It always ended up like this, with Wei Wuxian and Jiang Cheng groaning desperately into each other's mouths as they humped and grinded and squirmed against each other, rolling around on the floor to try to get the upper hand on each other and be the one to make the other one cum while simultaneously chasing after their own pleasure.
They fought and bantered and bickered and wrestled like this often enough that everyone had long accepted that this was how they showed each other their love for one another, and had simply chuckled and brushed their constant rivalry aside as a part of their brotherhood. All of this was true, of course, but the rivalry hadn't dissipated now that they were adults and had a shared college dorm room to themselves. If anything, their competitive nature and rivalry had increased.
The only thing that was different now was that they were no longer denying the attraction between them that had been there from the very beginning, and were now acting on it instead. They'd hidden it well beneath their usual bickering and competitive “brotherly” rivalry, of course. But when alone like this, with most of the building empty due to the approaching holidays, they were free to roll around and wrestle with a bit more abandon than usual.
Wei Wuxian rolled on top of Jiang Cheng, spread his knees on either side of his brother, then thrust his jeans-clad hips as hard and smoothly as he could into Jiang Cheng's shorts-covered crotch and pressed his mouth against his brother's to muffle his moan. Wei Wuxian was the best at this, and was determined to prove to Jiang Cheng once and for all that he was the one who could make his brother cum quicker than anyone else could just by humping him. That meant he needed to make Jiang Cheng cum in his shorts, and he was going to win at all costs.
It wouldn't count as cheating to the competition if he braced his elbows on either side of Jiang Cheng's head and slid a hand into his brother's hair to pull it, so that's exactly what he did. Jiang Cheng arched up against him, clutching at his t-shirt as he tried to grind back up against Wei Wuxian's powerful thrusts with a whine building in his throat.
Wei Wuxian held him down and kept his pace steady, knowing that building the rhythm up like this would make Jiang Cheng cum quicker, even as he kissed his gasps and whines off his lips. Jiang Cheng reached around him and grabbed at the back of his t-shirt desperately, and Wei Wuxian used his grip on his brother's hair to pull his head back even more so he could nip and lick at his sensitive neck, moving up to his lips to kiss away his moans every so often.
Jiang Cheng was usually not one to give up, but he couldn't deny that Wei Wuxian was good at this. His brother has spent the entire time here alternating between slutting around with pretty men and women and showing everyone up at class, students and lecturers alike. He was a genius not for nothing, after all, like his mother had been before his parents had passed away and Jiang Cheng's parents had adopted him. Wei Wuxian was always so good and diligent at learning and perfecting anything that he felt was an important skill to learn.
Apparently, Wei Wuxian had felt that learning how to hump your brother until he came in his pants was important enough that he had to become an expert at it, and Jiang Cheng was already trembling beneath the adrenaline and rush of hormones of one of the usual fights turning into something more, let alone when such a heady rush was combined with his brother's hot mouth expertly sucking at all of his spots on his already sensitive neck.
“Hnng, fuck, A-Xian!” Jiang Cheng gasped, giving up the competition for once and clutching at the back of his brother's neck and shoulders as they squirmed together until they ended up with a leg between their respective thighs.
“Hump my leg, A-Cheng. I want to make you cum in your pants for me,” Wei Wuxian murmured in his ear, and Jiang Cheng whined and thrusted his hips sharply into Wei Wuxian's thigh.
“Good boy,” Wei Wuxian almost purred, and Jiang Cheng groaned and flipped them over, before grabbing a fistful of Wei Wuxian's longer hair and pinning his beautiful brother to the floor.
“Fuck you, you're supposed to be my good boy, not the other way around,” he growled, deciding that if Wei Wuxian was going to be a little shit and stir up his praise kink and combine it with his favourite pet name like this, then he was going to make the fucker cum before him in retaliation, and then he'd fuck his face and accept the sight of Wei Wuxian's face covered in his cum as his apology from his brother for being such a teasing little shit to him.
They rolled around and wrestled as the only people still left to leave the building, as they'd avoided the travel rush by waiting an extra week before booking their train home. They'd wrestled pretty much every single day, and, well. They did more than that, too. It just always started with the wrestling though, without fail.
And it always ended, too, with one of them coming helplessly in his pants with a desperate shout that was drowned out in the mouth of the other. They writhed and squirmed and rolled around on the floor, wrestling for control; for pleasure; for the sheer, pure joy of wrestling with one's brother; and for the even greater joy of being the one to make said brother gasp out one’s name like a prayer as he helplessly humped his brother's thigh and chased his pleasure.
Wei Wuxian had cum first and clung to Jiang Cheng, who kissed and kissed and humped him back until he was teary eyed and sweaty from overstimulation, and looking up at his brother as if he'd hung the stars with those gorgeous dark eyes of his. Jiang Cheng could not resist it and grabbed another fistful of Wei Wuxian's hair and kissed him until Wei Wuxian was whispering his name.
“What is it, baby boy? Have you finally learned your place now?” He asked, smirking and taunting his wrecked brother.
“Nah. Just wanted to say your name,” Wei Wuxian gasped out, trying not to sound too affected, and Jiang Cheng snorted as his brother failed to fool anyone into thinking that he wasn't mindblown by the force of the orgasm Jiang Cheng had just given him.
And then Wei Wuxian abruptly flipped him and Jiang Cheng's back hit the floor hard. Wei Wuxian was hovering over him with a devious, cocky and mischievous smirk on his face, and fuck, his brother was even hotter like this.
Before Jiang Cheng could even think past the thundering of his pulse and the twitch in his dick, Wei Wuxian had untied his shorts and yanked them down enough to expose his dick to the cool dorm air.
“You might've won the battle, but you didn't win the war, A-Cheng~” Wei Wuxian singsonged, and then swallowed down the entirety of Jiang Cheng's dick in one go.
Jiang Cheng had to bite down on his fist to hide his moan as he exploded into pleasure after that first, gloriously hard suck that Wei Wuxian had given him.
When he crashed dizzyingly back down into his body, Wei Wuxian was still slurping up his dick and licking him clean of any cum, and then pressed a kiss to his rapidly softening dick. Wei Wuxian kissed up Jiang Cheng's body and settled gently on top of him, propping himself up on his elbows and shoving his hands into Jiang Cheng's deliciously messy hair, massaging deeply into his scalp and kissing him just as deeply.
“That's my good boy, A-Cheng,” Wei Wuxian praised with a soft smirk, and Jiang Cheng made a mental note in his fuzzy brain that he was going to have the upper hand next time, and he was going to make Wei Wuxian be the one dazed with pleasure the next time they wrestled. He was such a little shit, and Jiang Cheng wouldn't change his mind on that, even if Wei Wuxian laughed so prettily into his mouth when Jiang Cheng bit his lip in retaliation. Someday, he was going to win, Jiang Cheng promised himself, and bit his brother's lip again, for luck.
