My very beautiful 17 year old *niece* (Ive been her FOSTER Uncle her entire life) told me, Her Uncle, when we were alone last week, that on her 18th birthday which is in a few months, she wants me to F*** Her! I was and AM SHOCKED! I am shaking..its wrong, SO WRONG…BUT Im a 50+ man! Im her favorite! ITS SOO TURNING ME ON FOR SO MANY REASONS! FANTASY COME TRUE!! I feel so guilty. But I want her when shes 18..Im afraid I wont be strong enough to say NO…
