Chapter Text
Idiot.
San awoke in an empty bed. For a brief moment, he rolled over, hoping to find Yunho curled up next to him, still sleeping as well. But it was a foolish fantasy. He’d been tricked, and the incubus wasn’t there. He wasn’t in the house either.
Yunho was long gone, and he cursed himself for falling for his tricks-- the incubus has distracted him and escaped while San slept.
Idiot, idiot, idiot. San couldn’t scold himself enough. He’d fallen for the easiest trick in the book. He’d let a powerful demon escape from his grasp, when he had him completely. It was so easy, he could’ve killed Yunho, but instead he’d fucking slept with him. Fool.
San spent some more time in the apartment, going through the few things Yunho had-- it seemed to be a prefurnished place, and he didn’t own much else. The apartment was under an alias, he came to learn, which of course, was no fucking help, and there was nothing to clue him on to where Yunho might have gone.
A hope stayed in San’s mind that Yunho might be dumb enough to try and return, but of course, he wasn’t. He was too smart for that, and despite all San’s efforts to try and figure out where the incubus had gone, the trail had gone cold.
To think that Yunho had been handed to him on a silver fucking platter but somehow he’d fallen for it.
After a couple of days, San found himself no longer having an excuse to stay in the apartment-- he’d rooted through every drawer and searched every nook and cranny, read through every paper and examined every piece of junk. But yet, he was still there, and ashamedly enough, was still sleeping in Yunho’s bed.
San went to collect his things from the motel he was staying at, his books of demon lore and his small weapons stash, plus the rest of his warding charms and whatever else he was able to carry with him. Since he was now back to square one, it was all about research. Despite having gone through the lore hundreds of times, he still hoped that he would find a scrap of something to clue him on how to track Yunho.
What was even more embarrassing than staying in the apartment was how he just couldn’t stop thinking about Yunho. Fucking. Constantly. San couldn’t help chasing that feeling, that immense pleasure. He found himself with his hand fisted around his cock moaning Yunho’s name far too many times to be okay with, imagining the boy’s pretty whines and his golden eyes as San fucked him. He chased other fantasies too, ones that he was more ashamed of, Yunho marking him…
San cursed himself even more when he came across the scrap of lore that some people believed having sex with an incubus created some sort of bond between the two; something that only grew with more encounters. San had fucking bound himself to the demon.
It was even worse being constantly surrounded by Yunho’s scent. It made San feel slutty, picking a shirt in his drawer and breathing in that strong musk, even if it was faded. San craved Yunho’s energy again. It was addicting.
San dreamt, too, of Yunho’s pretty lips and of his pretty cock and his long neck and his perfect fucking body proportions -- goddamnit. He really couldn’t get over it, no matter how much he forced himself into his work and tried to distract himself. He hunted down those who’d slept with Yunho, all in various degrees of chasing that energy again. San came to learn that every person Yunho had slept with was the same as him… he hadn’t taken anything without permission.
But no one knew where he might’ve went, not the bartender, not his landlord, no one. So San was stuck in limbo, torn between chasing to kill the demon and chasing to… He wasn’t sure. He felt like he needed Yunho. Desperately.
One night, San found himself drinking far too much, just trying to clear his head, or get Yunho out of it. He stumbled back to the apartment, barely able to see straight, and collapsed in Yunho’s bed, smushing his face in the pillow that was quickly losing his scent. In a collapse of judgement, San grabbed one of Yunho’s shirts out of the drawer and put it on. He was too drunk to care. He just wanted the stupid incubus back.
--------------------------------
San awoke, disoriented. He vaguely remembered falling asleep drunk, but his head was clear now, although he was still in Yunho’s room, Yunho’s bed, Yunho’s shirt. Something was wrong.
“You know, I’m pretty flattered. If only you could also feel the amount of desire radiating off you. All of this, for me?”
That sultry voice, again, reverberating through all of him. San was already so overwhelmed with need, it ached, pulsating through him.
Yunho appeared before him, golden eyes standing out against the darkness of the room, little suns.
“Why are you here.” San said, his teeth gritted, unwilling to express the part of him that was grateful for this, screaming for him. How badly he’d wanted this. Needed this.
“I think you know why I’m here, San.” Yunho said, approaching the bed and taking a seat next to him. His hand reached out to brush aside a strand of San’s hair. Even that made him shiver.
“You left.”
“Well, you were going to kill me, weren’t you?” A small smile across his face, cocky.
“That was my intent.” San said. It felt like every nerve in his body was screaming. In this dream space, it didn’t take much for Yunho’s energy to permeate everything, and it was driving him crazy. He’d been chasing fantasies like this for weeks.
“And do you want to kill me now?”
San thought for a moment. Every hunter’s instinct in his body, everything he’d learned over the years, was telling him yes. This was his job. No, not his job, his mission, and he couldn’t fail it. But…
Yunho hadn’t ever done anything wrong. He couldn’t control what he was, and from what San had gathered he hadn’t caused pain, aside from the repercussions of what he was. And he had to admit to himself that he’d done nothing but think about this moment for some time now. Maybe his opinion had changed, maybe his desire was overcoming him.
“No.”
It was the truth, and it fully reverberated throughout the room. It instilled a cold silence through both of them, and Yunho smiled softly, like he’d already known the answer.
“Then what do you want?”
The cocky fucking bastard.
“Are you really going to make me say it?”
Yunho chuckled. “It’s my rule, you know that.”
San wanted to whine. He didn’t want to say it out loud. He’d been trying to bury the thought, but he’d been cumming to the fantasy over and over again.
“I want you.” San’s eyes met Yunho’s again. “Please.” His voice cracked. He could feel himself already getting hard, aching everywhere just for Yunho to touch him.
“How could I say no to such a pretty face?”
In a moment, Yunho had his fingers on San’s jawline and was kissing him, sending waves of energy and heat throughout his body. God, he’d fucking craved this. He parted his mouth to allow more, Yunho’s tongue tracing his lips, and it drove him even crazier. He couldn’t help but whine into Yunho’s mouth, hoping he wouldn’t notice. But as the kiss broke, he could tell that he had.
“Really, are you that needy already?”
San bit another whine in, staring downwards. He really didn’t like feeling this desperate, this submissive. It was an entirely new feeling. He was exposed.
“Come on, tell me.” Yunho said, lifting San’s chin so their eyes were locked. “Tell me how bad it is, baby.”
San felt humiliated. He felt so weak, completely at the mercy of the incubus, and he hated how much he was loving it. He’d needed this so badly.
“It’s really bad.” His voice was quiet.
Despite how close they were, and the fact that Yunho could definitely hear him, he still asked, “Louder, baby.”
“It’s really bad, Yunho.” His voice was steadier.
“Daddy.”
San felt himself blushing. How much power he’d lost, that he was now melting under just the slightest touch and the simplest words.
“It’s really bad, d-daddy.”
“Good.” His voice was so heavy and thick with praise, it made San shiver. He really liked hearing that. His cock was getting harder and harder underneath the covers.
It was getting more obvious that Yunho was loving this, loving dragging this out and teasing San, that San’s desire was addicting to him. Yunho released San’s chin in favor of dragging his tongue across his jawline, biting his earlobe, tracing it down his neck. Yunho took his skin into his mouth, biting and sucking a deep purple mark. It was embarrassing how needy this made San feel, and he whimpered at the electric shocks that were coursing through his body.
“I love how you sound.” Yunho’s voice was so fucking pretty. “Let me hear you, baby.”
Just that made it easier for San to let go as Yunho kept marking his neck, his big hand pushing San back so he was lying down, one swift movement. He lifted up his chin so he could give Yunho more access, whimpering as he bit harder. Yunho kept at it, marking several places before deciding he was satisfied.
“Let’s take this off.” Yunho said, grabbing at the hem of the shirt. He paused for a moment, having not noticed this detail before. “My shirt?”
San couldn’t help the blush. “Y-yes.”
“That’s cute.” Yunho said, moving away so San could pull of his shirt, tossing it aside. Yunho was immediately handsy, drawing small whines out of San as he traced his skin with his fingers and his tongue, taking one of San’s sensitive nipples into his mouth. A small ahh escaped San, which made him even more involved, teasing it with his tongue. When he felt satisfied again, he kept kissing and sucking marks around San’s hips, pushing back the covers to discover that drunk San had opted to sleep without boxers.
“Oh?” His voice was teasing. “My shirt and no underwear?”
“Well,” San realized that he honestly had no excuse. “Yes, daddy.”
“I like that.” His voice was so fucking seductive, as he kissed around San’s thighs, driving him crazy with how Yunho seemed to be purposely neglecting his hard cock. But god, it still felt so good, just him touching San’s thighs, marking the sensitive inner skin, heat waves and gold light through him. Yunho stopped abruptly.
“Why have you stopped with those pretty noises, baby? Is this not enough for you?” God, his voice was fucking gorgeous, teasing him. “Do you need this?”
His hand suddenly fisted around San’s cock, his thumb brushing over the tip, spreading precome. San bucked up into his hand, his moan half surprise and half pleasure. He felt even more sensitive, it being Yunho’s touch and not his own. But Yunho didn’t continue, and San assumed it was because he wanted a response.
“Y-yes please daddy,” San said, his voice a breathy whine. He needed exactly that, and he needed it so fucking badly.
“I wanna hear you then, baby.”
Yunho kept with it, teasing the tip of San’s cock as he jerked him off as well, and San let himself be vulnerable, whining with every slight movement and moaning loud as all hell.
“D-daddy, getting close--” He cried.
“You’re so easy, baby.” Yunho said. “Go on, cum.”
A couple more movements and San’s orgasm washed over him hard, a moan escaping him as he bucked one last time into Yunho’s fist, whining high.
“Good boy.” Yunho said as he came, stroking him through his orgasm, milking him dry. Yunho licked San’s cum off his hand. “You know, you taste really good.”
“Come here next time you need me.” Yunho said, placing a small scrap of paper in San’s hand. “I’ll be there.”
And before San could say another word, he was gone.
-------------------------------------------------
San wanted to be ashamed of it. He wished he could’ve tucked those feelings away and never think about Yunho again, but he couldn’t. He was going already crazy within a day, aching like crazy but not wanting to jerk himself off, it wouldn’t be good enough. He’d just be aching again within an hour, and it wouldn’t change anything.
He spent forever staring at the address scrawled on that slip of paper, going back and forth on how stupid it was to go but how badly he fucking wanted it, how by each passing hour he was losing control of himself and his ability to say no. The dream had felt so real, and that mark on his neck was driving him crazy, like he’d been branded. Like Yunho had made a point to show San that he was his property, that he wouldn’t just be able to brush his experience with Yunho off. It was quickly becoming far too much.
It was like he was barely in control when he found himself telling the address to the taxi driver, his thighs shaking. He hadn’t stopped sweating for what seemed like ages. He rested his head back on the seat, closing his eyes shut. It was getting worse. And this was going to make it even worse, but he couldn’t care, he just knew that he needed this, and he couldn’t wait any longer.
The building was even shittier than Yunho’s original apartment building, but he went up the stairs anyway, despite the flickering lights and the obvious sense of danger that the place stunk of. It didn’t matter.
San stormed down the hallway, and before he could bang on the door, Yunho opened it. His black shirt was most of the way unbuttoned and he had some sort of silver charm hanging around his neck, His hair was swept away from his face, revealing his forehead, and his smile was unbelievably fucking cocky.
“I knew you were coming.”
Asshole.
San wanted to say something rude, but Yunho was already pulling him through the door by the collar of his shirt, pressing him up against the wall. Yunho’s kiss was devouring, and San responded equally needy, digging his fingernails into his shoulder blades, a little whimper escaping into Yunho’s mouth.
“Really?” Yunho asked, hands on either side of San’s hips, keeping him firmly planted against the wall.
San was breathless. “Please.”
He leaned in for another kiss, swiping his tongue across San’s lips before taking his bottom lip and biting it. He broke the kiss again as he lifted San up, his legs wrapping around Yunho’s waist.
Yunho’s bedroom here seemed much more lived in than the one at the other apartment, with more objects scattered around, more things unorganized. He laid San on the bed, pinning him down again, another kiss, hungrier.
“Tell me what you want.”
There wasn’t a part of him that wanted to argue anymore. It was all long gone.
“You.”
Yunho didn’t hesitate before busying himself again, removing San’s jacket, pulling his shirt off, unbuttoning his own. “You look pretty like this, baby.”
San was still breathless, cheeks flushed, his body aching with need, chest rising and falling fast. He whimpered as Yunho palmed him through his pants, just the slightest touch too much. He was already so fucking sensitive.
“I have to warn you that it’s going to become much harder after this.” Yunho said. “You won’t be able to take this back.”
“I don’t care.” San leaned up to kiss him again, hands resting against the back of Yunho’s neck.
“Are you sure?” Yunho’s brow was furrowed. It was more than enough proof, just that moment and days of seeing the signs that he wasn’t evil. He’d changed San’s mind.
“Please, Yunho.” It was almost a whimper. He needed him so fucking badly.
“Hmm?” Yunho didn’t have to say anything. San knew what he wanted.
“Please, daddy.”
“Gladly.” His eyes were golden again, a soft smile across his face. Yunho pressed San flat against the bed, licking his neck and biting, harder than in the dream. He couldn’t help but whine. He felt like he was going to lose his mind already.
Yunho rested against San as he did so, and he could feel his bulge through his pants. San moved his hips just slightly, teasing the both of them. Yunho almost growled. “Don’t you fucking dare.”
God, he sounded so fucking hot like that. San wanted to push him, see how far he could go. He wiggled his hips again, just slightly, biting back the whimper from the stimulation. Yunho breathed out real softly, a subtle sign of his own pleasure.
“You really wanna get fucked that bad, huh?” His word sent shivers down San’s spine. He was getting so fucking hard and it hurt. The contact of Yunho’s skin on his was sending energy throughout him, and he didn’t want to wait any longer.
“Daddy, please.” San whimpered. “I need you.”
Yunho paused for a moment, still, before grinding down onto San. His hands clutched desperately, fingernails on Yunho’s bare skin. Every touch was fucking addicting. He felt so fucking big, and San felt so small against him as he rutted his hips into San’s.
“Let’s get these off.” Yunho said, unbuttoning San’s pants and pulling them off, his boxers with them. A brief moment of San’s fully bare skin hitting the air before Yunho had his hand fisted around San’s cock, adjusting himself so he could lick the precome from the tip. The noises San were making were downright slutty, and he didn’t care, Yunho taking his length into his mouth, running his tongue down the shaft, up and down again.
San bucked his hips, desperate. “P-please.”
Yunho removed his mouth, a soft pop. “Stay still and daddy will take good care of you, babyboy.”
This was exactly what San was addicted to. His words calling him babyboy before he took San into his mouth again. He had to force himself to stay still, the sensation of Yunho’s split tongue on him almost too much to bear. He was so fucking good with his mouth.
The fire in his stomach was growing, and he could tell that Yunho was amping it up, turning up every sensation to 10.
“G-gonna c-cum,” San moaned. “Daddy, ah--”
Yunho didn’t give into that, however. His mouth was already gone. “But don’t you want to come on daddy’s cock?”
Fuck. San whined from the back of his throat, he ached so much.
“P-please daddy.”
Yunho didn’t need another word. He reached aside to grab the lube from the bedside drawer, lubing his fingers quickly, pausing to slowly rub his thumb across San’s opening. Just the smallest touch was like shocks through his body. Yunho was really amping it up now, driving him crazy on purpose, his energy powerful and heavy. San whined as he pressed harder, working his thumb into San. His whines were getting noisier and noisier.
“Daddy, ah, ah--” San whimpered as Yunho lazily finger fucked him, not bothering to conform to his obvious desperateness. His teasing was so purposeful, so pointed to drive San crazy and arch his back, hips wanting to grind for more.
Yunho pressed another finger inside him, scissoring them apart, gently working San open. “You’re doing so good for me, baby.” God, the praise was so much, fire across his skin.
“Daddy, please.” San moaned.
“You want me to fuck you, baby?”
“Fuck, please daddy.” The words slipped out of him fast. “Need you.”
Yunho smiled at the pure need in his voice. He removed his own pants and boxers, and it seemed painfully slow to San. He wanted to cry. He was just purely teasing at this point.
Once his cock was freed, San couldn’t help but whine softly. Yunho looked so fucking big, and he couldn’t help but ache. Yunho adjusted San so his legs were thrown over his shoulders, his thighs parted and spread wide.
“Want to beg for me, baby?”
The words spilled so freely from his mouth. “Daddy, please want you to fuck me please, please, fill me up and fuck me, please.” His voice was pitched and whiny and so damn submissive but San didn’t care.
It felt so good as Yunho pressed the tip of his flushed cock against San’s hole, slowly pushing his length into him. A high pitched whine crept in the back of San’s throat.
“You’re so cute like this.”
One more final push and Yunho was balls deep. He stayed still for a moment, allowing San to adjust to him.
“Please, don’t wait any longer.” San whined, grabbing Yunho’s wrist and interlacing their fingers. Yunho smiled as he grabbed San’s hip with his free hand to steady himself and began to thrust slowly, pulling almost all the way out before thrusting in, hard. San gasped and moaned, fingernails digging into the back of his hand.
His thrusts were sloppy and the only sounds that filled the room were the sounds of skin and San’s pretty moans above Yunho’s quiet groans.
“Daddy, gonna c-cum,” San stuttered out, barely able to speak as Yunho hit his sweet spot.
Yunho’s voice was sweet and sticky. “Already, baby?”
“Y-yes daddy.”
He fisted his hand around San’s cock, squeezing it, and it was all San needed. He came with a loud cry, making a mess of the both of them. Yunho fucked him through his orgasm, getting rougher and rougher until he came, digging his fingernails in. He came not soon after, pulling out to cum over San’s stomach, a deep moan and a dark look in his eyes.
Yunho laid next to San, both of their chests rising and falling at a fast pace.
“T-that was so good.” San’s voice was hushed.
“You did so good, baby.”
For a moment, everything was silent.
“I think it’s fair to say that you’re mine, now.”
