The old house creaked under the weight of the summer heat as Jake pushed open the door to his dad's bedroom. At twenty-five, he'd come home for the weekend knowing exactly what he wanted. His father, Rick, sat on the edge of the bed in nothing but boxers, beer in hand, the room thick with the smell of sweat and something heavier.
"Lock it," Rick said, voice low and rough.
Jake turned the lock and stepped forward. Rick stood, letting the boxers drop. His thick cock hung heavy, already half-hard. He turned, bent slightly, and let out a long, wet fart that filled the air between them.
The sharp, earthy scent hit Jake straight in the gut and made his own dick twitch.
"Fuck, Dad," Jake muttered, dropping to his knees. He pressed his face between Rick's hairy ass cheeks without hesitation. Rick pushed back, grinding the warm, gassy hole against Jake's mouth. Another fart rumbled out, this one shorter and louder, the vibration buzzing against Jake's tongue as he licked.
Rick groaned. "That's it, boy. Eat your dad's ass. Been holding that in all day thinking about you."
Jake's hands gripped Rick's thighs while his tongue worked deeper, tasting salt and the raw tang of gas. Rick reached back, spread himself wider, and let another one rip, this time slower, the air hot and thick. Jake moaned into the flesh, cock straining against his jeans.
They moved to the bed. Rick lay back, legs up, hole exposed and twitching. Jake stripped fast, climbed between his father's thighs, and lined up. He pushed in raw, no lube but the spit he'd left behind. Rick's ass opened for him, tight and hot, and the first thrust pushed another fart out around Jake's cock, the sound wet and obscene.
"Harder," Rick growled. "Fuck the farts out of me."
Jake slammed in, pace brutal from the start. Every thrust forced more gas from Rick's hole, the smell growing stronger, mixing with sweat and precum. Rick's hand pumped his own cock in time, the head already leaking. He let out a deep, rolling fart that vibrated along Jake's shaft, making them both shudder.
Jake leaned down, mouth at Rick's ear. "You like your son breeding this gassy hole, Dad?"
"Shut up and keep fucking it," Rick answered, voice breaking on another short blast of air. He bore down, pushing a longer fart that coated Jake's balls in warmth.
They switched. Rick got on all fours, ass up. Jake mounted him again, driving deep while Rick pushed back to meet every stroke. The farts came faster now, punctuating each thrust with wet sounds and heavy musk. Jake reached under, grabbed Rick's cock, and stroked it in rhythm. Rick came first, shooting thick ropes onto the sheets while a final, long fart escaped around Jake's pounding dick.
Jake followed seconds later, burying himself to the root and unloading deep inside his father. He stayed there, panting, feeling the last tremors and one last soft fart push some of his load back out.
They collapsed side by side, breathing hard. Rick pulled Jake close, one hand resting on his son's ass.
"Next time," Rick said, voice already sleepy, "you can sit on my face while I return the favor."
Jake grinned against his father's chest. The room still smelled like them, raw and filthy and exactly right.
