Haven't finished the game but I am far enough to say this: MC's mom is a fucking riot. She is hypocrisy incarnated, her brain only works for what is convenient to her. She didn't even need the mc to seduce her at all, she seduced herself out of her own lust, all it took was for sheila to take her toy away and she started lusting harder and harder for the MC until she became obsessed and infatuated with him.
The mc didn't get the chance to drug her, he didn't seduce her, hell in a lot of scenes he was out right mean to her because of her shitty views and what she did to him, he didn't try to make a real move that she could notice until she was barely wearing any clothes trying to seduce him, she freaking seduced herself out of lust.
And I have to say, I love it.
Most AVN's I've played that have mom/son incest have the MC slowly trying to win the mom over from 0, which usually takes forever and makes her the last Li to fall. And a few others have the mom already having those feelings from the beginning but having troubles acting on them because of their values. This one is neither, She didn't have those kinds of feelings for him, she just felt guilty for abandoning him. And the MC didn't get the chance to do anything, he was to busy with everything else. Then Sheila takes her toy away and just by MC being in that house she spiraled down on her own lust until she wants nothing more than to be his bitch, it is freaking awesome.
As for the game in general, I really like it. It has its flaws and is still missing some things that will be implemented later but it is funny, entertaining, interesting and hot. at least in my opinion.
I may make another post once I finish all the current content (I'm at the public baths event right now).
