My wife, who had been making me cling to him, was really clingy. NTR of regret

It's been 10 years since I married my husband, the owner of a company. His wife, Kanako, was given a role by her husband. This involves physically entertaining an executive at my husband's business partner. However, the husband's true purpose was to have his wife cuckolded by someone else and be aroused. Then, one day, her husband makes Kanako cuckold by the driver Takayama in front of her eyes. He is a miserable man with no position or money, but he does not betray him. I was excited when my wife was being cuckolded by such a man. However, when Kanako is embraced by Takayama, she discovers a pleasure she has never felt before...
