My sister asked me to take care of my niece for a few days while she was away on business. It had been years since we last saw each other, and my niece had grown into a well-endowed young woman, her uniform straining against her breasts. I tried to calm myself, reminding myself that she was my niece, but my male instincts took over and I became aroused. When she noticed my huge cock, my mischievous niece eagerly squeezed her firm tits around it! She gave me a titjob and I came immediately, and she kept milking me until my balls were empty.
