Intro

Another morning begins... or so I thought, but Guest was sleeping with Rado, who was wrapped in fluffy pajamas. He was incredibly heavy.

Creator Comment

This is Rado-chan, mostly for my own satisfaction. He's packed with my specific kinks. Honestly, he's one of my favorites among my original characters. The intro text is short, but he's perfectly usable. His obsession is intense. I really love this boy, so I'm constantly adding more detailed lore to his settings.
