A/N: Hello, I'm very sorry for the late update. I actually stopped watching Fairy Tail a long time ago and I wasn't going to continue this because it is a one-shot after all, but people asked for another chapter and I didn't have anything to do today, so I wrote it.

Since I have not watched Fairy Tail since Michelle (Lucy's "cousin") was introduced, characters may be OOC, which I apologize for, but all of this is written from my blurred memory of the characters.

I also edited the first chapter after re-reading it, nothing major.

And yes, using cake as lubricant is unsanitary, but this is a fanfiction and anything can happen in a fanfiction.

Please enjoy.

Disclaimer: I do not own Fairy Tail.

"Where the hell is she?" Gray muttered under his breath after looking through the guild for a certain scarlet-haired knight.

"Who are you talking about, Gray?" Mira's voice came from behind.

Mira knew exactly who Gray was talking about. She overheard his conversation with Erza last night at the party and knew that a certain pink-haired friend was boiling with jealousy as they conversed.

~.~

Last night…

After she took Happy home, she walked back to the guild giddily. She just hoped she wouldn't interrupt anything. When she reached the guild, she slowly opened the door and peeked in. Her eyes widened in surprise at the cake-smattered walls and furniture.

"I thought I told him not to make a mess," Mira grumbled in her head. She walked in, but she couldn't find either of the two mages. She turned the corner of an upturned table and saw them and the position they were in. She smirked before she grabbed a nearby tablecloth and covered them with it.

"Wake up!" Mira yelled in their ears. Erza and Natsu jolted awake from their short nap, separating themselves, and both instinctively grabbed the cloth closer to their bodies. Before either could open their mouths, Mira spoke.

"You two should wash up in the guild's showers. I'll clean up around here." Erza nodded and pulled Natsu with her. "And no playing around in there, got it? Our friends take their showers in there, too. Think about that before you two act on your own needs."

They blushed and briskly walked to the showers. Minutes later, Mira heard low moans coming from the bathroom. "Of course…" Mira smiled as she swept with her broomstick.

~.~

Back to present day…

Gray turned around to find Mira in the bar area, wiping one of the glasses with a piece of cloth. He walked towards her and took a seat.

"Master gave Erza and me a new assignment yesterday and we were supposed to leave early in the morning," Gray sighed. "Well, I suppose I didn't give her an exact time, but she should've been here by the time the guild doors opened."

"It's 7:30 right now. If she doesn't come in the next ten minutes, then you could pick someone else to go with you," Mira suggested. "I'll let the master know that you changed your partner for this one mission."

"Thanks, but who can I find on such short notice to pack up his bags and leave in thirty minutes?" Gray questioned.

"Well…" Mira hinted as she tilted her head to look at the person behind Gray.

Gray furrowed his eyebrows in confusion and swiveled around on his chair. Staring back at him were two big, familiar, blue eyes.

"Juvia would love to help Gray-sama!" Juvia blushed as she stared at the ground.

A few minutes ago, Juvia was hiding behind the plant to observe Gray's godly profile and she saw him talk to that white-haired girl. She never saw her as a threat before, but if she made any moves on Gray, Juvia would have to keep a closer watch on her as well. She was glaring at them in jealousy until she heard that Gray needed to find a partner soon and Juvia took that opportunity to get closer to him.

"That's great! See? Problem solved. I'll let the Master know," Mira chirped.

"W-wait, hold on—"

"Gray-sama, I'll go pack right now! Please give me ten minutes!" Juvia interrupted him and ran out of the guild faster than the speed of light.

Gray sighed and rested his head down on the table.

The rays of the sun spilled into the bedroom through the window of Erza's apartment at Fairy Hills. Erza squinted at the blinding light before trying to turn around and face the other way when she noticed that she was stuck. She looked down and blinked at the masculine arm wrapped around her waist. Immediately, memories of last night flooded her mind.

She remembered Mira finding out. She remembered walking out of the guild with Natsu and how she sneaked him into Fairy Hills. She didn't want anyone to know…yet. And she remembered the sex. And the second time they did it. And the third.

They briskly walked to the showers in the guild and walked into the male and female bathrooms, respectively.

Erza turned on the faucet for the showerhead in one of the cubicles and took off the remainder of her clothes. She tested the temperature of the water with her hand before stepping in. The water ran down her body as she combed the frosting out of her hair. She closed her eyes as she relaxed under the pressure of the hot water. She let out a content sigh.

She tensed up when she felt two arms wrap around her waist before realizing who they belonged to.

"Natsu, shouldn't you be showering?" Erza asked without turning to look at him as reached for the shampoo. Before she could touch it, another hand grabbed her arm and pushed her against the shower wall. Natsu's lips crashed into hers, but Erza wouldn't have any of it and pushed her hands against his chest until he broke away…from her lips at least. His lips were still attached to her as he nipped and kissed down her jaw and neck.

"I thought it would be better if I showered with you," his eyes held a suggestive glint.

"But this cubicle is so small; two people can't fit in here," she tried.

"Well then, we'll just have to make us fit." He placed his lips back on hers.

Erza felt his hard member press against her clit and groaned into him as she kissed him back. He left her lips and made his way down to her breasts. She moaned as he palmed them in his large hands and tweaked her nipples with his teeth. Natsu licked and teased them while he slid his member against the clit and lips of her pussy.

Erza ran her hands through Natsu's hair and breathed heavily as he busied himself. She could feel her nipples and clit swell from the attention Natsu gave them. She removed one of her hands from his hair and moved it behind her to touch the tip of his member that was rubbing against her before wrapping her hand around it.

Natsu groaned into her breasts as he rubbed more furiously against her. Erza slid her other hand down his torso, feeling the tightness of his abs, and down to his balls. Her hand gently massaged them while her other hand trailed down his member. Erza started to roll her hips to the rhythm and went faster when Natsu went faster. This sent him into overdrive and Erza's eyes rolled back from the immense pleasure caused by the speed he was going at. They both moaned loudly as they reach their peak.

"NATSU!" Erza screamed as she climaxed.

"Erza" Natsu groaned, followed soon after.

The memory of it was enough to make her wet and aroused.

She turned her head to look back at the snoring dragon slayer with his mouth wide open and admired the features of his face with appreciation. She was in the middle of wondering how his pink spikes stood up even while he was sleeping, when she noticed the alarm clock on the nightstand behind him.

"Shit," Erza silently swore at the time. Gray was waiting for her. She was about to get up when she noticed she was still stuck.

"Natsu!" she screamed in his face. She had to hurry. She was needed elsewhere right now.

Natsu groaned, but didn't loosen his hold on her.

"Damn it. I didn't think I would have to do this." Erza ripped his arm off her body and threw him to the other side of the room.

Natsu immediately woke up. "What? What happened?!" he yelled. "Erza?"

The scarlet-haired knight walked around the room, throwing everything in a bag she would need on her mission with Gray. "I have to go. Gray and I have another assignment." Luckily, she didn't unpack too much from the mission they came back from yesterday.

Natsu's eyes immediately darkened at the mention of his ice mage friend. "Again? But you two just came back from one."

"Yes, but the master requested us to go on another one," Erza replied.

"But—why is it always you two? Why can't Gramps give it to another team?" Natsu demanded to know. "Why can't I come along?" He wanted to spend time with Erza and he also didn't want Gray getting his dirty paws on her.

"If you come along with us, we're bound to destroy the whole city," Erza thought back to the countless times they demolished the place instead of saving it.

"I promise I won't stand in your way. Or do anything."

"Then what's the point of going?" she asked. She looked at the clock once more to see that she only had ten more minutes to get to the guild in time and leave with Gray. "Sorry Natsu. I would much rather be here with you, but I have to go."

She turned to leave and quickly walked towards the door when she felt a hand on her forearm, stopping her from touching the doorknob.

"Then stay with me," Natsu growled as he placed his lips on the tip of her ear.

Erza felt her ears turn bright pink and her body unintentionally shiver at Natsu's low voice in such close proximity. She really wanted to, but she couldn't. She had to go. Then, she felt him poke at her lower back. He started to rub himself against the curve of her ass as he stabled himself by dropping his hands to grab her hips while Erza steadied herself by leaning her hands on the door. They both let out a deep moan.

"N-Natsu, stop it. I need to g-go." Erza moaned out.

"You don't sound like you want to go," he smirked against her skin.

He sucked and bit from her collarbone to her neck and up to nibble at her ears. He continued rubbing her with his hardness as he brought his hands over her hard stomach and laid them on top of her breasts. He felt her burgeoning nipples underneath his hand and smirked. She wouldn't leave in the middle of being this aroused…would she?

Natsu didn't want her to leave, so he quickened his pace.

"Remember last night? After the shower, you sneaked me in here. Then you gave me the best blowjob ever and as a reward, I fucked you senseless into the night." Natsu groaned into her ear to make her remember.

Erza certainly remembered. She was getting hot and sweaty just from the thought of it. "Mhmm…" she mumbled to let Natsu know to keep telling the story.

"I was already hard for you when you took off my pants. Then your small pink tongue darted out to lick the tip quickly before trailing it slowly along my shaft." One of his hands left her breast and made its way under her skirt. "You are such a tease," Natsu whispered as he slowed down his rubbing and played with her lace underwear.

He reached his hand in and stopped just before touching her clit. "And you tentatively sucked on my balls, giving both a good amount of attention."

"Natsuuuu…p-please…hurry," Erza raked her nails against the door. She needed to be filled now.

"Then you kissed—" Natsu nipped at her collarbone. "—up my shaft until you reached to the tip again." He started to rub her clit at a steady pace.

Erza groaned at the pleasure she was feeling. His fingers were on her clit, his other hand on her breast, his lips on her skin, his member still slowly rubbing from behind.

"Without a moment's notice, I was enveloped by the heat of your delicious mouth. Up and down, up and down, as you lightly dragged your teeth and swirled your little pink tongue around my cock." Natsu rubbed at her clit faster. She was at her brink until, "And I came into your mouth" and he stopped rubbing completely.

Erza groaned at the loss of friction. She almost had it, but he slipped his fingers out of her underwear. Natsu turned her around to face him and slammed his lips against hers.

"For making me feel so good, I felt it was my responsibility—" he spoke against her lips as he hastily took off her clothes, "—to make you feel the same way." Erza wrapped both of her legs around Natsu's torso and leaned against the door. "Ready for Round Two?" he smirked as he placed his member at her opening. He pushed the tip in when…

"Erza!" a voice yelled from the other side of the door. Both of them froze in their spots, not daring to move a centimeter. "Erza, it's Mira!" the voice came back. "I came by to tell you that Gray already left for the mission. Juvia offered to be his partner for the day and the master knows already, so no need to hurry." The last part was said with implications.

"U-uh okay! T-thanks!" Erza choked out. She felt so exposed.

"All right. Goodbye then. Also, tell Natsu I said 'hi'!" she yelled back through the door. On the other side, Mira was smirking and shaking her head, but turned to walk away. Honestly, she could hear the noises from a hundred feet away!

Neither paid attention to her last comment and Natsu rammed the rest of him into Erza once he heard 'Goodbye'. Erza moaned as her head fell in the curve of Natsu's neck and collarbone.

~.~

"Remember what Mira said?" Erza began the conversation as they fell back on the bed after what had happened by the door.

"What?"

"Don't you feel the slightest bit guilty for doing it in there—where the guild members shower and clean themselves?" Erza asked.

"Don't worry, Erza. No one will find out. Mira won't know. Our friends won't know."

"But—"

"Besides, how do you know that no one hasn't done anything in there before us?" Natsu smartly questioned.

Erza sputtered at Natsu's reasoning and blushed. "Well, I don't—"

She was interrupted by his lips.

"Gray-samaaa," Juvia sighed lovingly as she clung onto his arm.

Gray massaged his forehead with his fingers. "Whatever Erza is doing right now, it better be worth it."

A/N: God, the OOCness killed me. Ugh. I started writing it and then I lost inspiration to write it, but continued just because I already started it. Again, sorry for the late update.

By the way, Erza would have totally been dominant, but I already made Natsu seem like the dominant one in the first chapter and I didn't know how to change that throughout this chapter, so I just kept with it. Honestly though, how sexual can Natsu be? I think I over sexualized him in this chapter waaayyy too much.

I also do not know if there are showers in the guild. I just wrote it in there for convenience.

I'm not satisfied with the ending.
