Meltys Quest (Good chance you've played this one before, mentioning it just in case.)
Princess Go Round (The scenes are especially sexy imo.)
Ordeal of Princess Eris (This one has several female characters, three of which are princesses.)
Salvation (Only one of the three main characters is actually a princess, but she's the central figure and gets lewded in especially humiliating and degrading ways. My fav Clymenia game.)
The Nobleman Retort (No princesses, mother & daughter noblewomen, male protag. Also by Clymenia.)
Rhode's Fortress (Haven't actually played this yet, should be pretty good if it's anything like the previous games from the same dev. The beginning will probably be painfully slow. Previous games also take a couple hours to get to the juicy content.)
