Seven Days of Sex with Cousin

Seven Days of Sex with Cousin is a manga that explores the intimate relationship between two cousins, Boku and Itoko. The story begins with Natsu no Kagerou, where Boku and Itoko's familial bond is established through their shared summer experiences. This is followed by Kumo no Su Houmon, where the cousins visit each other's homes, deepening their connection. Itoko Shuurai marks a turning point in their relationship, as they develop romantic feelings for each other. Boku to Itoko no Nanokakan Sex is a pivotal chapter, where the cousins spend seven days together, exploring the boundaries of their relationship. Inbou no Elevator is a surreal and licentious chapter, where the cousins' desires are pushed to the limit. Shouwa no Semi, the final chapter, is a poignant reflection on the Showa era, where the cicada's song serves as a metaphor for the passing of time and the cousins' own fleeting youth. Throughout the manga, the author masterfully weaves together themes of family, love, and the blurring of boundaries between reality and fantasy.
