Your favorite animals are cows and bulls. You don't kmow why but you've just always liked them. So you grab the large bull mask from the pile and set it off to the side as you pick up the other ones. Soon you finish, you grab the mask and walk up to mirror. You examine the mask. It has realistic features, horns and is covered in black fur. It looks real but it's so big that it reminds you more of a mascots head than an actual costume. Either way it looks very realistic feels like a real animal head. You lift it up and put it on. You look good in it, you consider saving it for halloween and try to make a complete costume with it. After a minute or two you decide you've had your fun and lift your hands to your head to remove the mask, it won't budge. You keep pulling and pulling, and start to get extreamly frustrated. Suddenly you see black fur crawl done from the mask. You pull at it and find that it's attached to you. Suddenly you double over in pain as you feel your muscles exapanding. It's worse than anything you have felt. You black out from the pain. You wake up hours later in a daze. It takes you a sec to remember the mask. You quickly look at the mirror to see your transformation. You are an extreamly muscular, 7ft anthro bull covered in black fur. You look like how you'd imagine a minotaur to look like, except with human feet and being fully covered in fur. Your clothes have given way to your muscle, revealing a massive cock. You try to think up a plan, but just before your able to you hear footsteps comming down the stairs.
