The difference is that you have here 2 adult guys, adult photographer and... 15 year old girl. Don't you think it may be difficult for a 15-year-old to suddenly say "NO" when photos are becoming bit to spicy? And even if she liked the photoset she is still underaged and cannot be taken for granted, especially with such a delicate issue. From her interviews, instagram streams it's clearly visible that she not always speaks like an adult, and has childish moments as well- because she is still psychically a kid! That's why adults should take care of her. And I really have the feeling situation was quitevopposite there.
