The Big Second Date

“As someone with a lot of experience cleaning up magical messes,” said Princess Twilight Sparkle, taking a seat on Applejack’s bed, “I think we can declare this one solved.”

“We really can’t thank you enough,” said Sunset Shimmer. “Even with magic, I wasn’t sure there would be a way to fix all that… destruction.”

“Well, it certainly wasn’t easy,” sighed Twilight, casting her mind back to the myriad spells and artifacts she’d employed to reverse the damage caused by the sexual rampage of Oval Office and Rainbow Dash. “But even though magic was what turned those two into giants, the destruction they caused was… essentially non-magical in nature. And that makes it easier to clean up after them.”

Twilight Sparkle - this world’s Twilight Sparkle, who went by the nickname “Sci-Twi” when the princess was in town, looked sheepishly down at the floor. “But… when a problem is caused by magic…”

“Sometimes it can be trickier, yeah,” said Princess Twilight, giving her counterpart an understanding smile. “The way you mixed spells to create the original potion, then piled on spells trying to fix it, is sort of the magical equivalent of… tying a knot in a piece of string, then locking the string in a bank vault, then filling the bank vault with glue, then encrypting the glue with a computer.” She paused. “Is that something a computer can do?”

“No,” said Sunset.

“Well, anyway,” said Princess Twilight, “That’s why we can’t just shrink Dash and Oval. The spells are all tangled up.”

“...Sorry,” muttered Sci-Twi.

“There’s no need be sorry,” said Princess Twilight. “It’s sort of impressive, actually - if it’s any consolation, you made very inventive and clever mistakes, which are the mark of a true prodigy. But solving this problem could take a while. I’ll be going back to Equestria; now that I’ve taken readings from Dash and Oval, I can do better work in my castle’s lab. I’ll keep you updated on my work, and I’ll let you know when I have something for you.”

“All right,” said Sunset. “We’ll keep an eye on those two while you’re away. And… we won’t try to do any more magic to them.”

“That’s probably for the best,” said Princess Twilight. She turned to the window, meeting the two giant eyes that were peering into Applejack’s second-story bedroom. “How about you two? Any questions?”

“Can we still fuck?” asked Rainbow Dash. She leaned forward, so that her huge magenta eye dominated the frame of the window. At a hundred feet tall, she and Oval had to lie on their bellies, side-by-side, in order to peer into the second-floor window. For the first time, they had some giant clothes to wear - another product of Princess Twilight’s magical help.

Sunset sighed. “It’s really reassuring that that’s your top priority,” she said.

“It’s important!” said Dash. “Do you trust the two of us to keep our libidos in check until Twilight figures out a cure? We gotta know if me and Oval Office need to be tied down or something.”

“You should be fine,” said Princess Twilight. “The enchantment we cast should dissipate the buildup of sexual energy and prevent it from causing any growth. But you can contact me if there’s any trouble - I’ll be staying close to the portal on my side, so I be here quickly if I’m needed.”

“All right,” said Rainbow Dash. “We’ll try and keep each other under control.” But her hand was already reaching over to squeeze Oval’s firm buttocks, and her heart beat faster as her fingers pressed into the curve of his perfect ass.

“That field comfy enough for y’all?” asked Applejack, leaning out her bedroom window. Sunset and the two Twilights were gone, driving back to CHS. “Y’all can stick around till Twilight fixes ya up… just try not to knock down any more apple trees if you can avoid it.”

“Sorry about all this,” said Oval Office. “We’ve put you through a lot of trouble already.”

Applejack sighed, slumping against the frame of the open window. She had the same physique as Rainbow Dash - toned limbs, huge rack, bubble butt - thanks to the growth magic she’d been exposed to, but she was only a little over six feet tall. “Don’t worry yourself none,” she said. “I mean, it’s frustratin’ to deal with y’all’s libidos, but we sorted out Sunset and Twilight by bein’ forgiving and understanding, and I figure that’s still the right play. Plus, I haven’t forgotten how horny I got back when I was growin’...”

“Well, I think we’ve calmed down since… last time,” said Oval.

Applejack scoffed. “You say that,” she said, “But I see Dash’s hand grabbin’ yer butt. The princess says y’all can fuck if you want, so go ahead and get it out of yer system if ya need to.”

“Is that really okay?” asked Oval Office. “Right in your backyard?”

“You’d rather I change my mind?” asked Applejack, with a smirk.

“Thanks, AJ,” said Rainbow Dash. “We’ll try to keep it down.” She let the hand groping Oval’s butt creep down between his legs, tickling his balls and the base of his cock. Oval shivered, squirming in Dash’s grip, and an awkward smile broke out on his face. Applejack, apparently not in the mood to watch passion unfold, closed the window and pulled the blinds.

“Looks like we’re alone,” said Rainbow Dash, cozying up to her boyfriend.

“Well, I don’t know if it’s possible to really have privacy when we’re this big…” said Oval.

“Well, when have we ever cared about privacy?” asked Rainbow Dash. “You and me, we fuck wherever we want, whenever we feel like it, and we don’t care who sees!” She lifted her hand from Oval’s crotch and stuffed it down the back of his pants. “I’m so glad Twilight made us these giant clothes,” she said. “Now I get to undress my big sexy boyfriend.”

“You can’t get enough, huh?,” laughed Oval.

“Of you?” said Dash. “Never. No matter how big you are, and no matter how much of you I get, I always want more.” She snuck her other hand under his shirt, caressing the dark blue skin of his abs. “Don’t you want more of your Dashie?”

“I do,” said Oval. “I’m just worried this is gonna turn into, you know… losing control, getting bigger…”

“Don’t worry, I’m not losing control,” said Dash. “This is just how a girl’s body reacts when she’s lying next to a hundred-foot-tall hunk who’s all hers.”

“So this is just… perfectly normal affection?” asked Oval. “Just two horny, sexy giants doing what comes naturally?”

“That’s right,” said Dash. Her fingers began to fumble with the fly of Oval’s pants, and Oval rolled over to give her easier access. “Just two… sexually mature… young adults… who are going to going to have earth-shaking sex.” She unzipped his fly and tugged his pants away from his waist. “Now wriggle out of those jeans.”

Oval tugged his pants down to his ankles and gingerly kicked them off, taking care not to drop them onto any apple trees. His pants were heavy enough to crush a few dozen trees if they happened to land on them, and he wanted to keep the destruction to a minimum.

He pulled at Rainbow Dash’s shirt, tugging it over her head as she raised her arms - and Dash, not being quite as cautious as Oval, brushed her arms over the tops of about twenty apple trees, shaking loose bushels and bushels of fruit.

With her shirt out of the way, Dash’s sky-blue breasts were out in the open. She had no need of a bra; magical breasts took care of themselves, standing firm on Dash’s chest, never sagging a bit. They were also irresistible; instead of moving on to Dash’s skirt, Oval buried his face between her breasts. Her tits were bigger than his head, and his face sank between them until he was enveloped in darkness and softness and the fragrance of her skin. He kissed her there, and then - steadying himself with both hands on her tits - he lifted himself back out of her cleavage, planting more quick kisses on the skin of her breasts as he ascended. He had her giggling now, as he kissed his way past her collarbone and up to her lips. “Do you feel like you’re losing control, Oval?” she whispered, wrapping her arms around him. “Do you feel like you’re gonna get real big and get all horny-crazy with me?”

“I feel a little like that,” said Oval.

“Well, that’s just called being horny,” said Dash. One of her hands went south, feeling up his twenty-foot cock through his boxers. “And I know how to fix that. I got the cure for horny right here.” She released his cock and grabbed him by the wrist, maneuvering his hand underneath her skirt. She pressed his fingers against her panties, right where her pussy had made it wet. “This’ll take care of you, baby,” she said, rolling her hips and grinding her pussy against his hand. “I’ll give you everything you need, all you gotta do is get out that big blue cock and fuck me.”

“You want this cock, huh?” said Oval, tugging down his boxers with his free hand.

“I think you know I do,” said Dash. “I want it every day, as much as I can get it. I wanna get drilled by that twenty-foot shaft.” Oval got his boxers off, and was about to set them gently aside when Dash snatched them from his hand and tossed them in the direction of the Apple family farmhouse. They landed on the roof - and fortunately weren’t quite heavy enough to do any damage. They just draped themselves across one side of the roof, one leg dangling down just far enough to obscure a second-story window.

“There’s my big sexy giant,” said Dash. She sat up and grasped his cock, giving the veiny blue shaft a firm squeeze. She couldn’t get her fingers all the way around it - not even close, really - and the feeling of that big dick in her hands sent a shiver of pleasure through her body. All this growth had left Rainbow Dash with an insatiable appetite for big things, and Oval Office’s cock was very big and very tasty. She leaned her head forward and wrapped her lips around the head of his dick, dragging her tongue across the tip.

She hadn’t intended to give Oval Office’s dick more than a brief kiss, but the taste of his cock was irresistible. As badly as her pussy needed to be filled, the feeling of that big, beautiful cock in her mouth was too good to give up. She almost decided to just suck him off, let him cum in her warm mouth, and swallow gallons and gallons of his load.

But when her hand strayed down to her pussy, she reminded herself of just how much she needed him down there. She couldn’t deny herself that pleasure any longer, so she gave Oval’s cock one last lick and raised her head. Kneeling, she pulled down her panties and her skirt and carelessly tossed them aside; they draped themselves across several apple trees as they landed, snapping a few branches but fortunately not knocking down any trees.

“Looks like Princess Twilight knows her way around a spell,” said Rainbow Dash, looking down at her naked body. “Normally I’d be growing if I were this horny.”

“Me too,” said Oval. “Growing’s nice, but it’s also nice not to worry about crushing everything.”

“I already miss growing,” pouted Rainbow Dash, “But being huge is a pretty good compromise.”

She crawled on top of Oval, grasping his cock again as she positioned herself. “You know,” she said, “I kinda hope Princess Twilight doesn’t figure out a cure, you know? I mean, who would want to give up being huge? Getting to play with a cock this big… I’d be nuts to give that up.” She hovered over Oval Office, dangling her tits in his face, stroking the base of his cock. “Come on, I know you agree with me, dude. Don’t you want your Dashie to stay big?”

“I do,” said Oval, almost hypnotized by Dash’s breasts, “But-”

“No, no buts,” scolded Dash. “Don’t spoil the mood, dude. You and me are big forever, Oval Office.” She lowered herself onto Oval’s cock, sighing happily as she enveloped his cock with her warm, slick womanhood. “You’re always gonna be my big man… so tall and strong, with those big muscles and that big cock…”

Rainbow Dash started to bounce on Oval, quickly ramping up the speed and intensity until her thrusts were pounding his butt into the ground, creating two craters beneath his glutes. “Oh yeah, this is how it’s supposed to feel,” groaned Dash. “You get tons and tons of boob bouncing all in your face… I get twenty feet of dick filling my pussy…” She went in for a kiss, probing Oval’s mouth with a hungry, swirling tongue, pressing her tits against his chest as her hips continued to piston up and down on his cock.

Pulling back from the kiss, she met his eyes. “So am I right, baby?” she asked breathlessly. “Do you love being big? You like having a big cock?”

“Yeah,” gasped Oval Office. “Yeah, I like it…”

“And how do you like me?” demanded Dash, slamming her hips full-force onto his cock. “How do you like your Dashie?”

“I like her big,” groaned Oval.

“Fuck yeah you do,” said Rainbow Dash. She grabbed Oval by the shoulders and rolled them both to the side. If Oval had been expecting it, he might have resisted, for the sake of Applejack’s trees - but before he could react, they were rolling, and Rainbow Dash, now on the bottom, was crushing apple trees into splinters under her back.

“Now fuck me, you giant hunk,” Rainbow Dash commanded. “Drill me with that twenty-foot cock, pound my pussy so hard that it shakes every apple off every fuckin’ tree…”

“You got it,” said Oval, and he thrust, slamming his cock into Rainbow Dash with earth-shaking force. He’d already learned that Dash could take a pounding - and, in fact, she needed it hard and fast. Not surprising, really; Dash was all about going fast, and the growth potion had turned her from a star athlete into a paragon of physical perfection. She could take everything Oval could give her - every thrust, every hard, thick foot of cock - and she’d always want more.

“Aw fuck, gimme that big blue cock,” groaned Rainbow Dash, writhing beneath the hundred-foot-tall giant who was thrusting into her. She clawed at the ground as her arousal rose, digging up apple trees and carving trenches into the soil. Eventually, her hands found their way back to one of their favorite spots: grasping and groping at Oval Office’s perfect buttocks.

Feeling himself getting close, Oval grabbed Dash’s tits and squeezed, sinking his fingers into the soft, firm flesh. Dash’s pussy pulsed around his cock, tightening and squeezing his shaft. He couldn’t hold himself back any longer, not with those powerful pussy muscles massaging his thrusting cock…

Oval came, erupting in Rainbow Dash’s pussy, shooting gallons and gallons at a time as his cock pumped a giant-sized load into her. Dash, feeling the first gush his the back wall of her pussy, tightened her grip on Oval’s ass and pulled him deeper inside. Her cunt tightened around Oval’s shaft - and then it tensed rhythmically, pulsing with a climax that reached mind-shattering heights. She squirmed helplessly beneath Oval, crying out, grasping at his ass. And all the while, Oval Office was thrusting hard as ever, shaking the earth, still shooting gallons inside Dash.

The two of them fell limp, panting and sweating, staring into each others’ eyes. Oval rolled off of Dash and snuggled up next to her. “You know what’s nice?” he said. “I’m satisfied. If we were still growing, I’d just want to fuck forever… but now I can just relax with you… and hold you…”

“Yeah, it is nice,” said Dash, draping an arm over Oval Office’s chest. “I don’t know if it’s better than fucking and growing forever, but… yeah, I like this.”

“Well, yeah,” said Oval. “I mean, when I was crushing on you, I wasn’t just thinking about how we would fuck all the time. I was imagining how we’d lie next to each other. Kinda like this.”

“That’s what you were fantasizing about?” scoffed Dash. “I only thought about the exciting parts of dating you, dude. I mean, cuddling is nice and all, but if you’re gonna daydream, why not daydream about awesome stuff?”

“Well, first of all, this is awesome,” said Oval, “and I’m looking forward to our relationship being more than just sex, now that we’re not constantly-growing, rampaging sex giants. Once we’re back to normal size, we can go on actual dates, and go back to school… I mean, there’s not a lot we can do at this size, if we’re not willing to destroy whole cities.”

“You want to go back to school?” said Dash. “I know you’re an academic decathlete or whatever, but being a sexy giant is way cooler than being a high school senior. If we stayed this size forever, we could get jobs hauling heavy loads for a construction company and just spend the rest of the time fucking.”

“Is that really what you want to do with your life?” asked Oval. “I figured you had some kind of, like, athletic ambitions.”

“Well, sure,” said Dash, “But even if I shrink back down, I don’t know if it’s, like, ethical for me to compete against people who haven’t been enhanced by magic potions.”

“I mean, we might just get shrunk down to our actual original size,” said Oval Office. “Not just the six-foot-three super-sexy versions of ourselves.”

Dash sat up, her giant tits jiggling with the momentum. “Aw man, I don’t want that!” she said. “I have magically perfect boobs, I don’t want to give these up no matter what! Maybe we can just get Princess Twilight to peel off every other layer of magic?”

“Yeah, maybe,” laughed Oval. Rainbow Dash lay back down, resting her head on his chest.

“Okay, I’ve been tossing some theories back and forth with Princess Twilight,” said Twilight Sparkle, raising the magic journal so that Dash and Oval could see it through the window of Applejack’s bedroom. “I told her that the two of you are doing a good job of just… lying down and not going anywhere for the last couple of days… but since we don’t know how long a cure’s going to take, that’s not a great long-term solution. We think there might be a way for the two of you to actually, you know, walk around and stuff. Without crushing everything in sight.”

“You want us walking around?” asked Oval Office, raising an eyebrow skeptically. “Don’t you sort of try and keep magic stuff secret?”

“Speaking personally, as an aspiring scientist,” said Twilight, “I’m not big on veils of secrecy. That sort of thing seems like it would make peer review pretty tricky. And in any case, you two already caused a lot of damage. You probably haven’t been watching the news lately, but… well, the two of you aren’t exactly secret anymore. And short of magically mindwiping everyone on the planet and selectively deleting data on servers worldwide, you’re never going to be secret.”

“I guess that makes sense,” said Oval. “So what’s the plan?”

“It has to do with those geode crystals,” said Twilight. “See, I theorized that your crystal, Rainbow Dash, has the ability to dampen the effects of air friction.”

“No, it just makes me go really fast,” said Dash.

“No, I mean-” Twilight waved one hand in a hopeless gesture. “I just mean… normally if you moved that fast, it would cause all kinds of problems with air friction, g-forces… not to mention the force of impact if you happen to run into something solid. But the geode takes care of all that, without you explicitly asking it to.”

“Huh, yeah,” said Rainbow Dash. “So what does that mean for us now?”

“Well, I think the geode can dampen the impact of your footsteps, and your weight in general,” said Twilight. “It can keep you from cracking the pavement wherever you walk, and probably keep you from smashing buildings on accident.” She dug the blue geode crystal out of her pocket. “I mean, you still have to be careful. Don’t go breakdancing in the center of town or anything.”

“And this won’t make the growth magic go out of control?” asked Oval.

“Princess Twilight says no,” she said. “Magic potions, magic tablets, those are potentially dangerous… but anything outside your body isn’t going to have any troublesome interactions. Here, Dash, take this,” she said, dangling the crystal from her fingers and holding it out through the window. Dash took it, and found that it was hanging from a strap that was about thirty feet long.

Dash hung the crystal around her neck and looked quizzically at Twilight. “What now?”

“Just think about… walking around without crushing stuff. Leaning on a building without breaking it. Just try to… want that. You do want it, right?”

“Yeah, of course,” said Dash. “I mean, smashing stuff is fun, but-”

“Yeah, try not to have thoughts like that,” said Twilight.

“All right,” laughed Rainbow Dash. “Okay, thinking about… not crushing stuff…” She placed a hand on Oval’s shoulder. “Will the magic work on him too?”

“It should,” said Twilight. “Love and friendship are good ways to make ‘bridges’ for magical effects…”

The crystal glowed, and Dash and Oval shared a prickling, tingling sensation, their hair rising as if affected by static electricity. When the glow faded, Dash stood up, looking at her fingers, trying to detect if anything was different. “So how do we test this?”

“Since we determined that the crystals can also be used to rebuild structures,” said Twilight, “Applejack agreed to let us use her barn to test it out. Go ahead and sit on the barn, see if your big butt turns it into splinters.”

Rainbow Dash laughed, walking over to the barn. “You’re lucky I like being told I have a big ass,” she said. “If it turns out I can sit on things without crushing them, I might just sit on you.” She straddled the Apple family barn, positioned her ass above its roof, and slowly lowered herself down, gingerly settling her weight down on it. And although a hundred-foot-tall girl should have been more than heavy enough to collapse the barn into splinters, the barn held its shape, only creaking slightly as Dash’s gigantic ass rested on it.

“Hey, it worked!” said Rainbow Dash. She leaned in the direction of the farmhouse, making eye contact with Twilight. “You wanna take me up on that offer?” she asked. I can sit this big ass right on top of you, Twilight. Clothes or no clothes, dealer’s choice! You’re cool with it, right, Oval?”

Oval Office just laughed. Twilight lowered her head, her face growing flush. “Anyway,” said Twilight, “You should be able to walk around without breaking everything in your path… but do be careful, okay?”

“This feels weird,” said Oval Office.

“Aw, you got butterflies in your tummy?” laughed Rainbow Dash, nudging Oval in the ribs with her elbow. “That’s just what happens when you go out on a date with a pretty girl.”

The two of them were almost in town. For them, the walk down the country road that led into the city was a casual stroll; walking arm-in-arm, their hundred-foot strides brought them easily to the edge of the city proper, where homes and strip malls gave way to gleaming glass skyscrapers.

And those skyscrapers weren’t the only things attracting attention with their size. As Oval and Dash strolled through increasingly populated areas, more and more people were staring up at them, craning their necks to see the bodies of the big, sexy giants in their midst.

“There’s a lot of people watching us,” said Oval.

“That didn’t bother you before,” said Dash.

“Yeah, but every other time, we were sort of…” his voice dropped to a whisper. “Hypnotized by horniness.” He waved awkwardly at a woman walking her dog. “But now that I’ve got a clear head I’m, like, super aware of being looked at.”

“Well, if it makes you feel better,” said Dash, “Everyone who’s looking at you is in awe of that big hunky body.” She grabbed his t-shirt and pulled it up, exposing his perfect abs. Oval yelped and swatted her arm away letting his shirt drop. “Come on, dude,” laughed Dash. “This body’s a feast for the eyes, and I don’t mind giving the little people a little peek. I know I’m the only girl with a big enough appetite to gobble up that yummy bod.”

“I don’t know if I want to go around flashing people,” said Oval, smoothing out his shirt.

“You should want to show off that body, dude,” said Dash. “And you should dare me to flash my giant boobies. She tugged the hem of her shirt upward slightly, exposing her belly button and a bit of sky-blue midriff. “Do you dare me?”

“Uh, nah,” laughed Oval.

“Well, think about it,” said Dash, letting her shirt drop. “So what are we doing? What do a couple of sexy giants do on a date?”

“Ooh, I know! I know!” said a little voice from the vicinity of Oval Office’s hips. He looked down and saw a little puff of pink hair wriggling out of the front pocket of his jeans.

“Pinkie?” said Dash. She and Oval stopped in their tracks and knelt to look this newcomer in the eye. “Why are you in Oval’s pocket?”

“Because your clothes don't have any pockets!” said Pinkie. “It's a very common problem with women’s fashion, and I don't see Rarity doing anything to fix it!”

“No,” said Dash, “I mean-”

“I guess I'm being a little hard on her, though,” said Pinkie Pie, seeming to ignore Dash. “I mean, she's just a high school senior, you can't expect her to make really big waves in the fashion world just yet, even if her Insta is super popular. She hasn't even gone to fashion school yet - oh! Did you hear? Rarity got that fashion scholarship she was after!”

“I didn't hear that,” said Dash. “That's really cool, but I was really asking why you're here at all.” Before Pinkie could speak, Dash raised her hand in a prohibitive gesture. “And just answer the question, don't go off into ‘why are any of us here?’ Or something that that.”

Pinkie shot Rainbow Dash an exaggerated scowl. “Dashie, please,” she said, “I'm not a hack.” She wriggled upwards slightly, resting her elbows on the stitching of Oval’s pocket. “I'm here because I'm an event planner, and clearly neither of you know how to have fun when you're a hundred feet tall!”

“So you're planning our date?” asked Oval.

“If you want it to be cool and fun, then yeah!” said Pinkie. “I'll just tag along in Oval’s pocket. You'll barely even notice me, except for when I occasionally bump into Oval’s giant penis!”

“So that's what that was,” said Oval.

“Yeah, that sounds good,” said Dash. “I trust you to plan out a fun date, and I mostly trust you not to get too fresh with my boyfriend’s huge dick.” Pinkie giggled. “So what are we doing first?”

“Well, you guys already ate, right?” asked Pinkie.

“Yeah,” said Oval. “Sunset’s got us on a diet of magically enlarged food.”

“Fun!” said Pinkie. “But what would be even more fun is shoveling tons and tons of normal-sized food into your giant mouths! So we're getting dessertat Sugarcube Corner!”

With a hundred-foot-high perspective, it was easy to spot the cupcake-topped facade of Sugarcube Corner. Oval and Dash cautiously stepped through the streets, planting their feet on empty sections of the road and carefully tiptoeing through backyards. There was the odd bit of panic here and there, but no damage; thanks to Dash’s magic, they left nothing more impactful than some shallow footprints in the grass.

Sugarcube Corner shared a parking lot with several other small eateries, and Dash and Oval knelt in that lot and carefully lowered themselves onto their butts. Oval reached down to retrieve Pinkie from his pocket, but she was already hoisting herself out and dropping to the ground. It looked like a perilous drop, but Pinkie landed easily on her feet and skipped towards the back door of Sugarcube Corner. She unlocked it, disappeared inside, and returned with a rolling rack of cakes - and then she hurried back inside and rolled out another one.

“I stole forty cakes!” said Pinkie. “JK, we just had a huge order that got canceled.”

“And we can just eat all these?” asked Oval.

“Yup!” said Pinkie. “It’s you or the garbage! Enjoy!”

Dash plucked a pink-frosted cake from the top rack of one of the carts. To her, it was just a tiny morsel, barely big enough to be called bite-size. She set in on her tongue, savored it for a moment, and then swallowed. “Mmm, good stuff,” she said, grabbing another one. “Hey Oval, open wide.”

Oval stuck out his tongue, and Dash dropped the cake onto it. “Mmm, I like it,” said Oval. “So are we gonna stop at one cake each, or…”

“Hell no, dude,” said Dash. “I’ve been a lustful giantess for a while, now I’m gonna try being a fuckin’ gluttony monster.” She carefully pulled a rack of four cakes from the cart and held it over her face, letting the cakes slide into her mouth. “Ahh, that’s a good feeling,” said Dash. “Eating inhuman amounts of food, while everyone’s watching… and I bet this body’ll stay perfect, no matter how many cakes I eat.”

“Well, these cakes are pretty tiny,” said Oval, lifting a tray from the cart. “But yeah, there are a lot of people watching, huh?” He held the tray up to Dash’s mouth and let her lick the cakes off of it.

“Yeah, we’re getting lots of attention,” said Rainbow Dash. She felt around on the parking lot behind her, testing the ground to see if there was space for her to lie down. There were a couple cars parked behind her, so she lifted them up and gently placed them in nearby parking spots, then lay herself flat on the asphalt. “Hey, little people,” she said, tracing her fingers along the parking lot, lightly bumping a few of the gawking humans with her fingertip. “What do you think of me?”

The response from the gathering onlookers was varied in tone and volume, and there was no way to tell what any individual was saying... but they seemed excited about the beautiful giantess with the rainbow hair. “Yeah, that’s what I like to hear,” said Dash. She reached over to the cake cart, grabbed another tray, and dropped another four cakes into her mouth. “I don’t even need to be good at anything!” she said. “I can just sit around and be huge and hot, and all these tiny people will be cheering my name!”

“How about this, Oval?” said Dash. “Instead of shrinking back down, we just build up a fan club of tinies who want to worship and serve us! I know some of these little guys would devote their lives to me if it meant they could bounce on my tits every now and then!”

“I don’t know about that,” laughed Oval.

“Come on, you don’t have to be jealous of a bunch of little dudes,” said Dash. She stretched her arms and arched her back, thrusting her tits upward. “You know you’re the only man who can satisfy me. Speaking of which, I bet there’s some tiny ladies who’d pledge their lives to you if it meant getting to play around with a twenty-foot-long you-know-what.”

Oval Office felt embarrassment start to gnaw at him as the crowd reacted to what Dash had said. But he couldn’t help but feel good about the attention he was getting; all those people were imagining his colossal cock - and even if they weren’t responding with desire, they were certainly in awe at the size of his member.

He felt the evening air on his chest as Rainbow Dash - once again - lifted his shirt and exposed his abs. “And how about this chest, huh?” she said, running her fingers across his perfect musculature. “I bet some of these girls would kill to oil up a set of giant abs!”

“Are you sure that’s what girls like?” asked Oval.

“I think you’re underestimating your raw sexual power, dude,” said Rainbow Dash. “And how are you gonna know how many tiny women you can snag if you don’t give it a try? Twilight could come up with that cure tomorrow, dude, and you’ll be back to normal. Live the giant life while you can, Oval!”

Oval took a couple more racks from the carts and licked up eight cakes in a matter of seconds; between the two of them, they’d nearly depleted the cakes Pinkie had rolled out for them. “I think we lived the giant life a little too much, back when we were smashing up buildings,” he Oval.

“Aw, just go for it!” said Dash. “It’s not cheating if the girl’s smaller than your cock. That’s a rule!” She reached out toward a group of young woman - but they all scampered away from her hand, huddling against a wall.

“You shouldn’t have mentioned how we smashed up the city,” said Dash. “Now they’re scared of us.”

“You two done?” yelled Pinkie, leaning out the bakery’s back door.

“Yeah, we finished off those cakes,” said Oval. “What’s next?”

“I’m so glad you asked!” said Pinkie. “You know how drive-in movies aren’t a thing anymore?” Dash and Oval nodded. “Well, the next best thing is outdoor movie nights in the park! How do you feel about the Cobalt Spark films?”

“Derivative,” said Rainbow Dash. “Basically the same thing as Daring Do, but with worse action and a less interesting protagonist.”

“Well, Cobalt Spark: Beyond is the only film playing outdoors tonight, so that’s what you’re watching!” She climbed up Oval Office’s pants and wriggled back into his pocket. “Come on, let’s go! Daggerhill Park!”

The part, by the standards of giants, wasn’t far - just a few miles away. Rainbow Dash and Oval Office crested the eponymous hill just as the movie was starting, and every single head turned to look at the earth-shaking giants as they strolled up and planted their butts on the high ground. They kept watching Dash and Oval, waiting for them to do something… but the two giants wanted nothing more than to watch the movie, and they sat still. The rest of the crowd, on folding chairs and picnic blankets, eventually turned back to the screen to watch the opening credits.

“So…” whispered Oval, as the first action scene unfolded, Colbalt Spark grappling from tree to tree as enemy agents pursued her. “The Daring Do movies are better? I haven’t seen them.”

“Oh man,” said Rainbow Dash, her voice low, “We have got to marathon the Daring Do movies. Pop some giant popcorn, curl up together…” Dash leaned on Oval, putting her head on his shoulder and her arm around his waist. “A quiet night in, just you and me…”

They sat there like that, watching the film unfold, their arms around each other. Dash’s breaths were long and slow - except for the moments when the action managed to make her pulse race, and she tugged Oval closer. Oval looked down and saw her chest - her enormous chest, topped with globes bigger than her head - rise and fall peacefully.

It was a long, wonderful moment of normalcy. it was still obvious that they were both giants - in the fading light of day, the crowd of tiny moviegoers was easy to see - but to Oval, it finally felt that they were a boy and a girl on a date. Watching a movie, embracing one another, not in the thrall of magically insatiable sexuality.

Of course, there was still perfectly ordinary young-adult sexuality to content with. And when Cobalt Spark tumbled, breathless and glistening, into the arms of a rakish rogue… Oval felt Rainbow Dash’s fingers stroking his thigh. He stayed still for the moment, letting Dash’s had glide over the denim of his jeans… until the tips of her fingers brushed the place where his cock lay beneath his clothes. Then he sighed, and shivered, and put his arm around Dash’s waist, tugging her closer.

Oval felt his cock start to get harder, growing plump inside his pants. In truth, his dick was always pretty prominent; even soft, it was thick and long enough that its outline was easy to detect. The issue was only compounded when it began to grow, snaking its way down his pant leg as it approached its full length of twenty feet. Everyone would see what he was packing down there, if they weren’t all looking at the screen…

A white-hot explosion erupted on the screen, cutting short the action between Cobalt Spark and her co-star just before it would have given the film an R rating. The light illuminated the whole crowd, and Oval saw just how many people weren’t watching the screen. Maybe they’d been looking at Dash and Oval the whole time, or maybe his sigh had drawn their attention, but about a hundred of them were watching Oval get his dick groped.

“Dash…” whispered Oval, trying to keep his voice low enough to not attract any more attention - probably a futile effort, since his tremendous size made it difficult to speak quietly.

“I know,” said Dash, in an equally low mumble. “There’s people watching, right?” She kept stroking his thigh, putting a little more pressure on his stiff shaft. “Come on, you know by now that doesn’t bother me. I’ve got the world’s hottest boyfriend, with the world’s biggest cock, and I’m gonna enjoy it no matter who’s watching.”

“Like I was sayin’, dude, you gotta live the giant life while you can,” Dash continued. “The spotlight is a great place to be when you’re extraordinary. I always knew I was awesome… and the sooner you realize that you’re awesome, the sooner you can enjoy being the center of attention.”

“I guess you have a point,” said Oval. It did feel kind of good, having all those eyes on him as his girlfriend lewdly stroked his inner thigh. If he’d been at his normal size, he’d have worried that someone would approach them and call them out for their inappropriate display… but now the two of them were unstoppable. No one could stop them from doing whatever they wanted. “But… what’s your plan?” asked Oval. “Are you gonna jerk me off right here?”

Rainbow Dash dragged two fingertips slowly over the length of Oval’s cock. “Nah, I don’t think so,” she said. “I just wanna get you good and horned up for later. Plus, it feels good to disrupt a screening of a Cobalt Spark movie. Like I said, they’re derivative.”

“So we’re heading to the lake?” asked Rainbow Dash. Once the film had ended, Pinkie had emerged from Oval’s pocket once again and pointed them east, where the calm waters of the nearby lake reflected the light of the rising moon.

“Yup!” said Pinkie Pie. “I heard a rumor about a lakeside bonfire! Well, actually, I started a rumor about a lakeside bonfire, and thanks to my reputation as a party authority, the rumor became true!”

“Wow, nice work,” said Oval Office.

“Thanks!” said Pinkie. “I’m having fun tagging along with you two. The best part was when Dashie was rubbing your penis, and I sort of got sandwiched between her fingers and your dick!”

“Huh, that was you?” said Dash. “I thought there was kind of a bumpy spot. I didn’t hurt you, did I?”

“Nah, I’m squishy,” said Pinkie. She leaned out of Oval’s pocket, peering eastward. “Now where’s that bonfire?” she muttered. “They should be lighting it up any second now…”

Beside the water, a small red flame came to life. From the perspective of the giants, who were a hundred feet tall and still a couple miles away, it looked no bigger than a burning match head, but it illuminated the shapes of several little people - and it showed Oval and Dash exactly where the party was.

In the darkness, Dash and Oval were able to get pretty close before the partygoers noticed them - but when they got close enough that the bonfire’s flame illuminated them, a cheer rose from the partygoers.

“Yes, finally! Finally!” said Rainbow Dash. “Finally some cool people who are excited to meet some sexy giants!” She knelt next to the bonfire, grinning at the people who were crowding around her. “What’s up, guys? I’m Rainbow Dash, and I’m fuckin’ huge!”

“Hi, everybody,” said Oval, kneeling beside Dash. “I hope it’s okay that we crashed your party.” There was a chorus of encouraging voices; apparently it was totally cool that they crashed the party.

“Oh man, you guys got beers!” said Dash. “Are you college kids? I’m gonna have a beer. I’m gonna have exactly one beer.” she pulled a bottle from an ice-packed cooler, pinching its neck between two fingers. “Can someone open this for me? I got giant fingers over here.”

A guy with a popped collar took the bottle from Dash, removed the cap with a bottle opener on his keychain, then handed it back to her. She lifted the bottle to her lips, poured its contents onto her tongue, and tossed it aside. “Woo!” she shouted, and the partygoers echoed her sentiment. “Oval, I’m so drunk!” she said, affecting an exaggerated slur. “Let’s make out!”

“You are definitely not drunk off of twelve ounces of beer,” laughed Oval - but he did as Dash asked, wrapping his arms around her and pressing his lips against hers. She fell backwards, and Oval followed, draping himself over her and probing her mouth with his tongue. Dash embraced Oval - gripping the toned ass she loved so much, and grinding her hips against his cock. From all around him, Oval heard more cheers; the spectacle of two amorous giants was, apparently, a welcome addition to this lakeside gathering.

From somewhere nearby, music began to play - powerful, pounding music, from surprisingly powerful speakers. Rainbow Dash pulled back from the kiss, looking into Oval’s eyes with an expression that was almost manic. “Oh shit, dude, let’s dance!”

Oval chuckled awkwardly. “I can’t really dance-”

“You got an awesome body now, dude!” said Dash, rising to her feet. She took his hand and pulled him upward. “Just move that hot body and I guarantee it’ll look good! Just, uh…” she looked down at the partygoers. “You might wanna give us a little space, okay? Just in case Oval herereally does suck at dancing.”

The little people backed off a bit, and Dash led Oval a few steps away from the bonfire. Someone turned up the music, and Dash started to dance, raising her arms, shaking her hips and waving her long rainbow locks back and forth. She shot Oval a few expectant looks, thrusting her jiggling tits in his face.

Hesitantly, Oval started to dance, doing his best to mimic Dash’s movements. Dash smiled encouragingly, dancing closer to him, thrusting her hips and shaking her tits to the pounding beat. Oval began to move a little more confidently, and he was certain he looked like a total doofus… but he didn’t care about that too much, and that seemed to matter more.

Both of the giants were bringing their feet down hard on the ground. The partygoers were keeping themselves at a safe distance, but they were struggling to remain standing when the earth was shaking so frequently. They danced with each other in the light of the bonfire, or they simply drank their beers, staring up at the sexy titans. Rainbow Dash’s rhythmically wobbling tits and ass got a lot of attention… but so did the outline of Oval Office’s giant cock.

It didn’t take long for Dash’s dancing to turn overtly sexual. She ground her hips against Oval’s, draping her arms across his shoulders, keeping intense eye contact as her body swayed. She bent at the knee, slinking downward, and Oval kept moving his hips as he waited for her to come back up.

But she didn’t come back up. She stayed down there, no longer really dancing… and Oval began to feel a tugging at his pants. Dash was unzipping his fly, pulling his pants down to his ankles - so Oval stopped dancing, and just let Dash do what she was doing. In a different state of mind, he might have voiced an objection, but at this point he was horny enough to just go along with it.

Dash pulled down his boxers and let them fall to his ankles - and when they fell, they sent out a gust of air that made the bonfire dance. Dash stared adoringly at Oval Office’s cock, holding the base of the twenty-foot shaft in her fingers - and shooting a look in the direction of the tiny partygoers, proudly showing off the giant dick that she had the privilege of sucking.

And then she started to suck it, kissing the tip and then embracing it with her plump lips. Cradling his balls with her fingers, she took him deeper - five feet of cock, then ten feet… he looked down and saw her eyes staring up at him, and her lips smiling around a mouthful of cock. As she maintained eye contact, she dragged her tongue over the underside of his cock, caressing the bare skin of his shaft and making him moan and shiver.

“Oh man,” moaned Oval, weaving his fingers into the hair on the back of Dash’s head, “Dash, oh my God... “ Dash became bolder, taking more of his dick, deep-throating his twenty feet of dick. The tiny partygoers around their feet were impressed with Rainbow Dash’s blowjob prowess, woo-hooing as they saw the bulge of Oval’s cock showing in her throat.

Oval looked down at the tiny onlookers, reading the awed expressions on their faces. Dash had been right - it was nice to be appreciated for his size and virility, even if it was just by a bunch of drunk college kids. Oval didn’t want to be scary, like he was back when he and Dash were smashing up buildings… but he did enjoy the sound of little people cheering him for getting a blowjob.

And the blowjob itself wasn’t half bad either. Oval felt his nuts pulling up against his body, readying themselves to release gallon after gallon of spunk. And Dash was greedy for it, her throat making wet noises as she eagerly sucked his shaft. It wasn’t surprising that an appreciative crowd was bringing out the best in Rainbow Dash; she was at her best when she was in the spotlight, and now she wasn’t just sucking a dick. She was performing. She was going to prove she was the best at blowjobs. She was sucking the biggest dick and she was going to swallow the biggest load…

Oval came, shooting the first few dozen gallons right down Rainbow Dash’s throat. Dash leaning away from his body, sliding his cock out of her throat, letting his next spurt land on her tongue - and then she pulled away entirely, popping his cock out of her mouth and gripping the base of his shaft. Laughing, she angled his dick to the side, aiming it down at the little partygoers. Before they could react, the first giant jet of cum shot in their direction; it only landed between two clusters of people, leaving a thick white streak on the ground.

The drunken college kids had been excited to watch a giant blowjob, but they were a little less happy to be dodging gigantic spurts of cum. Dash giggled cruelly as she aimed Oval’s cock, trying to nail her tiny fans with each gush of spunk that shot through his shaft. Eventually, she scored a hit, knocking a couple girls to the ground and glazing them in her boyfriend’s cum.

With Oval’s orgasm winding down, Dash turned his cock towards the bonfire and let it shoot one last spurt, extinguishing the roaring flame. There were now shouts of anger coming from the little people, but Rainbow Dash just laughed - and Oval, leaning down to pull his pants back up, joined her in laughter. “Looks like the party’s over,” he said.

“Yeah, let’s get out of here,” said Dash. She took his hand and started to walk in the direction of Applejack’s farm. Oval gently patted his pocket, confirming that Pinkie was still there, and went along with Rainbow Dash.

“So you just… can’t fix it?” asked Oval Office. “Like, ever? At all?”

It was a lovely day on Applejack’s farm, despite the disappointing news. Sunset and the two Twilight Sparkles were once again seated in Applejack’s bedroom, facing the window and addressing the two giants. Princess Twilight, front and center, sighed and threw up her hands. “I know it seems like it’s too soon to give up,” she said. “It’s been less than a week, but I did the math - with a lot of help from Twilight and Sunset, and-”

“Wait,” said Rainbow Dash. “There’s math in magic?”

“There’s math in everything,” said Princess Twilight. “Anyhow, the spells in your bodies… the way they’re knotted up, you would need to precisely dispel their components, in exactly the right order, or you’d just make it worse. And mathematically, there’s so many possible sequences and no way to know which one is correct. It’s not impossible to cure you, but it’s… well, it’s just not going to happen.”

“Well, to be honest,” said Rainbow Dash sheepishly, “I did kind of want to stay big… so we just stay this way?”

“Not quite!” said Twilight. “Thanks to the your geode crystals, there may be a way for you to channel and control the magic inside you. Casting spells through a crystal actually isn’t too different from casting them through a horn, so I was able to develop and test a spell on my side of the portal. Once Sunset and Twilight cast it, the two of you should be able to control your sizes.”

“Wow, cool,” said Oval.

“‘Wow, cool’ is right!” said Sci-Twi. “I learned a ton about magic this week… although I’m still pretty far from Princess Twilight’s level. If I try any solo projects, I’m still liable to mess them up as bad as I did this one.”

“Don’t be so hard on yourself,” said Sunset Shimmer. “Don’t forget, all this is Rainbow Dash’s fault.”

“Yeah, yeah, we’ve all done terrible things,” said Dash, rolling her eyes. “Except Oval.”

“It’s true,” said Oval, “I am free of sin.”

“Okay, go ahead and cast the spell,” said Princess Twilight. “Dash, you should feel your crystal resonate…”

Sci-Twi and Sunset came to the window and closed their eyes in focus, and the crystals hanging around their necks began to glow. Pulses of orange and purple light flowed through the window and enveloped Dash and Oval - and then it faded.

“There you go,” said Princess Twilight. “Just sort of… try to change your size. It’s hard to describe how, but just... try.”

Oval concentrated on the thought of getting smaller, picturing himself at his normal size… and he saw Applejack’s house begin to rise. He lost ten feet of height in an instant, then shrank ten more feet just a bit slower… and by the time he was down to twenty feet tall, the mental effort of shrinking any further got to be too much for his. There was a limit, some sort of wall he was bumping up against; even with some control of the size-changing magic, he couldn’t be entirely rid of it.

At his hundred-foot height, he’d been kneeling to get his head level with the second-story window. Now he stood, twenty feet tall, looking at Sunset and Twilight through the open window. “I think that’s as small as I can get,” he said. “But hey, it worked!”

But Sunset and Twilight weren’t meeting his eyes. Instead, they were staring upwards at something behind him - and it wasn’t difficult to guess what it was. When Oval turned around, it wasn’t Dash’s face he saw, but her shoelaces - and so he looked up, and up, and up.

“Oh man, I had a feeling you were gonna try gettin’ small first!” said Dash, grinning down at Oval. She’d doubled her height, looking down at the farmhouse from two hundred feet up.“I bet you were thinking about going back to school, sleeping in a bed, all the boring stuff you can do when you’re small! Come on and get big so we can be awesome together!”

“Seems like it works in both directions,” said Sunset. “Are you both feeling all right? Not, like, super sexually aroused or anything?”

“Nah, just the normal amount,” said Rainbow Dash.

“Oval Office, can you get any smaller?” asked Sci-Twi.

“I don’t think I could get too much smaller than this,” said Oval. With some effort, he shrank down a single foot. “Yeah, that was kinda hard to do.”

“More importantly, how big can we get?” asked Rainbow Dash. “Growing this much was easy, so I bet I could get way bigger.”

“The important thing is that you can control it,” said Princess Twilight. “And it’s also pretty important that you don’t smash up Applejack’s farm any more than you already have. I doubt I can stop you from testing out your maximum growth,” she sighed, “But if you’re going to, maybe do it somewhere secluded.”

Rainbow Dash groaned. “Yeah, I guess Applejack has been pretty patient with us,” she said. “All right, I won’t get any bigger.” She dropped to her knees, and Oval stumbled to keep his footing as the ground shook. She leaned forward, bringing her face closer to him - and, likely on purpose, dangling her tits right in his face. “So are you about as small as you can get, dude?”

“Uh, maybe,” said Oval. “As long as we’re putting it to the test, I’ll really try and shrink as much as possible.” He closed his eyes tight in concentration, focusing on the thought of becoming small, of compressing himself down… it wasn’t easy, but he felt himself slowly creeping downward. He felt like he was hitting a wall, a hard limit that he wouldn’t be able to go beyond… but he powered through, straining himself mentally and physically, willing himself to grow shorter.

And then - just for a moment, there was a feeling of painful constriction all over his body. It was his clothes, Oval realized, growing tight - but that made no sense. First of all, his clothes had been changing size with him just fine… and secondly, he was shrinking. If his clothes weren’t changing with him, then they should be getting too big for him, not too small.

But after that brief moment, it no longer mattered - because his clothes exploded off of him, first tearing at the seams and then tearing everywhere. They fell off him in shreds, leaving him completely nude. He opened his eyes, and before looking down at himself he looked up at Rainbow Dash, whose eyes were very, very wide.

“Oh my God, dude,” said Dash. “Dude, oh my fuck. You’re a little… blue… beast.”

Oval looked down at himself and saw a new and unfamiliar body. The first round of growth had turned him into a hunk, with prominent muscles that looked very good naked. But those muscles, from head to toe, had grown bigger, bulging from every limb. He didn’t have the outlandish, exaggerated physique of a career bodybuilder, but he was huge - even though he’d managed to shrink himself down to twelve feet tall.

And then there was the matter of his cock. While his muscles might not have been completely outrageous in their size, his cock definitely was. It was four feet long, fully a third of his height and thicker than his hips, with dangling blue balls bigger than his head. “Holy shit,” he whispered, grasping the base of his shaft with both hands. It started to rise, throbbing slightly as it stiffened.

“Dude…” gasped Rainbow Dash, a droplet of drool forming on her enormous lips. “Hooooly shit…”

“What is it?” asked Sunset, craning her neck to try and see what Dash was reacting to. “Can you turn around for me, Oval?”

Oval turned around, pointing his rising cock at the second-story window the girls were looking out of. The two Twilights, almost in perfect unison, blushed and put their hands to their faces… and Sunset’s jaw simply dropped. “Wow,” said Sunset, almost laughing. “That cock is… really something.”

“This is.. a little unexpected,” said Princess Twilight, “But I think this is just a different… expression of the control you have over your growth. You should be able to change the size of different body parts individually; I’m guessing that it only happened by accident because you were reaching the lower limits of your size.”

“Wait,” said Rainbow Dash. “So I can, like…” She balled her hands into fists and hummed softly - and Oval, still facing the farmhouse, felt something big, heavy, and soft pressing against his back. Soon there was intense pressure on his back, enough that he would have been knocked flat if he weren’t a twelve-foot tall wall of muscle. He turned around and discovered an even larger wall of flesh - Rainbow Dash’s tits, growing bigger, stretching her green t-shirt to its absolute limit. Her breasts were the only part of her that was growing - unless you counted her smile, which was growing wider every second as she watched her tits expand.

Her shirt tore down the middle, and her colossal blue tits bounced out and slapped down onto the ground. They were individually three times bigger than her head now, and each far bigger than Oval Office’s whole body. “Oval…” said Dash, her breasts rising and falling with heavy breaths. “How do you like my giant tits?”

Oval leaned into her tits, sinking a foot and a half into her cleavage as her still-growing breasts pushed farther out from her body. He pressed his hands into their softness, groping and stroking the smooth surface. “I like them a lot,” he said.

“Well, I like that big hard cock,” said Rainbow Dash. “I like the way it feel between my boobs, Oval. How about you move those strong hips and fuck these giant titties, big guy?”

“Well, this was foreseeable,” said Sci-Twi, rolling her eyes. But although her tone suggested disapproval, she didn’t move away from the window, and neither did the other two girls. All three of them stumbled a bit when Dash’s boobs, still expanding, bumped against the side of the house, pinning Oval against the outer wall. Dash chose that moment to stop enlarging her tits, right at the point where any additional growth would have smashed in the wall of the house.

“Well, go for it,” said Dash, reaching a giant finger down to stroke Oval Office’s hair. “I got one hand between my legs, babe, and the one thing I really, really want is to feel that giant cock fucking my monster boobies!”

Oval was pinned between Rainbow Dash’s huge sky-blue tits, squeezed tight on both sides by the big, firm globes - and with the strength in his body, he probably could have wriggled free. But this was a nice place to be. He thrust his hips, sliding his four-foot cock deeper into her cleavage, feeling the firm flesh embracing his shaft. He pulled back and thrust again, quickly building a rhythm.

“Ooh, that’s nice,” whispered Dash. “These tits are super sensitive, and it feels real good to have a big fat dick sliding between them.” Her body was bucking back and forth as her fingers went to work on her pussy, and the motion of her tits was shaking the farmhouse down to its foundations. “How does that big cock feel, big guy?”

“Feels good,” said Oval, pumping his hips with greater speed and force. “I can’t believe how big my dick is…”

“Wanna make it bigger?” suggested Dash. “We’re supposed to test how well we can control our growth, right? How about you give yourself a few extra feet to play with?”

“Yeah, sounds good,” Oval gasped, and he focused his thoughts on growing his cock. He couldn’t see his dick - Rainbow Dash’s boobs had completely enveloped it - but he could feel it growing, adding on inches, thickening, and thrusting deeper. “I’m growing,” he groaned. “Fuck, it’s huge…”

“Yeah, make that cock big,” said Dash. “I wanna feel that thick blue dick, baby… I want you to shoot a big hot load deep between my boobs… I’m gonna cum so hard when you shoot that hot spunk, Oval. Are you gonna give me what I need, Oval?” she asked, leaning her colossal face down over him. “Are you gonna grow a big long cock and shoot a big sticky load?”

“Yeah,” said Oval. “I’ll give you everything I’ve got…” His hips were pumping with as much force as he could put behind them, slapping against Dash’s tits with each thrust. His cock, now six feet long and nearly as thick as his waist, was throbbing powerfully, readying itself to shoot, overloading his body with pleasure. His cock was enormous, so out of proportion to his body, and the pleasure signals it sent to his brain were so powerful that they nearly overwhelmed his senses. The onrush of climax was brutally intense, leaving him wordless, breathless as his body jerked and his cock erupted.

A gallon of thick, hot spunk shot from his tip, splattering the interior of her cleavage. His cock throbbed at a rapid pace, pumping a gallon at a time, drawing a huge supply of cum from his tremendously enlarged nuts. It was a different experience from just being big all over; having a cock and balls so out of proportion with his body turned the orgasm into a physically overwhelming experience, and he thrashed and writhed inside Dash’s cleavage as his cock shot again and again.

“Oh, that feels nice,” said Rainbow Dash, her fingers frantically flicking at her clit. “Lots and lots of hot sticky cum, all over my big giant boobs, and you just keep cumming and cumming… ohhh, I’m getting close too… gonna cum...”

Dash gasped and cried out as she came, and her bucking body made something inside the farmhouse crack loudly. Oval’s body bounced along with her tits, his cock still spurting cum, filling her cleavage with gallons and gallons of jizz. Groaning, he slumped down onto Dash’s tits as his climax ended, his cock weakly pumping the last of his load. Dash soon settled down as well, leaning her kneeling body forward, resting most of her weight on her enormous tits.

“Well, they can control their size,” said Princess Twilight. “Self-control might be a problem, though.” There was another cracking sound from somewhere in the house, and she reflexively flinched. “Girls, maybe you wanna use your crystals to keep this place from collapsing?”

“Look, I understand your concerns,” said Sci-Twi, “But you’ve gotta go to school!”

“Do we, though?” asked Rainbow Dash.

“Yes, you have to go to school!” said Sci-Twi. “Everyone has to go to school!” There was something intense, almost manic, about her insistence - as if pushing back would cause her to start yelling, or maybe burst into tears. She clearly cared a great deal about education; if Twilight Sparkle wanted you to go to school, chances are she’d find a way to make you.

Oval and Dash had walked to school at a comfortable height of fifty feet, and were contemplating the prospect of shrinking themselves down. “How small do we have to be before we can fit through doors and stuff?” asked Oval.

“Twelve feet should do it,” said Twilight. “I mean, you’ll have to crawl a lot of places, but you’ll be okay!”
Oval and Dash shared a look, sighed, and focused on shrinking themselves down. The first ten feet were easy, but after that it got harder and harder to make themselves smaller. After twenty feet, they were running up against “the wall,” finding it difficult to shrink any further - but they fought through it, and they shot down to twelve feet.

But just like last time, all that size couldn’t be completely suppressed. Oval spend a fraction of a second at his normal proportions, and then his body swelled with muscle from head to toe. And his cock exploded in size, growing back to four feet long. His clothes should have shredded themselves again - but thanks to the enchantment that Princess Twilight had instructed Rarity in casting, they changed to fit him perfectly. His shirt widened, becoming attractively snug on his muscular arms… and his jeans developed a generous bulge in the front. They didn’t hide his coiled-up cock, but at least they covered it.

And Dash, going for her minimum size for the first time, underwent a slightly different change. Her muscles, already impressively toned, didn’t get any bigger; responding to subconscious desires, the growth shot into her curves - her ass swelled into a bubble that stuck out three feet behind her, and her tits ballooned to nearly the same size. And her clothes kept up with her growth, stretching to embrace her new assets.

“Well, hey!” said Twilight. “You look great!”

“Well yeah, obviously we look great,” said Rainbow Dash. “We’ve looked great from day one! But how are we supposed to go to school like this?”

“Huh, usually I’m the self-conscious one,” said Oval Office.

“It’s not that,” said Dash. “Gonna have a hard time squeezing these boobs through a door… not to mention this thing.” She slapped her ass, and it wobbled from the impact.

Twilight approached Dash’s backside, raised her arms, and placed them on either side of her rump. “I think you can juuust make it,” she said. “As long as your butt is soft enough…” She squeezed Dash’s giant cheeks, compressing the bubble as much as she could. “Yeah, this seems good!”

“You’re not gonna squeeze my boyfriend’s crotch like that, are you?” asked Dash, looking at Twilight over her shoulder.

“No, that would be counterproductive,” said Twilight. “The softer his penis is, the easier it’s going to be to squeeze it through a door.”

Oval shrugged. “All right, let’s give it a try.” He got on his hands and knees, smiling apologetically at the other students - the normal-sized ones - who were trying to make their way into the school. They parted, giving him plenty of room, and he made his way - crawling, sideways - through the middle set of double doors. His dick got snagged on the edge of the doorframe, and he wriggled through, crouching on the other side of the door. “All right, you try,” he called out to Dash.

“Ugh, this is not gonna be easy,” groaned Dash. She crouched and turned her body, working her shoulders through the doorway. Her progress halted abruptly when her boobs hit the doorframe, and she grabbed her tits, squeezing them tight against her chest as she wiggled through.

“You need any help?” asked Oval.

“Oval, you know I love it when you grab my boobs,” grunted Dash. “But I think this is gonna go better if I don’t have anyone getting in my way.” She got her tits through, only to get her ass stuck in the same way.

“Want me to push?” yelled Twilight from outside.

Dash scowled and wriggled her body. “No! I’m… fine.” She flexed her glutes, trying to shift her butt around. “Dammit, being huge is supposed to be fun,” she grumbled. “Stupid door’s making me feel bad about having a giant butt…”

She worked herself through the door and slumped against the lockers, right next to Oval Office. “Okay, now you can grab my tits,” she said, leaning her body against Oval.

“After school, maybe?” said Oval.

“Ugh, that’s a long time to wait,” said Dash. “At least we have a lot of classes together.” She reached her arm around him and gave his butt a little squeeze. “See you in second period,” she said. “I’m gonna crawl off to my ‘math for airheads’ class. Hopefully we won’t be talking about any really big numbers, or I might start to think about growing…”

Oval gave her a kiss on the cheek, and Dash giggled happily. “See you later, baby,” he said, and set off towards his first-period class.

Class was… a little awkward. The students of CHS were more accepting of strangeness than the average high school students - having already lived through magic demons and mind-controlling sirens, they were pretty willing to accept a couple of giants. And if it had just been their size, it might not have been all that awkward. But they also had distractingly large assets - Oval had his enormous crotch bulge, and Dash had her colossal boobs and gigantic ass.

Spending the first period apart, Oval and Dash were each the solitary focal points of their classmates’ disbelieving stares. Oval tried to be his usual self - casual, friendly - but he was a 12-foot-tall, hulking giant leaning against the back wall of the classroom, and it seemed like there was always at least one pairs of eyes taking a sidelong glance at the unreal spectacle that was his body. Oval couldn’t gauge everyone’s reaction, but he noticed a few girls biting their lips as they eyed up his bulge. A four-foot cock was too much for any of them… but they sure looked like they wanted a closer look.

Dash had it even worse. The boys in her class weren’t particularly good at hiding their interest, and she spent most of the class scowling at gawking guys. This wasn’t any fun - not only was Oval not there with her, she just didn’t feel powerful like this. When she was out on the town, stomping around, waving her tits in every direction, she felt like a goddess… but here, cooped up in a classroom that barely accommodated her huge, beautiful body, being big just felt like an inconvenience.

So it was a relief when Oval and Dash reunited for second period. They were still getting lots of stares - maybe more, now that the students were seeing both members of the giant couple. With a little imagination, anyone who saw them could easily imagine what it would be like to watch them fuck.

They both took a seat on the floor, leaning against the back wall of the classroom, leaning affectionately against one another. The history teacher probably should have told them to put some distance between themselves, and a flicker of doubt across his face suggested that he was considering it… but he found the giants a little too intimidating to confront.

“I missed you,” whispered Oval, during a lull in the lecture.

“Me too,” said Dash, wrapping an arm around Oval’s waist. “That’s the longest we’ve been apart for a pretty long time.”

Oval smiled. “And you haven’t gotten sick of me yet.”

“How could we ever get sick of each other?” asked Dash. “Every day we’ve spent together has been exciting, and we’re both…” She shot a glance toward the front of the class, where the teacher was starting up some kind of educational film. That seemed to be grabbing everyone’s attention - so she turned back to Oval with a grin. “We’re both constantly changing… getting better…”

Her breasts, already huge beyond reason, started to swell. She leaned more of her weight on his body, placing her growing tits in his lap… then she grabbed his arm and slapped his hand against her ass, letting him feel her growing cheeks.

“Uh, just how big are you planning of getting?” whispered Oval Office. “This could get to be… to much…”

“You’re one to talk,” said Dash. “I feel you growing too.” She shook her shoulders, making her tits bounce in Oval’s lap.

“Yeah, but… not on purpose… and not, like… magically…” He grunted uncomfortably as his stiffening cock uncoiled inside his pants. This could be a real problem - his jeans had grown big enough in the crotch that they could hold his four-foot cock, but if it stiffened… well, he didn’t know if his pants could deal with that.

“Well, I’ll stop growing if you stop growing,” teased Dash. She leaned her body forward, settling the full weight of her growing tits onto Oval’s crotch.

“Come on, Dash, eventually someone’s gonna turn around and see us,” Oval grunted, shifting his hips to try and keep his cock contained. “If we don’t… mmh… oh shit-”

His dick, fighting to grow to full hardness, strained against the denim of his jeans - and his boner punched through the material, tearing apart the crotch. The sound of it filled the classroom, easily overpowering the volume of the educational film. Everyone in class turned to look - and although Dash’s boobs were covering his entire crotch, and thankfully concealing his dick, it was pretty obvious that something had happened.

“Uh, I gotta go,” said Oval. “Bathroom!” He rolled over, covering his crotch, trying to keep his dick out of anyone’s line of sight. Fortunately he was close to the exit - and getting his cock through the doorway was actually easier now that it was erect, rather than coiled up in his jeans.

But Dash, who followed him to the door, didn’t have as easy of a time. With her body turned sideways, her head and shoulders got through just fine, but her tits - their circumference a couple feet bigger than the last time she’d gone through a door - took up the entire door frame, wedging her tight. “Fuck!” she swore, wriggling helplessly. She reached her arms out and looked pleadingly at Oval. “Okay, this time I do need help!”

“Okay,” said Oval, taking both of her hands. “Can you shrink your boobs down? You should be able to get them down to where they were before…”

“I’m trying,” said Dash, “But it’s hard to focus… I’m pretty horny right now, and it doesn’t help that my boobs are getting squeezed… Just pull, dude, just get me through the door and we’ll sort it out later.”

Oval pulled, and Rainbow Dash grunted, biting her lip as a hot blush bloomed on her face. “Fuck… so weird… how good this feels…” she grunted. She turned to meet Oval’s gaze, her eyes flickering towards his musclebound arms. “Damn, dude, you’re strong,” she said. “Tug me out of here so I can feel up your body.” Oval summoned up the immense strength in his arms and pulled, and Dash’s tits squeezed through the door - but her body got stuck again when her ass wedged in the doorframe.

“Damn it,” muttered Dash. “Okay, one more pull, get my giant ass through the…” her face twisted in confusion, and she looked backwards. “Aw dammit, I feel hands on my butt. They’re pushing. They’re trying to help… Come on, help me out here.”

Oval braced himself, preparing to pull Dash’s ass through. “What’s wrong?” he teased. “You don’t like having a lot of hands on your ass?”

“I don’t like being helpless,” said Dash. “Dammit, I could just grow to a hundred feet tall and bust out of this school…”

“No, I got you,” said Oval. He pulled, and yanked Rainbow Dash free - then his hands immediately shot to his crotch, covering his naked dick. “Okay, what’s the fastest way out of here?” he asked. “I’ve gotta ditch and get a new pair of pants, and you’ve gotta… calm down until you can shrink your boobs and your ass.”

“Nah, if you’re ditching, I’m ditching,” said Dash. “Let’s sneak out through the gym, okay?”

The two of them crawled together through the halls - which were mostly unoccupied, since class was still in session. The entryway to the gym was a generous set of double doors, so they made it in without a problem - and they could finally stand up straight, thanks to the high ceilings. They stretched their arms over their heads, groaning with relief. “Ah, feels good,” said Oval. “All right, I guess I’ll just head back to Applejack’s farm until someone can enchant a new pair of pants for me.”

“Yeah, these ones are busted,” said Dash. She took hold of the waistband of the jeans and yanked on them, tearing the seams until the whole garment fell to the floor in two pieces. “Might as well just go naked, right?”

“Dash!” yelped Oval. “Great, now I’m naked,” he grumbled.

“Hell yeah it’s great!” said Dash, smacking his perfect blue butt. “I want you naked as much as possible. Besides, weren’t those pants uncomfortable? You had to keep your dick caged up like that… wearing skirts is much more freeing!” She turned around and shook her ass - only about a quarter of which was covered by her plaid skirt. Her pink panties were holding on, covering her huge sky-blue ass, but they were straining, stretched thin. “See? No matter how big my butt gets, my skirt doesn’t get in the way.”

Oval couldn’t help but stare at Rainbow Dash’s wiggling ass. “So are you saying I should wear a kilt, or - woah!” Dash suddenly enlarged her ass, and her cheeks closed the distance between her body and Oval’s cock. Now his hard cock was wedged into her crack - or at least, as far inside as it could get while she was still wearing panties. “Dash, if your butt gets any bigger, you’re gonna have a hard time getting out of the gym.”

“Well, I’m not thinking about getting out of the gym right now,” said Dash, grinding her butt against his cock. “I’m thinking about getting my butt big… and then getting my big butt fucked.” Her ass swelled again, so that it protruded six feet out from her backside, and she fell to her knees. “Oh man, I got a big, heavy butt…” she moaned. “You wanna come over here and fill it?”

“I don’t think my dick’s long enough to get all the way in,” said Oval. His cock was still stiff, four feet long, dripping precum, starting to throb as Dash’s ass rubbed against it.

“So make it bigger,” Dash said. “Just make that cock long and thick enough to fuck this big… round… butt!” She grew her butt bigger, big enough that her enchanted panties finally gave out and tore themselves to shreds. Now that her asscrack was unguarded, her grinding motions started to work his cock deeper into her butt.

“Fuck,” gasped Oval. “All right, let’s do this.” He enlarged his cock, and it penetrated deeper into Rainbow Dash’s giant ass, parting her big round cheeks until it arrived at her tight, puckered asshole. “All right, you want it?”

“Yeah I want it,” said Dash. “Oh fuck, I can already feel how big you are, Oval… stick it in me, grow big, fuck me deep…”

Oval enlarged his cock by another foot, simultaneously thrusting his hips. He penetrated Dash’s asshole, and she cried out in pleasure, groping at her giant tits as Oval thrust deeper. “Fuck yes, dude,” she groaned. “I love it when you go deep, baby. Let me give you… even more ass to fuck.” She made her ass grow bigger, so big that Oval was halfway inside it, his head barely above the top of its 10-foot circumference. He grew his cock again, keeping himself inside her - and it grew in girth at the same time, now two feet thick as it pounded Dash’s ass.

“Ohhh my gawwd…” groaned Dash. “Oval, you’re huge, you’re stretching me so good, you’re so deep in my huge round butt… I could keep right on growing… force you to make your cock bigger and bigger…”

“Come on, don’t make me work,” said Oval. “I don’t wanna outgrow the gym or crush the school… I just… really need to cum.” He thrust with all the strength in his hips - which, thanks to his giant muscles, was a lot. Dash let out a wordless, broken moan when the impact hit her - and then another, and another, as Oval thrust again and again. “Just let me cum, Dash… I know I can make you cum too…” He made himself a little bigger, penetrating deeper and stretching her ass wider. “Are you close, Rainbow Dash?” he grunted. “Is my big dick about to make you cum?”

“Oh fuck, yes, yes,” gasped Dash. “Ride my ass, pound me stupid, make me screeeam… Oh fuck, Oval, Oval!” Her whole huge body shook as she came, and Oval Office was surrounded on both sides by walls of wobbling blue butt-flesh. “Oval, you gotta cum for me, fill up my fuckin’ ass, flood me with cum…”

“Yeah, I’m close,” Oval grunted, digging his fingers into the flesh of Dash’s cheeks. “Oh shit, this is gonna be huge… gonna shoot a big hot load outta my giant cock… oh fuck, I hope you’re ready baby, it’s so much fuckin’ cum-”

Oval Office’s whole body jerked as the first spurt of cum burst from his cock, rocketing from his tip and splattering against the inside of Dash’s ass. He flailed as his cock pumped again and again, barely holding onto Dash’s ass as climax rocked his body. Groaning, he fell backwards, and his cock popped out of her butthole, splattering her asscrack with thick sticky spunk. By the time he was done coming, Rainbow Dash’s ass was dripping with spunk, sitting in a thick white puddle.

“Fuck,” gasped Rainbow Dash. “Going to school was almost worth it… just for the chance to ditch class and get my ass fucked in the gym. So what now?”

“Well, I’m still pantsless,” said Oval, leaning his body against Dash’s left asscheek. “Which was the original problem. So I guess I’m going back to Applejack’s farm.”

“You guess you’re going there?” teased Dash. “You don’t sound that excited, dude. Are you open to suggestions? Because what I wanna do is go some wide-open place and get big.”

“I had a feeling that’s what you were going to say,” laughed Oval.

“Well yeah, that’s what I’m into lately,” said Dash. “But think about how good it’ll be! We’re in control now. Don’t you wanna know how big we can get? I wanna grow with you, Oval. I wanna get big, and watch you get big, until we can’t keep our hands off each other…”

Oval smiled and shook his head. “At some point in this relationship,” he said, “I’m gonna have to figure out how to say no to you.” He pushed off of Rainbow Dash’s ass and shrunk his seven-foot cock to a sensible four feet. “All right, let’s go for a walk,” he said. “But you’re gonna need to shrink this huge ass back down or we’re not getting out of this gym.” He gave her butt a smack, and she giggled happily.

Outside the gym, back to more sensible proportions, Oval scanned the horizon. “So where are you thinking of-”

Oval felt fingers gripping his body, and suddenly he was rising into the sky. “Too slow, dude!” said Dash. “I’m already huge. I’ll figure out where we’re going, all right?” Dash - about a hundred feet tall at this point - tucked Oval into her spacious cleavage. Her breasts were still massively, wonderfully disproportional, so big that they hung down to her belly button despite being perfectly firm. “Hang on, babe!”

Dash took off running, instantly picking up a superhuman burst of speed - partly because she was a hundred feet tall, partly because of her enhanced body, but mostly because she was Rainbow Dash. Her breasts, in defiance of the laws of physics, stayed almost completely stable as she ran, barely bouncing at all… and she ran with absolute precision, setting her feet down on empty patches of grass, unoccupied sections of road, and mostly empty sections of backyard. As she sprinted through the suburbs, a few fences got crushed underfoot, as well as a couple of unoccupied swingsets and porches, but she mostly kept the destruction to a minimum.

“What do you think, Oval?” asked Rainbow Dash, not seeming to be even slightly out of breath as she ran. “How about we chill by the mountains… and outgrow them?”

“Sounds like fun,” said Oval.

“I’ll get us there in no time,” boasted Dash. “Actually, I can get us there even faster if I lengthen my stride a little…” She grew, giving herself about fifty more feet of height, and soon she was striding farther and leaving bigger craters in the dirt. The distant mountains grew closer with each second - within minutes, Dash and Oval were well outside of town, stomping through the woods, flattening trees. And then they were at the foot of the mountain range, overlooking a crystal blue lake fed by a mountain stream.

“Ahh, beautiful,” said Rainbow Dash. “Much better than a day at school.” She lifted Oval from her cleavage and brought him to her lips for a kiss, pressing her lips against everything from his face down to his balls. “Wanna go for a swim?”

“Huh?” said Oval - but he soon got the point, when Dash lowered him to the level of her waist and dropped him, letting him fall right into the calm blue lake. It was a hell of a drop - some seventy feet or so - but his musclebound body was tough enough to take it. He plunged deep, then swam back to the surface, only to see the cloudless sky falling towards him -

No, it wasn’t the sky - it was just Rainbow Dash’s sky-blue bottom, falling right towards him. She was doing a cannonball into a lake that was barely big enough for her body. There was no time to swim out of the way… but it looked like her asscrack was going to come down right on top of him, so he’d probably be all right.

Rainbow Dash landed with a splash that probably drained half the lake’s water. Parting her legs, she looked down into what remained of the lake, searching for any sign of Oval Office. “Dude?” she called out. “I didn’t crush ya, did I?”

Suddenly Dash felt something pushing upwards on her butt. Something much bigger than a twelve-foot-tall beefcake. “Ooh, are you growing?” asked Dash. “Get real big for me, babe, I wanna see you grow into a big strong man…”

And Oval didn’t disappoint. He grew bigger and bigger, his thick legs and long cock swelling as his body rose from the lake’s bottom. Soon he was just as big as Rainbow Dash, but he didn’t stop there - with Dash seated on his lap, he made himself bigger - soon Dash’s head only came up to his pecs, then she was leaning her head on his washboard abs, and then - as he stood from the lake, water dripping by the gallon from his flawless glutes - she was happily straddling the base of his cock.

“Oh, now this is what I’m talkin’ about!” said Dash, bouncing her big round butt on the shaft of Oval Office’s stiff cock. “Damn, dude, even your cock is buff! My ass alone weighs tons, and you’re holding me up no problem!”

Oval was a good five hundred feet tall now, big enough that his cock could support the full weight of a hundred-and-fifty-foot-tall Rainbow Dash. “You like?” he asked. “I was getting tired of being the smaller giant, so I decided to outdo you.”

“Well don’t stop now!” said Rainbow Dash, grinding her butt against his cock. “I wanna ride a big fat cock! I wanna see how big my boy can get!”

“Anything for you, baby,” said Oval, and he began to grow again. His cock got so thick that Dash was having a hard time straddling it - so she wrapped her arms and legs around his shaft as best she could and started climbing. Clutching the veins of Oval’s cock, Dash climbed upward, hefting her weight toward the tip of the growing shaft - and with her trademark speed, she arrived at the mushroom head of Oval Office’s big blue cock. She parked her butt on his tip, letting warm precum spurt up against her asscrack.

“Not bad, dude!” she laughed. “You like being huge, huh? How about you bring me in for a kiss, big boy?”

Oval wrapped his arms around his cock, hugging it against his body. It was still disproportionately large - and it was exactly long enough that Rainbow Dash, seated on his tip, was lifted right to his lips when his dick stood straight up. She planted a kiss on his lower lip, taking a moment to relish her boyfriend’s immense size… and then she started to grow, determined to become a full-sized partner for her man.

Once Oval noticed Dash was growing, he put his hands under her butt, cradling her oversized ass. As her mass and her height increased, his hands dipped lower, keeping her mouth level with his and maintaining contact between their lips. Once she was big enough, Oval extended his tongue into her mouth, penetrating her lips, filling her mouth with a tongue that was many times bigger than hers. His fingers - big, long, and thick - crept into her pussy, parting her dripping lips and exploring her depths as she grew.

And before too long, Rainbow Dash felt her feet touching the water of the lake. She was nearly as big as Oval now, about a thousand feet tall, and the knowledge of her size was deliriously arousing. She planted her feet on the lakebed and leaned into Oval, wrestling with his tongue, pressing her tits into his chest, and grinding her slick pussy against his shaft. “Let’s do it,” she whispered, pulling back from the kiss. “Let’s get big.”

She let herself fall backwards, wrapping her arms around Oval Office to drag him down with her. Her big ass landed on the mountainside, damming the stream the fed the lake and flattening the trees that dotted the ground. Oval landed atop her, his cock wedged between her tits and dripping precum into her cleavage. She grabbed his cock by the head, navigated it downward, and put its tip against her pussy lips. “Let’s grow, baby,” she moaned as he entered her.

“Yeah,” whispered Oval, sliding himself deep inside her - and simultaneously growing his whole body, lengthening and thickening his cock inside her pussy. “Yeah, I wanna grow with you Dash, I wanna get big… Make those boobs grow, and I’ll fill your pussy with a long, hard cock…”

“Sounds like a good deal,” said Dash. She grew right along with Oval, expanding her tits and ass a little faster than the rest of her body. “Just show me how big you can get… and how big a load you can shoot into my hot, tight cunt…”

Rainbow Dash and Oval Office grew in perfect sync, their bodies intertwined, as Oval fucked Dash against the mountainside. The two giants heard a progressively louder cracking sound as they grew bigger - a sound which they eventually realized was shattering stone. Oval’s thrusting hips were hammering Rainbow Dash’s ass into the mountainside, pounding a deepening rift into the stone, slowly breaking the mountain apart.

“We’re so big,” groaned Dash. “You and me could wreck everything… flatten every mountain, smash every tiny little city…” She groped her giant tits, throwing back her head and tossing her long rainbow-hued hair. “Oh, Oval, I wanna see you swing that cock and knock down skyscrapers… I want you to flex your muscles and crack the fuckin’ planet…”

Oval Office was already putting cracks in the earth, sending long, jagged cracks through the mountain range that Rainbow Dash was leaning against. “Whatever you want,” groaned Oval. “Just as long as you grow with me...” Now a couple thousand feet tall, Oval thrust his hips - and the mountain beneath Rainbow Dash’s butt shattered into gravel, and she fell flat onto the earth.

“Oh fuck,” groaned Dash. “Fuck me into the fuckin’ ground, Oval… you’re a fuckin’ god, babe, your cock is so fuckin’ powerful… come on and fill me up, blow your load, shoot a lake of cum into my hot pussy…”

Oval held Rainbow Dash tight, and together they grew, overtaking a mile in height. Oval came, and Rainbow Dash got the lake of cum she’d been begging for; Oval’s cock, more than a thousand feet long, pumped a flood of spunk into her pussy. The rushing fluid, pummeling the walls of Dash’s pussy, triggered a climax in the giantess’ colossal cunt. Her womanhood pounded with orgasm, tensing with enough strength to bend steel, and she cried out, pounding the earth with her fists and kicking her legs. Oval Office panted and whimpered, shooting whole lakes of spunk into Dash’s pussy.

Oval and Dash collapsed onto the cracked earth, panting and sweating, embracing one another, lost in the afterglow and the ecstacy of growth. Even after growing past a mile tall, they both felt that they could go further… but for the moment, they were happy to lay in each others’ arms, casting a long shadow over the mountain range.
