After being laid off, I moved in with my younger brother and his wife. That's when my life changed—my once-little niece, now grown, started flashing her bare anus at me, teasing me with mischievous moves every day. "Uncle's such a pervert, getting turned on by staring at my butt hole~," she'd whisper sweetly, then mount me in cowgirl position, grinding her tight ass onto my face before riding my cock with relentless anal-displaying thrusts until my balls were completely drained. Caught off guard and helpless, I found myself sinking deeper into her seductive trap.
