The Happiest Days of Our Lives

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


Part I – The Thin Ice

While Natsu's first instinct was to hide from Lucy, Gray's was the exact opposite. There'd be no point—the girl was like a bloodhound with her uncanny ability to sniff him out anywhere. Being on some weird potion made no difference.

He took a deep breath, keeping his hormones in check. Okay, he could do this. He just needed to stay in public, and the guild lobby was the perfect place to do just that. All the people around would hopefully help censor Juvia and, more importantly, distract him from doing anything stupid. Besides, he was used to brushing off Juvia's advances; how hard could it be to do it for another 24 hours?

"Gray-sama makes Juvia so wet."

He cringed. Okay, maybe it'd be harder than he thought.

"Could you let go a little?" he muttered grumpily, trying to pry her off as she squeezed the life out of his arm.

"Juvia wants you so much," she said breathlessly, biting her lip.

His eye twitched. Damn it—people were staring. "Enough, Juvia."

Instead, her hand slid down his arm and rubbed his thigh. "It hurts so bad, Gray-sama… help Juvia, please—"

He slammed his hand over her mouth, his face flushing furiously. "Stop talking," he growled through gritted teeth.

Juvia's eyes widened, only to shine in giddy glee as she lowered his hand. "Oh, Gray-sama's so sexy when he's angry! Say Juvia's name, please please?"

This is a nightmare, he thought, despairing over all the attention they were getting.

"I'm leaving," he muttered, standing up and kicking the guild doors open.

"To the bedroom?" Juvia asked eagerly, trailing after him.


He never minded Juvia's company. Well, he did when she first joined the guild, only because she was annoying with her "Gray-sama" this and "Gray-sama" that. But over time, he got accustomed to her always being around him. He liked how she always welcomed him when he returned from missions and how she'd ask how they went, listening with genuine interest as he'd tell her about how badly he crushed his opponent. The way her eyes would widen in awe made his pride swell.

That Juvia was the one he wanted around him, not this crazy, lewd nymphomaniac that he had to babysit for 24 hours because she was naïve enough to get doused in some stupid potion.

Gray scratched his head in frustration, unsure of what to do next. He was leading them aimlessly around town, trying his best to stay in public places for the sake of his sanity. To his great relief, she'd become surprisingly quiet and kept her hands to herself.

Casually, he glanced at her, finding her lost in her thoughts. Thank God, he thought, relaxing a little. If she stayed that way, maybe he'd be able to make it through the day without doing anything stupid.

But of course, the silence didn't last as long as he hoped.

"What's your favorite position, Gray-sama?"

Gray cringed. She couldn't possibly be talking about—

"For making love, Juvia means."

Damn it.

Gray ground his teeth together, refusing to answer. If he just ignored her, she'd have to drop the subject, right?

"Gray-sama? Hello?"

She leaned over from his side and peered up at him with large blue eyes that complimented her white sundress and made her look, damn it, pretty damn cute.

Her cleavage was on perfect display as she tipped forward to get a closer look. Fucking hell, why did she have to wear something like that today of all days? The front barely contained her generous breasts and the wind constantly blew her skirt up—why did it have to be so damn windy?—revealing the guild mark on her thigh and her pretty, pretty legs. Each time, it took more and more effort to tear his eyes away.

"Gray-sama?" she called sweetly, snapping him out of his reverie. He whisked his head away, keeping his gaze trained on anything but her. "Does Gray-sama have a favorite?"

"'None of your business," he muttered.

She gasped, her eyes instantly lighting up in excitement. "So Gray-sama does have a favorite?"

He flinched as a blush spread across his cheeks. "What! I didn't mean—!"

"Which one? You can tell Juvia! Juvia wants to satisfy every desire of Gray-sama!"

The problem was, she was his desire. The idea of her obeying his every command turned him on more than he liked to admit, and it created disturbingly vivid dreams that made him wake up panting and sweating in the middle of the night. And right now, she was just so willing, and he was so tempted. With a single word he could have her in his bed, and make those dreams a reality.

He tensed as she leaned too close, her hands on his shoulders with her lips by his ear. "Tell Juvia, Gray-sama," she whispered, sending an involuntary shiver down his spine. "Anything Gray-sama wants… anything…"

His body froze: anything he wanted.

Juvia sighed, fidgeting against him. "Oh, Juvia wants you so much—"

"Juvia-chan!"

Juvia glanced over her shoulder and Gray instantly exhaled, releasing a breath he didn't realize he'd been holding. Thank God, he thought—until he caught sight of silver hair.

Fuck. Of all people—

Approaching the pair was none other than Lyon, waving his hand and wearing charming grin.

"I wouldn't get too close to Gray," Lyon tsked, placing an arm over Juvia's shoulders and pulling her away from the red-faced ice mage. "You'll probably get sick."

"Sick?" Juvia repeated, blinking her eyes. "But… Juvia's already sick!"

Both boys stared while little hearts danced around her.

"Lovesick!"

Gray cringed while Lyon's face twisted in confusion.

"Can't you just shut up," said Gray, blushing madly.

"Don't talk to Juvia that way!" Lyon retorted.

"But Juvia wants the world to know how much she loves Gray-sama!"

"Juvia, you don't know what you're saying!" Lyon glared at Gray with accusing eyes. "What did you do to her?"

Gray scowled, "Me?! Why would I—"

"Gray-sama!"

The girl launched herself at him, flying her arms around his neck and crashing her lips on his. Gray staggered and flailed his arms, his words muffled against her demanding mouth while Lyon's eyes bugged out his head.

"Juvia, no!" cried the older man, watching in horror as Juvia moaned and ran her fingers through Gray's hair.

Gray grabbed her shoulders while Juvia tilted her head and kissed him passionately, melding their lips together and pressing her body flush against his.

He tried to pull her off, but his resolution was quickly dissolving as his mind began to wander. Her lips were soft, and felt pretty damn nice…

Suddenly, her mouth was yanked off of his, making Gray's eyes snap open.

"It's worse than I thought!" Lyon exclaimed, locking his arm around Juvia's waist as she struggled in his grasp, clawing towards Gray.

"Lyon-sama!" the girl whined.

Gray caught his breath in brisk pants as he wiped his mouth with the back of his hand. He coughed, trying to regain his composure. "Uh, thanks."

Lyon glared. "You didn't even try to resist."

"Because Gray-sama loves Juvia too!"

"I grabbed her shoulders—"

"To force yourself on her? I know you enjoyed it!"

"Gray-sama loves Juvia!"

"Shut up!"

"Juvia loves Gray-sama too! Very very much!"

"No!"

Lyon scooped the girl up bridal style, keeping a secure grip on her. She squeaked while Gray watched the way her skirt hitched up her thighs, making his chest tighten. "Juvia, Gray has done something terrible to you—"

"Never!" Juvia cried. "Except…" Her gaze lowered to her hands clasped together in front of her chest. "Gray-sama won't touch Juvia…"

Gray twitched while Lyon's cheeks turned pink. "Well… um, if you'd like to be touched, I could—"

"Don't you lay a finger on her," Gray snarled, clenching a tight fist.

"How dare you treat Juvia this way, Gray," Lyon scolded, clicking his tongue. He gave Juvia a suave grin while the girl blinked in response. "Don't worry, Juvia. I will satisfy all your desires."

Juvia's eyes grew large. "Lyon-sama…"

Gray seethed, growling menacingly low as his blood ran cold. Why was she looking at him like that? Did this potion make her feel overly affectionate for anybody?

She was his responsibility, not Lyon's. He'd be the one shouldering all her aggressive advances, not anyone else—and especially not Lyon.

First, he needed to get her out of Lyon's dirty hands. Forcing himself to calm down, Gray loosened his fist, standing up straight and tossing his hair away from his eyes.

"Juvia."

The girl whipped her head in his direction, looking eagerly at the ice mage. "Gray-sama?"

He winced inwardly, but there was no turning back now—a man's gotta do what a man's gotta do.

His lips lifted in a handsome grin as his head tilted, closing one eye in a charming wink. "You want to know my favorite position, right?"

"Position?!" Lyon roared. "What position, Gray?!"

Meanwhile, hearts appeared in Juvia's eyes. "Gray-sama!"

His dark eyes glinted teasingly. "Come here."

Without hesitation, Juvia bolted out of Lyon's arms. Gray smirked as Lyon's jaw dropped.

Once in front of Gray, Juvia turned around, giving Lyon a short bow. "Juvia's sorry, Lyon-sama, but Juvia's heart belongs to Gray-sama."

The smirk fell from Gray's face as he looked at the girl standing before him. Her voice sounded so… sincere, surprisingly, and it stirred something unfamiliar in his chest.

Juvia twirled around with excited eyes and a bright smile. "Which position is it, Gray-sama?"

Gray studied her face before glancing towards Lyon. The older man was mouthing incoherent words, as if trying to grasp what had happened in the last few seconds. His reaction was the funniest thing Gray had seen all day, and though he really didn't want to answer Juvia's question, he couldn't help but take the golden opportunity to screw with his figurative brother.

So he leaned towards Juvia, raising a hand and gingerly brushing her hair over her shoulder. The girl forgot how to properly breathe as Gray smirked and brought his mouth to her ear.

Locking his eyes on Lyon, he whispered, "I'll show you."

Juvia promptly fainted, collapsing into Gray's chest while Lyon's face turned various shades of red and purple. Gray caught the girl and laughed—finally, something fun out of this day!

Tossing Juvia over his shoulder, Gray gave a teasing salute before taking off, leaving a fuming Lyon behind.


His first instinct was to head back to his apartment, only to realize what a grave mistake that would be. It was hard enough spurning Juvia's advances in public, and behind closed doors it'd be practically impossible, especially with a convenient bed in the adjacent room.

He placed her on the ring of a fountain, keeping her steady as he knelt in front of her. She stirred as her eyes opened, blinking dazedly.

"G… Gray-sama…?" she called groggily, seeing two blurred forms of Gray blend into one.

He studied her face, watching the light return to her eyes. "You good?"

She placed a hand on her forehead, swaying slightly. "What happened…?"

"You fainted," he told her, resting his hand on the small of her back to keep her from tipping into the fountain.

"Lyon-sama showed up… and then…" She gasped, instantly perking up as her eyes gleamed. "Gray-sama promised to show Juvia his favorite position!"

He flinched, a chill shooting down his spine as his good mood immediately dropped. Shit, he had forgotten all about that. He was too busy laughing at Lyon.

"Um, uh—"

He shook his head, ridding the blush from his cheeks as he stood up and shoved his hands in his pockets, walking away.

Juvia squealed and bounced eagerly to his side. "Are you going to show Juvia now?"

Gray ignored her, keeping his eyes fixed determinedly on sidewalk before him. Great, now what was he supposed to do? That damn potion brewer—he'd never have to be in this horribly awkward position if the stupid potion hadn't existed in the first place! If he ever found the bastard, he'd make him die a slow, painful death for making him put up with this lunacy.

Juvia laced her fingers through his and fondly nuzzled his shoulder. "Oh, Juvia can't wait…! She's thought about it for a long time…"

"Keep thinking about it," he said tersely, undoing their intertwined hands.

A pink blush spread across her cheeks as she sighed dreamily, gripping his arm. "First, Gray-sama pushes Juvia down on the bed…"

Oh hell no. "Juvia…" he growled dangerously low.

"Or wherever Gray-sama wants it, Juvia doesn't care." She smiled. "Then Gray-sama declares his love for Juvia—"

"—That's not happening—"

"—and kisses her really hard, like this."

Before he could react, her lips were on his with her hands in his hair. His protest was muffled as she tilted her head, brushing her tongue against his closed mouth. Her fingers massaged his scalp, sending delicious shivers down his spine. He steeled himself, refusing to let his eyes close because bad things would surely happen, but she used some unknown strength and pushed her tongue inside his mouth, clashing against his.

He cursed, shutting his eyes tight while her hands slid down his neck to rest on his shoulders. His mind was reeling, his heart pounding way too hard in his chest.

Damn it damn it damn it—

Finally she drew back, opening her eyes slowly. She sucked her lower lip, smiling alluringly.

Gray locked his gaze to anywhere but her face, refusing to watch the way her teeth dragged over her lower lip.

"Don't… do that," he breathed, desperately calming his raging hormones.

"Do what?" Juvia asked softly, tracing a finger along his collarbone.

A pleasurable jolt shot through his body, surprising him. Since when was his collarbone sensitive?

His eyes fell to her chest, pressed up so nicely against his. Stupid, stupid dress, giving him a sight he could barely resist.

He forced his ogling eyes away, snatching her wrist and pushing her back an arm's length. Muttering curses under his breath, he shoved his hands in his pockets and stomped away. This was getting to be too much, he thought, trying to hide his flustered face.

"Gray-sama!" the girl called. "Juvia hasn't told you the best part!"

She quickly caught up to him, to his dismay, and wound her arm through his again. "Hmm, let's see… after Gray-sama is done kissing Juvia, he rips off her clothes!"

An image came to mind, an image so vivid it made him choke. Shit, this was bad—really bad.

"Be quiet," he hissed.

"Then Gray-sama touches Juvia… everywhere."

His face grew unbearably hot. Someone help him.

"Gray-sama kisses her neck, and then…" Her blue eyes grew round and hazy as she took hold of his hand, massaging his palm. "Her chest…" To his horror, she leaned closer, pressing her round breasts against his arm as her cool breath washed over his throat. "Gray-sama… it feels so good…"

He swallowed down his rising lust. God damn it. Her voice shouldn't be turning him on this much.

"Your hands feel so rough… Juvia loves it…"

His fingers twitched, aching to touch. She continued drawing random patterns on his hand, enticing him. Her skin was probably soft and smooth.

"And your mouth… mm…"

He licked his lips, finding himself craving the taste of her on his tongue. His eyes fell to her soft neck, her voluptuous chest, then her ivory legs.

Fucking hell, he thought, snapping his gaze elsewhere. Why did she have to be so damn descriptive?

"That's enough—"

"Juvia thinks Gray-sama's a biter."

Damn it, she was right. He liked marking what was his.

"Every touch makes Juvia so… ahh… and when Gray-sama touches lower…"

She stopped walking, and so did he. She was crossing and uncrossing her legs, whimpering softly, while Gray was desperately shoving out the images clouding his mind.

He shut his eyes, but that just made the images all the more vivid.

Juvia, tangled in his bed sheets, looking at him with thick lashes low over her eyes. Marks on her neck and chest from his sucking and biting, her hair tousled and disheveled, her lips swollen from his rough kisses.

But his favorite part is her eyes, wild with raw desire.

"Gray-sama puts his hand between her legs…"

He touches her there, and her eyes glaze over. "Gray-sama… Gray-sama—"

And he loves it. Listening to her screams throughout the night. Watching her shatter in his arms again and again and—

"Fuck," he cursed, snapping his eyes open. His bare back pushed against concrete—where did his shirt go? Shit, he must have unconsciously stripped it off with everything getting so damn hot.

Juvia had pulled him to a narrow alleyway, looking at his face while her body pressed up against his. He could feel her heartbeat, racing as erratically as his while his chest heaved against hers in ragged breaths.

"It'll be so rough…" Her voice was a soft, sensual purr. "But Juvia will love every second of it."

Her eyes stared into his with that look, smoldering with raw desire.

His mind wavered between fantasy and reality.

Gray swallowed, breathing heavily through his nose. "Juvia," he said, wincing at how gruff his voice sounded. "You don't know what you're saying."

Her lashes fluttered as she tilted her head. "Juvia thinks Gray-sama likes it."

"I don't," he choked. She smiled and he glared. "I. Don't."

"Liar," she murmured, her lips brushing against his jaw. He tensed, shuddering as she ran a teasing finger down his bare chest. "Hasn't Gray-sama ever thought about it?"

Yes.

"No."

Damn that was pitiful—even he could hear how pathetic he sounded.

Juvia merely smiled. "Juvia thinks about it a lot. All about Gray-sama…"

His body went numb, unable to register anything else but her voice and her touch.

"Your mouth…" Her lips brushed against his. "Your hands…" Her fingers toyed with his. "And your…" Her hand reached down and rubbed him, agonizingly slow.

He groaned deliciously low, closing his eyes and tilting his head back. God, who was this girl?

"You're… not Juvia…" he rasped.

"She is," she whispered. "Juvia is Juvia. Gray-sama is—" Her fingers squeezed and she gasped. "…huge."

All blood rushed south.

"Fuck," he cursed, pushing her hand away.

"Gray-sama…" she moaned. Just like his fantasy. "Gray-sama—"

She pressed her lips against his, wrapping her arms around his neck. He tried resisting, but all he did was grip the back of her dress. His fingers brushed against the zipper, so easy to pull down…

She kissed him deeper, pushing her tongue in his mouth. He squeezed his eyes shut as she sucked his lip before rubbing her tongue against his. God, since when was she such a good kisser?

His head was spinning with wild, crazy hormones screaming kiss her kiss her kiss her while she sucked his tongue.

He grunted, gripping her forearms and prying her off him. But in the narrow alleyway he couldn't push her very far, leaving her still pressed up against him.

"Don't come closer," he ground out through clenched teeth, ignoring her warm breaths fanning his neck. "Just… stop."

She stared at his lips with half-lidded eyes. "Juvia doesn't want to," she murmured, grabbing the back of his head and kissing him again.

Gray groaned against her, trying to calm his pounding heart, but her tongue was in his mouth again and her soft curves rubbed against his bare chest andand—fuck.

He shoved off the concrete and grabbed her waist, pushing her back against the opposite wall. She gave a throaty moan and parted her lips as his tongue thrust inside.

His hand ran along the underside of her thigh before hitching her leg around his hip. Juvia gasped as he ground against her, shoving his arousal between her legs. Her fingers clutched his hair as she whimpered, her eyes shutting tight.

He kissed her greedily, crushing her lips to his. His hand buried in her soft wavy hair, angling her against him as she made little noises. Gray broke the kiss and tugged on her hair, tilting her head back. He pressed hungry kisses to her neck as she breathed, arching her back against him.

"Ah, Gray-sama…" she moaned as his tongue ran up her throat. "Touch Juvia… please…"

His hair brushed against her skin as he kissed lower, sending delicious shivers up her spine. She writhed against him, drawing him closer with her leg around his waist. He massaged her soft thigh, his thumb rubbing circles into her skin as his mouth kissed the valley between her breasts.

His restraint was slipping fast as he ground rough and fast into her. He squeezed her ass and her hips bucked against him, feeding his desire as her panties rubbed directly against his arousal. She tilted her head back and fisted his hair, moaning breathlessly as his tongue ran up her cleavage. He pressed a kiss before sinking his teeth into the swell of her breast, making her cry out.

"Ah…!"

Her little gasp made his eyes shoot open, snapping him out of his daze. Shaking, he stepped back and she fell to the floor, landing on unsteady legs as her hands gripped his shoulders.

She looked at him with confused eyes. "Gray-sa—"

Before she could finish, he looked away, rushing out of the alleyway.
