Desperate Measures

After donning the robe that Ginny had lent her, Mary Sue looked down at herself and said, “These really aren’t very flattering, are they? They do nothing for my figure.”

“You only have to wear it for classes mainly,” Ron said. “And some of the more formal meals like tonight.”

When they got off the train, Mary Sue looked around the Hogsmeade station. How quaint everything seemed. When her eyes fell upon Hagrid yelling, “First years, first years over here,” she yelped and grabbed onto Harry’s arm.

“Oh my,” Mary Sue said. “Look at that enormous man, Harry. I’ve never seen …”

“That’s Hagrid,” Harry said, enjoying the snug feel of her hands around his arm. “He’s a professor at Hogwarts and he’s a really great fellow.”

“He’s so… so… big and … hairy,” she said with wide eyes.

“He’s a half giant,” Ron explained.

“A what?” Mary Sue looked at him. “Did you say giant?”

“Yeah,” Ron smiled at her. She seemed so amazed at his explanation.

Further away, Draco stood with his group of Slytherin friends looking around the station. When he spotted Mary Sue standing with Ron and Harry, he pulled on Blaise’s arm to get his friend’s attention. “Blaise, there, that’s the one I told you about.”

Blaise looked where Draco indicated and he exclaimed, “Suck Merlin’s cock! That one’s definitely going to the top of the ‘most shagable’ list.” Blaise pulled out a small journal from one of the pockets of his robe and a quick quill. He opened the book to a page which contained a numbered list of girls at Hogwarts. Tapping the list with his wand, all the names moved down one spot, leaving the top spot open. “What’s her name?” he asked Draco.

“Lady Meredith Suzanne Perfect,” Draco said, leaning over Blaise’s arm to watch him add her name to the list.

When Harry, Ron and Mary Sue followed the crowd out of the station and to the waiting carriages she ceased staring at Hagrid and looked at their expected mode of transportation. “We’re going by carriage?” she said, amazed. “This feels like an amusement park! Where’s the horses?”

“They’re invisible,” Harry said. “And they are not really horses, they are threstrals.”

Mary Sue looked at his face, expecting him to admit he was just kidding. When he didn’t, she laughed and said, “Oh Harry. You’re a funny one.”

Ron opened a carriage door for her and watched her climb in. While Mary Sue was inside looking for some sort of driving mechanism, Harry grabbed Ron’s arm and pulled him away from the carriage a bit.

“Ron, I think Mary Sue is a muggle,” Harry whispered.

“What?” Ron laughed. “She wouldn’t be here at Hogwarts if she were a muggle, Harry.”

“Think about it, Ron,” Harry said. “Every time we mention something about the magical world she laughs and thinks it’s a joke.”

“But…,” Ron said in confusion.

Harry pulled Ron towards the carriage and said, “Let’s ask her some questions.”

They got into the carriage. Ron sat next to Mary Sue and Harry sat across from her. She smiled at them both and said, “Are we supposed to drive this thing some how?”

Harry gave Ron an I-told-you-so look and then said, “Mary Sue, what school are we going to?”

She looked at Harry strangely and laughed, “Don’t you know? Travers Academy of course.”

Ron and Harry looked at each other again and then Harry said, “Do you still have your train ticket stub?”

“Yes, I believe so,” she said, reaching under her robes and into a pocket on her skirt. “What’s this about, Harry?” She handed Harry the ticket stub.

“Platform 10,” he said aloud, handing the ticket to Ron.

Ron groaned and said, “You fell through the barrier.”

Now she was thoroughly confused and she said, “What are you both going on about?”

“Mary Sue,” Harry began. “We’re not going to Travers Academy. We’re going to Hogwarts School of Witchcraft and Wizardry. You got on the wrong train.”

“This is not funny anymore,” Mary Sue said. “Please stop joking with me. Are you two into fantasy role playing or something? Witches, wizards, giants, invisible horse thingies…”

Harry shook his head and said, “I know it sounds unbelievable. I was surprised the magical world existed myself until I got my letter to come here. I grew up with muggle relatives.”

“Muggles?” she asked, becoming more convinced that these two were touched in the head.

“Non-magical people,” Ron said.

“I’ve heard enough,” she said in irritation. “I thought you two were decent…”

Harry knew he would have to prove it to her so he pulled out his wand and pointed it at Ron. Ron began floating up as Mary Sue watched in amazement.

“How… how…?” she stuttered.

“Magic,” Harry said, letting Ron fall back down in his seat with a thump. Ron glared at him.

Her hands flew to her mouth and she looked at them in horror, “You’re telling me it’s real? There is really a school for witches and wizards?”

“Yes,” Harry said, “and it’s right up that hill.” He pointed at the castle now visible from their window.

“A castle? How come I’ve never heard of this place before?” she asked.

“The magical world is kept separate from the muggle world. A lot of effort is made to hide our existence,” Ron explained.

“What I’m I going to do?” Mary Sue panicked. She looked out the window at the beautiful castle set above a lake. It really was lovely. Lovelier than Travers Academy would be, she wagered. She turned helpless eyes towards Harry and Ron saying, “Please, you’ve got to help me. I feel so lost.”

The boys couldn’t help wanting to comfort her. Ron looked at Harry and said, “Harry, isn’t there any way Mary Sue could stay at Hogwarts?” He really didn’t want to see her go, especially after that sexy train ride and the promises she had made for more.

Harry didn’t see how that could happen. He was about to say so when Mary Sue said, “Oh, yes, please. I would like to learn magic. It would be much more interesting than the boring subjects I usually have to take.”

“Well…,” Harry began. “You’d have to be able to use a wand, Mary Sue. I’m not sure the professors would look past that.”

“We could help her out with that, Harry,” Ron said. “When she’s asked to do something, we could secretly do it for her.”

“Would you?” Mary Sue asked, smiling at Ron. She scooted closer to him and pressed her breasts against his arm while she took his hand in hers. Ron’s heart sped up and he nodded at her.

Ron looked at Harry, pleading with his eyes. “Come on, Harry. We can do it. Do you really want to see her leave?”

Mary Sue looked at Harry. Then she switched seats so that she was next to Harry and sitting with her breasts pressed against his arm as she pleaded, “Please help me, Harry. I very much wanted to get to know you and Ron better.” Her hand went on his leg and she added, “Much better.”

Harry swallowed. He very much wanted to get to know her better too.

“All right,” Harry said. “We only have a few minutes to plan this before we get there. This is what you should say…”

They put their heads together, scheming with the time they had left.

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

As everyone filed through the front door of the castle and into the great hall, Harry and Ron led Mary Sue to Professor McGonagall, who was standing off to the side and watching as the students made their way to their house tables. Professor McGonagall looked at Mary Sue in curiosity. She wasn’t aware that there had been any new transfer students this year.

“Professor,” said Harry. “This is Meredith Suzanne Perfect; she’s a transfer student from Beauxbatons.”

“Hello,” Meredith smiled brightly.

Professor McGonagall’s eyebrows shot up in surprise. “Well, this is unusual. I’ve had no notice of your transfer, Ms. Perfect.”

“No, you wouldn’t have, Professor,” Mary Sue replied. “My parents pulled me out of Beauxbatons only yesterday. They had a disagreement with the head mistress there, you see. It was a last minute decision to send me here.”

“Oh?” Professor McGonagall looked at her thoughtfully. “I see. Well, I’m sure your file will be arriving shortly then.” Harry and Ron looked at each other, knowing that they’d have to do something about a ‘file’ for Mary Sue.

“Yes, Professor,” Mary Sue smiled, trying not to look worried.

“Come along with me, Ms. Perfect,” McGonagall said. “You’ll have to be sorted with the first years.” She followed Professor McGonagall out of the great hall, turning to glance worriedly at Ron and Harry before she was out of sight.

“Harry, what are we going to do about her paperwork?” Ron whispered as they made their way to the Gryffindor table.

“I don’t know yet,” Harry said. “I’ll think about it during the feast. Let’s hope she gets into Gryffindor.”

Hermione looked away from them as they sat down. She was still miffed at them and they knew she would definitely not help Mary Sue if they asked her.

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Mary Sue was all eyes as she looked around in wonder. She stood with the group of first years at the side of the great hall and waited to be sorted. The enchanted ceiling fascinated her and all the professors at the head table were dressed in strange cloaks. She didn’t notice everyone, especially the boys who were craning their necks to get a good look at her. All the first years were to be called up first and she looked on in amazement as the hat placed on their heads began to speak and shout out which house they belonged in. Her eyes followed a small boy as the hat called out, “Slytherin,” and he made his way to a table. It was there she noticed Draco Malfoy, the blonde boy from the train, staring at her. He smiled and gave her a wink when she caught his eye. She gave him a smile back and then looked away.

When the hat had finished with all the first years, McGonagall said, “Ms. Meredith Suzanne Perfect.” Mary Sue walked up to the stool and sat down nervously. All eyes were on her and the room was very quiet. She didn’t know that many of the boys in all four houses were crossing their fingers and hoping that she’d get put in their house.

The hat was placed on her head and it was silent for awhile. Then she heard a voice in her mind. “No magical ability? Hmmm, how can this be? This has never happened before.”

Mary Sue’s heart filled with dread. She knew that hat would shout out this fact in front of the whole school. She didn’t know that the hat had been charmed to not give out degrees of magical ability so that no students felt superior or inferior to any one else.

Time stretched on as the hat screwed up its face in indecision. Professor McGonagall took a few steps forward and peered closely at the hat. Finally it shouted out, “No house! No house! Meredith Suzanne Perfect does not belong at Hogwarts School of Witchcraft and Wizardry!”

Immediately the noise level rose as the students expressed their disbelief. The professors at the head table all looked at each other in surprise. This had never happened before!

Meredith felt stunned with embarrassment and shame. The faces of countless headmasters and headmistresses filled her mind, telling her how she didn’t belong at their schools and that she would have to leave. She wasn’t wanted. She wasn’t wanted any where. Tears began to fall down her face.

McGonagall looked at the hat and said, “Please try again. She must have a house.”

“No house! No house!” the hat started chanting, louder and louder. McGonagall took the hat off her head and turned to Professor Flitwick.

“Professor,” she said. “Could you please examine the hat? The charm must be malfunctioning.”

Flitwick slipped off his chair and took the hat from her. He walked out of the hall with the hat still shouting, “No house. No house.”

“Now, now, dear,” Professor McGonagall said to Mary Sue. She handed the distraught girl a handkerchief and said, “Dry your eyes; I’m sure the headmaster will find a solution.”

Dumbledore had already risen from his seat and raised his hands up to silence all the chatter. Before he could speak, however, Draco Malfoy had stood up and said loudly, “Slytherin house would be happy to have Ms. Perfect.”

Ron stood up, glaring at Draco, and said, “Gryffindor house would be better suited for Ms. Perfect.”

“Sit down, please,” Dumbledore said. “It is kind of you boys to offer, but I believe that this will have to be done another way.” Mary Sue stopped crying and turned slightly to look at Dumbledore. He smiled kindly at her and said, “It is unfortunate for you, Ms. Perfect, that after hundreds of years of faithful service, our sorting hat has chosen this particular moment to malfunction. So, I believe we will have to make an exception in your case and allow you to choose which house you would like to belong to.”

Mary Sue turned her face and glanced around the room. She knew that she needed Ron and Harry to help her if she wished to stay here. She looked at Dumbledore again and said, “I would like to be in Gryffindor, sir.”

“Very well, Gryffindor it is,” Dumbledore announced loudly. The Gryffindor boys all cheered loudly while Hermione and Ginny rolled their eyes and shook their heads.

Draco frowned and turned to whisper to Blaise.

Mary Sue went to sit with Ron and Harry who had made a space for her between them. “We did it!” she whispered excitedly in Harry’s ear.

“There’s still more to do,” Harry whispered back. “But don’t worry. I think I have a plan.”

She put her hand on Harry’s leg under the table, caressing him with her fingertips as she whispered, “I’m so grateful to you, Harry. I promise I’ll show you just how much this means to me.”

Harry was glad his lower half was hidden under the table as he felt himself hardening at her words and her hot breath on his ear.

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

At the end of the feast, Professor McGonagall called for the prefects to show the first years the way. She stopped Hermione and said, “Ms. Granger, I believe there is still an empty bed in your room. I’d like Ms. Perfect to room with you and Ms. Brown and Ms. Patil.”

“Yes, Professor,” she said. Hermione turned around and grimaced. “Just great,” she muttered. “I have to room with that… that…”

Ron walked up to her and said, “What’s your problem?”

“You!” she snapped. “You’re my problem.”

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

When Hermione had finally finished with her duties she walked into her dorm room to find Mary Sue laughing with her roommates and spreading all sorts of decorations around her bed space. “Oh, hi Hermione,” Mary Sue smiled. “Isn’t it wonderful? We are going to be roommates. This will be so much fun!”

Hermione put on a fake smile and gave a forced laugh. “Yes, loads of fun!” She turned towards her bed and rolled her eyes. She looked at Lavender and Parvati, who didn’t seem put out by Mary Sue at all. In fact, they looked like they were enjoying the girl’s annoying chatter.

As they were getting ready for bed, Professor McGonagall popped in and said, “Ms. Perfect, after breakfast tomorrow I’d like to meet with you to discuss which classes will best suit your abilities. Bring your wand.”

Mary Sue’s face fell in worry.

“Is there a problem, Ms. Perfect?” McGonagall asked.

“Well, yes, Professor,” Mary Sue said. She remembered what Harry had told her to say. “You see, with all the hurry in changing schools, my other trunk with my uniform and wand and supplies was left behind somewhere. I even had to borrow this robe from Ginny Weasley.”

McGonagall sighed and said, “No matter. There’s a supply room, a sort of lost and found; items that get left behind or misplaced from students past and present end up there. I’ll take you there tomorrow. I’m sure we can piece together a uniform for you. There may be a cauldron and perhaps some of the books you’ll need as well. As for the wand, I have some wands which I call, ‘neutral control wands.’ You may borrow one of those. It won’t be as powerful as your own, but it will do until you can get your own back.”

Mary Sue’s face brightened and she said, “Oh thank you, Professor!”

“You’re welcome,” she replied. “Goodnight girls.”

Mary Sue sighed in relief, one more obstacle out of the way. She slipped on her baby doll teddy with matching panties. The other girls had much more conservative nightwear and they looked at her in amusement. “Cute pajamas,” Lavender commented.

“Thanks,” Mary Sue said. She swooped up her big shoulder bag full of her creams and beauty tools. “I’m off to the bathroom for my nightly beauty routine,” she announced. She waved goodbye and left the room. Hermione turned her head to Lavender and Parvati. “What did I tell you?” she said. “We just got stuck with Malibu Barbie.”

“Who?” Parvati asked, not familiar with muggle toys.

“Never mind,” Hermione grumped and slipped into bed.

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Harry and Ron were in their room studying the Marauder’s map for McGonagall’s movements. “I don’t think she’ll go to bed anytime soon,” Ron said. “She’s got to make sure the first years are settled.”

“That’s good, though,” Harry said. “I’ll just go down there now and get it. If you see her starting to leave the dorms then go and stall her.”

“All right,” Ron said. “Good luck.”

Harry threw on his invisibility cloak and left Gryffindor, making his way to McGonagall’s office where she kept all the academic files of the Gryffindor students. He unlocked the door and went to the file cupboard behind her desk. Pulling out his own file, Harry took his wand and said, “Duplicato.” A duplicate file folder with all the papers inside it appeared next to the original. Putting his original one back, he snuck to his dorm room where Ron was waiting.

“Got it,” he said, throwing off his cloak. “Now we just have to change everything to Mary Sue’s name and adjust the personal information.”

“If it’s from Beauxbatons, wouldn’t it all be in French?” Ron asked.

“Fuck! I forgot about that. Do you know any French?” Harry asked.

“No, but Neville does,” Ron said.

Ron and Harry had used a silencing charm while they sat on Harry’s bed with the draperies shut and a wand lit. Harry looked at Ron and said, “Think we should get Neville involved?”

“What choice do we have?” Ron replied.

Harry removed the silencing charm and walked over to Neville’s bed, shaking him awake. “Neville,” Harry said.

Just then the dorm room door cracked open and the hallway light flooded in as they heard a girl’s voice saying, “Harry? Ron?”

“Mary Sue?” said Ron from Harry’s bed.

She stepped into the room and shut the door saying, “Thank goodness I found you! A boy named Colin said this was your room.”

They didn’t answer her right away as they were too busy looking at her long shapely legs. Her nightie was almost high enough to expose her knickers and it was obvious she wore no bra by the way her nipples were poking against the fabric. Soon Ron’s wand light was joined by Seamus’s, Neville’s and Dean’s as the sound of her voice had roust them from sleep.

They were all gaping at her and Seamus said, “Merlin! I think I died in my sleep. Is this heaven?”

She smiled coyly at him as Harry approached her. “Mary Sue, what are you doing here? You could have been caught by McGonagall.” Gods she was hot! Harry felt his stomach do flip flops the closer he got to her.

She grabbed his arm and said, “Oh Harry, I just had to talk to you. McGonagall’s going to test me tomorrow, Harry! What should I do?”

Harry looked at his other roommates who were still mesmerized by Mary Sue’s appearance. “Well,” he said nervously. “Come over here and we’ll think of something.”

He wanted to put another silencing charm up so that the others wouldn’t know what they were doing, but Dean said, “What’s going on Harry?”

Seamus got out of bed and walked over to Ron who had papers spread out all over Harry’s bed. “You can’t have any homework yet.”

“Just mind your business, Seamus,” Ron said. “This doesn’t concern you.”

“If you’re going to be doing…,” Seamus looked at Mary Sue, “illegal things in our room, I think it does concern me.”

“Who said…,” Ron began until Harry raised his hand to stop him.

“Ron,” Harry said, “we’re going to need help if we are going to pull this off. We can trust them.” Dean and Neville now walked up and waited for an explanation. They also wanted to get a closer look at the front of Mary Sue’s nightie. She wore an expression of helplessness that none of them failed to miss as she clung to Harry’s arm. She knew exactly how to affect their emotions; she was a master at twisting boys around her little finger.

Harry looked around at them all and said, “We need you all to swear that what we say will not leave this room. Do you swear?”

They all swore and then Harry said, “Mary Sue is a muggle.” After their initial surprise Harry went on to explain everything that had happened so far and what they were planning to do to keep her here. Then he said, “Will you help us?”

“Well…,” Neville said, “I don’t know, Harry. What if we get caught?”

Mary Sue knew she would have to step in to do the convincing. She put on a hurt expression that made them all want to hug and comfort her. “Please Neville,” Mary Sue begged. She took the few steps needed to stand directly in front of him. His arms were crossed in front of his chest and she placed her soft hands on them. “Please Neville, I want to stay and learn magic. I want to make new friends here, friends like you.” Leaning slightly forward, the tips of her nipples barely grazed his arm and Neville’s body jerked in reaction.

“I… I… I…,” Neville stuttered.

“Oh for fucks sake, Neville!” Seamus exclaimed. “If you don’t say yes to that, then there’s something seriously wrong with you!”

“Yes!” Neville practically barked out. She threw her arms around Neville’s neck and hugged him tight. Neville almost groaned as he felt her ample bosom pressed against him. He backed his hips away so that she wouldn’t feel how hard he was at the moment.

“Thank you,” she said, kissing his cheek. She let go of a smiling, blushing Neville and turned to Dean, looking at him in question.

“Yes, I’ll help you too, Mary Sue,” Dean said with a slightly horse voice, hoping he’d get a hug too. She didn’t disappoint him. Dean let out a small groan when she pressed herself against him and his hands wrapped around her back. She smelt so wonderful.

“Don’t I get a hug?” Seamus asked.

She let go of Dean and turned to him. “Of course,” she smiled, wrapping her arms about him.

‘Oh, yes, this is good,’ Seamus thought as he pulled her firmly against him, not afraid to let her feel his erection against her belly. His hands slid down over her ass and he pulled her pelvis forward onto his bent leg, getting a feel of her damp panties on his thigh.

She giggled and pushed away from him saying, “You are so naughty.” But the look she gave him expressed her pleasure at what he did.

“Yes, I’m very naughty,” he said, wagging his eyebrows at her.

“All right,” Harry said, “we need to get this done. McGonagall is expecting her file tomorrow. Neville, we need you to do some translations in French and then you need to get up very early tomorrow and owl this to McGonagall as if it were coming from France.”

Mary Sue put her hands on Harry’s chest and looked up into his eyes, “What about the test tomorrow?”

“I’ll be with you. I’ll slip on my invisibility cloak and follow you. Just point the wand and say the words that I whisper in your ear. I’ll be using my wand under the cloak to do whatever magic she asks for,” Harry said. He no longer cared that his cock was tenting out as it seems all five of them were suffering from the same problem.

“Oh, Harry,” she said, hugging him. “You’re so smart. Thank you so much.”

She turned to all of them and said, “I’m going to owe all of you so much for helping me. Perhaps I can come back again and visit another time?”

“Sweetheart, you can come back and visit every night,” Seamus said.

She smiled teasingly as she made her way to the door. “Maybe I will,” she said before she left.

The five boys looked at each other in silent disbelief for a moment. “All right,” Harry said. “Everyone take a fifteen minute break to wank off and then meet back here.” They all hurried to their own beds and shut their draperies.

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

A/N I wasn’t sure that they had Malibu Barbie’s in Britain. LOL Hope you enjoyed this. I promise more sex in the next chapter. I needed to set up exactly how she will fool everyone so she could stay at Hogwarts. As you can see, the boys will do almost anything to make sure she does stay.

Please let me know your thoughts on this chapter! Thanks!
