Fucked my sister

“Rick, Dwayne and I are going to the beach for a few days and want to know if you and Caroline would like to ride with us” my sister Jen asked me. Jen was a couple of years older than I, and we had always been close. She had been married to Dwayne for two years. Caroline and I had been married for one year. I told her I would talk to Caroline and call her back.

Caroline thought it would be a great idea and so we packed the car Friday and took off, planning to get a hotel on the way. Everywhere we stopped, there were no vacancies, until finally we found a hotel that had one room, but it just had one bed, a king size bed. We decided that would work as Jen and Caroline were both rather petite, about 5’4, 120 pounds and Dwayne was 5’8” and 140 pounds and I was even 6’ and 170 pounds.

We all had a great dinner, talked some, then went to the room and showered and retired to bed. The sleeping arrangements were pretty simple, Dwayne, Jen, Caroline, and me. Soon we were fast asleep. But sometime during the night Caroline began to cough and got out of bed and went to sleep on the lounge chair by the window, on Dwayne’s side of the bed. Later Jen somehow ended up spooned up against me and I was hugging her as I thought Caroline had returned to bed, and began to massage her breast. My cock began to harden and I pressed it against her butt.
