A lewd stepfather who has retired and is now free to join his wife

It's been three years since I've been married. I look forward to the new family joining me. Although she was in a situation where she could be considered the peak of happiness, Airi's heart was not clear. She is troubled by the persistent sexual harassment of her father-in-law, who lives with her, and her husband, doesn't listen to her, and she has not lived in the evening because she is busy with work... Airi was isolated and unsupported within the family. Frustration expands day by day. Escalating sexual harassment by my stepfather. Airi is cornered and weakened, and finally, his old, dark desire bares his fangs.
