Fapping Out In Public

I went to this open area near the railroad tracks to take pictures in my skimpy shirt and thong panties. I got caught by 2 guys on bikes and 2 other guys too. That got me really horny, so I went to the side to sit down, took my thong off and started masturbating while edging. At the end, a couple walked by. The guy tried not to look but his cute girlfriend did look and just made made me cum so hard
