Wow... Today, I was cleaning out my office and ran across a number of CD's with pictures on them. I decided to transfer them to my hard drive and a came across a disc that was over 20 years old. The disc had pictures of my ex-girlfriend (we still keep in touch). I went to visit her when she was in college. I talked her into modeling for me and we went through her lingerie drawer to pick out some of her favorites. There are pics of her pulling off her bra, playing with her nipples and showing her bush. Plus the one where she was sucking my cock. I just HAD to start jerking as I looked at her gorgeous body and her sexy poses. I think I want her now more than ever. If you have pics of your ex, keep them. You won't regret it.
My last two friends, a GF and an FWB, both asked me to photograph and video them. I've intimately photographed quite a few women and a couple over the years. The two closer friends were totally sexually open. One said afterwards that I should keep them until I was finished with them by which she clarified as meaning as long as I want. She wanted me to have stuff to play with. The other said when we split that she didn't mind if I keep them. Unusually for me, I've never tired of them.
It's great because you (and I) were part of that creation. It's not just random pictures of girls naked. We had input on the outfits and the poses. My ex was the beauty, but due to her shy demeanor, the poses were mostly my ideas. I would never part with the images.
In memory, I have "greatest hits" moments that I often think of. Even if they're decades old they still get me over the top.
