The Incident

You volunteered at a lab for experimental fursuits. A scientist takes you to a room with a few fur suits to choose from. Some are foxes, others are dogs, cat related (lions, house cats, tigers, etc) and others are custom ones which are not based on anything. They are in boxes, which box to you choose, but when you put it on, the suit seems to tighten, you cant get it off and it becomes your body, everything changes all they down to reshaped bones, new blood veins, nerves and even new muscles.
