Despite his protestations, Gus knows at least a passable amount about how to wrestle, and he gets Geoff in a sloppy half-guard, laying his chest across Geoff’s. He intends to stop the situation right then, but instead Geoff is hipping up and shimmying out from under him and half-losing his ancient pajama pants in the process. Whatever anger Gus had been feeling drains out of him as he slaps Geoff’s bare ass hard, enjoying the shocked expression on Geoff’s face that dissolves quickly into laughter at the incredibly loud “SMACK” it makes. 

Gus ends up laughing too hard to fight back as Geoff pulls his own pants back up and rolls Gus onto his back, getting him in a full mount position, knees on either side of Gus’ hips and his full weight leveraged across Gus’ belly.

“You gonna ground and pound me, fuckin Chuck Liddell?” Gus says, laughing.

“You make it sound so sexy when you put it like that,” Geoff says, smiling and leaning hard onto Gus. Geoff hooks his feet and ankles around Gus’ calves in an uncomfortable little piece of jiu jitsu that has them pressed together from knee to nipple.

Gus hips up once, twice, three times, picking Geoff’s entire weight almost completely up off the carpet -- and exhausting himself in the process. 

“Powerful thrusts from a man who says he can’t fight,” Geoff says, hitching an eyebrow but not letting up, leaning to push more of his weight across Gus until he’s right in his friend’s face, the length of their entire bodies pressed together. 

“I give up, I’m tired,” Gus says, letting his head flop back dramatically. “Have your way with me.” 

“Finally,” Geoff says, and he’s right there, so close Gus can smell the booze on his breath, and he’s staring at Gus with this amused, half-adoring look like Gus has just told the best joke -- and he shifts just so and -- 

“Are you fuckin’ hard right now?” Gus says, the words out of his mouth before he can even think through the fact that it’s true, that he can feel the clear pressure of Geoff’s hardening cock across his own groin -- and he’s laughing harder now, almost choking for air because Geoff had really brought this one on himself, he’d fucking asked for it and now Gus would have something to tease him about for the rest of his goddamned life. 

“What?” Geoff says, sounding shocked. He shifts his weight. “I -- uhh. Maybe?” 

“I’m so in tune with your cock, I know before you do when you have a hard-on,” Gus says. “I think we’ve been living together too long.” 

And Gus is only joking -- had really only thought it was one of those weird accidental, don’t-know-why-this-happened-when-nothing-sexy-is-going-on boners -- but suddenly Geoff is shifting back, unhooking his feet, easing off of him, rolling off and to the side, and getting up. It’s abrupt and quiet and so quick it seems a little panicked -- and Gus isn’t laughing anymore because Geoff won’t meet his eyes.

“Hey man, I’m just fucking with you,” Gus says, sitting up and rubbing the back of his head. “You cool?” 

“Yeah -- I -- it’s really late,” Geoff says, already walking towards his room. “I’m gonna call it a night, dude.”
