Tommy was now fully erect and twice the size of his dad even in his younger days. Mary adjusted her position so her son's cock was rubbing between her... pussy lips and clit with every thrust. Then it happened. Tommy's cock slid inside his mother's pussy. Just the head at first but as Mary pushed back she could feel a good 4 inches of her son inside her, with much more still to go. Surprisingly she felt no guilt and felt completely natural, knowing that if he woke she could pretend to be asleep.. My wife said that I would be happy to help with anything that I could. I said of course, and that seemed to make the girls very happy. I told my wife later that night how it surprised me when she volunteered me. She told me that she felt sorry for them. She said that she didn't think much of it and rolled over and fell asleep.Time marched on and true to my word I did help when needed. I always referred to all three of then as "the girls" it seemed natural. At first I felt a little guilty, the. However, I had fears. Fears that I would not be able to stop, once I started. Fears that I couldn’t stop at just getting a blowjob or even being able to fuck such an amazing gurl. I feared that I would be unable to control myself and would have to suck and lick her cock and balls. Fear that I would want to taste her cum. Mostly, I feared that I would love it.Isn't that exactly how an all consuming addiction starts? First, it’s just a curiousity, just a taste. Then another, and another. I had to. She gasped and then thought to herself that this would be a night she would never forget, no matter what happened. As she caught her breath, she realized the stranger was no longer touching her. Was he standing there watching her as she drown in ecstasy? Was he preparing for the next event? She wanted to tear the damned blindfold off but she hadn't been told to do so. She wondered how and why she was so quick to submit to this? She was a strong willed, independent woman, yet she willingly.
