A newlywed middle-aged couple declares they will conceive a child and films creampie sex for 300 days. To maximize pregnancy chances, they focus on repeated creampie sessions during the woman's ovulation day each month. On other days, sex is prohibited to ensure sperm potency, causing both partners to build up sexual tension, resulting in long, intense sessions. The film captures the couple's passionate, obsessive intimacy in explicit detail. After nearly a year, the story reaches its climax as they take a pregnancy test to discover the result.
