The act of eating Cheetos or any other cheese-coated treat, and then rubbing the cheese dust on your balls.
After a fine cheese coating, masturbate and coat your balls with a delicious semen glaze.
From there, dip your balls into the anus of your lover.
When my girlfriend was asleep, I decided to finish off her bag of Cheetos, as well as myself. Perfect time to give her the old Lumpy Pumpkin.
