My wife has an older half-sister who is 13 years older, she’s in her 40’s now. I never thought of her as super attractive, but she’s tall, blonde, somewhat fit, and has nice, good-sized tits, not huge but she fills out a sweater well. My wife and I have not spoken to her in over a year now, due to ongoing issues between them and my SIL’s generally shitty personality. The best way to describe her would be to call her a complete bitch.
Because of her personality I never found myself attracted to her, until one night my wife and I were fooling around. One part of my wife and I’s sex life is talking about other people we’re attracted to that we know and fantasizing about what we would do with them. One night, my wife asked me if I thought her sister was attractive. I hesitated for a moment, then I asked her if she wanted me to be completely honest and she said yes.
I then admitted to my wife that I would love to hate-fuck her sister and become completely dominating while humiliating her. She then started into a role play that had her acting as her sister and she was “seducing” me because she (my wife’s sister), wasn’t satisfied at home. I feigned tentativeness, then began degrading my “SIL” by telling her how much of a slut she was for seducing her sister’s husband. I told her how much I hated her and her “big, stupid mouth” and made sure she knew I thought she was a total cunt. My wife played along and began snapping back at my insults. The hottest thing I remember her saying was after I called her a slut for seducing me, she said, “That’s right, and here you are telling me how much you hate me, yet I can tell how bad you want to fuck your SIL right now…”
It didn’t take long before I told my “SIL” to lay down like the good slut she was and I immediately slid into her pussy and began fucking her relentlessly. My wife usually doesn’t like things too rough, but as I kept fucking her harder and harder, she seemed more and more turned on. I kept up a constant pace of furious pounding into my wife’s pussy while calling her by her sister’s name and continually calling her names.
After just a few minutes, I was almost ready to explode when my wife said one of the hottest things she’s ever said to me. She said, “I want you to admit to me how much better my pussy is than my sister’s.” After hearing that, I couldn’t hold it any longer and my dick was ready to explode. As I muttered to her, “so much fucking better”, I soon let out a huge moan (which I don’t normally do) and exploded inside my wife’s pussy with one of the best orgasms I’ve ever had. As I filled my wife’s pussy with cum meant for her sister, she let out a moan and shuttered with an orgasm as well.
We’ve only repeated this role play sparingly since then, trying not to over-use it, but whenever we do, both my wife and I are completely spent afterwards from some of the best sex we ever have.
