To be honest, having seen the collage I thought I had her in my albums somewhere, but have checked the Shy Girls albums and it seems I don't. However, I will collage her and post her in one of them, and also on the Before and Voyeur thread later tonight just to cheer you up for Xmas!
Depends what your wife looks like. I used to get pics from Hammy and Image Fap, and occasionally the Moth less site, but it also depends what pops up with image search on Yandex.
