Forcefully Marked By My Twin Sister's Fiancé

Isolde~

It was almost evening.

More than three hours had passed, and I was still standing at the far end of the aisle alone.

My ankles ached in the heels I was forced to wear. I kept shifting from one foot to the other, trying to ease the pain, but it didn’t help.

Although I couldn’t see my feet under the overflowing white wedding dress, the sharp sting told me enough — they were already bruised.

My makeup felt heavy on my skin. Sweat trickled down my back and chest, sticking the fabric to me. I was hot, dizzy, and tired of pretending.

And then the whispers started.

“Isn’t Alpha Ryder going to attend his wedding?”

“Why hasn’t he shown up yet?”

“Poor girl”

Tears welled up and burned my eyes.

I bit my lip under the veil so hard I tasted blood.

But the tears fell anyway.

One slipped free.

Then another.

My fingers shook around the bouquet I held, the flowers trembling just like me.

And then…

Through the noise.

Through the whispers.

I heard it.

“Isolde.” Sharp enough to break me.

It was his voice. Alpha Ryder had arrived.

Not to marry me but to destroy me. He called me by my real name. Not Isla but isolde. My eyes burned with unshed tears as realization dawned on me. He knew.....

Towering. Dressed in black. Cold as death. No trace of warmth in his face, no apology in his eyes. He walked down the aisle with slow, deliberate steps; like he was going to war.

Like I was the battlefield.

He stopped beside me at the altar, saying nothing. His jaw was clenched and his aura—suffocating.

The Elder finally stepped forward, clearing his throat with tension wrinkling his brow.

“By the will of the Moon Goddess, under her gaze and the ancient rites that bind wolf to wolf, mate to mate—

We gather to witness the sacred union between Alpha Ryder of the Bloodfang Pack, and Isla of Silver Fang bloodline.”

A wave of discomfort spread across the room. No one spoke.

The Elder pressed on, “Isla, do you accept this binding? Do you offer your heart, body, and wolf if she stirs to the Alpha beside you?”

“Do you vow to serve, obey, and bear his mark, no matter the weight of the bond?”

My lips parted. The answer caught in my throat. But I forced it out, “I do.”

The Elder turned toward Ryder, relief beginning to bloom in his expression, “And do you, Alpha Ryder—”

“I’ll say mine,” Alpha Ryder interrupted, his voice slicing through the moment, “To her. Alone.”

The Elder froze and nodded before stepping back.

Ryder didn’t wait. He stepped closer. So close I could feel the heat of him. Veil still over my face. Makeup streaked with tears.

And then—

He leaned down, brushing his lips against my ear. His voice was razor-wrapped in silk, “You don’t deserve her dress. You don’t deserve my mark. But I’m going to give it to you anyway not because you’re mine to love, but because you’re mine to ruin.”

My spine stiffened. My bouquet shook in my hands.

He went on, “From this moment forward, I vow to be your shadow. Your storm. Your curse in daylight. I’ll touch you like I touched her. Make you beg like she never had to. You’ll sleep in her bed and wake up drowning in her ghost.”

“You think this is punishment? No, Isolde. This is your unraveling. You’ll cry for mercy, and I’ll kiss your tears. You’ll scream my name, and I’ll shove it deeper.”

His breath burned against my skin. His lips brushed my temple.

“You regret taking her place? You will. You’ll regret every breath you’ve stolen since the day she died and when I'm done....”

Then his tongue dragged across the shell of my ear, slow and deliberate as his tone dropped low—more quiet than a whisper, “…you’ll wish it had been you in the casket instead.”

And just like that he stepped back. His face unreadable. His voice, however, thundered through the hall, “Expose her neck. Now.”

The Elder hesitated. His old hands trembled. But Ryder didn’t repeat himself. A warrior stepped forward from the side. One of his, loyal and brutal. He yanked the veil back without ceremony. Pins tore from my hair, scattering like broken stars across the altar floor.

The few guests present gasped.

And then he did what no one else dared; he reached behind my neck, grabbed the delicate chain clasp, and tore it apart with a metallic snap. The dress’s neckline sagged, revealing the bare curve of my neck and shoulder.

I felt naked. Stripped. Offered.

I flinched.

The Elder’s voice shook, “Alpha Ryder, by the rites—”

“Fuck the rites,” Ryder growled.

And then—

He stepped forward. His hand curled around my jaw. Fingers tightening and then he tilted my head back so my throat was bared to him, helpless and trembling, “Look at them,” he hissed under his breath. “Let them see the moment you’re ruined.”

His fangs dropped with a sickening sound. The crowd held their breath.

I didn’t get time to brace.

He bit.

Hard.

Pain exploded through my neck. My scream echoed across the walls. I fought, legs dangling and tears gushing but he didn't stop.

The bond—

The bond slammed into me like a truck.

Heat. Pressure. A searing wave of something dark and brutal that cleaved into my very soul.

Not love. Not devotion.

Just raw, animalistic possession.

He pulled back, blood staining his lips. Mine.

His mouth brushed my ear again as I collapsed against him, legs too weak to stand.

“You’re mine now, little thief.”

“And I will ruin you.”

I couldn’t speak. My vision turned blurry with more tears. Regret. So many regrets. I wanted to rewrite my wrongs. But I knew it was impossible.

All I could do now was serve my punishments. Because I deserved it.
