I decided to take care of my niece, who I had been interested in for a while, for a day. She wants her to grow up quickly. With that in mind, I moved to the bathroom while it was still light. I helped her change her clothes and went in with her. My dick was already getting bigger and her niece was looking at me curiously. Washing her breasts and lathering her eyes... Her niece has grown up more than I expected.
