After gym class I had an idea. I gathered a few of the other kids from the class, and brought them into the girls locker room. I had promised to show them how I got off, without the help of a man. They sat and watched intently. I hadn't put my underwear back on after class, so my hand went easily under my skirt. I had my shirt unbuttoned, and was plucking my nipples, and playing with my breasts. I was playing with myself, caught up in the moment, not realizing that I was making noises. You had been next door, taking a shower when you heard me.
I was rubbing my clit furiously, and pumping two fingers in and out, in and out, of my pussy that was getting wetter by the minute. I applied more pressure to my clit, and pumped faster. I was close, but I needed a small push to get off. I was tossing my head back and forth against the wall, when I saw you. You had heard my noises and come into the bathroom to find the source. All you had on was a towel, and I could tell that you were enjoying what I was doing. You were trying to hide, backing up behind some lockers. I saw that you were putting your hand under your towel to jerk off. I got so hot thinking about you watching me, and getting off on it. That was the push that I needed. When I came, the audience that I had assembled applauded, it had been a great show. I could see that the girls had enjoyed it from their looks, the boys were getting erections. I had been a hit.
You hadn't noticed the others, and in fear of getting caught, you demanded to know what was going on. You sent everyone but me back to class, you told me to meet you in your office. You went back and changed before you met me in your office.
I was sitting in your chair when you came into your office. All you had to say was "out" and I moved. I pressed up against you as you brushed past me, liking the friction on my skin that was still sensitive after my orgasm. You told me to sit down in the chair in front of your desk, we had to talk. I sat down in front of you, and made no attempt to hide the fact that I hadn't put my underwear back on after the show. My legs were open, and I could see that you were trying not to look.
