As Ai's fertile window approached, raising the chances of pregnancy, her ordinary life took a sudden turn. A sinister letter arrived addressed to her, reading "Congratulations on your pregnancy," and moments later, a masked man appeared and attacked. He overpowered her body, ruthlessly thrusting his thick cock deep into her vagina and flooding her womb with a massive load of semen. Unaware, Ai was being filmed by hidden cameras monitoring her every move, and gradually her body began responding to the forced ejaculations. Eventually, Ai found herself pregnant with an unknown man's child, plunging her into an unsettling and twisted fate.
