Every whimper, every moan, only served to make Rez pulse inside his jeans. He couldn't take it anymore. He wanted him so bad. Fuck, he needed him. And as Riley returned the sentiment, Rez found himself moaning softly, eager hands quick to shove the older man's jeans and boxers down, sitting back on his knees so that Riley could help him with his own, kicking them off, the both of them left naked.
Grasping Riley's cock in one hand, Rez slid his own against it, precum seeping from the head lightly slicking both their shafts as he rolled his hips, stroking them both simultaneously, the more sensitive parts of their shafts pressed together. It made him tremble, panting softly above him as his other hand teased Riley's nipples, pinching and pulling upon them, before moving up to his mouth so he could suck on his fingers, getting them nice and wet.
He didn't have any lube, and while Riley may have possibly brought some with him, Rez was more than ready and willing to improvise. Once his fingers were nice and adequately slicked, he moved them down to press against the other man's tight hole, slowly pushing into him as he continued to roll his hips, continued to slide their hard cocks together, making them both pulse.
Fucking him with his fingers, still on his knees, straddling the other man, Rez peered down at Riley with lust-filled eyes. "How bad do you want me?" His voice was low and raspy, the desire just as evident in that as it was in the hard cock held in his hand. "Tell me," he whispered. "And I'll give you what you want."
