Work Text:
Your eyes flutter closed as you balance on tiptoes with the pointy tip of the knob teasing against your lubed up asshole. You let your heels drop a little, and you can feel the lacquered wood ornament spread you open slowly. A low moan drifts from your parted lips when you lean back more and another inch slides into you. It sounds a suspiciously lot like your step-brother's name. A bit more, and you're fully seated on the top of the bedpost with a content moan.
But your enjoyment is short-lived with your step-brother, Mason, who wasn't supposed to be home yet, flings open your door without knocking. You try to cover up with your arms as his eyes roam over your naked body, but you're like a deer caught in headlights as he stalks across the room before you could climb off of the bedpost. "I-It's not what it l-looks like!"
"I don't know, sis," and that last word is carrying a wicked amusement — though the shiver along your spine doesn't entirely feel like as that of apprehension when his hands grab your hips. "It looks just like that."
The words sending him to hell freeze in your throat when he pushes you back down, forcing your ass open around the thick knob. Your fingers grasp at his shirt; a feeble anchor in the storm of disgust and arousal. This is wrong, you're siblings of sorts — but by God, do his hands feel amazing on your body.
A deep breath, a shake of your head, and you use the bunched fabric to shove him away; try anyway. He stands firm in front of you, clicking his tongue at your stubbornness. When he moves it's not away but closer, enough that you can feel his warmth and breathe in his scent (pine, citrus, and something you can't tell). He's towering above you, even more when he kicks your feet farther apart and you can feel the bedpost widen into the next decorative section between your cheeks.
"Nothing to say, sis?" Oh, there's a lot you want to tell him — but all the sound you manage is a meek, vaguely delighted whimper when his fingers run along your damp folds. "Then you won't mind holding this, do you?"
"Wha-" But the moment your lips part, he's stuffing the panties into your mouth as an impromptu gag, and all else you want to say comes out as only a muffled groan. With your hands caught, your tongue fights to push it out — but all you manage is a taste of your own slick off your panties.
"Lace really suits you." His fingers angle your chin as he holds you still, smirking only at your pitiful attempt at a scowl. You swear to yourself he's not going to get away thi- Oh, fucking hell!
His hand drops back down to your folds, fingertips teasing against your leaking entrance; sliding into you smoother than you'd like. His fingers pump in and out with a flick of his wrist, and wet sounds start to mix with your muffled swears. He's too good at finding the spots that make your voice crack — though maybe that's just his thumb catching on your clit each time his fingers push in deep.
The only thing he doesn't do is adding another finger, not even when you try to beg through your gag that's by now dripping with your own saliva. Or even if he could just hit that spot again...
You tense for a moment as that thought occurs — you shouldn't be enjoying this. The way his fingers stroke a fire deep in your pussy. The biting little kisses just low enough on your shoulders that most clothes would cover. Even his grip holding your arms tightly behind your back is heightening your pleasure instead of causing pain. And when he stops, giving you a curious glance, you find your hips already moving on their own. "You want to cum, don't you, sis?"
You frantically nod when you should be screaming bloody murder — you've never felt this desperate in your life to come. But instead of flexing his fingers or thumbing at your swollen clit, he steps away. From somewhere (is it his pockets? did he come prepared?) he pulls a piece of rope to secure your arms behind you back with.
Giving both his hands free run of your body sounds equally frightening and exciting — if only he'd touch you, too.
With fluttering eyelashes and a muffled plea to just please let you cum, you watch as Mason looks through the spread of toys on your bed. He makes an off-hand comment about how you should've left him play with you sooner as he lifts up a rather lengthy string of beads. You shudder at the thought that this could become regular, still unsure how to feel about the whole experience. You're starting to see again how wrong all this is — but damn if he doesn't know how to make you squeal in delight.
"A vibrator? Is that what you want in your pussy?" You watch as he grabs at the bulge in his pants. You do hope he can't hear how loudly you swallow. "How about a nice, juicy dick instead?"
You try to answer but through the used panties stuck in your mouth, it's all just a series of muffled sounds that make no rhyme or reason.
"Speak up, I can't hear you." His lips brush against the shell of your ear as he whispers, fingers splayed across your throat to keep your head still. Your heavy swallow presses against his palm, and you swear you see him twitch in his pants.
You'd hit him if you could but your arms are still bound behind your back, and all you can do is watch him undress. Lean muscles flex as he pulls the shirt over his head, ruffling up light, golden curls you'd die to run your fingers through if he weren't your step-brother. Not that it stops him from having his way with you. The bulge in his boxers, wet around his tip, looks even more imposing when his pants come off. And he's big.
A soft patch of dirty blond circles the base of a long, veiny dick. Its girth can probably unhinge your jaw if you're not careful enough. The leaking tip pokes out from between wrinkled up foreskin — you pray he washes up well. His balls look heavy, hanging below an already fat dick. Straining, full of cum. He palms at his dick as if he needs it any harder — you watch mesmerized as his hand moves. You don't think you can bend low enough to lick up the drop that spills.
He guides the tip between your folds, spreading them open with a light cant of his hips that has your slick mix with his pre-cum. A sigh falls from your lips when the head nudges your swollen clit. His fingers grasp your chin, forcing your half-lidded eyes to meet his gaze. "Tell me what you want, sis."
You have trouble finding the words when his dick nudges your clit again. His fingers dig into your face when you aren't clear enough. Half a hiss forms in your throat before he palms at your tits, turning the sound into a whiny moan. You try again. "Please fuck me."
Angling his dick against your entrance, you can't help but wonder if it's really consent, or submission he wanted to hear from you. Not that it matters when the fat head slides in and you almost choke on your own saliva. He's spreading you open wide, fighting for each inch with you still perched on the bedpost. Hands drop to your hips for leverage but even that's not enough to fully settle his dick, and he needs to lift your leg over his arm to bury himself to the hilt.
"Nice and tight for your brother, huh?" It almost feels like your first time again between his size and the wooden knob bulging in your ass. A soft moan is all your answer when the head twitches, rubbing at a sensitive spot that has you shudder. "That's it, keep those sounds coming as I fuck your pussy open."
It's not that you obey, but there's little else you can do than gasp and hold onto him (when did the ropes come off?) when Mason starts to move. Each thrust is smoother and quicker than the last, spreading you open all the way down to that sensitive spot. Swears, pleas, and his name mix on your tongue between sloppy kisses and whorish moans. He gathers up your other leg after a few thrusts, letting fall onto his dick all the way with each pump until you're dizzy from the bouncing, pleading in a breathless voice to put you down.
There's a scream on your lips when he lifts you up higher and your ass comes off the bedpost in one swift motion stretching you wide open. You're still reeling from the sensation that's equal parts pleasure and pain when your back hits the mattress and you're staring up at your own ceiling before Mason climbs over you, sinking his dick deep while his heavy balls smack against your gaping ass — you drool at the though of it all filling you up. Good thing you're on the pills.
Thoughts of safety go as quick they come, and you're moaning and whimpering again as Mason presses your knees into the bed by your head, allowing him to fuck into you harder and deeper. In, out, in, out, and soon you're losing count how many times he hits that sensitive spot (almost as many times he ruts into you) that has you grab at your sheets with a shudder and the arch of your back growing tense. "Do-don'chu. Fucking. Ssstop."
Your words are slurred together as you brace against the bed, bucking your hips up against Mason — or as much it's possible with your ass up in the air, filling the room with wet smacks as his sweaty balls bounce against your stretched hole. The sound is starting to replace the rhythm of your shallow breath. Your vision is hazy, eyelashes fluttering leisurely while your heartbeat races; but you can tell Mason is close to breaking. You've never had a shared orgasm before.
"C-cu...cu-cumm..mhing..." you stutter out between a needy moan and strangled scream as your limbs tremble, and your spasming walls try to hold onto Mason's throbbing dick rutting into you with abandon. Something warm and watery splashes onto your thighs as you shudder, gasping for air — is that what you think it is?
"Look at you squirting from your big brother fucking you." His fingers grasp your hair, guiding your blurry vision to your leaking pussy — and you almost feel like coming again watching as his big, veiny dick slides in and out. A few more sloppy and squelching thrusts, and Mason bottoms out with a low groan; pumping you full of fresh, warm cum.
Regaining a semblance of sense and consciousness, you squeeze your pussy tight around him, hips swaying slowly to help milk every last drop until his dick stop thrumming against your trembling walls. He stays there for long seconds, watching as his cock softens and some of his cum leaks out when your numb legs drop to the mattress.
You don't feel like moving any time soon — even thinking feels difficult. You've just been fucked and filled by your stepbrother. And fuck it, you enjoyed every moment of it. His hold over you; both mental and physical. The size of his dick pounding your tight pussy. The dirty, little things he's said and how he kept calling you sister — you'd hate to admit how much more aroused it made you.
Aftershocks have you jerk away when Mason leans over you with his softening dick teasing between your folds, and again when his fingers dip into your pussy to bring you a taste. Salty, slightly bitter — yet you already know you'll be swallowing it down like the sweetest nectar every time he wants to spill his load between your lips. "You can come back for seconds any time, sis."
