A story about a big sister trying to seduce her younger brother.

The protagonist is feeling troubled lately.

The reason is his older sister who's got an air of childlike innocence around her, she is always trying to engage in seemingly innocent but also intimate physical contact with him whenever possible. She even does things like: when he enters the bath, she'll tell him "Let's take a bath together!" or when she sees that he's got some cream on his cheek, she'll say "There's some cream here." before licking it off his face. He can't help but feel like the extent of her skinship is increasing day by day.

Even today, the protagonist was watching TV in the living room when his older sister approaches him, fresh out of the bath and wearing only a bath towel. He's very nervous about his sister's almost completely unguarded and sexy body, and with a suggestive, amorous look on her face she says something unbelievable: "You can touch if you want." That night, the protagonist gets horny by himself, thinking of his older sister while lying on his bed. He remembers all of his sister's actions up until now and while going through such memories, he finds himself knocking at the door to her room.

"You finally came." says his sister, as they approach each other...
