"Wow! This place is lovely!" Lisa said as she walks through the living room. "It's so clean and quiet!"
"And we can see the ocean through this windows! So cool!" Billy said as he watched outside. "There's a river over there!"
"You want to hang out and see what's out there, don't you?" Lisa told him. "Just let me change my clothes and we can go."
"Ok, I'm taking my swim trunks too." Billy replied but his mother had already left the living room. He quickly changed his clothes and went to the kitchen to look for a snack.
"What's this?" He said as he watched the note that was left for his mother.
"I'm ready!" Lisa said as she made a quick a pose for her son.
"Is this real, mom?" Billy asked her. "We can change our age in this place?"
"That's what it says. I'm not sure how it works." Lisa said. "I was hoping for getting a little bit younger during this vacation. You know, remember good times."
"I don't know. It's kind of awkward to think about you as a girl of my age or even younger." Billy replied.
"I'm not going to be that young." She told him. "I was thinking of my twenties. I didn't enjoy them that much because of..." She stopped talking.
"Because of me. You needed to take care of me during those years." Billy gave her a brief smile. "I understand."
"Don't feel bad about it. I don't regret my choices. I love you and I love being your mother. Also, you were soo cute at that age!" She said. "It's not that you're ugly now, you're quite handsome but was the cutest toddler I'd seen!!"
"Aw, mom! Stop it!" Billy blushed. "You're embarrassing me."
"I got an idea. Change our ages right now, both of us. 12 years younger." She told her son. "Just for today. Let me remember those days when you were my little boy!"
"I'm not sure." Billy said. "I'm going to be a baby again. And this note says I'll be incontinent."
"I can take care of you like I did back then." Lisa smiled at her son.
"But you'll see me, I mean... naked."
"I saw you naked all the time when you were a baby. You had a cute little dick and those cute squeezable buttocks!"
"Mom!!" Billy shouted ashamed.
"Oh, please. Just for today!" She said. "Then, I'll let you become older and do adult stuff like all the kids want."
"I don't want that." Billy sighed. "Alright. I'll do it."
"Oh, thanks! Thank you so much honey!"
"Aaand... How do we do it?" Billy asked.
"The water." She said. "There are three types of water in this place. Regular water, youth water and age water. The sink, shower, pools, etc. have these three types of water running through them. However you can't measure how much you're going to change. That's why they sell these water bottles." She took two small bottles from the fridge and gave one to her son. "Drink it and you'll become 12 years younger for 24 hours."
"You already have it. Were you planning to turn me into a baby since before?" Billy questioned her.
"No." She said as she drank her bottle. "I was expecting to drink one each day we're here." She immediately started to get younger. Her body getting more defined, her hair growing thicker and healthier. All the signs of age on her skin vanishing until she looked radiant.
"Wow, mom! You look beautiful!"
"Thanks. Now, it's your turn. I want to see my baby again!" She giggled.
"Ok, here goes nothing!" He drank his bottle so fast that he regressed fast too. He was as tall as his mother, but when his height shot down he only reached her knees. The world seemed suddenly huge to him. He looked at his hands, they were so tiny and weak that he knew he needed to be taken care of. He tried to walk but his legs were also too weak that he fell and instinctively started to cry.
"Aw, don't cry little man! Mommy is here!" She grabbed him between her arms and he stopped crying. "Now, who wants to go to the beach?"
"Mommy, dwon't tweat me like baby! I'm bwig boy!" Billy tried to say but realized that regressing also affected his mind, his way of talking and...
"Oh oh! It seems that my baby can't wear big boys clothes anymore." Lisa said as she saw her son peeing on his swim trunks. "Let's put a diaper on that tushy!!"
"Mom! Nooo!!" Billy tried to protest but his mother was already taking off his trunks.
"Aww!! Your little pee pee is wet!!" Lisa said.
"Nooo!!!" Billy yelled of such embarrassment.
