Set within my other story, Hell Born. It exists completely in a vacuum and all you need to know is that San is a demon.

≫ ──── ≪•◦ ❈ ◦•≫ ──── ≪

Realistically, most would be afraid to start a relationship with a demon. Let alone be near one. Yet it was never something that turned Wooyoung away. San was sweet and one of the most caring people he had ever met. Though he had his moments of less than favourable tendencies, Wooyoung didn't care. He adored his boyfriend, demon or otherwise.

For the most part, San was rather soft. He would never do anything to hurt Wooyoung and if he did do anything that may irritate him remotely, he would break out in a fit of apologies.

So it isn't much surprise that Wooyoung's often the one praying for some sort of attention. Of course, San was always willing to cuddle, but that wasn't what Wooyoung wanted. He craved intimacy, to be touched and loved by his boyfriend. Yet San was always too afraid to do anything like that.

Though, that didn't mean San didn't have needs as well.

It was late in the day, around half past four, and Wooyoung was sitting at the desk in his room. He would sit in San's but he had been acting clingy and knew he wouldn't get much homework done if he stayed in there. The teen twirled his cherry lollipop in his mouth, pondering over the set of math equations in front of him. "Useless things..." He thought to himself, bitterly clutching his pen in his right hand while glaring at the paper.

The boy was too busy grumbling under his breath to notice his door slowly slide open. However, his attention was quickly driven away when he felt a pair of arms snake around his neck. Wooyoung's surprise melted into delight when he realised who it was. "Sannie~" He whined playfully. "I told you I had a lot of homework to get done."

"I know," The demon replied, stretching the syllables of his words in a somewhat whiny tone. "But I missed you."

"It's only been twenty minutes," Chuckled Wooyoung. "You couldn't have missed me that much."

"You'd be surprised," Was the demon's low response. His tone alone managed to send shivers down the younger males spine. Wooyoung knew all too well what he wanted.

"San, I'm busy." He heard the demon hum, hands roaming his chest while his face lay just beside Wooyoung's. He swore he would've melted right then and there from his touch. His hands felt so warm and his scent was just so intoxicating. He wanted nothing more than to let San do as he pleased with him. However, he was determined to stay firm in his stance. "No." He stated simply, the single word startling San.

"No?" He repeated in disbelief. "But..."

"No, San. I've got homework to do. Maybe later, okay?" Now normally, that would be the end of it. San would leave the room, albeit a little moody, and Wooyoung would get on with things. Today though, the demon wasn't in his usual mood.

He crouched to his knees and rested his head on the human's thigh. "Wooyoungie~" The younger rose his brow at the way he whined, looking up at him with his big eyes. His heart churned at such a sight and he would be insane to deny him now.

So, Wooyoung sighed, gently taking the demon's face into his hand and stroking his soft cheek. "So needy today~ What do you want, Sannie?"

"You, I want you, Woo." That surprised the younger. Though he supposed he shouldn't be so shocked based on the state the demon had slipped into. It's just that usually, San was on top. Seems today may be the exception. Yet something about that made him smirk.

"Alright then Sannie, I'll treat you well. Don't worry. Strip for me." San understood exactly what he meant and slipped out of his shirt. He kept his eyes on Wooyoung, eyeing his every movement while they undid their clothes. The demon would never get tired of seeing his boyfriend's perfect curves of his plump ass, always begging to be grabbed.

That would have to wait for later though, as San had sat himself on the bed, awaiting Wooyoung's next move.

What started as a gentle peck on the lips gradually fell into a messy battle for dominance that the demon easily won. San pushed his tongue past the soft barriers of Wooyoung's mouth, savouring the sweet taste of cherry from his sugary treat. The blonde couldn't help but moan into the kiss, soon whining when his lover trailed to his neck. "Mm, Sannie~"

"You like that baby?" He chuckled against the younger's skin when a light gasp left him. The sound alone made Wooyoung grow flushed.

"I thought I was supposed to take care of you. What happened?" The almost pout San received made him laugh once again. With a shrug, he shifted to spread his legs, Wooyoung quickly catching on.

The blonde licked his lips at the sight of his member, sprung up proud, nearly salivating at it. "All for me~"

"Woo~ Hurry up! I don't wanna w- hng!" The warm feeling of Wooyoung's mouth engulfing his length zipped his lips within seconds, becoming weak the moment they made contact. "Oh fuck Wooyoung..."

The younger's tongue slid across the base of his dick, eliciting a moan of euphoria from his boyfriend. San's hand found its way into Wooyoung's blonde locks, gripping them with every suck. He found himself wincing at how hard he would pull but didn't have it in him to care. Not when he knew he was making his lover feel this good.

Fuck, he's so sensitive.

Wooyoung could feel the demon's member twitch in his mouth yet continued to suck, regardless of how much he gagged. Even still, he didn't want to see San cum just yet.

"Ah~ W-Wooyoung..."

Wooyoung detached with a light pop, plush lips glistening with the precome dripping from San's tip. The smile on his face was innocent despite this, as he tilted his head to the side in an almost taunting manner. "What's wrong Sannie? Want me to stop?"

The way the demon shook his head made Wooyoung smirk. It was entertaining how much power he held over someone who could destroy the city if he so desired. Yet here he was, panting and pleading for this human's every touch.

It was delightful.

Kisses peppered San's waistband, each lustful touch causing him to arch his back as he whined for more. These simple prods had him withering with impatience but more apparently, neediness.

He felt the way Wooyoung pinched folds of his skin between his teeth, sucking and licking every spot to leave a beautiful bruise for tomorrow.

San's cock, neglected and begging for touch, thrived on every action, sending shivers of pleasure down the demon's spine. He needed more.

"Wooyoungie~ Please~"

"Please what, Sannie?" Wooyoung replied, head now resting on the mattress. His sudden distance seemed to make San stressed, fearing he may be left like this - hot and unsatisfied.

"I need more~"

A thoughtful hum came from the younger. San tensed when he finally felt a hand wrap around his girth. The strokes were slow, painfully slow. "My Sannie is so needy, isn't he?" San nodded once more, whispering under his breath for Wooyoung to go faster.

He didn't. In fact, he went even slower, stopping almost entirely until he got an answer. "Y-Yes! I'm needy!"

Finally, Wooyoung giggled. He kept moving his hand up and down his boyfriend's length while he travelled to his neck. San couldn't help but moan from the vast amount of pleasure as he was jerked and as more hickeys were plastered on his body.

"Sannie is so sensitive too, isn't he?"

"Yes, S-S..." he bit his bottom lip, refusing to submit entirely. Yet this refusal made Wooyoung halt all action.

San hated being teased. He didn't like having to wait to get what he wanted and it took every ounce of restraint he had to keep himself from taking over Wooyoung's mind and making him continue.

Yet the pure look of apathy he received, caused something to shift in him. It was clear Wooyoung knew he wouldn't last. When the demon began to sniff, light tears of frustration running down his cheeks, the blonde smirked.

"So greedy. Sannie is so desperate for me, isn't he?"

"Yes!" He finally wailed. "Sannie is greedy! Sannie wants Wooyoungie to touch him so badly!" Those words alone were enough to have Wooyoung smash their lips together, barely giving him a moment to breathe.

San gasped at the way his cock was pulled, jerked at a speed that made him whimper. "Wooyoungie~" he moaned, earning nothing but another smirk from the younger.

"Does Sannie like this? Does he like it when I handle him this way?" The demon could only groan in response, fist clenching around the fabrics of the sheets to distract himself from the immense pleasure. "Cutie~ Sannie has so much power but is so weak for me."

"P-Please let Sannie cum! Please please please!"

"What a mess you're making," he softly scolded, ignoring the demon's request. Such a thing made San quiver. He pleaded for Wooyoung to let him cum but the other refused to acknowledge it.

All that pressure came piling over when the demon released in Wooyoung's hand. And though San sighed with relief, his boyfriend was less than pleased. "Did I say you could cum?"

"N-No but..."

"But nothing. That was very bad Sannie." The demon looked down, as if he were a puppy being scolded by his owner. Even with his adorable expression, Wooyoung didn't let up, despite how much he wanted to shower the older in kisses and praise. "Now I have to punish you."

If San wasn't whimpering before, he certainly was now. Wooyoung crawled over him, leaning over the taller and grinning at his lost expression. He hovered his rear just over the demon's length, lining it perfectly. "W-Woo..."

"Shhh, relax puppy." Sinking onto his member, Wooyoung hissed under his breath. Perhaps he should've prepped first. The pain would fade soon enough. He started slow, bouncing only slightly which still elicited light moans from the older, who felt Wooyoung clench around him.

However, Wooyoung slowed down when San pressed his face against his bare chest, hearing him sniffle. "What's wrong, Sannie?"

"N-Not ready. Please go slow..." Wooyoung had to remind himself that this was meant to be a punishment. Yet San's light cries made him soft.

"Okay Sannie, I'll let you adjust first." After all, it was the first time he had ever ridden the demon before. Even with their close contact, San craved more. His lips parted, insinuating their desire for attention. Attention Wooyoung gratefully gave him. Tongue pushing the plush barriers and snaking into the wet cavern of his lover's mouth. San sighed into the kiss, hands moving towards Wooyoung's waist. Knowing he was happily distracted, the blonde resumed his movements.

He broke their kiss to gasp, eyes clamping shut from pleasure. "Oh Sannie~" He groaned out. Instinctively, the demon's hand travelled to Wooyoung's ass, gripping and kneading the soft flesh to his content. Yet he was stopped when his arms were pushed back. "Punishment, remember?" The blonde rasped out. "No touching."

"Wooyoungie~"

This time, he wouldn't go soft. "No touching," He repeated, tone much more commanding this time. "And don't cum until I say so."

Begrudgingly, San did what he was told. Keeping his hands to the side while Wooyoung bounced on his cock. The demon mewled beneath him, fueling the human to go faster. And though he moaned and groaned with every move, it couldn't compare to the weak pants of San, who kept as still as possible.

He wanted to touch Wooyoung. He wanted to kiss him. He wanted to hold him and smother him with affection. Wooyoung could see his restraint clearly, as the demon's eyes brightened with their usual purple colour. So he made sure to praise him, just to make sure he wouldn't become too frustrated.

"What a good boy you are Sannie, listening so well."

"I-Is Sannie doing good?" Peeped the demon, interrupted by his own strained breaths.

"So good, baby."

"Can Sannie get a kiss? Please!"

"Not yet," A part of Wooyoung felt like being a brat. He knew he shouldn't keep edging him on like this but he just couldn't help it. He adored how submissive San would become for him. He relished in the idea that he had power over a demon. The thought alone had him aroused beyond belief.

It wasn't long, however, before Wooyoung was reminded who had the real power here. Wooyoung gasped when a hand engulfed his neck, snatching him lower. He winced at the way San's eyes glowed violently, his grip becoming tighter by the second.

The way he gagged had the demon grinning until he brought their lips together. Though Wooyoung was too shocked to even consider kissing back, their contact seemed to relax San enough to where he let go of his neck.

"No more teasing," He whispered.

Wooyoung nodded at him, hand slowly tracing his disturbed neck, as it began to sting ever so slightly. He looked to his boyfriend, expecting him to take control and slowly attempted to move. Yet San kept his hips firm, much to Wooyoung's bewilderment. "Please don't stop," He pleaded in a small voice. The kind Wooyoung knew he only used when he was a sub.

"You scared me for a moment, puppy." Said the blonde with a weak chuckle.

"Sannie is sorry, Sannie is sorry! Sannie didn't mean it! Please forgive him!"

Ultimately, Wooyoung cooed at his weak and adorable state, placing a gentle kiss on his forehead. "It's alright Sannie," He said softly. San giggled when he received yet another kiss. However, his smile fell at what Wooyoung said next. "But Sannie doesn't get to cum again."

"W-What?"

"You heard me. On your knees." San obeyed and turned around, perky ass awaiting whatever Wooyoung had in store. He could hear the sound of a bottle of lube opening, where he kept it, San didn't know; following the cold substance dripping onto his rear. Wooyoung chuckled at the way he flinched while he coated his fingers.

Even though he wiggled in discomfort, San soon adjusted to the way Woo's fingers moved in and out of him, bringing forth a cry of thrill from him. He scissored his digits, stretching San to where he thought he was necessary. The demon, however, was feeling impatient.

"T-That's enough. Need something bigger~" Wooyoung slowly removed his fingers, carefully replacing them with his member a moment later, per his boyfriend's request. San withered at the new area of length intruding on his hole, with Wooyoung grunting above, murmuring about how tight he was.

The cold, slick feeling of the lube allowed him the room to shift and after a few seconds for them to both adjust, San permitted for the blonde to move. With great care, his hips began to rock forward, eliciting whines from the demon within seconds.

"Woo~" He moaned. "Faster." The younger grinned and picked up his pace almost immediately. Each time, he nearly drew out and railed into him at a quicker speed, smirking at the way San cried out in pleasure. His head fell, body jolting at every movement while his eyes fogged with tears.

"Aww~ Poor baby. Sannie just couldn't wait, could he?" Muttered Wooyoung from above, voice both taunting and sympathetic for the demon. Though it was mostly meant to jeer to the older, as Wooyoung groaned at the building shame in his posture.

"N-No, Sannie couldn't wait," Whimpered the older. "Sannie is needy for Wooyoungie." His deep moans and whiny pants were music to Wooyoung's ears, the only incentive he needed to go faster. "Mmph Wooyoung!"

This time, he laughed. "Your little hole takes me so well puppy~ So good for me."

San's pants grew uneven, moans becoming higher by the second.

"Aw baby, what's wrong?" San didn't respond. The demon kept his head down, biting his bottom lip to hide the exasperated breaths escaping them. Wooyoung could see his legs quiver and it didn't take long for him to realise why. "Sannie wants to cum again, doesn't he?"

San nodded eagerly, tears of frustration running down his cheeks from being just a few seconds from release. He didn't want another punishment and waited with weary patience. "Go ahead then, Sannie. Cum for me." The demon did as he was instructed, a loud moan escaping him as a copious amount of slick dripped from his tip to his leg.

He sighed with satisfaction, yet winced when he realised that Wooyoung was still going. "Cumming twice for me, hmm?" He snickered. San could practically hear his smirk. "So greedy, I haven't even cum once today. Will Sannie be good and wait for me?"

The demon's dissatisfaction was shut with a single shush and allowed Wooyoung to pound into him with no questions asked. His painful overstimulation was either unnoticed or completely ignored as the dom only moaned in satisfaction. "Fuck Sannie, you keep clenching."

Back and forth, his body rocked with every hit from behind, like a rag doll being tossed by its owner. The thought tempted Wooyoung to go just a little longer, even if he knew the poor demon's prostate had been abused. He was a crying mess and it was beautiful. "So weak for me."

"Wooyoungie, i-it hurts..."

"Just a bit longer Sannie...Oh fuck, fuck San!" Wooyoung filled him to the brim and San whined at the unfamiliar feeling.

Wooyoung made sure he was alright before carefully pulling out. The older fell against the bed with a ginormous sigh, with his boyfriend sliding next to him soon after. San cuddled up to him, wrapping his arms around his torso and pecking his lips. "My poor ass," He whined.

"I'm sorry San, was I too much?"

"Never." Wooyoung giggled at that, gently stroking the demon's hair. "You should top more often. That was fun!"

"If you can go one round without choking me, then we'll see."

San nodded at him, smiling brightly as he snuggled closer. "I love you, Wooyoungie."

"I love you more, Sannie."
