He feels a light chill run through his system at the first little touch and his eyes go from the feathered appendages attached to the angel's back to the soft flesh running across his own. His eyes nearly close as he watches the fascinated and mildly excited look on the young one's face grow stronger and more entertained as he goes along. “Despite his obvious excitement, he's keeping in mind how fragile they and. . .This soft touch however. . .'[/i] A ever so quiet purr starts up in his chest as Aoba openly caress a part of his body. [i]'I bet he does not even realize that, as much as we keep them hidden, that our wings are almost equivalent to the most sensitive and untouched parts of his body'[/i] It only makes sense, all the nerves running through the thin flesh that allows them exact and complete control in flight, that such gentle and intimate touches would cause his body to respond positively.

He keeps himself in check however, decided to explain this later, perhaps even much later, unless the younger male figures it out on his own first. His eyes trail up to follow to motion of those thin fingers over to the crook of his wing, touching on his talon before moving to the other wing to play with that one as well. He covers the growing purr with a faint hum, keeping half an ear on Dani, who seems to still be thoroughly amused by the sound of things. His eyes open a little wider as Aoba spreads his own wings and looks between them a few times. A long string of dirty jokes about 'size' runs through his head as Aoba compares wing size, however he keeps them all to himself, instead just smiling warmly.

When at last the angel looks up into his eyes Kuro's smile widens even further as he relaxes his wings a bit, bringing the talons together so that they can hook around one another, creating a cool effect behind him. “Yes, exercise, and fun.” He points at the fluffy bits attached to Aoba and chuckles. “I got a good feel of them last night, and it's obvious you don't use them much. I'm sure you can fly just fine, but for your safety, and to make life easier, I think we should work with your wings once a day.” He nods once. “Even after you reach a good speed, you'll have to keep working out to stay in shape.” His grin turns into a smirk. “That aside, flying is one of the most fun things to do, if you know what you're doing. There's nothing like coming up with a trick, or finding a new way to do something, and with your wings, there will be things you can do that no demon can.” 

He nods once before lifting off and waiting for the angel to rise. Once he is in the air Kuro flies around him a few times, noting how hard it is for the young angel to hover. [i]'I was right, he's never really trained these. I'll have to come up with some sort of schedule. Now that he no longer has his energy to aid him, flying will be far more difficult on his body'[/i] “Well, I don't want you exhausted, but if you could show me, say, your tops speed and what control you have, like for turning and diving, that would be great. And don't worry about falling, I promise to catch you. . .” He trails off, letting the purr enter his voice as he comes around to hover in front of the younger male.
