She relied on me, who was a teacher until a few years ago, and told me that she wanted me to take care of my bad-behaved niece in a few days.The niece I met for the first time in several years has blonde hair and a miniskirt.She's obviously a problem child, but just when I vowed to rehabilitate her by taking advantage of her teacher's experience and treating her like an adult, she teased me with a cheeky attitude.I tried to calm her down by telling her that the other party was my niece, but I couldn't put up with her fair-skinned big butt, and I immediately fucked an adult...!
