Have your girl put on a glove (latex, rubber, oven mitt...whatever you have around). The girl will shove her hand up your ass with the glove on. Pull out glove covered in shit. Have the girl jerk you off with the shitty glove. Blow your load in the girls nose. The girl snorts the cumshot up her nose and spits it out onto the glove. Slap the girl with the glove and shout "poopy glove love!"
"Hey want to try The Lovin' Mitt, bitch?"
"Sure, that's legit shit"
