[Rin has to hold himself back not to laugh at Rei's cute attempts at returning his bite and ruin the mood - but really, whatever was he trying to accomplish with those baby teeth? - so he settles for smirking instead, sharp, ivory tips glinting like they had a conscience of their own, like they were ready to pounce on prey.]

Hmmmm. I can think of one or two things...

[And then his teeth are on Rei's lips again, sinking into flesh and tugging and sucking him raw, making it perfectly clear any plans for dinner they may have been trying to make have just been thrown in the backburner. He doesn't think Rei is too upset about it, either.]

So. Wanna race me to the shower or are you just going to shove me all the way there?

[Maybe he's doing exactly what Rei suggested, too: just telling him what he feels like.]
