big sissy is always so mean to me when no one else is around! whenever mommi and dadi leave her to babysit me, she rips my clothes off, ties me down to her bed, and puts a vibrator inside me. she puts it on the highest setting and rubs her princess parts while watching me squirm and beg her to turn it off. when she finally turns it off, she unties my limp limbs while i pant breathlessly. she positions herself to grind her princess parts on mine saying that:

“i’m not done with you yet, pretty girl~ big sis has to get her fill in too so just stay there and let me use your slippery slit until i’m satisfied, ‘kay!”

all i can do is cry and moan helplessly with no thoughts in my head as she uses my cunnie for her own pleasure.

by the time mommi and dadi get home, i’m fast asleep and big sissy is telling them how good i was while they were gone, earning endless praise from them and being told how she was always the best at tiring me out.

acting like a brat all day until daddy finally snaps and has to remind me that: “you’re just a little slvt who is nothing more than my own personal fvck toy. now stay still and let me remind you of your place.”

gosh! just thinking about daddy’s stern voice and sharp glare makes my cunnie soak so fast!!

mommi woke up while i was sucking dadi's special lollipop in his sleep. i thought she would be mad but she encouraged me to keep going and even braided my hair back while I bobbed my head up and down. after dadi's lollipop was lubed up with saliva, mommi got nakie and showed me how she plays horsey on dadi's lollipop to make white icing come out! she told me to get nakie too and then let me try playing horsey! my body felt so hot and my k1ddo parts started to swell until dadi's white icing shot completely inside me! i didn't know how I was going to get it all out but mommi said she knew the perfect way to clean me all up. she licked all of dadi's icing out of me and then sent me off to my room making me promise not to tell dadi a thing.

the next morning, dadi complimented the braid in my hair, and I couldn't help but flush bright red, remembering the night before. but feeling the slick in my panties makes my embarrassment go away and be replaced by fuzzy feelings in my tummy and k1ddo parts.

now, i can't wait for bedtime~..

i love walking around my house nakie. no clothes, not even panties or a bra on. just doing everything I would normally do around the house just with a lack of clothes. i'm practically a freeuse, nakie toy for anyone who comes over. i wish walking around nakie was normal so I could be a freeuse toy for the whole world to use however they desire.

“I dunno, it feels kinda weird,” you say, leaning your head against your arms as you curl on one end of the couch. Your older brother, on the other end, lets out an exasperated groan. You hope it is an exasperated one, anyway.

“C’mon. I’m not asking much from you, here.”

“…Except for…” your eyes drift down his body to the blanket on his lap. It fails to cover the rhythmic movement of his hand, and you wonder why the two of you ever thought it would.

“…Well. Sitting here and being a… an… inspiration,” you grit through your teeth and tear your eyes away from him entirely.

“Ok, yeah, fair point,” he grunts, and from the corner of your eye, you can see him reach his other hand under the blanket as well, “And you know, I’m— I’m thankful, really…”

He hisses something under his breath, “fuck” most likely, and you try to keep your eyes strictly on whatever 80s horror movie you have playing on the TV. Some guy just got stabbed by an Alice Cooper -looking hobo, probably possessed by Satan, but you still find yourself glancing where you shouldn’t.

You hate that you can’t even blame this idea completely on him. Obviously, it’s him out of the two of you who wants to jerk off to the sight of his sibling. He begged it from you, assured you that you’d be safe, that he wouldn’t touch you — and truthfully, he hasn’t. But it’s you who gave it the go, talked about him letting it out, once and for all, an exorcism of the feelings that plagued him.

“But it would make this quicker, y’know?”

When you turn to look at him, there’s a wry half-smile on his face. You make the mistake of glancing down, at his lap, at his hand moving up and down under the blanket, stroking—

There’s teeth in that smile when you look back up at his face.

“Unless you want this to last longer?” he asks, the teasing grin and wiggling eyebrows unable to hide how hopeful he sounds.

“Wh- No! Christ! Of course not!” you cry out, indignant and your face too hot. You have half a mind to hit him with a pillow. Of course you don’t want this to go on any longer than it has to, what kind of person would?! It’s already bad enough to know that your own brother is looking at you like that, that even now he’s probably wishing he could just press you down on the couch and—

No. None of that.

“Why do you even need me to call you that? I never call you ‘big bro’. No one calls their brother ‘big bro’.”

Is his hand starting to move quicker?

“‘Dunno. Sounds hot,” he says heavily, “C’mon… Just say it. Please?”

He’s leaning forward on the couch, and his eyes are fixed on you so intently that you can’t look away. Some part of you fears that if you do, he’ll just… pounce on you, like some stupid dog that thinks looking away equals submission equals permission.

You do want this to be over with sooner rather than later, don’t you?

“…‘Big bro’,” you mutter. It sounds awkward. Stilted. Reading the lines of a teleprompter.

“Like you mean it.”

Something knots at the bottom of your stomach. Something inside you quivered just now to the deep, growling cadence of his voice.

”Big bro,” you repeat, like you would say his name, and you watch eyes wide as his flutter closed for a second, and a throaty whine leaves his throat.

“Yeah, yeah, keep saying that…”

“You… you want me to just repeat it or… or keep talking or what…? Big bro?” you ask, and try to keep your eyes on his when they open again, and not an inch lower.

“I’d have thought that that would just make it weirder for you, like, just underlining that we are family, how—” your words halt with a realisation, and you curse under your breath, “Fuck. Fuck…”

He blinks, eyes suddenly just a bit darker and more intense as he stares at your shocked face.

“You like that?” you ask, your voice fragile, a question you don’t want an answer to but you have it before the words even leave your mouth.

“…Can’t say I mind it.”

The understatement of the century.

“You like being reminded that we are siblings?” the words feel sticky on your tongue, but they rise unbidden before you can stop them, “I thought you’d have wished that we weren’t, so it’d actually like… like theoretically be possible for us to— but you actually like it, don’t you? You like that you’re not— that I’m not just some… some random pretty girl but your sister, big bro?”

You don’t understand where these words are coming from. Judging by his wide eyes, he doesn’t either. A grin, giddy and apologetic in equal measure, spreads on his face as his hand starts to move faster under the blanket, and you begin to fear it falling, having to see what you are causing, him with his cock out and hard for you.

“Fuck, yes, don’t stop…!”

You fear what that sight would do to you. It’s already bad enough that you can’t tear your eyes off of your big brother, how that familiar face twists into an expression you have never seen before, and shouldn’t have ever seen. His eyes almost flutter closed, but not quite, their dark gaze burning and never leaving you. His mouth hangs open, not quite an ‘o’ shape and more like the open-mouthed grin of a canine, piercings and teeth glinting sharp in the cold light of the TV.

“Jesus— Fuck, this is really what turns you on? Making your little sister watch as her big brother jerks off to her?” you hear yourself whimpering, your voice sounding breathier and much less disgusted than it should. You hate that you find yourself wondering what marks that wolfish mouth would leave, and you hate the longing, warm ripple between your thighs.

He’s cursing under his breath, in between the animalistic groans and whimpers. Strings of “fuck, fuck, fuck, baby sis” interspersed with your name. His hips are bucking, you can even see his leg kicking under the blanket. And when he leans back, his spine arching against the back of the couch more beautifully than you’d have ever imagined from him, you can barely breathe.

“Is your baby sis making you cum, big bro?”

You have your answer in his eyes, wide before they roll back in his skull. In his hips that stutter up, in the wet, growing stain on the blanket. In the tongue that lolls out from between his sharp teeth, a red carpet for all the throaty, helpless sounds of a man cumming his brains out.

He slumps against the couch, boneless and exhausted, a stupid, drunken smile on his lips. You just made your own big brother cum his brains out.

And when he turns to look at you, bliss written all over his face, you know it won’t be the last time.
