Dungeon And Slave: The Lustful and Violent Slave Harem of the Guard and Students Chosen as Testers for the Succubus Dungeon

Chapter 50: Rank-Up and Lust

Tester Life, Day 17, Noon, 6th Floor, Sanada Yagumo

“Hm, I’m starting to get the hang of it.”

I mutter, eating lunch in a small room while looking at a palm-sized notebook.

It contains a rough map of the areas I’ve explored so far.

From the map, I can roughly gauge the floor’s size.

The 6th floor is smaller than the cave-type floors 1 through 4. Probably because it needs more walls and small rooms than a cave floor, eating up resources so they couldn’t make it as large.

Still, it’s taking way longer to explore than the 4th floor.

It’s my third day exploring, and I’m only a bit past halfway. Might take six days to find the guardian room at this rate.

“Well, Rock being more useful than expected is a pleasant surprise.”

I thought Rock would only be a meat shield, but its evolution and new gear have made it a reliable fighter.

It tanks by drawing goblins first, holding them off while I flank. If new goblins show up, I hit them with a Fireball to thin their numbers.

Then Rock and I wipe out the initial goblins, and Rock tanks the surviving newcomers while I flank and finish them.

This teamwork has cut combat time significantly. It’s also reduced my magic usage.

Thanks to that, my mana, which used to run dry by noon even with recovery potions, still has some left. Rock’s a lifesaver.

“But dungeon monsters are weird creatures, huh.”

I tilt my head, watching Rock stand guard at the room’s entrance.

Rock drinks water but doesn’t need food. Yet it feels pain, bleeds, and gets winded from running.

It looks alive but isn’t.

Remia called it a pseudo-lifeform, and it’s really well-made.

But why the oversized balls and cock? Is there a furry-loving succubus out there?

Whatever, I finish my meal, rest my stomach, and resume exploration.

“Welcome back, Master!”

Finishing exploration and chatting briefly with Yuki and his group in the 1st floor transfer room, I open My Room’s door, and Sayaka greets me with her usual hug.

“I’m back. Did you eat the matcha cake?”

“Yes! It was delicious. Thank you, Master.”

“Glad you liked it.”

I stroke Sayaka’s head as she nuzzles my neck, then put an arm around her shoulder and enter the room.

The usual resentful shouts and cries come from the fountain area, but I ignore them.

Their jealousy and envy will probably make the Wall Butt service boom tonight.

Inside, I head to the service room, remove my gear, and hand it to Sayaka.

Catching a glimpse of her back as she puts away the gear, I get horny, pull down her shorts, channel mana into her Lust Tattoo to force arousal, and take her from behind.

Sayaka, forced into climax, sticks out her ass, squirting love juices and my semen, trembling. I carry her to the shower room.

Once she recovers from the orgasm, she washes me, and I sit on the tub’s edge, having her blow me and cum deep in her throat.

Feeling refreshed, I head to the living room, eat dinner, and go through the usual routine of gaming, drama, and porn before heading to bed.

Tonight, I decide to mess around with homemade porn, filming while fucking Sayaka missionary, saying, “I’m getting our connection on camera, it’s beautiful, Sayaka,” to embarrass her. Her shy reaction turns me on, and I cum three times in a row.

I also film her cum-covered face after a facial. Looking forward to watching it together later.

Seeing Sayaka twitch and convulse, I wonder if I should cut back, then head to the living room to settle accounts and start Wall Butt time.

Mia’s up first, so I set up the bookstand and backscratcher to let her read the manga she missed last time.

With ten minutes left, she stops reading, looking satisfied on the display, and reaches for my crotch with her tail.

I fondle her small breasts, thrust hard from behind, and cum deep inside.

Waving her tail as she vanishes, I say, “See you,” and Freyja, the usual, appears next, draining me for three loads.

I can call one more, so I do, and Lili shows up.

Her nipples are red, and her pussy’s soaking for some reason. Puzzled, I grab a marker and write “Meat Toilet,” “Masochist Succubus,” “Yagumo’s Exclusive Hole,” “Slut,” and “Pervert Who Cums from Anal” on her ass, back, and thighs, showing it on the magic crystal display.

Lili loves it, dripping more love juices and getting excited.

As I fuck her and read out the insults, her pussy tightens and she cums repeatedly.

When a succubus cums, it feels amazing for my cock. I take my time tormenting and making her cum, unloading twice inside before time runs out.

Feeling accomplished for satisfying Lili with just a marker, I think it was a great Wall Butt session, clean the dirty floor lightly, and go to sleep.

Tester Life, Day 18, Noon, 6th Floor, Sanada Yagumo

“It’s definitely increased a lot.”

Using about half my mana, I finally grasp how much it’s grown.

This morning, I woke to Sayaka’s usual blowjob.

But my urge to cum again was stronger than usual.

Since I had exploration ahead, I held back, ate breakfast as usual, and checked my mana.

My mana rank had risen to D+.

I couldn’t help but shout, “Yes!” startling Sayaka, who was gathering trash. I showed her the screen, and she celebrated with me.

Looks like the morning’s heightened lust was due to the rank-up.

I geared up, kissed Sayaka—struggling to suppress another erection—and made it to the 6th floor.

Summoning Rock, I started exploring as usual.

My body felt much lighter, and I tested my strength, speed, and dynamic vision in combat. By noon, with half my mana used, I could gauge my total mana capacity.

“Physical Enhancement 34… no, 35 uses? That’s a big jump.”

From F to F+, Physical Enhancement went from 3 to 5 uses.

From F+ to E, 5 to 10.

From E to E+, 10 to 15.

From E+ to D, 15 to 25.

Now, from D to D+, it’s 25 to 35.

That’s a huge increase compared to before.

Maybe as ranks get harder to achieve, the mana boost per rank-up grows.

Thanks to this, I don’t have to conserve magic as much.

I’ve explored over 70% of the 6th floor. I might find the guardian room today if I keep going.

But first, lunch. Maybe it’s the rank-up, but I’m getting hungry faster.

Getting stronger is great, but the worse fuel efficiency is a pain. Guess I’m burning more energy.

I’ll bring three portions of bento tomorrow.

“Alright, Rock. We’ll eat in that small room. Keep watch.”

“Wan!”

I eat lunch, but it’s not enough, so I munch on an emergency calorie bar while starting the afternoon exploration.

Four hours later, after killing six goblins, Rock crouches, emitting a black light.

“Rock’s turn now, huh?”

But isn’t this evolution too fast? It was just two days ago.

Since becoming a Kobold Defender, Rock’s shifted from finishing blows to defending and striking goblins’ openings with its short spear.

It’s killed a decent number of goblins in two days, but still… could it be getting experience from the goblins I kill too?

I think Remia said the soul fragments of monsters Rock kills are converted through me and flow into it. That lets it absorb souls, which monsters normally can’t do, by using a human as a conduit.

That would explain Rock’s growth speed.

If E-rank Rock evolved, it’s E+ now, above goblins.

The black light fades, and Rock stands.

“Whoa, you got huge.”

Rock’s now about 160 cm, even more muscular, and wider.

It’s as tall as a Kobold King, but broader—maybe 1.2 or 1.3 times wider. Beefier than me.

It might be slower than a Kobold King, but it feels heavier and stronger.

“This is all-in on durability and strength, ditching speed. Hm… with iron armor, it’d be a Kobold Knight… no, it’s the same rank as a Kobold King, so not just a knight. A General, maybe.”

Its face is a bit more dignified but still has that charming Shiba Inu vibe.

But its body’s ripped, and the leather armor looks tight.

Yeah, full iron armor would make it a General. Kobold General—sounds good.

“You’re looking reliable, Rock.”

“Waooon!”

“Haha, your bark’s deeper too. Nice. Scare those weaker goblins with a roar.”

“Waoooo!”

“Sweet. Next fight, let it rip, and if they flinch, stab ’em with the spear.”

“Wan!”

“Good boy. Alright, let’s move. Lead the way.”

Rock barks with an even deeper voice at my command, striding forward majestically with its massive frame.

I follow, eyeing its even more dependable back.

※

“I’m back.”

“Welcome back, Master!”

I didn’t find the guardian room, so I return a bit dejected, but Sayaka greets me with her usual hug.

At that moment, the guardian room vanishes from my mind. Her breasts pressing against me and the feel of her ass as I catch her make my cock ready to burst.

While exploring, tension and lack of stimulation kept my lust in check, despite feeling horny.

But hugging Sayaka makes it explode.

“Eek!”

I lift her, enter the room, and close the door.

At the entrance, I pull down her shorts, channel mana into her Lust Tattoo, and thrust into her from behind.

Hearing her moans—“Ahn, ahn, ahn, so sudden… feels good”—I pound her, unloading thick, pent-up semen deep inside.

Still not satisfied, I turn her around, fuck her standing while heading to the living room, lay her on the sofa, and cum deep inside with a mating press while kissing passionately. Then I have her ride me, slamming her ass down hard.

After three loads, I calm down a bit, but after dinner, I take her to the bedroom and fuck her again.

Including a blowjob, I cum three more times before she passes out.

Still horny but worried she’ll break, I skip settling accounts and go to Wall Butt.

I tell Freyja, the first up, I need to cum fast. She shakes her ass, dripping love juices, practically begging me. I thrust into her and unload four times.

Next, I call Aria, the bratty succubus, and without a word, fuck her for three loads without pulling out.

Watching her collapse, twitching as she vanishes, I’m stunned—13 loads and still not satisfied.

Not knowing how many it’ll take, I call another Wall Butt, and Lanaoa appears. After one load, my lust finally subsides.

Of course, Lanaoa doesn’t let it end there, and I cum two more times before time’s up.

“Phew… took 14 loads to calm down. Including this morning’s, that’s 15, but I probably recovered by night, so 14’s the number.”

Looks like D+ rank lust needs 14 loads to settle. It was 10 before, so my stamina’s jumped like my mana. Feels less human every day.

What now? Sayaka can handle five loads, including blowjobs, max. More blowjobs? No, I’d probably lose control and want to fuck her.

Blowjobs feel great, but I crave vaginal cumshots. It’s instinct—can’t help it.

Still, I can’t burden Sayaka more.

The forced climax from taking semen in her womb seems to drain her stamina a lot, especially with regular orgasms before that. Six or seven in a row would wipe anyone out.

She’s a G-rank human, even as a Slave. Her base physical ability’s different, and my D+ rank intensity might be too much.

Guess I’ll have to up my Wall Butt usage starting tomorrow.

Succubi can take anything without breaking. Sex-specialized race, indeed.

Gotta rely on Freyja and the others.

Thinking that, I settle the magic stones for about 38,000 DP.

I appraise Rock’s Magic Seal Crystal, and as expected, it’s now a Kobold General.

Its rank, as predicted, is E+, same as a Kobold King.

Gotta equip it to match the General name, so I buy a large full-body iron armor and an iron greatshield. No helmet, since human ones don’t fit a dog’s head.

The two cost about 35,000 DP, eating most of today’s earnings, but Rock’s a solid tank.

For future ranged attacks or sword-wielding goblins, a tank’s essential.

It’s an investment in my safety, so I’m happy to pay.

After buying Rock’s gear, I move it to the service room, lightly clean the living room, and head to the bedroom.

Hugging Sayaka like a body pillow, I fall asleep.
