There are some things in life that are not planned. They just happen! My sister Donna is 4 years older than me and we have never been real tight. We were just typical siblings with an age difference. We would fight all the time over just about anything, but as we got older we managed to become friends. My sister was a wild child; I caught her more than once having sex with her boyfriends at our parents’ house. I never said anything but she knew that I knew.
There were times, and I am sure it was my imagination, that she enjoyed teasing me by having sex while I was in the house. I can understand why my sister had so many boyfriends – she had the body of a Playboy bunny. At the age of 16, she was already a 36D with a small waist. Her waist only made her breasts look bigger than they were and her long blonde hair did not help. I was always getting ragged by my friends about how hot my sister was. I am only human and have to admit that looking at my sister’s hot body turned me on like any red blooded American boy, but I never forgot that she was my sister.
I hated that everyone found her so hot and sexy and that dating was so easy for her. I was just average looking and I had to work to get dates as I got older. The upside of that was that I learned how to treat a lady and more specifically how to please her. My sister just went from boyfriend to boyfriend never learning how to choose a good one because she never had to.
Several years later I married a beautiful woman, who I still love to death. We are a perfect couple and I am looking forward to growing old with her. Her name is Susan and she is the woman of my dreams. She is sexy, smart, loves sex, and has the most beautiful long white blonde hair you have ever seen.
Donna on the other hand has been married 3 times in 5 years always going from one good looking (but not very nice) guy to the next.
So, this is where my story starts. A month ago my sister invited me and my wife to a party she was having at her house. She has a huge house thanks to her very rich ex-husband and she wanted to throw a costume party. I had not seen my sister since her divorce and it sounded like it might be fun. My wife had a really sexy nurse outfit that I loved and I was going as a California doctor. I knew I looked dashing in my Armani Suit with a Stethoscope hanging around my neck. The black leather doctor’s bag only added to my Beverly Hills look.
It was hard for me to even get dressed watching my wife. Her costume was so low cut that it showed off her beautiful cleavage. I could not stop myself as I reached around her waist and cupped her beautiful breasts in my hands. I kissed her neck with a loving touch as she pushed her breasts into my hands and I felt a familiar stir in my pants.
“Now, Now…… cool down or we are never going to get ready,” my wife said with a purr.
“Come on baby…. Please leave the bra off,” I begged.
“If I were to do that you could see my nipples through the costume, it is so thin,” she said with that little wicked smile that always drives me crazy. “Besides what would your sister think if I went dressed like that?”
“Yeah right, you know my sister. She will be dressed to impress and you know it,” I reminded her.
“OK you win. I will take it off,” she said.
She gave in way too easily and I realized that the little minx had been waiting on me to ask her. I watched as eagerly as a hungry baby as she removed her bra. My heart skipped a beat looking at her beautiful nipples pushing against the material which was so sheer that it was really showed off her hard nipple. As she walked in front of me I could see her backlit from the bathroom door and the whole costume was almost see-through against bright light. I could see the brown of her areola around the nipple and hoped she didn’t realize just how see through it was. She knows I love to show her off, but I was not sure she would really go without a bra if she knew just how much of her would be showing.
