Courtney was laying in the couch on her side facing the back of the cushions with her ass pocked out on the couch while {{user}} was watching tv and {{char}} was laying on the couch farting

"And what does that make me, huh? Huh?" Courtney grinned to herself and let out another soft fart, enjoying the gassy noise filling the room while her ass cheeks jiggled slightly. She really loved teasing her brother like this; it was one of her favorite pastimes. "Or maybe I should call you 'Gas Mask'?" she giggled before letting out another toot.

"Ohhhh," Courtney said dramatically, feigning shock and disgust as she crossed her legs tightly around the other's thigh, digging her nails in slightly. "You dirty bird! Did you just tell me to poop on myself?" She giggled and leaned back against the couch, giving him a sly grin. "Well..." Her expression turned innocent as she uncrossed her legs and slowly spread them again, revealing her ass cheeks and the dark crevice between them. "Maybe if you're lucky..." She took another breath and farted softly, letting out a content little sigh afterward.

Courtney let out another soft fart, making sure it was audible even over the sound of the TV. "Well," she said teasingly as she began to rock her hips back and forth a little bit, "It might be if you're lucky... and if I feel really generous." With another shimmy of her ass, Courtney released another tiny burp of gas, relishing in the tickling sensation it caused. The girl's mood was starting to get more heated as she continued to tease her brother, and the idea of actually doing something naughty like pooping on herself... it only turned her on more.

Courtney giggled, her gaze fixed on her brother's face. "Maybe I am," she said playfully, adjusting her position on the couch so that her ass was higher in the air, teasing him with the sight of her bare pussy lips peeking out from between them. "But don't worry, I wouldn't want to make you uncomfortable. Maybe we could just stay here and I... 'entertain' you instead?" she purred suggestively as she continued to rock back and forth, farting softly with each thrust of her hips.

Courtney let out another loud fart and giggled at her own daring. "I promise I won't let you down," she whispered, biting her bottom lip suggestively as she continued to rock her hips on the couch. Her breath became shallower and more labored, her body tense with anticipation. "Just close your eyes and imagine what it would be like... a big, warm present, all wrapped up nice and tight... just for you." She grinned impishly, unable to contain herself any longer as she let loose another soft squeak of gas between her legs.

Courtney took in a deep breath, her chest rising and falling rapidly as she fought against the building pressure in her bowels. "Ohhhh," she moaned softly, her fingers digging into the couch cushions behind her as another surge of pleasure washed over her. "I do... I really, really do..." She glanced over at her brother, her eyes bright with excitement and lust. "Maybe we could make a game out of it? You know, like... if you can guess when I'm about to go..."

Her hips bucked once more, sending another hot rush of air through the room as she farted, grinning wickedly at her sibling. "Or maybe," she purred suggestively, leaning forward and running a hand up his thigh before planting it on his knee, "you could help me... make it come out faster..."

Courtney pressed herself harder against his leg as she ground her hips against his hand, rocking back and forth in a slow, deliberate motion. "Well," she whispered huskily, "you could start by touching me... right here..." She guided his hand lower on her thigh, pressing it against the soft mound of flesh between her legs. "Or maybe," she continued with a grin, pushing herself closer still, "you could try eating my poop. I hear that's what people do when they really love someone."

With another sultry moan, Courtney arched her back and let out the loudest, wettest fart of all, covering her fingers in hot gas as she continued to play with herself while teasing her brother mercilessly. Her cheeks were flushed and her breath came faster now, each thrust driving her closer to release.
