Whoopie Cannon
After cumming inside her, with her ass up, fill the vagina with air like a balloon with your mouth; next

anal doggy style, thrust once in all the way and shove your balls into her vagina as far as possible, then you both fall forward and the massive queef will blow your balls out with force making a whoopie cannon.

Damn dude may nuts is killin me!

Why’s that?

I got mah bitch drunk enough to try the whoopie cannon last night
