Bobby was about to make his wish for Ashley to be older when he felt a hand on his shoulder. "Not so fast you two," said Jennifer, having walked back into the room. She glanced over Bobby's shoulder to see Mandy and Mike on the couch. "So they got started without me," she said with a little annoyance before returning her attention to Bobby and Ashley, "You two aren't going to have fun just yet. I've got an idea so we won't have to worry about watching over a certain little baby."

Jennifer had placed Jimmy on his own bed, which was ridiculously too big for his little baby body. Fortunately, Jimmy had dozed off by the time that Bobby, Ashley, and Jennifer had returned. Jennifer looked down at her brother with a smile. Such irony that only a few minutes ago, he was her older brother by 4 years and now she was 20 times his age. Jimmy had been pretty pushy and did not react well someone became more superior than him. It probably would have been simpler to just leave him as a 1 year old baby while the 'grown ups' had their fun. But then they'd have to waste a lot of time taking care of him. But if this worked as Jennifer hoped, he'd be a lot more amiable.
"Ready, Bobby?" asked Jennifer. Bobby nodded and activated the ring's power. It didn't have any noticeable effects on Jimmy, but then Bobby had only wished that his mind be aged back to his 9 year old self. Jennifer waited a while until she was certain enough time had passed. Then she reached down and tickled Jimmy's belly. Jimmy soon woke up and looked around in confusion. When his gaze fell upon them, an angry look appeared in his eyes and he shouted at them, though his words only came out as cross babyish gibberish. "Oh, did we not enjoy our nap?" teased Jennifer. Jimmy glared and tried to sit up, but his tiny muscles were not very coordinated.
"Well, little brother, you can keep acting like a baby or you could listen to a proposition that could mean you won't have to stay that way," said Jennifer. Jimmy stopped and looked at her with interest. "I'm offering you a chance to get out of babyhood and really enjoy the perks of having your age changed. You just need to do one simple thing," said Jennifer before nodding to Bobby. Bobby nodded back and activated the ring's power again.
Ashley grinned as her body began to grow again. Her 10 year old body grew taller as her clothes became less ill-fitting. But Ashley wasn't waiting for her body to grow into her clothes. As soon as her nipples started to puff out, she pulled off her shirt. Puberty course through her body again as she stood their topless. Her nipples grew until they started rising up atop a pair of mounds. She grinned as her breasts grew bigger and rounder. The rest of her body matured, waist caving in, hips flaring out, ass rounding out. Quite soon, she was a young woman of 20 again. She ran her hands over her large breasts and moaned with pleasure.
As Jennifer expected, Jimmy's attention were locked on Ashley's breasts. Good, this will make the next part easier. "If you want to be a big boy again, all you have to do is suck on her breast," said Jennifer. Jimmy snapped his gaze away from Ashley's bosom and gave Jennifer a look of shock and outrage. "Don't think about saying 'no' so quickly, not that you can say anything right now. We could just de-age your mind and make you think like a baby instead." An insidious smile appeared on Jennifer's lips. "Or, if you're going to be totally unreasonable, we could make you so young that there won't be any of you left. I'm not sure what will happen, but I bet you'll end up inside my belly." Jimmy's expression turned to one of horror. "Yes, I'll become your mother instead of your sister, not a pleasant thought for you, is it? So, Jimmy, are you going to be a good little boy now?"
