Summary: Inspired by a scene in How I Met Your Mother. Natsu takes Lucy's words too seriously.

Pairings: Natsu/Lucy and a little Gray/Juvia.

YouTube Prompt: A tribute to the strained relationships between Lucy and her father, Laxus and his father, Edo-Jellal and his father, Ultear and Ul, and Gray and Lyon, to the song Just Like You by Three Days Grace.

It was a nice day and they had just succeeded in defeating a hoard of monsters. Therefore it was natural for them to celebrate by blowing some of their reward money (which for once they managed to receive in its entirety) on a feast. Natsu and Happy were scoffing majority of the main courses, Happy enjoying a large variety of fish (most of which made Lucy want to vomit) while Natsu was devouring meat dish after meat dish. It was then when Lucy decided they could pay for the main course because there's no way in hell she was footing what was bound to be an incredibly expensive meal.

"You're guys are paying for that!" she barked out to them. "Some of us have rent to pay!"

"But Lushy," Happy said through a mouthful of food, "You're eating too!"

"I'm just eating one meal not the entire fish section," Lucy pointed out.

Happy pouted. "You could eat more," he said miserably, "we don't mind sharing with you, Lucy!"

Lucy felt a tiny bit guilty at that. Of course they don't mind sharing and in that perfect world of theirs, she would share the expenses as well. "I'm not that hungry for fish or meat now," Lucy said, "but I am up for a pudding. Tell you what, you pay for this, and then dessert is on me," she winked at the blue cat.

Honestly it was an evil deal so totally in her favour. Natsu and Happy weren't big on sweet stuff so she could get away with just buying three ice creams and not spending a lot of her money.

"No thank you, Lucy," Happy said looking rather disturbed, "I'd much rather eat my pudding in a bowl."

"I didn't mean literally you stupid cat!"

"Wah! Natsu, help! Lucy's being meaaaaaaaaaaaaaaaaaaan!"

"Shut up, you're causing a scene!" Lucy hissed embarrassed.

Natsu swallowed his chicken leg whole (urgh….) and looked up at them, puzzled. "Huh?" he said completely oblivious as always. "What did you say, Happy?"

"Nothing," Lucy said before Happy could speak, "he's being stupid like always. Do you want anything for dessert? It's on me."

Natsu grinned brightly. "Sure! Can I have a hot fudge sundae?"

"Why not?"

"Awesome!"

They finished the rest of their meal in peace and Lucy left Natsu to pay for that before they headed over towards the ice cream parlour for their dessert. In childish revenge for Lucy making him pay for the main course, Natsu ordered the biggest, most expensive, hot fudge sundae that the parlour had to offer.

Lucy had no idea how truly stupid Natsu was until the waiter served them their ice cream, and the pink haired dragon slayer turned and grinned at her, "Come on then, Luce," he said rather patronising, "get your clothes off."

"WHAT?!"

"You said dessert was on you, but I know you, Lucy, you don't like it when your clothes get al mucky," Natsu explained impatiently, "So c'mon then, strip, before my pudding gets cold."

"I DIDN'T MEANT LITERALLY!"

"Ah! Happy! Lucy is backing out of her promise!"

"Pin her down then!" Happy suggested evilly.

"What?! Don't you d-"

Lucy didn't get to finish her sentence as Natsu pounced on her and tried to take her top off with one hand while the other held up his hot fudge sundae threateningly.

This of course does not end happily for either of them.

After all it is not fun explaining to Erza exactly why she had to bail Lucy and Natsu out for public indecency but still….Lucy wasn't the one being beaten to death for sexual harassment.

(She did, however have to deal with everyone's teasing, and she may or may not have snapped, and punched Gray in the face which led to her almost being drowned by an over-protective Juvia.)
