Chika began climbing the nine-meter-high wall.

This time, since she had checked the route to some extent beforehand, she was able to climb smoothly.

"Mmm... heave... ♡ Heave, heave... ♡"

She grabbed a penis, stroked it until it was erect, and climbed up.

She wanted to stop and take a breather, but she knew from her first experience that if she stopped, the penis would ejaculate and lose its erection.

Chika continued climbing, keeping penises erect without rest.

"Hmm... Okay... Done!"

And in no time at all, Chika reached the top of the wall.

A passageway stretched out there, leading further ahead.

Further inside, there was a treasure chest, as if to indicate that climbing was no longer necessary, and behind it, on the floor, was an emblem marking the return point.

"Phew... This one was easier than the first floor. But the penalty game was pretty intense...♡"

"Anyway, let’s check the treasure chest...!"

Chika felt a slight sense of dissatisfaction that it was already over, but she was also satisfied because of the intense orgasmic frenzy she had experienced while being absorbed into the tentacle bed.

She stepped into the corridor and reached for the treasure chest.

"...Ah, there it is, key number ’2’! Yay...!"

Inside was a key, and Chika let out a cry of joy as she picked it up.

"I can’t believe I got it on the first try... I guess things like this really do happen."

"I’m interested in the other rooms I haven’t been to yet, but... there’s still half the floor left, so let’s go to the next floor...!"

With the key in her hand, she rejoiced.

Chika returned to the first room by activating the emblem, which served as a return point.

With a slightly wistful gaze directed toward the three corridors she hadn’t visited this time, she used the key she had just acquired to unlock the elevator marked "2" and stepped inside.

Then the elevator doors closed, and it began to rattle upwards... and as soon as it stopped moving, the doors opened.

"...Um...there’s no change to the room’s interior..."

The newly arrived third floor.

The room was square in shape.

Behind the elevator she just used, there was another elevator leading to the upper floor, with the number "3" written on its door and a keyhole in the center.

Various items such as a showerhead, towels, a bed, a refrigerator, and a safe were placed along the wall.

Up to this point, it was the same as the previous floors.

There was one big difference, though.

"But... there’s only one passageway left..."

There had been four corridors on the previous floor.

There was only one left, located directly in front of the elevator.

"If the number is going to decrease, maybe I should have gone to the corridors I hadn’t visited on the previous floor..."

"...No. But now that we’re down to one, the erotic events are likely to be more intense, so this might be enjoyable in its own way...♡"

Chika looked a little dissatisfied because the number of passageways had decreased... which meant fewer erotic events she could experience.

After thinking about it for a while, a smile appeared on her face.

"Okay... let’s go right away...!"

Chika decided to go right away.

She put the "2" key she was holding into her inventory and started to proceed down the only passageway.

And then she started moving forward for a little while.

In front of Chika, a passageway appeared where the ceiling, floor, and walls were all made of glass.

The passageway was about 30 meters long and 3 meters wide in both length and width.

At the end of the passageway, there was a normal passageway, but it was blocked by iron bars, making it impossible to proceed.

On the other side of the glass enclosure, there was a large number of machines that looked like they were designed to launch something.

And on the entrance side of the passageway, there was a stand with a switch installed and some paper placed on it.

"What’s this...? ...Oh, there’s some paper. Let’s see...?"

At first glance, it was not very clear.

With a sense of doubt, Chika picked up the paper and began to read its contents.

The content was an explanation of this glass-enclosed walkway.

The first thing to do was press the switch located on the stand.

Pressing this switch would open the iron bars at the end of the glass-enclosed walkway, allowing you to proceed further.

However, at the same time, the machines on the other side of the glass would also activate. They would start moving back and forth and side to side, while firing the orgasm beam that she had briefly experienced as a penalty during the dick bingo game on the first floor.

The text stated that if you were hit by the orgasm beam while walking down the corridor, the iron bars would come down again and would not open until you pressed the switch again.

"I see... So basically you’re going to do something like what thieves do in movies."

As Chika continued reading the explanation, in her mind, she pictured a thief dodging the infrared lasers installed in the corridor as he made his way through.

"And... that’s right. It’s not like it’s over right away after just one session, is it...? ♡"

And according to the subsequent explanation, the orgasm beam’s emission would stop five minutes after the iron bars came down.

However, the orgasm beam was so stimulating that even a single hit would instantly send you to orgasm.

It was practically impossible to escape to a safe zone after being hit. Furthermore, it was said that once you’ve been hit, all other orgasm beams would start targeting Chika herself.

In other words, if you were hit by it, you would be subjected to continuous orgasmic climaxes for five minutes straight, with the orgasm beam being fired all over your body.

"...Hehehe...♡ I wonder what it will feel like to endure this for five minutes...♡"

The pleasure of the orgasm beam she had received only three times on the first floor was resurfacing in Chika’s mind.

Chika was already excited by this opportunity, which came along just when she was thinking she wanted to savor it more.

"Okay... Let’s get started... ♡"

With the excitement beginning to build, Chika pressed the switch placed on the table.

Then, with a rattling sound, the iron bars at the end of the passageway began to open.

At the same time, the machines on the other side of the glass also activated. They began to emit a red light... an orgasm beam.

There were many of them, and their movements varied greatly.

For the first ten meters from the entrance, the projectiles were simply fired in a straight line in all directions—vertically, horizontally, and diagonally—and were not moving.

Within the next 10 meters, they moved around in a zigzag pattern.

In the last ten meters, they moved around in a complex manner, sometimes firing and sometimes not, making it extremely difficult to dodge.

"...Okay...Let’s go...♡"

Excited by the prospect of the orgasm beam, Chika headed toward the glass-enclosed corridor.

Into the passage from which many orgasm beams were being emitted, she stepped inside.
