I have a button and my partner and I find it hella hot. Whenever I'm starting to go try or for one last burst of self-lubrication, all he has to do is bite one of many tender areas as hard as he can (inside of the thigh, breasts, or inside of the under arms). If he does it once so there's a bruise there, all he has to do is basically grab that bruise or dig his thumb into it and the floodgates open and I'm basically ready for anything. It works every time, without fail. It's practically a faucet. And we both just smile as he makes jokes about what a little masochist I am.
What are your "buttons"? Kinky or not? Does anyone share mine?
