Chapter 15: The Challenge
The Amethyst Group’s private lounge felt like the inside of a jewel box, all deep velvets and muted, amber light. Rio moved through it like a ghost, the remnant ache between her legs a persistent, private throb. Every step, every shift in her tailored skirt, reminded her of the plug, of Agatha’s whispered claim. She clutched a crystal glass of something sparkling and untouched, her knuckles white.
The other associates—bright, chattering things from London and Hong Kong—blurred into the background. Her eyes scanned the room, finding Agartha deep in conversation with a silver-haired man by the fireplace. She was a portrait of effortless command, laughing softly, a hand resting on the man’s arm. She hadn’t looked at Rio once.
“You look like you’re trying to solve a constitutional crisis.”
The voice was a warm, smooth contralto, right at Rio’s shoulder. She turned to find Isabella Rossi leaning against the mahogany paneling, a half-smile on her lips. Izzy was Agatha’s opposite: softer curves, warm brown eyes, dark hair falling in careless waves. She wore a burgundy dress that looked painted on.
“Just… taking it all in,” Rio managed, forcing a sip from her glass.
“Bullshit,” Izzy said, her smile widening. “You look like you’re plotting an escape. Or waiting for a signal.” She stepped closer. The scent of her—bergamot and something inherently feminine—wrapped around Rio. “Agatha’s new protégé. Rio, right? The talk of the summer program.”
Rio felt a flush climb her neck. “I doubt that.”
“Oh, you are.” Izzy’s gaze dropped, lingering on Rio’s mouth, then lower, as if she could see straight through the silk blouse to the mark beneath. “Rumors fly in places like this. They say she’s taken a special interest.” Her voice dropped to a conspiratorial murmur. “They say she breaks her toys quickly. Or keeps them forever.”
Before Rio could form a retort, Izzy’s hand was on her arm, gentle but firm, steering her away from the main group towards a shadowed alcove lined with shelves of rare spirits. The noise of the lounge faded into a dull hum.
“I have a theory,” Izzy whispered, her body now a casual barrier between Rio and the room. “I think the rumors are only half the story. I think there’s a fire behind those sharp eyes of yours. I think you like the breaking.”
Rio’s breath hitched. “You don’t know anything.”
“Don’t I?” Izzy’s other hand came up, resting lightly on Rio’s waist. Her thumb stroked a slow, deliberate circle through the thin silk. “You’re trembling. And not from fear.”
It was true. A treacherous heat was uncoiling in Rio’s belly, a direct response to the confident touch, the illicit closeness. This was different from Agatha’s calculated dominance. This was a seduction. It was dangerous.
Izzy leaned in, her lips brushing the shell of Rio’s ear. Her nails dug in, just enough to pinch. “Let’s test those rumors for me, sweet thing.”
In one fluid motion, Izzy spun her, pressing Rio’s back against the cool, flocked wallpaper. The move was shockingly strong. Rio’s glass slipped from her hand, thudding softly on the carpet. Izzy’s knee pressed between her thighs, holding her in place. The sudden pressure against the plug made Rio gasp.
“See?” Izzy murmured, her face inches away. Her eyes were dark with intent. “You’re already wet for it. I can smell you.” Her hand slid down from Rio’s waist, over the curve of her hip, under the hem of her skirt. Her fingers danced along the top of Rio’s stocking. “Let’s see what she’s left you with.”
Rio couldn’t speak. Her mind screamed a warning, but her body arched into the touch, a traitorous offering. Izzy’s fingers slid higher, past the lace of the stocking, onto bare, quivering skin. They found the soaked silk of Rio’s panties—the only garment she herself had put on—and a low, approving sound rumbled in Izzy’s throat.
“Fucking dripping,” she breathed, and hooked her fingers into the side seam, tearing the silk with a brutal, efficient rip.
The cold air of the lounge hit Rio’s exposed cunt. Izzy didn’t hesitate. She slid two fingers through the slick folds, a rough, claiming stroke that made Rio jolt. Then, without preamble, she thrust them inside.
It was a brutal, full sensation. Different from Agatha’s clinical precision. This was hungry, opportunistic. Izzy’s fingers curled, pumping deep, her palm grinding against Rio’s clit with each thrust. Rio’s head thumped back against the wall, a choked whimper escaping her lips. Her hips rocked involuntarily, fucking herself on Izzy’s hand. The shame was molten, mixed with a blinding, urgent need.
“That’s it,” Izzy coaxed, her breath hot on Rio’s throat. “Fuck my fingers. Show me how much of a greedy little slut you are for any woman who wants you.”
The words, so crude and true, sent a shockwave through Rio. She was close, so close, the coil tightening in her gut, the plug amplifying every movement—
Crack.
The sound was a whip-snap of leather on flesh. Izzy yelped, a sharp, pained sound, and her hand wrenched out of Rio so violently it burned.
Agatha stood there, a silhouette carved from shadow and fury. In her hand, a short, rigid riding crop. Her eyes were black ice.
“Did I say,” Agatha’s voice cut through the heavy air, low and deadly calm, “you could touch my property?”
Izzy cradled her wrist, already blossoming with an angry red welt. “Agatha, Christ, I was just—”
“You were just stealing.” Agatha took a step forward. The aura around her wasn’t anger; it was possession, pure and terrifying. She didn’t even look at Rio, trembling and exposed against the wall. Her entire focus was on Izzy, who had shrunk back. “You saw something I polished. Something I trained. And you thought you could get a taste without asking.”
Izzy’s defiance flickered and died. “It was just fun.”
“Your fun is over.” Agatha’s gaze finally flicked to Rio. Her eyes raked over her—the torn underwear, the glistening evidence of Izzy’s intrusion on her inner thighs, the utterly ruined expression on her face. Something in Agatha’s jaw tightened. “Fix your clothes.”
Rio fumbled, her hands shaking too badly to pull her skirt down properly. Agatha watched, her expression unreadable, until Izzy tried to sidle away.
“I didn’t dismiss you,” Agatha said, the crop tapping lightly against her own thigh. “You will apologize. To me.”
Izzy swallowed, her pride visibly crumbling. “I apologize, Agatha. It won’t happen again.”
“It certainly won’t.” Agatha finally turned her back on Izzy, a supreme dismissal. She closed the distance to Rio in two strides. Up close, Rio could smell the cold night air on her leather jacket, see the flecks of gold in her furious eyes. Agatha’s hand came up, not to strike, but to cup Rio’s cheek. Her thumb stroked away a tear Rio hadn’t realized had fallen. Her voice dropped to a whisper only Rio could hear.
“You come when I allow it. You get fucked when I permit it.” Her thumb pressed against Rio’s lower lip. “This bratty streak of yours… letting another woman think she can claim what’s mine… it needs correcting.”
She withdrew her hand, leaving Rio cold. She addressed the room, her voice once again the clear, commanding tone of a CEO. “The evening is concluded. My associate and I have urgent business to attend to.”
Without another glance at the stunned onlookers or a cowed Izzy, Agatha took Rio’s elbow in a grip that brooked no argument and guided her, stumbling, from the lounge. The last thing Rio saw was the shattered crystal of her dropped glass, winking in the dim light like a fallen star, as Agatha led her away into the dark, waiting hall. The only sound was the sharp, decisive click of Agatha’s heels on the marble floor, each one a metronome counting down to a punishment Rio both dreaded and, in the deepest, most secret part of herself, desperately wanted.
The only sound was the sharp, decisive click of Agatha’s heels on the marble floor, each one a metronome counting down to a punishment Rio both dreaded and, in the deepest, most secret part of herself, desperately wanted. They did not speak in the elevator descending to the garage. Agatha’s silence was a physical force, a wall of pure, furious disappointment that left Rio shivering in her torn clothes. The pristine leather interior of Agatha’s town car smelled of cold, distilled air and her perfume, a scent that now felt accusatory.
Rio stared out the window at the blurring Parisian lights, her thighs stuck together with a mix of her own arousal and shame. She could still feel the phantom intrusion of Izzy’s fingers, the violent emptiness when they were pulled away. Agatha’s gloved hands rested calmly in her lap. She never looked at Rio once during the drive. The silence was a greater humiliation than any words could have been.
Agatha’s penthouse was not dark. Every light was ablaze, turning the vast space into a sterile, exposed stage. The terrace doors were closed, the city now a distant, untouchable panorama. “Stand there,” Agatha said, her voice devoid of its earlier warmth, pointing to the center of the living room rug. She shrugged off her leather jacket, placing it and the riding crop on a chair with ritualistic care.
Rio obeyed, her body thrumming with a nervous energy. She watched, heart hammering, as Agatha opened a sleek cabinet, revealing an array of tools that gleamed under the recessed lights. She selected a few, laying them on a low table: a thin, flexible cane, a set of silver clamps connected by a fine chain, a smooth, obsidian wand. Each object landed with a soft, definitive tap.
“You presented yourself as available,” Agatha stated, finally turning to face her. She began to circle Rio, a predator assessing. “You let another woman’s hands on you. You came to the edge on her command.” She stopped behind Rio, her breath warm on her neck. “You displayed my property without my consent.”
“I didn’t—” Rio started, her voice a dry crackle.
Agatha’s hand snaked around, clamping over Rio’s mouth, cutting her off. “You did.” Her other hand found the zpper of Rio’s skirt, yanking it down unceremoniously. The garment pooled at her feet. The torn silk of her panties followed. “You were wet for her. I felt it. You were ready to come for a stranger in a hallway.” She released Rio’s mouth, only to grab a handful of her short hair, forcing her head back. “That earns a punishment. Say you understand.”
Rio’s scalp stung. “I understand.”
“Louder.”
“I understand!” The words were a gasp.
Agatha released her. “On your knees. Face the couch. Ass in the air. I want to see the jewel I placed in you. I want to see it gleam while you learn.”
Trembling, Rio assumed the position, her cheek pressed against the cool, dark velvet of the sofa, her back arched painfully. The open air on her exposed skin was a vulnerability that made her want to fold in on herself. She heard the soft shush of Agatha’s trousers as she knelt behind her.
A cold, lubricated finger traced the rim of her ass, circling the base of the plug already seated there. “She didn’t even notice this, did she?” Agatha murmured, a dark amusement in her tone. “Too focused on your cunt.” She pulled the plug out slowly, stretching the sensitive ring of muscle, then pushed it back in with a firm, relentless pressure. Rio cried out, her fists clenching in the velvet. “This is mine. What’s inside it is mine. Everything that leaks from you is mine.”
The plug was removed and set aside with a soft clink. Then Rio heard the unmistakable sound of the cane being lifted. “Count,” Agatha commanded.
The first strike was a line of pure, shocking fire across the crests of both ass cheeks. Rio jerked, a scream trapped in her throat. “One!” she choked out.
The second landed lower, a parallel brand that made her legs buckle. “Two!”
The third cut across the tender undercurve, and a sob broke loose. “Three!”
Agatha paused. Rio heard her own ragged breaths, felt the throbbing heat building in stripes across her skin. A single finger slid through her soaked folds from behind. “You’re dripping onto the rug,” Agatha observed, her voice flat. “You enjoy this. You’re a greedy, punishable little thing.”
The caning resumed. Four. Five. Six. Each strike was measured, precise, lighting a new path of pain that sank deep and then melted into a strange, pooling warmth in her core. By ten, Rio’s voice was hoarse, her body trembling uncontrollably, her cunt aching and empty and desperately wet.
The cane was set down. Cool metal touched the inside of her thigh—the silver clamps. Agatha attached the first to the delicate skin of her labia, the bite sharp and instantaneous. Rio yelped, her back bowing. The second clamp found her other lip, the pain doubling, focusing into a bright, terrible point. A gentle tug on the chain connecting them sent a shockwave straight to her clit.
“Up,” Agatha ordered, pulling her to her feet by the chain. Rio stumbled, the movement making the clamps bite deeper. Agatha guided her to a full-length mirror. “Look.”
Rio forced her eyes open. Her reflection was a mess of flushed skin, red stripes, and silver metal glinting from between her thighs. Her face was streaked with tears and mascara, her lips swollen from biting them. Agatha stood behind her, fully clothed, a portrait of controlled power. She wrapped a hand in Rio’s hair again and pulled her head back against her shoulder. Her other hand snaked between Rio’s legs, fingers finding her clit, swollen and exposed.
“You want to come,” Agatha stated, fingering the chain, making the clamps jiggle and pinch.
“Yes,” Rio whimpered, humiliated by the truth.
“No.” The finger on her clit began to move in hard, rapid circles. It was not gentle. It was a brutal, efficient friction. Rio’s hips bucked, her breath coming in short, desperate gasps. The pain from the caning, the bite of the clamps, fused with the intense stimulation, driving her rapidly toward the edge.
Just as the coil of her orgasm tightened to the breaking point, Agatha stopped. She removed her hand entirely. Rio whined, a pathetic, animal sound of need, her body trembling on the precipice.
“You don’t get to come,” Agatha whispered into her ear. “You get to feel the want. You get to hold it.” She guided Rio’s own hand down between her legs. “Feel how swollen you are. Feel how much you need it. That ache is your punishment. That is the consequence of offering what is mine to others.”
Agatha then gently, almost tenderly, removed the clamps. The flood of sensation as blood rushed back was a new kind of agony. Rio sagged against her. Agatha held her up, turning her face for a deep, possessive kiss. Rio could taste her own tears.
Leading her to the vast bed, Agatha finally undressed herself with slow, deliberate movements. She pushed Rio onto her back. She didn’t enter her with fingers or a toy. Instead, she lowered her mouth to Rio’s throbbing cunt.
Her tongue was a flat, demanding pressure, licking up the mess of Rio’s arousal and pain with crude, hungry strokes. She fucked Rio with her tongue, deep and rough, then focused on her clit, sucking it hard into her mouth. Rio’s hands flew to Agatha’s head, her back arching clear off the bed. The orgasm Agatha had denied her now rushed forward, unstoppable, a tidal wave breaking from the depths of her punishment.
“Come,” Agatha growled against her, the vibration tipping Rio over.
Rio shattered. It was a violent, whole-body convulsion, a silent scream tearing from her lungs as white light flashed behind her eyes. Wave after wave crashed through her, milking every drop of pleasure from the pain. As the tremors subsided, Agatha rose over her, her own need evident. She guided Rio’s shaking hand between her legs, pressed her fingers into her own wetness.
“Clean your mess from me,” Agatha commanded, her voice ragged. Rio, mindless and obedient, did as she was told, bringing her slick fingers to her own mouth. The taste of Agatha mixed with the salt of her own skin was the final, degrading truth.
Agatha watched her, her eyes dark with satisfaction. She leaned down, kissed Rio’s forehead with a chilling softness. Then she reached for the jeweled plug, still glistening on the table. Without a word, she pushed it back inside Rio, who was too spent to even flinch.
“Sleep,” Agatha said, turning off the light, leaving Rio in the dark, stuffed full, every nerve alight, and utterly, completely owned.
