It wasn't a dream, but he was caught between waking and sleeping, that thin twilight place where he was aware, but not fully awake. His mate was moving, but not leaving the bed, the mattress hadn't bounced with the absence of his weight, and he made a groggy, questioning noise without his eyes ever opening.
Maybe he should have woken up a little more. Then he could have watched his mate toying with his length, kissing and licking his way up, before he finally took it in--
Derek moaned, his entire body arching as he slammed into wakefulness. both hands coming down to cup the back of Stiles' head. It was all hot, wet suction that had his thighs tensing beneath Stiles' weight. "Fuck, baby. Good morning to you too," he growled out, eyes finally flickering open to look down, another moan ripping free as he watched his cock disappear between those plush, pink lips.
This was so much better than any dream he could have been having. "God, Stiles, your mouth --" One hand traced the line of his cheek down, thumb swiping over the shiny corner. "It feels so fucking good," he moaned, hips slowly leaving the bed to thrust up, careful not to surprise him and make him choke.
