Any thinking on chitchat to my sis in the order of sex?

I totally trust my sis. I actually love her to extermination. I do talk to her almost periods. And she answers any interview I have. I do enjoy a book called whats stirring to my body book for girls. How can I show her this book with out race knowing that I have the book? My sister in fact has never said anything to anyone give or take a few what I have told her.
She have said that she knows everything from Sex the womanly body. Sounds like you own a really nice sister! I personally love that book, so perchance just donate the book on her desk or bed open to the page near the beginning of the sex chapter near a note dictum "Can we talk roughly this later?". She will read. And it is no big deal to own that book! Or just approach her near the book and say, "I enjoy some questions nearly this...".
Hope this helps, accurate luck!
Just ask her not to tell society about the book.
Just ask...
Just achieve her in a room by yourselves or when you two are alone within the house and show her. Tell her not to tell not a soul. It's that simple.
