So, at the beginning of the year we hear that we get a new, young chemistry teacher, and as the first lesson starts a 25 year old woman walks in.
She was wearing a sweater, showing some cleavage and way too tight jeans. Immediately I felt something down in my pants and seeing the other boys in the class they saw it too. This was the most sexy woman at our school.
As such the year went on, with all the boys trying hard to keep their concentration at chemistry. We did notice tho, that this woman had a certain attitude towards us. She had some of these special looks sometimes, walked around aware of the fact that people were looking at her ass and made certain comments with a hidden but clear sexual undertone.
So one day, after the lesson, I asked her to help me with a certain problem. During this I noticed she was flirting with me, and very touchy. She started with her hand on mine or my shoulder, but as I, horny teenager that I was, flirted back, she went on to my stomach and even almost touched my crotch.
