It was a top-notch afternoon in Gotham city. Bruce Wayne, a 12-year-old boy was always the subject of mischief in Wayne Manor.

Selina Kyle, the 13-year-old girl next door played a foul prank on poor Bruce. She sneaked into Wayne Manor and found shy Bruce alone.

"Hello Brucey!" Selina greeted him, purposely using the nickname that Bruce disliked the most. Bruce only squeaked in response, looking quite embarrassed.

Selina's mischievous eyes flickered down to the sight of Bruce's childish tighty whities. A wicked grin spread across her face.

"Brucey, your underpants are so dorky!" Selina laughed. Bruce, being socially awkward, only blushed and squirmed without understanding why.

Selina saw that Bruce was completely puzzled. She decided to take her prank to the next level and gave Bruce a painful wedgie.

Bruce let out a yelp of surprise, his face turning red. Selina laughed uncontrollably thinking Bruce's reaction was adorable.

Following the wedgie, Selina continued the prank by leading Bruce to the bathroom. She had another idea, a swirly.

Bruce, being naive and innocent, had no idea what a swirly was. He got even more nervous and apprehensive about what was going to happen.

Selina gave an evil grin and dunked his head in the toilet, giving him a swirly. Bruce panicked and tried to free himself.

Just then, Alfred, the house butler, walked into the bathroom. He looked shocked seeing Bruce in such a state.

"What is going on here!" Alfred exclaimed. Selina retracted, trying to hold back her laughter. Bruce looked even more embarrassed.

Surprisingly, Alfred blamed Bruce for the whole situation. "Young Master Wayne, you should know better than this!" He scolded.

To Bruce's horror, Alfred decided to discipline him right there with a spanking. Bruce's eyes widened while Selina's laughter echoed.

Chanelling his strength, Bruce managed to break free from Alfred's hold. He ran away leaving Selina laughing and Alfred scolding.

Bruce didn't stop till he reached his room. He was embarrassed, but he couldn't help but laugh at the ridiculous situation.

On the other side, Selina was still chuckling. "That was fun Brucey," she murmured to herself, hoping for more such days.

Alfred, though stern, felt a bit sorry for Bruce but decided not to pamper the boy. After all, the prank was harmless fun.

Bruce was left wondering about the day's events. He made a pledge to himself to understand these pranks to avoid future embarrassments.

The mischievous Selina Kyle left Wayne Manor, promising to return for more fun. Bruce could only imagine what she had planned next.

That night, Bruce didn't sleep. He kept thinking about Selina's pranks and how he could escape them. A new day was going to dawn soon.

Selina, back at her own house, was planning newer pranks for Bruce. She found him adorable and wanted to see his innocent reactions.

Alfred, despite the day's events, ensured Bruce's safety and comfort. He had a feeling that things were going to change in Wayne Manor.

The next day, Bruce woke up with a sense of determination. He was still innocent, naive, but he was ready for what was to come.

Little did Bruce know that this was just the beginning of a series of adventures with Selina. Their story was just getting started.
