He trembles a little at the touch but doesn't seem to freak out this time, instead just wrapping all of his limbs around Steve more tightly. He tilts his head a little and parts his lips further, allowing the other man in. He tries to meet that tongue with his own -- still a bit clumsy, and about the opposite of assertive, but he doesn't want Steve to think he's not participating.

Which... he's not even sure what the truth is. He tries to focus all of his attention on the kiss, take note of what the other man is doing and how. He could maybe learn from this. But at the same time, he can't help but feel detached. He wonders if this memory too is going to delete itself from his head as soon as there's some distance between them.
