Ass buckle

An "ass job", where a guy fucks a girls ass cheeks, without penetration, and in order to increase friction the girl will lower her belt down around her ass to squeeze her ass cheeks together to make it more pleasurable.

She put on the ass buckle for me and I was done!

Ass buckling

When you tighten your ass to the point where you feel immense pain.

Did you hear Gabe’s ass buckling last night?
