I Saw Pictures Of My Friends Wife Topless

It was actually once of my wife's friends, many years ago. Being in IT, people often asked for my help with their computers. I could usually fix their issue in a few minutes at their home, other times I needed to bring it to my home to fix.
In this case I had to replace a hard drive, but managed to recover all their data. Once their PC was functioning properly it was returned to them. I waited a few weeks to see if they reported missing anything before deleting the backup I saved. Before deleting I snooped and found a folder with several images of my wife's friend posing topless. While I shouldn't have snooped, I did. I also kept the images when I deleted the remainder of their data.
