What are the reasons a guy would eat a girls ass if they aren’t dating?

Serious question.
Would you eat the ass of a girl that you are only in a friends with benefits type of relationship and if you would explain why?
My friends with benefits asked me could he do that to me the other day and although I’d love to see what it feels like, because I’ve never had it done, isn’t that more so something you do once in some form of committed relationship?
