dirty zo
Where he grabbes the back of your head and shoves it as far down his penis as it will go making sure your gauge reflex sucks and your eyes are watering, meanwhile he's fingering you with a strap (revolver) instead of his fingers
My lady love when I dirty zo her it's one of her faves although she can't be dirty zo'ed all the time, I gotta make love to her once in a while;)
