We went on a little ski holiday over the winter break and rented a condo right beside a pathway to the ski hill.
We noticed several skiers walking by and, with a little coaxing, Mrs Smith stripped and when the next guy walked by, she just stood there completely naked and let him get a good look at her.
He pulled out his phone and took a picture of her before eventually carrying on his way.
It was such a turn on that we had sex right there in front of the window for all to see...
