Meguri is living happily with her beloved husband. Her husband always loves and cares for her, so Meguri has a very happy life. But lately she always feels like someone is peeping at her, and the photo hanging in the house suddenly disappears. Especially when the door lock is broken and you call a technician to fix it, you run out of parts and it takes a week to fix it. That made Meguri feel extremely worried and insecure. And what she feared the most happened, on the day of ovulation, because she forgot to close the door so she hurried back. Suddenly a masked man attacked Meguri from behind. Her strength could not resist him, so Meguri could only beg in despair, watching him "invade" her beautiful, plump body, ejaculating deep inside her uterus! This guy also took pictures of the two people making love and threatened to post it online if Meguri revealed it. Every day she was worried about that man ejaculating into her uterus. Fortunately, Meguri's menstruation was still regular, and she felt a little more secure. Since that time, a month has passed but that name has not appeared again. Just when Meguri was trying to forget everything, that masked man appeared again, on the day of her ovulation. He continued to fuck her, ejaculating all over her uterus and then leaving again. And so, once a month, he appeared and impregnated her. Meguri always wondered who this mysterious man who always brought her a feeling of fear mixed with joy? And then when he talked to her, she immediately recognized his voice, it was the guy who fixed the locks for her house before!!!
