My GF Tasted Her Sister On My Cock [MF]

This is the story of how my girlfriend ended up tasting her own sister on my cock. My girlfriend’s name was Alison we had met during our last year of high school when we were both eighteen. About 3 months into our relationship Alison still didn’t want to have sex, and I was getting frustrated as all she was putting out were hand jobs. She wouldn’t even give me a blow job. One night while I was at a party with my older brother and his friends I ran into Alison’s older sister Rachel, who is just as hot as Alison, but with bigger boobs. “So have you and Alison fucked yet?”She asked with a chuckle. “No, not yet, but I am working on her.” I replied. “If Alison won’t do it I will,” she said. She smiled, gave me a kiss on the cheek and then walked away. I was left just standing there alone with my hard cock. I was definitely interested, but I after thinking about for a bit I had decided she was just fucking with me. Later that evening I could see Rachel was getting very drunk and I started to see other guys noticing her. Given the crowd at the party I knew it wouldn’t be a good idea to leave her there alone so I decided to take her home to keep something bad from happening to her. I told myself my motives were pure I was just looking out for my girlfriend’s sister. Nevertheless on the drive home I couldn’t resist asking her if she was serious about what she said about having sex.

I came almost instantly as I was a horny eighteen year old that was use to hand jobs. She swallowed all my cum without missing a beat. When it was done she sat back up in her seat, looked at me and said, “is that serious enough?” This quickly became a habit. Rachel and I would meet almost every weekend and suck and fuck. She was very kinky, taking it in every hole. Nothing was off limits. She was the first girl that gave me her ass. Of course, I was still dating Alison, and she had no idea about how me and her sister were carrying on. I was also still trying to get in her pants. In fact, the more I fucked Rachel, the more I wanted Alison. I wanted to see if she was just as tight and just as kinky. Eventually, Alison gave it up four months into our relationship, and she was fucking amazing. I was not her first, and slipping my cock inside her was like trying to fit a hot dog into a pencil sharpener hole. I tongue fucked her until her cunt was dripping wet with her cum and I still had a hard time pushing it in. She was loud and even squealed. She complained it hurt but told me not stop. We fucked good and hard for about 15 minutes, until I came inside of her. Once we started fucking, we could not stop. Alison loved me tongue fucking her and fingering her pussy and even her ass, but unfortunately she never let me fuck her ass. I was ...
