A sudden competition of physical strength prompts Sunset to test the endurance of her workout team

Sunset Shimmer is a big girl. Massive. Over 8 feet tall and with a bodybuilder's physique. She keeps herself in shape by hitting the gym daily. Today, she runs into her rival, who's arguably just as massive, and the two go head to head to decide, once and for all, which amazonian giantess is superior.

Endurance Training

“You know, Trixie can walk.”

Sunset chuckled as she strolled through the gym to the weight room, her “equipment” well in tow. Today had been a productive day for her. She was back on her diet after falling off in a bad way since her birthday the month before (she could never resist a good sundae, and with her size, she could easily eat gallons of ice cream), and she managed to beat her best time on her morning 10k run. Now, all that was left was strength training, and Sunset always felt best when she could end her day with a nice, hard weightlifting session.

“But then I couldn’t sling you around wherever I wanted,” said Sunset, easily clutching Trixie over her shoulder as if she weighed nothing at all. The magician herself was holding Sunset’s gym bag, and kept up a facade of annoyance with the way Sunset was manhandling her.

She wasn’t convincing anyone.

“Um… Sunny? You’re squeezing me a little too tight…” Sunset winced slightly, but loosened her grip on her other workout partner; while Trixie was over Sunset’s shoulder, the quiet, meek, oft-overlooked Wallflower Blush was cradled under Sunset’s other arm. Wallflower was quite a bit taller than Trixie, standing at about 5’2 without her slouch, and she was definitely curvier in just about every way. Even still, Sunset dwarfed her at over 8 feet, nearly 500 pounds of sheer power.

“Sorry, Wall. Not gonna lie, I kinda forgot that you were here,” said Sunset. “You know, you don’t have to come if you don’t want to. I can meet you back at my place later if that’d make you feel better.”

“And how come Trixie wasn’t given such an offer?” remarked Trixie. Sunset gripped Trixie a little tighter, giving her ass a firm, but gentle (or as gentle as an Amazonian could be) spank.

“Cause I left my sweat towel at home.”

“No, I’m okay,” said Wallflower. “I like watching you work out…”

“Why is that, hm?” teased Trixie, looking down from her perch and winking slyly at Wallflower. “Is it because you know Shimmer gets horny after lifting and she needs somewhere to put her cock?”

“No, Trix, that’s what your mouth is for.” Sunset swatted Trixie’s ass again as they approached the door to the weight room, smirking as she quivered, even letting out a tiny moan. “It’s the only thing big enough to shut you up.”

“C’mon, sis! Last set, you can do it!” Sunset groaned when she heard the voice, stopping to set down Wallflower and Trixie. For the first time that day, Trixie seemed concerned with something other than running her mouth, and she tried to place where she knew the voice from.

“That sounds familiar…” noted Trixie. Sunset tore off her hoodie, leaving her arms bare in her tank top. Although something serious was clearly going on, Trixie couldn’t help but gawk at Sunset’s size. Those arms, the biceps. Trixie knew that if Sunset had decided to flex her arm completely while she was still carrying her, she’d snap Trixie in half. Trixie bit her lip as she imagined Sunset tying her up like a pretzel, and she could feel herself getting wetter and wetter as time went on. Anyone who knew Trixie could tell quite obviously that it wasn’t Wallflower who tagged along to help Sunset cool down after her workout.

“Yeah, we know these three. Unfortunately,” sighed Sunset. With a shake of her head, she pushed open the doors and strode boldly into the room, refusing to back down from the incoming fight.

“Ugh. You.” Aria Blaze sat down her barbell, sitting up on the bench to meet Sunset’s gaze. She was flanked by her sisters, unsurprisingly, although she seemed to be the only one significantly unhappy to see Sunset. And, truth be told, Sunset didn’t much mind the other two. Sonata, who was more tits than brains (a lot more tits), was harmless, and Adagio seemed to be mature enough to leave well enough alone. Sunset did let her eyes linger on Adagio’s form for a second, her thick, meaty thighs and wide hips making Shimmer’s cock twitch to life in her sweatpants. After getting an eyeful of the decidedly thick Adagio, Sunset turned her attention to the real problem.

If it weren’t for Aria’s size, Sunset was sure their little rivalry would’ve fizzled out long ago. There was no way they were still mad about the Battle of the Bands, and it became clear soon after the two began their feud that this wasn’t about being defeated. No, this was about something far more important. This was a rivalry about who was the bigger, stronger Amazon.

Where height was concerned, Aria edged out Sunset by just a hair. If Sunset was 8’2, then Aria was 8’3 and a half. As for musculature, that was a bit more debatable. Aria was a bit thinner, leaner, but still with a figure that put most gym goers to shame. Her abs were the stuff of legend, a six pack so solid and well-defined that even Sunset found herself a teeny bit jealous, and she had a set of legs that could fell a tree with her thighs.

“Yeah, this is kinda my gym too, so…” Sunset gestured to a bench across from Aria. “I’m gonna do my workout and we’re not gonna do anything dumb. I just wanna lift, dude, so can we call a truce to this stupid thing we have going on?”

“Whatever. Nata, water.” Sonata grabbed a water bottle from her bag and twirled on the spot, handing it to her sister as if she were offering her the Holy Grail. “Thanks.”

“No prob, sis! And hiya, Sunny!” Sonata turned to Sunset and waved wildly. After a firm elbow to her soft, slightly pudgy belly, Adagio gave a half-hearted wave of her own. “ Who’re your friends?”

“Hey, Sony, Dagio,” said Sunset, stretching to prepare while Trixie went about setting up her station. “The short one is Trixie, and the one who’s trying to hide behind my thigh is Wallflower.” Sunset reached around her back and grabbed Wallflower around the back of the neck, plucking her off of her feet effortlessly. Wallflower let out a tiny yelp as Sunset swung her around to face the others. “Wallflower, say hello. They’re not gonna hurt you, probably.”

“Hello…” said Wallflower meekly.

“And Trixie will have you know, she is not short!” snapped Trixie. “Everyone seems short by comparison when you’re 8 feet tall, ya freak!”

“Dude, I’m pretty sure you can legally be considered a ‘little person’,” snorted Sunset.

“I’m taller,” grunted Aria, earning her a glare from Sunset. Aria rolled her eyes as she laid back down to continue her routine. “What? It’s true.”

“So what if you’re like an inch taller? My arms are bigger.” Sunset wasn’t sure why she was letting Aria get under her skin like this. Who cared who was bigger than who? Sunset had to admit it to herself that, even though she shouldn’t, she cared. She had gotten too used to being the biggest, strongest girl around that she wasn’t about to let Aria take her spot without a fight.

“My legs are bigger,” shot Aria.

“I squat more than you.”

“I run faster.”

“I bench more.”

“And she’s bigger in other ways, too,” noted Trixie with a smirk. She could feel her heart pick up at the glare she was receiving from Sunset. Trixie always found that an angry, riled up Sunset was always more fun in the long run. “Where it really counts.”

“Damn it, Trix!”

“Uh, wait, are we talking about dick?” asked Sonata. “Cause, like, no offense, Sunny, but there’s no way you’re bigger than Aria. She’s got, like, the fattest cock ever. It’s gotta be some kind of a record.”

“You’re not supposed to talk about your sister’s dick in public,” droned Adagio. Sonata shrugged, then poked Adagio’s belly, much to her elder sister’s visible annoyance.

“And you’re not supposed to be snacking after dark, but that muffin top says that you have been!” Adagio slapped Sonata’s hand away, glaring with enough raw fury to reduce grown men to ash. Naturally, Sonata just giggled and poked her again.

“Poke me again and no one will ever find your body.”

“Well, at least there’s one area we can all agree on,” remarked Trixie. “And that’s the fact that Sunset Shimmer clearly has a superior workout team!” Sonata gasped as if Trixie had deeply and profoundly offended her, pouting and turning her glare to Trixie.

“How do you figure? Me and Dagi are the best workout team ever!” said Sonata defiantly. “How could you ever be better than us?”

“Clearly, Adagio is a cold-blooded bitch who doesn’t care to be here and you never shut up.” Trixie flipped her hair as she laughed derisively. “Whereas on our side we have Wallflower, who is the spitting image of enthusiasm, and me! The Great Trixie could never annoy anyone!”

“Holy shit, you’re an idiot…” groaned Sunset, pinching the bridge of her nose.

“Eh… She’s got a point, honestly,” admitted Aria. “Dag makes it seem like the end of the world whenever I go to the gym, even though no one is making her come, and there’s not enough workout music in the world to drown out the dumbass when she gets going.” She set her barbell down on the rack, sitting up to better see the collection of morons before her. “Do you normally just stand there like a jackass, or do you actually work out when you’re here?”

“Well, now that Trixie is done stirring the pot and trying to get under my skin so that I use her to unwind, I think I can actually do the one thing that I even came here to do.” Sunset approached her bench press, sliding the last few weight plates onto her barbell, glancing curiously over to Aria. “How much do you bench?”

“575,” said Aria with a shrug. “Could probably go for more, but today has been shitty, so I don’t feel like it.”

“Hm. Guess that means I’m doing 600, then.”

“Fuck you. Sonata, put another 25 on.”

Sunset rolled her eyes as she laid herself down, hands on her weights and waiting for her partners to get into position. When Trixie and Wallflower were in position near Sunset’s head, the amazon went to work. Even though they had seen it dozens of times by now, Wallflower and Trixie couldn’t help but admire the tensing of Sunset’s arms while she benched, her perfect musculature bulging every time she brought the bar to her chest and back up. Her body was ridiculous, every muscle bristling with enough power to put mere mortals to shame.

Aria seemed to be more than just a mere mortal as she began her reps, lifting just as much as Sunset. In fact, Aria’s reps were a bit quicker, no doubt to catch up to her rival. It wasn’t long before the two had plateaued, matching speed and neither showing signs of stopping. Soon after, when things were getting just a bit too quiet, Sunset and Aria’s respective cheerleaders decided to make their presence known.

“Push it, Shimmer! Come on, this is light work!” barked Trixie.

“This is easy for you, sis! Come on, every rep of every set!” Sonata glared over at Trixie, locking eyes with the magician. An almost visible spark ignited between the two, neither of them willing to admit that their girl was the inferior lifter.

“Slowing down, Shimmer?" grunted Aria.

"Not on your life." Sunset knew she shouldn't be playing into this madness, but she couldn't help herself. She was naturally competitive, especially when her strength was concerned, and she couldn't live with the idea that someone was stronger than her, even for a second. "I can do this all night."

"Are you still talking about lifting, Sunset?" chuckled Trixie, crouching down beside her. "Or something more pressing?"

"I'll press you, if you don't shut up," snapped Sunset. When Trixie giggled, Sunset let out a snarl, doubling her efforts to outpace her rival. "That's not what I meant, idiot."

"This is getting us nowhere," huffed Aria. She was beginning to sweat quite a bit, her strong, sturdy arms glistening with the results of her work out. "Break?"

"Well, I was just getting started," said Sunset, though this was a bit of a lie. 570 pounds was the most that she had ever benched, and, while she was certain she could lift more, this was quickly approaching her limit. "But I'm good for a break if you are."

"Fine. Call this a draw." Aria racked her weights, as did Sunset, and sat up for a quick breather. She gestured for Sonata, who quickly delivered a water bottle and a clean towel for her sister. "Thanks."

"Should Trixie fetch a towel as well?" asked Trixie. Sunset sighed, clutching her head in frustration.

"I kinda wasn't kidding about leaving the towel at home…" sighed Sunset. "I didn't think there'd be anyone else here…"

"And what, you thought Trixie would just tongue bathe your balls in the middle of the gym?"

"I thought I wasn't going to give you a choice."

"Ha! See, that's proof that our team is better!" declared Sonata. "Aria would never need to convince me to do that!"

"Again, not something you should be mentioning about your sister in public," said Adagio.

"Not like you're any better. You like sweaty Ari more than I do!"

"Absolutely not."

"I've got pictures of you with my cock in your throat that suggest otherwise," chimed Aria. Adagio shot her another one of her trademark murder-glares, which only earned a shrug from her sister. "What? Shimmer has her post-workout fucktoys and I have mine. What does she care about what we do when I'm done with my set?"

"For the record, I don't," said Sunset. "I just like to come here to fool around with these two because I don't want to fuck up my apartment while throwing Trixie around."

"And Trixie can't help but notice that my partner is strong enough to throw around a dozen of me!" said Trixie. "Much stronger than your sister!"

"Oh, that does it! Here, chew on this!" Sonata dove into their gym bag and, after a brief minute of searching, emerged with a large ceramic dinner plate, of all things. Before Sunset's team could formulate a question, Sonata took the plate and flung it as hard as she could, releasing it and letting the plate fly directly at Aria.

The dish broke upon impact with Aria's incredible abs, shattering into countless fragments and dancing to the ground to the visible shock of Wallflower and Trixie (although Trixie did at least make a poor attempt at concealing it). Aria rolled her eyes, brushing off the dust of the ruined plate from her midsection.

"Must you do that damn party trick every day?" growled Adagio. "It makes a mess everywhere, and we're running out of plates at home."

"Not bad, Blaze. That's about as hard as it gets," said Sunset with a small nod. Aria tilted her head at Sunset, as if not entirely sure how to react to a genuine, unsarcastic, unironic compliment from her rival.

"Thanks. You don't look too bad in the core, yourself," she said slowly, as if the words might cause her physical pain.

"Sunset. Do the thing." said Trixie, finally snapping back from her stupor.

"I'm gonna regret asking," sighed Sunset. "But what thing?" Trixie dove into her own gym bag, emerging with a giant long-sleeved t-shirt, one custom made to actually fit someone as tall as Sunset. As soon as she saw it, Sunset groaned, but slipped the garment on over her head nevertheless. "Fine, but you owe me for this one."

Sunset straightened her shirt, taking in a deep breath to prepare herself. After a quick little stretch and a breather, Sunset extended her arms out and quickly flexed both of her biceps. Her physique bulged against her clothing, straining the fibers of her shirt. Sunset glanced to Trixie, rolling her eyes at the rabid nodding she got in response, then curled her arms downwards, keeping her arms flexed as her fists met near her stomach.

The sound of shredding, ripping fabric filled the room as Sunset's shirt tore against the awesome force of her thick, solid biceps. She effectively exploded out of her top, the tattered rags of her t-shirt dancing to the ground while the group watched in awe.

"Oh shit," whispered Sonata. "That was kinda hot…"

"Kinda? I can't imagine anything hotter," said Trixie, nudging Sonata with her elbow. "Trixie thinks she might need to change her panties."

"Well. Fuck. I think that matches my plate trick," said Aria. "So we're still tied."

"It doesn't have to be a contest," noted Sunset. "We could just be workout buds." Aria looked at her as if Sunset had sprouted a second head before letting out a sigh and giving a noncommittal shrug.

"Eh. Whatevs. Sucks that we don't have a definitive winner, though. Makes this whole thing feel kinda pointless if we can't settle on who's better."

"I have an idea." Suddenly, all eyes were on Wallflower, who seemed to have regretted breaking her silence. She shrunk down slightly, cowering under the weight of the gazes she had summoned onto her. "Well… if you two are, you know, evenly matched, maybe it could come down to us. Your workout partners."

"What do you have in mind, Wally?" asked Sunset. Wallflower instinctively tried to retreat from the sudden attention, stopping only when Sunset grabbed her sweater by the collar and yanked her up off the ground, depositing her gently in front of her. "Come on, Wall, you have to quit running away from everything. You’re worse than Fluttershy."

"Right, sorry. But, my idea was an endurance contest of sorts."

"Me and Shimmer are gonna be evenly matched there, too," noted Aria.

"Right, but… I didn't mean your endurance." Wallflower blushed bright red, her gaze easily traced to Sunset's sweating, toned, statuesque physique. "Maybe test how long your partners can, er… Last…"

"I knew it! You want it just as bad as I do, you slut!" shot Trixie. Sunset growled, grabbing Trixie around the back of the neck with her massive paw, yanking her up with a tight, powerful grip. "W-what are you gonna do, Shim? Hurt me?"

"You'd just love that, wouldn't you?" said Sunset. Trixie nodded, biting her lip in anticipation, letting out a disappointed sigh when Sunset lowered her back to the ground, entirely safe and unharmed. "Be good and I'll hurt you tons when we get home."

"I'll hold you to that."

"So, what? We fuck our girls until they tap out?" Aria shrugged, tossing her water down to the floor and wiping herself down with her towel. "Alright, whatever. We're down."

"Excuse me? You can't just volunteer me for this!" said Adagio, scowling at her sister. "Just because I fed your ego once or twice doesn't mean I want anything to do with you or your sweaty, disgusting cock. Or your hot, heavy balls, or your big, strong arms, or…" Adagio shook herself gently as she realized that her hands had snuck its way into her pants, and she quickly swiped her fingers away from her cunt. "Shut up…"

"Well, Trixie isn't gonna let me leave here without dicking her down, so…" Sunset leaned herself back slightly and spread her legs to show the thick bulge against her thigh. "There, you win. Have at it, ya greedy slut." Trixie grinned, diving between Sunset's legs and grabbing at her workout pants tightly. With a sly grin, Trixie ripped the enchanted fabric until Sunset's massive cock sprung free, bursting out and slapping Trixie under the chin with enough force to knock her back onto her butt. "God damn it, Trixie! I only have like one pair of magic pants left!"

"Sorry, Trixie can't help herself…" Trixie grabbed Sunset's shaft, still in awe at the size and heft of it, and gave it a slow, savoring lick. "Wallflower, get over here and help Trixie make it up to Sunny." Wallflower nodded, then scrambled over to assist her partner. There was a lot of ground to cover, but the two were up to the herculean task before them. While Wallflower was quiet and reserved in her speech and demeanor, she threw all that out the window when Sunset’s cock was in front of her; she licked and kissed up and down the length of Sunset’s shaft with just as much enthusiasm as Trixie, if not more.

“Hey! No fair, you got a head start! Come on, Dagi, we gotta catch up!” Sonata grabbed her sister by the wrist and dragged her to a stop in front of Aria. “Hurry! We’re gonna fall behind!”

“But that’s not how the contest…” Aria began to argue about how rushing to catch up might actually put them at a disadvantage in this particular contest, but decided against it when Sonata grabbed her bulge and came to the conclusion that she may as well go along with it. “Whatever. Just don’t rip my pants, or else.”

“Okay!” Sonata saluted her sister before quickly rolling down Aria’s workout pants. Sunset glanced past her own impressive equipment (which was much easier said than done) to get a look at Aria’s. She had never seen Aria’s cock before, and she was curious to see how they compared. It was another close comparison, with Aria’s heavy purple cock beating out Sunset in terms of girth by a mere inch and a half across. Conversely, she was a bit shorter than Sunset’s, coming to a stop about two inches before Sunset. Sunset was liable to call that another close tie. “Come on, Dagi, you know you want to…”

“Fine. Just don’t get it in your head that I’m actually enjoying this,” snorted Adagio. “I just want out of this stuffy gym as soon as possible.”

“Well, you can go, if you want,” said Aria with a smirk. “I only really need one of you for this challenge or whatever you call it, and I don’t wanna make you do something you don’t want to do. Bow out, if you really don’t want to screw around.” Aria may as well have been speaking to a brick wall, because Adagio paid her little attention as she went about removing her top to allow her big, roung, squishy tits to breathe.

“I already said I’d do it…” Adagio elbowed Sonata out of the way, wrapping her tits around Aria’s thick, throbbing cock. “Hurry up, Sonata! This was your idea in the first place!”

“Ooh, good thinking, Dagi!” Sonata quickly pulled her top off, giving her own breasts a firm squeeze. If Adagio’s rack was big, then Sonata’s were excessive; easily bigger than her head, and with cleavage so deep that Sonata had lost her keys in it on more than one occasion. She put the enemy team to shame in the shadow of her sizeable funbags, and Sonata made good use of them by pushing them firmly against Adagio’s, swallowing the girth of their sister’s cock with their tits. With a measured practice, an almost intrinsic sense of rhythm and timing, the two wrapped their arms around their breasts and brought them up and down the length of Aria’s sweaty, throbbing rod.

“Grrr… No fair! It’s not Trixie’s fault her breasts haven’t developed yet!” complained Trixie.

“Dude, I think that ship has sailed,” said Sunset. Trixie frowned, and Sunset used her passive hand to pat her on the head like a pet. “Don’t let that bug you, though. You and Wally have other talents.”

“Hm… You’re right!” Trixie turned and pointed at her partner, a blazing inferno in her eyes. “Wallflower, take off your pants!”

“Uh… Why?” asked Wallflower, pausing with her hands at her waistband. “I, uh… I’m kinda nervous about… That.”

“You may pale in comparison to the Great Trixie as far as looks and sex appeal goes, but you do have some delectable thighs.” Trixie, impatient as ever, leapt onto Wallflower and all but ripped her pants off of her body. To her surprise, and great amusement, the shy and reserved Wallflower had chosen today to go without panties, making their job a bit easier. “How naughty…”

“Well, if that’s what we’re doing…” Sunset took a brief moment to ignore typical gym safety and lifted the barbell just a bit behind her and tossed it onto the ground so she could lean back without smacking her neck into her weights. “There. That should be more comfortable. Go for it.”

Wallflower nodded, then leapt into position. She straddled Sunset, feeling the thick, meaty pole throb against her hot cunt, before squeezing her legs together and sandwiching Sunset with two thick, juicy thighs. Wallflower grinded up and down Sunset, feeling her pussy get wetter, hotter, hornier with every thrust. Not content to just sit and watch, Trixie slid beneath the two, diving her head between Sunset’s legs and (attempting to) wrap her lips around one of Sunset’s hot, heavy, sweaty balls.

All the while, the two Amazons glared at each other from across the room, examining the enemy’s techniques. Though neither would ever admit it, they were both very impressed with the other team. The rhythm of the sisters was impeccable, and Aria couldn’t overlook the enthusiasm and craftiness of Trixie and Wallflower. The two weightlifters shared a look, and then a small nod, confirming that they were on the same page.

Time to kick things up a notch.

“Hey, Wally,” said Sunset, her voice dipping down, her tone breathy and heavy. She was starting to care less about the contest and more about getting her rocks off. “How’s your jaw feeling?”

“Erm… Better than last week. I’ve been doing those jaw stretches that my doctor told me to do, and I think I’ve really loosened up a bit,” said Wallflower, her heart beating like a drum. “W-why do you ask?”

“Sorry about that, by the way. I didn’t think I could hurt you that bad. That said… You may need to make another appointment with that doctor.”

Before Wallflower could process the implications of that, Sunset yanked her up with one hand and turned her upside down, lowering Wallflower down until her nose was pressed against Sunset’s shaft. Sunset stood up, keeping a hold of Wallflower by her ankle, and dangled her for a moment before she aggressively shoved her length past Wallflower’s lips. As if by some reflex, Wallflower let her jaw go slack, her throat relax, and ran her tongue around Sunset’s cock. She savored the salty, sweaty, masculine taste of Sunset’s meat for a moment before Sunset wrapped an arm around Wallflower’s middle to hold her steady and pound her hips forward. Trixie watched from her seated position below Wallflower’s head, teeming with envy at the wet, sloppy sound of her friend getting her throat mercilessly fucked.

“Lucky bitch,” pouted Trixie, crossing her arms over her chest.

“Get back to washing my balls and I’ll do you next,” promised Sunset. Trixie glanced up to Sunset and, when she confirmed that she meant what she said, went right back to tonguing Sunset’s heavy sack, worshipping the fat balls with sloppy kisses and even sloppier licks.

“I suppose that means I have to suck you off now?” scoffed Adagio.

“Well, actually, I could do it if—” Sonata may have gotten more out if not for how Adagio suddenly shoved her out of the way, sending the brainless bimbo tumbling to the ground.

“Truly, I do so much for this family. Such a heavy burden to bear…”

And, with that, Adagio went to work. Whereas Wallflower did her job by simply sitting there and letting Sunset use her throat, Adagio employed a different strategy; She licked around the tip of Aria’s cock before wrapping her thick, soft, dick-sucking lips around the massive member and diving in. She used one hand to hold Aria’s cock, stroking the length that wasn’t able to fit in her mouth yet (which, given Aria’s size, was most of it), and used the other hand to gently squeeze and caress her sister’s sizable nuts. Adagio let out a grunt that was lost on Sunset and her team, but apparently made perfect sense to Sonata, who quickly leapt into action. She slid in behind Adagio and pulled the hair that was beginning to stray into her eyes back while Adagio went to town.

“Fuck, that’s what I needed…” groaned Aria. She leaned back onto her elbows, enjoying the professional-quality blowjob that she was receiving. “You know, for someone who claims to never suck dick, not even the dudes you date, you’re pretty fucking good at it.” Adagio removed her hand from Aria’s balls for just long enough to give her sister the finger. “Cute. If you’re gonna be like that, maybe I’ll just use Sonata’s mouth.”

“Hmmmn!” Adagio wasn’t able to speak on account of the thick, juicy cock in her mouth, but the energy and desperation in her voice made her refusal clear. She glowered at Aria’s smug grin before quietly muttering something that was equally difficult to make out. “Ahmschry…”

“Don’t talk with your mouth full, princess.” Adagio bloomed bright red, but nonetheless pulled Aria’s cock from her mouth with a wet, sloppy pop!

“I said… I’m sorry…” grumbled Adagio. “There. Happy?”

“I’ll be happy when my dick is touching your tonsils.” After a quick roll of the eyes, Adagio dove right back onto Aria’s cock, taking it even deeper than before. She slurped all the way down to the halfway point with ease, and from there she had to slowly force herself down to push more and more of Aria’s hot, musky dick into her throat. “That’s right, that’s what I like… How you doing over there, Shimmer? Ready to give up?”

“Wouldn’t count on it,” grunted Sunset, quickening her already vicious thrusts. Before, she stopped a little before halfway, but now she went all out, burying every inch of her length into Wallflower’s quivering throat. Wallflower herself was barely conscious, her eyes rolling back in her head and her body quivering with every relentless buck of Sunset’s hips. Her cunt dripped, gravity carrying her juices down her torso until she could almost taste herself. “But… Round one might be ending soon…”

“Damn… Me too…” grunted Aria. “Dag, get ready…”

“Wally, can you hear me?” Wallflower gave a weak, trembling thumbs-up, bringing a grin to Sunset’s face. “Well, you’re doing a really, really good job. I’m gonna cum soon…”

Wallflower let out a weak grunt of a moan, which Sunset elected to take as confirmation that she was ready. Sunset pounded her hips forward, someone going harder and faster than before. Never to be accused of not doing her part, Trixie quickened her pace as well. She could almost feel the cum gurgling in Sunset’s balls, just dying to come out, and she would do everything she could to free it. Once again, Sunset and Aria became more concerned with each other than anything, staring down their rival to see who would break first. As the seconds ticked on, the pressure building, it became very clear that regardless of who came first, their opponent would be right behind them.

Sunset slammed her hips forward, pressing Wallflowers face against her balls as her cock erupted, sending hot, thick ropes of cum directly down (or up, on account of her position) Wallflower’s gullet. Though she claimed to be ready, and even believed herself to be, that couldn’t have been farther from the truth; Wallflower choked and gagged as she fruitlessly tried to swallow the ridiculous amount of thick, creamy goo entering her body. She tried her best to keep up, but it was impossible, and cum was soon leaking out of the corners of her mouth, even spewing out of her nostrils, and dripping down onto Trixie. Sunset wasn’t sure when, but she was certain that Wallflower had passed out at some point, and so she pulled her cock free causing the cum that Wallflower had failed to swallow to spill out, once again directly onto Trixie’s head. Slowly and gently, the giantess laid her used toy on the ground to recover.

Almost simultaneously, Adagio felt her sister tense, Aria’s hips go up and her cock pulsating as she came. Aria produced just as much cum as her rival, if not more, but Adagio fared much better than Wallflower; She gulped down each thick load, dutifully swallowing each new mouthful of spunk as soon as she could. Unfortunately, she couldn’t keep up the pace, her eyes rolling back as she gave one last-ditch effort to get it all down. Sonata jumped forward to help, just for Adagio to slap her away and try to claim all of the cum for herself. She could feel her already plump belly swell and fill with cum, her head going light and her vision going blurry both from lack of oxygen and from the almost comical amount of spunk she was attempting to consume. Finally, Adagio could take no more, and fell back from Aria’s cock, just in time to catch the last few ropes of cum with her face and tongue.

“Dagi, are you okay?” asked Sonata.

“I’m… perfectly… fine...” Adagio licked the salty, addictive cum from her lips, taking a moment to savor it before slumping over onto her back. “Wake me up… When it’s my turn…”

And, with that, both Team Aria and Team Sunset were done one member each.

“Could you have moved so that you wouldn’t coat me in cum?” asked Trixie, trying to use her fingers to rake the seed from her matted, once-luxurious silver hair.

“Oh, please. You’d bathe in my cum if I let you,” shot Sunset. Trixie pouted, then slowly brought her hand to her mouth to lick the cum from her fingers.

“Just think about how soft my skin would be…”

“Well, shit. Both down one,” said Aria. “Now it comes down to Sonata and that midget.”

“Trixie is not short!” snapped Trixie. “She is a perfectly reasonable height, and you two are just freaks!”

"Shut up and get those tights off, short-stack," ordered Sunset. "I'm ready for more." Trixie's heart skipped a beat, and she quickly went about pulling off her midnight blue nylons. Much like Wallflower, Trixie was going commando. That said, her juicy cunt was so wet that Wallflower seemed like a desert by comparison. "No panties either? Now who's the greedy, naughty slut?"

"Trixie never denied that for a second." Trixie clambered onto Sunset, grinding her cunt against Sunset's shaft. "Now hurry up and fuck me."

"I wanna get fucked, too!" Sonata quickly pulled off her skirt, modelling her juicy bubble butt in her pretty pink thong. "C'mon, Ari! Give it to me."

"Aren't you forgetting something?" droned Aria. Sonata tilted her head in confusion, until Aria pointed at her still-clothed cunt. "Panties, dummy."

"Oh yeah!" Sonata wiggled out of her thong and, to Sunset's surprise and confusion, stuffed the cloth into her mouth. "Rhmdy!"

"What's that about?" asked Sunset, using just one hand and minimal effort to keep Trixie from greedily impaling herself onto Sunset.

"She literally never shuts the hell up. This is the only thing that makes her bearable." Aria chuckled as she ran a finger against her sister's twat, smirking as Sonata shuddered with delight. "Well, that, and her pussy ain't bad, either. Ready to go, airhead?"

Sonata nodded excitedly, cheering into her improvised gag when Aria yanked her up, holding Sonata around her petite, supermodel-esque, hourglass waist with just one hand. Sunset narrowed her eyes, taking this display as a challenge she had to meet, which she did quite easily. Despite Trixie’s insistence that she was normal-sized, Sunset was able to fling her around and manhandle her even easier than Aria could with Sonata.

Sunset slid her cock forward, intentionally missing Trixie’s cunt and sliding up her tiny torso until her tip was pressed against the magician’s chin. Trixie loved this, a visual demonstration of the truly stupid size of the cock that was about to absolutely demolish her. She trembled as she imagined the massive organ inside her, her pussy so hot and ready that even just feeling Sunset’s shaft against her lower lips was almost enough to make her cum on the spot. Finally having had her fill of teasing Trixie, Sunset finally pushed her way into Trixie’s pussy.

Trixie must’ve been spread by Sunset’s cock a hundred times by this point, and yet she still couldn’t prepare for the typhoon of feelings. She felt like she was being slowly torn in half, Sunset’s dick filling her in a way that nothing else could ever possibly achieve. Her brain felt like it was melting, her legs turning to jelly, and the only noise she found herself capable of making was a long, low moan. Sunset bit her lip at how remarkably tight Trixie was, even after taking her full length and girth so many times. She took that as a challenge, and so she sought to truly ruin Trixie, bucking her hips up and slamming every last inch of futa cock into Trixie’s tiny, frail little body.

Aria was matching Sunset tit for tat on her side of the gym, sliding into Sonata’s excited pussy with very little reservations. Whereas dick seemed to be the only thing capable of shutting Trixie up for any extended period of time, it seemed to have quite the opposite effect on Sonata, who squealed and screamed in delight with every rough, unforgiving introduction of her hips to her sister’s.

Sunset dropped down to the ground, laying Trixie down on her belly and almost flattening herself down onto the tiny girl. Trixie could feel Sunset’s strong, pounding, booming heartbeat in her chest, and felt her own heart nearly stop when she felt Sunset’s arms slowly wrap around her neck. Trixie gasped, able to do little more than that before Sunset went right back to pistoning her hips forward, slamming into Trixie while pinning her down with a firm, unbreaking headlock. Trixie couldn’t contain herself any longer, her eyes rolling back in her head as she came hard on Sunset’s cock.

“There’s a good girl,” grunted Sunset, giving Trixie’s quaking, trembling body no rest or respite. “Don’t give up on me, now. This is what you wanted, right? You wanted for me to wreck you in the middle of the gym?”

“Y-yes…” breathed Trixie. “Please… More…”

Sunset let out a determined grunt before giving Trixie just what she asked for; She tightened her grasp around Trixie’s neck, lowering more of her awesome weight onto Trixie’s prone body, each violent buck of her hips threatening to flatten the magician. Sunset grit her teeth, groaning at just how good, how tight a tiny girl like Trixie felt. She glanced up to see her competition, grinning slightly at how focused Aria was.

She had dropped Sonata down onto the bench, keeping her head down with one big, strong, meaty hand and her ass up with the other. For the first time since she arrived in the gym, Aria was paying her rival no mind. Currently, the only thing that mattered to her was Sonata’s tight, hot hole and how she would spread it to it’s breaking point. It seemed like that might be sooner rather than later, as evidenced by the crazed, almost psychotic ecstasy spread across Sonata’s features. She clutched her head, as if unsure what to do with her hands, and let out her shrillest, highest shriek so far.

“Fuck, cumming already?” scoffed Aria. Her breath caught in her chest as she felt Sonata’s cunt clamp down on her cock, begging it for cum. “I don’t think I’m far behind, actually…”

“I’m in the same camp,” grunted Sunset. She snaked her arm under Trixie and grabbed her by the belly, feeling the bulge of her cock through Trixie’s midsection as she pulled her up slightly. “I’m about ready to fill you up, Trix. You good?”

“C-cum… Cum…” That was all Trixie could really manage, and seemed to be more than enough for Sunset; She slammed her hips relentlessly into Trixie, shaking her entire body with her forceful thrusts. Aria matched her speed, if not surpassed it, slamming into her sister’s cunt with reckless abandon. She gritted her teeth, unable to hold off much longer.

Finally, Aria groaned like a savage beast, her dick pulsating and depositing thick ropes of fun into Sonata's womb. A moan escaped Sonata as she felt load after load flood her insides, filling her fit to burst. Aria pulled out, stroking out the last few loads directly onto Sonata’s back, coating her both inside and out with sticky white.

Sunset lasted just a split second longer, and she bottomed out in Trixie’s small, impossibly tight body as she came. Each load was like a tidal wave to Trixie, filling her and causing her belly to inflate slightly from the ridiculous amount of cream it tried to contain. Try as she might, Trixie simply couldn’t hold it all, and cum gushed from her spread, gaped cunt as Sunset pulled out, wiping the sweat from her brow.

“Well, that was fun,” said Sunset, pulling herself up and onto her bench to allow Trixie a chance to recuperate. She surveyed the scene for a moment, noting how Trixie wasn’t moving much, save for her ragged breaths and occasional twitches. “Uh… I think I broke mine.”

“Same here.” Aria rolled Sonata off of the bench, dropping her on top of the sleeping body of Adagio. “This didn’t really prove anything, huh?”

“Nope.”

“Do you care?”

“Nope.” Sunset leaned over to her gym bag and produced two bottles of blue sports drink, one of which she tossed to Aria. “This was always a dumb contest that didn’t matter, but at least we had some fun. And, for what it’s worth, I can admit that you’re pretty impressive.”

“Thanks. You kept pace with me, which isn’t something most people can do. You even started to outshine be a couple times. So I guess we’ll never really know which of us is more athletic, if there even is one that’s better.” Aria looked around at the four well-fucked, cum-covered, unconscious girls on the floor, each of them laying in a puddle of fluids. “You know, we probably shouldn’t have done this in the gym. We’re gonna get banned.”

“Ban us? They sure can try.” Sunset and Aria shared a grin, then a toast as they popped open their drinks and took a much-needed refresher. “So. What now?”

“I guess we’re friends now, or whatever,” said Aria with a shrug. “Short term, though… Wanna switch? I kinda like the short one.” Sunset glanced down at Trixie, the loudmouth slut who was more than willing to cause some trouble if it would end with her getting tossed around and fucked like a cheap sextoy. Even though Sunset found her incredibly annoying at times, she’d be lying if she didn’t feel at least a but possessive of the tiny magician, and that went doubly so for the shy, meek, vulnerable Wallflower.

That said, she hadn’t been able to take her eyes off of Adagio’s thick, meaty body for quite some time.

“Sure. I’m game. Just remember that I’m only letting you borrow her.” Sunset flashed a grin. “Trixie’s mine, and I don’t want anyone to forget it.”

Aria nodded her understanding, feeling much the same sentiment, then crossed the room to scoop up her new temporary fuck toys. Even though they were bogged down with cum and dead weight, Aria was able to hoist them up over her shoulders very easily. Much the same, Sunset struggled to get a good grip on the Siren sisters, but, when she did, managed to fireman carry them with minimal effort.

“I’ve got a ton of room to mess around in at my place, if you wanna come with,” offered Aria. “We can go a few rounds, maybe order some food, and…”

Sunset wondered why Aria had trailed off, until she traced Aria’s gaze to the door. Standing in the doorway was two girls that they were very familiar with, one of them incredibly enthused and the other attempting to melt through the floor.

“Hey, Pinks. Shy,” sighed Sunset. “Didn’t hear you come in. Did you—”

“Did we see you dick Trixie and Wallflower into a coma?” said Pinkie with a manic grin. “Uh, doy. It was flipping awesome!”

“It was… something, alright,” said Fluttershy quietly.

“Come on, Flutts, I know you liked seeing that as much as I did. I just got one question for the both of you!” In a flash, Pinkie was somehow between the two giantesses, gently nudging them with her elbow. “When’s it gonna be our turn, huh?”

Aria and Sunset shared a look of confusion, then finally shrugged their shoulders in defeat. Aria scooped up Pinkie, flinging her over her shoulder much to her satisfaction, while Sunset collected Fluttershy and added her to the growing pile of girls on her back.

“I get first go on them,” said Sunset. “They’re my friends.”

“You can keep the skinny one, but we’re gonna have to arm wrestle or something for this.” Aria slapped “this” firmly, which just so happened to be Pinkie Pie’s thick, wide, juicy ass. Pinkie giggled as she was carried away, wiggling her hips in excitement.

“See, Shy? I told you hitting the gym would be great!” Pinkie glanced over to Sunset, who seemed to be actively fighting back a snicker. “So, Sunny, what’s our first workout gonna be?” Sunset pursed her lips, thinking things over for a bit. When the weight of the unconscious girls on her back registered in her mind, she gave a cheshire grin and followed Aria out of the gym.

“Well, first thing’s first, we need to work on your endurance.”
