My dick had been as hard as a brick during the trip home. I was going home for my Christmas vacation from college. I was in my final year in college and I was looking forward to spending some time at home, but for the wrong reasons.
I was 22-year-old senior in college with a herd of tight, young, and horny women coming in and out of bachelor apartment 24 hours a day and 7 days a week. How could I possibly get such a hard-on thinking about returning home for my vacation? Only one reason: my sweet young and innocent 18-year-old sister, Brenda.
Brenda was in her last year of high school, but I had my eye on her since she was 15 years old. I never did anything to her back then, but I immediately took notice hot body when she started turning into a voluptuous young girl that any breathing man would beg for. At fifteen she was tall and slim, but I could tell her butt had been growing into the juicy ass it is today. Her breast were around a small C-cup size, but the sexy tight tops she wore would push them up where I could get a good look at them. Her beautiful shiny brunette hair reached just below her shoulders and her pretty faced featured a set of gorgeous pouting lips that you wanted to kiss for an hour.
Brenda knew she was growing too, so she started dressing real sexy at a young age to get enough attention from the boys at school or any older man she ran into. She liked to wear these tight black shorts that would hug her ass-cheeks so perfectly. I used hurt inside when I saw her wear those. One day I was so happy to find out she was now wearing g-string underwear. She was being careless around the house wearing some loose sweat pants and I noticed her green g-string wrapped around her petite hips. I don't know how I was able to keep myself from sliding my hand down there.
So how could be so horny for this hot girl and not do anything? First of all, she was my little sister and I wasn't able to get over the incest thing. Second of all, she was still very innocent at 15 and however slutty she dressed she didn't date that much and only had one serious boyfriend that I can image her giving her virginity to. She had stopped seeing right before her senior year in high school. And finally, I would stroke my dick and satisfy myself with the images I grabbed of her throughout the day. I jacked-off a lot.
On my way home for Christmas vacation, I started thinking about her again. I had seen a few months before, but she was sex vixen now. She had filled out the tight hot ass and her titts had grown to a juicy and firm D-cup. She is now a 5'7 sex bomb. I loved staring at her tits when she wasn't looking. She was dressing sexier than ever with short tight skirts and even tighter blouses and tops. Even in pants, you wanted rub your hands all over her body.
But I was getting laid all the time, why was I so horny for someone I shouldn't be thinking about? For that same reason. I wanted to make my fantasy come true. I wanted to hear her moan in my ear, "fuck me big brother, fuck me," while I was slamming my hard dick into her wet pussy. I wanted to fill my little sister with my hot cum. I couldn't get it out of my head, but I never thought I would actually do something. When I finally arrived home, she was first person that greeted me. That surprised me, since we were brother and sister, but we weren't that close.
She was wearing some tight jeans and tight top that plunged down her chest showing me her great cleavage. She hugged me and gripped herself on body. When she released herself, she slid down me rubbing her breast down my chest. I wanted jack-off right then and there. She didn't notice my glances and she retreated before everyone else came up to greet me.
I would tell you how the rest of day went, but it was pretty uneventful. That night I stayed up late stroking my dick with images of my slutty sister dancing through my mind. The next day I woke-up at round 12 noon and the house was empty. I guess everyone had just left shopping. I jumped in the shower and got dressed in some sweat pants and a t-shirt.
As I was walking towards the kitchen I heard something Brenda's room. I thought she had left with everyone else shopping. I peaked in her room and saw my little sister laying on her belly spread out on her bed. She was wearing tight white t-shirt that stopped just below her tits. She was wearing a pair of pink g-string bikini underwear that wrapped around her hips high. I was in heaven watching her write in a notebook while listening to music. I was about to start reaching down for my dick to jack-off, when she turned around and caught me watching her.
