My father came into my room. He is a tall man, a little over six feet and well built. He was only wearing a pair of briefs. As soon as I looked up, I ...turned red because I could see that my father had a hard-on."Daddy, get out of my room. I'm trying to work." I don't care what you're doing, you little slut. Turn that computer off and come over here to the bed." No Daddy. I need to finish this page before I go to bed."My father crossed the room and tore the computer away from me and threw it. She gasped, but was thrilled at the sight, and called me dirty young man then gave my cock a wee rub through the material. Just for that I have something special for you to put on!Her husband shouted through are you ready, she shouted back ‘yes, start taping’. I came out the room dressed in a black & red satin French maid’s outfit. She spanked me on my arse and said hurry up and see if the chocolate sauce has cooled enough yet. I walked to the cooker, stuck my middle finger in the pot and it. "She clung onto me and I could feel her small tits up against my chest."I could suck your dick," she said in a small voice."Don't even think like that," I said a bit shocked, "you my sister and things like that are not allowed." Why?" she asked pulling back and looking me directly into my eyes."It's a genetic thing," I tried to explain and thinking back to my biology classes, "you and I have similar genes and if there's a rogue gene we probably will both have it so any offspring we have may. "Okay, let's try again. Are you ready?" mom asked."Yeah," I said.But after a while, it was apparent this would still take a few more tries, so I was glad mom had put down the blanket to protect her knees.The fifth attempt after the break was going on when I noticed my balls had started to feel really warm. I moved my legs further apart and shifted my hips a little. I felt mom immediately accelerating the pace when she noticed I was starting to become responsive.I was so close now, and mom's.
