Chapter 125: My student owns my hole -3

Riven found Professor Emrys alone in the empty lecture hall later that same afternoon.

The last students had already left. Emrys stood at the podium packing his notes when the door opened and closed again.

Riven turned the lock with a clear click, then walked to the second exit and locked that one as well.

The sound of both bolts sliding into place made Emrys look up.

"What are you doing?"

Riven crossed the room without hurry.

"Strip. Everything off. Right now."

Emrys glanced toward the locked doors. His voice stayed low.

"Someone could still try the handle."

"They will find it locked. Strip."

The older man set the papers down. His fingers worked the buttons of his shirt first. The fabric opened and slid from his shoulders.

He unbuckled his belt, pushed his trousers and briefs down together, and stepped out of them. Socks followed.

He stood bare in the middle of the classroom while the late afternoon light cut across the desks. His cock hung soft between his legs.

Riven stopped in front of him and looked down.

"You are soft. That means you touched yourself after I left. You came without my permission."

Emrys shook his head at once. "I did not. I went straight to my next class. I kept my hands off. I stayed hard the entire time like you ordered, but I never touched it."

Riven reached out and cupped the soft cock and balls in one firm hand. He gave a slow squeeze.

"I do not believe you. You looked too calm when I walked in. Soft means you took care of it on your own. That is against the rule I gave you."

"I swear I did not," Emrys said. His voice carried a clear edge of desperation. "I followed every word."

Riven released him and stepped back.

"The punishment stays the same either way. Tomorrow morning you will buy a butt plug. Nothing shorter than six inches. You will insert it before you leave for campus. You will wear it through every lecture you teach. Since you are unable to stay hard for me, it will keep pressure on your prostate so you stay hard all day. That is what happens when you break my order."

Emrys’s throat moved as he swallowed. "A six-inch plug. During class."

"Yes. And you will not remove it until I say so. Clear?"

"Clear."

Riven walked a slow circle around the naked professor.

"Get dressed. Go home. Buy exactly what I told you. There will be punishment if you choose something smaller."

Emrys pulled his clothes back on with unsteady hands. Riven unlocked both doors and left without another word.

The older man stood alone in the quiet hall for a long moment before he gathered his things and walked out.

The next morning Emrys stood in his bathroom and stared at the black silicone plug he had purchased the evening before.

The shaft measured a full six inches with a tapered head and a flared base. He coated it with lube, braced one hand on the sink, and pushed it inside himself with slow, steady pressure.

The thick length stretched him open until the base settled flush against his skin.

The moment it seated fully his cock began to fill. Every small shift of his hips sent a deep ache through his prostate.

He dressed carefully. The plug made sitting in the car a constant distraction. By the time he reached campus his cock pressed hard against the front of his trousers.

He walked the hallway with shorter steps than usual. The thick shaft inside him shifted with every movement and kept him fully erect.

He entered the lecture hall and felt Riven’s eyes on him at once. The student sat in the back row again.

Emrys set his notes on the podium and began the class. Each time he turned or stepped to the side the plug pressed deeper.

His voice stayed even, but a fine sweat gathered at his hairline. When he walked the aisle to distribute handouts the movement forced the toy against his prostate in a steady rhythm.

His cock leaked steadily inside his briefs.

Riven watched every step. When Emrys passed the back row the younger man spoke in a voice too low for anyone else to hear.

"Six inches looks good on you, Professor. I can tell by the way you walk. Stay hard for me."

Emrys returned to the front without answering. The rest of the lecture passed in a haze of constant pressure and denied need. By the time he dismissed the class his thighs felt tight and his cock ached.

Riven waited until the room emptied, then looked toward the back. "Your office. Now."

He followed him down the hall. Once the office door locked behind them Riven pointed at the desk.

"Bend over. Chest on your table. Pants and briefs down to your knees."

Emrys obeyed. He draped himself across the desk and pushed the clothing down.

The flared base of the plug sat exposed between his cheeks. Riven stepped behind him and rested both hands on the older man’s ass.

He gripped the base and twisted it slowly in a full circle. Emrys groaned into the desk as the thick shaft turned inside him.

"You wore it the entire time," Riven said. "Good. I watched you struggle to walk normally. I watched the front of your pants stay tented. You followed the punishment."

He pulled the plug out in one long, steady motion. The sudden emptiness made Emrys clench around nothing.

A thin trail of lube followed the toy. Riven set the plug on the desk and spread the older man’s cheeks with both thumbs.

"Look at that hole. Stretched and shiny. You kept my plug warm all morning."

Emrys stayed bent over, breathing hard. His cock hung heavy and dark between his legs, still fully hard from hours of constant stimulation. Riven dragged one finger around the loose rim but did not push inside.

"You are not getting fucked today either," Riven said. "You are going to stay like this for a minute so I can look at what the plug did to you. Then you will pull your clothes up and go to your next class still hard and empty. Tonight I will text you the next instruction. Until then you do not touch yourself. Clear?"

"Clear," Emrys answered. His voice sounded rough.

Riven stepped back and wiped his fingers on a tissue from the desk. "Stand up. Get dressed. Since you have been a good boy, you can leave the plug for now. I will decide when you wear it again."

Emrys pushed off the desk and pulled his trousers back into place. The absence of the thick shaft left him aching in a different way.

He fastened his belt with hands that still trembled slightly. Riven sat in the chair behind the desk as if it belonged to him and watched the older man finish.

"You did well today," Riven said. "Keep obeying and I might let you come the next time I have you bent over this desk. Disobey again and the plug stays in longer."

Emrys nodded once. He left the office with his cock still hard and the memory of the six-inch toy sitting heavy in his mind.

The hallway felt too bright and too ordinary after what had just happened.

He already knew the rest of the day would pass in the same state of denied need that Riven had created.

Emrys understood that the control would only tighten from here.
