Two ordinary women are trained to become depraved female masochists, documented in a realistic format. The first is a 29-year-old who claims to be an event companion. When three fingers are inserted into her anus, she writhes and honestly exclaims, "It feels strange," captured in vivid detail. The second is a 19-year-old glasses-wearing girl from Shikoku. Despite saying, "The entrance hurts but it's okay deeper inside," her enthusiasm grows steadily, revealing her natural responsiveness. Their honest willingness to embrace such unconventional experiences is undeniably captivating.
