Men who are forced to wear chastity belts have their ejaculation strictly controlled, enduring months without sexual release, driven to a state where even masturbation and erection become nearly impossible. As semen accumulates with no outlet, they tremble in agony. Gyaru girls in bikinis and lingerie taunt the masochistic men, rubbing their bodies against them and giving blowjobs over the chastity devices. They press their genitals against the restrained penises, mockingly laughing, "Can't get inside, can you?" while mischievously teasing them with electric vibrators, repeatedly tormenting the men. Treating the men like sex toys, the girls satisfy themselves by making them perform cunnilingus and showing off orgasms induced by vibrators. Amid the cunning cruelty of the girls and the suffering of the male masochists, a dynamic of domination and submission unfolds.
