My step mom turned me into a sissy slut for dad

When I was in High school I would spend the summers with my dad and step mom. She was so hot and always dressed sexy, They were always very playful about sex, not like my mom and step dad. I loved the atmosphere.
During the week they would work all day and I would have the place to myself. I would always go into their room and see what I could get into. I found some picture of the 2 of them nude. Well after that I was always in their room jacking off to the pictures of my step mother naked. Little by little I would find other thing to help with my fantasies. I got into her dressed and would rub myself with her panties. It didn't take long before I was wearing her bras and panties while I jacked off. This became very routine for me every summer when I would stay with my dad and Georgia. (my step mom)

I graduated high school, did some collage and thought I would join the work f***e. There was no work in our town, so I ask my dad and Georgia if I could come stay with them in Arizona while I looked for work. They said sure and I could stay as long as I wanted. Well, things went kind of smooth for a week or two. I was busy everyday putting in application and just driving around looking for work. We would all have dinner together in the evenings and just set around have some beers and chat. I was older now and a little wiser to the way thing were, so it didn't take me to long to figure out that my dad and Georgia were swingers. This turned me on to think of her fucking other men.

As time passed and I was having no luck in the job market, I found myself at home more during the day. I was remembering back from when I was younger dressing up in Georgia's sexy undies and playing with myself. I went into their bed room and again dug out some of her things. It wasn't long before I was dressed and on the bed jacking off. I had found some more pictures of them and this time there were some shots of them having sex. With each other and other people. they were into some pretty kinky things.
