This work is the fourth installment of a popular series that faithfully recreates real erotic experiences of women, featuring skilled pink film actresses, AV idols, and amateur women who love sex. This time, it realistically and vividly portrays stories of incestuous abuse and sexual relationships between mothers and sons, grandmothers and grandsons, set against the backdrop of impoverished families struggling with debt from the late Heisei to early Reiwa era. Set in rural areas plagued by poverty and financial hardship, the story weaves together three brutal tales of sexual abuse involving corrupt bankers, ruthless loan sharks, and depraved perverted teachers, drawing in mothers and sons, grandmothers and NEET grandsons, and a beautiful mother and her son caught in overwhelming debt. Reflecting the social context of poverty, inequality, disasters, and war symbolized by the year "Reiwa 7," this masterpiece for adults blends dark humor into its tragic narrative, evoking laughter, courage, and arousal.
