Chapter 1: An Ironclad Warning

While at first, it seemed like a normal friday night at the Fairy Tail guild, a peculiar meeting was taking place on the second floor. That meeting was between the three resident dragon-slayers Natsu Dragneel, Gajeel Redfox, and Laxus Dreyar.

"Alright, metalhead. What was so damn important you called us here?" Laxus asked.

Gajeel scratched his head, visibly awkward as he spoke up. "Have you guys been feelin'...weird lately?"

"Weird how?" Natsu asked.

"I mean have you seen or noticed or felt...out of the ordinary?" Gajeel asked. And to his surprise, both dragon-slayers gained a blush on their faces.

"Well, I don't know why, but all the girls have been smelling and looking really good lately." Natsu admitted with a shy expression.

"So it's not just me." Laxus said, palming his face with an embarrassed look. "My hormones have been acting crazy for two weeks. I can't even look at Cana without getting a stiffy."

"Hm. I think I know what's goin' on." The iron dragon-slayer said before taking off his left glove and showing his palm. Inside it was a silver dragon emblem with four iron spikes surrounding it.

"Holy crap! You got one too!" Natsu said as he removed his scarf, revealing an orange dragon emblem with six flames surrounding it on the right side of his neck.

"This is just plain weird." Laxus replied, pulling up his right sleeve and revealing a golden dragon emblem with five thunderbolts around it. "What the hell is happening to us, Redfox?"

"...we're in heat. And these are mating marks."

The two other dragon-slayer's eyes opened in shock. "You mean like how Happy gets in spring?!"

"...that little guy actually gets horny?" Laxus asked.

"Yup." Natsu replied as he remembered that incredibly awkward trip to the vet.

"Well, it's kind of similar to that." Gajeel replied, thinking he might need to take Pantherlily to the vet soon. "Basically, our dragonic instincts are telling us it's time to claim a mate or two."

"Or two?" Natsu asked. The black-haired man then pointed his mark.

"Apparently, each of the elements on our marks shows how many mates we can have. So I can have four, flamebrain can have six, and you, Laxus, can have five mates."

"One mate would probably be a pain in the ass. I can't even imagine dealing with five girls." Laxus grumbled.

"So that's why I've been feelin' weird? My instincts are telling me to...do it with six girls." Natsu said, his cheeks aflame.

"Yes. But I don't think we should act on them." Gajeel said with a serious expression. "When Metalanica was tellin' me all this years ago, he said that our bodies would also admit 'dragonic pheromones' that would do something...weird to our mates."

"You wanna be more specific?" Laxus asked.

"That's all Metalanica told me!"

"Did he say how long we'd be like this?" Natsu asked.

"No. But I'd wager we'll probably be back to normal by the end of the month." Gajeel explained.

"So we just gotta ignore our hormones for a few weeks? That's easy." The salmon-haired dragon-slayer said with confidence.

"Damn, Lucy! I think these puppies have gotten bigger lately!"

"C-Cana, stop!"

As the three dragon-slayers looked down from the railings and saw a drunken Cana groping Lucy's generous bosom, they realized that ignoring their dragonic mating instincts would be easier said than done.

'Dammit,' The three thought to themselves, unaware of just how different their lives would become in a few weeks.

To be continued…

Author's Note: It's been a while, guys! I've been in kind of a slump creatively. I'm still trying to figure out what I want to do next with the Pro-Hero's stories and my Naruto Bodybuilder AU seems to be going nowhere. So, I decided to revamp my Fairy Tail stories with a different idea, rather than just copying Pokkuti's Magic Muscle: Pheromone-induced Female Muscle Growth!

Basically, this is me taking the lessons I learned from 'Pro-Hero's Muscular Harems' and bringing them back to Fairy Tail. Including more diverse muscle size and tone for the girls (which was kind of a problem I had with Muscular Maidens). And this includes letting you guys determine the harems by poll. And the first one is for deciding which Fairy Tail girls will buff up and become Natsu's mates. The choices are as follows:

Erza, Lucy, Juvia, Lisanna, Ultear, Meredy, Mirajane, Cosmos, Evergreen, and Laki!

Each individual voter can vote for six girls. And the six girls with the most votes will become Natsu's mates!

So cast your votes, and have a safe and pleasant day!
