it is my experience that if you have a camera and ask properly most ladies will allow you to photograph them
it is also my experience that a high percentage will allow you to take sexy pics
it is also my experience that, if you handel the situation right, will disrobe and take rather more explicit pictures of them.
i know one or two will afterwards regret the action and ask you to press delete and as a gentleman i always, without exception do. but as for the rest, i am always amazed what a large collection of women, undressed in various states of touching themselves there are.
