Chapter Text
Touya didn't come back that night, nor the one after. They'd spent longer periods of time with no contact before but something felt more definitive about this one, like the axe of an executioner coming down. Keigo was so furious at Touya for leaving without an explanation, for not giving Keigo a chance to understand what had happened. To realise that he knew nothing of his friend of a decade. That he'd probably been the only one to think of what they shared as a friendship.
Every smile Touya had sent his way, every meal Touya had prepared for him, every time Touya had let him cry on his shoulder...
All fucking lies, and Keigo hated him so, so much, although maybe not as much as he hated himself for falling for it. God, he was so stupid. First person to ever show him kindness in his life, of course Keigo had been immediately smitten, rose-tinted glasses on.
He was such a fool.
The microwave chimed and Keigo painstakingly dragged his body from under the fake kotatsu to go pick up the popcorn. He didn't have any motivation to cook or order in, and he'd run out of cup ramen the day before.
He'd also forgotten again about the stupid laundry, which was the only reason he was wearing Touya's hoodie right now. Not at all because he was missing his stupid, lying friend. Roommate. Acquaintance. Dammit.
He wasn't going to cry. Not over someone who'd never cared anyway.
Keigo cleared his throat loudly and switched the TV to another channel he didn't bother watching either, before returning to his stack of drawings. That first one he'd scribbled on the back of a receipt as soon as he'd seen the demon the first time. The ones he'd made right after that, and then his other attempts, more recent. Trying to refine that first childish drawing, stupid looking and yet still good enough to attract the attention of established paranormal hunters - and established sponsors.
Beside them, the tattoo design Touya had completed for him.
Keigo started another sketch of the demon, the fine lines of the horns so similar to the ridges he'd felt under his hands - they'd been so warm. He would never have guessed that. Or was that because of the glamour? Who the fuck knew. Maybe it was just Keigo's clammy hands getting confused. He drew the hair - Touya's hair - white, and the eyes - Touya's eyes - blue, and the line of Touya's nose, and–
The pen stopped. Keigo took in a deep, shaky breath.
Then he went back and scratched furiously over his new sketch, covering it all in black hard enough to pierce the paper. The pen moved to another drawing after that and he did the same, and the next piece of paper was the tattoo design and... and Keigo stopped, exhaling with a sob. He'd started this piece himself. He'd talked about it with Touya, in so much detail. Touya had finished it for him and it looked beautiful. Most of it was on his back already.
So many of his dreams and hopes hid in those feathers.
So many of these lines reminded him of whispers in the dark, huddled close to Touya for warmth because he'd sneaked out of the dorm at night without his jacket.
Keigo traced the line of a wing with his finger.
He wasn't going to cry. He was too tired for that, all out of tears and constantly shifting between anger and shock.
Upset with himself for missing it. He'd been looking for the paranormal all his life and he hadn't even noticed it was right under his nose.
A sex demon, at that. And they hadn't even slept together! Was Keigo not good enough? Were his feelings in the way?
Then Keigo got upset with himself again for being sad that the sex demon had never slept with him despite their proximity... His head hurt from all the constant contradictions and grief.
Touya was lost to him forever now. Silly jokes, smiles and shared breakfasts... all of it in the past.
Keigo zipped Touya's hoodie up to his chin and forced himself to pay attention to the TV for a bit. He couldn't even tell if this was a movie or a food documentary. Or maybe the news? He squinted at the screen and tried to pay attention to the voices when the key turned in the front door.
His heart did its best to pound right out of his chest and for a moment all Keigo could hear was static ringing in his ears.
From the corner of his eyes, he saw Touya step in, more hesitant than ever. Instead of vindication, all Keigo felt was pain at remembering Touya's quiet thanks for giving him a home when they had first moved in.
Keigo kept on staring blankly at the TV with all his strength, like he would die if he looked away.
"Kei?" Touya tried, removing his shoes before walking closer.
At this point, Keigo couldn't have told what was on the screen even if his life depended on it, no matter how hard he was staring. Voices sometimes pierced through the fog in his brain but all of his attention, all of his body, all of his existence was turned toward Touya.
Touya dropped his jacket on the couch and knelt beside it before picking up the remote to mute the TV.
"Keigo, please. Look at me."
Stilted, Keigo turned his head toward Touya. No horns in sight, as if it had all been a dream except now Keigo couldn't help but wonder about the mesmerising gleam at the back of Touya's eyes. No matter how sad and sorry Touya looked right now, his eyes still seemed to glow.
"I missed you," Touya said, sounding so sad, like he didn't expect Keigo to believe him.
It's only been two days, Keigo wanted to reply, but the last two days had felt particularly long and miserable and only a sob left his lips, so he forced his mouth closed.
"Kei," Touya said, sounding broken.
"Are you putting some kind of spell on me?" Keigo asked. He wanted to throw his arms around Touya's neck and sob his heart out against his chest but he didn't know. Was that him? It felt like him but he had known Touya for so long. What if the spell ran deep?
"What? No! I'm... I'm not that kind of demon."
"Show me," Keigo demanded.
Touya seemed to hesitate. "Are you sure?"
"Please. I'm Hawks."
The air shifted. Horns flickered into sight just as night dark hair gave way to spotless white, starting from the roots and stopping right before the tips, leaving them black. Ink patterns bloomed like flowers under Touya's eyes and on his jaw, reaching up to his ears before moving down his neck. Behind Touya, a long tail also materialised, endless and agile.
Exactly like the demon of Keigo's childhood.
Fuck.
Touya really was the demon Keigo had seen as a child. His drawing had been rough but all of the salient points were there. It hadn't been a dream.
"Can I touch them?" Keigo asked, hand already approaching and hovering near a horn, entranced.
When he glanced down to check if it was okay, Touya looked crestfallen and utterly miserable. That kind of look didn't belong on his face.
Keigo's hand fell back on his lap.
"What's wrong?"
"I really missed you, Kei," Touya whispered. "If there's any way you'll still have me... I'd like to be around you, in some way, any way you'll accept. I don't– I don't want to lose you."
"Tou," Kei said, surprised. "I've had a crush on you for as long as I can remember. I don't know if it's some kind of spell from you, but..." Keigo swallowed. "It's awful without you around."
Touya's eyes widened. "I'm not lying to you about this. I have... some way to make things feel even better when I'm sleeping with someone, but it only works when we're both turned on, and only while we're having sex. It makes the... transfer of energy easier? It's kind of how I refill."
For a second, Keigo felt desperate to know more and quiz him about it. Then his mind went into overdrive picturing all of this in too much detail, imagining Touya's low voice combined with the groans and moans he'd heard, searing relief overshadowing the miserable exhaustion of the last few days.
"Oh?" Keigo asked, trying for a joke. His emotions were all over the place and he couldn't tell if he was going to cry or scream or laugh hysterically next. "So you can't tell if I'm turned on, right now?"
Touya's pupils immediately dilated and a flush of heat spread through Keigo. The pent up desire from months of wet dreams suddenly seemed ready to burst.
"Don't play with me, Kei. I've been smelling you for months now..."
Touya's gestures grew more agitated, and he leaned forward as if he could smell him now...
"And I've been hearing you..." Keigo countered.
He couldn't help leaning closer either, he missed Touya's warmth so damn much.
"...and jerking off to me, I could tell..."
"Touya–," Keigo gasped, uncertain about what he wanted. Actually, no. He knew. "Touya, of course I want you to stay..."
He didn't know how to express all of the ways in which he meant this, all the feelings and longing and yearning behind the words.
Fortunately, he didn't need to.
He couldn't have told which of them moved first as they held each other, but neither of them would have lost in a contest of who was gripping the tightest.
It was like a dam breaking, a torrent of emotions crashing through him. Touya's strength and scent surrounded him when he'd thought he would never get to see or feel him that close, again, ah...
And Touya's neck was right here, just under his nose.
Keigo bit it, hard. Touya's answering moan went straight between his legs.
"Keigo, what the hell?"
"This is for lying to me for so long," he said viciously, a string of saliva still connecting him to Touya's neck before he bit down again, right under the other teeth mark. Touya's skin tasted like the ocean on a warm day, and he could feel himself getting addicted already as he pulled it between his teeth.
Not like a weak human bite would endanger a big bad demon anyway, right?
Touya just gripped his sides tighter, his breath shaky when it brushed against Keigo's hair.
"K-Keigo, if you mean this to be a punishment, it's really... not having the effect you want."
Touya shifted. His tented crotch brushed against Keigo's knee and sent a jolt up his spine.
He hadn't expected anything like this, but he couldn't deny this was something he'd wanted. He gulped slowly, torn between wanting to be a little mean and the reality of seeing his marks on Touya...
...his marks...
His excitement only grew.
"Should I stop?" he breathed out, enjoying the shivers on Touya's skin but still pulling back to see his face.
"Only if you want to," Touya exhaled, his eyes a tiny blue ring around black pupils blown wide.
Keigo held his breath.
Then he leapt forward and yanked Touya's shirt down, biting fully into his shoulder. The moan Touya let out had Keigo panting through his teeth, unwilling to let go but turned on beyond belief.
"Keigo, are you sure you know what you're doing, because once I get a taste of you I don't think I will ever let you go–"
"Perfect," Keigo hissed, finally releasing his prize to answer.
In the next blink, Touya pulled him from under the table and threw him over the couch. Then he ripped Keigo's sweatpants off. Fuck. The unfair strength that had been there all along... With a movement that had no right to be so graceful, Touya removed his black t-shirt and dropped it to the floor before advancing on Keigo and gently pushing him back against the armrest.
Touya hummed as he unzipped Keigo's hoodie - his hoodie that Keigo was still wearing - and groped his chest appreciatively. His hands were warm, his grip firm. Everything in his expression screamed awe and admiration.
Then Touya leaned forward to suck hickeys into his pecs while Keigo arched and bent under him, also trying to reach as many places as he could with his lips and teeth. Time blurred, Keigo hungry and grateful for this chance to finally stake his own claim on Touya, something he hadn't realised he hungered for, and increasingly turned on by Touya's matching desire.
"Touya," Keigo whimpered as unbearable waves of need crashed through him.
Eyes half-lidded, Touya stopped to look at him, attention fully focused on Keigo's body while the horns started to flicker out of sight.
"Keep the horns on," Keigo said hastily. "Hm. If, huh, you don't mind."
"Yeah? You like them?" The smirk on his face... Damn him. "I can keep them visible. It's just been some time since I could let them out while doing this..."
As he said that, he pulled Keigo's legs onto his shoulders, shoving the plushie or whatever cushion was there under Keigo's hips to lift him up. Keigo had never felt so exposed nor so turned on, especially as Touya's mouth approached his dripping cunt to, to fucking inhale the scent of his excitement.
"Fuck, Keigo," he whined, so near.
The air teased his folds and caused shivers to run up Keigo's spine. One of Touya's arms snaked around Keigo's thighs to open them wider and Keigo gulped before remembering Touya's reaction when he first grabbed a horn. So he did it again, wrapping his palm around it and making sure to meet Touya's eyes as he spoke.
"Yeah. I like the horns."
Touya flushed down to his chest and all reason seemed to leave his darkened gaze for a second. He surged forward before stopping again, licking his lips, so tantalisingly close and yet still doing nothing. Head on the armrest, ass up and legs on Touya's shoulders, Keigo couldn't do much except wait for Touya to just get on with it already.
"Touya," he whined, pulling on the horn lightly.
"I don't usually mention it," Touya started, voice shaking with desire, "but people don't usually know I'm a demon either. My saliva kind of acts as an aphrodisiac... Are you okay with this? It only works if people are already excited, but... well."
Instead of finishing his sentence like a civilised person, Touya just plunged two fingers into Keigo, sliding into the slick entrance without any difficulty before pulling them out again, glistening.
"Oh my god, would you just stop talking?" Keigo screeched, embarrassed and yet still massively turned on. "I can't possibly get any more horny than I am right now. Just get on with it!"
"I've been dying to get a taste," Touya exhaled. "Hold on."
Touya gave him a long lick and Keigo clenched against nothing, throwing his head back. Fire rushed through him, the excitement burning up and down his spine so brightly he could feel it down to his toes.
"Fuck," Touya whimpered, as if he was the one about to lose his mind.
Touya strengthened his grip before diving back in, licking and pulling him open to expose him better and there was nothing Keigo could do except hold on. Sometimes, Touya's hand came down to grope his chest and flick his nipples, only heightening the ecstasy. Keigo just got wetter and wetter, and Touya just kept lapping it up as soon as he could reach it. With a trembling hand, Keigo used the hoodie to wipe the drool dripping off the corner of his lips, then he decided to bite onto it to swallow his moans, afraid he sounded too slutty.
But this all felt so good!
Faintly, Keigo heard a zipper opening and he glanced down, only to see Touya pull out his cock, and oh my god, fuck. His cock was huge, and pierced, and Keigo wanted it so badly. He bit harder on the hoodie, clenching and thinking of nothing except want, want, want while Touya dug his nails in and bit into his thigh to warn him to stay in place. Touya sucked hickeys into the crook of his leg, not where Keigo wanted his mouth but still so hot as he growled words like mine and I want to taste you so bad before returning his attention to Keigo's drenched folds, slipping two fingers in right along his tongue.
Keigo could only take so much even if he also wanted more, more, more, everything was already so much and it better never stop... He was shaking and arching, barely able to move but so into it, and it only took a few gentle curls of Touya's fingers to send him over the edge.
Touya didn't stop, licking him and massaging his walls through the orgasm while doing his best to push him right into another one. Even when his tongue moved away so he could lick the juices trickling down his hand and wrist, keen not to miss a single drop of Keigo, his fingers kept at it and Keigo moaned hopelessly as his next orgasm built up, and up, and up and shattered through him. The hoodie fell out of his mouth as he threw his head back and closed his eyes, body tensing and pushing him deeper onto Touya's fingers. He couldn't have stopped the obscene sounds coming out of his mouth for anything in the world.
As Keigo slowly relaxed, his trembling body winding down, something hot spurt onto him. Panting, eyes nearly black with how his pupils swallowed the blue of his iris, Touya just stared at his cunt... His cunt that he had just come onto. Keigo clenched at the thought, like maybe he could swallow some of it inside if he tensed hard enough. Arousal started buzzing through him as the warm, thick cum wetly slid down his thigh and fell right onto the teddy bear.
The stupid, sexy smirk on Touya's face looked way too self-satisfied.
Pushing himself up on trembling hands and perhaps slightly annoyed, Keigo knelt up (and made the mess on the plush worse, but better not think about that) to push Touya back.
"I hope for your sake you can get it up again," he breathed out.
"Same to you," Touya said, still smirking but slightly breathless as well, eyes wide and looking unsteady.
Exhilaration written all over his face, he pulled Keigo on top of him and made him slide down onto his pierced cock - he hadn't even gone soft! The piercings were a new experience, brushing against Keigo's walls in astounding sensations that took a moment to adjust to. Keigo whimpered, blissfully overwhelmed, hopelessly trying to adjust his position when every little twitch and shift only caused a new devastating wave of pleasure to crash through him. He bit on Touya's shoulder to muffle his whimpering, hips desperately rutting against him with squelching noises.
It didn't take long for their movements to speed up. Touya's arms wrapped around his waist to both hold him where he wanted and to lift him up, right before driving him back down onto his cock and burying himself inside again, and again, and he could reach so deep. Keigo was seeing stars. Touya kissed his neck and shoulder, teeth grazing against his skin and...
"Wait," Touya said.
Head empty of anything that wasn't Touya and the pleasure crawling through him, Keigo took a few seconds to understand the words. He blinked slowly.
"W... What?"
"Your tattoos... they're shining."
Keigo stopped bouncing himself on Touya's cock to look over his shoulder.
"Are... tattoos supposed to do that?"
"They're infused with my magic..."
"What?"
"To protect you," Touya whispered as he traced a finger on a brightly shining feather.
"Why...?"
"If I'm not around to protect you anymore..."
A cold shiver broke through the hazy fog of pleasure Keigo had fallen into.
"What? Are you leaving?"
Touya didn't reply, staring at the radiant ink.
"No," he finally said, looking Keigo right in the eye. "Never."
Still connected, he pushed Keigo backwards and fucked him in earnest, in long and deep thrusts that seemed to touch everywhere while Keigo still tried to grasp what he'd just learned. These tattoos had a bit of Touya in them? On Keigo's skin and right under it?
"Ah!" Keigo let out a yell, already feeling the blurry pulse of an orgasm building up again.
If Touya had already marked him this deep... He wanted to brand him just the same. He tightened his arms around Touya's neck and nosed at his shoulder before biting again, deeper, to mark him as best and as far as he could. Touya stuttered above him before adjusting his hold so that he could slam his hips into Keigo even faster, pounding him into the couch. When Keigo had to stop biting to throw his head back and let his moans out, Touya closed the distance to fuck his mouth with his tongue just as good as he was splitting him with his cock, and Keigo could cry from the perfection of it all, just as another orgasm rippled through him.
Touya didn't slow down in the least, murmuring words of encouragement as his lips travelled on Keigo's cheek, chin and neck, leaving more marks of his own there.
His endurance was unmatchable. Just holding on and trying to keep up took everything Keigo had.
The pointy tip of Touya's tail brushed against his thigh, caressing him before travelling up to where Touya and Keigo were joined. When it dipped into the generous mix of slick and precum flowing out of Keigo before moving lower and lower and playing with his ass... Keigo just stopped thinking.
All he could do was feel.
He couldn't tell how many more times he came before finally, finally Touya stilled and pulsed inside of him. Keigo drank in his blissed out expression, committing every bit of it to memory before pulling him down for a kiss.
Perfect. Just, perfect.
They fit together so well.
Still sheathed in Keigo, Touya gently lay on top of him as they caught their breath.
Eventually, Keigo's mind cleared and he bit Touya's ear before whispering into it.
"More?"
Touya's laughter made his heart flutter. Still, he made sure to complain when Touya just carried him up into his arms before walking to Keigo's bedroom.
That unearned, magical strength was absolutely unfair.
Keigo woke up to the smell and sounds of breakfast cooking. After stretching his pleasantly sore body, he put on a sports bra and underwear, and once in the living room picked up Touya's t-shirt from the floor to pull it over his head.
Touya was in front of the stove, no horns or tattoos in sight, hair back to black. This also suited him. Careful not to distract him too much, Keigo briefly kissed the largest hickey on the side of his neck. Then he sat at the table and observed his back, content to admire the marks he could see on Touya's neck and arms in the comfortable silence. His marks.
It'd be even nicer if Touya cooked naked so he could see the rest, but this would have to do for now.
When Touya joined him with two plates, Keigo decided it was time to clarify a few things.
"So..." he started. "That was the first time we had sex, right?"
Those dreams had been too realistic and sudden to be natural. Touya didn't seem too impressed with his question, however.
"Yes?" he eventually answered, his tone clearly indicating his concern about Keigo's mental capacity.
"And sex demons can't walk dreams?" he asked, hoping Touya would either betray himself or move on to another topic.
For a moment, Touya looked bewildered. Then, a really obnoxious smile stretched his lips. Damn it. Touya crossed his hands and rested his chin on them.
"Takami Keigo. You horny little man. What was I doing to you? Tell me."
"Nothing we haven't done since then anyway," Keigo mumbled. "Let's just forget about this."
"No, no, no. This won't do. I have to be more creative than dream-me. Now, finish your food and we're going to rectify this immediately."
Keigo shook his head and chuckled, smiling. Eager. His theory had been proven wrong, apparently, but he was used to that. He could work with the new information.
"Whatever you say."
He might have finished his breakfast faster than strictly healthy, but then again Touya's cooking always tasted the best.
Epilogue
"You've finally figured it out," Toga said with a sigh as she moved the needle on Keigo's back. "You were both so obvious with the pining. I've literally been weaving this spell with love magic since day one. Way more powerful this way. Probably gave Keigo some very nice dreams, too. You guys are so dumb. And slow. Especially you, Dabi."
"He is," Keigo agreed, mostly to annoy Touya but, really.
There was some truth to it as well. Touya had had more information than Keigo from the start. And needling Touya while Keigo suffered under repeated needle stabbing only felt fair.
"I can't believe you didn't even recognise Mr Compress," Toga said. "He said you were sooo scary when you threatened him away from Keigo..."
"I'd never seen Mister without his mask before, give me a break. Couldn't Shigaraki just like, come talk to me like a normal person instead of sending him?"
"Of course not," Toga joyfully said, never slowing down in her work. "He's still grounded in the demon world."
Even if he joked about the stabbing, Keigo had to grit his teeth through some of the process. This wasn't awful but wouldn't feature in a top 10 of the best experiences of his life either. Top 50. Just focusing on their conversation provided a good distraction.
"He misses you!" Toga continued. "You should go and say hi."
"I can't. I'm still stuck here and the joke's on him because I'm definitely not going back after he put Keigo in danger."
"Wait," Keigo said. "But I want to meet your friends, too."
"No, you don't. Mister nearly killed you with his horrible ugly gift and he didn't even mean to."
"Ow, you're so mean Dabi. He made it himself. So it'd look as close to you as possible."
"I knew it reminded me of something!" Keigo exclaimed.
"Don't move," Toga growled, pushing him back down. "Or I'll stab you with something more painful."
"Sure, sure," Keigo said. "But the patterns looked familiar! Now I get it. They're based on your tattoos."
"Just shut up. I look nothing like that thing."
Toga laughed. "They're so distinctive. Still can't believe a child's drawing was enough for the entire demon world to know you were the one prancing around without glamour again."
"Anyway, I'm gonna delete the blog so you should be able to hang out with your friends again. And introduce me!"
The needle paused for a moment.
"You will?" Toga and Dabi asked at the same time.
"Of course! I don't need it anymore. I found my demon, now."
Keigo wished he had some magical powers of his own, so he could store Touya's current expression in a capsule forever.
His curiosity about the paranormal hadn't lessened one bit but he didn't need to share his passion with the world anymore, as long as he could share it with Touya. Making a living without the sponsorship money might be difficult at first but he'd work something out.
To start with, they could probably downsize to a one-bedroom apartment, now they didn't need the extra room anymore.
Plenty of options there. Whatever the future held, they would figure it out together. Without secrets and with a lot of supernatural shenanigans. Probably copious amounts of sex, too.
Keigo couldn't wait.
