DVAJ-483 How a stepmother creates sympathy for her husband's beloved son

It's been three years since Nanami started treating her son sexually. That's when I first helped my son retreat to his room and continue masturbating, feeling dangerous. Of course, I knew it was wrong, but I convinced myself that it was only a temporary measure until my son returned to society. Her husband seems suspicious about their relationship, even though he doesn't understand the problem. I told myself to break off this relationship as soon as possible, but my son kept asking to sell his body without listening to Nanami's persuasion. That's how the sloppy relationship continues.
