reverse-spitroast
A three way sexual position. The man lies on his back while one woman rides his cock and the other woman gets eaten out. Usually (but not always), during a reverse-spitroast the two women are facing towards each other so they can make out and play with each other's boobs while the man is fucking them.
Those two girls just invited me over to their place and told me to take a shower first. I'm pretty sure we're gonna have a reverse-spitroast.
