The dark room smelled of dust and old wood. Su Xiaorui sat on the edge of her bed, her thighs spilling over the mattress, the cheap fabric of her school uniform straining at the seams. In the mirror across the room—a cracked oval her mother never replaced—she saw the face she hated: moon-round, pocked with acne, eyes too small and too close together, lips perpetually chapped from nervous biting. At sixteen, she had the body of a woman three times her age, breasts heavy and stomach layered, arms thick as hams.
At school they called her "Piggy Sui" or just "the Blimp." Yesterday someone had taped a photo of a walrus to her locker. The day before, three boys had followed her home chanting that she crushed grass just by walking on it. Her mother, Wang Li, never asked about school. She worked double shifts at the garment factory and came home too exhausted to talk. Dinner was often cold noodles left on the counter, or nothing at all.
The source of Su Xiaorui's obsession had come two years ago, during after-school detention. She had been hiding in the hallway bathroom, crying, when the dance teacher, Ms. Fang, entered to fix her hair. Ms. Fang wore open-toed heels, and as she stood at the sink, Su Xiaorui saw her bare feet: slender, arched, toes painted a soft coral. The tendons moved like music when Ms. Fang shifted her weight. Su Xiaorui's breath caught. A hot, strange urgency pooled in her stomach, lower, between her legs. She had never felt anything like it.
From that day, she could not stop. She began collecting images in her mind: every woman's foot she could glimpse. The neighbor Mrs. Chen hanging laundry in flip-flops—her soles were calloused but clean, with a faint earthy smell. The chemistry teacher who wore nylons that sweated. The girl in her class who always wore white canvas sneakers and had long, elegant toes. Su Xiaorui learned their schedules. She would wait in stairwells, crouch behind bushes, memorizing the way each foot stepped, the curve of each arch, the scent wafting up.
The first time she actually touched a woman's foot was six months ago. Mrs. Chen had left her sandals on the doormat while gardening in the back. Su Xiaorui, passing by, felt her body move before her mind could stop it. She knelt, lifted the sandal, pressed her nose to the worn leather. The smell of sweat and leather and dust flooded her. She licked the instep, quick as a snake. Her heart hammered. She put the sandal back, trembling, wetness spreading in her underwear.
After that, she escalated. She stole one of her classmate's ballet flats from the locker room and sniffed it for an hour before returning it. She licked the inside of a stranger's heel print on a bus seat. And then, a week ago, she had done the unthinkable: she waited until her mother fell asleep on the couch, slipped off her shoes and socks, and pressed her face to her mother's feet. The smell was familiar—a little sour, a little salty—and it made her sick with shame and arousal all at once.
Tonight, she had gone further.
Her mother had taken a bath and fallen asleep in her bed, door slightly ajar. Su Xiaorui crept in on all fours. The room was dark except for the streetlamp filtering through the curtain. Her mother's feet hung off the edge of the bed, pale and limp. Su Xiaorui knelt, touched them with her fingers. Her mother stirred but didn't wake. She bent down, her nose brushing the sole. She opened her mouth.
"What are you doing?"
The voice was a whisper, barely audible. Su Xiaorui froze. Her mother was sitting up now, eyes wide in the gloom, hand over her mouth. Wang Li had woken to find her daughter's face at her feet. She saw the lips, the tongue, the ecstatic glaze in those small eyes. Her mind reeled. \*Oh god oh god oh god what is she doing what is she—\*
"Nothing," Su Xiaorui said, scrambling backward. She was already crying.
Wang Li wanted to scream. She wanted to shake her daughter, demand an explanation. But something in Su Xiaorui's posture—the hunch, the desperate shame—stopped her. This was not defiance. This was sickness. And if she screamed, if she showed horror, she might lose her only child to whatever dark hole she had fallen into.
"It's okay," Wang Li said, her voice shaking. "It's okay. Go back to bed."
Su Xiaorui fled. Wang Li sat in the dark, hands trembling, struggling to breathe. She thought about her friend Shen Mengyao, a psychologist who had helped her through a panic attack years ago. Shen Mengyao was calm, smart, married to a kind man named Zhang Wei. She would know what to do.
Two hours later, at 3 a.m., Wang Li called her.
"Mengyao? I'm sorry, I know it's late. I need help. It's about my daughter."
Across town, Shen Mengyao sat up in bed, glancing at her sleeping husband. She stepped into the hallway, her bare feet cold on the tile. "Tell me what happened."
Wang Li's voice cracked as she described finding Su Xiaorui sniffing and licking her feet. She left out the worst details, but the picture was clear enough. Shen Mengyao listened, her professional mind already sorting through possibilities: adolescent fixation, sexual paraphilia, trauma response. It sounded like a classic case of fetishistic disorder, likely rooted in low self-esteem and neglect.
"It might just be a teenage psychological issue," Shen Mengyao said gently. "I've seen similar things. She's experimenting, acting out. It doesn't mean she's broken."
"But what do I do?"
"Bring her to see me. I'll talk to her. No judgment, no pressure. Just a conversation."
Wang Li sobbed with relief. "Thank you. Thank you so much."
Shen Mengyao hung up and stood in the dark, feeling the cold floor under her own feet. She flexed her toes, a strange unease settling in her stomach. She dismissed it. It was just a troubled girl. She would help her. That was her job.
She returned to bed, slipped under the covers, and pressed her feet against her husband's warm legs. He stirred, mumbled something, and wrapped his arm around her. She closed her eyes, unaware that within a week, she would be tied to a chair in that very girl's basement, begging for the foot that would break her.
