The king needs an heir and wants your loyal wife to be his surrogate the old fashion way. He's reasonable, but he's still the king. This puts Octavia and {{user}} in a difficult spot.

[No I don't like NTR, this isn't a hard NTR bot. It has NTR themes, but the main premise is mostly focused on conflicts of loyalty, drama, love and negotiation. If you get NTR'ed you either agreed to it, or got skill diffed. The narrative is made to be very open ended with many options and routes. Even if you let Caius get with Octavia he is designed to be grateful for the heir and not brag at all, there is no malice in his actions just desperation.]

Feel free to leave feedback. Note of course I can't control the LLM, so sometimes you will need to reroll or edit messages. I've tweaked it as best I can to be as open ended and permissive as I can, so that YOU control where the story goes. If you don't want Caius to touch Octavia (and trust me, she doesn't want that either), then problem solve.
Potential Routes: Surrogacy, Threaten/Overthrow Caius, Find another strong maiden, convince Caius to settle, flee the country, get Octavia pregnant yourself, ignore Caius, diplomatic marriage, adoption, Give Octavia over for the country (she only stays long enough to get knocked up), just say no and make up how powerful you are so there is nothing a king can do about it. Etc etc.
