The ride to Bungalow 4 felt like a funeral procession for his dignity.

Kai pedaled through the freezing fog, his legs burning, but his mind was focused entirely on what he was wearing under his jeans.

He had spent twenty minutes tearing through his drawer at home, panicking, until he found them—a pair of tight, black Calvin Klein boxer briefs he had received as a gift and never worn because they felt too revealing.

But tonight, they weren't underwear. They were a uniform.

She told me to wear them, Kai thought, the wind biting his face. And I did. Like a trained dog.

He reached the house, parked his bike, and walked up the steps. His heart wasn't hammering with fear anymore; it was thudding with a heavy, leaden anticipation. He checked his watch. 6:59 PM.

He pressed the bell.

The door opened instantly.

Anastasia stood there. She wasn't wearing the slip, or the shirt, or the red dress. She was dressed in a sharp, charcoal-grey pencil skirt and a crisp white blouse, buttoned all the way to her throat. She looked like the strict, untouchable authority figure she was in the school corridors. Her hair was pulled back in a severe, tight bun.

She didn't smile. She didn't say hello.

Her eyes dropped immediately to his waist, then back to his face.

"Inside," she commanded, her voice clipped and cold.

Kai stepped in. The warmth of the house hit him, but Anastasia’s demeanor kept the air freezing. She closed the door and locked it—click, thud—then leaned back against it, crossing her arms.

She didn't move to the living room. She stayed right there in the hallway, blocking his exit.

"Did you receive my message, Kai?" she asked, arching an eyebrow.

"Yes, Ma'am," Kai whispered, gripping the strap of his bag.

"And?" she prompted, tapping her foot impatiently on the floor. "Did you follow the instructions? Or do I need to mark you down for insubordination again?"

Kai swallowed. "I... I followed them."

"Prove it," she snapped.

Kai froze. "Here? In the hallway?"

"Did I stutter?" She stepped forward, invading his space, her perfume clouding his senses. "Drop your bag. And then drop your jeans. I want to see if you are capable of following a simple dress code."

Kai let his bag slide to the floor. His hands were shaking as they moved to his belt. It felt insane to be undressing in the hallway, fully clothed in his winter jacket and hoodie, while she watched him like a drill sergeant.

He undid the buckle. The button. The zipper.

He pushed his jeans down to his ankles, stepping out of his shoes to kick them away.

He stood there, shivering slightly, wearing his thick hoodie and the tight, black boxer briefs.

Anastasia’s eyes narrowed as she inspected him.

The black fabric clung to him like a second skin. It left nothing to the imagination. Because of the adrenaline, because of her proximity, and because of the sheer taboo of the command, Kai was already semi-hard. The bulge pressed against the black cotton, stretching it, outlining the thick shape of his cock clearly.

Anastasia walked around him slowly, a shark circling prey.

"Black," she murmured, tracing a finger along the waistband. "Good. It suits you."

She stopped in front of him. She reached out and flicked the front of the boxers, right against the head of his cock.

Kai jumped, gasping. "Ma'am!"

"Sensitive," she noted coolly. "And filling out the uniform quite nicely."

She looked him in the eye, her expression hardening.

"But this is only half the instruction, Kai. I need to inspect the equipment properly."

She pointed to the floor.

"Drop them."

Kai’s breath caught. "Completely?"

"Take them off," she ordered. "I want you naked from the waist down. I want to see exactly what I am working with tonight."

Kai hesitated for only a second. He hooked his thumbs into the waistband of the black boxers. He pushed them down.

His cock sprang free, fully hard now, bobbing in the cool air. It was red and swollen, leaking a clear drop of precum from the tip.

Anastasia didn't look away. She stared at it with a clinical, possessive intensity.

"Look at that," she whispered, a cruel smirk playing on her lips. "Standing at attention for your teacher. You are so eager, aren't you? Leaking like a bitch before I’ve even touched you."

She reached out and wrapped her hand around his hard shaft. Her grip was firm, professional, yet devastatingly erotic. She gave a single, hard squeeze.

"It is throbbing," she observed, feeling the pulse against her palm. "You are desperate to use this, aren't you? You spent all day thinking about putting this inside me."

She let go, leaving his cock swinging and aching for her touch.

"Well," she said, turning on her heel and walking toward the living room, her hips swaying in the pencil skirt. "Come along, Kai. Bring your textbook. Since you are so hard, let's see if you can focus on biology while you sit there... exposed."

She looked back over her shoulder, her eyes gleaming.

"And leave the boxers on the floor. You won't be needing them for the rest of the night."
