[SSIS-699] On the seventh day of continuing to give aphrodisiacs to my busty mother-in-law, who is four years older, I fell into estrus who wanted incestuous sex many times. Saki Okuda

His father remarried and his new mother was only four years older than Hajime. Hajime was always lusting after a new life with his young mother-in-law, Saki, with beautiful big breasts and a still youthful body. Hajime, who attends the university's Faculty of Pharmacy, concocts the ● things he obtains and secretly administers them to Saki as an aphrodisiac. After a few days, a change appeared in Saki's body ... I want the body of a young mother-in-law ... I munched on Saki every day, who turned into a gangimari nymphomaniac with an aphrodisiac.
