Glee Animals

Of some reason all the glee kids and Mr. Shue has been under a spell after they won, every time they hug someone from the other gender they turn into different animals. The bad thing is that when they turn back their clothes are gone.

(I now that people don't have to be a specific gender, but I got this idea from another story)
(It is also going to be a bit of klaine, Brittana, finchel and all the other couples)
