Hane, a female college student who loves her mother who raised herself more than anyone else. Such a mother suddenly said she wanted to get married again ... The man my mother brought home was very kind. Hane, who was reluctant to talk about remarriage, changed her mind when she saw her mother's happy expression. However, the man "Yasushi Tamura" was a rare rod master and a bad man. A man who brainwashes his mother with SEX with aphrodisiac applied to the cock and sweet words. And when my mother's training was over, I turned poisonous fangs to Hane!
