[Rean isn't sure what about this is pure at all, actually? But he doesn't ask, listening and feeling his cheeks heat and his pants get uncomfortably tight until he has to press his face to the door and try to cool his skin down with the smooth wood.

He wants to go right in there and leave marks on Crow right now. But he isn't sure if the timing is right, he isn't sure what the right timing IS, actually, which is why they haven't done anything but make out and cuddle so far. He doesn't want to rush.

Reminding himself he doesn't want to rush is the only thing that keeps him from asking Crow if he can come in, and after a deep breath, he manages in a fairly steady voice:]

Okay. That sounds... Really nice. I'd like to do that, when we're ready. Thank you. Um. Is there anything else?

[While he's thinking of things to mentally prepare for and study, he might as well make a proper list. And honestly there's just something nice about how erotic it is to know Crow is naked and wet on the other side of this door, and yet opening up to Rean about his sexual fantasies. It's the opening up that's more exciting than anything, more appealing than the thought of any physical act(and yeah those thoughts ARE super nice), the knowledge of Crow being honest and vulnerable with him is just intoxicating.]
