underhanded fastball

Jerking off in a public restroom stall while doing a handstand. The ejaculation must take place in less than 15 seconds after the jerking commences, and to truly perform this dead the load must be caught in the mouth of the one jerking off.

Dude I passed this girl walking through the mall yesterday. I got so hard I had to go into sprint to the restroom and pull an underhanded fastball.
