Read this novel (I refuse to call it a game seeing as there is little to no choices within this thing and the ones that it did have were still one path seeing as the others lead to game over screens) and I have to say while it was nice seeing the MC getting some variety in the bedroom (Mother, baby sister, and one of his aunts) That phone call where the Mom literally saw her husband resist the temptation and claim he only loved her threw the biggest monkey wrench into the sweet mother/son incest we were seeing.
But at the same time what really gets me is the fact that between the two she is the only one who is truly suffering. The MC can claim he is hurting all he wants but it still hasn't stopped him from stretching out his Aunt Eliza's and Iris's insides with that monster in between his legs, as well as all the other sexual antics he is doing with his female family members.
Plus the way the novel ended to be honest spells disaster big time. With the first two hunts Both Mother and Son were free of issues and were fresh minded. However with the awkwardness in the air between the two of them I can see either one or both of them getting wacked.
