It was very apparent to my mother how much I liked what I saw. Then she slowly reached up with one hand, grabbed my hand and pulled it off of my cock.... My cock was twitching like crazy wanted to unload my massive build up of cum. Then with her other hand she hesitantly grabbed my cock. My mothers hand was soft and warm. She had such a gently but firm touch as her fingers wrapped around my throbbing, messy cock. Then with no words still being spoken, she began to jerk me off! At first she. After a couple more up and down movements I widened my legs and felt the skin rip, as I started to cry granddad reached up and gave me another passionate kiss which when he was done the sensations between my legs were like electric and we started to quicken the pace. As the orgasm hit me I was bouncing up and down on the full length until my back arched and granddad drove it all in and spilled his seed into me, I sank onto his body feeling exhausted but amazing at the same time, as his cock. The force was mild but already, I saw some tubes filled with creamy cum being sucked up the tubes. Charlie was really enjoying himself, his eyes were closed and he was arching his back upwards as if someone was giving him a blow job. No matter how aroused I was, the machine has got to work harder, because I was not feeling enough to ejaculate. The machine seemed to have read my mind, a light green viscous liquid was released from the container on the ceiling into selected tubes, I was one of. .. for ages. When he did get to my breasts, it took him an eternity to get to my nipples and I couldn't hold in the groans and gasps that forced their way out. His eventual arrival at my labia and clit produced the first orgasm I'd ever had other than through masturbation. As soon as my ... convulsions died away he did it again ... and again. The third time, I blacked out for a few minutes. When I woke, I was untied, I could see and I was in his arms. He entered me as soon as he was sure I was.
