Rated M for sexual themes.

Summary: Fruits Basket crossover. Lucy is in for a surprise when she stumbles into Natsu and finds out that he transforms into an animal of the zodiac.

Cursed

Lucy didn't know much before about her classmate, Natsu Dragneel. She knew that he was friends with her best friend, Levy, that he was a distraction in class, and that there wasn't a day that went by when he wasn't sporting his signature, scaly scarf. She also knew that he was drop dead gorgeous with his unruly tufts of pink hair, his mesmerizing dark orbs, and his mischievous grin that could stop the whole room. Other than that, the boy used to be a mystery to her.

Key word being used to.

Now, she was just stumbling across his greatest secret.

After class had ended, Lucy headed straight for book club, just as she did every Thursday. The girl loved book club more than anything. It allowed her to read new novels she never heard of before, led her to Levy, and even gave her inspiration for stories of her own. It was what she looked forward to every week.

Only this week, fate had more interesting things in store for her that Thursday.

After realizing that she forgot her bag, Lucy rushed back to the classroom, urging Levy to go without her and that she'd catch up. Hastily slipping past lingering students, the girl didn't waste even a second before throwing open the door and rushing inside, only to slam into something warm and firm.

Next thing Lucy knew, there was a puff of smoke and she was falling forward. She fell to the floor with a loud thud.

"Ow," the girl mumbled to herself. She sat up, rubbing her forehead. That was sure to leave a mark.

Just as she was about to get up, a muffled sound caught her attention. Glancing around the room, she searched for the source of the noise, only to find that the room was empty save for herself. Still, she could hear the faint voice coming from somewhere nearby.

Shifting to get up, she heard a sharp intake of breath.

"Will you get offa me already!?" a voice shouted, the sound coming from beneath her.

Lucy jumped with a startle, slowly lowering her gaze to her legs, which were folded underneath her. Her heart stopped, the first thing she noticed being red scales. With a scream loud enough to wake all of Fiore, she jumped off of the creature and onto the closest desk.

Not wanting to lose sight of it, she carefully leaned over to find the creature- she still wasn't sure what it was- laying on its back. Its scales were a bright red. Its belly was yellow, a sharp contrast from the rest of it. Once she found the creature's legs, she knew that it wasn't a snake. It must've been some sort of lizard.

Lucy whimpered. Now she was stuck with some strange, possibly venomous lizard. She would call Levy to help her, but unfortunately her phone was in her bag, which was at her desk.

On the opposite side of the room.

The girl watched as the lizard flipped itself over onto its hind legs, standing at about a foot. She may not have been an expert in lizards, but she'd never seen one stand before.

"Oh Mavis," she breathed out, her voice hushed in fear. "Please don't jump, please don't jump, please don't-"

"I'm not gonna jump so calm down, alright?"

Lucy's brows rocketed upwards at the voice. It was familiar, the same voice she heard earlier. She could swear she recognized it from somewhere else.

"H-Hello?" she called out, her eyes trained on the door. Someone must've been outside the classroom or something because there was no way in hell the lizard was talking to her. Nope. No way.

But sure enough…

"Down here," it said.

Lucy felt dizzy as she trailed her gaze back to the lizard, who was now staring at her with what she assumed was an annoyed look. The fall she took must've knocked her out earlier. She was dreaming. That had to be it!

"Uhh, maybe you should get down from there," the lizard said. Judging from its voice, she assumed it was a male.

"What? So you can bite me? No thanks, I'm fine up here," Lucy replied.

"You don't look so good. You're startin' to sway. I think you're about to pass out."

"Even though this is just a dream, I'd still prefer not to get attacked. I'll take my chances."

"I always had a feelin' you were weird, but now I know for sure you are."

Lucy arched a brow. "Wait, what do you mean by always?"

The lizard sighed before using his claws to close the door to the classroom.

"I'd give it about five more seconds," he said.

"Give what five more seconds?"

Suddenly, a puff of smoke surrounded the lizard. A shrill scream bubbled up to Lucy's lips, caught off guard. When the smoke died down, she found that she was in for yet another surprise.

Standing in front of her was none other than her classmate, Natsu Dragneel.

And he was naked.

That was all Lucy needed to send her off the edge. Her lids grew heavy, her eyes rolling in the back of her head as she wobbled on shaky legs. She could feel a cold gust of wind hitting her body as she fell forward.

"Oh shit!" she heard Natsu say right before she crashed into a firm surface, hot to the touch.

They fell back onto the floor, Lucy on top of him once again. That same puff of smoke appeared once more, Natsu having turned back into a lizard. He gave a pained yelp, which helped Lucy get out of her hazy daze.

"How many times are you gonna crush me!?" he said, trying to squirm out from beneath the blonde.

Lucy slowly moved off of him. Her mind was working on overdrive, trying to put the pieces together and figure out just what the hell was happening. It had to have been a prank of some sorts. She'd seen many talent shows that featured magicians able to pop up out of nowhere. Perhaps that's what he was doing, replacing himself with a lizard.

Yeah, that made sense.

"My tail!" she heard Natsu shout. He held his tail in his claws. It was bent weirdly, probably from being pressed underneath her. He turned an angry gaze on her. "This is your fault! I told you to get down from there! I knew you were gonna pass out!"

Lucy's face etched with fury at his accusation. "My fault? You're the pervert doing magic tricks and replacing yourself with a lizard!"

"Okay one, I'm not a pervert. That's Gray. Two, I'm not a lizard. I'm a dragon, got it? And three, I'm not a magician. This is just a curse."

"Curse?"

"It's a long story. For now, I need you to stop yelling. Someone's gonna hear you and come in here."

"Good! I don't want to be in the same room as a lying pervert!"

"Oi! Quit callin' me that! I'm not-!"

A puff of smoke appeared yet again, leaving Natsu naked in his human form.

"Okay, I see why you think this would make me a pervert," he said, holding his hands up in surrender to keep the girl from screaming. "But I can explain."

Lucy's eyes went wide, her face set ablaze as she stared at the bare man in front of her. Her gaze moved on its own, glazing over his abs and down to his-

"KYAAA!" she shouted, slapping her hands over her eyes.

Natsu winced at the volume of her voice, quickly slapping his hand over her mouth. Of course, this only freaked her out even more. She screamed against his palm, thrashing around before biting his hand. With a yelp, he pulled his hand back.

"You just bit me!" the boy shouted, glaring at the blonde.

"You deserved it!" Lucy retorted, making sure not to remove her hands from her eyes. "Just put your clothes back on, pervert!"

A vein ticked in Natsu's forehead after being called that again. Muttering incentives to himself, he hastily threw on his clothes. Wrapping his scarf around his neck, he gave a relieved sigh.

"You can look now," he said, watching as Lucy shook her head.

"I'm scared you're going to flash me again."

"I didn't flash you! It wasn't my fault!"

"You really expect me to believe that?"

Natsu sighed, running a hand through his hair. "Look, I'll explain everything, alright? Just come with me."

Lucy parted her fingers slightly, peeking at the boy to make sure he was really dressed. Only after did she nod.

"Fine. But if you even think of lying to me or flashing me again, I'm going straight to the police!"

"Yeah, yeah. Let's go."

Natsu led her to an empty, rundown park. He sat on one of the picnic benches, gesturing for her to take a seat as well. She refused.

"You know, now that I think about it, I probably shouldn't have followed a boy that just flashed me to an abandoned park," Lucy said.

"It's not like I'm gonna do anything to you," Natsu replied with a shrug. "I just need you to promise you won't tell anyone what you saw today."

"And why the hell should I promise that? What you did was sexual harassment, you know."

"I already told you it was the curse!"

"What curse?"

Natsu groaned. "It's called the curse of Fairy Tail. There are twelve of us. We each represent one of the signs from the Chinese zodiac. Whenever we're hugged by someone of the opposite sex, we turn into our zodiac form. I'm the dragon."

Lucy glared at the boy in front of her. "You really expect me to believe that?"

Losing his patience, Natsu stood up from the bench, moving right in front of her. "Hug me again and find out for yourself."

A blush rose to her cheeks. "N-No way! I don't need to hug you to know that you're lying!"

"Fine, then let's go find Levy."

"Levy-chan?" Lucy asked, arching a brow. "Why do you want to find her."

"She's one of us. Duh."

She would've been annoyed by his 'duh' comment if she wasn't so curious.

"Alright, fine," she said, planting her hands on her hips. "If Levy-chan says you're telling the truth, I'll forgive you for what happened. If not, then I'll beat the hell out of you."

His lips curled into a mischievous grin. "You really think you can?"

"I have a pretty mean kick."

"Now I kinda wanna tell you I'm lying so that I can see just how strong that kick of yours is."

"Keep annoying me and you'll find out."

Making their way back to the school, Lucy popped her head into the room where the book club met up. After gaining Levy's attention, she waved for her to come outside.

Closing the door behind her, Levy arched a brow finding that Natsu was with Lucy. The two never spent time together.

"Where were you, Lu-chan?" Levy asked. "Book club is almost over!"

"We needa talk," Natsu said. "C'mon."

The trio headed back to the classroom. Natsu closed the door behind him and locked it.

"So, I might've messed up," he said, turning to meet Levy's gaze.

"What did you do?" the petite girl asked.

"Lucy found out our secret."

"What?"

Lucy breathed a sigh of relief at Levy's confused expression. Just as she thought, Natsu was lying.

"I knew you were lying! I'm so going to beat the-!"

"How did she find out!?" Levy shouted, cutting the blonde off.

Lucy whipped her head towards the other girl. "Wait, what? You mean he was telling the truth?"

Levy chuckled awkwardly. "Yeah, he was. You must be shocked."

"B-But we hug all the time!"

"The curse only works if the hug is from someone of the opposite sex."

Lucy's mouth parted as she leaned against the wall for support.

"No way," she breathed out.

Natsu shrugged, his arms crossed behind his head. "I'm surprised you didn't find out sooner."

"What do you mean?"

"I mean, you hang out with a bunch of us. I figured someone woulda told you by now."

"What!?"

"He's right," Levy said. "Well, about you hanging out with a bunch of us. Not about us telling you. We aren't dumb."

"Wait, who else is like you guys?" Lucy asked. Her mind was short-circuiting.

"Well, there's Erza, Juvia, Cana, and Mira. All of us are cursed."

"And Gray, Gajeel, and Jellal," Natsu added. "But you don't hang out with them."

"Aren't there supposed to be three more?"

"You wouldn't know them. They're older than us."

Lucy brought her fingers to her temples. She could feel an oncoming headache.

"So you guys really turn into animals when you're hugged by the opposite sex?" Lucy asked, still unable to completely wrap her head around it.

"Yep," Natsu answered nonchalantly. "And you're the only one outside of Fairy Tail who knows our secret!"

Lucy faced Levy. "What zodiac sign are you?"

The other girl pouted. "I'm the rat. Sadly, I'm not one of the cuter animals."

"It makes sense though. Rats are supposed to be intelligent and resourceful. What about everyone else?"

"Erza is the monkey, Juvia is the rabbit, Mira is the goat, and Cana is the horse."

"Gajeel is the ox, Gray is the tiger, and Jellal is the snake," Natsu added.

"And you're the lizard," Lucy teased, stifling her laughter.

He glared at her. "Dragon, okay? I'm a dragon!"

"Pretty small for a dragon."

"That's only because a real-sized dragon would destroy everything!"

"Oh, so you can change your size?"

"Well, no but-"

"You're a lizard."

"Yeah? Well you were pretty scared of this 'lizard' earlier! You shoulda seen yourself! You were screaming at the top of your lungs! You even jumped on a desk! That gave the perfect view to your underwear, you know?"

Lucy blushed in embarrassment, chasing after the cackling boy. She was so going to wring his neck if she ever caught up to him.

"I knew you were a pervert!" she shouted.

"Stop callin' me that!" Natsu shot back.

Levy sighed, rubbing her temple as the other two bickered. "Well, I'm going to go find Erza and tell her about this… development. I'm sure we're in for an earful." Seeing that the other two were too caught up in their argument to hear her, she shrugged before heading out.

"Stop running so I can kick you now!" Lucy demanded.

Natsu laughed, his cheeks starting to hurt with how wide his grin was. "Gotta catch me first! What's wrong, Lucy? Can't catch up to a lizard?"

Getting fed up, Lucy cut him off and tackled him to the floor, triggering his curse. By this point, she was starting to get used to the puff of smoke that accompanied Natsu's change in form. Wrapping her hand around his scaly abdomen, she gave him a smirk.

"Looks like I finally caught you," she teased.

Natsu huffed, a small wisp of fire slipping past his sharp teeth. "Yeah, yeah."

Lucy ran her finger over his scales. "You know, it's kind of cool that you guys change forms."

"Cool? It's called a curse for a reason, Lucy. It sucks. Every time a girl tries to throw themselves at me, I gotta think quick enough to dodge them or else I'm gonna end up on some researcher's desk while he cuts me up and tries to figure out why I change forms."

The girl shrugged. "That's true. But it also brings you guys closer together. Not to mention it makes you special."

Natsu stared up at the blonde, his eyes widening a fraction. "You don't think it's weird?"

"Oh, it's weird alright. But you called me weird too, remember? So I guess I have no room to talk."

The dragon grinned. "You are pretty weird. The weirdest person I know since you're so calm about all of this."

"I wouldn't say calm. I almost fainted earlier."

"Oh yeah. Then I had to catch you and you fell on me. You're pretty heavy, you know that?"

Lucy grabbed his tail with her other hand as she glared at him. "Don't make me rip you in two."

"So violent!"

"Only because you know how to annoy me."

Natsu laughed at her expression. Her cheeks were puffed out in annoyance as she narrowed her eyes at him. He was about to reply when the effect of his curse wore off. His body was engulfed in a puff of smoke as he morphed back to normal. He was left standing bare yet again.

Only this time, a hand rested on his upper thigh.

Lucy's face burned crimson as her gaze was immediately met with a part of Natsu she had never seen before. Swallowing thickly, she tried to force her gaze away. Realizing that her hand was on his upper thigh because of where she was holding him earlier, she tore it away with a squeal.

"I-I didn't mean to touch you there!" she shouted.

Natsu clamped his teeth on his lower lip, trying to stop his body from growing hard. Unfortunately, his attempts were fruitless. It wasn't his fault! There was a beautiful girl on her knees right in front of his groin and her hand was on his thigh for god's sake!

Lucy felt like she was on fire, the pit of her stomach coiling as the area between her thighs throbbed in arousal. She could see his cock growing hard in excitement, and even though she didn't have any experience in this sort of thing, she had heard enough about Cana's sexual endeavors to know what it meant.

"This is the second time I've caught you staring at me, you know," Natsu said, grabbing her attention.

Lucy flailed her arms around, her heart thrashing around her ribcage. She shot up to her feet and turned around in mortification.

"It's not my fault you change back so suddenly!" the girl shouted.

Natsu laughed. He wasn't the kind of person to get embarrassed easily, so he didn't let what just happened bother him too much. Instead, he got dressed.

"I'm dressed now," he said.

Swallowing thickly, Lucy turned to face him. Her eyes immediately dropped to the hem of his pants.

"And that makes a third time," Natsu teased with a heavy smirk.

Lucy groaned, heading to the opposite side of the room to grab her backpack- the catalyst for how this all began. Glaring at him, she headed for the door.

"I'm going home," she said.

Natsu laughed, following her out the door. "What? Sure you don't wanna go for a fourth look?"

"Shut up!"

"Oi, you don't have to yell! It's not my fault you're a pervert!"

Lucy groaned again. Something told her that she was going to be stuck with Natsu following her around from now on. In truth, she couldn't say that she minded.

The day was hectic, to say the least. Hell, she still wasn't completely sold that she wasn't just dreaming. Still, she was sure that her life was about to get a whole lot more interesting with Natsu around.
