There is no fear in Adam right now, at least not as far as Ronan is concerned. He has fear, of course, but with Ronan, right now, in this moment, his mind is shut off from over-thinking everything. There's only the fact that he likes Ronan, that he likes that Ronan likes him, that he wants certain things from Ronan and only from Ronan. He wants and is wanted.

Adam lifts his arms, shirt easily coming off and tossed aside along with Ronan's, which leaves them both in those jumpsuits open and hanging at their hips. Adam is kissing Ronan again because he wants to, because he can, because Ronan isn't stopping him. Ronan isn't even stopping his hands as they slide over Ronan's body.
