Tsubomi, a virtuous and gentle beautiful wife, loved her husband 'Tetsugaku' and lived a carefree life. However, her husband was busy with work, and the child-making they had planned had become infrequent lately. On the other hand, 'Tsubomi' had reached an age where her sex drive was increasing, and her body had become more sensitive, especially her breasts... her nipples were becoming more sensitive. She would often find herself masturbating with her nipples during breaks from housework. But one day, everything changed when her husband brought a subordinate home.
