So this one is pretty simple all you have to do is fill up on water (safe amount) until your on the verge of releasing it. When you are near the point of no return you have the challenge of orgasming without wetting yourself. This is slightly harder for males so make sure you really have to go. Females should have no problem with this however. Here is the challenge though you have to orgasm while you are pointing your penis/pussy at your face (legs in air etc.). If you orgasm and pee you fail and the punishment is a golden shower on your face. If you succeed then you can choose how to relieve yourself.
This challenge is intended to be difficult so make sure you are on the verge of wetting yourself first who wheres the fun
. If you tried this let us know how it went would be interested to see how it went for each sex.
