Chinami, 30, is a cool beauty with a model-like figure, stunning legs, and flawless pale skin who works at an upscale department store. Her easygoing husband once accepted that she wanted time for herself before having children, but after entering his thirties he began talking about starting a family. Anxious that motherhood will end her remaining freedom, Chinami decides to fill that limited time with pleasure, losing herself in sex with another man.
