Bobby lay sprawled out on his bed, the summer sun streaming in through his window. He let out a bored sigh, his mind wandering as he searched for something to do. That's when he heard it - a soft giggle coming from the other side of his door. He sat up, intrigued, and saw a flash of dark hair as his little sister, Lucy, peeked in.
"Hey, Bobby!" she called out, her voice full of mischief. "Wanna tickle fight?"
Bobby rolled his eyes, but couldn't help but smile. Lucy had always been a force to be reckoned with, even at just ten years old. He swung his legs over the side of the bed and stood up, ready for a challenge.
As they wrestled on the bed, Bobby couldn't help but notice the way Lucy's shirt had ridden up, revealing her smooth, tanned stomach. He felt a strange sensation in his pants and tried to ignore it, but Lucy was quick to pick up on his discomfort.
"Hey, Bobby," she said, her voice low and teasing. "What's that in your pants? You got a boner?"
Bobby's face turned bright red, and he tried to change the subject. But Lucy was relentless.
"Come on, Bobby," she said, her eyes sparkling with curiosity. "Show me what a boner looks like."
Bobby refused, but Lucy wasn't taking no for an answer. She grabbed the waistband of his pants and pulled them down, revealing his erection. Lucy's eyes widened in surprise, but she didn't look away.
"Does it hurt?" she asked, her voice soft.
Bobby nodded, trying to pull his pants back up. But Lucy was curious. She reached out and gently touched his erection, and Bobby gasped in pleasure.
"Does it feel good?" Lucy asked, her eyes locked on his.
Bobby nodded again, unable to find his voice. Lucy's mischievous grin grew wider as she climbed on top of him and started to grind against him. Bobby couldn't help but moan in pleasure as Lucy took things further, riding him until they both reached their climax.
Afterward, Lucy got off him and pulled up her pants, leaving Bobby lying there, stunned. She looked down at him with a playful insult.
"You're wrapped around my finger, Bobby," she said, her voice full of satisfaction. "And I'll never tell anyone about what just happened."
Bobby couldn't help but agree, still in shock over what had just happened. But as he lay there, he couldn't deny the thrill that coursed through him. It was a forbidden fruit, but one that he couldn't help but want more of.
