After a month of living as her master's slave pet, 33-year-old Yurina now spends every evening servicing his desires until bedtime. As he loses interest in her pussy, he begins training her anus instead, while also using her throat and vagina without restraint. By day she is a successful spatial designer with a comfortable life; in private, she seeks the beauty of suffering and wants to perfect her existence as a degraded masochistic pet.
