Title: Every Little Thing He Does Is Magic

Author: RedTundra (me)

Rating: T

pairings will be: Rose/John Smith (the Doctor), Donna/Snape, Martha/Seamus, Draco/Harry, Ron/Hermione.

A/N: This is an AU crossover of Doctor Who and Harry Potter. Rose, Donna and Martha are students at Hogwarts (they are 17) and the Doctor is a professor. But I will call him John Smith in this story, because he is not a Time Lord, he is just a Wizard.

This story is going to be mostly a romance about the Doctor and Rose, and Donna and Snape, but the story also has some SLASH in it! Harry/Draco. So if you don't like, don't read! But you shouldn't be homophobic, everyone should be able to love whoever they want.

If you like it, please, please, PLEASE review! Even if you don't like it, tell me why so I can fix it! So if you read it, PLEASE leave a review! I'll be more motivated to do the next part if I get a lot of reviews *wink wink*

Chapter 1

It was a crisp autumn day and Rose was really looking forward to going back to school. She sat in the compartment on the Hogwarts express, watching the English countryside roll by under the clear blue sky and smiled to herself.

"What you so happy about?" Martha said from beside her.

"I bet she wants to see that Professor Smith again, she fancies him," said Donna from the other side of the compartment.

"I do not!" Rose said back, but she was blushing a bit and Martha caught it.

"A-ha!" Martha said, grinning and pointing at Rose's red cheeks. "You do, you fancy him!"

"Shut it!" Rose said, pushing Martha's shoulder playfully with a smile.

"Can't say I blame her though, really," Donna said. "He is pretty cute. Did you see the bum on him?"

"Of course!" Rose giggled. Martha joined in and soon they were all giggling.

Just then the compartment door slid open and Harry Potter and Draco Malfoy came in.

"What's so funny, girls?" Harry asked.

"Oh, nothing," Rose replied, blushing a bit.

"She fancies Professor Smith," Martha told him. Rose hit her in the arm and said, "Hey!"

"Ohhh, Professor Smith," Harry said, grinning. "Well, he is quite nice."

"I said he has a nice bum," said Donna.

Rose and Martha giggled harder and Harry said, "Oh, he does."

Draco hit him in the arm and said, "Hey!"

Harry looked at him, taking his hand. "Don't worry Draco, yours is still the nicest bum at Hogwarts."

"Bloody right," Draco grinned.

"Well at least I don't fancy that awful Potions Master!" Rose said, looking at Donna.

"What? I do not!" Donna said back.

"You do, I've seen the way you look at him when you think no one is looking," Martha jumped in. "And you doodle his name with little hearts around it on your notes."

"Do not!" Donna said, blushing like mad. Even her ears were going as red as her hair.

"I think your blush speaks for its self," Martha said cheekily.

The train ride passed pretty quickly, and everyone had a good time chatting and teasing each other. The train finally pulled up to the station and then everyone got into the carriages that took them up to Hogwarts.

Everyone went to their dormitories to get settled and put away their luggage. Harry, Rose, Donna and Martha all went to Gryffindor, which was the house they were in, and Draco went to his dormitory because he was in Slytherin. Rose, Donna and Martha put their trunks up in their room, which they all shared with Hermione. They shared with her last year too, and none of them really liked her much because she was so bossy, but they still tried to be nice to her. She wasn't here yet though, so they had the room to themselves for now.

After they put their trunks away and got changed into their robes from their Muggle clothes, the girls went back downstairs to the common room and sat down by the fire.

Harry came down soon afterwards and came up to them with a smirky grin. "Who wants some beer?"

The girls looked at each other and then looked back at Harry. "Why, do you have some?" asked Martha.

"Yeah, I have a case up in my room," said Harry, jerking his thumb back towards the door he came from.

Martha looked around at the other girl's faces and then she grinned. "Okay, I'll have some."

Rose smiled a little bit nervously, like she was scared of getting caught. But she did want some. And she was 17 now, after all. "Okay, me too."

"And me," said Donna, tossing her red hair over her shoulders. "I don't want to be left out if you all are going to have some."

"Awesome." He left to go get it.

Rose pulled her knees up to her chin, wrapping her arms around her legs. All the girls exchanged glances and grinned.

"We are like, so bad! What if we get kicked out?" said Donna, getting a bit worried now.

"Don't worry, we are some of the best students in our year!" said Martha reassuringly. "They wouldn't kick us out."

"Plus," added Rose, "how are they going to find out?"

"What if that nosy Hermione tells on us or something?" Donna said, still looking worried. "I don't think she likes us, she's always looking for something to get us in trouble."

"Don't worry, you worry too much, Donna," Martha grinned, hitting her lightly in the arm.

Harry came back with the beers and he handed one to everyone. "Cheers," he said, popping the top off and raising his bottle.

"Cheers," replied the girls, opening their own bottles.

Rose took a sip of hers. "Mmm, not bad."

Donna took a sip of hers as well. "Bleck, it's strong."

Suddenly, Hermione came into the common room through the Fat Lady portrait. Everyone tried to hide their bottles, but they didn't do it quick enough, and she saw them. She stuck her nose up in the air and turned right back around and marched back out of the room.

"Bollocks!" said Donna. "She's going to tell on us! I knew this would happen!"

It was hardly even a minute before the portrait swung open and somebody came through. Everyone gulped as they waited with anticipation to see who it was.

It was Snape. Everyone's hearts fell, because they knew they were going to be in a lot of trouble.

"Drinking in the common room, is it?" Snape said, and his voice was low and sinister. "And on the first day! You're going to have to be punished for this, I'm afraid. I'm sure we can arrange something."

A/N: Sorry it's such a short chapter, but I'm really busy at school right now. Hopefully I will get the next part up quickly! Thanks for reading, and dont' forget to review!
