As Thanksgiving approached, it was decided that I would stay with my sister and bil at their house and my parents would have my grandparents and my mom’s sister and her husband and 5 teenage boys at their house. I was glad to escape the testosterone hell that was coming to my parents house for the relative quiet of my sister’s house even with my one year old niece. It Besides, I have always gotten along with her husband Brian. We’ve always been kinda flirty with each other but never took things any further because he really does love my sister.

The first couple if nights found him and I taking shots as the three of us hung out. Him and I doing some shots while my sister just watched since she was nursing. On Wednesday, I told them I was heading out to hang with some friends but that I would be back around midnight. Brian looked at the dress I was wearing and said he’d be surprised if I was back before noon tomorrow. I flipped him off and left.

I met up with a bunch of people at a bar in town and around 11:30 most of my best friends from high school were leaving. The wait times for an uber home were crazy so I called Brian and asked if he could come pick up me and another girl and take us home. He said okay but I definitely owed him and he came and got us. After dropping her off he asked me what I planned to do to pay off my debt as I felt his hand on my thigh. I slid my dress up my thigh and asked asked if my sister was awake, he Said no and I reached over and grabbed his dick through his jeans. At the stop sign he undid his pants and I pulled it out as he pushed my mouth down onto it. When we got back he told me to keep going until I was a good girl and swallowed his cum. It wasn’t much longer that he filled my mouth and then we went in the house. Once he closed the door to the garage he pulled me to him and we kissed passionately. That night we went to my bed that was on the other side of the house from where my sister slept oblivious that her loving husband and her innocent sister were fucking each other like crazed animals. The look on his face as he buried his dick in me. We fucked until he flooded my pussy with two loads of cum. Once we were done he kissed me again and he went back to my sister.

I stayed with them through the weekend and Brian and I fucked at least once every day and have plans for me to spend more time in my bed over Christmas.
