Upon arriving at the Kozuki residence, the site of the disappearance, Shugo is surprised to encounter Kozuki Kazuna, as she has the same face as his former lover and her twin sister, Kozuki Yura. Kazuna begs Shugo to find her sister, but their father, Kozuki Keiichiro, declares bluntly, "My daughter is already dead."

[Before the figure sculptor who had settled in the remote island cosplay resort “Costaria” appeared... A pair of voluptuous and busty cosplayers, the “Ikura Sisters”!]
I, Aizen Tsukuru, am a figure sculptor.
When it comes to enhancing the charm of 2D characters to 3D, I refuse to make any compromises. That’s why my rigorous approach to figure creation has been highly praised.
In my pursuit of perfection, I arrived at my ideal paradise— “Costaria”. It was so comfortable that I spent so much time working there and before I knew it, people started calling me a “resident of Costaria."
However, a trial soon came my way.
"A cast-off... erotic figure?!"
As a virgin, I had no real knowledge of the female body, which prevented me from creating figures that truly satisfied me.
I was at a loss, feeling like a failure as a professional. But then, appearing before me were the Ikura sisters— two girls that just made their debut, wrapped in dazzling cosplay outfits that accentuated their voluptuous, dynamite bodies.
"Please, make a figure of me using your hands!"
Is this really happening?
Those voluptuous, perfectly curvy bodies— it's as if they stepped right out of my imagination.
Dressed in provocative cosplay outfits, can I really go ahead and create the ultimate erotic figure with them?!"
My first summer vacation after enrolling at Shinpoku Academy— Mom became pregnant with my best friend's child.
“Ahh... oh, yes, Nagi-kun! Harder, faster! Pound the entrance to my baby-filled womb with your cock!”
Right before my eyes, my mother—Nishino Riho—is being held by my best friend, Terashima Nagi. My gentle, beloved mother is moaning, leaking a lewd, feminine voice unimaginable from her usual self, enjoying sex with my best friend Nagi's young penis.
Why? How did this happen? When did Mom and Nagi become intimate enough to have sex? Why is Mom pregnant with Nagi's baby instead of Dad's? I don't understand any of this.
No, I don't want to understand. As if to flaunt it to me, helpless and consumed by despair, Nagi thrusts his hips vigorously, taking my mother. My beloved mother, the most important person to me, has been taken by Nagi.
My gentle mother's eyes no longer look at me. They only look at Nagi. I can't forgive Nagi for having sex with Mom countless times behind my back and getting her pregnant! But Mom doesn't seem to mind in front of me.
Worse, she's accepting Nagi's penis with an expression of pleasure I've never seen before. Anger, hatred, despair... Amidst this jumble of emotions, I found myself intensely aroused by the sight of my mother, pleasured by my best friend, my own penis swelling with rage.
Nishino Riho is young, beautiful, and gentle. She possesses a voluptuous figure men adore—103cm I-cup breasts and a 99cm ample rear.
This mother cuckold story depicts how she betrayed her husband and their cherished only son, the protagonist “Nishino Ryota,” to drown in sex with Nagi, ultimately conceiving Nagi's child within her womb as a woman.
Driven by her lust, Riho surrenders to Nagi, a young, virile male brimming with sexual desire. Today, too, she steals glances from her beloved husband and son, drowning in carnal passion as she ripens.
One day, I lost something precious.
I went to several cosplay events, and took some pictures to satisfy my lust. However, the camera that contained all the pictures was destroyed in an unfortunate accident.
Perhaps they didn't want to see my cry anymore, the Yamakake sisters, Sana and Yua, who were involved in the accident, said to me;
"Would you like us to cosplay for you instead?"
I accepted their offer.
Their bodies look lewder than anything that I have ever seen in any erotic manga, and they were willing to be my very own cosplayers!!
I put the skills I learned as a fashion student and my hobby of making costumes for dolls to good use, creating costumes for the sisters, and as luck would have it, I was given tickets to the cosplay resort "Costaria", located on a remote island.
This was an opportunity for me to get the best portraits in Costaria. However, what awaited me on that island was so much more than I could imagine!
"Let's have a different kind of cosplay today."
"Erotic role-playing. You'd like that, wouldn't you?"
The sisters whispered those words to me.
With my very own cosplayers, I'm going to make extreme and intimate portraits that cannot be shown to anyone.
I wonder if it's okay to make them──
The protagonist, Kazama Yukiya, was living a student life while earning money through his own method of exorcism and purification, in addition to receiving financial support from his parents. One day, men in black suits appeared at his place and forcibly took him back to the countryside. They were the messengers of the "main family", and Yukiya is informed by the head of the Kazama family at the mansion where he was taken that Hisame, a shrine priest he had adored like a real brother since he was young, has passed away.
Astonished, Yukiya is immediately told by the family head, "Become the shrine chief to protect the company and take on 'a certain troublesome matter' with the shrine maidens. You have the talent for it." Confused, Yukiya hears about the "troublesome matter" from the three charming shrine maidens and reluctantly accepts the task.
They Get Stronger Every Time They Drain You! Retrain Five Hopeless Succubus Girls Through… SEX!?
You want me to retrain FIVE utterly hopeless succubus girls!?
The name’s Glenn Magna. I’m an S-rank adventurer who’s cleared countless high-difficulty quests—and to put it bluntly, I’m a man who’s been through a lot. Time and time again, I’ve been saddled with impossible quests under the lame excuse that "You’re the only one who can do it!" After years of being everyone’s errand boy, I finally hit my limit.
"Isn’t there an easier way to make a living...!?"
That’s when inspiration struck. Instead of being the one doing the grunt work...
"Why not become an instructor and raise a party strong enough to do it for me?"
While continuing my career as an adventurer, I started working as a guild instructor. But one day, the Guild Master handed me the most ridiculous request yet.
"Please... just do something about those girls!"
The party he assigned to me consisted entirely of succubi—and they were a complete disaster. Terrible with swords. Hopeless with magic. They’re so incompetent they’ve never even managed to clear a beginner-level quest. They’re the most spectacularly useless party of succubi anyone has ever seen.
But succubi possess one unique racial trait. By using their “Semen Absorption” ability, they can absorb highly concentrated life essence through naughty acts, dramatically boosting their individual power.
And, by an incredible stroke of luck... (or terrible luck?) I just so happen to possess an incredibly rare body overflowing with the highest possible concentration of life essence.
"Instructor Glenn's... semen... it's incredible...!"
"To think... it can become our strength...!"
Train them through SEX. Fight through SEX. Deepen their bonds through SEX.
Can this hopeless band of succubi grow into a legendary adventuring party?
The goal is simple: Raise an elite team capable of handling dangerous jobs on their own!
Until then, the legendary adventurer's hardships are far from over...
