Chapter Text
Chan was determined to pass his summoning class if it was the last thing he did.
What he wasn’t expecting was to summon an incubus…or succubus..?
[sex demon Jeongin! X dark mage Chan!]
---
Waking up to a pretty face sucking his dick was always a pleasant sight.
Looking down Chan let out a groan at how pretty Jeongin looked as he worked his way down his cock, his length making the smaller’s throat bulge obscenely due to the sheer monstrous size of his dick.
Carding his fingers through the smaller’s hair, Chan felt himself almost lose it at the sight of Jeongin’s eyes fluttering up to look at him. Pretty blue eyes, shining with unshed tears as he continued to thoroughly work his mouth and throat on Chan’s dick.
“...fuck cumming baby…” Was all the warning Chan gave Jeongin before he felt himself cum down the other’s throat, the small demon giddily sucking at his dick in order to slurp up all of his semen. Only pulling off when Chan pushed him away by his shoulders as oversensitivity started to set in.
“Morning Master! Did Innie do good?” Jeongin asked, the small heart tipped tail flicking back and forth behind him excitedly.
“You did great, baby, now let’s get ready for class ok?” Chan prompted as he moved to get out of bed. Jeongin following closely behind.
Once dressed, Chan motioned for Jeongin to stand in front of him so he could properly get the small sex demon ready for the day.
“Now remember baby you have to behave ok?” Chan said as he grabbed the essentials from his closet, setting them down onto the bed before he faced Jeongin.
“I know Master. I promise I will! So does Innie really have to wear the belt still?” Jeongin asked while giving Chan the biggest puppy dog eyes he could muster.
“Yes, yes you do. Now come here.” Chan said as he helped Jeongin step into the chastity belt, ignoring the sex demons grumbles of disagreement as he pulled the belt up his legs, making sure to gently ease the toy into Jeongin’s sopping cunt, shimming the belt around till the hook attachment in the front was perfectly settled onto Jeongin’s clit.
Once the toys were in the proper position, Chan tightened the straps around Jeongin’s waist making sure that the small demon wouldn’t be able to move anything he meticulously placed. Once secure, Chan made sure to lock the belt in place with a quick spell, which created a pretty glowing mark to be shown on the front of the belt.
“Until I can ensure that you’re not going to go around and suck the life essence out of the school body, you’re going to be wearing this when we go out ok?” Chan said sternly.
“Ughhh…fine…” Jeongin petulantly said, with a pout on his face.
“Good, now get dressed or else we’re going to be late.
---
Now if you told Chan a month ago that he’d be “in charge” of a cutesy eccentric incubus, or succubus, Chan still wasn’t sure about that one, Chan would definitely laugh in your face.
Not even once in his twenty something odd years of life did Chan think he’d be the so-called “owner” of a sex demon, yet here he is walking down the halls of his university on his way to his “Spell Etymology”, with a cutesy pink haired demon pouting next to him, but obediently following him to his next class.
Cute face flushed a pretty pink while his tail was flickering behind him like some cat that was about to pounce on his prey.
Which was the exact reason for the chastity belt that Chan locked him in before they left his apartment.
The chastity belt cost an arm and a leg to have someone make, however it made sure that Jeongin had no way of unlocking it, and it also made sure to punish the sex demon whenever he tried to take someone’s life essence that wasn’t Chan’s. Now did Chan do that because he actually gave a shit about the other innocent people that were just trying to go along with their lives? No, he did it more because he wanted the pretty little demon to be solely reliant on him and him alone.
Call him possessive sure, but how could he not be when he had one of the most beautiful creatures by his side.
The pretty sultry fox eyes, high cheekbones, pouty lips, slutty little waist, plump ass, and even more delicious and divine cunt. All for him.
And him alone.

“Come on Master~ Please~ Innie’s been good?” Jeongin asked, giving Chan his signature puppy dog eyes as he was straddling his lap, hands going to pull at the waistband of Chan’s black skinny jeans.
Sighing, Chan gave Jeongin a reprimanding look, “Innie, baby we only have to be on campus for another two hours, can you wait till then?” Chan asked, face pulled tight in displeasure, easily moving the demon’s hands away from his pants. Eyes sending glares towards the students nearby that were looking a little too long at his precious baby’s ass.
“B-but please Master~? Please, Innie’s cunt feels empty.” Jeongin whine, catching the attention of multiple students at how loud the whine was and how obscene the words were.
“Hmmm…Like I said there’s two more hours before we have to leave, now Innie can be a good baby for his Master right?” Chan said again, tone cold eyes now glaring at Jeongin who just whimpered in return before moving to sit next to Chan instead of on his lap.
“Good, now be a good boy and play with your toys while your master works ok?” Chan said, which made Jeongin’s head shoot up and frantically shake in disagreement.
Ignoring the demon’s displeasure, Chan waved his hand on top of Jeonging’s crotch which made Jeongin tense before his back broke into an arch as the toy that was resting inside of him twirled to life, wildly moving inside of him while the little hook that was perfectly situated to be gently pressing into his clit started to madly vibrate making his body twitch in pleasure.
Face flushed pink, Jeongin tried his best to keep his composure, knowing that if he came now there would be no stopping which meant he had to deal with the pleasurable torture of overstimulation. His own slick and fluids were already leaking through his own pair of slacks and dirtying the seat he was sitting in. Clawing at the table, Jeongin rested his head against the cool surface as he tried his hardest to deal with the pleasure coursing through his body, hips jolting and flinching from the overwhelming pleasure.
Seeing his little demon whimpering and sobbing in pleasure while he worked on his Magical Essence Logistics homework made Chan smirk. Knowing how hard his little pleasure pet was trying to not to cum made something dark and twisted rise in his chest.
Making another subtle movement with his hand, Chan tried his best to not let his amusement show through his features at the loud wail Jeongin wasn’t able to keep in as his body caved forward the notable sound of liquids squirting onto the floor was audible for everyone in the nearby vicinity in the otherwise quiet library. Looking over to his baby, Chan licked his lips at how debauched the other was, eyes glazed over as tears fell freely from them down onto the table, one of Jeongin’s hands was still clawing at the table top while the other one was desperately trying to claw the belt off of his hips. His whole form was trembling in what Chan could without a doubt guess to be overstimulation as he made sure that the belt was working overtime on the sex demon’s sensitive cunt.
Pulling his attention back onto his logistics homework, Chan tuned out Jeongin’s wails and sobs as he continued to work through the given problem set, only making sure to note to give the small demon a reward later once they got back to the apartment after the ordeal he was forcing the other through.
Jeongin felt as though his body was on fire, he already came once, his release squirting violently from his cunt and onto the library floor. His juices now gushing out of the seams of the belt as his master was cruel and didn’t bother to turn the mechanism off. Which resulted in his body going into pleasure overload. His own demon anatomy making him naturally more submissive, Jeongin felt himself fall into a pleasant haze filled with pleasure. Completely unaware of the overly lewd expression that was decorating his face as he felt his cunt clench harshly around the toy that was currently stroking his insides. The head of the toy was curved so that no matter what Jeongin did the head of the toy would run constantly against his sweet spot as it twirled around inside of him. The pleasure he felt from his clit was completely tortuous at this point in time as it worked relentlessly against it. The sensation from the vibrations wavering just on the line between too much and not enough.
Lazily looking towards his master, Jeongin let out a long drawn out whine when he was finally able to see that Chan wasn’t paying any mind to him, not even a whiff of arousal was coming off of the man which was making Jeongin feel overly frustrated in return. With one hand still desperately clawing at the belt in the hopes of prying the damned thing off, Jeongin sat there pitifully whimpering as he felt his body slowly creep towards his next orgasm.
“P-please~ m-muh-master~”
“Hush pet. Keep distracting me and we’re going to be here even longer.” Was all Chan said, sighing in faux annoyance at Jeongin’s whimpering form. Deciding not to be too mean, Chan reached out and pulled Jeongin own clamering hand into his own, allowing the demon to clench it whenever he felt like the sensations in his cunt were too much.
Resigning his fate, Jeongin sat there whimpering next to his master while he felt himself go in and out of the pleasurable haze that was over taking his senses. With one hand desperately clawing at his master’s own hand to try and ground himself front he overwhelming pleasure, and his other hand still clawing at the damned belt, Jeonging sat there as quiet as he could, not wanting to have to stay in the god forsaken library longer than necessary. Only the occasional whimper escaped his mouth whenever he surrendered to the pleasure and conceded to the damned belt, his release salaciously splashing against the library floors, slowly starting to create a small puddle underneath him from how much he was releasing.
---
Chan was proud of his little pet if he had to be honest. He honestly wasn’t expecting Jeongin to last ten minutes, let alone the full two hours. But here they were, Jeongin still hazedly moaning as his cunt squirted out his release almost like a fountain. The demon’s normally blue eyes now a pretty rosy pink color along with his tail that was now whipping back and forth wildly behind him. Deciding to be merciful and also knowing what the pink signified, Chan waved his hand which turned off the machines that were working away at Jeongin’s cunt. The incubus weakly collapsing onto the table in relief.
Seeing the demon’s weak form, Chan stood up and moved to pick Jeongin up into his arms as he made his way out of the library.
“...w…w-was good master..?” Jeongin asked dopily, completely pleasure drunk from the ordeal that Chan put him through.
“You were baby. So perfect for me, my lovely little pet. Now we’re going to go home so I can give you your reward.” Chan said as he merrily walked out of the library, citing a quick spell from under his breath to clean up the mess that Jeongin made.
One because his little baby squirted out a lot of cum during the two hours of being forced to deal with the constant pleasure attacking his poor cunt.
Two because incubus, or succubus, Chan still wasn’t sure what Jeongin counted as, cum had some less than desirable effects to some. And Chan did not want to be the one responsible for the outcome of that.
---
Throwing Jeongin onto the bed, Chan made quick work of wiggling the sex demon out of the belt in order to reveal the other’s pretty, puffy, pink cunt. The toys that were attached to the belt were drenched and dripping in Jeongin’s release, the clear slick dripping out of the demon’s cunt made Chan want to hold him down and lick it all up, forcing him to cum again and again on his tongue.
But this was a reward, not fun time…well…
Shaking his head, Chan quickly removed his own pants, his own monstrous dick hard and erect, slapping against his abs once he was able to rid his pants off of himself. Stroking his dick to wet it with his own pre-cum, Chan looked down at Jeongin who was still dazedly looking up at him.
“Such a good baby all day…deserves a nice reward hmmm…” Chan said as he sat back on his heels and pulled Jeongin down by his hips, moving so his plush ass was now resting on top of his thighs.
Reaching down, Chan positioned his dick so that the tip of it was pressing into Jeongin’s cunt. The small little slit widening to make some room for the large appendage.
“Such a good pet.” Chan said, finishing his sentence by slamming his cock the whole way into Jeongin’s smaller body, the incubus backing snapping into a high arch at the feeling, cum squirting out of him from the harsh intrusion and wetting both Chan’s pelvis and the sheets below him, a loud wail being forced out from him at the action.
“Aww, already baby, but your master didn’t even cum yet. What to do…” Chan teased as he continued to grind his large cock into Jeongin’s tiny cunt, groaning when he saw the small indentation on Jeongin’s lower stomach move in time with his hips.
Hearing this made Jeongin frantically shake his head as he started to plead for Chan’s cum the best he could as he was sobbing from the sheer amount of pleasure Chan was giving him.
“N-no pl-please, master-ah-please, wan-wan-wann cu-cu-cumm…” Jeongin weakly pleaded, head starting to rise to the same pleasurable hazy place that it got to whenever Chan fucked him thoroughly enough.
“Hmmm…if you insist.” Was all the warning Jeongin got before he was forced onto his front, Chan’s cock leaving him for a brief moment due to the action, only to be roughly punched back into him, making him wail at the harsh feeling, head hanging heavily in between his arms as he felt his upper body go weak from pleasure.
Seeing how debauched the sex demon was just drove Chan that much harder to try and ruin him. Quickly and harshly pistoning his hips into the smaller, Chan moved until he fully covered the smaller’s body, one hand squeezing Jeongin’s small waist while the other one was holding him down by the neck to ensure that he couldn’t try and fight the pleasure he was giving him. Smirking when he felt a gush of warm slick hit his thighs again.
Keeping up his relentless pace, Chan continued to plow his cock into Jeongin, the hand that was originally squeezing his waist now moving to feel the bulge his dick created on Jeongin’s stomach. A sick pleasurable feeling twisted inside of him when he felt how violent his thrust were from this, moving to press down against the indentation, Chan groaned into Jeongin’s ear when he could feel his own administrations through Jeongin.
“So tiny baby. Can feel myself though your tummy.” Was all that Chan said, making Jeongin whine out loud, head too cloudy to come up with a proper response.
“Feeling good baby? That was what, the sixth time you’ve squirted on me?” Chan asked, teasing the small sex demon as his hand that was playing Jeongin’s tummy bulge moved lower and lower till it was rubbing against the small bud that gave the smaller so much pleasure. The action making Jeongin yell out at the overwhelming and borderline painful feeling.
Wanting an answer Chan teased again, “Come on baby, your master asked you a question and I want an answer.” Chan said simply as he moved his body up so he was now longer smothering Jeongin into the sheets, moving the hand that was clasped around Jeongin’s neck, Chan sat back and pulled Jeongin up by his hair, the sight of the other’s face almost making Chan bust on the spot.
The demon’s eyes were half-lidded and hazy, tears flowing from his pretty pink orbs, and eyebrows arched in pleasure. Face flushed a pretty pink and mouth gaped open with pleasure as drool steadily made its way out and dirtied the sheets.
Jeongin looked absolutely debauched and cock drunk.
Growling at the sight, Chan let go of the other’s hair and moved to hold Jeongin up by his arms, using them as a way to get leverage in order to pound into Jeongin harder, the demon letting out the sluttiest and dirtiest moans at the action, Eyes going crossed in pleasure, Jeongin was barely aware of how debauched he looked as all he could feel was Chan’s wondrous cock plow at his insides and run against his g-spot again and again in a ruthless manner. With no regard to his own well being, Jeongin felt as though he was getting thoroughly used. The mage’s stamina and ability to ruin him was even better than the demons he’s fraternized with down in hell.
His dick was godly and monstrous as it continued to plow at punch at his insides, going as far as to carve its way into his womb, the feeling so overwhelming and pleasurable that all Jeongin could do is choke out moans and whimpers at the feeling. Feeling as though his body was no longer his own, Jeongin succumbed to the pleasure Chan was forcing upon him.
Seeing how gone the demon was made Chan groan, a flash of worry coursed through him briefly before he waved it away, already knowing what would happen if he stopped now. Rolling over, Chan pulled Jeongin onto his lap, the smaller’s back leaning heavily against his chest as his hips continued to plow up into the smaller’s cunt. Jeongin’s back arched in pleasure as this position forced Chan’s cock to dig even further into him. The feeling was so intense that Jeongin thought that if he tried hard enough that he could probably taste Chan in the back of his throat if he tried hard enough. Chan holding him against his chest by the tight grip in his hair, Jeongin resigned himself to be the other’s ragdoll as he continued to plow at his insides. His cunt pulsing and clenching around the other’s length at the overwhelming pleasure, his insides and demon anatomy trying it’s hardest to milk the mage of his cum.
“Fuck, I can feel you trying to milk me. Baby’s getting desperate huh..?” Chan teased, free hand moving to pick and pinch at the other’s nipples, internally grinning at the whimper the other let out at the action.
“Don’t worry pet, master promised to give you a reward hmm..?’ Chan said as he could feel the tell tale signs of his own release coming.
Abs clenched and balls drawing up towards his body, Chan continued to punch his cock up into the smaller, ignoring the mess of slick and cum that was continuing to gush out of the smaller’s cunt. Chan kept plowing his cock up into the sticky and slick mess, dick twitching more and more as he felt himself get closer and closer to release.
“Fuck, gonna cum, you want my cum don’t you pet.” Chan groaned hotly into Jeongin ear making the incubus moan in agreement as his cunt harshly clenched around Chan’s length.
Dryly chuckling, Chan stopped his harsh thrust to instead grind his cock up into Jeongin’s cunt, the action making Jeongin sob at the intense feeling and pressure against his sweet spots, his cunt clenching erratically at the feeling, making Chan groan in return. Hips kicking up a few more times, Chan leaned down and bit harshly into the junction of the demon’s neck as he rutted his hips up to ride out his orgasm.
The feeling of his master cumming into his cunt felt euphoric, the dark essence coming from the dark mage was intoxicatingly delicious. Continuing to clench his cunt around the other’s length, Jeongin purred in delight as he felt the other’s magical essence flow through his body.
Unclenching his jaw from the demon’s neck, Chan groaned at the taste of the other’s crimson blood flowing into his mouth, the sweet flavoring filling his own body with the hellish essence that incubus was created from, made Chan groan in delight. Sighing, Chan slowly started to ease his cock out of the other’s spent cunt. The action making Jeongin whimper as he felt the other’s soft length rub against his walls harshly due to the sheer size of the other. Once his dick was finally out of the other, Chan gently placed Jeongin down onto the bed, cussing at the sight that was laying before him.
Jeongin laid spread out in front of him, legs bowed out in exhaustion, showcasing his cute puffy cunt to anyone and everyone. His nipples were a bright red from all the teasing and torture they went through from Chan, bruises were already starting to form on his hips and neck from Chan’s rough grip. His cunt was pink and puffy, his juices leaking out of him like a broken faucet while Chan’s cum was being securely held in Jeongin’s womb, his demon anatomy storing the essence for later use. The smaller’s clit was engorged and red, still erect and peeking out from under its protective hood.
Leaning down, Chan couldn’t stop himself and wrapped his lips around the cute red bud, the action making Jeongin’s back break into a violent arch while his eyes shot open, hands frantically trying to pull Chan off of one of his most sensitive spots.
“P-please, can’t t-too m-much”
“Come on baby, just one more you can do that for your master right?” Chan said, lifting his head off of the bud for a brief moment before diving back down to start to suck and lick at the small bud, completely obsessed with the angelic moans and sobs coming from the demon that was thrashing in pleasure above him.
Jeongin felt insane, liquid magma taking over all of his senses, leaving any working thought in his head to jumble about and turn into an incoherent pile of gush. Hips twitching in Chan’s strong hold, he had no choice besides to take what the other was forcing upon him as every time he tried to either claw the other’s head away from his poor cunt he had no luck, and with how much stronger Chan was over him, there was no way in hell that he was going to be able to get out of the muscular mage’s hold.
Feeling all of his senses short circuit at once, Jeongin laid there boneless as Chan worked him towards another orgasm. The warm and electric feeling slowly bubbling inside of him, Jeongin laid there sobbing as Chan’s administrations were unrelenting.
Smirking, Chan continued to lick, suck, and lightly nibble on the small erect clit, determined to keep going until Jeongin came again. He could feel the other’s slick drenching his chin and dripping onto his neck but Chan didn’t care all he wanted was to drive the incubus insane with pleasure and he wasn’t going to stop till the other was crying at him to stop.
Alternating between flicking his tongue over the bud and sucking the bud in between his lips, Chan continued to torture the small bud, only taking a moment or two to move his way down to drink up some of the incubus’ delicious slick that was still leaking out of him, hands pinning the demon’s hips down, Chan made sure he had now way to escape his administrations.
“P-ple- g-guh-nnn c-c-cummm…” Jeongin weakly called out, already teetering on the edge of passing out as he felt so overwhelmed with pleasure that he wasn’t sure how to handle it.
Hearing this spurred Chan to double his actions, working harder and rougher, Chan continued to suck and nibble on the other’s clit till he heard the demon let out a scream in pleasure as stream of slick harshly squirted out of him, Chan doing his best to catch the release in his mouth as Jeongin’s hips undulated in pleasure, his mouth chasing the release like a hungry dog as he surged forward when the stream died down to clean up whatever slick was dirting the other’s thighs.
Once done, Chan looked up and let out a curse.
“...fuck, didn’t mean to make him pass out.”
