So this is an older fan fiction I dug up in my computer. I do enjoy making lemons :3 And as much as I LOVE Gajeel and Levy, I will admit Natsu and Lucy come up as my second fav fairy tail couple! Anywho, please enjoy!

Happy, Lily, and Charle all sat together, watching their dragon slayer companions.

"I'm so glad Wndy isn't old enough yet," Charle sighed, "I don't know what I'd do with the girl,"

"Yeah," Happy let out an exasperated sigh, "Natsu can get so bad we have to leave on missions so he can let out some steam. Otherwise he fights with everyone in the guild,"

"Isn't that normal?" Lily said, looking at Happy more than a little confused, "What's so different about now?"

"Haven't you noticed anything different about Gajeel lately?" Happy asked.

"Not really… He's been sleeping less but besides that… no…" Lily pondered, "Why?"

Charle and Happy laughed a little nervously, "You'll find out soon enough,"

Gajeel was leaning against the wall outside of FairyTail. He was trying to concentrate, to keep his mind off of certain things. But how could he? His skin felt like it was crawling. There was a heat under his flesh that desperately need to be released.

As he sulked, he noticed a familiar scent wafting his way. His eyes widened as a fresh wall of heat washed over his body.

'Not now!' he shivered.

"Levi-chan! You did so amazing!" Jet's voice rang from somewhere far off.

"And so smart too!" Droy chimed in.

"It's not a big deal guys," that familiar voice came from down the hill.

'Damn,' Gajeel growled. Maybe if he left now, he could be spared the madness about to cloud his mind…

"Gajeel?"

Gajeel physically jumped. He felt so on-edge. His eyes met with his little Exceed partner's. He tried his best to act as natural as possible.

"What's up, Lily?" he smirked crookedly.

"Is something wrong?" Lily asked rather abruptly.

Gajeel's smile faltered. He didn't think he'd have to explain his predicament to his Exceed friend. Actually, how could he?

Suddenly, he caught her scent again. It was as if every hair on his body stood on edge. She was sooooo close…

Movement out of the corner of his eye… a blue dress with an orange headband. His skin was crawling like it never had before. His mind was fuzzy. Suddenly, all he could think about was how much he had to have her, how much he needed that girl under him, calling out his name…

"Gajeel!" Lily yelled, getting his attention. But the look his friend gave him completely took him back. Lily received the most blood-curdling glare from Gajeel he could've imagined. And for what reason? He had no idea.

Gajeel looked over and watched Levi walk into the guild, and with the closing of the doors, so her scent vanished. It was like he'd just been doused with water. With a hiss, he sank to the ground, visibly shaking.

"Gajeel?" Lily inquired, "What's going on?"

"I'm going insane," the iron dragon slayer growled, rubbing his face with his hands, "And it's all her fault."

"Whose fault?" Lily was so confused.

"Look…" Gajeel sighed, finally deciding to confide in his friend "Because I'm a dragon slayer, I am part dragon in a sense. I have their fighting skills but… we share even more than that in common…"

"Oh?" Lily crossed his arms, "And what's that?"

"I guess you could say their seasons…" Gajeel received a blank stare from his friend, "I'm in heat,"

Lily was completely caught off guard. A sudden realization hit him, "So that's what Charle and Happy were talking about."

"Eh?"

"N-Nothing,"

"Anyway, usually its fairly manageable but…"

"Levi," Lily concluded.

Just her name sent shivers down Gajeel's spine. He growled something Lily couldn't quite catch and left, heading for the forest. Lily felt it best to leave him alone and went to rejoin Charle and Happy in the bar.

Natsu was sitting on a branch in the middle of the forest. His senses were on high alert, adrenaline pumping through his veins with no way to be released. God he hated this time of year. Flames were roiling in his stomach. All he could think about was his intense desire to hit something, burn something… KILL something.

A shiver went down his spine.

Maybe if he asked Lucy to research the mater, she could find a potion to calm his senses. She was so smart… and pretty…

A growl escaped his lips.

'No! Don't think like that!'

He knew better than to think of a woman when he was like this. Feelings would develop that he couldn't control. Thus why he usually went on a job that would take a long time far away. Something that required someone to take out, or something he could destroy. But this time there was nothing that would work. And so, he isolated himself in the forest, praying no one would come looking for him.

Suddenly, a familiar sent hit him like a ton of bricks.

"Gajeel…" Natsu growled, jumping out of the tree. Rage filled his own being. What was he doing here? Who the fuck did he think he was? Trespassing into HIS territory?

He couldn't stop the animalistic thoughts that were surfacing in his mind A fire rolling in his belly, threatening to spill over any second, Natsu charged into the direction of Gajeel's scent.

When he saw the Iron Dragon Slayer standing in the clearing ready for a fight, Natsu charged.

"What the fuck do you think you're doing here?!" Natsu lunged, landing a solid flame-covered hit on the Iron mage's chest, sending him flying backwards.

"You looking for a fight, Salamander? 'Cause I brought you one!" Gajeel stabbed at him with his arm now turned to a sword. Natsu dodged, landing a good one on Gajeel's face.

In the haze of Natsu's mind, he realized Gajeel must be feeling the same way, thus why they were both locked into such a bloodlust-filled frenzy. The primal part of him didn't care, however and that part of him completely overpowered any sense he could've had. Fighting almost as if it were for his life, Natsu hit Gajeel with another fire-filled punch.

Natsu wound his fist back to hit Gajeel when suddenly he heard something gin the distance…

"Natsu?" a voice called from the forest and it made him go unnaturally still, "Natsu! Are you here?"

"Lucy…" heat seemed to flush through his entire body. God, the heat… the need… He could smell her, she was so near!

"Geehee," Gajeel sneered, making Natsu snap his head around to glare at him, "Is that what she is to you?"

"Don't you dare bring her into this," Natsu growled, grabbing Gajeel by the neck and slamming him against a nearby tree.

"You may be able to hold yourself back," Gajeel growled menacingly, "But I can't…"

Natsu tightened his grip around Gajeel's throat. His vision war red with fury.

"She's MINE," Natsu hissed out, low and feral.

"I don't see your mark on her," Gajeel choked out.

"Maybe I'll change that," he growled, dropping Gajeel and stalking off in the direction of her voice.

"Natsu! C'mon! I'm worried about you!"

A cruel smile found its way to his lips. 'Silly girl, you should be more worried about yourself.'

"Natsu!" Lucy called out one last time. "Maybe I should've listened to Happy and Mirajane and just left him alone. But I've never known Natsu to be like this. He never isolates himself from the guild,"

"Oh he usually does this around this time of year," Mira had told her, "No one really knows why, he just does. He always seems tired when he gets back though. Don't worry so much, I'm sure he's fine."

Happy's answer and been a little more vague than that. For some reason Lucy just couldn't shake the feeling that something was wrong.

"I guess I'll just leave then," she sighed and turned around. She walked a little while before getting the sensation that she was being watched… or followed. Cautiously, she looked around. She couldn't see anything but still the feeling persisted.

"Natsu?" she called tentatively.

"You shouldn't be here, Lucy," she heard his voice but couldn't see him. It had begun to darken outside and a chill crept down her spine.

"I was just making sure you were ok." she said, a little miffed, "But I'm ok with leaving now. I don't have the slightest idea as to why you'd want to stay out here. And for goodness' sakes would you come out?"

A growl reverberated from one of the trees and she finally caught sight of him crouched on one of the branches. He jumped down, landing lightly a few feet away. Lucy noticed the dark aura emanating from him as he straightened up. He gave her a look that chilled her heart.

"Natsu? Are you ok?" she said shakily.

He walked towards her, scales appearing on his skin. She noticed a large gash in his side that was bleeding profusely.

"Natsu! What happened?! You're bleeding!"

The dragon slayer didn't respond. As he approached, Lucy started backing away from him. He just kept giving her that same dark look.

"N-Natsu… you're scaring me," she stammered, backing against a tree. No where left to go.

"Natsu…" she said quietly, trembling now.

Natsu was going mad. Her scent was too much; his primal instincts were taking control of him. Surely she'd be smart enough to run, wouldn't she? But no, she backed herself into a corner. A smile pulled at his lips.

He put his arms on each side of her, digging this claws into the bark of the tree. Lucy's pace jumped a few beats and her eyes widened as she heard the tree groan against his strength.

'Yes,' he thought, 'Be scared. Run away.'

But he couldn't bring himself to stop. He leaned down, her scent completely intoxicating him. He could feel her pulse in her neck as he brushed his lips against her skin. His tongue slid down her neck, raising goosebumps where his tongue touched.

Lucy was truly scared. he could smell the fear scent being emitted from her pores. From the angle he was at, he could see nicely down the crevice of her breasts.

For a brief moment, sanity came back to him. Shaking, he pushed his forehead against the bark of the tree. He took in a shaky breath through his mouth and let out a low growl. Could he hold himself there if she ran away? His eyes squeezed shut.

"Run away Lucy," he growled out, fighting th animal side of him as hard as he could, "While you have the chance, I need you to go… NOW,"

"B-but… what's wrong with you?" she stammered, still too scared to move, "Is someone controlling you?"

"No," he chuckled darkly, "Its all me," His smile was wicked and it send a shiver down Lucy's spine. Natsu so desperately wanted to send more down her spine, and make some other places quake as well. He licked his lips, imagining what it would feel like to just throw her down right then and there. His skin started to crawl with the heat again.

'God, how much more can I take?'

"Natsu, please. Let me help you," she said shakily, "Is there anything I can do?"

he laughed, "You shouldn't have said that,"

"But wh-?"

Her sentence was cut off by a kiss. It was so full of lust and need she couldn't think straight. His tongue slid across her lips, coaxing a quiet moan from the celestial mage, allowing for a beautiful opening. His tongue invaded her mouth, claiming it.

Without a second thought, Natsu brought up a talon and ran it down her skimpy half-top, cutting it in two. Lucy shivered at the sudden cold and went to cover herself but he didn't allow it. In one simple motion he grabbed both of her wrists and pinned them over her head. She gasped as Natsu's lips left hers to kiss down her jaw, neck, collar….

"Natsu," she whispered, snapping him out of his lust-filled daze. She was shaking, but whether it was from fear or the cool against her skin he couldn't tell. He got a sinking feeling in his stomach as the sane part of his mind slowly started realizing what was going on.

But his dragon side still maintained its control on his body.

"Natsu, what are you doing?"

his mind was hazy. After all that and she still wasn't trying to get away? Was she paralyzed by fear or just too stupid to try and run?

'Or maybe she likes it…'

A growl left his lips and he released the mage from his grasp. Taking a deep breath and exhaling slowly, he desperately tried to calm his mind, to stifle the raging heat under his skin.

"I'mm sorry Luce," he was hoping he sounded like himself, "I'm not myself. This is why I left,"

"What's going on?" she asked quietly.

"I'd because I'm a dragon slayer," Natsu closed his eyes, concentrating on his explanation,"We do this once a year…"

The heat surged, making him stop.

"But why?"

"Because it's time to choose a mate," he felt his self control breaking once again, "It's never been this bad until…"

"until what?" Lucy couldn't process what was join ton fast enough.

Natsu was trembling with desire again, the sensation breaking up his thoughts.

He leaned close to her face, his blazing eyes locking with her large brown ones, "Until you,"

here eyes filled with surprise. Natsu himself had only just realized it. His feelings were undeniable, especially now. And now he wanter her more than anything.

"If you don't feel the same way," he growled, "You might want to go… soon…"

Lucy didn't know what to think. Did she feel the same way? She;s be lying if she said she had really wanted him to stop before. But seeing the tortured dragon slayer before her, she finally decided to take the risk. she could always deal with the consequences later right?

Without another hesitation, she kissed Natsu.

The fire that suddenly ignited inside of him he almost couldn't believe. He crushed her lips against his, his tongue thirsting for as much of her as he could possibly get. She's accepted it, and now he could finally let loose and entertain the thoughts that had been trying so hard to scratch their way to the surface.

With one arm he pulled the celestial mage against him, feeling her exposed breasts touching his chest. The other hand travelled down her spine, rewarding him with a shiver and moan from his companion. His fingers slid down to the crook of her knee and pulled her leg per his waist.

She could feel his hardening member pressing against her. Part of her was excited while the other part of her was terrified. This was all new to her. What if she did something wrong? What if she decided she couldn't do this What if he wasn't gentle with her?

She was so unprepared for all of this. But with each heat-filled kiss from her dragon slayer, her inhibitions were starting to slide.

Wait… HER dragon slayer?

Shivers broke her train of thought. His hand was making its way from her knee, up her thigh, her side, and finally grabbing her breast none-to-gently. She broke their hot kiss with a gasp. Immediately she felt his lips on her breasts, dissing them hungrily. With his thumb he rubbed her nipple in pleasure-filled circles while his tongue made its way to her other.

"Natsu!" she gasped as he licked her nipple, biting it enough to cause her to gasp but not enough to hurt her.

Natsu was fighting the urge to just throw her on the ground and take her. But the feelings he got from exploring her body he just couldn't believe. He felt his hand making its way to her skirt, running a single finger against the wetness of her underwear.

God… he could SMELL her desire!

His finger rubbed against her gently, making her grind her hips against his hand. He found her clitoris and rubbed his fingers in small circles around it, causing her to moan his name.

He loved hearing his name coming from her lips like that. Ne needed to hear it more. Wanted her to scream it into the night.

With a growl, he pushed a finger inside of her. She sucked in a breath and let out a lust-filled "Natsu". Just what he wanted.

He started sliding his finger in and out of her, feeling ht education of her walls pulling against his finger. He could feel his member twitch. The heat found its way back under his skin. This wasn't enough! He needed to feel his dick inside of her! Wanted to make her beg for him inside of her.

His thoughts suddenly dissipated. He felt her hand slip into his pants to grab his throbbing member. He heard her breath hitch when her fingers clamped around him. A smirk made its way to his face when he realized his size had surprised her.

He kissed her roughly as she began stroking his penis with her hand, he thumb sliding across his head. the sensations going through him were driving him mad! It wasn't enough! He needed more!

He let out another low growl as she ran her fingers down the vein of his dick.

'Damn!' he thought, 'She learns fast!'

"Lucy…" he moaned, his mouth finding her neck again, his tongue licking the smooth skin there. She was panting, the movements his fingers were making taking their toll on her senses.

Natsu couldn't take it anymore. Enough of the teasing, time to get down to business.

He pulled back his hand, receiving a dejected moan from his Lucy. Without missing a beat, he lifted her up and pushed her against the tree. He sucked on her nipple while his claws made short work or her underwear.

"Lucy," he growled into her breasts while pulling out his member.

She couldn't help the fear that was slowly creeping through her heart. He was so large and she was a virgin. She didn't think she'd be able to take him.

She felt him press his head against her heat. Just that alone was almost enough to send her over the edge. But he was pushing harder, fitting his head inside of her, then pushing against her…

"Natsu! Please!" she protested, feeling the pain increasing. Her cries were falling on deaf ears.

He forced the rest of him inside of her, making her scream. The heat crawling over his body intensified.

"Damnit Lucy!" he groaned, his claws digging into her ass, "…so tight…"

Lucy entangled her fingers through his hair, feeling herself trying to stretch around his dick. She could feel him throbbing inside of her, the need shining in his eyes.

Natsu started sliding out and she almost cried for him to stop. She cried out when he pushed back into her. She couldn't believe the ecstasy filling her body right now. With every thrust she was sent closer and closer to the edge. his skin was so hot against hers. She didn't even notice the pain from her back rubbing against the bark of the tree.

He started pounding into her even harder. She could feel the tension in both of their bodies swelling. She was going to go over the edge!

Gasping his name, she felt herself orgasm, her sight melting in a with haze of pleasure. After her, Natsu finally came as well. As he did, he bit down on her neck, tasting blood as his sharp teeth punctured her skin. She screamed from the pain and pleasure of it.

Both of them shaking, Natsu lowered himself to his knees, still inside of her. She was panting against his neck. Slowly, he released his grip from her neck, licking the two puncture wounds on her neck to close them with his saliva.

Now she was his forever.

He smiled, lifting the exhausted girl off of him.

"I'm taking you home, Lucy," Natsu whispered into her ear, taking in the scent of her hair.

"Are you sure?" she mumbled into his shoulder, "I thought you…."

"Trust me, " he smiled down at her, "I feel much better now,"

"Ok."

Lifting her into his arms, he started walking off in the direction of her apartment, very glad it was too late for anyone to be out.
