The treehouse in Nick's backyard had seen better days. The once vibrant paint was now chipped and faded, and the wooden planks groaned under the weight of the fourteen-year-old boy lounging inside. But Nick didn't mind. It was better than being stuck inside the house with his parents, who seemed to have forgotten that he existed.
He looked down at the yard and saw a splash of color amidst the green: Kalyee, the five-year-old girl from next door, was playing with her dolls. Nick watched as she made them talk to each other, her little voice rising and falling with excitement. He couldn't help but smile at her innocence.
"Hey, Kal!" Nick called out, leaning out of the treehouse. Kalyee looked up, her eyes wide with surprise. She hesitated for a moment before climbing up the ladder.
"What are you doing?" Nick asked as she approached him, her dolls clutched tightly in her arms.
"Playing house," Kalyee replied shyly.
Nick rolled his eyes. "You're still playing house? You're such a baby."
Kalyee stuck her tongue out at him. "You're a stinky boy."
Nick laughed. "You don't know anything about being a grown-up."
Kalyee challenged him. "Then teach me something 'grown-up'."
Nick thought for a moment before his face lit up with a mischievous grin. "Okay, I'll teach you how to kiss like a big kid."
Kalyee looked skeptical but Nick assured her that it was no big deal. He leaned in and demonstrated a quick peck on the cheek. Kalyee giggled and asked for another one.
This time, Nick exaggerated the kiss, making a loud smacking sound. Kalyee laughed and asked for one more.
Nick leaned in again, but this time he moved his head towards Kalyee's neck. Kalyee squealed and tried to pull away, but Nick held her still.
He started to nibble on Kalyee's neck, making her giggle and squirm. Kalyee playfully punched Nick and told him to stop being so silly.
But Nick wasn't done yet. He pulled away and looked at Kalyee with a mischievous glint in his eye. He unzipped his pants, pulling out his penis.
Kalyee's eyes widened and she started to protest, but Nick shushed her and told her that it was just another way that grown-ups kissed.
Nick guided Kalyee's head towards his penis and told her to "kiss it like a big kid." Kalyee hesitated but then tentatively licked the tip of Nick's penis.
Nick moaned and told Kalyee that she was a quick learner. He grabbed the back of Kalyee's head and pushed her down further, making her take more of him in her mouth.
Kalyee started to gag but Nick didn't seem to notice. He thrust his hips up, pushing himself deeper into Kalyee's mouth.
Kalyee pulled away, gasping for air. Nick looked at her with a satisfied grin and told her that she did a good job.
Kalyee wiped her mouth with the back of her hand and glared at Nick. She called him a "gross boy" and threatened to tell on him.
Nick just laughed and pulled Kalyee into a hug. He told her that she was his favorite little sister and that he'd always teach her new things.
Kalyee rolled her eyes and pushed Nick away. She told him that he wasn't her brother and that she was never playing "house" with him again.
Nick just grinned and watched as Kalyee climbed down the ladder, already planning his next lesson.
