Mizuno Asahi is bored with her marriage, and especially with her workaholic husband five years her senior. The life of a Japanese housewife is lonely and dull, and the need for an escape can tempt even the most faithful of wives.
Asahi is intrigued when a pair of handsome young foreigners move into the same building, even more so when they both take an interest in her. The summer heat and the risky thrill of a forbidden interracial encounter awakens a powerful urge she simply has to satisfy.
This is Asahi's first experience with foreign men and their outsized endowments, and juggling two simultaneous affairs only adds to the excitement. Neither of her exotic White boy-toys knows about the other, and her husband is clueless about both of them.
Or is he? When her husband starts to notice things amiss, Asahi realizes how dangerously close to destroying her marriage she has come. By the time her two foreign lovers have moved on, the seed they left behind has already borne fruit. What will she do if the baby is mixed-race? How will she explain it to her husband? Could he still be the father?
