Detention

Lily squirmed as she bent over her master’s lap. The familiar position brought back too many memories to count. Spanking was one of Master’s favorite punishments… and it was certainly one of HER favorites. Whenever she was bent over her master’s lap, or over a desk, or against the wall, she always got dripping wet. The context didn’t matter. Hell, if he punished her in front of her entire class, she would still become horribly aroused, she was sure. He had practically done that today– and she had been soaking the entire time.

Lily was worried by where Draco was taking this. But she couldn’t help being ten times more excited. Anyway, it was not like she could do anything about it if she wanted to. She couldn’t resist obeying her master now. That was probably the most exciting part of the whole situation.

“Drifting off, are you, girl? Heh, just like in class. Or maybe you’re too focused on your dripping cunt to pay any attention. I suppose I’d better give you something else to focus on.”

SLAP!

His hand struck her bare left cheek with the **** of a charging bull. She screamed, in simultaneous pain and climax. She shuddered, trying to recover from the powerful experience. Her ass was now marked by a deep red handprint, one that she knew she would be feeling for several days.

SLAP!

She had barely had time to recover from her orgasm before his hand struck her other ass cheek, eliciting another scream. Almost another climax, too.

“Alright, that’s enough warming up. Time to get to the real thing.”

Lily did climax again at those words. Hearing that what she had just experienced was just a taste of what was to come… Well, she was quite sure she wasn’t prepared for that.

Draco slid her tiny jean shorts over her ass, it was quite a struggle, given its size, and each tug caused a new flash of pain in her sore asscheeks. When he finally accomplished his task, he revealed her lack of panties. Though that hadn’t been in her original instructions for dressing herself, he hadn’t told her to wear panties either. And somehow, it just felt wrong, wearing anything that he hadn’t told her to. Lucky for her, too. He was already punishing her; she shuddered to think what her punishment would have been if she had panties on, considering his note.

After Draco had pulled her shorts down to her ankles, giving him a good look at her soaking cunt, he started to talk in an authoritative tone. “Not only did you come to class dressed like a whore, Miss Evans, you aren’t even wearing panties! And by the look of your cunt, you must have cum while I’ve been talking to you! This certainly warrants a punishment. I think twenty slaps should do, to start.”

Lily quickly realized that he wanted her to play along. “Oh, I’m so sorry, sir! I swear I didn’t mean to cum in my pants! But being in your lap, with your big, strong hands all over my butt… I just couldn’t help myself, professor.”

“No surprise there. Well, count every slap. If you miss one, we start over. If you cum again, you’ll get another punishment after this. Oh, and thank me each time. You have no idea how much good this discipline is doing you, teaching you your proper place.”

Before Lily could respond, the first SLAP came down on her right ass cheek. “AAHHHHH!” Her scream filled the room, luckily soundproofed. The slap had been at least twice as hard as the ones she had received earlier. Her ass was still jiggling, several seconds later. And it felt so good! Belatedly, she remembered his instructions. “One! Thank you, sir!”

SLAP! “OHHH FUCK! Two! Thank you, sir!” That one felt even better than the first.

SMACK! “AAAOOOHHH GODDDD! MERLIN!” She came furiously, spraying her juices all over her desk and floor. Her Master couldn’t help but notice. What’s more, lost in her climax, she didn’t even manage to count.

Draco laughed. “You’ve orgasmed already, slut? How… disappointing. Yet hardly unexpected. And no count. Very well, I guess we’ll have to restart.” She could do anything but squirm ashamedly in his lap.

So he started again. Each slap was even harder this time. She came again on “TWO!” though she managed to continue the count. When she came on “SEVEN!” she forgot to thank her Master, and so it all restarted again.

It all became a blur of pain and pleasure. She couldn’t say how many times they restarted. Somehow, Draco managed to hit just as hard every time, his arm never getting tired. She also couldn’t say how many times she came. Too many to count. All she knew was that they were all eclipsed by the mindblowing orgasm that washed over her with the final cry of “TWENNNTTTTYYYYY!”

Draco pushed her off his lap, leaving her sprawled on the floor. She didn’t get up. Instead, she was left with a great view of the underside of her desk. Idly, she noticed that someone had carved in a depiction of a naked woman sucking off a troll, and then enchanted it to move. There was no doubt who the woman was, based on her proportions and wavy red locks.

Draco noticed her looking. “Like the drawing? Blaise has always had a talent for drawing, and Theo’s quite handy with animation. We figured it must have happened at some point. There’s no other explanation for your son.” She blushed furiously, but didn’t try to defend Harry. “Well, you can get up off the filthy floor and stop reminiscing about your dear departed husband. You came, way more than I thought even the most depraved slut would, and so it’s time for another punishment.”

Lily trembled, thinking of the intensity of the last one. She shuddered to think what was next. Shakily pushing herself off the floor, she asked, “W-What will my punishment be, sir?”

“I think some lines would teach you a lesson.”

…Lines? That was rather tame. And not sexual. She couldn’t help but feel a flash of disappointment. “What… what do you want me to write, sir?”

Her feelings must have shone through in her tone, because he chuckled, saying “Hoping for something more degrading, slut? Well, since you’re so eager, you can write ‘I’m a dirty Mudblood whore who needs to learn her place’ 200 times on the chalkboard. Oh, and take off that shirt, I want to see your tits.”

Now that was just a bridge too far! She would **** herself, but she refused to **** her fellow muggleborns! She conveniently ignored the times she had done so in the past. Those were different. This time, she… she found herself taking off her shirt, picking up a piece of chalk, and writing the words exactly as he had told her to. She couldn’t help it. Her body simply refused to listen to the commands of her brain. She could not disobey a command from her Master.

But she had never experienced this sensation of not being able to control her body before. That meant that the slavery magic had never before been necessary to make her obey. Whenever she followed a particularly degrading command, she had always mentally passed it off as being **** to do so by magic. Now she knew that wasn’t the case. It had all been her.

She came a little at the thought.

It was no surprise that Draco wouldn’t just stand there while she wrote lines naked, her pert, fat behind presented so enticingly to him. His hands were on her ass before she finished the third line. They took big handfuls of flesh, kneading and squeezing. It hurt– deliciously. She moaned, pushing her ass back into his hands, begging without words for him to continue. And continue he did. Of course, he wasn’t content for long with just groping. Soon, his large, hard dick was out, rubbing all over her ass. Then he was hotdogging her, and every thrust rubbed against her dripping cunt, sending an electrifying shock through her body.

Then, finally, he slipped it in. Well, maybe ‘slipped’ was the wrong word. It was no easy task to fit that monster of a cock into her tight pussy, even as wet as it was. Still, he managed. She came on the spot, of course, her shaky hand making a mess of chalk while she was writing. When he started to thrust, she dropped the chalk altogether, pressing her hands against the board and moaning his name loudly.

“Didn’t I give you a job, slut?!” He demanded angrily. “Can’t even manage a few lines?”

“Sorry, Master!”

She managed to pick up another piece of chalk, continuing her task. There was a clear timeline of Draco’s acts, with the neat handwriting at the top getting shakier and shakier until it became barely legible, with the lines she was currently writing. Still, she wrote, and still, he fucked her.

Every thrust clapped his hips against her ass cheeks, reminding her of the beating he had given her ass. She was quite sure she wouldn’t be able to sit comfortably for a week at least. After fifty lines, she could barely think enough to continue writing. After 100, she only managed to keep standing with her tits pressed against the chalkboard, even as she kept writing. At 150 lines, he suddenly increased his pace to lightning speed. He pounded her cunt like a jackhammer, and it made her cum more than ever.

“Say it, slut,” He growled at her.

She said confusedly, “Wha– what?”

“Say your lines. I want to hear you admit the truth out loud.”

“I– I’m a dirty Mudblood whore who needs to learn her place.”

“Again,” He demanded.

“I’m a dirty Mudblood whore who needs to learn her place!”

“Louder!”

“I’M A DIRTY MUDBLOOD WHORE WHO NEEDS TO LEARN HER PLACE! I’M A DIRTY MUDBLOOD WHORE WHO NEEDS TO LEARN HER PLACE! I’M A DIRTY MUDBLOOD WHORE WHO NEEDS TO LEARN HER PLAAAAAAHHHHHHH FFFFUUUUCCCCKKKK!!!!!!!”

He groaned, filling her cunt with a massive load. If she had been in a more cognizant state, she would have worried about getting pregnant. She was too busy cumming her brains out, though.

Draco stepped away, letting her drop to the floor once again. Her tits were now covered in chalk, her ass was covered in red welts and handprints, her makeup was completely ruined, her cunt was filled with seed, beginning to drip down her leg, and her shorts and panties were still around her uncles, soaked in bodily fluids. She could not have been more fulfilled.

Draco idly waved his wand. “Your little writing activity will stay on the wall overnight, no matter how much you try to erase it. You’d better hope no one comes in here, or else they’ll see you for what you really are.” With that, he casually strolled out of the room.
