It starts with female main character essentially being sold to become the Count’s concubine to pay off family debts. Female character runs off.
Then male main character is forced to seduce female main character for the purposes of his conspiracy group’s rebellion. Which he does by force.
Male main character goes off to do undercover stuff while female main character hides. She gets attacked by one of male main character’s collaborators. She flees to someone she thought was her friend who then sells her into prostitution. She’s put on a boat where she’s again attacked, but uses her witch power to save herself.
Meanwhile male main character gets wrapped up in an elaborate plan to trick a high born lady into having sex with him. That fails. He later has actual old fashioned relatively healthy consensual sex with a serving girl. Later his cover is blown and he has to flee. He gets on a boat where the captain attempts to make him pay his way by being the captain’s boy toy. When he refuses, he’s beaten and accused of mutiny.
Female main character is horrified to learn she’s been sold into prostitution. She refuses to cooperate and is arrested for failing to pay her way. Male main character finds her but can’t save her until they’re saved by a Knight guy who takes them back home.
Knight guy later tries to force himself on female main character, while male main character becomes a clerk for a judge. One of the two cases we hear in detail involves the brother of a baron who wants to kill his nephew so that he can be with the nephew’s wife. The other case involves the concubine the Count got after he couldn’t have female main character; she offers male main character sex in exchange for her freedom.
It ends with the two main characters running away together to get away from this sordid mess.
If these were a few details in a 600 page epic with a bunch more going on, that’d be one thing. But this is about a 180-200 page book and what I wrote is pretty much the entire plot short a couple details.
