Switching Glasses

Jeremy had just finished having his breakfast and was heading back upstairs to his room to grab the glasses but upon entering his room he saw his little sister Emma sat on the floor with the brief case open, "Jeremy what do these do?", she said as she put on the red pair and was holding the blue pair in her hands pressing the button on the side trying to figure out what they did.

"Oh Emma, those are delicate so please don't mess around with them", Jeremy spoke trying to get her to put them down. "aw can't we play secret agent with them, come on Jeremy" she said innocently standing up and approaching Jeremy who had gotten down on one knee to try and get her to stop playing with the glasses, "Maybe later..." he was cut short as she placed the glasses on his head and pressed the button on hers.

"This is secret agent Emma, over..." Emma spoke but then stopped herself as she noticed something different with her voice, she then looked in front of her only to be shocked by what she saw, "Wh.. What is going on, why do you look like me", Emma said rather shocked but also curious. Jeremy was coming back to his senses after the his vision was just flipped, he could hear his own voice talking to him, "Emma calm down, I am Jeremy and those glasses switched our bodies when you pressed the button on the side, I think because you had already pressed the button on mine it was already active when you pressed the one on yours so the switch happened". Emma looked down and then at her own body before her eyes wondered over to the mirror in the corner, "Oh my god, I really am you, Jeremy. Wait, that means I am a yucky boy." she said as she was still in a bit of disbelief at the fact she was now in her older brothers body.

"OK Emma this is really important, we cant swap back for 3 hours, so we are stuck like this for a little while. I didn't create the rules but the people who gave me the device told me it was limited to one swap every 3 hours per person". Emma was a little upset at this news at first but her expression changed quite quickly as she realized she didn't have to go shopping today which was something she didn't want to do, "Mum wanted to take me shopping today for kindergarten supplies and clothes, your going to have to go in my place", Jeremy sighed as she was right he would have to go in her place which would mean he would be in her body a lot longer than 3 hours and would instead be stuck in her body for almost the entire day, "OK Emma you can play video games on my PC if you like just don't do anything I wouldn't do please". Emma's borrowed face lit up at the thought of playing video games all day.

Jeremy put the glasses back in their case but this time he put a padlock he had on his desk on the case so nobody could end up accidentally causing another switch before he gets home. "Bye Jeremy" he said as he left his room and went over to his sisters room. "Goodbye Emma, have fun" she said as he shut the door. Jeremy retreated to Emma's room, in all the confusion and panic he hadn't had a chance to really take in the fact he was in a body a fraction of his age, he looked in the mirror on Emma's wardrobe, he was wearing her favorite pink night dress, it was really girly and had lace frills around the hem, underneath the dress he found a surprise, he was wearing a diaper, or pull-up as his sister liked to call them as it sounded more mature, he had completely forgotten that his sister was still potty training or well was he now the one potty training since he was the one in her body. He lifted up the nightie so he could inspect the diaper in the mirror a little bit more and just as he suspected the princess pattern on the front was faded indicating that it had been used. He let the nightie drop back down and decided to lay down on her bed for a little bit since he had nothing else to do and he didn't really fancy playing with dolls.

As he was laying down he was thinking about how he managed to get into this situation, it still felt so unreal to him that this type of technology existed and that it had been given to him to test, he then realized that even though he didn't plan this swap he was still planning on swapping with someone today and that this swap would probably provide Lucy and Dr Cooper with a lot of valuable research data, after all its not every day that someone can experience going back to being a four year old. He was so lost in his thoughts that he hadn't even realized that his new body was subconsciously wetting the diaper he was wearing until he felt the warmth spreading bellow. "Oh my god, I am wetting myself, well I guess that answers my question on whether it was the body or the mind that would win in a battle over potty training", he sat up and felt the diaper sag as he did a bit of a waddle over to the door to try and figure out what to do.

As he approached the door someone else was approaching the other side... [Who was it?]
