So, technically chapter 3, but was basically just me practicing smut.

It does give some insight into their relationship, especially the last paragraph, but it's not necessary to read if you're avoiding mature content.

So, standard: WARNING: NSFW - mature sexual content

(fuck, writing smut it difficult! like, you either have stupid euphemisms or unsexy real words. I don't know if I can do this again… I like to read it, but I feel ridiculous writing it - so awkward - I ended up sort of chickening out at the really good parts - i'm so sorry)

The Third Week

Natsu was beaming and his eyes were shining, but his breathing was ragged as he slowly lifted Lucy's tight top over her head. He just wanted to soak in the sight of her but he knew if he waited too long she'd get embarrassed. Not that she had anything to be embarrassed about. He couldn't get over how gorgeous she was. And she positively glowed. She always glowed, it was like she was filled with sunlight which was set free when she smiled. Jesus, he was getting sappy.

He was sitting on the couch, hips straddled by this girl he couldn't get enough of. Natsu leaned forward to nibble and suck the skin along her collarbone, using his unusually long, pointed canines to draw out a moan.

He smirked through his ministrations, thoughts spinning. It had been about three weeks since their first date had gone unexpectedly well. They'd ended up seeing each other every couple of nights; one of them deciding they wanted company and texting the other. Not all of them ended up like this. Sometimes they really did just hang out, going out to dinner or watching movies on the couch or just wandering to the park to watch the stars. He didn't mind. He just liked her company. Lucy usually had this calming effect on him and he found himself wrapped around her little finger. Not that she realised, which made it even better.

Lucy had clearly gotten impatient while he was lost in his reminiscing, as her hands made their way to the hem of his own shirt, impatiently tugging it off. Natsu's last real thought was that Lucy was the one really running this show. She seemed nervous and hesitant sometimes, but she had such a fire in her. He could be stupidly oblivious at times so she steered him. For all the confidence and boisterous energy he had, he was completely lost, drowning, dragged along for the ride; and he didn't have a single complaint. Lucy kissed him then, and he stopped thinking altogether.

Natsu returned Lucy's kisses with matched hunger as his slid up her bare thighs and under her short, pleated skirt. Her hands were gripping onto his back, her body trying to subconsciously pull her closer to his. His hands found the upper edge of her lacy underwear, but he quickly realised they were not in a position he could easily get them off. He had a brief wish that he could just set them on fire and turn them to ash before he instead placed his hands under her arse and stood, picking her up with him. He had planned to carry her to the bed, but apparently Lucy had other plans. She dropped her feet, slipping out of his hold and stepping back from him, breaking the kiss. With a very determined glint in her eye and a self-confident smirk, she removed the article of clothing that had just been annoying him. He smirked back and let her come back to him. She might have power over him, but this was a battlefield. Every time it turned into a bit of a power struggle. Both of them were stubborn and spirited, not liking to give ground often. He was not going to chase after her.

Unfortunately for him, today Lucy's game was to see how far she could push him before he snapped. She gracefully slid forward again, skirt swaying, still on her hips, and allowed her fingers to curl over Natsu's waistband. It unbuttoned with a quick flick and she slowly dragged the zipper down, while her lips trailed along his sculpted abdomen. His head tipped back as her mouth met his neck and he couldn't suppress a groan of pleasure. She let out a small gasp as his calloused hands suddenly squeezed her behind and quickly pushed him away from her, towards the couch. He was chuckling as he stepped backwards, but his baggy jeans had dropped to his ankles and he tripped over them with an undignified squawk. Lucy stopped in surprise before she burst out laughing. He looked so ridiculous awkwardly sprawled in an attempt to catch himself, half on the couch.

"Luuuuuucy!" He dragged out her name in a whine. "Don't laugh at me! I could have been hurt!"

She just snorted in response. "You? Hurt? When would that be new? You being injured is like your natural state of being."

He humphed and pouted at her. Lucy rolled her eyes.

"Don't pout. You're a lot less hot when you look like a 5 year old. You're still adorable, but it makes this being mostly naked thing weird."

"You're weird." But in a flash, his face had morphed into a smirk, eyeing her dangerously.

That's what she wanted to see. She sauntered over to him, unclasping and dropping her bra on the way. She leant over him and kissed him again.

She loved to kiss him. It was like fire and electricity. He tasted sort of smoky, but not in the cigarette kind of way, more in the campfire sort of way. It warmed her; melting her, sending her heart wild and making her groin ache.

Natsu's hands reached up to squeeze her breasts only to find they were brushed away. He made a small noise of protest which changed to another groan of bliss as Lucy's fingers trailed along the waistband of his boxers. His erection had been straining desperately for freedom since quite early on and he was starting to feel impatient as his desire started to spiral out of his control. He sucked in a sharp breath as he felt her dainty fingers slip into his underwear and he moved his hands to pull them off for her. He didn't exactly want her to move from where she was. He grinned into Lucy's mouth as she grunted and pinned him back against the couch. Natsu really liked this couch. It had served well and been a great wingman. Natsu squirmed. He wanted to touch Lucy, but she was determined to not let him. And he was getting frustrated with this game. Somewhere in the back of his mind, a voice suggested that she was trying to test his patience and if he could keep control she would eventually lost her patience. However, that voice was so quickly drowned out in the face of his need for her. He shuddered as her fingers and lips danced over his entire, naked body, driving him to the edge of his sanity. And over it.

Letting loose an animalistic growl, Natsu flipped Lucy, putting her under him, lengthways along the couch. She laughed as he used one hand to pin both her arms above her head and brace himself. She'd won. She'd driven him out of control and was going to get exactly what she wanted from it. His mouth claimed as much of her as it could reach while his other free hand slid down her body to her soft folds. He rubbed at her engorged centre causing her to moan loudly. Normally he would take his time to drive her into utter chaos, but she'd done all the foreplay today and knew full well that he couldn't concentrate long enough for that. She didn't need it; she was already begging him.

"Natsu… please…"

He pulled back slightly as he shifted his position, letting go of her arms and making sure his weight was supported. Lucy looked up at him, into his eyes. Their dark pools held a wild and dangerous gleam, but they were also overflowing with affection and care. She reached her a hand up to grasp at his pink hair. He growled again, low and deep in his chest, as her other hand moved to guide him into her. She continued to watch with amusement as he tried to fight for control over his body. She wasn't about to let him have it. He whimpered. With a bit of a wiggle and then a thrust of her hips, she sheathed him to his hilt. His control broke fully and he snapped his own hips against her.

"God, yes." Lucy muttered, quickly losing her own connection to reality. "Natsu, please, move."

So he did. Slowly at first, but gaining speed, he moved back and forth on top of her. Her legs snaked around his thighs, forcing him deeper with each thrust. She tangled her fingers of one hand in his soft, messy hair and sunk her teeth into his shoulder, while the other hand clawed at his back. She lost herself as he ravaged her, mind clearly as clouded as her own.

It wasn't long before she was gasping for air. She could faintly hear herself screaming as ecstasy overwhelmed her and she came with a crash and a shudder, arching backwards. Natsu wasn't far behind, breath catching as he suddenly stopped, stiffening, and then went slack.

Natsu dropped his head forward, resting it on Lucy's soft shoulder as he tried to catch his breath. His head had cleared as soon as he'd felt release. This woman was his blessing and his curse. No one else had ever been able to do what she did to his mind. He scowled slightly. Lucy had accidentally discovered his slight mental instability last week. It wasn't something he liked anyone to know about. Yet, instead of being scared, she'd just hugged him, saying that she knew that no matter what, he would never hurt her. God, he hoped that were true. He wanted to believe it. Then, she'd decided to use it. He didn't feel angry at her; he'd honestly never had it set off in this way (it was normally him getting angry and then into a fight), she hadn't been hurt yet, and he sort of liked that it could be 'used for good' as Lucy had put it. He raised his head to gaze at her face, checking she was alright. She just smiled sleepily back at him. He relaxed and gave her a lazy grin back. He nuzzled into her neck again, enjoying the comforting feel. He grunted slightly as she squeezed her inner muscles around him again, shooting shivers up his spine. Even if she found humour in the reaction, he was spent. She wasn't going to get another round out of him for a while. With a sigh she unwound her legs from behind him, allowing him to gently slide out. He flopped onto his side between her and the back of the couch, gathering her into his arms so she could snuggle into his chest.

"You 'right, Lucy?" He wanted to check anyway.

"Better than alright. That was amazing." She sounded tired which made him chuckle. For all the things that she could do to him, he was glad he could at least do this to her.

"Hey, Natsu?"

"Mm?"

"Are you?"

"Eh? Yeah, 'course."

"Hey Natsu?"

"Mm?"

"What is this? What are we?"

What kind of a question was that? It was dangerous. On the other hand, it was probably best answered with the truth.

"I have no idea."

"Hm. Me either. But I like it. I hope it continues." Her voice had turned into a mumble. She was falling asleep.

Natsu chucked again, softer this time.

"I hope so too, Lucy. I really like you." There was no rush to figure out their relationship status. They both knew it wasn't a fling and that was enough for the time being.

He planted a gentle kiss on her forehead before joining her in sleep, tangled together on his newly favourite couch.
