THE BAD TWIN 🫦

Smut By Anastasia Williams

The rain hammered against the windshield like a thousand accusing fingers as Sophia gripped the steering wheel, her knuckles white. Elena's car—now her car—skidded slightly on the slick highway, the crash site still fresh in her mind. Twisted metal, shattered glass, her sister's body crumpled like a discarded doll. Sophia hadn't meant for it to happen that way. A heated argument, Elena grabbing the wheel, the world flipping upside down. But in the chaos, Sophia saw her escape: from Rico, that piece of shit boyfriend with his fists and his drug debts. Rico thought Sophia was dead now. The cops thought Elena had survived. Perfect swap. Identical twins, after all. Same raven hair cascading to their waists, same piercing green eyes, same full lips that men like Marcus couldn't resist.

Marcus. Elena's fiancé. The man who'd proposed to the "good" twin—the one who baked cookies for church fundraisers, who volunteered at animal shelters, who never spread her legs for anyone but him in missionary position under the covers. Sophia smirked through her tears. She'd always been the wild one, the slutty shadow, fucking strangers in club bathrooms, snorting lines off bar counters. But now? Now she was Elena. Time to play the part.

The funeral was a blur of black dresses and sympathetic whispers. Sophia stood by the casket, staring at her own face—Elena's face—pale and peaceful in death. Marcus loomed beside her, his hand possessive on her lower back, fingers digging in just a bit too hard. He was built like a god carved from marble: broad shoulders straining his suit, dark hair tousled, jawline sharp enough to cut glass. His blue eyes, usually so adoring when fixed on Elena, now held a flicker of something darker as they raked over Sophia.

"I'm so sorry, baby," he murmured, lips brushing her ear. "We'll get through this. You're safe now."

Safe. The word twisted in her gut like a knife. If only he knew.

That night, in Elena's—her—apartment, Marcus insisted on staying. "You shouldn't be alone," he said, pouring them both whiskey. Sophia nodded meekly, channeling her sister's demure vibe. But as the alcohol burned down her throat, she felt his gaze lingering. He sat too close on the couch, thigh pressing against hers.

"Tell me about the crash again," he said softly, his voice a low rumble that sent unwelcome heat pooling between her legs. Fuck, he was hot. Elena had always bragged about his cock—thick, veined, the kind that stretched you until you screamed.

"I... I don't remember much," Sophia lied, her voice a whisper. "The rain, the skid... then nothing."

His hand slid to her knee, squeezing. "You seem different, Elena. Like something's... off."

Her heart pounded. "Grief does that."

He leaned in, breath hot against her neck. "Prove it's you. Kiss me like my Elena would."

Sophia hesitated, then pressed her lips to his—soft, tentative, the way Elena probably did. But Marcus growled, grabbing her hair and yanking her head back. "No. That's not right. Elena kisses like she's starving for me. Try again, slut."

Slut? Elena wasn't a slut. Sophia's pulse raced as she dove in harder, tongue thrusting into his mouth, hands clawing at his shirt. He moaned, but then shoved her back. "Too aggressive. Elena's gentle. What's wrong with you?"

Before she could respond, he flipped her over the couch arm, hiking up her black dress. "Maybe you need a reminder of who you are." His palm cracked against her ass, hard enough to sting through her panties. Sophia gasped, shock mixing with a forbidden thrill. Rico had hit her, but never like this—never with that edge of possession.

"Marcus, what—"

"Shut up, Elena." Another smack, then his fingers hooked into her lace thong, ripping it aside. "Your pussy's wet. Is this turning you on? My sweet Elena, dripping like a whore?"

Sophia bit her lip, mortified and aroused. She wasn't Elena, but his words ignited something raw. "Please..."

"Please what?" He rubbed his thumb over her clit, rough and unrelenting. "Beg like Elena would. Beg for my cock to fill that tight little cunt."

Her mind screamed to stop, but her body arched. "Fuck me, Marcus. Please, shove your big dick inside me."

He chuckled darkly, unzipping. "That's not Elena's words. She says 'make love to me.' But fine, impostor. I'll fuck the truth out of you."

He slammed into her without warning, his thick shaft stretching her walls, bottoming out with a grunt. Sophia cried out, the pain-pleasure ripping through her. He pounded relentlessly, one hand fisting her hair, the other spanking her ass red. "You think I don't notice? The way you walk, sluttier. The scar on your thigh—Elena's didn't have that. Who the fuck are you?"

"I'm Elena!" she gasped, but her hips bucked back, meeting his thrusts.

"Liar." He pulled out, flipping her onto her back, shoving her legs wide. "Look at me while I ruin this fake pussy." His cock glistened with her juices as he drove back in, deeper, hitting that spot that made her see stars. "Elena's cunt clenched differently. Tighter, sweeter. Yours is greedy, sucking me in like a vacuum."

Sophia moaned, nails digging into his back. "Harder, you bastard. Fuck me like you mean it."

He laughed, a cruel sound. "See? Elena never talks dirty. But I like it. Maybe I'll keep you anyway." His pace brutalized her, balls slapping against her ass, sweat dripping onto her tits. She came first, screaming, her walls pulsing around him. He followed, flooding her with hot cum, growling "Elena" like a prayer.

After, he held her, but his eyes were calculating. "Tomorrow, we'll test more. Every imperfection gets punished."

Sophia lay there, spent and terrified, but for the first time in years, she felt seen—not as Elena, but as herself. The darkness in his eyes mirrored her own.

The next morning, Marcus woke her with coffee, acting normal. But as she dressed, he watched. "That's not Elena's bra. Hers are white cotton. Yours is black lace, like a hooker's."

She froze. "I... bought new ones."

"Liar." He dragged her to the bedroom, bending her over the dresser. "Time for correction." His belt whistled through the air, lashing her bare ass five times, each strike leaving welts. Sophia whimpered, but her pussy throbbed.

"Count them, Elena. Or should I say, Sophia?"

Her blood ran cold. He knew.

"Yes, I fucking know." He dropped the belt, fingers plunging into her soaked folds. "Elena's pussy was shaved smooth. Yours has that landing strip. Slutty touch." He finger-fucked her hard, three digits stretching her, thumb on her clit. "Admit it, or I'll stop."

"I'm Sophia," she gasped, grinding against his hand. "Elena's dead. I took her place."

"Good girl." He yanked his pants down, cock springing free—harder than last night. "Now, suck it like the bad twin you are."

She dropped to her knees, mouth watering. Elena probably gave prim blowjobs. Sophia deep-throated him, gagging on his length, saliva dripping down her chin. "Fuck my face," she mumbled around him.

Marcus groaned, thrusting into her throat. "Elena's mouth was gentle. Yours is a cock-hungry hole." He face-fucked her until tears streamed, then pulled out, painting her face with cum. "Wear it all day. Reminder you're mine now."

Sophia licked her lips, tasting him. "Why not turn me in?"

"Because," he said, wiping a streak off her cheek and feeding it to her, "I've always wanted the dirty one. Elena was boring. You? You're filth I can mold."

Days blurred into a haze of deception and depravity. By day, Sophia played Elena at work, in social circles—smiling, polite. By night, Marcus exposed every flaw. "Elena's laugh is lighter," he'd say, then tie her wrists to the bedposts, edging her with a vibrator for hours. "Beg properly, Sophia. Or cum without permission and I'll whip that clit."

"Please, Marcus, let me cum on your toy. My pussy's aching for it, you sadistic fuck."

He'd smirk, denying her until she sobbed, then fuck her ass—something Elena never allowed. "Tight virgin hole," he'd grunt, lubing his cock and inching in. "Take it all, impostor. Scream Elena's name while I ream you."

Sophia did, her cries echoing as he pounded her backdoor, fingers rubbing her clit until she squirted. The pain burned, but the fullness, the wrongness—it made her feel alive.

One evening, at a dinner party with Elena's friends, Marcus slipped a remote vibe into her panties. "Be perfect Elena, or I'll buzz you to hell."

She chatted, laughed—too loud once. The vibe roared to life, high setting. Sophia clenched her thighs, face flushing. "Excuse me," she muttered, fleeing to the bathroom.

Marcus followed, locking the door. "Imperfection noted." He shoved her against the sink, yanking down her dress. "Spread those legs, whore twin."

"Here? They'll hear."

"Good." He buried his face in her cunt, tongue lashing her clit, sucking hard. Sophia bit her fist to stifle moans. "Taste different too," he murmured. "Sweeter, like sin." His fingers curled inside, hitting her G-spot. "Cum on my face, Sophia. Flood me."

She did, juices soaking his chin as she shuddered. Then he stood, cock out, bending her over the sink. "Now, my turn." He fucked her raw, mirror reflecting her debauched expression. "Look at yourself. Not Elena. My dirty secret."

His thrusts slapped wetly, hand over her mouth as someone knocked. "Occupied!" he barked, cumming deep inside her.

Back home, the games escalated. Marcus built a "punishment room"—Elena's old closet, now with restraints, whips, plugs. "For every lie you tell the world," he said, chaining her spread-eagle. "I own the truth."

He teased her nipples with clamps, tugging until she whined. "Elena's tits perked differently. Yours beg for abuse." Then he'd fuck her tits, cock sliding between them, pre-cum lubing the way. "Spit on it, slut. Make it messy."

Sophia obeyed, drool dripping as he tit-fucked her, then shot ropes across her chest. "Rub it in. Wear my cum like lotion."

She did, skin sticky, feeling marked. Owned. Seen.

But the obsession deepened. Marcus started calling her Elena during sex, even knowing. "Ride me, Elena," he'd command, lying back as she straddled him. Sophia ground down, pussy swallowing his cock, but the name stung—and aroused.

"Say you're Elena while you fuck yourself on me."

"I'm Elena," she moaned, bouncing harder, tits jiggling. "Your perfect fiancée, taking your fat dick."

"Liar." He'd flip her, pinning her down, choking her lightly. "You're Sophia, the killer twin. Cum admitting it."

The words tore from her: "I'm Sophia! I killed her! Now fuck me harder!"

He did, rutting like an animal, both cumming in a frenzy of hate-lust.

The punishments became ritual. Every evening Marcus would inspect her like livestock at auction. He’d make her strip slowly—piece by piece—while he sat in the leather armchair that used to belong to Elena’s father, legs spread, cock already half-hard in his slacks.

“Hands behind your head. Elbows out. Show me everything.”

Sophia obeyed, breasts thrust forward, nipples tightening in the cool air. He circled her, silent at first, then cataloguing flaws with clinical cruelty.

“Elena's nipples were smaller. Pinker. Yours are fat and dark—like they’ve been sucked raw too many times.” He pinched one viciously, twisting until she hissed. “How many mouths have these been in, Sophia? Twenty? Thirty?”

“More,” she admitted through gritted teeth, cunt already slick.

He slapped her tit—hard—watching it jiggle and redden. “Slut confession hour starts now. Tell me the filthiest thing you did while Elena was still breathing.”

She swallowed. “I let two guys double-penetrate me in a club bathroom. One in my pussy, one in my ass. They didn’t even ask my name. Just bent me over the sink and used me like a cum-dump. I came so hard I pissed a little on the floor.”

Marcus’s eyes darkened with lust and rage. “And Elena? She was home knitting scarves or some shit while her twin sister acted like a street whore.”

He grabbed her by the throat, not choking—just holding. “Kneel.”

She dropped. He unzipped, cock springing free—thick, veined, already leaking. The head was flushed angry purple.

“Open.”

She did. He didn’t ease in. He fucked her mouth like a cunt—deep, brutal strokes that made her gag and drool. Tears streamed down her cheeks as he held her head still and pistoned.

“Elena's throat was tighter. She never deep-throated. You? You take it like you were born for cock.” He pulled out, strings of spit connecting her lips to his shaft. “Beg me to throat-fuck you until you pass out.”

“Please,” she rasped, voice wrecked. “Choke me with your dick. Use my throat. Make me black out on your cum.”

He laughed low. “Good girl.” Then he shoved back in, balls-deep, holding her nose against his pelvis until her vision spotted. She struggled, hands clawing at his thighs, but he didn’t let up until her body went limp for a second. Only then did he pull out, letting her gasp and cough.

“Pathetic. Elena would’ve fainted from fear. You just get wetter.”

He dragged her to the punishment room by her hair. Inside: the new additions he’d installed over the week—a St. Andrew’s cross bolted to the wall, a padded spanking bench, a shelf of toys that looked more like torture devices.

“Choose your poison tonight.”

Sophia’s eyes landed on the thick black anal plug—the one with the wide base and the word “WHORE” engraved in silver letters across the flared bottom.

“That one,” she whispered.

Marcus’s smile was feral. “Of course it is.”

He bent her over the bench, cuffing her wrists and ankles so she was spread and immobile. Her ass presented high, cunt glistening, dripping onto the leather.

“Elena's asshole was virgin until I claimed it on our engagement night. Sweet, reluctant little pucker. Yours?” He spread her cheeks wide. “Already winking at me. Greedy.”

He spat directly on her hole, watching it clench. Then he worked two fingers in—rough, no lube beyond his spit. Sophia moaned, pushing back.

“Desperate little anal slut.” He added a third finger, scissoring, stretching. “Tell me you want it bigger than Elena ever took.”

“I want it bigger,” she panted. “I want you to wreck my ass. Ruin it so no one else can ever feel good in there again.”

He growled approval, pulling his fingers free. The plug was cold when he pressed the tip against her. He didn’t go slow. He pushed—steady, merciless pressure—until the widest part popped past her ring. Sophia screamed, body jerking against the restraints.

“Fuck—too big—Marcus—!”

“Take it,” he snarled, twisting the base until the word WHORE sat perfectly visible between her cheeks. “Look at that. My marked property.”

He stepped back to admire, then slapped the base—hard. The jolt sent pain and pleasure shooting through her core. She whimpered.

“Now the real fun.”

He retrieved the hitachi wand—the industrial-strength one—and pressed it directly to her clit, turning it on high. Sophia bucked instantly.

“Oh god—fuck—too much—!”

“Shut up and cum.” He held it there, relentless, while he slowly fucked the plug in and out—shallow thrusts that made her feel impossibly full. “Elena's clit was tiny. Sensitive. One touch and she’d blush for an hour. Yours is swollen, sticking out like it’s begging. Disgusting.”

The orgasm hit like a freight train. Sophia screamed, squirting across the bench, thighs shaking uncontrollably. Marcus didn’t stop the wand. He kept it pressed, forcing her through aftershocks into painful overstimulation.

“Stop—please—I can’t—!”

“You can. You will.” He yanked the plug out suddenly—her hole gaping for a second—then slammed his cock into her ass in one brutal thrust.

Sophia howled. No warm-up, no mercy. Just raw, thick cock splitting her open. He fucked her like he hated her—like he loved her—like he wanted to punish the entire bloodline for daring to deceive him.

“Feel that?” he grunted, hips snapping. “That’s what Elena never gave me. She took it once—cried the whole time. You? You’re clenching like a vice. Milking me.”

“Harder,” she sobbed. “Break me. Make it hurt.”

He did. One hand wrapped around her throat from behind, the other reached under to pinch and twist her clit. His cock pistoned in her ass—deep, punishing strokes that made her see white.

“Say it,” he demanded. “Say you’re glad she’s dead.”

Sophia hesitated—then shattered.

“I’m glad,” she cried. “I’m glad Elena’s gone. I wanted this—wanted you—all of you—the monster under the nice-guy mask. Fuck me like I stole her life. Fuck me like I deserve it.”

Marcus roared—actually roared—and came hard, flooding her ass with pulse after pulse of hot cum. He kept thrusting through it, smearing it deeper, marking her insides.

When he finally pulled out, his seed leaked from her gaping hole, dripping down her thighs. He uncuffed her gently—almost tenderly—then scooped her up and carried her to the bed they now shared.

He laid her on her stomach, ass still leaking, and crawled between her legs. His tongue lapped at the mess he’d made—slow, filthy licks that cleaned her abused hole while she trembled.

“Mine,” he murmured against her skin. “Not Elena’s replacement. Mine. The bad twin. The killer. The whore.”

Sophia buried her face in the pillow, tears mixing with sweat.

“Yes,” she whispered. “Yours.”

But the next morning, when she woke, Marcus was already dressed—dark suit, perfect tie. He looked like the grieving fiancé again. The mask was back on.

“We have brunch with Elena’s parents today,” he said casually. “You’re going to be perfect. Smile. Cry at the right moments. Say how much you miss her.”

Sophia sat up, cum still crusted between her thighs. “And if I slip?”

His smile was ice. “Then tonight I chain you to the cross and invite Rico over. Let him see what became of his missing girlfriend. Let him watch while I fuck every hole you have—while he realizes he lost the better twin.”

Her stomach dropped. Rico. She’d almost forgotten the monster she’d been running from.

Marcus leaned down, kissed her forehead like a lover.

“But you won’t slip. Will you, baby?”

She met his eyes—those cold blue eyes that saw too much.

“No,” she whispered. “I won’t.”

He straightened. “Good girl.”

As he walked out, leaving her alone in the ruined bed, Sophia touched the bruises on her throat, the welts on her ass, the sticky mess between her legs.

She smiled—small, secret, feral.

She wasn’t running anymore.

She was exactly where she belonged.

Brunch was a performance art in hell. Elena's parents—now Sophia's "parents"—sat across the linen-draped table at the upscale café, their faces etched with that perpetual grief-mask people wear after burying a child. Except they hadn't buried Elena; they'd buried Sophia, or so they thought. The irony twisted in her gut like Marcus's cock the night before.

Sophia smiled softly, stirring her mimosa, channeling Elena's quiet grace. "I miss her every day," she said, voice cracking just right. Marcus's hand rested on her thigh under the table—innocent to outsiders, but his fingers dug in, a silent warning.

Elena's mother dabbed her eyes. "You two were inseparable. Like one soul split in two."

Marcus squeezed harder. Sophia bit back a wince. "We were," she agreed. "She was the better half."

Under the table, Marcus's hand slid higher, brushing her panties. No vibe today—just his fingers, teasing the seam. She clenched her jaw, keeping her face serene.

The father cleared his throat. "How are you holding up, Marcus? Planning the wedding without her sister must be hard."

Marcus's smile was perfect—charming, sorrowful. "We're taking it slow. Elena needs time." His finger slipped under the fabric, stroking her clit lightly. Sophia's breath hitched.

"Excuse me," she murmured, standing abruptly. "Bathroom."

In the stall, she leaned against the door, heart racing. Her phone buzzed—Marcus: "Touch yourself. Cum thinking of Rico watching us tonight if you fuck up."

Bastard. But her hand obeyed, circling her swollen nub, imagining Rico's furious eyes as Marcus railed her. She came silently, biting her lip bloody.

Back at the table, she was flawless. No slips. Marcus rewarded her in the car ride home—fingering her to another orgasm while driving, his voice low: "Good whore. Kept the mask on."

Home brought escalation. Marcus led her to the punishment room, but this time, he blindfolded her first. "Trust exercise," he said, voice silk over steel.

He cuffed her to the cross—arms wide, legs spread. Naked, exposed. She heard him rummaging.

"Something new for my impostor." Cold metal clamped her nipples—tight, biting. She gasped. Then a chain connected them, tugging downward.

"Fuck—that hurts."

"Language, Elena." He yanked the chain; pain lanced through her tits. "Sophia talks like trash. Elena doesn't."

A vibrator hummed to life—small, egg-shaped. He taped it to her clit, low setting. Teasing buzz.

"Now, confess more. The dirtiest secret you never told Elena."

Sophia's mind reeled. "I... I fucked her high school boyfriend. Senior year. In her bed while she was at debate club. He said I was tighter, wetter. Came inside me twice."

Marcus's breath hissed. "Jealous twin. Stealing cocks like lives." He turned the vibe higher. Pleasure built, but the nipple clamps distracted—pain anchoring her.

He circled behind, lubing something. "Elena's ass took my finger once. Cried. Yours?" A thick plug—bigger than before—pressed against her hole.

"Wait—too soon after last night—"

"Take it." He pushed, slow but inexorable. She stretched, burned, filled. The vibe ramped up.

"Oh god—Marcus—I'm gonna cum—"

"Not yet." He flogged her back lightly—soft leather strands kissing skin, building to stings. Each strike jolted the plug, the clamps.

"Beg in Elena's voice. Sweet, innocent."

"Please, darling," she whimpered, mimicking her sister's prim tone. "Let me climax. My... my vagina is so needy."

He laughed cruelly. "Vagina? Pathetic." The flogger hit harder, welting her thighs. "Use your words, Sophia. Dirty ones."

"Fuck—let me cum! My cunt's throbbing, ass stuffed, tits on fire—please!"

He ripped the blindfold off, meeting her eyes. "Cum now."

She shattered—body convulsing, squirting around the vibe, ass clenching the plug. Marcus watched, stroking his cock.

"My turn." He uncuffed her, bent her over the bench again. Plug out—replaced by his dick, slick from her mess. He fucked her ass slow this time, savoring.

"Feel how you gape? Elena's stayed tight. Yours is ruined—loose for me."

"More," she moaned. "Deeper. Own it."

He did, pounding until he filled her again, cum dripping out.

After, in bed, he held her—almost gentle. "You're addicted now. To the punishment. To being seen."

She nodded against his chest. "Yes."

The addiction deepened over weeks. Marcus wove the game into everything. Grocery shopping: a butt plug under her skirt, remote-controlled. He'd buzz it in the produce aisle, watching her knees buckle while picking apples.

"Slut," he'd whisper. "Cum in public like the exhibitionist you are."

She did once—hiding behind a display, biting her hand as orgasm ripped through.

At night, roleplay: He'd dress her in Elena's clothes—prim dresses, pearl necklaces. Then defile her.

"Be Elena tonight," he'd command, tying her to the headboard. "Resist me."

"No, Marcus—please—I'm not ready," she'd plead in her sister's voice.

He'd force her legs open anyway, eating her pussy like a starving man. "Taste the difference? Elena was vanilla. You're spice—cum and sin."

His tongue delved deep, lapping her folds, sucking her clit until she broke character: "Fuck—yes—eat my cunt, you psycho!"

Then punishment: He'd flip her, spank her until bruised, then fuck her doggy—hard, claiming.

One night, he upped the ante. "Invite Rico over."

Sophia's blood froze. "What? No—"

"Not for real. Roleplay." He handed her the phone. "Text a burner. Pretend."

But it wasn't pretend. Marcus had Rico's number—hacked or something. She texted: "It's Sophia. Alive. Come see."

Rico arrived furious, pounding the door. Marcus let him in, gun hidden in his waistband.

"You bitch—faked your death?" Rico snarled, eyes raking her.

Marcus stepped in. "She's mine now. Watch."

He shoved Sophia to her knees, cock out. "Suck me while he sees what he lost."

Rico lunged—but Marcus's gun stopped him. "Sit. Watch. Or die."

Sophia deep-throated Marcus, gagging, performing. Rico's face twisted—rage, arousal.

"Fuck her," Rico spat. "She's trash anyway."

Marcus did—bent her over the couch, railing her pussy while Rico watched. "See? She cums for me. Begs for it."

Sophia moaned. "Harder—show him—I'm your whore now."

She came screaming, eyes locked on Rico's. Marcus finished inside her, then kicked Rico out—bruised ego, no more.

After, Marcus cleaned her gently. "You liked it. Being watched."

"Yes," she admitted. "Felt... powerful."

The end came unexpectedly. Months in, Sophia found a pregnancy test positive. Twins' curse? Or blessing.

She told Marcus. His eyes lit—dark joy.

"Our child. Not Elena's."

He fucked her tender that night—no pain, just deep, claiming thrusts. "Mine forever."

Sophia arched, cumming soft. "Yours."

No more running. No more masks. Just them—in the shadows, entwined. The bad twin won.

This was the first book I ever wrote. If you’ve never read Dark Desires, you’re missing the spark that built everything I do now. I wrote it for women and couples who want to taste what they read—to turn pages into touch, words into breath, and fantasy into something real. The messages I still receive from that book remind me why desire is holy.
So go on—treat yourself. It’s more affordable than your next lunch… but it might ruin you for ordinary nights forever.
