Underwearless, his gigantic dick sprang out...and he said THAT'S why he was called BIG Daddy. I thought it was because of his beer gut. HAD to be 9-10...inches,dense black pubes and just incredibly and horrifyingly THICK. I was in awe! He went back to licking her as I TRIED to get his dick in my mouth but I kept scr****g him with my teeth so I just stroked him,licked and sucked what I could until he pshed my head back and motioned my to start licking HER! I had NEVER been in the presence of a. She asked me when did I come I said a while ago when u were having sex with uncle. She smiled and said are u jealous son? I was surprised and said yes. So she said my innocent son come to my room I’ll show u what we both are doing. I was confused and excited at same time. She took me in room and made me sit on bed and she removed her blouse and threw at me. She said see how your mom is fucked her own brother. She took uncle’s cock and started sucking it. Man she was looking so damn hot and. Even if I fuck her, she would not disclose this anywhere as she was very decent and scared.On the 3rd day, I had slept half naked exposing top of my body and my dick had a morning erection. She came near me and looking at my body. She was breathing fast, seems she got aroused. I opened my eyes and saw her, she went out. I went to have bath and didn’t take towel purposefully. I called her to scrub my back, she initially hesitated and finally came inside bathroom. This was the time I was waiting. Kathy offered me a beer but it was too early for a beer it was not even lunch time yet so I said no thank you not right not but thank you. As I was leaving Kathy said to me out of the blue that she saw me and my wife ducking rough out in our back yard, and had to your wife to go along with it. I told her I will come over after dinner and tell you everything that when she stated that we are having dinner at her house be here around 4:00. I told her we will be her and to make sure she has a lot.
