Chapter 86: Observations
Located in the basement of the ancient castle that served as the residence of the Lust Demons, this place was known as the Central Prison. It was where those convicted of crimes by the Demon judges were sent to serve their sentences.
Prisoners arriving here underwent a two-week period of investigation and adaptation. After a thorough examination of their physical condition and history, they were brought before either Warden Sitri or Guard Captain Karin to make a choice.
They could choose to repeat those grueling two weeks for years on end, or they could enter a bet with a succubus. If they won, their sentence would end in just two weeks, and they would be returned to society.
Those who chose to serve their time sincerely were transferred to the Western Prison in the Military District. Due to the low number of inmates there, the Western Prison offered a high-quality living environment.
However, only one in ten chose the path of sincere service. The rest, overconfident in their own abilities, accepted the bet with the Lust Demons.
Their logic was simple: there was no reason to refuse a deal that could wipe away a sentence of over ten years in just one month, including the investigation period.
The criminals who had chosen sincere service looked upon these confident fools with pity.
Knowing exactly how terrifying the Lust Demon Race truly was, they had tried to advise their fellow inmates during their brief time together. But despite their kindness, they were met only with contempt and ridicule.
"That’s why you’ll never get anywhere. Imagine being a man and being scared of a woman."
In the macho culture of the Demon Race, refusing a challenge that offered such massive benefits out of fear of a woman was considered worse than being a coward.
But that was a delusion held only by those who had never experienced the true nature of a Lust Demon. The only reason men could "conquer" or bring a succubus to climax in a brothel was because those brothels were part of the service industry.
Lust Demons were a race capable of maintaining absolute dominance in sexual intercourse with any other species. It was absurd to think they would truly surrender just because a male had a slightly large phallus.
The man shook his head. Those who mistook the Lust Demons' clever acting—tailored to a customer's tastes—for reality were always the most ignorant and brave when accepting the proposal.
He didn't know what the demons' ultimate goal was, but he knew these men were all dancing in the palms of their hands. Offering a premature silent prayer for them, the man headed toward the Western Prison, where a comfortable life awaited him.
In contrast, those who accepted the bet remained in the Central Prison. They prepared for a simple wager after undergoing fifteen days of training.
One particular couple had been sentenced to a term equivalent to murder for fraud. They had been caught by the authorities after repeatedly using adultery as a means of blackmail.
They firmly believed they were simply unlucky and that they could start over once they finished their sentence. Accustomed to looking down on others, they were certain they could easily endure a mere fifteen days of training.
The result of that arrogance was now right before Jaejin’s eyes. A man was moaning as he received a handjob while being held by a pink-haired Lust Demon.
The sight of him moaning with his mouth hanging open was a far cry from the confident swindler Jaejin had heard described.
He was ejaculating without a shred of dignity right in front of his wife. Squelch, squelch. Spurt! His wife watched in horror as he sprayed semen as if his cock were broken.
"There we go~ You can spurt a little more, can't you? Spurt, spurt♡ Spurt, spurt♡"
While the husband had been trained by the prison's Lust Demons for the past fifteen days,

his wife had been resting comfortably in a suite prepared within the prison.
After explaining the details of the bet to the couple, the prison's Lust Demons had made an additional proposal. Since a married couple was a community of fate, if the husband alone passed the bet, they would consider both of them to have passed.
The couple had been confident. They had chosen each other based solely on physical appearance and sexual compatibility, disregarding character, family, or social achievement.
Despite being married, they had lived a promiscuous life, seeking out other partners or engaging in group orgies. Even after swapping partners countless times, they had become bodies that could only be truly satisfied by each other. They were bound by a powerful physical bond, if not a mental one.
That was why the wife, who had trusted her husband, was beyond shocked to see him after those fifteen days.
This man, who had conquered so many women—her husband, a "true male"—had been brought to climax by nothing more than a "finger pussy."
"Oppa, how does it feel to ejaculate in front of your wife? Does it feel good? Hehe, the Lust Demon's finger pussy feels better than your wife's real pussy, doesn't it?"
"Hehehe, Mistress Karin...♡"
It couldn't be. Her husband was a womanizer who had won against succubi many times before. Yes, this had to be one of his usual wicked jokes. There was no way he could look so pathetic after only fifteen days.
She tried to believe that, but in truth, the match had been decided before a week had even passed. The pink-haired Lust Demon, Karin, had spent the remaining week meticulously breaking the wife's denial.
"Since you love being ravished in front of your wife, I'll give you a special treat this time. I'm going to take you for real♡"
Karin pushed the man she was holding, forcing him face-down onto the bed. She wrapped her tail around her pelvis once and then stood it upright near her pubic bone.
The tail soon began to swell, transforming from a sharp, pointed tip into a long, curved rod. It was as if she had adjusted it to match the insertion point, mimicking the organ between a man's legs.
"You have to remember this well, okay? I don't care what whore took your virginity as a boy, but the one who took your maidenhood as a man is me, Karin♡"
His body, which had been washed and managed with slimes for a week, was so clean it was hard to believe he was a prisoner. Both inside and out.
Karin placed the tip of her tail against the man's anus and pushed it all the way in, ignoring the wife's grief-stricken cries to stop.
Thud. The sight of the man moaning from an unknown pleasure and his lover feeling utterly helpless always excited her.
"How is it? Do you still feel like resisting? Or... have you already surrendered, just like this cock?"
Even though the match was already over, she continued to press them for perfect subjugation. Every time his "female switch" was flipped, the husband reached a submissive climax, semen leaking from his cock.
The wife felt miserable watching him, but then she realized something as a Lust Demon's hand reached out from behind her. She was dripping vaginal fluid while watching her husband being ravished.
As the persistent touch of the Lust Demon traced her breasts—which were so familiar with her husband's hands—and the crack between her legs, she moaned like a virgin.
It felt better than when she first learned to masturbate, better than when she met her ideal man... Perhaps it was the sense of depravity from this irrational situation, combined with the Lust Demon's expert touch.
Unable to overcome the demon's handiwork, the wife met a spine-tingling climax as a deep kiss covered her lips. Squelch. The fluid that sprayed from between her thighs splashed onto her husband's face.
"A wife who gets excited watching her husband being taken, and a husband who gets excited watching his wife climax at someone else's hand♡
I see now. You weren't a pair of womanizers; you're just a couple of hopeless masochistic trash♡ But don't worry. We're a kind race♡ You can both live here as slaves for us♡ How about it?"
She asked the question, but she didn't stop moving for a second. Their consent didn't matter. The original goal of "correction" didn't matter to her either.
The only thing driving her was the pleasure of toyed with her prey.
"See this? This happy face? I'm going to keep taking you every day. I'll make your husband reach a submissive climax right in front of your eyes over and over again♡"
She grabbed the husband's slack, defeated face and showed it to the wife. For a moment, the couple's eyes met.
Then, something touched the wife's buttocks. She flinched and looked down to see the Lust Demon's thick tail—larger and thicker than her husband's.
If a mere finger could provide this much pleasure, then if something that thick entered her... she couldn't win. Realizing this, what she had to say was all too clear.
"Please... take my husband..."
"Ahaha♡ Did you hear that, Oppa? Your wife just abandoned you because she lost to her own lust♡ But it's okay. Karin will take good care of you from now on♡"
Jaejin watched from a distance as the couple was so easily brought to ruin.
"Well, it's not always like that. I might have to give Karin a warning one of these days. So, what are your thoughts?"
Thoughts. Did he even have thoughts? Should he say they seemed to have a screw loose, as expected of the Lust Demon Race? Should he applaud them for successfully breaking a couple? Or...
"It was... incredibly arousing..."
"Look at this one. You were getting excited watching that? You little pervert♡"
Sitri smirked as she noticed the pre-cum dripping onto the floor, unable to be absorbed by his clothes. What man wouldn't be excited watching such a depraved, dopamine-fueled scene?
"Yes, I understand how you feel, Son-in-law. A man is a creature that can survive for months on a single picture of a woman's body. So it's not strange for you to be excited."
Sitri whispered in his ear, speaking for every man who had just seen something erotic. She leaned in, pressing her body against Jaejin's.
Rub, rub. As her hand began to stroke his cock through his clothes, Jaejin let out a soft moan, forgetting they were in a hallway.
As the sound echoed down the corridor, the inmates locked in solitary confinement began to turn their attention toward the noise.
"Now, can you feel it? The gazes of jealousy and envy directed at you♡"
Before long, everyone in the surrounding cells was watching. They were awestruck by Sitri's presence, but then they noticed the man beside her.
A man who was about the same height as her, but with a cock that couldn't even be compared to theirs.
The way she treated him was different, too. The way she pressed her body against him, stroking his cock so tenderly while looking up at him, made them look like lovers, not a warden and an inmate.
"Understand this well. No matter how much of a pervert or a masochist you are, you are not prey like those men. To them, you are a being like Karin♡"
She slowly lifted his clothes, displaying Jaejin's long cock—hidden behind the curtain of his garments—to the inmates. It was a size that even a man would admire. But cruelly, that cock was pointed toward their idol.
"This is all part of broadening your horizons, after all♡"
Stroking the cock that was so erect it seemed to pierce his lower abdomen, its veins bulging, Sitri pressed her lips against Jaejin's.
