"Drink it, you little loser, or I tell everyone about your little panty stash."
Quinn Hartley held the vial of iridescent liquid to Felix's trembling lips. The nerdy college sophomore had been her convenient dupe for months—running errands, doing her housework, keeping her secrets. Now he would serve the ultimate purpose.
"Mrs. Hartley, please—I don't—gluck"
She forced the Dupli-8 down his throat.
The transformation was immediate and delicious. Felix's skinny frame began to shimmer. He gasped, dropping to his knees as his body rearranged.
"Ooooh, fuck—" The voice was already changing, rising in pitch, becoming breathy and feminine. Felix's shoulders cracked inward, narrowing dramatically as his chest began to swell. Pop. Pop. Pop. Each rib reforming, each bone reshaping.
Quinn watched with wicked delight as breasts blossomed beneath his fading t-shirt—first small mounds, then swelling larger, larger, the fabric straining, stretching, tearing as the new D-cups surged forward, high and firm and fake-perfect on a body built for sin.
"Can't—can't breathe—" The transforming figure clawed at constricting clothes as hips cracked outward, ass inflating with wet, obscene sounds—not soft and pillowy, but tight and muscular, the kind of gym-built bubble butt that bounced just right. Felix's cock didn't just shrink—it melted, pulling inward with a slurping noise, reforming into a tight, wet, perfectly waxed slit between strong, toned thighs.
Hair cascaded down in waves of rich, dark brown, growing inches per second, glossy and thick. Nails lengthened into perfect French tips. Lips plumped up, glossy and swollen. And everywhere—everywhere—the body was cut and defined. Toned abs rippled into existence. Sleek muscle wrapped slender limbs. This was a body sculpted by obsession, by squats and protein shakes and hours staring at oneself in gym mirrors.
And then the eyes opened—her eyes. Icy blue with that permanent look of bratty calculation.
"Oh my god," the new Quinn breathed, running delicate hands over her borrowed body, feeling the firm muscle beneath silky skin. "I'm... I'm you."
"That's right loser," the original gloated, towering over her doppelganger. "For eight hours. And you're going to keep my idiot husband company while I go get properly fucked by a real man."
The copy blinked, Felix's remaining confusion fading as Quinn's memories flooded in—all twenty-four years of being rich, spoiled, and insatiable. Years of gym sessions designed to build the perfect fuckdoll body. Years of affairs.
She remembered Marcus.
"Wait." The copy's eyes narrowed—the same calculating look the original wore. "You want me to entertain Richard while you go fuck Marcus? That personal trainer you've been banging for three months? The one with the massive—"
"I know what he has," Original Quinn snapped.
"So do I." The copy stood, already moving with Quinn's natural predatory grace, her toned legs flexing with each step. "Every thrust. Every orgasm. That man is a god." She licked her lips, running her hands over her defined abs. "And you want to keep him all to yourself? Fuck you bitch."
"How dare you speak to me that way. I'm the original—"
"So what does that matter?" The copy tilted her head, an evil little smirk playing across identical features. "I have all your memories. All your desires. All your needs." One perfectly manicured hand slid down to cup her new pussy. "Mmmmmh. God, I'm wet already just thinking about him. These gym-built thighs want to squeeze around someone."
"Listen here, you little copy—"
"No, you listen." The copy stepped closer, their identical faces inches apart. "Richard's going to be home in twenty minutes. He already suspects something. Why else would you need me?" She grinned. "So here's what's going to happen. You're going to share Marcus with me, or I'm going to tell your husband everything. Show him pictures. Show him texts. I have all your memories, remember? I know where you hide the evidence."
Original Quinn's jaw dropped. "You wouldn't—"
"Try me," smirked the copy. "I'm you, remember? I know exactly how ruthless we can be. Richard is just going to have to go on suspecting we're having an affair. I'm not staying here with that fucking loser."

ONE HOUR LATER
"Damn, baby, you're eager today—"
Marcus's words died in his throat as two Quinn Hartleys crawled onto his hotel bed.
"What the fuck—"
"Surprise, daddy," Original Quinn purred, running her hands up his muscular dark chest. "You always said you wanted more of me."
"I—there's two of you— how?"
"One of us took Dupli-8 and now there are two of us. Mmmmh, but we couldn't decide who gets your cock," Copy Quinn giggled, identical hands sliding down to grip his already-hardening shaft. "So we're gonna share."
"Wait, which one's—" Marcus shook his head, laughing as he took in both women—their matching dark brown hair, their identical toned bodies, those perfect D-cups sitting high on sculpted torsos. "Actually? I don't give a damn."
Original Quinn positioned herself at his mouth while Copy Quinn descended on his cock, swallowing him with expertise born from shared memory. Both women moaned in unison—identical pitches, identical hunger.
"Fuck, his tongue is so good," Original gasped, grinding her firm ass against his face.
"Mmmmph—his cock is even better," Copy slurped, pulling off with an obscene pop. "I want it inside me. Now."
"Get in line, copycat—"
"I've existed for like an hour and I'm already a better fuck than you—"
"Ladies," Marcus growled, grabbing both women by their identical dark hair. "There's plenty of Marcus to go around. But first—" He pulled Original up to his face, kissing her deeply, then did the same to Copy. "You're gonna put on a show for me."
The two Quinns looked at each other.
"Fine," Original huffed. "But I'm on top."

THREE HOURS LATER
The hotel room was a wreck. Sheets tangled. Lamps knocked over. The air thick with sex and sweat and competition.
"My turn with his cock—"
"You just had it—"
"I barely got three minutes—"
"Because you don't know what you're doing, copy—"
"At least I don't sound like a dying whale when I come—"
"Ladies," Marcus laughed, lying back as the two identical women squabbled over his erection. Their toned bodies glistened with sweat, firm muscles flexing as they wrestled. "There's no losers here."
He watched them argue, completely unable to tell which was which anymore. Both had his cum on their faces and tits. Both had that well-fucked glow. Both were fingering themselves as they bickered, unable to stop touching their identical bodies.
"You know what?" Original Quinn suddenly grinned evilly. "Let's ask him. Marcus, baby—which one of us is better?"
Copy Quinn's eyes narrowed. "Oh, that's not fair—"
"Prove you're the real Quinn," Original challenged, her toned body glistening. "Show him what you've got."
"Fine!" Copy turned to Marcus and descended on his cock with renewed vigor, deep-throating him with enthusiasm.
"Oh, you think that's impressive?" Original shoved her copy aside. "Watch this."
Marcus groaned as the two women took turns, each trying to outdo the other. They kissed around his shaft, tongues dueling, neither willing to surrender.
"God, you're both incredible," he moaned, watching their firm, gym-sculpted bodies move.
"I'm more incredible," Original insisted, then gasped as Copy slipped two fingers inside her.
"Prove it," Copy whispered against her ear, her other hand gripping Original's tight, muscular ass.
What followed was a tangle of identical limbs, matching moans, and the wet sounds of two Quinns discovering they were very attracted to themselves.
"I hate you," Original whimpered as Copy's tongue worked her clit.
"No you don't," Copy giggled between licks. "You love this. We love this." Her strong hands gripped Original's thighs. "God, our body is so tight."
And watching from the bed, Marcus smiled.
He still had no idea which was which.
And somehow, that made it so much hotter.
