Two years ago when I moved back into my parents house after college it all started. When I had left home at 18 to go off to school to study engineering I never figured I end up moving back in but, when the job market for engineers dried up I had to take a low paying job and move back in with mom and dad. They were happy enough to have me around again but my baby sister was another story.
When I left for college she was just a little brat of 14 but, by the time I moved back in she had blossomed into quite a spectacular looking young girl. She had just turned 18 and she looked amazing, just as good as the girls I had gone to college with. The months since I had been back had been hell. She took it upon herself to flaunt her new body in front of me whenever she got the chance, knowing full well the effect she had on me. I think the bitch was a real tease with the guys in her high school as well. She went out with a lot of other guys but from what I saw that summer she never put out.
Many was the time that a guy dropped her off at the house and she came right in. I doubt she ever even gave any of them a hand-job. She was just so fuckin stuck up that I wanted to just tell her off, but needless to say I couldn't do that in my parents house. She was going to go to college in the fall and my lucky day had come as well because I had gotten a job offer in St. Louis and was going to move there in the fall as well. I probably would have just left her alone if she hadn't of pulled a really bitchy stunt on the fourth of July weekend.
She and some of her girlfriends had been sunbathing in the back yard and when I came out to mow the grass before going to a buddy's house for a party she looked at me and turned onto her stomach and undid her top. She had really large breasts and seeing them squishing out from under her on both of her sides really had an effect on me and I KNOW she knew what she was doing. That bitch was going to have to pay before she went off to college I just had to figure out how.
The weekend before she left for school I finally decided how I was going to pay her back for her torture. Mom and dad were at work until five in the afternoon and she was busy packing up her stuff to leave for the dorms. She looked so innocent stuffing all of her teddy bears into a box, one never would have known how much of a bitchy tease she was from that scene. However, I didn't let that stop me. She had made me horny all summer and now she was going to pay.
I walked into her room. "Hey there Courtney, do you need any help?"
