Push her away

With one frantic move you roughly push her away, forcing her to fall on her ass "Stop!" You order while breathing heavily. It is probably the first time ever when you declined sex being so aroused

"Us mating like that is against rules of your... our Goddess. You know that" You turn your head away from observing Thora's body. Body that is fresh as a spring itself "That will either mean that I am a rapist or that you are a whore. I don't want that! We'll marry first, mate later. Understood?"

"Yes, Master" She answers sounding confused and insulted with that kind of refusal

"Listen Thora... My race are not the most pleasant guys around. " You try to calm down but boner doesn't go away so you pretend if it isn't here" I told you truth. My tribe doesn't pillage, rape or eat sentient being. It is not because most of my subjects think it is unacceptable. It is because of orders. My father banned eating sentient flesh" You omitted that corpses of fallen enemies were fed to the war dogs instead "And starting from today I'll ban rapes. I'd lie if I say that without my protection you wouldn't be raped and\or consumed today. "

"So your subjects are exactly like those that ruined my village. Ville animals" Thora say "Only you are a very strange goblin"

"I don't think so. I am sure that those was one of the wild tribe. We are different. We have skilled crafters, we can build huts, we have cattle and start learning farming. We have clean clothing and drink boiled water. We have discipline and order. But we have many more things to achieve and I need your help"

"My help?"

"Yes, Thora. Yes. I need a missionary that will explain my people why rape, murder and consuming bodies of creatures that had soul is unacceptable. I need an assistant to setup proper farming techniques and I think you know something about that. And I need a divine support... Your arrival is a sign that the Goddess of Spring, mighty Freyala blessed my tribe. I can only repay her with becoming her servant. I know quite a lot about your cult but you'll need to teach me more"

"Yes, master" Thora keeps talking with short phrases, likely to hide her emotions

"Now my dear, I need to go. Your beauty is too much for me to handle... And as I said I want to mate with you only after a proper ceremony " You make few steps toward exist but got stopped by words of the priestess

"In the name of Freyala I announce that Thora and Vehumet are wife and husbands" Than comes a sound that you never expected to hear. Thora giggled loudly "It's that simple, words of the divine servant is all ceremony that we need. Now, Master-Husband, you can take your wife" You turn around and see that Thora assumed a position on her back and invitingly spreads her legs

You can't understand why her mood changed from anger to oblivious horniness but do you really need to know?
