A/N Did I say this was a one-shot? Oh well, I had this idea bouncing around after I finished writing Incandescence and originally I thought it might turn into a whole nother fic. But it fit neatly into this AU so I thought, what the hey, I'll just add another chapter. Also, if the timeline doesn't quite match up to canon, just assume it's because Mephisto was jumping all over the place through time (like his "talk" with Amaimon I put in the first chapter happens a little later in canon) and things play out the same, just in a different order. Boy it sure is great having a literal time demon to cover up the fact that I can't keep a timeline straight :D
"Amaimon has decided he likes Rin after-all. Rin wants to know when HIS feelings are gonna be taken into account." Cue Amaimon following Rin around being a curious (read: nosy) pest while Rin tries to get through exams, complete Mephisto's tests, and prepare for the festival without his fellow exorcists and twin combusting over their new tagalong."
Uh did I say I was gonna update Retrospective Days next? I meant I was gonna add another chapter to this instead :DDD
(I promise I'm working on RD too)
Also, I thought I'd put down some thoughts about the Rin/Amaimon/Mephisto pairing (or any combo thereof). In my head-canon, the demon kings are more like a pantheon of gods a la ancient Egypt, Roman, Norse and Greek deities are portrayed and less like biological siblings like Rin and Yukio are. So, much like all the Norse gods came from Ymir, all the demon kings came from Satan.
SPOILERS for the newest aoe chapters revealed that the body Amaimon is possessing is literally a clone of Mephisto but that they all started as concepts that gained egos and eventually bodies whereas Rin and Yukio are born from Yuri Egin (human) and Satan possessing a clone body (I think, don't quote me on this). So, I don't really consider this a sibling pairing fic like a Rin/Yukio fic would be, more clonecest, if anything. And they're all immortal demons so what's age even mean? :}
And that's my TEDtalk.
'This is how I die.'
Rin wanted to sink into the ground and never come up.
Not because he was depressed or anything, although with the way his life was right now that could always change, but because the embarrassment was eating him alive.
Three days. Three days had gone by since the… incident with two demons who shall not be named.
Every time he thought he was close to forgetting, some small thing would remind him and he'd become a blushing incoherent mess, needing to hide somewhere he could calm his racing pulse.
Like now, when his tail had cramped up from being wound around his waist and he'd reached up his shirt to massage the pain away only to be brought back to the night Amaimon had run delicate claws over it while Mephisto sucked the furred end and-
Oh god he was doing it again.
Rin let his head thunk down against the desk in his dorm, groaning at the unfairness of it all. Normally he'd be flinging himself into a cold shower to get over the feelings he definitely didn't want to feel or… taking care of the problem the old-fashioned way, trying not to think about any specific faces while he relieved himself. But, Yukio was coming home soon, and he did not need his younger brother walking in on- that- which was the crux of his current predicament.
Plus, there was the fact that for the past three days he'd been being stalked by Amaimon.
The bastard had taken to popping up on the edge of his senses and Rin could practically- feel- the intense stare coming from somewhere nearby. The damn demon had been leaving traces of himself all over town, either his scent or various dropped candy wrappers and food that Rin- knew- had to belong to the earth king.
He'd avoided Mephisto at all costs after the one time he'd seen him around campus.
Just catching a glimpse of the principal had transported his mind to that bedroom all over again and he'd squeaked and run the other way.
It especially didn't help that Rin had been fantasizing increasingly dirty scenarios every time he drifted off. He kept seeing the way Mephisto had claimed Amaimon's mouth, leaning over the smaller demon on the bed while Amaimon had just let him, slim green tail twitching over his hips.
So, Rin sat at his desk consumed with his thoughts and becoming increasingly uncomfortable until the sound of the door latch clicking made him gasp in relief. He jolted upwards, keeping his expression bright and cheerful and hoping Yukio wouldn't guess at where his mind had just been.
"You look like you've got a problem, Rin Okumura."
"Gah!"
Rin shrieked as he realized the person at the door wasn't Yukio, or even a person, really, pushing back into his chair and hearing it screech across the floor until he was stopped by the leg of his desk.
"Amaimon!"
The demon king of earth stood casually against the open door, face in his usual impassive expression and sucking one of the many suckers he always seemed to have. Except Rin knew the bastard had to be hiding a smirk by the glint in his gold eyes and the cocky way he'd said his name.
"Oh?" Amaimon came closer, shutting the door, "you remember my name, finally?"
Rin gulped, knowing there was a catch somewhere in that question.
Sure enough, Amaimon curled his lips in a smirk around the sucker in his mouth, jagged fangs revealed, "It's a pity, I was going to teach it to you again."
'He can't mean?'
Rin's eyes widened and his breath caught, face blazing red.
"No way! I thought I told you bastards to leave me alone!" Rin yelped, crossing his hands in an 'X' in front of him to ward off the advancing demon.
"Hmm?" Amaimon stopped, hand on his hip as he considered the half-demon from a few feet away, "why are you resisting? Didn't we cover this already?"
"What?" Rin said, trying to figure out what the other could be talking about, "cover what already? You can't just barge in here and expect me to do that stuff with you without warning!"
"Ah!" Amaimon exclaimed, dropping his fist into his palm, "I remember. You told me you wanted me to ask you beforehand if we could play together."
"Yeah, that's it," Rin nodded, crossing his arms and nodding.
Wait…
"No, that's not what I meant!" Rin said, frantic as he realized that Amaimon had been recalling their conversation about play and how he'd totally misconstrued what demons considered it to be. Or rather, he hadn't realized they had two definitions for the word and didn't distinguish them very well.
"Rin."
And then Amaimon was on him, knee wedged between his thighs on the edge of the seat and hands on the desk, bracketing him in with nowhere to go
"Can we play now?"
Rin's breath stuttered to a halt, noticing then how close Amaimon was to him and feeling the heat of his body right through his clothes.
Amaimon's slit-pupiled eyes seemed to have a hypnotizing effect on Rin, pinning him in place with a heavy-lidded look like a mouse staring up at a snake.
"I don't-" Run took a shuddering breath as he tried to formulate an argument. Something, something, there had to be- something- or he was going to be in a real awkward position when Yukio-
That's it!
"My brother's gonna be home soon! He'll kill us if he sees you here!"
Saved by the brother card, Rin sighed internally, adrenaline pounding through him at the close call.
"Then we'll just have to make this quick, won't we?" Amaimon grinned like a shark, taking his sucker out of his mouth and tossing it behind him to a random corner of the room.
Before he could protest, Amaimon was sliding onto Rin's lap, bringing his hand up to grip his hair and slipping his long, tapered tongue into his mouth.
"Mmf!"
Rin was overwhelmed by the sweet taste of cherries from the lingering flavor of the sucker and Amaimon's slick tongue winding against his.
He sighed into Amaimon's mouth, hands coming up to grip at the other's shoulders and feeling his eyes shuttering closed without meaning too.
This may or may not have been one of the many scenarios he'd been fantasizing about.
He couldn't help it! Rin moaned as Amaimon pulled him flush to his chest, trembling at the friction of clothes against skin.
Before that night with the two demons, the most action he'd gotten was himself, the shoujo romance books he hid under his bed, and the vague idea that he'd like to kiss Shiemi maybe someday.
Now, all he could think about was claws tracing down his hips, toying with his tail, while another pair of hands pulled at his hair and bared his neck to sharp fangs and a hot tongue.
Amaimon seemed to know where his mind was, having moved on from his mouth to nibble down his neck, each small nip sending electricity shooting south until Rin was writhing against the body above his.
The bold demon had already loosened Rin's tie and began unbuttoning his shirt to reveal his wound-up tail, which was shaking, though whether in anticipation or fear, Rin couldn't tell.
"Have you learned to keep your tail to yourself then?"
Rin blinked hazy eyes as he tried to register what Amaimon could possibly be talking about.
"You certainly haven't in that school of yours," Amaimon said against the point of his tail near his collarbone, heated breath teasing the furred-skin and leaving Rin feeling weak.
"When have I what?" Rin couldn't remember when he'd shown his tail in school, too focused on the sharp fangs within biting distance of the sensitive appendage.
Amaimon placed a soft kiss to the tail, sending heat straight to Rin's stomach, his muscles tensing in an effort to control himself.
"You brought it out to threaten that weak apparition bothering that human classmate of yours," Amaimon watched him, keeping his mouth within centimeters of Rin's tail so that every movement of his lips caused them to brush the short fur and sending waves of sensation through him.
"And then you brought it out again to show him to his face that you were a demon," Amaimon cocked his head, settling his hands on Rin's hips and gripping them tightly, "I almost came out to play with you right there in front of all your classmates and those miserable exorcists at your shameless display."
Rin would have liked to protest that ridiculous possessive statement except that Amaimon chose that moment to grind his hips down on Rin's.
"Ah!"
Rin's head fell back on the chair, mouth gaping at the delicious pressure Amaimon was applying.
His pants were unbearably tight now, and every movement of Amaimon's hips brought a mixture of pain and pleasure that prevented him from thinking past the next moment.
Amaimon appeared to have an actual plan, however, the earth king reaching down to undo both their pants.
Rin was helpless to do anything but watch as Amaimon stood long enough to free himself before returning to tug Rin out of his boxers and sit back on his lap.
Seeing himself lined up against Amaimon was almost too much to take and Rin let out a thin whine.
The noise attracted Amaimon's attention right away.
"That's a strange sound. Make it again."
"No way," Rin growled out, cheeks flushing and trying to keep silent in embarrassment at the sound he didn't even know he could make
"Oh?" Amaimon's eyes seemed to glow with an unholy light, "I'll just have to get you to make other fun sounds, then."
A soft click reached both their senses, then.
Rin had a brief moment of confusion before he realized that click had come from the vicinity of the front door a few floors down.
"Oh god, Yukio's home," Rin yelped, hands trying to push Amaimon off as the panic hit his nerves.
Amaimon didn't acknowledge the impending doom heading towards the room, "I guess we'll have to finish this quickly then before he reaches us."
"What?"
Rin moaned, the sound escaping his mouth without his say as Amaimon gripped both their lengths in his hand and began to pump them together, using the pre-come that had been collecting there as slick.
"Better keep quiet, don't want that human hearing you all the way downstairs," Amaimon teased, voice breathless but no less sly.
There would be no coming back from the embarrassment, Rin knew, bringing his hand up to fist over his mouth to try to muffle the sounds he was making at each pass of Amaimon's clever hand.
His other hand seemed to reach out of its own accord to grip Amaimon's shoulder, needing something to hold onto while he came apart.
Amaimon ran a clawed thumb over Rin's and his slits with his free hand and Rin couldn't hide the groan that left his mouth when the demon brought it to his own lips, tasting.
Rin found his hand pulled away and his mouth captured and he could suddenly taste himself mixed with the earth king on his tongue.
He was so close, body trembling and heat coiling in his stomach. His tail clenched around his torso, rubbing against the skin there with a mind of its own.
Amaimon released his hand and parted his shirt further, reaching around to the base of his tail and giving a hard tug.
Rin keened, clenching his eyes shut and coming against his own chest.
Amaimon gave a few more pulls and soon was adding his own come to the mess.
Rin wasn't given any time to relax, finding the other demon already moving off his lap to crouch at his knees.
Then there was a warm mouth on his over-sensitive skin and Rin cried out, bewildered.
He didn't have any time to consider it before the earth king was bringing his lips to Rin's chest and mouthing the skin there too.
He stared down at the green head at his lap. Amaimon was cleaning him off, licking all traces of their activities away with broad sweeps of his tongue.
Rin watched with glazed eyes, knowing this scene before him was going to be featuring heavily in his future fantasies.
He found himself being tucked back into his pants and his shirt buttoned up, feeling like he was having an out of body experience.
Amaimon began re-doing his tie with brisk, no-nonsense movements. He tugged it into place, pulling Rin up and kissing him at the same time.
"Mmf!"
Rin gasped at the sudden kiss, shocked out of his stupor as the past half hour caught up to him.
He heard steps down the hall and broke this kiss, "oh my god, go! He's almost here!"
Amaimon smirked, pulling Rin up against his chest and placing a chaste kiss on his head.
"Let's play again soon, Rin."
Then the absolute bastard was at his window, opening the shutters and hopping out without a backwards glance.
He didn't have any time to curse out the demon as the door was opened and Yukio entered the room.
'Act normal, act normal!'
Rin turned and grinned with grit teeth, waving at his twin, "Hey, Yukio, long-time-no-see. How was your trip?"
Instead of answering him, Yukio looked around the room with furrowed brows, "does it smell…musty in here, Rin?"
'Oh god, he knows,' Rin felt his grin grow brittle and his heart thunder through his veins as he tried to think of a way to explain to his younger brother that he was smelling the scent of sex in the room because Rin had just been taken advantage of by the demon king of earth and oh, yeah, that wasn't the first time and he definitely hadn't tried to fight him off this go round either.
"Well, we should probably clean in here," Yukio shrugged, unknowingly sparing himself the sordid details, "why don't you open the rest of these windows and we'll deal with this when we get back from remedial classes tonight."
"Oh yeah, sure. Good idea," Rin sighed in relief, feeling semi-hysterical giggles threatening to escape. Luckily, he kept it together long enough to grab Kurikara and his class supplies, heading to the door in the hopes of getting away from the scene of the crime before Yukio noticed anything else suspicious.
"Hold on, what's this?"
'I'm dead.' Rin gulped and looked around to see what damning evidence Yukio must have found.
"Rin, what have I told you about leaving your junk food around the room, why would you just toss this in the corner like that?"
Yukio held Amaimon's sucker between pinched fingers in disgust, unable to imagine why Rin would leave an unfinished piece of sticky candy to melt into the wooden floors. Didn't his brother know that's how you got ants?
"I was gonna finish that!" Rin yelped, grabbing the sucker out of his brother's hands and sticking it in his mouth before he could think.
"Ew, Rin, why would you do that?"
Yukio grimaced, shuddering at the germs that must be all over that sucker.
'Because it was evidence of the dirty, dirty deed that was done in this room,' Rin thought wildly, tonguing the cherry sucker and tasting the hint of Amaimon still on it.
"Er, I don't like wasting food?"
Yukio shook his head at his twin's weird behavior but didn't question it further, heading out the door into the hallway.
Rin dragged his tongue over the sucker and followed Yukio, trying and failing to get his mind off of Amaimon.
He really hoped the remedial class was something distracting.
Poor Rin ;)
Thanks for reading. Let me know what you guys thought!
