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

Chapter 89: Rank-Up and New Ability

Tester Life – Day 36 – Rest Day Morning – My Room – Yagumo Sanada

I wake to find myself in a basement, naked, arms bound with rope, dangling from the ceiling.

The walls are lined with various restraints and what look like torture devices.

At first, I think Mia’s kidnapped and locked me up again, but she wouldn’t set up a room like this, so I reconsider.

Who, then? As I ponder, someone enters.

It’s her—the wicked masochist succubus I tamed last night.

She’s shouting something about “how dare a noble like me be treated so cruelly,” but her words lack conviction.

Instead, she keeps stealing glances at my cock, fidgeting her thighs, cheeks flushed, as if expecting something.

Her words are haughty and resentful, but her expression and actions don’t match.

I look at the rope binding my wrists.

It’s cheap, store-bought stuff.

Glancing at the wall’s tools, I spot a sturdy chain restraint. No question, it’s tougher.

Got it. I fire a spell at the rope.

“Wind Cutter!”

The rope snaps easily. As expected, the wicked masochist succubus looks at me with a mix of shock and anticipation. I activate Physical Enhancement and pounce.

Her resistance is half-hearted.

I quickly overpower her, binding her hands with the chain restraint, threading it through the ceiling to hoist her up.

I yank down her bondage outfit from chest to feet in one go, clipping clothespins to her nipples for some reason.

She screams “Hiii!” but I ignore it, move behind her, grip her plump butt, and thrust inside.

Spanking her and tugging the clothespins, I whisper, “This is what you wanted, right? You’re one hell of a masochist,” and her body convulses in climax.

Even mid-orgasm, I roughly grab her hair, pulling as I thrust, careful to avoid her double-tongue pussy’s grip on my glans.

Feeling close, I slam into her cervix, letting her double tongues tease my glans while yanking the clothespin strings hard.

She shrieks, climaxing again. Unable to resist her wild tongues, I ejaculate—

And wake up.

Pleasure surges through me. Opening my eyes, I see Sheena, facing away, her butt twitching as she trembles.

Oh, it’s a rest day, so she woke me with morning sex instead of a blowjob.

Glancing beside me, Sayaka rolls onto her side, offering her breast, so I latch on.

Must’ve been last night’s rough play with the wicked masochist succubus that gave me that weird dream.

Lili, second in line, looked guilty—she probably knew that succubus was coming.

As punishment, I treated her the same way, and she squirted, ahegao’d, and passed out like the succubus.

Freyja, third, gave a wry smile.

Maybe, as upper-class peers, she knows the wicked masochist succubus. I told her I’d disciplined her and established dominance, so no worries.

Freyja’s pussy was, as always, the best. The wicked masochist succubus was great, but Freyja’s noble elegance is unmatched.

A lowlife like me gets more satisfaction defiling refined, classy women.

Recalling last night, Sheena, recovered from her climax, slowly moves her hips to milk the last of my semen.

Hm?

I feel a strange arousal from just that.

Focusing on my cock, I sense Sheena’s exquisite pussy—natural, bumpy folds stimulating me from all angles.

Concentrating further, I feel each bump’s texture, and somehow, the pleasure is several times stronger.

It makes me hard again, and it feels so good I could cum any second.

What the hell?! Too fast! What’s this sensation…?

Confused by the semen rising rapidly and my overly sensitive cock, it’s like when I was a kid, first peeling back my foreskin, my glans exposed to air… Oh, no, this is bad!

“Sheena, w-wait, stop—guh!”

“!? Nn, ah, aaaa!”

I try to tell Sheena to stop, but my hypersensitive cock can’t hold back and bursts.

No way… I came a second time just from her post-ejaculation milking.

Sheena, unprepared for such a quick second shot, is forced into another climax as my semen hits her womb, her back arching, body trembling.

I’m lost, thrusting upward, surrendering to the overwhelming pleasure.

“Kh… haa haa haa.”

“Goshujinsama?”

Lowering my raised hips and catching my breath, Sayaka cautiously speaks, looking confused.

“Sayaka, let Sheena rest and give me a blowjob.”

“Uh, yes.”

Despite her confusion, Sayaka follows orders, moving the exhausted Sheena, limp from consecutive forced climaxes, off me and laying her beside me.

Without hesitation, she takes my cock, coated in Sheena’s juices and my semen, into her mouth, licking it clean.

I avoid focusing on my cock, watching Sayaka’s lips. Instantly, I’m aroused, craving to ravish her.

My cock hardens fully.

I’m getting horny too fast. I know why.

But more importantly…

I slowly focus on my cock again.

I can feel Sayaka’s tongue licking semen pooled under my glans.

So far, so good.

I focus more.

Now, from glans to shaft, I feel my sensitivity spiking.

I pour all my focus into my cock.

“Ugh…”

A sudden urge to cum surges, so I snap my focus away.

My senses return to normal.

Waiting for the urge to subside, I give Sayaka an order.

“Sayaka, make it intense.”

“Nfu, hai.”

With my cock in her mouth, she glances up, responding, and starts a vigorous, mouth-only piston motion.

Feels good.

Feels good, but it’s the usual sensation.

Five minutes of this, and I won’t cum.

Now, instead of gradually, I focus all at once on my cock.

Instantly, an insane pleasure assaults it.

“Guh… ah, cumming!”

Byuru! Byururu!

Too sudden, I can’t hold back, unloading into Sayaka’s mouth.

“Nn!? Nn, ngu, nn!”

Like Sheena, Sayaka didn’t expect such a quick cum. Her eyes widen, but she keeps her lips sealed, swallowing the torrent of semen.

“Kh, haa haa.”

As it ends, Sayaka’s suction draws out the last drop. I pat her head in thanks.

She smiles around my cock, purses her lips, and pulls off my glans with a “chupon” sound.

She kisses the tip, sucking with a “zuzo” noise.

The pleasure nearly lifts my hips, but I endure, waiting for her to finish before sitting up.

“I need to check something, so shower first.”

“Eh? Oh, okay.”

“Might’ve ranked up.”

“No way!”

Grinning at Sayaka’s puzzled response, she beams back.

Leaving her, I head naked to the living room, start the Magic Crystal, and check my mana.

Sanada Yagumo

Age: 25

Race: Human

Mana Capacity: C

“As expected, I ranked up.”

I felt lighter waking up, and my post-ejaculation arousal was faster, so I suspected it.

Power-leveling Sayaka and Gozaru’s group delayed it, but it took a while.

Fighting mostly E-rank goblins didn’t help.

Plus, since Rock and Saizou evolved, and Sayaka and Sheena joined combat, I’ve had fewer chances to fight directly.

Still, some of my summons’ experience must’ve trickled to me, letting me rank up.

That’s fine.

I glance at my flaccid cock.

Gripping it, it feels normal.

Focusing on it and gripping again, it’s like my nerves are exposed—hyper-sensitive.

“No doubt.”

Ranking up gave me the ability to heighten my cock’s sensitivity by focusing.

Probably because my ejaculation count jumped with this rank-up.

Maybe it’s to compensate.

Firing 14 times a day takes hours. This sensitivity boost could let me hit 20 or 30 in less time.

Is this a succubus dungeon-specific ability, or something implanted while I was unconscious during the abduction?

Can’t tell yet.

But one thing’s clear—

“Who benefits from this?!”

I slam the desk, yelling at the Queen, probably on the other side of the crystal.

Normally, you’d get an ability to heighten a woman’s sensitivity!

Or change your cock’s size! Or alter semen flavor! That’s what a magical dick does, right?!

Why boost my sensitivity?! That’s not it! That’s all wrong!

More ejaculations, so quicker cums? Safer in the dungeon if you finish fast?

Mind your own business! That’s just premature ejaculation! Premature ejaculation!

If Sayaka says, “That was quick,” or Sheena smirks with her blank face, even I’d be hurt!

“…This ability’s sealed.”

No one gains. I’d just get branded a quick shot, taking the biggest loss.

I know how it activates. Avoid focusing too much on my cock, and I’m fine.

Seriously, if you’re giving me a special ability, make it one that boosts women’s sensitivity.

Then I could make them cum repeatedly… wait, hold on?

Huh? Could this be…

Using the sensitivity boost (cock-only) lets me cum back-to-back, like earlier.

That means I can force consecutive climaxes, right?

If I tell Sayaka and Sheena about this ability beforehand, I can avoid the quick-shot label.

Then, in bed, rapid-fire cumming would…

Heh heh heh, got it. That’s an option.

I can rack up ejaculations and satisfy Sayaka and Sheena. Two birds, one stone.

The succubi thought this through.

For slaves only, but it’s a solid ability.

First, I need to test how many shots it takes to quell my arousal.

Good thing it’s a rest day with plenty of time.

I’ll save rapid-fire for tonight. If they pass out, it’d ruin the day off.

Planning done, I head to the bathroom where Sayaka and Sheena wait.

They wash me, exchanging occasional kisses, and I take Sayaka from behind, hands on the mirror.

After a refreshing shower, while they dry their hair, I buy breakfast.

For the 8th Floor victory celebration, I stock the fridge with Sheena’s favorite carrot sweets.

I grab some of Sayaka’s matcha desserts too, looking forward to Sheena’s joy.

When Sheena, done drying her hair, opens the fridge for carrot juice, she freezes, then looks at me.

I nod, smiling, saying it’s a victory celebration, and her ears twitch, tail wags, thrilled.

As thanks, she grabs as much carrot juice, cake, and pudding as she can carry and kisses my cheek. She’s really happy.

Sayaka gives a wry smile but agrees it’s fine for a celebration.

We eat breakfast, watching Sheena devour carrot cakes, then watch a movie.

Midway, Sheena, stuffed, rests her head on my shoulder, exhausted. She’s surprisingly clingy, so I let her be.

After the movie, I hit record on my phone, and on the sofa, we take turns in clothed cowgirl, one shot each.

After lunch, we play a strip-game. Once naked, we switch to a rule: losers get Pink Rotors on their nipples.

If I lose, no one cares, so I get to put one clothing item back on.

Sayaka writhes with rotors on both nipples, while Sheena, with rotors on nipples, clit, and inside her pussy, convulses. I carry them to the bedroom and go wild.

By the way, I bought five more Pink Rotors. Looks like a long-term relationship with these toys.
