Mall dare for females - clothing store
 

Do you have a pair of old, frayed, stained panties you usually keep for wearing during your period? Well, put them on.

First, go to the toilet in the mall and masturbate while wearing your panties until you cum.

Now walk in to a clothing store (preferably one with male staff), select something you want to try on, and go in to a changing room. Take off your panties, hang them on the hook. Leave them hanging there when you exit the changing room, and leave the shop.

Come back in half an hour and tell the staff you forgot your panties in the changing room and ask if they found them.

For extra points - put the panties on right in front of the staff
