The fluorescent lights buzzed overhead, a sound like trapped flies, and the concrete was cold and gritty against Sienna's knees. She could feel every grain of it pressing into her skin, the sharp edges of the dirt digging in, and she tried to focus on that instead of the man behind her. Instead of the way his hands had clamped onto her hips like he owned them. Instead of the wet, obscene sound of his cock sliding into her from behind, the way her body had betrayed her by being slick enough to take him.

She'd been bent over the hood of a sedan when he'd first pushed her down, her cheek pressed against the cold metal, the smell of oil and exhaust filling her nostrils. Her wrists were bound behind her back with something rough — rope, maybe, or a zip tie — and her ankles were still cuffed together, the chain short enough that she couldn't spread her legs more than a few inches. He'd shoved her gown up around her waist, not even bothering to take it off, and then he'd just… entered her. No warning. No hesitation. Just the blunt head of his cock pressing against her soaked cunt and then pushing in, inch by inch, until she felt him buried to the hilt inside her.

She'd gasped, a choked sound that was half shock and half something else, something she didn't want to name. Her body had clenched around him involuntarily, and he'd let out a low grunt, his fingers digging into her hips hard enough to bruise.

"That's it," he'd said, his voice rough and low, and then he'd started to move.

Now she was on her knees on the concrete, the chain around her ankles keeping her legs together, and he was behind her, one hand tangled in her hair, the other gripping her hip. He was fucking her with a brutal, relentless rhythm, his cock sliding in and out of her wet cunt with a sound that echoed off the silent cars around them. She could feel every inch of him, the way he stretched her, the way he hit a spot deep inside her that made her toes curl even as her mind screamed at her to fight.

She wasn't fighting anymore. She'd tried, at first — pushing back against him, trying to twist away, trying to get her bound hands free. But he was too strong, and every time she struggled, he just tightened his grip and fucked her harder, driving into her so deep she saw stars. Her arms ached from the strain, her shoulders burning, and the concrete was grinding into her knees, but she couldn't move. She couldn't do anything but kneel there and take it.

The fluorescent light above her flickered, a brief stutter of brightness that made her blink, and she caught a glimpse of the garage around her. Rows of silent cars, their paint dull in the harsh light. A tool bench against the far wall, scattered with wrenches and screwdrivers. A security light blinking red in the corner, a small camera pointing at nothing. She was alone here, trapped in this concrete box with a man she couldn't see, and no one was coming to help her.

His breath was hot against the back of her neck, ragged and uneven, and she could smell him now — sweat and something musky, something male. His hand in her hair tightened, yanking her head back, and she let out a strangled gasp as her spine arched, her tits pushing forward, the crimson gown hanging uselessly around her waist.

"Look at you," he muttered, his voice a low growl against her ear. "So fucking wet for me. You were made for this, weren't you?"

She shook her head, a weak, desperate denial, but her body betrayed her. Her cunt clenched around his cock, squeezing him like it didn't want to let him go, and she heard him chuckle, a dark, satisfied sound.

"Liar," he said, and then he pulled out almost all the way, just the head of his cock still inside her, and she felt the loss like a physical ache. She was so full of him, so stretched, and the sudden emptiness made her whimper, a sound she couldn't stop.

"Please," she gasped, not even sure what she was asking for. "Please, I—"

"Please what?" he asked, his voice mocking. "Please don't stop? Please fuck you harder?" He pushed back in, slow and deep, and she felt her eyes roll back in her head. "That's what you want, isn't it? You want me to fuck you until you can't think anymore."

"No," she breathed, but it came out weak, barely a whisper. "No, I don't—"

He cut her off with a thrust, hard enough to knock the breath out of her, and she collapsed forward onto her hands, her bound wrists taking her weight. The concrete scraped her palms, the grit biting into her skin, and she felt him lean over her, his chest pressing against her back, his cock still buried deep inside her.

"You do," he said, his voice right next to her ear. "You want it. You just don't want to admit it."

He started moving again, a punishing rhythm that made her whole body jerk with each thrust. His hips slapped against her ass, the sound sharp and wet in the quiet garage, and she could feel herself getting wetter, her cunt slick and hot around him. It was wrong. All of this was wrong. She was being raped, held down and fucked by a stranger, and her body had no right to respond the way it was. But it was responding. Her nipples were hard, rubbing against the rough fabric of her gown, and there was a heat building low in her belly, a coil of pleasure that she couldn't deny.

He reached around and grabbed her throat, not squeezing, just holding, his fingers pressing against the sides of her neck. "You're going to come for me," he said, his voice flat and certain. "You're going to come on my cock, and then I'm going to keep fucking you until you can't walk."

"No," she sobbed, but it was a lie, and they both knew it.

His thumb found her clit, rubbing in tight circles, and she jerked against him, a gasp torn from her throat. She tried to pull away, but there was nowhere to go, no space to escape. The chain around her ankles was too short, the bindings on her wrists too tight, and he was too strong, too relentless. He was going to make her come, and there was nothing she could do to stop it.

The pleasure was building, cresting, and she hated herself for it. She hated the way her body was responding, the way her cunt was clenching around his cock, desperate for more. She hated the way she was moaning, low and breathy, her hips starting to move with his rhythm, meeting his thrusts instead of fighting them.

"That's it," he grunted, his hand tightening on her throat. "Take it. Take all of it."

She came with a broken cry, her body convulsing around him, her cunt clenching so hard she felt him shudder. He didn't stop. He kept fucking her through it, driving into her as she shook and trembled, her orgasm ripping through her like a wave. She was so sensitive, so overwhelmed, and every thrust was too much, but he didn't care. He just kept going, his rhythm never faltering, his cock sliding in and out of her slick, swollen flesh.

She was barely aware of him pulling out, of the sudden emptiness that made her whimper. She was still trembling, her body limp and spent, and she didn't have the strength to resist when he grabbed her by the hips and flipped her over.

The concrete was cold against her back, the grit digging into her shoulder blades, and she stared up at the flickering fluorescent light, dazed and disoriented. He was a dark shape above her, a silhouette against the harsh glow, and she still couldn't see his face. He was wearing something dark, a hoodie or a jacket, and his features were lost in shadow.

He grabbed her ankles, spreading her legs as wide as the chain would allow, and she felt the cool air on her wet, exposed cunt. She tried to close her legs, but he was too strong, and he just pushed them apart again, his grip bruising.

"You're so fucking pretty like this," he said, his voice low and rough. "Spread open and dripping. You were made for this."

She shook her head, tears leaking from the corners of her eyes. "Please," she whispered. "Please, just let me go. I won't tell anyone. I swear."

He laughed, a cold, humorless sound. "You think I'm going to let you go?" He leaned down, his breath hot against her ear. "We're just getting started."

He positioned himself between her legs, the head of his cock pressing against her entrance, and she felt her body betray her again, her hips tilting up, trying to take him in. She was so wet, so slick, and he slid in easily, filling her completely, and she let out a shuddering breath.

"That's it," he murmured, and then he started to move.

The rhythm was different now, slower, deeper. He was watching her, she could feel his eyes on her face, and she turned her head away, unable to meet his gaze. He reached down and grabbed her chin, forcing her to look at him, but his face was still just a shadow, a dark blur against the light.

"Look at me," he said. "I want to see your face when you come."

She shook her head, a sob catching in her throat. "I can't— I don't—"

"You can," he said, his voice firm. "You will."

He thrust deeper, hitting a spot that made her gasp, and she felt the pleasure building again, faster this time. Her body was learning him, learning the rhythm, and she couldn't stop herself from responding. Her hips moved with his, her cunt clenching around him, and she could hear herself moaning, a low, desperate sound.

He reached down and found her clit again, rubbing it in tight circles, and she came with a strangled cry, her back arching off the concrete, her eyes rolling back in her head. He didn't stop. He kept fucking her, driving into her as she shook and trembled, and she was so lost in the pleasure that she almost didn't notice when he pulled out.

She was still gasping, still trembling, when he grabbed her arm and hauled her up. She stumbled, her bound wrists making it hard to balance, and he pushed her down onto her hands and knees again. The concrete bit into her palms, and she felt him behind her, his hands on her hips, pulling her back against him.

"One more," he said, his voice rough. "Then I'll let you rest."

She didn't believe him. She knew he was lying. But she was too exhausted to fight, too weak to resist, and she just knelt there, her head hanging, waiting for him to take her again.

She felt his cock press against her entrance, and then he pushed in, filling her in one smooth stroke. She gasped, her fingers curling against the concrete, and he started to move, a punishing rhythm that made her whole body jerk.

"That's it," he grunted. "Take it. Take all of it."

She was crying now, silent tears streaming down her face, but she couldn't stop the moans that spilled from her lips. Her body was betraying her, pleasure and pain tangled together, and she didn't know where one ended and the other began.

And then she heard it. A sound that didn't belong. Footsteps. Faint, but unmistakable, the scuff of shoes on concrete, coming from the far end of the garage.

She froze, her heart pounding. "Someone's—" she started, but he cut her off with a thrust, hard enough to knock the breath out of her.

"Shut up," he snarled, his hand clamping over her mouth. "Not a sound."

The footsteps grew closer, and she could hear a voice now, a man's voice, low and muffled. She tried to scream, tried to bite his hand, but he was too strong, his fingers digging into her jaw.

"I said shut up," he hissed, and she felt the cold bite of a blade against her throat.
