The Princess in Pants

Chapter 1

Be my friend, hold me

Wrap me up, unfold me

I am small, and needy

Warm me up, and breathe me

Once upon a time, in a far far away kingdom, a beautiful princess was captured by an evil dragon who kept her prisoner in the highest tower of his castle. It was said that the princess was so pretty, the hideous creature considered her as a treasure to hide and never share with anyone. The poor princess lost hope along the years to gain her freedom back. But one day, a courageous prince decided to fight for the beauty and-

"Oh man, this is utter bullshit. I can't believe you actually bought this."

Lucy pursed her lips as she slammed the book on her lap. She glared at the girl who was obnoxiously yawning in front of her, showing she was already bored with the story.

"I don't know what bedtime stories you heard when you were little, but in Far Far Away, that's what our mothers tell us, and it actually comes true!"

"Don't tell me you've been waiting for Prince Charming your whole life…" the girl looked at her worriedly.

"Don't be stupid, Prince Charming is Princess Fiona's fiancé. It's been a while since we've seen him around… I wonder where he went."

"Probably in hell where he belongs."

"How could you say that?!" Lucy hissed. "I can't believe you're a princess yourself. You hardly look like one, and I've never heard of you before." she inspected the very odd looking princess who was swinging on her chair.

She had long messy pink hair, jet black eyes with a mischievous glint in them, but that wasn't what caught Lucy's attention at first sight…she was wearing men's clothes. Pants. No crown, no dresses, no jewels.

"I am one though." the pinky stood upright, then bowed, tugging her invisible dress. "I am Princess Natsu Dragneel, from the Next Door Kingdom."

"There's no Next Door Kingdom." Lucy rolled her eyes as Natsu snickered. "I still don't understand why I'm stuck with you here."

"For the tenth time since you invaded my room, because your dear father King Heartfilia asked my dad a favor, and he couldn't refuse." Natsu grumbled.

"And I still don't understand. I was supposed to be kidnapped by a dragon and held in his tower so that a prince would come rescue me, just like Princess Juvia."

"So?" Natsu collapsed on her bed. At least her room was spacious – very spacious – and comfortable. Enough for a princess like Lucy. The room was settled on top of a tower that was higher than Rapunzel's. When she had seen it for the first time this morning, Lucy had been quite glad. Obviously her prince would be very handsome and brave to climb this tower up AND fight the dragon at the same time.

"So I'm in the tower, but where is the dragon?!" Lucy exclaimed, tired of having to explain everything to this very uncanny princess she had never heard of before.

"Who knows." Natsu laughed.

Meeting her had been quite a shock. Lucy thought at first that Natsu was a peasant ready to murder her and steal her belongings. After she calmed down and understood she lived there, she thought Natsu was here to be her maid. It had taken the other princess one hour to make Lucy understand she wouldn't move a finger for her, and that she could wash her dishes herself.

"It doesn't make any sense." Lucy sighed as she paced through the room, observing Natsu's things for the twentieth time this day. She had amazing paintings everywhere on her walls. A beautiful poppies field here, the raging sea there, people dancing around a fire… The artist was talented, Lucy thought. She could almost feel the fire heating her skin.

"You like my stuff?" Natsu asked, eyeing her from her bed.

"…you painted these?!" Lucy widened her eyes.

"Why do you seem so surprised? Just because I look like a peasant doesn't mean I can't do noble things." Natsu stuck her tongue out.

"No kidding…" Lucy focused on the paintings again. "It's absolutely beautiful."

"Thank you, milady."

Lucy rolled her eyes again at the honorific. "Why do you wear pants?"

"It's the fifteenth time you ask."

"That's not an answer."

"That's the only one you'll get."

"You're annoying."

"And you talk a lot."

"Are you sure you're not a boy? You act exactly like my cousin Max when he wants to annoy me."

Natsu burst out in laughter. She got up, then to Lucy's surprise, she opened her torn button shirt, revealing her half naked body. Her breast was only covered by a strange clothes, looking like a corset, but without the part covering the belly. There were also straps, going around each shoulder. The fine lace of the clothes was the only thing that could mark the girl's noble status.

"I'm definitely sure I'm not a boy."

"What are you doing?! Cover that right now!" Lucy shrieked as she rushed towards her companion and closed the shirt. "You don't even wear a corset!"

"Why would I? It's so uncomfortable. Just like you right now." she snickered while she pinched Lucy's red cheeks.

"Of course I'm uncomfortable, it's unlady-like to show your breast." she smashed her hand away. "What is that thing you're wearing anyway?"

"It's a bra. You don't have that in Far far Away?"

"Certainly not! A proper lady wears a corset."

Natsu snorted. "You seriously need to relax."

Lucy ignored her. She contemplated her work, satisfied to see she managed to unfold Natsu's rebellious shirt and make it look a little bit elegant. Somehow.

"I'm starting to be hungry, I'm gonna go get something downstairs." Natsu walked to the exit. "You wanna eat too?"

"How do you get food?! There's nothing but a forest around here!" Lucy startled instead of answering.

"I can create food by magic, I just need to snap my fingers."

"I'm not that gullible." Lucy pouted. She jumped on the huge bed and took off her shoes. She bet Natsu wouldn't mind.

"Good for you." Natsu grinned as she opened the door. "By the way, this is my bed. Until I consider you're not a psycho, you sleep on the couch."

In fairy tales, between the kidnapping of the princess and the rescuing, there was nothing said about her living conditions. Lucy realized that the authors made a terrible mistake there. If she had known how painful it was to be a captive princess, she wouldn't have agreed that fast.

She was right now extremely miserable in her bed –sorry, her couch- freezing under one thin blanket, because Natsu had a natural high body heat and didn't feel the cold. She also had to sleep in a room illuminated by the vivid moon light, making it even more impossible to fall asleep.

She glanced at Natsu's bed, on the other side of the half-circle shaped hole that served as a window. She was peacefully sleeping, with her blue cat named Happy purring next to her. What an odd princess indeed. She did everything by herself, from cooking to washing her clothes, and didn't seem bothered by it one bit. She was also very mysterious.

Lucy learned that she apparently didn't live in this place all the time. Her father, King Igneel Dragneel, had made this tower for her to hide in whenever she wanted some alone time. It sounded pretty weird for the Heartfilia heiress, who always hated to be alone. Besides, who would want to hide in a high tower away from civilization like this?! This fortress looked more like a dragon's den.

She twirled a blond strand of hair around her finger and sighed. She already missed her family, even her father, who had barely paid attention to her since her birth. She hoped her prince would come get her soon, so that she could see her mother and cousins again.

Unfortunately, sometimes princes took their sweet time to start their quest. Princess Juvia had to wait many years before her Prince Gray decided to defeat the iron dragon that guarded her.

Lucy tried to imagine herself spending years in that boring tower, alone with Natsu… Anything but that. She didn't think she could ever get along with her. They shared nothing in common… The mean pinky didn't seem to want to befriend her anyway. She was always rude, and never wanted to help her.

For example, she laughed and ignored Lucy when she politely asked her to help her unlace her dress and corset. The blonde noble had to humiliate herself, squirming in her dress for half an hour before she managed to take it off. Of course Natsu didn't miss a piece of the show. She promised the fuming princess she would paint the scene someday.

Lucy sighed again. This was going to be a painful waiting.

The princess jolted when she heard Natsu loudly huff in the dark. The uncanny noble got up and headed towards Lucy. When she passed the moonlight, Lucy saw her eyes blazing like two black stones on fire… They were so mesmerizing it scared her for a second. They didn't look…human.

"I can't stand hearing you sigh all the time." Natsu only said, and put her heavy blanket on Lucy's back. Then she went back to her own bed, leaving the blonde puzzled in her couch.

Lucy smiled and snuggled under the warm cover. Maybe she had misjudged Natsu. Who knew.

She hadn't misjudged Natsu. It had been two weeks now, and the two of them were just bickering and arguing all the time. Natsu didn't want to teach her how to cook, wash her clothes or prepare a bath, or anything practical, and didn't want to do it for her either. How was she supposed to keep her dresses clean and proper? Or eat something edible?

"Learn by yourself, that's the best way to remember." was what the obnoxious girl always replied. " If I start to teach you, I'm gonna end up doing it for you all the time, I can see it coming."

"You're wrong! I really want to learn!"

"Oh really? Prove it!"

"That's what I've been trying for two weeks!"

"C'mon, you're not really trying, you've been whining in front of the pan for half an hour."

"I don't know how your archaic hotplate works!" Lucy yelled. "And last time I tried, I burnt my favorite dress!" she shoved in her face the ruined tissue of her sleeve, tears threatening to fall on her cheeks. Natsu raised her eyebrows at her, crossing her arms under her chest.

"Don't tell me you're gonna cry for a piece of clothes."

Lucy looked up at her, sending her most murderous daggers through her glare. She understood quickly that the 'damsel in distress' mode didn't work at all on Natsu. When she saw a spider the day before, she had to crush it herself, because Natsu was busy painting.

Oh let's talk about painting. Remember when Lucy was admirative of Natsu's skills? That was long gone when she realized that paint STUNK, and that Natsu used half of the room as her workplace. Of course Lucy wasn't allowed to see. She just had to endure the smell, the spots on her dress that Natsu made 'by accident', and the humiliation of not being welcomed in the artist's world.

"I'm not going to cry, Dirty Princess."

"You know you shoud stop calling me that." Natsu smirked.

"Why? It fits you perfectly." Lucy lifted her chin like every time she wanted to make Natsu feel inferior. The Dragneel princess cackled and suddenly closed space between them, placing her face only inches away from Lucy's.

"You don't see the meaning behind, do you?" she smirked again. Lucy blushed at the closeness, but backed away almost immediately.

"You know nothing about manners and personal space." she replied.

"And you know nothing about life." Natsu stated with a consternated tone. "My, my… I wish good luck to your future prince."

"At least I can get one." Lucy spat, infuriated by her roommate's behavior. "I'm not going to stay alone in my tower my whole life."

Natsu raised a brow and gave her a hard stare before shrugging.

"I bet your daddy's gonna be so proud of you when you finally get your prince."

Lucy stiffened. Touchée. Right on the sensitive string. Natsu had realized during the two weeks that Lucy had some father issues. But she'd never mentioned it before. Or attacked Lucy on it. She wondered if she had touched Natsu's sensitive string as well…

They stared at each other for a few more seconds, then Natsu walked out of the room, taking Happy with her. She needed fresh air. Lucy felt a bit guilty as she watched from the window the mysterious girl pick up the fish lines she had settled in a lake nearby this morning.

She loved to fish. She often talked to her cat there, while she thought she was alone, and Lucy found that very cute. If there weren't these nice moments, she would just hate everything about her captive days.

Lucy frowned as she saw Natsu hug her cat and sadly talk to him. She regretted this argument. She wished she could be friend with the weird princess. Not just because it was practical to get along with one's roommate. But also because she felt there was a more cheerful Natsu underneath that harsh and sarcastic person.

Maybe Lucy hadn't tried enough indeed… She sighed.

Natsu snapped her head at her, an intense glare on her face. Lucy backed away from the window, her heart beating fast. Busted. But how did she know?! She couldn't have heard her sigh!

"What are you doing, weirdo?"

Lucy didn't look at her mocking roommate. She had to focus if she didn't want to fall from the unbalanced chair she perched on.

"I'm trying to reach the cake bowl. I want to cook." she said as she stretched her arm further. She could almost touch the bowl… Why was it on top of the highest cupboard?!

"No way, you want to cook? That'd be a first." Natsu crossed her arms under her chest, enjoying the view. She was mocking Lucy but deep down she was pleased to see the princess finally make efforts. One week had passed since their argument, and Lucy had spent her time following and observing Natsu to learn by herself how she did 'things of life'. It was a bit irritating, but Natsu appreciated the intention.

"Shut up, or you won't have any."

"Do you need help?"

"I thought you didn't want to help me."

"Well until today you never really tried."

Lucy huffed, her ego a bit hurt. "But now that I'm trying, I'm not going to give up!"

Natsu held back a smile. What a brat.

"You know there's another cooking bowl in the drawer below the hot plates right?"

Lucy froze, red coming to her cheeks. She didn't have to look at Natsu to know the princess-in-pants was smirking.

"You're telling me only now?!"

"You didn't ask."

"You just want to see me struggle for nothing." Lucy huffed.

"I can't deny that I like it very much…"

"You filthy little- AAAAH!" Lucy had lost her balance, and was falling from her chair. Her nape roughly landed on a sharp surface, while she felt her body caught in two arms.

"I knew this would happen." Natsu giggled. Lucy looked up at her, a nasty frown on her face. Her nape was aching since it had hit Natsu's shoulder.

"It hurt, you idiot!"

"Oh stop it big baby, it was either me, either the floor. I think it would have hurt far more if I had not anticipated your clumsiness." she smirked.

She let go of Lucy, who fixed her dress as she grumbled profanities towards her roommate. Natsu found the other bowl in the drawer and put it on the table.

"Come on, I'm gonna teach you how to cook." she reached her hand out to Lucy, a genuine grin on her face. Lucy blinked twice, having a hard time to believe she could have such a nice and pretty face. She shyly smiled back, still a bit suspicious, and took her hand.

Life went on like this for a couple of months, Lucy learning how to live in a more humble way, and Natsu starting to appreciate the big baby's company.

The weirdo proved that she could learn quite fast! She even stopped complaining about every little detail that bothered her. The biggest progress that Natsu saw, was when Lucy broke her nail whilst cleaning her part of the room, and didn't even whine. Joke aside, she really tried to change Natsu's opinion about her.

Therefore the tower inhabitant started to open up progressively to the captive princess. Her suspicious stares turned into grins. Their arguments turned into talks. Lucy talked most of the times of her princess life, and Natsu commented every strange noble manner she could. As for her, she started only recently to talk about her family, describing her cheerful dad, her genius brother, and loving mother.

Lucy felt envious of her deep connection with her father. Her own dad was only interested in her marriage. However, she thought that the Dragneel royal family was very tolerant with Natsu's peasant manners… She had still trouble getting used to her bizarre attitudes, like her lack of boundaries.

Sometimes Natsu would get so physically close to Lucy it was disturbing the blonde noble. Nobody ever stood so close to her, except her mother or the maids who took care of her. Natsu wasn't a maid, nor a person of her family. It was…strange to feel her breath on her face, or feel her touch her, even if it wasn't anything shocking.

She tugged her wrist when she wanted to lead her somewhere for example. That was odd for a noble. She put her hands on her shoulders when she wanted to reassure her, like the time when she tried to make Lucy climb a tree. It had shocked her at first, but after a while, she started to actually like this proximity. Even if it still disturbed her.

Lucy realized Natsu started to like her when she allowed her in her artist world. The Heartfilia princess was so excited the day she could finally watch her paint. She felt admitted in a mysterious magic show, where she could gasp at the artist's dexterity. Lucy couldn't draw. She tried many times, but it wasn't her thing. She preferred to write. She loved to make a scene come alive with words.

"What are you doing?"

"I'm sketching."

"Why aren't you painting?"

"I can't paint directly without a sketch."

"…is this going to be long?"

"Are you going to talk the whole time?"

"Why are you so grumpy, I'm trying to understand!"

Lucy definitely wasn't one to paint. Instead, she took her notebook that day, and started to write, next to Natsu who was still sketching. The artist glanced at her from the corner of her eye. She was very curious about the secret stories of her roommate.

One day, Natsu put her arms around Lucy's shoulder to finally see what she was writing. Lucy was proud of her stories, but she never allowed Natsu to read them, because she knew she would make fun of her. She loved to write fairy tales…and she remembered Natsu's reaction when she heard one on their first day together.

From now on, when Natsu painted, Lucy would write for a few hours, in silence next to her. Lucy liked those moments, it reminded her of peaceful days with her mother, before she got obsessed with her wedding like her father.

Days passed quickly like this. The girls started to be friends, and learned to trust each other. Lucy would often cook for both of them now, and even if she sometimes burned the fish, her roommate still appreciated the intention.

Natsu now helped her to put her corset on and off, since Lucy hadn't stopped wearing them…despite her friend's multiple offers to lend her pants and a bra. Every time Natsu's fingers brushed her back when she tugged on the clothes to unlace it, Lucy felt weird. It wasn't like when her maid Virgo did it. Lucy then thanked Natsu and always asked her to turn around while she changed. She was very shy with her body, unlike her new friend.

That was probably the worst about her. Natsu felt absolutely shameless about nudity. When it was sunny outside, she would go take a nap next to the lake, only wearing panties. And the meanie couldn't help laughing at Lucy's shrieks when she saw her by mistake. She understood that she was confident with her body, after all, Natsu had a very nice figure. But that wasn't a reason to show herself like that!

And then the stripper called her weirdo…

"Lucy I have to go."

Lucy stopped writing and looked at Natsu in surprise. She was wearing a long black cloak with a hood. Only her long pink hair could make her recognizable.

"Remember, I told you we're running out of food? My dad sent a carriage with food supply, I have to meet the owner outside in the forest."

"Why can't he come here directly?"

"Because he doesn't know how to find the tower. Only me, my family and my father's personal soldiers –the ones who brought you there- know where it is. That's the purpose of this place."

Lucy frowned but didn't comment. "When will you be back?"

"In five or six hours."

"Can't I go with you?" she asked hopefully. Natsu blinked, not expecting this from the princess, then grinned.

"Nah you can't. What if you escape, huh? What a good drag- …keeper I'd be!" she laughed.

"You know I could have escaped a long time ago, just using the stairs, right?" Lucy smirked. Natsu bent to her face level, invading her personal space like always.

"I know, but you'd miss me if you left."

Lucy turned her face, feeling weird again. "What if the prince arrives? There's no dragon to welcome him, and no annoying pinky to throw him paint over the window or teach him how to move his hair L'Oréal style."

"You can pretend to be Rapunzel and tell him to come back when your hair is long enough."

"Pfff that wouldn't work, everyone knows Rapunzel, and I don't look like her at all. She's way more pretty than me."

Natsu clicked her tongue. "I doubt that." she smiled then walked away, leaving Lucy blink and blush on her spot. "You'll probably be sleeping when I come back. See ya!"

Lucy looked through the window until she saw Natsu disappear in the woods. She was starting to be annoyed with this weird sensations she felt sometimes around the girl. She thought she would get used to her ways by now…

The princess rubbed her sleepy face and stared at the bed. The empty bed. Natsu free. She grinned mischievously. She was finally able to leave her couch… Natsu would probably be angry. She hadn't allowed Lucy to sleep there yet. Not that she bothered actually. The bed was large enough for two, but…it felt…weird again to sleep in the same bed as Natsu. Lucy had never shared a bed with anyone.

After eating and wasting twenty minutes getting out of her dress, Lucy finally dived in the warm covers. Oh, she understood now why Natsu kept it all to herself… That was the most comfortable mattress and blankets Lucy had ever tried. It smelled good too. Lucy nuzzled the pillow, inhaling Natsu's scent. She smelled so different from all the nobles she met. They all used perfume. Even her mother. Natsu didn't smell like perfume. The pillow smelt like her. It made the blonde feel safe.

Happy joined her, snuggling on the mattress next to her. She stroke him for a few seconds, then closed her eyes. She fell asleep instantaneously…

…and woke up when a cracking noise resonated in the room. Lucy jolted in the bed, curling the blanket around her. She could tell it was late now. The moonlight was pouring throught the window. Nothing looked abnormal, but she felt it in her guts… Was it instinct ? Suddenly a shadow appeared on the wooden floor…

Lucy tried to shrink herself in the corner of the bed, keeping an eye on the shadow that moved and grew wider… It looked like a giant bird getting closer to the window. Her heart beated so fast in her ribcage she thought it might break it. She was paralyzed…was it a monster? It wasn't normal anyway. And she couldn't move.

She started to breathe heavily as she saw the moonlight hidden more and more by the shadow… The light disappeared, and Lucy thought she would have a hard attack. She closed her eyes, waiting for death. Something cracked again in the room. She screamed when she felt something shaking her.

"Lucy! Lucy, relax, it's me!"

Lucy opened her eyes. A dark hooded figure was standing in front of her. She saw a flash of pink and dark blazing eyes looking at her worriedly. Lucy deeply breathed in and out. Natsu was back.

"How did you appear out of nowhere?" Lucy let loose of the blanket to sit in the bed.

"Magic!" she joked. She took her cloak off –why the hell was she naked underneath?! - while Lucy realized she'd probably get unhappy to see her in her bed. She started to get up but Natsu put a firm hand on her shoulder. "What are you doing?"

"I'm…going back to the couch… ?" she hesitantly answered.

"Pfff, you weirdo. You'll get cold and sick if you sleep there now. Get back to bed."

Lucy didn't protest and collapsed on the mattress, yawning loudly. She peeked an eye open and saw Natsu's dark figure illuminated by the moonlight. She looked so majestic and beautiful…and still naked. She could perceive her feminine body in every angle. She wondered if the skin of her taut belly was soft to the touch.

For the first time, Lucy realized that she felt flustered at this sight…and that she liked it. She buried the feeling in her hazy brain and closed her eye, waiting for sleep to take her.

Natsu soon joined her under the blanket, after she'd put some panties and night shirt on.

"Sorry I scared you." she whispered. Lucy only hummed in response. She was already half way to the dream world.

A/N : there you go with chapter 1! Next time, you'll hear more about Natsu and her past :)
