My sister is away on a business trip, so I'll be taking care of my niece for a while. I met my J-girl niece for the first time in a while, and I could tell at a glance that she has big, plump breasts. Her budding breasts are still developing, and they're too dazzling for a middle-aged, single man like me...! I couldn't resist the sight of her bouncing breasts as she leaned forward, so I immediately fucked her! I sucked on her delicious fair-skinned breasts over and over again, made her climax with an adult piston, and creampied her tight pussy! I injected a lot of sperm into her undeveloped uterus!
