My Ex Cheated With My Sister — So I Married His Billionaire Uncle

Part 1
I stared at the dark, purple hickey on my adopted sister’s neck.
It was faint, dusted over heavily with expensive concealer, but unmistakable under the bright ballroom chandeliers.
Heather caught my furious gaze and immediately pulled her silk collar up to hide the mark.
She offered me a tight, overly sweet smile before quickly looking away to avoid my eyes.
Tyler, my fiancé of two years, stood right beside her, acting completely unnatural.
He shifted his weight nervously from foot to foot and avoided looking at me altogether.
We were supposed to be celebrating our incredibly expensive engagement tonight.
The massive luxury hotel ballroom was packed to the absolute brim with both of our families.
Dozens of waiters in crisp white shirts circulated seamlessly with silver trays of expensive vintage champagne.
Soft, romantic jazz played softly from a live string quartet positioned in the far corner of the room.
My mother was chatting animatedly with Tyler’s wealthy parents by a towering, magnificent swan ice sculpture.
Everyone in our tight-knit, wealthy social circle thought this was the absolute perfect match.
Instead, I felt nothing but a cold, hollow clarity expanding rapidly and painfully in my chest.
I already knew exactly what Tyler and my adopted sister Heather had done behind my back.
Last night, I found their secret, highly inappropriate texts on his unlocked phone while he was in the shower.
They weren’t just innocent flirty messages or harmless, misunderstood inside jokes.
They were graphic, undeniable proof of a disgusting, physical betrayal that had been going on for over six months.
My own adopted sister had been sleeping with my fiancé in our shared apartment while I was working late at the office.
I hadn’t screamed, cried, or thrown any heavy objects when I read those horrifying, life-altering messages.
I had simply put the expensive phone back on the nightstand and walked straight out of our shared apartment.
I had gone to a high-end, dimly lit hotel bar downtown, desperately seeking some kind of oblivious, numbing escape.
I drank three incredibly strong martinis in rapid succession and made the most reckless decision of my entire life.
I had approached a handsome, ruggedly powerful older stranger at the bar and taken him up to a luxury penthouse suite.
I didn’t ask his name, and he didn’t ask for mine, preferring the absolute anonymity of the encounter.
It was a night of pure, unbridled physical escape from the crushing, overwhelming reality of my life completely falling apart.
Now, standing in front of the two specific people who had destroyed my trust forever, I felt absolutely zero guilt.
My hands were perfectly, terrifyingly steady as I reached forward for my waiting glass.
I picked up a heavy silver spoon and tapped it firmly against my delicate crystal champagne flute.
The sharp, clear ringing sound cut right through the low, polite hum of the wealthy crowd’s conversation.
The massive, opulent room slowly quieted down as hundreds of people turned to look at the center stage.
Hundreds of expectant, smiling faces turned toward me, waiting patiently for a heartfelt, teary-eyed toast about true love.
I turned my body slowly to face Tyler, who suddenly looked exactly like a terrified deer caught in bright headlights.
I smiled broadly, though my chest felt incredibly tight and my heart hammered violently against my aching ribs.
“I’m officially calling off the engagement,” I announced to the entire room, my voice ringing out clear and uncompromisingly loud.
A collective, dramatic gasp rippled instantly through the gathered guests in a massive wave of pure, unadulterated shock.
My mother completely dropped her expensive crystal glass in sheer, uncomprehending horror.
It shattered loudly against the highly polished marble floor, but nobody moved a single muscle to clean it up.
Tyler’s handsome, perfectly groomed face turned a violent, incredibly ugly shade of scarlet red.
“Are you completely out of your mind?” he hissed under his breath, stepping aggressively right into my personal space.
He reached out quickly and grabbed my bare arm, his manicured fingers digging in with a surprisingly bruising grip.
I yanked my arm back violently, glaring at him with pure, completely unfiltered disgust and seething hatred.
“I know all about you and Heather,” I said, projecting my voice loud enough for the entire front row of wealthy guests to hear clearly.
A heavy, utterly suffocating silence dropped instantly over the grand ballroom like a massive iron anvil.
Heather let out a theatrical, violently trembling sob and covered her flushed face with her perfectly manicured hands.
She stumbled dramatically backward into the staring crowd, desperately acting like the innocent, helpless victim she always pretended to be.
Tyler’s initial shock quickly warped into a defensive, incredibly ugly rage to save face in front of his powerful, judging family.
He pointed an accusatory, shaking finger aggressively at the center of my chest.
“You’ve been completely cold and utterly distant for months!” he yelled loudly, his voice echoing harshly off the vaulted, painted ceiling.
“You’re entirely obsessed with your failing, pathetic career, and you never have any time for me or our relationship!”
He took another threatening, aggressive step closer, his dark, calculating eyes narrowing into vicious, hateful slits.
“And the prominent rumor has it you weren’t exactly sleeping alone in your own bed last night either.”
A fresh, deeply scandalous wave of furious, hushed whispers broke out rapidly among the stunned, gossiping guests.
Tyler leaned in uncomfortably close, desperately trying to intimidate me into humiliated, quiet submission in front of his overbearing parents.
“Who was he, Megan?” he demanded loudly, a tiny drop of angry spit hitting my pale cheek.
“Tell me his name right now, and I swear to God I’ll make him completely wish he was dead.”
I opened my mouth slightly, fully prepared to tell him that I didn’t even know the mysterious, handsome stranger’s name.
But a low, incredibly commanding, impossibly deep voice cut sharply through the tension-filled room before I could speak a single word.
“It was me.”
The dense, packed crowd of wealthy, elite guests parted instantly, as if instinctively yielding to royalty.
A tall, broad-shouldered, incredibly striking man in a meticulously tailored charcoal bespoke suit walked slowly forward.
He exuded absolute, terrifying financial power and a quiet, highly lethal, undeniable menace.
Tyler went completely pale in an instant, all the angry, rushing blood rapidly draining from his shocked face.
“Uncle David?” he choked out pathetically, his voice cracking horribly like a terrified, disciplined child.
David Harrison was the terrifying, legendary patriarch of the massive, multinational Harrison family empire.
He was a legendary billionaire, notoriously ruthless in cutthroat business, and the exact man Tyler had spent his entire pathetic life desperately trying to impress.
David didn’t even spare a single, fleeting glance for his trembling, completely pathetic nephew.
He stopped right next to me, completely ignoring the crowd, and smoothly slid a warm, incredibly possessive arm firmly around my waist.
“She spent the entire night with me,” David said casually to the stunned room, calmly adjusting his incredibly expensive platinum cufflinks.
“And frankly, she was absolutely, mind-blowingly incredible in every single way.”
Tyler swayed unsteadily on his feet, looking exactly like he was going to pass out cold on the spot.
Heather stopped her fake crying instantly and stared at us with her mouth hanging completely wide open in pure, unadulterated shock.
David finally turned his undivided attention to me, his dark, intensely focused eyes entirely unreadable and completely calm.
“Let’s get out of this ridiculous, dramatic circus, darling,” he murmured softly, his voice a rich, vibrating baritone.
He guided me firmly out of the stunned, silent ballroom and straight past the gawking, paralyzed hotel security guards.
He led me gracefully out into the cool, refreshing night air and straight into his waiting, heavily armored, custom black town car.
As we drove rapidly and smoothly away from the luxurious hotel, my massive spike of adrenaline finally crashed hard.
My hands started to shake uncontrollably in my lap as the absolute reality of what I had just done settled in.
I didn’t know what on earth to say to this terrifying, incredibly powerful man who had just completely blown up my life.
David calmly poured a generous measure of amber liquid from the car’s polished mahogany console.
“My traditional, incredibly stubborn grandmother has been relentlessly hounding me to finally settle down,” he said smoothly, staring out the heavily tinted window at the passing city lights.
“And you clearly need a foolproof, highly effective way to completely crush my treacherous, utterly useless nephew.”
He turned his head slowly to look at me, assessing me carefully and methodically like a highly valuable, strategic business acquisition.
“Move into my private, highly secure estate, pretend to be my utterly devoted girlfriend, and act as my public shield against my family’s endless demands.”
“In exchange, I will personally guarantee you the ultimate, completely undeniable revenge on both Tyler and Heather.”
He popped open his expensive briefcase, pulled out a sleek, heavy leather folder, and handed it directly to me.
I looked down slowly at the thick, incredibly detailed legal contract resting heavily in my lap.
Then I looked slowly back up at the incredibly dangerous, completely serious man who could destroy my ex-fiancé’s entire existence with a single, casual phone call.
