You're incorrigible. Or encourageable.

I listen to River play piano. She finishes. Lays down on the piano bench. Legs crossed, knees pulled up. "You're giving me ideas." "You're incorrigible. Or encourageable."

"I get the feeling we're going to be doing something tonight to take advantage of your lingering effects." "I don't want to think that we're going to do it all the time just because I've taken some stuff. But if we do it I'll give you a handjob."
