Andy did not understand that being gunged was supposed to be a punishment for her sloppy work so I had to take a seat next to her under the tank and show her how it's done.Andy was still in her undies and I didn't bother to change out of my tight black work dress.  We put our heads together to see what ideas we could come up with and yanked on the chain to release the gunge.  Lots of gloopy, white, orange and purple gunge slimed us both from head to toe, and our feet slid around in the puddle of gunge from Andy's previous gungings.  Lots of giggling from both of us and it seems the gunge tank isn't a punishment at all – it's great!
