You have always wanted to be the oldest in your family.. but being the younger brother to a perfect successful sexy sister has not always been fun.. you are thinking about how you wish you were in your older sisters position and you pick up her hair brush .. using it and then going to bed dreaming about what you wish could be. But when you wake up and you are in your olde sisters body... this is not exactly what you meant by switching positions with her.... but after a few minutes you realize this is the best thing that ever happened to you... your female body feeling better then your male body ever did.. your hormones take over and you play wth your new body.
