The highly anticipated fifth installment of the popular series has finally arrived! Four couples with cuckolding fantasies take on a daring challenge that's impossible to look away from. If they correctly identify the husband's penis from ten options, they win one million yen, but failure means an immediate penalty game with a large penis. The development where the confused wives perform oral sex on unknown penises, turning on their erotic switch and getting wet with excitement, is absolutely thrilling! The cast includes Kurozaki Hana, Kamimura Satsuki, Hazuki Mayu, and Kobato Ruri, each delivering unique performances. The no-hand blowjob scenes are particularly sexy, making it hard to look away. Amid the couples' inner conflict and arousal, the penalty game's immediate insertion with a large penis is full of impact, gripping the audience's hearts. The overall pace is smooth, with a structure that keeps viewers engaged. As a fan, I'm thoroughly satisfied with the intense developments in this work and can't wait for the next one!
