A horny potato
The ‘69’ position but both people are using their butts instead of their dicks. It’s like a butt-fuck for the people who can’t handle the real deal.
I told my girlfriend we were doing the 69, but I just pulled out my butt instead of my cock.
My buddy and his friend were doing the Horny Potato and I had to leave the room.
My mom walked in on me doing the Horny Potato and she said, ‘I didn’t sign up for this.’
