During my senior year at college, I transferred to a school only an hour away from home. I lived on campus but would come home on some weekends. Especially when I needed to do laundry or wanted to steal some food from my parents. My eighteen year old sister was beginning to give my parents all kinds of trouble. I had to admit I wasn't shocked. She is 5 feet 7 inches tall, has a great athletic figure to go with really nice tits. I have to admit I have jerked off thinking about my sister many times.
My parents called to tell me that they were going out of town for the upcoming weekend. They pleaded with me to please come home so that I could keep an eye on my sister. They were scared she would try to throw a party while they were away. I reluctantly agreed to come home and baby sit my sister.
Around Thursday I got a call from my sister, she was totally annoyed that I was coming home for the weekend. I could tell in her voice that she had thought she would have the run of the house. I told her tough luck. I was coming home and I didn't want to deal with any of her shit. She said fine and hung up.
Friday came around and I left for my parents house after my last class. I arrived home around 6 pm. My parents were already gone and my sister was out. She had left a note saying she was going to a party and would be home late. I threw in some laundry and put on the TV. After a few hours of flipping through the channels, I was getting bored. I was also getting horny.
I went upstairs to my sisters room to see if she had any porn. I checked her room, lifting the mattress, in the closet and in her drawers. No porn. I didn't think she would have any but I was getting desperate. I was about to leave when I noticed her laptop computer and a bunch of disc's next to it. I loaded up her computer and tried the first few disc's, nothing of any interest. When I got to the last disc in the pile I didn't expect much but threw it in anyway. Wow was I shocked!
On this disc, I was watching a homemade movie of my sister being fucked by some guy. I was pissed at first and wanted to kill this guy but after a few moments my dick started getting hard. My sister looked so damn hot. She was sitting on top of this guy riding his cock. Her tits were bouncing up and down. I had never actually seen her tits before, they were amazing. After a few moments the guy turned her around and was fucking her from behind. My sister kept looking into the camera and smiling. I recognized that this was her room. After a few more moments she turned the guy on to his back and began sucking his dick. The guy must have cum because he collapsed. My sister again looked at the camera and smiled showing her mouth full of cum then swallowed and showed her empty mouth.
