Sirius let out a shuddering gasp as Remus staked his claim, nodding his head mutely as he struggled to pull the other boy's shirt off as well. He wanted the same things as Remus, needed them in fact. They couldn't stop now, else Sirius might lose his mind. He was so wrapped up in the noises Remus was making, the things he was doing, the way his hands were moving. It all worked together to bring him to the edge of orgasm but not quite. Of course, it was a new experience entirely to be this close without having done anything other than kiss and touch.
"Rem" he gasped, tugging him closer, his voice pleading as he writhed beneath the other boy. "Rem" he groaned out again, arching up into him and connecting their lips in a hungry kiss.
