The fate of a busty girl is a sad one. Bullied by boys in her youth, in middle school, every guy who approached her was only interested in her body. As a result, she lost trust in men and ended up marrying a man she thought she could trust, only to find herself in a sexless marriage, burdened with her impressive breasts, suffering from back pain and sexual frustration as she aged. Hinako is lucky, you could say. Thanks to her husband's perversion, she gets to be used as a sex toy to such an extent.
