Shinyuu no Imouto ga Kannou Shousetsu no Model ni Natte Kurerurashii

Ryutaro Kanae is a high school boy who writes erotic novels using his best friend's younger sister, Suzune Minashizuki, as a model. One day, Suzune finds out about Ryutaro's novels on the Internet, and she asks him, "I am the model for your novel characters, aren't I ......?"

When Ryutaro apologized for using her as a character without her permission, Suzune rolled up the hem of her skirt and said, "If it will help you, you can look at me in sexy ways......" She suggested a number of perverted situations, such as studying JK's bare feet, reading an erotic novel out loud, and dom-sub play.

The beginning of a super kinky love comedy with my best friend's JK sister.
