You wake up the next morning to sunlight streaking through the window. It's a Saturday, so you don't have to hurry out of bed. You glance over towards Hermione's bed and see that it is empty. You sigh with relief as you were not ready to talk to her yet.

You decide to throw on some clothes quickly and head down to get some breakfast. You grab some jeans and a hoodie from your trunk, and are just finishing putting you shoes on when the door opens and Hermione walks in. She sees you looking at her and appears slightly awkward.

"Good morning y/n," she says. "We need to go to Hogsmeade, there's a meeting."

"A meeting, what's it about?" you ask.

"Just grab your coat, we'll explain on the way," says Hermione.

When you go downstairs into the Gryffindor common room you see Harry and Ron waiting for you. Soon the four of you have left the castle and are walking towards Hogsmeade together.

"So what's going on?" you ask.

"We've been talking. We need someone to teach defense against the dark arts, and we think Harry is the person to do it," says Hermione.

"But it's mad, who would want to be taught by me," says Harry. "Everyone thinks I'm a nutter."

Hermione leads the way to a door. "This is the place," she says. "I thought we should use somewhere quiet."

You all go inside the empty room and wait. Before long more of the other children start to join you. Soon the small room is full and it's time for the meeting to start. Hermione stands up awkwardly and starts to speak.

"Umm, so, we all know why we're here," she says. "We need a proper teacher. Someone who has experience defending themselves against the dark arts."

Everyone looks around uncertainly.

"Is it true you can produce a patronus charm?" asks Luna.

"Yes, he can, I've seen it," says Hermione.

"And he killed a basilisk," says Neville.

"Yes, that all sounds good," says Harry. "But you don't know what it feels like when it happens in real life."

"You're right, we don't," says Hermione. "That's why we need you to teach us."

Around the room the other children murmur and nod with approval. Then one by one they come forward and sign up to join Dumbledore's Army.

With the meeting now over, you all head back to Hogwarts.

"Right, first we need to find somewhere to practice without Umbridge finding out," says Harry. "So let's all split up and see if we can find somewhere suitable."

You all nod in agreement, and when you reach the castle entrance everyone heads off in different directions.

You are not really sure where to start as you don't know the castle that well. You decide to head up to the third floor corridor and start opening doors at random to see what is behind them.
You find a couple of storage cupboards first, full of mops and other cleaning materials. Next door you open is the History of Magic classroom, so that's no good.

You try another door and find another empty classroom, but this one has sheets over the desks and looks like it has been unused for a while. Maybe this would work, you think. You head inside the room to take a closer look around.

You are just pulling the sheet off of the teacher's desk at the front when you hear a noise behind you. When you spin round you see Draco standing in the doorway. He looks at you and smirks.

"Look what I've found," he says. "A mudblood snooping around and acting suspiciously."

"Malfoy, I..I..was just..." you say.

"Ma-Malfoy, I wa-wa-..." says Draco mockingly.

He steps into the room menacingly and closes the door behind him.

"What are you doing, mudblood?" Draco asks.

"I was just looking for, umm, somewhere to do, umm, something," you say.

"Well, it looks like you found one," says Draco with a smirk. "This looks like a good place to do something."

Draco pulls out his wand and walks up to you.

"Bend over the desk," he says.

"What?" you say.

"The desk, behind you. Bend over it," say Draco with a mean look in his eyes. "And I don't want to repeat myself again. Do exactly what I tell you or you will get hurt."

You quickly turn around and bend over so your elbows are on the desk. The way Draco is looking at you makes you too scared to resist him.

"Now pull down your jeans," he commands.

You reach under your belly to undo the buttons, then slide your jeans down over your hips.

"Pull down your panties too," he says.

You tremble slightly, then you reach back and pull your panties down to your knees as well. You are scared, but at the same time it is starting to make you aroused.

"Good girl," says Draco menacingly. "Now spread your arms wide and put your hands at the corners of the desk."

You follow his instructions and bend forward all the way so that you can reach the corners of the desk. Then you can hear from behind Draco swishing his wand and muttering a charm. You are not sure what spell he has cast when suddenly you notice ropes appear from under the desk. They writhe around as if they are alive, before they reach up higher and start to wrap themselves around your wrists. You gasp, and before you can move you feel two more ropes wrapping themselves around your ankles. The ropes pull tight and you find yourself unable to move.

"Oh dear," says Draco smirking. "That's quite a compromising position you have gotten yourself into."

"It was you," you say.

"Yes, but you wanted it too," says Draco as he puts his hand between your legs and feels upwards.

"Hmmm, not quite wet enough yet," Draco says, then suddenly he spits on your bum. "That should help."

You hear Draco undoing his belt and dropping his trousers. Then you feel the tip of his hard penis rubbing its way between your legs.

"If you're lucky, this won't hurt as much as last time," Draco says with a cruel laugh.

"Draco, please. I..." you start to say.

"I told you before, don't call me that!" says Draco angrily. Then without warning he spanks you hard on your bare bum.

You wince in pain and pull against the ropes, trying to escape from him. But it is no good, you are held tight. Before you can move again, Draco grabs hold of your hips and thrusts forward. His penis enters you forcefully all the way inside. You gasp with the pain. It's not as bad as your first time, but it still hurts a lot when he rams it in so roughly.

Draco tightens his grip on your hips and starts thrusting into you repeatedly.

"Ahhh, that's good," he says.

Suddenly you hear the door opening. Draco stops thrusting into you for a moment, holding his penis still buried deep inside you, and turns to look at the door.

"Go away!" Draco shouts, and you hear the door close again.

"Fucking mudbloods," Draco spits, then goes back to moving his penis inside you.

Your face turns red with shame at the idea of someone seeing you having sex like this. But Draco seems to like the idea of being caught and it causes him to moan louder and thrust into you harder.

"Ahhh, yes, nearly there," groans Draco.

"Ungghh," moans Draco as he slams into you a final time and fills you with his cum.

Draco holds still for a moment and pants. Then, when he has got his breath back, he pulls out of you and starts putting his trousers back on. You go to get dressed too, but you find your arms are still tied down to the desk.

"Did you need me to untie those ropes?" Draco asks. "Sorry, mudblood, I can't remember the right charm for that."

Draco laughs loudly then walks out of the room. You wait until he has gone, then try to get your arms free. But it is no good, you are held tight.

After five minutes you are still not able to get yourself free. You can feel Draco's cum leaking out of you and trickling down your inner thighs. You want to call out for help, but you are too embarrassed by the idea of anyone finding you like this.

You hear the door open again and someone enters the room.

"Are you okay there," a voice says. It sounds like Luna Lovegood, but you are not able to turn far enough to see their face.

"No, I'm stuck," you say. "Someone was, umm, playing a prank on me."

"Oh okay, I'll get that for you," she says. "Diffindo."

You feel the ropes cut away from you and you are finally able to stand up. You quickly pull up your panties and jeans, then you turn around and find Luna standing there with an odd smile on her face.

"They play a lot of pranks on me too," says Luna. "Though I've never had this one yet."

"Yeah, it, umm, wasn't so good," you say.

"Oh well, this room doesn't look suitable, so I'm going to keep looking. Good bye," says Luna, and she leaves the room.

You quickly smarten up your appearance as best you can, then you head out the room to continue the search too.
