[Hashimura Aoki] I Was Reincarnated as a Sorcerer, So I Tried to Enslave All the Princesses Ch. 4 (COMIC AUN Kai Vol. 23)

Princess Melia, the empire's most powerful royal, plans to crush the sorcerer with a hoard of monsters—only to summon an army of cats instead before his chains finally claim her. Bound and stripped in his dungeon, she receives a demon seed meant to turn her womb into a breeder of combat monsters, then endures public breaking under the whip until her bratty defiance cracks. The chapter closes at a slave auction where four former imperial princesses, bellies and crotches numbered 59 through 62, are paraded before a jeering crowd and sold to the highest bidder.
