【P:P】I want to go out with Onii-chan.

It’s an incestuous relationship between a brother and sister who become increasingly addicted to each other after a kiss.
This is the second in a series. It’s a story about a little sister who goes to stay in her brother’s room during the summer vacation without telling her parents, and of course nothing happens. It’s a continuation of the story, but I think you’ll enjoy this book alone. It’s 32 pages including the cover.
