I had sex with my older sisters

I am a 14 year old boy who just had sex with his 16 year old sister. My parents were going away for the weekend so they decided to leave me with my sister. My sister is very hot and I have fantasized about having sex with her for a long time. Whenever I saw her I would get really turned on and I would always stare at her. My sister found out how I felt about her and she told me that she had been fantasizing about me for a long time as well. My parents left on Friday and me and my sister were talking in the living room. I decided to make my move so I just walked over to her and I kissed her. She kissed me back passionately and then we started touching each other. We decided to go into my room and we had sex. I loved it and my sister said it was better than having sex with her boyfriend. We had sex again on Saturday and Sunday. I felt extremely bad and I loved my sister and I thought that it was wrong. Then I read an article on this website and it made me feel better.
