Chika was violated by a goblin inside the exhaust duct.

As she was spanked on the buttocks and repeatedly ejaculated into, Chika was brought to orgasm so many times that she lost consciousness... When she next woke up, she was at the entrance leading to the exhaust duct.

"Hmm, uh... Ah, this is... the starting point..."

Holding her head, Chika sat up, and once she realized where she was, at the same time, a display appeared in front of Chika’s eyes.

"You have lost the ’Second Key’."

"Ah... I’ve lost it again... Considering that it was fine when I was in the orgasm beam passage, I guess it’s designed so that I lose it when I lose consciousness and the system resets my position..."

Seeing the same message displayed when she lost "Key 1," Chika looked anxious, but...

This was not a situation where she could afford to worry about it.

Regaining her composure, she stood up and subtly shifted her gaze to the right.

"Gugyagya!"

"Gugyagya! Gugyagya!"

"Gugya! Gugyagugya!"

"...♡ That goblin dick...it was amazing...♡"

"While I was unable to move easily, I was violated by an opponent who could easily be defeated with a weapon...♡ Mmm... haaa ...♡ It was so frustrating and humiliating... and yet it felt so good...♡ It’s the worst... and the best...♡"

"After all, being violated requires a partner, right...? ♡"

In her line of sight were the goblins, once again locked up in prison.

As they gazed at her with desire, Chika felt her pussy tingle with heat.

She was beginning to recall what had happened to her earlier in the exhaust duct.

"Ahhh...♡ I want to be done again...I want to be done in many different ways...♡"

"Okay... let’s give it a try... let’s dive into the exhaust duct again... ♡"

Apparently not entirely satisfied with the goblin rape she’d just experienced, Chika, her face flushed, headed toward the table on the right.

"...Huh. Part of the map is now visible...Ah, it seems that each time you fail, more information about the map is revealed."

Before pressing the switch, Chika glanced at the map on the panel and realized that some of its contents had already been revealed.

She then picked up the paper that was lying there and began to read the additional explanation.

According to that, if you fail, 10% of the route you have taken and the parts you have not taken will be randomly revealed before you even press the switch.

Once more than 70% of the disclosed map information is available, you will be able to check the map information within the exhaust duct, including your current location, from the menu.

Furthermore, the iron grate connected to the exhaust duct would remain open without having to press a switch... meaning that it would be possible to prevent the goblin pursuers from coming.

"I see... Well, for now I still want to be violated by goblins, so I don’t need to worry about it too much...♡"

"For now, I’ll just look at the map for 30 seconds like before, and then head into the exhaust duct... Once I’ve decided that, start...!"

However, since she wasn’t in the mood to seriously try to complete it right now, Chika only half-read what was being said and quickly pressed the switch that was beside her.

"Hmm hmm... Hmm hmm... Okay. Let’s go...!"

The map was incredibly complex, with everything displayed once again.

However, having already seen it once, Chika was mentally prepared and calmly looked at the map.

She entered the exhaust duct when the countdown reached "30".

"Hmm, hmm..."

Chika calmly and steadily made her way through the exhaust duct.

This time, she had carefully checked the route to the first small room, which was her initial destination, so she had no hesitation in moving forward.

"Gugyagya..."

"Gugya, Gugya..."

"Gugyagya..."

"Looks like the goblins have come in too...♡ ...Hehe..."

As they proceeded, it seemed that 30 seconds had passed, and they sensed from the cries that the goblins had also entered the exhaust duct.

Chika continued on, her face flushed, and arrived at the small room.

"We’ve arrived... Hmm, now what should I do from here..."

The small room was a narrow space, about one meter in both length and width.

Aside from the exhaust duct from which Chika had just emerged, there were a total of three exhaust duct entrances: one on the front wall and one on each of the left and right walls.

For the time being, this was her destination.

Chika hadn’t thought about what to do next, so she sat down and began to think.

"Hmm... but if the path you take is reflected on the map, then I guess there’s some meaning in just going wherever your whim takes you."

"Well then, let’s go with the front one for now..."

However, since she had no intention of clearing the challenge this time, Chika didn’t seem to feel the need to think about it that seriously, and she stood up.

She was about to enter the exhaust duct on the wall in front of it... when she stopped moving.

"Uh...it’s so small...it’s going to be hard to get in."

However, that exhaust duct was less than half the size of the one Chika had just used, and it looked like it would be quite difficult to get in.

"This is... hmm... I’ll go with a different one..."

Either her breasts or her buttocks would definitely get caught.

Sensing this, Chika averted her gaze and turned her eyes to the exhaust duct on the left wall—about the same size as the one she had just used, small enough to crawl through on all fours—and then entered it.

"Hmm... hmm..."

From this point onward, she wasn’t familiar with the route.

Chika wandered aimlessly, left and right.

"Ah... I couldn’t really tell what this was from the map."

"It’s possible to move from one exhaust duct to another, even from within the same duct... but given its size, it’s probably only for goblins... I wish I could use it too... Anyway, let’s move on."

And so she continued on.

Chika noticed that there was a hole in the exhaust duct that could move up and down horizontally.

However, judging from the size of the hole and its inconvenient location, she concluded that it was a tool the goblins used to move between exhaust ducts, and she stopped worrying about it and started moving again. 𝗳𝚛𝚎𝚎𝘄𝕖𝕓𝕟𝕠𝚟𝚎𝕝.𝗰𝕠𝐦

"Hmm... I can’t seem to find one... or rather, considering there are only three of them, it’s probably quite difficult to encounter one..."

After walking for a few minutes...

Chika was gradually becoming impatient with her inability to encounter any goblins.

After all, this exhaust duct labyrinth was quite large.

But there were only three goblins pursuing her.

Considering there were five exhaust ducts to enter through, the most likely encounter was right after entering.

As time went on, encountering them became a matter of luck.

Therefore, Chika became anxious that they would never meet if things continued this way.

She thought about starting over and opened the menu...

"Oh, they have something like this... How thoughtful ♡ Well then, let’s get started... Here we go ♡"

Next to the command to exit the exhaust duct and start over, she found a command called "Summon Goblin"... a command that allowed you to summon any number of goblins within a radius of 10 meters, inside the same exhaust duct, and she smiled.

Chika immediately selected that command. Having been violated by one earlier, she summoned two goblins.

"Gugya...? Gugya, Gugya..."

"Gugyagya...? Gugyagya..."

"Ahaha...♡ A goblin is very close...♡ Yes...♡"

Then, goblin cries began to be heard from both in front of and behind Chika.

Chika smiled at the sound of the cry.

She deliberately pounded hard against the wall to let the goblins know of her presence.

"Gugya!? Gugyagugya!"

"Gugyagya! Gugya!"

"Come on...♡"

Drawn in by the sound, the goblins began to cry out and approach the source of the sound...toward Chika.

Chika waited with a smile on her face as the goblins approached, their exhaust ducts rumbling loudly as they went closer.
