Seeking Decent games with sis/sis or sis/mother scenes

[goddlike]

As mentioned in the title, looking for games where the women in the family have scenes together. So far I've only come across games where they just have sexual relationships with the male MC.

Decent writing would be a bonus.

Definitely Parental love. Install walkthrough mod and go harem route.
Mother, 2 daughters, aunt, girl friend and all possible combinations of them(well, atleast in later half of the game).
Decent graphics, scenes and writing included.
