Shiori’s lower body was thoroughly assaulted by the "Lustful Shell."

She lost consciousness while being tormented, and when she next woke, she was on a sandy beach.

"Hmm... Ah, this is... Ah, it’s restarting..."

Shiori, who had been laid to rest on a beach chair on the shore, sat up and began to understand what had happened to her.

She quietly got off the beach chair and stretched her body.

"Hehe... being attacked all over my lower body by those slimy tentacles... that was pretty good...♡ Being clamped by the shells felt like I was being eaten. It gave me chills too...♡ Hehe...♡"

"...Phew...Okay, let’s try it one more time for now."

Shiori, with a slight flush on her face, reminisced about the pleasure she felt from being tormented by the "Lustful Shell."

By taking a few light, deep breaths, she shifted her focus.

Once again, she began to move toward the sea.

"...Well, next I’d like to try going to a dungeon..."

In the crystal-clear seawater, Shiori moved forward, swaying back and forth, while looking around at her surroundings.

As she moved slowly, still unfamiliar with the underwater world...

The "Lustful Shell" appeared before Shiori once again.

"Houtaa... Again, taaa...!"

"Ugh... You’re back again. This time, I’ll give you a proper fight...!"

An excited cry came from somewhere, and the "Lustful Shell" extended its wriggling tentacles from the gaps in its tightly closed shell.

Seeing this, Shiori quietly took out her air gun, took aim, and fired.

"What!? Whoa... Whoa, Dad!?"

"Huh...ha...!"

The projectile fired by the air gun didn’t lose any power even in the sea, and it hit the "Lustful Shell" straight on.

The "Lustful Shell" let out a surprised cry at the blow. But instead of falling, it shook its body and tried to charge forward, so Shiori pressed her attack.

It seemed to have hit a vital spot, and with that one blow, the "Lustful Shell" fell.

"Okay... it works fine even underwater."

While watching the Lustful Shell disappear smoothly, Shiori nodded in approval at how the air gun felt to use, then started moving forward again.

She proceeded through the sea for several hundred meters, defeating the "Lustful Shells" that occasionally appeared along the way.

The depth of the sea now exceeded 100 meters, and Shiori was moving by swimming rather than walking along the seabed when something submerged beneath the ocean came into her field of vision.

"That’s... a dungeon..."

It appeared to be a large sightseeing boat, approximately 100 meters in length.

It had probably been a very fine sightseeing boat originally, but currently, the ship’s deck was being crushed by a large, round, rock-like object.

Besides that, there was a large hole in its side, and the ship was damaged in many other places, making it a truly gruesome sight.

Its name was displayed as "The Sunken Tourist Ship."

"...Since we’ve gone to the trouble of finding it, let’s go in."

As it was the first dungeon discovered underwater, Shiori said this and plunged into the ship through a large hole in its side.

"The inside is completely filled with seawater."

"Well, that’s to be expected, I suppose... Anyway... Shall we begin our exploration now?"

Because it was submerged at the bottom of the sea, the inside of the ship was filled with seawater.

Shiori checked the area while treading water, then began to move toward the front of the boat.

"...That is..."

And then, shortly after she started moving forward...

A monster appeared before Shiori.

"Oct..."

"...Octopus?"

What appeared was an octopus about 20 centimeters long.

Floating gently in the seawater, with its round head, eight legs, and red body, it looked like an ordinary octopus. But above its head was the text "Small Octopus Lv34."

Upon determining it was a monster, Shiori quietly raised her air gun.

"Let’s find out what kind of monster it is for now...!"

"Arrow, to the ball!"

It was a warning shot intended to draw aggro, and there was no intention to hit anything, so the wind bullet that was fired with a bang missed the ’Small Octopus’ and passed right by it.

However, it seemed to react to the attack. When the "Small Octopus" let out a cry, it suddenly changed its swaying motion from before and charged toward Shiori with great force.

"Kya...!? Wh-what are you sticking to...!? Ah, ah, ah...!? ♡"

Topa, Octopa

The charge landed on Shiori’s right breast.

The "Small Octopus" skillfully manipulated its eight legs to shift the bikini covering Shiori’s chest, then latched onto her bare breast and began sucking on it with the suction cups on its legs and the mouth on its body.

"Ah, mmm! ♡ Ah, ahh, hah, mmm...! ♡"

"W-wait... just wait... ah, ahn, ah, aah! ♡"

"Th-this... is... quite... intense...! ♡"

"Topa, topa! Octopa!"

While having her breast massaged by eight legs, her breast was being kneaded with suction cups and then sucked.

Her nipple was also being played with in its mouth.

With the focus solely on her right breast, Shiori was at its mercy, and she quickly began to let out sweet moans, starting to feel pleasure.

"Octo, Top! Top! Octopaaaa!"

"Ah, mm! ♡ Ah, ahh! ♡ Aaah, ahh, mmm! ♡"

"Rubbed, sucked, played with, rubbed, sucked, played with."

Shiori let out a sweet cry, her body trembling, and swayed as if drifting in the ocean.

"Octo... Octo, Topa! Topa!"

"Ah, ahh! ♡ Ahh, ah, aaah! ♡ Mmm, haaah, ah, aaaah!! ♡"

"I-I can’t take it anymore...! ♡ Any more than this... I-I’m going to cum...! ♡"

Then, faced with the intense sensation of having her nipple bitten hard by the mouth of the ’Small Octopus,’ Shiori came right then and there.

"Topa, topa... Octopa..."

"Mmm, ahh...♡ Ah, ahh...♡ Haaah, haaa...♡"

After Shiori came, the "Small Octopus" let out a satisfied cry and then detached itself from her chest.

However, it seemed he still intended to torment and savor Shiori’s body, as his legs swayed, and he appeared to be carefully considering where to place his next thrust.

Seeing this, Shiori gripped the air gun tightly, which she had almost dropped while she was feeling the effects, and instantly aimed and fired.

"Topa!? Topa, aaah..."

"Hmm... Mmm, haaa...♡ Haaa...♡ Haa, haaa..."

The wind projectile, fired unexpectedly, was not dodged by the Small Octopus and hit it directly in the body.

And it seemed that the single blow had finished it off, as the ’Small Octopus’ simply disappeared.

Watching the figure disappear, Shiori took a deep breath to calm her agitated body, then readjusted her bikini, which had shifted out of place.

"Phew... That was quite a good torment... ♡ As expected of an octopus... ♡"

"Hehe... Let’s keep going... ♡"

As she said this, her face flushed, acknowledging the accusations she’d just received from the "Small Octopus," Shiori began to move through the ship once again.
