It started right after they found out Rin was the son of Satan.

Suguro couldn't believe he'd been fooled for so long. He couldn't stop staring at his half-demon classmate after that–or rather, the demonic teen's features.

He had small fangs that were impossible to miss now that he knew they were there. They didn't look very dangerous, but Suguro knew they were razor sharp and could easily pierce skin if needed. Plus, they lengthened and became more prominent when Rin unsheathed his sword.

His ears were pointed, but still short unless he was in his released form. Suguro wondered if they were sensitive to the touch. He knew Rin's senses were all heightened and that Rin could hear conversations across the large cram classroom.

Rin's tail was long and sleek, the same color as his hair. It was kind of like a cat's, but with a soft tuft of curls at the end, also matching the teen's hair. It usually had a mind of it's own and seemed to be hard-wired to Rin's emotions, but he had some semblance of control over it. Suguro had seen Rin pick things up or hold people back with the appendage before, which also meant it was stronger than it appeared. He'd been able to pull Suguro back by his arm with the tail once when the older boy was about to be stupid and charge into a nest of demons with only a bozooka and fatal verses.

"I can totally respect you charging in there like a badass, but I can't respect it if you die." Rin had laughed.

God, that crooked grin. If Suguro stared at the half- demon's features, he'd definitely notice how attractive Rin was as well, even with the demonic looks. He could either look hotter than the pits of hell or incredibly cute at times and it was infuriating. How could he possibly pull both of those off and not even bat an eye?! Even more, Rin himself didn't think he was good-looking or a good person. It made Suguro wanna shake him until he realized how amazing he was.

In his released form, Rin looked more like a demon. Long pointed ears, longer and messier hair, elongated fangs, and spectral blue flames surrounding him. He was terrifyingly beautiful. Captivating.

Suguro sighed and finished taking down notes for the next class tomorrow. He needed to concentrate.

§~•~§~•~§

Suguro would never in a million years have expected Rin to make a move on him. Hell, he didn't even think the idiot realized how many people wanted him. Usually, the half-demon tended to be completely oblivious to a lot of things. Especially things like crushes. It was obvious Moriyama was crushing on Rin hard even though she'd already friendzoned him. It seemed Rin had at least listened and figured being friends was better than awkwardly ignoring each other forever.

But what Rin did to him in that corner....Suguro honestly should've figured out the teen's plan after all that teasing....

§~•~§~•~§

The team was going to get mochi after a successful mission and Rin chose to sit by Suguro. He always sat by Suguro, who happened to sit the farthest away from Yukio. The teen thought Rin just didn't want to be around his brother. The two didn't seem to like each other that much, so he couldn't blame Rin.

They all ordered and made small talk while they waited for their food. When it arrived, the only noises were the quiet conversations around them from other people while they ate. Comfortable silence was something Suguro cherished.

As he enjoyed his red bean mochi, Suguro felt the softest touch on his arm. He glanced at Rin, who was eating his own mochi. The teen dismissed it and kept eating.

A minute later, another caress-this time on his thigh. It was on the other side of Suguro, but he knew that tail was long enough to easily reach around him. This time, he discreetly raised an eyebrow at Rin. Still no reaction, just the shorter teen enjoying his mochi. He narrowed his eyes, but decided to drop it.

The third time, the tail actually went under his shirt to brush against his side and he flinched just slightly. This time, he turned to glare at Rin who was still just eating his mochi. Then, the half-demon smiled into his mochi and fucking winked at Suguro before going back to eating his food like nothing happened.

§~•~§~•~§

"Well, at least we know you're good at something." Suguro shouted angrily over the wind. It was just him and Rin alone on a mission and they'd pissed off some kind of fire demon, which was why they were running.

"Now is not the time to be listing my skills and flaws, Suguro!" Rin growled, ahead of him like always.

"Hey, don't leave me behind!" The taller male snapped. Rin laughed and dropped back just enough for him to hear. "It's not my fault you run as fast as a slug!"

A few more minutes if running and Suguro's dude began to cramp.

"Alright, I've got a plan." Rin said. At Suguro's groan, he pouted.

"Hey, do you have any suggestions?!" He demanded.

"No, sadly. What's the plan?" Suguro panted. He was getting tired and his side hurt.

"I can swing up into one of these trees easily. That thing won't be able to see where I went since we're ahead of it. You slow down and when it gets close, circle around my tree. I'll attack it from above."

"I'm the bait?!" Suguro cried.

"Yes, just suck it up already and do it! Ready? Go!" Rin sped up and then leaped straight into one of the tall trees around them without even waiting for an answer. Suguro silently cursed him as he obediently slowed down.

He circled around the tree and heard a deep growl that nearly shocked his soul out of his body as Rin dropped down onto the demon and stabbed his sword into it's back. Rin was capable of making purely animalistic(or demonic, Suguro supposed)sounds and it always made Suguro shudder. In a good way or bad way, he could never tell.

When the demon's flames tried to fight Rin's assault with its own flames, Rin overpowered them with his until it all that was left was a smoking carcass. Rin let out a sigh of relief and grinned down at Suguro from atop the corpse.

"Great, now get down!" Suguro called up to his friend. Rin huffed and sat down hard.

"Fuck that, I'm tired." He replied, falling onto his back.

"Oh, come on. We have to report back to your brother soon or he'll hunt us down and probably punish us when he realizes we've been done for a while." The older teen argued. "And I am not cleaning and organizing another supply closet that hasn't been opened since the 70's!"

He heard Rin groan and then rustling.

And then he was on the ground. Rin was on top of him–it had to be on purpose, Suguro had seen him stick landings from higher up. Frowning, he flipped them over. Rin stared up at him, pleasantly surprised, before his expression turned mischievous and Suguro just knew he was going to say something cheeky.

"Well, geez, Suguro. At least take a guy out to dinner first." Rin snickered. His tail wrapped around the taller teen's thigh and Suguro ignored the burning in his cheeks as he stood up. Rin simply grabbed his hand and pulled himself up. As they walked back, there was comfortable silence between them. Yukio looked annoyed but at least not pissed when they showed up ruffled and covered in dirt and leaves, past their time limit.

§~•~§~•~§

Suguro was about to take another bite of his rice when hands covered his eyes. He was surprised at first, but then he remembered that most people didn't have calloused hands or a body temperature this high.

"Okumura?" He guessed.

"Aww, too easy!" Rin complained and plopped down next to him. Shima and Konekomeru were in the library getting reference books for a report due at the end of the week. It was kind of weird that Shima had gone too, though. He usually slacked off and passed with a C.

"And how many times have I told you to just call me Rin?" The demon boy scolded him.

"Why do you insist on me calling you by your first name? And only me?" Suguro shot back. "Because you're the only only one who actually makes an effort to be a good friend." The half-demon answered honestly. "Everyone else is too busy for me now. You and Shiemi are kinda all I have."

Rather than seeming sad about that like Suguro thought he would, Run sounded like he was okay with it.

'He's used to this kind of thing....' Suguro realized.

Rin reached into Suguro's bento and took a piece of chicken with his fingers. He popped it into his mouth and hummed happily. Sometimes the older teen forgot that Rin always at his own food and never really got anything from the student store or the lunch menus. They were either too expensive or too artificial for him to enjoy.

"Oh, so you just mooch off of me when I get the good food? You brat." Suguro said jokingly, swatting at Rin's head lightly. Rin gave a grin.

"At least someone in those kitchens can cook right." He said as an answer. He went to grab another piece, but Suguro slapped his hand.

"Ow!" Rin pouted next to him. Suguro rolled his eyes and gave in.

"Have some manners, you're still half-human. Here." He offered Rin a piece with his chopsticks. Rin ate the food gratefully, his tail swaying contentedly behind them.

§~•~§~•~§

And finally, that day....

It was after class. Rin had apparently given up on the school uniform and just wore his regular clothes to school. The teachers were too scared to dress code him because he was the Headmaster's charge(Suguro suspected Rin himself had let that get out so he could take advantage of it, but there was no proof)and Cram School teachers didn't care as long as you could fight in the clothes you were wearing.

The Son of Satan was wearing a white mucle shirt and a black leather jacket with spikes on the shoulders. His pants were black with the usual chain hanging on the side. He had his fingerless gloves and trademark red boots on with Kurikara on his belt around his waist. He'd seemingly gotten tired if pulling it from a Ross his back.

Over the course of training that day, Rin had stripped a few items off and lent them to his classmates.

First, Shiemi had said she was cold, so Rin gave her his jacket. Then, Shima complained about how his staff chaffed his hands, so Rin gave him his gloves. Then, they'd fought a demon and Rin ended up piggybacking it. He yanked his chain free from his belt loops to strangle the beast and that was when the rest of his classmates found out that his chain was made from holy metal.

By now, all he had was his stained and ripped white shirt, ripped pants, dirty boots, and his sword.

And hot damn, he was gorgeous all ruffled up like that. Suguro had only ever seen him in a uniform. Now, he got a clear view of solid, flexing mucle underneath flawless, smooth skin as the teen practically threw the remaining demons into each other. He was absoloutely chaotic, but somehow, he was still beautiful.

Suguro pushed those thoughts aside. They headed back to the classroom to get their things and turn in for the night. Suguro was walking down the hallway when he was spun around and suddenly, unexpectedly soft lips were on his. He barely registered a tail before realizing it was Rin pushing him into the dark corner of the hallway.

He thought of resisting, but decided that he liked this and gave in to the half- demon. Even though Rin was shorter than Suguro, he was stronger and tougher, so the half-demon was pretty much dominating him. Suguro opened his mouth with a moan, shamelessly enjoying how rough Rin was being with him.

Their tongues slid against each other languidly. Heat rushed over Suguro's body as goosebumps broke out across his skin and his heart beat so hard, he was sure Rin could feel it through his chest. A shudder made its way down his spine.

They separated to breathe, warm breath on each other's faces. Rin grinned–a nearly feral look, filled with so much heat, but also barely concealed happiness–and Suguro leaned in to kiss him again.

This time, they went slower. It was a softer, sweeter version of the first one. Suguro let his tongue wander over the small fangs and Rin pressed him harder into the corner.

Something Suguro had never realized was that Rin smelled like different kitchen spices–mostly cinnamon and nutmeg, some cloves. It was pleasant and honey and purely Rin. 

He loved it. He loved how Rin smelled, how he tasted, how he fit perfectly against Suguro's own body.

And that was how Suguro's first and second kisses went.

DEMONSDEMONSDEMONSDEMONSDEMONSDEMONS

Hey guys! This is only the first chapter. Welcome to The Twins Thirsting After Bon's Ass™. There's probably only going to be three chapters. I published this as a Valentine's Day special, but it won't be finished on Valentine's day because highschool is a bitch.

Edit 7/1/21: I'm editing this story, but I'm really glad that it was already thankfully pretty good, just need to make a few adjustments to make the words flow better. I'm so thankful it's not super cringy like some of my older stories that I used to be so proud of. 😫

I agree with you get me, Highschool was a bitch. But I just graduated, so ha! I have no friends left except the one who's always been there and lives across the country, but that's okay. I can probably find much better friends in college than I did in high school after that whole fiasco. 😅
