My dad never was, what we call a "handy man", when something had to be fixed at home he called the school janitor, were he was a teacher. Many times the guy was there and my mom was the one who told him what was to be fixed. After some time my mom hired him to cut the lawn and take care of the garden, because my dad didn't care. One day I came from work and caught the janitor on top of my mom, in our guest's bedroom. When I've entered the room the guy stopped fucking her, roll over my mom staying on her side and he didn't even bother to cover his big cock, rock hard and pointing at me. I stood there speechless for a few second and run to my bedroom. My mom divorced my dad and married the janitor. For years, when he had the chance, he asked me if wanted to taste what I've seen inside my mom's pussy. I've always laughed and tried to change the subject, but one it happen, and happen many times after that until he was more than 70 yo, and threesomes with some of my boyfriends. My mom never knew about it.
