She's my step-sister

Well, truth be told, she's just my step-sister. My dad remarried when I was 10, and Alice has been with us ever since. We had both always wanted a sister, so we fell into together from the very beginning and became best friends. My step-mom, however, is another story.

Even though we weren't blood-related, I really considered her to be my true sister. I loved her like family.

Anyway, Alice is coming over tonight, so I guess I have to put my plans on hold for that. I promised her we'd have a movie night, and eat kettlecorn like we used to do when we were younger. Ugh, there was so much else I could be doing. I was still painfully horny.

You know, Alice's body was pretty nice. She's not very "developed", but she's sexy in an innocent, petite kind of way. And now that I think about it, taking baths with her when I was younger always did feel kind of funny. When we'd get shopping or get changed together, my eyes always did linger a little longer than it should. Maybe it was my month long dry streak, but I was convinced that my little sister was responsible for my lesbian awakening.

But she's my sister? Isn't that wrong? Well, she's my sister and my closest friend. I know her best, so who else would she take as a lover? The only problem was that I knew her streak of boyfriends, and knew she was very straight.

I grinned devilishly. All I had to do was seduce my little sister. My loins ached in response to the thought. I needed to formulate the plan, but before I could do much thinking, the doorbell rang.

I ran to the door and opened it. Alice was waiting for me with a big grin on her face. "Christy!"

"Alice!" I called back, and we embraced.
