Waka witnesses her only family, her brother Kenichi, being bullied at the waste disposal company where he works. The workers pin her down and pin her down, pinning her down and pinning her down. Since then, she has been subjected to intense blowjobs and electric massager torture every day, and even the yakuza from the company's upper echelons show up... Waka loses her sense of self and becomes a sex slave.
