Chapter 1 She Could Not Believe Her Eyes

"Fuck yes, Amber... take it like that... just like your sister never could..." "Mia stepped into her house, the door creaking quietly behind her, but the moans?

The obscene, sloppy, skin-slapping sounds? They hit her like a bullet to the chest. She froze. No. No, this couldn't be real. But then she heard it.

"Ohhh! fuck, Nathan! Stretch this tight little pussy out! Fuck me like the dirty bitch I am!" Mia's heart stopped. That voice. Amber's voice.

She crept forward on trembling legs, eyes wide, her acceptance letter still clenched in her hand, dreams burning to ash before they ever had the chance to bloom.

And there it was. Her couch. Amber, naked, back arched, face buried in the cushions. Her ass up, red and bouncing with every brutal thrust Nathan slammed into her from behind.

Sweat slicked their bodies, their skin sticky and glistening like porn stars mid-scene. And Nathan? He was grinning. Groaning. Holding her sister's hips like she was his.

"Fuck, baby... this pussy was made to be used. You like that? Huh? You like your big sister's man fucking you this deep?" His hand tangled in Amber's hair, yanking her head back.

"Tell me how much tighter you are." Amber moaned, loud. Shameless. "I'm so much tighter than her! Fuck me, Nathan! She doesn't deserve your cock! I want it! All of it!" Mia's breath hitched.

Her knees nearly gave out. Nathan leaned down, grinding into her sister, balls slapping against her soaked cunt. "Mia was so fucking boring. Starfish bitch. Just laid there. But you, fuck, you clench around me like a fucking virgin. Your sister could never take me like this." "Then ruin me!" Amber screamed, clawing at the couch, ass jerking back against him.

"Breed me, Nathan! Fill me up with your cum! I want your babies, not hers, fuck, just like that!" Mia dropped her letter.

The paper fluttered to the floor in silence as her world collapsed.The moans. The grunts. The wet fucking sounds. It was all real. Her little sister was creaming all over the cock that had been inside her just days ago.

She felt sick as she watched Nathan slammed into Amber harder, panting, his voice dark and vicious. "You're so fucking nasty. My filthy little slut. Your sister was nothing but a warm hole! but you? You were born to be fucked. Over and over. Fuck, I'm close, take this cock, Amber!"

"Yes!" Amber shrieked, biting her lip. "Cum in me! Fucking cum in me like you'd never dare cum in her!" Mia couldn't move. This was her blood. Her man. Her couch.

And they were ripping her apart, together, like she never mattered at all. She watched them in sobs. As her sisters moans were echoing off the fucking walls. High-pitched, breathless, like she lived for his cock.

Her fingers were clawing at the cushions, face buried in the same pillow Mia cried into just last week. Her ass was red from spanking, glistening from her own arousal, jiggling violently every time Nathan rammed into her. "Fuck, baby," Nathan groaned, slamming into her like a beast, his hands gripping her hips so tight his knuckles turned white.

"I'm gonna cum. Do you want it? Huh? Want my fucking load, you nasty little slut?" "Yes! Cum in me! Fuck, I want it all! give it to me, Nathan, breed my fucking pussy!" Mia stood there, frozen in the doorway, her nails digging into her palms so hard they could've drawn blood. But they didn't hear her.

They were too far gone. Nathan was pounding her sister like she was a cumdump, his balls slapping, his voice dark and wicked as his thrusts grew faster. "Mia never let me cum in her... but you? You're begging for it. Dirty. Fucking. Whore." Amber was screaming now, voice cracked and raw, her body trembling beneath him.

"I'm cumming! Fuck! Nathan! cum with me! please! Fill me up, make me yours! ahhh!" Nathan grunted like an animal, and with one last deep, brutal thrust, he slammed his cock into her and let go.

"Fuck! take it! Take my fucking cum, Amber!" Mia watched in horror as her sister's body arched, her toes curled, and Nathan collapsed over her, still buried deep, pulsing inside her. And then.

"WHAT THE FUCK?!" Her scream ripped through the air like a thunderclap. Amber gasped. Nathan froze. Their heads whipped toward the doorway in unison. Mia was standing there, shaking. Broken. Eyes wild. Chest heaving.

Her heart was in pieces, and she was watching the two people she trusted most, covered in sweat and cum, still tangled together like she was the intruder in her own fucking home. Amber's mouth dropped open.

Nathan looked like he'd seen a ghost. Mia's voice came again, louder this time. Raw. Furious. Devastated. "On my fucking couch?! My baby sister?! You were supposed to love me!" They didn't move. They couldn't.

Nathan's cock was still half-hard, glistening with her sister's cum when Mia stepped closer. Amber didn't even flinch. That smug little whore just sat there, naked and stretched out, cum dripping from between her thighs, lips parted like she enjoyed being caught.

Then she said it, that line. "He loves my pussy more than yours, bitch." She even fucking giggled afterward, like this was a game. Mia's body shook. Her nails dug into her palms. But her face? Cold. Emotionless.

A storm brewing behind her eyes. She clicked her tongue slowly, cocked her head, and smiled, just once. "Cute," she whispered. "Now get the fuck out of my house." Nathan's eyes widened. Amber blinked. But Mia was already moving.

She stormed across the room, grabbing every piece of clothing she could find, his shirt, her bra, his belt, her thong soaked in cum, and threw it at them, piece by piece, like it was trash. "Out," she snapped. "Now." Nathan started to reach for her. "Mia, baby, please!" "Don't fucking call me that!" she exploded.

"You were just balls-deep in my baby sister! You're lucky I didn't slice that pathetic dick off and feed it to the rats!" Amber stood slowly, no shame on her naked body.

"He didn't even moan your name, sis," she said with a smirk. "I guess I just fuck better." Mia's mouth twisted in disgust. "You're eighteen and already a certified slut. Congratulations. Your diploma's dripping out of your pussy." She opened the front door and stepped aside.

Nathan grabbed his jeans and tried to cover himself. Amber strutted out completely naked, tits bouncing, cum trailing down her thighs like a trophy. Mia didn't blink.

She grabbed Amber by the hair and shoved her through the door, hard. "Both of you," she snarled. "Get the fuck out of my house." Nathan turned with one last pathetic look.

"Mia, please, I didn't mean..." She slammed the door wide open again and hurled his boxers at his face. "You meant every word when you were balls-deep in her, right? When you were moaning how tight her teenage pussy was?"

"You're fucking dead to me." Then, with her heart in splinters and rage bubbling in her throat, she raised her middle finger high. "Enjoy hell, you backstabbing cum-sluts." SLAM.

The door slammed so hard the walls shook. And Mia? She slid down against it, breath shuddering, fists clenched, tears falling hot and silent. They fucked her life apart.
