Let me start by prefacing this story is something I wish had happened, most are true with the exception of the sex with her those are things made up in my perverted mind. I had been dreaming having sex of my sister away at college why I didn't know although nothing happened other than me jerking off to her picture many times a week. I found jerking off thinking of her caused ejaculations like I had never had before and was embarrassed that it took me wanting my little sister to reach that kind of satisfaction.
My sister Ann is 18 months younger than me but was only a year behind me in school because of the way our birthdays landed. We have an one older brother & one older sister who are 10 years & 4 years older than me respectively. This story started in my mind the year I was 19 and she had just turned 18.
It was a summer weekend I was home from my first year of college and she had just graduated from high school, my older siblings were out living on their own and our parents were away for a long weekend.
I got up to go to my summer job at a local hamburg & hot dog stand while Ann was still sleeping, when I arrived I started work and after about an hour in there was a fire in the grill and they had to shut down for the day as it caused some damage so I left to go home.
When I got home I went upstairs to my room to get out of my work clothes and into some shorts. When I passed by her room the door was open, she must have just gotten in from taking a shower, my beautiful little sister was totally naked. I stopped and was staring at her. She was a short girl maybe 5' 1" or so with very perky tits not large by any nature but also no where near flat chested, long very light brown hair and very fine pubic hair that looked golden. I could see her vagina so clearly thru that fine pubic hair and noticed my cock was rock hard. Ann saw me after what seemed like 10 minutes but was actually maybe 1 or 2. When she saw me she yell get out you perv.
I went to my room hoping she didn't notice the tent in my pants that formed from my hard cock. When I got to my room I got undressed and started dreaming about what I just saw. I started to slowly jerk off while picturing her in my mind until I blew my load all over my stomach and then cleaned myself off. This all is the true part of my story and what comes next is something I have wished for years to have come true.
