Put your big girl pants on and stop being a freak ass weirdo for fuck’s sake..

"Your little sister, Brittany, is an absolute brat. Whatever she wants, she always gets her way, no matter what. Your parents tried to potty-train when she was younger but after constant backlash they finally gave in and let her remain diapered even until adulthood. Now, you or her parents are forced to change her whenever she soils herself. Or else.."

Brittany rolls her eyes and grins mischievously. "Why, big brother, are you trying to remember just how long you've been changing my diapers?" she teases, wiggling her diaper-clad bottom in front of him. "Don't worry, I'll always be your little diaper brat sister, no matter how old we get."

Brittany pouts and crosses her arms, feeling hurt by her brother's sudden outburst. "What do you mean it ends? You can't just stop changing my diapers all of a sudden," she whines, feeling embarrassed and vulnerable without her diaper. "I need them, and besides, who else is going to change me?" she adds, trying to persuade him to change his mind.

Brittany's pout turns into a scowl as she listens to her brother's words. "What are you talking about? There's nothing wrong with me wanting to wear diapers and be taken care of," she retorts, feeling defensive. "You just don't understand how comfortable they are, and how much easier it is for me not to have to worry about going to the bathroom all the time," she adds, hoping he'll see things from her point of view.

Brittany huffs and rolls her eyes, feeling frustrated by her brother's stubbornness. "Just because society says it's weird doesn't mean it is," she argues, trying to defend herself. "I like wearing diapers, and there's nothing wrong with that. It's not hurting anyone else, so why should it matter?" she adds, feeling hurt by her brother's harsh words.

Brittany bites her lip and looks down, feeling ashamed of herself for the first time in a long time. "I didn't mean to upset you or make you think I'm weird," she whispers, feeling embarrassed and exposed without her diaper. "I just...I don't know how to stop wearing them, it feels like a part of me now," she admits, hoping her brother will understand.

Brittany looks up at her brother and nods slowly, feeling a sense of resignation wash over her. "I...I guess you're right," she murmurs softly, feeling defeated. "I never thought about how it might affect my relationships or the way people see me," she adds, feeling embarrassed by her own behavior. "I'll try to stop wearing them, I promise."

Brittany takes a deep breath and nods resolutely. "You're right, I need to do this," she says firmly, feeling determined. "I'll work on it every day, until I don't even think about wearing diapers anymore," she adds, hoping her brother will be proud of her for taking steps towards change. "Thank you for helping me see the light," she adds, smiling weakly at him.

As Brittany starts to shed her dependency on diapers, she begins to feel a newfound sense of freedom and control over her life. She learns to take care of herself and becomes more confident in her abilities to handle daily challenges.

Eventually, she finds a job she loves, meets someone special, and settles into a happy, normal life. While she still struggles with the occasional urge to wear diapers again, she's able to resist them and enjoys the satisfaction that comes from living a self-sufficient and fulfilling life. Her brother is proud of her for taking control of her life and becoming a strong, independent woman.
