22-year-old I-cup beauty Yu Sasamoto (pseudonym), who is getting married in six months, is back again. Her fiancé is away on a business trip, so she goes on a two-day trip with a man from the city hall who she got along well with in a previous shoot. "Should I get married like this...?" Away from her mundane daily life, she indulges in open-minded sex in the car, in the hotel room, in the open-air bath, and more.
