Stepbrother's Filthy Secret

🍆Chapter 1🍆

My back hit against the hallway wall so hard a picture frame fell beside my head. Ryan’s big hand gripped my mouth tightly before I could even gasp. His eyes were wild, dark with that dangerous hunger I knew too well. His other hand was already pulling my loose shorts down my thighs, fingers rough as they shoved between my legs.

“Quiet,” he muttered darkly against my ear, breath burning my skin. “They’re right downstairs. You want Mom to hear how wet your pussy gets for your stepbrother?”

I shook my head fast, heart pounding like a drum in my chest. But my body was a traitor. My thighs parted wider on their own as two of his thick fingers pushed deep inside me without any gentleness. I was soaked, embarrassingly wet, and the wet sound as he pumped them in and out made my face burn with shame and excitement.

This was crazy and completely insane.

Our parents had come back early from their fancy anniversary dinner. We heard the front door open when Ryan already had me bent over the couch downstairs. We barely made it up here before their faint voices echoed up from the living room, talking and laughing like normal.

Now here I was, pinned against the wall in the upstairs hallway, shorts around my ankles, stepbrother’s fingers buried deep inside my dripping cunt while our parents were just one floor below.

Ryan pulled his fingers out suddenly, turned me around like I weighed nothing, and bent me over the narrow decorative table against the wall. My breasts pressed hard against the cold wood through my thin tank top. My nipples were hard as rock, aching. I heard his zipper go down, then the heavy, thick sound of his hard cock slapping against my bare ass.

“Ryan… please…” I whispered, voice shaking.

“Please what?” he breathed, rubbing the fat head of his cock up and down my slippery pussy. 

“Please stop? Or please fuck you harder than last time?”

Before I could answer, he thrust forward. One long, powerful stroke and he buried every inch inside me. I bit my lip until it hurt, fighting back the loud moan that wanted to escape out of my throat. He was so big, stretching me open, filling me completely. The sudden fullness made my eyes water and my toes curl.

He didn’t wait. He started pounding me right there, hips slapping against my ass with every thrust. The table creaked under me. My juices were running down my thighs. The wet, filthy sounds of him fucking me echoed way too loud in the quiet hallway.

“Fuck, Sophie,” he moaned quietly, gripping my hips hard enough to leave marks. “This tight little pussy always sucks me in like it missed me. You were made for my cock. My dirty little stepsister.”

I gripped the edges of the table, knuckles turning white. Every deep stroke hit that perfect spot inside me, sending waves of pleasure shooting up my spine. I hated how good it felt. I hated how much I needed this. We swore after the first time last summer that it would never happen again. We are a family now. It was wrong and forbidden.

But the moment we were alone in the house tonight, all it took was one look and we were all over each other like animals.

Ryan reached around and found my swollen clit. His fingers rubbed it in fast, tight circles while he kept fucking me from behind. My legs started shaking. I was close already, embarrassingly close.

Downstairs, Mom’s laugh sounded out clearly, followed by my stepdad’s deep voice saying something about the movie they watched. They sounded so normal.

The risk made everything hotter. My pussy tightened hard around Ryan’s thick cock.

“That’s it,” he whispered, voice rough. “Cum on your stepbrother’s dick while they’re right downstairs. Be a good girl and lower your voice.”

I couldn’t stay quiet. The orgasm crashed into me like a wave. My whole body tensed up, walls aching and tightening around him as pleasure ripped through me. A broken moan escaped against his hand. Ryan quickly pressed his palm tighter over my mouth, muffling the sound while he fucked me through it, harder, faster, chasing his own release.

“Such a naughty fucking slut,” he hissed in my ear. “Gonna fill this pussy up. Pump you full until it’s dripping down your legs. Maybe I’ll breed you right here. Put a baby in my stepsister while Mom and Dad are watching TV.”

The dirty words sent another forbidden rush through me. My pussy tingled again. I shouldn’t have loved it when he talked like that. But God, I did. The thought of him cumming deep inside me, risking everything, made me dizzy with lust.

His thrusts became wild, deeper, more desperate. I felt his cock get even bigger inside me. He was right there on the edge.

Then we both froze.

Footsteps on the stairs.

“Sophie? Ryan? Are you two home?” Mom’s voice, cheerful, getting closer with every step.

My heart nearly exploded. Ryan was still buried deep inside me, his cock throbbing, leaking pre-cum into my pussy. He didn’t pull out. Instead, he pressed me harder down against the table, one hand still covering my mouth, the other gripping my hip possessively.

He slowly rolled his hips, grinding his cock against my sensitive walls, teasing me, torturing me. Keeping me right on the edge even as terror flooded my veins.

“Answer her,” he whispered, voice dark and commanding.

I swallowed hard, trying to steady my breathing. My voice came out shaky. “Y-yeah, Mom! We’re upstairs… just… watching something.”

Ryan chose that exact second to give one small, dirty thrust. His cock pressed against my g-spot perfectly. My eyes rolled back and I had to bite my tongue to stop from moaning.

“Okay, sweetie! We brought cake from that fancy place you like!” Mom called back. Her footsteps paused on the landing, only a few steps away from the hallway where her son was buried inside her daughter.

Ryan’s breath was hot and ragged against the back of my neck. He kept grinding slowly, his thick cock moving in tiny circles inside me, rubbing every sensitive part. His free hand slid down again and started playing with my clit, slow and mean, forcing me toward another orgasm while my mom stood so close.

I was going to cum again. With my stepbrother’s dick inside me and my mother less than fifteen feet away.

This was our filthy secret. The one we swore we’d bury forever.

But right now, with Ryan’s cock ramming deep in my pussy and the terrifying thrill of getting caught making my blood run hot, I didn’t want to stop. I wanted him to fuck me harder and roughly. I wanted him to fill me up. I wanted everything.

The footsteps started moving again, but this time toward the kitchen instead of coming down the hall. We had a small window.

Ryan pulled his hand off my mouth just enough to let me breathe. “You’re mine, Sophie,” he growled quietly. “This pussy is mine. Say it.”

“I’m yours,” I whispered, voice trembling with need and fear and pure lust.

He pulled back slowly until just the head of his cock was inside me, then slammed back in hard. The table shook. I had to cover my own mouth this time.

We were playing with fire. And neither of us wanted to put it out.
