My sister asked me to take care of my niece for a few days because she had to go on a sudden business trip. It had been a few years since I last saw her, and she'd grown into a cute, serious-looking, black-haired beauty. However, the moment we were alone, she purposely teased me by flashing her pale, big-assed panties. No good... it's my niece... she's my niece after all... I tried to calm myself down by telling her, but my dick was out of control and I got a disappointing erection. To maintain my adult dignity, I rubbed my dick against her panties and splashed it all over her! Taking advantage of the opportunity, my niece was taken aback by the sudden cumshot, I immediately plunged my penis into her and punished her! I made her cum over and over again without asking for permission, and she finally understood! I splashed my cum all over her panties and creampied her over and over again until she changed her attitude!
