AN: I don't think this is M rated or anywhere near it, but to be safe, I have to say that... well, it's not steamy but… Well, read on and tell me!

This one I based off with NekoMaji's review! She said: "What about a naughty ones like they are goin in Honeymoon or something.. Juvia is wearing a seductive clothes or she's doing something that can make someone arouse like Gray.. Im a pervert so good luck! XDD"
I never wrote something 'hot' before, so forgive me if it's not good! :I Anyway, here's the chapter!

Special thanks to Ulcaasi, who pretty much beta-ed this chapter by pointing out my mistakes!

Forgive me, Father

Gray knocked on Juvia's door and waited her response, which was after a few seconds. He sighed and waited for her to open the door. He forgot the damn key she gave him, so he needed to wait. And he was looking ridiculous.

They were going to Mirajane's costume party and Gray wasn't in the mood for picking a costume so he put black pants, a black shirt and cut a piece of paper. Then voila, he was a priest. He wasn't going to be the hottest man there, but well…

Juvia opened the door and before he could say anything, she was back into her apartment, looking for something. "Sorry, Gray-sama. Juvia will be finished in a second."

"It's okay." He sighed and entered the place. He knew everything inside it already, so he just threw himself at the sofa to wait for her. They were just in time for the party and Juvia normally was in time for everything, so he knew that she was not going to take much longer to get ready.

After about two minutes, Gray was staring at the ceiling very interested in one spot that looked like a snowflake. It was kind of funny. And the spot next to it, looked like a… well, nothing really. Gray was just really bored.

"How does Juvia look, Gray-sama?" He heard her and sat looking to his girlfriend of eight months and he was shocked to say the least.

She was… She was… hot.

Her hair was in twin tails and her bangs were falling into her eyes. She was wearing a white shirt that barely reached under her breasts, showing her flat stomach; a blue small tie and a tiny, tiny Scottish blue skirt. She was using some white socks that reached her knees and black shoes. She was a school girl.

No, scratch that. She was a hot school girl.

She wasn't supposed to be dressed like that! That outfit wasn't supposed to be that sexy. She was showing too much skin! And since she was his, she was showing his skin!

"What the hell are you wearing?" Was the only thing he managed to say as the room grew hotter.

"What's wrong with this outfit?" Juvia asked innocently looking down to see what was wrong with it. Wasn't she looking like a schoolgirl?

"You…" Gray couldn't take his eyes off of her clothes. "You shouldn't wear this to go out on a party, Juvia!"

"What?" She frowned and her head fell a little to the side, confused. " What would I use it for, then?" Gray groaned. He didn't want to have this conversation with her! "Cana-san said that it was…"

"Cana?" Gray frowned.

"Yes. She was with Juvia when she bought this." The blunette said looking down again. "Cana-san said that you'd like it."

Gray liked it, alright. Maybe he liked it too much and there's no way in hell that he would let her go outside looking like that! And the worst part was that she had no idea of the effect she would cause if she actually stepped out of her apartment looking like that.

"Juvia, you need to go change." Gray sighed, blushing. "This outfit was not made for… parties."

"Really?" She was the spitting image of innocence. "Now I just feel silly using this." She pouted, looking cuter.

"You don't look silly." Gray said looking with appreciation to his girlfriend.

"Then why can't Juvia go to the party with it?" Juvia didn't understand what was happening! If she wasn't silly, then she could go to the party with it, right?

"Because!" Gray got up.

"Because what?" She frowned.

"This is an outfit to play, Juvia!"

"To play what?" Juvia was exasperated at that point, looking to her boyfriend like he was crazy.

"Juvia, the skirt is so small that if you bend a little, people can see your amygdalas. What do you think this outfit is for?" Gray said and they stayed in silence for a few seconds.

Her mouth formed an 'O' as she finally understood what he was talking about; she was wearing a costume for foreplay. For, you know… sex.

"I see." Juvia nodded slowly.

"So, go change. Find something else. We are going to be late." Gray looked away, red as a tomato. They were dating for eight months at that point and truth be told, they didn't wait too long to do the deed. Actually, that was what date number four was all about and since then, their sex lives had become very regular but the subject still made Gray highly uncomfortable, the opposite of his girlfriend, who spoke about it very openly.

"Why change, Gray-sama?" Her tone changed to a silkier one and his insides twisted a bit; that wasn't going to end well. "Doesn't Juvia look good?"

"You look… fine; but you can't go out wearing this." Gray looked up to the ceiling, trying very hard not to think about his very hot girlfriend wearing a schoolgirl costume.

"But Juvia is all dressed up now." She stepped closer to him and pressed her body with the side of his. "She thinks it's a waste to be all ready and not to enjoy it."

Gray started to think in cool things but it wasn't really doing anything, since the warm body pressed into his was way more interesting than his mind screaming: 'ICE, ICE, ICE, ICE, ICE!'

"Juvia…" Gray was staring at the ceiling, to the spot he thought looked like a snowflake and trying to concentrate his blood on his head, not down below the belt. "We were supposed to go to the party."

"But Gray-sama…" She started to give small kisses on his neck. Gray was a tall guy and Juvia had the exact height to be giving his those kisses. "We can arrive a little late."

'Yes! Yes, we can.' Gray's body yelled but his mind was still very much indecisive yet.

"If we do…" A kiss in his pulsating point. "Oh, god. If we do get there late, people will…"

"No one will notice." She was on her toes now, her lips very close to his ears. "C'mon, Gray-sama. Aren't you curious about how will be like with this playing thing?"

Fuck yeah he was! That was clearly what he has been thinking about since he put his eyes on her dressed like that. Since they got together in the biblical sense, Gray knew that Juvia was always up for it if he was and he could barely keep up with her. Truth be told, he really didn't need another reason to excite her, but this time, he was just as excited as her.

"We're going to be late…" He protested and before he could say more, Juvia let him go and pushed him into the couch, making him fall seated in it.

"Juvia didn't hear a 'no'." She said and took a step closer to him and Gray could see again the outfit. And his mouth dried.

She sat on his lap and he groaned. Damn, he was close to giving in to her. He was going to protest, he was going to try something he truly was, but everything he thought he would do vanished from his mind once she leaned closer to him.

She was wearing the purest expression in her face, but her pupils were dilated. Oh, man. She was aroused and he wasn't much behind.

"Forgive me, Father. I have sinned."

Holy mother of…

He was a dressed as a priest. And she was a schoolgirl. Oh, man. That was kinky. That was very, very kinky. And he would be damned, because he liked it.

Gray groaned again but now it wasn't with annoyance, it was anticipation. She managed to wake his whole body with just those words. He tried to fight it. They were late to the party and if they didn't show, Erza would kick their asses and Mira would cry, but he wasn't exactly thinking with his brain at that moment, that's why the words he proffered were very, very wrong and after them, it had no turn back; they were going to go until the end.

"What have you done?" His voice came out a lot steadier than he was actually feeling.

With those words, he could clearly see in her eyes that he had said the right thing.

"Juvia had been doing bad things, Father." She pouted and leaned into him, making their chests touch. "Very bad things." She was talking slowly and her face was close to his and his mouth dried even more. "And she still wants to do bad things."

Gray's hands were in her thighs and so very slowly he was making them go up into her body, making her shiver. Feeling a little bit more confident with the reaction he got from her, Gray rested his hand in her lower back, while the other was finding its way to her neck.

"And what those things would be?" He asked, eyes locked into hers, filled with promises. "You can tell me, I won't judge."

Juvia smirked and Gray shivered. Oh, he knew that smirk. Things were going to get interesting.

"How about Juvia show it to you?" With that, their lips collided and sparks flew everywhere. During the time they were together as a couple, they never role played and he was starting to think that they lost hours of fun. Since she was very open about her sex life, people knew that Juvia would probably be without inhibitions in bed, but Gray was something else entirely. Because of his cold exterior and reaction every time the 's' word was said, it let to people to believe that he may be a little frigid.

They were wrong.

Juvia knew exactly what buttons to push, what to say and where to touch to resume the icy man to a pool of boiling water and he wasn't sure if he would ever find anyone else to make him so crazy with just a few words or a look. And hell, he wasn't going to let this one go away.

About one hour and a half later, Juvia and Gray entered Mirajane's apartment, where the party was being held. The saw Natsu pass by them wearing pants, underwear outside, a black shirt and a red cloak? What the…?

"What took you so long?" Erza, who was wearing a Jessica Rabbit costume, asked as soon as the couple entered Mira's apartment, scaring them a bit.

"She didn't find her costume." "The car broke down." Gray and Juvia said at the same time.

Erza frowned and Juvia looked up to Gray, who looked back to her, a little alarmed. If they arrived late because they were having scandalous hot sex, Erza would really beat them up. Not that he was regretting.

"Juvia didn't find her costume and then the car broke down, but it's fixed now." The girl smiled to Erza, as naturally as she could.

"I see." The red haired woman nodded, understanding. "Gray, you are clearly a priest. And Juvia, are you a princess again?"

Juvia and Gray agreed that she wasn't going anywhere with a school outfit. Lucky enough, Juvia still had her costume from the first party she ever went with them three years before: a princess outfit. With the little time she had to find something else to wear, she was lucky to find that. And with her hair longer, Juvia put her tiara on and could wear her hair loose, since the first time her hair was way shorter. And when she had nothing else to do, she liked to sew, so the dress was now sleeveless.

"Yes." Juvia smiled. "The other costume Juvia bough was a little too… small for her." Gray coughed. "And with the final exams coming in college, she didn't have much time to find another one."

"It's quite alright." Erza said smiling. "First you need to pay attention in college. And you look very good, Juvia."

"Thanks, Erza-san." The blunette smiled and grabbed Gray's hand. They told Erza that they would walk around a bit.

Gray was nervous, looking around.

"Calm down, Gray-sama." Juvia chuckled. "No one knows."

"It feels like they do." Gray mumbled and they finally found their friends. Lucy was wearing a Supergirl costume, Levy went as Batgirl, Gajeel was Batman and Natsu…

"What's Natsu supposed to be?" Gray frowned, looking at the pink haired man, who was talking/fighting with Gajeel.

"Captain Salamander." Lucy sighed.

"That doesn't exist." Gray said.

"It doesn't. He forgot about the costume and today he just ripped his curtain to make the cape, put his underwear above his pants and draw the stupid moustache on his face with a marker." Lucy sighed. "At least he's having fun with his outfit." At that moment, Natsu let out a 'Muahahaha' and then started to laugh.

"Hey Juvia, what happened to the one we bought together?" Cana, who was wearing a gipsy costume, appeared from behind them.

"It's…" The blunette blushed a little, while Gray looked away as red as a ripe tomato. "Juvia decided not to use to the party."

Cana frowned and then looked to Gray, who was almost black with the redness and she smirked knowingly.

"I see. Not at the party." She turned around to leave, laughing. "You can thank me later, Gray!"

"Shut up, Cana!" Gray yelled, still red faced and Juvia chuckled. "And you! Don't encourage her!"

"Fine…" Juvia grabbed his arm and looked up, smiling. "…Father." She smirked when he groaned.

"Damn. That freaking costume is going to be used again." Juvia laughed and stood on her toes, giving Gray a peck on the lips.

"Juvia is sure it will."

AN: Okay, I made Juvia look like a sex addict. But if we think, she's the one who's always thinking about it, so I guess it was fitting.

Erza would look freaking gorgeous as Jessica Rabbit. Just saying. And Lucy as Supergirl? Erm… awesome! Levy as Batgirl? SO CUTE! I liked it. How about you?
