Follow the tunnel.

Once again, the path slowly narrows. The two of you are nearly touching the walls with your shoulders. Much to your surprise, after a short distance, you feel a hand take hold of yours. You glance back, and she does her best to avoid your gaze as the both of you continue. Eventually, she does break the silence, as if the tension of her nerves were too much to bare.

"It's to... make sure we don't separate," she says.

"Good idea," you reply, squeezing her hand more firmly.

She eeps.

After a wide turn, the tunnel enters a much wider one. This time, it's far more rounded along the edges, and it seems to go straight in opposite directions, as if you just exited a side path to enter the main route. The downside is you still don't know which way to go, though at least there's more room now, and it doesn't look quite like this would have been crafted by water alone. Perhaps this is an actual, man-made tunnel, and you're on the right track.

"Left?" you ask. She nods.

Continuing to hold hands, you make your way down the wide tunnel, briefly glancing back into the dark abyss of the opposite direction. Glowing mushrooms only do so much when a pathway is this long. It's flatter here though, and easier to walk. It's starting to get chillier though, which would be far less of an issue if you won't both nude.

"Your grip feels nervous."

"W-Well, of course I am. Are you not? You're naked too."

"On the bright side, I'm not erect anymore."

She looks down to see your member now swinging between your legs. It isn't standing straight up anymore, though she seems just as distracted. Finally, to snap herself out of it, she asks, "Where do you think we are?"

"If I had to guess," you respond. "I'd say some sort of deep sea network of caves, and we were brought here by Seno'nojoch. Gwyn was tasked to sinking the island into the ocean after all. But I guess her patron showed up far sooner than even she expected. It didn't look like she was too pleased about what was happening either."

"Making deals with such dangerous beings is so reckless."

"She's pretty strong on her own, but I guess some people endlessly seek more power."

"Do you?"

"Hmm. I mean, enough to protect myself and the others. The only thing I really seek is a life of happiness. Of comfort. To live with those I love, without risk of being killed by some sort of maniac. We defeated Elok Daven, but it always feels like there's something else--"

Your eyes widen. Something is coming.

Quickly, you grab Anastasia by the sides, and hurl the both of you into a concave opening in the wall nearby. There the two of you squeeze together--naked bodies intertwined with little room to move, and no desire to given the sound that's coming. You feel her heart racing, and her both breaths against your neck. Her body is soft and warm. Then a rumbling sound grows and grows until you glance to the side to spot countless legs. The massive head of an eel barely fits through the tunnel, and while the body looks like one as well, it has limbs like a centipede. It runs by like a train. Then after a long, tense moment, the lengthy creature finally passes, and the sound fades into the distance.

Anastasia remains in your embrace for a time after. Her nostrils flare. She shivers. Slowly, she looks up at you.

"Don't be scared," you say. "It's gone now."

It isn't fear you sense from her. She's surprisingly brave in terms of facing great threats. What causes her heart to race is something else.

She pulls away, wrapping her hands around her body. The one between her legs acts especially strange. "Th-Thank you," she whispers. "You have keen senses."

"Thanks. I got it from sleeping with the creator deity of the catfolk race."

"... I'm sorry?"

"Let's go. If we keep down this way, at least we know whatever-the-fuck-that-was went the other way." You offer your hand once more.

After swallowing hard, she takes hold of it, and follows partway behind you. Of course she can't cover herself all that effectively while doing this, so she opts to conceal only her pussy, allowing her perky chest to bounce freely beside you. Somehow you've managed to not get hard again, which is impressive given the circumstances.

You stare ahead. "It looks like there's another branch out of this tunnel up there. Let's take a look."
