Bring a bag of extra clothes with you to a public place where there is a public bathroom with at least 2 stalls with doors that can be locked. First, hide the extra clothes at least 50 steps (meters) away from the public toilet. Walk into one of the stalls and put all your clothes in the bag, now you're nude! Open the door and put your clothes on different locations in the the bathroom, all items of clothing in different places visible for everyone who might enter. Then go back into the stall, lock the door, and your mission is now to cum 2 times in the stall. When this is done you may get your clothes back (if they still are left). If they are missing you have to go finding your hidden clothes, you may make clothes out of toilet paper if you like to get there with any clothes on...
