Cage of Tentacles / 苗床快楽地獄の触手監獄～

After finishing her business in the city, Yuria was walking along the small path in the woods leading to her house.

Suddenly a loud shudder shook the air, and a hole in the ground opened beneath her feet, swallowing Yuria whole!

...When she came to her senses, she found herself in an unthinkable situation... She found herself inside an eerie, tentacle-filled cave.
"The seed tentacles," which impregnate humans to increase their numbers, had invaded the area beneath the forest she called home.

To turn the people they trap into docile "seedlings," they ruthlessly train them, rendering them incapable of resisting pleasure.

Will Yuri be able to keep her sanity and escape this maze of tentacles...?!
