Trying to seduce my cousin

Me and my cousin Vanessa have been close for a while and I felt like we always have had sort of a sexual tense in between us ever since we got to high school. We would always cuddle together at family parties and she would always try to be touchy in any way when ever we would sit together. I’ve never really tried to make a move because she is pretty innocent in a way but I would slap her ass when nobody was around, brush up against her, laying on her warm breast when no one was around,and long tight hugs of course but nothing too much that would alarm her that I’m trying to make love to my older cousin.
