[Fiction] Karma, incest is a bitch.

[Conviction]

This is a long time fetish of mine, I have always wanted to make my sister a slave, but have never gotten the guts, also given her personality she would truly hate it, but it doesn't stop me from fantasizing. The reason that this is my fantasy is because I would need a good excuse to make her my slave with the reasons stated previous, but eventually evolved into something else entirely.

I have deliberately left out our ages, she is 3 years younger then me though, but the grade this would happen in is purposfully left blank.

Warnings for readers (i sometimes see these) includes: age differences, blackmail, exhibitionism, anal, whoring, shame, humiliation, and much much more.

Chapter 1:
It had been a long, LONG day, I was sitting in my room trying to relax. You can probably guess my way of relaxing includes rubbing off as many orgasms as I can until I collapse.
Today I was masturbating to some really kinky stuff, I actually had 3 windows open at the time; one or two gaping videos, a hardcore bondage scene, and some hardcore anal. I came the first time and I was just happy to be done with it, the release was so good I actually came on my own face. What I didn't know was that my sister, who had always been one to fuck with me, was waiting outside of my room with a video camera trained on my dick. I came 4 more times that night, each time my porn got kinkier and kinkier. at times I would swear one of the videos I had paused was still on because I heard moaning, I know now that it was just my sister.
The next day was the beginning of the end for our family ties, but that comes later. that day was a fairly average day, gym was first period, nestled in the hairy ass crack of dawn. second period greeted us with study hall, disinterested teachers browsing YouTube while the students never did any work. Third period was lunch, freedom at last! at least for an hour. fourth period was math, you all know about math class. fifth period, was the most frustrating class of all, french, with a teacher who had a beady eyed stare that could melt a hole through a student's forehead. and lastly, sixth period, language arts, our ditsy teacher practically danced around the room preaching the virtues of voice, imagination, and syntax, before we got to go home.
I lived most of that day like normal, school was as usual, nobody cared and nobody wanted to. My life changed after the bus pulled into the drive way and I got back to my computer to check on my various forums. My room is laid out with my desk facing my door, and my back to the wall, the desk is curved around me with an entrance at the side closest to my bed, the laptop I worked on moved around the desk frequently, most of the kinky possessions I owned and most of my clothes were stored in my closet off to the side of the bed.
as one may imagine, the layout of my room made it extremely hard for anybody to sneak into it. To many, the layout may seem paranoid, but necessary with a sister like mine. this is relevant because when she came into my room that day, she was trying to sneak in coyly, trying to get the jump on me and establish control of the conversation, when she started opening the door and I replied "what is it emmi?" it totally broke that control, the conversation may have been very different if my room had been laid out differently.
"oh..." she replied, taken aback that I had noticed her entrance, she tried to get back into stride as she closed the door behind her "you know what you were doing yesterday?"
I smirked quizzically, she never brought up things like this, it was a more serious topic then she would want to discuss with me. "yea, I remember, what of it?"
she slid her finger on the surface of her phone, an email dinged onto my screen "1 new message from the pest" I clicked the email, fearing exactly what would happen when I did.
The email contained a single link to a porn sharing website, to a video of me the day before, it captured my entire body and the side of my face without missing the action on the screen, If i could have seen my face right then it probably would have conveyed pure terror. despite the tiny voice in the back of my head telling me that my fantasy was coming true, the gut reaction, as it should be, was fear.
"ok, what do you want" I said, my voice slightly shaky as i teetered between elated and petrified.
"oh, not much, do my chores, laundry, clean my room, do my homework, maybe I will even reward you a little bit" her voice and confidence were strong again, especially evidenced by the fact that she had begun openly touching herself at the feeling of control that she was exerting over me.
meanwhile I was letting my mind and body have opposite reactions, my brain was plotting calmly on how to make the magic happen, but my body was trembling and incapable of speech, a moment later, my brain won out "give me a day to think about it" I sputtered.
"what?!?!" she asked indignantly, "i have a video of you, its not your choice"
"or is it, you can kill my school life, but what if I told everybody who was moaning in the background while watching me masturbate"
she paled slightly "OK, 24 hours, you have veto power, after that I will send the video at the drop of a hat"
I mentally fist pumped at the small victory, I knew that in the time until a day had passed she would remove the sound from the video, but it didn't matter, by this time tonight the first part of my fantasy would have been realized.
as soon as she left, I changed her name on my phone from "the pest" to "slave".
