Volume 9 Chapter 24 Interlude 1 – Shiori-chan Always Has the Upper Hand ★
Edited by: Kanaa-senpai
The Merchant Guild Kinvale, part of the renowned Big Three, now fell under my ownership after I acquired it. Its top-secret laboratory, guarded by stringent security, was accessible only to me. With a familiar knock, I announced my arrival.
”Is that you, Takumi-kun?” a sweet voice called out.
”Yeah, just wanted to see you,” I replied.
”Come on in! It’s a bit messy, but don’t mind that.”
The magical lock disengaged, and I stepped inside. Shiori-chan, clad in a lab coat, was busy mixing potions. Her neatly trimmed blue hair framed her idol-like features, which now wore a warm smile. Before teleporting into this world, she had been a top student in national mock exams. Her intellect and ‘Formula Refinement’ Skill had earned her a place as the guild master’s adopted daughter—a true winner among classmates.
However, as the guild master’s adopted daughter, our relationship had been constrained. That changed when I took over the guild and she sold herself to me, declaring, “As the guild master, Shiori Kinvale, I take responsibility for selling the historic Merchant Guild Kinvale. I shall become a slave and share its fate.” And so, she gracefully accepted her new role.
I pride myself on being cautious and shrewd, but politically, Shiori-chan is the only one who’s ever outmaneuvered me. Despite her modest chest, she’s a special existence—my owned slave and the last classmate to offer her pure devotion. Another quirk of hers is her passionate voice, reacting with “voices of intense joy♡” or “voices of strong delight♡.” Though, according to Eil-Eil and Kahoru-chan, she’s actually embarrassed by it.
”Shiori-chan, you’re as dedicated as ever. Working on a new potion?” I asked.
”Yes, Master. I wanted to serve you without embarrassment… so I developed a new drug. I was hoping you could help test it,” she said, her cheeks flushing as she tugged at her lab coat sleeve.
Her idol-like charm and intelligence shone in that gesture, and I couldn’t help but stare. “Sure, if I can. What does it do?”
”It heightens embarrassment but suppresses the loud, passionate voice that comes with excitement. When I… get carried away, my voice gets so loud. Afterward, I’m mortified. Even with you, Master, I tried to hold back, but… I couldn’t. So, I adjusted it to let me serve you normally. Would you… test it with me?” She averted her eyes, twirling a strand of blue hair.
Her mix of adorability and intellect made my heart skip a beat. I hadn’t realized how much her passionate voice embarrassed her. “Sounds interesting. I’ll admit, I’ll miss your voice a bit, but I’m excited to see this work.”
”Don’t say that, Master… I can’t sleep from the embarrassment. Here, I’ll take the potion. It acts fast, so observe my service, okay?”
She held up a vial of pale green liquid, downed it in one go, and closed her eyes, awaiting the effect. I sat nearby, watching intently. Shiori-chan���s potions were often unpredictable, but she ensured they were safe—though sometimes overly effective.
”Mmm… Takumi-kun, my body’s warming up… my heart’s racing. I added a mild aphrodisiac, so while I’m embarrassed, my voice should stay suppressed… I think?”
”Great. Let’s begin. Shiori-chan, serve me as your master. Keep it natural, despite the embarrassment.”
She rose, lifting the hem of her lab coat as she approached. Her blue hair swayed, and her idol-like face tightened with nerves. Just this was enough to make my heart race. It felt deliciously wrong.
”Master… I’ll try not to make embarrassing noises. May I lower your pants?”
”Go ahead. I’ll witness your efforts.”
She swallowed hard, lowered my pants, and glanced away briefly at what she saw. Her fresh embarrassment was endearing, but she quickly knelt and leaned in.
”Forgive my disrespect as a slave… mmm… you’re so warm… mmm… I’ll serve you, even if it’s embarrassing♡.”
Her tongue traced softly, the slick sensation wrapping around me. Her gentle movements were a new, tantalizing experience. Usually, it would be filled with “wet sounds, wet sounds, strong wet sounds♡.”
”Shiori-chan, you’re doing great. Your voice is so refined, and your embarrassed expression is incredibly enticing.”
”Uuu… the potion suppresses my voice, but not my feelings… seeing me touch you like this is so embarrassing♡.”
”That contrast is adorable. Keep going. Take me deeply, quietly. And finish by receiving me with your face.”
She nodded, her throat working gently as she took me in. Her ears turned crimson.
”Mmm… ngue, ngue… having my throat caress you like this feels so good… but I’m holding back my voice♡.”
”You’re amazing, Shiori-chan. The potion’s working perfectly. Now, mark you as my slave. Receive me as one should.”
”Yes, use your slave, Shiori… ugh, even declaring that is embarrassing…”
This is Shiori-chan… my idol returned to me! Excited, I pressed her head gently before pulling out and releasing onto her face.
Warm release, pulsing release, warm release♡.
Strong release, strong release, long release, long release♡♡.
White liquid splattered across Shiori-chan’s delicate face, and she trembled softly, eyes closed.
”Aah, Master’s… on my face… it’s so embarrassing, Takumi-kun. But I didn’t make strange noises, right? I held back, right?”
”Yeah, great results, Shiori-chan. Your embarrassed face is adorable. Let’s move on to deeper service, shall we?”
I helped her stand and sat her on the research desk. As I removed her lab coat, her small chest was exposed. She tried to cover it with her hands but quickly gave up, surrendering to me.
”Master… don’t look too much at my disappointing chest…”
”A slave ordering her master?”
”Uuu, Takumi-kun’s being mean…”
”You’re the one who sold yourself into slavery, Shiori-chan.”
”That’s a different matter!”
”No excuses, Shiori-chan. Lift your skirt and show me your secret place like a proper slave.”
She hiked up her lab coat skirt and lowered her underwear. Her damp intimate area caught my gaze, and her face turned even redder.
”I hate being watched like this, Takumi-kun… but as a slave, I have to endure it for service…”
”That embarrassment suits you perfectly.”
My fingers slipped inside her with a soft squish. She braced herself on the desk, hand over her mouth to muffle her voice.
”Mmm… Takumi-kun, that feels so good. You’re touching a slave’s secret place♡.”
”You’re amazing, Shiori-chan. Let’s make love right here on your research desk.”
I lowered my pants completely and pressed my hardened intimacy against her. Her eyes glistened with embarrassment as she nodded. Who is this adorable creature?
I want Chinatsu-chan and Haruka-chan to experience this…! Those two perverts of the McGaref Slave Girls Collection—I’d love to see them squirm with embarrassment! For now, I focused on Shiori-chan.
I thrust deep inside her, her slick tightness enveloping me. I kissed her as I began moving slowly.
”Master’s so big… it’s reaching deep. I’ll hold back my voice…!”
”Shiori-chan’s warmth feels incredible. The potion’s effect is so refined.”
”Uuu… it’s embarrassing, but if it makes you happy… mpf… I’m glad…!”
The desk creaked, and potion bottles rattled. Shiori-chan wrapped her arms around me, reacting softly while gazing into my eyes.
”Takumi-kun, I’m… close…! I’ll stay quiet, holding back my passionate voice. Please reward me with your essence in my secret place.”
”Of course. We’ll climax together, Shiori-chan. Receive me as your slave’s secret place.”
I smirked inwardly at how accustomed I’d become to treating classmates as slaves. This kind of intimate connection had become normal—unbelievable.
”I’m coming.”
”Yes, please. Fill your slave♡.”
Strong release, hot release, hot release♡.
With her pleading, I couldn’t hold back. I released deep inside her, Shiori-chan trembling as she reached her peak. Her usual “voices of strong joy!” were now muffled mmms. Her walls tightened, milking every last drop from me.
”Aah, Master’s essence is so warm… it fills me completely… I’m glad I didn’t make embarrassing noises♡.”
”It felt amazing, Shiori-chan. Great experiment. Now, let’s try another position.”
I lifted her off the desk and onto my lap, facing me.
”Master… on your lap again♡?”
”Of course. Let’s test the potion’s effect fully. Hold back your voice and cling to me.”
I entered her again. She rested her head on my shoulder, reacting softly. Her small chest pressed against me, her warmth radiating directly. If this was intimacy, then our usual encounters were passionate fusion.
”Mmm, ah, faa♡… Takumi-kun, so close… it feels so good… holding back…!”
”You’re the perfect slave, serving with embarrassment.”
”Yes, I’m Takumi-kun’s owned slave, so I’ll serve endlessly♡.”
I hugged her tightly, rocking her gently on my lap. She clung to me, reacting quietly.
”Master, I’m… peaking… peaking, peaking…♡!”
”Me too, Shiori-chan. Kiss me as you climax, slave.”
”Mmm—mmm—mmmmmmm♡♡!”
Love and strictness—both pleasures overwhelmed Shiori-chan as she sprayed love juices while kissing. I released into her again. She trembled, clinging to me as she reached consecutive peaks.
”It’s warm. I held back my voice♡.”
”You did well. I’ll praise you.”
”Yes, slave service complete♡.”
After a while, she slipped into her lab coat, wiping her intimate area—now a receptacle for my essence—with a shy smile.
”Thank you, Master… the experiment was a success. I served you without passionate noises♡.”
”By the way, Shiori-chan, do you have more of that potion?”
”Yes, it’s a prototype, but I have two more doses.”
”Can I have them?”
”Of course. Use them to thoroughly embarrass Chinatsu-chan and Haruka-chan.”
Ah, she saw right through me. Shiori-chan really is one step ahead… I accepted the doses with a wry smile, already planning my next targets.
