As Zach moved back, Colin moved onto the bed on his knees, straddling Zach's lap. His hands pushed Zach back toward the bed, following so as not to break the kiss. He knew he would need a break for breath soon, but he didn't feel like doing so at the moment.
His hands moved after a moment to explore Zach's skin once again, going over paths he'd learned and trying out new combinations. If he was any good with an instrument, he might say it was like playing one, but it was more like taking pictures. You just had to see what worked and what didn't. Letting his nails lightly graze over the skin, he briefly pulled back, if only to catch his breath. His eyes opened, looking down at Zach curiously for a moment. He was very pretty like this and he wanted nothing more than a few pictures to remind him.
