While my wife was out Black Friday shopping with MY credit card, was it wrong to have the EF over for a photo?

in front of the Christmas tree? My EF (Emotional Friend, 21, female, 100% platonic, likes to go commando) wanted a shot of us in front of a Christmas tree for her cell phone wallpaper and to send to all her friends. It only took an hour or so. As a joke, she wanted me in just boxers and a Santa hat and she sat on my lap in a half-shirt jersey, hot pink, No. 69 with the word "easy" written above it. The wife never knew, and it helped me tolerate the $789 she'd spent much better.
