wobbly waterfall

A really weird sex position where the male, or penetrator, is laying off the edge of the bed so that his penis and torso are still on the bed but shoulders on the ground. The female, or penetrati, inserts the penis into their preference of orifice. The female holds the male with her legs and has full control over how deep of a penetration she would like. The wobbly part is just the dumbass penetrator wobbling on the ground like an asshole.

Guy 1: Yeah I tried doing that waterfall sex move on her but I was so unstable
Guy 2: lol you hit her with the wobbly waterfall
