Men are fitted with locked chastity belts that they cannot remove, forbidden from ejaculating for an entire month—an extreme condition. Rina Uchimura then uses erotic techniques to forcefully release the built-up semen stored in their testicles. Inevitable explosive and massive ejaculations follow, delivering pleasure so intense it feels liberating to both mind and body just to watch. A highly satisfying erotic work dedicated to male masochists, featuring aggressive female domination, handjob, and masturbation themes.
