Sister surprise

The doorbell rings at three in the afternoon—a sharp, ordinary sound that makes your stomach clench with immediate dread. You and Sarah are kneeling in the living room, exactly where Alina left you, your throats still sore from the morning's throat-fucking, your assholes still leaking her seed from the dawn breeding session. You are dressed only in your submission, your nakedness a testament to your permanent status as her property.

"Expecting someone?" Alina purrs from the kitchen, her voice carrying that dangerous playfulness that always precedes her taking what she wants. She moves toward the door with predatory leisure, her body barely concealed in tight black leggings and a cropped tank top—outfit chosen specifically to display her assets, her dominance, and her power.

You hear the lock click. The door swings open.

"Oh! I'm sorry, I must have the wrong—" A woman's voice, familiar, startled. "I'm looking for Sarah? I'm her sister, Amanda. I was in the neighborhood and thought I'd surprise—"

The words die in her throat.

You crawl forward on your knees, risking a glance around the corner, and you see her—Amanda, Sarah's younger sister, thirty-five and prim in her conservative blouse and pencil skirt, her blonde hair pulled back in a severe bun. She's frozen on the doorstep, her eyes locked on the impossible sight before her, her face draining of color, her mouth trembling.

Alina hasn't positioned herself to hide anything. The waistband of her leggings sits low on her hips, and her cock—thick, fully erect, veined, and dark against her tan skin—sticks out over the top, the tip glistening with precum, bobbing heavily in the afternoon light. The outline of her massive shaft strains against the fabric, undeniable and obscene.

"What... what is this?" Amanda stammers, taking a rapid step backward, her eyes wide with horror, her hand reaching behind her for the doorframe. "Sarah? Are you here? What's going on?"

She turns to flee, her sensible heels clicking against the porch, but Alina's voice cracks like a whip: "Grab her."

You move without thought, your body obeying before your mind catches up. Sarah moves with you—both of you scrambling on hands and knees across the hardwood floor, reaching the doorway in seconds. Amanda shrieks as your fingers close around her wrist, her body recoiling, trying to jerk away.

"Let go of me!" she screams, her voice high and panicked. "Sarah! Help me! What the fuck is happening?"

But Sarah doesn't help. Sarah takes her other arm, her grip iron-tight, her eyes gleaming with a dark excitement you've never seen before. Together you drag your struggling sister-in-law into the house, Amanda's heels digging furrows in the carpet, her body twisting, her purse falling to the floor with a crash.

"Stop it! Stop! Let me go!" Amanda thrashes wildly, her conservative bun coming loose, blonde hair spilling across her face. "This is insane! Sarah, what are you doing? He's hurting me—"

"Be quiet," Sarah hisses, her voice cold and foreign, nothing like the sister Amanda knows. "Stop fighting. It only makes it worse."

You force Amanda to her knees, but she fights you every inch—elbowing you in the ribs, trying to scratch at Sarah's face. It takes both of you to wrestle her down, pressing her shoulders until her cheek is against the carpet, her ass raised against her will, her skirt riding up to reveal conservative white panties.

"No—*no*—get off me—" Amanda sobs, genuine tears streaming down her face, her body rigid with terror. "Please—I'll leave—I won't tell anyone—just let me go—"

"On all fours," Alina commands, her cock thickening further as she watches you wrestle Amanda into position. "Hold her down. Don't let her move. She tries to get up, you pin her harder."

You force Amanda's knees apart, spreading her as she kicks backward, her sensible heels narrowly missing your chin. You grab her wrists and pin them behind her back, your full weight pressing down on her shoulders while Sarah straddles her lower back, pinning her hips to the floor. Amanda bucks like a wild animal, her spine arching, trying to throw you off.

"Sarah, please—" Amanda begs, her voice breaking, snot mixing with her tears. "I'm your sister—please—don't do this—"

"Shhh," Sarah purrs, but there's no comfort in it—only dark promise as she reaches beneath her sister's body, finding the waistband of her panties. "Stop crying, Amanda. You're only making it harder on yourself."

"Don't—*don't touch me*—" Amanda screams as Sarah strips the panties down her legs, tossing them aside. She fights harder as Sarah unbuttons the skirt and slides it off, leaving her naked from the waist down, exposed and vulnerable, her pale thighs pressed together in a futile attempt at modesty.

"Spread her," Alina orders, positioning herself behind Amanda.

Sarah forces Amanda's knees apart, revealing her untouched pink cunt and the tight rosebud of her asshole clenched in terror. Amanda tries to clamp her legs shut, but Sarah holds them open, her fingers digging into Amanda's inner thighs, holding her spread for Alina's inspection.

"No—*please no*—I can't—it's too big—" Amanda whimpers, her whole body shaking violently, her face turned away in shame. "Please don't—I'll do anything else—just not that—"

"It'll sting just a minute," Sarah whispers, her lips brushing Amanda's ear, her voice dripping with betrayal. "Your pussy needs stretching, baby sister. And Alina can do that for you. She's so big, so thick, so perfect. Maybe you even want to have a bastard baby from her? Wouldn't that be delicious? Getting knocked up by your niece's cock?"

"You're crazy—*you're both crazy*—" Amanda sobs, her muscles tensing as she feels Alina's presence behind her, the heat of her body, and the weight of her cock dragging against her thigh. "Please—I'll leave the country—I won't say a word—"

"Oh really?" Sarah continues, her voice dropping to a seductive murmur as she spreads Amanda's cheeks wider, presenting her holes to Alina. "She's going to tear your ass open too, you know. She's going to use every hole you have. And you're going to thank her for it. You're going to beg for more, just like we do. Just like Daddy and I do every single day."

"Never—*I'll never*—" Amanda chokes out, but her words cut off as Alina grips her shaft and presses the massive head against her unprepared entrance.

Alina moves into position, her leggings shoved down to her thighs, her cock swinging heavily, the head flushed dark purple, veins standing out in thick relief. She drags the tip through Amanda's dry folds, forcing her to feel the heat and weight of it, the impossible girth that will soon be inside her.

"Hold her tight," Alina commands, gripping her shaft and positioning the crown at Amanda's resisting entrance. "This is going to hurt. She's going to scream. Don't let her go."

She begins to push forward.

The penetration is agonizingly slow, deliberately cruel, a battle against Amanda's clamped-shut body. Alina's cockhead is enormous, thick as a fist, and Amanda's cunt is dry, terrified, and fighting the invasion with every muscle. Alina presses forward relentlessly, her hips rolling, forcing Amanda's pink lips to stretch obscenely wide around the impossible girth.

"Stop—*stop it hurts*—*please*—" Amanda screams into the carpet, her back arching violently, trying to buck you off, her hands clawing at your grip until her nails draw blood. You hold her firm, pinning her wrists behind her back, your knee pressing between her shoulder blades, keeping her face down and helpless as Alina continues her slow invasion.

"So tight," Alina breathes, her hips rolling forward, feeding inch after inch of thick veined shaft into Amanda's resisting body. "Fighting me. Clenching. But you're taking it anyway, Auntie. Taking every inch like it or not."

The stretch is brutal—Amanda's cunt lips wrapped tight around Alina's girth, whitening with the strain, the shaft disappearing slowly into her body despite her sobs and pleas. Amanda throws her head back, her face contorted in pain and horror, her voice hoarse from screaming.

"Sarah—*help me*—*please*—" she begs, but her sister only purrs encouragement, holding her hips steady for Alina's final thrust.

Alina bottoms out with a heavy, wet sound, her full length buried to the hilt in Amanda's struggling body, her balls slapping against Amanda's clit. Amanda goes rigid, her breath coming in shallow gasps, her eyes wide and unseeing, overwhelmed by the sheer fullness.

"Please—*it hurts*—*take it out*—" Amanda whimpers, her voice small and broken.

Alina begins to move, establishing a deep, grinding rhythm, her hips rolling in circles that make Amanda gasp and twitch in pain. She pulls back until just the head remains inside, the ridge catching on Amanda's inner walls, then thrusts forward hard, bottoming out with a wet slap.

"No—*no*—" Amanda sobs, but her body is betraying her—the friction building, the pain transforming despite her resistance, her cunt growing wet around the invading shaft.

"That's it," Alina pants, her strokes lengthening, gaining force. "Take it. Take your niece's cock. You came here for a visit, Auntie, and now you're getting fucked. Getting stretched. Getting bred whether you want it or not."

She fucks Amanda with brutal efficiency, her hips snapping hard, each thrust sending her balls slapping against Amanda's clit. Amanda's struggles weaken, transforming despite her will—her hips rising involuntarily, her moans changing from pain to something darker, something she doesn't want to feel.

"Don't—*don't make me*—" Amanda gasps, her back arching deeper, presenting herself more fully despite her sobs. "Oh god—*oh fuck*—"

"Going to make you cum," Alina snarls, angling her thrusts, her cockhead dragging across Amanda's g-spot with every stroke. "Going to make you cum on my Asian cock like the desperate little slut you are, even if you hate it. Cum for me, Auntie. Cum on your niece's dick."

Amanda explodes against her will.

Her orgasm crashes through her like a violation—her back snapping taut, her cunt clamping down on Alina's driving shaft, her scream raw and broken as she convulses around the invading cock. She tries to fight it, shaking her head, denying it even as her body betrays her completely, milking Alina's shaft with rhythmic spasms.

"No—*I didn't want*—*oh god*—" she sobs, but Alina doesn't stop, fucking her through the climax, using her spasming body to chase her own pleasure.

"Again," Alina commands, her fingers finding Amanda's clit, rubbing in tight circles as she continues to pound into her. "Cum again. Right now. Give me another."

"I can't—*please no more*—" Amanda begs, but she comes a second time within minutes—her body jerking involuntarily, her cunt pulsing, another scream tearing from her throat as the pleasure overwhelms her resistance. She collapses forward, but Alina pulls her back up by her hair, forcing her to stay positioned, forcing her to keep taking it.

"One more," Alina demands, her thrusts becoming savage, her cock pistoning in and out of Amanda's stretched, dripping cunt. "Give me one more before I breed you. Cum for me like a good little cheating slut, even while you're crying. Cum knowing you're about to get filled with my bastard seed."

Amanda comes a third time, sobbing, broken, her resistance shattered completely, her cunt clutching at Alina's shaft with rhythmic spasms that draw out the inevitable. She has stopped fighting now—her body limp, accepting, her eyes vacant with overwhelmed submission.

"Hold her," Alina gasps, her hips stuttering, losing rhythm, her balls drawing up tight. "I'm going to cum. Going to fill this cheating cunt with my cum. Going to breed her like the fertile little whore she is."

You and Sarah grip Amanda tighter, pinning her in place as Alina thrusts deep and holds, her cock thickening impossibly, pulsing violently as the first jet floods Amanda's unprotected womb. It's hot, thick, endless—Alina's seed pumping deep into her sister-in-law's fertile cunt, filling her, claiming her, marking her as property despite her whimpers.

"Take it," Alina snarls, her hips jerking with each spurt, her balls contracting as they empty themselves completely into Amanda's unwilling body. "Take my cum, Auntie. Take it in your cheating cunt. Let me breed you. Let me fill you up."

Amanda comes a fourth time as she feels the warm flood filling her, the sensation of being pumped full of seed triggering another violent orgasm that makes her scream and thrash beneath you, her cunt milking Alina's shaft, drawing out every drop, her body finally accepting what her mind fought.

When Alina finally withdraws, her cock slips free with a wet sound, and immediately a thick stream of white cream begins leaking from Amanda's gaping cunt—proof of her complete claiming, her breeding, and her permanent addition to Alina's collection of fucktoys.

"Rest now," Alina breathes, stroking her still-hard cock, smearing the remaining cum across Amanda's trembling thighs. "But only for a little while. You fought too hard, Auntie. I need to break you in properly. Welcome to the family."

Amanda lies panting on the carpet, her cunt leaking her niece's seed, her eyes vacant and broken, and finally, helplessly hungry for more, while you and Sarah hold her, keeping her warm, keeping her ready for round two.

To be continued.
