The mother-in-law secretly had incest in her youth with her son-in-law who had just taken aphrodisiacs

His father has remarried and his new mother is only 4 years older than Hajime. In his new life with his young mother-in-law Saki, Hajime always covets her beautiful big breasts and youthful body. Hajime, who was studying pharmacy at the university, mixed what he had and secretly gave it to Saki as an aphrodisiac. After a few days, changes appeared in Saki's body. I'm dying to have the body of a young mother-in-law … I sucked Saki every day, who turned into a gangimari horny woman with aphrodisiacs.
