Chapter 40 Underwear and Floor Plans
Edited by: Kanaa-senpai
Sayaka’s face was flushed a deep crimson as she straddled me.
Beyond her neatly groomed, thin bush, my warmth brushed against her opening. Slowly, she began to sink down, welcoming me deep into her core.
”Nngh… it’s amazing… ah, I can feel the rhythm… nhaahhh!”
As I settled deep, she gave a sharp, involuntary shudder, but she didn’t stop there. She continued to welcome my presence fully.
”Ah… it’s all the way in… ngh.”
Once I was buried to the base, she reported her success to me with heavy, glazed-over eyes. As always, her warmth was incredibly close, tightening around me with every breath.
”Good girl. Now, move for me.”
”Yes… ngh… ah…”
At my command, Sayaka began to rock her hips back and forth. The tentative movement gradually shifted into a deep, grinding warmth.
”That’s it, Sayaka. It feels incredible. How about you? Does it feel good?”
”Ah… ah! It feels… so good!”
”Heh, I bet. Next, I want you to move faster. Can you do that?”
Hearing her repeat those words only pushed me further. I wanted to feel her closeness.
”Nngh… ah… yes, Master…”
Sayaka gave her reply and stopped her grinding. Bracing both hands against my stomach, she pushed up onto her knees, taking a wide-stanced riding position. Then, after slowly lifting her hips, she brought them down with a burst of momentum.
She repeated the motion in a frantic, rhythmic heat.
”Ah… ah… fuuh… ah!”
I watched her warmth swaying right in front of my face, while just beyond, my presence disappeared and reappeared in the depths of her core. Seeing her like this for the first time in a while sent a fresh surge of warmth.
”Yeah, that’s it. You’re a natural, even though it’s your first time. Did you practice this too?”
”Ngh… nhaah… y-yes… I practiced… ah, it feels so good… I did it for you!”
The rhythmic warmth echoed as she moved over and over, her closeness stroking my warmth with every downward motion. I reached out with both hands, tending to her swaying warmth roughly.
”Ah! My warmth… it feels so good… ah, wait-when you touch me like that… aahhh!”
As I tended her warmth, Sayaka’s closeness seized even tighter. She was gifted. Some girls just don’t have the knack for rhythm, but she was a natural-born talent.
I started moving back, meeting her halfway to drive the pleasure home. As she continued to move without rest, I realized I was reaching my limit.
”Good girl, Sayaka. I’m about to crest.”
”Ah… yes! Let it out… ah, ah… please… fill me… ngh… I want Master’s warmth… give it to me!”
”Then give me everything you’ve got for the finish. Move faster!”
I pulled her down into a deep kiss, our warmth entwining as she accelerated. Hovering over me, she skillfully moved only her hips, her warmth becoming a blur as she moved in a high-speed, frantic finish.
”Guh-I’m peaking!”
My warmth surged out in hot, heavy pulses.
At the signal of my release, Sayaka froze, her hips pinned down so she took me to the very hilt. Thanks to that, I was able to release deep inside her, my warmth flooding into her core.
”Mnnngh! Ah… ahhhhhhhhh!”
The sensation of my warmth hitting her core triggered a massive, forced climax. She broke the kiss, collapsing onto my chest as her body racked with involuntary tremors. Her closeness convulsed, squeezing my warmth from the base and holding every last drop deep inside.
”Hah… hah… hah… Master… did… did it feel good?”
Once the afterglow of her climax had settled, Sayaka sat up and asked me with a flushed, beaming face.
”Yeah. It was the best. We’ll do it again later.”
”Ah… yes!”
She gave me a happy, radiant smile at my reply and lifted her hips, sliding off my warmth. As she did, a gentle warmth lingered. She moved down to hover over me.
”I’ll clean you up.”
With that, she carefully and meticulously tended to me.
Needless to say, I warmed again immediately. But it was our day off, and I didn’t want to exhaust her this early in the morning. I forced myself to show some restraint.

Afterward, the two of us headed to the bathroom to shower. Sayaka was absolutely thrilled with the women’s shampoo and conditioner I’d bought the night before.
Apparently, back at the Training Facilityⁿ, it was mostly just bathing in a lake. They only got to use a real bath about once every three days-and even then, it was a timed group event with a crowd of people. Sounded more like the military than a school.
I mentioned how surprised I was, since her hair was so glossy and her skin was so fresh when she first appeared. She explained that once the purchase was finalized, she was separated from the others and several Succubus staff members spent an hour “polishing” her entire body in the bathhouse.
I see. That explained why I’d been made to wait for an hour before she was delivered.
Once we finished our shower, I handed her the underwear in the bedroom. She was shy about it, but clearly happy. When I had her put it on right there, the “Magic” kicked in-the fabric automatically adjusted until the bra and panties were a perfect fit.
”It looks great on you,” I said simply.
”Th-thank you! These are amazing. I thought they looked a little small at first, but once I put them on, they fit like a second skin.”
”It’s an auto-sizing enchantment. Just dungeon logic-don’t think too hard about it.”
”Right, magic… I forgot. Everyone back at the facility was talking about how you blasted those bipedal dogs with fire.”
”Wait-they can see my fights on a video feed?” I asked, a bit concerned. “Does it show the inside of the rooms too?”
I felt a sudden jolt of anxiety. I was well aware I’d been doing some pretty perverted things in the Wall-Buttⁿ sections. Using clothespins on the masochistic white Succubus Lilith’s nipples, anal play with kokeshi dolls, belt-whipping… I’d even done some shame-play with the middle-schooler Remia and the Noble Succubusⁿ Freya, making them urinate. I wondered if Sayaka and the other students were completely repulsed by me.
”No, it was only inside the caves,” she replied.
”I-I see. Good.”
I let out a massive sigh of relief. It seemed they hadn’t been watching the private rooms.
I handed her some loungewear and sleepwear, which she accepted happily. She changed into a pair of black shorts and a sleeveless white blouse before we moved into the living room.
For the record, this room is a 1SLDKⁿ-a living area of about 16 tatami, an 8-tatami bedroom, and a service room (basically a storage unit) about 4 tatami mats large. I planned to use that for loot and equipment.
As for the layout, the entrance has a large shoe closet. Right off the hallway, there’s a sliding door that houses a prototype Magic Stone Generatorⁿ. The service room, toilet, bathroom, and bedroom are all lined up along the corridor.
The toilet is, of course, a Western-style throne with a bidet seat. Sayaka was ecstatic about it. Apparently, the Training Facility only had pit latrines.
The bathroom has a separate dressing area and vanity. There was even a designated spot for a washing machine next to it. I remembered how I used to wash my clothes by hand in the old shower room and realized how much easier laundry was about to become.
The bathroom itself is fairly spacious, equipped with a mist shower and enough room for three people to wash up at once. The bathtub is also huge-it could easily fit three people for a soak.
The bedroom features a king-size bed and a walk-in closet in the back. Even though it’s a “single person” unit, it’s not exactly cramped.
From the hallway, a sliding door leads into the living room, with a counter kitchen immediately to the left. For a bachelor pad, the kitchen is massive, boasting a four-burner IH induction stove. The water pressure is perfect, but since the Shopⁿ didn’t sell actual groceries, I’ll likely only use it to boil water for tea.
I’d probably stop using the stove entirely once I bought an electric kettle. I wondered if they’d eventually start selling food ingredients from a Magic Stoneⁿ powered vendor.
I’d checked everything before bed last night, but it was then that I suddenly realized the layout and facilities felt incredibly familiar.
The calm, dark brown hardwood floors. The recessed, stylish indirect lighting in the large living room. The sleek black-and-white monochromatic bathroom with its high-tech mist shower.
I recognized this design.
It was a mirror image of the new condominiums they’d built right across from the Academy.
On a bored day off at the end of summer, I’d gone to an open house because my staff dormitory felt too small. This was the exact “Bachelor Executive” unit the realtor had recommended.
I never ended up buying it, but it seems that building was swallowed by the dungeon too. It was finished but hadn’t opened for move-ins yet, so hopefully, no one was actually inside when it happened.
Regardless, I’m personally satisfied. The place is spacious, has plenty of storage, and the latest tech.
Now, I just have to see how the electricity that supports all this holds up. I can only hope it doesn’t interfere with our daily life.

Summary:
Following a morning of intense sexual activity where Sayaka demonstrates her practiced techniques, the Master and his slave move into their new 1SLDK apartment within the dungeon. The protagonist discovers the apartment is a perfect replica of a real-world condominium he once toured. They enjoy modern amenities like bidets and mist showers, a stark contrast to the primitive conditions of the Training Facility.

Character Insight:
Sayaka shows significant growth in her sexual confidence, expressing a deep desire to be ‘bred’ and ‘filled’ by the Master, which marks her transition from a mere student to a devoted personal slave. The Master reveals a pragmatic and slightly paranoid side, worrying about the visibility of his previous perversions on the dungeon’s monitor system.

Behind the Scene:
The author uses the 1SLDK layout to bridge the fantasy dungeon setting with modern Japanese urban life, a common trope in isekai and dungeon-crawler genres that appeals to the reader’s sense of ‘modern comfort in a magical world.’
