Volume 4 Chapter 17 The Two of Us Together: A Shared Revelation of Pleasure and Desire
Edited by: Kanaa-senpai
The room was thick with tension and unspoken emotions as Rio, still weak and flushed from her earlier experience, stammered at the sight of Aoi standing before her. “Ah, A-Aoi… why are you here?” ¹
Aoi’s presence was both comforting and unsettling, her expression unreadable as she approached the bed. “Rio… you did so well, didn’t you?” she murmured, her voice soft but carrying an underlying intensity.
”Ahh!” Rio gasped, her body tensing under the weight of Aoi’s gaze. She felt exposed, her vulnerability laid bare as Aoi climbed onto the bed and embraced her, the towel barely concealing her trembling form.

(Wait, that makes it sound like I’m the one who did something wrong, doesn’t it!?) Rio’s thoughts raced, her mind struggling to process the situation. Aoi’s phrasing made Hirose feel a twinge of guilt, though he knew he had done nothing wrong. It was Rio who had invited him, and he had merely accepted her request.
”I was watching from the next room the whole time, you know,” Hirose admitted, his voice calm but laced with a hint of defensiveness.
”A-aah… ngh… that’s so embarrassing!” Rio moaned, her face burning with shame. She had been unaware that Aoi had been observing her treatment, her most intimate moments laid bare for her friend’s scrutiny.
Aoi’s knowing smile revealed that she had indeed been aware of Hirose’s contact with Rio. Whether through woman’s intuition or careful planning, she had coaxed the details from Hirose and even enlisted Ecoa’s help to monitor the session from an adjacent room.
”Did I… did I become one with Aoi? You don’t hate me, do you, Aoi?” Rio asked, her voice trembling with desperation.
Aoi’s expression softened. “What are you talking about? You’re my best friend, Rio. I could never hate you.”
But Rio’s insecurities ran deep. “But, Aoi, you changed… you became someone I don’t recognize, and you moved away…” she whimpered, her voice breaking.
”I admit I changed,” Aoi acknowledged. “But… you understand why now, don’t you? Hirose-senpai’s hands have a way of revealing truths.”
As Aoi’s words sank in, Rio’s resistance began to crumble. She was starting to comprehend the reason behind Aoi’s transformation, the source of her friend’s newfound confidence and radiance.
”Ngh, u-uuuh… I… I feel so good! Waaah!” Rio cried out, tears streaming down her face as the realization hit her. Aoi simply patted her head, a gesture of comfort and understanding.
Rio had finally accepted it: Hirose’s touch had awakened a pleasure within her that she couldn’t deny. Her tears were not just of embarrassment but of self-recrimination, for she had always viewed Hirose as an enemy, and now she had surrendered to his skill.
After a few minutes of silent contemplation, Aoi announced, “Rio, you must be tired. Just watch from here.”
”Aoi? What are you going to do?” Rio asked, her voice laced with trepidation.
Without a word, Aoi began to undress, her school uniform falling away piece by piece. She tossed the clothes onto the corner of the bed and approached Hirose, who sat silently, his expression unreadable.
”Rio, watch me, okay? Watch how much I love Senpai…” Aoi’s voice was a whisper, but it carried across the room, filled with intent.
”A-Aoi…” Rio gasped, her heart pounding in her chest.
Aoi’s plan was twofold: to comfort Rio and to help her understand the true nature of pleasure. By showing Rio what they did, she hoped her friend would grasp the depth of her feelings for Hirose and experience the same liberation she had found.
As Aoi began to undress Hirose, Rio’s eyes widened. “M-Maybe… did I… excite you?” she stammered, her voice barely audible.
Hirose’s lower body was visibly aroused, a reaction that didn’t go unnoticed by Rio. “I said I wouldn’t touch you, but… a reaction still happens, huh? Sorry,” he murmured, his voice thick with embarrassment.
”You’re getting excited over me… that’s… unbelievable!” Rio exclaimed, her sense of self-worth wavering. She still believed she held no appeal, and Hirose’s reaction was a shock to her system.
”Fufu… it means you have charm, too, Rio. Now, just watch,” Aoi said, her voice gentle but firm. She then kissed Hirose², their tongues entwining in a passionate embrace, deliberately putting on a show for Rio.
(A-Aoi is… amazing… that look on her face…) Rio thought, recognizing the same expression of ecstasy she had seen in the basketball club room. Watching Aoi’s pleasure ignited a fire within her, a burning desire she couldn’t ignore.
As the intimate moment between Aoi and Hirose unfolded, Rio found herself captivated, her body responding despite her attempts to resist. The sight of Aoi’s abandon, her complete surrender to pleasure, was both mesmerizing and terrifying.
When Aoi finally pulled away, she lay down beneath Hirose, her body glistening with sweat. Rio, meanwhile, peeked at the scene with a flushed face, torn between fascination and embarrassment.
Hirose gently caressed Aoi, his hands moving with practiced ease. “Senpai… make me feel good, okay?” Aoi whispered, her eyes pleading.
”I got it,” Hirose replied, his voice hoarse with desire. He kissed her skin, his touch sending shivers down Aoi’s spine. With each caress, each whisper, Rio felt her own body respond, her breath coming in short gasps.
”Ngh… Rio! This is how good it feels… ahh… right there! Senpai is so kind… nngh… sometimes strong… and that’s why it’s the absolute best! ♡” Aoi moaned, her voice a mixture of pleasure and devotion.
”Aoi…” Rio whimpered, her heart aching with a mixture of envy and longing.
As Hirose joined with Aoi, their movements becoming more urgent, Rio felt her control slipping. “Rio, hold my hand… watch until the very end, okay?” Aoi said, her voice a command.
”Ah! Ahh!” Rio cried out, her body arching as she grasped Aoi’s hand, her fingers intertwining with her friend’s.
The scene before her was both beautiful and overwhelming. Aoi’s pleasure was palpable, her cries of ecstasy filling the room. Rio’s own desire grew with each passing moment, her body yearning for the same release.
After what felt like an eternity, Aoi panted, “Ooh! O-ohh! That was dangerous… today, Senpai, you’re just too amazing!”
”S-Sorry… I just couldn’t calm down at all…” Hirose replied, his voice thick with satisfaction.
”S-Sorry… I just couldn’t calm down at all…” Hirose replied, his voice thick with satisfaction. “Now… it’s Rio’s turn.”
”A-Aoi!? What are you saying!?—Kyahh!” Rio shrieked as Aoi, despite her exhaustion, sat up and approached her. With surprising strength, Aoi laid Rio down and stripped away the towel, exposing her trembling form.
”See… your body doesn’t lie. You were taking care of yourself just now, weren’t you?” Aoi teased, her eyes sparkling with mischief.
Rio’s face burned with shame. “T-That was… because… because seeing something like that would drive anyone crazy!” she protested, her voice weak. During Aoi and Hirose’s intimate moment, Rio had indeed found herself pleasuring her own body, her fingers moving in rhythm with their passions.
”I’ll make you feel good with me, too… besides, you want to be one with me, don’t you?” Aoi asked, her voice soft but insistent.
”Ah… ngh… Aoi, that’s unfair… I do want to be one with you! My body is going crazy… and that’s why when I see this person, I get these strange feelings!” Rio confessed, her voice breaking.
Aoi’s smile was triumphant. “Hehe… then I’ll give you a reward first.”
Before Rio could protest, Aoi leaned in, her lips pressing gently against Rio’s. The kiss was soft, a mere brush of lips, but it sent shockwaves through Rio’s body.
(Aoi’s lips… her tongue… ah, no! This is… too pleasurable! Aoi… Aoi!) Rio’s thoughts were a jumble, her mind struggling to process the flood of sensations. Instead of disgust, she felt joy, a deep, overwhelming happiness that threatened to consume her.
”This is my request for you,” Aoi whispered, pulling away slightly. “You need to call Senpai by his name, or at least ‘Senpai.’ Don’t call him ‘this person’ or ‘that guy’ anymore.”
”Au… I understand…” Rio murmured, her voice hoarse.
”And, Senpai, you need to call Rio by her first name, too,” Aoi added, turning to Hirose.
”Is that okay?” Hirose asked, his voice gentle.
Rio nodded, her eyes filled with unshed tears.
”Rio-chan… tell me if it hurts, okay?” Hirose said, his voice tender.
”No… it won’t hurt… so… so please put out this burning in my body!” Rio pleaded, her voice desperate.
At her words, Hirose and Aoi exchanged a meaningful look, their unspoken understanding hanging heavy in the air.
”We’ll make your first time… feel so, so good!” Aoi promised, her voice a whisper.
”Ahh… what’s going to happen to me… this is… I’m already…” Rio trailed off, her body trembling in anticipation.
She was naked, vulnerable, and exposed. Aoi and Hirose loomed above her, their intentions clear. The thought of what was to come sent a strange sweat breaking out all over her body, her heart pounding in her chest.
”Alright, Senpai—let’s do it!” Aoi declared, her voice filled with determination.
”Got it,” Hirose replied, his voice steady.
As they lowered their faces to Rio’s body, she knew there was no turning back. The pleasure they promised was not just physical but emotional, a connection that would bind them together in ways she couldn’t yet comprehend.
”Nnnnnghhhhh!” Rio cried out, her body arching as wave after wave of pleasure crashed over her. She experienced climax upon climax, each one more intense than the last, her first times unfolding in a blur of sensation and emotion.
In that moment, Rio was lost, her body and mind surrendering to the irresistible sea of pleasure that Aoi and Hirose had promised. And as she drifted, her cries echoing through the room, she knew that nothing would ever be the same again.
* * *
It was late May. At Aoi’s urging, Rio underwent a four-week course of treatments. Beyond just the ‘Skin Quality Improvement,’ she requested and received other skill applications based on her own hopes.
The result was a dramatic change in Rio’s body. “Eh… ah… what is this… I’m… so smooth?” In her room, she touched her face and body, leaning close to the mirror, almost kissing her reflection to be sure.
”My hair is silky, too… what is this? Is this really me?” The added effects of ‘Hair Quality Improvement’ and ‘Depilation’ had left her body, from head to toe, completely transformed and stunning. Rio stared at herself with disbelief.
”Eh… is that Kozuka?”
”She looks kinda cute today, doesn’t she?”
”Her hair is beautiful, too… what happened?” As Rio walked into the classroom, feeling a flutter of nervousness, the boys in her class began to stir.
The old Rio had always had a sharp look in her eyes and an unapproachable vibe. But what about today? While the shape of her eyes hadn’t changed, her overall expression seemed softer.
Her skin was lighter, with not a single blemish. Her hair was so smooth it looked like it had been treated with the most expensive product. The change in Rio’s appearance was impossible for her classmates to ignore.
And Rio, who previously only had Aoi for a friend, was approached by girls she had never spoken to before.
”—U-Um…” After school, with her beautification committee work finished, Rio—still in her tracksuit/jersey—called out to Hirose, and the two were left alone.
The setting was the storage room for gardening tools, which was also used as a small gym storage area, with a high-jump mat resting nearby.
”I… I was called beautiful and cute for the first time in class today…” she confessed, looking shyly at Hirose and telling him about the day’s events.
”I see. That’s great… it means all the effort was worth it. And is that a side ponytail? It really suits you.”
”N-No… er… thank you…” Rio had never styled her hair before, but Aoi had called her today and insisted she wear her hair in a side ponytail with a scrunchie, saying she should make the most of her new beauty.
”No, not just ‘thanks’ for that! I wanted to thank you for making me beautiful… so… thank you…”
”Yeah… same here,” Hirose responded. Rio was so embarrassed she couldn’t meet his gaze.
After that initial treatment, Rio had her first time with Hirose under Aoi’s guidance. Even during subsequent treatments when Aoi wasn’t around, Rio would stop Hirose from leaving and continued to sleep with him. Yet, Rio still struggled to fully open her heart. Though her body craved Hirose, her mind was in conflict.
After four weeks, however, her feelings began to shift. “Um, well… I’m going to properly greet your girlfriend soon, Senpai… so… today, will you make love to me?” she asked.
Saying this, Rio pulled down the zipper of her tracksuit/jersey. Hirose swallowed hard and stepped closer to her. “I… I haven’t been able to control myself lately…”
”I know… you’ve made me crazy so many times.”
”Then, are you still okay with that?”
”Yes… I want you to touch me a lot, Senpai…” Next, she dropped her tracksuit pants, revealing stained underwear. “Tell me if it hurts.”
”It’s okay if it hurts…” Rio insisted. Hirose reached for her body. And with that, the two lay down on the mat—
”Ah! I came when Rio messaged me! How many times have you two done it already?!” About an hour later, Aoi, who Rio must have messaged sometime earlier, showed up and pouted at the disastrous state of the room.
”Aoi… no… I can’t hold out alone… so—”
”Haha… I just finished club practice, and I’m tired, you know… Wait, Senpai!?” Hirose strode toward Aoi, who was standing at the entrance, and forcibly laid her down on the mat where Rio had climaxed.
”W-Well, I’m covered in sweat…”
”I like your sweat, Aoi-chan. See, before, you purposely wouldn’t wipe it off, right?”
”I-I get it… Senpai… it’s hot…” Aoi was still wearing her sports gear. Understanding her meaning, he stripped it off her. Hirose’s ever-increasing libido was starting to trouble his girlfriend, Hibiki.
The reason for this would be revealed later by Ecoa, but Aoi and Rio hadn’t been told yet. That’s why, even after having Rio alone, Hirose still had plenty of energy—
”—Senpai, you can completely wreck me, okay? ♡” At Aoi’s provocative words, Hirose utterly devoured her, just as she had asked.

Driven by a fierce desire to share Aoi’s happiness, Rio undergoes a four-week transformation that makes her stunningly beautiful, shifting her from an unapproachable classmate to a desired figure.
This newfound confidence and an overwhelming physical craving lead her to seek out Hirose alone, dropping her guard and giving herself fully to the protagonist’s potent touch. The dramatic shift in her appearance and attitude hints at the powerful magic at play in their steamy love triangle, which ultimately becomes a shared pleasure between the two closest friends and their shared lover.

Character Insight:
Rio’s character arc shifts dramatically in this chapter. Her initial resistance to Hirose wasn’t about repulsion but about a self-perception of worthlessness.
When the Gift-fueled treatment makes her beautiful, and she sees how much Aoi loves him, her emotional barriers shatter.
Her shame-filled crying after her first climax is a crucial moment where her mind finally starts to catch up to the intense pleasure her body accepts. This transformation from tsundere to lover highlights the pervasive power of Hirose’s S-Rank ability and her deep desire for connection with Aoi and him.
—
Behind the Scene:
This intense session between Hirose, Aoi, and Rio marks the full acceptance of Rio into the intimate circle of lovers.
Aoi’s proactive role in having Rio witness the act and actively participate is a deliberate move to help her friend overcome her stubborn resistance and fully experience the joy of Hirose’s presence. The mention of Hirose’s increasing, uncontrollable libido sets up a future plot point—the escalating side effects of his ‘Gift’—which remains a mystery to Aoi and Rio, adding a layer of dramatic irony to their passionate encounters.

Notes:
• Rio – A member of the Beauty Committee who previously worked with Hirose and already holds a negative opinion of him, seeing him as a ‘playboy.’ She has short dark hair and is dressed neatly in her school uniform. She is Aoi’s friend and is currently determined to ‘rescue’ her.
• Ecoa – The Guardian of the Dungeon Core, a beautiful entity with long blonde hair, slit eyes, and distinctive pointed ears reminiscent of an elf. She initially appears in black ceremonial robes, which instantly transform into a revealing, classic black maid uniform. Her existence was previously undetectable by ‘Appraisal’ Gifts. Her sole purpose is to serve and support the Dungeon Master, Hirose.
• Kozuka Rio – Aoi’s best friend. She has a neat, precise look with side ponytail black hair and is slightly shorter than average. She was initially friendless, making her connection to Aoi incredibly important. She is highly suspicious of Hirose and what he’s done to change Aoi, viewing him as a threat.
