I'm both a gymnastics coach and math teacher in High School and most of my students were then in their early to mid-teens. I had been there a couple of years without an incident of any kind with all students well behaved, all but one.

Sandy, (name changed) one girl that wears very tight, torn jeans and loose blouses, kept up a major effort to get noticed by me and after a time it got to be burdensome. For one thing, it was hard (forgive the pun) to stop looking at her. What she had in her youthful body parts stuck out and was noticeable. She made it her business to sit in the front row with a big, Cheshire Cat smile on her face.

She knew what she had and was offering it, wordlessly. I kept having visions of ending up behind bars so I watched myself carefully and said as little as possible to her. In time, she became bolder and bolder. Finally, when she could do it unnoticed, she would whisper small sexual provocations. After a year, she stopped wearing the torn jeans and wore flared skirts, some fairly short. She would part her knees enough for me to see that she was shaved to a smooth and clear camel toe.

I began to have involuntary erections and her eyes were focused on my crotch. I asked her to stop her attacks and she would whisper back, "Don't be silly, you want me so badly."
I kept wondering where this teen got her boldness and energy but mostly I avoided her. Then came the day when she was pure brass and guts. She sat inside the podium on my math class and I did not notice her there, walked up to it and opened my notes to start my lecture.

At first, I felt her hands on me and gasped out loud but feigned a cough to get through it with the class. In a few minutes, she had my erect cock in her mouth and was moving on it. I felt several different emotions, struggling to concentrate on my lecture subject without a much needed blackboard. Sandy knew what she was doing and I felt her writhing tongue underneath my erect penis even as it was in and out of her mouth.

When my orgasm came, I almost passed out and actually heard Sandy gulp and gasp. Unable to move from the podium, I gave an assignment in geometry and released the class early. When the room was silent, Sandy whispered, "Are they all gone." I said, "Yes, they are." Finally looking down, I saw Sandy inside my podium, fingering herself. In a shaky voice, she said, "There, that was not so bad, was it?" Then, I heard her release and gasp.

After that, she began to slip into my apartment at odd times, but remained unnoticed, and we had so much sex I did not believe it was humanly possible. I began to have strong feelings about Sandy but soon she was graduated from school and went away to college. We saw each other one last time in the city where she went to college and then our time and history was at an end. I never met anyone anywhere near to Sandy, at every conceivable level, but in the ensuing years, I missed her terrbly.
