Niece and Uncle
I'm a 27 year old woman.
Right or wrong, after my fiancee cheated on me for the 4th time I dumped him and threw him our of my apartment.
At that moment I realized there was only one man in my entire life who accepted and loved me as I am. My Uncle Jack
The next night I went to my Uncle's house, let myself in with the key he gave me. I stripped in the hallway and went to his bedroom and seduced him.
He tried to resist but in the end gave in to me.
It's 4 years now and we have been together since that night.
Hopelessly and madly in love.
