Amanda had teased her big brother David for years, but never like this. Ever since she turned sixteen, she noticed the way he watched her when he thought she wasn't looking. She'd caught him staring at her ass more than once, and she knew it turned him on. So when she started dating that new guy who introduces her to kinks and fetishes online, she couldn't resist turning the tables on her own sweet-assed sibling.
One night after dinner, Amanda slipped into her room, stripped down to her white cotton panties, and started her dirty work. She slid her index finger inside the crotch of her panties and began rubbing herself, imagining it was her brother's face pressed between her legs. Even better, she knew he was out there somewhere, smelling her through the walls. That made her even wetter than usual.
When she was good and worked up, Amanda walked out into the living room where David was sitting on the couch. He nearly jumped out of his skin when he saw her walk past, ass wiggling as she went. She cansey whistled tunelessly as she headed to the bathroom, her tight little behind swaying like a belly dancer's.
David couldn't believe what he was seeing, but he also couldn't look away. He leaned forward on the couch, desperate to catch a whiff of his sister's warm, musky scent. To his delight, he caught a tantalizing waft of her pheromones as she disappeared around the corner.
Amanda stood in front of the toilet, lowering her panties to her knees. She gasped as a fresh wave of pleasure washed over her, her body shaking with suppressed ecstasy. She took a long breath, letting it out slowly, and then let another one slip passed her lips. It was a short, sharp fart but it was enough to make the hairs on David's arms stand on end.
With a devilish grin, Amanda lifted her ass high into the air, giving her brother an eyeful of her Round of Applause. She shuddered as another round of pleasure rippled through her, this one even wetter and more powerful than before. She knew exactly how much she was turning him on, and it was exhilarating.
Satisfied for now, Amanda pushed her panties back up and flushed the toilet, her head held high like a true queen. She walked back out to the living room, her hips swinging side to side in a hypnotic rhythm. David was transfixed, unable to look away from his gorgeous little sister who was teasing him so mercilessly.
Finally, Amanda stopped right in front of him and pulled her panties to the side, revealing a dark stain that told him exactly what she'd been doing in there. Her gaze locked with his, daring him to say anything. But all David could do was nod, his heart pounding in his chest.
"Good boy," she said with a smile, knowing exactly how much she had him wrapped around her finger. With that, she turned around and strutted back to her room, leaving David sitting there with the most delicious mixture of shame, desire, and arousal he'd ever felt.
