My first thought was, "She looks pretty enough, but no, not even with somebody else's xxxx..."
As my Sainted Mother used to say, "You don't know where that's been..."
Decades ago, my husband and I were sitting on a ship on the Amazon watching the other "gringo" passengers load. One of the last passengers was a pretty young woman, scantily dressed, alone, and as she came up the gang plank, every man turned his head to look and just as quickly, once they saw that she was bare footed and had sores on her feet and legs, they looked away. It was pretty amazing to watch.
