Kamakiri is one of the best works in the genre I have had a pleasure to read so far. It deals with a relationship between two cousins and it combines it with psychological elements, and it does so superbly. Usa has a strange phobia - he cannot stand when someone touches his neck. The story explores the complex relationship between phobias and fetishes and the fine line between them. It also shows how dangerous a relationship can get if you lose yourself in physical games. Kamakiri offers a sexy, complex story of a somewhat disturbed relationship, and that makes it truly special.
