This is the first in a series of first-time shots of middle-aged women from the popular Obasan label series "First-time Shots of Middle-aged Women Documentary." "After I turned 40, my libido just kept growing..." says Kaoruko, who, contrary to her quiet appearance, has an insatiable Kokoro for erotic things. Her words are no lie, and even during her first sex shoot, she forgot about the camera and kept climaxing. A three-part documentary where "shyness" and "climax" are all mixed up!
