Mutual Masturbation At School

This happened eleven years ago when I was a senior in high school. My best friend Lisa and I were talking during lunch. I told her about an article I read in an adult magazine. A woman in the article said that she likes to masturbate in public places like on the bus or in a movie theater. She told me she had always wanted to try that. I was very attracted to Lisa and I often jerked off to her yearbook photo. We agreed to meet at the school during what they call 'Homework Center.' In Homework Center, there are a few teachers that help kids with homework. We met under a set of stairs that no one used at that time of day. I told her she could go first. Lisa lifted up her skirt and pulled her red bikini panties off. My cock got rock hard. As she was laying there on the floor fingering her gorgeous pussy, I unzipped my pants and released my cock. I was a little embarrassed because it is only about 5 inches when it's hard. I unbuttoned her shirt so I could see what her tits looked like. I undid the hook on the front of her bra and rubbed her tits. After a few minutes of doing this, Lisa started to shake. She grabbed my hand and placed it next to the fingers that were in her pussy. She said 'I want you to feel me when I cum. As soon as I touched her she had an orgasm. She came so hard she started to pee. After Lisa stopped cumming she told me that was her first orgasm. I started stroking my cock while she watched. When I was about to cum she put her mouth by my cock. She wanted to swallow me cum. We got together and did that a lot more before the school year ended. We even taped it so we could each have a copy while she was at college.
