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.

The hero encounters a dwarf craftswoman who makes sex toys, claiming they’re more pleasurable than a real penis. Determined to prove otherwise, the hero initiates sex to show her the true pleasure of a real penis, using a combination of toys and real sex to convince her. The captain of the knights, proud and beautiful, has a secret: she masturbates naked outdoors. In her routine, she finds what seems to be a real penis and decides to use it, experiencing immense pleasure. However, one day she encounters a naked man in the same spot, unexpectedly changing the situation.

The hero, reborn in another world with the “perfect penis,” is defeated by a beautiful Demon Queen. Swearing revenge, he prepares with a diverse group that includes a voluptuous priestess, a tsundere elf, a knight captain who tests erotic tools, a dwarven craftsman, and a loving goddess, all aiding him in his epic revenge. A hero with an infinite sexual desire faces a tribe of bunny girls who attack men to satisfy their insatiable sexual appetite. When surrounded by these bunny girls, the hero creates an endless sex paradise. The leader of the group, Mimi, appears to be a virgin, but her virginity is about to be taken by the hero.
