You realize the problem is pretty much solved

Now the orgasmic haze has subsided somewhat, and the blood has returned to your head, from the other one, you realize the problem is not that significant.

Jewelries? There's already some shiny rocks drop out of your pocket on the way there; perhaps those are the so-called jewelries the skank was referring to.

A fine horse and a carriage? Of course, she is going to need one if you get her pregnant with your bastard. You don't want the baby to pop out during the ride, right?

A maid to help with the labor? She makes sense, since you don't want her to be tired, or give the excuse that she's tired, when you come to fuck her. A cute maid, not some nasty, judgmental old crone who'll gossip to every crone in the city? It has to be a cute maid, since if you're bored with the normal sex, you can get the maid to join in. Or better yet, fuck the maid and get her pregnant! Then you can get the crone to take care of both of them.

A nice new home? New may not be the right word, but your castle is the best kind of home, fully furnished, and comes furnished with the stable for the horses and carriages. It also has fuckable cute maids, as well as fuckable crones if you close your eyes while fucking them. Eva might think that you're some gullible baron's son or something; you're actually the king, even if she got that part of you being gullible correct.

So, the way forward is easy. You can give some money to her, pretend that you're going to do what she's asking, and just return to the castle and not come again. You may get her pregnant, but that's the possibility Eva had already considered, judging from her response earlier. Even if she finds out that you're the king, it's not that she can come and demand you to take responsibility as it would be her words against you, the king.

Or, as your dick is telling you, claim her as one of your mistresses and get her into the castle. You get to keep her away from those stupid and gullible noble sons who may fall prey to her words, as well fuck her whenever you want, without having to travel to another place. You are a busy man, after all.

That reminded you, what happens to your father's mistress?
