diluc wants to baby trap his ex-bf zhongli to get him back, and summons incubus kaeya to seal the deal ❤ thread starts below!⬇️

Diluc stared down at the book incantations, gnawing on his bottom lip. The Latin words felt odd on his tongue and no matter how many times he tried to sound it out, it never came out right. He was beginning to lose hope of every getting Zhongli back.

"He's mine...I'll get him back." Diluc murmured to himself to hype himself up. They were destined to be, and nobody could tell him otherwise. It didn't matter if the man had moved on to some other trash slut. They were merely a body.

But Diluc was capable of so much more for him. He knew how to make him happy, how to care for him foot and hand, and how to be everything he needed. Zhongli didn't need anyone else, but him. The man didn't know that, but that was Diluc’s fault for not doing everything he could.

He would make the other man see that soon enough. Diluc had gotten a look at Zhongli and the new boy toy he had gotten with. Diluc had scoffed the first time he saw the twink, and after some digging he got a name. Aether.

The name alone made him sneer. Sure, he had a cute little twink body which he knew Zhongli liked and a head full of golden hair, but it was merely a phase. Even Zhongli didn't know what was good for him, but Diluc would make him see he alone was the best for him.

He would do something that nobody else could for Zhongli, something the man had always craved for and it was the one faulty Diluc carried that he could not accomplish what the man wanted most. But, all in due time.

Diluc sighed as he sat in the middle of the pentagram star he made, "Maybe I'm not the saying the words right." He muttered to himself. Summoning an incubus was harder than he thought. He had good reason to believe he bought the right books for the summoning spell.

They cost him a pretty penny, and were technically illegal for him to own but a small price to pay to get the man he wants. Diluc ran his fingers through his hair again in frustration, and stood up in the middle of the star. Maybe he needed to do some dramatic movements...

...like in the movies! Diluc already offered all the relevant items to attract an incubus; a prickly rose full of thrones, a bowl full of bitter dark chocolates, and the skull of a crow. He didn't know why the books called for such things, but he acquired them just fine.

So, it had to be way he was performing the incantations that were wrong. Diluc tried again, murmuring the odd words with more enthusiasm and spreading open his arms in a welcoming gesture. His eyes fluttered closed, and he truly believed with all his heart this would work somehow

When he finished the chants, Diluc waited for a moment with his eyes closed but the feeling of disappointment was back already. "Fuck, what else could I be doing wrong?" He huffed, and opened his eyes to glance down at the book with a frown.

"Hm, maybe you should take your clothes off and dance in a circle to entice me." A sudden cool voice came behind him, and Diluc whirled around with a sharp gasp. A handsome man floated near his window, long legs crossed as if siting in some invisible chair.

He was beautiful, made to entice and charm anyone who laid eyes on his glittering figure. Literally glittering it seemed because the gown he donned looked to be made of pure darkness and stars. It looked to be like a silk dressing gown...

...but he wore it like it was the single most priceless piece of fabric in his possession. Diluc could see the powerful chest through the lapels of the gown, and how one tug would have him completely naked. Sun tanned skin on display that Diluc wondered...

...how it would feel like to kiss. And he could tell the man was totally nude underneath; the gown was incredibly sheer, and his eyes nearly bulged out of his head when he saw the massive cock he hide beneath the sheer fabric.

The look of utter primal hunger in the sharp smile of the man made Diluc shiver. The book suggested sometimes the summoner never made it out alive when trifling with a incubus, but...at least he would die with a good fuck.

Diluc shifted nervously when the single all black eye considered him carefully, though he curiously noted it wasn't a dull flat black. There seemed to be a whole galaxy in his gaze with how the orb sparkled with the light. His other closed eye had a jagged scar over it.

"So," The man uttered. Perfectly calm and cool. "Are you going to dance for me, little human?" He inquired with a tilt of his head.

Diluc gulped nervously. He remembered the books saying to never disobey an incubus, if that is in fact who he summoned. "I...can. If you want..."

The demon hummed, and glided down from mid air to land in front of Diluc soundlessly. The scent of dark lust immediately hit him, and it took every ounce of Diluc to not just drop to the ground with his ass up. He didn't even know lust had a smell, but...

...but the demon in front of him was intoxicating. Like rich musk that clouded his mind and set his core on fire, slick already pooling at his apex and the demon knew this. Said demon chuckled low, "Oh no, I've watched you chant and dance enough to know you really want this."

The demon towered above him so much that Diluc had to lean back up to look at him. He was inching closer and Diluc's fight or flight instincts were beginning to act up, conflicting with his surging arousal.

Diluc licked his lips, "You...watched me?"

The incubus only smiled, that glittering orb curving into an attractive half cresent, but ignored his question. "Now, tell me, what is it you want with an incubus?"

Diluc breathed through the suffocating and powerful aura that seduced him every second. "I..."

He hesitated. Did he really want to go through with this?

The incubus brought his attention back with a single snap of his fingers, his expression turning sharp and more deadly. "Speak, or I shall leave now."

Diluc panicked. "I want you to get me pregnant!"

The incubus' black orb seemed to brighten even further, crowding closer to Diluc with a pleasant rumble that had the petite man shivering. The demon seemed to be scenting him. The drag of a nose along his cheek had Diluc gasping, tracing a line down soft curve of his jaw.

Diluc tilted his head back when the demon slowly nosed his way down his neck, stopping just where his pulse fluttered wildly. "Exquisite." He breathed, and Diluc couldn't hold back the soft whimper of need that escapes him. God, he was practically drunk off him already.

"So, you want to carry my powerful seed? A tiny, fragile little thing like you..." The demon murmured, almost fondly as his large hands settled around his waist and Diluc swore he could probably engulf it whole. "I would laugh at such a thing, but..."

He faced Diluc again, their lips nearly brushing together. The redhead stretched up to meet him out of instinct, but the incubus barely pulled out of his reach which made him whimper again. "You are by far the most impeccable human I've come across."

Diluc's cheeks flushed deeply at the words, the incubus slowly backing Diluc towards his bed. He was completely entranced as he watched the man's wicked snake tongue flick against his plump lower lip. "You will do well in carrying my children, no matter your ulterior motives."

Diluc felt his entire body nearly burst into flames at the thought of being taken so throughly by this powerful demon, to be appraised and sought after to carry equally powerful children. Diluc was already forgetting his original reason to become impregnated.

His reverie was broken when he landed on his bed, and looked up to the demon who was seconds away from ravishing him. He dropped the robe from his broad shoulders, and stood in all his glory in front of Diluc. The redhead squeezed his thighs together...

...as he took in his beautiful figure. All sleek with curved elegant muscles and smooth skin, the sharp V of his hips drew the human's attention to the fat and girth cock that hung heavy between his legs. Visibly erect already, and ready to fill Diluc to brim with his cum.

He even noticed the slight raised bumps along his cock, and Diluc groaned to think of how the cock would stimulate his tight cunt so well he could end up cumming multiple times until he passed out.

"I-I can take it...you and your s-seed." He stuttered the unfamiliar word...

...unused to this kind of talk, but made him so fucking wet between his legs.

The incubus chuckled, and parted his legs to rip of his jeans with one sharp tug. Diluc squeaked as his ass hung off the edge of the bed, but the demon caught him by the legs easily.

"Your tenacity is admirable, but you'll have to prove your words, little one. Sex with a demon is...rough to say the least. Much more with a demon like me...absolutely animalistic." He salaciously grinned at him, spreading his legs wider apart so he could stand between them.

Diluc's hand was covering his slick cunt, the red from his cheeks slowly traveling down his neck from how hirny and embarrassed he was from all this. But the demon was having none of it. He slapped Diluc's hand away, and rumbled in approval...

...at the sight of the cherry red slit that peeked between his glossy folds. Rough fingers spread him open, coating the long fingers in his wetness and teasing the sensitive area until Diluc was panting and moaning.

"A pretty and delicate flower for me to defile."

Diluc nearly sobbed when a single finger slide inside of him with no resistance, quickly engulfing it with his wet heat that begged for more. Begged for the smirking demon above to pump him full of his cum because he deserved it, and he knew he could handle it.

"Yes, I want you deep inside of me. You're the only one who can get me pregnant." Diluc pleaded as the incubus pumped his finger slowly, adding two more fingers suddenly that made him keen in delight. The incubus other had settled over his lower tummy, and Diluc felt an odd..

...tugging sensation. He glanced down at to see a glow of icy blue lines ink his skin to form into a beautiful, intricate design that reminded him almost of a heart. He felt his core open up even more and absolutely weeping with arousal. "Now you bear my mark."

"Your m-mark?" He asked, and groaned when the incubus withdrew his fingers to slick up his enormous cock between his drenched folds.

"To let others know your womb, body, and soul are mine now."

Diluc gasped each time the tip teased his hole, squirming hard.

"B-But you don't know my name, I don't even know what to call you--" Diluc cried violently when the other sheathed himself into his tight pussy in one brutal thrust that left him trembling with watery eyes.

"I know you, Diluc. Just as you know me,"

The redhead could feel him up to his belly button, and he was sure he had a bulge to prove just how fucking big this demon was but his pussy loved to be stretched. The other set a hard and fast pace that had Diluc bouncing on his pastel sheets, knowing he's going to ruin them.

"You and I are one in the same. Creatures who want to dominant over another." The incubus continued as he fucked Diluc wide open, forcing his knees apart so the redhead wouldn't close them when he hit that spot deep inside of him.

His own wetness provided the demon all the he needed to throughly pound the hell out of Diluc. The heavy smack of skin echoing in his tiny bedroom between his own high pitched moans, loving how the demon was tearing him open and marking the deepest place inside of him.

Diluc's hands reached out to grip the other's biceps, glancing up at him with doe crimson eyes and tear stained cheeks. "S-So good, so fucking deep, get me pregnant please!"

The incubus' face pinched in pleasure, and concentrated on angling into his womb.

The tip beginning to force its way in, a different kind of pain that had Diluc creaming heavily around the girthy shaft but walls drawing him in even deeper.

"You fit perfectly around my cock, Diluc. You're made to take it, just like you're made to be swollen with my cum."

Diluc hicupped in-between anguished crises of pleasure as the throbbing cock penetrated him deeply, nodding his head desperately. The thought of Zhongli long gone and replaced now by the demon pummeling his insides with a single goal.

"Then say it."

The incubus insisted, he leaned down to brush his lips against Diluc's. "Say you're mine, and seal the deal with my name."

It was the incubus' own trap, but Diluc did not care of he fell for it. A name was given to him, and Diluc on the high of his incoming orgasm...

...uttered it frantically like the mantras he used to summon the demon in the first place. "Kaeya, I'm yours! Please, cum with me. I want it so badly." Diluc begged, and arched off the bed as the demon blessed him with his heavy load inside his womb.

The tattoo glowed bright as a result, Kaeya grinding harder into him as his walls milked the other dry. He wasn't nearly full yet, but he was satisfied nonetheless. The demon nosed along his neck again, and then finally gave him a proper deep kiss.

Days later, Diluc finally emerged from his bedroom. Riddled with love bites, bruises and scratches, and a nest for hair but he was thoroughly fucked out courteous of Kaeya. There was no doubt he was pregnant after their journey or debauchery.

"Did you actually give me your true name?" Diluc questioned when Kaeya slipped on his gown, almost ready to depart for some "business".

"I am known by many names. Morningstar, Beezlebub...Lucifer. But Kaeya is my preferred name."

Diluc choked on his glass of water, "L-Lucifer?" He stuttered, staring wide-eyed at the demon.

Kaeya only grinned at him and bent down to kiss his forehead, "I will be back. Do not fret, little one. You will be a wonderful for me..."

And just like that, he was gone. Leaving Diluc dumbfounded at the fact he had made a deal with a devil. The devil.
