Light of my life (my favourite so far) - great story, and dialogue and arguably the best character development Sisterly Lust- likable characters with optional Harem ending.

I'll second those opinions. You may also be interested in:
Parental Love and Midlife Crisis - Both harem type games with plenty of family members to suit your fancy. Midlife Crisis updates frequently and Parental Lust is almost complete. These two aren't spectacular in the character and story department, but they're certainly worth a look.
Single Again, Radiant, and Dr. Amana - Not much in the way of incest content yet, but these three games look promising.
