The door to B401 slid open with a soft hiss, and Lin Ruojian felt Su Yucang’s hand tighten around hers. They stepped over the threshold together, into a space that should have been familiar—their own home, replicated down to the faded throw pillow on the sofa and the scratch on the coffee table from that night they’d argued and knocked over a wine glass. But the air hummed with the invisible weight of the time-space spell, and the exit door behind them had vanished, replaced by a seamless wall of pale gray.
Lin Ruojian’s breath came shallow. Her silk blouse, pale blue with mother-of-pearl buttons, clung to her skin with a faint chill. She wore it because Su Yucang had once said it made her look like a spring morning, and she needed that memory now, needed something soft against the terror coiling in her stomach. Her skirt brushed her knees, modest and neat, but her hands were trembling.
Su Yucang released her hand and stepped forward. Her dress was black, cut high on the thigh, with a collar that wrapped tight around her throat like a silent command. She held herself straight, chin lifted, but Lin Ruojian saw the way her fingers curled into fists at her sides—the only crack in that cold, proud armor.
“We should change,” Su Yucang said, her voice flat. She turned toward the small rooms along the far wall. “Before they come.”
Lin Ruojian followed, her heels clicking on the polished floor. The makeup room was bright, mirrors framed with soft lights, a vanity stocked with brushes and powders that looked innocent enough. But beside it hung a rack of restraints—leather cuffs with silver buckles, silk ropes in deep red and black, a collar studded with tiny gemstones. Lin Ruojian touched a length of white silk, her fingers tracing its edge. It felt cool and smooth, almost loving.
Su Yucang came up behind her, close enough that Lin Ruojian could feel the warmth radiating from her body. “Don’t think about it yet,” Su Yucang murmured. “Just breathe.”
“I’m trying.” Lin Ruojian’s voice cracked. She turned and buried her face against Su Yucang’s shoulder, breathing in the familiar scent of jasmine and something sharper, like bruised herbs. “What if I can’t—what if I break?”
Su Yucang’s arms wrapped around her, firm and steady. “Then I’ll hold the pieces. But you won’t break, Jian. We’ll take it together. One training at a time.”
A soft chime sounded from the smart system embedded in the wall. A female voice, crisp and professional: “Trainer 001 will arrive in ten minutes. Please prepare.”
Lin Ruojian pulled back, wiping her eyes. She met Su Yucang’s gaze, and in that silent exchange they made a pact: endure, for each other.
They dressed with deliberate care. Su Yucang chose a black leather harness that cupped her breasts and left her back bare, a matching collar with a silver ring at the front. Lin Ruojian helped her fasten the buckles, her fingers lingering on the straps as if she could memorize every inch of Su Yucang’s body this way. Then Lin Ruojian knelt, and Su Yucang tied the white silk rope around her wrists—delicate loops, the ends left long so they could be attached to something later.
“It’s pretty on you,” Su Yucang said softly, her thumb brushing Lin Ruojian’s pulse point. “Like a gift.”
Lin Ruojian bowed her head, a flush rising up her neck. “I’m yours first,” she whispered. “Always.”
The chime sounded again. “Trainer 001 is entering.”
They moved to the center of the room, where a mat of dark blue fabric had been laid out. Side by side, they knelt, knees pressing into the soft padding, and when the door opened, they bent forward in perfect synchronization, foreheads touching the mat.
“Rise,” said the trainer, a tall woman with sharp cheekbones and short-cropped hair, dressed in a crisp white shirt and tailored pants. She carried a leather satchel. Her eyes swept over them with a clinical calm that made Lin Ruojian’s stomach clench.
They straightened, keeping their eyes lowered. The trainer circled them, her boots clicking a slow rhythm. She stopped behind Su Yucang and ran a hand over the bare skin of her shoulder. “You’ll do,” she said. “On your hands and knees, both of you.”
Su Yucang complied instantly, shifting onto her palms and knees, arching her back just slightly—a gesture of submission that Lin Ruojian knew cost her everything. Lin Ruojian mirrored her, her bound wrists making it awkward, the silk rope pulling.
“Pleasant,” the trainer murmured. She opened her satchel and withdrew a prosthetic penis, pale and smooth, with a base designed to be strapped on. She fastened it over her pants with practiced ease. Then she pulled out a condom, tore the wrapper with her teeth, and unrolled it over the prosthetic.
Lin Ruojian’s heart hammered. She watched the trainer’s every movement, the methodical preparation that turned intimacy into procedure. Beside her, Su Yucang’s shoulders were rigid, her breath shallow and controlled.
The trainer knelt behind Su Yucang, one hand on her hip. “I’m going to mark you first,” she said. “Then we’ll see how well you take my pleasure.”
Lin Ruojian’s gaze flickered to Su Yucang’s face, catching a glimpse of her clenched jaw, the way her eyes seemed to focus on a point far beyond this room. She wanted to reach out, to hold her, but her bound hands were useless.
The trainer guided the prosthetic to Su Yucang’s entrance, slow and careful, pressing in with a steady pressure. Su Yucang gasped—a raw, pained sound that tore through Lin Ruojian’s chest. She watched the trainer’s hips move, a rhythm that was almost tender, and Su Yucang’s back muscles quivered with the effort of staying still.
“You’re tight,” the trainer observed. “Good. I like discipline.” She increased her pace, and Su Yucang’s hands fisted in the mat. Lin Ruojian’s mouth went dry. She could see the tears gathering in Su Yucang’s eyes, the way her lips parted on silent breaths.
“Let it happen,” Lin Ruojian whispered, her voice barely audible. “I’m here. I’m watching.”
Su Yucang’s eyes squeezed shut, and a single tear slid down her cheek. The trainer groaned, her rhythm faltering, and then she thrust deeper, holding still as she came, her body shuddering. Lin Ruojian saw the condom fill at the base, a small pouch of white liquid.
The trainer withdrew slowly, tied the condom off, and fastened it to Su Yucang’s collar, the little sac dangling against her collarbone. “There,” she said, her voice satisfied. “Now you’re decorated.”
She stood and retrieved a small stylus from her bag. She knelt before Su Yucang, lifted her chin, and wrote on the skin of her neck—swirling characters that Lin Ruojian couldn’t read. The magic ink glowed for a moment, then sank into the skin, leaving no trace.
“Anytime I say the word,” the trainer murmured, tapping the spot, “it will reappear. Remember that.”
Su Yucang’s gaze was empty, fixed on the floor. The trainer moved to the smart system on the wall and spoke a low message. Then she left without another word. The door clicked shut.
Lin Ruojian shuffled closer on her knees, pressing her bound hands against Su Yucang’s arm. “Cang. Look at me.”
Su Yucang blinked, her focus returning. She turned her head, and the vulnerability in her eyes was so raw that Lin Ruojian’s own tears spilled over.
“I’m still here,” Lin Ruojian said. “We’ll shower. We’ll rest. We’ll do it again.”
Su Yucang took a shaky breath, then reached out and unknotted the silk rope around Lin Ruojian’s wrists. She pressed a kiss to each reddened mark the rope had left. “Together,” she whispered.
They rose, leaning on each other, and walked toward the small bathroom. The day stretched before them, hours of unknown trainers and unseen marks, but for now there was hot water and the quiet comfort of each other’s presence. And that was enough.
