It's fluffy and it shows more than you'd think, An A1386G Sidestory.
AN: This is off to the side of A1386G, neither is required to understand the other, but added context is always fun. It's also more a 1.5 than anything else because not much happens in this chapter, but character limits.
Rebecca was sitting on the bed in the guest room coloring by herself when she heard the door open. She wasn't really fond of all of the things her maid had done to her in the last day or two. But coloring was nice. As was not having to get up to pee while coloring. And she even had a coloring book by one of her favorite comic illustrators!
She heard the door squeak as it opened. "Well, Becky I have good news." A familiar voice said as Rebecca turned to look at the door.
It took her a moment to place who the woman was before she realized it was Constance, her boyfriend's elder sister, just wearing her hair in a side braid and with different body language than usual. Also, in a frilly apron she had clearly retrieved from a costume closet.
"Oh?" Rebecca said, trying to figure out what was going on.
"Since your mommy had to run out and get some stuff for tomorrow before she hit the gym, she asked me to watch your perverted ass for a few hours." Constance said.
"I'm eighteen years old." Rebecca said, as the older girl sat down on the bed next to her. "I don't need a babysitter."
"You're wearing a diaper under your dress and coloring a Princess Horsey Horse coloring book." Constance replied. "Honesty really thinks you need a babysitter, and frankly you don't look eighteen right now. You look four."
"But why you, and not Marie?"
"Nobody trusts Marie to keep you away from the baby, and I can change a diaper."
"Wait, what?"
"I have a disabled sister and a baby in the house. Did you honestly think I didn't know how to change a diaper?" Constance said as she looked the younger girl dead in the eyes.
"Grace wears diapers?"
"Yes, Grace has to wear them occasionally." Constance said. "If you ever see her in a wheelchair, she's probably wearing a diaper."
"So she's..."
"Kind of like you, but not a pervert." Constance replied. "She is lazy though, so she does take advantage of it."
"But why do I have to be kept away from Katerina?" Rebecca asked as she pushed herself up.
"We're afraid you might confuse her." Constance replied.
"She's two months old."
"And Janice is very concerned about her daughter." Constance said as she patted the younger girl's head.
"Okay." Rebecca said.
"So while you're here in the guest bedroom, you can be as little as you, your mommy or I want." Constance said, as she removed her hand. "But from now on you have to actually be an adult in the rest of the condo, aside from my brother's suite if he allows it. You can be padded, but no more cheddar bunnies and sangria or punch in sippy cups in the main room."
"Oh come on, that's the only thing worth going through all this."
