A/N: I don't own Fairy Tail (although I wish I'd own Gray). Btw, English isn't my native language and I don't have a beta, so if you any see errors, please tell me. The characters may be OOC, especially Lucy.

Warning: Rated T because of suggestive themes.

Gray would always get pissed of when Erza would punish him just because he was walking around naked. Really, that wasn't his fault at all! He only developed such a bad habit because of Ur's unorthodox training methods and because he was so accustomed with the cold that the days that were so unbearable hot he couldn't handle being clothed even for a second.

But that wasn't what really mattered, Gray thought while trying to move his hands that were chained to the bedpost, what really mattered was that he really hated Erza's punishment, and that was it.

Besides, he thought before having his thoughts interrupted by the sound of a whip, a small smirk showing up in his lips, Lucy's punishments were way better than Erza's ones.

"You have been a bad boy, Gray. Now I'll have to teach you how to behave properly."

A/N: Ok, that's the first time that I write a fanfic in English and actually post it, so I hope that it wasn't that bad ^-^'! I got the "Ur's unorthodox training methods" on the Fairy Tail Wiki, in the Trivia section.
