This NTR talks and examples with Becky/Gina etc reminds me of agreements of the spouses after many years of living together, like "cheat, but only the way that I don't know about it and don't see it".
We have Riona, Camila, Quinn and Pink Rose girls. The first two are hookers, which already passed a dozens of different dicks, it's even mentioned that Jamie for example fucked Riona, etc. Pink Rose girls mentioned that they have extra cash from "extra services".
The closest thing to "breaking the hidden rules" of NTR is Heather & Tommy.
In AL, we were able to help our friend to get one of MGs. Also we were able to reunite with MCs ex, who clearly cheated on him before.
So even though the DPC is careful, except that he does not intentionally make such scenes or show the MG or SG girls with someone else, but certain piquant moments are still present in his games.
Josy 7yo? She is lower than most of characters, but not like she is a dwarf. Sarah is pretty the same height. Petite thing, when it's not look weird or disgusting is a really rare case, but I think it's very cute in her.
Sage legs... you never met girls with really long legs? This is also her thing, her model and figure look unique in their own way, there is nothing worse than the feeling when all the models are almost the same and differ only in skin color and hair. Skin tone are mostly like a DAZ & lighting problem. It was really weird in a couple of scenes, but it solved since.
Maya... I'm going to say something unpopular now, but most likely the textures of her model are just too real and detailed in comparison with the others. Hell, in real life, people have various spots on their skin, pimples, and the skin on the pubis and on the ass is usually very close to what we see in Sage and her, with very very rare exceptions. Sage have the worst pubis look, btw, then goes Lily, then Maya and then the rest. It reminds me of grumbling like "We supposedly came to look at perfect bodies...", but damn, only silicone dolls for a lot $ are perfect. Another good example - Nicole. This is how it usually happens and looks like.
Jill - I heard it's DAZ models issue. DPC work with Genesys 8, while modern DAZ is on Genesys 9 currently, which are much more detailed, have more polygons and better pass through different poses, emotions and bendings. There are some tools to convert from ver 8 to ver 9, but it's not so smooth process as well as it doesn't makes models better. As I understand it just makes converted models compatible with new assets which are mostly made and released for last versions - such as hairstyles, clothes, etc. Who is well versed in DAZ - correct me if I'm wrong.
