I haven't done this for years but it works great. Scope out the local dry cleaners for a good looking babe around the college age. I used dry cleaners because they usually do not have cameras. Call from a public phone asking if you can exposed yourself to her for a college frat prank. They will either hang up or be interested.... Tell her it is totally up to her, that you just do not want to get in trouble. If she agrees you have it made!. I would not jack off for 2 weeks + saving up the big load for them. Be fore I would go into the store I would sit in my vehicle, tie my balls so they were stretched down, pre lube up my cock and stroke it for 15 min prior to get really worked up. Then I would jamb the hard cock into my pants and walk in. Tell the girl I was the one that called about the college prank and ask if I can do it right here. She would say ok. I would unzip - my cock would be half hard and I could start stoking right away. It only would take about 1 minute to blow my load all over the counter. They can not keep their eyes off your cock. I think they expected me to walk in and just simply flash them and leave. By the time they see you stroking your cock, with your tied up balls bouncing they are not sure what to say. I have done this same thing at tanning salons & small thrift stores. Any where a young girl works that does not have cameras. I m getting to old now where I do not pass as a college student.
