In all honesty, this happened to me. I had s3x with my English teacher but it wasn't while I was still in high school. This b**ch was actually smart about it. I graduated high school in 1997 and I had turned 18 in April, right before we graduated. I remember sitting in class one day and the she asked which students would be turning 18 before graduation. Four girls raised their hands and only two guys. The other guy had a terrible acne problem. At the time, I had no clue why shes asked this. She ended up having a graduation party for us at her house and ended up asking me to help out after everyone left. I was picking up outside and she asked me to come in and she started kissing me and led me into their bedroom. Her husband was already in there and I was like, "OH s**t!". Apparently, her husband, who was the girls basketball coach, enjoys watching his wife have s3x with former high school students as I found out later in life, this happened every year they were teaching at the school. She even had two football players run a train on her a few years later. The s3x was ok, just kinda weirded out by her husband watching. She had a fairly pretty face, but not much of a body and she didnt even take her shirt off. It was all so much a blur. After I finished, I just grabbed my clothes and shot out.
I think she was probably 33 at the time. She really couldn't get in trouble because I was 18, graduated from high school, and it was in their house with her husband's consent. They ended up having to move away because their oldest daughter, who was 15, had s3x with the math teacher in the back of his car, at school, with another student watching from inside the car. This happened about 5 years ago.
I guess freaks run in the family.
