As a writer, I think Mom/Ann's biggest malfunction is her traumatic experience when she was younger -- I'm referring to Kira's revelation. I am not spoiling it, but it explains a lot about the perverted spankings, and Mom/Ann's attraction to twisted alpha males like Eric (ugh). I hope DarkSilver is going to resolve it through Lisa's sex-ed, because I honestly think Lisa reminds Mom/Ann of her unspoiled self, before that traumatic experience she went through in the past. That's why any story developments revolving around Lisa and Mom/Ann is interesting to me (I know, I know, if this went on in real life, it'll be considered psychological neuroses, but hey, this is a sexual fantasy we're talking about here). I am really, really looking forward to it.
I have great reasons to be optimistic, because I love how DS broke Alice out of her submissive self to Kate by being a dominant older sister to Max and Lisa -- I applaud DS for making this choice, because even though incest among siblings is neurotic, having an overbearing authoritative eldest sister is somewhat normal (I have one, ugh, so like a tyrant at times).
If the story of Alice is any indication, DS is going to continue developing these characters -- interesting storylines that addresses their problems bit by bit, and eventually makes them better people (still twisted, but better) in the end (I also honestly want to see how Max evolves beyond being a horny perverted moronic kid, that's where Olivia and Vicky comes in, but I'm not sure, haven't played those storylines yet).
