Theo nuzzled in as Greg rocked him back, satisfying a need in him that was base and more instinctive than obeying a commanding tone. "I know you, don't I?" he said softly, looking back at Greg briefly before he was kissed. He almost struggled at first but he was calm, relaxed, kissing Greg back in a way that he remembered from before but there was a different kind of submission there now.
There was a submission there that came because there wasn't anything more of Theo anymore that could be anything but submissive; he wasn't well enough, yet anyway, to make decisions, to be independent, to be the person he once was.
He held back to Greg and let himself be drowned in the kiss, falling into it and forgetting that he hadn't been there for days and years. He thought he had homework to do.
