Bending

A form of anal sexual pleasure specific to people who have a very large penis when half-hard. This act involves edging oneself almost to sexual completion, then waiting till the penis softens up to a point where its hard and virile enough to ejaculate, then bending it into the anus, therefore finishing in your butthole.

Friend 1: Dude I was Bending all night, it took ages to shit it out!
Friend 2: That's insane, you should be in an asylum!
