“Grab the horn.”

Shiron hesitated at Yuma’s words.

Yuma’s words sounded like a dubious proposition to Shiron’s ears.

Yuma’s embarrassing parts… Wearing barely enough clothing to cover her breasts and genitals, and coming into his room and sharing a bestial kiss moments ago—all of it felt unreal to Shiron. So when Yuma told him to grab the horn, he couldn’t help but wonder what on earth was going on.

Yuma had taken on the role of a guardian since childhood. In a sense, wasn’t she like a mother figure to him?

Even though he received nurturing out of necessity, Yuma had momentarily made him feel like he had a mother. The fact that they, like beasts, were engaging in kisses, made Shiron feel a whirlwind of emotions.

It wasn’t revulsion at the thought of incest, but rather the difficulty of accepting Yuma’s state rationally that was the issue.

Demons held their horns dear, and demons with damaged horns lived their lives in shame. Knowing such a setting existed, Shiron didn’t know how to react to Yuma’s command to touch the horn.

“Are you… really okay?”

As Shiron’s discomfort grew, he hesitated, only touching Yuma’s white cheek and red lips with his hesitant fingers. Enjoying the tender touch filled with hesitation, Yuma slowly nodded his head.

“If I allowed just anyone, it would be a meaningless act. That’s why I want only you, my lord, to grab my horn and enjoy the pleasure immediately.”

“…Okay.”

Seeing Shiron hesitating, Yuma, impatient, instead took his hand and led him.

“Well then, hurry.”

Reluctantly, Shiron wrapped his hand around the twisted horn.

It was a gentle touch. When their hands touched her horn, Yuma flinched.

“W-well, excuse me.”

Realizing Shiron’s discomfort, Yuma immediately put on an awkward expression, her lips trembling.

Scribble.

Before putting his penis in her mouth, Yuma signaled submission by kissing Shiron’s earlobe aloud. Shiron swallowed the moan that tried to burst out, his waist jerking.

It was electrifying.

Just touching lips at the end, an electric current flowed from his waist to his head.

Yuma thought Shiron’s agitation transmitted through the hand holding the horn was cute.

What kind of face would her lord be making now?

Curious, Yuma lifted her lips from her lord’s penis to check Shiron’s face. Sticky precum touched her red lips and dripped down, forming transparent threads.

Looking up, Shiron had wide eyes, gripping his hand tightly around her horn.

“You seem to be feeling good… We haven’t even started yet.”

Seeing Shiron reacting properly, Yuma gained confidence. Any signs of hesitation disappeared.

Instead, what filled Yuma’s head were the sensations of her ticklish lower abdomen and Shiron’s throbbing penis.

The soaked tip became so moist that it couldn’t be reversed.

“Hmm… It tastes different from what I imagined.”

Yuma savored the taste of precum as she licked her lips.

She thought there would be no taste, but it was salty.

“…But that’s not important.”

Satisfying her sudden curiosity, Yuma again pressed her lips to the tip of Shiron’s penis.

Suck.

Slowly, languidly…

Suck.

Her lips completely enveloped the penis. Unlike the chilly air outside, Yuma’s mouth was warm and cozy.

Immediately, her hot tongue adhered to the back of the penis, and Yuma’s long tongue coiled around it like a snake.

Yuma took Shiron’s penis into her mouth, licking every nook and cranny without missing a spot.

Even the dirty places like behind the glans.

The penis, which filled her warm mouth, was thoroughly soaked with saliva.

Shiron, feeling ecstasy for the first time in his life, squeezed his hand tightly.

It felt good.

So good he felt like going crazy.

A stimulation several times stronger than the pleasure he felt when he kissed Yuma’s lips surged through his head.

Though he felt like losing his mind, Shiron made an effort to properly look at Yuma’s face.

Yuma maintained a calm demeanor as she savored the penis, in stark contrast to Shiron’s rough breathing.

“Chwip, chwuk, huroop, chwureureurip.”

With her eyes gently closed, Yuma moved her head as if sucking the most delicious candy in the world.

“Chwip, huroorup. Ho-ok.”

It wasn’t just a simple back-and-forth movement of her head; she used her tongue meticulously, occasionally touching her throat to stimulate the glans.

Moving her head and tongue simultaneously was a challenging feat, especially while suppressing the urge to gag as the penis reached her throat.

These skilled movements were definitely not those of a beginner.

“Hu-eok… You’re, you’re so good at this?”

“Chwup, thank you… Huroop. I’ve been… practicing… It feels rewarding.”

Yuma had wisely practiced with a well-lubricated root vegetable from the sexual supply shelf. Pleased with the compliments, Yuma passionately caressed the penis even more.

“Chwip, hu-um, chwureurip, jjik, jjyu-uwup.”

Yuma’s skilled oral technique made Shiron feel as if he were in paradise with just the penis.

The sensation of climax grew as quickly as the intensity of pleasure.

“Hu-u…”

Shiron took a deep breath, exerting force on his sore lower abdomen. He tried to delay ejaculation by controlling his breath.

The penis, filling Yuma’s mouth, twitched. Yuma found the instinctive signal amusing and honest, so she chuckled.

‘How amusing. He could just release as he pleases.’

Thanks to Shiron’s occasional honest reactions, Yuma felt pleasure and happiness while sucking his penis.

It felt like her brain was melting. Her sucking mouth was hot.

Her nasal cavity was filled with a tingling, electrifying scent.

Each time, the smell of Shiron’s body filled her head, making it difficult to think rationally.

Feeling uneasy despite being in a position of service, Yuma’s hand holding Shiron’s thigh kept moving toward his penis. She thought it was embarrassing to indulge the whimsical antics of the lustful vagina and managed to suppress the urge.

“Chwip… Ok.”

Yuma snapped out of her thoughts as she pushed the penis deep into her throat.

However, despite her determination, her body, unfamiliar with the experience, was overwhelmed by a slight urge to vomit.

Although she had learned how to move her tongue and manipulate her mouth and head from the short readings, the sensation in her throat was more intense than during practice.

Despite the urge to vomit, she managed to avoid actually doing so.

In preparation for this moment, Yuma hadn’t eaten lunch. Furthermore, enduring minor physiological discomfort was nothing to her, so there were no issues at all.

At that moment, the penis in her mouth started twitching and jerking more frequently, as if it wanted to expel thick, dark semen right away.

‘It seems like it’s about to happen.’

While manipulating the penis with her tongue and throat, Yuma withdrew her tongue and widened her throat.

The penis went deep into the open throat.

Feeling the forced sensation, Yuma wrapped her arms around Shiron’s waist and shook her head.

Chalpak, chalpak.

As her head moved vigorously, her chest, which had remained still due to its large size, began to sway with gravity.

Her two large breasts, which had been motionless in their place, now collided with each other as her body became more agitated.

Shiron swallowed his saliva as he watched the spectacle unfolding under his head.

His gaze fell on the large, red tip of the erect penis. Yuma’s nipples were so stiff from excitement that they were swollen and red.

‘It must be difficult to suck in this position.’

Despite the overwhelming pleasure, Shiron suppressed the desire to suckle on the breasts. Instead, he increased the strength of his grip in response to the gradually accelerating rhythm.

Unlike his right hand, which held the horn, his left hand had nowhere specific to go, but Shiron knew exactly what it should be doing.

Shiron, with a face full of desire, instead gently shook his waist, enveloping his hips with her smooth hair.

“Huroop. Chwurup. Huroorup.”

Yuma synchronized her movements with Shiron’s waist, and the penis was thrust vigorously into her wide-open throat without bending, causing a rough sensation.

Ggeltteok, ggeltteok, ggeltteok.

It was a texture that could only be described as chewy, not just in the mouth.

When the glans were wrapped and eventually swallowed to the root, it felt like what enveloped the penis was not a mouth but something else entirely.

“Keuheuk…”

Kkuuuk- Eventually, as the sensation of climax became unbearable, the hand gripping the horn pressed hard against Yuma as Shiron climaxed, paying no attention to her needs.

Shiron grabbed Yuma’s head and forcefully pushed the penis deep into her throat.

Kkulluk- Kkullung-

The thick, sticky semen, eager to come out, poured down her wide-open throat.

Despite Shiron’s rough touch, Yuma closed her eyes quietly and accepted the ejaculate.

Ggulgeok ggulgeok.

Her closed eyes squinted. She breathed in roughly through her nose, swallowing the semen down her throat. Each time, as if urging her to swallow more, Shiron stimulated her by tightening and loosening his grip on her throat.

“Chwureureurip. Chwurip.”

As if determined to swallow even the semen inside the urethra after ejaculation, Yuma slowly lifted her head while maintaining the vacuum in her mouth around the penis.

Jjo-o-ok poong-

Gradually, the saliva-coated lips and the ejaculated semen on the penis formed a thin string. Since most of it had been poured into her throat, the thick semen didn’t fill her mouth.

“Huroop. Huroorup♡”

With a lingering sense of regret, Yuma slurped the ejaculate clinging to the tip of the penis with a crude sound. She sucked on Shiron’s penis as if she wouldn’t let a single drop of his ejaculate escape.

She licked up every drop of saliva, semen, and pre-cum mixed together on the horn, making it feel robust and vigorous.

“Eung, chwup, jjook, jjok♡”

The highly sensitive penis after ejaculation was subjected to intense stimulation. The sensation was beyond words. It was a level of pleasure far beyond what one could imagine while idly playing with oneself.

“Eu, eugeuk!”

Shiron tried not to groan loudly, but Yuma, instead of complying, ignored Shiron’s command with a smiling face.

“Heoeeokeuk… Stop… heu-eok…”

“Uum, I won’t stop, chup, there’s nothing… huroop♡”

Even after ejaculating, Yuma didn’t let go of the penis. Whenever Shiron’s hand tried to pull her head away from the penis, Yuma, unfazed, embraced Shiron’s waist, pressed her head against his groin, and swallowed the penis.

The sensitized penis was once again buried in stimulation. Needing a break, but Yuma didn’t give Shiron a chance to catch his breath. Shiron’s gaze shifted upwards, and he felt like he might lose his mind soon.

Poong-

Finally, after completely cleaning the ejaculate from the penis, Yuma took Shiron’s penis out of her mouth.

Jjo-ok. Jjok.

But Yuma, still feeling regretful, covered Shiron’s penis with kisses, her face pressed against it affectionately.

“……I said, stop it.”

Breathing heavily, Shiron looked at Yuma, who kissed him passionately, with eyes filled with resentment.

Unperturbed, Yuma continued to kiss Shiron’s penis as if flaunting her affection.

Jjo-ok jjok…

“As expected of the master. You won’t let a single drop go to waste.”

After what felt like a long time of sucking, yet the thick, long penis didn’t shrink at all. Instead, it swelled even larger than before.

“I’d be disappointed to end it like this… Thank goodness.”

Finally, the time had come. Yuma stood up, swallowing her saliva, and as the fountain of ejaculate rose from her vagina to the floor, she staged a spectacle.

Whether it was ejaculate or honey, the viscosity was such that it couldn’t be distinguished.

Sreureuk- Cheolpeok-

The knot of her panties came undone, and the soaked panties stuck to the floor with a crude sound. Yuma, who had untied even the sweaty nipple covers, stood next to Shiron and placed her hand on his crotch.

Jjilggeo-

“Haa… Haa… Young Master. Do you see it?”

Yuma grabbed the thick penis with her hand and began to spread her vagina apart.

Even though it was exposed underwear, she was worried he would see some hair, but sure enough, there was no coarse hair covering her vagina. Thanks to that, only the smooth vagina, wrapped in two folds of flesh, was clearly visible.

“This is a vagina.”

“….”

“A vagina. Hoo… From now on, I will accept Master’s manhood here.”

Yuma spread her vagina with two fingers and showed the opening to Shiron. Thick syrup dripped from the opening, and a scent that drove males crazy emanated from it.

It was so provocative that it could not be described; it was as if urging to insert the penis immediately.

“Originally, this place should be lubricated enough with hands to be prepared… But Master’s scent is so attractive and enchanting, that’s why everything is ready already.”

Yuma spoke freely, without considering what she was saying or caring if it sounded vulgar.

Because her Master, who couldn’t take his eyes off her vagina, looked so adorable that she wanted to skip explanations and engage in intercourse right away.

Yuma moved her hand to Shiron’s cheek with a slurping sound.

She caressed his cheek that held the penis with the hand that had touched the vagina.

This could also be considered as sex, but Yuma wanted to have sex by pushing the penis into the vagina.

“Excuse me.”

Yuma placed her hand on Shiron’s chest and straddled him.

While doing so, Yuma gently pressed her lips against Shiron’s, as if wanting more.

Even though it was sticky with ejaculate and saliva, Shiron couldn’t resist Yuma’s will.

He felt completely overwhelmed by her presence, no matter what happened.

A magnificent sight unfolded.

As Yuma leaned forward, the tip of her firm breast swayed round and round above Shiron’s chest.

The sensation was so unusual that Yuma trembled even while kissing.

Meanwhile, Yuma didn’t forget to insert the penis into the vagina.

Her slender, white hands began to fondle the penis.

To give Master a heavenly experience, Yuma fervently stroked the firm phallus against her vagina with only her senses.

But it backfired.

The excited vagina, swollen with blood, did not tolerate the stimulation, and immediately sent a thrilling pleasure command to the spinal cord.

With her legs weak, from the position where the tip of the glans and vagina barely touched, the penis was pushed in all at once.

Wriggling, and then, with a swift movement-

“Heu-eueuk♡”

Yuma closed her eyes tightly and swallowed the shock of the penis penetrating her vagina.

At the same time, a slight dizziness engulfed Yuma, and as the penis penetrated the heated vagina, a lightning-like pleasure whipped her head.

“Ah… Aah♡!”

Not the mature woman’s voice that had been coming out all along, but a delicate girl’s voice.

Yuma, who was overwhelmed by the rushing pleasure, responded belatedly to the pouring pleasure.

Strangely, there was no pain. Even though the penis was inserted into that precious place to the end.

In the books she had read, it was said that there would be a painful sensation at the beginning of penetration, but perhaps because it was a different body from humans, her vagina felt not pain but pleasure.

The pleasure turned the mature woman who had lived for hundreds of years into a fresh village maiden.

Jjilggeo-

“Master, please forgive me for riding on top.”

Jjikgeok-

Although she was asking for permission with her mouth, Yuma’s waist moved on its own accord already.

“T-then I’ll move.”

She was already moving. Yuma seemed not to know what she was doing right now.

That’s how full her mind was with ecstatic pleasure.

Her determination to educate her Master about sex had long flown away, along with the tremendous pleasure and immediate gratification.

While conflicting between the instinct to please her Master and the immediate pleasure, Yuma’s soft buttocks continued to sway.

On top of his firm penis, Yuma made a stroke with her large buttocks.

Jjilggeo-♡ Jjilggeo-♡ Cheolpeok-♡ Cheolpeok-♡

Without stopping, Yuma kept pounding. It felt as if she was caressing the hot phallus with her fingers, kneading, teasing, and stirring, as if it would melt away, but at the same time, it felt like licking the hot phallus with multiple tongues inside the vagina.

“Breasts…”

Shiron couldn’t regain his senses, feeling like the vagina was a separate living being, yet he couldn’t take his eyes off the massive fruit swaying in front of him.

Shiron tightened his trembling grip.

His hand, which had been caressing her chubby thighs, moved up to her hips, and he grabbed her swaying breasts. When his fingers touched the stiff nipples, it sent a thrilling and blissful sensation through Yuma.

“M-Master?”

Yuma widened her eyes at Shiron’s actions but didn’t stop her movements.

Confusion couldn’t overcome pleasure. The vagina, seeking pleasure continuously, kept moving her buttocks relentlessly.

“Breasts. I want to suck your breasts.”

“Yes… Oh♡”

An explicit and confident request. Yuma leaned forward, her upper body bowed, with her breasts held, and pressing her vagina against his crotch.

As Shiron enjoyed the pleasure rising from his penis, he fondled Yuma’s breasts and then… he sucked on them like a bear

“Aah♡, Master…♡”

Yuma felt a burning sensation on her face, as if it would explode from Shiron’s primitive actions, experiencing ecstasy.

“D-Did you want my breasts that much…”

Jjuwup-

Shiron didn’t answer but was fully immersed in tasting Yuma’s breasts.

Eut♡! Heueut♡!

Yuma’s response to her breasts being sucked was amusing.

Every time he swirled and flicked her nipples with his tongue, and every time the penis wrapped in the vaginal walls twitched, Yuma’s breasts felt like a controller connected to her vagina.

Now that she had taken control, it was natural for Shiron to take the lead.

Eut… Eut♡! Eut… Heug♡! Ah♡, Haaah♡!

Yuma closed her eyes tightly, enduring the pleasure from her vagina and breasts.

Eut… Eut♡! Eut… Heug! Ah♡, Haaah♡!

But the pleasure, so different from her usual self, couldn’t be resisted.

She could only endure for a moment. Yuma moaned, her head thrown back, spitting out beautiful screams.

Unable to resist the pleasure, Yuma’s buttocks, which had been grinding, stopped.

However, she felt that the incoming pleasure didn’t diminish.

Instead, the tightly gripped vagina seemed unwilling to let go of the penis, just enjoying the sensation.

Meanwhile, Shiron thought the stimulation was lacking.

As Yuma’s large buttocks, which had been eagerly seeking ejaculation, stopped, the pleasure transmitted to his penis decreased.

“M-Master?”

Then, Shiron raised his upper body and changed positions.

From her taking the lead to yielding dominance, Yuma followed Shiron’s movements, realizing her mistake. She not only relaxed her body but also felt the force from below pushing upwards, causing her to fall back onto the bed.

Pulsuk-

“M-Master.”

The dim light gently illuminated the beautiful figure.

There was no spreading of large breasts due to gravity.

Perhaps embarrassed by this sight, Yuma blushed and used both hands to gather her breasts to make them look pretty.

It was a provocative scene. The instinct of a male cried out to indulge in the delicious-looking body in front of him.

As Shiron pressed his body against the spread legs, admiring the messed-up vagina with foam, he soon…

“You only choose the best things to do.”

“Compliment… Ah♡. Thank you… Ah♡Eut… ♡! Eut… Heug! Haaah♡!”

Cheolpeok!

Yuma bounced her waist in response to the pressure.

Cheolpeok! Cheolpeok! Cheolpeok!

She started shaking her waist without hesitation.

With intense friction and the already heated body temperature, Yuma’s insides melted sticky.

The walls of the vagina, the folds beyond them, released sticky ejaculate as they wrapped around the penis.

With each thrust into the vagina, the rough, unshaved hair stimulated the pelvis, and the wide-open, firm thighs made a sound, providing just the right amount of resistance.

“M-Master.”

“Uh, Uh-eo-eo-eok. Why,”

“Kiss, please.”

While his penis was thrusting into her vagina, Yuma demanded a kiss from Shiron in a tender voice. Shiron didn’t refuse and, without stopping his waist movements, leaned forward.

Yuma grabbed Shiron’s black hair and pulled him closer to her head.

Although her intention was to suckle her breasts, her instinct was to mix her tongue with Shiron’s and decorate the climax.

“Yuma really loves kissing, doesn’t she?”

“Chururup. Churup. Yes. I love kissing Master so much. Hwoong♡!”

Yuma teased with her tongue and lips without even finishing her sentence.

At that moment, Shiron’s prostate tightened. Unable to contain the built-up ejaculation any longer, he pressed his waist firmly against Yuma’s open legs while devouring her lips.

“Chururip, M-master. Please stay just like that inside!”

Yuma instinctively realized what that action meant and wrapped her legs around Shiron’s waist.

A keen eagerness to receive every drop of semen into her vagina.

Yuma squeezed Shiron’s waist with her tightly closed vagina and legs, not allowing him to move an inch.

The tingling glans touched the tight cervix, and the cervix, as if determined not to let go of the glans, sucked and licked it.

There was no need for words.

Shiron and Yuma trembled together, pressing each other tightly.

And then,

Burrurruk! Buk! Burrururur!

With a tingling sensation, the penis, frothing in the vagina, ejaculated sticky semen.

Shiron felt refreshed and accomplished. Yuma, feeling the warm liquid pouring into her abdomen, surrendered to immense pleasure, letting her ejaculate flow out.

“Jjok♡jjok. Churup♡.”

Even as ejaculation continued, the kissing didn’t stop. The two lovers opened each other’s mouths, entwining their tongues, shivering with pleasure as they pressed their waists together.

Even after ejaculation, Yuma didn’t release her legs.

Continuing to kiss passionately until the heat subsided, Yuma squeezed out love and semen as if she would devour everything about her Master.
