A newlywed couple in their late 30s decides they want to conceive a child. To increase their chances of pregnancy, they agree to have creampie sex only once a month—strictly on the wife's ovulation day. All other sexual activity is forbidden, causing both partners to accumulate intense sexual desire that they unleash passionately on that single day. Their encounters are prolonged, sensual, and deeply erotic. After nearly a year of this routine, the wife takes a pregnancy test in the bathroom—and sees a positive result. This film portrays the culmination of the couple's love, longing, and perseverance.
