Adult's Hobby - Little Sister Control Dungeon Ver.1.0 ENG

Machine translate

Contents
Protagonist Mayula is ordered by the top shrine maiden to enter a certain cavern, and recover the Codex of Truth.
However, for this test dungeon that is to be completely alone, Mayula brings along her big brother...

A long RPG about a cheeky shrine maiden and her sexually harassing big brother
escaping an ero trap dungeon.

Recover the Codex that only pure maidens can lay hands on, and escape all 50 floors of the dungeon.
There are no deaths in the game if you are defeated, but you'll lose all your equipment, levels,
and items, and start back at the beginning. However, your memory and skill points carry over.
Take on the dungeon as many times as it takes, and escape the dungeon!

...Of course, if Mayula loses her virginity during the adventure, that will be restored as well...

What happens to the siblings' relationship depends on your actions, and your little sister's self-control!

* Big brother sexually harasses Mayula from the start, but doesn't start from penetration.
* A sexual-harassment command is included.
* Virginity-intact play is possible, but there are no particular bonuses or story for it.
