The Last River Party

Our grandparents had a house on the river. We spent most weekends there with our grandparents, not just us but our cousins too. When we got old enough to drive we had parties with our friends. My sister, younger by three years, kept asking me to take her. The party I took her to, she brought our cousin, who was her age. At the party a guy was putting the move on her so I put her and my cousin in the bedroom.

After the party friends left I went upstairs for them, they were totally naked grinding, kissing and grabbing each other. I tried to separate them, they were naked and held onto each other, showing their tits, ass and pussy, they showed it all to me. Either I fell onto the bed or they pulled me into the bed and I was going to teach them a lesson. I ended up fucking my sister, she fought me and I had to put her under control. I was pushing 17, she was 14. Fucking her stopped everything. She started crying, our cousin comforting her, I felt like shit.

We drove home in dead silence. We waited, her period was late, it never came. We had to confess to our parents, the decision was to tell the doctor some unknown guy had gotten to during the party. Our married older sister adopted the baby.

We transitioned into adults, it was impossible not to love her, hold her, make love with her. The only person who knew we were having sex was our cousin. Our son was our favorite nephew, we spoiled him. Once we were in my early thirties the family didn't oppose my cousin and I getting married. We had children, those who knew we were cousins no longer said anything, my sister never married spending her time around us, we continued to make love, it is an open secret. When our son was 15 he was told the truth. She is very close with our son.

The river house was sold after she got pregnant. It was the last river party.
