Is Chona a prostitute? I hope not, it would lessen the emotional impact of any sex scene.
I mean, the whole purpose of NTR would be defeated from the start.
It could be saved if NTRMAN focused on the slow destruction of the emotional link she has with her son, but it would require a great story telling and not just a compilation of sex scenes. But knowing how he tends to rush the story, I unfortunately don't have high hopes.
