This is hot. I think all straight men should try this. Its just like frottage, but deep inside a vagina. If you're the guy at the bottom, your buddy's cock strokes will tickle against your under-shaft and when combined with the contracting vaginal walls, the sensation will be the most intense. Now would it be too much to ask for internal creampies from a double-dicked pussy fuck? I've always wanted to see two men shoot their loads while each inside a pussy, and see it ooze out. HOT!
