Being a busty woman has brought Hinako plenty of misery: boys mocked her as a child, while men in junior high and high school only pursued her for her body. After losing faith in men, she finally married someone she trusted—only to end up in a sexless marriage, carrying around her magnificent heavy breasts while struggling with stiff shoulders, frustration, and the thought of growing old unsatisfied. Hinako may actually be one of the lucky ones: her kinky husband is happy to lend her out and let her be used as a human sex toy.
