Trading my wife for her sister

This is a story of how I traded my wife for her little 19th Arnold sister

My wife is a very attractive girl. Her names Kathleen , we’ve been married since she was 18, and I was 42. She’s 23 now , 5’2”, 107lbs, she’s a little skinny with a flat stomach, nice breast and a nice set of buns, she’s a ginger with shoulder length hair. Our sex life is great, we fuck at least 3 times a week. But the apple of my eye has always been her sister Sarah. Hey sister is really tiny at 4’11” and if I remember correctly she weighed 93lbs. We would always flirt with each other playfully even when I started dating her sister.

She’s very petite, nice small boobs and a nice perky ass for a girl her size, her legs are slim and sculpted. She’s also a ginger with shoulder length hair. For her 19 birthday party I gave her a necklace and a new iPhone. She was extremely happy about the iPhone that she have a hug and s lingered kiss on my cheeks. She was wearing a tight fitting short white dress and an orange thong that was clearly visible to the back and no bra since she was home with her mom, dad and me and Kathleen . She looked like a little sexy high school girl in her outfit that I couldn’t help myself that when she hugged me I dropped my hands and cupped her ass cheeks when I thought no one was paying attention, but my wife was.

On our drive back home. My wife told me she saw what I did. She wasn’t mad, she was always really cool, we were very open with our sexuality. In the past we joked about having a threesome, so I jokingly told her I would call a buddy over and we can both share her for a night if she’d let me have her sister. She got extremely excited and told me that Sarah always had the hots for me. That started when we were dating and we’d sometimes come back to her place when her parents wasn’t around to fuck, on that particular day, sarah had come home early from classes and peeked in the door when she heard us fucking.

So we made a deal, she would talk to Sarah and I would get a buddy of mines. A couple days passed and my wife told me that Sarah had agreed to our little deal on one occasion, she wanted the “boyfriend experience” my wife blurted out chuckling, but I thought it was adorable. The weekend came and we got things in place, my wife was expecting my buddy Kevin to show up that afternoon, but me and Sarah chatted over the phone and had arranged for a weekend at a beach house. Since I would be gone a couple days and wanted to save myself for her, I got my wife a bit of surprise.

When after noon came I gave her a small gift bag I’ve been hiding from her. She gleamed with excitement when I handed it to her, she likes nice thing and I love buying them for her to see her smile. She went in to change and about 15mins later called me into the bedroom door. She was standing in a white lace g string and bra set. My cock instantly got hard looking at her, same time I heard a car pulled into the driveway and my phone rang.

I told her to sit on the bed. A few minutes later, I walked in the room to find her sitting exactly where I told her too, her eyes opened wide and her mouth hung open as if to say something but she stayed quiet. Beside me was my two nephews. One 18 and the other 19, my sisters kids. Being young virgin guys they were both shaking and scared to death. They we’re really good boys, smart, but nerdy, small and skinny. Took after my sister and her husband.

“Hi aunt Kathy” the older one said and the younger one followed his big brothers lead and said hello. She instantly got up and hugged them in a older sister kind of way that she always does, to be honest she pitty them, we both did, Kathleen just looked at me and winked and I returned it. Nothing needed to be said to each other.

“Sit everyone, let’s have a talk” with that the boys sit first and she sat in the middle of them. “Remember guys, this cannot leave this room, as far as your parents know you are just spending the weekend. From the look on Kathy face she was horny as hell, he eyes were puffy and she was sweating a little above her upper lip. I reached for her hand and she got off the bed leaving a wet spot from her pussy where she was sitting.

I grabbed her ass and lifted her up and she wrapped her legs around me I sucked her tongue hard and deep. If I leave her standing she too short that I have to scrunch over to reach her lips so it’s almost second nature for her to jump up and straddle me. The boys looked on as we made out. I don’t know how these boys were gonna deal with her, Kathy was always a nice charming girl, but when she’s horny she’s a sex crazy maniac. Now I’m a big guy with a big cock and I have fucked her rough so many times that her pussy has been stretched, still very tight for me.

But for these boys and their small dicks, will pose a challenge, but I not worried as I know my wife has a thing for young skinny boys. A lot of women and girls out here are not to fond of big dicks, we think that’s what they want because of stereotypes and porn but the reality is very different. I broke the kiss and told her “if another man was gonna have her pussy it might as well be my nephews” , “thank you for this so much”

Stay tuned for part two.
