You hope to get home without being changed, so you can try to figure this out, so hide your gloved hand in your pocking and quickly start walking home. For a while, you get lucky, and don't run into anyone. You get within a couple blocks of your home, and you start to think maybe things are going to turn out okay. Then you hear something that screws up all your plans.
"Who has the cutest little doggy ears? You do! Yes you do!"
You freeze, turning around. Behind you, there was someone petting their dog and talking to them in baby talk. They'd been crouched down so you hadn't seen them. They aren't even looking at you, and you hope that maybe since they didn't say it to YOU, the glove won't activate, but then a bit of latex breaks off the glove and slips under your clothes. You feel it crawling up your body, and you try to grab it, but it slips between your fingers and ends up on top of your head. When you reach up you feel two small, floppy latex dog ears peeking over the edge of your hair. You try to yank them off but they're firmly attached, and you only hurt your head in the process. Embarrassed, you duck your head and run for home while you try to come up with a way to fix this. You can't get the ears off yourself, but maybe if someone else said "human ears", you would turn back to normal. You'll have to get home to call a friend over and hope you can convince them...
Lost in thought, you aren't looking where you're going, and you run directly into your next-door neighbor Curtis. You've talked a few times and he seems nice, if a little gruff, but you'd never gotten to know him beyond that. He knows you well enough to know you don't usually have dog ears, though, and he shoots you a confused look as you apologize for running into him.
"No problem. Say, you uh...feeling okay? What's with the costume?"
You try to equivocate your way out of this, but your nervous attempts to change the subject only makes Curtis more suspicious, and he insists you tell him what's going on. Maybe if Curtis won't take no for an answer, he'll be willing to help? Not sure what else to do, everything spills out of you in a rush: the glove, how it's stuck to you, and what it can do. Then you ask him to change you back. Curtis just gives a blank stare, even more confused, and there's a long, awkward pause before he replies.
"That's...quite a story. I'll be honest, it's pretty hard to believe. Like, I could just say 'pig head' and you'd start snorting all over the..."
As soon as he says "pig head", you panic and try to cover up his mouth, but it's too late. You feel the dog ears on your head melt away, covering your face, and for a moment you can't see anything. The latex is heavy, and it feels like it's forming a thick, over-sized mask over your whole head. Then you can see again, and the first thing you see is a snout sticking out where your nose should be. You reach up and feel around your big snout, and although the sensation of your touch is dulled through the layers of latex covering it, you can still feel sensation from the snout like it's your own nose. You take in a deep breath and feel the pig nostrils expand, letting out a soft snorting noise. You feel around the rest of your head. Your ears are still tiny, floppy, and at the top of your head, a lot like the dog ears were, but everything else about your head has changed Your hair is gone, and your face is fat and covered in latex. You reach down to your neck where the latex stops and try to lift the pig mask off your head, but there's no seam, the mask melds into your skin. You try to beg Curtis to change you back, but you cover your mouth in shock when all that comes out is a jumble of squeals and grunts.
This display breaks Curtis out of his stunned silence, and he starts to laugh. You cover your head with your arms, embarrassed to be seen, and Curtis calms himself down. "Well, I guess I'm convinced. How about you come inside and we get this sorted out?"
