My Husband’s Forbidden Brother (Dirty Secret Series 1)

“Claire,” Andrei breathed against my lips.

His hand tightened on my waist as our kiss deepened, pulling me close enough to feel the hard evidence of how badly he wanted me.

I should have stepped back.

Instead, I melted into him like I had never been touched before.

The first Blackwell man who touched me was not my husband.

Three months before my wedding, Adrian Blackwell was just a stranger in a hotel bar, just a flicker of warmth in a world drowning in cold, hard reality.

I didn’t know his last name then. All I knew was that he looked at me as if I were whole, not broken; as if I were a woman with choices, not a daughter being sold to save her father’s company.

I had gone to that hotel bar to breathe.

My father had spent the afternoon begging me to understand: our family business was collapsing. Investors had pulled out. Loans were overdue.

The world was waiting for us to fail.

Then the Blackwells arrived with an offer, a merger. A marriage. Me.

I still remembered my father’s hands on mine, his eyes pleading.

“Claire, this will save us.”

Save us. Not me. Us.

So I ran. I wore a black dress that night, determined not to look like someone’s obedient daughter. I ordered something strong, hating the burn as it slid down my throat, and sat alone at the end of the bar, pretending to be brave enough to disappear.

Then Adrian sat beside me, and my escape plan crumbled.

“You look like you’re trying very hard not to cry,” he said, his voice smooth and low.

I should have ignored him. Instead, I laughed.

That was my first mistake.

He smiled like he had been waiting for that sound. “Good,” he said. “You look even beautiful when you smile.”

What a dangerous thing to say. But I was tired of safe things. Safe things had led me to a marriage arrangement with a man I had never loved.

So I let the stranger talk to me. No questions. No pity. Just those green eyes watching me, making me feel, for one stolen night, like I still belonged to myself.

His name was Adrian. Just Adrian. That was all I got. Claire. No last names, no history, no promises.

By midnight, we were in the elevator. By fifteen past, his hand was on my waist, fingers pressing into the fabric of my dress like he was afraid I would disappear. By twenty, my back was against the wall and my fingers were in his hair and his mouth was at my throat, and the floor numbers above the doors had stopped meaning anything; just light, just heat, just the soft sound he made when I pulled him closer instead of pushing him away.

And by sunrise, I woke up in a hotel room beside a man I knew I would never see again. Or so I thought.

I left before he woke, cowardly, maybe, but easier. I didn’t want him to ask for my number or to see the missed calls from my father.

I didn’t want him to know that the girl he touched like she was precious was already promised to another man.

So I walked away.

For three months, I remembered him in pieces. His hands. His mouth. The way he said my name like it was something he wanted to keep.

Then my wedding day came.

I stepped into the chapel and saw him standing beside the altar.

My breath caught.

Adrian.

Black suit. Tense jaw. Green eyes locked on mine like the whole world had vanished around us.

No.

My fingers tightened around my bouquet.

He wasn’t supposed to be here. Not beside the man I was about to marry.

“Claire,” my father whispered, pressing his hand against my arm. “Keep walking.”

But I couldn’t. Because Adrian had gone pale. He knew.

The same memory hit him, the hotel bar, the elevator, the sunrise I escaped before he could ask me to stay. His eyes dropped to my white dress, then lifted back to my face. Something shattered in his expression.

And then I looked at the groom.

Nathaniel Blackwell stood at the end of the aisle, cold and perfect.

Nothing like Adrian.

Adrian looked like fire; Nathaniel looked like he had buried every feeling and built an empire over the grave. His black eyes watched me, void of warmth. Only control.

Then his gaze moved to Adrian. For a fleeting second, something passed between them, hatred, victory, a secret I wasn’t part of but felt trapped within.

My stomach turned cold.

The priest began speaking as I reached the altar, but I barely heard him.

Marriage. Honor. Duty.

Every word felt like a punishment.

Nathaniel took my hand. His touch was firm, possessive, empty, never like Adrian’s.

I forced myself to look at him. “I’m fine”

The ceremony continued. I said my vows with Adrian standing only feet away, promising loyalty while remembering another man’s hands on my skin.

I promised devotion while Nathaniel watched me like he had already won.

Then the priest smiled. “You may now kiss the bride.”

Nathaniel leaned close, and for the first time, I smelled his cologne, clean, expensive, with something darker underneath.

His lips stopped near my ear instead of my mouth. “You should have told me,” he whispered.

My heart slammed once, and I froze. The guests waited. Cameras flashed. The priest smiled like this was romantic.

My voice barely came out. “Told you what?”

Nathaniel’s lips finally touched mine. It was not a kiss. It was a claim. Brief. Cold. Public.

When he pulled away, his eyes stayed on mine.

“That you had already met my brother.”

The chapel erupted in applause.

My blood went silent.

Across from us, Adrian’s jaw tightened, hands curling at his sides as if holding back something unforgivable.

Nathaniel turned me toward the crowd, his hand firm on my waist. To everyone else, we looked perfect, a beautiful bride, a powerful groom, a marriage that saved two families.

But as we walked down the aisle, Nathaniel leaned close again.

“Smile, wife. You are exactly where I wanted you.”

And behind us, Adrian whispered my name.

Not loudly. Not enough for the guests to hear.

But I heard it.

Claire.

I looked back, and that was my final mistake.

Because Nathaniel saw. For the first time since I met him, my husband smiled like he had just won a war I didn’t even know I was part of.
