Haru Yamaguchi is a Japanese/English teacher for college students who have emigrated to the United States. At first she is a very conservative woman, incredibly shy and modest. But in her private life, she is a cock hungry slut who loves to fuck other men for her husband's enjoyment and humiliation.
Haru has had a lot of free time lately, she is a good wife and tries to keep her husband happy even if she is not feeling it. Tired of milking Koji's small penis, she has discovered a new, huge guy who is the father of one of her students. It must be said that there is no comparison possible.
