Flexin' in the Moonlight

After a night with a total beefcake of a woman, Yang turns into a were-bodybuilder

Work Text:

About a month ago, Yang had a passionate night with an absolute beefcake of a woman. Of course, they didn’t go all the way, not even Yang could bully Junior into allowing that at his club, but the pair spent more time kissing each other than doing anything else that night. Ever since then, that woman, her strong, handsome face, and those incredible, superhuman muscles just wouldn’t leave her mind. Yang wasn’t entirely sure if she wanted another round with that woman, wanted to be as buff as her, or both. At the very least, she spent a considerable amount of time in the gym over the last month, achieving respectable gains considering the short time frame. She wasn’t a mass monster like that hulking beauty she slept with, but she was happy with the extra toning her muscles gained over that month.

 

As Yang strode towards Junior’s, hoping to meet that woman there again, the solid blanket of star-covering clouds broke, and the full moon shone through. Seemingly out of nowhere, Yang felt lightheaded and dizzy. Not wanting to cause a scene, Yang ducked into a nearby alleyway. Sure, it wasn’t the safest choice, but it was better than being out in the open. Yang planted her hands against a poster advertising a bodybuilding contest on the wall and let her head hang between them, taking in slow, deep breaths to steady herself. While trying to do so, she heard a sudden metallic ping that seemed to snap her out of her daze. As she looked up and tried to find the source, there was another ping. Being more alert now, Yang immediately found the source, although she did not entirely believe it.

 

Her sleeves’ cuffs had popped open, and her biceps bulged like she had been flexing hard. Yang wasn’t putting in any effort for this, so that mass was, apparently, all natural. Before Yang could be properly worried, a wave of pleasure hit her whole body, causing her to buckle and fall to a knee, looking up at the moon as she began to grow all over. From her biceps, abs, and glutes making her clothes tight, to thicker hands tightening her fingerless gloves and her swelling calves starting to undo her boots, every muscle on her body grew, with Yang panting and grunting from the strain. Yet, the difficulty felt more like a good workout than anything else, so Yang welcomed it, and it made itself welcome.

 

Between her thighs thickening to the size of tree trunks and glutes expanding to the size of volleyballs, her spandex shorts rode up and up, looking more like bloomers than shorts. Most other shorts would have given out under such strain, but fortunately, Yang’s shorts were tough and stretchy enough to handle her sudden growth.

 

The same could not be said for her jacket. At first, it was pinching in her widening shoulders and tightly hugging her broadening chest. Before long, her widening lats and surging pecs forced her jacket to pop open. While that briefly relieved some pressure on the jacket, it didn’t last. Soon, her growing delts and biceps were destroying her formerly puffy sleeves while threatening to pull her jacket in half. In a fit of lunacy, Yang let out a bestial growl and brought her arms flexing inwards, putting more and more pressure on the back of her jacket until it tore, almost entirely hands-free. Yang reached back to finish off the collar, while her delts finished destroying the sleeves, causing the remaining tatters of her jacket to fall, forgotten, to the ground. They were soon joined by the snapped remains of Ember Celica, their matching bracelet form unable to handle the increased mass beneath them.

 

This revealed the incredibly tight tube top Yang wore. Her emblem on her breast was stretched and warped, while the top was turned into more of a breast band due to its struggle to hang on around Yang’s superhumanly broad chest.

 

Her scarf also loosened itself as Yang’s neck grew thicker and more powerful, and her traps rose to push it out of the way, matching the solid, strong jawline that had begun to form, giving her a hunky face to match her new figure.

 

As Yang finished growing, she slowly, cautiously, rose to her feet. Yang wasn’t sure if what remained of her clothes was loudly begging for mercy or if her hearing had been enhanced, but every movement, even as little as breathing, brought about creaking like everything she wore was being pushed to its limits. She tried to examine her body, but much of it was blocked by her bulky chest muscles. So, instead, she decided to get a feel for it. Yang slowly ran her hands up her thick, corded thighs and her abs and obliques, letting her fingers drop into every divinely chiselled crevasse between meaty muscles as she flexed everything she could, giving her a better idea of her newly gained power. Considering how much of her field of view was blocked by her expanded chest, she hardly needed a feel for it. So, instead, she flexed her mighty pectorals to make them bounce for her viewing pleasure, savouring the sound of her top creaking as it struggled to contain her. She then brought each arm out one by one and flexed upwards, making her biceps swell to the size of her head, an impressive feat even if some might misjudge her head’s size due to her thick neck and high-rising traps.


“Either this is the best dream ever, or I’m the luckiest woman alive,” Yang said to herself through a manic, toothy grin as she admired her mighty arms with wild red eyes. ‘I’ll be even luckier if that buff babe from last time is at Junior’s. A workout with her, pushing each other to our limits, would feel divine,’ she thought, managing to make her monologue internal again. ‘If she’s not, I can always find another hot chick to watch me work out all night long, getting bigger, getting stronger,’ she added as she stuffed her undone laces into her boots and marched out of the alleyway towards Junior’s. She barely even cared about how awkward all of that muscle made her stride, nor how many passersby were staring at the muscle beast that Yang had become. If anything, she invited the stares, as long as they enjoyed the view as much as she enjoyed this incredible body.

Merry Christmas, enjoy your smut, everyone!

I hope y'all enjoyed this, because I really enjoyed writing it. Guess I was just really in the mood to write about a were-bodybuilder or whatever we're calling it.

That's all I can think of for this author's note, so yeah.
