Nothing too rough, violent or degrading, but yeah, definitely; being the sort of ovaries-to-the-wall type that Rei is, I could totally see her handcuffing me down and saying things like 'pffft, that made you come? Already? You lightweight.' Naturally, I would want her to keep going until I fainted...
Given that she's part tiger and probably preternaturally strong, she could probably break me and heavens, how I'd enjoy it ~shiver~...
