The source of the lewd gaze I've felt for some time turned out to be someone unexpectedly close. A lustful monster lurking within the house demands sexual service from the lovely stepsister. Though reluctant, she obediently submits—a pitiful sex doll. Meanwhile, the lustful stepmother constantly tempts her stepson, eyeing his young, vigorous cock once again today. This house has become a cage where sex beasts writhe and thrive.
