Introduction:

I cross the line with my son.

It was a warm spring evening and I found myself at home alone. My daughter was spending the night at a friends house and my son was at a party. He had just turned 18 and was a senior in high school. He and his classmates would be graduating soon and going off to different colleges or jobs. I was a little restless tonight and not sleepy so I decided to wait up for him. I was dressed for bed in a thin cotton tank top and cotton lounge pants. I had a couple of glasses of wine so I was feeling good and relaxed.At this time I was 37 and I had heard some of my son’s friends use the term MILF when talking about me. I’m 5′ 7” and weigh about 120 lbs. I have 36D tits and an ass I keep in shape by running almost every day. I take pride in the way I look and I admit that I do tease those teenage boys now and then. I have been divorced for 4 years now and like it that way. My kids and I have a very open relationship and can talk about anything. My son has walked in on me changing or getting out of the shower and I have done the same thing to him. I think maybe that’s why I am a little restless tonight.

He had decided to use my bathroom to take his shower before going out. I walked into my bedroom just as he was drying himself off. As he walked past me to his room there swinging back and forth was his huge cock in all it’s glory. I couldn’t help myself and I had to stare at it. It was at least 9 inches long with a very large head. I had seen it before but for some reason the image of him walking by me naked with his big cock swinging back and forth like an elephants trunk was stuck in my head. He was in great shape having played football and powerlifted. He was 6′ tall and about 200lbs, all muscle.

As I replayed that image in my head and sipped my wine I noticed my nipples were rock hard and poking through the thin fabric of my top. He was so sexy I couldn’t help but get turned on. I don’t think I could ever act on it, but if he made the first move I am not sure I could resist him. We had always teased each other and at times I could almost feel some sexual tension, but I wasn’t sure if I was just imagining things.

It was almost 1am when I heard the garage door open. He came into the den where I was sitting on the couch. He had a big smile on his face and I knew he had been drinking some. After having some wine I was feeling good too. He came over and sat down next to me on the couch. I turned towards him tucking one leg under me.
