My sister went on a trip, so I decided to look after my niece for a few days. When I met my niece for the first time in a while, she had grown into a beautiful young woman. Her uniform blouse was tight and her breasts had grown beautifully. When I was mesmerized by her big breasts, she treated me like I was making fun of her, so I immediately fucked her and punished her with a piston-like piston! I made my niece climax many times until she cummed with tears in her eyes and regretted it!
