Clothes

It was no secret that Gray had a stripping problem; it was an internationally accepted fact really. So it comes as no surprise to anyone really when they see him jaunting about in his underwear or even naked. Because while no one—except maybe Juvia—particularly liked seeing the Ice Mage in such a state all the time, they'd all learned long ago to simply roll with the punches when it came to this issue and do their best to not make eye contact. After all, Gray's stripping problem most certainly wasn't fixing itself anytime soon.

However, it wasn't until after Natsu and Gray had started dating that the full gravity of just how many people had actually seen his Gray naked had struck Natsu rather harshly over the head with a bat.

And oh dear did that not settle right.

He held his tongue on the matter—or at least as much as he did before they were dating—and simply tried to subtly keep Gray's pants on more (outside of their respective homes that is). He didn't get very far very often; or at all in general really. And although he eventually settled for just trying his best to grit his teeth and moving on from it, Natsu eventually reached his absolute breaking point when he was journeying to Gray's house one day only to find one of those door-to-door sales chicks flirting with his Gray who seemed to be completely oblivious to the fact that he was naked.

When Natsu had stopped seeing red and fire (and stopped trying to kill the female who had been trying to lay a perverse on his man), he turned his many pent up and frustrated sights on Gray. Though he couldn't much understand all of it, Gray managed to finally—finally—grasp the problem at hand.

The problem, again, being that Natsu wasn't the only one seeing Gray naked.

Upon coming to full realization of this fact, Gray then silenced Natsu in the only effective method he knew how: kissing him until he stopped 'resisting' and mumbling 'Stop trying to seduce me you pervert' between liplock. When that was settled, Gray pulled back and looked Natsu dead in the eye before saying, "I'll try to, at the very least, keep my underwear on if you promise to do something about the vest."

Natsu was momentarily confused before looking down to see Gray running his hands up and down Natsu's toned and very much revealed abdomen and chest. And from that day forward, Natsu wore a single-sleeved, closed coat and Gray made a very conscious and constant effort to keep his clothing on (outside of his and Natsu's homes that is).

Beds

Whenever Natsu and Gray got up to their more indecent activities, one way or another and at some point, they always ended up in one of their beds (depending on whose house they were at). And when they did end up in those beds, things got hot—literally and figuratively.

See, when things get a bit intense Gray and Natsu exude a small amount of magic. It's never anything bad (they actually find it more arousing actually), but it still causes a few minor issues.

So, a couple of months after the two opposing mages' relationship finally took a turn for the romantically intimate, they finally managed to convince Freed to write ruins into all their pillows, sheets, mattresses, and covers in general so that they could resist and withstand extreme temperatures.

Sorry this took so long. I am a horrible person. These actually weren't what I originally wanted to post but I had them in my book so I was like, 'what the hell', and now here they be. So yeah. Sorry again.
