Nancy got married when I was about 10 years old. She had been my babysitter whenever my mom was at work. Like any sister, I'm sure she resented having to take care of a younger brother. I suppose that accounts for the many times she would tease & torment me. Nancy and I were very close, and I would often call her my "second Mommy."
When I was a teen, I would often spend weekends with her and her husband. Roger and I would occasionally argue about silly things. I didn't understand then that I was probably jealous of him. But, I loved to visit my sister. She treated me like an adult and valued my opinions about everything. Roger worked odd hours, and I'm sure she appreciated the company.
At 18, I was very sexually frustrated. I had not yet been with a girl and would find release in masturbating to my Dad's playboy magazines. I knew right where to find them. And when I visited my sister, I also knew where Roger hid his magazines as well.
Roger's porn was much more hardcore than my Dad's Playboys. There were open leg pussy shots, couples fucking, cock sucking, lesbian cunt licking, even a book about incestuous relationships.
I would "borrow" the magazines, go off on my own and jerk off until I shot cum all over the room. But whatever pictures I looked at, my fantasies usually came back to my sister. I would fantasize about seeing her breasts and pussy. I thought about licking her pussy and having her suck my dick.
I was far too cautious to try to peek in at her while she was changing, but I thought about it time and time again. Sometimes I would imagine going swimming with her in her pool. In my thoughts her bathing suit top would accidently would come off, and I would see her full, beautiful breasts. I wanted it to happen so very much, but it never did.
I was totally shocked the day she caught me trying to return Roger's magazines to their hiding place!
Nancy wasn't shocked at all. She was a little upset that I was intruding on her and Roger's privacy. She told me that if I wanted to jerk off, I should just ask to borrow the books and she'd get them for me. My cock got a little hard when I heard my sister say the words "jerk off."
