Tajii, an only child raised in a single-mother household, secretly harbored romantic feelings for his mother Ryoko. However, when talk of remarriage surfaced, he began to harbor hatred towards the potential partner. He thought, 'If my mother is going to belong to someone else, I might as well make her my slave...' Driven by his desires, Tajii tied up Ryoko, shaved her pubic hair, and raped her. With photographs taken and no choice but to obey, Ryoko faces even more humiliating training... The debut pubic hair removal work of popular mature actress Murakami Ryoko.
