Housekeeper Reiko is actually a government-deployed stepmother-type android. To heal the emotionally broken father, she comforts his heart and cock with intense blowjobs and hip-swaying cowgirl sex, while flashing her panties to seduce the son and arouse his young cock. She persistently tries to heal the father's psyche by teasing him with masturbation scenes. However, the son, who has fallen for Reiko, discovers her true identity. Before the government finds out, Reiko begs the son for one final creampie sex. The two passionately take each other, climaxing with deep vaginal ejaculation.
