He shouldn't laugh. Shouldn't, but after a pause in which he watched Kurogane's naked ass retreat into the main building, he couldn't help himself. It was a childish little laugh, more from his own amusement than Kurogane's plight.
Realising that he probably ought to go look after his friend, he looked down at the ruined furisode beneath him and sighed. It was probably ruined from all the water, but... he can't even bring himself to be upset about it. Not when he and Kurogane had just been sprawled naked and entwined together on top of it.
Dressed in the thin under-gown, Fay walked back into the building, keeping quiet so as not to wake Mokona. His heightened senses picked up on Kurogane's scent and sound immediately. "Kuropon..." He knocked once on the bathroom door, voice gentle and free of any teasing. "Are you alright?" He had Kurogane's towel in his hands, ready to offer the other, still very naked man.
