I work as a builder. We are working at a local high school. The other boys had left and I was locking up one evening when I heard something coming from the resource room at the end of the hall. I thought it would be my work mates hiding to jump our and scare me so I decided I'd get one up on them and sneak up on them. I quietly made my way to the door and then flung it open loudly and quickly. What I walked in on was not what I expected. There was a teacher lying spread eagle on her desk with a boy around 16 standing up plowing her pussy furiously. When they heard me enter he pulled out quickly to face me. He must've been almost done because as he pulled out beads of cum came flying from his dick. Some shot right over to me and landed in my shoe. He grabbed his pants and ran without a word half naked into the corridor. I said to the woman what the fuck is this?? She begged me to pretend nothing happened. She said she will lose her job her marriage and might even go to prison.
She has been fucking me every day in return for my silence. Even tho the sex is amazing I wish I wasn't caught up in this.
