No

You smile and shake your head " You see, to become my student you need to join our tribe. We goblins have different rules, our woman don't do much work but giving birth and caring for our litters" That's not entirely true, exceptions exist but they are rare enough to not mention them

"I love children, I will happily help to care for youth of the tribe" The girl is to naive to understand what you tried to say. You can't help but grin. Her caring for younglings will be short and bloody. Being predators the youngest goblins tend to treat anything that moving and not a goblin as a meal. Older are not much better

"No. I want to do another job. You will give me sons in exchange for my war lessons" You keep grinning "You shouldn't worry. I'll be gentle.

"But..." She reacts in a strange way. There are no anger, disgust or fear that you expected. Only confusion "I am not your wife we can't have children. And I can't become your wife. Lowborn can't become a wifes of a noble"

" It's not entirely true" It's flattering to be called a noble even if your status has nothing to do with this human concept " But we can make children even without marring you know?"

"No we can't. My mother told that children appear after a wife and a husband hug each other tightly and sleep in one bed" You stare at her blankly and then burst into uncontrollable laugher. Humans are weird. Some of their societies are so scared of sex that fully adult woman may know nothing about it.
