A Beast Under The Sheets

"Nina, you said that the men in your clan used the aggressive nature they had developed to hunt and defend. But what about the woman?...What did they use their innate dominance for?" 

Kafka asked as he licked his fingers and rubbed the saliva on top of his fingers onto Nina's nipples—the place that Kafka had been biting, to be exact.

Her nipples didn't start bleeding like Nina wanted them to, but they were still injured to the extent that her purple protrusions had the indents of Kafka's sharp incisors surrounding them. 

They seemed like they really hurt and even looked like she developed red scars on her buds like blood was going to seep out at any moment, so Kafka was gently rubbing them with his wet finger to ease the wound he had created.
