Colin was hardly concerned about the fact that either of them would be very exposed. Being naked was perfectly natural. He smiled into the kiss as he returned it. He very much liked all these kisses. However, the lack of contact as Justin sat up? That, he very much did not like. There was no rational reason not to like it. His mind was just clinging onto how very much he liked the way that it felt. He lifted his hips to make it easier for him to get his pajama pants off. He didn't need them.
Colin leaned up into the kiss, humming softly. Kisses made the lack of skin contact better. When Justin took off his pants, Colin couldn't help but stare. He was so pretty, so lovely. He made a small noise, hands immediately moving to touch his skin as he moved over him. "So lovely," he murmured, arching up toward Justin's hips.
He moaned softly, letting his hands explore the newly exposed skin. He liked this. He wanted this. "Mmm...Should sleep naked more," he said as his fingers ran up Justin's back, dragging back down lightly with his nails. Clothes were quite unnecessary when sleeping anyway. He just wanted to always feel Justin's skin. No need to mute the feeling with clothing.
