C3 Stretching My Sister’s Pussy- 3

LENA’S POV

The silence after Alex stormed out was deafening.

I sat on the edge of the guest bed, legs trembling, Marcus’s thick cum still leaking out of my ruined pussy in slow, warm trails down my inner thighs. My engagement ring felt like it was burning a hole in my finger. Everything I had built, my relationship, my reputation, my future was crumbling because I couldn’t stop letting my own stepbrother fuck me raw.

Marcus stood in the doorway, shirt open, cock still half-hard and glistening with our mess. His eyes were dark, victorious, and hungry.

“You ruined everything,” I whispered, tears spilling down my cheeks. “Alex knows. He’s probably telling everyone right now.”

Marcus crossed the room slowly and knelt in front of me. For once, there was no smirk. Just raw hunger and something almost like regret.

“I didn’t ruin you,” he said quietly. “You were already mine. You’ve been mine since the day our parents married. Alex was just a distraction.”

I laughed bitterly, but it came out as a sob. “I was supposed to marry him. Have a normal life. Not be my stepbrother’s secret cumslut.”

Marcus cupped my face, thumbs wiping my tears. “Then choose. Go chase after that pathetic boy… or stay. Let me give you what he never could.”

His hand slid between my legs, fingers pushing through the mess he’d left inside me. I whimpered, hating how my body responded instantly.

“Choose, Lena,” he whispered, curling his fingers deep. “Stay and I’ll fuck you every night. Breed you. Make you mine completely. Or leave… and I’ll delete every video. You’ll never hear from me again.”

The choice hung between us like a blade.

I looked at him, my arrogant, possessive, dangerously addictive stepbrother and felt everything crash over me. The shame. The lust. The terrifying love I’d been trying to deny for years.

I grabbed his shirt and pulled him down on top of me.

“Stay,” I whispered against his lips. “Fuck me. Ruin me. I don’t care anymore.”

Marcus groaned and thrust into me in one hard stroke, burying himself to the hilt. I cried out, wrapping my legs around him as he fucked me deep and desperate on the same bed where Alex had slept just hours ago.

“This pussy is mine,” he growled, pounding into me. “Say it.”

“It’s yours,” I moaned, nails raking down his back. “I’m yours, Marcus. Only yours.”

He fucked me like a man who had finally won. Hard. Deep. Possessive. The bed slammed against the wall as he claimed me completely, filling me with another thick load of cum while I came around him, sobbing his name.

Afterward, he held me close, stroking my hair as I cried against his chest.

“You made the right choice,” he murmured. “I’ll take care of you. Always.”

But as I lay there in his arms, his cum still leaking out of me, my phone buzzed again.

A message from my mother.

What is this video? Lena, call me right now.

Marcus read it over my shoulder and laughed darkly, his cock twitching inside me again.

“Looks like the whole family knows their perfect daughter is my personal breeding slut now.”

He started fucking me again, slow and deep, while my phone kept buzzing with notifications.

“Welcome to the rest of your life, sis. No more hiding. Everyone’s going to know exactly who you belong to.”

I moaned helplessly, legs wrapped around him as he claimed me again, my reputation in ruins, my future destroyed.

And the worst part? I was already addicted. I never wanted it to stop.

As Marcus bred me one last time that night, my phone lit up with a new message from an unknown number.

You think your stepbrother is dangerous? Wait until you meet your new stepfather… and the man who’s going to claim you on your mother’s wedding night.

Marcus read it and laughed darkly, pushing his cock deeper.

“Looks like the real fun is just beginning, Lena.”
