Must be a public restroom with multiple stalls. Remove everything except your shoes. Sit on the toilet and masturbate until you are edging. You must continue to edge until someone else enters the restroom. You may only cum as soon as someone else flushes. When the sound of the flush stops, you must stop touching. You may try three times. After each failed attempt you must switch stalls, walking naked between the stalls. If you haven't cum by the third attempt give up. Go home and practice your edging.
