2 girls are making out with eachother. they stop at one point and one takes a huge shit into a cup. they then begin to lick the poop like it's an ice cream cone. one of the girls gags herself and vomits onto the poopsicle, then they keep licking it. soon enough they are taking turns vomiting into eachother's mouths while both covered in shit and vomit.
sally: you should watch 2 girls one cup!
suzie: ok! *watches it*
suzie: *commits suicide*
