Chapter 1: Teeth in the Wound

Diane Kenworthy's heels clicked against the scarred concrete floor of the loft like a metronome counting down to disaster. She had come for the black silk dress, the one with the slit that always made investors forget their numbers during gala season. Nothing more. A quick in-and-out at eleven-thirty, after her client dinner ran long and her own closet felt suddenly inadequate.

The industrial space smelled of developer fluid and the sharp bite of Marcus's cologne. She almost called out. Almost let her sister know she was there. Then the sounds hit her—low, rhythmic, unmistakable. A woman's moan that could have been her own voice memo played back at her.

She froze in the doorway to the open bedroom area. Marcus's runner's back flexed under the track lighting, his platinum ring catching the glow as his hand gripped a waist that looked exactly like hers. The woman beneath him arched, waist-length braids spilling across the pillow like dark ropes. Diane Forsythe. Her twin. Taking every thrust with that crooked smile Diane knew too well.

Her stomach lurched hard enough to make her grip the doorframe. The betrayal sat right there behind her ribs, pressing until her breath came short. This wasn't some random fling. This was her fiancé buried inside the one person who had spent their whole lives tearing down everything Diane had carefully built.

"You absolute fucking bitch." The words tore out of her before she could stop them.

Marcus's head snapped up. His face went slack with the kind of shock usually reserved for stock market crashes. He scrambled back, still hard, still glistening with her sister's wetness. Diane Forsythe just propped herself on her elbows, breasts bare and shining with sweat, and met her twin's gaze without a flicker of shame.

"Diane. Jesus. This isn't—" Marcus started.

"Save it." Diane cut him off. Her voice cracked on the last word, but she squared her shoulders anyway, the way she did before delivering a closing argument. "I saw exactly what this is. Breach of contract. Null and void. All of it."

Forsythe slid off the bed with that loose feline grace, not bothering to cover herself. Their bodies were identical—same rich dark skin, same long legs, same small scar on the left hip from when they were eight and fell off the same swing set. The sight of it made Diane's fingers twitch toward an imaginary pair of glasses she no longer wore.

"Come to borrow the dress again?" Forsythe's drawl was low, teasing even now. She twisted one braid around her finger, the same nervous habit she'd had since they were teens. "Or did you finally decide to stop pretending you don't want what I have? Like the negative you keep refusing to develop."

The rage came fast and hot. Diane crossed the room in three strides and slapped her. The sound cracked through the loft like a breaking branch. Forsythe's head whipped sideways, but she didn't stumble. When she turned back, her full lip was already swelling, and her eyes had gone dark with something that wasn't just anger.

"You stole my life in pieces," Diane hissed, grabbing her sister's shoulders. Their faces were inches apart now, mirror images warped by fury. "First Mom's attention. Then every boyfriend who looked at me twice. Now Marcus? My goddamn fiancé?"

Forsythe's breath ghosted across her mouth, warm and ragged. "He came to me, baby. Said you were too cold in bed. Said fucking you felt like signing a merger agreement—dry, precise, and over too fast."

The words landed like another slap. Diane's fingers dug into bare skin, hard enough to leave marks. She could feel the heat radiating off her twin's body, smell the sex and the darkroom chemicals clinging to those braids. Her pulse hammered in her throat, in her wrists, between her legs where traitorous warmth was building against every sane instinct.

Marcus was saying something behind them—protests, explanations, the smooth corporate tone cracking into panic. Neither twin looked at him.

"I hate you," Diane whispered. Her voice had gone breathy, unfiltered in a way it never was in courtrooms or family dinners. "I have hated you my entire life. This is malpractice on my soul."

Forsythe's crooked smile returned, slow and knowing. "Liar." Then she surged forward and crushed their mouths together.

It wasn't gentle. Teeth clacked. Lips bruised. Diane tasted blood—hers or her sister's, she couldn't tell. She meant to push away, to shove this chaos back into the box where it belonged. Instead her hands slid up to grip those braids, yanking hard enough to elicit a gasp that vibrated straight through her own chest.

The kiss deepened against the exposed brick wall, Forsythe's back hitting it with a dull thud. Their bodies pressed flush, identical curves and hollows fitting in ways that felt both natural and obscene. Diane's tailored suit jacket bunched under grasping fingers. Forsythe's bare thigh hooked around her hip, pulling her closer.

Every comparison their mother had ever made pressed between them now. Every time Diane had covered for her sister's mistakes. Every birthday forgotten, every achievement diminished because there were two of them and only one legacy to fight over. The resentment burned in the slick slide of tongues, in the way their heartbeats slammed against each other like they were trying to sync up after thirty-two years of being forced apart.

This is wrong, Diane thought, even as her fingers traced the exact line of her twin's jaw that matched her own. The contact was too much. Too perfect. Like touching herself but with teeth and breath and the low, filthy sound Forsythe made when Diane bit her lower lip hard enough to draw another bead of blood.

She hated how right it felt. Hated the way her body recognized every shift, every press, every catch of breath because it was her own body answering back. The terror of it—of being truly seen—made her grip tighter, made her tongue stroke deeper, made her hate herself for how wet she already was beneath the wool of her pencil skirt.

Forsythe pulled back just enough to speak against her mouth, voice husky and half-broken. "Look at us, baby. Two halves of the same exposure. You wear the guilt like that ridiculously expensive suit, and I wear it like nothing at all. Tell me which one of us is really naked right now."

Diane's answer was another kiss, rougher this time, her hands sliding down to grip her twin's ass and yank her closer. The friction dragged a sound from her own throat that sounded too much like surrender. She felt the self-loathing rise like bile, but it only made her press harder, chase the terrible pleasure of being wanted exactly as she was—flawed, furious, and finally matched.

Marcus's voice cut through the haze. "What the actual fuck?"

They broke apart, chests heaving in perfect sync. Diane stared at her twin's face—her own face—now marked with swollen lips and the faint red imprint of fingers on one cheek. Her hands shook as she adjusted a pair of glasses that weren't there. This was wrong. This was the worst thing she had ever done. And her body was still humming with a need so sharp her knees nearly buckled.

She stumbled backward, wiping her mouth with the back of her hand. The taste of her sister lingered like expensive scotch and shame. Forsythe stayed against the wall, one hand pressed to her bruised lips, that crooked smile slowly reforming despite everything.

Diane didn't look at Marcus. Couldn't. She turned and fled, heels clattering down the metal stairs of the loft like gunshots. The night air outside hit her like a slap, cold and unforgiving against her flushed skin. Chicago's lights blurred through the sudden sting in her eyes.

Her driver was waiting three blocks away. She walked instead, legs shaking, the city swallowing her whole. Every step sent echoes of that kiss ricocheting through her—the exact pressure of those familiar fingers digging into her ass through her skirt, the soft surprised moan that had come from her own throat, the terrifying relief of finally being touched by someone who knew every scar without being told.

By the time she reached her high-rise, the weight of it had sunk into her bones. She was the good one. The reliable one. The twin who quoted contract law and stress-organized her spice rack at two in the morning. Not this. Never this.

Yet when she stripped off her clothes in the marble bathroom, her fingers kept drifting to her own mouth. Tracing the swelling. Remembering how it had felt to be held by someone who knew exactly how hard to pull her hair because they shared the same sensitive scalp.

She avoided the mirror. The thought of seeing her sister's expression on her own face made her stomach roll over again.

At her sleek kitchen island, she tried to work. There were briefs to review, emails from the partners about the upcoming merger that now felt tainted by Marcus's betrayal. Her hands wouldn't stop trembling. The fountain pen she'd collected last month—vintage, ridiculous, never used—rolled across the granite and clattered to the floor.

She left it there.

Instead she pulled out a box of evidence from her latest case, the one with the color-coded labels she was so meticulous about. Her fingers fumbled the tabs. Red for urgent. Blue for discovery. Everything blurred. She kept seeing those identical bodies moving together. Hearing her own recorded voice in her sister's moan.

The phone buzzed on the counter. Unknown number. She almost didn't open the message. When she did, the photo loaded slowly—a blurry shot through the loft window. Two women tangled against brick. One in a power suit, the other naked. Their faces were indistinct but the posture, the braids, the desperate grip of hands... it was unmistakable.

Her throat closed. The image was timestamped twenty minutes ago. Someone had been watching.

Another text came through. This one from a number she knew too well.

Come back. We both know you left something behind.

Diane stared at the words until they swam. Her pulse was everywhere—wrists, temples, the traitorous ache between her thighs that hadn't faded since that brutal kiss. She set the phone down with deliberate care, the way she handled fragile contracts in the office.

But her hand hovered over the screen. One touch. One reply. That was all it would take to step off the edge she'd spent thirty-two years avoiding.

In the darkened window, her reflection watched her. For the first time in her life, she couldn't tell which Diane was looking back.

---

Back at the loft, Diane Forsythe finally pulled on an oversized t-shirt that smelled like darkroom chemicals and yesterday's takeout. Her lip throbbed where her twin had bitten it. She touched the spot absently, tongue darting out to taste the faint copper, eyes half-lidded as the memory replayed like a strip of film she couldn't destroy.

Marcus was pacing, his runner's build tense beneath the expensive shirt he'd thrown on crooked. "Explain this to me. Right now. What the hell was that?"

She laughed, low and rough. The sound cracked in the middle like cheap film. "That, darling, was thirty years of foreplay finally getting interesting. The kind of shot you wait your whole career to capture."

He spun his platinum ring so fast she thought it might fly off. "You were supposed to be my side piece. Not... not whatever fucked up twin thing that was. She was going to marry me. Our families—"

"Our families can choke on their own legacy." She moved to the window, staring out at the Chicago night where her sister had disappeared. The brick still held the heat of their bodies. Or maybe that was just wishful thinking.

The kiss hadn't been planned. Not really. She'd meant to taunt, to push, to watch perfect Diane shatter. Instead she'd felt something crack open inside her own chest when their mouths met. Like finally developing a photo she'd been avoiding for years. It showed too much—every flaw, every need, every way they completed the frame the other left empty.

"She'll come back," she murmured, more to herself than to the man currently spiraling behind her.

Marcus grabbed her arm, fingers digging in with the same pressure her twin had used minutes ago. The similarity made her want to laugh and vomit at the same time. "You listen to me. This ends now. Both of you go back to your assigned roles or I swear I'll—"

She turned, meeting his eyes with the same steady gaze her sister used in court. Their faces really were identical when you stripped away the braids and the bob. Same sharp cheekbones. Same way of lifting one eyebrow in silent judgment.

"You'll what? Tell Mommy?" Her voice dropped to that husky drawl that usually got her whatever she wanted. "Go ahead. Tell the world the Kenworthy twins are fucking each other instead of you. See how that merger looks then."

He released her like she'd burned him. Good. Let him feel a fraction of the heat still simmering under her skin.

Forsythe walked to her makeshift darkroom in the kitchen, ignoring the way her thighs still trembled. She needed to destroy that roll of film she'd shot last week—candid shots of Diane at a charity event, captured from across the room without permission. The ones that showed her twin's perfect posture cracking into something almost human when she thought no one was watching.

Those photos needed to burn. They revealed too much about both of them.

But as she stood over the sink, hands shaking slightly, she couldn't stop replaying the moment their teeth had clacked together. The way Diane had yanked her braids. The helpless sound that had escaped her sister's controlled mouth. The terrifying way it had felt like coming home.

She smiled in the dim light, crooked and certain despite the fear gnawing at her edges.

This wasn't over. It had only just started tearing them both apart.

And God help her, she couldn't wait to see what pieces they left behind.
