give me semi public pee underwear cum dare / 18 M

[Mythdare]

I need a good humiliating dare with the items mentioned in the title for tomorrow evening.
I will be going to a forrest after dinner to humiliate myself.
I am new to anal.
I love wetting and afterwards use the underwear soaked in piss as a gag.
i am scared to have cum in mouth or face, I do want to try it but I always chicken out or I don't feel turned on any longer after I cum.
scared to be seen or for someone to find out.

Try to base it on my likes and title words.
But do make it a hard and humiliating and disgusting dare.
