Almost caught in the act

My heart slammed against my ribs as Derek drove into me from behind, his thick cock stretching my sore pussy with every brutal thrust.

 The couch creaked softly under my weight. I bit down hard on my forearm to keep from moaning, but it was almost impossible. He felt too good…too deep and too possessive.

“Fuck, you’re clenching so tight,” he growled low in my ear, one hand fisted in my hair while the other gripped my hip hard enough to leave marks.

“Afraid Mommy will hear how much you love Daddy’s cock?”

I could only whimper in response. The shower had stopped and I could here footstep moving downstairs. Every second brought Mom closer to coming down, yet Derek didn’t slow down. If anything, he fucked me harder, his heavy balls slapping against my clit with wet, filthy sounds that seemed deafening in the quiet house.

I was bent over the back of the couch like a whore, white sundress bunched around my waist, ass up and completely exposed. My nipples scraped against the fabric with every thrust. My thighs trembled violently.

“Derek… please…” I gasped, barely a whisper.

“Please what?” He reached around and rubbed my swollen clit in fast, merciless circles. 

“Please make you cum? Or please don’t stop even if she walks in?”

I hated how much it turned me on. This was wrong, so fucking wrong. My own mother was upstairs, and here I was letting my stepdad ruin me in the living room.

His cock hit that perfect spot again and again. My eyes rolled back. I was so close… teetering right on the edge.

“Oh god—” I choked.

Derek clamped his large hand over my mouth, muffling my cry as he pounded into me relentlessly. The angle let him go impossibly deep. I came hard, my pussy spasming and gushing around his thick shaft. My whole body shook with the force of it, but his hand kept every sound trapped.

“Good girl,” he rasped, voice dark with satisfaction. 

“Cum on Daddy’s cock while your mother comes down the stairs.”

He didn’t stop. He kept fucking me through my orgasm, chasing his own. The footsteps reached the bottom of the stairs and paused. I heard Mom humming softly to herself.

Derek’s thrusts became shorter, deeper, more aggressive.

“Gonna fill this tight little pussy,” he whispered against my ear, breath hot. 

“You’re going to walk around with my cum dripping down your thighs while you smile at Mommy.”

I shook my head frantically, but my body betrayed me another smaller orgasm rippled through me at his filthy words. Derek groaned quietly, buried himself to the hilt, and came.

His cock pulsed hard inside me, flooding my pussy with thick, hot spurts of cum. He held me there, pinned and full, grinding slowly as he emptied every drop. I felt so dirty.

The humming grew closer and at the last possible second, Derek pulled out. A thick trickle of his cum immediately started leaking down my inner thigh. He quickly yanked my sundress back down over my ass, smoothing it roughly.

I barely had time to straighten up before Mom walked into the living room.

She looked refreshed, hair damp, wearing comfortable loungewear. 

“There you two are. I was thinking we could—”

Her eyes landed on me. I must have looked wrecked…. flushed cheeks, messy hair, trembling legs. Derek stood a few feet away, casually adjusting his shirt, the picture of calm control.

“Sweetheart, are you okay?” Mom asked, frowning slightly. 

“You look a little feverish.”

“I’m fine,” I croaked, forcing a smile. My pussy was still throbbing, leaking Derek’s cum into the fabric of my sundress. I pressed my thighs together desperately, trying to stop it from running further down my leg.

Derek stepped forward and wrapped an arm around my shoulders, pulling me against his side like the perfect, caring stepfather. His fingers brushed the back of my neck, right over one of the marks he’d left last night.

“She probably didn’t sleep well,” he said smoothly. 

“I kept her up late talking.”

The double meaning made my stomach flip. I could feel his cum slowly sliding down my thigh. If Mom looked down…

“I was thinking we could all do something together today,” Mom continued brightly, completely unaware. 

“Maybe go for a walk or watch a movie. It’s been so long since we had family time.”

Family time…The words made me want to laugh and cry at the same time.

Derek’s hand slid lower, resting possessively on my hip. 

“Sounds perfect. Why don’t you go make us some coffee, princess? I’ll help your mom unpack.”

I nodded quickly, grateful for the excuse to escape. As I walked toward the kitchen, I felt every step. Cum continued to leak out of me, making my inner thighs slick. I moved carefully, terrified it would drip onto the floor.

In the kitchen, I gripped the counter, trying to catch my breath. My mind was spinning. What the hell was I doing? This had to stop. It was too dangerous. But even as I thought it, my pussy clenched at the memory of Derek’s cock filling me while Mom was just upstairs.

I heard them talking in low voices in the living room then footsteps. Derek appeared in the kitchen doorway alone.

His eyes darkened when he saw me. Without a word, he crossed the room, spun me around, and bent me over the kitchen counter. I gasped.

“Derek—”

“Shh.” He flipped my sundress up again and pushed two fingers into my cum-filled pussy. 

“I wanted to make sure you’re still full of me.”

I moaned softly, pushing back against his hand despite myself. He finger-fucked me slowly, stirring his own load inside me.

“You’re going to keep my cum inside you all day,” he murmured darkly. 

“Every time you look at your mother, you’ll remember who you really belong to.”

I heard footsteps approached again.

He pulled his fingers out and licked them clean just as Mom entered the kitchen. I turned around quickly, heart racing.

“Everything alright in here?” she asked.

“Perfect,” Derek answered, voice warm. He smiled at her, then looked at me with pure possession burning in his eyes. 

“We’re all going to have a wonderful day together.”

I swallowed hard, feeling another trickle of his cum slip down my leg.

Later that afternoon, the three of us sat in the living room watching a movie. I was curled up on the couch between them …. Mom on my left, Derek on my right. The same couch he’d fucked me on hours earlier.

Mom was engrossed in the film, but Derek’s hand had found its way under the blanket covering my lap. His fingers teased my bare pussy lazily, occasionally dipping inside to play with the mess he’d left earlier.

I bit my lip until it hurt, fighting to keep my breathing steady. Every slow circle of his thumb on my clit made me want to moan.

Halfway through the movie, Derek leaned over and whispered so quietly only I could hear

“Don’t moan out darling, or do you want mommy to find out about your dirty little secret?”
