After navigating the exhaust duct maze.

Chika had started down yet another new path.

And then she moved forward a little.

A treasure chest appeared before Chika’s eyes.

"Oh, a treasure chest... and yes, there’s a key too. That clears the 3rd floor."

Since it was a single path from the first corridor to this point, the treasure chest did indeed contain the key marked "3". 𝙛𝒓𝒆𝙚𝒘𝒆𝓫𝙣𝓸𝙫𝓮𝒍.𝒄𝒐𝓶

Chika picked it up, nodded with satisfaction, and then stepped onto the emblem, which was a return point behind the treasure chest, and returned to the room with the first elevator.

"Phew... Well, I’ve played quite a bit, so I’ll stop here for today and do the final 4th floor tomorrow."

When she returned, Chika said this, fiddled with the menu, and logged out.

And then, the next day.

Chika, having logged in, took the elevator to the 4th floor.

"Well... there’s only one passageway here too."

The area beyond the elevator was the same interior as the previous floors.

Behind the elevator she just used, there was another elevator with the number "4" on the door that goes to the upper floors.

Items such as a showerhead, bed, shelves, and safe.

And there was only one passageway in front of her.

Since there were no other passages, Chika nodded and slowly began to walk down the corridor.

"...This place is..."

After walking down the corridor for a while...

The corridor ended, and a room appeared before Chika.

"A big room... um... what do we do here...?"

The room was about the size of a school gymnasium.

On the opposite side, there was a passageway leading further ahead, but it was blocked by iron bars and could not be accessed at this time.

In the center of the room, a huge board with nine squares arranged vertically and nine horizontally, reminiscent of board games such as chess, shogi, and Othello, was set on the floor.

The squares were approximately two meters in both length and width.

And in front of that board, there was something resembling a panel attached to a rod extending from the floor.

Having confirmed all of that, Chika headed back to the panel and began reading the paper that had been placed with it...the instruction manual.

"...I guess it’s something like playing a board game..."

According to the plan, the activities in this room would be exactly as imagined: competitive board games like chess or shogi.

However, the fighting style was quite unique.

First, you needed to touch the panel in front of you and select "Start."

Then, on the opposite side from where Chika was currently standing...ten pieces would be set up on the side that would be her opponent’s.

There was one type of piece: "King".

The remaining nine slots would be filled with randomly selected monsters, who would be placed as "soldiers."

In contrast, Chika herself would assume the role of the "King" piece, and no other pieces would be added.

After that, like in chess or shogi, players moved only one piece per turn, capturing pieces and so on.

The rule was that the first player to remove the opponent’s "king" piece would win.

Up to this point, Chika was at a significant disadvantage... or rather, she had virtually no chance of winning... but there were still more rules to follow.

"Wow...♡ This might be amazing...♡"

First, let’s look at how the pieces move.

The opponent’s pieces could move a limited number of spaces at a time: the "King" could move two spaces, while "Soldiers" could only move one space.

In contrast, Chika could move up to three spaces at a time.

Next, let’s look at how to capture pieces.

In chess or shogi, the player who goes to take the piece usually gets it.

In this board game, you’d be fighting with "sex."

The rules stipulated that the first person to pass out or ejaculate five times would lose.

Since Chika didn’t have a penis to ejaculate, the only way she could lose was to faint... but conversely, as long as she didn’t faint, no matter how much she was made to orgasm, she wouldn’t lose.

And apparently the other side was unaware of the rule that the first one to ejaculate five times loses. So they would keep trying to ejaculate without any hesitation.

In other words, to put it extremely, as long as Chika’s stamina lasted, she would never lose and could capture the opponent’s pieces one after another.

Also, if Chika fainted and lost, she could try again as soon as she woke up.

In that case, Chika’s physical strength would be fully restored.

The opponent’s pieces would be reduced by the number of pieces you had already eliminated, and the number of ejaculations would also be counted.

Therefore, the system was designed so that Chika would gain an advantage with each subsequent attempt.

"I see... Okay, I understand."

"Well then... let’s get started...!"

Having understood the rules, Chika immediately touched the panel and pressed start.

At that moment.

Chika’s body disappeared... and she was teleported onto the board.

"Uh...! Um... that’s the enemy..."

Chika was located in the center of the foreground.

Standing there, Chika turned her gaze to the other side...toward the other players.

"Gugyagya!"

"Gya gya!"

"Woo, ooooh"

"BOOM...! Boomoooo!"

"Grrrr..."

"Woooo..."

There were three goblins, one zombie monster, two wolves, and three orcs there.

And there was one mummy wearing a crown, as a "king."

In terms of arrangement, the "King" was positioned in the center on the opposite side. The remaining monsters were positioned to surround it.

"Gugyagya!"

"Bumoooo! Boom!"

"Butt!"

"Gugya! Gugyagugya!"

The monsters seemed to have immediately noticed the naked, busty beauty, Chika, on the other side, and they let out excited cries, their penises dangling from their waists becoming hot.

"Hmm...♡...Okay...then...let’s get started...!"

As Chika was about to get excited by his excitement and lewd gaze, the game started with Chika taking the lead.

Incidentally, there was a time limit before you could move a piece; if you didn’t move a piece for more than a minute, it became your opponent’s turn.

Seeing the countdown to "60" indicating the time limit begin, Chika immediately moved three spaces forward.

The opponent was positioned two squares from the back, and the goblin that was directly in front of Chika moved one square forward.

At this point, if Chika had moved three spaces forward, she could have initiated sex with the goblin, but Chika deliberately moved only one space forward.

The goblins then moved forward.

This meant Chika and the goblin were facing each other, and if Chika had moved forward, they would have had sex this time...but at this point, Chika moved one square backward.

"I want to keep my distance from other monsters the first time we do it...♡"

The reason was that after sex, she didn’t know what state she’d be in.

Even if she didn’t faint after winning the match, it was possible that being sexually assaulted so much had left her body weak and unable to move.

Unless the turn didn’t change unless you made a move, since it automatically became the opponent’s turn after one minute, the plan was to create some distance between herself and other monsters beforehand, thereby giving herself some time to recover her health.

"Gugya! Gugya!"

"Come on... come over here... ♡"

It seemed they were unaware of Chika’s intentions.

The goblin moved one more square forward, finally reaching Chika.

In response, Chika moved one square backward.

And the goblins followed suit, moving forward as well.

"Is that enough...? Okay, then let’s have a sex battle with the goblin...! ♡"

"Okay... I’ll take on the challenge... ♡"

"Gugya! Gugyagugya!"

This allowed her to get some distance away from the other monsters.

Therefore, Chika moved forward and entered the same square as the goblin.

Then at that moment, a glass-like plate rose from the floor at the edge of the box, preventing you from leaving the box.

The goblin then lunged at Chika.

Unable to avoid it, Chika was thrown to the ground by the force of the attack.
