Nine years into her marriage and a mother, Rena Fukii approached us with a request to appear in an AV. She has never forgotten the tight-bondage training sex she once had with a former lover, and has long desired to experience it again. Visiting her home during the daytime while her family is away, we captured a 170-minute bondage documentary in which she exposes her secret desires—hidden even from her husband—and undergoes intense, thorough training. This shocking work realistically portrays the depraved ecstasy of a busty married woman as she is tied up, insulted, tormented, and violated, delivering raw creampie sex in explicit detail.
