Ayumi is a beautiful and diligent office lady, but due to her clumsy work performance, she gets demoted. Just as she's struggling, a new opportunity arises—handling sales for a major client. However, this is no ordinary business assignment; it's a trap set by the predatory Rinma, who seek her body. In a dark, overgrown ruin, her clothes are torn off and she's forcefully guided into oral sex. From deep inside her vagina to her clitoris, she undergoes relentless training. Depicted in humiliating positions, she screams and gasps as destructive acts are forced upon her. Her body writhes in intense, overwhelming orgasms as she endures the torment. Finally, she's violently penetrated and filled with cum, her face completely covered in semen. What fate awaits her now?
