Female investigator Honoka Tsuji goes into hiding

Honoka used to be a special investigator, but she retired and got married. One day, the husband invited his boss to his house, but unfortunately for Honoka, she had a bad past with this man and he knew some of her secrets from the past. He threatens to ruin her family's happiness if she doesn't allow him to have sex with creampie. And because she wanted to keep the family quiet, Honoka reluctantly agreed, and was brutally fucked by him.
