I love to jo to pics of girls I know. I have since high school, when I was the yearbook photographer. In my job I do a lot of field work, often with girls from the office, and we're always taking pictures of everything we do. So I have a nice collection of sexy pics.
My current favorites are of a friend with beautiful firm big breasts and large prominent nipples. We were out in the field on a hot day in the fall, and she was down to her halter top and a soft thin bra that concealed little. The pictures show the shape of her breasts as if she were naked, and her nipples make shadows in the sun.
I also have some pictures of a friend topless and naked at Burning Man, and also of her friend there who has awesome floppy tits.
I've swapped pictures with an older woman, too. She loves to see pictures of my cock, especially cum shots, and her hubby takes nice pictures of her fingers slipped into her labia...mmmm.
And finally, just a picture--doesn't have to be sexy--will do it for me if the girl I know is sexy!
