Chapter 115: Essence Absorption
Chapter 115: Essence Absorption
Succubi—or "Lust Demons," as they are known in the demonic tongue—are a race specialized in sex. This specialization goes beyond merely seducing and enchanting the opposite sex or providing pleasure; it includes a biological trait where they derive nourishment through the consumption of semen produced by males.
For a Lust Demon, consuming semen was both a life-sustaining necessity and a form of entertainment. Much like humans seeking out famous restaurants for a better meal, these demons acted as both patrons and chefs, seeking out men who produced high-quality semen and using every technique at their disposal to squeeze it out of them.
Among those techniques were the ones Jaejin had already experienced: forced erections, aphrodisiacs, charms, increasing ejaculation volume, and Lust Crest imprinting—actions primarily intended to enhance the enjoyment of the act itself. However, there were several other techniques that Jaejin, despite his position as a Demon Lord candidate and the future Demon Lord, had not yet encountered.
One such technique was Energy Drain, also known as nutrient absorption. This skill allowed the demon to absorb the target's power through the semen they ejaculated. It was a demonic art that could steal everything from mere vitality and stamina—which would recover in a day—to permanent attribute points.
The sensation of having one's power drained was often several times more pleasurable than a normal ejaculation, leading many to become prisoners of that ecstasy. However, since the Demon Race Pact was established to guarantee minimum rights for humans, Energy Drain performed on human males had become rare, except in certain specialized brothels. Consequently, Hilda, who knew nothing of the treaty's contents or even the proper way to use demonic energy, had performed a Drain purely through instinct.
Following her instincts, she absorbed Jaejin’s semen and, as a Lust Demon, instinctively realized how to make the meal even more delicious. In particular, the absorption of memories through this process was a trait that manifested only in a select few Lust Demons.
"To think... you'd turn... someone into... a Lust Demon... just like that...♡"
Hilda spoke in broken gasps every time she slammed her hips down, relentlessly toyed with Jaejin’s cock. Even after he had finished ejaculating, Jaejin was given no rest; his sensitive member continued to be caressed, forcing him to groan as he gripped the bedsheets.
"Ha... ugh... hngh...♡"
"A Demon Lord with a face like this? You can't even win against a woman's pussy♡ Cum for me♡ Cum for me♡"
Slap, slap, slap, slap. As the sound of her butt cheeks striking his thighs echoed through the room, Jaejin’s cock responded by drawing up more semen.
Splurt. Splurt. Accompanied by pathetic moans, the semen was shot directly toward Hilda’s womb.
The sensation of his strength being drained provided a thrilling, brain-melting spark that pushed Jaejin to his limit. He tried to arch his back and heave his body, but he was pinned down by Hilda’s hands pressing firmly on his abdomen, leaving him unable to move.
"Don't struggle♡ Acting with order is the lifeblood of a knight♡"
With every ejaculation, his memories were read and his strength was stolen. By the time he realized this, he had already ejaculated several times and was so thoroughly charmed that he couldn't put up any meaningful resistance.
"But you should be grateful. Thanks to becoming a Lust Demon like this, my head has finally cleared♡"
Having learned about the circumstances and the nature of Lust Demons from Jaejin, Hilda took the time to organize her thoughts while squeezing a few more rounds out of him in the cowgirl position.
It was true that she had been momentarily flustered when she first read the memory of becoming a Lust Demon. Questions had flooded her mind, starting with how she had suddenly transformed and who exactly Jaejin was.
However, in the face of the overwhelming pleasure that made such questions seem trivial, she decided to accept everything.
Her duties and mission as a knight. Her obligations and marriage as the only daughter of the Myers family. For eight years, she had been exhausted, caught between those two lives and embroiled in petty conflicts with her father.
To her, as she was losing the will to continue a bleak family relationship with no apparent escape, the path of a Lust Demon was incredibly alluring.
Hilda felt no resentment about being forced into a life where she could break her record for the most intense pleasure of her life and enjoy it as a matter of course.
In fact, she was exultant. She felt a sense of omnipotence, as if she held this charming younger male in the palm of her hand, squeezing him dry at her whim.
She never imagined he would be the next Demon Lord, but that wasn't bad either. It was simply a matter of slightly shifting the loyalty she once held for her King.
"Hilda... Noona... stop..."
Jaejin looked utterly pitiful as he surrendered with a faint voice and teary eyes. It had been hours. Hilda had been incessantly milking the juices from his balls.
To her, having just awakened to the pleasures of mating, the word 'restraint' was a pie in the sky. Combining her Lust Demon physique with her knightly stamina, she continued to wring his cock in a tight cowgirl position without stopping, even after he ejaculated.
As a result, Jaejin lay beneath Hilda with his thighs drenched in semen, his upper body soiled with her saliva, and his flushed face stained with spit and tears.
She wanted to devour him a little more. Hilda, who had been looking for an opportunity to indulge her further desires, only regained her composure when she was mid-lick.
'Wh... What have I done!?'
Once her heated body felt a semblance of satisfaction, the rationality she had sealed away in the back of her mind resurfaced.
'I-I'm crazy... I did all of this?'
She knew she had simply been faithful to her rising Lust Demon instincts and that it was all by her own will, but looking back with a clear head, her actions felt entirely different.
It was embarrassing. While she liked the sense of fulfillment and the pleasure, the actions that led to them made Hilda’s face turn bright red.
Jaejin, who had been watching Hilda curiously as she suddenly clutched her face and stopped moving, saw a woman in a robe enter the room.
"I wondered where you were since you weren't at the brothel even at this hour, and here you are, seducing another woman."
The hood was pulled back to reveal green hair and a leaf ornament. It was Nia, who had come to find Jaejin as evening approached.

"You made the Madam angry by abandoning your first customer, and now you've gone and made another Lust Demon, Master."
"Is... is Madam Liana angry...?"
"I'm joking. That guy was a troublesome customer anyway, and she was actually happy because you landed an even higher-ranking noble."
Jaejin’s heart had sunk at Nia’s words, but he finally managed to calm down when she said it was a joke. He figured he could consider the first day a success.
"As for Hilda... did you do something, Nia?"
"I just dispersed a little calming powder into the air. I didn't expect it to be this effective, though..."
The two of them let out a small chuckle at the sight of Hilda, whose face was as red as a beet as she wallowed in self-reproach. Even with the calming powder, the gap between her current reaction and her previous behavior was enormous.
It was likely a reaction to having lived a suppressed life. One could guess that, growing up under a powerful local noble father, she had rarely had the chance to vent her desires.
Having finally composed herself, Hilda felt the two of them staring at her and reached out a hand to Nia.
"Hello. I'm Hilda Myers. I'm a knight from this castle. You must be Nia, right?"
"Uh... yes, that's right. But how did you..."
At Nia’s blinking reaction, Jaejin shrugged. Since Jaejin hadn't heard the explanation yet either, it was only right for Hilda to explain it herself.
"Well, to start from the beginning..."
Hilda began to explain everything, one by one. From how she met Jaejin to receiving his ejaculation inside her. And how, while mating with burning desire, she had suddenly become a Lust Demon.
She explained that as she took in his semen, she instinctively realized she had gained an ability, and by acting on it, she was able to read Jaejin’s memories.
When Jaejin confirmed that her story matched the description of Energy Drain he had heard, he reaffirmed that Hilda had indeed become a full-fledged Lust Demon.
"Then... does this mean you can't go back to your original life...?"
"Well... if I went back to the capital, it would be troublesome because I'd run into many Paladins and Priests, but since I'm stationed here temporarily to handle security, I think I can stay like this for a while longer."
Jaejin breathed a sigh of relief, thinking her life wouldn't be ruined instantly. Since a Lust Demon was indistinguishable from a human on the outside, no major problems should arise.
"It might actually be better, Master, since it connects to our purpose for being here."
"Ah, if she's in charge of security, she'll get close to the Lord...!"
The reason Nia had opened a portal and was traveling back and forth was to win over the Lord of Capia Castle amidst the turmoil in Anzence.
"Those details... I see. Since I'll be the temporary Captain of the Guard, I'll have plenty of opportunities. Though I've only seen him once yesterday."
Just when they were worried about how to even meet the Lord, having help from the inside made it much more likely that things would go smoothly.
He thought he was in trouble after picking the wrong first customer, but it turned out he had gained a valuable connection instead. If this was the case, he had something to say to Liana, whom he had inconvenienced.
"Then come to the brothel when you have time. If you help us, things will be much easier."
"I will, Demon Lord♡ But... it looks like someone next to you has a lot to say?"
At Hilda’s words, Jaejin turned his head and saw Nia, who was breathing heavily and pushing her chest forward. She had already removed her leaf bra, exposing her upper body and areolae.
"Master, what do you think you're finishing? I still have my dinner portion left."
The movement of her breasts as she breathed was truly overwhelming. Her head-sized breasts slowly began to cover Jaejin’s face.
"My body is aching so much I can't stand it, Master... You have to ejaculate inside me until I'm full, okay? Splurt, splurt."
Only after being enveloped by her hot, aroused body did Jaejin realize the cause of her heat.
The scene of a fresh Lust Demon and a pseudo-Lust Demon mating intensely was, unbeknownst to them, no different from a room filled with love potions and aphrodisiacs.
Nia, who had been exposed to it until the aphrodisiac scent had soaked into her body, pushed Jaejin onto the bed with the eyes of a ferocious beast. She lifted her legs and pressed her pussy against his erect cock.
"I'll eat well, Master♡"
And then, shuuuuk. She took the entire length of his cock into her plump vaginal flesh. Jaejin groaned at the pressure that felt like it would make him ejaculate instantly. The final blow to his precarious limit was dealt by Hilda.
"I was going to stop for today, but I can't help it when the table is set like this♡"
Hilda obscured Nia’s downward gaze with her own sky-blue eyes. She kissed Jaejin’s defenseless face directly. As she forced his mouth open and violated him with a French kiss—
Splurt, spurt, spurt. Blocked from both above and below and overwhelmed by the pleasure of being devoured, Jaejin couldn't hold back and ejaculated deep inside Nia.
Even then, Nia’s hungry movements continued as she gripped his erect cock with her vaginal muscles and wrung it out. Jaejin had to resign himself to the fact that his promised five rounds wouldn't even come close to being enough.
