Willpower is stronger than drugs.
Did the aphrodisiac lose some of its potency because it dissolved into the hot spring?
No.
The aphrodisiac is working.
I could tell simply by watching Eris, who had come out of the water and was drying her hair. When I tried to dry her body with a towel, she said she would do it herself and wiped herself down, flinching with every touch.
It wasn’t as though soaking in the aphrodisiac hot spring had instantly turned her entire body into an erogenous zone.
But at least while the effects of the aphrodisiac lasted, it seemed true that her whole body had become somewhat more sensitive.
Even so, Eris put every ounce of passion and enthusiasm into tormenting my cock with her mouth.
She sucked so diligently that my knees began to ache. She worked my cock with astonishing fervor.
In the end, I came again.
Even when I came a second time, it splattered across her face. Yet afterward, Eris closed her eyes and smiled like a knight who had won a duel.
Even though I had splashed my cum across her face, when I grew furious and grumbled about it, she only smiled innocently.
‘Let her keep misunderstanding things like this.’
The instructor is weak to fellatio.
Even if that sort of misunderstanding continued, Eris would eventually learn the truth. But by then, she would already have become a master of fellatio.
Until that time, whenever Eris sucked my cock, I should let her remain as spirited as possible.
That’s what I told myself.
‘But that only applies while she’s sucking my cock.’
It was a different story for her to remain so full of vigor even when she wasn’t sucking my cock.
“Eris.”
“W-what is it?”
“Lie down.”
I prepared the bed.
It wasn’t a fabric bed, but a simple bed whose cushion had been waterproofed with glue.
In other words, it was a massage table.
There was no hole for her face, but Eris could tell what it was meant for the moment she saw it.
“W-why is this here?!”
“Obviously, I brought it over from where it was.”
The wall-vagina room.
It was one of the beds made so that the succubi could lie comfortably beyond the holes.
I had detached one and carried it here myself.
“Y-you’re planning to fuck me like that?! To make me lie face-down and then ram your cock into me from behind like crazy?!”
“Who knows?”
I was already completely satisfied after ejaculating twice, yet the damn thing was already stiff again at the thought of training Eris some more.
“Shut up and get facedown.”
“Ugh...”
At my command, Eris barely managed to move her feet and approached the massage table.
“D-did it get longer than before...?”
“Of course. I put two together.”
The beds in the wall-vagina room had been made on the assumption that only the upper body would lie facedown.
With two of them joined together, there was more than enough room for her entire body to lie flat.
“What are you waiting for? Climb up and lie facedown. Or do you want me to ram my cock into you just like that? Like a dog?”
“Uh, um...”
Eris placed her hands on the massage table and hesitated.
‘Could it be?’
Did this woman want me to fuck her like a dog?
Had the aphrodisiac made her that sensitive?
‘But I can’t just put it in that easily.’
Eris’s reason might not want it, but her pussy wanted my cock right now.
It was probably about 89.2 percent because of the aphrodisiac, but the rest had to be instinct—the instinct that craved the pleasure of being taken from behind and stimulated at the deepest point.
‘Even if it’s the other way around, it doesn’t matter. I have no intention of putting my cock in her right now.’
Not yet. For now, I would stimulate something other than my cock.
“Get up there.”
Rather than approaching Eris from behind, I moved to her side and pulled her body toward me.
Flinching at my touch, Eris climbed onto the massage table and lay flat on her stomach.
‘That’s it.’
She wasn’t wearing a massage gown.
She wasn’t even wearing underwear.
She was completely naked.
The only thing covering her was the towel wrapped around her hair, which left her white body exposed from the nape of her neck downward.
“Eris.”
I lightly relaxed my grip, then pressed both thumbs firmly into Eris’s back.
“!!!!”
Eris’s legs folded.
Her toes curled up for an instant. She looked at me with startled eyes, then quickly turned her head away again.
Press. Press.
I focused on stimulating her lower back.
As I pressed with my thumbs, the rest of my fingers stimulated her body as well.
“Ah, ahh...?!”
Massage existed in this world, too.
There was no system quite like modern massage, but there were certainly massages designed to loosen tense muscles.
‘But this is a massage for sex.’
There were different kinds of massage.
There was even the so-called erotic massage, where the purpose of the massage was sex.
When I used to visit brothels, I had seen some of the women massage male customers like this.
Someone might think that was the opposite of an erotic massage, but men and women were the same when it came to calling in an attractive member of the opposite sex for sex and pleasure.
Me?
I hadn’t sold my body.
I had simply learned massage for free by practicing on my ex-girlfriend’s body.
I learned while enduring plenty of abuse, but sometimes I had also put my cock inside her and had sex.
‘Come to think of it, maybe that woman had trained me.’
“If you’re satisfied with the massage, I’ll let you put it in.”
Press.
“Ahh?!”
The entire purpose of the massage in the first place must have been to feel pleasure from a man’s touch.
And in most of those massages, I had given them pleasure and fucked their pussies.
They had offered themselves to me, so I wouldn’t curse them for that part. And since it was still useful now, I decided to be grateful.
“You’re enjoying this.”
“N-no, I’m not. I’m just sensitive because of the aphrodisiac...”
“Liar.”
“!!”
I pressed my thumbs firmly upward along her spine. Keeping my body as close to hers as possible, I moved my hands upward in long strokes.
“You really didn’t feel anything? It looked like you almost came just now.”
“I did not come. Even if I had, it was only because...!”
“Really?”
I quietly continued massaging her back.
After reaching the top, both hands moved downward again. The moment they neared her buttocks, Eris tensed her buttocks and drew her legs together.
“Hah.”
Had she thought my hands were headed for her pussy?
She pressed her thighs tightly together to protect it, but I paid no attention and firmly pressed her thighs with all ten fingers.
“Ah, ahh...”
It wasn’t a moan soaked in pleasure.
“...Hah?!”
That was precisely why Eris must have been even more surprised.
The pleasure of having one’s muscles relax and the fatigue washed out of one’s entire body was a sensation entirely different from sexual pleasure.
“Ugh, ngh...”
Still, she must have been embarrassed to make such noises while naked—and toward the man who had raped her, no less.
‘Let’s see how long you can hold out.’
I was getting hard too, but after years of experience, I could endure something like this easily enough.
Press. Press.
I continued caressing and stimulating her entire body with my hands.
As I worked on the places where her muscles were knotted, Eris’s tense body slowly began to relax.
‘Now.’
Squelch.
“!!!”
Without any warning, I shoved my hand between her buttocks. Eris startled and clenched her cheeks.
“W-what are you doing...!”
“You’re wet.”
Eris reacted quickly, but my fingers were already inside her pussy.
“I don’t think this wetness is from the hot spring.”
I swirled my index and middle fingers inside her slick pussy.
Then I pulled them out and, right in front of Eris’s eyes, pressed my two fingers together with my thumb before drawing them apart.
Squelch.
A transparent, viscous fluid stretched out in a long strand.
Eris’s face flushed, and she lowered her head deeply.
“How are you going to explain this?”
“Th-that’s...”
Eris fidgeted before finally saying—
“...I-it’s because of the aphrodisiac!”
She shouted at me, raising her voice in anger.
“It’s the aphrodisiac! I’m excited because of the aphrodisiac!”
“Oh? Is that so? I thought your body was wet because you wanted my cock inside you.”
“Th-that’s...!”
For an instant, Eris’s eyes darted rapidly from side to side.
“H-ha... haha! You’re the one who wants to fuck me!”
I could already see right through her, but Eris held her head high as though nothing was wrong.
“Aren’t you trying to fuck me like a dog again?! Just like last time, when you made me lie facedown on the bed and raped me!”
“No, I’m not.”
“......You’re not?”
“No.”
I pressed down on Eris’s back with one hand.
“Even without putting my cock inside you, I can make you come as much as I want with just my hand.”
I thrust my other hand between her buttocks, curled my fingers like a hook, and pushed them inside her pussy.
Squelch.
“......!!”
“There’s no need to hold back. This is practically the same as drawing the aphrodisiac out of your body.”
“D-draw out the aphrodisiac...?”
“I’ve confirmed that the effect is sufficient, so of course I need to get rid of the aphrodisiac that remains in you. Or were you planning to return to your room while still filled with it?”
“Th-that...!”
“You only need to let it out obediently.”
I moved my fingers rapidly back and forth.
It was far inferior to a cock, but Eris’s legs stretched out below her, and her toes merely continued curling and uncurling.
“Ah, ngh, ahh...!”
I could feel Eris’s climax gradually building.
But simply stimulating her with my fingers like this seemed insufficient.
‘It can’t be helped.’
I lowered my upper body without letting Eris notice. Then, following the rhythm of her trembling movements—
Lick.
“!!!”
I kissed the back of her shoulder, lightly biting it.
Fwoosh!!
As though someone had pressed a climax switch, Eris gushed out a flood of liquid.
The bed became soaked in an instant, and the transparent fluid flowed down both sides in steady drips.
“.......”
Eris’s face was flushed all the way to her ears. She could do nothing but keep her head bowed.
Squelch.
My fingers were still working inside her pussy.
“The aphrodisiac is definitely effective. Isn’t it?”
“.......”
Without saying a word, Eris gave the slightest nod.
