A Monsters Inc. Avalanche
Shooting cum in someone's mouth and making them so disgusted they force it back up your cock like it’s a nightmare.
I gave my mom a surprise cum shot and she yelled, 'I'm gonna get you back, and I'm gonna get you good!' and spat it back up my cock.
My friend did it to me in the cafeteria and I threw it back up his cock like it was a prank gone wrong.
He did it to me in the car and I made him eat it back up his cock like it was a punishment.
