Hot, but kind of funny: They're just the slightest bit off on different wavelengths. He's completely hot to hear her story about getting fucked by another guy, and wants to feel like he's there watching it. She's into him and his cock, and the other guy is a bit of a distraction for her from the actual moment. She can't quite see that he'll get much hotter if she focuses on the other guy for a few minutes and he can't quite see that she really wants to just get down to it with him.
