The Happiest Days of Our Lives

Summary: For 24 hours, Natsu and Gray must endure the sweetest temptation. [NaLu] [Gruvia]


Part I – Young Lust

The moment Lucy's back was turned, Natsu hit the road.

To him, the solution was simple and quite obvious: if Lucy was going to be weird for 24 hours, then he'd just avoid her for 24 hours.

As soon as he bolted out of Fairy Tail, he began formulating a master plan since there was no way he was going to hang around that Lucy. He scratched his head as he sank into the cushions of Lucy's couch because man, all this thinking made his head hurt and he really needed to relax. Wait, what was he trying to do again? Oh right, avoid Lucy.

Suddenly, Natsu snapped back up and looked around him. Damn it—of course he ended up right back at her place! He couldn't stay there, not when she could be coming home at any minute! Hastily, he wracked his brain, trying to figure out where else he could go, but the only thing that came to mind was to go find Lucy.

Natsu groaned. Was there anything in his day that didn't revolve around that stupid blonde?

His stomach growled, stealing his attention. Ah, of course! When he wasn't hanging around Lucy, he was stuffing his face with delicious, yummy food!

His mouth watered before he stood up abruptly, ready to dash back into Fairy Tail—until realization dawned upon him. He couldn't just go waltzing back inside, not with Lucy still there! Aw, but he was so hungry…

Deciding to utilize his super amazing powers of stealth, Natsu crept along the wall of the guild, keeping an eye around him. If he remembered correctly, the kitchen back door should be coming up soon. His hand felt along the wall until it found a door handle, causing a wide grin to spread across his features as he opened the door and slipped inside.

Instantly, his nose was flooded with the delicious aroma of baked goods lying all around him. The sight was beautiful, too beautiful to describe with words.

There were pastas and meats and cookies and cakes and oh man, he just didn't know where to start! He picked up a mutton leg and sniffed it, sighing in content before bringing it to his mouth—

"Natsu!"

The boy jumped, whirling around to find Mirajane, scowling disapprovingly and tapping her foot. She snatched him by the collar of his vest, tearing him away. The poor boy struggled, stretching his neck to take just one bite—but Mirajane jerked her arm, pulling him out of the kitchen.

She dragged the whining boy back out into the guildhall, where his cries were instantly drowned out by Lucy's loud wailing. He winced at the sound, his stomach churning with guilt. He never meant to make her cry, he just wanted her to stop being so weird…!

Mirajane released his vest and approached the crying girl, sending Natsu a menacing glare that made him recoil in fear.

"Shh, it's okay," she murmured to Lucy, rubbing the girl's back soothingly. "Look, here he is!"

Lucy sniffled, shifting her brown eyes to Natsu as he smiled uneasily, giving her a small wave.

"Uh, hey Luce," he said nervously.

"Natsu, don't you have anything else to say to Lucy-chan?" Mirajane asked, placing her hands on her hips.

Lucy stared at him, pouting as she wiped the tears from her eyes.

"Uh…" the boy mumbled, scratching the back of his head. "Don't cry, Lucy! I didn't leave! I just went to get you, um…" He hastily glanced around the room. What did girls like?

Mirajane cleared her throat, nudging her head towards a flower vase nearby.

"Oh!" said Natsu. "Here, I got you this!" He quickly snatched the flower vase and promptly dumped out the flowers. Flashing an apologetic grin, he presented the vase to the crying girl while Mirajane smacked her forehead.

Lucy glanced from his face to his hands before her eyes widened. "For me?" she asked softly, taking the vase from him.

He nodded, "Yeah, of course!"

She blushed, cupping her cheek. "Natsu… is this a gift for our date?"

Natsu flinched. "Date!? That's not—" Mirajane nodded furiously while Lucy looked ready to burst into tears. "—I mean, yeah, sure! Whatever you want! Just don't cry, okay?"

"Yay!" she squealed, engulfing him a tight hug that effectively choked him. She released him a moment later, giggling to herself as Natsu gasped for air.

"I have to go get changed!" She waggled her finger and winked, "No peeking, okay? Unless you really want to~"

He blushed, "O-Of course not!"

Lucy laughed, pressing a kiss to his cheek before dashing away.

The boy rubbed his flushed cheek, flustered, before heaving a sigh.

Mirajane watched Lucy leave before turning towards Natsu, frowning disapprovingly as she crossed her arms over her chest. "How could you leave her like that?"

The boy jerked at her accusing glare. "Well, you saw her! She's being so weird!"

The barmaid sighed, shaking her head. "She was so heartbroken when you disappeared on her, poor thing. This potion is making her hyper-sensitive, so you need to be extra careful, okay?" Natsu pouted in annoyance while Mirajane tapped her chin pensively, leaning her weight on one leg.

"You know," she began, "I don't think this potion would be so potent if Lucy didn't feel so strongly about you."

Natsu's eyebrows shot up as a blush crept on his cheeks. "What's that supposed to mean?!"

Mirajane prattled on, musing to herself. "You two are very close… but the potion is definitely bringing out romantic feelings. Could it be extracting a person's innermost desires? Or revealing hidden feelings?" She peeped, covering her mouth with her hands. "Best friends falling in love? So romantic!"

Natsu twitched, spluttering nonsense while Mirajane swooned.

He sighed heavily and slumped into a nearby chair, wishing Mirajane would stop talking nonsense. "Why can't Lucy just go back to normal?"

"Oh, so you don't like her being all over you?" Mirajane asked with a sly smile.

His face reddened. "No way! She's such a weirdo!"

Mirajane's smile grew, making Natsu instinctively lean away.

"Why are you looking at me like—?"

"Oh Natsu~!"

The boy tensed at the giddy tone coated in sweetness, craning his neck over his shoulder. His eyes practically bugged out of his head.

There Lucy stood, blowing kisses at him in a black dress that hugged her curves like a second skin. Lined with a white ruffled trim with a bow right below her cleavage and a white belt around her waist, the dress left little to the imagination with the low cut and short length.

Steam shot out his ears. What was he supposed to do with her looking like that?

"Speechless?" Lucy teased, swaying her hips as she walked towards him. She leaned close to his face and Natsu swallowed, catching a strong whiff of her sweet perfume while forcing his eyes not to stare at her chest. Lucy giggled behind her hand, swiftly kissing his cheek. "How cute!"

"Can you stop doing that?" he grumbled, wiping her lip-gloss from his blushing face.

Mirajane smiled merrily, waving goodbye. "Have fun!"

"Oh we will," Lucy murmured, walking her fingers up Natsu's chest.

He shuddered, his face paling. Just what did he get himself into?


Together, Natsu and Lucy walked through the streets of Magnolia Town, Lucy swinging their interlaced fingers and humming while Natsu looked too eagerly at the clock every few minutes.

Lucy sighed happily, snuggling into Natsu's shoulder. "You're so sweet, taking me on a date."

Natsu gulped, laughing uneasily. "Yeah, sure."

"What did you have in mind first?" she asked, running her hand down his chest. "A romantic boat ride down the river? Or dinner under the stars?"

"Uh…"

"Or…" she purred, moving in front of him and leaning close to his ear, "we could skip all that and go to my place…"

Natsu tensed, grabbing her wrists and stepping away from her. "Dinner! Let's do dinner, yeah. Food is super good like man Luce are you hungry or what?"

"Hungry for you~"

She nibbled his ear, making him shiver before he pushed her back. "Uh, no no, how about real food, you know? The stuff normal people eat when they're hungry?"

Lucy pouted. "But I really really want to tear your pants off with my teeth."

Natsu's eye twitched. "Lucy—"

"Look, this dress is really easy to take off, see?" She slipped one strap over her shoulder, making the boy flush as he hastily snatched her wrists again.

"Don't do that!" he spluttered.

Lucy blinked innocently, watching a bead of sweat roll down his temple. "Natsu, you're sweating… want me to lick it dry?"

His face turned beet red. "Sh-Shut up, stupid!"

"Aww, is my little dragon shy?" she cooed, pinching his cheek.

"Am not!" he shouted, whisking his face away and fixing his scarf.

"Prove it," she murmured, stroking his jaw. He scowled at her, only for the anger to quickly dissipate when she tilted her head and batted her lashes, tempting him. "Prove it to me all night long…"

Her touches were soft, provocative and so unlike the Lucy he knew. They elicited strange new sensations that ignited a dormant flame in him.

His eyes narrowed, his voice dangerously low. "Stop it."

She flashed a coy smile. "Make me."

She knew damn well he never refused a challenge.

His gaze fell to her lips, recalling how soft they were against his. Slipping into a trance, he decided he wouldn't mind sinking into the intoxication of her lips again.

He grabbed her slender waist and pulled her to him, eliciting a gasp. She closed her eyes as he leaned towards her, his mouth mere inches from hers—

"Natsu and Lucy sitting in a tree~"

Natsu looked above him, finding Happy snickering behind his paw.

"Shut up, Happy!" Natsu growled, jumping to catch the cat while Lucy giggled.

Happy dodged him, flying aimlessly around their heads. "You look so pretty, Lucy."

"Thank you," the girl replied, giving a small curtsy. "Natsu and I are on a date."

"Finally!" exclaimed the exceed.

"What's that supposed to mean?!"

Lucy tugged on his vest. "Natsu, look!"

He followed her gaze, finding a popsicle stand with various flavors assorted neatly by color. He blinked, but before he could say anything, she dragged him by the arm as Happy followed innocently behind.

"That one please," she said, smiling radiantly as she pointed to a yellow popsicle. The vendor handed her the cold treat, echoing her happy smile. "Thank you!" she said cheerily. Whirling around, she looked at Natsu with bright brown eyes. "Let's go!"

She took his hand and led him down the street. The boy glanced at the clock tower and sighed, letting himself be pulled along. Lucy happily stuck the popsicle in her mouth, closing her eyes and giggling in content. Natsu rolled his eyes; who the hell liked ice on a stick so much anyway?

"Mm," she hummed. She pulled it out of her mouth with an audible pop, oblivious to Natsu stiffening beside her. "Tasty!" She glanced at the boy. "Want some?"

He whisked his head away, mumbling, "No!"

"You're not a very fun boyfriend, Natsu," Happy sniggered, buzzing around the couple.

"You're not helping!" he shouted.

"But Natsu, it's so good…" she murmured, her voice slow and sensual. She lapped at the juice melting off the sides before swirling her tongue around the tip.

Natsu stared at her with wide eyes, suddenly feeling very, very hot.

Lucy locked eyes with him and gave the dirtiest moan, instantly draining the color from his face.

Meanwhile, Happy blinked, oblivious. "Why are you making weird noises, Lucy?"

The girl ignored him, sticking the Popsicle deep inside her mouth before pulling it out slowly. Natsu swallowed, slapping his hand over Happy's eyes.

"Hey! Natsu!"

Lucy smiled seductively, keeping her eyes trained on him as she licked from the base to the tip.

Her tongue swept over her upper lip as she moaned once more. "So good…"

Natsu tugged on his scarf. Maybe he could use one of those ice stick things because damn, when did the weather get so hot?

"Natsu! I can't see!" whined Happy, struggling under the dragon slayer's grasp.

Lucy sauntered towards him, wrapping her arms around his neck and pressing her voluptuous chest against his.

"Do you want a taste?" she asked softly.

Her words were mute in his head, his attention stolen by the glistening juice lingering on her shiny lips.

She smiled and sealed the distance between them, placing her lips against his. Natsu's hand fell from Happy's face to the back of her dress, pulling her closer.

Happy's eyes fluttered open, only for his face to redden at the kissing couple before him. "Eww!" he cried, quickly flying away.

Natsu grasped the back of Lucy's neck, kissing her harder. She moaned as his tongue brushed her lower lip before slipping inside.

She tasted sweet with traces of banana flavor lingering on her tongue as her fingers tangled themselves in his hair. His mouth slanted harder over hers, his teeth nipping her lip before something cold hit the back of his neck, making him flinch.

Juice from the popsicle trickled down his back, but he barely noticed, too enchanted with the girl in front of him as she giggled and tilted it away.

She gave him a pretty smile, running her fingers through his hair. "Did you like it?"

He looked at her, dazed with hooded eyes. "Yeah…"

"Yeah?" she whispered against his lips, kissing him softly. "Mm, you taste so much better…"

He stared absently for a moment before pressing his mouth against hers once more. Her lips were so addicting and he liked her pressed up against him, feeling her soft curves against his body with her fingers in his hair. It awakened a dormant aggressiveness in him that made him want to kiss her and touch her and feel the friction of her skin against his.

Lucy pulled away to breathe and his mouth wandered, traveling from her cheek to her jawline to her soft neck. She moaned softly, tilting her head back as his tongue brushed against her creamy skin.

"Natsu…" She made a little noise when he sucked on her neck. "Let's go."

He lifted his head and looked at her, entranced. Lucy smiled, grazing her fingers down his cheek and planting a light kiss. His mouth chased hers for another but she leaned away, smiling at his confused frown.

"You want more?" she whispered.

Dazed, he nodded.

Lucy laughed softly, lacing her fingers through his and pulling him along. "So cute. Come on."

Natsu stared blankly at their linked hands.

"…Okay."
