This story is dedicated to the wonderful Crimson Mage for being a spectacular friend to me. Thank you for all you do every day!

Nikki the orca belongs to Crimson.

Mary the dragon belongs to me.

The Beefcake Recipe, by DragonMasterX.

"Three... four... five..." Nikki mentally counted her reps. Hanging from the pull up bar, her chest heaved with every energetic pull. Her finned tail rigidly swayed in mid-air with every finished repetition. To avoid touching the ground, her long legs were pulled back and arched to the point her feet could almost touch the back of her own thighs. She could feel the effort her arm muscles were making once her breath became labored. Maintaining form was turning difficult, her legs beginning to sag and bend downwards again.

Nikki had chosen to work on her upper body strength that day. A dozen pull ups had been her record last time. Little by little she was getting better, but she was nowhere near where she wanted to be. Her reflection showed her the start of marked abdominal muscles and she could appreciate the tonality of her biceps starting to show every time she pulled herself above the bar. But her stamina was nowhere near developed enough. The spirit was there, but thirty-five years of being lazy did not come without their toll.

"Tennnnnn...!" Sweat dripped down her forehead, making her clench her right eye shut to avoid the bead going in. She ended half-way clinging to the bar, her heels below level with her knees now. A pant of exhaustion left the orca's maw before she tensed up and forced herself to finish the tenth pull up with proper form. "God- fuck, damnit...!" she clenched her fangs, having trouble keeping all that intensity inside. Summoning all of her strength, she completed one more pull up before finally her arms gave and she ended hanging limply from the bar. "Eleven..." she sadly concluded in her mind, tilting her head back 'til her eyes were completely obscured by her blonde bangs.

"How did I do worse this time?!" she cried out loud at the same time as she stomped her feet down on the wooden floor. The nearby gym patrons turned to look at the frustrated killer whale. Nikki was just over six-foot-tall thanks to her predatory cetacean heritage and she'd always lucked out with genetics.

Her body was a perfect hourglass, voluminous chest pushing out her sports bra to the point the straps crisscrossing her back looked almost painted over her shiny obsidian skin. Thick legs with even thicker thighs were in constant friction with one another, except now that Nikki was standing with her feet planted as far away from each other as she could. She was bent over, hands on her knees, her large butt sticking out in her spandex shorts and her enormous chest swinging beneath her. She was panting; although the concerned people seemed to be paying more attention to the blonde's curves than her state.

"Hey, don't be so harsh on yourself, babe," a voice came from behind Nikki as she gulped precious air, "I can give some pointers to a newbie!"

Nikki practically snapped to attention, turning herself around and standing upright. The sudden move sent her oversized rack wobbling, eliciting a grin from her interlocutor. It was a red wolf with a body seemingly sculpted by an artist. Bulging deltoids on wide shoulders, thick arms with more-than-handful biceps; although he seemed lacking in the lower body. His square jaw and fangs poking out through that toothy grin lent him a brutish, well-meaning, although ultimately perverse expression. She shot her gaze up at the taller male who had no less than seven inches on her. She cast an angry glare at him. "Fuck off, dude. Didn't ask for no help," Nikki said, using the back of her hand to wipe some saliva off her lips.

"No need to be rude. Just trying to help out!" the wolf insisted, putting a paw down on Nikki's shoulder. "Here, let me just..." he got cut off as she brushed him off, knocking his hand away before shouldering him out of the way. Or she tried to at least, when the lupine's grip returned harder than ever.

"You're asking to get hurt right now, man. It's not a good day to play the testosterone-heavy douchebag with me," Nikki growled, not looking at all pleased with the bigger wolf. This wasn't the first time she'd gotten unwanted advances at the gym; but she wasn't there to hook up with anybody. All Nikki wanted was to bulk up and get rid of the fat in her body. Unfortunately for her, she was top-heavy enough to bring interlopers looking for easy lays. "Just fucking go."

"Jeez, let a guy down easy at least, won'tcha?" the wolf laughed, "Look, you're looking exhausted 'cause you're going about it all wrong. When training your upper body all you gotta do is..."

The blonde was about to lose it. Her hands were starting to ball into fists, red color starting to tint her black and white cheeks. Nikki was about to punch that smart guy. But before she could even let loose, she saw him fly into a wall. Her eyes widened as, in replacement of the red wolf's imposing pectorals, Nikki was now being loomed on by somebody even taller. She saw a perfect, smooth six-pack and quietly glanced up only to have her vision obstructed by a chest just as enormous as her own on an even taller body.

"Nikkiiiiiiiiiii!" a shrill and feminine, yet very familiar voice made Nikki take a quiet couple of steps backwards. With a cursory glance she saw the toned arm of that amazon stretch out in the direction of the red wolf embedded in the wall. "Oh whoops. Sorry about that, guy!" the incredibly tall girl said, "I only meant a little shove is all!"

"Jeez, Mary. He was being jerk but he's lucky if he's got all of his ribs intact!" Nikki exclaimed, huffing as she was scooped off the floor and hugged by the towering dragoness in front of her. "Oof! Careful! I'm all sweaty and shit...!"

"Sweat is what we're at the gym for," Mary giggled, snuggling her smaller friend in a bear hug that caused the orca's face to nearly vanish in the dragoness' deep cleavage. Like Nikki, Mary was wearing a sports bra and workout shorts combo which brought attention to her prodigious rack. "I'm sorry I'm late to spot you! I was running late after classes, and then one of the ovens caught fire because one of the interns wasn't paying attention and then I had to make all those deliveries and..."

"Mmmpph...!" struggling for precious air was all that was in Nikki's mind. Mary's hug felt nice and soft, but Nikki already had been agitated and being oxygen deprived by giant dragon breasts wasn't doing her lungs any favors. "Bwah! Shit dude, you could kill somebody with these tits," the blonde panted as she finally managed to pull her head back out. "Do you ever hold back?" she cocked an eyebrow up and pointed back at the silent red wolf still coming to terms with having become part of the wall in the back.

The dragoness grinned, "My bad! Was he a friend? Ooh! Was he a..."

"STOP!" Nikki yelled, "Stop right there, don't." She inhaled deeply, patting Mary on her solid yet just toned biceps so that Mary would set her back down. "Thinking about it, you probably saved that guy from what I was about to do to him. Anyway, you're cool," the orca pulled her arms back and stretched a little, "Was just doing some pull ups. Working on upper body strength, like you said."

"Awesome!" Mary nodded, "You look super winded though. Have you been at it for long?"

"...just finished, actually," folding her arms under her impressive bust after tossing her ponytail back, Nikki huffed. "...even..."

"Huh?" Mary poked her cheek with a curious frown. She hadn't heard properly.

"Just did eleven..."

"That's great!" Mary clapped her claws together.

"What? No, that's shit. I managed twelve last Friday, Mary."

"Well, did you do your warm up exercises?"

Before Nikki could reply, she thought about what Mary was saying and bit her tongue. "Fuck. I always fucking forget," she mumbled, shaking her head.

"You're gonna end up hurting yourself, silly. Got to help your body get used to all that effort you're making!" The dragoness explained, "Buuuuut it's my fault for being late. I did say I was going to help you! So, sorry about that."

"You're the only one I know who apologizes so easily," Nikki cracked an amused smile at Mary, "Well, you're here now. Help me warm up like I should've?"

"You got it! Here, let's go get ourselves a couple of mats. I'm gonna work out with ya!"

Over the next forty minutes, Nikki saw the incredible grace and amazing body dominion Mary displayed which, next to a newbie like her, made the dragoness look like some goddess of the gym. Nikki was no fool and knew Mary was holding back to let her follow the routine, even helping by correcting her when necessary. It made her feel like a burden when she knew her friend could be completing twice as much work if she wasn't stopping to help tilt Nikki in the right direction or help her angle her limbs in ways that wouldn't harm her joints.

"Jeez, Mary. Are those 250lbs. dumbbells?" the orca stopped stretching to watch the amazon curling loaded weights that would've broken the arms of any beefcake whales she'd seen at the gym. "You're too fucking strong."

"It's easier because of my size, but I've been at this for two years, y'know! It takes time to build strong muscle!" Mary giggled. Alternating between arms, she curled the heavy duty equipment as if they were weightless.

"Two years... you told me you're 18 right? Still finishing high-school? What the hell...?" Nikki wasn't struggling with the math as much as she was amazed by the incredible results a girl half her age had managed. While the dragoness wasn't bulky at a glance, the attractive muscle tonality of her biceps could be appreciated with every flex of her arms. Mouth-watering tautness over those smooth-scaled blue muscles was enough to bring attention away from those overly developed mounds at the young dragoness' chest. "You dragons are big fuckers."

"I don't hear you stretchiiiing!" Mary cut in in a sing-song voice, looking down at Nikki with a sharp fang escaping just under her smiling maw.

"Going, going. Bitch, you're demanding!" the orca huffed, leaning forwards and smooshing the top side of her right leg with her chest as she did her best to grasp her foot with her feet. Because of the resistance provided by her bosom, she could barely touch the tip of her feet. "Shit my legs are burning...!"

"Then it's working! Keep at it, Nikki! Those leg pulleys didn't feel like much but if you don't stretch now you'll feel super sore tomorrow! And the day after. And then you'll start wanting to skip leg-day!"

When Nikki first signed up at the gym six weeks ago, all that had been in her mind was lifting heavy weights with her arms and ending up like a bodybuilder in just a month. She had never once stopped to ponder all the in-between work necessary to sculpt her body the way she wanted it to look like. With Mary constantly putting most, if not all the ripped bodybuilders in the gym to shame with her excessive physical strength, the orca's envy was at an all-time high. And yet, by natural aloofness or kindness, Nikki understood Mary wasn't trying to put anybody down. It made even a bitch like her want to stay and listen.

"Right, all stretched up. What's next?" a wobbly Nikki brought herself up to her feet. Her legs were shaking like jell-o.

Setting her weights down, Mary reached over to the nearby bench to throw Nikki a towel. She grabbed one for herself and used it to soak the sweat off her neck. The smooth scales were looking extra glossy with that pretty sheen. "I think that's good for today!"

"Hey, I'm not done. I wanna do..." Nikki paused, panting a little, her bravado breaking for the necessary instant for Mary to intercept.

"No no. You've forced yourself to your limit enough. Even I'm bushed! Let's just put our things back where they were and go take a shower, okay, ballenita?"

Huffing, Nikki closed her eyes in defeat. She had to admit she'd been wanting a shower for the past hour of intense workout. In the end, she shrugged and simply nodded, keeping her chin up in an effort to hide her weakness. "Whatever you say, boss. Actually, what did you say... ballenita?"

"Lil' whale!" Mary clarified with a grin, reaching around to give Nikki's backside a swift spank.

"Right, your English's so good I usually forget you're South American... Ahhn...!" Nikki stood up straighter than usual, caught by surprise by that smack. The orca's massive behind wobbled in kind, enough to draw the attention of those nearby. Nikki had to put her hands on her gluts to stop them from jiggling. With an embarrassed blush she snapped at the giggling Latina, "Hold back a little, you dragon bitch! That hurts y'know?!"

"Aww, sorry. I was trying to encourage you!" Mary playfully said.

"You're gonna slap my fat ass off with encouragement like that!" The pissed off whale reached around to repay Mary's spanking slap with one of her own. Without holding back, Nikki found out the hard way that the latina's big, muscular butt was firm enough to not only resist her pitiful excuse for a smack but also return the impact. "Sonuva...! Even your ass has muscles," Nikki winced, holding her briefly aching fingers.

"Mmm, I feel pretty encouraged myself now!" the dragoness joked, getting a sneer from Nikki. Leaning down, Mary's chest practically jutted out at Nikki as she loomed over the smaller killer whale, "I know, I know. But you have a pretty spankable behind. I'll make it up to you though. How's a massage at the shower sound?"

"Won't you just squeeze my shoulders to dust?" Nikki's sarcasm was cutting, but Mary was still beaming.

"I promise to hold back as much as possible. Here, I'll put away your stuff too. You go on ahead, alright?"

The way in which Mary piled on mats and equipment over one arm and shoulder was almost like watching a cartoon. Nikki couldn't believe how ludicrously dragons could get. Was the gap between species that big? No. She was convinced she'd seen scrawny dragons significantly older than Mary struggle with weights even a gym newbie like Nikki could lift with ease. "Maybe I really do have to do things like she says..." the orca muttered to herself as she walked over to the lockers to get her things.

Nikki thought about how a month ago she couldn't even do a single pull up, and now she was consistently getting better. "I wanna get big and buff," was the goal constantly repeating itself in her head like a mantra. Inside the women's locker room, Nikki stared at her nude figure in the mirror of her personal locker. She truly was a curvaceous, thick woman. The start of marked abdominal muscles could easily be noticed on her mid-section whenever she inhaled deeply, and if she tensed up the right way she could make her biceps pop out when she curled her arms. "Is it because of my whale blubber...? Am I really not going to get taut, ever...?" she frowned, striking pose after pose to check herself out.

The major amount of tautness in her figure, of course, was her surprisingly perky breasts whose head-surpassing size belied their firmness. In spite of Nikki considering herself fat, the great bubbly shape of her behind was also without flaw, jiggling perkily with every sway of her wide hips. "Screw it, I am a hot bitch." Nikki thought as she cocked her hips up and rested a hand on them, her ego reaffirmed in an instant. Any seriousness in her face, however, disappeared when her head vanished under several dozen pounds of marshmallowy-white, soft boob flesh coming from above.

"Hiiiiii...!" Mary's irritably sweet voice was muffled, but Nikki could just picture her grinning face. It wasn't the first time she'd greeted her with a boobhat.

"Get your fat moo tanks off me, Mary."

"Aw, don't be so grumpy, Nikki," the dragoness stepped back, sliding her chest off Nikki. When the orca saw them in her reflection, her ego was lightly bruised. She knew it was only because of their height difference, but while tall dragoness' breasts were just about the size of their owner's head, each, they absolutely dwarfed Nikki's. The orca was convinced she was more stacked, but the clear difference in scale put her on the losing side. "You had a great work-out day. Let's relax now!"

Looking at that cheerful dragoness, it was easy to tell she was a young, blossomed out beauty. Putting it into perspective, Nikki realized they weren't very different. She had also developed her killer-looks early in her life, and had maintained them even into her 30s without major effort.

There were two differences between her and Mary. One was that the dragon's curves were slightly smaller than Nikki's in proportion to the rest of her. And yet she couldn't deny how disproportionately big the dragoness' tits were on her sturdy, Amazonian frame. The more obvious difference was in their builds. Toned musculature, defined six-pack, a thigh gap she could see the underside of Mary's gluts through... It all pissed her off. She wanted that for herself!

Tossing her long, snow-white hair over her shoulders, Mary rested her knuckles on her waist, puffing her left cheek out while tapping her foot on the floor. "Ready for that shower?"

Finally letting her blonde hair down, Nikki forgot about her envy for a moment with a simple mental phrase: "So the big titty Latina has the beef. I'll show her I can get there too!" And with that, Nikki finally smirked, "You owe me a massage."

"Woo! Yeah. I hated leaving you hanging for half hour! I'm gonna make it up to you now. You know, my fingers can work some magic with knots and stuff!" Mary clapped her claws in delight, skipping towards the showers. "Ooh! Looks like we got the place all to ourselves, amiga. Let's get wet!"

The choice of words made Nikki snort. "Just don't break all the bones in my body, dude. I don't wanna take any days off if I can help it, alright?" the orca joked, sauntering her deliciously curvy body into the showers with her bigger friend.

In a matter of minutes, the women's showers became steamy with only the pair of open shower heads above Mary and Nikki. Pretty indigo tiles on the walls, floor and ceiling became glossy with humidity. "Ahhh!" Mary moaned in delight as she pressed her elbows down against the sides of her ribcage, shivering to the sensation of hot water hitting her scaly body. "Nothing beats a hot shower after working out! Me encanta...!"

"You always crank the hot water all the way up," Nikki remarked, standing under a shower head skipping another; she didn't want to get scalded. Completely doused, the orca pulled her wet blonde hair behind her shoulders and stretched, making her immense chest bounce. Each of her alabaster breasts was adorned with dark pink areolae capped with firm looking nipples.

Mary did the same as Nikki, but she also pulled her bangs back since they were longer than Nikki's.

"I love it!" she soaped her claws up and began to scrub over her muscular arms, "Wanna try?"

"I'm pretty sure I'd burn my skin off if I took a shower that hot, Mary."

"Well," Mary paused, looking up in deep-thought for a second. She grinned towards Nikki, "I'm a fire dragon. Of course I like it a little hotter! But alriiiight. Let me cool it a little or else I'll just burn you with my touch when I massage you!"

"...you were going to try to massage me as is if I didn't chime in, weren't you?" Nikki narrowed her eyes into a deadpan expression, prompting Mary to dismissively wave with a claw and laugh.

"Don't be silly! I can regulate my body temperature. Both ways, in fact! I could burn hotter than this water in fact; turn it into steam before it even..."

"You'll blow the place up if you do that, dumbass!" Nikki interrupted.

"Oh right... pressure in an enclosed space... Whoops, hehe!"

"I swear it's like you've got your head in the clouds sometimes," Nikki rolled her eyes with a little laugh, "Must suck being so tall." She playfully jabbed.

"Hey! Don't hate me for being big and beautiful, shortstack!" Mary countered with a teasing giggle. The bulging, irate vein behind Nikki's head indicated she had taken a blow.

"Bitch, I'm six freaking feet tall. I'm not_that_ small!"

"Yes, yes. Sorry about that," Mary finished rinsing her long hair, gradually turning the knob on her shower off until the faucet had fully stopped. "Now show me your back," she smiled, cracking her knuckles loud enough to make Nikki take a step backwards.

"I'm not that small, but I'm definitely small to her," the orca thought with a gulp as Mary loomed over her. With a huff, she turned her head indignantly to the right and sassily put her hands on her hips. "Hmph, whatever," she said, starting to turn around, "This better be good."

"Wanna sit down for this?" Mary asked, "I'll have to kneel anyway, but it's going to take me a while. Might want to turn that off, too."

Without saying anything in response, Nikki turned the shower off. The two friends were left in silence in the steamy showers. The orca had nothing against sitting down and being comfortable, so she sat cross legged on the wet tiled floor, pulling her hair over her shoulders to the front.

"Oh!" Mary exclaimed as she went down on her knees. Her eyes were focused on Nikki's back, "Just look at your lats! They look super sturdy, Nikki!"

"Huh? What's that?" the orca had been interested in building muscle for the longest time, but it just occurred to her that she wasn't the most informed when it came to the nomenclatures. Biology lessons from high-school seemed hazy at best right now.

"These!" the dragoness' fingers pushed onto the sides of Nikki's lower back going up to the middle part to demonstrate. The orca let out an uncharacteristically girlish squeak in response. "Oh! Too hard?"

"N-no!" Nikki was blushing beet red, "It's just how it is with orca skin. Kind of sensitive. Anyway, you were saying those look good? They don't feel very different, to me."

"Well, that's probably because you're so used to the new strength you've been building over time that it doesn't seem like a big change. You have long hair like mine too, so I bet you don't get a good look at your back often, huh?"

"Ruh-right..." Nikki huffed a bit, starting to consider her efforts at the gym had actually been paying off in ways she hadn't noticed. She resolved to give herself a good, full body checkout later.

"But yes. There's a lot of muscle tone around here. Your back's really strong! You're making so much progress, Nikki. I'm so proud of you!" the dragoness praised, actually making Nikki's heart skip a beat. She wasn't used to hearing such sincerity in words of compliments; usually getting backhanded remarks from jealous women or outright sycophantic drooling from men. And yet even for all the teasing Mary had in that mouth of hers, the encouragement was something Nikki could feel.

"Oh... of course!" Nikki broke herself out of her embarrassed silence with an exclamation louder than she cared to admit. She followed up by tensing up in an attempt to bring those muscles Mary was talking about out while snooting skywards, "That's just the results of my efforts! Nothing less. Soon I'll be so strong I'll be able to suplex even you into the ground, so watch out!"

"Yeah! And that's why you deserve a revitalizing massage all over your strong body," Mary quickly rubbed her palms together before pressing all ten of her digits down on the orca's toned back. "Muscle building is more than just working out and eating right, y'know? You got to take care of your body's needs, like proper hydration levels and even occasional R&R!" One by one, she began pressing down her fingers, causing Nikki's bravado to melt into a low moan as Mary started teasing her inflamed muscles. "Now quit being so tense! You're gonna make me tear your new muscles apart instead of helping them relax, haha!"

"Shut it!" Nikki cut in with a growl but after a moment she managed to close her eyes and began to adjust her breathing. It didn't help her posture much when she felt Mary's claws work away on her back, making Nikki involuntarily lean forwards. "Just what is she doing back there... she's just touching my back, isn't she? Who knew massages could feel so good!"

The stoic façade Nikki was attempting to use was hard to keep up. She had to clench her fangs to stifle moans of pleasure, sinking her nails onto her knees in order to keep herself grounded. She didn't want to show any weakness.

Mary was having trouble around the upper part of her friend's back. She was so tense it was hard to make her relax! With a frown, the amazon started weighing her options. She had already asked Nikki to distend, but she had tensed up again for some reason. "Maybe I'm not doing a good enough job?" she thought, deciding to apply slightly more finger strength.

But Nikki only tensed up even more, her back muscles almost popping out at Mary! Between the additional resistance and strength adjustment, something had to give. "Hey, ballenita, are you enjoying yourself?" the dragoness asked, leaning forwards to a shaking Nikki.

"Thu-that was..." stuttering was all Nikki could manage. Her eyes were wide open, irritated and she could barely hang on from the pain of her squeezed back muscles. She had tensed up so much that Mary's pleasurable massaging had turned into painful pinching instead. "Great!" she finally forced herself to say with a shaky thumbs up and equally tortured grin.

Falling to silence for a moment, Mary let out a sigh, "You should've spoken up if it hurt. This was meant to help your back hurt less tomorrow, y'know!"

"Shut it! I'm fine," Nikki lied, putting a hand to her shoulder before circling her arm once demonstratively. And once was all she managed, instantly becoming paralyzed from the shooting pain in her back. "Ouch."

"There, see? You dummy!" Mary couldn't help but giggle, "Why do you have to be such a hardass, Nikkicakes? It's okay to say when you're having it rough!"

"Easy for you to say. You're fucking strong," Nikki complained, finally letting an exasperated sigh before allowing herself to collapse on her own back. For a moment, all she saw was Mary's abs and her immense chest marshmallows. Eventually, Mary leaned down to be face to face with Nikki; their snouts separated by mere inches. Nikki could hardly hide her blushing.

"How come you're so obsessed with strength, anyway? I don't think I ever asked," Mary curiously inquired.

"Hmph... it sucks needing help all the time, that's all. Plus, I don't like the way I look..." Nikki finally admitted. "I want big, beefy arms 'n shit. I don't wanna be a soft 'n squishy fatass anymore."

"Hmm, sure, you're pretty bottom heavy..."

"Watch it."

"...buuut you have a pretty slim waist! I think models would be jealous of you," Mary finished. "Why do you have to be beefy?"

"Because it looks badass! And I wanna look badass. I wanna be strong, and tall, and unstoppable like..." Nikki's words trailed of for a moment. Her cheeks puffed out and she averted her gaze from Mary.

"Ahh..." the dragoness put a finger to her own cheek in deep thought. Her eyes rolled up, considering something in her mind. "Well, nothing to it. I guess I can ask someone for a favor."

"Huh?" Nikki opened an eye, curiously aiming it at the looming dragoness who was already getting back up to her feet. When she offered Nikki a claw, she took it and also stood up. "What'cha mean?"

"You'll be happy if you can bulk up quicker, right?" Mary asked, getting a silent yet swift nod from her friend. "Well, leave it to me! I'll help you."

"Wait wait, is this about what I said? Shit," Nikki began to wave her hands together, "Look, forget about it. I appreciate the help but..."

"Just leave it to me, ballenita. I'll get you something that'll cheer you up and up!" Mary giggled.

With a huff, Nikki shut her eyes and tried calming down. She couldn't believe she had psychologically bared herself with Mary and made herself look pathetic in front of her. "Okay, just... don't put yourself under for my sake or anything, okay?"

"It'll be fine! We're friends right?" Mary shrugged, leaning down to give the orca a playful, actually soft shoulder nudge. "Now let's go get dressed. I'm bushed and gotta get back home if I'm gonna bake some more!"

"Ruh-right..." Nikki rubbed at her shoulders, thinking nothing of the last few words until she was nearly out of the gym. "She's gonna bake this late? Thought her lessons were during the day..." the orca checked her phone for the time, slinging her duffel bag with the strap over her right shoulder. Mary had gone off ahead.

As Nikki was exiting the gym, she stopped by the registration desk, standing to its side as something piqued her interest. "New posters?" she murmured, eyes bouncing from one motivational poster to the next. Guys and gals of various muscular builds with encouraging phrases were posing in ways that seemed to taunt the orca. In particular, the central poster which was the biggest one featured a massive red feathered hen with golden hair so long it reached her ankles.

The smug smirk on that avian's beak was well deserved: She was a rippling mountain of muscle, yet she could've also given Mary a run for her money in the curves' department. Nikki had never seen a woman so muscle-bound before. The idea of being that strong and powerful lit a fire in the orca's heart. She wasn't aspiring enough: She didn't want to settle with merely being Mary's equal, she had to be as big as that bodybuilder in the poster. She had to get even stronger than that!

But her back hurt like hell that night. The fire would have to continue burning on the next day...

"Cupcakes?" Nikki blinked a couple times in rapid succession, incredulity painted on her expression of disbelief.

"Cupcakes!" Mary repeated, lifting her right arm which was hooked through the handle of an adorable straw basket. Inside of the basket rested several colorful yet identical looking cupcakes. The dragoness fished one out to show it to Nikki, who stared at it for five silent seconds before Mary started nervously smiling, "Don't tell me you don't like sweets."

"It's not that. I'm trying to not get fat, Mary. I didn't come to the gym to eat cupcakes!"

"I know, but you do want this one!" Mary nodded, "I stayed up all night baking. Look at how cute they are! The instructor's been getting us into molecular gastronomy. The frosting looks like bubbles!"

"Molecular... what? What's science got to do with cupcakes?" Nikki gave the cupcake another glance. Indeed, upon closer inspection the frosting atop that decadent looking cake seemed to be made of tiny little bubbles sticking to each other, giving it an almost gelatinous appearance in spite of it emulating vanilla frosting.

"Some people think cooking's a science. And I signed up for this class with a really good teacher. And it's all about mixing stuff at a different level!" Mary explained with a twinkle in her eye, practically bouncing in place. "Super artistic stuff!"

"Yeah, it's pretty, but is it low carbs?" Nikki remarked.

"Even better!" Mary added, "This is densely-packed calories mixed with tons of the good stuff like proteins and many more vitamins than you could normally pack in a regular pastry! See, there's this total Daddy at the college I want to apply to. He's big and fluffy, and he's got this German accent! He's a beefy moth, with four bulky arms and a massive pair of..."

"...Mary you're drooling."

"Right! So he teaches chemistry there, and since I'm dating him right now he showed me the stuff in his test tube..."

Nikki intercepted again with a chuckle, "Double entendre."

"Lemme finish!" Mary flailed an arm with a big huff, putting the cupcake back inside the basket before calming down with a claw resting on her hips. "Okay, so... he's been working on a natural supplement. An energy booster! And it works! He like, says its could be diluted to make energy drinks or immune-immuno... something! Anyway, I swiped some to add to these. Used the techs my instructor at that course taught me too! Ooooh, let me tell you, he's a super Daddy too. He's a huge beefy bumblebee..."

"You've been on a multi-armed dude fuck train lately, haven't you?" Nikki deadpanned Mary, folding her arms and tapping her foot impatiently. The dragoness blushed, grinning a little.

"I can't help it! Beefy guys who know how to teach get my rocks off!" the Latina admitted, pressing a hand up to her cheek while poking her tongue out.

"What worries me more is that you swiped that energy boosting stuff your other "Daddy" made," Nikki smirked, "Won't you get in trouble?"

"Nah! He's throwing it out every day when he's done running experiments. He told me it's safe for consumption already, and if it's going into energy drinks, what better way to jam pack a lot of it inside one of my cupcakes!" Mary grinned, "And since it's going to help you beef up, I've even come up with a name for this recipe. We'll call 'em beefcakes!"

"Of course you'd call 'em that," Nikki rolled her eyes, cringing at the baker dragon. "So you're saying it'll help me grow big and strong, basically. No fat?"

"I even used almond milk as a substitute!" the dragoness said, "I guess they're vegan. Weird for something called a beefcake huh? Don't worry though, it's only the name. I made them like my usual vanilla ones for starter! Now c'mon, have one!"

Nikki had heard enough to declare Mary one quirky slut. But there was no mistaking the girl's ability when it came to baking. She still wasn't sold on the idea of molecular gastronomy or natural supplements, but those pastries looked and smelled delicious. She was hesitant at first, but the orca ended up shrugging and taking a cupcake from Mary's basket. "Just one. We aren't meant to be snacking right now anyway..." she said, giving that cupcake a quick once over. It was practically bedazzling and with the frosting reflecting light it was almost sparkling. She thought that if this upset her stomach she'd have an excuse to dip out on training for the day; her muscles were still store from the previous day.

"Go ahead! They're certifiably delicious. I made them after all!" Mary tapped her own chest proudly, her knockers wobbling inside of her sports bra.

Nikki leaned in, taking a quick whiff of that pastry. It smelled sweet, and somehow fresh even though Mary had said she'd baked them hours ago. The idea of an energy drink in the form of a pastry with all the necessary nutrients was too good to be true. Her stomach rumbled in response to the idea of eating something sweet and decadent; she'd been trying to hold back with snacks; not the easiest of tasks for a whale. Soon, her instincts kicked in and, chomp after chomp, the cupcake was gone. "Mmm..."

"Aaaaand?" Mary bounced on the balls of her feet, giddy for a review.

"Damn, Mary. That's some amazing gourmet shit," Nikki licked her lips off some of the leftover bubbly frosting. She thought of how much it reminded her of Italian meringue. Before she could add anything else however, the orca began to feel light headed and warm. For a moment, her sense of balance seemed to be failing her, but she caught herself with the help of her elbow and then a palm against the wall next to her.

"Nikki! Are you okay?" Mary set the basket down on the nearby bench, going down on one knee. She put a hand on Nikki's back out of concern, "Did it hit you too hard? Maybe you should've paced yourself..."

"Thu-that's... not how we killer whales do it," Nikki chuckled, and then laughed. She rebounded and twirled around, beaming at Mary. "Not gonna lie, that gave me one big jolt. Still feeling it! This shit actually works! I'm gonna go bench the heck out of those barbells now!" the blonde tossed her hair back, striking a double bicep curl pose before practically dashing off with exuberance Mary had never seen on the orca before.

Standing up, Mary put a hand to her mouth in surprise, "Oh my. Did I go a bit overboard with that compound? Hmm, he did say he was thinking of diluting it..." she began to nervously laugh, reaching down for her basket to carry it with her; she had to be cautious of anybody eating else eating those cupcakes. "Wait. Nikki! Do your warm up exercises first...!"

But as Mary caught up with her friend, she was further surprised by what she saw. There was Nikki lying down on the bench. She had gone ahead with the weightless barbell, actually warming up. What gave Mary pause was the rate at which the orca was pumping steel up and down. Even without any extra weight, the barbell should've weighed her down enough to make her shaky with her repetitions after the first dozen. Mary counted twenty and Nikki was still benching without breaking form. In fact, Mary had to ask her to stop by the thirtieth consecutive rep. "Nikki, you need a break after the first dozen- fifteen at most!"

"Right, right! But I can do it! This is nothing!" Nikki said, bringing the barbell down to the holder but without taking her hands off it. "C'mon, load this baby up already!"

"Alright," Mary set the basket down again where she could see it and huffed. She was going to have to pay extra attention to make sure Nikki didn't hurt herself with this newfound motivation! "5lbs. on each side should be..."

"You kidding? Load' er up, sister!" Nikki insisted. She was tensed and fired up. Mary was concerned, but figured she could graduate to the 10lbs. weights.

"Right. But you have to maintain form while doing each rep, alright? If it's too much, we'll go back down. Don't worry though, I'll spot you."

"Just keep your balloon tits out of the way," Nikki teased, shooting a Mary a playful wink. The dragoness effortlessly put one ten pound disc on each side of Nikki's barbell, screwing them in tightly before taking her place behind Nikki's head, standing over the bench.

"You're pretty eager. Alright, let's start. Shoot for 5 for now, okay?" Mary followed up with a concerned: "Do you want me to hold it for you to begin with?"

Nikki frowned, lifting the hefty barbell up above her head, "I'll be okay, mom! Jeez, let me do this already."

Mary wasn't sure what to do with all this energy now. At first, the way Nikki was holding the barbell up made her think the orca might've realized how heavy the equipment really was to her now; except Mary was proved wrong when Nikki let the barbell descend to just a couple inches above her voluminous chest before she started to push it back up with all the control and finesse Mary had taught her. And then she did it again. And again. One repetition after another went by and Nikki was doing such a good job not only was Mary unable to correct her, but she just kept going.

Before Mary knew it, she had counted twenty reps and was shocked when she realized she'd been so mesmerized by Nikki's technique she had forgotten to pace herself again! "Nikki, hold on, take a break."

"You're right!" the orca laughed, "This is too easy. Put on more weight!"

"What?"

"You heard me, cupcakes! Give me a challenge, here!" Nikki's eyes were filled with electricity, confidence practically pouring forth through that cocky smirk. Mary nervously laughed; she truly had not been expecting this much improvement in such a short time. But that was hardly a fraction of the beefcake's full array of effects on Nikki as Mary was about to find out.

As more weight was added and an increasing amount of exertion followed, Mary was soon watching Nikki change. Her tensed up muscles remained in their flexed state even when she distended, and they seemed to bulk up further when she pushed. The cycle of Nikki outdoing herself and further adding more and more weight seemed to be making the orca develop her muscles at an extraordinary rate. The orca's biceps and triceps were starting to pop out notably, especially during flexions. The straps of her sports bra were tightening on her swelling deltoids, her chest pushing out as the pectorals underneath gained further muscular definition and mass. With 30lbs. on each side of her barbell, the orca's muscles seemed to be growing with every rep! And that wasn't all.

It was hard to notice at first, but Mary could definitely see Nikki's body begin to stretch when the orca's head started sliding closer and closer to Mary's legs. The moment Nikki's face wasn't visible under Mary's rack, she knew something was off. Nikki wasn't merely getting more muscular, she was getting bigger all over! "Hey, ballenita, do you feel okay?"

"Okay?" Nikki repeated with a beaming grin, "This is the best I've felt in years! Hell, I feel like I could be lifting a fifty- no, a hundred more pounds! Bring it the fuck on!"

There was no mistake. Mary could see ahead and watch Nikki's legs sliding off the bench, her finned tail starting to coil on the floor as it covered more ground. Soon, it was impossible not to hear the creaking sound coming from the orca's snug outfit. Her waistband was starting to strain around her widening hips, the legs of her spandex shorts riding up her plump thighs higher and higher as they became too small on her swelling body. It wasn't long before Mary could see the effects plain as day on Nikki's sports bra which was having an increasingly harder time containing her immense whale breasts that were attempting to pop out of confinement. The areolae were already visible.

Warmth unlike anything she'd ever felt before made Nikki feel tingly all over. Her endorphin high was keeping her from feeling anything but pleasure even though everything from her muscles to her bones was swelling ever bigger. She was so busy with her work out that the feeling of expansion became assimilated to the joy of exerting her strength. The sexy orca's euphoria was growing with her!

Mary couldn't keep up with all of it. One the one hand, everything she was seeing was just as incredible as it was alluring. On the other, Nikki was probably a minute away from bursting out of her clothes and ending naked smack dab in the middle of the gym. "Alright, that's enough...!" the dragoness had to put a stop to this.

"What? Put the extra damn weight on! What do you mean it's enough? I'm hardly... oooh," Nikki's eyes widened as she looked up at Mary's thighs, realizing something was up with her point of view. Curiously looking to the side, she was mesmerized by the sight of her very own biceps practically popping out at her. She put the barbell back in its holder but she didn't get to do much as she sat up on the bench; Mary grabbed her by the arm and pulled her away to the locker room.

Fortunately for the two, the only other occupants at the girls' lockers were busy using the showers. Between the steam and the faucets' noise, they had great cover to talk. "Nikki, look at you!" Mary exclaimed, gesturing wildly with her claws.

"Hell yeah, look at me!" Nikki couldn't quit posing the second she had access to a mirror. She could make all the muscles in her arms stand out with minimum flexing. "Who knew those cupcakes could make benching so damn effective? Damn, look at my abs!" Nikki grinned, even her girl-abs had evolved into a proper six-pack. The moment she pulled her arms back to flex her torso however, the straps of her sports bra both gave out and with a loud snap they tore under the weight of her massive tits. "Oh whoops! Haha, too much for these rags!"

"Whoa...! They really are huge after all." Mary began to blush. It was hard not to see how much Nikki beat her in the chest department now that they were much closer in height.

With a smirk, the toned orca focused on her lower body. She hadn't lost roundness in her backside, and despite the additional muscle her thighs remained as delightfully thick as ever. With a flex, she burst out of her shorts and underwear, leaving her completely nude. "Boom! I'm so fucking strong. Yo, check this out, Mary. I think I'm just as big as you! Did that cupcake really do all of this?! Hey. Mary!"

"Oh... what? Ruh-right!" The spectacle had left Mary speechless for a change. She was so used to making others fall to admiring quietude due to her ludicrous strength that she had forgotten what it felt like. It was odd seeing another girl standing so close to her height. Nikki had grown so big! She had to be only half a foot shorter than her, maybe less! "I'm not sure it was supposed to do _all_of that. I mean, I thought it was just going to give you a little boost so you wouldn't get tired! Nobody in those tests I saw got any bigger. Do you feel sick at all...?"

"Of course I do! All of me looks sick! I'm kickass!" Nikki gave Mary a toothy grin, flexing with a power pose of her hands on her hips. "And you know what? I'm even up for more. I want to keep working out. I feel all hot inside- Like I'm about to blow up! I wanna go for more."

"For more? Are you sure?" Mary wasn't exactly opposed to the idea; but she didn't want her friend to suddenly fall ill. She had to admit this was making her curious. "Alright but if you start feeling off..."

"Told you I'll be fine! Stop being such a mom- I'm twice your fucking age, for crying out loud!" Nikki laughed, and was about to stomp out ready to tackle the whole world if she had to; but Mary stopped her by grabbing her wrist. "What now?!"

"Estás en bolas, loca." Mary hastily said; an Argentine expression to stress just how butt naked her crazy friend was. Nikki didn't have to speak Spanish to be able to read Mary's look of concern.

"...right. Uh..." Even though Nikki felt like she could suplex a peacekeeper right now, she was brought back to the reality that if she usually had to push perverts out of the way, she wouldn't be given her space to work out if she went out swinging her naked and now even huger tits around. "I don't suppose I can ask you for a change of clothes. My shit won't fit now."

"That's why I brought you in here, amiga. Let me check my locker..." Mary turned around to rummage among her things.

With a new, bigger sports bra and workout shorts combo and a fresh change of underwear from Mary, Nikki was feeling closer to the powerful woman she wanted to be. The bigger clothes fit her well even if the top felt a lot tighter than usual. "Bit snug up here... You're actually a size smaller than me, huh?" she snickered as she pulled on the straps of her sports bra. "I'd never have guessed. That's size difference for ya. But there isn't much of that now, is there, little Mary?"

With a huff, Mary glared down at Nikki, "I'm still taller than you."

"Yeah? For how long?" Nikki gave a shrug, turned around and sauntered out of the lockers. The dragoness had no comeback for that one. Was Nikki going to get even bigger? Mary wondered.

People gradually stopped working out in order to approach the new tall orca, and dragon girl exercise. For a change, Nikki didn't give the stink eye to all those stares; she was even enjoying herself! After all, she wasn't merely getting attention to herself because of her killer body; she was curling weights as heavy as Mary. The side by side between the two amazons making use of excessively hefty dumbbells was a spectacle of its own.

"Wow, you're quickly getting the hang of that weight too!" Mary remarked as she alternated arms, "Isn't it too much for you?"

"In your dreams! This is too easy. I could do this in my sleep now!" Nikki laughed out loud. "In fact," she paused, holding her own dumbbells down, "I'm gonna put even more weight on these. Why don't you do the same?"

"Because this is my routine. I'm not really looking to bulk out any more than this," Mary explained.

"Tsk, so all this time you weren't even showing me how strong you really are?" Nikki lifted an eyebrow, a certain part of her reignited ego feeling somehow bruised. With a huff, she knelt down to add more thick metal plates to her dumbbells, making them forty pounds heavier each. "That's the stuff! Mmnnghhyeah...!" with even more weight, the orca's biceps started to truly bulge out with every curl. She was finally starting to feel the strain after the first dozen reps. "Now we're talking!"

Nikki's enthusiasm was the talk of the gym. They were all curious to know where that massive, wild-haired cetacean beauty had come from and where the punky, soft looking one had gone. Mary was starting to get into it, feeling cheered up now that her friend seemed so happy with her new self. The idea of someone who could lift at her level also made her feel fired up!

As for Nikki herself, she was having the time of her life, but for some reason it suddenly didn't feel like it was enough. She was exerting herself with the additional weight, exerting herself, beginning to sweat again. And yet her body didn't feel warm or tingly like before. "Feeling numb..." she mumbled, being crept upon by burgeoning disappointment. She absolutely loved being almost 10ft. tall, making bulls and lions and even fellow whales look small; but it wasn't enough. She wasn't happy with her greater yet still limited strength, either. The sudden enhancement had, in the end, felt no different than fleeting excitement like a shooting star. "I want to feel that again..."

The orca's wishes were taking form in her mind. The fresh memory of that new sensation had all she was looking for. Nikki wanted to grow big; no, she wanted to be absolutely massive. She wasn't content with simply putting that Herculean hen she had seen on that poster the previous day to shame. She wanted to become so huge and powerful she'd never want to pose for any strength or size related thing again in her life. But to do that, she was going to need some help. She stopped working out and searched around Mary's feet until she saw the basket on her side of the weight rack. With a big grin, she thought: "If I got this big eating one of those 'beefcakes', then..."

Mary saw what was happening when the orca hungrily began to walk around her. A thought occurred to the dragoness: "What if she eats another one and really gets sick? I did go overboard with the supplement, and those volunteers didn't take more than one of the small doses..." Her mind was racing. She understood exactly what Nikki wanted but feared she might cause herself harm. The dragoness stood in Nikki's way, their enormous busts squishing together for much eye candy for everybody else in the gym.

"Dude, you're in the way," Nikki said. "I'm gonna eat more cupcakes."

"Wait..." Mary brought a hand up, her dumbbell being carried like a featherweight implement instead of the 300lbs. heavy duty monster it was. "How about I get them analyzed first? Just to make sure they really are safe for you after all..."

"Safe?" Nikki frowned, folded her arms under her impressive bust and cleaved an irate pair of blue eyes on Mary's. A smirk began to appear on the orca's black lips. "Oh, I see what's happening. You don't want me to eat more because you're afraid I'll get bigger than you. Don't wanna be the runt, huh?"

"It's not that at all," Mary puffed a cheek out in annoyance, "What if you eat one and get a stomachache or, like, explode or something?"

"Well, science stuff works that way. Try stuff, see what works. I don't think I'll explode though. I'm not that weak," the orca grinned, raising an arm and curling it back to expose her biceps, which she summarily kissed. "Not anymore!"

Mary rolled her eyes; she couldn't believe she was having to act like the adult for a change. "Don't be spoiled, just give me a little time to..."

"Look!" Nikki interrupted while dramatically pointing behind Mary, "That buff as fuck tarantula Daddy is deadlifting, benching and curling with all six arms...!"

Immediately, Mary turned around, mashing her palms down against her cheeks with love-hearts in place of her eyes, "Where?!" she squealed in delight. "Wait a minute... ack!" When she turned around, it was too late. The basket was gone from the floor, now hanging from Nikki's left arm. A couple of Mary's beefcakes were in her grip. Nikki didn't even take time savoring them, practically tossing them down the hatch in one swift swipe. All Mary plainly got to see was a big bulge traveling down her friend's neck before the orca let out a satisfied sigh.

"These are even tastier now!" Nikki said, throwing a third cupcake up and snapping it out of the air with her mouth. "Mmmm...!"

The dragoness began to mumble. "Uy, la puta madre..." Mary's heart began to sink, embarrassed by how easy she had been tricked and just as concerned by the gluttonous orca's actions. She was surprised Nikki had stopped eating by the third energizing pastry, but realized it wasn't that Nikki didn't want to; she couldn't.

The orca had stopped completely, her gloating silenced. The basket slid down over her arm, and it looked the killer whale was completely immobilized. That was of course, until she began to vibrate all over. A big grin grew on the orca's face as she began to swell in every direction all at once. "Yes! It's working!" she announced, making the nearby gym patrons take a step back as Nikki grew taller, soon meeting Mary eye to eye for the briefest of moments before she shot up even higher.

Once again, Nikki's outfit began to strain. With each additional inch, not only did the noise of fabric being pushed to its limits grew louder, but people could begin hearing the creaking and deep rumbling coming from that Amazonian orca. The first thing to go was Nikki's borrowed sports bra, her gigantic orca breasts simply tearing through it while bouncing spectacularly.

The dragoness had to actually step away too as Nikki rapidly overtook her in size and began to loom over her, her tits advancing forwards to fast they threatened to shove her out of the way! Mary could swear she was hearing sloshing now. But that wasn't all: Even though Nikki wasn't working out, her muscles continued to develop, becoming even thicker and more powerful!

"Mmmnnn...! This feels so great!" Nikki roared in delight as she watched her biceps and triceps just balloon out into spheres of power, her arms practically doubling in overall size. Her deltoids swelled too, resulting in her shoulders becoming wider and her back being free to accommodate even sturdier-looking muscle mass.

The way she was growing, Nikki pulsed and surged. Each time she flexed, her shorts came that much closer to ripping apart around her meaty thighs and hefty bubble butt. It didn't take long for her to shred out of what remained of her outfit. But she didn't care now. Whereas before the 12ft. tall cetacean had been reserved about being nude around a large multitude of people in the gym, their increasingly insignificant size made her think less and less about them like equals and more like happenstance admirers of her raw power and bigness. Her ego was swelling with the rest of her.

"Oh yeah! Watch this! I'm gonna get even bigger. This is only the start!" Nikki announced to the fearful and aroused crowd. Very few had any sense to run away. The rest were absolutely mesmerized by the fantastic, growing orca. She had to give her admirers a good show.

"Did she say bigger?"

"Those sweet tits look so firm!"

"I know! How does her back not hurt? And I thought Mary was too busty...!"

"Oh God, look...! She's lifting the entire pulley machine!"

"With just one arm, bitches!" Nikki boomed with laughter as she held the machine which she had cleanly ripped out of its fixtures. "There's nothing in this gym that could give me a challenge now! Rawr!" in her excitement, the enlarging blonde brought the pulley machine up and towards her other hand. She began to apply pressure from both sides, the sound of metal wincing as she compressed the equipment with sheer brute force.

"Wow!"

"She's crushing metal with her bare hands!"

Nikki drank all those awed remarks like the sweet praise she deserved. With every second that passed, her growing body made it easier and easier to crush the machine. Inevitably, it was brought together into a dense gathering at the middle, so she repeated the process with the bent top and bottom parts of the machine until the only thing remained of that pulley was a densely packed ball of scrap. "Hah! This was nothing...! Now watch me as I... oof...!" she winced and bent over, dropping the incredibly heavy scrap ball onto the ground, making a large depression on the now broken wooden flooring. Nikki had grown so tall she had hit her head on the ceiling.

Even adjusted for large species, the gym's ceiling was 15ft. tall from the floor, and Nikki had just exceeded that mark. "Fucking hell, the place's too small!"

"No, you're getting too big!" Mary finally chipped in, being the only one without shaking legs to approach Nikki from the side. "Nikki, you ate too many of those cupcakes. You only had to take one a day...! Are you okay? You hit your head pretty hard!"

"Quit worrying about me!" Nikki growled, laughing soon after. "I'm super strong now. I hardly felt it but now..." with every word, the orca seemed to swell larger. She was pulsing even now, having to lean lower as she bent over and pushed her back against the cracking ceiling. She had to begin pushing her palms up against the ceiling, and soon was down to one knee. Mary was so close the surge of size made Nikki's immense boobs pull her into their cleavage, "Place's too fucking small for me!"

The dragoness had to scramble for a good grip, and realized how strong Nikki was getting as not even her claws squeezing those sensitive looking huge killer whale tits got even a moan out of her. She briefly brushed her tail along the floor below, turning to look around for people. The ceiling was beginning to crack as Nikki grew past 20ft. tall, dust and concrete starting to rain down from the resulting fissures. "Hey! Show's over. Get the hell out of here, babosos! Hurry or you'll get crushed in here!"

Mary's shouting was effective at snapping most of those drooling onlookers out of their trance. Some had to be pulled away by the more lucid gym goers, but the late evacuation started right before that enlarging sea mammal finished filling out what little space remained in that downtown gym. The dragoness made sure to hold her breath as she heard the surfaces attempting to contain Nikki loudly protest her growth.

"Nnghh...! Running out of room! Fuck!" Nikki peered around the empty gym. At least she didn't have to feel bad if some dumbass got hurt; they seemed to all have cleared out. With how her thick tail now occupied the entirety of the west wing, she now understood it didn't matter how much she tried to compress herself; the site was doomed. As her right leg grew back into one of the walls and she felt her left knee poke the ceiling, Nikki got tired of holding the ceiling from collapsing, and instead furiously began gripping until her fingers bore holes into it. With a tight grip, she ripped the top of the gym off and sprang herself upwards.

Mighty tremors shook the entire block surrounding the gym. Nearby vehicles rattled so hard as a result that their alarms began blaring in unison. To Nikki who landed back on her feet this had been a regular old jump. To Mary who was still stuck in her cleavage, it was like being stuck between two gargantuan bouncy castles. To everybody else, an earthquake had just hit the city.

Stretching her amazing 30ft. tall form, Nikki let out a big sigh of relief once she tasted freedom. She had been enjoying her major growth spurt right up until she started running out of space inside the gym. Now that there was nothing holding her back, she could bask under the sun while she continued steadily climbing to newer heights. "Those beefcakes packed some punch! They made me into one!" Her arms stuck out so that she could observe their thickness properly.

Nikki took note of how easily it was for her to manipulate her newly acquired mass by tensing up. She was so delightfully bulky without compromising her naturally excessive curvature. Her abs had further developed muscle in her midsection, managing to fit an extra row for a complete 8-pack. Her quads perfectly balanced out her huge bubble butt, making her thighs the muscular show on the front while her ass showed off her sexy appeal behind her. She truly made that beefy hen from the posters look downright pathetic.

"Bwah!" came a voice close by, prompting Nikki to look away from her immense deltoids.

"Speaking of downright pathetic," the giant orca smirked as she finally took note of the captive between her breasts, looking smaller by the second as the growth continued. Nikki's ego was soaring now; she had to be four times bigger than Mary was now!

"Hey!" the dragoness huffed, clearly offended. "Who are you calling pathetic?" she glared up at Nikki, not even batting an eye as the whale surged another five feet taller in the short silence between their exchange. Never mind she was talking to somebody already on her way to being five times her size!

"How's it feel to be the runt for a change, Mary?" Nikki shrugged with an arrogant grin, and to further tease her small friend she pulled her arms in front of her ripped abs while tensing up her pectorals. She made her humongous orca tits wobble with her bouncing pecs, rattling Mary inside the squishy cleavage. "Am I huge..." she paused, biting her lip in delight as she experienced another swelling spurt that made her tower over the nearby office building, putting her officially at 50ft. tall, "...or am I huge?!"

"Huge fatass is what you are!" Mary snapped, but she was soon snickering as she glanced at Nikki pulling a broken old telephone pole from behind her and discarding it like junk.

With a bright blush, the giantess pressed Mary down using one thumb, sinking her back down in her cleavage, "Shut it! My ass just happened to grow into that! I guess all of this wasn't going to make my butt any flatter..." the blonde murmured, soon widening her eyes as she noticed her hand shake. The finger pushing Mary into her cleavage was vibrating and soon pulling back; no, it was being lifted back out. "Hmph. I forget how stupidly strong you are sometimes."

"Thanks! I work out! Do you even lift, ballenita?" Mary sarcastically added, pushing herself back out for fresh air and sunlight again.

"Very funny. You think I can't pin you down?" Nikki was determined to prove herself superior now that she was continuously becoming bigger. She couldn't lose to somebody a fraction of her size! Her burgeoning confidence prohibited it. First, she endured another pleasant swelling that put her at over 60ft. tall. Without the pleasurable distraction, she easily plucked the tiny dragon out from between her massive tits, smirking. "You're dangerously close to being bite-sized, dudette. I'd choose my words carefully if I were you."

"Are you seriously trying to get even fatter?" Mary raised her eyebrow at the titaness. "I thought you were looking to get buff!"

Frowning and baring her fangs, Nikki had heard enough. "That's it. You don't scare easy, I get it. I think I just gotta go for something more traditional intimidation for you! Let's see how sassy you are when I'm pinning you down!"

"Pinning me down...?" Mary gasped as she was suddenly slammed down into the gymnasium ruins. The impact knocked the wind out of her, giving Nikki the opportunity to lift her massive hand off her and lift her foot. Nikki's grin was briefly hidden from Mary thanks to the orca's immense bust being in the way, but since Nikki needed to aim she had to lean over until she could make Mary out where she'd set her down. With the black sole of the giant killer whale's right foot bearing down on Mary, the dragoness held her arms out just in time as that foot came down.

"How's that?" the muscle bound orca giggled, resting her hands on her powerful hips as she pinned Mary down. Nikki knew she didn't have to hold back with a super strong dragon like her. "Feel the pressure yet?"

Mary's muscles began to strain as she exerted her strength in trying to push against several tons of orca trying to flatten her like a pancake. "Are you kidding me?! Get your foot off me, Nikki!"

"Maybe I will!" Nikki shrugged, "But first, you gotta admit I'm the top bitch now. I'm the biggest!" she laughed, not even needing to put more pressure on her foot as she swelled even taller, "And only getting bigger! Better hurry before I smoosh you!"

With a growl, Mary began to notice her arms were failing to hold all that weight up without her limbs shaking. She was quickly starting to lose and Nikki wasn't even trying to truly stomp her down. For the first time, she was starting to feel challenged and she wasn't very much into Nikki's smug attitude. "Get off your high horse! You're only that big because of my beefcakes!"

"And thank you very much for those, by the way," Nikki grinned, "You've made me into a goddess, Mary. I can't love you enough! But as any goddess, I need total submission from lesser mortals. It's not just you- I'll make everybody understand who's the strongest! And I'm starting with you; ain't I the best?"

Mary could feel her strength approaching its limits. With every arrogant word coming out of Nikki's stupid sexy black lips, she could feel the fire burning inside of her getting further stoked. However, it didn't matter how strong her densely packed muscles were; Nikki's foot was simply too big, and her weight was only increasing the bigger she got. She had to think quick! Looking around, she saw something she could use and decided to go for it with her tail.

"I don't wanna crush you, shrimp," Nikki began to pull back, making sure to keep her foot on top of Mary without applying any more pressure than absolutely necessary. "Look, I'll make it easier: Just call me mistress. I promise I won't tell anyone; they all ran away from me anyway! I'll teach them a lesson later." Looking out into the distance, Nikki got a good sight of the city as her perspective continued elevating with her height. It wasn't going to be long before she started competing with the taller buildings for size! "Say, you're pretty quiet down there. But I can still feel you pushing. C'mon, don't be a sore loser..." Nikki's words trailed off as she felt an unfamiliar rumbling coming from below. It wasn't coming from the ground; it was coming from Mary herself.

"Who are you calling a shrimp, fish?" Mary licked her lips clean of frosting, wiping the rest off her face with her tail. The basket she had secured had miraculously been undamaged, and the remaining two of the half-dozen cupcakes she'd brought were now in her stomach. The effects were immediate and the dragoness burst out of her clothes as her body began to swell bigger and bigger.

It was hard for Mary to hold back her moans of pleasure. Although her muscles weren't getting any bigger, the tingling wreaking havoc with her senses was enough to get the burgeoning Latina hooked onto the wonderful feeling of expansion. She could feel the burst of energy revitalizing her, invigorating her arms which enabled her to push back with less restriction.

Nikki's eyes widened and she nearly stumbled backwards as she felt the toned amazon grow underfoot. Mary eventually became visible to Nikki who desperately stomped down to keep her pinned down. However, as Mary grew, her strength increased in proportion, and Nikki was soon using all of her might to try to keep that dragon down. "Fuck! Are you kidding me? How did you...?"

"Should've eaten them all, amiga!" Mary triumphantly pushed back as she slid against the ground, further crushing what little remained of the gym under her rapidly growing body. She had already doubled her initial size, and although her twenty feet of height couldn't yet compare to Nikki's colossal hundred, her Herculean strength was more than capable of fighting back against that supersized cetacean!

"I ate more than you, what the fuck?"

"I guess I was already big and strong, so two was more than enough!" Mary reasoned. She surged bigger still, her legs straddling Nikki's standing foot while she hugged her arms and bust around the orca's stomping foot. "Karma's a bitch, 'ey?"

"Let go...!" a furious Nikki kicked her foot. The grip from Mary's legs made it impossible to get rid of her with one kick, so she tried again, and again, eventually crouching down and using her hands to force Mary's legs off her feet. This allowed her to kick forwards with enough strength to finally shove the giant dragoness away. "Fuck, you're persistent!"

Crashing backwards, Mary found herself in the middle of the street. The pavement cracked and fissured all over as she got up to her feet, stretching to her new 30ft. height. "Ooh, cars look really small down there now!" she observed, curious about her shrunken surroundings now that she was so big. A looming shadow cut Mary's break time short. That musclebound orca still towered over her. Even with all the growing she'd done, Nikki was still enlarging; she had to be four times her size!

"You're looking really small down there, still," Nikki smirked, "Fine. It's no fun if there's no obstacles in the way. I'm gonna have you kissing my ass in no time."

With arms folded under her bust, the smaller giantess glanced at Nikki's hips from side to side, tilting her head to get a good profile view. "It is a pretty smoochable tush, not gonna lie!"

"Whu-wha...?" Nikki hadn't been expecting that response, and the lapse in focus was all Mary needed to close in on her with a rapid lunge. Before the monstrously big orca could do anything, she found herself looking at the sky, her back slammed down onto the gym ruins. With an impact that heavy, vehicles in immediate proximity were knocked up into the air for moments before crashing down. Their alarms weren't blaring anymore after that.

"Got'cha, bitch!" Mary put a foot down on Nikki's 8-pack, twisting one of her arms back while pressing down on the orca's immense chest.

Embarrassed but unhurt, Nikki was starting to lose her patience. Without even opening her mouth this time she retaliated by swiping the cocky dragoness off her with her free arm, seizing her by the waist before tossing her at a nearby building. "No, I got'cha, bitch." She quickly stood up, debris from the ruins rolling down her perfectly muscular body. "Don't underestimate me just because you're stronger. I got buff, too!"

With concrete, glass and metal raining down upon her, Mary could do little more than brace as the 50ft. tall building she had crashed into crumbled down. She emerged from the resulting dust cloud even bigger than the destroyed apartment. She was grinning instead of angry, holding her shoulder as she cracked her neck and stretched her arms.

As they crossed gazes, the two giantesses smirked at each other. Without having to verbally communicate their thought had become one and the same: They were going to play rough.

Downtown's evacuation efforts were going underway as the giant breasted women met head on in a hand lock. Mary was catching up to Nikki's 150ft. tall size. She was still quite far away with her eyes barely able to meet up with the orca's thighs, but her grip was still as powerful as ever.

"What's the matter? Losing your nerve?" Mary taunted, taking a step forwards and burying her head underneath the orca's titanic boobs. She was pushing the much larger giantess back.

Nikki cursed as she felt herself skidding back bit by bit. Smaller shops and buildings were razed by her legs, lasting for barely a few seconds before they were demolished. The orca still was trying to figure out her own new strength, so competing with another experienced meathead was being difficult even if she had the size advantage. Tensing up, Nikki's bulky muscles bulged out explosively. She growled and pushed right back, sinking Mary's feet under the asphalt. "There! Shut it already!"

Desperate as Nikki was to win, Mary was having fun. She couldn't remember the last time anybody had made her sweat like this! And the best part was she didn't have to hold back with Nikki now that she was such a titan. With that perfect blend between muscles and curves she was such a looker too! "Mmm... why are these so freaking sloshy? Are you hiding a dairy in here, Nikkicakes?"

"What?!" Nikki looked down at Mary, or tried to anyway; her huge tits were in the way. Blushing, the blonde became frustrated and shoved herself down on Mary even harder. "Stop fucking around. Just because my tits are bigger than yours..."

"Not that much bigger!" Mary snapped as she pushed back. Inevitably, she lifted a foot outside of the hole in the asphalt and took a step forwards, beginning to push Nikki back anew. "Lemme just catch up to your size and you'll see...!" she playfully growled, shoving herself up against the orca's tits until they bounced her away. They had hit an obstacle.

Nikki glanced back at one of the largest shopping centers in the city. A mega mall spanning an entire block with its top floor being over fifteen stories tall. With how Mary kept pushing her, Nikki felt her ass starting to crunch down on the mall, her tail draping around the large construction. "Quit pushing dammit!" Nikki grunted, reaching down to grab Mary by the head to stuff it in her cleavage.

"Hey...! Mmmpph!" Mary was muffled by orca boobs as Nikki squeezed them around her head. She could hear that slushiness again, now even louder with her ears pressed by those tremendous cetacean jugs.

"Ah! Quit squirming around so much...!" Nikki realized how little control she had over the situation now that Mary was desperately trying to free herself from the squishy prison. In trying to stop Mary she had only made the dragoness struggle harder and Nikki ended getting toppled over atop the mega mall. Their combined weight was simply too much for the mall. Their growth had left them at 100 and 200ft. tall with Nikki still taking the lead, and this was bad news for anyone looking to do a shopping spree anytime soon.

At first, the most impressive building in the city seemed to be resisting, acting like some sort of sturdy bed. However, no construction had ever been built to last under that much weight, inevitably falling to the unexpected pressure. It was crushed underneath Nikki's muscular back and gigantic ass.

"Mmnngh... ahh!" Mary finally pulled herself back outside, her hands sunk against the softness of that orca's huge bosom. Nikki couldn't hold back the moan of pleasure; she was big and beefy all over, but there definitely was no sensitivity lacking on her chest. "These are some badass weapons."

"I know. You've knocked me out with yours more than once, you top heavy meathead."

"Hey! Just so you know, I got pretty good grades in English this semester!" Mary seemed proud to be showing off about her academics; but of course she had left out her poor marks for history and math. "Also, get topped!"

"You got so big so fast, too. What the hell?" Nikki peered down at the dragoness only half her size, grumbling. "...nghh... don't squeeze them so hard."

Smirking, Mary sank her fingers as far as they could go into the orca's mammary flesh. Each huge sphere would've easily been able to crush a regular suburban house with little trouble. And the dragoness was just toying with the dangerously oversized breasts. "They're so soft and squishy. And sloshy!" she remarked, "C'monnnn, what're you hiding in here, vaquita?"

"...that's a new one..." Nikki had never heard that Spanish word before. When Mary explained it was the diminutive form of "cow", her cheeks went red. "Who do you think you're calling a little cow?!"

"Right, right. You're more of a vaquita marina, right?" Mary thought that the "sea cow" title fit her friend just fine.

"Dude! That doesn't make it better! Get the fuck off my ooooohh...!" Nikki began to moan out loud when Mary gave her a good fondling squeeze. The dragoness' claws traced that soft flesh all the way up to the areolae, where she began to push her digits up against her fingers.

"There's a lot of pressure in here. Jeez, Nikki, no wonder you were tense as hell back at the gym!" Mary observed as she watched the tip of the orca's hardening nipples begin to get wet with creamy white liquid. "Just look at how much milk is coming ouuuuuut!" she sang out playfully.

Clenching her fangs down, Nikki closed her eyes and curled her toes. Her fists closed around sections of the flattened mega mall under them, squeezing the rubble as she fought back against the reluctant pleasure she was receiving. She had no way to stop herself from lactating now, so after a sigh of defeated, she confessed: "I didn't milk myself this morning like I was supposed to. All backed up... Gets me all moody and shit..." she muttered at the end.

"I don't think I've ever had orca milk before. Well, it'd be a waste if I just let it pour out like this!" Mary boldly stated, pulling on Nikki's left nipple before grasping the areola like a giant stress ball.

"Mmngh! Whu-what are you doing?!" the muscular sea titan wanted to stop Mary, too embarrassed to let her continue. But the pleasure was so much and the milk pouring forth felt like such a relief that her hesitation allowed Mary to do as she pleased. Before she knew it, Nikki had Mary's snout right next to her nipple, the white haired Latina dragging her long, reptilian tongue over its sensitive skin. "Ahhhh... f-fuck it feels good."

With a chuckle and no further commentary, Mary squeezed down on that nipple to make it pop out between her fingers. She closed her maw on it, capturing the lactating nub in her warm mouth. Mary then suckled to the sound of Nikki's moans of satisfaction. The orca squirmed helplessly, rapidly getting wet between the legs as she felt an increasing amount of relieved pressure with every mouthful the dragoness extracted and summarily gulped down.

The process continued for a full minute before Mary switched to the other nipple. Nikki was soon in heaven again as the dragoness drank from her heaving bosom without pause. The other nipple continued to lactate freely. Mary didn't leave it out and continued milking it with her fingers, making Nikki squirm and squeeze her thighs together, reaching down to play with herself. "Fuuuck...! It feels so good!"

"Am I gonna hear you moo?" Mary softly said, licking her chops noisily to clear her cheeks off dribbling milk. A huffy Nikki shoved Mary's head down.

"Cut it out with the cow stuff already! I'm a cetacean, not a bovine!" Nikki fumed. Mary lifted her head up with her overpowering strength, glancing up at the furious Nikki.

"Both are mammals though, right?"

"Shut up and keep sucking, smartass!" Nikki put both of her hands on Mary's head, shoving her down so hard she stuck a large portion of boob in addition to her nipple inside of Mary's maw. The dragoness had no choice but to nurse off her, and soon enough Nikki was left moaning her head off to the milking again.

And though this harmless looking activity wasn't having the giantesses actively wreck the city, their unstoppable growth continued making them stretch along the ground. Nikki in particular was covering more and more of the mega mall under her back, rump and legs. Biting her lips she looked to the side at the increasingly more pathetic city. She wondered just how much more they would continue growing; and if Mary was going to make it to her own size too.

By the time Mary had mostly emptied Nikki out, the orca had become sufficiently pacified to the point it was easy for the dragoness to pull herself back and appreciate her handiwork. "Now there's a happy looking ballenita! You really needed that, huh?"

"Yeah... Thanks," Nikki mumbled, frowning up as she realized Mary was stretching ever taller than before. Nikki had almost made it to 300ft. tall throughout the milking session, but she was lucky if she had fifty feet on Mary now! "How come you're growing so much faster?"

"I dunno. I just used the ingredients. I'm just a baker! Ask me about the kickass frosting decoration; I'm really proud of that one!"

"How the heck can you be thinking about cupcake decorations at a time like this...? You really are an airhead."

"So, we're two giants! And it feels great," Mary reasoned, "Why sweat the details now?"

"I suppose you're right... Hmph, I wanted to be the bigger and stronger one!"

"Psh, good luck!" Mary giggled, stepping off Nikki. Her enormous clawed feet hit the pavement hard enough to send fissures down the street for several yards around her. The immense dragoness tossed her long hair back and offered a claw to help Nikki back up. "There's a reason I got you beat. I got more experience! That's all."

"That's all..." Nikki mumbled mockingly, accepting Mary's help up. Pieces of the mega mart which had become stuck on her back and ass crack started raining down as she stepped down on the ruined shopping center. The orca was at the very least pleased she was still several heads taller than her fellow macro amazon. "But I got the bigger muscles!" she insisted, flexing her enormous arms before pointing down several blocks away, "I bet I can lift that bank- no, the entire block!"

"You can, huh?" Mary smiled, stepping outside the way and gesturing towards Nikki's target. "Show me how it's done, amiga."

"I'll show you more than that, amiga," Nikki retorted, cracking her knuckles and tensing up as she began to stomp towards the bank on the west side of the city. "That this beef ain't just for show!" she shouted as she squatted in front of the bank, starting to analyze her plan of attack.

Mary carefully observed, her eyes inevitably wandering down when Nikki bent over. In spite of how bulky and muscular she had become, the orca's fat ass had remained its spherical shape and bubbly firmness. It was impossible not to stare at that huge peach. The abandoned cars left by the bank rattled with each clap produced by the whale's extra thick rump cheeks. "Now that's a traffic-stopping ass!" cat called the dragoness with a whistle.

"Shut the fuck up!" Nikki dug her fingers into the asphalt, creating deep holes and tensed up once again. With a smug smile, she added a softer: "And watch!" as she began to apply force upwards. She could feel the foundations of the walkway starting to give against her strength. It was hard not to tear it all apart and uproot it in pieces. She had to begin anew several times, looking like a kid attempting to pull up a sand castle with their bare hands.

Nikki dug deeper and deeper until she hit a more resistant part below the foundations, several buildings block-wide shuddering and quaking as the giant orca began shoving before gripping as tight as she could. The crust below felt like crumbly bricks to Nikki, but she found out she could compress it into a densely packed bunch of mass until it was sturdy enough to not disintegrate under her strength. When she was sure of what she was doing, the orca grinned and pulled her arms out, extending them as far away from each other as she could before digging down from farther away.

Mary's derriere reconnaissance was interrupted when the shattered pavement under her feet began to tremble. "Hija de puta... She's doing it!" the dragoness incredulously stared as she saw not one building, but the entire block in front of that killer whale being extracted, crust and all, out of the city. "Holy shit! Awesome stuff, Nikkicakes! Go go!" she cheered the blonde.

Lifting all that weight was truly putting Nikki's new muscles to the test. She not only had to apply brute force, but maintain balance so that the crust did not slip off her hands and ruin the fine job. Now that she was bringing an entire block up with her bare hands, she was sure she could've just ripped any old building up; but she was glad she'd decided to show off. Soon, she began to stretch her legs and pull the city block up to her chest level, and then above her shoulders, and finally she held the entirety of it above her head! "How's THIS?! I rule!"

What was left in place of the block was a concave indentation; a gargantuan dirt hole where dozens of buildings used to be. And those edifices were now sky high over 400ft. above!

But Nikki's moment under the sun was cut short when suddenly she felt a ticklish sensation spreading from her mid-section. "Coochie coochie coo...!"

"Ahh! Mary, goddamnit!" the orca's legs began to wobble as she could hardly contain herself when her fellow giantess dashed up to her only to begin tickling her belly. "Quiddit! Fuck, hahaha...! You're gonna make me...!" With the way Nikki was shaking and wobbling, the buildings above started to fall apart, debris, vehicles from parking lots, signs and even food stands falling over the floating city block around Nikki.

"I got it!" Mary laughed, extending her arms upwards to catch the falling crust as Nikki finally dropped it. She dug her claws up, salvaging the situation just in time for Nikki to get her revenge and assault Mary with her own tickling barrage. "Ahh! Wait hahaha, n-no! I was just joking around...! Eeeeahahaha...!"

"Aha! You're ticklish too! I'm not letting you escape after that!" Nikki deviously went for making the Latina squirm. She knew that the dragoness was way more disciplined with her strength, even if she had a hard time holding herself back sometimes. But that advantage of being able to hold up all that weight without dropping it was only going to bite her in the ass now that Nikki was going for broke with her counter-attack.

Before Mary could tell what was going on, she was paying back for her teasing with interest. She could only squirm in place, barely able to walk away with the city block above her head as Nikki prodded her sides and tickled over her smooth girl-abs. "S-stop! I get it! I get it already ahahahaha...!" she was crying with laughter.

"No way!" Nikki hugged herself to Mary so that she wasn't going to be able to escape. She gripped the latina's muscular booty with a steely grip, pushing her snout up against Mary's belly button to begin blowing raspberries against it.

"N-nuuuuuuhh...! AAAHHAHAA...!"

There was a loud crunch. The crust above them cracked all over as Mary's claws gripped so hard, so powerfully, that even the dense mass of earth she was clenching her digits into started to shatter. In the end, Mary's monstrous strength shone once more as her magnified size allowed her to smash it all to pieces. Soon, the pieces were raining all over them both. "O-oops... hahahaaaa...!"

"Get owned, Mary!" Nikki grinned, hiding her head from the falling debris under Mary's tits.

"Dang. I guess I had that one coming," Mary shook her head, coughing up some dust. She saw Nikki's head pop out through her cleavage. "What?"

Nikki stared at Mary and couldn't help chuckling. She pulled herself up and pushed her snout against Mary's, nuzzling her a little. The dragoness blushed a little, making Nikki smirk. "Had dirt all over ya, dork. But since we're this close, and my hands are still on your sweet ass..."

Without even time to blink, Mary briefly froze as Nikki pushed herself in for a peck. Their lips connected once, then again after a rebound and then their mouths lightly opened to deepen it into a kiss. The dragoness' claws fell upon Nikki's shoulders as they both relaxed.

"Mmm..." they exchanged affection through a long lasting smooch. Nikki's plumper lower lips softly squished against Mary's smaller reptilian ones. And exploiting her initiative, Nikki pushed her tongue in, reigning Mary in by squeezing her buttocks in her hands with a tighter grip.

Starting to kneel down as she went limp, Mary wobbled with her feet at the edge of the crater left behind by their contest of strength. She slipped back and fell in with Nikki on top. Their positions were reversed from earlier, and Nikki wasn't going to waste this opportunity to show Mary a good time just as she had helped her with her milky breasts.

Mary moaned into the kiss as Nikki not only manhandled her muscular ass cheeks, but also rubbed herself up on the smooth-scaled beauty. Their breasts squishing together made the dragoness squirm in delight. With uninterrupted and continuous growth, the block-sized hole was progressively filled up by the horny giantesses. Focused only on making out and feeling their bodies press up together, their surroundings metaphorically melted away.

Neighboring city blocks got crushed, buried under Mary's bulk as she continued to grow larger with Nikki on top. They had become so big they were both about to hit the 400ft. tall mark and the city was feeling it, now even more thanks to their wallowed in their affections.

Bringing a hand back under Mary's thighs and boldly exploring the younger girl's groin, she was pleased to find out she wasn't the only one with a wet crotch. As their tongues intertwined in that deep make out session, Nikki cranked the oven's dial up another notch by dragging her hand up from Mary's taint to her womanhood. She arched her wrist a little, pushing with her middle and ring fingers as gently as she could until she was pressing them up against Mary's vulva.

The blue and white amazon was struggling to keep herself in control. It wasn't the first time she'd kissed a girl, and by no means this was the first time another woman had touched her. But she was genuinely surprised when a punky girl like Nikki turned out to be so gentle with her touch. It was enough to make Mary continue fighting her fiery instincts and allow the orca to have her way with her.

Fortunately for Mary, Nikki didn't keep her waiting for long. Her blonde friend quit the kiss for a moment, pulling back at the same time as she brought a hand up. She dragged her tongue over two of her glistening fingers, making Mary watch as she licked them clean of her juices.

"That's hot..." Mary said, her cheeks flushed a deep kink. For all of her promiscuity, she wasn't as used to seeing other women slurp her fluids in such a titillating manner; they were usually intimidated into submission by her. Instead, Nikki was, as always, playing the overtly dominant role. And yet, for once, Mary didn't feel like competing.

The dragoness' eyes widely opened as Nikki dove down for round two of their French kiss. She had seen it in the perverse glance coming from the orca's blue eyes; she wanted Mary to taste herself. And now that their saliva was intermingling with the unique flavor, that tongue kiss was that much more arousing than before.

Gradually testing the waters, Nikki rubbed her lower body up and down on Mary's legs, looking for a comfortable position for their girl parts to make contact. In the end, she saw no better solution than the classic. With a bit of help from Mary, their legs interlocked and Nikki began to slide herself up without breaking the kiss.

As their wet temples met for the first time, Mary shared a hiss with Nikki. Their puffy vulvas squelched as Nikki pushed her hips down on Mary. Accurate pelvic movement guided the orca's erected clitoris bulb over Mary's, causing the dragoness to curl her toes and clench her fists.

The friction resulting from their constant grinding was enough to drive Mary nuts. She couldn't help wanting to make it even better for Nikki, bringing her claws forth for some action. One held onto Nikki's right boob while the other seized her left buttock. The squishiness of those fat curves was enough to melt stress away.

And the moaning Nikki wasn't simply going to sit there and be the only one to get touched all over. Despite her liking Mary's round behind, she brought both hands up to the Latina's immense marshmallows. Everything about the dragoness screamed toned and firm; even her breasts. Unlike the rest of her body though, those huge, perky tits that looked so big on Mary's athletic frame were deceitfully soft and malleable. "They're so tender and soft...!" Nikki admired as she toyed with her fellow giantess' boobs.

The city continued to fall to the lovemaking giants. For all their growth doing the damage by itself, passionate flames were being stoked with every second those burning pussies rubbed against each other. They didn't merely remain in the same spot, inevitably rolling out while twisting and dragging themselves through the ruins they were creating. Billboards were sent flying through the sky. Trusty water tanks burst as they rolled into them, getting lightly splashed here and there enough to make them hiss to the coolness before they resumed their fiery humping and endless smooching.

It wasn't long before all that sexual energy began to affect Mary and Nikki's growth. They were blissfully unaware at first, but their makeshift downtown bed certainly felt it when they began shooting up hundreds of feet taller at a time. Together they smothered the city under their massive curves all the while fucking each other senseless. The two overpowered gym bunnies were as unbridled as they were unstoppable and soon enough they began to measure in the thousands, and then miles.

Sparks seemed to fly out in the air as they experienced their first orgasm together. Sexual climax sent squirts of girl juice all over the city, flooding it in excessive vaginal juice. And even then they didn't stop, their frenetic humping getting even less inhibited as they thoroughly enjoyed each other's bodies. Tits and asses were squeezed. Tongues wetly wrestled for dominance, moving the ring from one's mouth to the other's. Their sexual rampage was annihilating the ever shrinking city.

When Mary finally took charge and pulled herself on top, she dragged Nikki's gargantuan ass over the entire west side of the city, the orca groaning out in delight as bits and pieces below sank against her squishy behind and the larger, sturdier structures were wedged into her crack. Mary seemed intent on shoving that big orca butt over as many things as possible. "Whu-what are you doing, dude...?" Nikki murmured, her eyes half-open, her face drunk with pleasure. "You keep pushing junk up in there, what...?"

"I've seen the way you keep shaking this booty, Nikkicakes," Mary grinned down at her friend, this time making her squirm by squishing their immense chests together. "I thought of fingering it, but I thought of something... kinkier. We don't have that many options for toys though so..." the dragoness' wet fingers pressed together a bunch of those diminutive objects until they were mashed together into a thick shape. She kept adding to it and pressed it as hard as she could, molding it into longer dimensions until she could begin prodding Nikki's backside with it.

"Ah...!" Nikki moaned out loud, feeling her tail hole stretch when Mary began to violate her behind with a makeshift dildo made of city. "Fuuuuuuck that feels good!" the orca panted, having difficulties to relax at first. She did her best to squeeze her thighs together and continue humping back against Mary, but the sudden anal stimulation was enough to bring Nikki's inner buttslut out. Her tongue lolled out of her maw, drool dripping out in heavy volumes. "M-muh-more... push it deeper!"

Mary was only too eager to comply. Soon enough she was fucking Nikki not only with pussy on pussy action, but also shoving that improvised toy in and out of the whale's fat ass. "That's it ballenita. You like this, don't you?" Mary's motions were unrefined and brutish, but nonetheless effective. She was stretching out Nikki until she couldn't anymore. However, it wasn't because Mary had given up. Inevitably, their growth made not only Mary's hand too big to properly handle that tool, it made Nikki's butt large enough to fit more than the totality of the dildo. In the end, Mary was left totally empty handed, and Nikki was a happily stuffed orca. "Whu-whoa...! Your ass ate my toy!"

"What do you mean my ass ate... Did you lose that thing inside me?!" Nikki grumbled, her face red as a tomato. But she didn't seem as bothered now that she wasn't properly feeling the stretching she had been, before. "It... it feels like it's getting smaller! Hold on... Mary what exactly did you use to make...?" When Nikki stopped humping because of her curiosity, she didn't expect looking out around them would show her the neighboring city limits, the highway on the other side of town and several acres of the farmlands beyond!

"When did we get THIS big?!" Mary was just as shocked. The landscape reminded her of flying on a plane and looking down at tiny dioramas of cities below. After Nikki brought her attention away from naughtiness, she could finally see how utterly colossal she and her friend had become. "This is amazing! But then again... we did eat many beefcakes, heehee!"

"Can't believe how strong that stuff was. You said nobody grew back in the experimental phase, didn't ya?"

"Mmmhm! But then again, maybe those machines I used in the mixing process had something to do with it. Maybe I made the supplement super strong by accident!" Mary giggled, rearing back and flexing both of her arms for emphasis.

"Well, you won't have me complaining. I love being this freaking huge! Look at us, we're on top of the world! Almost literally!" Nikki laughed. She groaned as Mary turned her around. "What're you..."

"You just reminded me I haven't paid you back for the whole goddess thing back when we could still make out buildings!" Mary sang out as she sat back and laid Nikki across her lap. She kept the muscle bound orca down on her lap. Now that their size relative to one another had mostly equalized, it wasn't hard to manhandle Nikki entirely like she was used to!

"H-hey, I was just joking. Y'know, the power had gone to my head and everything!" Nikki pleaded, nervously laughing. She hated to admit it but her bigger muscles didn't seem like much use against Mary when she had her laid down like that. "Just forget and let'sahhhhh...!" she squeaked.

Mary's claw came with thunderous might, slapping Nikki across her perfectly bubbly butt. The smack was so powerful it caused the curvy orca's rump to wobble incessantly for a few seconds during which her hefty buttocks clapped together.

"Thu-that's too hard, man!" Nikki wiggled her hips helplessly, "Can't you hold back a little...?"

"What?" Mary cocked an eyebrow, smirking down at the blonde, "How could I ever think of holding back against a goddess so big and mighty?" she grinned, rearing back and spanking Nikki again. And again, and again. It looked like punishment, but Nikki seemed to be doing very little to fight back.

"Ffffuck...! It feels good..." the orca muttered in the low, holding her head to look like she was in pain even though she was secretly enjoying her "comeuppance".

It took Mary a few extra smacks but she finally caught on. She began to grin even wider, putting even more effort in adding in a few extra gropes and fondles here and there between smacks. With each new spank, it seemed like Nikki's act was being dropped in favor of her screaming out in bliss. "You really like attention to your big butt, huh? I thought all this time it embarrassed you!"

"F-fuck no, nnghh!" Another spank. "I have a hot as hell body, eeeep...!" Another fondle followed by pinching. "I just wanted to get beefy, too! Now keep spanking me!"

"Oh my." Mary couldn't have hoped for a more amusing show. Between Nikki's rapidly exposing kinky side and the constant view of everything around them becoming increasingly tinier, the dragoness didn't need physical stimulation to be just as turned on as the orca. "Just how far do you want me to take this?" she groped Nikki's tail base to keep her tail from swinging around, pulling on it to make Nikki hike her ass up higher. The titanic killer whale 'cheeks were rosy from all the spanking, yet Mary had a feeling Nikki was enamored with the treatment. She could only think of making her reach Heaven, though.

A proverbial light bulb lit up above the young dragoness' head. Mary's claw wedged in-between Nikki's butt cheeks, spreading them nicely until she could touch her winking pucker with her knuckles. She teased the blonde for a few torturous seconds just shoving one finger in and out, harmlessly scratching the inside and making Nikki whimper for more.

"More?" Mary thought about it and added a second finger. The increased snugness made her penetration slower, clumsier, yet Nikki seemed pleased with it. She was reaching out with her beefy arms, slamming her palms down over the countryside as desperation built up. "More?" Mary repeated, adding a third. When Nikki began to rip out chunks of land and dig her toes into the neighboring city on the other side, Mary understood that orca truly had a hunger she wouldn't be able to satiate by pacing herself.

"Nnghhh!" Nikki's eyes bulged out, screaming her lungs out as her rectal walls were pushed to their limit all at once. "AHHHH! FUCK!" she swore and kicked her feet down, decimating whole urban areas with her feet and ruining hundreds of acres with her fingers. Clenching her teeth to stifle whimpers of mixed pain and pleasure, Nikki could feel her sphincter's attempt to clamp down on Mary's invading fist. "T-too much... but... oh fuck don't stop now...!"

"Jeez...! You really want this, don't you?" Mary could feel the wetness pour down over her lap. Nikki was really enjoying this! And despite how incredible the situation seemed, Mary was getting off on exploiting her friend's anal fixation. Not wanting to significantly harm her however, the dragoness for once tried to be as considerate as possible with shallow, swift fist pumps.

"Ahh! Fuck, yes! Feels so good. Feels so goooooooood...!"

There was no stopping now. Mary drove her fist in and out of Nikki's ass with ceaseless effort. The dragoness lost count on how many orgasms she wrenched out of the orca with this wicked practice, but she did her best to satisfy her friend's appetite.

When Mary was done with Nikki, the orca had left so much destruction around them that Mary decided to move out from their obliterated surroundings. After extracting her fist from Nikki, Mary pulled the beefy cetacean in her arms, knowing it would have been too much to ask her to walk right now. She looked around, marveling at how absolutely minuscule everything looked. Mountains were dwarfed by them. Entire forests looked like patches of grass one would casually step on in some muddy woods.

Being several hundred miles tall afforded the giantesses an incredible, all reaching view of the coastline of their state. "I'm all sweaty and dirty after all that, Nikki. How about a dip in the ocean?"

"Sure..." still panting, Nikki was having a hard time not simply going along with anything. Stomping down towards the sea, Mary hopped in with a big splash that washed over every beach city for dozens of miles. They became submerged for a moment during which Nikki's natural advantages allowed her extra mobility in spite of her exhaustion. Soon, she pulled Mary and herself up above until they were poking out up to their shoulders, with their breasts floating in front of them of course. "This is so much better than the showers."

"I know!" Mary relaxed, her arms and back resting against the coastline, "We're so massive already. Do you think we'll ever stop?"

As Nikki leaned in against Mary, she just rested her head on the dragoness' shoulder, sexual exhaustion creeping up on her. "I wouldn't mind outgrowing the entire fucking planet with you, Mary. But if by some chance this wears off... I'm expecting two dozen beefcakes by tomorrow." She said, starting to doze off into an adorable snoozing.

With a grin, Mary reached over to pet Nikki's head. They had come so far, but Mary agreed the growy effect had slowed down. She wondered if sex had made their expansion that much faster and resolved to test it... when Nikki woke up again. The whole world was theirs. It was going to be fun to test just how insignificant they could make their new toy become. But for now, Mary wanted to rest her eyes.

When next she awoke, she'd have to make sure to treat her new favorite customer to a new unforgettable experience.

The End.
