## Description
One day, the protagonist who lives alone was visited by his younger sister, Hana. She came to ask him to help her study, but then she suddenly took off her clothes.

Unbeknownst to her, the protagonist got aroused when he saw her body, as she's the type of girl he likes. She also said, "I've been naked at home lately. It feels good, so please try it with me." Then proceeded to undress him and was surprised by his erect genital.

He couldn't tell his sister that it was because he's lustful. The protagonist told her that there is milk in there to make her smarter. She immediately grabbed the protagonist's rod and said, "I wanna drink Onii-chan's milk."

And so begins the lives of the protagonist and his idiot but cute little sister.

An average college student.

Currently living alone in order to attend college. He doesn't have a girlfriend. ...Or rather, he's a siscon who just loves his little sister very, very much. Yet he cannot meet her, and even if he did, he's not sure if he could realize his love for her.

Then, not only does his sister suddenly appeared, but he also has to live together with her. His emotions and rational mind are easily thrown off the rails.

### Mitsui Hana (御津井 芭華)
The protagonist's younger sister.

With the birth of their long-awaited daughter, the sibling parents' flower garden was in full bloom, and they elaborately named her after it. However, it was only after the birth certificate was submitted that they realized that the phonetic pronunciation of the name was "Baka", as in "Stupid".

She's innocent and very positive, but perhaps because of her name, she's also an idiot who doesn't think about anything, prancing around completely naked at home with no sense of shame in her bones. She has no sexual knowledge whatsoever, but gradually learns to take pleasure in the act of "studying" with her older brother, the protagonist.

She is glad that there is something that she can do, even though she is an idiot, and begins to actively seek out the deeds.

"Wow! Onii-chan can produce milk from his penis!"
