This is my story re posted.

My name is Jack, I’m 6’1” and is ripped, I mean ripped, form all those hours in the gym. I use to wrestle at school, and was heavy weight champion my last two years of school. After school I went to into MMA and at the age of 20 I was MMA champ. I have blue eyes and brown hair I keep short. Anyways back to the story.

I live with my mom and sister, which is 3 years younger than me. We were close but still had our share fair of fights. My dad died short after my sister was born, so she never actually knew him, he was a pro wrestler in his days. My mother has a good paid job as a secretary for a big company or something like that. She was at times very busy, and me and my sister was home alone at most of the times. I spent my days working out, training for the next MMA tournament, to qualify for UFC. My sister was still in school. She was a hot babe, I mean hot, with long tanned legs, blue eyes, long hair which goes all the way to her fine ass with her 32D boobs.

Being a hunk I had many girlfriends at school, but they all wanted the same thing, sex! I know this may sound crazy, but I was still a virgin, I never went into second base with a girl, I wanted to have someone special I could have sex with, not some cheap girl. But saying this I did masturbate, a lot actually, I would jack off at least once a day.
I never actually thought of my sister in a sexual way until it happened. Mom had to go on an business trip with her boss, and had to leave me and my sister alone for a week or so. That was no problem for us, we both could look after ourselves. I went to the gym and returned about two hours later. I saw that my sister Michelle was home form school. She was wearing a short skirt and a white shirt. She was laying on the couch. I greeted her and went to have a quick shower. After I had my shower I went to the kitchen. I asked Michelle if she wanted a sandwich or something. She came to the kitchen and I couldn’t help but stare at her long smooth tanned legs. Her shirt was loose at the top and I could see her black bra she was wearing. I came back reality when she asked me to put mustard on her sandwich. We ate and I asked her how her day was. It was a Friday. She told me that it had been a long week and her day was actually great because she was invited to a party which the boy she likes asked her to come to. She asked me if she could go and I said okay but I will take her and go and fetch her at 10 sharp. She gave me a hug and a kiss on the cheek. She went to her room and as she walked I saw her panties and her ass cheeks. I was getting hard and knew it was wrong, but couldn’t help it.

I went for a swim and about 10mins later Michelle came out wearing a two peace bikini. she went to a beach chair and rubbed some lotion on her. “Need to catch up on my tan she” told me when she saw me staring. I just smiled and went on swimming. After an hour I climbed out and went in the house. I heard Michelle went to her room also. By this time I was hard, I couldn’t get my sister out of my head.
