Musty Finish

Derived from the skill of hitting a musty flick (from Rocket League), Someone involved in sexual intercourse gets very close to finishing, and right as they are about to blow a load, they hit a backflip, stick it back in, and bust inside. Basically Backflipping and busting.

I just hit a crazy Musty Finish!
She asked for the Musty Finish

I want him to Musty finish inside of me.
