptible at their size. But what followed was impossible to ignore - each one began to feel powerfully drowsy, and as they drifted off to sleep, they had the sensation of falling... --- Rainbow Dash awoke to a blinding light in her left eye. "Oh," said Twilight, lowering her little flashlight, "You're awake. How do you feel?" "Uh..." Rainbow Dash assessed herself, feeling the heaviness in her limbs and the fog in her head. "Not awesome?" "No pain, though?" said Twilight, prodding Dash's arms. "Or numbness?" RD couldn't help but notice that Twilight was about the same size as her. As she took in her surroundings, she recognized Twilight's bedroom, and she saw Applejack and Oval Office lying on the purple sheets of her bed. "Naw, I'm okay," she said. "What happened?" Twilight frowned. "You grew into a... a big-boobed giantess, and instead of telling me there was a problem with my formula, you went into the city and caused millions of dollars of property damage." "No, no," said Dash. "I know that part. After that."

Oval was naked in a flash, and he crawled on top of her, meeting his lips briefly with hers. "It's been a weird couple of days, huh?" "Weird is good," said Oval. "At least, when it brings people together..." He slipped himself inside Dash, and his heart swelled as he heard her sigh in bliss.
