I am the cause of my own situation. What I did was wrong. Mark is my son and was almost eighteen when my friend Michelle and I took Mark and his friend Steve to a water park. Let me put things into perspective. I divorced when Mark was five. Over the years since then, I have dated a number of guys and even a couple moved in with me. I have a very nice body and one of the guys I dated use to like for me to flash. Flashing was an addiction for me. I loved the thrill and loved it when guys looked. All of these guys had another thing in common, they didn't want a relationship, just sex. It was always fun, but after a while I got tired of them being lazy. Mark was an athlete. He was in excellent physical shape and was very attractive. To say that I was in a good place mentally during this time would be an inaccurate statement.

Mark and Steve were in the wave pool and I was watching while sitting in a beach chair at the waters edge. They were having such a good time. Mark got out and I asked how it was. He told me to get in and try it. So, I walked in and went under water very quickly. It wasn't any fun to me. I walked out and back up to Mark. Steve had walked away and Michelle was in the lazy river. I sat down, put my sunglasses back on and began telling mark that wasn't any fun. A few minutes later a very nice lady walked by and told me my breast was exposed. I figured it might have slipped to the side a little as I was wearing a string bikini, which wasn't a good idea, but I loved the attention while wearing it. When I looked down, my left boob was completely out and my top had pulled up over it. I was kind of mortified, but after thinking about it, I liked it a little. Mark and I jumped up to get drinks when I realized that he didn't say a word. I stopped him and asked if he saw it. He sheepishly nodded yes as he lowere his head. This excited me and I thought I would embarrass him a little. I told him he was a little shit for not telling me. When we were in line, I asked him if it looked good or bad. He didn't know what I meant, so I reached down and touched my breast. He smiled really big and said it looked good. If we were somewhere else when he said that, I would have given him a big kiss. It was all I could do to contain myself.

This sounds terrible, I know it, but it only got worse from there. We were going to leave and Michelle and Steve headed out to the car first. There were outside lockers at the water park. We had the back set, which couldn't be seen unless you walked in and through the other lockers all the way to the back. All I needed to do was put on shorts and a shirt over my bikini. But, I was a little excited and told Mark to see if anyone was coming. When he said no, I took off my bikini top and threw on my shirt. It was very quick, but mark was watching the whole thing. For a second I thought about doing the same thing with my bikini bottoms, but decided that was too much even for me. As we walked to the car, mark asked me why I didn't take off my bikini before I put on my shorts. As I smiled at him, I told him I thought it would embarrass him. Instead he asked if we wanted to go back in so I could change. I laughed said no. Then mark said I could step between two vans in the lot and he would stand cover for me. I realized I had created a monster. I really thought about doing it, bud didn't.

The rest of the summer before mark left for college he made comments to me like he wondered if I wanted to lay out or if I want my back rubbed, topless, of course. It was cute and kind of fun. I think during this point, we both looked at each other most of the time not as mother-son. I would tease him by going braless in tight shirts or wearing skimpy nighties. We were both having a good time.

Mark and Steve went off to college. The school was only 30 minutes away and they moved into a dorm. I had to work in that same town every Tuesday. I would stop by the dorm and see mark and Steve. One day while I was there, I walked up the stairs to the second floor where they lived. As I was walking down the hall, one of the guys whistled at me. I hurried into Mark's room. In walked the guy who whistled and was trying to say hello when Steve told the guy I was Mark's mom. He didn't believe and began saying I was fine and so on. Steve got up to leave to go eat and it left mark and me in the room. I brought up what they guy said. Mark immediately agreed and began telling me how good looking I was. It made me feel really good. We left and went to go eat. When we got back, Mark leaned over and gave me a kiss. It was more than a peck on the lips. It felt good.

A month later i stopped by and we went out to eat. When we were done, Mark asked me to come up to his room. At first I said no, but he said he had something to give me. We walked up there and into the room. He shut the door and I asked what he had for me. Out of nowhere, he grabbed me and began kissing me. I submitted to his will and we began passionately kissing. Before I knew it, I was laying on top of him on his bed. I stopped to ask where Steve was. All he said is he won't be back tonight. We kissed some more and I finally decided I better leave. Mark was begging me to stay. I asked what would we do. He just smiled and I kept asking what he wanted to do. He finally got up and kissed me and whispered in my ear that he wanted to fuck me. I acted shocked and told him I was his mother. Kind of defeated the purpose of that statement as I began kissing him again. I asked him how would I get out of here without causing suspicion. He said that we would get in bed and have fun then at three or four in the morning, we would get up, he would have me wear a hoodie and I could walk right out the side door. With the hoodie, no one would know who it was. I told him that it would be wrong. He said he would skip all of his classes the next day and follow me home and would could have sex at home. I told him no and left shortly after that. If he would have followed me home, I would have had sex willingly with him, but he didn't. I enjoyed the teasing and the excitement when I was at his dorm, but I knew that if we were left alone at home, we would have sex. So, I hurried up and began dating a guy. Mark was devastated. When I stopped by to see him, he would leave. Steve told me that Mark didn't like the guy I was dating. I knew why. Christmas was horrible. The next semester we barely spoke. Over the summer mark and Steve rented an apartment and Mark only came home one weekend. It was killing me.

A few months ago, I broke up with Sam, who I was dating. I didn't tell mark, but he heard. He was still barely talking to me. On Tuesdays I still was in the same town as Mark. We had a family business where I had to do the bookkeeping and take the money to the bank. I did this every week by myself, but this week, I called mark and asked for his help. I explained that there was a considerable amount of money and I was concerned about taking it to the bank myself. He agreed to help, so I picked him up at his apartment. He didn't speak even though I was talking and asking questions. We went to the business and got the money and took it to the bank. We drove back to the business and I put away a few things. There was no one around, so I went back to the bathroom and changed my top. I took off my top and bra and put on a very thin low cut top. I walked out and Mark immediately noticed. I didn't have to say a thing to him. He leaned down to kiss me, but I was concerned about doing that in front of the glass door. I told him we needed to go in back. My intentions were just to kiss, but he thought I was giving him the full green light. He began kissing me and took off my top. Instantly he unzipped my pants. This was not the time to say no again. I wanted the first time to be nicer than him bending me over a dirty sink and pounding me so hard from behind. He came inside me and I turned around and got on my knees to clean off his cum covered cock. Over the weekend Mark came back. We spent as much time as we could having sex. Neither of us can walk. I know what I'm doing is horrible, but it feels so right.
