Suck~ Suck~ Suck~

"Woah! Hold on now, Nina!...Don't you know exactly where my hands have gone?" 

Kafka warned Nina about the hole that his fingers had just entered while still being shocked at what was happening and tried to pull his hand away for Nina's sake.

But when he tried to do so, he found that Nina wouldn't budge at all, and she firmly held onto his hand with both of her hands wrapped around his wrists, having no intention of stopping sucking on his fingers like it was a lollipop. 

Suck~ Lick~ Slurp~

She even looked up at him with a dangerous glint in her eyes when he tried to disturb her, almost like a cat when someone tried to steal its food, and he could even almost hear her purring viciously, like she would scratch his face if he tried to pull his hand away again.

Kafka didn't want to risk the chance of getting his face all scratched up by Nina's abnormally sharp nails and let her suck on her fingers as much as she wanted to.
