The husband was away on a business trip, and the wife had an affair with her husband's subordinate

The husband was away on a business trip, and the wife had an affair with her husband's subordinate. A lustful and meat-filled wife, after a party at her husband's company, secretly had an affair with her husband's colleague and subordinate. Taking advantage of her husband's absence, Sakura invited the other guy to her house so they could spend all their time making love. Not only that, that guy also invited friends to visit Sakura's lover. What a prostitute, perhaps because of lack of sex from her husband, Sakura had to do this, so is she at fault or not?
