Grace is behind it all

Her plan was working. Penny would be in diapers in no time, and then, she would finally have **** on her sister, always making fun of her all those years before.

You see, Penny was not the innocent big sister she might seem to be. In fact, Penny can be quite the bitch especially to her younger sister. Penny might not remember it and may even deny it, but when they were younger, Penny would always pick on Grace. She would bully her, tease her, and humiliate her. Secretly, Penny had always been envious of her younger sister’s body as she grew boobs faster and bigger and in Penny’s eyes was way more attractive than she was.

Penny would project her feelings onto Grace by picking on her. Grace sometimes had irregular periods due to her early growth spurt and puberty, so she would sometimes wear Maxi pads to stop the heavy flows. One day, Penny decided it would be funny to pants Grace in the middle of the hallway in front of her girl and guy friends to reveal to them the large puffy pad. It was only one time in high school, but Grace never was able to let it down. And Grace never forgot about it. She finally decided after years of planning, that she would get **** on Penny.

So yes, she was the reason Penny was suddenly having bladder problems. She read online that after a certain amount of days of a person wetting themselves consecutively or at least frequently, the body would start to regress to its natural state unless something was to be done to retrain it like potty training. Retraining the body to not wet itself was even harder than training it in the first place.

So Grace got the brilliant idea to start her plan just a few weeks before Penny’s 25th birthday so that for her birthday she would be regressed to having the bladder of a newborn baby and would have to wear diapers not just at night time, but 24/7. She started with the classic warm water in a bowl trick. She wasn't sure if it would work, but it did as Penny dosed fast asleep, Grace did her magic.

She was disappointed that Penny woke up before her and was able to change her sheets and clean up before she was able to tell their mom about it. So this time, she made sure she would be able to catch Penny in the act as she not only used the warm water trick again but also put a sleeping tablet in her water right before she went to bed. Penny was too busy peeing to realize that the water she drank after brushing her teeth was dosed with sleep medicine.

This night Grace wanted to see if Penny would wet the bed on her own. She dosed Penny’s water again with sleeping tablets ensuring that Penny would fall fast asleep and this time she also set up a hidden camera in Penny’s room. It was motion sensitive so as soon as Penny moved to get up, Grace would be alerted and the whole thing would also be recorded.

After what felt like a long day of wearing the Goodnites, Penny made sure to go to the bathroom, emptying out completely before brushing her teeth and drinking the water that was unknowingly dosed with sleeping tablets. Penny yawned as she laid down on the bed, not even able to pull the blankets over her body before she was fast asleep.
