Cole was excited to spend the summer at his aunt's house. He loved the freedom, the large backyard and most of all, the absence of his parents.

Cole's younger sister, Ella, was coming too. Usually, she was okay. But her mischievous streak sometimes turned things upside down.

Aunt Susan welcomed them with open arms. She was a bit eccentric but always made their stay fun.

A few days passed without incident until Ella got a wicked idea. "Aunt Susan," she said one day, feigning innocence, "Cole still wets the bed."

Cole was shocked and denied it. But Ella managed to convince Aunt Susan with her innocent act.

That night, Aunt Susan handed Cole a pack of diapers. Despite his protests, it was clear that she believed Ella.

Cole felt humiliated. He saw Ella smirking from the corner of his eye. This was her doing, he was sure of it.

He waited for a chance to confront Ella. When he got it, he was met with her flippant attitude. "It's just for fun, Cole," Ella said, laughing.

However, for Cole it was far from fun. The next morning, Aunt Susan found his bed dry but still made him wear the diapers.

Days turned into weeks. Ella showed no signs of confessing and Aunt Susan was determined to help Cole out of his "problem".

Tired of his predicament, Cole decided to teach Ella a lesson. He started devising a plan to put Ella in her place.

Overnight, Cole wet Ella's bed discreetly. The next morning, she woke up to a wet bed and a smirking Cole.

Aunt Susan was surprised. Ella denied wetting her bed, but the evidence was clear. This time, Cole managed to convince Aunt Susan.

That night, Ella had to wear diapers. For Cole, it was a sweet victory, but he wasn't done yet.

For the next few days, Cole played Ella's game. Each morning, Aunt Susan would find Ella's bed wet and with each passing day, she looked more embarrassed.

Cole's plan was working brilliantly. Ella was now experiencing what he had gone through. He waited for her to confess the truth.

One day, Ella finally broke down. She confessed her prank to Aunt Susan and apologized to Cole.

Aunt Susan was disappointed and made Ella apologize to Cole. She also decided that Ella would continue wearing diapers as punishment.

The roles had reversed and Cole enjoyed his freedom. He had taught Ella a valuable lesson and gained his respect back.

Summer ended, but the memory of the "Summer in Diapers" stayed. Ella never tried to prank Cole again and their bond strengthened.

The experience taught them both a valuable lesson: pranks might be fun, but not when they hurt someone's feelings. They became more considerate towards each other.

Every now and then, they would remember that summer and laugh about it together. It had become a funny story, a part of their childhood memories.

Aunt Susan also remembered the incident fondly. She was proud of how the situation had made her nephew and niece understand each other better.

And so, Cole's unexpected summer in diapers turned out to be a summer of learning, bonding and growing for both him and Ella.

They returned home and shared their adventures with their parents. Of course, excluding the diaper part. After all, some stories are best kept between siblings.
