A/N: There is a picture on DA with the same title and pic inspired me but I can't remember their name. I would like to. Credit them. All I did was make a fanfic about it. Oh and I betaed this because I wanted to change it up so read again if you like.

Minutes that seemed like hours passed by as Yukio absent-mindedly watch his brother instead of reading his new shoujo manga (courtesy of Rin). Yukio took more interest in watching his Nii-San strut around the room playing with Kuro. Yukio couldn't help but stare at the tail. The way it'll stick up and sway like one of a cat's.

"A fluffy puff at the end as well." Yukio muttered to himself.

He watched as Rin's tail bounce with each movement he had, who is only fixated on playing with the small cat running around in front of him. His tail was proving to be a great annoyance to Yukio. He plopped the manga that was once in his hands on his desk before calling out to Rin.

"Nii-San..." Yukio stated pushing the front of his glasses closer to his face out of pure annoyance.

Rin looked up at Yukio as he let Kuro gracefully fall down onto the floor. "Hmm...?"He hummed turning to look at an irritated Yukio.

"Your tail is showing..." Yukio stated matter-o-factly.

The two exorcists looked at each other for a moment. One obviously confused and the other annoyed.

"This..?" Rin said as his tail curled up closer to his mid back-section. The puff straight in the air before curling at the tip of the fur. He began to let his tail sway once more. An anger vein popped on Yukio's forehead.

"YES!" Yukio shouted out of aggravation.

Long pause.

A few moments later Yukio pinned Rin to the ground and reached for the older twin's tail. Shocked by the sudden motion Rin broke his arms free. He blushed a bright pink at the position they were in and struggled to push Yukio off of him.

"Please stop struggling Nii-san!" Yukio said trying to stop Rin from struggling so much

"DON'T TOUCH IT!" Rin yelled, practically screaming. He was glad they were the only ones who lived in the old dorm.

"Nii-san…stop acting like a child." Yukio muttered loud enough for Rin to hear. Rin pushed Yukio once more desperate to him off.

"NO! BAD YUKIO! Leave my tail alone!" Rin screeched trying to pull Yukio off him once more. It was futile since the younger of the two is stronger. Rin cursed under his breathe cause of this fact.

Yukio had managed to get Rin's tail in his hand and tugged on it. "Nii-san if you won't do it then I will it for you-!" Yukio said before getting cut-off by a low moan from his older brother.

"AH! .Noooo~...Y-Yukio Let me go~..." Rin panted his face a flushed dark pink. His breathe came out in quick pants as his chest went up and down slowly. Saliva escaped his mouth sliding down his lips and down his chin. His eyes were tightly closed as he curled his hand in Yukio's shirt.

"!" Yukio paled, letting Rin's tail slip from his hand. Rin took this moment to push Yukio off of him. Frustrated and embarrassed he ran for the door.

'T-that was...' Yukio thought covering the obvious nosebleed he has.

"IDOIT! IDOIT! IDOIT! YUKIO! YOU'RE SUCH AN IDOIT!" Rin yelled before slamming the door leaving Yukio to his thoughts
