Mom and the Landlord

Our landlord lived in the apartment upstairs in our building. One day I came home from school and walked in the house. I was on my way to my room, and I looked in the living room and there was the landlord sitting on the couch with no pants on and my mom was topless kneeling between his legs sucking his cock, they didn't seem to hear me come in, so I just stayed aside and watched them. I didn't know what else to do. Seeing my mom like this was so strange but exciting, I couldn't stop watching her licking and sucking his cock. She certainly was enjoying herself, I hadn't seen an adult's cock before other than my dad's when he would occasionally be playing with it, and I would walk in on him. The cock my mom had in her hand was huge, I could see why she would want it so bad. She looked like she was insane sucking and stroking that big cock, I was so excited watching my mom I was jerking my cock to the rhythm of her head bobbing up and down then he let loose with a load of cum that filled her mouth and went on her face. Mom kept saying "thank you, thank you I want your cock and cum so bad". I shot my load in my hand I had cum so much and so hard my balls hurt. They never knew I saw them (at least I don't think so). But I thought of my mom in a different way after that day, I would jerk off thinking about her sucking my cock and sometimes I would jerk off thinking about me sucking his big cock.
