[Daruth]

If you do it in a public toilet, then you must go into the stall, pee through your underwea then leave with the underwear still on.

If you do it on a walk or something similar, then you must get a water bottle and fill half with water and half with pee. Make sure to take frequent drinks on the way! You must finish the bottle before you get home, if there is any left in it you must pour it over your head before you enter the door.

If you do it somewhere hidden other than a public toilet then you must go into the hidden place, remove your underwear and put them in your pocket and insert something into your ass before leaving.
