I've decided on my course of action... I definitely want him to see the pics, especially if he will enjoy them and not be weirded out by them. I'm going to tell my wife about her mistake at the beginning of next week when due to work and weekend plans it will be at least a couple weeks before we will have time to go swap drives. This way I can see her reaction and what she wants to do and decide what I'll say to him. I should be able to feel out if he has seen any pics or not and possibly drop hints as to the content on the drive. This will give him plenty of time to snoop and result in lots of nervous excitement for me and wifey since we will have awhile to wonder if he is seeing her in all her glory. Should be a fun few weeks...
