The strap bit into her palm as the train swayed, the leather slick with the sweat of a hundred commuters. Lia braced herself, thighs pressed together against the press of bodies, and tried to remember how to breathe. Andrew stood beside her, one hand looped casually through the overhead handle, the picture of a businessman on his way home—except for the hand sliding up her thigh beneath the skirt he'd picked for her that morning. A scrap of black vinyl so short it barely covered her ass, a cropped top that ended above her navel, and a collar that gleamed under the fluorescent lights. He'd dressed her like a streetwalker, and he'd made her watch in the mirror while he did it.

"You're squeezing your thighs together," he murmured, breath hot against her ear. "Everyone can see it, pet. The way you're clenching around nothing."

A flush crawled up her neck. The Lush hummed inside her, a low, constant ache that had been building since they left the brownstone. Since he'd locked it into place and told her she'd wear it until she earned the key again. A week, he'd said. A week of this—of being edged and denied, of serving him on her knees, of wearing whatever he chose to put on her body. A week of being his.

The train lurched and she swayed into him, his chest solid at her shoulder, his cologne cutting through the stale subway air. His fingers found the hem of her thong and hooked under it. She felt the cool air against her skin, then the pad of his middle finger sliding through her folds, slick and unhurried. Her breath caught. The businessman across the aisle turned a page of his newspaper, the paper trembling slightly in his grip.

"Look at him," Andrew said, just loud enough for her to hear. "Pretending to read about the market. You think he can't see the little slut in the vinyl skirt getting wet on my fingers?"

She couldn't look. Her eyes fixed on the ceiling, on the flickering fluorescent lights, on anything that wasn't the stranger's averted gaze. But she felt it—the weight of his attention, the way his knuckles pressed against her inner thigh, the two fingers sliding inside her now, slow and deep, curling against the front wall of her cunt.

She gasped. Quiet, barely a sound, but the businessman's paper stilled for a beat.

"There she is," Andrew said, and there was something like satisfaction in his voice. "You love this, don't you. You dirty little thing."

Lia's jaw tightened. The Lush spiked, a sudden pulse of vibration that made her knees buckle, and she gripped the strap harder to keep herself upright. Her hips twitched forward, pressing into his hand, and she hated herself for it. Hated how good it felt. Hated how much she wanted it.

"Nod," he said. "Tell me you love it."

She shook her head, a tiny, desperate movement. The train rattled over a rough stretch of track, and his fingers pressed deeper, knuckles grinding against her. Her mouth fell open. Her hips rolled.

"Nod," he repeated, softer now, but that softness was worse. That softness was a promise. "And I'll let you come. Tonight. After a week of begging, I'll let you come on my cock."

Her heart slammed against her ribs. The Lush hummed, low and steady, and she could feel the slickness coating his fingers, the wet sound every time he moved. The businessman's paper trembled again. She saw it out of the corner of her eye, the way his knuckles went white around the edges.

She nodded.

"Good girl."

The praise hit her like a shot of heat straight to her core. His thumb found her clit and pressed, and she bit down on her lip so hard she tasted blood. The Lush spiked again, a long, rolling wave of vibration that had her gripping the strap with both hands, her thighs shaking. She was so close. So close—

He pulled his hand away.

The absence was a physical ache, a hollow space between her legs that throbbed with need. She whimpered, a small, desperate sound, and he smiled, slow and dark.

"Not yet, pet. You know the rules."

The train shuddered to a stop. The doors slid open. Andrew gripped her arm and pulled her through the crowd, her heels clicking on the platform, the vinyl skirt riding up with every step. She kept her eyes down, watching his polished shoes as he led her through the press of bodies, past the stairs, past the exit, to a service door unmarked and gray. He pushed it open and she felt the cool draft of air as it swung shut behind them.

She expected stairs. Concrete, darkness, the mineral smell of earth. Instead there was a short corridor, fluorescent lights buzzing overhead, and the unmistakable scent of bleach and damp tile. A public restroom—the kind tucked into the bones of the station for employees, tiled in institutional white, the stalls missing doors, the mirrors streaked with age.

Andrew pushed her inside and the door swung shut behind them, the latch clicking with a sound that made her stomach flip. The Lush hummed. The air was cold on her bare legs.

"Kneel," he said.

Her knees hit the tile before her mind caught up. The shock of it traveled up her spine, sharp and cold, and she felt the grout press into her skin through her stockings. She kept her eyes down, her hands on her thighs, her breath shallow in her chest. She heard him move, felt his shadow fall across her back.

"Look at this place," he said, and his voice was low, almost conversational. "Public restroom. Concrete and bleach and the smell of a thousand strangers." He crouched behind her, his breath warm on the back of her neck. "And here you are, on your knees in it. In the outfit I picked for you. Like you belong here."

She waited. The Lush hummed. His hand found her hair, gathered it at the nape of her neck, and pulled her head back. She looked up at the ceiling, at the fluorescent tube buzzing overhead, and felt his other hand slide down her throat, over her collar, to the hem of her cropped top.

"You think a woman like you deserves anything better?" He tugged the fabric up, exposing her breasts, the black lace of her bra. "Look at you. Obscene body, this desperate little cunt soaking through your thong on a crowded train. You're not a woman. You're a thing I keep. A toy I dress up and use when I want."

His thumb traced the edge of the lace, following the curve of her breast, and she felt herself shiver. The Lush spiked, a sudden pulse that made her hips twitch, and she felt the wetness between her thighs grow, felt it soak through her thong, felt it running down her inner thigh in a slow, warm trickle.

"Speak," he said. "Tell me what you are."

A shudder ran through her. The words were there, waiting on her tongue, the same words she'd said a hundred times before. But here, in this cold, tiled room with the pipes dripping and the fluorescent light buzzing, they felt heavier. More real.

"I'm your slave, Master," she whispered. "Your property. Your—your dumb slave girl."

He made a sound low in his throat, something between approval and hunger. His hand left her hair and she felt his weight shift, heard the slide of his belt through the loops, the clink of the buckle as he drew it free. He stepped closer, the belt hanging loose in his hand, and she felt the leather brush against her cheek, light as a whisper.

"That's right," he said. "My dumb slave girl. So stupid you can't even ask for what you want. So desperate you'd let a stranger watch you fall apart on a train." The belt flexed in his grip. "You should feel honored, pet. Honored that I even bother to use a filthy thing like you."

"Yes, Master." Her voice cracked. "Thank you, Master."

"Thank me for what?"

"For—for using me. For what you're about to do."

He smiled. The belt swung back, and she heard it cut through the air a heartbeat before it landed across her ass, sharp and hot through the vinyl skirt. She gasped, her hands flying to the tile to steady herself, and the Lush spiked, a cruel pulse of vibration that made her hips roll forward.

"Count," he said.

"One," she breathed. "Thank you, Master."

The belt landed again, lower this time, catching the curve of her ass where the skirt had ridden up. The sting bloomed, hot and bright, and she felt her cunt clench around nothing, desperate and empty.

"Two. Thank you, Master."

"You like that, don't you," he said, and the belt cut through the air again. "You like being punished in a dirty public restroom like the whore you are."

"Three. Yes, Master." Her voice was shaking. "Thank you, Master."

The belt landed a fourth time, and she heard herself whimper, her ass burning, her thighs slick with her own wetness. The Lush was still humming, that constant ache, and she felt the pressure building, coiling hot and tight in her belly. She was so close. So close—

"You're not allowed to come," he said, and his voice was hard now, a command that brooked no argument. "Not tonight. Not for a week. You'll beg for it, and I'll keep you right on the edge, and you'll thank me for every second of it."

She nodded, desperate, her forehead pressed to the cool tile. She heard him unbuckle his pants, heard the rustle of fabric, and then his hand was in her hair again, pulling her head back, guiding her mouth to the head of his cock.

"Open," he said. "And thank me for the honor."

She opened. The taste of him hit her tongue, salt and heat, and she heard herself moan around him, her eyes fluttering closed. His hand tightened in her hair, holding her steady, and she took him deeper, her throat working, her hands gripping the tile until her knuckles went white.

"That's it," he said, his voice rough. "Use that stupid mouth. Show me how grateful you are."

She gagged, tears pricking at the corners of her eyes, and he pulled her off with a wet sound, spit stringing from her lips to the head of his cock. He was hard, flushed, leaking against her cheek, and she looked up at him with wide, pleading eyes.

"Please, Master," she whispered. "Please—"

"Please what?" He smeared the head of his cock along her lips, smearing her spit, her lipstick. "Tell me what you want, you dumb thing."

"Please fuck me. Please use me. I need—" Her voice broke. "I need your cock, Master. I need you to breed me."

He made a sound of dark satisfaction. "That's what I wanted to hear." He pulled her up by the hair, turned her around, and bent her over the sink, her palms flat on the cold porcelain, her ass in the air, her skirt rucked up around her waist. She heard him spit, felt his hand between her legs, his fingers sliding through her folds, slick and obscene.

"Look at you," he said, and his voice was full of contempt and hunger. "Dripping like a bitch in heat. In a public restroom. In an outfit I picked out to remind you exactly what you are. You really are nothing but a dirty, nasty little slave, aren't you."

"Yes, Master," she sobbed. "I'm yours. All yours."

He pushed into her in one stroke, and she cried out, her fingers scrabbling on the porcelain, her cunt clenching around him, so full, so deep, the stretch of him burning in the best way. He didn't move. He held still, buried to the hilt, his chest against her back, his breath hot on her ear.

"Feel that?" he said. "Feel how deep I am? This is where you belong. Right here, impaled on my cock, taking everything I give you."

"Yes, Master," she gasped. "Please—"

"Please what?" He pulled out slowly, then slammed back in, and she cried out again, her vision going white. "Please what, you dumb thing?"

"Please don't stop," she begged. "Please fuck me, Master, please—"

He fucked her. Hard, brutal, the sink rattling against the wall with every thrust, the Lush still humming inside her, the sting of the belt still blooming on her ass. She heard herself moaning, wordless, desperate, her cunt clenching around him, her thighs shaking, the pressure building and building until she thought she'd die from it.

"You want to come?" he said, his voice a snarl in her ear. "You want to come on my cock like the little whore you are?"

"Yes, Master," she sobbed. "Please, please, please—"

"Then beg for it." He slowed, just enough to make her ache, his hips grinding against her. "Beg me to fill this dirty cunt. Beg me to breed you."

"Please," she begged, her voice raw, tears streaming down her face. "Please breed me, Master. Please fill me up. I need it. I need your cum, I need—I need you to make me yours—"

He slammed into her, deep, and she felt him swell inside her, felt the hot pulse of his release as he came, filling her, marking her. She sobbed his name, her cunt clenching around him, and the Lush spiked one final time, sending her to the edge—so close, so close—and then it stopped. The vibration cut off, leaving her hanging, trembling, her orgasm just out of reach.

She cried out, a sound of pure frustration, her hips grinding back against him, trying to find the friction she needed. He pulled out, slow, and she felt the cum leaking out of her, running down her inner thigh. He turned her around, his hand on her throat, and looked at her—flushed, tear-streaked, marked with his belt, his cum dripping from between her legs.

"That's what you are," he said, and his voice was quiet now, almost gentle. "My dirty, nasty little slave. And you loved every second of it, didn't you."

She couldn't speak. She nodded, her eyes wide and dazed, her lips parted on a breathless sigh.

"Good girl." He kissed her forehead, a soft, almost tender press of his lips. "Now clean yourself up. We're not done yet."

He stepped back, tucking himself away, and she watched him, her body still trembling, the Lush silent inside her. She reached for the sink, her legs barely holding her, and she heard the door creak open behind him—a maintenance worker, mid-sweep, freezing at the sight of them.

Andrew didn't even look at him. He just smiled, slow and dark, and held out his hand.

"Come, pet. Let's give him something to think about."

She took his hand, her fingers trembling, and let him lead her past the frozen maintenance worker, out of the restroom, into the corridor. The Lush was still silent, but she could feel it waiting, a promise coiled in her core. A week, he'd said. A week of this. A week of being edged and denied, of serving him on her knees, of wearing whatever he chose to put on her body.

She followed him into the dark, her heart pounding, her thighs slick with his cum, and she knew—with a certainty that settled into her bones—that she would beg for every second of it.
