Our protagonist, Chise is a student in a magic academy.
She visits a rural area with a cave accompanied by her elder brother
(can be renamed) for her graduation examination.
"It's gonna be a piece of cake because you've already graduated and I've got good grades!"
She thinks nothing difficult would happen in the examination, but...!!
The too brother-loving little sister and the salacious sister-loving
elder brother's slightly risque adventure begins.
At the beginning of the story, there are two choices which lead to two different scenarios:
- Route 1: The little sister gets in heat and becomes lewd
- Route 2: You suppress the little sister's estrus
(Conversations and H scenes differ between the two routes)
