Heated Kisses

Lucy opened the door to her apartment. She was mentally exhausted. Yet another one of her dates went awful. There wasn't exactly anything wrong with him like the others, he just didn't catch her interest. None of them seemed to be able to do that...

After a long soak in her bath she was feeling a little more refreshed, but she still couldn't shake the thought that she would never find the right guy. It didn't make sense to her. She'd been trying to date for the better part of six months now, and never had she made it past the first date.

She'd shared a few kisses with them, but that was it. It never made it past a rare goodnight kiss at the door, then she would never see them again. She didn't think it was fair to waste her time or theirs. She didn't want to say she was one of those people who believed that they should feel fireworks explode when they have their first kiss, but she couldn't deny that her bar was set pretty high. So far no guy had made her knees weak or made her see stars.

Lucy sighed, wondering if she was just not meant to be with someone. In nothing but a towel, she strolled over to her closet, her feet barely lifting from the floor as she walked. She pulled out a simple tank top and white mini skirt, knowing they would be comfy since the weather had started to warm up. She didn't think she'd be leaving her home again today anyway, so there was no point in worrying about her wardrobe.

Lucy was about to walk over to her desk to start writing, but a loud and cheery voice startled her.

"Hey Lucy!"

Said girl flinched, letting out an 'eep' as she whirled around to see the pink haired fire dragon slayer sitting on her living room floor. "Natsu! What the hell are you doing here?!"

Natsu raised a brow. "I came to hang out with you!" He said as if it were obvious, because to him, it was. He always loved spending time with her. "I didn't see you at the guild this morning."

"That's because I was out on a date," Lucy turned, not catching the way Natsu's eye twitched when she said 'date'. "Where's Happy? I swear if he's raiding my fridge again I'll-"

"Happy's not here," Natsu answered, his tone a little dejected.

Lucy easily picked up on his mood change. "What's wrong with you?" She asked, forgetting she was in nothing but a towel.

Natsu glanced up at her, his cheeks going pink before he looked back down at the playing cards in his hand. "Nothin'."

"Like I believe that." Lucy placed her hands on her hips, her clothing tucked under one of her arms. "Come on, spill it."

The dragon slayer grumbled something under his breath before saying, "you should probably get dressed... Your towel's slipping."

Sure enough, when Lucy looked down the towel was drifting further south. She quickly clutched it to her body, then stomped back to her bedroom, muttering that she wouldn't have to change in there if a certain intruder didn't barge into her place uninvited.

Natsu ignored her statements. If Lucy really didn't want him to come by she would lock her window. Instead it was always unlocked, sometimes even opened. He would respect her privacy if she had a more serious talk with him about it, but for now he would continue to pop into her place to hang out with her.

The celestial wizard came out a few minutes later. Her hair was brushed, now in two long pigtails. Her tank top was a little tight and her skirt was a little short, but she didn't mind. It's not like Natsu would check her out anyway. As far as she knew the boy didn't care about girls.

The girl sat down in front of Natsu, not saying a word as she scooped up the cards. He protested, but she ignored it in favor of setting up a game of poker. The boy smiled when he accepted his hand, settling into the game since it seemed to make Lucy's attitude shift for the better.

They chatted about a mission Natsu had seen on the board. It looked like something they'd be interested, but he didn't grab it because he didn't know if she'd be free or not. Lucy said if it was still there tomorrow morning then she'd accept it with him. Her rent was coming up soon anyway.

After a few rounds, he asked, "how was your date?" He didn't want to ask, but his morbid curiosity got the better of him. He noticed the way Lucy's eyes dulled, the corners of her lips pulling down.

"It was okay," she mumbled, looking at her pitiful hand.

"Just okay?" Natsu asked, trying to reign in his happiness. He felt awful, truly he did. He was her best friend, so hearing that her date was 'exciting' or 'good' should have made him upset, but it didn't. Natsu was good at keeping his feelings a secret, and the particular feelings he shared towards the celestial wizard could be described as love.

Natsu knew he loved her a little bit after she joined Fairy Tail, but he had kept quiet about his feelings. He knew the type of guy she was looking for, handsome, charming, and respectable. In other words, not him.

Natsu just didn't fit into that category. He was rough around the edges. Sure he had his own good looks, but charm? He didn't really have that. Maybe a boyish charm, but what girl wanted that when they could have a prince charming?

"Yeah," Lucy started, cutting through his self-doubt. "Just okay..."

Natsu felt the guilt tug at his heart. Here Lucy was clearly suffering, and what was he doing? Secretly smiling that she was still single. It was completely selfish of him, so he sighed. "Do you want a hug?"

Lucy blinked, looking up at the dragon slayer in surprise. It was true that Natsu's hugs always cheered her up, but usually it was her stealing them instead of getting offered them. "Y-yeah."

Natsu shifted the cards to the side, setting his hand on the ground. He scooted closer to her, wrapping his arms around the blonde woman. He loved being near her, loved hugging her, but there was just something about being this close that made it hard for him to concentrate. Her scent overpowered his better judgement. It made him want to hold her tight, vow to never let her go. He felt his possessive nature flare up, the need to hoard her away from the world and call her his.

Lucy hugged him back, loving the warmth that radiated off his body. Being a fire dragon slayer had its advantages. Lucy hummed, closing her eyes and letting herself get swept away. Natsu was her best friend, the guy who was always there for her when she needed him.

A thought sparked in her mind, and before she let it slip, or let her confidence waver, she spoke. "Hey..." Her voice came out as barely a whisper. "Can I see something...?"

Natsu pulled slightly away to see her face. He was about to ask what she wanted to see, but he had no time to respond. The next thing he knew was he felt warmth on his lips.

His eyes widened, shocked that Lucy was actually kissing him. Natsu was too stunned to move, unsure if this was really happening or not. His head spun, his heart started pounding while his brain tried to figure out what the hell was going on, and why his best friend was actually kissing him.

Lucy let her eyes flutter closed. She felt the heat from his lips as she applied more pressure. She didn't want to admit it, even to herself, but there was no use denying it. Lucy didn't feel fireworks, she felt explosions, and that was just from a simple kiss. It set her skin on fire and her heart into overdrive.

Lucy parted her lips, her tongue coming out to see exactly what Natsu's mouth tasted like. He was about to ask what she was doing, but he was rendered speechless when her tongue slipped into his mouth with ease. Her tongue roamed around, playing with his vapid tongue.

Natsu pulled way, out of breath and extremely confused. "Lucy..." He didn't mean for his voice to sound so breathless, but that's the effect she had on him. "What are you doing..." He felt her arms tighten around him, her body coming closer as she sealed her lips over his again, giving no answers for why she was kissing him. Her breasts pushed up against his bare chest in the process.

Lucy's hand cupped his cheek as she smoothed her thumb over his skin. Natsu felt heat creep over his face and neck. It was weird for him to actually feel hot. His body physically responded to her actions while his mind was shutting down from too much thinking. It was almost like natural instincts took over when he cupped the back of her neck, pulling her in closer.

Natsu didn't know why all this felt so good, but he wasn't about to start questioning it. He just didn't want it to end, especially when Lucy started rubbing her lower half against his crotch, stirring up a fire that raged in his belly unlike anything he'd ever felt before.

Lucy's lips pulled away from his, her eyes hooded and hazy. Natsu was still in a daze, his breaths coming out shallow as he looked at the celestial wizard now straddling his hips. 'When did she get like that?' She leaned in, planting her lips on his neck. Lucy had to push his scarf aside, then she left wet, open-mouthed kisses from his jawline down to the jagged scar adorning his tanned flesh.

Natsu let out a soft moan at the strange pleasure she caused him. She gave his neck one last lick before returning to those scorched lips. Natsu didn't hesitate to shove his tongue into her mouth, drawing out a whimper.

Lucy tried to fight back, but Natsu proved to be quite the foe. What was supposed to be another heated kiss quickly turned into a battle of the tongues to see who could dominate the kiss.

Lucy cupped both of his cheeks, the tips of her thumbs reaching the corners of his lips to try to distract him. Natsu decided he could play her game as well, bringing his thumbs up to her lips. Natsu furrowed his brows when she stuck the pad of her thumb into his mouth.

Natsu growled, his own thumbs mirroring her actions. Before either of them knew it they were ending the kiss in favor of trying to widen the other's mouth. Lucy's cheeks were stained light pink, a few tears coming to the corners of her eyes when Natsu spread her mouth wider.

Lucy did the same, jerking her thumbs further apart to really stretch his mouth. Neither seemed to want to give up. Lucy ignored that her skirt was hiked up while Natsu ignored how cute she looked growling back at him. He finally let go of one side of her mouth, only to grab at part of her shirt to tug at it.

"Give up," Natsu muttered, not wanting to pull her cheek any more.

"Naaatsuuu," she groaned, mouth moving to try to chew on his thumb. She managed to nick the edge pretty hard, forcing him to let her go.

They pulled apart, both massaging their cheeks to relieve the pain that had accumulated during their little battle. Lucy moved away from his lap, scooting further away from the dragon slayer. Natsu wanted to protest, but what could he really say?

"Hey Lucy, I want you to sit on my lap so we can make out again?"

Yeah... That didn't seem like the best approach. He still didn't even know why she kissed him, but he wasn't about to complain.

When Lucy didn't say anything for a long minute, Natsu decided to just summon all his courage and just put it out there. The corner of his lip twitched, fear trickling in as he spoke. "Hey Lucy..."

Lucy looked over at him, feeling embarrassed over what she just did. She kissed Natsu, out of seemingly nowhere! What could he possibly think of her? Was he mad? Not likely... He had kissed her back. What if he thought she was easy, if this is what she did with all the boys she went out with? She couldn't live with herself if he thought of her like that.

Hesitantly, she mumbled, "yeah?"

Natsu gulped, a lump stuck in his throat. He feared rejection. He feared messing up their friendship, but after that kiss... He feared never kissing those sweet lips again far worse. "Do you maybe... maybe wanna go on a date... with me?"

Lucy stared at him, seeing the color filling his cheeks and his eyes flitting left and right in a nervous manner. She could have waited a while, made him suffer, but she wanted to put him out of his misery.

With a soft smile, she leaned in. "I'd love to," she said, then gave him another heated kiss.

Let me know what you thought. :) Sorry if it's rushed, it's just supposed to be a quick one-shot. Is this okay for rated T? I know part of it kinda dances on the line between T/M.
