Well, it does depend on how attractive the girl is. If she's cute and at least an average figure, when it comes to clothes, I prefer those short jean skirts and a nice tight top. That's very sexy. We don't see bras unless we're in the bedroom. But if we are, then a slinky short satin gown in white or a bright color is sexy or a push up bra and and very colorful bikini panties. I don't really like thongs because they show too much and they might as well go naked then. I prefer bikini undies cause it's so much fun to slide those down and get my tongue in there and be able to smell all her natural scents on her undies before I start pleasuring her without expecting anything in return. To me, that's what is sexy!
