The protagonist of the hentai, Ichiro Tani, loves hostess bars and spends the lion's share of his salary on them. One day he had so much too much to drink that he spent all the money of the company he worked for on girls. Ichiro decides to run away to the mountains. His car broke down during a heavy snowstorm, and he was forced to walk blindly and look for help. He soon found salvation at the Ishikan inn. There Ichiro met the widowed landlady Ruri Munakata, her daughter Nakoto, and the lovely maid Ren. No one else... His passion was ignited at the sight of the luscious bodies and pretty faces of the residents of this house, but fearing that they might call the police if he molested them, Ichiro decided to refrain. Later, over dinner, Nakoto was rather rude to him, and as an apology, her mother offered him the chance to be her tutor until spring, respectively with a stay in the house, which Ichiro saw no reason to refuse. The first night, lying on his bed and thinking about the events he had done and which later brought him here, he noticed the landlady of this house sneaking into his room, at night, alone, into the bedroom of a healthy man, no way that at her age she would not know what she was doing. Indeed, no sooner had Ichiro realized what was going on than it came to passionate sex, after which Ruri made him a tempting proposal, if he wants more, he first needs to take her daughter's virginity, for in the mountains a good man is rare, and the mother is worried about the girl, because she is already at that age, but still has not yet known male caresses. Well, once the approval is received from the mother herself, then it is a small matter, though he did not fully believe her, but was under her spell and accepted the proposal. And so the next day Ichiro's work as a tutor began. Nakoto was a difficult student, but she had no ill will toward her teacher. And because he had permission from Ruri, and his male hormones were increasingly making themselves felt, Ichiro couldn't take it anymore and pushed Nakoto onto the bed, but lifted her skirt and found her wearing a chastity belt. Nakoto smirked and told him that she would give him her chastity, but only on one condition, if he impregnates her mother. What on earth is going on in this house! A mother who wants him to have sex with her daughter... The daughter who wants him to impregnate her mother... And the maid who serves them both... The story of debauchery begins!!!
