I can't see anything yet this was very arousing is this what they mean by new fetish unlocked? Is this even a fetish or is my mind just running wild imagining the plapping going on under there, the grunts, the moans, the hot breath as the exertion makes it damp and sweaty under there?

running around a dungeon
see this
you can hear the erotic moaning and see the movements

do you immediately flee or do you try to rescue whoever is under there being plapped?

I don't know about you but I'm fleeing there's no saving whoever's under there now you can only hope they'll be let go free of harm after it's over
