I pleasured myself in the bathroom at school once back when I was in high school. This gorgeous girl on whom I had a massive crush (at the time) was sitting in front of me at her workstation in the computer lab. The back of her jeans was so low I could see her thong string and some of her gorgeous behind, and I just couldn't help it, so I excused myself, booked it to the nearest bathroom, and shook hands with Mr. Johnson. Damn, she was fine!
