I Became a Prisoner Trainer in the Dungeon.

Episode 63: Hot Spring Of Aphrodisiac (1)

[A short while later, in a certain area of the training room.]

It’s still surprising, but the power of magic is truly amazing.

‘To create this much hot water in a place where there is no water.’

Swish, swish.

Supply succubus Natalie lightly waved her staff, and water poured out from the air, gushing into a deeply dug pit below.

Calling it a pit is a bit of a stretch.

Initially, I considered a circular shape, but due to the dungeon’s structure, digging a circle could cause other problems, so a rectangular pit turned out to be more convenient.

How did they dig it so precisely into a rectangle, you ask?

They dug out the earth and then used wind cutter magic to shape the ground.

And they finished the walls well, so the walls and floor of the pit were neatly arranged.

Thanks to that.

“Is this temperature of hot water sufficient?”

“Yes. Perfect.”

The water was clean, and I reached out my hand toward the water filling the pit.

The water temperature was perfect.

It was probably around 42 degrees Celsius.

It was about the same heat level as the hottest part of a sauna bath, so I immediately wanted to get in.

‘To think they can do this much with the power of magic.’

There was no water source here.

Just like the ‘wall-peeping’ room, it was just a hole dug in one area of the training room.

There were no water pipes, let alone flowing underground water.

They simply filled it with water using the power of magic.

‘It’s really amazing.’

Magic was a miracle that could not be explained by science.

But it was not like I was going to research or learn magic right now.

Once, during my adventurer days, I tried to see if I could learn magic and walk the path of a mage.

-You have no talent.

The result of being used as a slave for a month under a certain bastard mage was disastrous.

Magic was not my path.

‘But I have the brain to use it.’

Where this water came from.

Those magical principles were not important.

Whether it was drawing moisture from the air or mana sparkling in the form of water, the important thing was that hot water had filled a small drum-sized pit.

“Confirmed safe for skin contact. Confirmed safe for drinking. The rest…ooph.”

I threw off my clothes in one go and put my body into the pit.

Splash.

“Confirmed that my feet touch the bottom and no residue comes off the pit walls.”

Because of my height, the water reached just around my chest.

Since it was made with the physique of the person entering this pool in mind, it was natural that it would reach this height for me, who had a physique well over 180cm after reincarnation.

‘Since there are no worrying parts, I can train safely and hygienically.’

Confirmation complete.

I got out of the pit.

Creak.

Just then, the door opened.

“Trainer. I brought Eris….”

“Oh, good. You came at just the right time.”

Lilith, holding the chain, brought Eris in.

Eris hesitated and looked at me, then quickly turned her gaze away.

“…Natalie. Why aren’t you drying the trainer off?”

“S-sorry.”

Lilith scolded Natalie.

I didn’t particularly ask for that, but Lilith was more concerned about my condition than I thought.

Rustle, rustle.

Natalie dried me with a towel.

It felt strange to be dried like this for the first time, but it was not bad since a beautiful woman was serving me.

“Eris.”

“……”

“You’ve showered in solitary confinement, but you haven’t taken a bath, have you?”

“Th-that’s.”

“Get in.”

I pointed to the pool I had just gotten out of.

“……What are you thinking?”

Eris hesitated, looking at the succubi.

“Well, isn’t there only one thing I could be thinking? You two, wait outside for a moment.”

“Understood. Please call us immediately if you need anything.”

Following my instructions, Lilith took Natalie outside.

The only people left in the training room, which looked like a university lecture hall, were me and Eris.

“Get in.”

“……”

Eris moved slowly, wary of me.

‘It was a good thing I got in beforehand.’

If it had just been still water, Eris would have asked questions and tried not to get in.

But since she saw me get in and out, she probably thought it was relatively safe.

Rustle.

Eris lightly touched the water with her toes.

She seemed a bit surprised by the temperature of the hot water, but she soon sat on the edge of the pit.

“I-it’s not going to suddenly sink to the bottom, is it?”

“……”

“H-how deep is it? I, I can’t swim.”

I gained some knowledge.

She seems to like getting into the hot water, but she must be wondering if the bottom was really there.

“Then hold my hand and get in.”

“……”

“Don’t want to? Or should I kick you in from behind?”

“N-no, I understand.”

Eris reached out her handcuffed hands to me, and I held her two hands tightly.

Splash.

Eris held my hands tightly and went into the water.

Every action was slow, but Eris closed her eyes tightly and slowly went into the water.

“……”

She went in and immediately blushed, lowering her head.

Naturally, her feet reached the bottom, and even without standing on her tiptoes, her neck didn’t touch the water when her feet were flat.

‘This is it.’

Just enough to submerge up to the upper part of her chest.

It felt like the pit was about 5cm lower than designed, but it was not a big problem.

“……H-hand.”

Eris fidgeted with her hands.

I let go of Eris’s hands and sat cross-legged in front of her.

“Eris.”

“Y-yes. What are you trying to say—”

“From now on, I’m going to use you to test the effects of this ‘aphrodisiac pool.’”

“……What?”

Eris’s expression, looking up at me, instantly hardened.

“What, pool?”

“Aphrodisiac pool. I haven’t decided on an official name yet, but I guess I’ll call it the aphrodisiac hot spring.”

Calling it an aphrodisiac bathtub sounded a bit off, but calling it a hot spring made it sound more sophisticated, didn’t it?

“From now on, I plan to turn your entire body below the neck into an erogenous zone.”

“Wh-what…?!”

Eris tried to jump out in a hurry, but—

“Where do you think you’re going?”

“Kuh?!”

Eris couldn’t even resist my touch and was pushed back into the hot spring.

I grabbed the crown of her head and lightly pushed her head into the water, causing the water to surge below.

Bubble, bubble.

Momentarily, bubbles rose, and I held my breath for a moment before letting go of her hand.

“Puhah!”

Eris coughed out water.

Her face was filled with embarrassment, and she breathed heavily.

“Y-you…!”

“……”

Without a word, I looked down at her, holding her crown with my hand, and Eris soon bit her lower lip and lowered her head.

“Kuh….”

Humiliation and shame.

And a slight sense of betrayal flickered in her eyes.

She probably didn’t expect me to treat her like this, but in fact, what Eris was supposed to experience was much worse training than this.

‘Humans tend to get endlessly complacent when you treat them well.’

I didn’t particularly have any bad feelings toward Eris.

I had already confirmed the effects of the aphrodisiac, but this training was necessary to test how much I could utilize it.

Eris’s only fault was that she hadn’t fallen deep enough into depravity to become a vampire yet.

If she became more soaked in pleasure, she might one day willingly shout, “Yes, I will!” when I say, “I’ll give you my dick when you become a vampire,” without giving her my dick.

She was not at that stage yet.

That was why I needed to do this work now to bring her to that stage.

To make her aroused with her vaginal fluids flowing just from the wind brushing against her thighs.

To make her heart race just from smelling my dick’s scent.

‘But at least it’s not below the neck, right?’

Click.

“Huk…?!”

I opened the lid of the aphrodisiac I had prepared in advance.

Eris kept her mouth tightly closed, only blinking her eyes.

“Eris.”

I dripped the aphrodisiac down in front of Eris’s eyes so she could see it.

“Consider yourself lucky.”

“Lucky? When you’re about to put me in water filled with aphrodisiac…!”

“Next time, I’ll put you in slime instead of water.”

“!!!”

Eris’s expression instantly turned pale at my words.

“S-slime?!”

“Yeah. You’re getting special treatment with the hot spring, this place is actually a slime pit, you know?”

I pointed to another hole that hadn’t been cleaned up yet.

“That’s where the slime will be, completely covering your body and sticking to you.”

“U-uh…!”

Eris swallowed.

She seemed to feel like she was being subjected to it just from imagining it, her body trembling and her head slightly lowered.

“Why…why are you doing this?”

“N-no, nothing!”

Eris vigorously shook her head.

I didn’t intend to go that far either, but if Eris wanted it—

‘I should do it, not the slime.’

I didn’t have a fetish for doing it in water, but I was curious since I had never done it before.

Having sex in the sea.

Having sex in the swimming pool.

The very idea of having sex in water was a bit strange, but trying something new was fun, wasn’t it?

“Good, Eris.”

I stroked Eris’s wet hair, smoothing it into an apple shape.

I wondered if I should have tied it up before she got into the water, but Eris was quite pretty even with wet hair.

And—

“……!!”

Eris suddenly lowered her head.

At the same time, she fidgeted with her two hands, which were the only parts outside the water, in front of my legs, and began to breathe heavily.

“Eris.”

I slightly raised my body and knelt in front of Eris, taking a stance.

“What are you doing?”

“J-just a moment. Why is that….”

“It’s the perfect position.”

It would be more suitable if I sat with my buttocks on the edge, but I didn’t intend to turn my own lower body into an erogenous zone with the effects of the aphrodisiac hot spring.

Instead.

“Stand on your tiptoes.”

All Eris had to do was raise her body slightly.

“Suck it.”

I lowered my hard, erect dick with my hand, aiming it precisely at Eris’s face.

“Suck it with your mouth.”

Not a creampie, but—

‘It’s about time I received some fellatio service.’

After fucking Eris repeatedly for the past few weeks.

“Kuh….”

Eris only bit her lower lip as if she was humiliated, but she didn’t try to bite my dick.

“J-just suck it?”

Instead, she caressed my dick with both hands, bringing her face closer to the tip.

“Yes. If you make me cum now….”

Smirk.

“I’ll let you rest in a bathtub without aphrodisiac, not this aphrodisiac hot spring.”
