Here is how I started with my wife.
Not long after we got married she found some of my old porn stash and said she could never do that in case friends or family found out. So I asked if I could take some pictures for my own collection and she was surprisingly happy to oblige as long as I never ever showed anyone else. She had a very conservative upbringing so I was not expecting her answer but she admitted that she had flashed a few times when she was in her late teens and it turned her on but she will never do it if anyone who knows her could find out. I did remember at that point that when I first got her into bed, she was pretty keen and turned on to show off to me.
I know it is not right that even though I swore I would never post her pictures online, I did post a few close up pussy pictures in one of those pussy rating sites. She scored very highly and one night when we had both had a drink or two, I made mention that 100s of men think she has a lovely pussy, then I showed her, her pictures online. She was a bit shocked at first but then started reading the comments and really got off on it. I asked if I could take a few pictures if I hid her face and name and she was more than keen, she quickly got some clothes together and organised a place for our first photo session.
She started off just dressed sexy, then started peeling off clothes. I was really surprised that my new wife was so into it after her upbringing and otherwise conservative nature. As she got down to her bra and panties I reminded her that if 1000s of men will soon see her naked if she continues to strip. She was excited to get her tits out and pose a bit and asked if I think other men would like her boobs. When the panties came off, I saw that she really was getting wet and she admitted that it turned her on that soon 1000s of men will soon be checking out her pussy.
After the photo session, she was extremely turned on, so I had to sort that out before going through the photos and sorting out together which ones will and wont go online. We didnt know about this website back then so we posted her first session on another site. As I hit the send button I reminded her that now her naked body would be on the internet for anyone to enjoy. She surprised my by keeping checking the site to see how many views and comments were on there so in the end was just as into it as I was. That was over a dozen years ago and we have changed user names and come and gone a few times and slowed down a little, but every few months or so decide to do just one more photo session if the time and place is just right.
