Pantsing and Stripping Forums

Every year my co-ed friend group goes on a spring break trip together and we have increasingly funny or humiliating experiences. One year it was strip poler (but only down to bras and underwear). One year we went skinny dipping but everyone covered up with their hands. This year we decided on a no limits prank war, and I need some help coming up with ways to humiliate and get some people into some difficult situations! Open to M or F ideas but focused on F!

Once you all get naked, everyone should get their pubic hair shaved off, by a member of the opposite sex.

A timed masturbation game is good, with unknown reward/penalty for fastest/slowest.

Each female should bring her kinkiest sextoy and then have to demonstrate it.

If there is a place that does public body painting, you should all get naked and painted in some way.

A bar hosting a wet tshirt contest can usually devolve into a topless (sometimes bottomless) performance.

What could we do to whoever cums first? Maybe they have to ruin? Or someone has to choose their outfit every day?

One reward/penalty could be that the fastest/slowest were paired male fastest with female slowest, etc and the two pairs had to 69 until all had another orgasm.

Another could be that the fastest gets to make the slowest cum in some public place like out in the water at the beach.
