PINNED BY MY STEPFATHER

Crossing The Line

Chapter 10

Derek’s POV

The apartment settled into silence after Mom closed her bedroom door.

The only sounds were the faint hum of the refrigerator and the thunder of my own heartbeat.

I stood frozen in my room, back against the door, trying to get my body to calm down. It didn’t work. Every nerve felt raw, electrified by Marcus’s parting words.

A soft knock broke the quiet.

“Derek.” His voice was low, controlled, but edged with something darker.

I opened the door before I could stop myself. Marcus filled the frame, his broad shoulders tense, dark eyes locked on mine.

The hallway light cast shadows across his face, highlighting the sharp line of his jaw and the silver in his hair.

He stepped inside without asking, closing the door behind him with a quiet click that sounded final.

“We said boundaries,” I whispered, even as my body betrayed me.

My c**k was already half-hard, aching from the almost-kiss earlier.

“You said boundaries.” Marcus moved closer, backing me toward the bed. “I’m respecting your mom. But this thing between us is eating us both alive.” His hand rose, finally cupping my jaw firmly.

His thumb stroked my lower lip again, the same teasing touch from the kitchen. “Tell me to leave right now, and I will.”

I couldn’t. The word lodged in my throat. Instead, I grabbed his shirt and pulled him down into a kiss.

It was desperate, clumsy at first, months of confusion and wanting to explode between us.

Marcus groaned low in his chest, taking control instantly.

His mouth was hot, demanding, tongue sliding against mine as he pushed me onto the bed.

The weight of him pinned me down, exactly like that first night, and I whimpered into his mouth.

“f**k, Derek,” he growled, breaking the kiss to trail his lips down my neck. “You have no idea what you do to me.”

His hands worked fast, shoving my shirt up and over my head.

I fumbled with his buttons, exposing the hard planes of his chest, the light dusting of hair.

When his mouth closed over my n****e, I arched off the bed with a sharp gasp. Pleasure shot straight to my c**k, making it throb painfully against my jeans.

Marcus chuckled darkly. “So sensitive. My shy, untouched boy.” The possessive words sent another jolt through me.

He palmed me through my pants, squeezing just right. “It's already so hard for your stepfather.”

The taboo word made me moan. Shame and arousal twisted together until I couldn’t tell them apart. I bucked into his hand, desperate. “Marcus… please.”

He stripped me efficiently, then himself. Naked, he was an overwhelming, thick, hard c**k curving up against his stomach, muscles honed from years I couldn’t imagine.

He retrieved a small packet of lube from his discarded pants, clearly prepared.

The sight made my stomach flip with nerves and need.

“First time properly,” he murmured, slicking his fingers. “I’ll make it good.”

He kissed me again as one finger pressed inside me. The stretch burned, but his mouth distracted me, his free hand stroking my c**k in slow, perfect pulls.

Soon one finger became two, scissoring gently, then curling against that spot that made stars burst behind my eyes.

“Marcus…” I gasped, hips rolling uncontrollably.

“That’s it,” he praised, voice rough. “Let me hear you.”

He added a third finger, stretching me open until I was trembling, begging.

When he finally pulled back and positioned himself, I was beyond thought.

The blunt head of his c**k pressed against my hole, then pushed inside in one long, steady thrust.

The fullness was overwhelming. Pain flared, then melted into deep, aching pleasure as he bottomed out.

Marcus buried his face in my neck, groaning. “So tight. f**k, Derek… you feel perfect.”

He started moving slow at first, then deeper, harder. Each thrust dragged against that sensitive spot inside me, sending waves of ecstasy through my body.

I clung to his shoulders, nails digging into his skin, moans spilling from my lips that I couldn’t hold back.

The bed creaked softly. We both knew Mom was just down the hall, and the risk only heightened everything.

Marcus covered my mouth with his hand as he f****d me harder, hips snapping with controlled power.

“You’re mine now,” he whispered against my ear. “My secret. My boy.”

The words pushed me over the edge. Pleasure crashed through me like a breaking wave.

I came hard between us, spilling over my stomach with a muffled cry.

My hole clenched around him, and Marcus followed seconds later, burying himself deep as he pulsed inside me, groaning my name like a prayer.

For long moments, we stayed locked together, breathing ragged.

He kissed me softly, almost tenderly, then pulled out carefully. The loss made me feel empty in more ways than one.

Marcus cleaned us up with a towel from my bathroom, then lay beside me, pulling me against his chest.

His fingers traced lazy patterns on my back.

“We can’t do this again,” I whispered, even as I pressed closer. Guilt was already creeping in, cold and heavy. Mom’s smiling face flashed in my mind. “This was a mistake.”

Marcus’s arm tightened around me. “It wasn’t. And we both know it won’t be the last time.”

He kissed my temple. “Sleep. We’ll figure out the rest tomorrow.”

But sleep didn’t come easily. As his breathing evened out, I lay awake staring at the ceiling, body sore in the best and worst ways.

The boundaries I had tried so hard to set were shattered.

The secret now lived inside me,literally and the weight of it pressed heavier than ever.

Outside my room, the apartment was quiet. Mom slept peacefully, trusting the two men she loved most.

I wondered how long we could keep this from destroying her.

And how long I could pretend I didn’t already crave more.
