Shirakawa Kiyoki, with a beauty that belies her 41 years, is also a mother of two in real life. This time, she engages with an extraordinarily virile younger man, reminiscent of her son, as she explores her "maternal instincts." While saying, "You're cute," she allows him to suckle at her breasts in a nursing play, gently enveloping his erect penis within her vagina. Despite the resemblance to her son, her reason crumbles as she is overwhelmed by the virile man's penis.
