[MF] I took my girlfriend’s sister’s virginity

I [19M] knew my girlfriend’s sister well and we are in each other’s social circle too. The other day, my girlfriend and I fought over something and didn’t talk for almost 2 weeks and her sister called me over to her private birthday party. I was held up with my college assignments but made time anyway hoping to resolve issues between my girlfriend’s and I. When I went there, her little sister invited me and informed that her sister won’t be making it to the party. I was worried but decided to loosen up a bit. After a few rounds of vodka, I was feeling trippy and decided to leave but her sister asked me to stay. I’m a terrible dancer but managed to pull some moves for the sake of it and my girlfriend’s sister started grinding against me. Now, I’ve never been sexually attracted to her but her ass grinding against me resulted in a huge boner. I bet she felt my erection and instead of stopping, she decided to enjoy it. I initially felt bad but the alcohol had already taken over and the music was intoxicating. In a few minutes, my hands were all over her and we started smooching. We headed towards an empty restroom stall and started making out. The music was playing in the background and her breathe against me turned me on all the more. She grabbed my crotch and slightly pressed them which resulted in a burning desire. When we both were semi naked and about to begin, she said “Slowly, I’m a virgin”. Now, I felt mixed emotions of cheating on my girlfriend, fucking her virgin sister but I was way too horny to let guilt stop me and inserted my erect cock inside her tight pussy anyway. “Oww” she whined which soon changed to gentle moans. To my surprise, in not time, she got worked up and started pushing against me in rhythm. We were high, our bodies were sweating a lot and were horny as hell while we fucked hard for around 20 mins or so.
My girlfriend doesn’t know about this and we still hookup from time to time. Maybe we will get caught or maybe we won’t but I’m totally enjoying what I’m having right now.

PS – My girlfriend and I were 19 years old and her younger sister just turned 18 during this incident.

Though I’m just 19, I’ve had several sexual encounters over the years and would love to share them here in the coming days.
