Dick Roulette

Going on chat roulette with a group of friends and taking turns sitting in front of the computer everytime a penis shows up on screen.

When two Lactose intolerant men both eat an entire tub of ice cream then proceed taking turns riding each other's cocks until the rider sprays the ridee's crotch with a stream of diarrhea.

The winner is determined by how kinky the couple is. The loser buys the anti-diarrhea meds.
