Colin moaned a little, hips arching towards Zach's. He was still not understanding all of this. The only thing he understood was that the added pressure of Justin's weight on top of him had made everything press closer. He didn't know if other people liked doing that, though. It could just be Justin.
He nodded at Zach's words. It still didn't make complete sense, but he would take it for what it was. Squirming around a little, Colin managed to slip out of his shirt. It was only in the way and rubbing uncomfortably anyway. He wasn't sure if Zach was one of those people that was made uncomfortable by people not being clothed properly. Only he was the one that had pulled it up so far. He shivered slightly before pressing close again.
He still couldn't explain this strange need for being close and the touching. His hand slipped under Zach's shirt, wondering if he liked nails on his back too. He pressed a quick kiss to his chin before moving to lightly drag his nails over Zach's skin. Colin liked the way that felt so he hoped it was okay for Zach too. If Zach didn't like it, then he wouldn't do it again. That was simple enough...right?
