From the day the young, voluptuous beauty became my mother—in the four days I gave her an aphrodisiac—she slowly transformed into a wanton woman. (Miyamoto Rui EBWH-235)

My family has always been a man's household. My father's second wife moved in as my stepmother; she was a large-breasted beauty of about my age. Although I began living as her stepmother, I couldn't see her as a mother. Instead, I treated her as an object of my sexual desire, leading a dull and repressed life. Eventually, the constraints of morality were broken, and I started adding aphrodisiacs to everything she ate, gradually turning her into a sexually frustrated and aroused woman. When her endurance reached its limit, and her vaginal fluids overflowed... the lewd, large-breasted beauty transformed into a filthy beast, begging me to hold her.
