A newly married couple, Aya, has just moved into a government-run "Declining Birthrate Countermeasures Apartment". Aya is assigned a job called "Artificial Insemination Committee Member". Her duties involve recording the residents' libido and penis condition, then servicing them (having sex) to receive fresh semen through creampie. Refusal means immediate eviction from the apartment and being labeled as against population control measures, leading to various consequences for her future life... Aya reluctantly accepts the job. Will she be able to complete her duties successfully?
