Itzel smiled at him. "Well, I only know what I know from medical books and such." he replied before he gently took Naoki's tail into his hand and gently felt for one of the small vertebrae within the tail before taking one of Naoki's hands and making him feel that same area. "See? Those are the bones in your tail. It's like an extension of your spine, but without the spinal cord."

First Naoki gasped but then started to do what Itzel wanted him to and nodded his head slowly.
"Uhm.. What is a spinal cord?", asked the neko, still touching his tail although being rather cerful with it.

"It's a long, thin bundle of nerves that send messages to your brain, like little tiny messengers." Itzel answered as he watched Naoki feel his own tail for the small bones still.

"Oh...", he muttered and then tilted his head a bit as an idea popped inside his head. "Mhm.. Itzel. You think that after learning how to read you could maybe.. teach me a bit about body? It seems like something really interesting.."

Itzel smiled hearing that and he nodded his head in response. "Of course, Naoki. I would be glad to teach you anything, and I promise that me and Simon will get you able to read in no time." he said sincerely.

"Really? It would be really nice to be able to read~", he said, purring happily and really excited.

"Really." Itzel replied with a bigger smile and he leaned in to kiss Naoki's forehead. "I know things will be much easier for you once you're able to read."

Naoki smiled and nodded his head.
"Yes. They would. And there's no one I know that would want to teach me anything like that so.. mhm.. I really do appreciate it", he sighed and then looked at the changing room where more outfits were ready to be checked out if they fit. "Let's see the others.. if you still think I should have so, so many things.."
That said he went back and showed Itzel each and everyone, with the shapeshifter showing him what he thought would look nice with what. Then he looked on the last piece of clothing and blushed really hard.
"What is that?!", he whimpered, looking at leather skirt.

Itzel had to admit, he liked the first outfit that Naoki showed him, and the leather outfits. The very last outfit before the skirt, Itzel had a hard time not blushing towards because it complimented Naoki's legs and waist. When Naoki asked about the skirt, Itzel blushed a little. "I-I must've picked that up by accident." he said softly. "W-Will you try it on...just...for me?" he asked.

Naoki glared at him but couldn't stay angry when he saw that calm man blushing like that.
"By accident... right..", he grumbled and put it on. "You're just as perverted as Simon is.."
