Chapter 242 Pinwheel
Edited by: Kanaa-senpai
Tester Life: Day 105. My Room, Bedroom. Sanada Yakumo.
I woke up, as I usually did, to a familiar and intense pleasure between my legs. When I opened my eyes, I found Karen completely naked, working her mouth fervently over my member—which had recently transformed into a literal drill¹. Beside her, Leticia, also in the buff, was chirping a little song.
”Drill-c**k, drill-c**k~♪”
”Pwah… Leticia, help me out here,” Karen said, coming up for air.
”Alright, I’ll try sliding these anal beads in.”
”Hehe, Leticia-chan,” Sayaka giggled. “The Master is going to get angry with you again.”
”It’s fine. While he’s sleeping, it’s our chance—”
”…I’m awake,” I muttered, cutting her off.
Leticia froze with the anal beads in her hand and looked at me with a disappointed pout. “Ah, you’re up… what a waste.”
”Good morning, Master. Here, please,” Karen said, shifting her position.
”Yeah.”
I watched Leticia dejectedly set the beads aside while I began to suck on the breast Sayaka offered me. Leticia soon joined the fray, helping with the oral service. She rolled my balls in her hand while running her tongue along the spiral grooves of the shaft. My sensitivity had skyrocketed since the mutation, and under the combined assault of Karen and Leticia, I hit my limit almost instantly.
Splotch! Splurt! Splutter!
”Ngh—?!”
Karen let out a small muffled sound of surprise at the sudden, massive volume of the release, but she dutifully swallowed every drop. Once I finished, Leticia reached out and slowly milked the shaft from the base to ensure nothing was wasted. As soon as she finished, Karen pulled her mouth away and immediately kissed Leticia, passing the collected fluids into her mouth.
”Mmph… does it taste better than before?”
”Yeah, it’s like I want to drink more? It isn’t sweet, but it’s strange,” the two of them whispered, exchanging impressions.
Ever since I developed the drill-c**k, everyone had started saying my seed tasted better. It seemed my fluids had undergone another mutation. During my time off yesterday, I hadn’t invited any guild members to the isolated island, so I had spent the day ravishing the girls all over the place to verify the drill’s performance.
The results were as follows: a reduction in food requirements from four servings to three; permanent quick-draw mode; the ability to instantly replenish fluids using Mana Capacity; the capacity to transfer Mana to the girls via internal e**culation; and finally, an aphrodisiac effect. I’d figured out the first four early on, but I only noticed the fifth one around noon. I realized the stuff acted like a drug because Sayaka had started begging for more even after the heat from her crotch tattoo had subsided.
Karen and Sheena are already perverts, and Leticia isn’t much better. Sanae is passive, but her eyes plead for more with everything she has. Moe and Kyoko have such a massive rank difference between us that it’s only natural they’d go into heat just from being near my Mana, but Sayaka is C-rank and a modest woman. Aside from when I first bought her as a low-rank slave, she never asked for it herself. Usually, as her rank increased, she became more reserved, focusing only on my pleasure when I requested it.
Yet, there she was, out of breath and begging for more. Everyone mentioned that just the scent was enough to get them excited. Even Lunaria, who was C+ rank, seemed to stay in a constant state of arousal. It was clear my seed now contained an aphrodisiac component, and the effect doubled when I finished inside them.
(Tch. If this were a body odor thing, I could walk around on the surface and get laid without even trying. But I can’t exactly use jizz as cologne. I’d just be ‘the guy who smells like a locker room.’ Most women would run away before the effect even kicked in. Totally useless.)
Well, I’m happy Sayaka is becoming more of a nympho, and the others had been going through a bit of a dry spell in terms of their desire since their ranks rose anyway.
”Hey, Darling. I want you to put it in,” Karen said, her eyes turning glassy.
”Mm, me too,” Leticia added.
The two of them, having finished their ‘cleanup’ oral, were looking at me with dazed expressions.
”Fine, fine. Just one round,” I sighed.
”Yay! Me first!”
”No fair, I want the drill too!”
The two of them began to scramble over each other to straddle me. I just shared a wry smile with Sayaka as we watched them. I suppose if I think of the aphrodisiac effect as an ability to make my slaves even more lecherous, it’s not so bad.
* * *
”Alright, starting today, we’re scouting the Northeast perimeter.”
After a short post-breakfast break, we geared up and arrived at the 14th Stratum. I stepped out of the teleportation circle and informed everyone we’d be tackling the final section of the outer rim.
”Let’s rack up some coins and hit the Gacha today!” Karen cheered.
”Ohh~!” Leticia joined in.
”I’m not rolling anymore,” Sanae muttered.
”I’ve already reunited with the Princess,” Sheena added. “I need to bank my luck for a while before I feel confident again.”
”Fufu, that was certainly a bigger jackpot than any gold capsule,” Sayaka teased.
I gave them a wry smile, told Hanako and Saizou to get a move on, and headed toward the northeast.
(Wait. Did I just see Karen and Leticia give Saizou a knowing nod? Was I seeing things?)
While I was wondering about that, Saizou vanished from sight. I tilted my head in confusion but kept walking behind Hanako.
* * *
”Hup!”
I dodged the swing of an approaching Orc by twisting my body, slashing through its leather armor and flank with my Black Steel Machete as we crossed paths.
Bugeeeh!
The Orc collapsed to its knees. Faster than I could move, Sheena—who had already finished her own target—flew in. Her Black Steel Rapier flashed like a swallow’s return, slashing the Orc’s neck twice and sending its head flying.
”Wow! A lightning flash!”
”Sheena the Headhunter!” Karen and Leticia shouted.
Sheena dropped to one knee, looking like she’d taken psychological damage.
”Knock off the ‘friendly fire’ nicknames,” I told the girls. “If you ruin Sheena’s combat style with embarrassment, we’re in trouble.”
”But it’s so cool!”
”Yeah, totally badass!”
”It’s fine, Master,” Sheena sighed. “I’ll just make the Princess take responsibility for this later. I used to love cool titles, but… some things are better left unknown.”
(She just learned what ‘Chuunibyou’² means, and it’s killing her.)
Just as I was thinking that, my detection magic picked up five Orcs approaching from a nearby alley. “Heads up, we’ve got adds from the front.”
”Yakumo! They’re coming from the back left and right alleys too! Two more groups!”
”Tch, did we push too deep into the interior?”
”Darling! Hanako, Lucy, Leticia, and I will handle this!”
”Nfu… finally, the time has come,” Leticia whispered.
”? Fine, I’ll leave it to you. Rock, keep an eye on those two! Sheena, with me!”
I ignored Leticia’s cryptic comment and ran toward the rear with Sheena. Ten Orcs burst from the side alleys simultaneously.
Ice Arrow!
Sayaka’s spell hit the ground right in front of the lead Orcs. The floor turned to a sheet of ice, and the first four Orcs tripped, causing a massive pile-up that blocked the alleyway. Orcs have high kinetic vision and can often parry arrows, but they can’t parry a slippery floor.
”Sheena, let’s melt them! Fireball!”
Our spells slammed into the huddled mass. My double-mana Fireball turned the alley into a furnace. Behind the flames, I saw an Orc archer falling from a roof—Sanae had finished her work. Sheena and I moved in to finish off the survivors.
”Well, that’s that,” I muttered, cleaning my blade. I turned back to check on the others.
”Oh noooo! I missed! I have to reload! This is so dangerous!” Karen’s voice was the flattest, most wooden piece of acting I’d ever heard.
”Ugh… owie… my tummy hurts all of a sudden…” Leticia groaned, doubling over with all the grace of a middle-schooler faking a fever.
What the hell? Four Orcs were already dead. One lone survivor was charging at Hanako. Leticia was ‘collapsed’ on the ground while Feli barked ‘worriedly’ beside her. Karen fired her magic gun, but ‘accidentally’ only hit the Orc’s sword, disarming him but leaving him healthy enough to keep charging. Lucy was just standing there with a knife, barking at the sky. Even Sayaka was just standing there with her hand over her face.
”What are they doing?”
”I… have no idea,” Sheena replied, baffled.
The Orc raised a fist to punch Karen. She didn’t reload or cast a shield; she just stood there like a damsel in a play.
”Dammit, stop playing around!” I leveled my hand to fire—
Whiz!
Thwack!
Something flew through the air and nailed the Orc’s arm.
”Wait… is that a pinwheel?”
I blinked. A steel barbecue skewer was buried in the Orc’s bicep. On the end of the skewer was a colorful, spinning pinwheel³.
”Yashichi!” Karen screamed with joy.
”I knew you’d come for us!” Leticia cried.
They both looked up at the roof. There stood Saizou, arms crossed, looking stoic with a pinwheel clamped between his teeth.
(You… you’re going with the ‘Shadow Ninja’ gimmick from that period drama?!)
”So this was the plan,” I muttered, feeling the exhaustion hit.
”It would appear so,” Sheena sighed.
We both realized they were reenacting a scene from the old period drama we’d watched. Saizou was playing the role of the mysterious ninja who throws pinwheels. I remembered Karen whispering to him on the beach—she must have spent the whole break coaching him.
”Darling! Wasn’t Saizou-Yashichi so cool?!”
”He practiced so hard to hit the arm with the pinwheel,” Leticia added.
”Listen to me,” I said, trying to be stern. “Don’t play games during a fight. If you do this in the inner floors, you’re going to get someone killed. Understand?”
”We wouldn’t do it there~!”
”Inner floors are too scary for games.”
”Fine. As long as you get it. Let’s move.”
I made a mental note: if they do this again, I’m cutting their snack allowance. That’s the only language they speak.
We kept moving, but for the rest of the day, every time an Orc showed up, a pinwheel would come whistling out of the shadows. Apparently, Saizou really liked his new job.
(Saizou… is this really the life you want?)

Summary:
Yakumo discovers his new ‘drill’ mutation has mutated his seed into a potent aphrodisiac, causing his companions to become more aggressive. During a dungeon crawl in the 14th Stratum, Karen and Leticia stage a ridiculous roleplay to let Saizou act out a ninja fantasy from a period drama. Despite the absurdity, the team successfully clears the outer perimeter.
—
Trivia:
- Yakumo’s seed now transfers Mana directly, allowing him to ‘battery’ his companions.
- Sayaka’s personality shift is chemically induced by Yakumo’s new biology.
- The ‘Windmill/Pinwheel’ is a reference to Yashichi from the drama Mito Komon.
- Sanae’s refusal to roll Gacha stems from a streak of ‘white capsule’ (common) trash.
- Orcs in this world have high kinetic vision, making ground-freezing a superior tactic to direct projectiles
—
Character Insight:
Saizou, usually a silent background figure, shows a desire for individual identity and flair by committing to the ‘Yashichi’ roleplay, even practicing his aim with barbecue skewers.

Lore And Worldbuilding Context:
The author uses ‘Mito Komon’ tropes to contrast the dark ‘Dungeon & Slave’ setting with lighthearted, nostalgic Japanese comedy.
