Serino, a 31-year-old housewife, has been married for five years. As she enters her sixth year, she's starting to realize the gap between her ideals and reality.

The sensitive, fair-skinned body nurtured by the northern land responds excessively to extreme demands, repeatedly climaxing with two cocks at once.
