Prologue

I relaxed back into my chair as the private instant messaging conversation between the two girls continued on my screen. I stretched my arms and then reached for some popcorn. If Aika didn’t want me reading her private conversations, she probably should have a better Facebook password than “rosiebff”.

While I’d hacked my way into several people’s internet accounts before, so far Aika was the only person I’d targeted who went to the same university as me. The thrill of knowing her personally was getting me very excited, in more ways than one. I quietly hoped that I might stumble across some naughty or embarrassing secrets, because let's be honest, most people have dirt that can be found on their internet footprint. But I had no idea quite how delicious the blackmail material I was about to stumble across would be. Looking back on that day, it must have been the luckiest day of my life. Because as it turned out, as I connected in, Aika and Rosie were just beginning a rare fierce argument.

“I can’t believe you literally STOLE MY BOYFRIEND! Who does that to their bff?!?!”

Wow, a strong opener from Rosie. This was going to be good.

“Err, in what universe was Reese your boyfriend? You did him twice. Weeks ago…”

Aika wasn’t backing down from this one. Sparks were going to fly, and they had no idea there was a third party watching and logging their chat.

“I was falling for him, you know that! Now I know the reason he’s been distant is that my ‘friend’ was seducing him behind my back!”

“Girl, you scared him away. He never even considered you his girlfriend, just someone he was banging. There was nothing to steal. Quit being a baby about it, it’s not a big deal.”

“I AM NOT BEING A BABY! You’re being the baby here, you're not even grown up enough to admit when you’ve snubbed your best friend!”

“Oh my god, you’re literally crying as you type aren’t you? You can’t even reign in your emotions for two minutes to look at things logically. And you’re trying to call me the baby? Grow up, kid.”

“I’m not the one who wet my bed until I was fourteen!”

“How dare you try and throw that in my face! I told you that in confidence, you know how sensitive I am about that!”

“Well you don’t seem to care about how upset I am, Baby Bedwetter!”

“Screw you! I’m not the one who wore diapers as an adult, for SEX PLAY!”

“Hey I only did that three times, and it was Dave’s request, not my idea! That doesn’t count!”

“Yeah yeah, whatever, Miss Nappy Fetish!”

“OMG, I can’t believe how much of a meanie you’re being. You’re not going to apologise at all?!”

“What, apologise for you being a little crybaby? Get over yourself, baby.”

“YOU’RE THE BABY, NOT ME! Argh, I wish I could prove how wrong you are!”

Rosie disconnected after that, ending the conversation. I swiveled in my chair and chuckled. This was too perfect. My mind was whirring faster than I could keep up and type down all my thoughts into a document. Over the next hours, I frantically brainstormed ideas for how I could run the next Event, aware that I kind of had a time pressure to work out a competition for them before they came up with one themselves. After I had settled on an idea, I got to work drawing up the design documentation, including diagrams and estimated costs. I then built quick profiles on the two 19 year old girls, before carefully anonymising them and pixelating their faces. This wouldn’t be necessary after the project got the greenlight, but just in case it didn’t, it would be better if the potential targets remained anonymous for now.

Finally, I was ready. I logged onto the dark web and began to update my website.

“New Proposal: The Diaper Games

Contribute to the greatest gameshow ever produced - two girls humiliate each other, fuelled by their own rivalry and insecurity.”

Below this, the full proposal was detailed, everything from set up, to logistics, to the relevant conversation logs and profiles of the girls, all carefully anonymised.

Aika [redacted], Age 20. Virgo.
5'2, 32-25-32. Black hair.
Virgin: No. Past lovers: 4.
Occupation: Student at [redacted]
Deepest secrets:

Rosie [redacted], Age 20. Leo.
5'4, 34-25-37. Dyed dark red hair.
Virgin: No. Past lovers: Unknown.
Occupation: Student at [redacted]
Deepest secrets:
History of indulging in age play.

I hit “Publish”, and then sat back and waited.

Within minutes, the bitcoins started to roll in. Some wallet IDs were familiar to me, others were completely new. The support pledges were coming in faster than ever before. Excellent, my website was clearly still getting more popular over time.

Within hours, the initial funding goal had been reached. A couple of hours later and stretch goals 1 and 2 were already complete. I could hardly sleep that night, thinking about how big this could get. Checking my bitcoin wallets the next morning, I almost wet myself with excitement - all five stretch goals had been met. This was going to be epic.

Preparation went as smoothly as can be expected when hiring discreet criminals to set up and manage an illegal underground gameshow arena, and to kidnap two 19 year old girls. It was expensive, but hey, that’s why crowdfunding is such a beautiful thing. Rich perverts from Japan can put up the cash, and leave me to do all the risky, dirty work. That’s fine with me, since it leaves me with the bit I care about - having full creative control over my very illegal masterpieces. And boy, was this one a beauty.

Chapter 1 - Let the games begin

Aika woke up groggily, and with a slightly throbbing head. The first thing she noticed was that her mouth felt weirdly stretched, and the second thing was that she was uncomfortably sprawled on a hard floor. Opening her eyes, she was blinded by several bright coloured lights, and was unable to see anything clearly. As her eyes adjusted, they widened. All grogginess disappeared instantly as she started to panic. Staring her right in the face was a long wide clear tube that was attached to her mouth. The other end flowed up to whatever was near the ceiling - it was impossible to see properly because of all the coloured spotlights! Desperately pulling the tube away from herself, she was rather unsurprised to find that it was somehow secured to whatever gag harness she had holding her mouth open.

As she tugged on the harness around her head, looking for a strap, a low whirring noise started, and a clear liquid was pumped directly into Aika’s mouth. She was relieved to find that it was just water, but also nervous about the fact she was being forced to drink. She began gulping nevertheless, unable to do anything else as the cold water filled her mouth. She squirmed nervously, and felt some unexpected resistance between her legs. Looking down at her body, she yelped, or rather she would have yelped if she wasn’t busy drinking. She was wearing a large neon green onesie with a massively puffy crotch - it was very clear from the sight and the feel - she was wearing a thick diaper! Her thoughts immediately went back to last week’s argument with Rosie - they still weren’t on speaking terms, and there had been further accusations of childishness sent each way via passive aggressive posts on Facebook. This couldn’t be Rosie’s revenge, could it? Would her best friend really arrange for her to be kidnapped and tortured? Or if not torture, whatever this was? Surely not. Also, exactly how much water was she being forcefed?!

Aika took a better look around at her prison. She was in a large room, with three dark brick walls and then one completely pitch black wall right next to her, that almost looked like it was a giant computer monitor. She was on some kind of raised stage made of metal, with several large levers embedded into it. Lying near her on the stage was another girl… wait what?! How had she not noticed, it was Rosie! Rosie was lying next to her, identically clothed except that her onesie was a shiny pink. She had an identical tube attached to a ring gag harness on her face, and she was still out cold. Well, that ruled out Rosie from being her captor.

Aika was thankful when the water stopped pumping. She had started to find it a little difficult to keep swallowing, and she already needed to pee, as she always did first thing in the morning. She propped herself up onto her hands and knees and went to nudge her sleeping friend.

Rosie woke with a start. Aika watched her go through the same motions as she had - first being blinded by the light, then noticing the long clear tube, and trying to remove it. She turned wide eyed to Aika, looked her up and down, and then looked down at herself, before squealing as loudly as one can when they have a tube connected to a ring gag covering their throat. At that moment, her forced drinking began. She struggled violently with the tube, but in the end could also do nothing but gulp as the cold water forced its way into her body.

Aika watched as Rosie’s eyes grew wider as the flow continued. She tried to comfort Rosie, and communicate without words that it would end soon, but unfortunately all she could do was rub her shoulder and give a thumbs up sign, which was clearly taken the wrong way as Rosie shoved her away.

A minute later, Rosie’s tube stopped feeding her. She was left sitting there, groaning and rubbing her cheeks. Both their jaws were already starting to get quite tired, and there was absolutely no indication of how long they were going to be kept like this. They sat there for what felt like ages, with Rosie using her arms and hands to accuse Aika of putting them in this situation, and Aika rejecting the notion, indicating as clearly as she could that she was just as confused. This was not her idea of a pleasant morning.

A new whirring sound interrupted their interpretive mime, and they looked up to see a camera on a rod lowering itself down from the ceiling to in front of the stage, staring right at them. After it had reached its resting position, another slightly louder whirring sound took over, and both girls were pulled to their feet by their feeding tubes as they retracted by a few feet into whatever contraption they were attached to above them. A few moments passed in silence, and then the screen behind them burst into life with stunning light and sound. A musical fanfare was playing and videogame style graphics were flickering into life on the giant screen; it was divided into seven vertical sections, with each one except the rightmost displaying a different icon at the top, some words underneath, and then a clockface under that. The one on the right had an image of a statue holding up a ‘scales of justice’, with a green diaper on one scale and a pink diaper on the other. The girls only had a split second to process this before their concentration was broken again by a loud voice filling the room via some unseen speakers.

“Welcome everyone to Round 1 of the Diaper Games! These two lovely ladies have been kidnapped and brought to this secret location in order to find out once and for all who is the biggest baby!”

Wow, thought Aika, we’ve really been kidnapped. It only really hit her right then, what a crazy situation she was in.

“Aika and Rosie-” they know our names?! “-have been fighting over the past week, over which one of them is more immature. Aika, who wet her bed until she was 14, will be trying to prove she's now a grown up who can control her own bodily functions. Rosie, who has been known to dabble in adult baby play with past lovers, will be looking to show us that diapers don't turn her on. The anonymous funders of this gameshow project are watching this private livestream from around the world. So whilst the girls have an audience, it's actually quite an intimate one."

This was too bizarre for Aika to even process it properly. And the voice just kept talking.

"As you can see, our two diapered divas are standing either side of six large levers. Each of these levers controls a punishment, reflected on the wall behind them. Four of the levels control tanks full of drinks - cold coffee, apple juice, prune juice and… castor oil. By pulling a lever, the girls will be able to forcefeed their opponent a steady stream of the respective liquids. The final two levers control the ahemvibrator inside them, and the egg vibe firmly taped over their clits."

All the other information the girls were trying to process shattered into unimportant fragments as that piece of news pierced their skulls. Now that they'd been told it was there, they could indeed feel something invading their private parts and keeping them slightly open. The device couldn't be that thick or deep, since it was only a subtle feeling, but there was definitely something there. Aika couldn't feel anything above her clit, but she 100% believed it was true that there was. Perhaps surprisingly, the thing she felt most distressed about in that moment was the fact that some evil stranger had gotten very intimate with her private parts whilst she was unconscious. Still, she had very little time to properly process her feelings as the announcer was still not finished.

"While a lever is pushed to one side, the punishment will be active on one of the girls, depending on which way it's pushed. Pulling the lever towards one side will cause it to get locked in that position for a short amount of time, so your opponent can't just immediately change it back. Pulling the lever towards the middle of the stage will make Rosie take the penalty, and pulling the lever away from the middle will make Aika take it. We've got some clever sensors installed inside the diapers and gag harnesses that will let us know when the girls are using their diapers, and if any of them orgasm. The winner is the person whose diaper weighs the least at the end of the game, and the game ends when someone's diaper reaches 2kg. That sounds like a lot, but I guess we'll see!

"So what are these lovely adult babies playing for today? Well the winner of round 1 will be allowed to change immediately, and will get a proper grown-up meal at a table. The loser will be given lunch before they get to change, and will be having a meal that better reflects their mental age! Anyway, that's more than enough talking from me, let's get this game underway! Ladies, are you ready? Then GO!"

Intense background music like the sort of thing you get in an action movie filled the room, and the girls both felt some slack being reintroduced to their feeding tubes. They could now move around, although it was evident that the tubes could be used to prevent them from straying further than they were meant to. Aika's eyes met with Rosie. She tried to communicate that she didn't want to play - they should refuse to debase themselves for the entertainment of some rich sickos on the other end of the internet. But what she saw in Rosie's eyes both surprised and scared her - it was vindictiveness. Even though they were in a messed up situation like this, Rosie clearly still saw it as an opportunity to get revenge on her best friend for her transgressions last week. She took a step closer to the lever nearest her, grabbed it with both hands, and pulled it towards her own side of the stage.

BING! A bell sounded, and the screen behind the lever turned green. Aika looked at it more closely - it said "cold coffee", and this was confirmed to her a split second later as the taste hit her tongue, a slow but steady flow of the stuff making its way into her mouth, completely uninvited. The clock underneath set itself to 90 seconds, indicating that it couldn't be changed until one and a half minutes were up. Appalled by both the bitterness of her compulsory beverage and her friend's devotion to winning, Aika was given no choice but to join in. She yanked the lever nearest her in the opposite direction. The bell sounded, and then screen behind her turned green! She almost hit herself in the face with frustration - there had been way too much information to take in from the announcer's speech, and she'd already forgotten that the instructions were for her to push levers towards the middle, not just towards her side of the stage. How unnecessarily confusing!

The taste of apple juice mixed itself in with the taste of cold coffee, somehow the sweetness of the juice making the flavour worse, not better. But Aika couldn't think about that now - she had to get to the other levers! Seeing red, she charged down the stage, quickly pulling the next lever, in the correct direction this time, and then getting to the third, only to find that Rosie had run straight past her other two and headed for this one too! Aika and Rosie wrestled for control of the lever, both failing to push it in the direction they wanted because of the other girl. This went on for a few moments, with the girls staring daggers into each other's eyes, before Aika decided to gamble, and go for gold - she suddenly let go of the lever, causing Rosie to lose her balance as her weight pushed the lever. Ignoring the sound of the bell, Aika rushed over to the final two levers, pulling them both towards the middle, feeling like a champion as the two final screens turned purple, meaning she had managed to take control of three of the six levers, even with her initial mistake!

Aika looked over at Rosie, ready to gloat with her eyes, but Rosie had her own look of triumph on her face. She indicated to the green screen next to her, and Aika read the words at the same time as tasting the bad news. "Castor Oil - 60 secs". That's why Rosie had gone straight for that one - she was prioritising what was almost certainly the most brutal of all the punishments. Being combined with apple juice and coffee, it was difficult to tell exactly how much was being sent down the tube, but it felt like a LOT more than the recommended dosage. Aika knew what even a few millilitres of castor oil can do to someone, and the mere thought almost sent her trembling to her knees!

The purple punishments Rosie was currently receiving still sounded pretty brutal. Egg vibe for 120 seconds, pussy vibe for 90 seconds, and prune juice for 180 seconds. That could not be a pleasant combination. In fact, as the two girls approached each other, staring daggers, Aika thought she could see the beginnings of arousal in Rosie's cheeks. She definitely didn’t feel jealous! A loud buzzer sounded, and then the girls' tubes began pulling them back away from each other towards their starting positions, perhaps because all six levers were locked in.

It was only at this moment 30 seconds in that Aika realised she had been mindlessly and obediently swallowing liquid since the start without even thinking about it. Not that she had any other option of course, but it was extremely disconcerting to think that she had been doing it subconsciously with no resistance. Was she under the influence or something? She didn't feel drunk, but who knows how the bad guys got her into this outfit without waking her up unless she'd been sedated. And speaking of mental faculties, she now desperately needed to pee, and whilst she would normally have no problem holding it, for some reason she felt like she was on the brink of bursting against her will. How could this be?! She was not a child! Surely it was something they'd given her?

Aika and Rosie shared the same expression for the first time that morning - they both looked rather distressed. The uncertainty of the situation they were in, combined with the feeling of certainty that they weren't making it out of this game without soiling themselves was more than beginning to crack any sense of determination or competitive edge. Aika found herself wondering how Rosie was feeling. Did she need to pee just as badly? How intense were the sex toys, and did she actually feel at all turned on?

Once the girls were back in their starting positions they were essentially held in place by their head harnesses and left to gulp down their designated drinks as fast as they could manage. As the seconds ticked by Aika found that there were only two things she could think about - the disgusting taste in her mouth and the almost painful feeling of her bladder being about to burst. She was very thankful that the first lever to unlock would be the castor oil - she needed to stop that flow as soon as possible! Time seemed to be moving forward at an unbearably slow pace. 5… 4… 3… 2.. 1.. 0! As she expected, as soon as the lever was unlocked, the tubes were released from their ratchet lock and they were able to move.

Both girls sprinted for the lever, Aika reaching it first by a split second thanks to being one step closer. She was able to move the lever back to its starting upright position before Rosie got her hands on it too, leaving them standing there in a reverse tug-of-war struggle. The screen behind them was how half pink and half green, split down the middle. Aika desperately hoped that this would at least mean the flow of castor oil would stop, but the creators of this game clearly had only evil thoughts in mind when they designed it, because instead all that happened was she saw Rosie let out a muffled yelp as her mouth started filling up with castor oil as well.

So there they both stood, trapped in a fierce struggle to stop their own flows of castor oil, but in the meantime both of them on the receiving end. A few seconds later, the apple juice timer came to an end, but Aika didn't move. She wasn't sure if it was the fear of another minute of castor oil or just her feeling like for fairness' sake it was Rosie's turn, but she was not giving it up that easily. She continued to push with all her might, putting her whole body weight behind it and using every muscle she could. Unfortunately, with her focusing so much on the lever, Aika's bladder control finally failed completely.

"And so it begins!" The announcer's voice immediately appeared over the music. “Aika is the first baby to wet herself. And less than two minutes in! I don’t think anybody would have predicted that. Just how weak is her bladder?! As you can see on the scoreboard we are keeping constant track of how much her diaper weighs…”
