You feel an odd sensation from your backside, and a sudden chill alerts you that something is wrong with your pants. You look back over your shoulder to see a small, neat, round hole just above the seat of your pants, through both your trousers and your boxers. Wondering if the Game Master was planning on embarrassing you by making you walk around like that, you look back suspiciously at the hooded figure. However, just as you note his sly grin, you feel a strange tugging near the hole in your pants and the weird feeling that something plugged up the hole. You look over your shoulder again to see hair...no...fur poking out of the hole, and growing longer. At first, you can't make sense of what is happening, but as the fur extends and begins to twitch, it finally dawns on you that this is your punishment. You glower at the Game Master for a second, then the large mirror, which still covers the opposite wall, catches your eye, just as the feeling in your backside subsides.
You are standing 90 degrees from the mirror, and, looking to the side, your attention is grabbed by a bit of motion along the back of your legs. Hanging from between your coattials, where the hole in your pants was a moment ago, and twitching slightly, is a knee-length luxuriously-furry dog-like tail, the color of the fur matching your hair exactly. At first, you wonder if it is some illusion, but as you step to turn a bit away from the mirror to see better, you feel your trouser legs brushing against the fur of the tail through the tail. You have been through so much insanity in the space of just a few hours that all you can do is stare numbly.
"Just so you don't forget again who the 'master' is here," the Game Master chuckled. You can't even bring yourself to respond.
"Well, now that that's taken care of, why don't you tidy up after our customers," he continued, indicating the empty glasses and vial, and dismissing the mirror with a gesture. "Then you can update the inventory. That should be enough for the first day."
Not even bothering to resist anymore, you begin to clean up as the Game Master returns to tinkering with his products. After all, no one will recognize you, so what does it matter if you have a dog tail, or anything more ridiculous? Although the sensation of muscles and nerves from your new appendage while you walk around is a bit disconcerting, you figure it can't be much worse than having been changed into a guy. You finish up your duties and, dismissed by the Game Master, you return to the changing room to take off the uniform. Despite your irritation at being gender-swapped, as you remove the articles of clothing, you can't help but admire your male form's physique. Although not extremely muscular, you note the body is lean and wiry, suggesting subtle strength and stamina. While masculine, the face and features are reminiscent of your own, as through you were seeing a male relative. You finally remove everything but the trousers and boxers, your tail still swaying freely behind you. Carefully, you pull down and step out of the trousers, then the boxers, threading the tail through the hole in each as you pull it down. Once you step out of the boxers, you feel the same dizzying sensation you had experienced when donning the uniform, and close your eyes as you grasp the wall for a moment. When you open your eyes again, a familiar face stares back at you from the mirror.
Glad to be back to your female high-school self, you exhale, relieved. However, your breath catches in your throat as you note something soft brushing up against your legs. Turning and looking back over your shoulder at the mirror, you register to your utter shock and disbelief that you still have a tail . For some reason, you had assumed the tail was part of the uniform, and once you removed the butler outfit, you would be back to normal. However, you come to the sickening realization that the Game Master never indicated that this was the case. You nearly run out of the changing room stark naked to confront the Game Master, but what reason you have left makes you aware enough that you remember you are in the mall, and there is no telling who might see you naked and tailed. You hurriedly dress yourself, but realize that, wearing a skirt, you have no way to truly hide your tail. You cannot even put your underwear on, as you don't want to cut a hole in your panties, and there is no way you can pull them over the tail. You consider putting the boxers back on, but as they are part of the magician's uniform, you can't risk being changed back into a guy. In the end, you tie your jacket around your waist over your skirt in hopes that it helps provide better coverage, and stride out commando to face the Game Master.
"I'm done now, so get rid of the tail," you demand.
"Why would I do that?" the Game Master responded evenly, without even bothering to look up. "Besides, you heard what I told the other girls, nothing can be changed for a week."
"A week??!!" you squeak out, dumbfounded. Worrying about going home looking like this becomes the least of your worries. You have four more days of school left this week! Although you are too mortified to notice, in truth you needn't worry any more about hiding your tail. Due to your evident distress, it is quite firmly tucked between your legs.
Through the fog of bewilderment, you decide...
