My Sister Natalie

My name is mike and this is a true story that happened to me two years ago when I was 14. First let me tell you about me and my sister Natalie. I was an average kid, not much to talk about. At the time I was 5′ 7″ tall, and skinny, but i still considered myself somewhat fit as I played a lot of sports and was in good shape. My sister Natalie was anything but average. It is Ironic that her name is Natalie because everyone says that she looks exactly like Natalie Portman. At the time I was obsessed with Natalie Portman, and she occupied my fantasies more than anyone else. Naturally this eventually evolved into fantasies about my sister, and I found myself masturbating to thoughts of her at least three times a day. But, back to my sister. She is two years older than me, making her sixteen at the time. She really did look like Natalie Portman. From the beautiful, classic face, to the small perky breasts. Her skin was flawless, and she had a perfectly flat and toned stomach, and the tightest ass you could imagine. Her legs were amazing, and she was always showing them off with short shorts and skirts, even walking around the house in her underwear. Following her legs down to her feet didn’t disappoint anyone, she had the cutest toes I have ever seen and I dont even have a thing for feet.
Our sexual relationship started one day when I was getting out of the shower. Natalie burst in muttering something about moisturizer, and saw me naked as I was towelling off. She quickly averted her eyes and apologized as she left the bathroom. After I had dried off I threw on some sweat pants, not worrying about a shirt, and went into her room.
“Natalie how many times have I told you to just wait until I get out of the shower to get your stupid shit.” I realized I was being harsh and added, “What If I was jerking off or something.”
She replied “Well that’s not going to happen any time soon.” Making me wonder what she meant by that. I asked her “What exactly does that mean?”
“You havent gone through puberty yet, or your just starting it so obviously your thing can’t get hard.” I burst out laughing and asked her what the hell she was talking about.
“Everyone knows boys can’t have sex until after they have gone through puberty.” I didnt know whether she was stupid, or just that sheltered. But I quickly added, “First of all guys go into puberty around twelve or thirteen, second of all you have your facts mixed up.”
“Guys can get a boner their whole life, they just cant cum until puberty, which I have already had so I can cum.” as I said this I soon became more concious of the fact that I was standing half naked in my sisters room talking about sex.
