Her husband is a very kind person and their relationship is good, but she is not satisfied with their nighttime activities, and stress just keeps building up. Furthermore, for some reason, her libido has increased, and she spends her days satisfying herself with the adult toys she used when she was single. Misaki Onozaka Onozaka seems to be a serious person who has never experienced orgasm during sex. She has had experience with several men, but she has never had sex with someone she truly loved. However, for the first time, she found her true love, and she ended up marrying her current husband.
