Frances Punch 

A sexual act shared between a man and woman. When oral copulation is occurring and the male is about to climax the female simply gives a quick, firm and hard punch straight to the balls. Similar to a donkey punch but given by the female. Proper execution of the Frances Punch involves a slight upper cut so the male doesn't see it coming.

"Oh Baby I'm about to Cum"
Insert a qucik uppercut punch to the balls and the Frances Punch is complete.
