Really like
17MOONKEYS art style. The LIs are thicc and very attractive while still being visibly mature (whether they have cocks or not).
Normally the aunt-in-law wording seems to be just an attempt to try to get around Patreon's incest ban and it never works. However, it really works for this game. The only question that was left on answered was whether Alexandra was MC's father's brother's wife or MC's mother's brother's wife.
As for where the store should go now, it obviously has to revolve around the doll.
All of the sexy stuff started after MC met the doll, a doll that grants you your desires. Now that the MC has taken the doll with him, what are his true desires to be granted?
This has the potential to be an amazing Netori story, with MC meeting and seducing hot MILFs through the power of the doll.
Three or four more chapters as MC ensares a few more lovers, granting them each *their* true desires, and then a final chapter as he brings them all together in one home.
But to keep the horror tone, the doll could start asking for more and more extreme behaviour from MC, and he's going to be at risk of losing everything if he lacks the mental fortitude to resist these darker desires.
For the LIs, Alexandra is already caught, and after their night together she could find that she's pregnant (her true desire).
MC's mom is another of MC's conquests, but her great desire is maybe to be dominated, to have the control she normally has in their relationship taken from her and her made subservient to MC, leading to her divorcing MC's father.
Have an underlying theme of corruption of the MC by the doll, include a backstory of Alexandra's mother coming to America and almost getting completely corrupted by the doll, and the wrap everything up with either the doll being destroyed (freeing MC from the dark impulses - happy ending) or MC giving in and self destructing (true horror ending).
