A NatsuxGray story – Body Heat

"Oi, Natsu! Gimme back my underpants!" Gray yelled at an infuriating pink haired man he called a member of his team. The man in question was called Natsu, who was currently spinning Gray's underpants around his finger with a smirk on his face like he'd accomplished something major.

"No way cold-toes, that'd totally defeat the purpose of taking them! Come get them!" Natsu countered and lit his free hands with his flames. "Before I burn them!"

"That's my favorite pair!" Gray launched himself at Nastu, if anything just for the sake of not letting the pink idiot win. Using his self-proclaimed superior mind skills, Gray managed to trick Natsu into letting go of his underpants with a feint punch to the face, and snagged his shorts back.

"Whataya think you're doing, flame brain?" Gray shouted, pulling his underpants back on. He wasn't in the mood to strut around completely naked, especially with Nastu around. For some reason having the dragon slayer see him naked made him antsy.

"What does it look like, dumbass? You're always stripping, so today I decided to finish the job for you," Natsu said, rolling his eyes like it was the simplest thing in the world.

"What'd you say, pointy eyes?"

"Ha! You've got a bad memory to go with your bad habit, droopy eyes!" That was it. Gray decided it was time to show the pink idiot who is boss. He got up in Natsu's face, provoking him.

"Sorry, my memory tells me you're stupid. Is it wrong?" And just like taking candy from a baby, he and Natsu engaged in a contest, hands locked, trying to get the other to step back. Both ignored the laughter their fighting usually elicited, this was a matter of concentration. To step back meant to loss to the other. But their concentration was blown by Fairy Tail's doors being thrown open by Nab, who had just left moments ago to 'go on a job'.

"Erza's back!" Nab said and a round of panic spread around the room. Everyone scattered to do something that looked benifical and productive the moment they could hear her footsteps. Everyone except Natsu and Gray, who were trying to get out of the headlock Nastu had put him in. Arms got tangled and they couldn't get out before Erza walked in with Lucy in tow.

Wanting to be free before things got hairy, Gray took his hand and shoved it under Natsu's chin, forcing the man's head back, and Gray took the opportunity to weasel free on Natsu's grasp. Natsu fell in his butt and Gray straightened up just in time to see Erza approaching, Lucy slinking off to sit at a table, looking like she'd sleep if you just said the word.

"I'm surprised to see that everything is in order. Well except for…" Erza launched a glare at Natsu and Gray, but after that, turned her attention back to addressing the whole of Fairy Tail.

"But moving on from them, I'm glad to see you are all well behaved today. Instead of the usual—" As Erza prattled on and on, and neither Gray nor Natsu paid any attention. They 'learned' to tone her out when she started talking about discipline.

Natsu discreetly punch Gray in the shoulder blade, to which Gray retaliated with an elbow to Natsu's rib cage. This started another small tussle that ended at a glance by Erza. The two quickly put one arm around the others shoulder and started singing a nonsensical song.

As soon as Erza looked away Gray and Natsu separated, glowering at each other. Gray could still feel Natsu's warmth against his side from where they had been side-by-side, but tried desperately to ignore it, waiting for the external heat to fade from his skin. He found himself dropping his gaze, surprising Natsu by backing down. For some reason, he couldn't bear to look into the dragon slayer's eyes anymore.

"Oi. What's up Gray? Constipated?" Natsu asked, concerned because Gray never backs down from a fight, even if it's just a stare down. Gray felt his heart beat faster, unable to comprehend why. There was something about having close proximity with Natsu that was messing with his head, and he couldn't think about why that was for that exact reason. After what seemed like ages of Erza talking, finally she stopped and that was his only safe chance to get away.

Gray waited all of two seconds "I'm gonna go on job" He rushed over and snatched a job request from the board, just as Nab was reaching for it. Walking as fast and yet a casually as he could out of Fairy Tail, he had gotten about 5 yards before an overly persistent dragon slayer caught up.

"What d'ya want Natsu, I'm going on a job," Gray said to Natsu as the pink haired man caught up, not stopping to slow his pace.

"We're a team aren't we?" Natsu said, smiling slightly and Gray shot him a look.

"If that's the case, then you should have brought Lucy and Erza with you." Gray retorted, hoping Natsu would get deterred and back off. Natsu coming with him would totally defeat the purpose.

"They just got back from another job, making them go on another would be like asking Happy not to eat fish for a day," Natsu said grinning, and Gray inwardly cursed him for using him brain for once. Even if it involved comparing Lucy and Erza to Happy.

"Speaking of Happy, where is he?" Gray hoped that, upon noticing Happy wasn't with him, Natsu would run back so he could make a break for it.

"Happy's teasing Lucy, he told me to go without him. I know, I was surprised too," Natsu replied and Gray slapped his forehead. He slowed to a halt, sighing.

"If you're so insistent on coming, I might as well tell you that I'm not actually going on a job, I'm going home."

"Then why'd you take the job request with you?"

"That was an excuse." Gray snapped and Natsu blinked at him, raising an eyebrow and looking confused.

"I don't get it." Natsu said.

"I didn't expect you would. Lemme spell it out for you, it was supposed to be to away from you. Now that you know, you can go back," Gray said a little harshly, but hopefully it would make Natsu back off and give him time to think. Instead, it just backfired.

"Oh? And what's that supposed to mean?" Natsu said getting in Gray's face, but instead of getting flustered from how close they were, this time Gray just got angry.

"It means that I don't know why my body keeps acting weirdly around you so I wanted time to figure out why and I can't think straight around you!" Gray yelled and regretted his short temper immediately. It sounded to him like a confession and Gray felt his face grow warm. Natsu looked a bit shocked but it was quickly replaced with a grin.

"Well, I'll just have to help you find out won't I?" Natsu pulled Gray along behind him despite Gray's protests.

"I just told you my brains messed up around you! I'll be able to think better on my own!" It suddenly occurred to Gray that Natsu was gripping his hand in his. Natsu's hand was so warm. For some reason, Gray's heart sped up and even though he didn't know where Natsu was dragging him, he shut-up and let Natsu hold his hand the whole way.

It wasn't long until they reached a really beat up looking house on the outskirts of Mangolia. Gray was confused right up until he saw a crocked sign that said this was property of Natsu Dragneel and Happy.

"Oi, Natsu, why'd you drag me to your house?" Gray asked as Natsu lead him inside. The inside didn't look much better than the outside as it was really dirty. Natsu had pictures of everyone in Fairy Tail, including Gray. He even had a manikin with a maid outfit labeled: first job with Lucy. Gray hastily shook his hand free of Natsu's and decided to distract himself with another question.

"Flame brain, how exactly do you intend to 'help' me figure out what my problem is?" Gray asked, wondering why Natsu was unearthing his bed from a pile of junk. After about twenty seconds of no reply, Gray felt his temper start to act up again.

"Oi, Natsu! Answer me!" It was at that time that Natsu turned to him, faintly blushing, but still grinning. And now Gray was just confused. What was up with Natsu? He never blushed, so why was he starting now? The dragon slayer said something incoherent that Gray didn't quite catch moments before he claimed Gray's first kiss, hands on the navy blunette's shoulders to keep him from escaping.

That's when he realized what Natsu has said was: "By letting your body decide" Gray shoved at Natsu as soon as he realized what the pink haired man had said, surprised and flustered. He protested as soon as their lips were far enough apart. That didn't go all that well. As soon as Gray's lips were parted, Natsu took the opportunity to shove his tongue inside Gray's mouth.

Rather that shoving harder, Gray reacted positively and kissed back forcefully. He snaked one hand up into Natsu's pink hair to force their lips closer, and the other down to the small of his back to press their bodies closer together. He fought for control of the kiss, but after about a minute he needed air. Gray broke the kiss and they both gasped for air.

Once he got his breath back, Gray moved his hand from the small of Natsu's back to the dragon slayer's wrist, flinging him onto the bed, and crawled up onto of Natsu where he straddled him. Putting his hands on either side of Natsu's head, Gray kissed him again, Natsu's hot lips against his own cool ones. Just when he got into it, the world rotated and suddenly Gray found himself looking up at Natsu, instead of looking down.

"Oh no, you don't really expect me to be the bottom do you? Not to anyone, not to you," Gray protested, but that all stopped when all thoughts on the matter flew out of his head when Natsu kissed him again, his tongue exploring Gray's wet orifice. Gray felt his body warm in temperature as his heart beat faster. And then Natsu ended the kiss all too soon for Gray's taste and Gray's lips immediately felt cold without Natsu's overly warm lips against his. Gray started to sit up so he could press his lips to Natsu's again, seeking that heat he found himself craving, but Natsu ran his fingers down Gray's back, scrapping his nails down Gray's spine.

"Ah!" Gray's eyes flew wide as the odd sensation sent shivers down his spine and he arched his back away from the Natsu's fingers. Gray's bare chest touched Natsu's all the way to the hips. Their groins bumped and Natsu made a satisfied sound. Pleased with Gray's response, Natsu rewarded Gray with a kiss. And Gray began thinking he could really get used to this body heat…
