Surprize for husband

My friend kindly asked me to visit. I raised my eyebrows in surprise: “You mean… just a casual visit?”
“Yes,” she whispered, “it holds a special surprise for you. But first, please close your eyes!”
Obeying her request, I opened the door by touch and took a few steps inside.
“You may now open your eyes!” my friend’s voice announced.
The first sight that greeted me was her bare, radiant backside. Then, I heard her heartfelt words: “My husband has instructed me to bring you joy today!”
