A long, long time ago in the elven village, a book descended from the sky. The detailed accounts of elves who went out of the village are illustrated in it. For the elves who dwelt deep in the forest, this was an extremely terrifying discovery. Horrified by what they saw in the book, the elves erected a barrier to cut all ties from the outside world. However, there will always be eccentrics among the elves.

When Tatsuo was trying to have sex with Succun in the real world after doing so in the dream world, a beautiful woman with long hair appears before them. Succun is terrified to see her because she is the Demon King who came to take her away. Then the Demon King makes Tatsuo have many orgasms using her body.

In order to defeat the Demon King, the goddess uses her pussy to sexually train Tatsuo even if it means going crazy with pleasure.

The Demon King, after seeing how the goddess and Tatsuo fucked, asks Succun to transform into the hero to have sex with her.
