No sooner had the words "white-tail deer" left your mouth than you felt a stabbing sensation down in the back of your pants. Something was very different down there. There was a twitching feeling and also a tight, constricted feeling. You pulled down the back of your pants and realized immediately that this machine really works, because you could now see the deer tail that was sticking out above your butt. You could see the tan fur on top of it and the classic bushy white fur on its underside. You could feel the tail actually attached to you, and you could feel it move when it twitched back and forth. Quickly you looked around to make sure no one was looking, then you pulled your pants up and decided you might need some privacy.
You walked into the public restroom feeling both anxious and elated. You could barely believe it was real. You were getting a tingly feeling around your waist, and you wondered if there had been any more changes hidden inside your clothes. No sooner had you locked the stall door than you took your pants all the way off. You practiced moving your tail again, watching it whip back and forth like a deer's does. Then you pulled up your shirt. Sure enough, you were starting to grow fur around your abdomen all the way around your back, too. It was a pretty white color on your underbelly and tan everywhere else. You took your shirt off too and watched the fur keep growing up your chest and down your legs. Suddenly you felt a pulling on your ears and reached up to touch them. Wow these things were huge: powerful, too, you realized when they jerked sideways for the first time. You realized you could now hear pretty much everything now, such as water settling in the pipes and humans outside, some arguing and some just having a mild chat. Everything was so loud here now! Your heart starting racing and your tail perked up in a startled-deer expression. You kept yourself under control though and just focused on the change. You took your shoes off when your feet started lengthening. The fur kept spreading, and before long your toenails had grown out into long cloven hoofs that clicked softly on the tile floor.
You looked back at the stall door and realized that you might be stuck in here. You decided to open it while you still had hands. Whew, that was close. You really hoped no one would come in and see you changing, but there was no way you'd fit in the stall anyway after you became deer-sized. You twitched your new ears around listening to every outside voice or pair of footsteps while your arms changed. The hands lengthened out and fused and grew hooves like your back pair. Standing up on all fours with your front half outside the stall, you felt the size changes start. You got bigger and heavier but felt lighter and more nimble because your powerful new muscles were growing in. At last your felt the fur spread up your head and over those huge ears of yours. When it reached your face your felt your mouth and nose stretch forward and push your eyes apart. This pushed you overboard and you snorted loudly. You were suddenly seeing almost all the way around yourself but everything seemed blurry and the colors were strange and somewhat muted. You were also being powerfully hint by all of the human smells coming from every direction. You got extremely dizzy and just stood there in shock for a moment.
A human voice emerged from outside the door. Your turn your left ear back slightly to hear it.
"What was that noise?" someone asked. "I don't know" said someone else. The sound of shoes coming toward the bathroom filled the room. You knew they heard you snorting and were about to find a deer standing in the bathroom. You were amazed and a bit overwhelmed, but now you just felt kind of silly for having just turned yourself into a deer in a public restroom.
