Three attractive Tokyo wives discover that happy marriages are far less simple than they imagined. Lies, betrayal, debt, infidelity, and sexual incompatibility push them toward men outside their marriages. Hikari Ikuta, 26, has lost interest in her indifferent husband and lies about traveling to Tokyo, only for her plan to drown in pleasure to go awry. Misaki Sakurai, 28, cannot return to ordinary life after learning that her teacher husband had an improper relationship with an adult student. Erina Oguri, 26, is exposed as the other woman and forced to choose between paying compensation or quitting her job and leaving Tokyo. Wanting to be seen, touched, and satisfied as women, the frustrated wives transform behind closed doors and show the bold, filthy sex their husbands never knew—291 minutes with seven ejaculations.
