When Itachi had first walked into the Akatsuki lair, Pein had been sure there had been some mistake. The records he'd obtained said that Uchiha Itachi was a man. This person standing before him did not appear to be a man at all. Immediately Pein pulled her into his office. "You are Uchiha Itachi?" he asked dubiously. "I will not take spies in my organization."
"I am no spy, sir," she said, and her voice was musical. It was of a lower timbre, but simply sounded like an older woman's voice. She must have seen the hesitation, because she quickly removed her shirt as if she knew exactly why Pein doubted her. Pein blinked as the shirt came off. There were no breasts. He reached out and prodded Itachi's chest area to be sure. That chest was hard and chiseled, nothing like a woman's soft curves, and flat as the plains of Kansas. Pein was entranced with that pale skin. He couldn't take his hand away. Itachi shivered as Pein's fingers caressed over his nipple. Pein smirked.
"This could be an impressive genjutsu," Pein said. "I believe I'll be needing more proof." The boy below him smirked too, hooking his fingers into his own waistband.
"Of course, sir," he said, and now Pein could hear that it was the tone of a teenage boy who's voice hadn't changed completely yet. The pants fell to the floor.
Pein loved respect for authority.
