Playing with mom

Ok, my name's Kevin and I'm 14. My mom and dad have been divorced for the best part of my life and I'm living with my mother. Well I can't quite tell when it began; I think it was going on all the time.
You see, ever since I can remember my mom has been coming late from work. Well it was only Sunday evenings she was home. We used to spend the time together, talking, playing games and all. She used to do strange things though. One particular thing she did was play with my dick. At that time I didn't understand such things so I didn't think about it. She almost often did it so it came to be quite natural to me. I used to take off my pants in the evening, and after some time she would take my dick and play with it. She used to fondle my balls and hold my dick in her hand. Sometimes she would even give it a little kiss. She didn't do it a lot though, she would play for about five minutes and then I would just go off to bed.
Well, that summer I was thirteen (it was a year and a half ago). At that time I knew a lot about sex, but well I still didn't think about mom. My dick was already quite big and hard so she played with me carefully. When I went off I'd usually masturbate until I cummed.
It was another one of those evenings. Soon I had taken off my pants and she was playing with my dick. Everything seemed usual. I had a lot of pubic hair and she liked running her fingers though it. After some time had passed I felt we were doing it too long. My dick was already quite hard. My mom felt that but she was somewhat reluctant to stop. She went on with my excitement building up. At one point mom leaned down and gave a little kiss aver my balls. I didn't know what to think. The last time she kissed was about a year ago. She went on licking my dick, holding my balls in her hand. I tried hard not to cum but she put the tip of my dick to her lips and pressed strongly on my balls.
I cummed. Moreover I cummed into her mouth and over her face. She got off and I looked at her. All around her mouth there was white slimy liquid. I felt awful. She licked the cum off and smiled. I think I was burning red as she leaned over to me and said, "There, there that was fun wasn't it."
I could just nod back. She kissed me and went to her room.
That week we didn't talk about it any more. Next Sunday I didn't know what exactly to do. I went to the living room awfully confused. Mom came as usual. She was wearing a blue shirt and a short skirt. I tried to be normal. We played a game of chess; my mom liked it a lot. When we were finished she said, "Come on Kev, take off your pants."
I didn't know what to do, but I unzipped my jeans. To my surprise she took her blouse off, she had a bra under it.
"Do you want me to do it like last time, dear?"
I didn't know what to say, so I just nodded. She smiled and got down. This time she took my dick in her hand and started licking it. She took it in her mouth and actually sucked it.
I was in a half lying position on the couch. Suddenly she stopped. I raised my head and saw that she had got off. She pulled closer and knelt over me. My dick was standing upright looking at her. She saw my glance and said, "Don't worry dear, just lie back."
With those words she moved down and my dick hid behind her skirts. In a moment I felt soft flesh with the tip of my dick. Then I felt the warmth and moisture as it went inside my mom. I let my head fall back as mom moved up and down on me. I was overwhelmed with feelings. I was fucking my mother, or to be correct my mother was fucking me. I couldn't stop enjoying it, and in a moment I let myself go, filling her with hot cum.
That night I couldn't sleep. I was thinking about what had happened just a few hours ago. Suddenly at six in the morning I felt a desperate feeling. I wanted to fuck my mother again. I guess I wanted to make sure it wasn't a dream. I thought a while, then I got up and went to my mother's room.
I opened the door and came in. She was awake, reading a book. When she noticed me she put it down and smiled. She moved over to let me sit down.
"So, how was yesterday?"
"Oh, great."
I thought a while then said, "You know, I'd really like to do it again."
I felt afraid a bit, just saying that to her but she just smiled.
"Ok, but thins time I'm going to be underneath you."
I smiled. She pulled the covers off and I saw that she was naked. Her breasts were big and fell off her sides. I looked down to see her pussy. It was covered with black hair, but the pink showed from underneath. I exposed my dick and knelt over her: the way she had knelt over me in the evening. I took hold of her thighs and slowly pushed my dick inside her. It felt beautiful, different from last night's experience. Now I felt her under me, she was all mine. In ten minutes we had finished and were lying beside each other. For me it was the best time of my life. And from that time on we fuck every free minute we get.
