My mother Miyuki is the horniest of all. It was when my father had been on a business trip for some time that I, her son, realized this. Frustrated with sexual desire, Miyuki became so engrossed in masturbating that she didn't notice me watching... Her appearance was just too erotic. Knowing full well it's a forbidden relationship, yet the son pursues his mother and she can't refuse him. The two, having crossed the line, seek each other to the extreme.
