I got my inspiration for this from the Chapter 521 cover from the FT manga. The link doesn't seem to be working here and you can look it up if you want to. Basically, Lucy and Gray are sitting together at a café/restaurant place and Happy is looking up at both of them.
Lucy sighed as crumpled up another piece of paper and tossed it into the bin next to her and Natsu's bed. Another scrapped idea.
Truth be told, writing a novel was no easy feat. She had the dedication, but as with any writer, it was easy for her well of ideas to run dry.
She got out of her chair, stretching her legs to take a short break. It was strange at first getting used to living in Natsu and Happy's house, but things had started to settle down since the big move a few months ago. It was hard giving up her old place, as leaving it would be leaving behind all the memories she made in there. But then she remembered: no more rent, no more crazy landlady, and no more daily intruders (except now she was living with them).
Lucy had told Natsu she couldn't go on a mission with him today. She couldn't help but smile at his overjoyed expression when he shoved a flier to fight some bandits in Onibus, but the blonde was intent on hunkering down and making some good progress on her novel.
And yet, the day had been wasted. All she'd really done was click her pen. Lucy remembered Natsu's pouting and scowling before finally going off by himself to do the job. Happy had decided to opt out as well; something about delivering fish to Carla.
Well, maybe the day wasn't totally wasted... after all, there was that excursion with Gray.
She enjoyed the ice mage's company. Since they spent so much time together on missions and he was one of the first people she truly got to know at the guild, Lucy definitely felt a sense of closeness to him. She was a little surprised when he'd asked her to go out for lunch at a local restaurant but accepted wholeheartedly, with Happy tagging along as well for a short while. It was nice to catch up with him, since Natsu never wanted her out of his sight and Gray had his own respective person who took up all his time (a certain water mage, of course).
Lucy knew that there was no one else for her but Natsu, and her and Natsu's Edolas counterparts' relationship was enough to reinforce that thought into her head. The guild was her family, Natsu was her special someone, and Gray and Erza were like siblings. They bickered (mostly Natsu, Gray, and Erza of course) but always looked out for each other at the end of the day.
That was why she thought nothing of that interaction earlier in the day, and was even more confused as the door opened to reveal a clearly pissed of Natsu.
"We need to talk." Natsu grunted. Lucy looked at her boyfriend with confusion. His features were shadowed, but his eyes were very much alive. They resembled two embers, flaring with passion and... anger?
"Oh... hey, Natsu. How was the job? I promise I'll come with you the next time around." Dealing with Natsu's attachment issues was more than exhausting at times, but she couldn't deny that she found it endearing.
"It was fine. Got the full reward and everything. But that ain't what I'm worried about."
Before Lucy even knew how to react, Natsu stormed over to her and backed her up against the wall. "I heard things about you goin' on a date with... with him."
Lucy looked up at Natsu's infuriated expression. He wasn't that much taller than her, but just enough so that he felt imposing. Heat emanated from his body, and she began to perspire from both the temperature and fear of the current situation.
"What are you talking about? If you mean Gray, then yeah. He took me and Happy out to this new place for lunch. It was actually really nice; how about we go there sometime? Just the two of us." Lucy attempted to maintain a level tone but she was failing miserably. Judging from Natsu's continued leer and the raise of his eyebrow, he didn't seem too reassured.
"He took you out. That fucking popsicle took you out? And you went along with it?" Natsu's right forearm rested on the wall right above Lucy's head, and a strong hand from the other was gripping tightly to the top she had put on that morning. His face was getting closer and closer to hers, the tips of his fangs visible as he scowled down at her trembling figure.
"No, I didn't mean it like that! He just asked if I wanted to catch up with him. Nowadays, it's usually just us and Happy when we go on jobs. I kind of miss the days when we did work as a bigger team more often, you know?"
"Don't care. You hung out with another guy behind my back and I didn't even say ya could. I'm not just gonna let that slide." Natsu growled as his nose was pressed up against the blonde's, the seams of her top beginning to strain under his tight hold.
At this point, Lucy was over it. Over calming him down all the time, reassuring him that she would always be faithful. This was just ridiculous.
"I'm allowed to spend time with people that aren't you, okay? All we did was talk for a bit and then we went our separate ways. We're all guildmates, you dumbass! Besides, even if I did like him I would get instantly mauled by a rabid Juvia. And I don't need your permission to do anything." Lucy huffed out in defiance.
Natsu snorted in response. "So now yer calling me names? I already told you, I'm not gonna let anyone else have you. Especially not that ice freak."
"But I just said that—"
"Shut it. I'm gonna remind you that there ain't no one else for you but me."
At this point, Lucy began to struggle. She tried to get out of Natsu's hold, but his arms tensed and she was instantly immobilized. There was no way she could outmatch him in brute strength.
Natsu's lips suddenly plunged into hers. It was wet, sloppy, a release of pent up emotions and frustration. He nipped at Lucy's lower lips, gaining full entrance into her mouth. Lucy reciprocated his actions. His passion. She would prove to him that she didn't want anyone else.
Their tongues slithered in an intense back-and-forth. It wasn't pretty, but it sure felt right to the both of them. Natsu began to shrug off his vest as his lips remained firmly pressed to his girlfriend's, revealing broad shoulders and a sculpted physique. His tan skin was rough and scarred, the toll of countless reckless battles.
After a few minutes, Lucy pushed away from his greedy mouth to slip off her own top over her head. She didn't know exactly where this would go, but was ready to follow Natsu's lead.
His large hands rested on her slim shoulders before shoving her down onto her knees. Their house was filled with a tense yet fast-paced energy as Natsu began pulling down his loose white pants and took off his sandals. Lucy removed her shorts in turn and knew what was coming next, getting ready to show Natsu how badly she wanted him.
Natsu finally shed his boxers, which had been considerably tented just a moment ago. He unleashed his girthy cock, the tip brushing against Lucy's nose. It was huge to say the least, with a long vein running down its right side. Although they'd had many passionate nights in the last few months, Lucy had still not completely adjusted to the sheer size of his throbbing member.
"Suck." It was a simple command that carried all of his fiery heat. Unsure of how to approach it, Lucy gingerly swirled her tongue around the slit and head, coating it with her saliva. She began to venture forward, tenderly sucking on his cock; in contrast to the rest of his body, the skin there was soft and smooth, encouraging the blond to hollow her cheeks and keep going.
"Eyes on me." Natsu's expression was dark and filled with lust for the woman on his knees before him. Lucy tried her best to maintain eye contact, but it was incredibly difficult when she was forced to look straight into piercing onyx eyes.
She fucked her throat on his cock, engulfing it in saliva and creating a suction with her lips. The sound of light moans trickled out of Natsu's mouth, letting her know she was doing a great job.
The fire dragon slayer began thrusting into her mouth, entering the entrance of her throat. His balls tapped Lucy's chin with each rough thrust. Tears welled in Lucy's eyes, which were still trained on her partner. Natsu had a hand roughly grasped in her hair, pulling her head towards his body as he thrusted.
It was getting to be too much. Lucy was no match for Natsu's insatiable hunger. She tapped him on the leg, frantically trying to get him to stop.
Reluctantly, Natsu pulled out of her swollen red lips. Spit dripped out of the corners of her mouth, and she coughed and gagged repeatedly as he maintained his harsh grip on her hair.
"Just couldn't handle it, huh? That's too bad. 'Cause now..." He leaned down, his lips pressing against her ear. "I gotta punish you."
Natsu picked her up princess style like she weighed nothing and tossed her roughly onto their bed. He singed off her violet lace panties before his hard muscles collapsed over her soft form.
All Lucy felt was frustration. She tried getting the upper hand but had failed miserably. Natsu's raw intensity overpowered her will, and she'd given up and given in. But still...
It kind of felt good for someone take control.
The fire dragon slayer's toned arms flexed as he pinned both her wrists above her head with one of his hands. The rough pad of this thumb began circling her clit, eliciting long moans from the beautiful woman below him. His head was normally a jumble of thoughts, but all he could think in this moment was "Claim her. Make her yours".
He lined the mushroom head of his long cock with her leaking pussy. He eased his way in, her lower lips spreading as he plunged deeper.
"Oh, Natsu..." Lucy was breathless, her words taken away as Natsu began to enter her. In contrast to his behavior before, it was soft, it was sweet, it was—
"Oh God Natsu, oh my God!" Lucy cried as the man above her suddenly plunged into her cunt and began a ravenous mission of exploration. Those two actions truly encapsulated who Natsu was. He could be so gentle, but definitely had a rough side to him.
Natsu leaned into her ear once again. "So soft and wet, aren't you Lucy? And all for me. Not for Gray, not for any other man. If I see another guy touch you, I'll burn 'em into a pile of ashes. You're gonna stay away from them from now on. All of them. Got it?"
He roughly lowered one of her pinned hands and held it down on her stomach, which was bulging with the intrusion of his cock. She could feel the movement of Natsu's thick member as it pounded in and out of her with her palm.
"Stop being ridiculous. Can't you see that I only want you!?" She shrieked it out all at once, as it was hard to concentrate with the waves of pleasure she was feeling. Her body shuddered and her toes curled as Natsu ravaged her mercilessly.
Natsu's eyes widened in shock, losing their fiery glint. His thrusts slowed as he processed her words. "You- really? You promise?" Lucy couldn't help but chuckle at how badly he needed her word.
"Yeah, yeah, I promise. Now keep going, or no fire chicken for you tomorrow."
"What! You're so mean to me, Lushi... but what the lady wants, she gets." Natsu grinned deviously as he continued his conquest on her pussy. She really was all his. The one he'd spend his eternity with. And that thought made him ridiculously happy.
After a long night of passion, Natsu finished inside of his partner. Lucy cooed from the sensation of his warm seed trickling down her perineum and onto the sheets below.
He pulled out sloppily and collapsed next to her on the bed, both of them too tired for a proper cleanup. He turned her to her side and put a strong forearm around her waist.
Natsu's mind had cleared after finally fulfilling his raging desire. Tentatively, he explained, "Hey, Lucy... I didn't mean to scare ya earlier. It was just a long mission, and I hadn't eaten, and I was overthinkin' it. You're right, I don't get to control ya and—"
"Shhh, it's okay." Lucy turned around and gave him a warm smile. At that, he replied with a toothy grin of his own. As long as Lucy was happy with him, everything would be okay.
But then, she suddenly turned around and pressed her body right on top of his. Natsu yelped as she held the sides of his head. He may have been done, but it seemed Lucy had a lot more left to give.
"You know, it's not like I like it when you make jokes with other girls at the guild. I don't like how you're so friendly with everyone. Too friendly. It may not be all that healthy, but... " She leaned down, preparing to place her lips on his once again.
"... just know that I can get pretty damn jealous too."
