C5 Bred And Blackmailed by My Stepbrother

LENA'S POV

Marcus had me pinned naked against his locked bedroom door before I could even catch my breath from Mom’s call. My back pressed to the wood, legs wrapped tight around his waist as he thrust deep and slow into my dripping pussy. Downstairs, voices drifted up—MOM laughing with Alex, Dad asking about dinner. The risk made everything sharper.

“One last creampie before we face them, baby,” Marcus growled low against my neck, his thick cock dragging along my walls with every deliberate roll of his hips. “Let your stepbrother fill you while they wait downstairs.”

I bit my lip hard, nails digging into his shoulders. “You’re insane. They’re right there—”

He cut me off with a deeper thrust, grinding his pelvis against my clit. My pussy clenched around him, milking his length as fresh slick mixed with the cum still leaking from last night. He felt huge like this, every vein and ridge rubbing me perfectly. I whimpered, forehead dropping to his shoulder.

“Shh. I’ve got you.” His voice stayed steady even as he fucked me slow and filthy. One hand gripped my ass, spreading me wider so he could sink even deeper. The wet squelch of my creamy pussy taking him echoed softly with each push. “This cunt is mine. Always has been.”

I rocked my hips to meet him, hating how desperate I felt. My tits pressed against his chest, nipples hard and sensitive. He dipped his head and sucked one into his mouth, tongue flicking the peak while he kept that maddening rhythm—pulling out until just the fat head stretched my entrance, then sliding back in until his balls nestled against me.

“Marcus… fuck…” My breath hitched. Pressure built fast, coiling low in my belly. I was already so full from before, but he kept stirring everything, pushing his cum deeper, making room for more.

He released my nipple with a wet pop and looked me dead in the eyes. “Cum for me first. Want to feel you fall apart before we go down there.”

His hand slipped between us. Two fingers rubbed tight circles on my swollen clit while he fucked me with those long, grinding strokes. My thighs started shaking. I buried my face in his neck to muffle my moans as the orgasm ripped through me. My pussy spasmed hard around his cock, gushing down his length, soaking his balls.

“That’s my good girl,” he praised, voice rough. He didn’t stop. He fucked me through it, faster now, hips snapping. “Gonna breed you one more time. Put my baby so deep no one can take you from me.”

I came again just from his words, whimpering his name. Marcus groaned, buried himself to the hilt, and let go. Thick, hot jets of cum flooded my womb. Pulse after pulse until it overflowed, running down my ass and thighs in messy streams. He held me there, still inside, kissing my forehead, my cheeks, my lips—soft and reverent while his cock twitched with the last spurts.

We stayed locked like that for a long minute, breathing each other in. Then he gently lowered my legs and cleaned me with a warm cloth, wiping between my folds with careful strokes even as more cum tried to leak out. He kissed my belly softly before helping me dress.

“Ready?” he asked, thumb brushing my jaw.

“No. But we have to.”

Downstairs was worse than I imagined.

Mom hugged me tight, then pulled back with worried eyes. “Alex told us things seem tense. Honey, is Marcus giving you trouble again?”

Alex stood by the couch, arms crossed, smirking like he’d already won. Dad looked between all of us, confused.

Marcus stepped up beside me, hand resting possessively on my lower back. “There’s no trouble. Lena’s exactly where she belongs.”

Alex laughed coldly. “Belongs? You’ve been blackmailing her with those videos. I saw the folder. I have copies now. Pay up or I send everything to your parents and her college.”

The room went dead silent.

Marcus’s hand tightened on me, but his voice stayed calm. “You really want to play this, kid? I deleted every file this morning. Publicly. Wiped the cloud. Sent proof to Lena’s email.” He pulled out his phone and showed the screen—confirmation emails, timestamps. “I’m done using her past against her. Unlike you.”

I stared at him. My chest tightened. He actually did it. Destroyed the leverage that started all of this.

“You what?” I whispered.

Marcus looked at me, eyes soft in a way that made my knees weak. “I love you, Lena. Not the control. Not the games. You. The fire, the fight, the way you make me want to be better. I’m not losing you to threats.”

Tears stung my eyes. I grabbed his hand. “I hate what you did… but I love you too. This twisted, protective mess. All of it.”

Alex’s face twisted. “You’re choosing him? After he—”

“After he protected me when I was too reckless to protect myself,” I snapped. “We’re done, Alex. The engagement’s off.”

Mom gasped. Dad started asking questions. Chaos erupted—accusations flying, Alex threatening to go public anyway, Mom trying to calm everyone. Marcus handled it like the ruthless businessman he was. Calm threats about Alex’s own scandals. Offers to buy him out of any story he tried to sell. In the end Alex stormed out, defeated but still spitting warnings.

By the time the dust settled, my parents agreed to give us space. They went upstairs to unpack, muttering about “figuring things out.”

Marcus pulled me straight back to his room, locked the door, and stripped me naked again in seconds. We didn’t even make it to the bed. He bent me over the desk this time, much like the first day, but different now. No hate. Just raw need.

He spread my legs and licked me first—long, hungry strokes of his tongue through my folds, sucking our combined mess from my pussy while I moaned and pushed back against his face. Then he stood and slammed into me from behind.

“Fuck, Lena,” he groaned, hips slapping my ass. “Love how you take me. So fucking perfect.”

He fucked me hard but loving—deep thrusts that made my tits bounce against the wood, one hand reaching around to rub my clit, the other gripping my hip. I came twice like that, shaking and crying out his name. He pulled out, flipped me onto my back on the desk, and pushed back in missionary style. Eye contact the whole time. Forehead to forehead.

“I’m keeping you,” he whispered between thrusts. “Forever. My wife. My everything.”

“Fill me,” I begged, legs locked around him. “Breed me, Marcus.”

He did. He came with a deep groan, pumping me full again until cum squirted out around his cock with every thrust. We stayed connected, kissing slow and deep, bodies slick with sweat.

After, he carried me to the bed, still naked, and laid me down gently. He kissed down my body, lingering on my belly, pressing soft kisses there like a promise.

I reached for the pregnancy test I’d hidden in my drawer and handed it to him, heart pounding.

Two pink lines. Clear as day.

Marcus’s eyes widened. Then a slow, possessive smile spread across his face. He kissed my belly again, reverent this time, hand splaying over it.

“Our baby,” he murmured. “Forbidden. Real. Mine.”

Tears slipped down my cheeks. Happiness. Fear. Everything tangled together. “They’re still suspicious downstairs. Alex might come back. Mom and Dad… how long until this explodes?”

He pulled me into his arms, naked bodies tangled, his hand never leaving my belly. “We’ll face it. Together. But right now, you’re full of my cum and carrying my kid. That’s all that matters.”

My phone buzzed on the nightstand. A text from an unknown number.

*Nice try deleting the files. I kept backups. Send money or the world sees everything tomorrow.*

Marcus read it over my shoulder. His body tensed against mine.

The secret was growing inside me, but the threats outside weren’t done. And with my parents just down the hall, one wrong sound could blow our entire forbidden world apart.
