"Don't worry. Don't worry. You got this. They don't know it's you," I tell myself in this most unique situation. And boy, of all the things I thought I might do in my life, this isn't one of them.
With both of my parents watching, I grab a better grip of my sister's hair from behind. The two of us are butt naked in our dining room, with my dick buried inside her womanhood as she bends over. And sitting at the dining table are our parents, who both look shocked and scared to death.
Why did they have to come home early? I thought they were going to be gone till the early morning. But no. They had to surprise me by coming home before I was finished. I had it all planned out, except for them coming back early.
My sister made a friend online which promised to do a CNC session with her. Only she has no clue that it was me she was talking to. That I planned all of this, even going so far as to spy on her computer. She thought the session was going to be late tonight, but I decided I wanted more time to play, so I snuck in hours early and started my plan.
For hours I've been abusing and fucking my sister, which has been a life-long fantasy. After all I've been able to do to her, I can die happy. From spanking her, to tying her up, down to making her do depraved and lewd acts to me, it's all been heaven. And she's been the perfect victim the entire time.
Despite the surprise of my parents coming home early, I'm not going to stop. I've reached that point that all men get where they have to cum. They've gone past the point of no return and nothing short of death can prevent us from reaching climax. And judging by the way my gagged sister moans and trembles, she very much feels the same way.
My hips pound Tiffany from behind like a car's pistons, ramming as hard as I can each time. Each time I ram into her, it makes her entire body bounce, which is quite the sight as she's very much still tied down from all the BDSM shit I've done to her. Even those huge bound tits of her's bounce about wildly which happily makes a clapping sound when they land back down against her.
My thrusts become rapid and damn near violent as I feel my orgasm coming. It's built up more and more, fueled by the sight of my parents having to watch me do this to her daughter. For some reason, it makes it even hotter to know they are watching. That they are seeing and hearing her get fucked like an animal, making all sort of sex sounds as she is ravaged.
My sister Tiffany then lets out a wild, loud, high-pitched moan as I shove my cock as deep as it will go in her pussy. At the same time I yank her head backward by the hair, making the entire back of her body against my front. Her moans get louder as I groan a deep guttural groan, with both of us knowing that I've just cummed.
Once again, I cum inside her, pumping my seed deep in her warm pussy, where I mark it as my territory. Even through I've already cum multiple times today, my cock unleashes hell inside of her. It seems to explode with pent-up fury, pumping my seed inside of her faster than I've ever done.
And more than anything, her pussy wants my cum. Even after it's been fucked raw, I feel her rocking her hips as if trying get my cock to go deeper. She wants this, as much as I do, even if she wants to believe she's being forced. Through she stopped being forced quite a while ago. Now she's just a willing participant.
A cascade of emotions flow over me as I cum inside my sister. Pleasure, shame, power, embarrassment and so much more. Then the fear hits me. As I bury my cock in my pussy, the fear that my parents are going to know it's me rushes over my mind. That they will figure out that it's their son that's just raped their daughter. I'm not sure how they will know, maybe the way I stand, or walk or something but I fear they will. Sure, I have a mask on and even changed my eye color, but I just fear they will somehow know it's me.
My tired manhood finally stops cumming, leaving me feeling tired and spent. It comes over me with the rush of emotions, making me feel like I could lay down and take a nap. I've never been so sexually fulfilled before.
Letting go of my sister, I see how far I've gone. How much I've done to her. Her naked is on display for all, showing every single little thing that I've done to her. I've abused her all to hell. It'll take her weeks to heal after all that I've done to her body. Not that I've cut her or punched or anything, but I did do so much harsh BDSM to her, which she loved.
Worry begins to plague me as I hold my fake gun towards my parents. I've been pointing it at them the entire time as I think it's the only thing keeping them sitting at the kitchen table. My fear at doing this is they might figure out that it's a fake gun. Neither of my parents are what you would call gun people, but they are smart. If anyone could figure out it's fake, it would be one of them.
I have to fight from biting my lip as worry takes its hold inside me. Keeping myself looking stern and in charge is perhaps the hardest thing I've ever done. Oddly, being completely naked helps for some reason.
How in the hell am I going to get out of this? I've fucked myself pretty bad here. It was just supposed to be my sister and I. If it stayed like that, everything would have worked out as she probably wouldn't have said anything since she thinks this is a CNC roleplay with a stranger. I could have done even more than I have to her, but it's all gone to hell. What the hell am I supposed to do about my parents?
I would love to just grab my clothes and run out of here, but I can't. The big issue that is going to come back to bite me is that I've cum inside my sister a few times now. That means I've left DNA. DNA that can be traced back to me. And that'll be the first thing my parents will make my sister do, which is go to the hospital so they can get a sample. There's no way I can explain my DNA being inside of her outside of admitting that I fucked her.
I need to somehow make that DNA untraceable. That way if they get a sample of it, it won't be used. But how do I go about doing that? Despite how rough I've been with my sister, I don't want to hurt her. So I'm not going to, you know, put anything inside of her that might damage her or her insides.
My worry grows as there's only one way I can think to make the DNA unusable. Well, one way that isn't cruel or dangerous. And it's not going to go over well with everyone, at all.
Acting much tougher and more dominant than I feel, I look at my father. When I do this, I'm very surprised to find that my dick is still buried in his daughter. I thought I had taken it out, but clearly I didn't, unless it somehow magically found it's way back, which at this point I wouldn't be that surprised.
