One of my ex girlfriends wanted to try to see how much water she could take in the ass. I probably had about a gallon in her when she screamed to try to put my hand up her ass. After about 10 minutes I managed to get to my wrist. She tells me to make a fist and punch her in the ass hard. All that water was spraying everywhere. Unfortunately it created a vacuum in her asshole. Had to throw her over my shoulder, and call a friend of hers to take us to the emergency room to get my hand out. Every few months she will call to get fisted or see what kind of huge things I can stick in her ass. Her husband hates fucking her in the ass, so she calls me.
