I get a lot of questions about how it got started with me and my sis, so I thought I'd rather share it here ^^

First a little back story on me and how I got to be here :) 

About 3 years ago, the family got internet for the first time. I went to various chat sites and as soon as I entered with a nickname like "j15" (j is a short for "jente" which is the Norwegian word for "girl", btw) I was almost immediately flooded with chat requests from horny guys.

At first I just ignored those guys, but eventually curiosity got the better of me and I tried responding. Some of them were turned off by my lack of good writing (as if a real 15 year old girl would know everything about cybering >_>) and some of them were just worse than me at it.

One day, I got a chat request from a girl who asked me if I was bi. I said no, she asked me why etc. Eventually she linked me to a lesbian porn movie.
That was the first porn movie I had ever watched, and it really turned me on.
Ever since that day I got more and more bored of guys trying to cyber and eventually had to use a nick that indicated I was a lesbian in order to get them to stop talking to me.

A month or so later I ran across a girl who, after some reassuring that I was open minded, told me about her adventures with her sister. I don't think I had ever orgasmed as hard as I did when she was done telling her story.

Needless to say, after that I started thinking of my sis, who's 2 years younger than me. I took every opportunity seeing her coming out of the shower, getting dressed, wearing skimpy outfits etc, but still only had the fantasy.

One day I was walking into her room without knocking and I found her fumbling to cover herself up and close the video she was watching. I managed to get over there and stop her from closing it, and amazingly it was a lesbian movie. She told me she'd seen the browsing history on my computer and also noticed the way I acted with the female friends I brought home, and it had gotten her curious. 

I told her if she didn't want me to tell our parents, she'd have to do to me what they were doing in that video, and thankfully she didn't freak out.

Ever since that day, not only did I never feel attraction for a guy but I also gained a new playmate ;)
I'll talk more about what we've been doing these past 3 years in a future blog ^^
