Well, I don't think it counts, but as a young kid, I remember kissing a cousin.
But more recently, there's another much younger cousin I have. Geez, I remember when she was *born*. She's about 23 now & lord...this girl has a set of boobs bigger than life. On more than 1 occassion, I've fantasized about having my way w/ those tits. Would never *do* it, but man....
