My 20-year-old silicon niece asked me to have sex and I couldn't refuse the invitation

I married three years ago to a beautiful woman who has an even prettier niece in her 20s. The bitch never saw me as her uncle and ended up getting more and more excited by me. My 20-year-old silicon niece asked me to have sex and I couldn't refuse the invitation. Check out this intense, incestuous fuck we had all afternoon while my wife was traveling.
