Back when I was a sophomore in highschool my friends mom, Mrs. Ellen was also a teacher at our school. Being in her mid 30s, 34/35 at the time, she was considered a milf among the guys so my friend was often teased about how hot his mom is. Sometimes if I hung out at his place too late I would stay the night and that happened. Well I went to go tell his parents but when I knocked and walked in after not hearing a response for awhile I came into see Mrs. Ellen riding her husband, eventually doggy style, and on her back. Whole time I was quiet shocked but mentally saving the moment while I didn’t notice I was rubbing my cock. Eventually they noticed and got startled when her husband slammed the door.
I apologized next morning saying I only just walked in but I lied seeing whole thing. They forgave me but her parents and I had awkward vibes around each other for awhile.
