Putting up lights in the dark, around the fenced off area in the garden of the house. Two friends doing this probably in the snow. You can base it off your own home or someone elses, the main thing is to get across the enjoyment of putting up this stuff together.

To make it lewder, there may have been an accident during putting up the decorations and maybe one person went inside of another~

Alternatively it could be decorating someone up like you would a house!

Enjoy~
