A chuckle came from Percy's mouth when the lady first spoke about her punishment as a harem girl - a polite sort of chuckle which indicated he wasn't really listening to what she had said. That is, until she began calling him Master - he hadn't put the two things together, along with the fact that she was in a harem girl costume. At first, he was nervous, glancing around to see if anybody else was paying attention to this. Blatant displays of sexual attraction was not Percy's thing and it rather made him embarrassed.
Lips sealed into a tight line, his posture stiffened the closer she came, though he had to admit there was something extremely arousing about this scenario... something that would fuel his fantasies, later.
The cookie was right up to his mouth, but instead of biting it, he reached up to carefully pluck it from her hand when he realized what she'd mentioned. Almond? Now that he thought about it, the voice sounded terribly familiar.
"You... wouldn't be talking about almond croissants, would you?" he tested.
