My Sister and her Lesbian Friends

It wasnt as if it happened all of a sudden. Its not if there weren't signs. It was if it was a out of sight out of mind thing. I followed my older sister everywhere. The strange thing was that she didn't seem to mind. I wasnt that younger and her friends thought I was cute. She didnt have that many boyfriends when we were growing up. Not that she didn't have a great body or pretty face.
         Many guys hit on her but it seemed that she would rather spend time with her little brother and her friends. During family camping trips we would sleep in the same tent and zip our sleeping bags together. I would be invited over to sleepovers with her friends. We were still young and everybody thought it was cute.
          When we were still in our teens there was a party over one of her friends house. One of her more daring friends. Just 3 or 4 girls and me. Then someone passed a few beers along and a few joints and I was sworn to secrecy. Then the games began. All the girls were in their pajamas or night gowns. I was wearing a pair of sweat pants. All the girls were developed and looked so hot with the lights dimmed.
          The game turned to truth or dare. Once a few truths began the dares came out. Sexual dares. Soon all the girls were topless and I was naked. My sister was completely nude. Then my my sister dared me to kiss one of her friends. Then one of her friends dared my sister to kiss me.  Then someone dared my sister to put my cock in her mouth. But then as I grabbed her face I wouldnt let go and my sister didnt stop sucking and soon I was halfway down her throat with her friends cheering us on and soon I had ejaculated in my sisters mouth. She sucked and swaloowed like a pro. Then my sister dared her best friend to give me her cherry. Which she did as well as another girl. I was in pussy heavan. Then I saw why these girls were such good friends. Soon they were all on each other. Kissing and eating each other pussies. As my sister came up from between one of the girls legs she smiled at me and kissed me with her face covered with pussy juice. Then I was upon like a dog in heat and I was inside of her. My third virgin. I would fuck the last a few hours later. They were all Lesbians and I was there only cock. I would continued to be my sisters only cock. The friends broke up. I got one pregnant and she moved away. I never got my sister pregnant though I can hinestly said I tried. She confessed to my parents when she came home from college that she was a lesbian. Though later that night climbed into my bed and fuck me like a red hot whore. I never asked her why she would have sex with me her brother and no one else and I didn't ask. I eventually married her best friend. Knowing and allowing that my wifes relationship with my sister continued as as long as my relationship was able to continue with my sister as well. which it did. In fact we lived in the same house for many years.
