I just read 'After the game'. It brought back memories of the most erotic thing to happen to me ever. This was last year.
I was alone in the changing room because I had deliberately skived off PE at college. I never really enjoyed PE, but sometimes I used to skive it because I liked masturbating in a 'daring' place.
So this day I was alone and had wandered around the room shedding clothes until I was just in my panties. Although I (thought at the time) was not lesbian, I used to pretend that the girls were watching me or even, on one ocassion I actually picked up another girls panties and smelt them. This time I just lay on a bench with my head on a girls skirt. I imagined I was lying on her lap.
I closed my eyes and slipped my hand into my panties. I was getting into it when I heard a sharp voice. 'You disgusting little bitch.' It was one of the female PE instructors! She looked really angry too. I snatched my hand out of my panties, but it was obvious how turned on I was, if you know what I mean.
Anyway, she walked in and said 'Well? You might as well finish yourself off. Put your hand back.. I SAID...PUT YOUR HAND BACK' I was scared so I did it. She sat near me, she was wearing a short pleated hockey skirt. Her voice became softer but still with a powerful edge to it, and she told me exactly how to touch myself. I orgasmed hard and when I had finished she took my hand and made me touch her between her legs, she felt damp. I didn't want to but as I got into it I felt really sexy.
Feeling her cum on my fingers was great and we actually ended up snogging. All the time she called me names and verbally abused me. Know what? I LOVED it.
