From Guardian To Lover

I'm in a sexual relationship with my own niece. We're in love. I was not a part of her life for most of it, but I came back to my home country about three years ago, and that's how we met. She was already a teenager. Even back then, when we first met, I could feel some sparks fly, but obviously I never acted on it.

She's my brother's daughter, and he tragically died along with her wife in a car accident shortly after I came back. He named me their daughter's legal guardian. I would have refused, since I've always wanted to be single and without kids, but I felt guilty, and she was only a couple months away from turning 18. I took her into my house and figured that, if she wanted to leave after turning 18, I'd let her go.

From the beginning, she was very openly and unapologetically sexual, a very open-minded young woman that liked to walk around the house with comfortable clothing, paying me no mind, bringing guys home. I let her be, but I could feel the tension building. We became closer as we consoled each other over our loss. By the time she turned 18, we were very close. Our chemistry was already... peculiar by then. It was only a few weeks after that that she came home drunk one night, her friends dropped her off as she was barely able to stand. As I put her to bed she kissed me. I tried to pay it no mind, but I felt very turned on and jerked off thinking of her that night. When she admitted to remembering the kiss the next day, we gave in to our attraction.

We've been lovers in an open relationship ever since. She stayed to live with me, and most times we sleep and fuck together. We pay no mind to the age gap or to our being related, we're just careful with birth control (she likes to take my cum bareback and I don't complain). We're in love, and we plan to stay as a couple as long as possible.
