Colin made a small noise as he bit down on his lip. Oh. Fingers. How had Zach known to do that? Why did it feel that way? Why his nipple? He didn't know, all he knew was that it felt good. It felt amazing. He rearranged his legs so they were closer. He arched toward him, groaning softly. Whatever this was, it felt good.
Zach's reaction to his fingernails made Colin blink a few times. He really liked that, it seemed. His name sounded nice like that, he decided before repeating the action as many times as he could. He wanted to hear those noises again. Another curious response. He paused for a moment before pushing at Zach's shirt. He wanted to feel more of Zach's skin. Did it feel as nice with other people?
He moved down along his body, pressing a quick kiss to the closest bit of exposed skin. He liked this. He wondered how much he was allowed to do here. He should ask before touching, shouldn't he? "Am I allowed," he asked curiously after a moment.
