Annie the 'bad' girl : Part one

Note : This story is completely fictional!

My siter (Annie) always has been a nice girl up until a couple of years ago. Before she started to turn badshe was in the choir and boy she had the most amazing voice. Annie's voice sounded beutifull like smooth waves smashing against the shore. She always was doing very good in school. Annie always got into honor roll. But that was when she was in seventh grade.

Now me and my sister are in high school. It was really lucky to get a room that I had to share with my sister. Annie has nice long sandy blonde hair. Her titties are the size of grapefruits.

She dates a kid who gets drunk almost all the time and asks my sister to have sex with her even thuogh I am in the room with her. Annie just looked at me and didnt say a word. She had a worried look on her face. I was suprised to see her worried face because almost all the time she would boss me around. I asked whats wrong and she said "He is ugly!" and then I said "Why did you date him sis, your broken or something?" She then walked up to me while her date knocked out on the couch. She said "You try to act all perfect with the golden boy attitude. But I know what you are. You hate to be that. You just want to be free."

"You are right. I am a total hippocrit." I replied. She then woke up the guy and asked him to get out and said Im Through. The guy had a hurt look on his face. "Your a bitch." he said then stumbled out of room. My sister shook her head and closed the door behind her.

She then ripped my shirt off and gave me a purr which made my cock as hard as hell. I then growled back and pushed her ontop of my bed. I then said "Do you have a ruber?" She then got up and said "You mean we cant have intercourse? I have wanted to fuck you ever since we got this place and you treat me like this?"
