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 end 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.
