Nick was sprawled out on the couch, his eyes glued to the screen of his phone. He was mindlessly scrolling through social media, bored out of his mind. Across the room, his five-year-old sister Kaylee was playing with her dolls on the floor.
"Nick, can we play a game?" Kaylee asked, looking up at her older brother with big, doe-eyes.
Nick sighed, feeling a twinge of annoyance. "Fine, what do you want to play?"
Kaylee's face lit up with excitement. "Let's play doctor! I'll be the patient and you can be the doctor."
Nick raised an eyebrow, feeling a little uneasy. "Uh, I don't know about that, Kaylee. That's a little weird."
But Kaylee was already stripping down to her underwear, giggling. Nick tried to look away, but his curiosity got the better of him. He couldn't help but steal a glance at his little sister's tiny body.
"Come on, Nick. You have to check me out to make sure I'm healthy," Kaylee said, pouting.
Nick sighed, feeling embarrassed. He took Kaylee's temperature and heartbeat, trying to keep his eyes focused on the thermometer and stethoscope. But it was hard to ignore the way Kaylee's underwear clung to her small hips.
"I have a special place that needs to be checked too," Kaylee whispered, pointing to her crotch.
Nick's heart skipped a beat. He didn't know what to do. He felt a mix of shock, confusion, and arousal.
"It's okay, Nick. I trust you. You can touch me there," Kaylee insisted.
Nick felt overwhelmed. He didn't want to hurt Kaylee or do anything wrong. But she was looking at him with such trust and innocence. He couldn't say no.
He tentatively touched Kaylee's crotch over her underwear. She moaned, encouraging him to keep going. He removed her underwear, revealing her bare pussy.
Nick's heart was pounding in his chest. He didn't know what to do. He felt like he was losing control.
"Go ahead, Nick. Put your thing inside me. I want to feel it," Kaylee said, spreading her legs wide open.
Nick felt a rush of adrenaline. He couldn't believe what was happening. He put his dick inside Kaylee's pussy, feeling a mix of guilt and pleasure.
Kaylee gasped, "It feels so big! Keep going, Nick."
Nick kept thrusting, feeling like he was committing a sin. But he couldn't stop. He was too far gone.
Kaylee came, moaning loudly. Nick followed, cumming inside her pussy.
They both lay there, panting and sweaty. Kaylee smiled, "That was fun! Can we do it again?"
Nick felt shocked and disgusted with himself. He pushed Kaylee away, not knowing what to say.
Kaylee looked hurt, "What's wrong, Nick? Why are you mad at me?"
Nick didn't know how to explain. He felt ashamed and confused. He just knew that he had crossed a line that he could never uncross.
