Caught By My Step Dad Moaning My Name 5

~Nastya

He didn't need to be told twice. With a low, animalistic grunt, George surged forward, burying his thick head straight into my tight, soaking heat.

The stretch was so immediate and intense it ripped a sharp, breathless scream right out of my throat.

My eyes rolled back as my fingers strained uselessly against the leather straps binding my wrists. It felt like he was splitting me wide open, filling every inch of space inside me.

"Ah… fuck! George!" I gasped, my hips instinctively trying to pull back, but his massive hands locked around my waist, pinning me flat against the smooth wood of his desk.

He stayed completely still for a second, letting me adjust to the sheer size of him buried deep inside me. His heavy breathing filled the room, his hot sweat dripping down onto my chest as his dark eyes locked onto mine with terrifying possession.

"I told you," he growled, his voice a deep, gravelly vibration that sent a shudder straight to my core. "You asked for this, Nastya."

Without waiting another second, he pulled back until only the tip remained, and then slammed all the way home.

A loud, wet slap echoed through the study as his hips cracked against my ass. My toes curled tight, a high pitched moan tearing from my lips as the sharp pain instantly dissolved into pure, white-hot pleasure.

One thrust. Two. Three.

By the fifth relentless drive, my body adapted completely, wrapping around his thick shaft like a glove. The friction was unbearable, every stroke hitting a deep, sensitive spot that made my vision blur.

"Yes! Right there! Fuck, Daddy, don't stop!" I cried out, my head thrashing against the mahogany.

George went wild. He picked up a brutal, rhythmic pace, pounding into me with pure, unbridled force.

The heavy desk scraped loudly against the floorboards with every violent hit. He didn't hold back, using his full weight and strength to drive himself deeper and deeper, his calloused thumbs digging into my hips, leaving red marks that would stay for days.

The sound of our bodies colliding filled the air, mixed with his ragged grunts and my helpless, continuous screams.

"Look at you," he panted, his mouth coming down to bite down softly on my neck as he kept up the frantic pace. "Taking all of me... like you were made for it."

"I am... I'm yours, George!" I sobbed out, completely overwhelmed.

The heat in my belly coiled so tight it became unbearable. I was hovering right on the edge, my walls tightening around his cock like a vise, milking him with every thrust.

Feeling how tight I was squeezing him, George snapped, his thrusts turning fast, short, and ruthless.

"I'm coming, Nastya," he roared, leaning down to press a deep, bruising kiss onto my lips. "Take it!"

The force of his climax triggered mine. A violent, body racking orgasm crashed over me, making my inner muscles contract frantically around him.

George let out a deafening groan, thrusting one final time to seed himself as deep as possible as he flooded my warm center.

We both lay there breathless, chest to chest, the leather straps still holding my wrists above my head as his weight rested heavily on top of me.

He slowly unbuckled my wrists, pulling me up into his arms while he was still buried inside me, his lips brushing against my temple.

"Make sure the whole house knows," he whispered, a dark, satisfied smirk resting on his lips as he gave one last, lazy nudge inside me.

I couldn't even reply. My body was completely spent, every muscle trembling as he slowly slid out of me.

A warm, slick trickle immediately ran down the inside of my thigh, leaving an undeniable mark of what we had just done right on the leather chair of his mahogany desk.

George stood up, completely unbothered by his nakedness, and calmly adjusted his trousers.

He looked down at me, taking in my disheveled hair, my swollen lips, and the sheer exhaustion painted across my face. A low, possessive chuckle escaped his chest.

"Go clean yourself up, Nastya," he murmured, leaning down to press a firm, lingering kiss against my collarbone. "Your mother will be home in an hour."

The mention of my mother sent a sharp, electric jolt of adrenaline through my veins, but it wasn't fear, it was pure, unfiltered thrill.

I gathered my crumpled dress and my lace panties, holding them loosely in my arms just like he had promised I would, and walked out of the study on trembling legs.

Over the next two weeks, our hidden routine turned into an absolute addiction. We couldn't keep our hands off each other.

Whenever my mother left the house for her bridge club or charity luncheons, George would pull me into the pantry, the laundry room, or against the kitchen counter.

I even joined his gym under the excuse of getting fit, just so he could lock the private office door in the back and push me against his leather couch during his lunch breaks.

We went on secret dates across town, hiding in the dark corners of high end restaurants, stealing kisses under the table while my mother thought I was at lectures.

Everything was a dream. I felt completely invincible, like the undisputed queen of George’s world.

Until Julian showed up.

It happened on a quiet Tuesday evening. My mother had gone out of town for a weekend spa retreat, and George and I were planning a long, uninterrupted night together.

I was sitting in the living room, flipping through a magazine, when the front door swung open.

In walked a guy who made my breath catch in my throat.

He was twenty four, tall, broad shouldered, with a lethal, razor-sharp jawline and dark, intense eyes.

He looked like a younger, more dangerous twin of George. He carried a leather duffel bag over his shoulder, exuding a careless, arrogant confidence that filled the entire foyer.

"Julian?" George’s voice echoed from the top of the stairs as he came down to greet him.

"Hey, Dad," Julian said, his voice a deep, smooth baritone.

They shared a brief, firm hug before Julian’s eyes drifted over George's shoulder and landed directly on me.

A slow, crooked smirk spread across his face as he took me in, from my bare legs to the thin straps of my tank top. "And you must be Nastya. My new step sister."

"Step brother," I managed to say, offering a polite smile, though my heart was hammering against my ribs.

There was something in the way he looked at me, too sharp, too observant that immediately put my defenses on high alert.

For the first few days, Julian played the quiet, charming stepbrother. But he was far too smart. He had lived with George long enough to know his father’s subtle habits.

It took him less than forty eight hours to notice the heavy, lingering glances between George and me across the breakfast table, or the way

I flushed whenever George touched the small of my back while passing in the hallway.

The trap snapped shut on a Thursday night.

George was out late finalizing a gym equipment shipment, leaving just Julian and me in the massive house.

I couldn't sleep, so I crept down to the home gym in the basement to get a glass of water from the cooler. I was wearing a satin nightgown that barely hit mid-thigh.

As I turned the corner, a hand reached out from the shadows, grabbing my wrist and pulling me pinned back against the cool mirrored wall.

I gasped, my eyes widening as I looked up into Julian’s dark, smirking face. He was towering over me, smelling like fresh soap and expensive cologne.

"Julian! What the fuck are you doing?" I hissed, trying to wrench my arm free, but his grip was like iron.

"Quiet, stepsister," he whispered, stepping closer until his chest was brushing against mine.

His knee slid between my thighs, forcing them apart through the thin satin. "You know, I tried to play nice. I really did. I told myself you were off-limits... until I checked the gym's security backup drive yesterday."

My blood ran completely cold. "What... what are you talking about?"

Julian pulled his phone from his pocket with his free hand, tapping the screen before holding it up to my face.

My stomach dropped into a bottomless pit. On the screen was crystal clear footage from two nights ago, George pushing me against the bench press, my legs wrapped around his waist while he pounded into me, my head thrown back in pure ecstasy.

"Fucking Dad in the home gym," Julian chuckled darkly, his thumb casually grazing along my jawline. "You're a real nasty little bitch, aren't you?"

"Delete that," I breathed, panic suffocating me. "Julian, please. If my mum sees that…"

"If your mum sees this, Dad loses half his assets, you get thrown out on the street, and this cozy little fantasy you two have collapses," Julian interrupted smoothly.

He leaned down, his lips brushing the shell of my ear, sending a sickening shiver straight down my spine. "I don't want to ruin Dad. But looking at this video... I realize I want a turn."

"No!" I pushed against his chest, tears of anger stinging my eyes. "That's forbidden! You're my stepbrother!"

Julian let out a harsh, mocking laugh, his hand sliding down my waist to grip my ass firmly through the silk dress.

"Forbidden?" he whispered, his fingers digging in. "If fucking me is forbidden, Nastya... then what the fuck do you call what you’re doing with my dad?”
