Soooooo I finally managed to get my hands on this book. It's quote noticeable that the book is from ancient times of hand drawn Chinese porn books, but its main theme is still up to date and relevant to our interests ( ͡° ͜ʖ ͡°).

It feel nice finding this because this is the only work from this artist that have been uploaded here. Synposis: Sakura use chloroform on Rin, tied her in dungeon, kisses her with drug and bring SHirou to threesome.
