There was a hidden underground room in the hut where Yakubi lived.

The room had a somewhat cluttered atmosphere, with several boxes filled with various tools lined up against the wall.

A single metal chair sat in the center of the room.

Shiori, who had been put to sleep with sleeping pills, was made to sit there.

"Mm, uh... huff... huff..."

"Well then..."

After seating her, Yakubi took out a set of metal shackles and began to restrain Shiori’s body.

He clasped both her hands behind her head and connected them to the back of the chair.

He spread both her legs wide, hooked them onto the armrests, and tied them to the chair.

In other words, Shiori, still asleep, was restrained in an M-shaped pose with her legs spread.

"Ahhh... so good... so erotic... hehe, hehehe..."

"Mmm, uhh... huff... huff..."

Having finished the restraints, Yakubi took a breath and began to carefully examine Shiori’s body once again.

Her chest trembled slightly with each breath.

A slender, exposed stomach and graceful arms.

Her beautiful legs were completely exposed, and her indigo-colored panties were fully visible as she sat with her legs spread in an M-shape.

After gazing at Shiori’s body—excessively exposed as befitting her erotic attire—as if licking her with his eyes, Yakubi gently reached out his hand... and began to touch.

"Ahhh... it feels so nice... this smooth skin... it feels so good... hehe, hehehe..."

"Mmm, mmm, mmm... mmm, mmm..."

Gently starting from her toes, Yakubi slowly stroked her shins, knees, and thighs with his palms, savoring the feel of her skin.

Next, he touched Shiori’s arm, tickled her exposed armpit, and stroked her neck.

Shiori let out a small cry at Yakubi’s touch... and then slowly opened her eyes.

"Ah, huh... where... huh!? Wh-what is this...!?"

"Is this... I’m being restrained...!?♡ And in this pose...!?♡"

She realized she had been moved from the room she’d been in just moments before to an unfamiliar place.

At the same time, realizing she was in an embarrassing position, Shiori let out a cry of excitement mixed with embarrassment.

"Oh, you’re awake already... This is my alchemy room."

"I’m going to take my time and thoroughly enjoy your beautiful, erotic body right here."

"W-what...! What are you saying...! C-c-c-release me from these restraints...! You, you...!"

"You’ve finally revealed your desires...!♡"

Yakubi’s eyes widened slightly at the realization that Shiori was already awake.

Since he had captured her, there was no need to worry about resistance, so Yakubi said this with a confident air.

Shiori reacted with surprise to those words and shook her body to try and break free from the restraints, but... she couldn’t get free.

"You can’t take them off. They’re incredibly sturdy."

"Stay quiet."

"Ah... no, ah...! Wh-where are you touching me... s-stop... mm, mmmhhhhh...♡"

"Ahhh... that’s such a naughty way to touch me...♡ It’s so frustrating... and this... is making me feel good...♡"

While Shiori offered only token resistance, Yakubi continued to stroke the exposed skin on her thighs and stomach.

The way he gently touched her, as if confirming the texture, was so frustrating that Shiori was slowly beginning to feel it.

"Mmm, uh...♡ Mmm, uh...♡ Ah, mmm... mmm...♡ Mmm... ah, ahh...♡"

"I’m only being touched so far, but...♡"

He stroked her thigh.

Stroked her belly.

Rubbed her armpit.

Stroked her waist.

Yakubi avoided touching sensitive areas like her breasts and pussy, instead slowly stroking only the exposed skin.

But even with such gentle caresses, Shiori was slowly but surely feeling it, and a sweetness was beginning to mix with the sounds she was making.

"Oh? Are you already feeling it? I’m only gently stroking this beautiful skin..."

"Well, you’re wearing such revealing, suggestive clothes. It wouldn’t be surprising if you’re a sensitive, horny girl like that."

"Uh... uh, mm, mm...♡ Uh, ah... ah, ah, mm...!♡ Mmm, mmm...♡"

"You’re being selfish...♡ ...But that’s true...♡"

Hearing Shiori’s sweet voice, Yakubi grinned and said this, then tickled her belly button.

As she cried out in response to the tickling, Shiori became increasingly aroused.

"Well then, let’s make that naughty girl feel even more pleasure."

"That’s why... I’ll put this on you."

"Hmm, haa... Wh-what does that mean...? Ah, ah..."

"Oh, an eye mask...?"

After thoroughly stroking Shiori’s skin, Yakubi took out a new, very simple black eye mask and put it on Shiori.

As a result, Shiori’s vision went completely dark, leaving her with no idea what Yakubi was going to do next.

"So... let’s start with this..."

"Ahhh... ahhh...!?♡"

"H-her white coat... so, does that mean... her chest is completely exposed...!?♡"

After putting on the eye mask, Yakubi immediately did something.

Shiori couldn’t see what was happening, but she immediately realized that the white coat covering her chest had been torn off, which heightened her excitement and shame.

"Oh... I knew they were big, but... wow... they’re beautifully shaped, gorgeous big breasts."

"Uh, uhh...♡"

"Y-you can see this... right...? My breasts are completely exposed...♡"

She could hear the sound of movement, but couldn’t tell where he was looking or what he was seeing.

Therefore, Shiori got excited as she fantasized in her mind.

"Hmm... it’s very soft, but it also has a definite firmness that pushes back against my fingers. The elasticity is perfect, making it very pleasant to massage."

"And these nipples... the color is beautiful. The shape of the areola is also beautiful."

"H-hmm...♡ Mm, mm, mmm...♡"

"N-no... don’t tell me...♡"

From somewhere, Yakubi lifted Shiori’s breasts from below and began to shake and knead them. Then, without touching the tips of her nipples, he gently stroked only her areolas while continuing to speak.

Shiori felt frustrated and embarrassed by the teasing, yet she was also aroused. 𝑓𝓇𝘦ℯ𝘸𝘦𝑏𝓃𝑜𝘷ℯ𝑙.𝑐𝑜𝓂

"What nice breasts... They’re really nice..."

"Mmm, uhh... mmm, ah... ah, mmm...♡"

"C-caress me... wait, breathing on me now... ahh, don’t do that ♡"

He touched her chest as if he were carefully examining it.

Furthermore, he blew breaths onto her nipples, making Shiori feel a shiver run down her spine.

"Ugh... It’s true... Not being able to see makes you feel things more intensely...♡ The way you touch me is frustrating, or rather, it’s so tantalizing... It sends shivers down my spine...♡"

"Mmm, mm, ah, mmm...♡ Mmm, ah... ah, ahn...♡"

Just when she thought he was only touching her chest, any part of her exposed skin was randomly stroked.

Because her vision was obscured, Shiori continued to feel things slowly but surely.

"Hehehe... Now, let me do this for you next."

"Mmm... Ah, ah...!?♡"

"W-what...?♡ What did you just put on my chest...?♡"

As he carefully touched her, Yakubi stopped for a moment, then poured some kind of thick liquid onto her chest.

As Shiori was inwardly surprised by the somewhat cool liquid, Yakubi spoke.

"Don’t worry, what I just put on was just lotion."

"How is it? Doesn’t the coolness feel nice?"

"Uh, mmm... ah, ahh...♡ Hmm, mmm... mm, mmm...♡"

"Just like that...♡ Ugh, maybe it’s because I don’t know how it was applied or what it feels like right now... but even just the sight of the lotion dripping makes me curious..."

Even after hearing those words, Shiori couldn’t feel relieved at all.

The lotion poured on her chest dripped down to her stomach.

It soaked into her skirt.

It started to run down toward her thighs.

As Yakubi said, it was much cooler and more viscous than the hot, rough hands of Yakubi that had been touching her body just moments before.

The difference in temperature and texture made the movement of the lotion even more vivid, and she was writhing in pleasure just from the way it dripped and moved on her skin.

"Hehehe..."

"Ahhh...!♡ Ah, hyah... uh, mm, ahh...!♡ Ah, mm... ahh, ah, aaah...!♡"

After applying a certain amount of lotion, Yakubi began touching Shiori’s body again.

However, the touching was mainly focused on the areas of skin that had been exposed from the beginning.

Even if he touched her breasts, he never touched the tips of her nipples, only stroking or lightly massaging the areola.

"This... is kind of... intense... being made to feel it slowly, not knowing what’s going to happen, being teased to an inappropriate degree... mmmh ♡ it’s... intense...♡"

"Ah, ah...♡ Mmm, mm... hah, aaah...♡ Aaah, aaah...♡"

Compared to being intensely aroused and brought to orgasm repeatedly, this was an overwhelmingly subtle attack.

Shiori was simply being teased and made to feel the sensations slowly and deliberately.

"Now then... I’ll keep going like this and let you feel me to your heart’s content..."

"Ahhh...♡ Ah, ah...ahhh♡ Ah, mmmhhh...♡"

"At the very least... even just a little bit would be fine, please let me come...♡"

The attacks from Yakubi continued.

Those words, which confirmed that fact, sent a shiver down Shiori’s spine.
