Punishments.
This is a very easy and hurtful punishment. I was punished like this earlier this week. Its a kneeling punishment. All you need is a small bag of rice and two shoelaces. First lay the rice into 2 small piles on a hard floor. Then take the first shoelace and tie it around your cock. Then take the second shoelace and tie it around your balls. Then sit on your legs and tie the shoelaces to your big toe on each foot. After finished tieing Rise to your knees and kneel on the rice with your hands on top of your head for 15 minutes.
