[Rin's eyebrows mirror Rei's, his grin unabashedly shifting into a smirk.]

You're turning out to be more of a horndog than I expected, Rei.

[Not that this is a problem, not in the least. In fact, Rin punctuates that thought by closing the gap between them, tongue already demanding entrance. It's as deep as it's quick, just to leave him with a taste of promise, but he doesn't part without a nip to Rei's bottom lip.]

I could get used to that.

[A devious giggle and another peck to the lips later, the hat sneaks up on top of Rei's head again, and Rin's hands are now free to tug on the straps of his bag before they completely slide off his shoulder.]

Come on, now. [A shrug and he spins on his heels, towards the general direction of Rei's room.] This is not getting any lighter!
