Though he didn't sleep. He lay and listened to Taff's breathing. He lay and listened to it slowing down until his little brother was asleep. And then he let himself relax. He let himself fall asleep.
Tristan awoke early. Maybe because of the heat of his own body and the desperate horniness he felt from being so close to Taff. He was silent, listening, realising Taff was still asleep. His arm slid around his brother, splaying his hand on his chest. His bare chest. The hard, firm muscles. The heat rising up from between his brother's legs.
Tristan couldn't help himself. His fingers traced the outline of Taff's cock.
