Serino is a 31-year-old housewife. She's been married for five years, and she's starting to understand the gap between her ideal and reality. (Was this really the happiness she wanted in life?) As her husband comes home late and she misses her more and more, the number of times she masturbates increases. And then she finally tries out a dating app... Her sensitive, fair-skinned body, born in the northern lands, responds excessively to the extreme demands of two cocks at the same time, repeatedly climaxing.
