I agree with you after the first post of most games it starts off with xx family member(most brother) comes home after xx amount of years of being away. When the door opens seeing xx's mother something clicks and xx starts seeing xx's mother as a woman then jumping in xx little sister who turned into a super hot young woman which xx starts to lust after only seeing her for a second.
For Doc's games you have to guess what kind of mood he was in when writing the script (looking at 23 Sisters mostly). The fact that we can't guess what is coming next in the update is what makes Doc's games worth playing.
I will say I'm starting to look for games that you play as the mother (
Her Desire is my favorite one so far more so then A Wife and a Mother..... Ok that is do to the dav of Her Desire puts out a update so far every month).
