Accidentally wore my wife's panties

Last week, I had to run out and do an errand, and when I was getting dressed, I didn't turn on the lights and just grabbed what I thought were my pants and underwear off the bed. Well, turns out I accidentally grabbed and put on my wife's underwear instead of my own and then wore them all around town while I ran my errands. I got home and went to the bathroom and it wasn't until then that I realized. I thought it was funny so I told my wife because she was home by then. She laughed so hard, and then asked to see. I pulled down my pants and showed her, and she almost fell over laughing.

Now, I've never had a panty wearing fetish before. But they felt really good while I was wearing them, so good that I didn't even realize I had put them on accidentally. That combined with showing them to my wife, and feeling sort of humiliated while she laughed kinda turned me on.

So I guess now I've got a panty fetish.
