My name is Bill. I'm thirty-five, and I've been happily married to my wife Sherry for ten years now. Just recently, however, I've finally accepted that I'm totally in love/lust with my own sister, Erica.
This is the story of what transpired within our marriage when Erica came to stay with us over the holidays. I'm quite sure Sherry suspects something, but there's no way she has any idea just how far Sis and I have gone in the past. In any case, all of us just avoid talking about it.
It really all started years ago when Erica and I were both still teenage kids. Although she was older than me, we were very close. Erica would change clothes with her bedroom door open. Our rooms were across from each other and when our doors were open I could see straight in her room. It seemed that Sis always waited till I was in my room to do this, and it was obvious that she knew I could see her.
At her young age Erica was slim and beautiful with long, blonde, silky straight hair. Almost fully developed at the time, she looked like Heidi Klum, complete with fabulous tits and a nice round ass. She was absolutely gorgeous and so of course I looked.
Sometimes when Erica changed her clothes she would just run around her room naked for a long time. Our parents always seemed to be out shopping or something when she did this.
The thing with Sis soon transferred to the bathroom. She started having to use the bathroom when I was taking a shower or a bath. I would pull the shower curtain across but it was impossible to close it all the way. It was open just enough for Erica to look at me through the mirror while she brushed her teeth or did her hair.
It was totally obvious Erica liked looking at me naked in the shower, so eventually I started to put on a show for her while she watched. I would clean my cock and balls extra well. One morning she was topless, so I started stroking myself to the sight of her young breasts. Erica smiled her approval as I stroked my hard cock into a fistful of suds, so I went for it. I started making these grunting and moaning noises as I got close to cumming. It was fun to share this with my sister.
Things went on for about six months. Then, one day after doing her usual thing in her room, taking her clothes off and showing herself off to me, Erica walked into my room stark naked. This drove me crazy, and I jacked off after she left the room.
One time after letting me watch her undress in her room with her door wide open, Erica walked in my room again. This time I couldn't wait for her to leave; I ripped my clothes off to show her how badly my huge, raging boner needed to cum right then and there.
Erica's eye's went wide when she saw my hard cock pointing right at her naked body. "Lie down, brother, let me help you with that," she smiled. Then she sat on the side of the mattress right next to me and put her soft hand on my hard, hot tool.
I couldn't believe how beautiful my sister looked just then. I couldn't seem to take my eyes off her beautiful body; her perfectly formed breasts, the small triangle of golden fur at the juncture of her thighs, the curves of her body from her impossibly narrow waist to the roundness of her wide hips.
