"Now!!" he thought as he snagged the balloon. His sister had left it in his reach Jim blew into it and thought "Control my sisters age and mind." He let it go and it flew around the room landing with a plop. At the same time his sister started to get younger. She passed 24 her sender figure started to change the curves disappearing her clothing getting saggy. "Why you little brat." she yelled. Her shrinking did not stop passing the age of 10 her breast sucked into her chest as baby fat started to appear. She found it hard to stay standing up collapsing into her mother clothing she had been warring. Jim landed safely on the bed and waddled to the balloon. His sister passed age 3 and rolled on to her back flailing her fat little arms. "Wes wommy gets hwome me goes to twell her everyding." Judy tried to talk but it started to sound like baby babble. Jim looked at her grinning "you can’t tell what you can't remember, have fun in diaper land baby sister." Judy, who had to be no more that 1 now look at him in tears. "Pwese bwig bwoder i no wat to we waby.... bassbggoo.." Judy's transformation was complete she laid there in the pile of clothing crying. Jim grabbed the balloon and blew into it saying "control the age of my wee wee and the age of me." He blew FOOFFF, he return to the age he was before this all happened and his penis reappeared. "Now who's the baby?" Jim grabbed the crying Judy and pinned the thick diaper he was just warring on her and pulled the plastic pants over them. He then when into his room and got dressed. Jim returned to the room with an old play pen and a bunch of baby things: cloth diapers, toys, clothing, and a pacifier. Jim stuffed the pacifier into her mouth and dressed her in the same outfit he was just in. and set her in the play pen with toys and a bottle of milk. "Now you be good for you big brother Jimmy." he laughed patting her on her well diapered bum. "I think a few weeks of this will teach you to help you brother when he needs it. Jim smelled something coming from his baby sister. Jim picked her up and laid her on the bed and unpinned her messy diaper wiping her down then placing a ticker diaper under her and powdered her little diapered area. Jim then pulled the diaper up and pinned it in place. "There all clean, he said. With that he placed her back in the pen.
