[The only thing this blond acts in is human. Otherwise? Roxas tends to be who he is in every other context. Why would a vamp pretend he was something else around other monsters? It makes no sense. Then again, Riku was already seeing another side to him that most never would.

He follows Riku in, and before anything can be said, straddles the other boys lap and pushes his head aside to expose more of the neck.]

Don't thank me. This is gonna hurt like hell. Don't move or you'll make the wound worse. I'll bite where you can hide it easier.

[Which means moving the collar of Riku's shirt aside.]
