But why you added Sandra then? She could be Adrianna's mom, instead of being just random silver-haired milf in her 50's.
I'm not arguing or trying to change your opinion, just curious. Artist for sure should do what he likes.
Btw you always can go with mini-events like: Adrianna's phone calling, oh, it's her mom, "hey, darling, my friend sended me the link to your porn page, to say I'm shoked is not nearly enough, you are such a slut, you even dragged my sweetie-pie Stan into it, you are failure as a mother...", then, talking to her husband(Adri's dad), "what do you mean send that link to me too, you fucking pervert?!".

I mean you don't have to properly develope every new character that appeared in the story, in this example granny does not even need 3d model. So this way you can spice up the story a bit with new interactions (and then make these characters disappear) and also can please, in some way, those who wants to see more of such social dynamics as mother-daughter.
