There are many different kinds of demons. Every kind is similar to humans in at least one way. 

Take, a sex demon, for example. There were two kinds: like in body, and like in mind.

Those who were like in body would experience pain if it were inflicted on them. They had only a bit more stamina than the most durable of humans. They would not be fulfilled by emotional connection, but it didn’t matter to them, as they drained their victims of energy they could never regain, leading them to an earlier death. 

Those who were like in mind were prone to human-like emotion. That made them vulnerable. Despite the flexibility in their bodies, their strength and durability, their tolerance for pain to a drastic degree, they were susceptible to manipulation. To some degree, of course. They were only as naive as one could be with free reign as far as they pleased.

Song Mingi, a demon like-mind to humans. A body built to please, which he prided himself on. He was wild. He belonged nowhere, but he believed he did not need to. He had never been denied what he wanted, as his instincts were never wrong.

Bodies moved around him. The lights were dim in this place, but the music was loud, filling every ounce of space with sound. He could feel the bass in the floor under his feet.

He loved parties. He liked the crowd and the excitement. He became accustomed to the behavior of humans, their urges and how easily they would give in to them. He liked to watch . And sometimes, he liked to stir up his own mess. His energy came from these types of places, the kind overflowing with untamed sexual energy. They were all over each other already, drinking, kissing, dancing, some things that looked like they were meant to be dancing, but did not quite cut it- the works.

Usually, in this scene, he would let his instinct guide him. He could sense need, smell desire of a specific kind. But sometimes, very rarely, his curiosity outweighed instinct.

For some time, he’d had his eyes on a particular human . It was the first time he’d ever felt the need to tread lightly, and that made him buzz with excitement. He faced a form of vulnerability he’d never once encountered before. A human who could see him .

Now, a demon could be visible to a human. If they decided to make it so, they could meet and interact as if they were human themselves, but they possessed the ability to become hidden to human eyes at any moment. The first time Mingi had caught this human’s eyes on him, no one else could see him.

Those eyes saw into his own, right down to his core which soon burned hot as Hell under the gaze. He was struck. Shocked and curious, and while he wouldn’t admit it, he was almost desperate to feel more of it.

What was happening to him? 

Mingi’s instinct told him no . This man was not like any human he’d been with. To begin with, most had been women. The rare occurrences where he’d been close to a male human hadn’t been enough for him to question what it’d feel like to be in their place . But the look from this one human did. 

Mingi would tame him.

He was a demon, after all. He was built to be dominant and dependable. Humans never did experience anything like him again. And, while he never felt the need to take on a challenge, he needed to know just who the man with the gorgeous sharp features was. 

He was no coward. He could face a human- easily, even.

He ran his fingers through his hair, long down his neck, naturally silver. His eyes were a striking gray as well. Most humans assumed they were contacts, which he let slide. 

He’d have to do without that delicious attention for now. There was someone he wanted it from.

He pushed his way past people. Some would turn around, and scowl at others behind them, to which some other human would be confused or feel threatened, unprovoked. They were fun that way. Mingi paid them no mind as he made his way toward the bar. His broad frame displaced many people, most of whom ignored it and went about their business.

He was far too occupied to be concerned.

His attention was drawn to a body, broad shouldered, but not quite as tall or as large as himself. Black hair slicked back, a sharp jawline he caught a glimpse of when the man turned his head. A slit in his eyebrow. His lips pretty and red. The demon wanted to kiss them.

“Alone, tonight? Can I interest you in some company?” 

The man doesn’t raise his head, he only laughs, as if he’s amused by the demon. Something boils in Mingi’s chest. Surely, it’s the need to put this one in his place .

“You mean you finally decided to come and talk to me?” He was right, then. Not only could the man see him, but he’d also noticed he was being followed. But… that voice. More like the tone of it. It’s deep, laced in a sexy accent, one Mingi wished he could replicate. He talks down on Mingi so easily. He’d never spoken to the demon before, but he already had an edge up.

Mingi had never lost this game.

“I didn’t mean to keep you waiting, gorgeous,” He took the empty seat next to the man, calculating his movements down to their pace, “But, if you wanted to talk, you could have stopped pretending I wasn’t there.” He accused.

As many times as he’d seen the man, they only made eye contact twice. He couldn’t really be sure until right now, but he was already wishing he’d planned better. He’s struggling to hide how his gut is telling him this isn’t what he’s used to. How the lights are flashing red, but he’d never been so attracted to a man before and he was nothing if not impulsive.

“And then what? I don’t even know what you want from me, demon.”

Mingi clicked his tongue. “Demon?”

The game really begins the first time the human looks at him, their eyes meeting, and locking together. Mingi felt like he had that first time. Like he was a rabbit caught by a fox, who never would be able to escape. 

He was not the prey. He was a demon, a selfish one who took pleasure and ruined humans for anyone else. His touch was perfect, and addictive, and no one pleased like he did.

This human would soon learn. Mingi couldn’t wait for the moment those eyes went soft, and glistened as the smell of pure lust filled the air. No fight left in him.

He grinned, flashing his pretty smile at the man. 

"Me? Of course not." Mingi placed a hand to his chest, selling his sincerity. "I'm actually from Heaven. I was born right up there, see?" He points upward with his free hand and the man’s gaze follows.

He continues when those eyes fall back on him. "In the Paradise Hospital. My wings were removed before I was given to my parents, just so that I could end up right here with you." Mingi winks at him. 

He receives an eye roll.

If you see them, they notice. San had learned this, among many other things, growing up with this ability.

They took an interest in you when they realized you weren’t like other humans. Give them an inch and they’ll take a mile. He’d become very good at ignoring things, but it also made him much more vigilant. He wouldn’t fall for a demon’s trick, and he certainly wouldn’t play a demon’s game.

This particular one seemed to like hide-and-seek.

His mistake was not realizing this was a demon. He never should have looked back after the first time they locked eyes.

This one was tall, and quite broad. He dressed in black from head to toe, and his clothing was glistening with stones and jewels. Humans didn’t wear those things just anywhere. San recognized a demon, and yet, he glanced a second time at that wild, silver hair. 

To his defense, they were gorgeous. That’s all he had to add.

But, from then on, his eyes had found theirs a few more times. Right, he’d trapped himself this time. There wasn’t much he could do about a demon while in public. The vast majority of humans didn’t even believe in them, or at least, that they could really interact with humans. It would make more sense to put him in therapy than to file a restraining order against a troublesome, invisible Creature From Hell.

That left him here, entertaining this demon who seemed to enjoy lying through his teeth.

He sighs.

"…I know you're not from Heaven. I don't see angels." And thank the Heavens for that, because he hears they're actually quite unpleasant.

"Well," The demon pouts, "Then you've obviously never looked in a mirror before."

The flirting with this guy.

He raises a brow. The pout is cute, at least. His lips are plump and sweet, and it softens up the rest of his features, like his pointed nose. San would even say they’re heart-shaped , and that he wonders for a moment what they’d look and feel like wrapped around him.

He had considered taking someone home anyway. 

“What’s your name?” He decides to ask.

“My name is Song Mingi.” The demon answers proudly. San scans his expression and accepts that he’s not bullshitting this time. Song Mingi. Lovely name. “And yours?”

“Choi San.”

In some cases, you should avoid telling a demon your name. That was a given. But Mingi wasn’t a threat to him. If San was in any danger, he would have been harmed already. 

San was also the slightest bit impulsive, operating on optimism and assuming the best of situations regardless of their context. So, who knows. Maybe he will die.

“Choi San.” The demon repeats back to him in thought. It seems he thought the name was familiar, but he threw away the idea in favor of- “I’d love to moan that for you.” He purrs. Of course.

San was generally aware of the categories demons came in.

Mingi was a sex demon. If he wasn’t, he wouldn’t be here right now. They were really the only kind who got this close to humans. The others who did were never visible- like the non-humanoid ones, the creatures who caused problems simply because they could.

As for the sub-categories… He was screwed in that department. He never did enjoy studying, and while he did know them at some point, the ones he hadn’t personally come across began to slip his mind.

And so he tried to recall the basics. He remembers being a teen, curious about what a sex demon could offer. He never did know for sure. The books didn’t go into excruciating detail- only that they made physical energy from sexual energy, and that the best way to do so was through sexual activity- boring shit.

Song Mingi would be the first he’d met.

“Mingi, how about we go somewhere else? I probably look crazy talking to myself like this, don’t you think?”

Mingi couldn’t agree more.

He wanted Choi San out of that seat, and probably against a wall somewhere, screaming his name. The demon smirks, leaning in so the man can hear his whisper above the club speakers.

“I’d love that, baby.”

He let the human lead him out of the place. They round a corner and make their way to a car. Mingi assumes it’s San’s. He gets pushed into his seat, much to his displeasure. Fine. He could wait until they got to the place.

“It’s not far.” He’s told as the human starts to drive. “You can keep your hands to yourself until we get to my place, can’t you?”

“I won’t be any trouble.” He insists, crossing his arms with an eye roll as the human starts the car and pulls out of the lot.

San hums. “Why don’t you tell me what you want to do once we get there, hmm?”

“I’m not sure what you mean.”

“No?” San is surprised to say the least. What was there to misunderstand? “You don’t know how to get your partner going without touching them, Mingi?”

The demon shoots him a look, which he does not reciprocate as he drives with his eyes on the road. Mingi cannot imagine why a human would be speaking to him this way. What did the man expect him to do while he was confined to this leather seat? Can they not just arrive faster so he can have his fun?

He neglects to offer up an answer, which must irk the man driving.

“Such a pretty voice and you don’t know how to use it, is that right?”

“What are you on about…” Mingi mumbles.

“What did you think we were going to do in my car? Before I told you to sit still.”

I told you to sit still. How fucking smug. Mingi didn’t take orders.

“...Make out, probably. It’s a little small for fucking in the back seat.” He adds the last bit as a jab back at San.

“How so?” It’s not quite wounded enough. San seems to be enjoying this. His amusement is starting to annoy the demon. How fucking far away is it?

“Well, for one, the ceiling is a little low for any fancy positions. That’s half the magic.”

“Tell me about the magic, Mingi. I’d love to hear it.”

It’s beginning to piss him off. San is trying to get something specific out of him, and he’s beating hard around the bush like he expects it to take a while. The demon grows more and more impatient- he’s already tenting in his pants, waiting to get the hands on that steering wheel onto him instead.

“The magic, baby? I’m a demon, I’ve been doing this since I was created. You wouldn’t believe the things I could do to you.”

San chuckles. “That sounds riveting, oh vague and powerful one.” The demon’s blood is boiling at the condescending tone. He’s far from being taken seriously. He could leave this man’s body in a ditch somewhere with little to no issue, and he’s allowing himself to be taunted like this?

Not that Mingi could bring himself to actually kill a human.

That was messy. A disgusting process, really. But Choi San could not know that for sure.

“What are you getting at?” He bites out.

The smirk on that man’s face would be the first thing to go, he decides. He’d kiss it away, steal his breath, and then move on from there.

“Using your words, of course.” San chirps. “I’m sure you’ve been in some interesting positions. I assumed you’d be able to paint some pretty pictures for me.”

They’re stopped at a red light, and they look at each other, the light coloring them crimson as they exchange expressions.

“I’m sure you do this a lot, Mingi. But I’m afraid that doesn’t mean you know how to enjoy it.”

The light flickers to green and the demon hisses. 

“Drive.”

San does so without any more comments, to his satisfaction.

In the minute or two that followed, San’s statement plagued him. Of course he enjoyed sex. He enjoyed it when the other did. He wasn’t interested in slow or quiet. Nothing shows off his ability, his power like rendering some helpless human entirely drunk on pleasure. Not only was he fucking skilled, but he had a fucking fantastic time proving it, damnit.

And who was Choi San to question him?

They finally pull into a driveway. San’s place.

“Wasn’t too bad, was it?” San parks the car and Mingi is already out the door. It’s dark out, and the front door of the human’s house isn’t lit. Once the two of them are by the door, he watches impatiently as San unlocks it. He’s taking his sweet time pulling out his keys. “You look like you have half the mind to start playing right here, Minmin.”

…Minmin ?

Mingi had never been given a nickname before. 

San pushes the door open, and the demon is finished waiting once he’s on the other side of it. San doesn’t seem to mind, which only serves to spur him on. 

Mingi pushes San against the door. San reaches down to lock the door behind them, then tangles his fingers in the demon’s silver, wolf-like hair and pulls him down for a kiss. Mingi has to be at least a full head taller than him, but he decides that he likes that. A lot.

San finds it delicious, the way Mingi’s body cages him in, and covers him completely.

The demon growls into the kiss, a rumble deep in his chest. Mingi is a demanding kisser, making quick and harsh movements with his lips and his tongue, but his pillowy, heart-shaped lips mellow it down. He feels the demon pull him closer by his hips, large hands gripping his thighs and waist, and a firm yet soft body pressed flush against him.

San tilts his head into the kiss, and accepts Mingi’s tongue into his mouth greedily, swirling his own around it. Mingi tastes like mango. It makes San moan. He loves sweet things.

He’s excited to find out who will swallow the other down first.

“Mhm- Right to the point, Mingi? You just can’t help yourself, can you?” He moans between harsh kisses.

Mingi can help himself, the demon thinks. If anything, this human should be begging on his knees now, crying at his feet for all he has to offer. He would make Choi San crumble and fall apart for him.

At least, he planned on it.

He wasn’t sure why it wasn’t done already. He didn’t exactly get the chance to experiment. He didn’t have to. Wherever his instinct came from, it knew better than his brain what to expect, but it wasn’t very helpful once he’d decided to ignore it.

Curiosity kills the cat.

Mingi is in his head long enough for San to flip them around, slamming the demon against the door and attacking him again, biting down on Mingi’s neck in a sensitive spot that makes him howl. 

Mingi’s head falls to the side, exposing more of his neck for San’s enjoyment.

He’s not supposed to let this happen. He’s supposed to turn the tables again, establish that he’s in charge… but this feels… fucking good. His back hitting the wall, the harsh bites to his throat like this man owns him- If he pushed San away now, he wouldn’t know what to do with himself.

"What do you… W-what do you like, Choi San?" The demon gasps between bites. San could tell he was searching for the upper hand, and couldn't help but smirk into his throat.

"Mingi… I’d like," He takes one of the demon's wrists and pins it to the door by their heads, "To see you realize how badly you want to submit to me."

Submit.

That was it. That was the thing he felt before, the thing he wasn’t used to. It was a heady feeling, one that took him over regardless of what his body was capable of, because of how it made his head foggy and his cheeks glow red.

Submit to a human?

San listened to the wheels ticking in his pretty head. He tilts his own to the side and grins, "I'll make you feel good, Minmin. There's no shame in getting what we both want, right?"

…Who would know if he let this happen? Who would hold it against him?

Mingi's arm stays pinned to the door when he loosens his grip and finally lets go. The demon looks down at him and bites at his bottom lip. San revels at the glazed look in his eyes.

"…I will." Rings the demon's deep voice.

No one will know.

San purrs, satisfied by the demon's response. He crowds Mingi closer to the door and admires the soft skin of the demon's neck. He wants to sink his teeth into it. So he does.

He continues to suck and bite, slipping his thigh between Mingi's and grinding it against the growing erection there.

Mingi is big - tall, broad shoulders, thick thighs, a cute butt, and San finds it difficult to wait when he could have that underneath him right now.

But a little patience goes a long way.

Now, Mingi is out of it.

The moment he committed to letting go, he lost his composure. He was chasing pleasure in ways he’d never considered doing before. It wasn’t a part of his performance. His expertise was in stability and deliberate actions. 

Submitting was a whole new thing. He was giving up a new part of himself.

The demon rut against San, his mouth open letting gorgeous moans spill past his lips. San slips his hands under the layers of Mingi's clothing, gripping his waist which fit perfectly in his hands. He needs to see it for himself, and so he finally starts to strip the demon. His coat comes off first. Then the shirt underneath, which he undoes button by button, licking and marking Mingi’s collar and chest as he reveals more skin.

Mingi is filled out, heavy and leaking in his pants. The human can feel it. His bulge is large. A crowd pleaser, no doubt.

San isn’t concerned with it.

“Take off your shoes and come here.” He orders the shirtless demon, who already has soft purple and red spots blooming on his body wherever the human could reach. San admires his handiwork as Mingi obeys absentmindedly. He slips his own shoes off and leads the demon to his room.

“Stand there.” He points at the edge of the bed as he flicks on the light.

He hasn’t decided to lay Mingi down just yet. Instead, he presses himself into the demon again and kisses him more, sliding mischievous hands over Mingi’s gorgeous figure. A narrow waist that dipped down toward his plump, round ass and plush thighs. San could admit that he was greedy. He wanted every inch of it.

He popped open the buttons on Mingi’s pants and lowered the zipper. Now he was getting to the main course. 

Mingi’s hands find his shoulders as his own dip down past his waistline, gripping two handfuls of his ass and playing with them until the fabric of the pants annoyed him. San pushes them down to the floor along with the underwear, and prompts the demon to step out of them. 

Mingi groans at the touches, willing himself to relax as the human plays with him. He was… enjoying this. His body certainly was, as his erection stands at full attention, aching for San’s hands. He feels something wet between his thighs and… Has San poured something on him?

How?

He gasps as a finger slips between his cheeks and prods at his hole- his entrance.

"Oh, would you look at this… "

San hisses at the feeling of him, both of them staring down at the tips of his fingers coated in the clear substance leaking from the demon’s hole. Mingi moans at the tone of his voice, deep and affected by him.

"What a perfect, slutty body you have, Mingi…"

Mingi whimpers. He’s never made that sound before. He’s never felt this hot, or been touched in these places. He’s never felt himself become wet like this. His body was responding to the human’s touches in ways he hadn’t expected, but it certainly eased his nerves.

He was made for this.

"I… It's built for whatever you'll do to me. It all feels good, all sounds good, j-just pleaseplease, give me more…"

Mingi grinds his hips down on San's thick fingers, desperate to feel them inside. His hands are gripping San’s shoulders like he’ll fall down if they don’t. The human coats the rest of the digits in his slick and finally slides two in together, filling Mingi deliciously for the first time.

He'd be addicted to Choi San soon enough, if this was all it took.

"Oh, oh fuck-" He moans, burying his face in the human’s neck. San’s fingers are big, and the stretch is good.

San curls his fingers and he nearly growls at the pressure against his walls. It's maddening. "See, I knew you had some manners in you. Unfortunately, you'll have to do more than ask nicely if you really want me to spoil you." Mingi lifts his head weakly, hips still rolling against the fingers in his hole, brows drawn in confusion at the man holding him up by his waist.

"You're not so used to desperation, are you, big boy?" San mocks, giggling. "That's okay, I'm gonna teach you a few things today."

Mingi groans, beyond aroused by the human teasing him, paired with the pleasure the man's hands brought him. San thrusts his fingers faster and more aggressively, toying with Mingi’s insides just to pull more sounds from him.

"First, we're gonna learn to beg properly. Then, we're gonna see how well you do with orders. Sound fun?” He asks, rubbing circles over the demon’s back with his free hand as if to comfort him. Like his torment wasn’t coming from his other hand.

But, for more of this?

"I- I can take orders, I can do anything..."

Mingi doesn’t think twice. Fuck. It felt as though San had unlocked a whole second set of instincts in him. He desired things he didn’t understand, things he had never  thought he could be on the receiving end of. He craved it.

"Oh, I bet you can, Minmin. You're so good at pleasing, so good with your big hands and big cock, hmm? Just a tall puppy, so bright-eyed, so eager to perform well."

Mingi nods, agreeing wholeheartedly. "Yes, yes I- I'm puppy... P-please, please more, give puppy more..."

"Such a good boy." San thoroughly enjoys himself, pulling at every string he can think of to see how the demon will react, and so far, he hasn't been disappointed. 

Mingi spreads his thighs wider apart and grips his shoulders tighter, coating San's hand further in slick, and San’s patience runs thin. He pulls his fingers away and ignores the whines from underneath him, finally pushing Mingi back onto the bed.

“Lay on your stomach.” He commands, but Mingi doesn’t comply quick enough, so he rolls the demon into the position he wants. Thighs spread, ass on perfect display, presented to him- slick and all. His tight, pink hole winks, leaking more. It coats the insides of his cheeks and trails down until it’s rolling down Mingi’s full, round balls.

San brings his slick-coated hand to his lips. He tastes the substance, and hums. It's a little salty, but far from bitter. It tastes like Mango, like his tongue. It's warm, tasty, good enough to drink a glassful of. San decides he wants more.

He flattens his tongue against his hole and licks a wet stripe over it, curling the tip of his tongue against it for just a second, prodding at it before he pulls away again. The demon jerks, hisses, and fails to contain a deep, lewd moan at the feeling of it.

"Let's try something more advanced, okay? How do you get your partner going without touching them?"

Mingi mourns the loss of the tongue on his ass. He whimpers, muffled by the bed as he wiggles his ass, begging wordlessly for more. He whines in question, to which San responds,

"Nope. Try again."

"H-huh…? P-please..."

"Closer."

"Please more, p-please..."

A palm comes down on Mingi's ass, snapping him out of his pleasure-induced tunnel-vision daze and leaving his right cheek stinging in a delicious way. That was all pain could do to his body- leave him stinging and blooming with mind-numbing pleasure. There was a time when a human had bit into his shoulder while he fucked into them. A wave of searing hot pleasure washed over him as he picked up his pace and left them screaming for him.

He moans and arches his back, pushing his ass upward in hopes of feeling it again. 

"How do you get your partner desperate without touching them, Mingi?"

He registers that San is talking to him, and manages to answer.

"…Y-you use your words…?"

San scoffs.

"That's all it takes to get you to listen? A little smack on your butt? That wasn't even a hard one..." San mumbles under his breath like he's disappointed at how easy Mingi really is, but the demon's cock- thick and heavy between his stomach and the bed- leaks pitifully at that tone.

"That's the next step to begging the right way," San continues with his lecture, spreading the demon apart with two handfuls of ass and licking over the slick rim again, "You can't just ask nicely. You have to convince me that I want it too. Everybody likes different stuff, and that means you've gotta find out how to do it just right."

"...H-how do I do it right? " Mingi questions, looking over his shoulder for a hint, in case San decides not to answer verbally.

He does.

"Do you want my tongue in your cunt, Mingi?"

It takes him a moment, but-

"Huh?"

San laughs at his gasp.

"You liked when I licked it? You want it inside you now, like my fingers were a little bit ago, don't you?"

"Y-yes, but-?"

"But? But what?"

Mingi sputtered, cheeks pink, unsure of what to say. San didn’t think that he… so why would he…

"I don't... I don't have that..."

"Don't have one? Oh, Mingi, who told you that?" San teases, massaging his ass cheeks like dough in both of his hands. "Are you trying to tell me this wet little hole right here isn't your pussy? So silly." He says as he admires it, kitty licking at it to gather more slick onto his tongue.

Arousal buzzes through him, making him squirm every time San uses one of those words.

"F-fuck... m-my pussy?"

"Mhmm." San never stops tonguing at his rim teasingly. He needs more, more.

"...Yes, y-yes I want it..."

"What do you want?" San hisses.

"I w-want it inside me, pleaseplease-"

"You're getting better. But, you've gotta be specific." San takes a break from tasting him, leaning over to speak directly into Mingi's ear. He just wants to be heard well.

"Do you want me to tongue-fuck your pussy? Hmm?" Another buzz, a full wave of arousal that makes his whole body vibrate and another glob of slick pour out of him.

"Yes... "

"Say it, then."

"San... Sannie, I really w-want..."

"Don't get shy on me, there's no shame in asking for what you want. No one else can hear you anyway, Minmin. Just be honest." San coaxes, peppering kisses on his cheek and the side of his neck.

"Sannie, fuck- please tongue-fuck my cunt..."

"See? Honesty can get you a long way, Minmin."

Choi San is a man true to his word, made evident when he dips his tongue into the demon’s twitching hole and eats him out like a starving man. Mingi all but screams, his thick thighs trembling as he fights to keep them spread.

Lewd sounds fill the room. The wet drag of San’s tongue inside him, his own cries of pleasure, and the pleased moaning of the man on his knees behind him. The sweet, fruit-like flavor becomes so abundant that it spills down his throat as he sucks and licks and he swallows it down enthusiastically.

It drips down his chin, down the demon’s already slick cheeks and onto his bed sheets. San’s shirt was surely ruined. His hands grab and his fingers claw at the demon’s ample ass and thighs; they’re round and cushiony, and they jiggle when he slaps them, making the demon groan louder and push his ass back against San’s face. 

“Ahh, oh, oh- oh hhhhh …”

Mingi’s voice is deep but his tone is high-pitched and needy. He sounded so good- from what San could hear with his face buried between his cheeks, drowning in sweet honey-like slick.

He couldn’t wait to be inside. His own cock twitched at the thought- that sweet, juicy pussy- but his hands were far too occupied to touch himself.

He kneads Mingi’s cheeks, spreading them wider for his tongue to travel deeper inside, and the demon begins to clench around him.

“Oh fu-“ Mingi hisses, “Fuck- I’m g-gonna cum- ah, please- don’t stop, please, I’ll be so good- “

The demon’s thighs tense up, and San adds a few well-placed slaps to Mingi’s ass as he sucks at the puckered rim and Mingi cums hard with the deepest fucking groan San has ever heard. 

He cums with his cock trapped under his body, clenching around San’s tongue, shaking, trembling, and San allows him to spill his sticky, white cum all over his sheets.

He can clean it later. Or maybe just replace them, if this night is going the direction he hopes.

His neck and chin are entirely soaked, so he leaves the room for a moment to retrieve a towel. He undresses, leaving his underwear on despite his aching cock trapped underneath the fabric leaving a dark spot at the tip- all he had on his mind was the demon boy. 

As he removes his shirt- stained beyond redemption-, he notices the bottle of lube he’d left on the bathroom counter. He laughs a little, finding it funny how useless the bottle turned out to be, and delighting in the fact that he could still taste Mingi’s slick on his tongue.

How lovely that was. Mingi was both delicious and soft. He would dream about diving in for seconds for many nights to come, but that would have to wait. He’d first toss the demon’s legs over his shoulders and stuff him so full of cock that he would cry.

He returns to the bedroom, having been gone for a maximum of 27 seconds, and what does he find?

A greedy, insatiable demon laying on his back, stuffing his dripping hole with his long fingers and begging an empty room for more.

San knows exactly what direction this night is going.

He would have it no other way.

“Princess. You’re in trouble.”

Mingi whines. Minmin. Puppy. Princess. He tosses his head back onto the bed and continues to indulge himself. San scoffs.

“Why do you not listen all of a sudden? You must be satisfied already…” He huffs, arms crossed over his chest, “I guess it’s time to clean up then. Come on, up.”

“N-no, no…”

“No? It’s not time? What do you want then, Minmin?” San teases him, sitting between the boy’s spread thighs, eyes trained on the fingers stretching out his slick hole… he’s so fuckable. Pure Sex was sitting in San’s bed and he had no complaints about it.

Except maybe that Pure Sex wasn’t a very good listener.

“Fuck me…? Please. Please.”

“How do you expect me to do that? You’re in my way.”

Mingi arches his back as he thrusts his fingers deeper inside his hole. They were fully soaked, glistening with sweet slick, and San was certain his sheets were ruined beyond repair at this moment. If he had to replace them, he might as well fuck a demon senseless on top of them first. He takes Mingi’s hips in his hands, admiring that little waist and bubble butt as he does so, and drags the demon down the bed until their bodies fit together. He slaps Mingi’s hand away, leaving him with a winking pink hole desperate to be filled and one needy slut writhing underneath him. 

“I really have to do everything myself, hmm? I thought you were learning well, but it seems like you need to be taught a lesson. Am I right?”

“...Please…?”

“Hmph.” He thinks, rubbing Mingi’s soft skin with his thumbs. “I guess it’s okay to be just a little dumb.” He decides.

San finally begins to indulge in himself. 

He presses his hips against Mingi’s ass, rutting his clothed cock against that wet hole and coating the fabric in that lovely, sticky substance. He groans, feeling his front become wet as he relieved some of the pressure in his gut. Mingi moaned as well, laying back and allowing himself to be handled by the human while his own hands clutched the comforter. The demon’s handsome face contorts in pleasure and his cheeks glow pink. San leans down, rocking his body against Mingi’s, and captures his plump bottom lip between his teeth. Mingi kisses him, slipping his long tongue into the human’s mouth once more as San uses him.

San wraps his arms around the demon’s waist and lifts his lower half off the bed, resting Mingi’s thighs on top of his own and grinding down harder, using the demon’s own body as leverage. The demon’s thick cock is trapped yet again between their bodies and San’s abdomen slides against him, making him moan.

“See, you’re doing so, s-so… good for me right now…” San groans between kisses. He watches Mingi’s eyes roll back as he says, “I’m gonna fuck your pussy so good… do you want that, Minmin?”

“Y-yes… Yes, w-want to feel you…” He felt San’s cock against him already. It was thick, like his own, and that was surely too much for a human to have. Mingi would be stretched spectacularly, and he’d beg for it up until the moment San stuffed him full with cum.

“…Don’t tell me you’ve forgotten our lesson. Tell me what you want, princess.”

Mingi whimpered. “Sannie, Sannie I really need you to fill my pussy... I- I need your cock so bad, please- please, give it to me.”

San sat up and stilled his hips. His underwear was soaked. San hissed as he removed the article of clothing, leaving them both completely undressed. The only thing to remain was the thick, silver chain around the demon’s neck, matching his wild hair.

San’s cock sprung free the moment he’d lowered them. It was flushed red with precum leaking down the side and already wet from the tip to the base. Mingi swallowed at the sight. He needed that.

The human wrapped a hand around his own cock and stroked up gently a few times before crawling forward. He pressed the tip against the demon’s hole and teased the rim. “Are you gonna be a good boy and cum on my cock? You’re gonna let me fuck your cunt and you’re not gonna touch yourself until I say so, right?”

The demon nodded, and while San had considered drawing this out more, he needed to be in Mingi’s guts at least a week ago.

He pushed forward, prepared to be engulfed by hot, slippery walls, but he wasn’t prepared for just how tight it was. Mingi had been stretched on his tongue and both of their fingers, but his hole was wrapped snuggly around San’s cock like it was made for him.

The demon let out a satisfied moan as he slid further inside.

“Yes, yesyesyes… t-that- that’s so good.”

Mingi felt every inch of San as he was filled up for the first time. The drag along his insides was addicting, and the heat drove him mad. The human’s slow pace was agonizing, but so satisfying. San’s hands on his hips, his cock twitching and throbbing inside him, filling him up to the base which was even thicker than the rest of it.

“S-San, please move, please fuck my pussy like you said- ”

San pulls back, delirious with pleasure, and stuffs his cock back inside Mingi’s hole hard enough for the demon to slide up the bed. Mingi screams.

He does it again.

“Y-you weren’t this tight ten minutes ago, princess.”

San began to speed up, fucking into him like a mad man. The demon laid back and took the rough treatment. San pounded deep inside him, his pace punishing and his grip bruising.

Mingi is loud. His cries and pleads and gasps were music to the human’s ears as he was split open and taken apart.

San was nearly dizzy. He’d never felt this fucking good before as he marked the demon up in every way possible. The dark spots littering the demon’s neck would surely last, and the ones his fingers would leave might also. The demon’s hole clenches tighter around him, and he slows to accommodate by reflex.

Mingi complains, and rocks his own hips to make up for it. San doesn’t care to put him back in his place. Nothing was hotter than having a man writhe pathetically underneath you. He pulls back and lets the head slip out, leaving Mingi empty.

“Wh-why? Don’t go, I need m-more…”

“I’m not going anywhere, Minmin.” He coos, rolling the demon onto his stomach, facing the sheets once more, and slipping back inside.

Mingi cries at the new angle, and this time, tears really begin to spill down his cheeks. Pleasure overtook him again as San stretched him wide and deeper. It blossoms in his gut, and seeps outward, his cock twitching and his hole clenching again. San sits up on his knees, plants his hands on the bed on either side of Mingi’s pretty head, and fucks him faster. Harder. Rougher. The demon could take it, sobbing or not.

“You’re crying? Are we ungrateful now, Song Mingi?”

“I- I just-”

"I'm giving you what you need, aren't I? I’m fucking your cunt just like I promised, right? Use your fucking manners." he growls, "Don't you have something to say to me?"

"I- Huh- uh, fuck-"

"Hmm? They don't teach you please and thank you in Hell?" He spits, thrusts never letting up as Mingi’s wet hole opens and sucks him in with each one.

"Thank y-you- fuck, thank you- you're- so good, so good- "

“Fuck…” San huffs as Mingi’s tight hole tries its damndest to milk him. He’s so close to pumping him full, but he hasn’t had all of his fun yet. He listens to the smack of the demon’s ass meeting his hips, and decides that Mingi may just have to take an extra load or two.

He shifts his weight onto one arm, fucking the trembling demon’s hole as deep as his cock will reach, and slaps Mingi’s ass with his free hand.

“Awh! ” Mingi howls at the sting. 

San slaps the same cheek two more times before switching to the other one. 

Mingi’s hole flutters around him, squeezing him impossibly tight, and San cums with his cock buried to the base inside him, pumping it all inside. Mingi gasps as he feels the human’s hot release flood his hole.

“Oh- oh, San…”

“I’m not done with you yet…” He mumbles, rubbing Mingi’s glowing red cheeks. They look so pretty like this, but there was more to be done. Mingi squirms around so much, humping his still-hard cock against the sheets until San’s cum starts to spill from his hole. San is displeased. 

“I told you not to touch yourself, did you forget?” He grips the demon’s hips and lifts them into the air again, using his fingers to stuff his cum back inside, “Or did you think fucking the bed didn’t count?”

Mingi whines at the human fingering him again, brain-gone, fucked dumb, tunnel-vision-focused on pleasure to the point that he doesn’t even hear what San says.

He really should be more careful.

San crooks his fingers. He taps the demon’s sweet spot a few times, and starts to rub the pads of his fingers against it, wildly abusing Mingi’s most sensitive parts until he’s satisfied with the thickness of the tears running down his face. Mingi cries so nicely, San doesn’t feel bad in the slightest when he edges him.

The demon wails in devastation as San ceases his movements and pulls away when Mingi’s body begins to tremble like it had the first time he’d cum.

“I keep warning you, and you keep ignoring me. You must really not want to cum!” He says starting the process over again, slipping three fingers inside and working them rapidly until Mingi’s thighs tense up, and this time, when he slips them out, Mingi finally seems to see the light.

“ F-fuck! Sannie, sir, please, please, I can’t take it, I n-need to cum… W-wanna cum on your cock, n-need you to touch me ‘n fuck me ‘n use me, fuck- I’ll really do a-anything…”

“Now you’ll do anything?” The human hisses, entirely unimpressed. “It’s so easy to tell how much of a spoiled princess you are, Minmin. You’ve hardly done any listening, and I let you cum once despite that, but you’re really gonna have to earn it now.”

“I c-can listen… I can, I can…”

“Get on your knees for me, then.”

Mingi whimpers and does as he’s told- albeit slowly, as his body still shakes and he clumsily stumbles over to sit on the towel San lays down on the floor. He doesn’t want to clean cum out of his carpet, but he’ll be damned if he lets the greedy demon plug his hole long enough to keep it from spilling. 

“No point in there being a gag reflex on you, so you’d better put some work in. I want to see your pretty lips around my cock and your hands on your thighs until I decide to fuck your mouth.” He orders firmly. The demon’s hands lay obediently on top of his thighs. 

Mingi clearly does not know his way around a cock. He looks at it and hesitantly opens his mouth to let his tongue slip out. Experimentally, he licks the tip, and opens up wider to suck to head into his mouth. San hisses as his cock quickly fills out again, eager to be sucked down Mingi’s throat. 

Mingi works it deeper, bobbing his head up and down at a slow pace as if he were savoring the flavor. His lips were wrapped around the center of his length, the tip at the back of his mouth and soon to sink deeper into the wet heat of his throat. His tongue glided against the underside of San’s cock, and the human grew impatient once more.

“Take it deeper.”

Mingi tries, squeezing his eyes shut and relaxing so that the length would slip deeper into his throat, causing the tears beginning to well up again to roll down his cheeks. His mouth opened wider as he sank down further until his lips were wrapped nearly at the base. 

“Move.”

The demon does so, lifting his head up and sinking back down. 

A few more tries proves that practice makes permanent, and once San decides Mingi’s not going to miraculously get any better at sucking dick, he grips the demon’s hair and takes the reins himself. 

Mingi is a sex demon… he should be fine.

“Put your hands on my thighs. Tap me three times.”

The demon takes hold of San’s thighs, his mouth still full of cock, and taps three times as he’s told. 

“Do that if you need me to stop.”

He nods as well as he can, and San begins thrusting.

If this is how they’re living in Hell… sign him up.

Mingi’s throat is glorious, wrapped perfectly around his cock and swallowing him down like it was meant for it. It may very well be, really. He sinks down to the base, tossing his head back and moaning as he fucks Mingi’s face with little care. 

Mingi, despite being the fussy little pillow princess that he is, takes it extremely well for his first time. It’s really a shame that he’s never tried before, San thinks for a moment. Then, he stops thinking.

“S-shit… Mingi…”

He’s close already, and as good as cumming down the demon’s throat sounds, he brings himself to pull the demon off his cock.

Mingi sucks in as much air as possible once he’s let go.

“Look at me.”

Mingi’s eyes meet his. His lips are wet and swollen, cheeks smeared with tears, and eyes bright and sparkly. San thinks that he’s earned mercy.

“Do you think you’ve earned it, princess?”

Mingi nods eagerly, his hands remaining in their place on San’s thighs. 

“Fine. Back where you were, up on your hands and knees.”

The human watches as he obeys.

Mingi initially lays on his stomach, but he allows San to adjust him. San grabs him by the hips and lifts his butt up into the air, still round, pretty, and red with his hand prints. This was San’s favorite way to see it.

The demon’s head is pressed against the bed still. San reaches down, gently tangling his fingers into Mingi’s hair. With his free hand, he takes his cock, strokes it a few times, and positions himself once more. The demon bites his lip as he’s filled.

“Th-thank you, thank you, sir…”

“So lovely, Minmin… You’re so good for me.” San will not admit that he’s out of it. He’s dizzy with pleasure as his cock is buried deep inside the tightest heat again. Mingi’s body heat, the softness of his skin, his delicious smell and lingering taste… If he was ruined for anyone else, he didn’t mind.

He fucks Mingi likes it’s the only thing his body was built to do. He pulls back slowly, and thrusts back inside all at once, hard and desperate. Mingi’s perfect ass meets his hips with a wet smack each time, punctuated by the pillowy moan that slips past his lips whenever the human strikes something deep inside him. 

Their moans fill the air, both rocking against the other, their skin glittery with sweat, and especially wet with natural lube and San’s own cum where their bodies connect.

They both chase their own orgasms, panting.

San then grips and pulls tight on Mingi’s hair, and whether by accident or not, it makes the demon’s back arch deep. San’s cock reaches deeper, mind-numbing spots inside his body, and Mingi screams.

“I-I’m cumming- oh, oh, please! Please, don’t stop, you’re gonna make me cum so hard, please-“

San’s ears might as well have been covered by muffs, but it didn’t matter. Mingi tightened up around him even harder, fluttering around him and milking him so fucking perfectly, no patience could ever allow him to stop now. 

“M-Mingi. I’m cumming, okay? I’m gonna fill you up and I want you to cum while I do it. Want you to cum for me, princess…” He panted out above the demon.

Mingi obeyed.

The moment he felt the human’s hot cum coat his walls and flood his insides again, he let go. His eyes rolled back, his body clenched up impossibly tight, and all the pressure built up in his core was finally released as he was fucked phenomenally into and through his orgasm.

“Fuck! F-fuck, Mingi… J-just like that. So good for me…”

San’s body connects with his back, laying still for a moment as he catches his breath. They’re wet and sticky, but his energy is drained and his vision is blurry. His cock is still hugged comfortably by Mingi’s hole, and Mingi himself is entirely soft and warm. Like a giant plushie. 

“…If you’re not finished, I c-can go as much as you want…”

San grins, and laughs, petting Mingi’s hair as he lifts himself up and finally pulls out. Goodness, this took it out of him. He hardly wanted to move.

“Not this time, princess... You were perfect for me, you know?” He says, cuddling up to the demon and wrapping Mingi into his arms as best as he can. Mingi nods with a satisfied smile. San noted that he liked compliments. “You’re my good little demon… And I think I’m going to get you cleaned up now, okay?”

The demon nods.

After a night with a human, he may be satiated, at the very least, but… This kind of deep satisfaction was doing something to him. Giving up control was so different. So new. The way he could have done these things for so long, and no one had ever wanted him this way before… He should have ignored his instinct a long time ago.

At least now, he knew. 

San leaves him there on the bed. It’s a mess. A horrible, horrible mess with slick and cum all over the place. San would have to get a new mattress as well, most likely. Mingi didn’t feel bad. In fact, he’s never felt this… good. So air-headed but perfect. He wanted to be in whatever state of mind this was for the rest of his long, long life.

Upon San’s return, the human looks down at his sheets and sighs lightly.

“I’ll have to go look for a new one tomorrow.” He notes out loud. For now, he reaches down and begins to clean Mingi with a damp towel. “This is just for now. You’re gonna take a shower in a minute, while I get these sheets up and throw some blankets over the couch.”

Mingi nods, lying still for San to clean him.

He has so many thoughts.

God, did he lose himself. He said so many things he never could have even imagined, and they felt so good to say. He loved every second of begging, every minute of being stuffed full, and even now he wanted more. He’d never even been aware before tonight that he produced slick. The towel is warm, and so are San’s hands as they trace his body. He sighs when the human slips the towel between his thighs. If he moves too much, he’ll lose more of the cum inside him.

He whines as his thighs are pushed apart- San pinches one, but not too hard.

The towel prods at his hole, wet and puffy, and still sensitive and desperate for more. He rut back against the towel and San’s hand underneath it.

Yes, he wanted more of this. Why did no human pleasure him this way? If his body could withstand this, why did his instinct fear it? That nagging in his gut… it was quiet now. Calm. Satiated along with the rest of him. 

Did that mean he would stay here? It wasn’t unheard of for a demon like-mind to humans to grow close to one, or even a select few. He’d never personally known any humans until now. He never harbored interest in one until San. 

Choi San, who’s odd ability he never did ask about…

“Ah… Sannie.”

“Hmm?” The man hums, still at work cleaning up the mess.

“You are human, aren't you?”

San laughs. When it didn’t annoy him, Mingi found the sound quite charming.

“I am. Are you asking why I can see demons?”

“Yes.”

“Well, put simply, it runs in my family.” San tells him. “My father could, and his father could, and his mother could, and her father, and so on. As for the reason why my family is like this… I’m not sure.”

Mingi listens closely. He’s never heard of a line of humans who knew they existed. He wondered if there was some sort of curse on them…Or if, distantly, San was a descendant of a demon himself. San did not seem to think so, or maybe he was just lying, but it would explain to Mingi how exactly this human had so much power over him.

It seems he’s given up with the towel, likely because the demon has yet to stop producing slick and fighting it was a losing battle at that point. He sighs, carrying it back to the bathroom, returning a moment later.

Mingi still lies down on the bed, watching as San opens drawers and pulls out clothing. Surely too much for just one person to sleep in.

Aw. He was putting Mingi back in clothes already?

“Don’t whine. It's cold these days, you should wear these while you sleep.”

Okay, Mingi might have whined a little bit.

At least, it seemed like San wanted him to stay. When humans stayed together through the night, what did they do? Sleep, right? Would there be enough room for both him and San on the couch?

“Come here, Minmin. Let's start your shower now.”

It takes some time, but San manages to get the demon into the shower. 

Mingi stumbles out of the bathroom awkwardly, wearing the shirt he was given backwards, and clearly not wearing the underwear San had given him, as they are still in the bathroom.

San chuckles. He’s already tossed the sheets in the washing machine, hoping the damage isn’t too bad, or that his other options weren’t too expensive. It wasn’t too big of a loss. Really, a small price to pay for the possibility of another night with this blessing from Hell.

San has the demon rest on the couch while he takes his own shower. It’s rushed, as the warm water gently stimulates his already spent body.

He couldn’t believe Mingi offered more after those rounds. San had never orgasmed more than three times in a row before, and didn’t even last so long tonight, but Mingi required more attention than his own stamina allowed.

Maybe he was just out of practice?

It didn’t matter so much as of now. He hopped out of the bathroom and into the living room, where he found the demon attempting to understand how to use a blanket.

“Ah… Mingi. It goes on top of you… But, I guess you could also use it that way?” The demon has wrapped himself into a burrito, as tight as he possibly could. It looked like he assumed a blanket was… like a trap, meant to be tight and inescapable. If that was the case, then he succeeded, as he needed the human’s help to get out of it.

Mingi rolls off of the couch and onto the floor. He pouts when San giggles at him. The human should not enjoy his suffering.

Either way, he allows San to sit on the couch, and take the demon into his arms.

Mingi perks up.

“More, now?”

“Hmm?”

“You’re touching me again.”

“Yes, I’m cuddling you.”

Mingi has heard that word before.

Sounds sexy.

“Mingi- Mingi, no. You just showered. Why are you rubbing again-“ San struggles to get Mingi under control for a solid 15 minutes.

What he discovers in that time is that the demon severely missed the point of non-sexual physical contact.

“Non… What?”

“It’s like… hugs. Snuggles? You don’t do those, Minmin?”

“…Of course I have.”

San did not know why he expected a straight answer. He could tell Mingi had done no such thing.

“It’s just a way of being affectionate, baby. I give you hugs and cuddles because I like you and I like being close to you, and that may not always mean more sex.”

Some more explaining. A few more examples. But eventually, Mingi understands.

And thank Hell for that. He soon had the demon in his lap, resting his head on San’s shoulder with his arms around him as well. He rubs comforting circles in Mingi’s back. It might be these things the demon does not understand that makes the human feel this way. He didn’t often consider spending extended periods of time with flings.

But of course, Mingi was something entirely different.

He did learn a new thing while the demon showered, which was that the demon’s mess didn't become cold with time. Even what had coated the bed at least an hour ago was still warm to the touch. 

In fact, some of it had disappeared, he thought. Into thin air like it was never there. He made a note to ask the demon if he’d experienced such a thing before. As for now, Mingi seemed quite comfortable in his arms.

Whether or not a demon needed sleep, he was sure that even they could use some closeness from time to time.
