Mark of Sin: Bound to the Cruel Alpha

He kept pushing deeper, centimeter by relentless centimeter. I felt every millimeter of the stretch as he filled me past any limit I had known.

"It hurts..." I breathed, eyes squeezed shut, nails scoring his back.

He sank further. A sharp, piercing pain tore through me; something inside gave way and tears spilled over my lashes.

Magnus froze the instant he was fully seated, muscles locked and trembling with the effort of restraint. His forehead pressed to mine; his breath came in harsh, ragged bursts.

"There... Now you’re completely mine," he growled through clenched teeth. "Just breathe. Get used to me."

I lay beneath him, lungs working hard, feeling the bright edge of pain slowly dull into something else—an overwhelming fullness, a profound closeness, a sense of being joined in a way that felt almost sacred.

"You can... you can move," I finally whispered.

It was a mistake.

Something in his eyes shifted in an instant. The last fragile threads of control vanished. His pupils swallowed every trace of color until only absolute black remained. Fangs lengthened, gleaming in a predator’s snarl. The mating heat crashed over him completely.

"So my girl wants more..." The voice that left him was no longer fully human. "Good. Because I won’t stop now."

He withdrew almost all the way. I barely managed a breath before he drove back in with one hard, devastating thrust that forced the air from my lungs.

Then he began to move.

Hard. Deep. Merciless. Over and over, setting a brutal rhythm that set every nerve alight. His hands clamped around my hips hard enough that I knew the bruises would bloom dark by morning, yet the ache tangled with rising pleasure until I couldn’t tell them apart. I clung to his shoulders, arching, trying to press closer to the scorching heat of him, gasping for air with lips gone dry from endless moans.

"Mine," he snarled with every thrust. "Only mine."

He hooked his arms under my thighs and rose onto his knees, lifting me so my toes no longer touched the mattress. I hung in his powerful grip, shoulder blades pressed to the bed. The new angle drove him impossibly deeper. He found that hidden place inside me and struck it again and again without mercy. A raw scream tore from my throat; his name left me like a prayer.

"Magnus... I... I can’t... too much..." The words came out broken as my fingers twisted in the sheets until the fabric tore under the strain.

"You’re so close. Come for me."

My body obeyed as if it had no choice. Pleasure detonated along every nerve like lightning. The orgasm ripped through me with stunning force, tearing me apart, blinding me. I screamed his name, arching hard, clenching around him while stars exploded behind my closed lids.

Magnus never slowed. Never stopped. He kept driving into me with the same savage intensity.

"You’re so sweet when you come. I want more. One isn’t enough."

"I can’t... I’m too sensitive..." I tried to twist away, but there was nowhere to go. He held me locked in place, forcing me down onto him again and again.

Suddenly he pulled free. My eyes flew open in confusion—and in one powerful motion he flipped me onto my stomach. Rough hands hauled my hips up, forcing me onto my knees, palms braced against the mattress.

"Stay like this," he growled, settling behind me.

I felt the broad head of him nudge against my entrance once more. Everything felt different from this angle—more vulnerable, more exposed, more completely at his mercy. I couldn’t see his face or the hunger in his eyes. I was utterly in his power.

"Magnus, wait—" I tried, but he was already pushing in.

Deeper. So much deeper. Until I felt him press against something deep inside me, something that made my breath catch.

He buried himself to the hilt in one powerful thrust. A broken moan spilled into the pillow as my fingers twisted in the sheets. It was too much—too deep, too full, too overwhelming.

"Perfect," he snarled, hands clamping hard on my hips to hold me still. "Fucking paradise... You were made for me."

Then he began to move again.

Harder. Rougher. Deeper. The mating heat had stripped away every trace of restraint, leaving only something primal and relentless. Each powerful thrust drove me into the mattress. The room filled with the raw sounds of flesh meeting flesh, my helpless moans, and his continuous low growls.

"Mine," he repeated with every stroke, like a mantra. "My mate. Mine. No one else will ever touch you. Never."

Despite everything I had already felt, tension began to coil inside me once more. My body answered him like a drawn string beneath a master’s hand, surrendering completely.

Then something changed. A strange pressure bloomed deep within me—swelling, expanding, stretching me even further. I tried to twist around, but Magnus’s hand pressed firmly between my shoulder blades, pinning my chest to the pillow.

"Don’t fight it," he growled, voice thick with warning and dark triumph. "The knot is forming. We’re locking together."

The knot.

Panic instantly exploded in my chest.

"No! Magnus, stop! I’m not ready—take it out!" I struggled, tried to crawl forward, but it was already too late.

The knot swelled fully inside me, locking us together with brutal finality. The stretch bordered on impossible. I couldn’t move. Couldn’t escape. We were bound, sealed, and there was no breaking free.

"Too much... it’s too much... it won’t fit..." I sobbed into the pillow, feeling impossibly full.

"It fits," Magnus growled. One hand slid beneath me to rest on my lower belly; the other found the still-sensitive place between my thighs. "You were made for this. You’re perfect."

His fingers worked with devastating precision. Even through the overwhelming stretch, pleasure rose again, mixing with the intensity until the two became indistinguishable.

"Come for me again," he ordered, voice rough with strain. "While I fill you."

I felt the first hot pulse of him spilling deep inside. Wave after endless wave, locked in by the knot so that nothing could escape. He pressed harder, shifting his hips just enough—and stars exploded behind my eyes.

Another climax tore through me, electric and shattering. I gasped and shuddered in his arms while tears slipped down my cheeks. His hands gentled, stroking my hips and thighs as the pleasure crested and slowly receded.

Magnus lowered himself carefully over my back, covering me with his weight without crushing me. We lay locked together, breathing hard. I felt every heavy beat of his heart against my spine, every deep pull of his lungs, while the knot held us bound in the aftermath of the claim.

"This is only the beginning, Lang," he growled against my ear, the sound stripped of everything human—nothing left but pure animal hunger.

"I’m going to knot you so many times you’ll lose count. The knot will ease... and then I’ll take you again. And again. Until the heat finally burns out. That won’t be soon. Three days at the least. Maybe longer. I’ll make it good for you... drink every one of your moans. Savor every drop of your pleasure."

His mouth found the sensitive place just behind my ear. Fangs grazed the skin in a slow, deliberate caress but did not break it.

"Are you ready for that, Jane?" The low rumble vibrated through me. "Ready to belong to me completely? Because after these three days you’ll be mine and only mine. Forever. Though... you’ve always been mine. Right now, only we know it. Soon every living thing will scent my claim on your skin. And I will never let it fade. Not ever again."
