I'm a single child so I always fantasize about growing up with an older sister, watching her grow, her taking care of me and playing with me. As she grows older and gets her urges, she starts to use me as a release and being too naive, I would play along with her.
As I start to get those urges myself, our dynamic would change but her, noticing it, would take care of it and explain it to me by using her body to demonstrate. I wish I could offer my first ejaculation to her!
