My sister and her husband are on a business trip, so I have to take care of my badly-behaved niece for a few days. The niece I haven't seen in a while is completely in her rebellious phase, a total brat J-system girl. She treats me like I'm invisible, and her blatant panty shot catches my eye. Though I thought I shouldn't look at my niece's panties, my male desires got the better of me and I couldn't hold back, immediately punishing her with a piston-like fuck! I kept making her cum until she changed her attitude, and she grew into a love-doll meat toy that craves my cock!
