whale threesome

The act of having sex while you or your partner is laying on a friends back. The friend serves no sexual purpose other than to hold the two of you up.

The other night, after Scott fell asleep, my girlfriend and I had a whale threesome with him.

Cosmic Threesome

When having intercourse with a pregnant woman, the booty hole of the fetus aligns with the vaginal opening, causing a threesome to occur.

Man, I just had a wild cosmic threesome with this chick who was 8 months pregnant. That shit felt wierd.
