Once

It was just supposed to be once. One exciting new thing. Hermione loved taking control and fucking Severus. He allowed her to do it every couple of nights. Soon she was craving something more. She wanted something more exciting.

It was one of her days off and she was sitting in their sitting room trying to read a book. She wasn't really reading. She was staring at the pages.

In the back of her head she was trying to think of something that would be fun to do. Suddenly an idea popped into her head.

Hermione dropped the book and jumped to her feet. She walked into their bedroom and opened the closet. She started pushing boxes around until she came to one marked 'school things'. She grinned opening the box. After a few seconds of digging she pulled out of her school uniform. She hoped that it would still fit.

She lay the outfit down on the bed and stripped herself of her clothes. As she pulled on her old clothes she was relived to see that they fit.

She walked back into the sitting room and from there out into the hallway. She glanced around to make sure no one was coming before she ran the quick distance to Severus' classroom. She knew that he was in there grading papers and she had a big surprise for him.

Hermione knocked on the door.

"Who is it?" Came Severus' tense voice.

"Hermione," she answered.

"Come in babes," he answered.

Hermione opened the door and walked. Severus wasn't looking up. His eyes were on the pile of papers he needed to grade. She closed the door and walked over to his desk.

After a long moment he looked up at her. His eyes widened in surprise.

"What are you doing?" he questioned.

"I'm here for my detention Professor," she said in a soft voice.

Severus just stared at her for the longest time. For a moment Hermione was worried she had crossed some kind of line. Finally Severus nodded and pointed to a desk.

"Sit," he said.

She noticed that he quickly cast a locking and silence spell on the room before he stood up from his desk.

"Do you know why you're here?" he questioned.

"No," she said smiling at him.

"I wouldn't be so happy if I were you," he said snarling at her. "I've had it with your trouble making."

Hermione felt a chill go down her back and for a second she thought he really was mad at her.

"I'm going to let you pick your punishment," he said. "You can either receive ten smacks on your behind or you'll copy lines all night."

Hermione felt her face flush. She had never been smacked before and something about the thought of getting spanked turned her on.

"I'll take the spanking," she answered.

Severus was slightly surprised by her quick answer. He thought she would be a little scared.

"Alright," he said. "Get up, lower your skirt, and bend over my desk."

Hermione stood up and walked over to his desk. She pulled down her skirt with a smirk. She hadn't bothered to put the underwear on.

Severus reached into his desk and when his hand came out he was holding a ruler. Hermione started to panic. She had expected Severus to use his hand.

"Want to change your mind?" he questioned.

"No," she answered as she bent over his desk.

"Good," he said and quickly brought the ruler down on her ass.

"Ah!" she cried clutching the desk.

"How does that feel?" Severus asked smacking her again.

"It hurts Sir!" she cried holding onto the desk.

For second Severus thought about stopping. He didn't really want to hurt Hermione. He decided to keep going. If Hermione really wanted him to stop she would say so.

"It's supposed to," he said hitting her even harder.

"I'm sorry!" she cried. "I'm sorry for every bad thing I did."

"Good," Severus said bringing the ruler down again. "This is only the 4th one. You have a long way to go."

Real tears were leaking out of the corners of Hermione's eyes. Part of her wanted Severus to stop. The other part of her was getting turned on by all this.

"You...deserve...all...of...this," he said hitting her between each word.

Hermione found herself aching her back off the desk. She wasn't trying to get away from the blows. She was trying to get closer to them.

"More!" she cried even as she started to sob from the pain.

Severus stopped counting. He started to lay into her hard with the ruler. Each hit left a red mark on her ass.

"Stop!" she finally cried.

Severus dropped the ruler at once. He was afraid he had really hurt her.

"I need you," she whimpered. "I need you to fuck my ass."

Severus smirked at the fact she had gotten aroused from the spanking. He quickly disrobed and picked up his wand. His cast of lube spell on his cock.

He grabbed hold of her sore ass and spread her cheeks. He slammed into her ass. Hermione cried out at the sudden penetration. Normally it would have hurt her but she was too aroused to feel the pain.

"Do me baby," Hermione cried tears still running down her face. "I need it hard."

That was all Severus needed to hear. He pulled almost all the way out of her before slamming into her. Every time he did it Hermione would arch her back up trying to get more of his cock inside of her.

At first his did this action slowly but quickly he was doing it faster and faster. He knew he wasn't going to last long in her ass.

Within a minute Hermione was cumming harder than she had ever cum in her life. The tightening of her inner walls was too much for her husband. He got in one more thrust before he exploded inside of her.

He rode her for nearly a full minute before he came down from his high. He finally pulled out of her.

"Oh baby," he said helping her stand up. "I hope you get some more kinky ideas."

"I got a million," she said pulling him in for a kiss.
