I was with two other guys in a restaurant and the dividing wall next to us was half wood, top half glass. A couple sat over there and the guy just sat there eating while she sipped a drink and talked dirty. She was like, "When you take me home, I'm gonna ride your face until you come in your pants. I'll suck you off until you're ready and horny and then I'll make you eat my ass." And a few other things.
When they got up to leave, the guy had a huge boner in his pants and all three of us did too!
