You cross your fingers tighter as you watch a humanoid form take shape out of the glowing canine figure. The arms and legs stretch out, the muzzle retreats, and the tail shrinks back into the torso. Soon, just like before, the glow becomes so bright that you can't really make out the figure anymore. Then the light clears, and relief washes over you at the sight of a familiar human male sitting in the booth.
"Did that really just happen?" said the 28-year-old man as though waking up from a dream.
"You being a girl dog? Yeah, that was legit, man. This device totally works, just like we thought!"
Jonas hurriedly throws on his clothes and looks away from you, blushing silently. After he doesn't say anything for a while, you start getting worried that maybe something went wrong, after all. But he physically looks fine, and all the bio data on the screen looks to be within similar parameters to the original Jonas who went in.
"What's the matter, bro? You just made history, and we're gonna be rich!"
"You're not gonna tell anyone that happened, are you?" he said, jerking his head around face you with a panicked look on his face.
"Well, not any more or less than you would prefer, it can just stay between us now that we both know for sure that we can change people back and forth."
"Good, good. That was kinda embarrassing, wasn't it?" he said, looking down with a nervous grin.
"Ah, sorry," you say, putting one hand behind your head. "I guess I just got so caught up with you in the moment with you that I picked the most seemingly fun thing I could think of without thinking through whether it would actually be fun for you."
He looks at you and tries to speak reassuringly. "No, no, it, it was fun! You're a great dog walker. Ginny is really lucky. Still, though, I had a guy dog flirting with me, and I actually peed on a hydrant. I even needed you to--well, you know." He scratches his chin as though thinking about something. "I ate dog food, didn't I?"
"It was just one treat. And you didn't do anything that wasn't perfectly normal and expected! Well, for a man turned beagle, anyway. That's what makes this so great! We now have a power at our finger tips that people have wanted for centuries."
"I guess I really made a fool of myself, didn't I? If we're not friends anymore, I understand."
"What? Jonas! Surely, you've got to know I don't think less of you for doing dog stuff as a beagle. You were a great pet for like the half-hour you were one, but you've been a good friend since we were in third grade!"
"But you saw me naked..."
"Normal for a dog, and only for a few seconds in your human form. I saw far more scandalous things at that summer camp we went to."
"So we're...?"
"... still friends? Successful friends? Soon-to-be wealthy friends? Friends who just got to try something no other friends on Earth have done before?"
Jonas's anxious frown breaks into a smile. "It was pretty cool, wasn't it?" he says slyly.
"You know it!" you say with a grin. You wonder if it's too soon to ask him to try another transformation.
