Xiao Tian glanced at the clock on the classroom wall for the third time in as many minutes. Ten-thirty. Two hours left until lunch. His fingers drummed a restless rhythm on the desk, itching for the familiar comfort of his bedroom closet.
The math teacher droned on about quadratic equations, but Xiao Tian's mind had already wandered home. To her bedroom. To the wicker laundry basket she always left half-full by the bathroom door.
His mother, Li Qian, had a habit of kicking off her stockings the moment she walked through the door. She'd shrug off her work suit, toss her pantyhose onto the floor like a shed skin, and pad around the apartment in bare feet. She never noticed when one pair disappeared. Or when it reappeared, neatly folded, buried at the bottom of his own drawer.
He could feel the weight of his phone in his front pocket. The gallery folder labeled "Homework" held over two hundred photos—most of them blurry shots of her calves, her ankles, the curve of her heel trapped in sheer nylon. He'd taken them over the last six months, always careful, always quiet. A snap while she napped on the sofa. A quick capture when she crossed her legs at dinner. The best ones were of her feet in the morning, before she slipped on her pumps, toes flexing against the translucent black fabric.
The bell rang. Xiao Tian blinked, startled, and watched the teacher close her textbook. "Pop quiz postponed to Monday. You're dismissed early—teacher's meeting this afternoon."
A murmur of surprise rippled through the class. Half the students packed up in a hurry, eager for freedom. Xiao Tian remained seated, a strange nervous energy creeping into his chest. Early dismissal meant an empty apartment. His mother wouldn't be home until six.
But maybe he could have a longer session today. Maybe even take a few photos without risking footsteps in the hallway.
He rode the bus home in a daze, the bag on his lap feeling heavier than usual. The autumn sun struggled through grey clouds, casting the streets in a muted, drowsy light. By the time he reached his building, his heartbeat had quickened to the point where he could feel it in his ears.
He inserted the key, turned the lock, and pushed open the door.
Strange. The apartment wasn't quiet.
A muffled sound drifted from the master bedroom. Something between a moan and a whimper, followed by a sharp, rhythmic slapping. Xiao Tian froze, one hand still on the doorknob. His first instinct was to call out—*Mom?*—but his voice stuck in his throat.
He slipped off his shoes and crept down the hallway on socked feet, each step measured, silent. The bedroom door was not fully closed. A sliver of light cut across the dark wood, just wide enough for an eye.
He leaned in.
The world tilted.
His mother, Li Qian, was kneeling on the bed with her hands bound behind her back. Black stockings encased her legs from toe to hip—opaque, glossy, catching the lamplight like polished onyx. Her torso was wrapped in a sheer, transparent black top, the fabric so thin that her nipples pressed against it like dark buttons. Long lace gloves covered her arms to the elbows, and her mouth was gagged with a ball of rolled-up stockings, the ends trailing down her chin. Her eyes were half-closed, unfocused, but there was no fear in them. Only a kind of dazed surrender.
Beside her stood Aunt Li Lin. She was dressed in matching thigh-high stockings—fishnet over nude—and a leather corset that cinched her waist like a second spine. In her hand, she held a small leather paddle. She brought it down against Li Qian's exposed thigh with a sharp, wet crack.
Li Qian's body jerked. Her muffled cry escaped through the gag. But her knees stayed planted, her back arched just a little more.
"Good girl," Aunt Li Lin said, her voice low and approving. "You're taking it so well today. I think you've earned a reward."
She reached down and slowly pulled the gag from Li Qian's mouth. The stockings slid free, wet with saliva. Li Qian gasped, chest heaving, lips trembling.
"Please," she whispered. "More."
Xiao Tian's hand flew to his mouth. His breath came in shallow, ragged bursts. He should look away. He should back up, close the door, pretend he never saw this.
But he couldn't move.
Aunt Li Lin noticed first. Her eyes flickered to the doorway, and a slow smile spread across her lips. She didn't say a word. She just tilted her head, inviting him to stay.
Li Qian followed her sister's gaze. Her face went pale, then flushed crimson. She tried to twist her wrists free, but the bonds held. "Xiao Tian?" Her voice cracked. "No—wait—don't look—"
It was too late. He had already seen everything. And somewhere deep in the cage of his chest, something had broken open—a door he never knew was locked, swinging wide into a dark room he couldn't escape.
