Well, let me throw some diverse things at the wall and see what sticks.
As an example of a typical trope in japanese manga - a mother provides sexual favors to her son, so that he will study well, like that.
An erotic western comics series about adventures of a female spy who seduces guys left and right to further the goals of her secret service. There was a point where she provided sexual services to some civilian to get his help too. Quite a funny stuff.
It's not on f95zone, alas, because of some small shota part of content. It already has a good official english translation as
The Scarlet Demonslayer, and you can find it easily enough. There was some more old, fan-mtl translation, don't fall for it.
A bit especial thing for the guys with "emotionless" fetish about a powerful girl gradually breaking bad, when she lost some of her powers, got a succubus ring as a temporal solution, but it's changing her common sense. She's sucking power from getting seen when she's getting groped, etc. So, she's pretending to be coerced even though she can easily kill the guys. Or she pretends to be a "hotwife" of her subordinate in a village they're visiting. Ah, and the succubus ring allows her to hear the lustful thoughts of those who see her. And that's getting escalated. She's not forced with any violence or blackmail, she's in control from the beginning to the end.
Overall, Queen in Deficit offers a unique perspective on a topic that is often shrouded in secrecy and provides viewers with a deeper understanding of the financial realities faced by a reigning queen.
