when somebody sticks an object up your butt. it could be a tongue(rim job), finger, thumb, fist, dildo, vibrater, hamster, lava lamp, beer bottle, dick, anything will do.

When a girl lubes up a guys cock and gently grinds her ass cheeks on and gets him off. That or he lays his cock between her ass cheeks and strokes away without penetration.
Stacy has such a soft sexy ass. I love it when she lets me lube it up and lay my cock between those cheeks and grind on it for a great ass job.
