Furinzuma: Hitoyo no kairaku

Hiroshi and Noriko are a married couple who both work. Hiroshi travels frequently for work, and Noriko is busy with her accounting job, so they have little time for conversation or intimacy. The day before a business trip, Hiroshi hits it off with a refined married woman named Yoshie whom he met by chance, and they end up going to a hotel together. After sex, they call a call girl and spend a wild time in a passionate threesome...
