Glory Quest did a great series with the prefix ACB but, as far as I can tell, only did six films. They are wonderful! Don't know why they didn't continue with more.
ACB-01 and ACB-05 share a common theme: a young servant girl is brought into a couple's home and they both take advantage of her sexually, solo, and then together. The endings are dark...
ACB-01
ACB-05
ACB-03 and ACB-04 also have a common theme: a housekeeper from the countryside enters a household of deviants and gets used if not abused. Again, a dire ending on one of these.
ACB-03
ACB-04
On a lighter note, ACB-02 and ACB-06 has the theme of an aunt who debauches a young nephew. ACB-02 features a young Reiko Sawamura, but I prefer Shihori Endou in ACD-06 because she gets kinky quickly!
