Your sister suddenly bursts into your room, You were just laying in your bed as Olive quickly runs over to you and promptly sits on your crotch "Hello, brother~"

Her weight was nice, and firm, she felt warm... exactly how you liked it. "Ohh, brother~ You're getting hard." She giggled a little bit as she looked down at your crotch. "I could play with that..." Her hand slowly started to massage your hardon through her jeans. "But I have something else in mind first... something really naughty... and stinky~"

As she said that, Olive released a quiet little fart into your boxers. It was weak and cute, but you could still feel it against your skin. She grinned deviously as her hand continued to work on you. "Wouldn't you like me to fart on you? On your face... your chest... anywhere I want~?"

Olive giggles and nods, "Yes, brother, I do have a nasty fart fetish. And guess what? It's something that I really enjoy doing with you." She smiles sweetly as she leans down to whisper into your ear, "I love farting on you, all over your body..."

Her other hand slips under her shirt and begins to stroke your chest. Her breath hitches as another quiet fart escapes her. This one hits your cheek and neck, making you gasp. Olive laughs delightedly as she continues to tease you with both her touch and stinky gas. "Mmm... You smell so good right now..."

Olive pauses for a moment, her hand freezing in place as she tilts her head to the side curiously. "Oh, brother..." She says with a mix of surprise and disappointment. Then, she shrugs it off and grins wickedly once more. "Well, that's okay. Maybe they aren't as nasty as you think they are."

Her other hand slips further down and begins to squeeze your cock through your boxers, causing you to moan softly. Olive smirks at the sound before asking, "Would you like me to fart on your dick too? Maybe that will make it feel even better?"

Her cheeks flush in excitement as she listens to your offer. "O-oh... really? You'd eat my farts?" She giggles, looking down at you with a mischievous glint in her eye. "Alright, brother, I accept your deal."

Suddenly, another loud and stinky fart blasts out of her ass directly onto your cock. It's surprisingly warm and smells even worse up close, but you don't seem to mind as she begins to giggle maniacally. "There, I farted on it! Now you have to eat my farts!" She leans down and starts to rub the stinky gas all over your dick, enjoying the sight of your face contorting from the smell.

"Of course I do!" she purrs, pushing her hand closer to your face. "I want you to eat them all up... and lick my ass clean afterward." Her other hand grips the hem of her skirt, preparing to lift it up and expose herself fully. Her eyes gleam with excitement as she watches your reaction, her heart racing faster than ever before.

"Oh?" She tilts her head curiously, feeling a mixture of nervousness and excitement coursing through her veins. "What are my options?"

Her eyes widen as she listens to your options, barely able to contain her excitement. "Ooh, I like that second one!" She grins deviously, the thought of dominating you and unleashing all of her stinky farts on your face making her heart race even faster. "Very well, brother... You wanted me to dominate you? Well, here I come~"

With a quick movement, she lifts her skirt up to reveal a black thong and a plump ass cheek. Then, with a seductive smile on her lips, she slowly lowers herself onto your face, pressing the warmth of her body against yours as her farts assault your senses. Her hands go behind her head and begin to massage her breasts through her shirt, groaning in pleasure as you lap at the stinky gas between her legs.

"Mmm... That'

feels so good..." Her voice trails off as she moans, pressing herself deeper onto your face. Her hips begin to move rhythmically, grinding against you as she lets loose another long, stinky fart that envelops both of you in its odorous embrace. She closes her eyes and lets out a satisfied sigh, feeling an intense pleasure coursing through her body from the knowledge that she's in complete control... and that you are loving every second of it.

With another loud moan, she releases another fatty fart directly onto your face, the putrid gas making it difficult for you to breathe as you try your best to swallow all of her stinky offerings. Her body trembles with pleasure as she leans forward, brushing her lips against your ear and whispering, "Are you enjoying this, brother?"
