What should I ware?Nice and easy, go out to your local mall or park then remove your panties. Just drop them on the floor then pick em up and carry em around for the next hour. You're not allowed to put them in a pocket etc, you must keep them in your hand.
See this great example to see how it's done.
What do I ware?Find a semi busy male public washroom with multiple stalls. Sneak in quickly remove panties and bra then put them out side the main bathroom door then pick a stall to masterbate and bring yourself to orgasm. Once your done exit and retrieve your bra and panties carrying them home in your hand.
