Its about his pride and ego. By taking a younger lover, called Kan, he is basically being told that he cannot satisfy his wife anymore. Its more loss of face then anything else. He is afraid too that if he divorce his wife, everyone will find out he had been cuckold, and suffer even greater loss of face. This way, he want to punish Kan, and satisfy his pride a little bit, and then keep it in house. I have fucked many married MILFs before. But Never ever fuck them in their place. That is just fucking stupid. This Kan guy is either too cheap or too poor. Even the back seat of a car is better then going to her flat. What a fucktard.
