6 Months As My Brother-in-law's Mistress
My husband is cheating on me with my sister.
I should have been devastated.
Instead, I was furious.
Because Preston didn't just betray our marriage. He got my sister pregnant, lied to his entire family, and built an elaborate story where her baby was supposedly ours through a surrogacy arrangement.
He wanted me to smile, play the loving wife, and raise the child born from his affair.
He should have thought twice before humiliating me.
Because his brother-in-law has a proposal of his own.
Sebastian Greene knows exactly what it's like to be betrayed by Darcia. And instead of quietly divorcing her, he's decided we're going to make them taste their own medicine.
His solution?
Six months.
Six months of pretending to be his mistress.
Six months of secret meetings, stolen touches, and making our spouses wonder just how far we've gone.
It should have been simple.
Revenge.
Nothing more.
But Sebastian doesn't treat me like a discarded wife.
He listens to me. Protects me. Makes me laugh. Looks at me like I'm something worth wanting.
And somewhere between the lies, the forbidden touches, and the nights we were never supposed to share...
I started forgetting that this was supposed to be revenge.
Because the most dangerous thing about pretending to belong to another man...
Is falling in love with him for real.

Chapter: 005Chapter FiveAddie’s POVI turned around slowly, my heart seizing in my chest.Standing behind Sebastian’s chair in casual denim and a jacket was Felix—Preston’s younger brother.A sudden panic flared up in my throat, making my palms sweat against the paper cup.Why was he even at Saint Mary’s?I forced myself to take a breath, trying to calm the racing beat of my pulse. Sebastian was my sister's husband. We were in-laws. It shouldn't be strange for two family members to sit in a public hospital cafeteria sharing a table, right?Why was I sitting here terrified like I had already committed a crime?"Hi, Felix," I forced out, my voice cracking slightly before I cleared my throat to steady it."Hey, Addie," Felix said, walking over with a broad, genuine grin on his face. He nodded respectfully toward Sebastian. "Mr. Greene. Didn't expect to see you down here."Sebastian merely gave a polite, detached nod, leaning back in his chair without offering a single word of explanation.Felix tur

Chapter: 004Chapter FourSebastian’s POVKnowing she was bleeding out in some cheap bed while the bastard, Preston, was fooling around with Darcia made me want to strangle something.That thing, apparently, happened to be the pen with which I was supposed to use in signing a contract.I sat at the head of the conference table, watching the lead investment manager, Henderson, lean back with that smug, self-important smirk plastered across his fat face.These people were stressing the fuck out of me.They had spent the last two hours playing childish psychology games—stalling over minor indemnity clauses, pretending to walk away, pushing for another fraction of a percentage point like they were doing me a personal favor by bringing forty million to the table.Normally, I had the patience of a predator. I would have let them drag their little performance out until they exhausted themselves, then stripped their equity down to the bone before letting them sign.However, the sudden call from Saint Mary

Chapter: 003Chapter ThreeAddie’s POVIgnorance truly was bliss.Because the most painful thing about the truth is that once you see or know it, once you feel it carving into your bones, you can never unknow it.My head knew for a fact that Preston was a liar. It knew that the man I had built my entire twenties around was sleeping with my younger sister.Yet my heart was a pathetic, stubborn organ that refused to follow the rules. It still clung to the years of routine, desperate to prove that the world hadn't actually ended.That was why I had packed his favorite smoked salmon wrap at noon, determined to deliver lunch to his law office just like I had done every single week since we started dating in college.I never made it to his firm.A delivery truck running a red light had T-boned my sedan at the intersection of 4th and Main, sending metal crunching into my driver-side door.Now, I was lying on a gurney in the emergency ward, the harsh fluorescent lights blurring above me while medical moni

Chapter: 002Chapter TwoAddie’s POV"Why confront them right now when all they're going to do is lie straight to our faces?" Sebastian continued in a terrifyingly calm manner. "If they have the audacity to sneak around behind our backs, then we can do the exact same thing."I just stared at him, my mouth slightly open, my head pounding with a throbbing ache."Except we won't hide in cheap hotel rooms," he said, leaning in so close I could smell the bite of bourbon on his breath. "We'll make it so painfully obvious right in front of their eyes. We'll show up to the same dinners, share the same glances, leave the same traces. They'll suspect every single move we make, but because of their own filthy secrets, they won't dare open their mouths to ask us about it."He tapped a single finger against the table, looking at me like a chess player about to take a queen."I want to put them against the fence, Addie. I want to squeeze them until they panic, turn on each other, and see just how bad this fire

Chapter: 001Chapter One Addie’s POV“Your husband is cheating on you with my wife.”The words landed on the tablecloth between our water glasses, flat and unbothered.I sat back against the leather booth, letting out a dry, cracked laugh that sounded ridiculous even to my own ears.“Is this a joke, Sebastian?”I searched his face for a twitch at the corner of his mouth. A smirk, an eye roll, some subtle hint that he was just messing with me.Nothing.He sat there in his charcoal suit, broad shoulders square against the booth, swirling a lowball glass of neat bourbon. Sebastian Greene didn’t tell jokes. He was the kind of man whose name made boardrooms go silent before he even stepped out of the elevator. Right now, he was watching me with a kind of certainty that made my throat dry up.“My wife is your sister, Addie,” Sebastian said smoothly. “I don’t make jokes about family betrayal.”“Then you’ve completely lost your mind,” I snapped, sitting up and planting both palms flat on the table. “Pre
