Four hours of six insatiable masochists climaxing through sadistic sex and relentless hardcore training. The lineup includes an office worker from an eyewear shop in Himeji, Hyogo; a Hokkaido native who moved to Tokyo after junior college and works at a lunch shop; a sex-crazed delivery driver from Kyushu; a busty lunch-shop employee lost in constant fantasies; a wildly perverted sex addict working at a food-processing plant; and a huge-breasted warehouse sorter. All six women finally unleash the submissive cravings they can no longer suppress.
