-NOT EDITED-

Ann finished up the dishes as fast as she could. Checking her phone, she saw that her mom had texted her,

9:32am | Mom: 'got a text from your grandmother saying she needed some help with earns, so I'll be back in a few hours. Remember, use your diaper, I need to see how much it can hold, I'll change you when I get back.

-love you💕'

9:46am | Ann: 'okay, sounds good. Please try get back as fast as you can, I kinda have to pee and I don't want to sit in a wet diaper.'

9:48am | mom: 'aww does someone have to go pee in her diapee.'

Ann turned completely red at her moms babyish teasing. She knew her mom was just kidding around like always, but Ann was embarrassment after what happened with Eric was already to much, she was already feeling like a baby after that and her mom wasn't helping.

9:49am | Ann: 'mom! I'm not a baby! Please just hurry.'

9:51:am | mom: 'your soon to be wet nappy says otherwise. Ooo maybe the little baby is cranky because she needs to go poo poo. Don't worry Mommy will be home as soon as possible to change baby Ann's stinky diaper."

Ann cringed as she read her mothers texts. She could practically see her mother smirking as she teased her.

'Poo poo? Nappy? Mommy? Little baby? Wtf! Ew ew she can't actually think I'd ever poop a diaper! And have to sit in it! Ew!' She thought, and was To embarrassed to even reply to her mom. Not that she would've had time to anyway, as eric made his was down the stairs with something in hand.

"Okay diaper baby, you listen to everything I say and don't tell anyone about this and I wont show anyone that video, now, let's get started." Eric says, making his way to the fridge, pulling out an old baby bottle from when they were little and filling it up with milk.

"I think baby needs her bottle", eric teases, smirking.

"Eric you can't be serious!"

"Bad baby-" eric spins around and pulls Ann's pants down, and smacks her padded bum. "-okay baby, now I want you to follow me to the living room."

Ann just nods, and starts following him, but is stopped by Eric

"Silly girl, babies crawl".

Ann reluctantly got down on her hands and knees, and waiting for Eric, diaper exposed and face red. But he didn't move.

"Oh no, baby Ann is going to crawl all the way to the living room by herself like a big brave baby while I watch you struggle from back here in that big baby diaper. Go on, crawl."

Ann let out a whimper of embarrassment and started to crawl. The diaper was thick between her legs, forcing them apart and making her crawl like a real baby. Of course, to add to her embarrassment, Eric teased her with saying things like 'aww look at baby's diapered butt swishing' and 'what a big diaper girl". Ann had never felt more relieved when she made it to the living room. Eric came up behind her, picked her up and pulled the back of her diaper up.

Ann yelped, squirming as Eric laughed at her facial expressions. He grabbed the front of her diaper as well and pulled up, And moved them to the couch and grabbed the bottle. He sat Ann on his lap like a baby a put the nipple of the bottle in her mouth, tell her that if she didn't drink he would punish her. Ann didn't know what could possibly be a worse punishment then this, but she opened her mouth and let her older foster brother bottle feed her like a 1 year old.

"That's it, good girl, drink it all up." Eric said, patting her diapered ass and smirking as he watched Ann become completely a helpless baby. Ann finishes the bottle and Eric tells her 'good job'.

"Woo this diaper is huge-" he comments, squishing it and smacking the padded underwear. "-it's gonna be so much bigger once baby goes potty in it. Does baby Ann need to go wee wee in her nappy? Or better, poopy.-" Eric smirks at Ann's wide eyes at his teasing. She was so easy to embarrass and Eric loved it. Ann was always a brat and she deserved to be put in her place. She never had let him be apart of the family. Never let him be close to his foster dad or mom. He'd known her for 3 years and she'd been nothing but a bratty baby.

"Ooo baby does need to go potty," he said, and started to lightly push on her stomach. Ann wiggled at the pressure, the bottle of milk felt like it had gone straight through her and not to mention she already needed to pee from that orange juice earlier. Blushing and whimper underneath the urge to go, Eric sat her so that she was facing him, applying more pressure.

"Tell your big brother what you need to do in your nappy Ann, does baby need to go wee wee or boom boom?" Eric laughed at his foster sisters babyish state and squirming, and made her look him in the eyes while pushing in her bladder even harder.

"Well, I'm waiting? and remember, baby's use baby word?"

Ann now completely desperate. She knew there was no way Eric would let her go to the bathroom so she didn't even bother trying. hands trying to hold her crotch and stop from pissing, Ann started to cry as she was forced to look eric in the eyes and tell him what she need to do in her diaper.

"I needs to go pee pees and poopies in my diapee".

Eric smirked and put his other hand on the front of her diaper, moving hers from trying to hold it in and pushed even harder on her stomach with the other. Ann couldn't take it, she was squirming and wiggling and Eric was laughing at her embarrassment. His hand on her bladder was too much and she realized this was it, she was about to piss her diaper like a baby in front of her foster brother. She hoped maybe, just maybe she could pee without shitting herself as well. And then it happened. Ann froze as she heard the hissing and Eric watched her completely mortification. Eyes wide, she couldn't even cry, she was just to shocked. The piss made the diaper ever bigger and warm, and to make it even worse, she was brought back to reality by her brother laughing and squishing the now huge bulge in her diaper.

"Aww did baby go pee pee in her big baby diaper?" Eric mocked.

And then, so Ann's horror and Eric's amusement, Ann started to shit herself. Her hands flew to her butt, trying to keep it in,but this just made Eric aware of her situation as he realized what ann was about to do. He tried to hold in his laughter and just smirked at his sisters terror as he moved her hands away from her ass and turned her around so that her ass was facing hun. Ann didn't know what was wrong with her but she couldn't hold it in, she felt Eric pull back her diaper and realized he planned on watching her shit her diaper, and was powerless to do anything about it. She didn't even need to push, her shit came out one after the other. She really was a big baby not, she was literally shitting her diaper and couldn't stop. Her diaper was wet as mushy and tears were streaming down her face as Eric laughed at her eyes humiliating situation and the mess he was watching being made in her diaper. He turned her around to face him and watch her facial expressions of disgust and embarrassment. He laughed to himself, who knew laxatives could make someone into such a big baby
