Either way, if she's on top of me and very aroused after some good foreplay and maybe already had an orgasm then I seem to go very deep and feel this area squeezing the head of my penis and it feels amazing for both of us. This happened recently and I swear it felt that her entire body was balanced on the head of my cock and she was just going wild to the point of passing out. It was pretty great! 8)
