When a Girl is giving a guy a Hand-Job and right before the guy is about to blow his load or cum, she punches the guy right in the testicles.
"It really sucked. I was so excited for her to jerk me off and she finally did...I got the Hairy Knuckle Airbag."

"Oh yes, yes make me...AHHH...." *hairy knuckle airbag*

"Bitch gave me the Airbag!"
