The warehouse air was thick with the metallic tang of sweat and something darker, the lingering ghost of the past hours’ exertions. Xiao Jie sat back on the creaking wooden chair, his trousers pooled around his ankles, his semi-hard cock resting against his thigh. Ting Nu—Nan Wanting, though the name felt distant now—knelt before him, her head bowed, her lips wrapped around his shaft with a practiced, hollow tenderness. Her tongue traced lazy circles around the glans, her movements slow, almost reverent, as if she were trying to coax life back into a dying ember. But Xiao Jie’s mind was elsewhere.
His eyes kept drifting to the figure sprawled on the stained mattress a few feet away. Yue Nu—Liu Yueru—lay motionless, her voluptuous body splayed like a discarded doll. Her chest rose and fell in shallow, uneven breaths, and a thin sheen of sweat glistened on her brow. The training had been brutal. The trainer’s commands had pushed her beyond her limits, and when she finally collapsed, it was with a wet, gurgling sigh that sent a chill down Xiao Jie’s spine. He had seen her endure pain before—she seemed to crave it—but this was different. Her eyes had rolled back, her limbs had gone limp, and no amount of slapping or pinching had roused her.
“Ting Nu,” he said, his voice hoarse. “Stop.”
Nan Wanting froze, her lips still wrapped around his cock. She looked up at him, her eyes wide and questioning, a thread of saliva connecting her lower lip to his shaft. She withdrew slowly, wiping her mouth with the back of her hand. “Is something wrong, little master?” Her voice was soft, concerned, the tone of the caring big sister she had once been.
Xiao Jie gestured toward the mattress. “She’s not waking up. I think she’s really out this time.”
Nan Wanting turned her head, her expression shifting from submissive attentiveness to genuine worry. She rose to her feet, her naked body moving with a grace that belied the grime and bruises that marked her skin. She knelt beside Liu Yueru, pressing two fingers to her neck. “Her pulse is steady, but weak. She’s exhausted, maybe more than that.” She looked back at Xiao Jie, her brow furrowed. “We need to get her to a doctor. The trainer wouldn’t want her damaged beyond repair.”
Xiao Jie’s heart hammered against his ribs. He scrambled for his phone, the cracked screen lighting up in the dim warehouse. He had the trainer’s number saved under a single emoji—a crown. He typed with trembling fingers: *Yue Nu passed out. Not waking up. What do I do?*
The reply came almost instantly, as if the trainer had been waiting. *Don’t panic. Stay where you are. I’m sending a special doctor. She will handle everything. Obey her instructions.*
Xiao Jie let out a breath he didn’t realize he’d been holding. He set the phone aside and looked at Nan Wanting. “Trainer says a doctor’s coming. We wait.”
Nan Wanting nodded, settling back onto her knees beside the chair. She reached for his cock again, her fingers brushing the underside. “May I continue, little master? It will help pass the time.”
Xiao Jie hesitated, then nodded. He needed the distraction. He needed to feel in control, even if only in this small way. Nan Wanting leaned forward, her lips parting, and took him into her mouth once more. This time her movements were more deliberate, her tongue working the shaft with a desperate energy, as if she were trying to prove her worth. Xiao Jie closed his eyes, letting the wet heat wash over him, but his mind remained fixed on the unconscious woman beside them.

Across town, in a sleek penthouse that overlooked the city’s glittering skyline, Tan Xin’er stood before a full-length mirror. Her body was a masterpiece of discipline—lean, curved, every muscle defined yet feminine. She had just stripped off her SWAT uniform, the black tactical gear piling at her feet like a shed skin. Now she reached for the nurse’s uniform laid out on the bed.
It was not a standard-issue garment. The dress was a crisp white with a plunging neckline that exposed the swell of her breasts, held in place by a thin red cross stitched over the left cup. The hem barely reached mid-thigh, and the back was cut away entirely, leaving her spine bare. She slipped it on, the fabric cool against her skin, then fastened a white belt around her waist, cinching it tight. She reached for a pair of white thigh-high stockings, rolling them up her long, toned legs, and then strapped on a pair of pristine white heels—seven inches, with a sharp, surgical precision.
From a drawer, she retrieved the restraints: a pair of handcuffs, their metal polished to a mirror finish, and a set of ankle cuffs connected by a short chain that would allow her to walk but not run. She clicked them into place, the cold steel biting into her wrists and ankles. Then she lifted a leather collar from its velvet-lined case. It was black, studded with silver rivets, and from it hung a small metal tag engraved with words: *Beast Doctor Xin Nu.*
She fastened the collar around her neck, feeling the weight settle against her throat. In the mirror, her reflection stared back—a perfect image of submissive professionalism. But her eyes held a glint of something darker, something hungry.
She picked up her medical kit, a black leather bag filled with vials, syringes, and instruments whose purposes were far from healing. Then she grabbed a large suitcase, the kind meant for international travel, its interior lined with foam and straps. She had prepared it earlier, knowing this day would come.
Barefoot now—she had slipped off the heels, preferring the silent tread of bare soles—she descended the stairs to the underground garage. She tossed the suitcase into the trunk of her unmarked sedan, slid into the driver’s seat, and keyed the ignition. The engine purred to life. She pulled out her phone, sent a quick message to the trainer—*En route*—and then set the device aside.
The drive to the warehouse was a blur of streetlights and shadows. She navigated through the industrial district, past abandoned factories and rusted railings, until she spotted the dim glow spilling from the warehouse’s broken windows. She parked a block away, retrieved the suitcase and medical kit, and walked the rest of the way.
Her bare feet made no sound on the gravel. The handcuffs jingled softly with each step, the ankle cuffs clinked a metallic rhythm. She paused at the steel door, took a breath, and pushed it open.

The creak of the door snapped Xiao Jie’s attention away from Nan Wanting’s ministrations. He looked up, and his breath caught in his throat.
A woman stood in the doorway, silhouetted against the pale moonlight. She was tall—taller than he remembered, or maybe it was the heels she wasn’t wearing. The nurse’s uniform clung to her like a second skin, the white fabric almost glowing in the dim light. Her hair was pulled back into a severe bun, but a few strands had escaped, framing her face. Her eyes were sharp, predatory, but softened when they met his.
It was Tan Xin’er. But not the Tan Xin’er he knew—the proud SWAT captain, the star police flower. This woman wore handcuffs. She wore a collar. She had come to him on her knees.
“Little master,” she said, her voice a low, sweet purr. She closed the door behind her, set down the medical kit and suitcase, and then, without a word, dropped to her knees. She crawled forward, the chain of her ankle cuffs scraping against the concrete floor, until she reached Xiao Jie’s feet. Then she pressed her forehead to the ground, kowtowing with a grace that was both submissive and practiced.
Xiao Jie’s semi-hard cock, which had been wilting in Nan Wanting’s mouth, surged back to life. It grew so fast and so thick that Nan Wanting gagged, her eyes watering as she struggled to accommodate the sudden girth. She pulled back, coughing, but Xiao Jie didn’t notice. His eyes were locked on Tan Xin’er.
“Xin’er?” he said, his voice cracking. “What... what are you wearing?”
Tan Xin’er raised her head, her lips curling into a smile. “Beast Doctor Xin Nu, at your service, little master. The trainer sent me to tend to Yue Nu.” She glanced at the unconscious woman on the mattress, then back at Xiao Jie. “Don’t worry. I’ll have her fixed up in no time.”
She rose to her feet, the chain of her ankle cuffs clinking, and walked over to Liu Yueru. Her movements were fluid, deliberate, as if she were performing a ritual. She knelt beside the mattress, opened her medical kit, and withdrew a syringe filled with a pale blue liquid. She tapped it, squirted a thin stream into the air, and then, with the precision of a true professional, injected it into Liu Yueru’s neck.
Liu Yueru’s body jerked once, twice, then went still. Her breathing deepened, became more regular. Tan Xin’er pressed her ear to Liu Yueru’s chest, listening, then nodded. “She’ll be fine. The drug will stabilize her. She just needs rest.” She opened the suitcase, revealing its padded interior. “I’ll take her back to the villa. The trainer has a recovery room there.”
With surprising strength, Tan Xin’er lifted Liu Yueru’s limp body and placed her inside the suitcase. She arranged her limbs carefully, strapped her in place, then closed the lid. The suitcase clicked shut.
Everything was ready. Tan Xin’er turned back to Xiao Jie, crossed the room, and knelt before him once more. She kowtowed again, her forehead touching the floor.
“Little master,” she said, her voice muffled against the concrete. “Please play with Ting Nu, that bitch, for now. When Yue Nu recovers, I will bring her back for you to play with.” She raised her head, turning her face to the side, and her tone shifted. It became sharper, carrying the unmistakable authority of the trainer. “Ting Nu. You are to serve the little master well. Whatever he wants to do with you, you have no right to refuse. Do you understand?”
Nan Wanting, still kneeling with Xiao Jie’s cock in her hand, nodded quickly. “Yes, Beast Doctor. I understand.”
Tan Xin’er smiled, a thin, cruel curve. She kowtowed once more to Xiao Jie. “The trainer lord wishes the little master to have fun.” She rose, grabbed the suitcase by its handle, and began dragging it toward the door. The heavy case thumped over every crack in the floor.
At the threshold, she paused and looked back. Her eyes met Xiao Jie’s, and for a moment, the mask of submission slipped. There was a flash of something else—affection, maybe, or pride. Then she was gone, the door swinging shut behind her.
Xiao Jie sat in the sudden silence, his cock still throbbing in Nan Wanting’s grip. The warehouse felt emptier now, darker. He looked down at the woman kneeling before him, her lips parted, her eyes waiting.
“Ting Nu,” he said, his voice low. “Come here.”
She crawled forward, pressing her face against his thighs. “What do you want, little master?”
He didn’t answer with words. He grabbed her hair, pulled her head back, and thrust his cock into her mouth. She gagged, but she didn’t resist. She took it, all of it, her throat working around him as he fucked her face with a desperate, angry hunger.
Outside, the sound of an engine faded into the night.
