Chloe looked at the assembled group. Over the past three months of selection, three hundred and twenty five adults between the ages of 25 and 45 had been whittled down to the half dozen sitting nervously in front of her - three female and three male. Each had gone through extensive applications, interviews, tests and psychological profiling to reach this stage.
She cleared her throat. "We're almost ready for the final test. May I reiterate a few key points before we continue: Until you walk through those doors (pointing to the far corner of the room), you are free to leave at any time. Once you go through those doors, your old life is over. We legally become responsible for you, and take ownership of all your assets. We rename you, change your appearance, choose the food you eat, the clothes you wear and completely remould you. We will, however, explain our choices beforehand so nothing should come as a surprise. After induction, you will be allowed to make decisions for yourselves, but if they stray too close to the original 'you' we reserve the right to veto your decisions.
However, during your time in The Foundation, we will require you to make use of whatever skills you have from your previous life to benefit The Foundation, but all internet access will be closely monitored and any attempt to reconnect with your old life will be met with severe consequences.
Now for your final two tasks. At the front of the room are two marker pens - one red, one blue. Please mark one of your hands with the blue marker if you wish to be treated as a boy once you start induction, and with the red marker if you wish to be treated as a girl."
She smiled as she watched them mark their hands - interestingly two of the males marked their hands with the red marker, and one of the females marked her hand with the blue marker.
"Thank you very much. And now for the final part of your testing. To prove to us that you are really committed to becoming big babies with no bladder control, all we require you to do is to wet yourself, and remain in your wet clothes until 3pm. To assist you in your task, you will each be given a 2L bottle of water to consume. Some of you may feel very self concious about wetting - so please, whenever anyone succeeds, don't hesitate to congratulate them. While you're waiting, use the opportunity to find out more about your cohort. Take a good look at each other - as you're a fairly small cohort we've decided to keep you together throughout induction, and if you remain friendly with each other, throughout your time with The Foundation. You may also ask the staff any remaining questions you may have.
May I reiterate that all those who have successfully wet themselves by 3pm and are still in this room will be taken through those doors into their new life."
So there's your intro, it'll be interesting to see where you take it from here. You can either continue with Chloe's POV (she seems to be the matriarch around here), or shift to one of the inductees, or swap around as you see fit. You may even feel like doing the backstory - where the hell is The Foundation? What the hell is it? Why did Chloe set it up? If you take on one of the cohort, it might be worthwhile starting from, say, five minutes before this scene - putting the last signature on the legal documents before meeting the rest of the cohort.
For the sake of argument, staff live on site, there may be male staff as well as female, and sexual activity starts and stops in staff quarters (although romance may blossom between some of the students - and after induction, they may be allowed... although procreation could throw up some interesting problems for Chloe [and the couple!] if allowed). The students may show a little reluctance at what they're asked to do, but then again they're all volunteers and have handed their assets over to The Foundation. Therefore, regardless of what they're required to do, as long as they're told about it beforehand (and with more contentious aspects, why), they should be happy to go along.
I'd imagine that by the end of induction, they'll all pretty much eat, dress and act etc. as babies - except for when they're using their skills (no public contact though - unless it's in the assessment of the next cohort in 6-12 months time). They're probably the first cohort, so the staff can't place a definite time limit on induction, but it would be until they're completely settled into their new roles and couldn't imagine life any other way. Total (voluntary) loss of bladder control would be expected - what happens regarding bowels I'll leave up to you lot...
That's about the limit of my insight into this world - anything I haven't covered in either the intro or the waffle above, feel free to devise yourself. If you think you can get an entire story out of this, feel free to post one on the main story thread - "inspired by..." or a link over here will be more than enough credit. After all, this is just a random idea I concocted in about an hour. If you do manage to create anything out of this, I'll be seriously impressed!
