Tethys and Nubium are quite the professionals. Well, they try to be. But occasionally, it's just that tiny bit too tempting to just sneak in a little bit of teasing in, and just completely loom over the other one while the other's at work.
Tethys here seems to have replaced the sun with her necklace when Nubium wasn't looking, which is going to make for a very interesting orbit for the planet he was working on... not that he minds. He really could get used to views like this!
