Laid-back 21-year-old Risa turns out to be so shy that even peeing makes her blush. Nervous under a female director's gaze, she pushes out a glossy, dark stool; on day two, she produces an impressively soft, brick-colored one. Though initially puzzled that anyone could be aroused by scat, she gradually discovers her own way to enjoy the experience. Gentle and considerate, she voluntarily cleans everything up each time.
