Description: When my sister called me because my step-niece was not feeling well, I knew I had to get there right away. I'd do anything for them, even if I haven't seen my niece in ages. When I got there, I was shocked to see that she had become a beautiful woman. Guys at school must be dying to fuck her, but she still seemed so innocent. She was so embarrassed and confused when she wet her panties after I rubbed her chest! That's when I knew that as her doctor and her step-uncle, it was my job to teach her how to take good care of her body, so I gave her a sex toy, and I even showed her how to use it. Turns out, she was more curious about my boner than about the toy. She begged me to help take care of my hard dick, so how could I resist? She could barely fit it in her little mouth, but we managed. She's feeling much, much better now.
