Chika had started the sandbox quest, "Investigation of Ruins."

Having had all her equipment taken from her at the entrance, leaving her completely naked, she walked for several hundred meters, squeezing her enormous breasts with both hands.

"We must be getting close to the center of the ruins now," Chika began to think, when the corridor ended and a room came into view.

"...Ah, the room...! You surprised me...Um..."

The moment Chika entered the room, a wall suddenly slammed down in front of the entrance leading to the corridor she had been walking through, making passage impossible.

Surprised by this, Chika began to look around the room again.

The room itself was square-shaped, measuring approximately 30 meters in both length and width.

There was a passageway in each of the four corners of the room.

At the center was a cylindrical column about five meters in diameter that reached the ceiling, and part of the column had a door that resembled an elevator.

The door had a large "1" written on it, and a keyhole was visible in the center.

The walls of the room were cluttered with various items, including a bed, a table, a refrigerator, and a safe.

Furthermore, a showerhead was protruding from the wall, and several towels were placed right next to it, so it seemed to be in usable condition.

"Hmm...the key is somewhere at the end of those four passages."

"So, if I find that and put it through the keyhole over there, I can go to the next floor, right?"

"I don’t know where it is... so I’ll try going through the nearest corridor for now."

She quickly checked the condition of the room, and after confirming what she should do, Chika started heading toward the nearest corridor.

"I wonder what’s there..."

Chika walked along the cobblestone path.

Chika proceeded, mentally bracing herself for a trap to activate at any moment, but nothing particularly happened, and she reached the next room.

"Where is this...?! Oh, is that...?"

The next room was rectangular in shape.

The distance between the opposite wall and the wall where Chika emerged from the corridor was approximately five meters.

The distance between the left and right walls was about ten meters.

There was another passageway directly opposite the one Chika entered through, but it was impassable at the moment due to a metal grate.

Next, the left and right walls.

There was nothing on the left wall, but...the right wall.

There was a hole in that area, right where Chika’s head would be when she was kneeling, and a penis about 20 centimeters long was sticking out of it.

"Oh, a penis... Ah, something’s written on it... Um..."

Blushing at the sight of the penis sticking out, Chika began reading the explanatory text written above it.

[Savor this dick and remember it!]

"Um, so does that mean... that I should put it in my mouth...?"

Because it was a concise explanation, after thinking for a moment and reading the contents, Chika, with a flushed face, gently knelt before the penis and began to gaze at it up close.

"I guess I have no choice but to do it, since the iron bars won’t open unless I take it in my mouth...♡ Mm, mmm..."

Nobody in particular was listening, but after muttering that to herself, Chika placed both hands against the wall and gently brought her face closer... and took the penis into her mouth.

"Mmm, uh... mm, mm..."

"This is what this dick tastes like...♡"

"Hmm, the iron bars won’t open... Is it not enough to just hold it in my mouth?"

While savoring the taste of the penis she had taken into her mouth, not to the point of discomfort, Chika glanced sideways to confirm that the iron bars wouldn’t open, then began to think.

"It says ’savor it’... so I guess I need to lick it and really savor it, not just hold it in my mouth... ♡ ... Hmm, I guess I have no choice, I have no choice... ♡"

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

To open the iron bars.

Making excuses to herself, Chika took the penis further into her mouth and began to gently lick it with her tongue.

"Hmm, it might be bitter...♡ The taste of your dick is spreading in my mouth...♡ I don’t know... I’ve never really savored a dick this much before, so it’s kind of refreshing...♡"

"Mmm, mmm...♡ Mmm, mmm, mmm...♡"

Each lick of the penis spread the flavor throughout Chika’s mouth.

When she was raped, she was forced to take it in her mouth and was subjected to violent movements.

Chika was getting a little excited about this unprecedented opportunity to savor it at her own pace.

"Mmm, mmm...♡ Mmm, mmm...!♡ Mmm, mmm..."

"Ah... Your dick is getting hard...♡ Mmm... Since it’s come this far, I might as well suck and lick it until you cum...♡"

Perhaps caught up in Chika’s excitement, or perhaps it was because she kept licking it.

The soft penis gradually hardened and became erect.

Chika was excited by this and began licking his penis.

"Mmm, mm, mm...♡ Mmm, mm...♡ Mmm, mm... mm, mmm...!♡"

"Lick both the front and the back... Lick the base and the tip... Mmm, I’m licking it in a really naughty way... ♡"

"Mmm... Ah, my dick is twitching... Ah, I’m cumming...! ♡"

Not just holding it in her mouth, she licked his penis as if tracing it with her tongue, licking the penis from the base to the tip as it protruded from the hole. 𝒻𝘳𝘦𝘦𝘸ℯ𝒷𝘯𝘰𝑣ℯ𝑙.𝘤𝑜𝘮

Chika licked and savored it as if she were performing a service.

The licking seemed to have pushed his penis to its limits, and it trembled violently before... ejaculating.

"Mmm, yes... mm, haaa... ♡... Ah, the iron bars opened... I should have just licked until I ejaculated."

She took the semen that was squirted on her firmly into her mouth.

She drank it slowly, spilling some as she went... and just as he finished ejaculating, the iron bars slammed open, allowing her to proceed to the next passage.

Therefore, Chika slowly stood up, clutched her chest tightly with both hands again and started walking.

"I wonder what’s next... Oh wait, there’s already another room..."

The corridor was about ten meters long, and the next room was already in sight.

Therefore, Chika quickly went into the next room.

"Um... what do we do here...?"

The room was rectangular in shape.

A corridor with iron bars lowered against the wall in front.

Up to this point, it was exactly the same as before, but the difference was that there was only one hole in the wall on the right side before.

In this room, there were some on both the left and right sides.

There were many of them; on each side there were 40 holes arranged in a grid of 5 vertically and 8 horizontally, for a total of 80 holes.

Chika had checked everything up to that point and stepped into the room...and then.

The passageway through which Chika had entered was also blocked by iron bars, preventing anyone from going in or out.

"Huh...!? The hallway... Ah, ahh!? ♡ My, my penis...!?"

Chika was surprised when it slammed shut.

Following that, eighty penises simultaneously sprang out from the eighty holes in the left and right walls.

As Chika blushed in surprise, a piece of paper fell from the ceiling of the room.

[Find the cock you just learned about and make me ejaculate again!]

"Huh... I have to find the same dick as the one from earlier in here...? ...Wait, the wall is moving... Huh, what...?!"

Chika was surprised by what was written on the paper.

The wall from which the penis was sticking out began to shake with a clunk.

Upon closer inspection, it was slowly moving toward the center of the room.

The room itself seemed to be starting to feel cramped.

"I-I’m gonna get stuck between those dicks sticking out of the wall...!? ♡ I-I have to find them somehow...! ♡"

That meant, if it continued to narrow completely like this, you’d be crushed by the massive number of penises sticking out of the wall.

Did she see that future?

Chika, though feeling a little excited, first approached the end of the penis.
