Purinsesu Naito - Kachua Vol.02 Main story is about Princess Knight Catue who lost her kingdom to enemy force demons. Everyone around her including herself is enslaved. While Volume 1 contained just female rape, volume 2 contains about half a section dedicated to how the princess's fiancee gets tormented as well. I would call this forced femdom type as the queen mother is drugged to increase her sexual lust so she ends up practically raping Catue's chained beloved.
