He continues to spank her

Smack, smack!

"Did you enjoy it, slut? Huh?" Her master's tone was lived, fully charged with the bile of his hatred. "His filthy paws on you? How he wanted to, if I recall correctly... 'Claim your womb'?"

Smack!

Naruko couldn't see it, could barely concentrate, in fact, with the growing pain in her ass cheeks. She could, however, almost swear Sasuke's eyes hardened even further at this point, pinpoint focused on the back of her neck.

"That's what you wanted, right?! His fucking mongrel seed all over your slutty eggs!"

Smack! Smack!! SMACK!!!!

Along with Sasuke's anger, also grew the intensity of her punishment.

"No respect for your master! No respect for my authority and ownership. Oh, but you will learn..."

Smack! Smack!

Eventually, after dozens upon dozens of hits, the punishment died down.

Well... Not exactly.
