double penetration 

A sexual act in a threesome that includes at least two males if heterosexual. In the threesome, the two males enter the vagina (heterosexual) or anus (homosexual) at the same time and two guys literally screw the one on bottom at the same time.

Met this real hot girl online last night just before bed. I just wanted a quick booty call and when I got there...there was another player there and she begged us for double penetration. That was one of the hottest experiences of my life.
