My mother came home early from work and she caught me sucking on my grandfather. She walked right in on me getting him to c**. She said what the hell are you doing. I stood up so fast and left the room and came into my owe. I could hear her telling my grandfather to put his pants back on. Then she came into my room and asked me why was I sucking him off. I told her that I was just curious about being with another man. She said are you gay. I said I dont know mom. She asked me how long have I been sucking him off. I told her about 4months now. She said as long as he has been here. I said yes. I told her that I talked him into letting me do that to take his temperature. My grandfather was very senile and accepted that I told him that’s what the doctor wanted me to do. I told her there was days that I would s*** him twice a day. She told me that she was going to tell my dad when he came home. I told her that dad already knew that I was doing it. She said what and I said dad had caught me and told me not to anymore. But I liked sucking on him. I asked her not to tell dad that she caught me sucking him again. I told her that I wasn’t hurting him at all. Then she tells me that your father did that to him when he was young. Then I told her that dad has been sucking me off and f****** me too. She asked when did your father start that. I told her the day he caught me. For about a month now. She was mad at first and then she said that he shouldn’t be doing that. She said that she is going to get back at him and have him catch me and her having s** together. He was going to be home soon so she left the door open and we started f****** and dad walked in on us. I started c****** inside her and then she got up and went into the bedroom and I could hear them talking about it. Then my dad came in my room and sucked me off with mom watching him.
