It's not like there aren't sex acts he enjoys more or less than others. That's just personal preference. And, most importantly, it has nothing to do with how much he and Chikusa mean to each other.

"We can do other stuff, stupid kappa. You could've just said." And he nips at Chikusa's throat, half as a punishment and half in affection. "What do you like better? You could fuck me, byon."
