Laws of Masterbation

1) you may only jizz on a guy if he is dead or unconscious.

2) You may only jizz on a girl if she is alive and conscious.

3) you may not jizz in front of family members

4) you may not jizz in front of a guy unless both of you are jizzing on the same girl.

feel free to add more.

Dude, you just broke the first and third laws of masterbation by jizzing on your dad!
