In this 'EX' special, the protagonist becomes the target of a 'punishment game' played by his bratty sister and her two uniquely gifted friends. The theme focuses on 'Body Variety' and 'Reverse Seduction.' Experience the raw intensity as the flat-chested Satsuki Kamimura, the glasses-wearing big-booty Nana Kisaki, and the busty Mina Fukuhara take turns dominating him. This JAV highlights 'Harem Fantasies,' 'Extreme Body Contrasts,' and 'Group Submission,' ending in massive 'Creampie' (Nakadashi) finishes for all three in high definition.
