I met a guy on a holiday and we found out that we lived near each other. He lived with his father because his mother was on a trip. We got in a relationship and after 8 months he moved back to his mother. I started at a new school after I graduated and after 2 weeks he sended me a message that he was home alone so we went to his house and had sex. Suddenly his door got open and we covered ourselves immediately. His mother was back at home and wanted to say hello. She closed the door and after we dressed up I walked to her to apologize. She turned around and I realized that his mother was my English teacher. That was the most embarrassing moment in my life!
