Roll a d20 until you get a 20. Every time you don't, slap your balls that many times. Attach a clothespin after every roll.
Roll a d20 and wait that many minutes. Do not touch your dick at all.
Edge yourself one time. Stop.
You may orgasm now if you can. You must lock yourself in a chastity cage. You cannot use a vibrator, wiggle your cage, or touch your dick through your cage. If you can cum following those instructions. You may. You may not orgasm any other way for 36 hours.
