This Troper has a friend who comes off as this. You ''really'' don't want to know about some of the things she's fantasized about (many which she seriously wishes she could act on)...

Sounds kinky, what's her number? No, seriously, I've got ''many'' things I'd seriously love to act on myself.

My friend has told me tales of her oversexed D&D character, Pallas, who fucks in order to worship Aphrodite. The general rule whenever they encounter a new NPC? "If we roll over an 8, Pallas ''will'' fuck it."

This Troper. Full stop. If it's adult enough to offer informed consent, and does so...
