I was adopted young by a family that were nudists. My three older step sisters came home from college for a major holiday. I was adopted because my step dad had too low a sperm count and they wanted a son. Now I've graduated hs and got summer job. With my sisters away at school and dad losing interest in sex, I was now the man of the house. My mom was the first of many females I knocked up. Over the holiday I got finally have sex with my 3 step sisters. I love family fun.
