Is it normal to have sexual feelings for my cousin

Ok this happened last year. I was at my cousins house one weekend and we were all having a good time, like usual. It was getting late so my cousin ( let's call him Isaiah )suggested that we go and watch a movie. I agreed and so did my other cousin (let's call her tori). We went to his room watched the movie and fell asleep. Later that morning at..3:00 I woke up to tori accidentaly wrapping her arm around me. I looked at her sleeping. Watching her perfect body and chest moving up an down. I got turned on. Now at this point I reach my hand out not wanting to wake her bro. And touched her Breast. I then got worried and went back to sleep. Is it normal. I'm not a perv by the way and I wish I hadn't cuz I started acting weird around her the next day but she didn't know why. And I would never do anything to her. I love her like a sister and I've never done it again. But I still have this feeling for her. Is it normal?
