Rose gets throat fucked

Rose is no match for her elder sibling. Marie is stronger than she looks, and utterly determined to remain in control here. You've never seen this side of your sister before, and you don't know whether to be scared or aroused. Scaroused? Was that a word?

Either way, you keep your hands to yourself and one eye on the ever present risk of the driver - whilst you technically have nothing to fear from your step-mom discovering the utter debauchery being committed in the back seat of her car, the last thing you want right now is for the experience to end after only a few seconds. The greatest threat right now is a premature end to the scenario. Whether by luck or fate however, Clara remains utterly oblivious as Marie pushes Rose's head inch by inch towards your dripping, throbbing erection. Rose groans, attempting to twist her head sideways at the last second. Your cock head bounces off her cheek.

"This is happening. Deal with it you little fucking brat," Marie spits venomously at her little sister. "Get. On. That. Cock."

She twists Rose's face back towards you and pushes it down. Rose grabs the seat on either side of your legs and attempts to push back and for a tantalising second, the siblings are at equilibrium as Rose's lips hover over your shaft. A small bead of saliva slowly trickles down over her bottom lip and hangs in the air until it makes contact with your cock. You twitch in anticipation. Oh, god. Your cock was going to be inside your little sister's mouth. This was really happening.

Finally, quivering in exertion, Rose's slender arms can hold her back no more. Straining to the last, they cannot protect her innocence forever. Her stamina drained, they give out and her head is slammed at full **** onto your shaft. Your groans of pleasure are met with harsh, guttural sounds of discomfort as the head of your cock slides across your little sister's tongue, up against the roof of her mouth and finally comes to a braking halt as it slams up against the entrance to her throat.

"No no 'leeease s'op Mhh! N-mmmmmnnn! GAAACKKKKKHHHH!"

With zero regard for Rose's wellbeing, any fears you had about a less than satisfactory blowjob are cast to the wind as Marie flexes her biceps and pushes down hard on Rose's skull, grinding her tonsils onto your cock.

Okay, this timeline's Clara must be either half-deaf or oblivious to the ****, because there is no way in hell anyone could miss the horrendous noises now coming from your new oral fuck-toy. Rose sounds like she's attempting to regurgitate a gallon of jelly, and your crotch is immediately bathed in a thick syrup of clear gag-spit. Your cock and balls are soaked in a soft, warm coating of feminine oral lubrication.

"Yeah that's it, you little slut. Gag on that cock. Lube up that mouth-pussy, nice and wet." Marie laughs.

"Fuck, Marie," you whisper. "I want to teach her a lesson too, but maybe ease up on the girl a little?"

Marie frowns. "Why?" she asks, confused. "I mean, if you really want me to, sure. But-"

Rose's head is extracted from your shaft, the poor girl coughing and moving to wipe her chin. No sooner have her lips left the tip of your cock before they're slammed back down, full ****. And this time they don't stop when your bell-end starts knocking at the front door to her throat.

"Do you really want me to?"

Rose's lips slam into your pubes with considerable **** as she is brutally skewered on your dick. Embedded deep in her tight teen throat, any objections you had disappear in an instant. You look down at your spread legs and the little blonde head occupying the space your cock would usually be. Your little sister's head.

"Uhhh... oh fuck..." you mutter.

"Yeah. Didn't think so." Marie grins. She leans in and gives you another wet kiss, this time right on the lips. Her tongue slips inside your mouth and you find yourself returning the gesture. Alternating between sucking on her thick black lips and exploring the inside of her mouth with your tongue, the waxiness of her black lipstick coats your lips and teeth.

Meanwhile, she's easily holding Rose's head in place as her throat spasms milk your cock. You feel ripples up and down your shaft as she gags, then a wet explosion of fluid splatter across your belly as she exhales a mouthful of spit and pre-cum from both nostrils.

Her head is permitted to withdraw from your crotch long enough to allow her to suck in a half-breath before prematurely being pushed back down. You moan in pleasure, breaking your deep kiss and breathing heavily, face still pressed up against your big sister's pretty - and now somewhat smeared - face. Marie responds by moving your hand to her breasts, encouraging you to push it deep into the soft tissue as she uses her own hands to manhandle your makeshift sex-toy.

Pulling and pushing with increased speed, your cock pops out of Rose's throat with a wet shluuuurkkkk before being pushed against the inside of her cheek. Twisting her head back and forth, her cheeks bulge obscenely as she's **** to pleasure her brother. After thoroughly coating the inside of her mouth with her own gag-spit, you're finally treated to the main course.

The blonde teen's head is yanked back by her twin tails before being slammed back onto your cock, but this time, she's given no reprieve. No sooner has she finished retching, Marie pulls her back and drives her in deep again.

"GACK GACK GACCKKKKK gasp GACCKKKKK -lease GACCKKKK stop GACCCKKKKK!!!"

Slowly building up speed to a frantic pace, Rose has her pretty little head violently skull fucked on your cock for the next several minutes straight. Taking quick breaths when she can, her pleas for mercy soon give way to coughs and gasps as the ordeal she's enduring drains her energy. Finally, she stops taking breaths, instead only able to cough reflexively. Marie doesn't let up the pace, dredging her throat with your cock with savage relentlessness. As the last of the air is expelled from the girl's lungs, Rose resorts to slapping at your thighs.

Marie does not relent. The slapping gets more frantic, but it's not until she starts to turn a deep red and twitch that Marie permits her a chance to breathe.

Yanking her head back by the hair to an uncomfortable looking angle, Rose horks up a giant wad of plegm and cock-spit into the air, which rains down in splatters on her now destroyed face. She takes one ragged breath before coughing horrifically.

"Rose, are you causing a fuss again? Be quiet back there please, or I'll confiscate your phone for the rest of the trip." Clara admonishes her but has yet to turn around, distracted by the length of the traffic jam and currently exchanging some unsavoury finger gestures at the driver in front.

"You heard mom," Marie whispers. "Back to work, slut."

Rose's eyes are lidded and her mouth sags, all the fight gone from her as she's pushed back down onto your shaft. Marie pushes down on the top of her head hard, fully hilting you balls deep in her throat. She grips her on either side of her skull and jerks you off with her face in small, quick and forceful pushes like she's giving CPR, milking your cock in your tight, teen little sister's throat. As you're milked by her rhythmic throat spasms, a watery mix of pre-cum, snot and water dribble from her loose lips and her flared nostrils. Her half-lidded eyes are leaking a constant trickle of tears and look bloodshot from the strain. She looks utterly defeated.

"Uuuhh, gonna cum soon!" you moan.

Marie smiles. "Hear that, you cunt? You wanted a drink, so fucking drink up! Drink your brother's fucking load!" Rose's eyes squeeze shut and fresh tears coat her cheeks as you pump strand after strand of thick baby batter directly into your baby sister's stomach.

“That’s right, chug it you little fucking whore. Chug that thick fucking jizz. Take it all!”

Marie pushes down firmly on Rose’s head, forcing her flush against your crotch until her nose is crushed into your pubes. Rose spasms and snorts. Two strings of thick nut juice spew from her nostrils into your crotch where it pools around her face. Marie giggles softly as Rose squirms and vainly tries to free herself. Cum bubbles froth and foam around the base of your cock as the last of the air is pushed from her lungs into the puddle of slop. Her mouth opens wide as she tries to pull in fresh air, only to suck in a mouthful of testicle sweat, spittle and cum.

Her hands are slapping your legs again now, her movements frantic and panicked but much weaker than before. Marie loosens the pressure on her head enough to allow her to grab the car seat and push herself halfway off your shaft before suddenly and violently slamming her head back down with ****. Rose's tear streaked face makes a wet splat as it impacts your crotch. Cum and throat slime splatters across her entire face, soaks her hair and even covers her panicked bloodshot eyes as she bucks wildly, kicking and slapping at anything in reach. For your part, you groan and also kick out wildly, on the **** opposite of the pleasure spectrum to your poor abused little sister. The post-nut sensitivity combined with an unexpected thrust deep inside a tight sloppy throat forces a second, uncomfortably intense ejaculation out of you. This one is dumped directly down your sibling’s throat with little fanfare - she has no more breath or strength left to expel it.

Marie finally lets go, and Rose immediately jerks back her head with ****, taking a deep, wet ragged breath - slamming her head against the back of the driver’s seat with a loud crack.

“What the fuck is going on back there?” Clara yells as Rose winces and rubs her head whilst coughing up an ungodly river of her brother's nut juice all over the back seat floorboard.

“It was Rose!” you and Marie say in unison, before looking at each other and sharing a smirk. Clara glances over at Rose's empty seat on your left and for a moment you worry that she'll notice that you're naked from the waist down and drenched in Rose's gag spit.

“Stop fucking around and get back in your seat Rose, or I swear to god you’re grounded for a week!” says your step-mom, wonderfully oblivious to the deep, violent incestuous throat dredging her daughter just received less than a foot away.

You hear a gentle tinkling, like wind chimes. Blinking away the weird symbols flickering over the surface of the front car seats like holographic stickers, the world around you slowly fades away. You turn to look at Marie, but she's already cast in shadow and alien runes. You raise your hands only to find you have none. The noise of the traffic dims until you find yourself standing back in the corridor where endless doors await you.
