That was as clean an invitation Finn could manage without attaching any pressure - maybe Poe would take it and maybe he wouldn't, but either way it was at least out there in the open now. If Poe wants to keep what they have as strictly platonic, all he has to do is--

--not sweep in and kiss Finn like that. Finn gives what can only be described as a groan and scrambles up to a sitting position to be level with Poe. It means breaking the kiss but he kisses right back, a little sloppy but enthusiastic as anything. This one is quick too, though, because he breaks it off again to look, concerned, into Poe's eyes. "This is really okay?"
