When 8-12 guys cum into a mug. You stir the cum with a large kitchen spoon into a thick milky consistency. Then find a funnel-like object and insert the smaller end into a passed out, drunk female's genitalia. Slowly pour the blended substance into the large end of the funnel and place your bets on the poor bastard that gets her preggo. That is how you sperm-roulette a girl.
