After meeting through an arranged marriage, Mako marries her husband Shitara Bonta and loses her virginity on their first night together.
They continue to have sex, but she finds it painful and doesn't see the appeal.

One day, at a drinking party with her coworkers, she drunkenly reveals this fact. From there, Mako's life begins to change drastically...

She gives blowjobs in the bathroom and has sex with male part-timers from work. When the store manager finds out about this, instead of scolding her he eats her out and makes her feel pleasure like never before. She goes along with it all the way to a love hotel where they have sex. Later on, she even 69s while giving paizuri service to her father-in-law in the bathroom of their home. Then still wearing only an apron, she gets fucked doggy-style standing up in the kitchen. After being picked up by a black man she just met at a club, they have sex right then and there without caring that people are around them watching. Finally ending up having sex in the bedroom of their marital home—the nest of love between herself and her husband... While whispering words of love for him into his ear... Her body seeks other men for its own carnal pleasures.
