The bell rang signalling the end of class.

"Nii-san! Suguro! Come here a minute!" Yukio called.

Bon glared at Rin as they packed up their things, "Whatever happened, it was your fault!" He growled.

"Yeah right! It was totally your fault!" Rin argued.

"Shh!" Yukio hissed, "Neither of you did anything!"

Rin and Bon trudged up to Yukio's desk.

"I have a mission, so Suguro, I want you to help Rin with his homework." Yukio explained.

"Why do I have to do it?!" Bon asked angrily.

"Yeah! Why him? Can't you get someone else?" Rin asked.

"Suguro is the smartest in this class, so no..." Yukio pushed his glasses up his nose, "...I can't get anyone else."

"Stupid four-eyed mole-face..." Rin muttered, walking away.

"Be patient with him." Yukio said.

Bon nodded and hurried after Rin.

"Alright, let me have a look." Bon said, holding out his hand.

Rin handed the sheet of paper to Bon, "Here."

Bon read through it and sighed, "Astaroth is the King of rot, not fire, that's Iblis, and
Beelzebub is king of insects, Amaimon is king of earth."

"Damn it!" Rin cursed, slamming his fist on the desk.

"Calm down! If you actually listened more in class instead of sleeping you might gotten
those questions right!" Bon suggested.

"Well I'd rather be outside doing something, than being cooped up inside a classrooom and having to listen!" Rin argued.

"You piss me off!" Bon shouted, standing up.

"You piss me off too!" Rin snarled back, showing his sharp teeth, his tail lashing back and forth.

Bon glared at it. It was like a somewhat fast metronome and it was hypnotising. He grabbed the tail and Rin yelped, "Ow! That hurt!"

"Really?" Bon pulled it again.

"Hey!" Rin growled.

Bon smirked and tugged Rin's tail harshly.

"Are you sadistic or something?! Stop it!"

"Aw, I'm sorry." Bon said with fake sympathy, stroking Rin's tail gently.

Rin's face turned a bright red, he grabbed Bon's hands and tried to pry his finger away, "S-stop...!" Rin gasped quietly.

"What was that?" Bon teased.

"Stop...!" Rin said a little louder, panting softly now.

"What if I don't want to?" Bona sked, raising an eyebrow.

Rin growled, but it was cut off by a loud moan as Bon rubbed the tip of his tail.

"So you like it when I do this?" Bon mused with a smirk.

"S-shut up!"

Bon admitted to having a slight crush on Rin, with the way Rin was just so stupid and naive, and then there was this. Bon had complete control over Rin and he loved Rin's reactions to the way he palyed with his tail. He pressed his lips against Rin's gently, then wrapped his arms around Rin's waist.

Rin's eyes widened, but soon he relaxed in Bon's arms and kissed back, wrapping his arms around Bon's neck.

Bon licked Rin's lips asking for entrance, and, of course, Rin let him and their tongues battled for dominance. Naturally Bon was the winner.

Bon broke the kiss then sat down and pulled Rin into his lap. He kissed along Rin's jawline and down his neck, while he unbuttoned Rin's shirt.

Rin moaned and dug his claws into Bon's shoulders. He hissed and pulled Rin's shirt off, then sank his teeth into Rin's shoulder.

Rin groaned as he fumbled with the buttons on Bon's shirt, desperately wanting him to take it off.

Bon chuckled and pulled away from Rin to finish what Rin started, then pulled off and threw it on the floor. Then Rin crashed his lips against Bon's. He wrapped his arms around Bon's neck, and Bon placed his hands on Rin's hips.

There was a clicking sound as the door to the room was unlocked, but Rin and Bon didn't notice, and they didn't notice as Yukio opened the door to find them practically eating each other's faces. Yukio dropped his gun, which he was just about to put away, and it clattered onto the floor.

Rin and Bon froze.

"Nii-san..."

EDIT*20/06/2019

I have one question. Just one.

What the fuck? This fic- I- it was downright unreadable. It was just one giant block of text, with no actual paragraphing AND THE SPELLING MISTAKES, the amount of spelling mistakes in this tiny little fic. I'm in physical tears right now, I cannot comprehend the fact that people in the past READ THIS and ENJOYED IT. But I mean, I guess I have to thank you guys, because without you, I may not be where I am now. And where I am now is writing much better fanfics.

I'm almost tempted to rewrite this, just to see how far I've come in 6 years, would have to brush up on my Blue Exorcist lore though-
