The Big Second Date

“Okay, so - just so we’re all in agreement,” said Rainbow Dash, still sitting on Oval Office’s softening cock, “Not my fault, right? And not Oval’s fault?”

“Oh! Yes! Of course!” shouted Rarity. “Our first priority must be to ensure that Rainbow Dash feels no guilt for the destruction of my family’s property!”

“Rarity, I’m really sorry,” said Sunset, pinching the bridge of her nose. “You had nothing to do with this, and you still offered up your lake house…”

“No, no,” sighed Rarity. “We have all stood together throughout our magical misadventures, accepting risks on each others’ behalf. If I’m willing to risk my life fighting evil, risking mere property is comparatively trivial.” She leaned against her car and slid down to the ground. “Plus, it’s insured.”

“Anyway,” said Sunset, “I don’t blame you, Dash. I was pretty sure the cure would work this time.”

“Me too!” said Twilight Sparkle. “Magic is tricky to work with… so much potential, but so finicky…”

“And you’re a natural,” said Sunset. “But this is a world with no magical libraries, and I’m not the most skilled tutor… it’s only natural that we’d make some mistakes.”

“Great! So no one has to feel bad,” said Rainbow Dash. “And that’s awesome, because I feel great. I just fucked my big, sexy boyfriend after a few days of being really fuckin’ horny.” She sighed happily, grasping her giant round tits. “Such a fuckin’ release.”

“So can you fix this?” asked Oval Office. Rainbow Dash lifted herself off of him, and he gasped as his cock slid out of her.

“Honestly?” said Sunset, throwing her arms to her sides. “I’m really, really not sure at this point. The magic swirling around in your body is a mess. We’ve got spells on top of spells, all tangled up. Maybe it’s time to call Twilight.”

“I really wanted to get this right,” sighed Twilight. “But yeah, I think we need to call in the magic princess for this one. Do you have the magic book?”

“Yeah, I usually keep it with me,” said Sunset. “As for you two,” she said, pointing at Dash and Oval, “No more fucking til we figure this out. Obviously. Think you got it out of your system?”

“Sure,” said Rainbow Dash. “I mean, if you told me it was safe to ride Oval’s cock again, I’d definitely be up for it, like, right now. But if it’s not, then I’m good.”

“Well, good,” said Sunset. She opened the trunk of her car and retrieved the magic book she used to communicate with Twilight Sparkle, flipping it open to the first empty page. She put pen to paper and started writing… then frowned.

“Well shit,” she said. “Not only are we in a cell service dead zone, I’m not getting any reception on this thing either.” Sunset closed the book. “We may just be too far from the portal. Urgh, might just have to drive back to Canterlot High… I guess we may as well, since we’ll want to meet Princess Twilight as soon as she leaves the portal.”

“What about us?” asked Oval Office. “Should Rainbow Dash and I just stay here?”

“Yeah, I’ll bring the Twilights back here once we have something figured out,” said Sunset. “Unfortunately there’s no way to stay in touch with you, but as long as you keep a low profile and don’t fuck, I think we’ll be fine. What about you, girls?” She turned to the girls who had come in the other car - Fluttershy, Rarity, Pinkie Pie, and Applejack. “The house is pretty smashed up - again, sorry, Rarity - so are you planning on sticking around?”

“Well, our driver is still asleep in the backseat,” said Rarity, tapping on the windows of Applejack’s car. “After getting no sleep last night, she was apparently so tired that she decided to sleep in her car rather than walk ten yards to the lake house. Not to mention, she somehow managed to sleep through Dash and Oval’s growth.”

“Yeah, and she wasn’t doing a great job staying awake on the drive over,” said Rainbow Dash. “If it were up to me, I’d let her sleep.”

“Well, if you promise to keep your distance from it, I suppose Fluttershy, Pinkie and I can still use what’s left of the house.”

“Just keep an eye on the lovebirds,” said Sunset - and then she and Twilight climbed back into her car, backed down the driveway, and drove off through the trees. The other girls made their way into the house, leaving Rainbow and Oval basically alone.

Oval had been lying flat beneath Rainbow Dash when they’d been fucking, and he’d stayed prone since then, lying with trees flattened beneath his back and the lake’s water lapping at his toned blue bottom. He was surprisingly comfortable there - the rough bark and cool water would have been uncomfortable for a normal person to lie on, but Oval’s five-hundred-foot body was perfectly cozy - especially with Rainbow Dash curling up beside him.

“Is it just me, Oval,” said Rainbow Dash, draping her arm across his chest, “Or was that totally worth it?”

Oval just laughed.

“I mean it, though,” said Rainbow Dash. “I mean, I didn’t want to break Rarity’s house. That sucked. And I didn’t want to disappoint Applejack. But getting big with you just feels so damn good. Part of me hopes Sunset and Twilight and Twilight find a way to fix this, but part of me just wants to grow with you forever…”

Her finger was moving in circles on Oval’s chest, tracing the outlines of his musculature. Just days ago, his body had been nothing special, at least in his own estimation. But the same magic that had made Rainbow Dash into a curvaceous Amazon had made Oval into an adonis, with handsomely proportioned and perfectly toned muscle all along his body. Rainbow Dash had been crushing on him long before he’d become buff, but she certainly didn’t mind having a boyfriend with washboard abs.

“I feel the same way,” said Oval. “I don’t want to disappoint anybody either, but growing with you feels better than anything. I just wish there was a way to keep this, but not… cause trouble for everyone.”

“I kinda like the part where we cause trouble,” whispered Rainbow Dash. “I mean, not hurting anyone, but… like, being big enough to do anything we want and too strong for anyone to stop us? That’s what I want for us, babe. Settling for anything less just feels lame now.”

Her fingers were making their way lower and lower, creeping down past his abs until they nearly touched his long, flaccid cock. “Oval, when we were fucking, we let ourselves fantasize about the lives we really wanted. We thought we were ‘cured’... we thought we weren’t going to grow anymore. But weren’t those fantasies fucking hot? These past few days when we didn’t fuck, didn’t you spend those days obsessed with the idea of growing bigger? I sure fuckin’ did…”

Her fingers finally reached the base of Oval’s cock, and her fingertips stroked up and down its length. Even soft, it was longer than the lake house was tall, and its whole length began to thicken and grow stiff at Dash’s touch.

“Most people don’t get to live out their fantasies, Oval,” said Rainbow Dash. “But we do. I know you want this just as much as I do, baby. Just let me make you big…”

Oval gasped as Rainbow Dash’s fingers wrapped around his shaft and began to stroke - but he didn’t try to squirm out of her grip. “Dash, just a minute ago we were talking to Sunset… promising not to do this again…”

“I don’t remember saying I promised,” said Dash. “And I don’t think you said anything. So why don’t I start by making you big? I’ll make this big beautiful cock cum, and you’ll get huge…”

“Dash, we really shouldn’t… we’ve been through this already…”

“Aw, you’re always the responsible one, aren’t you, Oval?” said Rainbow Dash. Her hand was gliding up and down his cock as it rose higher and higher; it was still slick from their last fuck, making her handjob easy and smooth. “You’re so smart and responsible… that’s why you deserve to be a big, sexy giant. I don’t even mind if you get bigger than me, dude… How about I jerk you off till you’re ten times my size? Then if I cause too much trouble, you can just pick me up and set me on your big fat cock…”

Oval Office could have kept protesting, but there was no point keeping up the pretense. His new, bigger body was immensely strong, but its needs were just as powerful, and Oval’s self-control hadn’t grown along with it. Having his cock stroked filled his body with more pleasure than he’d ever felt as a normal-sized guy. Resisting temptation had been nearly impossible over the last few days, and now that he was even bigger, he had no hope of fighting back against it.

“Ohh, Dashie, I gotta cum,” moaned Oval Office. “Make me bigger…”

“Yeah, that’s the spirit,” said Rainbow Dash. “Now that we’re on the same page, I’m gonna upgrade this handjob to a BJ.”

Rainbow Dash picked herself up and lowered her tits onto Oval Office’s crotch, sliding his cock into her cleavage. Dash’s breasts were bigger than her head, big enough that a cock of average proportions would be totally swallowed up by her cleavage. But Oval Office’s cock was a hundred feet long, big enough that the tip poked out from within. Dash opened her pale blue lips, salivating with desire, and wrapped them around the fat, slick tip.

Oval sucked in a breath as Dash began to lick at his cock. The head of his dick was bigger than his whole body had been ten minutes ago, and there was a whole body’s worth of pleasure concentrated in that bulbous tip.

And Dash’s tongue was attacking the head of his cock, lapping up the taste of her own pussy and Oval’s spilled cum. She moaned in pleasure as she sucked, feeling the heat in her cunt grow rapidly stronger. Being huge was having the same effect on her as it was on Oval; her arousal grew quickly, and it grew far more powerful than would have been possible in her normal-sized body. For a normal Dash, sucking Oval’s cock would be a turn-on… but as a giantess, she found the experience rapturous, so pleasurable that she could have cum just from having his dick in her mouth. If she let her fingers creep down to her slit, she could make herself cum in a matter of seconds… but she wanted to watch Oval grow first.

“Dash,” whispered Oval, “Your tits are so soft… mmph, make me cum, I wanna get bigger…”

Oval’s legs kicked in the lake, raising waves big enough to capsize a boat. He steadied himself against the ground, digging his palms deep into the ground where his body had flattened the trees. He wasn’t screaming or crying out… but at his size even his gasps and groans were loud enough to shake the walls of the lake house.

Rarity had collected the girls in a bedroom with no windows facing the lake, insisting that Rainbow Dash and Oval Office should have their privacy. This was a mannerly decision, but not a very practical one; had they been keeping an eye on the giant lovers, they would have realized they were getting frisky. And although Rarity, Fluttershy, and Pinkie Pie hadn’t witnessed Oval and Dash’s destructive growth firsthand, they had an idea of how serious the situation was.

When the noises from outside became impossible to ignore, the girls ran to the deck behind the house. The sight that confronted them - two five-hundred-foot giants with perfect, beautiful bodies - stopped them in their tracks. For a moment they simply watched Rainbow Dash squeezing her house-sized tits around Oval Office’s towering cock, sucking greedily at the tip.

But when Oval Office groaned and arched his back, they snapped out of their reverie. If he came, he was going to get bigger - and unfortunately, none of the three of them stood much chance of putting a stop to it. But there was someone nearby who might stand a chance...

“Oh dear,” muttered Rarity. “I had hoped to let Applejack sleep longer than this.”

“Mmph, Dash, I’m close…” moaned Oval Office. Dash mumbled in approval and lowered her head, taking his cock deeper in her mouth. With most of his shaft sandwiched between her tits, she wasn’t able to take his cock deep in her mouth, but she was able to give his tip the full attention of her lips and tongue. She swirled her tongue around his tip, lapping up the gallons of pre that pumped up from his slit.

Oval felt his balls tighten - but that wasn’t the only thing his balls were feeling. Little hands were gripping the taut skin, climbing higher… someone was ascending his ballsack. He looked down at his body, trying to see who it was - but all he could see was Rainbow Dash going to town on his cock, her lips wrapped around the tip while her tits swallowed up the shaft. Whatever was happening on his ballsack, he had no way of seeing it.

Meanwhile, Applejack was regretting her decision to climb up this particular feature of Oval’s anatomy. The farmgirl tended to prefer the direct approach, and that had been the reasoning behind her choice: if she wanted to stop him from coming, then his dick and balls seemed like the place to start. Honestly, the head would have been a better choice - if she could reach his ears, she could reason with him - but his balls were about two hundred feet closer to the lake house than his ears.

Now that she was here, though, she wasn’t sure what to do. Punch his balls? Squeeze in between Dash’s tits and try to climb his cock? There was no obvious solution, and - judging by the growing volume of Oval’s moans - very little time to act.

And on top of that, it was pretty demoralizing to be standing on the giant ballsack of the boy she’d been crushing on a few days ago, watching his equally giant girlfriend give him an absolutely colossal blowjob.

Of course, Rainbow Dash had won him fair and square. Applejack had agreed to that. And Applejack was more emotionally mature than most girls her age - but feelings don’t just go away because a mature person made an agreement. She still admired Oval Office - and while climbing his huge blue ballsack wasn’t exactly romantic, it was a reminder of what she’d lost out on when he picked Rainbow Dash.

And seeing them grow again stirred up feelings of jealousy. Of course Applejack felt terrible about her role in the destructive three-way they’d had… but it had also been so fucking hot. Applejack couldn’t help but imagine herself sucking Oval’s eighty-foot-long cock, giving him the orgasm that would make him even bigger…

She felt her panties getting damp as arousal warmed her magically-enhanced body. She’d been imbued with the same magic as Dash and Oval, and while it wasn’t making her grow anymore, it did give her a body that was highly sensitive. Being this close to a giant act of lovemaking was lighting a fire in her cunt that was hard to ignore.

Grumbling, Applejack shoved her way into Rainbow Dash’s cleavage and began to ascend Oval’s cock. Dash’s tits were still holding his shaft tight, enclosing Applejack within suffocating walls of pillowy flesh. It was hot, and wet, and filled with the mingled musk of Dash and Oval. Oval’s cock had recently been balls-deep inside Rainbow Dash’s pussy, and the smell of her was all over him…

There was a lot of dick for Applejack to climb, but her dose of growth had left her with a peak human physique - and soon enough she emerged from the top of Rainbow Dash’s cleavage, into the shadow of her enormous head. Dash was still sucking, her plump blue lips working their way up and down the head of Oval’s massive cock. Her eyes were shut tight, and she’d seemingly taken no notice of Applejack yet; both giants were too absorbed in each other to pay attention to someone of normal size.

Applejack, clinging to Oval’s dick, began to yell out, hoping that her voice would reach Rainbow Dash’s ears over the sound of moaning and sucking. But as she yelled, the shaft she clung to began to throb - and Applejack realized she was too late.

Between school and farm work, Applejack didn’t have tons of time to devote to the rodeo. But she had rode the occasional bucking bronco, and Oval Office’s twitching cock had a lot in common with that experience. She clung to the underside of his shaft, clutching at the cumvein as gallons of spunk began to pump through it… and her grip nearly faltered as the shaft she clung to began to grow.

Oval, meanwhile, was groaning helplessly as his cock pumped and his body grew. He could feel a little body ascending his cock, and he even correctly guessed that it was Applejack. She had been the one intervening in his and Dash’s attempts to get close over the last few days, so she seemed like the most likely to be doing it now.

Applejack’s presence was a reminder that he really shouldn’t be letting himself grow again. But her tiny hands on his eighty-foot cock were both a source of physical stimulation and a reminder of just how big his body was. If anything, she’d made him cum more quickly.

Rainbow Dash felt Oval’s cock throb in her mouth, and the first gush of cum hit her mouth, splashing her tongue with gallons of thick, hot spunk. She squeezed her tits rhythmically, milking his spasming shaft and swallowing up each fresh splatter of jizz.

A sudden naughty whim made Rainbow Dash raise her head and release Oval’s cock from her mouth. Oval’s dick shot a jet of cum straight up… and then it fell back down, landing on top of Dash’s tits.

And it splattered Applejack as well, coating her body a thick glaze of cum. Grumbling, seeking higher ground, Applejack climbed the rest of the way up Oval’s dick, draping her cum-soaked body over the twitching, spongy tip as it grew bigger and rose higher.

“Holy shit,” said Rainbow Dash, finally taking notice of Applejack. “AJ, are you trying to butt in? No hard feelings, babe, but Oval is mine. He’s too big for a girl like you… and I can feel him getting bigger… She squeezed her tits around Oval’s cock, feeling it grow thicker between them. “Can feel that. Oval? You’re growing again. I wanna see my man get really big…”

Oval Office was, by now, familiar with the feeling of growth - but like the feeling of orgasm, there was no way to get totally accustomed to it. It overwhelmed his senses, lighting up every nerve with pleasure. “Yeah,” he gasped, his cock still firing ropes of cum into the air, “I’m gonna grow for you, Dash, I’m gonna get big…”

He felt his legs growing longer, pushing their way past the edge of the lake. His arms spread wider, flattering more trees near the lake’s edge. His big blue body, tall and strong and completely nude, expanded over the landscape, making the earth rumble. And all the while, his cock was still shooting, firing off more and more spunk as his body grew larger.

Applejack, her body still glazed with cum and draped across the head of Oval’s cock, watched cum shoot like a geyser from his slit. His dick was growing taller and wider beneath her; it was big enough that she could have stood up on it, if it had been holding still… and if it wasn’t so high up. His cock was over a hundred feet tall by this point, and Applejack didn’t want to risk falling.

Oval Office still wasn’t used to giant-sized orgasms. They seemed to go on forever, pumping immense volumes of cum from his expanding nuts as his body grew larger - but in time, of course, this one came to and end. The last few weak spurts of cum washed over Applejack, drenching her in a fresh coat of spunk.

“Oh my God,” moaned Oval Office, his chest rising and falling with breaths that shook the ground around him. “Ohhh, Dash, that was great… it feels so good to grow with you.”

“Heh,” chuckled Rainbow Dash. “I wasn’t growing this time… but watching you grow made me horny as hell, dude. This fuckin’ cock of yours, dude, it’s huge. And I’m not the only one who likes a giant cock. Looks like you got a passenger here!” She plucked Applejack from the tip of Oval’s cock and held her where he could see. “Applejack just couldn’t stay away. I’d be jealous if I wasn’t way, way bigger than her.”

“Oh hey, Applejack,” said Oval. “Hey, sorry about getting big again… and about cumming on you, I guess.” He didn’t say so, but it was pretty damn hot to see Applejack, smaller than a mouse, clinging to the tip of his dick.

“Yeah, you got her real sticky,” said Rainbow Dash. “Mmm, I’m not letting that tasty cum go to waste… let me clean you up, AJ.” She lifted Applejack to her open mouth dragged her tongue across the smaller girl’s body, licking Oval Office’s jizz from her soaked clothes. “Oval, you make some tasty spunk… and you make a lot of it. Wanna get bigger?”

“Dangit, Dash!” yelled Applejack in a furious, full-throated bellow. “You gotta stop this! You know this is just gonna end up like before! You feel good about this, Dash? Corruptin’ Oval Office, makin’ him all big an’ destructive?”

“Oh, come on,” scoffed Rainbow Dash. “You think I’m corrupting him? He wants to grow, AJ. Don’t you remember what it feels like? Don’t you remember the feeling of getting bigger and bigger and still wanting more?”

“Yer just gonna end up smashin’ buildings again, an’ you know that ain’t cool, Dash-”

“Are you sure it’s not cool?” said Rainbow Dash, giving Applejack a grin that was very wide. “Because I remember how fun it was to get big in the city, and I think it’s super cool. In fact, once we’re a little bigger I think I might want to hit the town again…” She extended the arm that held Applejack, dangling her over the water. “Thanks for the suggestion, AJ! But Oval and I need some alone time, K?”

She released Applejack, letting her fall into the lake, and turned to Oval Office. “Sorry about that, dude,” she said. “Holy shit, did you ever get big…” She grasped the base of his cock - now so thick that she couldn’t get her fingers all the way around it - and gazed out over his body. “Fuck, you gotta be twice my size,” said Dash. “This is actually fuckin’ great, you know? Having a boyfriend twice my size with a giant dick? But… fuck, I like being bigger than you, too… and being the same size has some obvious fuckin’ advantages too…” She released his dick and crawled onto his body, sprawling herself across his bare chest. “So now that you’re so much bigger and stronger than me… what do you want to do to me?”

Oval looked down at Rainbow Dash, who was using his muscular chest as a very firm mattress. She was about half his size now, as she’d said - which put him at about a thousand feet tall. And having a body so big that his girlfriend could stretch out on his chest was pretty cool… but right now the hottest thing he could imagine would be to see Rainbow Dash grow. “I think I know what I wanna do to you, Dash,” he said.

He picked up Dash with both hands, easily lifting her from his chest, and sat up. “Ooh,” said Dash, kicking her feet as Oval dangled her in midair, “Where are you taking me, big guy?”

He hadn’t planned to take her far, at least not by the standards of a thousand-foot-tall giant. There was a nearby mountain, just a few giant paces away, that looked like it would be comfortable to lean against - so Oval carried Dash to the foot of the mountain and sat his big blue ass down. He felt trees flattening under his butt, crushed to splinters by his weight, but the rough surface beneath was perfectly comfortable thanks to his enlarged body’s thick, durable skin. And the rocky, rocky side of the mountain was likewise comfy as he leaned his back against it; it seemed like a thousand-foot-tall giant could sit wherever he wanted.

He lifted Dash up until her crotch was level with his face. She was so small - not as small as Applejack had been, of course, but it was still strange to see her toned body, her wide curves, and her heavy round tits at an uncannily small proportion. He wanted her big, and he knew there was only one way to make that happen.

Oval brought Dash’s hips to his face, pressing her pussy against his closed lips. Dash, already slick from arousal after sucking Oval’s cock and witnessing his growth, sighed blissfully as Oval made contact with her womanhood. And she shuddered, gasping in surprise, as his tongue poked through his lips - and through her lips - to probe the depths of her cunt.

“Oh, fuck, you're big, dude,” groaned Rainbow Dash, her toned blue legs kicking in midair as Oval’s tongue journeyed deeper within her. A double-sized tongue was something marvelous; it was twice as long, twice as thick… it filled her, opening her folds just as wide as his cock had when they'd been fucking…

And as much as she loved his cock, she had to admit that his tongue had something his dick didn't. It was nimble, rising and falling like a wave within her, seeking out sensitive places deep in her cunt.

“Holy shit, holy shit,” groaned Rainbow Dash, “Fuck, Oval, you’re everywhere, you’re touching everything inside me…” She tensed her body, trying to hold herself back, but there was no way to stop what was coming. Oval had zeroed in on a spot that made her legs twitch, and he was attacking it with flicks of his tongue, stroking her clit with his open lips. She shrieked with pleasure, grabbing Oval Office’s shoulders to steady herself as her body shook.

The building tension in her core was accompanied by the now-familiar feeling of growth: a warm tingle, a pleasurable swelling. And when that tension broke, Dash grew in a burst, shooting up a hundred feet at once. And that was just the first wave; each powerful throb hit her with more and more growth.

Oval’s grip on her started to falter as her weight increased. He was strong - certainly strong enough to lift a girl roughly his own size - but it was hard to hold her in midair as she gained mass out of nowhere. As her height approached a thousand feet, Oval Office sat up and laid her down on the forested ground on front of them - and all the while, he kept his tongue in her pussy, licking and flicking at her throbbing walls.

Rainbow Dash wasn’t keeping careful track of how big she was getting; all she knew was that she was growing and it felt fucking amazing. But she could tell that Oval’s tongue was getting smaller inside her; it no longer filled her pussy, nor reached its back wall. And after another thrumming wave of climax and a surge of growth, his tongue started to feel smaller than normal, as if she were outgrowing him.

And Oval could tell for sure that Rainbow Dash was getting bigger than him. Still eating Dash out, he could see her thighs growing bigger on either side of his head, and he focused his attention on her clit, hoping to extend the length of her climax. The more she came, the more she would grow - and he wanted her to grow a lot.

“Oval,” Dash grunted, her kicking legs making craters in the earth, “You’re making me so fuckin’ big…”

Oval didn’t let up. It was almost cruel, how persistent he was - licking and sucking her clit as it grew bigger under his tongue - but his desire to see his girlfriend grow was making him greedy. He needed Dash to be bigger than ever. Bigger than anything. He clapped his hands onto her expanding ass, feeling the flesh grow beneath his fingers as he ruthlessly ate her out.

“Well, in case it ain’t obvious,” said Applejack, wringing water from her hair on the lake house’s deck, “My mission was a big fuckin’ bust. Ya’ll come up with anything?”

Pinkie Pie understood the seriousness of the situation - really, she did - but she couldn’t resist a setup. “Speaking of big busts-”

“Yes, yes, Pinkie,” said Rarity, waving one hand dismissively. “We did in fact make some progress, Applejack. I imagine it would have gone much quicker with one of our magical experts on board, but we have established… I suppose you’d call it a resonance between our geode stones. We’ve succeeded in sending messages between ourselves, and we were just about to attempt to contact Sunset and Twilight.”

“You pulled that off while I was over there gettin’ my butt kicked?” said Applejack, pulling her geode-stone necklace from inside her shirt. “Mighty impressive, Rares.”

“Well, it was a group effort,” said Rarity, “and I certainly don’t claim to know how it works; the stones seem to respond to intent more than anything else. Now then, if experience is any guide, this will go more smoothly if we all work together…”

The girls all raised their geode stones and - none of them quite sure how to “do magic” - they focused their thoughts on getting a message to Sunset Shimmer. Their stones glowed, and the space between them lit up with a swirl of color…

“Princess Twilight’s through the portal,” said Twilight. Sunset was focused on driving, but out of the corner of her eye she could see letters forming on the pages of the magic book that Twilight had open on her lap. “I’ll have her wait my lab, okay?”

“Yeah, sounds good,” said Sunset. “Maybe she can even start working while we... “ She felt a buzzing vibration on her neck, and paused. “... the hell?”

Keeping one hand on the steering wheel, Sunset lifted the geode that hung around her neck and clasped it in her palm. It reacted to her touch, glowing brightly - and then speaking.

“Hello, Sunset? Twilight?” Rarity’s voice called out. “If you can hear this, please say something, we have urgent news.”

“Oh boy,” muttered Sunset. “Is it at least a familiar problem?”

“Yeah, nothin’ we didn’t see comin’, I guess,” said Applejack’s voice. “The growth ain’t easy to resist, but those two didn’t last long at all. And Dash was talkin’ like she wanted to go wreck up a city again.”

“In retrospect, it was pretty optimistic to think they’d keep their hands off each other for the six hours it would take to pick up Princess Twilight and drive back to the lake house,” said Twilight.

“Well, now that we don’t have six hours,” sighed Sunset, “What do we do?”

“So is this the same thing she did last time?” asked Applejack.

“Yeah!” said Pinkie Pie. “Twilight knows all these hackers and… I guess she has tons of hacker cred? Probably more cred now, since this plan saved tons of people last time…”

“Her friends can trigger an evacuation,” said Rarity. “I don’t think the three of us can stop Dash and Oval from wrecking the nearest city, but we can try to make sure no one gets hurt…”

“I suppose the rest of it is out of our hands,” said Rarity. She turned back to the lake house and its demolished wall. “I suppose the property damage I have suffered is rather trivial compared to what the city will endure…”

Her geode glowed purple - and a glow of the same color clung to the lake house’s broken walls. Rarity squinted in concentration and focused her thoughts through her magic crystal, and watched the wall start to put itself back together.

“You know,” said Rarity, “These stones are more versatile than I realized…”

Even Rainbow Dash’s giant body had its limits. Not even she could cum forever. Oval looked up and saw the state she was in - her flushed face, her rainbow bangs stuck to her forehead with sweat, her eyes rolled back in her head. She was done.

She was also huge. Her orgasm had gone on a hell of a lot longer than Oval’s had, long enough that her thighs overshadowed his prone body. Her breasts were half a mile away, dominating the horizon beyond the expansive landscape that was Rainbow Dash. “Holy shit,” she groaned, her body almost totally motionless, “That was something else, dude.”

“Yeah, I might have gone a little overboard,” said Oval. “I just wanted to see you big, Dash.”

“Yeah, I guess so,” said Dash. “Shit, I can’t see you. Just how big did you make me, dude?” She lifted her head until she could see past her boobs. “Damn, little guy, you really went to town. You like it down there, huh?”

She brought her legs together, closing them around Oval, pinning him between her thick, powerful thighs. Rainbow Dash had always had powerful legs, and her growth had only augmented that - but it had also added a smooth, beautiful layer of softness. Trapped between her thighs, his face just inches from her pussy, Oval struggled playfully against her skin. Her thighs could have crushed buildings easily - and certainly would have, if she’d subjected them to the same force she was currently exerting on Oval Office. Oval, at one-fifth her size, was durable enough that he wasn’t being hurt, but he couldn’t possibly have escaped unless Dash let him.

“Mmm, maybe I should keep you there,” said Dash, shifting her hips around Oval. “Just keep my little guy trapped between my legs so he can eat me out whenever I feel like it… whenever I wanna grow, I can just shout down to you and you can start licking.”

Oval breathed onto Dash’s pussy lips, making her body shiver. “Damn,” said Dash, “I’m already good to go again… You just gave me the biggest orgasm of my life, and I’m already starting to, like, ramp back up.”

Oval took this as an invitation, sinking his face into Rainbow Dash’s big wet pussy - but Dash responded by opening her legs and scooting backwards. “Hang on, Oval,” she said, “I don’t want to get too much bigger unless you’re coming along with me. It’s cool to be bigger than you, but I don’t want to lose you. And I don’t need you to be tiny; everyone else should be tiny. You get to be my big man.”

“Oh yeah?” said Oval. He lifted himself onto her belly and crawled up her body, raising his head to rest his chin on her immense tits. “Do you want me to be big now? Wanna see me grow again?”

“Yeah,” said Dash, “But not quite yet. Gimme a second to appreciate ya before my little man becomes my big man again.”

She lifted one hand and brushed her huge fingers affectionately through Oval’s hair. Oval felt a pleasurable shiver go through his body at her touch, and he sighed happily as he let himself relax. His head settled into her cleavage, sinking gradually lower as she stroked her hand along his back. He could feel Rainbow Dash’s pounding heart through her chest… and as he lay atop her, the beat of her big, powerful heart grew calmer.

Oval Office felt his own body relaxing as he lay on Dash’s chest. Even though his head was between her tits, there was something almost innocent about the moment they were sharing. Oval had spent the past few days being almost uncontrollably horny, struggling to keep himself away from Dash, and it was nice to have a little time to just chill. When he’d had a crush on Rainbow Dash, he hadn’t just imagined their relationship as a whirlwind of sex - he’d imagined moments like this, where they lay together, just feeling the warmth of each others’ bodies, breathing the same air.

Oval opened his eyes and looked out over the landscape. When they’d arrived at the lake house, it had been trees as far as the eye could see… but now there huge swathes of downed trees, crushed flat by Oval and Dash’s bodies. The woods had been forever changed by their lovemaking… and neither of them had even intended any of the destruction. Both of them were so big that the flick of a finger could bring down a dozen trees at once… and they’d been doing a lot more than flicking their fingers.

At his normal size, Oval would have felt guilty about laying waste to this much natural beauty. But his new, bigger body felt desire and excitement far more strongly than guilt - and besides, he and Dash were replacing the natural beauty with landscapes that were far more beautiful. Whether it was his own huge, muscular body or Dash’s towering, godly womanhood, they were better-looking than any lake or mountain. Every forest that was laid flat, every city that was demolished, simply made way for the two of them to become bigger, until continents cracked beneath their intertwined bodies.

Oval crawled forward, over the soft mounds of Dash’s tits, and brought his face to hers. Although Oval was the one who initiated, Dash was instantly the one in control of the kiss; at five times his size, she naturally took command of any interaction. Her tongue penetrated his lips, filling his mouth completely, as her lips engulfed his. Her hands, which moments ago had been softly caressing him, now pulled him closer. One naughty hand squeezed his butt, kneading his glutes - and Dash’s mouth seemed to be on the verge of consuming him as the kiss went on.

She broke the kiss with a wet pop, and looked at Oval with eyes that were just as hungry as her mouth. “Baby,” she said, “You are so fuckin’ hot, at any size. But I think I’m ready to see you get big again.”

She gripped his body with both hands and held him as she rose to her feet. Oval looked down as he rose into the sky, watching Rainbow Dash’s body ascend to its full height of five thousand feet. He could see for miles, from this height - he could see the curve of the mountains, the edges of the forest, the snaking lines of the highways… and the distant city, with its tall, glittering towers.

Rainbow Dash set Oval Office on one shoulder. It was actually a pretty comfortable fit; with a body one-fifth as wide as Dash’s, he had plenty of space to stretch out up there. “God, you’re cute like this,” said Dash. “I’ve got a sexy little boyfriend I can just keep on my shoulder… or between my legs… But I’m ready to see you grow again. I want to see those broad shoulders, that tight ass, and that long cock get really, really fuckin’ big…” she grinned. “And I want to show you off when it happens. I want people to watch your bod get huge, and then I want to show ‘em that that body belongs to me.”

“So we’re heading into the city?” asked Oval.

“Hell yeah,” said Rainbow Dash. “Don’t get me wrong, dude, your love and admiration is awesome. I’m totally feeling it, it nourishes me, all that shit... But I need more than that. I need…” she rubbed her chin thoughtfully. “Well, I always thought I wanted to have millions of fans. But now that I’m the biggest, sexiest chick alive, I’m thinking more like… billions. Of worshippers.”

The thought of Rainbow Dash as a towering goddess sent a surge of arousal through Oval. “I like the sound of that.”

“And hey, you’ll get your fair share too,” said Rainbow Dash. “Handsome guy like you… once you’re a mile tall, there’ll be tons of chicks willing to worship that handsome body and that big, long cock…” She reached a hand up to her shoulder and ran a fingertip over Oval’s crotch. “It’d almost make me jealous… if I weren’t the only woman big enough for a man like you.”

She set off towards the city, her long strides quickly taking her out of the woods and past crisscrossing roads. She paid little attention to where her feet were landing - she left footprints in farmland, then collapsed strips malls and suburbs under her heels, until finally she stood at the edge of the city.

(Had she bothered to look, Rainbow Dash might have noticed that the city seemed oddly bare, as if an evacuation had taken place. But Dash was far more interested in the idea of a city of worshippers than the reality.)

“This is the place, Oval,” said Rainbow Dash, lifting her boyfriend from her shoulders and setting him down on top of a city block. Oval felt low buildings crumble underfoot, kicking up clouds of dust around his ankles. “You ready to get big?”

Oval shot a glance over his shoulder at the city. “I’m already pretty big,” he said. “There’s like one building taller than me… and none that even come close to you.”

“You might be big, Oval,” said Dash, kneeling down to bring her face closer to his, “But I want you bigger, and Rainbow Dash gets what she wants.” She let herself fall forward, landing on the palms of her hands… and began to crawl towards Oval, licking her lips in playful menace. “I want to watch that cock grow, Oval. Wanna see your trouser snake get thicker and longer til it’s the tallest fuckin’ skyscraper in this little town. I wanna feel it grow… inside me…”

Oval backed away from Rainbow Dash - not because he disliked anything he was hearing, but because the predatory way she was prowling towards him seemed to demand it. He would play the part of the frightened prey animal right up until the moment he got caught.

His backpedaling took him over several city blocks, each footfall demolishing a building or two. And what Oval Office didn’t destroy, Rainbow Dash took care of handily. On hands and knees she crawled after him, and her palms left cracked craters of asphalt in their wake, turning everything beneath them into unrecognizable messes of concrete and steel.

Oval, still backing away, finally encountered a building tall and solid enough to make him trip. He fell backwards, his butt caving in a three-story mall - and Dash kept right on coming, her smile growing wider as she closed in on her helpless prey. And Oval was feeling pretty helpless - he was staring at Dash’s fat, dangling tits, mesmerized by the way they wobbled in the deep blue shadow of her body.

Before he knew it, she was on top of him. At the last moment, she pounced - and when she landed, her breasts came down on top of his chest, knocking the wind out of him. “Got you,” she purred. “And I’m hungry for meat.” She lifted her body and placed a fingertip on the head of his stiff cock. “This is a mouthwatering piece of meat, right here… but I’m so hungry, I think I need to make this thing bigger.”

She descended on his cock, engulfing his entire crotch in her open mouth. She ran her tongue over his junk, from his fat blue ballsack all the way to the tip of his dick. “Mmm,” she said, lifting her head slightly, “very tasty. Can’t wait for it to plump up…”

She went back down on him, drawing her tongue over the length of his dick. There was no real technique to what she was doing; she was just licking at his cock like a popsicle, satisfying her hunger with the flavor of Oval’s manhood. “Mmm, I can feel it,” moaned Oval, “I’m gonna get big for you, Dashie… make me big so we can crush this town together…”

Dash licked faster, moving her attention up and down his junk. One moment she was focused on his balls, flicking at them with the tip of her tongue - and then she was attacking the head of his cock, overwhelming him with sensation. Groaning, mutely gasping, Oval Office grabbed for buildings to steady himself against - only to have them crumble in his grip. When his grasping hands had demolished every building within reach, he clawed at the ground, shivering as climax built inside him.

He came, his load splashing against Dash’s huge, wet tongue. And that first spurt of cum, enough jizz to overflow a swimming pool, was accompanied by a surge of growth. He grew at least a hundred feet in that first instant - his shoulders knocked buildings aside as she grew, and his weight cracked the pavement, creating a deeper crater beneath him. His cock pulsed with rapid, powerful throbs, each one firing another thick splatter into Dash’s mouth.

Rainbow Dash’s moans were sounding happier and happier each time she got another taste of Oval’s cum. She could see and feel him growing, and she sucked eagerly at his lengthening cock as her hands stroked his toned thighs. He grew in earth-shaking bursts, each surge of expansion leveling more and more of the city around him - until, panting, his cock shot its last gush.

“Not bad,” said Rainbow Dash, running long fingers over Oval’s chest, “but you’re still too small. So, ready or not, you’re gonna fuck me.””

Rainbow Dash was still twice Oval’s size, easily - and so she completely overshadowed him when she crawled atop him. Her face, all in shadow, was wide-eyed and grinning, and her tits hung threateningly above his face, ready to smother him at any moment. “Ready to go again?” she asked, lowering her hips until her pussy lips brushed against the head of Oval’s stiff cock. “You gonna rise to the occasion, Oval? You made me cum long and hard last time, made me grow so fuckin’ big… now it’s time for you to catch up.”

She centered her womanhood over Oval’s cock and slammed her hips down, engulfing him completely. Her cunt was somewhat spacious at first - owing to her size - but when she flexed her pussy muscles, her slick walls grabbed his shaft tightly. “You ready to get big for me, Oval? I want to fuck up this little town, and I wanna do it with you. But for that to happen, you gotta get big for me.” She began to pump her hips, sliding her pussy up and down his length. “You ready to grow, baby? Tell me you wanna be big and strong for me…”

“Yeah, I wanna grow, I wanna get big for you, Dash,” gasped Oval, writhing beneath her. “My cock’s gonna grow… gonna get big enough to fill you up…”

“That’s the spirit,” growled Dash. “Having a cute little boyfriend on my shoulder is fun, but what I really need is a man.” She pumped her hips harder, slamming them into the ground, deepening the crater under Oval’s firm blue ass. “Tall… broad-shouldered… rippling with fuckin’ muscle… with a big… fat… cock!” Holding his shaft tight in her tensed pussy, she rode him hard - he felt his cock surging with arousal again, despite his recent orgasm.

Oval’s cock was already well over thirty stories tall, big enough to smash buildings apart with a casual swing. But Rainbow Dash was a lot of woman now, tons and tons of curvaceous womanhood, and she needed Oval to be huge. “Mmph, make me big,” groaned Oval Office, “I wanna be big enough to fuck you for real. I’ll give you all the dick you can handle, deep and hard… I wanna get so big I can give you miles and miles of cock…”

“Hell yeah,” hissed Dash, “Hell yeah, dude, hurry up and cum so I can watch that hot bod get bigger... I need you to give me that giant dick.” She descended on Oval Office, burying him beneath her colossal sky-blue body. Her tits smothered him, covering his face completely, as her hips jackhammered at his crotch. He couldn’t breathe at all - when he tried, all he got was a tiny bit of warm air that bore the fragrance of Rainbow Dash’s soft skin.

He could barely move - every part of him was pinned down by Rainbow Dash. Her hands were holding down his wrists, her legs were holding his legs in place, and her tits were smushed against his head, blocking out all light and air. He couldn’t move, and he couldn’t possibly escape. He could suffocate here, beneath her tits, as she fucked him relentlessly.

Rainbow Dash’s lovemaking was relentless, brutal - a sort of revenge for the way he had made her cum her brains out. From base to tip, she gripped his dick with pussy muscles that could crush a skyscraper flat. He moaned into the pillowy flesh of Dash’s tits, his voice muffled into silence by breasts as big as football stadiums. His balls tightened, and his hips jerked, and he felt growth exploding in every nerve of his body…

Dash felt Oval’s quivering body grow tense beneath him, and then she felt his cock throb inside her, fighting against the iron grip of her pussy muscles. At first she held him tight, overpowering him easily - but then his cock grew, gaining almost a hundred feet of length in a fraction of a second. It pushed back against her inner walls, forcing her to loosen her grip - and now that his dick wasn’t so constricted, the first gush of cum rocketed up his shaft and exploded from the tip.

“Fuck yeah, dude!” she yelled out, her voice shaking foundations all over the city, “Hit me with that load! Get big, you fuckin’ sexy animal!”

And Oval did get big. Dash felt herself rising up on a cushion of firm flesh - of gorgeously toned manliness - as each pump of cum, each spasm of climax made him bigger and bigger. She felt his cock filling her pussy, taking up every inch of space until he was snug… and then one last surge of growth made it a wonderfully tight fit. He was finally big again. The perfect size, from head to toe.

Oval Office gasped for air as his growth freed him from Rainbow Dash’s suffocating tits. He saw her beautiful, grinning face - a bit flushed and sweaty, but still gorgeous. He wrapped his arms around Dash’s body and pulled her closer, lifting his head to meet her lips. She joined the kiss eagerly, opening her lips to let Oval’s tongue probe her mouth. This time Oval took command of the kiss - his most recent surge of growth had filled him with confidence, not to mention a raging passion.

He twisted his body, rolling to the side and taking Rainbow Dash along with him. Their rolling bodies demolished a whole district of the city, smashing old brick buildings and knocking statues to the ground. Oval pulled back from the kiss, looking down at the beautiful girl beneath him. “I was really hoping to make you cum,” he said. “Guess I wasn’t big enough, huh? But I know I am now.” He pumped his hips, working his cock out and back into her pussy.

“Don’t worry, big guy,” said Dash. “I was holding myself back on purpose… and it wasn’t easy. I just didn’t want to cum again before you did. If we came together, we’d both grow. And I’d be bigger than you again, and I wouldn’t get my big man back. I need you huge, so you can fuck me for real.”

She brushed a lock of yellow hair away from her eyes. “And now that you’re nice and big, how about you fuck me for real?” She rolled her hips. “Now that you’re a god, what do you want to do with that divine cock?”

“I’m glad you asked,” said Oval, with a devious grin. He pulled out of Dash, eliciting a long, lusty moan from her lips - and then he brought the tip of his cock to her bright blue asscheeks, sliding the slick member into her deep, dark buttcrack.

“Ooh, I like it,” said Rainbow Dash. “I’ve got this big round bubble butt… and I don’t even know what it feels like to get it fucked. I bet my ass is real tight… and I bet it feels fuckin’ great to have a cock in there.” She flexed her cheeks, squeezing the tip of Oval’s dick. “Just give me a little second to grab a toy, okay?”

She shook her shoulders, and Oval Office rolled off of her. Rainbow Dash stood up, setting her eyes on the center of the city and the still-standing tallest skyscraper. She couldn’t put a name to the architectural style of the building, but it shape was very inviting - it seemed like it was just the toy she was looking for. She knelt next to it, setting her fingertip on on its rounded top, and eyeballed its size. It was maybe eight hundred feet tall, to Dash’s five thousand - probably a bit longer than she needed, actually, but that wasn’t a bad thing.

She turned to Oval, making sure her man was watching - then she interlocked her fingers behind her head, straddled the skycraper, and bent her knees. The structure began to disappear into her, sliding up inside her immense womanhood… and soon she’d swallowed up all of it. Anyone still inside the building - if indeed anyone was - would have seen those massive wet lips sliding over the windows that lined the rounded building, dripping fluids down in thick streaks as they descended.

Dash flexed and bent her knees a few times, taking long hissing breaths as she felt the building enter her. Oval, enticed, came closer - and Dash reached a hand down to the base of the building and ripped it from its foundation. “Okay,” she said, “I’ve got my toy. Now get in this ass, big guy.”

She fell to her knees and leaned forward, supporting her body with one hand. The other hand, naturally, was still on the base of the skyscraper. She worked it gently around her pussy, keeping herself warm as she awaited Oval. And she kept her hips raised, gyrating them slowly to entice her boyfriend to hurry up and fuck her ass.

“Oh my god, get in me,” she groaned, looking over her shoulder as Oval positioned himself behind her. “I need it, Oval. I need it more and more the bigger I get… I think we’re just gonna have to grow forever, because every time I see that dick get bigger just want it more… and every time I get it I just want to see it get bigger.”

“Sounds good to me,” said Oval. He knelt behind Dash, parting her ass with the head of his cock, seeking out her pucker. “I can’t think of anything I’d rather do than grow with you, forever.”

He positioned himself at her asshole, wrapping his hands around her hips for balance. “Just let me know if I’m too big,” he said - and then he thrust.

Dash grunted in shock as Oval entered her. His cock had been a snug fit in her pussy, but in her ass it was brutal. She was feeling every inch of that skyscraper cock, her ass crying out as it was stretched by the girth of his colossal blue member. His cock was a hundred feet wide, big enough to demolish anything build by human hands. Big and strong and thick enough to fuck a hole through a mountain. And it was hammering at Dash’s ass, plunging deeper with every thrust.

Dash struggled to form words, but each ramming thrust made her gasp feebly. She was going to beg Oval to slow down, to give her a second to adjust - but the more thrusts she took, the better it felt to be stretched. The pain faded, and now each thrust just sent a jolt of pleasure through her pussy. “Fuck yes, dude, hit me deep,” she groaned, “Give me everything.”

“You’re so tight, Dash,” Oval grunted. “Am I big enough for you back here? Am I your big man again?” He hammered away at Dash’s ass, sending an intense rhythm of shockwaves through the city. Cracks spread out along the ground, centered at the spot where Oval’s hips slammed into Dash’s ass like a meteor strike.

“Oh yeah,” Dash gasped, “you’re so fuckin’ big, Oval… and I need you to cum inside me, baby, I need you to grow bigger inside my big thick ass... “ She worked the skyscraper in and out of her pussy, gliding its rounded edge against her clit. “Mmm, I gotta cum too… from now on we’re gonna grow together, baby…”

Applejack sprinted forward, pumping her powerful legs as she struggled to keep her footing on the violently quaking ground. The closer she got to the two giant lovers, the more the earth shook - but her enhanced body was strong enough to stay upright. She was almost at Rainbow Dash’s thumb - a hundred-foot-tall thumb whose fingerprint was a labyrinth of enormous blue whorls.

Applejack clutched Dash’s geode in her hand, and she felt its magic start to wake up as she drew closer to Rainbow Dash’s body. That was a good sign. This plan really might work.

When she came to the last thirty yards, Rainbow Dash’s hand abruptly lifted into the air - and then slammed back down to earth as Dash’s high, raspy voice cried out deafeningly. She was coming.

Dash’s hand came rushing at Applejack. But it wasn’t just coming at her - it was expanding in all directions as her climax made her body grow. In an instant, Applejack was swept up by Rainbow Dash’s body, tumbling onto the back of her giant hand. She clung to the growing expanse of soft blue skin, pressing Rainbow Dash’s geode stone against the giantess’ body.

As Rainbow Dash came, her ass clenched around Oval’s cock, seizing tightly on his cock. He gasped, his body tensing, and his skyscraper cock pumped a thick white lake of spunk up from his fat, dangling balls. They came together, and they grew together. They spread over the city, crushing everything flat with their huge, perfect bodies…

“Now! It has to be now!” yelled Sunset Shimmer. Dash and Oval were growing at incredible speed, and there was no telling when it was going to stop. Even here, at the outskirts of the city’s suburbs, they might not be safe.

Twilight clutched her geode stone in one hand, placing her other palm on a complex array of crystals - a sort of magical circuit board - that she’d assembled hastily on the drive over. Twilight’s geode glowed, resonating with the crystal array - and the other girls’ geodes joined in the resonance, surrounding them with a prismatic glow.

All they could do now was hope - hope that Applejack had made it to Rainbow Dash’s body, hope that the resonance would reach Dash’s geode, hope that the spell would actually work. And it needed to work quickly, because there was a tidal wave of flesh coming at them. Rainbow Dash’s right foot, blue as the sky and nearly as large, was about to roll right over them…

And then it was gone. There was nothing looming over them but the sky, the real sky, swirling with soft, gentle clouds. It was a moment before any of them looked down - but when they did, they saw Oval, Dash, and Applejack lying woozily at their feet. Oval was still inside Dash, his body twitching with the last moments of climax… but they were both back to normal size.

Then they turned their eyes upward, towards the ruined city. “You know,” said Rarity, “I also managed to get the geodes to rebuild my family’s lake house, but this… Hm. This seems like a rather large project for us to tackle.”
