I went to my brother in law's 60th birthday party, but I don't see that side of the family much since my wife passed 9 years ago. About the only one I talked to was my 28 yo niece. She told me she wanted to go for a motorcycle ride and the next day we went for a ride. When I left she gave me a passionate kiss and wants to spend a weekend at my beach house. I am thinking about fucking her as we are not related by blood. Is this wrong?
