Summary: one-shot. Let's just say there have been a few incidents where Happy has come in at a bad time. Nalu

...

...

The blue exceed flew over the crowds of Magnolia; a look of pure determination on his face. Yesterday his two partners had gotten into a large fight. No one knew what it was about but it eventually caused them to go on separate missions for the rest of the day. Natsu wasn't happy during the whole trip and when they came back to the guild, he said he wanted to go talk to Lucy and left. He never came back and Happy ended up sleeping over with the Strauss siblings.

When he returned to the Guild, everyone told him that Natsu and Lucy had yet to return; which was why he made it his mission to find his friends and see what happened.

He flew past an alley and stopped. The cat blinked before flying back to the alley way.

There, locked in a heated battle of tongue wrestling, were Natsu and Lucy. The dragon slayer had the blonde pressed against the wall, his arms on either side of her head. She didn't seem to mind that she couldn't escape since her hands were wrapped in his scarf, pulling him in to continue their battle.

Kissing; Happy knew what that meant. It was what humans did to show their affection and right now his partners were showing a lot of it.

He grinned mischievously. "You llllliiiikkkkkeeee each other!"

The two humans pulled away; Lucy's face was glowing bright while small traces of pink lingered on the fire mage's cheeks.

Happy continued to fly over the couple, chanting that they both liked each other. The celestial wizard groaned while Natsu laughed. "You got that right buddy."

To say that Happy wasn't, well, happy would have been like saying Juvia doesn't love her precious Gray or Gajeel doesn't "secretly" like Levy. The blue exceed was pleased that his two human companions finally got over being dense and admitted their feelings to one another. He couldn't be happier.

Okay; he lied. When he told Mira about what he saw in the alley and was rewarded with a mountain of fish, he was happier than.

Months passed by and the Exceed continued to catch both wizards in the act of kissing. He would tease them, they would ignore him, which would cause him to cry and his partners would eventually stop and shower him with affection and fish.

Happy flew over to Lucy's apartment. He frowned when he saw that the window was locked and a curtain stood in the way from seeing what his partners were doing.

Rather than finding this odd, the blue cat pouted and entered through the bathroom window. 'I bet they were trying to keep all the yummy fish to themselves.' He thought, clearly annoyed with their 'inability to share.'

Exiting the restroom, he stood in shock and confusion as he watched what Natsu and Lucy were doing on her bed.

His 'father' hovered over the blonde; she was missing her shirt and his arms wrapped around her bare back. The dragon slayer had his mouth latched onto one her enormous breasts before he removed one of his hands from her back and groped the other boob. He watched as Natsu traced her nipple with his tongue before taking it back into his mouth.

Surprising, Lucy wasn't hitting him for touching her breasts like she normally does. Instead, she made weird expressions like she was having enjoying it yet wasn't smiling. She had her eyes closed and the pink haired male must have done something at that moment to make her moan. She wrapped her legs around his waist. She also ran her hand through his hair, making him growl possessively and suck on her harder.

Happy couldn't process what was happening. Mira never said any of this stuff when she explained human love. She only talked about kissing and hugging and flirting and where guys stare at girls and where girls look at boys but never about….this?! There had to be something wrong, but what was it?

Then it hit him.

The cat flew in circles over the couple as he yelled out "Lucy hit Natsu so hard that now he thinks he's a baby!"

Immediately Natsu stopped his suckling and the blonde screamed before knocking the dragon slayer off of her.

Still to this day, Happy doesn't understand why the fire mage was doing that to his girlfriend (or why he still does it) but as long as he keeps getting fish for not telling he doesn't care.

When the cat sees Lucy 'breastfeeding' Natsu, he finds it weird but figures that she must keep hitting him for him to still think he's a baby. However, in this situation he can't think of any reason why Natsu is sitting on the couch with the blond's head between his legs. Was this a new wrestling move that he didn't tell him about? No, he doubted it since it looked like Lucy had the upper hand.

Both of them are missing articles of clothing. For some reason, Lucy is playing with Natsu's 'boy part' with her tongue. He watched as the girl gave it a long lick before slowly making her way to the head, cleaning off the liquid and then putting most of his manhood in her mouth. The male threw his head thrown back; panting like Lucy does when he suckles on her. He was sweating; one hand gripped the couch pillow and the other was buried in her golden colored hair. It looked like he was keeping her head there. He kept whispering her name and when Natsu let out a groan, it sent Happy the wrong message.

"Stop trying to eat him Lucy! You're hurting him!"

The blonde girl choked and released her hold on him. Igneel's son quickly grabbed one of Lucy's pillows and placed it over his crotch. "Happy!" He yelped.

Both males worriedly stared at the girl who was still choking. Eventually, she managed to stop. When she did, she grabbed her shirt that was on the floor and sent the cat an annoyed stare. However, she sighed and put on her clothing before disappearing to the kitchen.

They heard her rummaging through the refrigerator and figured she was going to start dinner. Happy grinned. He smelled fish!

Then he remembered what he saw and turned to his adopted 'father.'

"Natsu…why was Lucy hurting you? Did she get mad cause you told she gained weight again?"

"I HEARD THAT YOU STUPID CAT!"

The dragon slayer merely smiled. "She wasn't hurting me Happy. Actually, it felt pretty good."

Happy frowned. He tilted his head to indicate he was confused. "How does putting your boy part in her mouth feel good? Were you trying to be a lollipop?"

This time Natsu blushed as he rubbed the back of his head in a nervous manner. "Ahhhh….LUCY?!" He called for assistance.

"DON'T LOOK AT ME! HE'S YOUR CAT! YOU EXPLAIN IT!"

After witnessing all the strange things Lucy and Natsu did in a bedroom…or in a hotel…or the forest…or pool….he came to the conclusion that the celestial mage had brought his long-time friend to the dark side and made him into a weirdo. (Seriously why did Natsu have to put his face between her legs? Isn't it hard to breathe?)

But by far, what he was currently watching was the strangest thing he has ever seen them do and he wasn't even trying to find them this time.

He figured that they would be at Lucy's apartment doing their weirdo things so he went home. However, when he got there he saw his partners on the couch. With his sensitive nose, he picked up the scent of sweat and something else.

From what he could tell, they were both naked. The fire dragon slayer covered the blonde with his own body; his hands were under her, keeping her against him. The girl clawed her nails against his back but he didn't seem to notice. Sweat trailed down both their bodies; their breaths grew louder as they continued to rock against each other at a fast speed.

"I'm...I'm coming!" The girl panted hotly.

"Me..me too." He wheezed.

Their grip tightened around each other.

"NATSU!" She screamed.

"LUCY!" The male roared.

A moment later they stopped moving. Both humans were still panting and Natsu shifted his position so that he can lie besides her. They still ending up tangled in each other's arms.

However, the Exceed was still rubbing his poor ears.

"Did you guys have to yell?" He complained. "You're right next to each other!"

This time when Lucy shrieked and unintentionally kicked Natsu off, the dragon slayer held onto her and both clasped to the floor.

"H-h-happy!" She squeaked while Natsu massaged his injured head. "H-how long were you there?!"

The blue cat shrugged. "Not long. Why were you cuddling naked?" The couple blushed and the Exceed gasped. "It's because you're both perverts isn't it?!"

"WE'RE NOT!" was heard the same time Natsu said, "Only for each other!"

Lucy smacked her boyfriend for his blunt statement.

Happy sighed. "Youngsters these days. I'm going to leave; it's starting to smell now. And I want two plates full of fish this time Lucy!" He yelled before flying over to the door.

As he was leaving, he heard his blonde friend ask the fire mage why couldn't he hear or smell him. Natsu told her that he was too into her to notice anything else. Then it got quiet. He left before the lip smacking and moaning began.

Honestly, the cat thought mischievously, youngsters these days, am I right?

A/N: Before I say anything else, I just have to yell out: I LOVED THE NEW FAIRY TAIL EPISODE!

(if you haven't watched it you probably shouldn't read this unless you want to be spoiled! so warning: SPOILERS) OMG! DEFINITELY one of my favorite episodes so far! First of all, loved the intro! One of the best intros so far in my opinion. Then, I just LOVE how this episode strengthened the bond between Lucy and her spirits! They are so important and I'm SO HAPPY that they finally have another episode with them! I LOVE the celestial spirits XD and then...the ending with Lucy and Aquarius! I wanted to cry so badly because if you've read the manga you know what happens next. And if that didn't leave me in a great mood, then the Fairy Tail ending topped it off! Idk why but I end up loving the Fairy Tail endings more than I do the openings. Weird...but I'm so excited for the next episode! I sense Nalu XD

omg...I'm going to be honest; recently I haven't been in the mood to write just because of the lack of Nalu or favorite characters (Lucy and all the celestial spirits are my favorite) in the manga/anime. But now: BOOM! Motivation has sky-rocketed! xD ahhhhh thanks listening X)

So now that's that out of my system, I have to admit I'm really nervous about publishing this. This is my first time I've released something that was Rated M and I feel like such a nube lol I'm so used to writing rated K+ to T that I'm scared some people might just look at me weird now for having this story up. Hopefully I haven't lost anyone's respect from this.

I heard about 'Nalu Love fest' from Absent Angel and since I missed Nalu week because of Anime Expo I figured I can write something to make up for it, hence my contribution to Day 1 of this online event. Prompt 1: First Time. In this case it was all of Happy's first times walking in our couple's intimacy time. XD I don't think this is what they meant by 'first time' but hopefully it works Lol

I've read stories where the child walks into the parents' bedroom and catches them doing the naughty but I figured I can use Happy with Lucy and Natsu. He's practically their son and since he's a cat I don't think he grasps how humans think sometimes. When Mirajane wears a bathing suit in one short, Happy blushes as he stares at her but Macao and Wakaba have creepy grins and heart eyes. My guess is he thinks she's pretty but isn't fantasying like Macao and Wakaba were. Also in that one Fairy Tail special with Juvia and the love potion, I think it's Warren and Max who comment on Erza's rival (which is a pillar) and Happy doesn't understand how it's weird (saying that it would make sense if Erza's rival was a caterpillar). Another example is when Natsu gropes Lucy and all Happy says in the English version 'youngsters are so bold'; I don't think he grasped the concept of what groping (especially when someone is naked) implies otherwise he wouldn't be so calm. But then again, sometimes he's more mature than Natsu so we know he's not entirely clueless. Let me know if you thought he was OOC or not please.

Please leave me a review. I want to know what you thought of my first Rated M story. If you liked it but don't know what to say, you can write me a smiley face and I'll take it as I did good. If you didn't like it, let me know where I went wrong.

Thank you so much for your support. If you're bored, you're always welcomed to check out my other Nalu stories.

Until next time (which will hopefully be Halloween),

Your friend,
