You don't have long to dwell on your double's reaction, however, because an all-too-familiar sensation makes itself felt. This time, instead of being localized, the itch has spread all over your body like wildfire. You are in agony, and judging by the contortions of the other you, he is feeling it as well. You wish you could make it go away by ignoring it, but you have a pretty good idea what is happening.
Your suspicions are confirmed by watching the change come over your counterpart. Although both of you are wearing clothing that provides relatively good coverage, you can see a soft down of fur make its way across the back of his hands, his neck, and even parts of his face. What you can see of your own body leads you to believe the exact same is happening to you. Your attention is drawn by your double's movement.
"What are you doing?" you cry as he starts to pull of his hoodie.
"We have fur now, too much clothing isn't exactly going to be comfortable," he says matter-of-factly, and continues to pull it up.
"We can't go outside looking like this!" you nearly shout. "We'll be carted off to some quarantine facility somewhere if anyone sees us with tails and dog ears, not to mention fur! Leave it on!"
The other you considers for a moment, and you get the feeling that while he is not happy about it, he knows you are right. Of course he knows you are right, he's you, and you know you are right, right?
"Look, let's get out of here and get home before something else changes. At least if we're at home no one can see us, and we can figure out a way out of this mess," you state convincingly. The other you pauses, but nods. Having seen no one in the shop the entire time, you hope that maybe getting away from the magic of the shop will slow down whatever changes are yet to occur. You put on your sunglasses and fake nose, and pull up your hood to cover your new ears. You pull the back of your hoodie down over your rear, and stick your tail up inside the hoodie, praying that it doesn't decide to wag at an inopportune moment. The other you reluctantly follows suit. While you make an odd pair, at least you're mostly covered up. You plan to keep your furry hands in your pockets as much as possible. Thankfully, it is getting darker outside, and the low light should help.
Amazingly, both you's make it hope with little to no trouble, although you do manage to garner a few stares, and most dogs passing by seemed to be more interested in both of you than would be normal. Upon entering, you quickly pull all the blinds to ensure no one can see into your house, and eventually, your doppleganger helps. Finally, you remove your glasses and fake nose and plop down on the couch. Certain that there can be no further objections, the other you pulls of his hoodie and his t-shirt, revealing that his torso and arms are also entirely covered in fur, albeit short fur, and from the looks of it, his hair is slowly becoming more fur-like as well. You don't even bother to inspect yourself at this point, certain that you are suffering the same fate. Thankfully, the changes seem to be slowing, and you hope they are nearing their end, although you are not sure what to do when they do end.
"I need a shower," you say out loud, thinking that will help you relax a bit at least.
"Good idea!" the other you pipes up. "Let's go!"
"What, both of us?" you ask, incredulous.
"Well, we're both probably going to need help figuring out how to wash all this fur," he replies, "not to mention the tails. Besides, we are one person. Why not?" It sounds a bit weird, but he does make a good point, and you figure it's like bathing with a brother.
In the shower you confirm one last detail you were hoping to avoid thinking about. Your privates, as well as that of your twin, have become rather canine as well, even sporting a furry sheath. You are mortified, although your double seems to take it in stride. The other you shakes himself off in the shower, but you get out and dry yourself carefully, and convince him to do the same. Although he obliges you, he then wanders around the house with no clothes on.
"Why the heck are you walking around buck-naked?" you ask irritatedly.
"What's the problem?" he asks nonchalantly. "We've got fur, it's not like you can see skin or my privates or something."
"Whatever," you reply, "at least put some shorts on. What if somebody else sees you?" You throw him a pair of boxers, and although he pouts a bit, your double obliges you.
"Who's going to see me?" he asks grumpily. "It's not like someone's gonna come around knocking in the middle of the night..."
As if to punctuate his words, at that moment, you both hear the doorbell. You both freeze and stare at each other as the doorbell rings again.
"Are you there? C'mon, I see the lights on, lemme in!" you both hear a female voice say. It's your girlfriend, Sheila! With all the excitement, you forgot she was coming over tonight! What do you do now?
While you are pondering a course of action, your double happily yips "It's Sheila!" and bounds over to the door without a thought. Perhaps he got more of the dog brains, you think to yourself for a split second before you run frantically toward him and the door. When you reach it, you...
