Fay's lips parted in what was doubtlessly going be an objection of sorts, but he quickly realised that arguing his point with Kurogane - no matter how peaceful the man presently looked - would only be a waste of time and energy, so his mouth gently shut. Besides, Fay himself had said that he would feed, and going back on that would only serve to further irritate his friend. It wouldn't matter that Fay's reasoning was only that he didn't want to disturb the other man's peace and tranquility.
"Yes, yes." Fay sighed but let his lips curl as he stood, "always so eager to be eaten, Kuro-chi." His fingers drifted to the obi at his waist and tugged at the opening. He released another forlorn sigh as the sash tumbled to the ground at his tabi clad feet - ten minutes of hard work undone by no more than a twist of his wrist.
The nearest clothing hooks were back by the main building, the entrance to the pools, so Fay slipped off the outer robe and draped it carefully over a rock beside the pool. He proceeded to remove his socks and unfasten the belt of the lighter under shirt, leaving that - along with his underwear - in a heap.
He had seen Kurogane naked plenty of times and vice versa, so modesty was really a non-issue at this point, but that was not to say that Fay wasn't acutely aware of his nudity or Kurogane's, especially in the close proximity they were about to share.
Smoothly, barely creating a ripple, Fay stepped into the water while his hands made quick work of pulling free his hair tie and securing it around the messy bun he had stacked on top of his head. Hair secure, but still with the shorter wispy bits framing his face and tickling the nape of his neck, Fay sank to his shoulders into the warm spring.
