reversed lawnmower 

When two male partners (of the gay sexuality) "pull-out" after they have "filled the mower with gas", start to whip their penises in a circular motion. One partner going clockwise, the other counter-clockwise, and end up cumming on each other when they meet in the middle. In this production, please don't wear protection... It ruins the moment.

Thomas: Garry, you look super hot! Let's do the reversed lawnmower!
Garry: Okay, come plow me babe!
Thomas: Okay! My cheeks are spread!
Garry: Prepare for decimation!
