This is inspired by a clip from an old Spanish gameshow I saw on Youtube. In their version the contestant wore a suit that would have kept the mess out, mainly, and a swimming cap and goggles. I felt there could be improvements.

Friday Night Festival was a big new late evening entertainment show. It had a mix of celebrity interviews, music, comedy skits and audience participation for prizes. Some of this was quizzes, but it had made a name for itself with spectacular and often messy challenges.
"Ok, before Adam and the Hotshots play a song off their new album into the break, we need a player for the challenge after" announced Helen, the presenter. "Many of you have been brave enough to put yourself forward despite knowing nothing about the prize or what's in store for you. Over to Nicki, who's somewhere in the audience, to tell us who'll be playing."

The studio lights had been darkened. It wasn't clear where Nicki was, especially when stage hands in positions in all the aisles. Suddenly two spotlights came on,illuminating Nicki and one audience member. "Our plucky contestant is Susannah Clarke!" The cameras zoomed in on a shocked looking brunette. "Susannah, come join me" said Nicki. The woman stood up and shuffled along the row. She was wearing jeans and a turtleneck sweater, quite a conservative if stylish outfit. "Tell us a little about yourself" said Nicki, offering her the microphone.
"I'm Susannah but my mates call me Susie, I'm 32, I'm a bank manager from Aidrie and I think my girlfriend must have filled out the entry for me as I definitely didn't." The camera zoomed in on a woman sat next to an empty seat, who waved and smiled wickedly. "I wouldn't usually do this sort of thing, but she's been insistent on getting me out of my comfort zone."
"So you'll play the game then? No matter what it is, and no matter what the outfit? You have seen our games yes?" asked Nicki. "I'm apprehensive, but yes. Let's go for it. I'll show Martha I'm still adventurous. I'm absolutely getting her back for this when I get home though!" replied Susie.
"Great stuff" said Helen from the studio floor. "Nicki, take her off to get ready, we'll see her after the break. Now, Adam and the Hotshots with their new one "Piece of Cake".

After the break, the lights came up on Helen and Nicki wearing chefs white, with Susie in a bath robe. They were stood next to the base of a vast tiered cake stretching towards the studio ceiling. A faint net could be seen stretching out from near the top. "With Adam singing about cake, our production team came up with a great idea" introduced Helen. "Our Susie here is going to be our decoration on the top of the cake. Now, it wouldn't be our style to just lift her up, and it wouldn't be safe to scramble up the outside. Thankfully we've left a route spiralling up inside, though it's a little tight in places"

"That's right Helen" said Nicki, "she'll have three minutes to work her way up and pull the rope hanging from above the cake. And she'll definitely want to make it in time, isn't that right?"
"Right. If she makes it time, she can win a two week holiday for two in the south of France, including a special patisserie workshop with a top chef." The audience were shown a short montage as Helen described the prize and "oooh"-ed appreciatively. "She'll also get £2000 in cash. How does that sound Susie?"
"It sounds amazing Helen, but I've seen this show before and I know it's not that simple."
"Indeed" interjected Nicki. Don't make it in time? The clothes you came in are being put in a shredder. You won't even get a shower. We are generous though, we'll give you a Friday Night Festival overall to make sure you don't make a mess." On screen a clear plastic suit, with a hood, was shown on a mannequin, with the show logo printed on the rear. Susie could be seen mouthing "oh shit". She knew she should have read the waiver forms more carefully.
"So thats's the stakes. Remember, even if doesn't look like it, there's always a way forward" said Helen. "Now, let's see what you're wearing." With the excitement over-ruling her trepidation, Susie shrugged off the bathrobe and did a twirl. She was wearing a one piece white swimsuit with short legs, but with a low cut front showing off her cleavage. On the belly was printed the show logo, and it was cut low at the rear. "Very nice, stylish. Are you ready?"
"As ready as I'll ever be Helen" said Susie. Nickie led her to the low entrance in the base of the cake.
"OK Susie, on the count of three. Three, two one GO!" shouted Helen. Susie wasted no time, ducking into the dark entrance. She couldn't quite stand up, but there was enough room to scuttle forward and round the bend into total darkness. She recoiled as she touched the padded walls, which were slick with slime- her horrified face was clear on the nightvision cameras inside. She plowed on though, finding the floor sloping up. Feeling ahead of her, she suddenly felt a dead end? But she'd been told there was always a way forward. She felt the wall in front and it felt like cake? She heard Helen outside shouting advice. "Just run at it!"

So she did. Arms stretched out in front, she ran at the cake wall. As her hands ripped open a hole, she tripped and went flying forwards into a well lit chamber, landing face first in a giant iced sheetcake. At least that had cushioned her fall, though the force had sent lumps of cake down inside the front of her suit. But she was aware of the clock counting down, so no time to worry about that. She wiped cake out of her face and looked forward. There was a step up, into a lower passage. She climbed into it, and found that she had to proceed on hands and knees. As she started up, a flow started down the floor of the spiralling crawl space. "Cake batter" she heard Helen yell, "we didn't get it fully cooked it seems."
It was ok for now though, but this passage again wasn't lit and she was soon far enough round that the light vanished. It sloped up more steeply, but she found hand holds.
"You're doing great" Nicki called out encouragement to her, "two minutes." Helon had no idea though how far up she'd risen although the bend in the passage was now tighter. The floor flattened out and even went down a bit. She had to wade forward through the batter, still unable to see. Quickly it was up to her body, and the open front of the suit sent it coursing inside. She banged her head against a wall. "Always a way forward eh?" she said, mainly to herself. She felt out in front oof her and sure enough the wall only came down to the surface of the batter. She felt under it and couldn't reach the surface.
"Keep going, you're over halfway and you've still got one minute thirty" came Helen's voice from a speaker in the passage. "Ok" thought Susie, "they're not trying to kill you". She found a handhold on the bottom, took a deep breath and dived into the flooded passage. This forced the batter through her suit and into her sensitive areas, but she didn't care for now. She grabbed another handhold, then another, hauling herself forward and a couple of seconds later felt space above her head. She erupted into the light, her auburn hair vanished under the brown of the chocolate cake mix.
She scrabbled out of the batter and was able to stand up into a crouch. Round a tighter bend now was an even lower passage set into the wall. She could see this was glistening with jam. Figuring she couldn't get messier now she took a run and dived into the darkness.
"Wow Susie you're doing great!" exclaimed Nicki, "we were not expecting you to jump into that."
Despite all the batter she could feel the stickiness of the jam as she commando crawled through the tunnel. As she reached the end her arms, legs and tits were sticky and batter was slopping around inside her suit. The end was a tight squeeze between two rollers that deposited her into a vat of whipped cream. "One minute, you're nearly there" she heard muffled through the slop. Finding which was up she managed to stand, and found she could stand up straight. Wiping away the combined goop from her eyes she looked up at a bright light shining in a hole above her. A ladder was cut into one wall and she started climbing. "Thirty seconds" came the insistent call from Helen, but Susie was fine. She reached the top, pulled herself onto the platform, a white blob monster with remnants of red jam and brown batter visible. She reached up as the audience started a countdown from ten, and on seven grabbed the rop above her and pulled hard, looking up as she did. Despite everything so far she was surprised when she was met with a powerful jet of bright pink frosting that blasted her in the face. It jetted down between her tits and filled her suit to bulging. She tipped her head forward and it rushed in the back of her suit and into her crack. It was so all encompassing that she barely noticed the forewarks going off and the cheering of the audience. She sank to her knees and threw her head back. This allowed the flow to push down her front again, and the feeling of the pressure at her private parts was not unpleasant. She filed that away for later.

The flow stopped. "Congratulations Susie, you win the big prize" announced Helen, to yet more cheering. "Come on down so we can speak to you. There's a slide." Indeed there was. It hadn't been obvious until now, but wrapping the cake was a spiral slide. In a rush of delirium, Susie threw herself headfirst down it. The frosting provided ample lubrication and flew down. There was one final surprise, with the slide stopping two metres from the floor where a pool of cake batter swallowed her up . She managed to find up, and stagehand helped her out.

Nicki and Helen came over to her, but neither wanted to get to close. "Wow Susie, that was awesome. How do you feel?" asked Helen, holding a microphone on a pole. "Absolutely ecstatic. That was so much fun! Winning the big prize? Brilliant! Thanks to Martha for putting me up to this, that was life changing. Love you babe!" She waved to the audience, and the camera picked out Martha waving back, looking delighted. "I think I might have a few things to try with you!" Martha blushed at this.
"Well then" Nicki interjected, "we hope you enjoy your holiday together. The good news is that as well as winning the prize, your clothes are safe and our showers are excellent. We've even got a stylist on hand to help wash everything out of your hair."
"That might take some time, especially that jam" said Helen. "You better head off. Our crew will clean up the set, and we'll see the audience after the interval for more fun on Friday Night Festival!"
