There's a lot of inconsistent art on all the major characters during the story. Skin tone, muscle density, face details, sometimes hair color, etc. I know it's generative AI but it's still blatant. The skin tone and muscle density during sex scene are the two most noticeable.
As for the weird feeling i'm talking about, well first a father and a son banging the same girl. I feel it also just goes into the horny territory real fast, plus the son overall character isn't likeable so far. I have a hard time enjoying the story for these reasons.
It seems that it wasn't just me who had this feeling of strangeness, it really bothers me to think that the father and the son will have the same woman, even more so having so much difference in that same place giving the feeling that the son will only serve to be a doormat while the father enjoys all the fun
