How about a link to the fan art thread and let that be the end of it?
If you look at the original game, once Eric left, then some of the girls came in to fill that role. Kira, then Alice herself. Basically before Eric leaves, the game is about trying to get sex despite his best efforts to stop you, after that, Alice and Kira are the ones slowly drip-feeding the MC access to the other girls in the house. Kira uses the MC to sleep with her sister before Max can get to her, and becomes the person in charge of Lisa's sex ed. Alice becomes a super dominatrix, using Lisa and Max to make money as well.
Kira is the centre of the story for me, well her relationship with Ann. I see it as Kira trying to prove anyone could have gone her route in the proper circumstances and that Ann isn't better or more moral than her after she's been the black sheep of the family for so many years.
Ann of course has her own issues she almost personifies the Madonna/Whore dichotomy after her childhood abuse she's basically been turned into a submissive because her life literally depended on it so now she keeps an iron grip on her emotions and is either completely abstinent or subject to someone elses will she lacks almost all agency in the game even her rules come down from other peoples suggestions (the 1st iteration of the spankings may be her own but again is part of her attempt to maintain Iron Discipline that backfires so badly)
In Glamour you have a series of protagonists and an expending rosta of young ladies to work with .
Phase 1 is the initial corruption
Phase 2 getting out from under Alice
Phase 3 Karen and the School
With new opportunities at each stage, Family, Friends, Schoolmates, Teachers though I can seriously live with a lot less Kate I know the Dev's repeating art assets from the other thread but so much Kate the Doctors office thread, Kate and Julia which is basically Kate with minimal Julia and the the after class shower and these are all running at the same time so it's all Kate all of the time. anyway I'm sure it was someones best time in the game just not taste (Now tell me there's a scene with Kira and the biology teacher and I'm there )
