How my sister became my sex slave. Intro

My name is Adam and my sister's name is Mary. I am 5 years older then my sister. I was planned and well she wasn't. I lover her to death she is just amazing. Now let me tell you how she ended up being my very own personal sex slave. It all really was an accident. It all started when I started to go though purity. I was horny all the time so spent a lot of time in my room jerking off. Since my sister was innocent she happen to walk in on me now and then. At first I would tell her to get out because I was busy. Her being the innocent girl and curious soon learn when to come into my room. At first she would as what I was doing and I just told her to get out that I busy. After a little while I knew she would come in on me and was hard to get privacy. One day while I was close to done she burst in wanting to play. I didn't notice because I was so close to cumming. When I started to cum she was next to by bed watching as cum shot out of my dick. She let out a small scream and I saw she was there. Then she said "Eww you pee yourself!" Without thinking I quickly told her to be quite someone might hear. Still with my now dick in hand. Once I realize what happen I tried t grab a sheet but they were all on the floor and my sis was standing on them. She then started to ask "Why are you always pulling at it, every time I come in you are pulling at it." Not knowing what to do I just got up and put on some boxers and grabbed a sock go clean up the cum. "Just leave my room okay. Oh and how ...

... many times must I tell you to knock." I told her trying to avoid the questions but my sister being herself didn't and just kept nagging me. "Okay! If I tell you what I was doing you must leave me alone." I finally gave in because she would end up asking our parents also and tell them what she saw if I didn't end up explaining everything. "So what I was doing is called jacking off. Guys do it all the time because we have to or else it hurts us when we don't." Without a pause she ask "Why?". "Like I said if I don't do it then it will hurt me and I won't be very happy. As for what came out it is called cum and it is nothing like pee. Happy now?" She left it at that because she could see I was getting annoyed and wouldn't answer any more questions. Rest of the day went by without any mention of what happen. I was happy thinking she had forgot moved on! The next day after I got home I quickly made it to my room to jerk off. Soon after my sister comes in and sees me I quickly cover up and she just ask, "Your jerking off again?" I say yes and to please let me finish. She hangs her head and goes out but what I didn't see she didn't complete close the door on her way out so she is now watching me as I jerk off and soon cum. Some time goes by and now my sister just watched me from the crack on the door when she opens it. Soon I realize and let her keep doing it. At a point I even start to enjoy it. Then one day as I start to jerk off I just say out loud. "Come in here and watch since ...
