ROE-116 Mother, son, and nephew. An abnormal triangular relationship, fighting over the married woman Rieko with a penis driven mad by jealousy Incestuous Rieko Kataoka

During the summer vacation, I ended up taking care of my nephew Tetsuto at my house. With my husband on a single assignment and living with just my son Takashi, our life became lively, but Tetsuto has always been strangely close... Is it because he lost his mother at a young age that he's superimposing 'the image of a mother' onto me? Takashi, for his part, is sulking because he thinks I've taken a cousin as a husband... The sense of discomfort in the increasingly strange distances within our family, and then that thing appeared before me in a form I never expected.
