The Firework 

The Firework is when a girl sticks the wooden part of a firework in the end of the penis and lights it just before he cums, so he cums as the firework launches

Guy #1: Jenny and I did the firework on the 4th of July last year.
Guy #2: I have always wanted to do that.
Guy #1: You should, We are going to do it again this year.
