The man whose wife passed away decides to discipline his daughter Kanon into becoming a mature woman on her own. He forces her to masturbate and records her intense orgasms as a growth record. He trains her in fellatio and even teaches her irrumatio, which he had been doing since her school days. As she grows up and brings a boyfriend home, the man becomes enraged and restrains her, subjecting her to toy torture. He then delivers a brutal punishment with a choking sex session.
