After giving it some thought, you decide to change yourself back to how you were during the last match - still a hot vixen, but with less exaggerated features.
You tell the carnie as much, and after fiddling with various dials and buttons, he aims the gun at you and pulls the trigger, resulting in the same tingling feeling as before, but nothing else happens.
Confused, he tries to zap you again, even re-doing the settings, but aside from a slight tingle, nothing else happens.
"What the heck, did that thing finally break?" He changes the settings once more and points the gun at himself, but this time it actually works, and he grows a big, bushy beard.
"Alright, let's see if it's fixed now"
He points the gun at you without changing the settings and pulls the trigger. You shrink back, after all you don't want to be a fox with a human beard, but aside from the tingling, you still don't notice anything else happening.
"That's weird, don't think that's happened before. Well, time to get rid of that - "he zaps himself again, removing his beard, "and see what we can do about that."
After some more rummaging about, he hands you a choker with some coin-shaped disks on it.
"Here, wear this while you play your next round, this should collect extra data on what's going on with you. In the meantime, I'll go hit up the eggheads that made this and see if they can't figure out what's wrong with you."
He gestures for you to leave, but you have some concerns.
"Um, you don't happen to have a spare, um, F-cup...ish bra lying around here? I'm decent for now, but if I go running and jumping about in the arena again, I'll might as well tear off the rest of my clothes and go streaking for all the difference it makes."
"Sorry, lady, no clue, but go ask the lady from security that brought you to me, she's got a pretty good idea of where everything is - actually, I'll come along, they'll all need to know what the deal is with you anyway."
With those words, he puts his tools back down and leads you back to where you came from.
After you enter back into the main premises, he talks to a security guy, who then radios for the lady you were with before.
He then turns to you and says "Wait here, she'll be with you in a minute"
After that, they both walk off, the security guy returning to his job, while the other person goes back into the staff section, leaving you behind.
Luckily, business seems to be rather slow at the time, so you only feel a little bit awkward standing around with tattered clothes, one hasty motion away from flashing your huge tits at whoever happens to look in your general direction, but before you can get too uncomfortable about it, the security lady from before returns.
"Hey, I heard about what happened - too bad that the extra prize was a bust, but at least they're working on it. Regarding your decency, we had a 'freakshow'-style exhibit a few years back, which included a similarly gifted lady who eventually decided to zap herself back to a more reasonable size, so a colleague is asking around whether we still have her old stuff. It'll probably be some gaudy thing designed to look good on stage, but any support is better than none, and at least you'll get your ladies covered again."
While you talk, she leads you to a separate lounge where she tries to make some more small talk, but you're getting increasingly nervous about the prospect of having to stay like this, and returning home without anything to wear, so your answers are short and non-committal and you eventually fall into an uneasy silence.
Luckily, it doesn't take too long for someone else to come in with the underwear in question - a bra that looks like someone took two cereal bowls, flattened them out a bit and connected them with the smallest strings they could find, and panties that'd make a decent tent for a lawn gnome or two.
Both pieces of cloth are absolutely covered in sequins and glitter in several colours, but luckily none of them clash with your fur too badly, and after putting it on, you have to admit that you actually don't look too bad in that outfit, even if it doesn't quite go with the sensor-laden choker you put on earlier.
After testing your range of motion for a bit, you're finally ready to receive the other part of your winnings and sign up for your second, free round.
