Sister or Mommy (Part 4) FINALE (Patreon)

 Crystal was probably letting go into her crinkly diaper for at least 30 seconds before her huge accident finally came to an end. When she finally opened her eyes, her sister... or Mommy, was smiling down at her, hand still on her crotch. Her diaper still had its cute blue, pink, and green designs on it, but a deep yellow stain had started from the center of her crotch and had quickly worked its way up to change the white padding of the diaper.

            “That’s it little one. Keep going. Finish up for Mommy.” Crystal was beyond embarrassed to be doing this in front of her sister, and even more so when the girl was now referring to herself as her Mommy; but she kept pushing. She continued to let her accident flow out of her until she couldn’t even get little drips out of her system anymore. By the point she had finally finished, Crystal’s diaper was so utterly used that it was stained yellow almost all throughout the whole thing, and the padding itself was heavily sagging in between her legs. “Good girl sweetheart.” Her new Mommy said with a small smile as she gave her sagging diaper a soft pat. “You were a very good girl for Mommy.”

            Angie stood up with her smile still on her face. “Now baby, Mommy is going to go get you a snack. You wait here and play with your toys, okay?” She started to walk away towards the kitchen. Crystal took a deep breath to speak,

            “B-but Angie w-wai...” Her words got cut off by the extremely stern look that her younger sister sent her way as she looked over her shoulder. “I m- mean... uh... M-Mommy...” Crystal stuttered out.

            “Yes Dear?” Angie said, her stern look glowing bright and pleased.

            “C-can I uh... can I change first?”

            Angie looked thoughtful as she came back over and knelt down as she pressed her hand on Crystal’s diaper one more time. “Hmmm... babygirl, I know you’re sagging a little bit, but trust me, this diapie is far away from leaking.” She kissed her again on the forehead. “You can stay in that one at least until we’re done with snack time.”

            Crystal had a small surprised look on her face as her new Mommy stood up again and left for the kitchen. She realized that she was now effectively under her sister’s control even when it came to using the bathroom when she wanted or changing herself after she had clearly failed to do so.

            Despite her concerns on that though, she did her best to ignore it and went to do what her sister said. Her diaper squished beneath her as she rolled onto her tummy and grabbed some of her stuffed animals that she had left out. She loved her stuffed animals. She had had a few when she’d been living at home, but ever since she’d had the freedom to buy anything she’d wanted without her parents seeing all the packages, she’d bought an obscene amount of stuffed animals. She’d be lying though if she said she regretted any of the purchases of her fluffy new friends.

            Angie was humming to herself as she whipped up her new babygirl a snack in the kitchen. She could still watch her through a small window that separated the two rooms. Watching her she could tell that even in her soggy diaper, the girl was wholeheartedly enjoying herself. As soon as she wasn’t being watched by someone else she had completely relaxed again and had started acting like the three year old she was dressed as. She was having playing some game with her stuffed animals and had given them different voices that Angie couldn’t overhear. Her babygirl really was adorable. It was simply a matter of time before she became a little more comfortable having her “Mommy” around while she played. Angie was determined that that would happen soon enough.

            After a few minutes as she played, Crystal had almost forgotten that there was another person in the house. She had fallen deeply back into her Little mindset. She giggled a little as she began to crawl over to her other stuffies so that they could join in her game... when she was stopped by a sudden gurgle in her tummy. She heard her tummy groan a little as she froze in her tracks.

            Simultaneously, Angie was carrying her tray of snacks into the room when she saw her Babygirl’s wide-eyed look as she froze in her spot. Angie was about to say something to at least make sure Crystal was okay, but she didn’t need to. Before she even could, she heard a tiny fart pop out of her sister’s butt. As she watched the girl started to groan softly, and spread her hands out as she leaned forward more. As Angie watched, Crystal’s saggy padded butt stuck more and more up in the air and the girl let out a grunt as she began to push.

            It didn’t take much effort before her diaper heavily pushed outwards and sagged even more in the back as a large brown stain began coating the bottom layer of her diaper. Crystal grit her teeth as she grunted again and again and pushed her butt out even further into the air. The warm mushy squishy mess filled every crevice of her diaper as her younger sister watched the entire thing.

            Angie was truthfully a little shocked as she watched the mess fill up her older sisters diaper, but after a moment she laughed a little. ‘I guess I should have expected that.’ She thought to herself. ‘I am a Mommy now. Time to clean up my little baby’s mess. Or... maybe I’ll still wait until after snack time...’
