What he meant by 'claiming'

Itachi clasped his hands in a contemplative gesture.

"I'm not sure if you understand the meaning of 'claiming'."

"Er... You mean sex stuff, right? I'm not that stupid."

"It's hardly just sex, Uzumaki."

Naruko felt her spine shiver. If it was apprehension or excitement, there was no way to tell. But, indeed, her lower parts began to moisten and the sheer possessiveness in Itachi's tone. The words had a slight animalistic growl to them.

"If you insist on this endeavor, Uzumaki, you will end up mine, and the thing about becoming mine is that I will take all of you. As any male worth the name, I will have the right of property over the woman who marries me. Your dreams, your ambitions, all of it will take a back seat as you assume a secondary role to me in all things, is that clear?"

They sat there together, in silence once more. Naruko, with her head lowered, desperately trying to focus on the calm surface of her tea.

"If this is what you wish for, give me your hand."

Any other day, she might have had the strength to refuse, to resist her darker instincts, but that day was not today and the call of her duty, her mission, spoke in a single voice with what she desired deep inside.

She gave Itachi her hand, and the Uchiha slipped a golden band through her ring finger. His head lowered and, as a gentleman, he touched the back of her hand with his lips.

"Mine." He whispered.
