After Mark had calmed enough again to speak he continued. “Now, as you have the body of a twelve year old child again there will be two things that change. First, you can´t life alone anymore. Therefore you will life with your new family, which is mine, as an adoptive little brother. Second, you will need to go back to school again, Aidan. But as you act as a toddler, you can´t go to a higher class as a simple first grade in elementary school. So now you will go just there as a first grader. Every teacher will be endless patient with you and never rant about you, knowing you are far behind others in your new grade. You will have a strong difficulty in learning anything, and what you know as a 28 year old in mind will be blocked by heavy fog, which will also cover up everything you learn over time again. You can fight the fog and find answers, but even then it won´t help the toddler in any way. You won´t be able to learn reading, and writing will always end in an unreadable scrawl.
Your classmates will tease you sometimes, but never harm you. But this teasing will be enough for you to let go of your bowels with a maximum of once per hour. Beside that with a maximum of once per hour too if someone compliments you or pets your head you will loose control of your bladder. At the same time both your bladder and your bowels will fill up rather fast so that there is enough for you to lose after that time. And nobody wonders why your diaper cleans from alone.
As you can only talk without the pacifier everyone around you knows this, they will remove it when they ask you something. But they also know that without the pacifier inside your mouth you will start bawling. You are allowed to stay in your classroom the whole day as everyone knows you can´t walk alone, and someone had to both bring you to and get you from the school each day. Your teacher will gave you your bottle in the break, which you will drink empty before it is removed. The bottle will have a random taste to you, some good and some bad, but the toddler will like them all, and others will see and taste simple milk. Finally you will never grow older in any way, so you will return to first grade every time after the holidays.”
Aidan looked horrified at Mark. “He can´t be serious about that.” he thought. But the effects were already starting. Aidan felt himself getting dumber as his knowledge more and more vanished behind a heavy fog. He could move into the fog and uncover it again, but never take it with him outside as it was covered again. His memories weren´t affected by the fog, so he knows everything that has happened to him. But knowledgeable he was now as dense as a rock. The only other thing he noticed was a bit of pressure building in both his bladder and his bowels.
Mark grinned at Aidan, seeing the light in his eyes dim a bit. He would have to test the changes again. After Aidan had cummed again, as the new change had reset the timer, Mark took the pacifier out. “Aidan, what is the capital of our country?” Aidan looked at him with a mostly helpless look, but a bit of anger was under it. “Me do no.” was his reply. Mark grinned at him, as slowly his eyes started to leak tears. “It´s okay, little Aidan. That´s why you go to school to learn.” He gave Aidan the pacifier back before petting him reassuring. That resulted, like Mark had wanted, in Aidan filling his diaper with the contents of his bladder. His face brightened as the toddler got a new treat from the pacifier.
Mark decided to not try to tease Aidan for know, so he only said: “Well then, let me pack up the laptop and then we will go home. Okay, little guy?” But that did only lead to Aidan crying. Unsure what was wrong now, Mark took the pacifier out again, only for Aidan to bawl out: “Me home, no go.” Mark gave him the pacifier back before replying: “Ah, but you can´t stay here all alone, little Aidan. You are now my adopted little brother, so you are at home with me and not here anymore.” He could see Aidan slowly stopped crying around his pacifier, but deep in the eyes he could see him looking horrified again. Mark realized that the comment was accepted as true for the toddler, but Aidan still knows he is at home here, and smiled at him. He loved to torture Aidan, even if he was mostly unable to express it.
So, a couple of minutes later the laptop was packed and only then Mark noticed that he would need to carry little Aidan home now, or he would need to change something into a big stroller.
