During my high school years I turned out to be the top girl-athlete in the sprint items, but my favourite subject was chemistry. We had a new teacher in the 11th grade who arranged the laboratory different so that his desk was at the back of the class and to maintain discipline amongst the boys he had them all in front at the black board with us girls at the back. He had the habit of moving among the rows to check on our experiments and standing behind us watching our progress. Our class was equipped with those bar-type stools with no backrest. At times he would lean over to point out something important which resulted in him making contact with our backsides. We all became used to this method until one day when I felt him pressing his crotch against me. I was stunned at first when I realised he had a hard-on and was softly pressing and rubbing it against my butt and I blushed and was too embarrassed to react. I just sat there and tried to concentrate on what he was trying to demonstrate on my bench. This took only a few moments before he stood back and went on to the next row. I was so glad that my position was in the back row of the class and nobody else noticed.

This continued throughout the following weeks and he became more bold every time he stood behind me. Sometimes he would just stand and pretend to watch my experiment and for several minutes I could feel his hard-on rubbing against me. Fortunately he was very discreet and none of the others were ever aware of what was happening right there amongst them. Then one day he asked my to stay behind when the others left for mid-morning break. The moment we were alone he locked the door and asked me to bring my refrerence book to his desk. He then asked me to place the book on his desk and to place my hands beside the book. In that position I was bent over slightly. He took position behind me and the next moment he gripped my hips and I could feel him rubbing up against my buttocks. He clearly had a huge hard-on. Soon I sensed him fumbling behind my back and the next moment I felt his warm naked penis between my legs. He was soon breathing heavily while pumping furiously and within a minute he suddenly pulled back and I saw the cum dripping on the floor.

That happened only on that one occation. The next year he was promoted and left for another school. Now, 20 years later, I still wonder if I was the only one of his pupils to get "the treatment".
