A/N: Damn, the prompt is too long to make it the chapter title.
"Who the hell said you could flirt with what's mine!?"
"What's a beautiful woman like you doing here?" Lucy heard a sleazy voice ask her as he sidled into the bench she was sitting on.
"Just waiting for someone," she replied simply as she continued reading her book. Natsu was on a job right now, and Lucy'd convinced him to come home by train and get to Magnolia faster. He'd told her he'd only do it if she was there at the station for him when he got off, and so here she was, awaiting the arrival of Natsu's train, supposedly coming in just a few minutes.
"Hm, boyfriend?" The man asked, persistent.
"Well, no…" Lucy admitted. "He's just a friend."
Which was true. They'd been dancing around each other for so long. And though they both were vaguely aware that they shared mutual feelings, neither had taken that first step yet.
The man grinned excitedly at her answer. "Oh, so you can meet me for dinner tonight!"
Lucy put her book down, knowing she wasn't getting anything out of it currently. "I don't know…"
"No dinner? Perhaps coffee might be better?"
Lucy winced a bit, and the man finally sighed in resolve. "Alright then, thought I'd try. Could I leave a phone number though? In case this 'friend' of yours never does anything?"
Natsu groaned as the train finally rolled to a stop and the doors opened. The thought that Lucy was waiting for him just beyond them was the only thing that got Natsu up with Happy's beckons. He shuffled out of the car, Happy tugging on his vest and bearing most of the weight of their luggage.
He looked around for Lucy, hearing and smelling her before seeing her.
And the man currently talking to Lucy was enough to shoo away the last effects of motion sickness, a newfound energy swarming through his system.
Lucy didn't get the chance to answer the man's request as Natsu stormed over with a shout. "Who the hell said you could flirt with what's mine!?" Natsu shouted, pulling Lucy behind him possessively, trying to make himself look big, although the man across from him was a bit taller than Natsu was. That didn't stop Natsu from keeping a tight grip on Lucy and staring the man down with a fierce glare and one lit fist.
Happy floated nearby, not knowing what to do. Lucy just gaped with wide eyes at Natsu. The man looked bewildered for a second, staring between the fire, Happy, and Natsu's pink hair. And then he burst out laughing.
"I thought I recognized the beauty. Lucy of Fairy Tail and close partner of the Salamander and the flying cat." He chuckled sheepishly, rubbing the back of his neck. "Well, sorry for bothering you. I'll be leaving."
"Yeah, you better be!" Natsu growled after him.
"Natsu?" Lucy questioned, not knowing where to start. "You… didn't have to get so extreme. He was a little persistent, but he was being nice."
Natsu's frown deepened. "I don't like people thinking they can have what's mine," he growled under his breath as he grabbed her shoulders in a tight hold and stared deep into her eyes.
"Natsu?" Lucy unconsciously stepped closer to him and leaned the slightest bit towards his lips.
"I shoulda done this a long-ass time ago," he whispered before pulling her against him and meeting her lips with a fierce, fiery kiss.
Lucy couldn't help the whimper that escaped her lips. Was this really happening? After so long, they were actually kissing?
Her hands went into his hair and gripped the soft locks, almost as a way to ground herself and confirm that this was, in fact, real. Natsu let out a soft growl at the feeling, opening his mouth ever so slightly and letting Lucy flick her tongue against his experimentally, which quickly ended up with them deepening the kiss. Lucy felt light-headed as she was bent backwards from the ferocity of Natsu's lips.
Happy coughed, amused, the sound enough to break through Natsu and Lucy's haze, the two slowly breaking apart as they chuckled sheepishly.
"You liiiiikkkkeeee each other," the exceed teased. "But get a room!"
And the three were finally leaving the train station, Natsu and Lucy holding hands and sharing dopey smiles.
"So I can really call you mine now?" Natsu asked, voice husky after their kiss.
Lucy wore a sultry look before giving him a quick, but intense peck. "Only if I can call you mine."
Natsu's expression quickly darkened to match hers. "Hell yeah."
