Incontinence Experiment Club No. 1 Who's the JAV actress in this video? Amateur? Name revealed!

A work documenting humiliating experiments involving involuntary urination, bedwetting, enemas, and diapers. The "Incontinence Experiment" closely observes the way liquids leak and soil the subject's body. The first segment features incontinence while standing upright, the second while legs are spread apart, the third examines how the buttocks become wet, and the fourth analyzes the spread of urine. The subject is Sayuri, 21 years old. Additionally, the "Controlled Infantile Regression Experiment" explores whether adult women regress into infantile states through bedwetting and diaper use. The subject is Aiko, 28 years old. A shocking series of experiments blending humiliation and physical transformation.
