Chapter 105 Morning Humping and System Calibration
Edited by: Kanaa-senpai
The forty-second day of my life as a Tester¹ began in the hazy light of a holiday morning. I stirred awake in my bedroom to a sensation of searing heat and slick friction centered entirely on my crotch. Opening my eyes, I found Sayaka and Sheena locked in a coordinated double-breastjob.
To the side, Karen was frantically practicing, her hands heaping her own massive breasts together in an “air-paizuri” rhythm. Meanwhile, in the far corner of the bed, Sanae cowered, clutching the sheets to her chest, her face a mask of crimson as she watched the display in mortified silence.
My thing was already wet from their spit and my own stuff coming out. Sayaka has firm E-cups and Sheena has soft big F-cups. They work together, squeezing me hard. When they see I’m awake, they smile at each other. Then they lick the top of my thing fast with their tongues. Their breasts keep moving up and down. It feel so strong, my hips jump up from the bed.
”Ahhn… Master going to come already?” Sayaka ask.
”Yeah… close… ngh, coming now!” I say loud.
Then a big hot stuff come out from me.
”Ah… mmm…” Sayaka say quiet.
”Sayaka, give me some too,” Sheena say.
When I finish, Sayaka put her mouth on me quick to take the first part. Sheena take turn right after, like they do it many times, take the rest. Karen and Sanae watch everything, their face red.
Sheena stop with wet pop sound, give one more kiss on the tip. Both girls open mouth wide, show the white stuff on tongue, then swallow together. They make sure I see all gone, then smile happy.
”This your morning service,²” Sheena say calm. “Every morning do this. No skip. Holiday maybe use vagina instead mouth. I decide who when. You do it with all heart.”
”I got it! I try hard!” Karen say happy. She nod fast, her G-cups shake a lot.
”I… I not do it! No!” Sanae say.
”Still no?” Sheena voice cold. “You not understand you our vessel³ yet.”
”I not vessel! I… ngh! I not do this service!” Sanae shout.
I look at her. She try act strong after last night. Others sleep before her full give in, so she think can pretend. But Sheena angry more. I need stop or bad. I want show her soft side slow, but now must order.
”Sanae. Order,” I say. “Get on top, ride me.”
”What!? Here now!?” Her body shake. “Ugh… legs… I can’t stop…”
She look so shame, drop sheet. Crawl over me. Her place already wet, guide my thing in, go down slow. Everyone watching make her more excited I think.
”Ngh… Aaaahhh!” Sanae cry.
”Move hips now,” I tell her.
”Yes… nnh… hah… feel… feel good…”
”More. Say what you think real.”
”Nnh! Aaaah! No… too shame… hah… I like it… I like Yakumo… I like Yakumo thing! Want inside always! Never know sex feel so good! Aahh, all look… so bad… but feel so good good!” Sanae cry loud.
She change total. Sayaka, Sheena, Karen quiet, shock. Me too surprise. Crotch Crest of Subjugation⁴ control body only, but when inside, her mind go away. I not use much power even. She special.
”You slow now,” I say. “Go faster. Make me good.”
”Yes… huff… yes! Nnh… ah!” Face all red, Sanae put hands on my chest like spider-cowgirl. Hips go up down fast. Every time wet sound loud, stuff go on my legs. Her move not good – like new person, clumsy. Sayaka much better. Karen say Sanae skip sex class before, yes show.
If like this, take all morning. I have time limit. I change system: Premature Ejaculation Mode: Strong.⁵ My thing feel everything ten time more.
”Sanae, come down. Kiss,” I say.
”Yes…” she whisper.
She fall on me, kiss hard, tongue in my mouth fast. I hold her ass tight, keep her there, push up strong. She make sound in mouth. I finish quick, hips stop, shoot deep inside her.
”Nnnh! Fuuuu-aaaaaah!” Sanae scream.
When my stuff fill her, big feeling hit her hard. She stop kiss, breathe heavy, face in my shoulder. Body shake shake. I let last bits go inside her tight place, feel pulse.
Once the waves subsided, I rolled her off and turned to the wide-eyed Sayaka and Sheena.
”Phew… So, that’s the deal,” I said. “I talked things out with Sanae last night and cleared up our ‘misunderstandings.’ She realized how much she owes us—especially after we saved her. Eventually, all that skin-ship turned into genuine feelings.”
It was a blatant lie, but I had to give them a narrative reason for her sudden devotion without revealing the ‘Creampie Favorability Boost’ mechanic.
”I see,” Sayaka murmured. “I was shocked to see the Ice Queen acting like a lovesick puppy, but if it’s for Master, it makes perfect sense.”
”She was an insolent brat,” Sheena added with a smirk. “But if she’s finally recognized my Husband’s greatness, I suppose she’s not a complete fool. Fufu.”
”Yeah… something like that,” I replied.
”Are you kidding me? To be real, that’s about as scientific as some drunk old geezer in the sticks rambling, ‘Just give a girl a good lay and she’ll be putty in your hands.’ It’s basically an urban legend.
I thought they’d at least be a little suspicious, but I can’t believe they bought it that easily… Sayaka and Sheena’s opinion of me is so high it’s actually terrifying.
’I’m still the one who loves Master more, though,’ Sayaka said with a beaming smile.
’I shall acknowledge Sanae if it is as a s*x slave,’ Sheena added.
All I could do was stand there with a twitching expression as the two of them went back and forth.
* * *
I stepped out of the shower, grabbed a soda from the fridge, and cracked the cap as I sat down at the desk where the Magic Crystal⁶ waited.
Sayaka and the others were still in the bathroom.
Having five people in the washroom was a bit of a squeeze, so by Sheena’s decree, Sanae and Karen were relegated to the tub to ‘observe’ while Sayaka and Sheena scrubbed me down.
Even for me, having an audience while I brushed my teeth was embarrassing. But it’s hard to complain when Sayaka is looking at you with that pure, joyful smile while she brushes away. The electric toothbrush I’d bought to prove I could do it myself had mysteriously vanished, too.
Now that I think about it, my electric razor went missing as well. Well, it’s not like there are any other suspects besides Sayaka and Sheena.
The two of them had already informed Karen and Sanae that brushing my teeth and shaving my face were their jobs, so the new girls didn’t need to bother.
Karen just gave a strained laugh, though Sanae looked pretty salty about it. Personally, I wanted to tell Sayaka she didn’t need to do it either, but I knew she’d make that heartbreakingly sad face, so I kept my mouth shut.
Oh, right-to keep some semblance of order in the harem, I’d officially ordered Sanae and Karen to obey whatever Sayaka and Sheena told them.
Moving forward, Sayaka, as the Head Slave, would handle the administration of any new girls I bought, while Sheena would take charge of their ‘education.’
I didn’t plan on establishing a strict hierarchy for anyone else. My goal was to treat Sayaka and the other girls as equals. That said, if you asked me who my favorite was, it would obviously be Sayaka-the very first girl I bought, who’s been devotedly supporting me since day one.
Lost in thought, I booted up the Magic Crystal.
A few new icons had been added to the home screen: ‘Weapons & Armor Exchange’ and ‘Party.’
The main menu now read: [Shop] [Magic Stone & Item Buyback] [Appraisal] [Weapons & Armor Exchange] [Party].
Tapping ‘Party’ brought up three sub-menus: [Register Party], [Transfer DP⁷], and [Party Comms]. It looked like a party could hold up to six people, allowing for DP sharing and long-distance communication.
When I messed around with the registration, a list of all the testers popped up.
I wondered for a second how the system knew everyone’s names, then realized it was probably the same way it knew the slaves’ names. I just rolled with it.
It looked like I could just pick someone from the list to form a group.
Well, that system has nothing to do with me.
Next, I opened the [Shop] and hit [Facility Expansion]. Sure enough, alongside the shower and kitchen options, [Party Room] had been added.
Selecting it showed five ranks of rooms:
* Rank 1:* 50,000 DP (120 sq ft)
* Rank 2:* 100,000 DP (Two rooms: 160 sq ft + 80 sq ft)
* Rank 3:* 150,000 DP (Three rooms: 240 sq ft + two 80 sq ft rooms)
* Rank 4:* 200,000 DP (Five rooms: 240 sq ft + four 80 sq ft rooms)
* Rank 5:* 300,000 DP (Seven rooms: 300 sq ft + six 100 sq ft rooms)
Redoing ‘My Room’ into a one-bedroom apartment cost 100,000 DP, so Rank 1 looked like a bargain at first-until I realized these rooms had no toilet, kitchen, or bath. They were literally just empty boxes. I’d have to pay extra to install the plumbing.
Still, if you think of it as a dedicated ‘fuck-room’ for the whole party to share, maybe it’s worth the price.
According to the description, buying one would manifest a private door in the ‘My Room’ of every party member. Only the room owner and their slaves could use it, so there was no risk of other members wandering into my private space.
Again, not a system I really need. Maybe I’ll tell Yuki’s group about it once they clear the 5th Floor.
As for the [Weapons & Armor Exchange], it’s a marketplace where you can list gear you’ve placed on the pedestal for a set price. No auction house features yet. If something sells, the DP is automatically deposited into your balance.
Predictably, the listings were empty. I didn’t have anything to sell either, so this probably won’t be useful until more people break through the 5th Floor. It feels like a way for high-level players on the 10th Floor and above to gear up the newbies. Still, it’ll be a nice way to offload duplicate loot or hand-me-down gear later on.
And then, the main event: [Unlocked Ingredients].
I opened the [Food] section of the Shop.
Row after row of rice, meat, and vegetables appeared. Even seasonings.
”Oh… it’s actually Earth food,” I muttered.
Honestly, I was worried I’d be stuck with fantasy ingredients. Even if Sheena could identify them, I’d much rather eat what I’m used to.
If Sheena fed me some ‘delicious’ meat that turned out to be a giant swamp rat, I’d lose my appetite for a week.
”Ah, of course… there are purchase limits,” I said to myself.
Scanning the list, items like rice, wheat, meat, and fish were capped.
Here’s the breakdown of the daily limits and prices:
[Limited Items]
* Rice:* Up to 2kg — 400 DP
* Wheat:* Up to 1kg — 100 DP
* Beef:* Up to 1kg — 500 to 2,000 DP
* Pork:* Up to 1kg — 300 to 1,000 DP
* Chicken:* Up to 1kg — 200 to 500 DP
* Fish:* Up to 5 packs — 200 to 500 DP
[Unlimited Items]
* Vegetables:* 100+ DP
* Fruits:* 100+ DP
* Processed Foods:* 50+ DP
* Seasonings:* 50+ DP
The prices are pretty steep across the board, but it’s still way cheaper than buying the pre-made meal sets.
The price range for meat seems to depend on the cut and the grade.
As for the staples, the wheat limit is about four loaves of bread, and the rice is about thirty bowls’ worth per day. At this rate, I’ll probably polish off a third of that myself. My appetite has been insane ever since I had to start eating for four people. Well, if I load up on meat, maybe the rice consumption will stabilize.
The processed food section had everything from canned meats and fish to natto⁸ and tofu. No instant rice or hardtack, though.
And the processed stuff is a total ripoff. 500 DP for five packs of natto? That’s five times what you’d pay at a supermarket.
Whatever. I’ll buy one of every canned good to start a stockpile. I’ll buy the max rice, wheat, and fish every day too. I’ll cram as much meat as possible into the freezer. Just like the fish, if I keep it frozen, it’ll last six months.
”Yeah, I’m gonna need a dedicated storage fridge and a deep-freezer,” I decided.
My own appetite is one thing, but if the harem keeps growing, we’re going to hit a food shortage eventually. Better to start hoarding now while I can.
I’ll add those to the shopping list, along with hair dryers for Karen and the others, once I remodel the room.
For now, I’ll skip the cooking and just grab a standard breakfast set.
I also picked up a jar of pickled carrot sticks. I can’t wait to see Sheena’s reaction to those.
Finally, I checked the beverage tab to see if I could get some tea, and then—
”Wait… Oh! Ohhh! Beer! They have beer!” I shouted, nearly knocking my desk over.
The second I saw the beer listing, I practically lunged at the screen.
Obviously, they don’t sell booze at the academy. That means they must have replicated it from the staff dorms. Was it because I asked Lanora for a favor back at the Wall-Butt⁹? Or was this a special reward for clearing the 10th Floor?
I don’t care what the reason is—my nightly routine just got a whole lot better. At 50 DP a bottle, it’s a bit pricey, but that goes for all the food. I’m just grateful it’s even an option. Thank you, Lanora. Next time we’re at the Wall-Butt, I’m going to make sure I rock your world.
I immediately bought a few and shoved them in the fridge.
You can’t pick the brand, so it’s a bit of a gamble what you get each time, but that just adds to the fun.
Alright, the girls should be out any minute now.
Once we eat, it’s time to remodel the room and claim that ‘Isolated Island.’ Oh, and I need to check out the Magic Tent.
After that, I’ve got furniture, bedding, appliances, and even underwear to buy.
It’s going to be one hell of a busy day off.

Summary:
Yakumo wakes up to a morning ‘service’ from Sayaka and Sheena while Karen practices and Sanae watches in shame. To break Sanae’s feigned resistance, Yakumo orders her to ride him, leading to a public display of her complete psychological and physical submission. Yakumo uses a system ‘cheat mode’ to finish quickly and then lies to the others about Sanae’s change of heart to hide the underlying favorability mechanics.
After successfully convincing his slaves of a questionable ‘urban legend,’ the protagonist explores new system features unlocked after clearing the 10th floor. He examines the ‘Party Room’ expansion and a marketplace for gear. The highlight is the unlocking of real-world food and alcoholic beverages, prompting him to plan a massive hoarding operation and room renovation.
—
Trivia:
- Yakumo is specifically on day 42 of the ‘Tester’ period.
- Sanae was known as the ‘Ice Queen’ and had a reputation for being serious/unskilled in s*x.
- Sheena acts as the manager/enforcer of the harem’s morning schedule.
- Yakumo has a hidden ‘Creampie Favorability Boost’ mechanic he is intentionally concealing from the girls.
- Sayaka and Sheena are actively asserting their ‘senior’ status over the new girls, Karen and Sanae.
- The protagonist’s physical appetite has increased significantly, requiring him to eat for four people.
- The ‘Party Room’ allows for interconnected private spaces that maintain individual privacy.
- The beer available in the shop is likely a result of the protagonist’s previous interaction with Lanora.
- The protagonist has a ‘Head Slave’ system in place to delegate management and education
—
Character Insight:
Sanae shows a massive gap between her outward ‘serious’ personality and her extreme vulnerability during s*xual acts, suggesting the Crest’s effects are deep. Yakumo demonstrates a manipulative tactical side, managing his harem’s internal relationships with lies to maintain control over his system secrets.
The protagonist shows a mix of strategic planning and hedonistic desire. While he claims to want equality in his harem, he admits to favoring Sayaka. His reaction to the beer highlights how much he misses Earth’s comforts despite his success in this world.
—
Behind the Scenes:
The ‘Spider-cowgirl’ position is a specific visual trope in adult media where the woman braces herself forward on all fours/hands while straddling.
The author uses this chapter to ground the ‘game mechanics’ of the world, transitioning from combat/dungeon crawling to ‘base building’ and resource management typical of the genre.
