It was late on a Saturday morning and I was feeling restless. I had just come back from a five mile run. At 41 I took pride in keeping myself in shape. I was in my bathroom and was about to get in the shower. I had dropped the robe I was wearing and looked myself over in the mirror. My legs were toned and long. My ass too was high and tight from years of running. Even my stomach was flat even though I had two k**s. The only thing that was a little out of place were my boobs, they were a little on the large side. When I was pregnant with my daughter twenty years ago they had ballooned up to 36DD and just stayed that way. They didn't sag at all but you could tell they were heavy. They made my running a little difficult sometimes but I was still glad I had them.

I slipped into the shower and enjoyed the warm spray. I soaped up and enjoyed the slick smoothness of my skin. My breasts got me a lot of attention I must admit. Of course I like to show them off in low cut tops and dresses and I even went braless sometimes. Young men and old men would stare at them. Did I tease? Sure I did. I ran my hands over them, across the brown tips of them making my nipples perk up and get hard. I felt their weight and fullness. They were all natural, all me. As my right hand played with a hard nipple my left hand worked its way down lower. Down past my tummy and between my legs. I always kept myself perfectly smooth either by shaving or waxing. My hand found what it was seeking, my swollen labia. I was very aroused and I could not put my finger on why.

My fingers parted my lips and found my hole. Pushing inside with two it felt hot and tight. I was slick on the outside from the soap but also on the inside from something my pussy was producing. It was sticky and slick at the same time and there was a lot of it. I thought about what date it was and I knew then what was going on. It was the time of the month for me to ovulate. Today and tomorrow I would be at my most fertile. Whenever this happened I got super horny and my pussy started to discharge this slick stuff. I guess it was lubricating itself in anticipation of getting fucked.

I found my clit which was big and swollen. Playing with that and pulling on a nipple was going to get me off quickly. I pulled hard and rubbed faster. I felt the familiar fluttering down below. I gave into my orgasm in the shower and had to let go of my boob to steady myself against the wall. I came hard and my knees got a little shaky. I recovered and finished washing my hair and got out of the shower. After I dried off I decided to be lazy today and I put one of my son's big t-shirts on and nothing else. It came down to mid thigh. I got something to eat and drink and then decided to get on the computer in my home office.

I went to a photo sharing site where I had posted some pictures of myself, some clothed and some naked. I loved to read the comments and messages from admirers. There were groups I belonged to that were based on different themes. One was about fantasies. A question was asked to the group about your deepest darkest fantasy. A few people had started to respond and I read them. I got to one a middle aged married woman had posted and her fantasy was to have sex with her son. Of course I knew this was a fantasy of some and also a reality for others. Her response was well written and seemed very sincere. You could almost feel the desire she had for him.

I surfed around for a little while and stopped by an erotic story site. I always like reading the top rated ones or some new ones. I went down the list and saw a highly rated one. It was about a woman and her son. Reading about that woman's fantasy on that other site got me curious so I opened the story. I spent the next 30 minutes or so reading it and re-reading it. She described the experience in nice detail how different sex was with her husband and her son. I shook my head and thought that sex with your son must be very special for someone to consider that move.

While I had been reading the story I hadn't noticed that I had also been playing with my pussy. My hand was under the t-shirt and I was rubbing away. I was very slick and wet and I read the good parts again and shuddered with my second orgasm of the day. After I was done I wondered if I did that because I was horny from ovulating or did I get off on the idea of having sex with my son? My eighteen year old son Dennis who was a little slow on the take up and very shy with girls and I were the only people in the house today as my daughter Marie was spending the weekend with a friend.

Now I have had lots of kinky sex in my life, some pretty wild but I will be honest I had never ever considered i****t. Sure I had seen my sons cock when he was growing up but sex between me and my son had never crossed my mind. That is up until right now. That woman who had the fantasy seemed so turned on by the idea and the woman in the story loved it so much she only wanted to have sex with her son. I had pulled my fingers from my pussy and was looking at them all covered in clear slick goo. As I was looking at them I knew my son was on his bed in the other room. I chuckled to myself thinking he probably would have no interest at all in me. Looking at my fingers again I heard his name being called. It was me who had called him and I didn't even realize it until the words was already out of my mouth.

Dennis my eighteen year old son came walking into my office a couple of moments later asking what I had called him for this time. I was sure he was expecting me to tell him off for something or ask him to do something for me which in a way I had been thinking just that. I asked him to sit on the other chair in the room just inside the door and he did so. I was really nervous and I hadn't even done anything yet. I knew he read a lot of sex stories on his computer and also visited quite a few sites on it to but what I asked myself now was would he really want to do something with his mom? Maybe I would see if he would lick my fingers. I mean if he wasn't interested in that then he probably wouldn't want anything beyond that.

I said what the hell to myself and I dipped my fingers back in my wet pussy while my back and my chair were still facing away from him. I was sure he could smell my wet pussy from where he sat. Doing this was exciting and not only was I so nervous about maybe getting caught by my daughter or my ex but also it being so very wrong and he may even be disgusted with me and tell someone about what I wanted him to do then I would be in very serious trouble.

I told myself it was now or never and asked him to come around my chair and check something out. He cocked his head to the side wondering what it was I was talking about with him being a little slow on the uptake but he came around to see for him-self. I don't think he quite knew what he was supposed to do. He froze for a moment then slowly looked up to my face. Well he was a little curious at least and hadn't run away screaming. I nervously stuck my fingers under his nose and watched his nostrils sniff my fingers. Again he looked up at my face and this time his eyes were as wide as saucers as he realised what he was sniffing. Then he sniffed them again his nose getting closer to my wet fingers this time and I saw and actually felt him sniff them this time and as he sniffed his tongue snaked out and he licked my fingers.

I watched as his tongue went back in his mouth and I knew he was enjoying tasting me. He took a second, third and fourth helping from my fingers and I guess he liked my taste as he was now grinning from ear to ear. I dipped my hand under my t-shirt and into my wet pussy a few more times and again he would lick my juices off my fingers. OK, where was this going I hear you ask? Doing this was exciting but I knew the next step was to see if he wanted to lick directly from the source, my pussy. The only thing I was nervous about at this point was getting caught. I knew that was unlikely with only the two of us in the house but I got up and check all the doors to make sure they were locked.

When I sat back down in my big office chair I pulled up the t-shirt I was wearing. I was naked from the waist down now. I sat at the edge of the chair so that my pussy was easy to get to. He stood there with his tongue hanging out and with a very big bulge in his pants as he looked at my bare pussy for the first time. I leaned back in the chair positioning my open and exposed pussy very close to the edge of my chair. I was breathing hard and shaking a little waiting to see what he would do. He sniffed the air smelling my arousal and now had a lustful look in his eyes as his cock tried to rip threw his shorts.

This was new for him and he hesitated. Then frozen I watched as he got down on his knees and his tongue came out again and he licked me from asshole to clit. OMG it felt so good. I leaned back and closed my eyes hoping he would keep going and that's just what he did. Once he found the source it was like he couldn't get enough. His tongue was now lapping at me now using very long stokes which no man had ever done before and it didn't take long for me to shuddered with another orgasm.

The more fluid I produced the more he continued to lick my pussy. I felt another orgasm wash over me and I jerked a little as my clit was super sensitive now almost too sensitive to touch. The way I was leaning back in my chair his face was visible between my two large breasts. My nipples needed attention while my pussy recovered enough for him to do that to me again. I knew if my breasts were leaking milk he would be licking them all day. Maybe one day if he gave me a baby he would get to try that to. My nipples were rock hard and very long now with the thought of my son actually feeding from my boobs. I reached down and got some of my pussy juice and rubbed it on my nipples which he then licked and sucked on repeatedly from one to the other. His tongue was sending shock waves through me.

I pulled Dennis up by the ears and as we kissed long, deep and passionately I felt something against my thigh. Something that was hard and pointy was poking me mainly on my inner thigh but once or twice on my pussy lips too. I scooted in my chair a little to try to get my nipple in his mouth again hoping he might even nibble on it. I guess that little shift of position was enough to cause what happened next. I felt the hot hard pokey thing hit right in the opening of my pussy which was spread eagled in the chair and very wet.

As soon as it did my son scooted forward and thrust his hips. Right then about five inches of his cock went inside my pussy. Immediately he started thrusting trying to get more in. I was in a state of shock. Time froze for a moment for me. I had not made the decision to have sexual intercourse with my son just yet but it was happening right now. Did I want this? Was I ready? Did I need to think about this?

I panicked and pushed myself up off the chair and stood up. I didn't want him to think he did anything bad so I just kept telling him it's "OK". I paced around the room for a moment. His cock had been inside me. I actually had been having sex with my son even if it was only for a few seconds. I was freaking out now wishing for someone to help me get past this point and decide what to do next. I looked at him and he was laying there on the floor next to my chair. He looked at me and he was smiling. He didn't care about social ramifications at that moment all he wanted was a tight hot pussy to shove his cock into. I laughed at myself and decided this was just sex. It was supposed to be fun and enjoyable. It didn't matter who was involved.

I decided to try it again. I peeled off my t-shirt and threw it in the corner. I wanted to be as naked as Dennis now was. I guessed the best position to have sex with him would be in the doggie position so I got down on my hands and knees. My large breasts were hanging down under me. Their weight was pulling them down. The brown wrinkly ends and long nipples were pointing straight down. I always loved this position because it made them swing. I needed him to get re-interested in my body so I held a boob out to him. He crawled over to me and licked it then he went around my body almost like he was examining it while giving me little kisses and licks. When he got to my backside and started to lick my pussy again it was nice but that's not what I wanted him to do. I wanted his large cock in my pussy and I wanted him to fuck me silly. He was close enough to me that I could reach back and grab his cock and gently pull him to my pussy.

Once there he shuffled forward and started to thrust his hips at me. I looked between my legs and saw that his cock was hard and about at least eight inches long and his balls were the size of plums. I reached back and gently guided him to the entrance of my pussy. This was so crazy but I wanted this so badly. There would be no problem with lubrication as my pussy was still dripping with my juices. I managed to actually get the tip to touch my entrance before he pushed forward and his cock was back inside me.

Most guys start slow and try to last a long time. They stroke slowly at first enjoying the feeling and try to hold back. Only at the end do they stroke quickly as they cum. My son however began jack-hammering me right from the beginning. He was absolutely hammering my pussy. It was just rapid fire strokes. His cock was a good and my tight pussy was gripping it but he was getting more and more inside me. I looked down at my boobs and they were flopping all around from the hammering he was giving me. His cock felt so good inside me and this was an amazing fuck and I just tried to relax and enjoy it.

I was on my elbows and knees and I was actually pushing back into his thrusts. He was trying to get all of his cock inside me. I was already pretty full of his cock. He kept pressing it in and I let him. The tip of his cock was pressing right into my cervix now He was so deep inside me and I felt a warmth there. His cock was now throbbing and he was cumming deep inside my pussy. My son was actually cumming inside me. My pussy was gripping my sons cock and he was still throbbing inside me and I had no idea how much cum he was depositing there.

I was able to look at a clock and figured that we had been fucking for about 15 minutes when I finally felt him pull out with a plop. When he was out of me I just laid down on the carpet in my office. I had just had sex with my son for the first time and I was full of his cum and he had made my pussy his. I laid there for a little while then struggled to my feet as I was actually sore all over. He had given my pussy a real pounding. I looked at my carpet and saw the mess that we had made and I would have to clean that and of course use a towel or something next time. Was there going to be a next time?

I went back to my bathroom to clean up. I ran the bath instead of the shower. Climbing in the warm sudsy water I relaxed. I leaned back and closed my eyes. As I lay there I rubbed my lower tummy. I knew his sperm was in there. I was ovulating so I knew there was a good chance my egg was there too. Logic told me that his sperm was bouncing off my egg trying to get in. The fact was I knew that was actually happening and that nature would probably let one of his sperm penetrate my egg and make me pregnant with his baby.

I had already made the decision that we would do this again. I was not sure when but if I was not pregnant this time I wanted his cock in me again the next time I ovulated and I wanted him to give me a baby.
