My sister read that book. I don’t know if I knew then what took place in the book, but I did by my early 20’s and wondered if she was open to or had fantasies about our relationship evolving to such an intimate level.When I found a copy of my mother's Flowers in the Attic. I was just old enough to understand what was going on as well as know it probably shouldn't. I think I read it several times that summer while learning so many different ways to masturbate.
