She can't

"No. " She answers after a long pause " Daughter of a chief of Amazon can't be fucked in a front of nearby tribe. That will be not a sign of alliance but of subjugation. Each and every of your goblins will decide that they can own Amazons" Sheila makes wrong assumptions about but you decide against trying to explain customs of goblins and the Amazon continues "If you want sex with me as a price for aid in the war with orcs. You can take me. But I'll not agree to a public humiliation of my tribe. It will be better if we'll lose glorious battle against orcs than if everyone around will think that my tribe are sluts. My counter offer is simple. You put your green slimy dick in me here and there and then your tribe provide one-time help to our tribe. And that is all. Later we will meet at battlefield as enemies, pervert"

"Sheila..." You intentionally use a mentoring tone "Your lack of experience in whoring yourself makes you unable to evaluate your body properly. You are a hot piece but it is not worth life of my warriors. Also, it would be easier to **** you and provide no aid at all " You enjoy her anger for few seconds and continue

"Don't worry I'll not use your goods. You see, I can control my impulses. Besides, while you are a very beautiful woman, I am not that kind of person who would enjoy sex with a person who despises me. With a person that is stupid, rude, disrespecting and manlike in behavior" That is rather far from truth, you wouldn't mind to put Sheila on her fours and bang hard. You say all that to return an insult, women usually dislike to be told that they are not desirable.

"Very well" Sheila answers hissing her words through her white teeth "Good for me that you have no taste for woman, chief. Can I go, shorty?"

"No. Foolish little girl" You bark. That disrespecting woman does make you angry " For words and tone like that you deserve to be impaled. But you are lucky I don't want a war with your tribe. Furthermore I want your tribe alive and prospering. So I'll come to your aid only because you are enemy of my enemy. Now begone!"
