Get head from a girl whose mouth is filled with warm nacho cheese (has to be from 7/11). As she blows you, you crunch the nacho chips into her hair and over her body.

You eat a bucket of chicken beforehand and you shit on the girls arm while jacking off. Then you blow your load on the girls arm atop the shit and then you get out your kit and sprinkle cocaine on the shit and cum. Then she takes a pixie stick straw and you make her snort the cocaine and cum should go through her nostril as well.
