Theo kissed back almost like he hadn't been expecting it, like he'd never really woken up from his sleepwalking, but he settled in against it soon and even this was sleepy, slow, relaxed.
That is, until Greg slid a hand around his hip, down to squeeze his ass and the kiss turned a little less sleepy, a little more heated, needy. When Greg pulled away to compliment, Theo was left flushed in the face and still dewey-eyed from sleep, his mouth all kiss-bruised and his hair a riot. "Oh..." Theo had time to murmur before his thoughts were pushed out of the way by yet another kiss.
