PART 3: Seducing My Stepbrother

SEDUCING MY STEPBROTHER

Chapter 3: Fuck look at you

Sunlight filtered through the blinds in thin golden stripes across my bed, but I barely noticed.

My body still hummed from last night — Alex's tongue between my thighs, his fingers stretching me, the way he'd held me after like I was something precious and filthy all at once.

I'd woken up alone, sheets tangled, a faint ache between my legs that only made me want more.

I shouldn't want more.

But I did.

The house was still quiet. Parents wouldn't be back until tomorrow night. Plenty of time to pretend this wasn't happening. Or... to make it happen again.

I showered fast, scrubbing away the evidence of last night's sins, but the hot water only made me think of his mouth. His hands. The way he'd growled "you're mine this weekend" like it was law.

Wrapped in just a towel, I padded down the hall. His door was closed this time. I hesitated, heart thudding.

Then I knocked. Soft. Tentative.

It swung open almost immediately.

Alex stood there in low-slung gray sweatpants, no shirt, hair messy from sleep.

His eyes darkened the second he saw me — towel clinging to damp skin, droplets trailing down my cleavage.

"Mia." Voice rough, like gravel. "You came back."

I swallowed. "I... just couldn't stay away."

He didn't smile. Just stepped aside, letting me in, then shut the door with a click that sounded final.

The room smelled like him and suddenly my towel felt too thin.

He backed me against the door, not touching yet. Towering. "Tell me why you're here."

I lifted my chin. "You know why."

"Say it." His hand came up, fingers tracing the edge of the towel over my collarbone. Slow. Teasing. "Use your words, little sis."

Heat flooded my face — and lower. "I want you to fuck me, Alex."

His eyes flashed. "Good girl."

Then he yanked the towel away in one swift pull. It pooled at my feet. Naked. Exposed. Nipples hardening under his stare.

He drank me in like I was his last meal. "Fuck. Look at you." Hand cupped my breast, thumb circling the peak until I whimpered.

"Been hard since I woke up thinking about burying myself in this tight little body."

He kissed me then — brutal, claiming. Tongue deep, teeth nipping my lip. I moaned into his mouth, hands scrambling over his shoulders, nails digging in.

He lifted me easily, legs wrapping around his waist as he carried me to the bed.

Dropped me on my back, following down, pinning my wrists above my head with one big hand.

"Keep them there," he ordered. "Don't move."

I nodded, breathless.

He kissed down my neck, sucking hard enough to bruise — marks I'd have to cover later. But right now? I wanted them. Wanted proof this was real.

Lower. Teeth grazing my nipple, then sucking hard. I arched, crying out. His free hand slid between my thighs, finding me already slick.

"So fucking wet." Two fingers plunged in without warning, curling. "This pussy's been dripping for your stepbrother all morning, hasn't it?"

"Yes," I gasped. "Alex— please—"

He pumped faster, thumb on my clit. "Please what? Beg properly."

"Please fuck me. I need your cock inside me."

He groaned, low and feral. Withdrew his fingers, licked them clean while staring down at me. Then shoved his sweatpants down.

His cock sprang free — thick, veined, flushed dark at the tip, pre-cum beading. Bigger than I'd imagined. My mouth watered.

"Not yet." He flipped me onto my stomach, yanking my hips up. Ass in the air. "First I want to see this pretty pussy take me."

He rubbed the head through my folds, teasing my entrance. I pushed back, desperate.

"Patience." A sharp slap to my ass — stinging, hot. I yelped, but the burn turned to throbbing need. "You take what I give you."

Another slap. Harder. I moaned, pushing back again.

"Fuck, you like that." He soothed the red mark with his palm, then lined up. "Gonna claim this cunt now, Mia. Make it mine. No one else gets this. Ever."

The head pushed in — slow at first, stretching me. I whimpered at the fullness.

"Breathe, baby." He sank deeper, inch by inch. "So tight. Fucking perfect."

When he bottomed out, hips flush against my ass, we both groaned.

He stayed still a second, letting me adjust. Then pulled back almost all the way... and slammed back in.

Hard.

I cried out, fists clenching the sheets.

"That's it." He set a brutal pace — deep, punishing thrusts that hit every sensitive spot. "Take it. Take your stepbrother's cock like the good little slut you are."

The words should have shocked me. Instead, they made me clench around him.

He felt it. Growled. "You love the dirty talk, don't you? Love hearing how wrong this is while I fuck you raw."

"Yes— oh Gosh— harder—"

He obliged. One hand fisted my hair, yanking my head back so he could see my face. The angle changed — deeper, hitting that spot over and over.

"Gonna fill you up," he rasped. "Gonna come so deep inside this forbidden pussy you'll feel me leaking out for days. Mark you from the inside."

The thought sent me spiraling. I rocked back, meeting every thrust. "Do it. Please— claim me—"

His other hand slid around, fingers finding my clit. Rubbing fast circles.

"Come for me first. Milk my cock. Show me how bad you need your stepbrother's cum."

The command tipped me over. Orgasm crashed through me — violent, blinding. I screamed his name, walls fluttering, squeezing him tight.

He didn't stop. Fucked me through it, harder, chasing his own release.

"Fuck— Mia—"

One last deep thrust. He buried himself to the hilt, groaning my name as he came. Hot pulses filling me, spilling deep. Claiming.

We collapsed together, breathing ragged. He stayed inside me, softening slowly, arms wrapping around like he never wanted to let go.

After a minute, he kissed my shoulder. Soft now. "You okay?"

I nodded, dazed. "More than okay."

He pulled out carefully, cum trickling down my thigh. The sight made him growl again. "Look at that. My cum in you. Where it belongs."

He flipped me over, spreading my legs. Watched it drip. Then leaned down, tongue lapping at the mess — tasting us together.

I whimpered, oversensitive. "Alex—"

"Just cleaning you up." But his eyes were dark again. Hungry. "Or maybe getting you ready for round two."

He crawled up, cock already hardening against my thigh.

"Already?" I breathed.

He smirked. "Told you. This weekend you're mine. All of you."

He slid back in — slow this time, missionary, eyes locked on mine.

"Feel that?" he whispered, rolling his hips. "That's me owning you. Every inch."

I wrapped my legs around him, pulling him deeper. "Then own me, daddy. Don't stop."

He didn't.

We went again — slower, deeper, more intense eye contact. Dirty whispers in my ear: "You're addicted now. Can't go back." Another orgasm ripped through me, his following right after, filling me again.

By the time we finished, bodies slick with sweat, I was boneless. Marked. Claimed.

He held me close, fingers tracing the bruises on my neck. "No regrets?"

I shook my head. "None."

But deep down, a tiny voice whispered: What happens when the weekend ends?

He kissed my forehead. "Good. Because I'm not done with you yet."

The door downstairs creaked — distant, maybe nothing.

Or maybe not.

We froze.

Parents home early?
