" I love you too, son, and you know my body is yours, whenever and however you want it." Turn over then, Mom, and stick your ass in the air ready for ...my cock."I was shaking as I got myself up, and knelt on the bed with my butt sticking up. Shaking partly from excitement, as I so wanted to feel my son's cock in my ass, but partly from fear of the same thing. It was something I'd never done, another big taboo that I'd be breaking, and I'd heard it could hurt."Don't worry, Mom, I've got some lube,. ”I just smiled as she climbed into bed with me. She said, “Gillian said that after our double-ended dildo play last night that it shouldn’t hurt any. Can I be on top?”I replied, “Yes!”So Betty Sue climbed over me, held onto my cock, and lowered herself onto it. When she was well seated she said, “Okay, you can come in now.”Carrie was holding the video camera and Gillian was taking still pictures. The covers were thrown off and Betty Sue was smiling as she bounced up and down on my stiff rod.. She have very black hair and black eyes. she have dimple in her cheek.She always have smiling face. overall she is gorgeous and sexy chubby women.Very very attractive.She is staying alone with her son.Her mom will come and go for every two months once.I am in ground flour. She is in first flour. We used to talk when giving rent and paying bills. Thats all.No other conversation.Whenever I go to dry my cloths on roof top.She will smile when I see her.That smile will make you to go crazy on. Or is that peeping Tom? What else have you seen or heard?” releasing my fingers she walked over to the screen and leant on the desk staring into Janey’s room.I held back, unsure and guilty about the incidents in the middle of the night. Mel didn’t seem overtly bothered that I was spying and masturbating over my sister. But, I had to wonder what her reaction would be to Janey and her friends playing with my cock and then Janey returning again to play with it by herself and then last night.
