Volume 1 Chapter 12 Koharu’s Service of Gratitude
Edited by: Kanaa-senpai
”Hirose-kun! Oh, Hirose-kun, please! More!”
”Hirose… I need more… more, please!”
Stretched out on the bed, Hirose was flat on his back, a willing anchor. Above him, two girls swayed and rocked, shifting their bodies in a rhythm that was both desperate and perfectly synchronized. Koharu pressed her weight down, holding him close, her muscles clenched around him with intense, shuddering control. Her breath came in short, ragged gasps against his ear. Meanwhile, Hibiki was coiled above his head, her hips moving with a hypnotic, grinding intensity that pressed the soft, warm skin of her inner thigh against his cheek.
He reached up, his fingers digging gently into the pillows. Every breath was a struggle; the pressure was heavy, overwhelming, yet fundamentally right. He was drowning in sensation—the warmth of their skin, the scent of their rising excitement, the sound of their ragged breathing filling the small space. It was agony and glory combined.
My heart… I can’t think!
The world had narrowed to the exquisite pressure points where their bodies met. He was the focus of their combined, escalating need.
”This is it… I’m gonna… I’m gonna lose it!” Hibiki gasped, her voice raw and thick with emotion.
”Me too! Koharu, let’s go together!”
”Hibiki-chan!”
”Koharu!”
The two best friends cried out each other’s names, their hands finding each other and clasping tight as they picked up the pace. They were pulling him upward, driving him toward a destination he couldn’t stop. Hirose, groaning, knew he was being utterly consumed, but it was the most beautiful consumption imaginable. Steadily, breathlessly, they climbed the staircase to their shared peak.
And then, they reached their paradise. The tension shattered in a unified explosion of feeling.
””Nghhhhhh—nnnnggghhhh!!“”
”Foogghh—hhgghh!?“

Hibiki and Koharu. Hirose, completely stunned by the fact that he was now in a full-blown harem situation, nevertheless had to accept it. Cornered by the two girls, he’d used his Gift on himself, which only made them push more pleasure onto him, leading him to climax over and over. Even with a light application of his Gift, when it was two girls against him, even the mighty Hirose had no defenses.
So, they gorged themselves on each other’s bodies, pushing their desires until the bedsheets were completely soaked and the girls were finally satisfied.
”…Having three people might not be so bad after all…”
”Hey, put yourself in the single person’s shoes for once,” he muttered, exhausted.
The three of them cuddled together on the cramped single bed, lined up like the characters in the word kawa (river). Hirose was in the middle, Hibiki on his left, and Koharu on his right. The two girls, who were the least tired, squeezed his arms tightly between their own hands and breasts. The girls on either side of him smiled at each other, their hair messy and wild, clearly happy with how things had gone.
Hibiki was surprisingly pleased with their slightly unconventional play session. The fact that her best friend, Koharu, was part of it was a definite plus.
”Hibiki-chan… inviting me to join was nice and all, but I have a feeling I’m going to end up falling in love with Hirose-kun now…” Koharu confessed softly.
”The moment that happens, it happens, right? Hirose, you better start earning a paycheck!” Hibiki declared playfully.
”What are you even saying!?” Hirose gasped.
”You’ll have to support both of us together~”
”D-don’t be ridiculous, you two…”
Polygamy is illegal in modern Japan. Even though the rise of Dungeons has created high-earning Adventurers who allegedly do whatever they please, it’s still not generally accepted—that hasn’t changed since the old days.
”It’s all up to how the people involved feel, isn’t it?” Hibiki reasoned.
”And wait… we’re already talking about marriage?” Hirose questioned, still reeling.
”I can’t think about anyone but Hirose, after all~” she cooed.
”It’s great that you say that, but…”
These days, Hirose was finding himself thinking, Well, if my girlfriend Hibiki is okay with it, then it must be fine. But the truth was, he still wasn’t quite sure how Koharu really felt.
”Alright, now that we’ve rested, let’s go for another round, shall we? Koharu!” Hibiki chirped, all business.
”Ah, y-yes…!” Koharu agreed, still surprised.
”My opinion?” Hirose asked meekly.
”As if you have one?” Hibiki shot back with a giggle.
”Oh, come onnn…”
That day, Hirose was squeezed drier than he had ever been since he met Hibiki.

Four weeks had now passed since he first began applying his Gift’s treatment to Koharu.
That morning, as she stripped off her pajamas to take a shower before school, she stepped into the bathroom.
”…………Ah.”
Kushima Koharu looked into the mirror mounted on the bathroom wall and her legs gave out, causing her to sink to the floor.
”…Gone… It’s gone… here, and here, too…!” she whispered in disbelief.
Her arms, her stomach, her thighs… and her face. She spun around and turned her rear to the mirror, and even there, they were gone.
The bruises had vanished.
Every single bruise on her entire body was gone. Not a single trace remained, as if they had never existed. Her skin was pure white and flawless. Moreover, her skin was even smoother and more radiant than before. It was a beautiful texture, nearly as perfect as Hibiki’s current skin.
”Ah… Ah… I’m…”
Hugging her own body tight, Koharu remembered her past.
Koharu was a rare case who had understood her Gift before she was even appraised at sixteen. Because of it, she had thrown herself in the path of violence from a young age, desperately trying to keep her mother and little brother from getting hurt. She hadn’t felt the pain while her own Gift was active, but with every occurrence, the number of bruises increased.
Naturally, she stopped showing her skin to anyone. She could never wear a short-sleeved shirt outside, even on a hot summer day, and she always wore black tights whenever she wore a skirt.
”It’s okay now… From now on… I can dress up however I like… I can show my bare skin… I don’t have to worry about people looking at me anymore…!”
How agonizing had that been? Now that she knew all that sadness and all those sacrifices were over, Koharu wrapped her arms around herself and let out a torrent of grateful tears.
* * *
That afternoon, Koharu visited Hibiki’s house. Hirose was there, too.
Then, she stood before the two of them wearing only her lingerie.
”Koharu… you’re so beautiful!” Hibiki gasped, genuinely admiring.
”Yeah… you’re really beautiful, Koharu,” Hirose agreed softly.
The moment she heard those words, tears welled up in Koharu’s eyes once more.
Has there ever been anything this wonderful? Have I ever felt this grateful to anyone? There weren’t enough words in the world. She had already given up on so many things in her life.
”Hibiki-chan… thank you for introducing me to Hirose-kun… And Hirose-kun, thank you, truly, for healing me…” Koharu wept, conveying her deepest thanks.
”Koharu…” Hibiki murmured.
As Koharu delivered her heartfelt thanks, Hibiki leaped forward, fully dressed, and hugged the lingerie-clad Koharu tightly.
”…Well, then! Today calls for celebration sex, doesn’t it!” Hibiki announced, pulling back.
”Huh?”
The tears in Koharu’s eyes dried up the moment Hibiki demanded that she return the favor of her gratitude.
”Since you’re already in your underwear, we might as well go all the way, right? Besides, you’re wearing contacts today, and you’ve gotten so cute…” Hibiki teased.
”B-but… I wasn’t planning on anything like that today…” Koharu stammered, flustered.
”Oh, come on now… To me, that looks exactly like battle lingerie!” Hibiki smirked. “You need to let Hirose touch you properly.”
Today, Koharu wasn’t wearing her glasses; she wore contacts, and her purple lingerie had an erotic atmosphere, with very little fabric.
Hibiki didn’t wait. She took the lead, quickly stripping off her own school uniform. Then, before Koharu could even process it, she unhooked her bra and slid off her panties.
”Hirose… what do you think? I’m pretty sure the Gift’s Effect is showing now…” she purred.
”Ah… no… well… it’s amazing, actually…” Hirose admitted, blushing.
”Why are you acting shy! Look closer!” she demanded.
”Wapuh!?“
Hibiki immediately forced Hirose to sit on the floor and shoved her breasts right into his face. Trapped between the marshmallow-soft mounds of flesh, Hirose could only mumble, his words muffled. Hibiki ruthlessly pressed her chest against his face again and again.
”Phew… Just a moment, Hibiki…” he gasped out.
”So, what’s your impression up close?” she questioned.
”…They look like they’ve gotten… better color?” he wondered aloud.
”See! You noticed! I knew they were changing!” Hibiki cheered.
Just as Hirose pointed out, the color of Hibiki’s nipples had changed. She’d always been on the darker-pigmented side, but now the color was fainter, exactly the shade Hirose preferred. What’s more, the Gift’s Effect had made her entire breasts exquisitely smooth and soft to the touch.
”And by the way, down here too.”
”A-are you serious!?”
Hibiki moved her hand down to her lower half and showed him that her private parts had also changed color, becoming just as beautiful. Even the confident Hibiki blushed slightly, perhaps feeling a little shame.
”Oh, Koharu, you should show him yours, too! Though, you’re already light-colored, aren’t you? I’m jealous~”
”Hibiki-chan… talking about the color of those things is embarrassing,” Koharu whispered, flustered.
”You like lighter ones too, don’t you, Hirose?” Hibiki pressed.
”Uh? Yes, I… I do,” Hirose admitted.
”See! I told you!”
”Even Hirose-kun is doing it now…” Koharu mumbled shyly.
Hibiki, taking charge, sat down on the bed and beckoned to them. Hirose and Koharu exchanged glances and sighed lightly.
Neither of them really disliked the idea. It was just that the atmosphere was so bright and casual—they’d both been hoping for something a little more romantic.
But they approached Hibiki nonetheless.
”Come on, come on. Hirose is the only one still in his uniform,” she urged.
”Alright, alright… I’ll take it off, just wait,” he relented.
At her words, Hirose stripped out of his uniform, leaving only his underwear. He glanced over and saw Koharu shyly removing her bra as well. Seeing her, Hirose couldn’t hold back anymore. Blood rushed to his lower half, and he pressed his hand over the bulge.
”Why are you hiding that~” Hibiki chided.
”Just… habit, I guess?” he replied.
”Well, it’s fine, since you’ll be taking that off soon anyway.”
Hirose knew that, but he was still embarrassed.
Once they were ready, Hirose climbed onto the bed. The girls’ eyes seemed to change color, their focus sharpening. At the same time, a warm scent of female excitement teased his nostrils.
”Hirose-kun… I owe you so much gratitude that words can’t express… so today, I’m going to serve you a lot!” Koharu declared, her voice filled with passionate intent.
”K-Koharu…”
”I’m not going to lose! I’m going to serve you a lot too, so you better be ready!” Hibiki taunted him.
”You’re both getting way too into this… I feel like nothing’s going to change, since I’m always the one being served anyway.”
”It’s fine, it’s fine, don’t worry about it! Koharu and I are both super grateful, so Hirose, you don’t have to do a thing!” Hibiki insisted.
I’m a lucky man… that these two adorable girls would do all this for someone like me… No, if I say ‘someone like me,’ Hibiki will get angry.
”I understand. Thank you…”
Immediately, Hibiki and Koharu grabbed his arms and threw him flat onto his back on the bed. Looking down at him, they were both nude, showing off the glistening, beautiful skin he had perfected. Hirose swallowed hard, and his lower half swelled even further.
”Alright, Koharu?”
”Yes… I humbly accept…!♡”
Excitement evident, both girls descended upon the utterly thrilled Hirose simultaneously, eager to devour him.
That day, Koharu served Hirose even more actively and passionately than Hibiki. As if saying, No matter how much I serve you, it’s not enough to cover my gratitude… she was aggressive and willing to do anything.
Her dedicated posture of service was so erotic that Hirose’s recovery time was abnormally fast that day.
Naturally, Hirose was ultimately squeezed dry until he passed out, sleeping until it was time for him to go home, while the two girls remained full of energy.
