No cumming for 4 days. Every night masturbate until you almost cum, but do not. Throw your hands/fingers behind your head, and go foot sleep.
However, If you can't manage to stop. You must:
Girls, rub your clit with toothpaste after you cum, and time starts over.
Guys, jack off with toothpaste and time starts over.
(what I mean by start over is four days start back)
If you cum again after this(next night) you have to report to me, I will give you another punishment. Enjoy
P.S. let me know if you plan to do this.
