Chapter 1

When I was having cybersex with CrossEyedMary69, I never knew the one important detail - that she was my sister.

I'm sure things would not have turned out the way they did, if I knew who she was, but it was a situation where my ignorance made my life more interesting. I'm 17, and my sister, Karen, is 15 years old. Our relationship used to be non-eventful. We'd have a few arguments, and I liked her enough as a sister, but aside from that, I didn't really talk to or notice her that much. She had her life, and I had mine. Also, more importantly, we both had our own computers.

This story isn't my English paper, nor am I submitting it to be published in any important journal, so I'm going to ignore all the little details and everything. Should I describe myself? Should I describe my sister? Let's forget that. It's not that important anyway. Just pretend she looks like someone you know. Maybe your cousin, your daughter, or better yet, your sister.

Anyway, I used to visit chat rooms to meet people from my city. When I say people, I really mean "young girls". And when I say "meet", I really just meet opportunities for online or offline sex. CrossEyeMary69 started off as just another young girl that I would chat with every time I was bored. I remember asking for her picture, but she wouldn't send them to me, telling me she had none on her computer. When she asked for mine, I would give similar response, although I did have a webcam. I just didn't feel too comfortable sending out my pictures to random people. I always figured that those could come at a later time.

I'm not going to lie and pretend that our chats were great, and that we loved chatting with each other. We really didn't have that much in common, and I didn't get online looking for her.

At first, at least.

Eventually, the chats slowly started moving towards a topic which both of us enjoyed talking about. And that was sex. We started talking about our views on it, and it moved towards our (very little) experiences, and slowly towards our fantasies. That's when we saw how much we had in common.

At first, I didn't want to tell her about my fantasies of incest. So, when we were talking about our fantasies, I wouldn't divulge all my dreams. So I'd sit in my room, and I'd tell her how I wanted to have sex with a girl in public, against a wall, on a table, finger her in a restaurant, and she seemed to have similar desires. And as these conversations would continue, I'd take out my cock, and play with myself, as she described her fantasies and her wishes.

Initially, I wouldn't tell her what I was doing when I was talking to her, but I'm sure she knew. I was almost certain she was doing the same thing. And the more I talked, the more we were open with each other. When I finally told her of my fantasies of incest, and she responded that she enjoyed the idea of having sex with her cousin, father, or brother, I seemed to shiver with arousal. I told her that what she said was so sexy that I had to masturbate to it, and she told me that she was doing the same.

After that, we rarely had a conversation that didn't involve us talking to each other about what we would like to do to each other or others, and each of them with end with us masturbating.

And all the while, she was Karen, my sister, sitting in the next room.

Can you picture that? She was there in her room, her panties pushed aside, her fingers touching her wet pussy, while chatting with me, neither of us aware of the coincidence. And me walking past her 3 minutes after our chat ended, and neither of us even guessing what had just happened.

I don't think our cyberchats would interest anyone besides ourselves, but I'd like to show you an example, before continuing with telling with about what happened next.
