Hiei couldn't help but smile as he opened one eye, watching his mate roll in the grass under the assumption that Hiei was asleep. When they vacationed to Makai, Kurama took the opportunity to spread his wings, so to speak, and, when he thought the little hiyoukai was asleep, he would take his original form.

So, Kurama was merrily rolling around in a patch of highly fragrant blossoms, five tails whipping around as his fur caught the tiny petals. A tiny yipping noise, a quick barrel roll, and the kitsune hopped off again, bouncing off the trees like a hyperactive kitten.

"Hn," Hiei yawned, smiling and content to bask in the Sun while Kurama enjoyed a "private" moment of being a truly strange white fox.
