Chapter 1 - Defeat.

 It was exactly midnight when Yang entered the gym at Beacon. The whole place was empty now, lights off - this was the meeting spot chosen. Yang looked up at the windows in the hall and saw the starlit sky, wistfully wishing she were back in her room. 

 The sound of a door slamming closed echoed all the way to her ears - Yang kept her eyes set on the moon. I could be relaxing right now. Approaching footsteps sounded louder and louder till she finally heard: “Glad to see you came.” 

 Yang turned slowly and saw Cardin standing with a backpack hanging from his fingers. His muscular arms were inked out in the moonlit hall. “What?” He grinned. “Cat got your tongue?”

“Let’s just get this over with,” she said with a sigh. 

 The other day, Yang had made the mistake of accepting Cardin’s challenge in a series of physical feats. It seemed unlikely that a beefy guy like that would win given the dexterity required for some of them. She figured it would be a done deal that she could put him in his place. Unfortunately, she lost; but Cardin still wanted to get his ‘reward’, which was some time alone with Yang. As much as she downplayed coming to see him to her friends, a bet was still a bet. If he tried anything she was going to teach him a lesson.

 Cardin threw the backpack into her arms and went to turn on the lights. “Check the training gear I got you. I know you’re going to love it.” 

 Yang unzipped it and looked inside. There was a cap along with a few articles of clothing. As the lights came on, Yang took out the sports bra and held it in her hands. The thing was so tiny that it barely would’ve covered her L-sized cups. Does he not realize how big my chest is? I guess I’ve been doing a good job of hiding it…

 Cardin returned and crossed his arms. “Well? What are you waiting for?”

“You don’t seriously want me to wear these, do you?”

“Listen, you lost a bet!” he reminded her with an imposing tone. “Stop being so difficult and do as you’re told.” 

 Annoyed, Yang stuffed the sports bra back into the bag. “Fine. But you’re going to have to wait. There’s no way I’m changing in front of you.” 

 The girls changing room was open and that was where Yang went. She stripped out of her own clothes then rolled up the shorts Cardin brought. Yang tried to stretch them out as much as she could, but her bubble butt so round and plump that it was difficult to get the fabric to cover up the entirety of her ass. The moment Yang bent over to pick up the bra from the backpack, she could feel the shorts rising all the way up to leave most of her ass and even her lower pussy lips exposed. Blushing, she pulled them back down. This guy! How small does he think I am?~

 The shorts were bad enough but the bra was even worse. Yang spent a few minutes trying to fit her plushy boobage into the fabric, but the tiny sports bra barely covered her nipples. This is made for C cups at most…

 A loud knock came at the door. “Yang! Ar you done yet? Hurry up, we don’t have all night.”

 Yang tried to pull the bra down over the undersides of her huge tits. “This bra doesn’t work for me! It’s too small.”

“You’re going to put it on or I’ll come in there to put it on you myself.” 

 At a loss, Yang observed herself in the mirror and did her best to hide her nipples though the lower part of her areolas remained exposed. The undersides of her boobs were left hanging out altogether, but at least the bra was so tight that there was no way her boobs were going to fall out somehow. 

 She was about to try on the cap when Cardin slammed the door open and came in. “You’re still not done?”

“Don’t just walk in on me, you creep. I could’ve still been getting dressed!”

 Cardin snorted derisively and took a stance of total superiority. “And? You think I want to see that body of yours? Look at your big ass and those huge tits. You look like a cow.” He grabbed the cap from the backpack and tossed it to her. “Put your hair in a ponytail. I don’t want it to get in the way.” 

 Sighing, Yang obeyed and stood before him in the full outfit, ponytail dangling out the back of the cap and tight sports bra stretching over her tits. Her hand kept going at her butt to pull the shorts over cheeks.

“I guess we should get started,” said Cardin. “Let’s go.” 

 The two went out in the hall together. They stretched for a time to warm-up, then Cardin started doing jumping-jacks and told her to follow his lead. Yang did her best though her huge breasts were swinging all over the place and shifting the balance of her body till she stumbled backwards.  

 Cardin laughed. “You can’t even exercise? Look, I’ll make you a deal. How about this: we’ll do a squatting match and see who wins. If you win, I’ll let you go back and you can forget the whole thing. And if I win, then we’re going to have to go for a more ‘personal’ style training, because this clearly isn’t working out.”

“Personal training?” asked Yang suspiciously. “And what exactly does that entail?”

“Just, uh, you know. Some cooperation in doing the exercises.” He smirked daringly. “Come on, what do you say? I mean I’ve seen your ass. There’s no way you’d fail at squatting, right?”

 That was true enough. Yang might not have had the strongest arms, but she was confident in her legs and her lower body. Meanwhile Cardin was all brute strength and arms. It was how he won over her too. He’s underestimating me.

“Have it your way,” said Yang with a confident smirk of her own. “Let’s do it. But I’ll set up the rules so there’s no funny business. We both do squats at the same pace, counting together, without holding onto anything. The first one to topple over wins.”

“That’s gonna take a while.”

“Aww, scared you’re lacking endurance?” Yang narrowed her eyes with pride. “Takes more than brute strength to win. You wanted this. So let’s go.” 

 The two got in position, opposite of one another but at enough distance. Yang was worried that his eyes would be going over her body, but he seemed surprisingly uninterested. Instead he just locked his gaze with her as if they were two predators challenging one another. 

“Ready?” said Yang. “Get set. Go! One… Two… Three…” 

“I’m so glad I can look at your tits as you work out,” said Cardin as they started. 

“Four… Five…” Yang tried to ignore what he said, but it was so sudden that her mind reeled. Was he actually getting turned on by this? Just ignore him and focus.

“I’ve wanted to fuck your brains out for a long time. It’s such a shame you let those big tits go to waste. You just need to be taught a lesson.”

“Shut up! Six… Seven…”

“Why, is it bothering you? Distracting?”

“Eight… Nine…”

“Want me to take out my dick?” 

 His words were distracting! Why did he keep speaking? “Shut up and squat! Ten.. Eleven…”

“Tell me you want to see my dick or I’m taking it out.”

“What?” Yang could see him reach down towards his pants. “No! Twelve! Stop! Thirteen!” 

“Say it! Say it or I’m taking it out!” 

“Say what?!” 

 He was getting her so confused and heated up that she could barely focus on counting. The moment she saw him unzip, she sprinted to stop him. “No, stop!...”

 Cardin sidestepped as she rushed him and let the momentum and the weight of her chest drive her into ground. Tits bouncing wildly, Yang slipped along the polished floor of the hall till she fell down and slid on her knees. I fell? 

 Behind her, Cardin went on squatting and counting confidently. “Twenty-two… Twenty-three… Well, that’s it then. Seems I won.”

“No, you didn’t! You tricked me. That’s not allowed.”

 Cardin put a finger in her face. “You lose again, Yang. Not my fault you can’t focus. You see how focused I am? Even despite that slutty little outfit of yours.”

 Hearing it described that way made her blush and readjust her sports bra. “You gave it to me, you doofus.”

“To put myself to the test. I’m just using you to strengthen my resilience, that’s all. Seems I’m doing great. Now, though, we do have to teach you a lesson.” 

 Cardin came over to her and grabbed her by the shoulder. “Come on, let’s start with some proper squats. 

 Yang tried to fight him off. “What do you mean?! We still have to play fairly. You distracted me.”

 He ignored her protests and grabbed a solid hold of her waist. Yang cursed under her breath but couldn’t get away from him, especially not in this outfit. He’s so annoying. 

 Cardin slowly lowered his hands until they were on her hips, his fingers stretching along her thighs dangerously close to her pussy. Yang could feel her back pushing up against his chest and the heat of his strong body made her flush. “Ready?” he asked.

 Yang gulped. “Let’s just get it over with, I guess.”

 Holding onto her, Cardin went down into a squat and brought her with him. Yang could feel him at her back, but the moment her glutes flexed to come down into the squat they pressed along his lower abdomen until they made their way over his crotch and grinded against the bumpy shaft of his cock. 

 Trembling, she raised herself back up, trying not to make too much of it. But it’s right there, I can feel it…

 The more she moved up and down pushing her ass against him, the harder his cock throbbed. Yang could feel it shift against her and wondered if he wasn’t feeling anything or just pretending not to. “That’s right,” Cardin told her casually as they worked out together, “don’t you stop.” 

 The dick was coming between her asscheeks and Yang could feel the heat burning up around her entire body. It’s right against me and it’s so big. What’s he trying to do? 

 As his hands came up to her waist and the fingers wrapped directly around her skin, Yang could feel tingles going from them all the way down to her lower pussy and striking. She trembled and gasped, knees getting weaker. Cardin was swaying from side to side and getting his powerful shaft to massage her ass.

“You’re terrible at working out,” he whispered. “Must be these big tits that are just tiring you out.”

“I don’t know if that’s it…” 

 Cardin lifted her chest playfully. “Aren’t they? But they’re so heavy.” The heated undersides of her breasts came to rest in his palms as his fingers skimmed along the sensitive skin there. 

 This brute is just trying to touch me, thought Yang. This should’ve been the time to push him off and tell him she was done, but he held her so tightly that it was difficult to do anything. Each time his hot breath hit the back of her neck she got goosebumps all over that brought out the butterflies in her tummy. 

“Damn, I knew they were huge, but they’re heavy too. What size are these?”

“They’re L cups,” admitted Yang shamefully.

“Wow. You like to act like you’re such a lady and a good sport, but you’ve got such slutty breasts.” 

 Cardin slipped a finger into her bra and Yang grabbed his hand to stop him. His open mouth traced along her cheek until he breathed right into her ear. “You best take your hand away, Yang. I’m just trying to help you. Plus, you did lose that bet. And that other little competition just now.” 

 Yang didn’t consider herself much of a loser of the latter and the former certainly did not entail any kind of groping of this kind. But somehow these strong hands on her body were feeling a lot better than she thought, and the cock she could feel against her ass was having an interesting effect on her body. Though she was slightly tired before, she felt completely energized now. 

 Cardin slipped his whole hand into her bra and groped the side of her breast hard. Yang yelped and tried to move away. He noticed how sensitive her breasts were and lifted the bra. “I think this might just be too tight for you.” 

 Yang made a handbra as soon as it came off; but Cardin moved her hands away by force and took control of her breasts instead. “They’re so nice and soft. Hot, too.” 

 The strong fingers pressed into the doughy flesh of her huge tits and bounced them up and down. Cardin whispered something to himself and kneaded them violently, pulling on them as if they were nothing more than playthings for his wants.

“Wait…” whispered Yang. “Ahh~” 

 He rolled her nipples between his fingers until she cooed and stretched them out. “Look at these lewd tits. How can you carry these around? No wonder you can’t do anything!”

“I can do everything~” Yang replied combatively, but her voice was just a lustful whisper. 

 Cardin pinched her nipples so hard that she tilted her head and cried out. “AAAaa!!~”

“You shouldn’t talk back after your performance. Beacon doesn’t need people with an attitude problem. At least this is letting me train my fingers. Strength training, you know?” 

 He groped her breasts in such a rough way that Yang knew that by the time he would be done with her they would hurt to the touch. He was just squeezing them, pulling on them, and slapping them around as if they were nothing more than funbags built for his strong hands.

 After a couple of minutes and playing around Yang felt weak and sensitive, but Cardin just laughed in her ear. 

“You know I’m giving you such good training. You should probably pay me back somehow.” 

 Suddenly, Cardin moved away from her. Yang cradled her own breasts and took a deep breath, hoping it was over, but when she turned around she could see that he was taking off his clothes. 

“What are you doing?...” 

 Cardin flexed the muscles of his thick arms and built torso, then let his shorts fall past his waist. Yang watched them drop inch by inch of their own momentul till they were left hanging at the base of his dick, offering a veiny and pulsating glimpse of what was underneath. She swallowed hard. The fabric slithered down, revealing one inch at a time until the whole cock bounced out. 

 His shaft was long and hard, throbbing in an appetizing way as it dangled between his legs. “Go on,” said Cardin. “I massaged your tits. I need some help too.”

“You’re not serious…”

“Look, we gotta help each other. We’re training partners.”

 Yang knew better than to fall for this sort of stuff. But admittedly that cock was so nice and juicy that it was difficult to look away. He had already awoken a sexual part of her while groping her before and now that part was taking over.

 With Cardin though? Seriously? She blamed herself for wanting this at all. This was the worst guy in all of Beacon. But that dick never did anything to anybody…

“Come on!” Cardin slapped his hands impatiently. “We’re just wasting time.” 

 Yang took a hesitant step towards him, then another and another until the wonderful cock was within reach. She put her hand under it and lifted it up until they made contact, then let the shaft slide over her palm as her fingers went towards his hanging balls. Though the cock was as stiff as steel and pumping with hot blood, the skin along the shaft was silky and pleasant to the touch. 

 Not bad. Yang licked her lips absentmindedly as she added another hand to it. Not bad at all. 

 Cardin put his hand on her head and sent her down to her knees. “Now it’s time for some other exercise.” He brought the tip up to her mouth and pressed it against her lips. “I’m going to need you to move back and forth. Just make sure you swallow it all the way down to the balls. That’s the way I can tell you’re doing it correctly.” 

 Your dirty pig. “Oh.” 

 Yang opened her mouth and gave the head a kiss, then pulled the foreskin and lapped at it till it was dripping with her drool. Cardin slowly inserted it into his mouth till the head pressed against her cheek, then forced her head down. 

 As the fat dick slid into her neck Yang could feel her heavy breasts hanging from her chest and heard the wet sloshing in her throat. She gagged and got tears in her eyes, but Cardin held her in place and insisted until the whole thing slid down. I’m taking it. I’m taking all of it!

 As her lips pressed against the base of his dick, Cardin said, “Wow,” and sounded genuinely impressed. “Most girls can’t do it that well from their first try.”

 Yang spit the glistening cock back out and gave it a kiss. “I told you, I know what I’m doing.” 

 It was no longer necessary for him to push her from this point because Yang was determined to have her fun no matter what. Maybe he thought he could just call her over here and take advantage of her, but that was his mistake. I have no problem taking advantage of this big cock instead, none at all…

 In fact, given his awful personality, she found it preferable that he just kept quiet and let her do the work. 

 Yang gripped the shaft powerfully with both hands and sucked the head forcefully, milking out several drops of precum. She savored their taste and swallowed it all down, then stroked the big dick with all her power as Cardin tilted his head and groaned like a big dumb animal.

“You like that?” teased Yang.

“Shut up…” he said, looking slightly embarrassed.

 Grinning, she ran her quick tongue along the head and flicked it ticklishly, then slid it under his foreskin to clean up his smegma. Yang could tell that it was having an effect on him so she decided to deepthroat the whole thing again - this time exercising her throat so she could squeeze the cock as hard as possible. 

 Cardin grabbed her by the ponytail and applied extra force, slamming his shaft down hard. His balls were slapping against her chin as he stretched out her throat like a condom, the noisy wet sounds echoing through the hall. Yang’s lips were stretched the whole way. Drool trickled out her nostrils. The tears streamed down her cheeks to drip onto her tits, which she now played with and abused, realizing just how much she enjoyed the rough treatment from before. 

 When the cock left her throat again, the whole thing remained connected to her mouth with thick ropes of spit. They made such a sloppy mess of it that they both smiled knowingly. 

 Cardin teased her lips with his dick and brought it down to her tits instead. “These tits need exercises most of all, look how fucking fat they are!” He slapped the shaft between them, but it was Yang that took over. She pressed them hard to squeeze his dick in and then slid them back and forth as he gazed down into her eyes. You like this, don’t you? You dumb guy... 

 A powerful shudder went through him from the applied pressure. The heat of his precum spreading along her tits made her lick her lips. “This is quite a workout…” 

“Clean up my dick,” he said, shoving the throbbing cock back into her mouth. “We’ve got more exercises to go through.” 

 Yang slurped up the drool from the cock and left it spotless. Cardin reached down and then stood up for him. She took her shorts off herself and as the gleaming little pink pussy came into view Cardin stared at it and went quiet. “Well?” asked Yang. “What are you waiting for?” 

 He grabbed her by the ponytail and took her over to one of the weight training benches. Her tits were so big that they spilled down the sides of her torso as he laid her on her back, though he quickly got on top of her. “This time, I just want you to push me up instead of any weights.” 

 Yang put her hands on his chest as if she were getting ready to lift. “Ready?” he asked. 

“Ready…” 

 As he lowered himself on top of her, Yang could feel the weight of his body pushing his dick deep inside her pussy. She spread her legs wider to make room for him, feeling his cock grinding its way up into her depths till her eyes rolled back in pleasure.

“That’s right,” said Cardin. “Now push.” 

 Fingers planted on his pecs, Yang pushed to lift him and felt the shaft halfway leaving her pussy. Her whole body trembled from the amazing feeling of domination it forced upon her. As he came down again, she gritted her teeth and lifted her right hip slightly to let him hit a sensitive spot. She gasped, cooing in response to his throbs, moving her hands in worship over his hard chest. 

“See, now you’re going to really break a sweat,” said Cardin. 

“Yeah,” said Yang. “I guess working out together really is for the best…” 

 His hands grabbed her tits against and lifted them back up on her chest, playing with them as she fucked herself with his cock and pushed him in and out. He was heavy enough that her arms were actually straining to lift up his body, though each time the cock penetrated her tight little pussy made her back arch in pleasure. 

 They did it like that for a couple of minutes till her arms ached and fell to the side. Cardin grinned and pinched her nipples hard, thrusting a couple of times into her by himself. “Not bad, Yang, not bad.” 

 He took her off the bench and led her over to one of the pull-up bars. “Here. I want you to grab this and pull yourself all the way up.” 

 Yang was so horny that she could barely stand straight. She smirked and put her hands on his cock. “Why don’t we just finish up somewhere comfortable first?” 

 Cardin turned her around and put his hands on her waist again. “Come on, don’t be a quitter. Hop up and grab the bar.” 

 Yang did as instructed, though she was having trouble lifting herself up the entire way. Her arms weren’t that strong to begin with, and lately her tits had grown so much that it was difficult to do most exercises with them, especially now when she could feel their weight shifting along her torso. 

 A moment later she dropped down and dusted her hands. “I can’t,” said Yang, sounding tired. “I just can’t.” 

“Where’s your stamina?!” he demanded. “Fine, fine, I’ll help you.” 

“I’m not sure that will work…” 

 Yang wasn’t sure what he was going to do. But then she could feel the head of his cock rubbing against her pussy from behind. She smiled and tightened her thighs around it, eager to get fucked for real. There’s no reason for pretense. He should just do it if that’s what he wants.

 Cardin slapped her bubble butt hard and parted it. Yang jumped as the cock moved up from her pussy to her asshole; but she remained still. The mere thought of that big dick entering her tight butt gave rise to panic, though, at the same time, she didn’t want to look weak in front of Cardin. 

 He wrapped his strong arms around her whole body and rammed it into the virgin hole with an experienced thrust that left her speechless. Yang’s mouth opened wide as the throbbing shaft slid into her tight ass, her fists balling up with tension. 

 Cardin lifted her body up to drive his cock in even deeper and then let her come down fully impaled on it. Shaking wildly, Yang could feel the dick in her ass from every movement. “Come on,” he said. “I’ll lift you up.” 

 As Cardin brought her arms up to the bar, Yang could feel more than half his cock leave her ass. She sighed deeply, though her arms weren’t any stronger in the meantime. She was about to fall again and come on it when Cardin gripped the bar too. 

 As he lifted himself and came up, Yang could feel the whole cock going back into her ass and lifting her up as well. She worked along with the exercise and rose all the way to the bar. “See,” said Cardin. “You’re doing it.” 

 They dropped back down and a shiver went through her, though Cardin slapped her ass to go again immediately. Yang gasped as the cock impaled her ass and lifted her up into the air, her hands desperately trying to exert enough power on the bar. 

“Fuck,” she whispered.  

 Each time she came down her tits were slapping against her body, though Cardin clearly liked how much it was getting out of her. He stopped giving her a chance to relax in between thrusts and picked up the pace, relentlessly lifting her up and down as his dick broke her ass.

 It was going so deep that Yang could no longer take it after fifteen repetitions. She could feel her whole body winding up for an orgasm and her mind unraveling from the pleasure. He’s just stretching me out however he wants…

 Cardin sensed her readiness and slapped her bubble butt red. “You’re done already? That’s so disappointing.” 

 The next time he brought her down he turned her around and slapped her face. It was so disorienting that Yang paid no attention to the fact that his dick left her ass and quickly entered her pussy instead, lifting her up against the wall.

 His mouth found her tits and bit on them like a wild animal, sucking her breasts into his mouth in the frenzy of the moment. He’s marking them as his, thought Yang with a sick sense of pride. She allowed him to have his way with her body as he fucked her, stretching her nipples with his teeth, biting them until she teared up, and licking her big pale tits like the finest of desserts. He loved them. She could tell.

 His hands were gripping her ass the whole time, kneading the glutes mercilessly as his dick and mouth did most of the work. Every so often he would land a spank across the sensitive cheeks that made her shudder and gasp, realizing her poor butt would be red and marked by him for weeks, if not months to come. 

 He’s treating me like I’m his property!~ It should’ve made her mad, but it only got Young feverishly horny for him and made her put all her focus into holding his dick in and squeezing every drop out of his huge balls. Despite the brutal fucking he dished out, she could feel the shivers going through him from the way she massaged him inside of her.

 Cardin slammed into her with a powerful thrust and unleashed his load at the same time, sending his seed all up into her womb. Yang realized what she was doing but far too late, and the insignificant struggle she put up was meaningless in the face of so much force. He’s so strong~

 In the end, she just caressed his shoulders and cheekbones as the hot cum entered her body to impregnate her. “Oh my~”

 Cardin pulled out of her with a grin. “Well, that’s done. Hope you enjoyed your workout.” 

 He left her there dripping with seed and headed towards the showers. But if he thought that would be it, then he was kidding himself. You started this!

 Yang went after him and entered by force as he washed. “This is for guys only,” he protested. 

 She kissed him deeply and stroked his cock. “Well, I might have a little boy inside of me now.”

 Cardin blushed and lifted her tits. “Or a slutty girl like you, huh?” 

 Yang slapped him. “Don’t talk that way.” 

 He laughed and squirted some soap over her chest. “I’m guessing you want to workout more from now on?” 

 Yang lowered her hand down to his juicy balls and felt just how heavy they were. There was probably way more seed inside. All mine~ “Oh, without a doubt. I need lots and lots of training.” 
 As the shower ran loudly, they pressed against each other and kissed, their slippery and wet bodies rubbing against one another...
