I haven't written smut in a while, so I understand if this is pretty bad. Just trying to knock the dust off.

"Dammit, Lucy! What were you thinking?!" Natsu shouted as the two entered the blonde's apartment. She groaned.

"If all you're going to do is yell at me, why did you follow me home?" she asked as she toed out of her shoes, sighing with the relief she felt.

"Because we need to talk about that crazy stunt you pulled today! You could have gotten yourself killed!"

"Oh, stop being so dramatic, Natsu," Lucy said, rolling her eyes. "Besides, you're always doing crazy things."

"Yeah, that's because I know how to keep myself alive!" he yelled, glaring at the back of her head with his fists clenched at his sides. He saw Lucy stiffen.

"Excuse me?" She slowly turned to face him, eyes narrowed. "Are you saying you don't think I know how to take care of myself?"

"Oh, come on, you know that's not what I meant!"

"Yeah? Well it sure as hell sounded like it!" Lucy shouted.

"All I meant was that I've been doing this longer than you have. I have more experience and know how to get out of certain situations. Besides, our powers are completely different! You summon spirits to fight, while I fight with my own fire."

"And that makes me weaker than you? I'll have you know that I have saved your sorry ass many times, with or without my spirits!"

"It hasn't happened as often as you seem to think it did! Besides, you ran out of magic power today, so clearly you couldn't handle things on your own!" Natsu's words seemed to just act as gasoline poured onto an already raging fire.

"Screw you!" Lucy yelled. "It's not my fault I had to try to summon two spirits at once! Had you not gotten on top of that mutant crab-thing, you wouldn't have gotten motion sickness! So not only did I have to find a way to get you off of it, I also had to keep myself from being attacked as well! You're welcome, by the way!" Lucy seethed. The job seemed simple enough, but when they had arrived, they found that the 'crab problem' that was explained in the listing was not a bunch of crabs in a city, but a gigantic mutant crab that seemed to have taken over the town as its own. They had been doing well enough, until Natsu tried to attack it from above. However, a leg of the crab had swung up and knocked him out of the air, the dragon slayer landing on the top of its shell. It wasn't long before he turned pale in the face and curled into a fetal position in hopes of calming his stomach. And so, with Loke already fighting by her side, she had to summon another spirit to help Natsu. She had been practicing well with summoning more than one spirit, but after such a vigorous fight, she was already left low on magic power.

"It's not like I tried that! I was just fine where I was!"

"You most certainly were not!" The two continued to yell at one another, having never had such an argument before in all the years they were partners.

"What did you expect your whip to do after your spirits had to go back to the celestial world for healing and you were drained of power?"

"It was all I had left!"

"You could have gotten out of there! I could have handled him on my own!"

"That's not how we work, Natsu, and you know it! We fight together until the end, no matter what!"

"Not when your life's on the line! That crab almost killed you!" With only her whip that Virgo had given her to fight with, Lucy was not left with much other choice. Yes, she could have fled to a safer area, but she was too determined to fight. She latched the whip around one of the crab's large legs, and when it raised it's claw, she was pulled up along with it. While in the air, she had found the strength to pull with all her might, managing to rip off the leg of the crab. However, in her moment of victory, it's other claw found her and grabbed hold of her, squeezing her body tightly and slamming her into the ground. Natsu, having been preoccupied elsewhere, saw this and his blood boiled white-hot and he found himself unable to control himself as he unleashed everything he had left onto that crab, getting it to release Lucy and ending it once and for all. Luckily, the injuries she endured were healed quickly once they returned to the guild hall.

"But it didn't, so just get over it! My life has been in more danger than that, so what's the big deal?" Lucy hissed.

"The 'big deal' is that I was the only other one there! Not even Happy was there to fly one of us out of there if we needed it! What if I hadn't gotten there in time, Lucy? What if-"

"Shut up about the 'what if's, Natsu! It didn't happen! Get over it!" The two were in each other's faces, both red and furious looking.

"It could have happened, Lucy, so stop taking the whole fucking thing so lightly! You weren't able to take care of yourself this time, and I don't want you to go do something stupid like that again!" Natsu yelled. Lucy's left eye twitched once with fury.

"Fuck you!" she screamed. He grit his teeth.

"Fuck me? Fuck you! I'm the one who-"

"Just shut up already!"

"I'll shut you up," Natsu growled. Before Lucy had the chance to respond, Natsu wrapped his hand around the back of her neck and closed the short distance between them, crashing his lips into her own. She squeaked in surprise at first, frozen in her spot, before she finally gave in and gripped at his opened vest with one hand and dug the other into his hair and tugged, matching the roughness of his kiss as she felt a sharpened tooth dig into her lip. She gasped and he quickly slid his tongue against hers, leaning in as close as he could, resulting in the two stumbling backwards into her room until the back of her legs came in contact with the edge of her bed.

Their hands were roaming quickly, trying to feel every part of the other, as if they would disappear from each other's arms. Natsu's hand found the front of Lucy's blouse, where it was torn enough to expose much of her cleavage. Her head fell back at his touch, breaking their kiss, but Natsu didn't falter, immediately moving his lips to her neck, his teeth dragging along her sensitive skin. Lucy thrust her chest into his hand and tightened her grip on his hair to bring him closer, needing so much more. His other hand moved from his bruising grip on her waist to her ass, cupping it and using it to bring her lower body closer, grinding his evident erection against her core. Her knees buckled at the sensation and she fell back onto her bed, dragging Natsu with her, who immediately straddled her hips and dragged his lips down her neck and to her chest, his hands gripping the torn parts of her blouse and tearing it apart further, taking her bra along with it. The action elicited a gasping moan from the blonde and she arched her back, pressing his face into her breasts, where he dragged his tongue down her cleavage and trailed it to one of her pert nipples, sucking it into his mouth.

He felt her legs jerk beneath him, making him groan as she rubbed against his straining cock. He looked up and met her eyes, the lust blazing in his reflecting in her own. Lucy cursed at the erotic sight, then even louder when he bit down, grinning devilishly at how she writhed beneath him. She released his hair to push his vest off his shoulders, her nails raking up his back as he turned his attention to her other nipple to give it the same treatment as the first. Natsu lifted a leg, pressing it between her own to have her spread them, but instead, she wrapped her legs around his thigh and ground against him, almost without control.

"Fuck, Lucy," he growled, his breath hot on her moist nipple. He looked down the length of their bodies, watching as her hips rolled forward and back against him so wantonly. Lucy fisted her hand in Natsu's scarf and pulled his attention back to her face, leaning in close. She smiled sweet, but it looked almost threatening, slowing her hips but pressing her core harder against his leg.

"Natsu, if you don't get your pants off right now and fuck me, I'm going to throw you out this window," she said, and the look in her eyes let him know she wasn't messing around. Not that he was hesitating, anyway. He only grinned that devilish grin, his sharp canines shining in the light coming in from the window. He didn't miss a beat, tearing away her skirt with a quick rip. Lucy surprised herself by the fact that she wasn't angry about him ruining her clothes, instead finding that his actions fueled the burning desire shooting down to her core.

She almost wished she had worn more clothes just so he could tear them off.

In her moment of thought, Natsu had, at some point, discarded the rest of his clothing, including his scarf. He settled between her legs, grabbing her wrists and pinning them above her head as he leaned in to bite and suck at her neck again while he ground his cock against her wetness, the both of them letting out throaty moans.

"Now, Natsu," Lucy hissed, rolling her hips against him in attempt to just get more. "Don't be gentle, either."

Natsu snapped his eyes up to hers, his pupils dilating. Something about the argument between the two of them, the heat and passion behind the words they yelled at one another, made this all happen, and it fueled the raging flames within them. He growled deep in his throat, crushing his lips to hers once again and releasing her hands to place them on either side of her head. Lucy reached between them and gripped him, stroking him a few times for herself, smirking at the reaction she got from the dragon slayer before, finally, lining him up and reaching around to grab his ass, forcing him into her in one deep thrust.

"Oh, fuck!" Natsu shouted, and Lucy cried out, arching up against him and digging her nails into his ass, keeping her pressed deep inside of her. She then raked her nails up his back, wrapping her legs around him.

"Natsu, move," Lucy hissed into his ear, biting at his earlobe. He hissed and pulled back before slamming back in, the both of them gasping loudly. It wasn't long before Natsu set a pounding, unforgiving rhythm, and Lucy was loving every second of it.

"Shit, Luce…" Natsu growled against her neck, biting down at a spot that had her digging her nails further into his back. He wouldn't be surprised if she drew blood. Lucy's apartment was filled with gasps, moans, and cries accompanied by the sound of slick skin-against-skin, Natsu's thrusts growing erratic as Lucy bucked her hips, the combination having them fall out of rhythm, but everything still felt oh-so-wonderful. Natsu slid one hand down the length of Lucy's body until he found that small bundle of nerves right above where they were connected and rubbed at it to match his own pace. Lucy all but screamed, her legs tightening around him. She seemed to lose any bit of control she had left, reaching out with one hand to grab anything she could and finding her hand digging into one of the pillows by her head. Her eyes rolled back as she gasped desperately, chest heaving, and finally, the built-up pressure deep in her gut released and she screamed out again, accidentally yanking the pillow over her face and gripping it tightly now with both hands.

Natsu wasn't far behind - certainly not with the way she was squeezing him like that. He got in a few more thrusts before he couldn't hold back any longer and came with a loud groan, jaw clenching tightly and eyes clamping shut. When he was spent, he turned and fell onto the bed next to her, staring wide eyed up at the ceiling. After coming down from her own high, Lucy lowered the pillow over her chest to stare straight above her as well, chest heaving.

Neither spoke, the apartment now deathly silent, save for their heavy breathing. They weren't sure how long they stayed like that, but at this point, the sun had begun sinking below the horizon, casting an orange-ish hue into Lucy's room.

"So," Lucy began somewhat breathlessly, "that's what it's like to play with fire."
