PLAYING WITH FIRE: My Obsessed StepBrother

chapter 3

Chapter 3

Morning light filtered through the curtains, soft and golden, but my body was already buzzing with leftover heat from last night. I had barely slept, replaying every moment—Ethan standing in the shadows, watching me naked and unashamed, his fists clenched and raw hunger burning in his eyes. It left me aching. I slipped my hand under the duvet and slowly circled my c**t, imagining his hand instead, but I stopped before I could finish. His denial was part of the game. I would let the tension build until he couldn’t hold back anymore.

I dressed carefully for the day in a fitted white sundress that skimmed my hips, thin enough to hint at the lace bra beneath when the light hit just right. Innocent on the surface, deadly underneath.

Downstairs at breakfast, the family had gathered around the dining table. Elena chattered about the garden renovation while my father scrolled through emails. Ethan sat like a coiled spring, his dark eyes locking onto me the second I entered.

“Morning, big brother,” I said sweetly, sliding into the seat across from him. I crossed my legs slowly, letting the hem of my dress ride up.

His fork paused mid-air, and a muscle in his jaw ticked. “Sophia.” The word came out sharp, but I caught the flare in his gaze as it dropped to my cleavage for a split second before snapping back up.

Elena smiled, oblivious. “You two catching up today? It’s been so long.”

“Oh, we will,” I replied, holding Ethan’s stare. Under the table, I let my foot brush slowly against the back of his leg. He stiffened but didn’t pull away. The contact sent electricity racing through me. His obsession was a live wire, and I was determined to push it harder.

After breakfast, I went upstairs and checked my phone. Marcus had replied to my text from last night—he was in town for business. Perfect. I invited him over for drinks that evening. “How about our regular catch-up at the mansion?” I typed and sent.

The day passed in a haze of unpacking and light family time, but my mind stayed fixed on Ethan. I caught him watching me from across the garden while I took a phone call outside. He gripped his phone tightly. Good. Let him simmer.

By evening, Marcus arrived right on time—tall, with an easy smile and a tailored shirt. He greeted me with a warm hug at the door. “Sophia, you look fabulous. Europe clearly agreed with you.”

I laughed, linking my arm through his as I led him to the sitting room. “Flattered. Come on, the bar is stocked.”

We settled onto the leather couches with glasses of whiskey. Conversation flowed easily—stories from Milan, his latest deals—and I laughed a little louder than necessary, touching his arm when he made a joke. I knew Ethan was somewhere in the house, probably watching through the security feeds like he always did.

Sure enough, Ethan appeared in the doorway like a gathering storm. His white shirt had the sleeves rolled up, revealing powerful forearms, and his eyes locked on Marcus’s hand resting casually near my shoulder.

“Ethan, this is Marcus,” I said brightly. “An old friend from Milan. Marcus, this is my stepbrother, Ethan.”

Marcus stood and offered a handshake. Ethan took it, his grip visibly tight. “Stepbrother,” he repeated, voice low and edged. “Pleasure.”

The tension was immediate. Marcus tried to talk business, but Ethan’s responses were curt, his gaze rarely leaving me. After fifteen minutes of heavy silence, Marcus checked his watch.

“I should head out. Early meeting tomorrow. Sophia, how about dinner soon?”

“I’d love that,” I said, walking him to the door. I hugged him goodbye a second longer than necessary, feeling Ethan’s stare burning into my back.

The moment the front door closed, the air shifted.

Heavy footsteps echoed behind me. Before I could turn, Ethan grabbed my wrist and pulled me down the dark hallway, away from the main areas. He didn’t stop until we reached the shadowed landing near my bedroom stairs. He pressed my back against the cool wood paneling, caging me with his body.

My heart hammered wildly. Up close, he was overwhelming—tall, muscled, radiating heat and barely leashed anger. One hand braced beside my head, the other gripping my waist.

“You let him touch you,” he growled, voice dangerously low, his breath fanning across my lips. “You laughed at his jokes, even though they weren’t funny, and you invited him into our house.”

A thrill shot through me. This was the crack I had been waiting for.

I tilted my head up, meeting his stormy eyes with a sweet, innocent smile. “Are you jealous, big brother?”

The word detonated between us. Ethan’s control finally snapped. A low, feral sound escaped his throat as he crushed his mouth to mine. The kiss was possessive and demanding—no gentle exploration, just raw hunger. His tongue claimed mine, tasting of whiskey and repressed desire. I moaned into his mouth, fisting his shirt and pulling him closer.

He released my wrist only to slide his hand under my dress, fingers tracing up my thigh. I opened my legs without thinking. When his palm cupped my lace-covered p***y, I gasped. I was already soaked.

“f**k, Sophia,” he rasped against my lips. “You’re dripping for me. This is what you wanted, isn’t it? Pushing me until I break.”

“Yes,” I whispered, rocking against his hand. “I saw you last night… watching me. How long have you been obsessed with me, Ethan? How many times have you jerked off thinking about me?”

He shoved the lace aside and plunged two thick fingers deep inside me without warning. I cried out, the sound swallowed by another bruising kiss. He pumped them roughly, curling to hit that perfect spot while his thumb circled my swollen c**t. Pleasure crashed through me in waves. His body pinned me firmly to the wall, his hard c**k pressing insistently against my hip through his trousers—huge and throbbing.

“Mine,” he growled between kisses, biting my lower lip. “No one else touches what’s mine. Say it.”

“Big brother,” I breathed, knowing it would drive him wild.

He growled and f****d me harder with his fingers, stretching me, his palm grinding against my c**t. My legs shook. I was so close already—years of tension exploding under his touch. Then he added a third finger, filling me completely, while his mouth moved to my neck, sucking hard enough to leave a mark.

“c*m for me, you little tease,” he commanded, voice rough with need.

I shattered. My walls clenched around his fingers as intense pleasure ripped through me. I bit his shoulder to muffle my cry, my body shaking. He didn’t stop, drawing it out until I was whimpering, oversensitive and gasping.

When he finally pulled his hand away, he brought his fingers to his mouth and licked them clean, eyes locked on mine with dark satisfaction. “This changes nothing publicly. But in this house? You’re mine to ruin.”

I smiled softly, still catching my breath, my body vibrating. “We’ll see about that, big brother.”

He stepped back, adjusting himself with a pained groan, then walked away without another word. I slid down the wall slightly, thighs slick, heart still pounding.

The game had just leveled up.

And I was already addicted to the way he broke.
