Just too hooked
I have an older sister, and we've been sexually involved with each other for a couple of years now. She's way older than me, but it doesn't matter, actually I feel it's part of the charm and what made our attraction possible in the first place. I'm 24, she's 37. Instead of just a sibling, I always saw her as a woman, she was turning into one while I was learning to walk. And she was always attractive... I confess here, as I confessed to her, that my first masturbation ever was thinking of her. I was always attracted to big boobs, and she's definitely not lacking in that department.
I was also drawn to how free she was. Our mother tried her best to raise her into a "decent woman", but today they're not even in speaking terms since my sister became "a whore". My sister also calls herself that, but in an ironic sense: to her, a "whore" is someone who embraces her sexuality fully and isn't afraid to explore and enjoy it to it's full potential. She always spoke about sex freely, so my teenage hormones went on overdrive anytime I was near her.
She's the kind of woman that hasn't been married or had any children, and she intends to keep it that way. So despite being well into her thirties, she enjoys life more than some younger women do, so she's often at bars or throwing parties. It was at one of those, at her place, that I got drunk, so she told me I could crash there. I was helping her clean up after everyone was gone that I kissed her... and she kissed me back. When I realized what I was doing I tried to pull away, but she asked me to continue. "It's ok, I wanna do it", she said. "don't think".
I can't describe how much we both enjoyed that night, not only because it was possibly one of the best sex experiences either of us had had, it was different, intense and addictive. We pulled an all-nighter, and we kept meeting up after that... every time more frequently. I couldn't explain it better than she did one day when she told me "maybe that's why incest is a sin. it's too fucking good".
We often date a few different people to keep apperances, but since then we've been pretty much exclusive to each other (except when we engage in group sex or swinging, instances in which we present ourselves as an ordinary couple), and in secret (with the exception of one friend of hers who is ok with it).
And to be honest, we're just too hooked on each other to think on stopping, and my sex life has been a bomb with her. I love how experienced, shameless and dirty she is. Sometimes her words mid-sex are enough to make me cum ("breed your whore sister" can trigger me into cumming inside her in seconds. she's on the pill btw). We play dirty games elsewhere, like me introducing her as my whore if we meet strangers, or talking on the phone in public like any other couple talking about sex. We've traveled together to far away places so we can act like any other couple, where no one knows who we are so she can be loud in our hotel room and say she wants her brother to fuck her good.
Maybe some people will find it gross. Others will tell me I should be out there fucking other girls. I don't care, she's the only woman I'll ever need.
