1 Snake Eyes

Diluc was tasked to search an underground cave near Mondstadt. He just didn't expect to see a creature lurking in its

Dark, dry and cold, white wispy breaths would come out of his mouth when he blew. Thanks to his pyro ability, he hasn't started freezing to death as he made his way through with fire in his hand.

Evident from the icicles and preservation of stiff corpses on the ground in small numbers, Diluc could tell how many adventurers have failed.

That's why they handed this job to him. A recently discovered underground cave near Mondstadt.

Though so far, he's only been walking and hasn't encountered anything past cryo slimes and whopperflowers back at the entrance. Naturally, he didn't they'd pose much trouble to deal with, so there must be something else in here.

The redhead continued his trek deeper, passing by more and more bodies encapsulated in ice. Maybe an elite tier monster, he speculated. Maybe a boss tier even. The pyro user didn't know but he braced himself for it. Whatever came his way, he'll vanquish with his flames.

Suddenly, he stopped. Apprehensiveness alerted him something lurked beyond, so Diluc threw his fire to light up the way.

He saw something move—slither—about. And once the area brightened up more, he found the creature.

"My my, a visitor! How rare~" A higher intellect if it could speak and understand human tongue, it gazed deeply at Diluc with their slitted red eyes. Dark skin adorned with a pink cryo mark on their shoulder coupled with gold accessories: wrist and arm bangle, and a cuffed earring, from what could be seen; made their pink hair and darker shaded scales become more prominent. Not that it wouldn't attract attention in first place.

A lamia.

Diluc had only read stories about it. Fiction.

To see it firsthand, made him both guarded and curious.

Then, it rose up from resting on their wrapped up tail. And the redhead could see more.

Exotic and ethereal—a hypnotic allure seemed to pull him closer.

"It's really nice of you to come along. It's been rather lonely here." It slithered closer, languidly. Slowly reaching out to him, enraptured in their unique eyes.

Diluc took a step back, hesitantly. As if the very thought of leaving was unheard of and he was the sinner.

Delicate hands touched his chest. Slightly cold. Pulling him down to the ground. Enabling this closeness as he felt something smooth slither around his legs, loosely.

"I've been starving~" Those cold fingers touched his neck, making Diluc shiver. He couldn't stop looking at their eyes, and their lips met.

Soft. Relaxed. Parting too quickly.

Those lips trailed down to plant another sweet kiss to his jaw, to his neck—

Searing pain jolted Diluc out of his stupor as he pushed this vile creature back. Blood splattered to the ground at the hasty removal as he cupped his wound. Two puncture holes. The redhead gritted his teeth. "You—"

All of a sudden, his body felt hot. Tense. And a surging need took over his mind.

Mate.

His pants felt too tight, and he was sweating profusely in this cold. "What did you do to me?!" Diluc was rendered panting for breath, trying to reign his senses.

The lamia, in turn, licked their mouth, tasting delicious blood. "Don't fret, darling. You're so handsome. I didn't want to just kill you. It'd be a waste." He slithered back to where his bedding of cloths lied, obtained from the items of adventurers that came before, and got himself comfortable.

"Just as you might have thought," the pink-haired male moaned as he played with his cloaca, getting it soaked and ready with slick. "I want you to breed me and give me your children~"

Diluc's dick throbbed inappropriately at the words. His eyes couldn't help following those hands, his stare boring into the now leaking hole, waiting for him. Eagerly beckoning him to put his cock inside and fill it up to the brim—their womb—with his seed.

He bit his lip, enough to bleed, to pay attention to the pain. But the urgent need lingered, overpowering—the only thing in his mind.

The lamia hissed with delight in seeing man unbutton their clothes, removing their vest as that's how far their patience went, and unzipping their pants to reveal their throbbing cock.

Slitted red eyes widened with surprise, and only now felt some nervousness. "You've got a really big boy there." A male's cloaca is deeper than a female's so the creature wasn't worried about not fitting but … it was going to stretch him for sure. Still, despite some unease, he presented himself with collective calm.

"Go ahead. Sow your seeds in me~"

Diluc growled, crawling over to position himself, pointing the leaking head into the twitching hole, and promptly grabbed the lamia's hips to pull and shove himself all the way in one thrust.

The tail under and behind the redhead squirmed and stiffened, as he watched the lamia's head toss back with a scream and their torso arch.

Diluc groaned, feeling the warm walls clench and contract down on him, massaging and tempting. This snake.

He didn't bother waiting and started a brutal and fast pace. Relishing in the howling moans and screams that echoed in the cave. Their tail became restless, and the creature's hands struggled for purchase, holding onto the beddings of their nest tightly as his hot and thick rod slammed and kissed the entrance of their womb over and over again.

The lamia has never been reached so deeply before. Tears sported in the snake's eyes, saliva at the corner of their opened mouth singing pleas of mercy to slow down.

As if Diluc would obey them now. "Since you wanted this, take it."

The lamia could only sob as pleasure hits him with full force, constricting around the pulsing length now plunging searing liquid heat inside his womb.

"I'm not done yet."

The snake whimpered pitifully, helpless at the onslaught of torturous pleasure that made him writhe and scream.

Diluc gritted his teeth, pulling all his strength into pistoning his hips and making sure the lamia didn't run away from him, no doubt bruising their sore hips. He groaned as another wave crashed down on him, spurting copious amounts of cum into the full womb. But his dick was still hard. Not enough.

"M-Mershy."

Seeing their debauched face, Diluc became amused and almost found it cute. Almost. He was still irked about the whole situation.

"If you're sorry. Then swear that you won't harm another human again."

"I-I shwear it. I won't-nngh h-harm people aah-again."

"Good." And he continued thrusting inside tightened walls.

"Aaah! Y-You said-ooh! Aah~!"

"Finish what you've started, you damn snake."

Maybe an hour or even longer has passed when the effects of whatever substance injected in him waned. Finally.

Diluc pulled out his soft member and watched his cum overflow out of the abused and twitching hole. He did a number on the lamia, which served the other right anyway.

And speaking of, the latter was close to passing out. The redhead was surprised they didn't already.

"Hey." The pyro user dressed himself up, uncomfortable that he couldn't properly clean himself off until after he got home, and walked over to wake the snake. "Don't fall asleep now."

"Shleepy. Tired."

Diluc clicked his tongue, and made a decision. Hooking his arms under their body, he carried the creature in a princess style, letting their head rest on his shoulders as their long and flowing pink hair reached his own knees. "Curl your tail around me or they'll drag." The snake wasn't heavy to him, but they're long as hell. Troublesome.

The lamia was mumbling something under their breath that the pyro user couldn't catch, and he felt the shift.

Their long tail shortened slowly, until it was enough to just wrap around Diluc's leg without touching the ground.

Interesting. And better.

"I'm taking you to my house, where I'll be able to keep a close eye on you."

"Mm'kay." The lamia fell asleep by the time he left the cave.

He could've killed the creature for sure. Diluc seldom showed mercy to those that threatened the safety of Mondstadt. Maybe it was the poison still in his body, but whatever it was, he couldn't bring himself to do so.

The lamia was by no means harmless, but if it learned to behave … He'll keep it alive.

That's what he decided on
