Married To The Wrong Billionaire Brother

"We have to get married just to enter a country.." Sabrina smiled, staring at the marriage certificate that required her signature.

"It's Imani. They're old-fashioned. It's romantic. We'd get a divorce as soon as we get back."

Finn and Sabrina travel to Imani, a country with a strict no-cohabitation policy for unmarried couples.

To get in without revealing their relationship, they sign a quiet marriage certificate, planning to divorce the moment they return home, treating it as a formality rather than a real marriage. They weren't about to let a customs policy ruin the only vacation they'd managed to steal for themselves after keeping their relationship a secret for years. If signing a temporary marriage certificate meant spending two weeks with each other in paradise for their four-year anniversary, then what was the harm?

They weren't really getting married.

At least not yet.

It was just paperwork.

A harmless little lie.

Their signature is just enough ink to get them through the gates and into the villa they'd booked overlooking the coast.

As they get back, Finn draws up the divorce paperwork, signs his portion, hands it to Sabrina to sign, submit to the registrar and the whole thing would disappear like it never happened.

Just as she's about to sign, her stepfather calls, pulling her into the business appointment she's missed while away. By the time she returns, her puppy has torn the document and coffee has ruined what's left of it, the page warped and unreadable in patches.

She calls her lawyer to draft a new one immediately. She'd collect it first thing in the morning, signs it, get Finn's signature, and submit it before their families find out.

But the next morning, Finn proposed to her for real, dropping to one knee and telling her to be his actual wife. One that he wouldn't hide or hide from neither of their families. Overwhelmed with joy, Sabrina completely forgets to get the divorce decree across to Finn for his signature.

The diamond ring glittered beneath the chandelier and Sabrina couldn't stop staring at it.

After four years of keeping their relationship a secret, he had finally proposed and would be introducing her officially to his family.

"You've looked at that ring at least a hundred times," Finn teased and kissed her hand. "I should've done it sooner."

Warmth spread through Sabrina's chest.

All the waiting had been worth it. The promises about timing and patience had finally paid off.

For the first time in a long while, she felt hopeful. His parents were finally going to find out about them.

"Soon to be Mrs Guidotti," She smiled as Finn poured them each a glass of wine.

"To us."

"To us."

Their glasses clinked together and they started discussing the wedding preparation. The moment they had spent years planning was finally here.

In seconds, Finn pulled her into his arms.

Sabrina laughed as he kissed her forehead, neck, cheek and then her lips.

Slowly, the kiss deepened.

She wrapped her arms around his neck while he caressed her breast, planting his mouth on her hardened nipple, causing her to let out a slight moan.

Engrossed by the pleasure, Sabrina's glass tilted and the red wine splashed across both their outfits.

"Oh shit."

Sabrina pulled back immediately.

Without thinking, she reached into the breast pocket of his suit, pulled out what she assumed was a pocket square and began using it to dab at the stain on his chest.

"Forget it.. we should shower and change." Finn says, taking his suit off, "I can't wait to do all I intend to do to you tonight. By the time we're done, Finn Jr will be on his way." He smirked.

He seductively headed towards the bathroom, watching her unzip her dress.

Before entering, he glanced over his shoulder. "I'll be waiting." Then she heard running water.

She looked down at the black piece of fabric still in her hand.

Without a second thought, she tossed it onto the bed but the material landed awkwardly and unfolded.

That didn't look like a pocket square.

Slowly, she approached the bed, bending over to take a closer look.

Without hesitating, she reached for the black fabric, turned it over and her stomach dropped. This wasn't a pocket square placed in most suits.

It was a thong!

A black lace thong!

Sabrina pressed her lips together, fighting back the bitter after taste of the wine she had minutes ago.

She glared at the fabric, trying to convince herself that she must be mistaken.

It was Tiny. Delicate. And definitely not hers.

Her pulse quickened.

The room suddenly felt very quiet.

She was almost positive that Finn loves her and would never do this to her on the most important day of her life–their engagement night.

A buzzed shrill ring cut from the tension. The ringtone echoed through the large room, causing Sabrina's heart to skip a bit.

Finn's phone ringing on the bed.

Her eyes shifted to the screen and she caught a glimpse of a name she wasn't familiar with.

Right as she was about to reach for the phone, a deep voice startled her.

"Sab, honey... is that my phone?" Finn yelled from the bathroom.

"Ignore it, tonight is all about us, baby," Sabrina tells him as she notices a message notification appeared after the call.

She wasn't trying to snoop. But one line caught her attention.

[The result of that night] ~ Sent Elvira.

Sabrina's fist tightened.

The phone buzzed again. And again.

With trembling hands, she picked it up, and unlocked it. She tapped on it and a message thread opened.

A photo loaded first. Then another. Then a video.

These images struck Sabrina like a bolt of lightning, making her body run cold.

For the first time, she was dumbstruck and stunned to even blink.

On the screen was a blondie baddie dressed like a seductive nurse. The bed wasn't unfamiliar. It was this bedroom.

This room.

This same bed in front of her.

Her legs suddenly became too weak, she could barely stand.

Another attachment appeared beneath the video.

A pregnancy test. Boldly positive. Then an ultrasound image. A caption followed.

[Congratulations, Daddy. Finn Jr will be here faster than we imagined.]

The last message completely broke her into pieces. The phone slipped from her fingers and crashed against the floor.

For a second, Sabrina felt too frozen to move or speak. Her world came crumbling that she didn't realise how painfully her tears had streamed down her face until she heard him.

From inside the bathroom came Finn's voice. "Honey?"

Sabrina couldn't breathe yet as her heart kept racing painfully, she reached for her chest, trying to put herself together.

"Honey, I'm waiting." Finn's voice came out a little flirty.

Four long years of dedication and love, years of choosing him over everyone else, years of believing she was the woman in his heart, ears of imagining a wedding, a home, a family.. years spent building a future with a man she thought would become her husband, years of trust, sacrifice, and unwavering loyalty. And all it took was a thong and a text message to turn those years into a cruel joke.

Her eyes darkened with pain and realization as it closely dawns on her that

Finn never wanted their relationship to be known to anyone.. especially his parents. According to him, the time wasn't right. Perhaps Elvira was the reason he kept their love a secret and will be mad at the slightest hint that they were a couple in public.

Unable to bear the weight of the betrayal any longer, Sabrina hastily zipped up her dress, grabbed her bag, and fled the suffocating atmosphere.

The moment she stepped out of the apartment, she headed for the stairs.

Her legs trembled with every step.

The images she had seen on Finn's phone refused to leave her mind.

Tears blurred her vision as she descended the staircase.

Lost in her thoughts, she missed a step.

A gasp escaped her lips as her body pitched forward.

Just before she could fall, a pair of strong arms wrapped around her waist and pulled her back against a solid chest.

Sabrina froze. For a brief moment, neither of them moved.

Then she looked up.

Standing before her was a tall, imposing man with piercing green eyes and a sharp jawline that looked as though it had been sculpted by the hand of god. He appeared to be in his early thirties.

The chandelier hanging overhead cast a soft glow over his features, making him look almost unreal.

Like someone who belonged on the cover of a fashion magazine.

Up close, however, there was nothing soft about him.

His expression was cool. Intimidating. Unapproachable. He wore a pair of dark pajama bottoms, but his upper body was bare, revealing broad shoulders and a well-defined chest. To Sabrina's embarrassment, her gaze lingered a second too long.

"Are you hurt?"

His deep, slightly hoarse voice broke the silence. He noticed she was visibly shaken and slightly disoriented but he wasn't sure what the cause was. Slowly, his eyes scanned her face and he had to admit this was the first time he's seeing a redhead this stunning.

The world seemed to stop for a second.

The scent of expensive cologne drifted toward Sabrina. For a moment, she found herself distracted by it. Then recognition struck.

He looked exactly like Finn.

Well... almost.

The resemblance was uncanny, but where Finn appeared warm and approachable, this man seemed like a sharper, more intoxicating version.

Finn preferred his hair longer while his brother wore a neat buzz cut, making the differences between them more noticeable.

Finn had mentioned having a twin brother who lived abroad and managed the overseas headquarters of the family business.

Miller.

So this was him.

The brother she had never met.

Before she could say anything, a familiar voice rang out.

"Sabrina!"

She turned.

Finn stood at the top of the staircase.

The moment his eyes landed on Miller's shirtless body and his hand resting on her waist, his expression darkened.
