Chapter 155: Lingering Regrets
Chapter 155: Lingering Regrets
With every thrust of Jaejin’s cock, Erdia’s body twisted in a paroxysm of pleasure. Even the sensation of him pulling out stimulated her erogenous zones, forcing gasps and moans from her lips.
Erdia reacted to his every move, her body betraying her instincts as a female. Her behavior gave Jaejin the distinct impression that he was dominating her through pure sensation.
Having found his rhythm, Jaejin carefully managed his urge to ejaculate. He drove his cock deep and fast, relentlessly battering the walls of her vagina.
"Husband... your cock... it feels so good... Hngh, ahhh...!"
Ten minutes had passed since he first entered her, and Erdia had already reached climax several times. She was helpless against the sensation of the thick cock stretching her inside and then sliding out, sending her over the edge again and again.
But the greatest pleasure came from the intense exhilaration of mucous membrane meeting mucous membrane, of skin mingling with skin.
The physical connection was so profound it made her feel truly happy, leaving her body as paralyzed as the very first time she had discovered masturbation and orgasm.
This was different from their previous encounters, which had been driven solely by the need to sate her sexual desire. It was a level of fulfillment far beyond the times she had desperately devoured Jaejin while he lay on the bed, trying to fill the hole in her heart by connecting with him.
Perhaps it was the power of the word she kept repeating: Husband. By using a term reserved for those who have promised their futures to one another, she found herself even more immersed in the act.
Jaejin desperately held back his ejaculation as he watched Erdia, who was more focused on their intimacy than ever before. To him, today was a special day for her.
It wasn't just because she was becoming a Lust Demon; it was because today was the day she could finally say a complete goodbye to her past.
Erdia still felt a deep-seated guilt whenever she thought of her late husband. Jaejin hoped that today, she would break ties with that past and find a new kind of happiness.
Believing that such a pivotal moment shouldn't be cut short by a premature ejaculation, Jaejin exercised maximum restraint over his surging desire, maintaining long, deep strokes.
"Husband... more... more... ♡"
There was one more thing: right now, Erdia wasn't truly looking at Jaejin. Her mournful cries of "Husband" sounded like they were directed at him, but in reality, they were drifting hollowly into the void.
To escape the guilt of her husband's death and the shame of her moral decay, she was projecting the image of a fictional husband onto Jaejin.
There was no guarantee that becoming a Lust Demon in this state would improve things. In fact, there was a risk her twisted desires could awaken in a negative way.
‘So, give it everything you’ve got.’
Jaejin recalled Lena’s advice. Having already realized through conversation that Erdia was suffering from loneliness and a sense of alienation, Lena had left Jaejin with a word of encouragement.
‘Your voice is very persuasive, Jaejin. I’m sure it will reach Erdia’s heart. I guarantee it.’
Jaejin, who trusted Lena more than he trusted himself, didn't doubt her words for a second.
With her legs spread in an M-shape, Jaejin wrapped his arms around her thighs, holding them firmly as he lunged his cock inside even more forcefully than before.
Jaejin was a man with masochistic instincts, weak enough to be ruthlessly devoured by Erdia even when she was human. However, in one area, he was world-class: his cock.
That exceptional organ, coupled with the sense of urgency that he had to achieve a result, created a masculine synergy that was uncharacteristic of his usual self.
Thud, thud. Thud, thud. The pleasure of his lower abdomen slamming against hers. The forbidden ecstasy—something a human woman should never know—of the glans firmly pushing against the vaginal wall and softly pressing the womb beyond it, surged up Erdia’s spine.
"Kh...!? Ahhhng! ♡"
Thump, thump. Controlling his strength to avoid hurting her while relentlessly pushing her to the limit, Jaejin saw Erdia finally beginning to wake from her fantasy.
"It feels so good... ♡ Husband, I love it... I love it... ...?"
The sorrowful, tear-filled look in her eyes gradually gave way to a spark of life. Her clear, soulful brown eyes showed that she had finally emerged from her long reverie and was focusing on the man in front of her.
Jaejin embraced her while still buried deep inside. Though the height difference meant he was technically looking up at her, he couldn't resist holding her close.
"It’s okay now... I have many people with me, so I can’t be by your side every second, but I won’t leave you lonely like this anymore..."
"J-Jaejin...? What are you saying all of a sudden..."
Erdia was slightly flustered by his actions, but as she reflected on her own behavior, she realized what had happened.
She had been so caught up in playing house with Jaejin during the act that her memory was a bit hazy, likely starting from the moment she received the first ejaculation on her face.
Whether it was due to the aphrodisiac effect of the semen or not, she knew well enough that she hadn't been in her right mind for a while. It was likely due to the lingering regrets she couldn't let go of.
Jaejin’s expression shifted from a worried frown to a bright smile when he saw she had returned to her senses.
Yet, his honesty—the way he moved his pelvis and lifted his hips, unable to hide his remaining sexual desire—made her let out a giggle even as she moaned with pleasure.
"Hehe, did you really want to do it with me that badly?"
Her face had returned to that of the elegant yet high-libido widow he knew. Casting aside the mask of the submissive wife, she pushed against Jaejin’s light frame and rolled onto her side.
In an instant, the position shifted from missionary to the cowgirl position, and Jaejin felt his heart race. It was a position he knew all too well.

The cowgirl position, which always reminded him that he was a masochistic male who would lose to a mere human despite having the power of a Lust Demon, made Jaejin’s cock throb with a rock-hard erection.
Just as a completely new second round was about to begin, Erdia whispered tenderly to the man beneath her.
"Even if it’s just for tonight... would you accept me as your bride?"
She held out her left hand, where a ring still sat on her ring finger. That symbol of her past love was slid off by Jaejin’s hand—the hand of a different man.
"No, not just for tonight. From now on, Erdia, you’re my woman."
Of course, she would be one of several women, but there was no need to be so tactless at a moment like this.
Erdia knew the truth without him saying it, but she gave him the brightest, most radiant smile he had ever seen.
"Yes... ♡"
The act, decided by their own mutual will rather than an external agreement, felt distinctly different to both of them.
Erdia looked down at him, her eyes filled with genuine affection rather than a performance. She began to move her body, feeling the cock pressing into her lower abdomen with her entire being.
Her vagina, already loosened by numerous climaxes, moved smoothly even as it took him in to his maximum depth.
Though she seemed breathless, she moved her body to satisfy her overflowing lust and to make Jaejin feel good.
Squelch, squelch. The lewd sounds from the point of insertion began to pick up speed. Forgetting her initial goal of receiving an intravaginal ejaculation to become a member of the Demon Race like her beloved Jaejin,
her movements followed the instinct to share love through their joined bodies, quickly driving Jaejin toward ejaculation.
More than the tightening of her vagina, the fact that Erdia was rocking her hips while their fingers were interlaced made Jaejin even more aroused.
Without needing to lean on the depravity of touching a widow, the thrusting continued as they thought only of each other, soon reaching a crescendo.
"Erdia, I’m going to cum inside...!"
"Yes, give it to me... Darling! ♡"
Thud, thud. To match the moment of climax, Jaejin thrust upward from below. Erdia let out a cry as she felt his glans, pushed to its limit, drive deep into her.
As the climax neared, Erdia’s vagina constricted, beginning to wring his cock. Squeeze. The grip was like a hand tightening around him, and the semen began to surge upward all at once.
Splurt, spurt! The semen erupted with the force of a waterfall, flowing directly into Erdia’s womb, which hadn't received a man’s seed in years.
"Ahhh... Hngh... ♡"
She met her climax with a face that looked pained yet incredibly happy. Unable to even speak, Erdia’s body bucked repeatedly as she peaked.
On her lower abdomen, which bulged slightly from his cock, Jaejin’s Lust Crest was now engraved as if it had always been there.
The Lust Crest announced its presence with an eerie red glow. The change was instantaneous. As Jaejin’s semen entered her, the first thing she felt was a surge of power.
Since Erdia was not a combatant, the increase was slight, but the vitality coursing through her body was enough to make the effect clear.
The next effect of the Lust Crest appeared in her lower body. Despite being impaled by that long cock like a skewer, the painful pressure in her abdomen she had felt before had vanished.
As if her body had been redesigned to accept a cock, the rest of Jaejin’s length, which had been left out, was now buried in her vagina all the way to the root.
While still in the afterglow of her climax, Erdia felt an intense sexual impulse that far exceeded her previous libido, yet she felt confident she could control it better than before.
Through these changes, Erdia realized she had become a Lust Demon, but the joy she felt was less about her transformation and more about the fact that she was now truly connected to Jaejin.
And now, looking down at Jaejin, who was lying beneath her trying to soothe his sensitive body after ejaculating, she felt she could tease him even more skillfully.
"Kh... E-Erdia...?"
"We’re finally one, Husband. ♡ You haven't had enough yet, have you? This time, I’ll be the one serving you. ♡"
She began to gently squeeze the glans that was touching the entrance of her womb. Erdia was performing feats impossible for a human as if they were second nature.
Showing an incredible level of adaptation for someone who had just become a Lust Demon, she looked down at the moaning, helpless Jaejin and smiled.
"I’ll be in your care from now on, Hus-band. ♡"
The long schedule at Capia Castle was entering its final stage.
