Mikey decided he would make Jon into a proper girl, it would be more fun to push her around when she becomes younger, especially if he gave him his own mind back when he, no she, he chuckled to himself, is too little to do anything about it. "I wish Jon was now fully female and his name is now Janey". Mikey glanced over at his new sister who had gone to the kitchen to pour herself a glass of juice, she didn't look much different than before, her features looked a little softer & girly, her hair also a bit longer and in a more feminine style, small A-cup breasts pushed out her now pink blouse, bra straps just visible through it over her narrow shoulders and the tight fitting jeans left no doubt on what was missing down there. He also noticed as Janey stood there she moved and gestured just like a girl.
But although Mikey was pleased with this new development, he wanted a little sister, not a big one, having a big sister would be worse than how Jon was before. He decided to test out how much like a girl Jon now acted and to annoy him some more and provoke him into making himself an even younger girl.
"Hey sis, I've taken out the rubbish", he said sneaking up behind his sister and pinged one of her bra straps like an elastic band, then ran away to Jons, now Janeys room. Janeys little breasts jiggled and she felt a sharp pain when it hit her back. She ran upstairs intending to get even with her little brother. He was standing in her room amazed that the wish had even altered that, it was now decorated like a teenage girls room with boy band posters and a few stuffed animals and painted a pale purple color. She was very annoyed at finding her nasty little brother in there and let out a torrent of abuse, he just smiled as both his new sister and the room altered. The bra straps no longer showed through her blouse as her breasts melted away to nothing until she was as flat chested as a boy, her hair altering style into two braids and her face getting even more youthful and innocent, she also started to shrink until she was over a foot smaller than her now big brother, her jeans turning pink and then fusing with her blouse turning into a little girls dress, showing off her little girl legs, with frilly little ankle socks and black maryjanes. The boy band posters on the wall disappearing and more toys, dolls and stuff apearing, pictures of faries and ballerina's adorning the now little girls room.
Now she was so little, she never had any bra straps for her brother to pull and had forgotten why she came up to her room and why her big brother was there, she looked at him puzzled. He quickly thought, "Janey mom told me to start saving for a birthday present for you, how old will you be then", "Th'seven silly" she said with a slight lisp, picking up one of her dolls and combing its hair. "Anyway didn't mommy say you should be mowing the lawn", she squeaked out as she dropped another year to age 5. Mikey giggled, any more of this and she'll be in diapers.
.......Meanwhile Karyn had been out of town to visit a sick relative and had been out of range of the stones powers and planned to visit Jon the minute she got back, so they could have some fun with it. After an hour or so drive back with her mother she arrived at Jon's house to find a cute little girl playing with dolls on his front lawn.
