The bass was a heartbeat in the floorboards, thrumming up through the desk until Sienna felt it in her teeth. She let her head fall back, eyes closed, and just breathed. The air was thick with spilled beer and perfume and the animal heat of a hundred bodies packed into a space meant for half that number. Her gown had ridden up her thighs the moment she'd sat down, the crimson fabric barely a suggestion of coverage, and she didn't have the energy left to tug it back into place.

Her friends were still out there, somewhere in that churning mass of limbs and strobe lights. Mia had been grinding against some guy with a jawline sharp enough to cut glass, and Dana had been doing shots at the kitchen counter like it was her job. Sienna had slipped away between one song and the next, her temples throbbing, her ears ringing, her lungs begging for air that didn't taste like someone else's sweat.

She'd found the desk in the corner by accident. A rickety thing pushed against the wall, half-hidden behind a tower of empty kegs, the weak yellow cone of a desk lamp casting more shadow than light. Something damp and rough brushed her arm — a wool sweater abandoned on the surface, still clammy from whoever had shed it hours ago. She shoved it aside without opening her eyes.

This was better. Here, in the dark, with the music a dull roar instead of a physical assault, she could pretend she was somewhere else. Somewhere quieter. Somewhere with air conditioning and a bed that wasn't a stranger's floor.

The desk vibrated beneath her, the bass so deep it seemed to move through her bones. She felt it in her bare thighs, in the curve of her spine, in the place between her legs that pulsed in time with the beat. Her body was still humming from the dancing, still loose and warm and pleasantly numb from the two drinks she'd had — enough to take the edge off, not enough to blur her edges completely.

She should go back. Mia would come looking eventually, and Dana would make that joke about her being a grandma who couldn't hang. But the thought of wading back into that crowd made her stomach clench, and she let herself have another minute. Just one more minute of stillness before she put the mask back on.

She watched the dancers through half-lidded eyes. They were a wall of moving flesh, too many bodies pressed too close, faces lost in the dark. The strobe light caught them in fragments — a mouth open mid-laugh, a hand raised in the air, a flash of skin — and then swallowed them whole again. She couldn't pick out Mia's dark hair or Dana's bright yellow dress if she tried. They were just shapes now, churning like something alive and hungry.

The wool sweater brushed her arm again, and she swatted at it without looking. The fabric was damp in a way that made her skin crawl, and she wondered, distantly, if it was sweat or something worse. She shifted on the desk, the edge of it digging into the backs of her thighs, and let her legs swing loosely. The gown rode up another inch. She didn't care anymore.

She was so tired. That was the thing nobody warned you about — how exhausting it was to be the one who laughed loudest, who danced hardest, who made sure everyone else was having a good time even when she wanted to crawl under a table and sleep for a week. She'd been running on fumes for hours, and now the fumes were gone, and she was just a girl on a desk in a dark corner, too drained to move.

The cold hit her like a slap.

It slid up her bare thigh — a hand, she realized with a jolt, a hand that was impossibly cold, like it had been holding ice. It moved with purpose, not groping blindly but tracing a path straight up her leg, over the sensitive skin of her inner thigh, under the hem of her gown.

Her breath caught. Her body went rigid, every muscle locking at once, and for one stupid, frozen second she thought it must be a mistake. A drunk hand from someone stumbling past, a misplaced touch that would retreat as soon as it realized what it had found.

It didn't retreat.

The fingers found the edge of her thong and slipped beneath it, and she felt them — cold and sure and absolutely deliberate — pressing against her, sliding through the slick heat of her, finding her already wet from the dancing and the heat and the press of bodies.

Her heart slammed against her ribs. Her mouth opened, but the sound that came out was swallowed by the bass, a thin gasp that died before it reached her own ears.

She twisted, her hands flying down to grab the wrist, to push it away, to do anything — but the corner was too dark, the press of dancers too thick. She saw shapes, shadows, the glint of sweat on skin, but no face she could name, no hand she could catch. The fingers kept moving inside her, stroking with a rhythm that felt almost practiced, almost kind, and the horror of it was that her body responded before her mind could catch up.

She was wet. She was so wet, and she hated it, hated the way her hips wanted to tilt into the touch, hated the shameful pulse between her legs that had nothing to do with consent and everything to do with biology.

"Stop," she tried to say, but it came out as barely a whisper, lost in the thrum of the music. She pushed off the desk, her palms flat on the surface, her legs swinging to find the floor —

They wouldn't move.

Her legs wouldn't move.

She looked down, and in the weak yellow light of the desk lamp, she saw it. Something cold and hard clamped around her ankle, a band of metal that gleamed dully against her skin. She'd felt it a second ago as pressure, as something wrong, but she hadn't understood. Now she did.

The air left her lungs in a rush. Her hands flew to her ankles, fingers scrabbling at the metal, finding it smooth and unyielding. A cuff. A real cuff, cold against her skin, locked tight enough that she couldn't slide it off, loose enough that it didn't cut off her circulation.

It was connected to something. She followed the line of it with her eyes, saw the chain that ran from the cuff to the leg of the desk, thick and dark and absolutely solid.

Her scream was a bubble in her throat, trapped by the shock. She opened her mouth to try again, to force the sound out, but the music chose that moment to swell — a drop, the bass hitting so hard she felt it in her chest — and her voice was nothing against it. A single note swallowed by a wall of noise.

Behind her, the hand kept moving inside her thong.

It was unbothered by her struggle. Unbothered by the way her body had gone rigid, by the ragged sound of her breathing, by the frantic scrabbling of her fingers against the metal at her ankle. It just kept stroking, two fingers sliding through her slick folds, finding her clit with an accuracy that made her gasp, pressing against it in slow, deliberate circles.

Her hips jerked. Her thighs clenched. She couldn't help it — the touch was too skilled, too knowing, and her body was betraying her second by second, heat coiling in her belly even as terror clawed at her throat.

She twisted again, trying to see who was behind her, but there was nothing — just shadows and the press of dancers, a wall of bodies that had no faces. Whoever it was, they were hidden. They had her cornered in the dark, and no one was looking this way, no one even knew she was here.

The thought hit her like ice water.

No one knew she was here.

She'd slipped away from her friends. She'd chosen the darkest corner of the party, the one spot where the lamp barely reached, where the shadows were deep enough to hide in. She'd made herself invisible, and whoever this was had seen her anyway. Had watched her. Had waited.

The fingers curled inside her, finding a spot that made her whole body seize — a sharp, electric jolt that she felt all the way down to her toes. A sound escaped her, a choked little whimper that she couldn't stop, and the hand seemed to pause, almost like it was savoring it.

Then it moved again. Slower. Deeper. A reward for her body's honesty.

Her hands were still on the cuff at her ankle, her nails digging into the metal, but she'd stopped trying to pull it off. She couldn't think. The music was too loud, the touch too much, the heat between her legs too insistent. She was drowning in sensation, and the worst part was that some small, shameful part of her didn't want to surface.

She bit her lip so hard she tasted blood. The copper tang of it grounded her, just for a second.

She was cuffed. She was trapped. She was being touched by a stranger in the dark, and she was wet, and she was terrified, and she hadn't managed to make a single sound that anyone could hear.

The hand moved faster. Her hips bucked into it, once, twice, and she couldn't stop herself, couldn't stop the way her body was chasing the pleasure even as her mind screamed at her to fight. The bass thrummed through the desk, through her spine, through the place where the stranger's fingers worked her, and she felt her orgasm building like a wave, rising through her, unstoppable.

She didn't know this person. She didn't know their face or their name or what they wanted from her. All she knew was the cold metal around her ankle and the fingers inside her and the dark that pressed in on every side, swallowing her whole.

Her back arched. Her mouth opened. And the scream that tore out of her was lost in the music, a sound no one would ever hear.

The scream died in her throat, and with it went the last of her fight. She sagged against the desk, her palms flat on the surface, her fingers curling into the wood like she could anchor herself to something real. The cuff around her ankle was a cold brand against her skin, and she felt it now with a clarity that cut through the fog of sensation — the bite of the metal, the weight of the chain, the absolute finality of it.

Behind her, the hand slowed. The fingers that had been working her with such practiced precision eased their rhythm, sliding out of her thong with a wet sound that made her stomach turn. She felt the loss of them like a withdrawal, her body still aching for the pressure, still clenching around nothing, and she hated herself for it. The hand retreated, and for one wild, stupid second she thought it was over. That whoever this was had gotten what they wanted and was slipping back into the crowd, leaving her here with nothing but the cuff and the shame.

Then she felt it — a breath against the back of her neck, warm and slow and deliberate. It raised goosebumps along her arms, made the fine hairs on her nape stand up, and she went perfectly still. The breath was close enough that she could feel the heat of it on her skin, close enough that she could smell something on it — cologne, maybe, something dark and woodsy that didn't belong in this sweat-soaked corner. A voice followed, so low it was almost lost in the bass, a murmur that brushed against her ear like a secret.

"Don't scream again."

The words were calm. Almost kind. The kind of voice you'd use to soothe a spooked animal, and something in her chest went cold at the sound of it. She couldn't tell if it was a man or a woman, couldn't tell if it was young or old — it was pitched too low, too careful, stripped of anything that would identify it. It was just a voice, and it was close enough to kiss her.

She didn't scream. She couldn't. Her throat had closed up, her lungs refusing to draw air, and all she could do was sit there on the edge of the desk with her hands gripping the wood and her heart hammering so hard she could feel it in her temples. The breath against her neck moved lower, and she felt lips brush her shoulder — a ghost of a touch, barely there, and then gone.

The hand returned to her thigh. This time it didn't slip under her gown. It just rested there, palm flat against her skin, cold and still and patient. A threat and a promise all at once. And Sienna sat frozen on the desk, her eyes fixed on the dark press of dancers who had no idea she was here, her fingers white-knuckled on the wood, waiting for whatever came next.

She counted the seconds by the pulse in her throat. Ten. Twenty. The hand on her thigh didn't move, just sat there like a brand, and the stillness of it was worse than the touching had been. The touching she could brace against. This — this was waiting. The bass thumped through the desk, through her spine, and she felt every beat in the place where his fingers had been, aching and empty and shamefully wet.

She needed to think. That was the thing. If she could just think, she could find a way out of this, could find the words or the leverage or the moment of distraction that would get her free. But her brain kept short-circuiting, kept sliding off the edge of the situation into a fog of terror and something else, something she didn't want to name.

The hand on her thigh shifted. Just a fraction, the palm rotating until the fingers pointed inward, and she felt the edge of a nail trace a lazy circle on her skin. It was almost gentle. Almost teasing. Like he had all the time in the world.

"Please," she heard herself say, and the word came out smaller than she'd meant it to, a thin and breathy thing. "Please, I won't— I won't scream. Just tell me what you want."

Silence. The music swelled and fell, a wave of sound that crashed over them and receded, and for a moment she thought he wasn't going to answer. Then the hand on her thigh slid higher, and she felt the hem of her gown rucking up, inch by inch, the cool air hitting her skin.

"I want," the voice said, slow and thoughtful, "to see how wet you are."
