Jaune stood in the center of JNPR's dorm room, naked as the day he was born. His hands rested behind his back, stretched across his body to draw his shoulders out and without his clothes, every muscle, from his abs, to his traps to his deltoids rose from under the surface of his skin, not bulging grotesquely, like some men he had seen, where everything got too big to even look comfortable but thick and hard enough to give a hint of what it would be like to touch them. To run his fingers across them and squeeze them. To be held by them.
Staring at him it was hard to remember what he had been like when he had first arrived at Beacon. Tall and cute but lanky. Born with a frame that he had squandered and never bothered to grow into. The only thing of worth on him being his dick, thick then and thicker  and longer now with the baby fat of his pelvis gone. Of all the pieces on him that stood out, it was the most promient, springing out ahead of him, begging to be touched.
"Uh Ren? I can do this all day, but you know."
He said it with a smile and a blush, steady breaths from the slight extersion of flexing. It was soft, welcoming, but it snapped Ren from his reverie, back to reality of what lay in the room in front of him.
"Sorry."
It had begun as an idea from Jaune, after a marathon session where the blond had guiltily noted tht more often than not it was Ren who would be on the top or bottom, ass spread to recieve Jaune's cock. It had lead to and awkward conversation about the nature of their relationship. About who was the man and who was the woman and another idiotic thing until the blond had suggested the play, as a way to make up for the selfishness that existed only in Jaune's head. A session when the girls were out of the room for a night, where Jaune would do anything, submit to anything Ren wanted.
Saying yes held some implications that the constant fuckings were negative in some ways, but the idea of Jaune, submissive and presenting seemed so tempting that he hadn't hesistated much before agreeing.
As soon as the girls had left, and a safe five minutes were given to make sure they were gone, Ren had been asked to leave the room with his scroll, to await a text that would come when everything was ready. When he had recieved it, he had returned to this sight Jaune's naked body and his loving smile.
That smile had been the problem. If it had been lustful, or annoyed maybe he wouldn't have hesitated as he did but it was so Jaune that he had stopped to take it in. A goofy grin like he had figured something out, tinged with happieness that the was doing something nice for someone he loved.
It vaguely occured to him, as Jaune's smile began to become a confused one, that he had been standing there, even after apologizing and he reached out to touch the most appealing part of him.
He ran the knuckles of his fingers across Jaune's cheek, opening them to grasp his head and brush his loose hair once then twice. Jaune smiled at him, and it took every ounce of self control Ren had not to kiss him there, to fall into one of their fucks on his bed. It was his night  though, his night to touch and squeeze and instead he lowered himself to knees.
Jaune's cock was there, begging to be touched but he had agreed to give every part of him that night so Ren began with his calves. Reaching around, beginning where the fat and wide muscle began, he started to knead it. Exploring it's edges, feeling its firmness, trying to push it down and coming away with sore fingers. He moved up to his thighs, sliding his hands up and his hands were forced open as Jaune's leg grew thicker. His cock was tantalizing close, but he ignored it as best as he could, rubbing his hand along the diameter of the things and pausing to feel the muscles between Jaune thighs.
This is where some of that power came from. The power that bruised his ass cheeks and pinned him to the bed, making him scream like a woman. Not all of it but a part. The main work horse lay above.
Ren squeezed that muscle one last time, and began to travel up. He let his hands gently glide along the skin of Jaune's balls, elicting a low, wanting moan from him, and finally reached the prize as he encircled his body.
An ass tight enough to bounce a coin off of. It had been a saying he had heard before, never quite understanding what it meant, but there and then, feeling it, the saying took a sudden clarity. It was muscle and power. The little cushioning on it, drawn across something strong and unbearably firm. His hands weren't quite large enough to completely encircle each cheek but it was just enough that he could draw them apart and feel them close together again.
An urge popped into his mind. One he never had the chance to act on, but now seemed not only possible but a crime not to do. With another squeeze, he drew his hand back and gave it a smack.
Ren felt something dribble on his chest and realized that as he had moved close to touch, Jaune's cock had been forced down his chest. The dribble was liquid, leaking from it's head and reaching down to wipe it with his thumb he realized it was pre cum.
Ren felt a wave of lust run through the entirity of his body, from his head to his toes. The urge to lunge forward, to take his entire girth in his mouth and draw out the rest, almost overwhelmed but he fought it off, somehow, reminding himself that only half of Jaune's body had been explored.
Looking up, head level with Jaune's abs, Ren found the strength to move his hands away from Jaune's ass to rest them at his hips. Rubbing circles in the meat, he inched his way along the expanse of Jaune's lower belly, rolling what fat or skin was left until he reached the first of his abs.
When he had first seen them, some months into Jaune's training, Ren had been overcome by an urge to lick them. In the months since he had touched them, drank off them (chocolate milk, for some reason that only made sense to Jaune) and rubbed his cock along them. Still, they were as fascinating as they had been the first time he had seen them. Little protrusions, that would flex when Jaune would breathe deeply. The thought occurred to him that he could stay there for hours, just running his hands along them but that wouldn't be productive to the game.
He tore his eyes away and, nearly standing found himself eye to eye with one of Jaune's nipples. They weren't nearly as interesting as the muscles they were attached to, but he had seen how hard they would get in the throes of sex. With a little grin, he adjusted Jaune's cock, to make the tip rest directly in front of his legs and with a small lean bit down on the nipple.
Jaune's moan began from low in his throat and erupted from his mouth. Ren felt liquid splash against his thighs and stood to his full height, moving his hands from Jaune's sides to encircle his chest. He was shorter than Jaune by a good, seven inches but all it meant was that when they embraced, his face fit perfectly into his neck. He could smell his sweat and shampoo, the way they mixed together to make the smell that helped with the nightmares and let him dissapear into his chest.
"Jaune."
"Y-yeah?"
"Close your thighs. Please?"
Ren felt him shuffle and pressed his hip forward, his dick, painfully hard pressing against the muscle of Jaune's legs. He had been leaking cum since had entered the room and stripped. He hadn't cum, like Jaune, but it was enough to wipe along his skin in a parody of lubrication.
"Ren?"
"Just hold still."
He pressed his hip forward, trying to force his way through the small gap. He moved slowly, Jaune not fighting it, but understanding what Ren wanted, and when he finally began to pump his hips, the pleasure came in waves. It was tight. Tighter than Jaune's mouth, his hands, tight enough that he could feel the meat of his dick defined between the slabs of muscle. He heard moans and realized it was himself, huffing in Jaune's smell and trying not to come too quickly, before getting to enjoy it as much as possible.
His orgasism suprised him. It came suddenly and like a thunderbolt, his knees buckling and his ankles rolling. Jaune caught him before he could fall but for several seconds, his body hung limp from Jaune's arms, bonelessly.
He felt Jaune's hands began to thread through his hair
It, Ren thought once some ability to think returned, was not a bad trade for getting fucked in the ass by the one you loved.
