Captive Niece

As a cockteaser, Diane's self-worth was measured by the number of pricks she raised. But there was another gauge she counted on. In her own selfish way she believed that the bigger the cock she made stiff, the prettier she was. Getting boys hard was easy for her. When she got a grown man stiff, she felt terrific.So, to see her uncle's prick grow so immense made her feel great. His stiff cock verified her own opinion of herself: she was sexy, beautiful and irresistible. She loved it. It didn't matter to her at all that she might be causing her uncle untold pain and lust. That was his problem.
