DESCRIPTION
I think there's a name for this:
Motorboating (verb)It means the activity of putting one's face between a woman's breasts, and rocking turning one's head rapidly from side to side while making a noise like a motorboat."Put your head between her tits and go bbl bbl bbl bbl..."
(from Urban Dictionary).
This variation is called "Ass Motorboating", and it has the same meaning as a regular motorboating, just adjusting the object of the motorboating to someone's rear.
