HBAD-425 Ayano Kato, a mother forced to have sex with her son's friend's brat

A friend (bad kid) of an only son from a single-mother family is coming to stay with me during summer vacation. Her mother, who looked down on her as a child, fell into the trap of the brats... and before she knew it, she had accepted the sexual treatment of the brats... Ever since her husband died, her mother's frustration, which she had almost forgotten, exploded and she even ended up taking care of her own son...
