"What the hell are you doing Brad?" Shouted my younger sister Jackie as she walked in on me jacking myself off in her room. I stopped and looked at her, and I looked at her real good. She was 5’1” with short dark brown hair and a body to die for. She had gotten into a lot of fitness crap in the last year and had really toned her body up. That is when I started to notice how hot my 15 year old sister was. she had average breasts and the tightest ass I have ever seen. I had tried to sneak a peek before but I had either been caught or I just missed my chance. I decided right then, this was going to be it.

“I was really horny so I decided to use your underwear to help me get off like I usually do when you aren’t here” I replied to her. “Ugh, so that is what I have been finding in my underwear this whole time. Jesus, what the fuck is wrong with you? Put your pants back on or I’ll tell Mom.” Oh no she wouldn’t . I quickly crossed the room grabbing her around her body pinning her arms to her sides and put a hand over her mouth. I brought her into the room and closed the door hoping that would prevent anyone from hearing her momentary scream in a second. I release her for a second and grab some of her underwear for binds. She immediately screams for help and I am there right away. I wad up some of her panties I had already came on earlier and shove it into her mouth. I then use a loose shoelace to tie it in place for now. next I tie her arms together with some tube socks and throw her on the bed. I know exactly what I will do next and what I’ll need.

I go into my room and grab my sets of handcuffs I had ordered two weeks earlier and I grab my new gag with them. Before I go back I make sure to grab my hunting knife and check it’s sharpness. When I enter Jackie’s room I find out she had quieted down but soon started up again when she saw the knife. I go over to her and handcuff her spread eagle to her solid iron bedposts. next I re-gag her and throw away the makeshift gag. Now it’s time for me to see my sister naked.

“Do you know what I have wanted to do to you? You must know with how you have been taunting and teasing me this whole time. I know you have been a little whore and fucking every other guy, so why not me?” I don’t pay attention to her trying to deny it, I know I’m right. “ I want to see you naked, then I’m going to fuck you. I’m going to fuck you like there is no tomorrow Jackie. But first, we need your clothes gone.” I had been hunting before and had skinned deer and this was something like that. Let me tell you, after this, I never skinned a deer without thinking about Jackie again. I took my knife and put the blade under her belt. It took almost no pressure at all to slice through it. I next went to work on her shirt while Jackie sobbed quietly. “If you don’t shout up and stop moving I might accidentally cut you, and neither of us want that do we?” She shakes her head no fervently and I continue. I remove the shirt and find a pink lacy bra underneath. Just to give myself more of a chance to get hard again, I decide to remove her pants before her bra. I slice clean through her jeans to find she has pink lacy panties to match the bra. Maybe she thought something was going to happen with someone. Now it was time to treat myself.

Using the knife I quickly tore through her bra to find the nicest tits I have ever seen, much nicer than any of my girlfriends’. Jackie is just staring at me and trying hard not to make a sound or move as I trace my knife down from her throat between her breasts, around her belly button and finally around to her hip. With a quick motion I cut through her panties to reveal her pussy. She apparently has never talked to anyone about shaving or anything because it is like a jungle down there. I rub my hands over her pussy and I get a moaning sound from Jackie. Apparently she likes this to some degree. I quickly remove my clothes and position myself over her with my 7” dick rubbing against the entrance to her hole. I try to look her in the eyes but I see her pleading to me with her eyes. I stop looking so that I don’t suddenly grow a conscience or anything and I get ready for the big plunge.

“I am about to give you something really great you whore. I am goanna share my dick with you now so you better be grateful. I really hope you enjoy this as much as I will.” And with that I shove my cock in as hard as I can and in doing so, I break the hymen I thought she had lost a while ago. She screams in pain and I don’t know what to do other than just continue and fuck her for all she is worth. So I grab her tits and squeeze them as I pump I and out. I can feel her pussy grabbing and squeezing my dick back. As I go faster I find a position I can hit her sweet spot with and go for it. If it is her first time, I might as well do something for her. As I keep fucking, her cries and screams turn to moans and grunts. I can feel it, I can feel my orgasm coming. I start to go faster and faster as it comes and her pussy gives one final squeeze as she starts to cum and that is when I lose it. I cum deep inside of Jackie’s pussy, making sure to fill it with my incestual seed.

When I collapse onto her after I finish, I notice a tear going down her cheek and look down to see her blood all over the place. I go to get a towel and clean her off, making sure to throw away the sheets and replace them with new ones. I look down at her again and see how fucking gorgeous she looks naked. I start getting a hard on again and I also get another idea. I undo the handcuffs and she just lays there staring at me. I flip her over and cuff her hands behind her back and bend her over in a kneeling position. I notice she started getting wet again and I rub my cock around her pussy getting it nice and lubed up. Then I place the head of my dick on her ass and start to push. She must have not know what I was doing because now she was screaming again probably trying to tell me that I could fuck her pussy again just don’t screw her ass. Well, I was raping her so it didn’t really matter what she wanted.

I shove my dick in farther and I can feel the muscles in her ass tightening around this unwanted invader. I didn’t care, that just meant it would be a lot more fun. I shoved my dick in hard as far as it would go and Jackie screamed again. I just held it there for a while and massaged her tits while her ass got used to my cock. After about two minutes, I start to fucking her ass. I am just going at it having the time of my life with her. while I am fucking her, I grab a hold of her short, boyish hair and hold onto that as I am fucking her. I tell her “You are my little cock-whore now” or “I am going to fuck you still you are completely filled with cum.” As I am screwing her I realize that if I could get her to cum, her ass would squeeze my dick better than her pussy did. So I releas her hair and lean forward to start massaging her clit. As I go at it more she starts moaning again and bucking back against me. It is only another minute before she has another orgasm and I am filling her ass with my cum.

It seemed to last forever. I must have shot a gallon of my wad up in her ass before I was done. I get off after that and look down at her again. I decide to take the gag and handcuffs back. I see that she doesn’t have any marks on her wrists. It is a good thing she didn’t really fight the handcuffs, that’s just one more thing against her if she decides to tell anyone. I give her a kiss on the lips and she doesn’t respond at all, she doesn’t even blink. So I decide for one grand finale before I get out of here and I start to rub my cock. It isn’t too long before I get it up again and I start to jack off again using one of her panties. It feels good, but not as good as her pussy or ass. It doesn’t take long before I start to get that old familiar feeling and I shove the head of my dick in little Jackie’s mouth. I spray some in there and pull out to finish Cumming on her face and chest. I then grab her head and hold it up and massage her throat while holding her mouth closed. Eventually she swallows it and I let her fall limp back on the bed. With being totally satisfied, I put my clothes back on and head next door to my neighbors’ house. I get to baby sit tonight.
