Boner in class
Once, when I was 12, I copped a hard-on at school, during history class. This was actually pretty common for me, except this time it happened right before the bell rang and every one was getting up to leave for home. I set at my desk until all the other kids had left, but my history teacher was still sitting at her desk, looking at me, wondering why I hadn't left. She asked me if something was wrong and I said no, but my face was beat red. She got up closed the door to the classroom and then walked over to my desk, and set down on top of my desk, with her dress draped over with her upper thighs exposed to me. I could see her panties clearly outlining her pussy lips. My cock was now so hard I thought it was gonna bust through my blue jeans. She asked if I had a problem she could help me with and again I told her no, but she knew something was up, literally. She reached down between my legs and started rubbing the bulg in my pants and smiled at me and told me not to be embarrassed, because most boys my age have erections at school. She swung her legs around so she was directly facing me, on top of my desk. She pulled up her dress and slid her panties to the side so I could see her pussy. It was the most awesome thing I had ever seen in my life. She started rubbing her pussy while she continued to rub my cock. I came in my shorts in less than two minutes and she continued to rub herself for a few more minutes till she came. She then stuck her dripping wet fingers to my lips and told me that I must never tell anyone, or she will get me into the worst trouble in my life. I promised her I would never tell, and she told me if I ever had this problem again that I could come to her for help any time. I stayed late after class many times after that. She taught me everything there is to know about sex that year. Sadly, she moved away the next year. She was my favorite teacher ever.
