Jake had just turned twenty-two when it started. His dad, Rick, was forty-six, still built like the construction worker he was, thick arms, broad chest, and an ass that filled out his work jeans in a way that made Jake stare too long. They lived alone after Jake's mom left years ago. Late one night after too many beers, Rick admitted he liked getting fucked. Jake's cock got hard instantly. He didn't hesitate. "Show me, Dad."
Rick stripped right there in the living room. He bent over the arm of the couch, spread his cheeks, and showed Jake his hairy hole. "Been thinking about your dick, son. Want you to wreck it." Jake dropped his pants and shoved two fingers in dry. Rick grunted but pushed back. "More. Finger-fuck your dad's ass."
Jake spat on his hand and worked three fingers in, twisting them open. Rick moaned like a slut, hole clenching around his son's knuckles. "That's it, boy. Stretch Daddy's cunt." Jake pulled his fingers out, lined up his thick eight-inch cock, and slammed in balls-deep in one thrust. Rick yelled, but it was pure want.

Jake started pounding, gripping his dad's hips, watching that fat ass ripple with every slam.
"Fuck, Dad, your hole's greedy," Jake growled. He fucked him hard and fast, no mercy. Rick reached back and spread himself wider. "Use it. Breed your father's ass." Jake's balls slapped against Rick's taint. Sweat dripped down his chest. He pulled out to the head and rammed back in, making Rick's hole gape and suck him back. Rick's own cock hung heavy and dripping, untouched, swinging with every thrust.
They moved to the bedroom. Rick got on his back, legs pulled to his chest. Jake climbed on top and buried his cock again. He leaned down and kissed his dad rough, tongues fighting while he drilled deep. "Tell me how much you love your son's cock," Jake demanded. "Love it, son. Love getting fucked by my own boy. Fill me up." Jake hammered faster, the bed creaking. Rick's hole made wet, filthy sounds around the shaft. Jake reached down and stroked his dad's leaking dick in time with his thrusts.
After a while Jake flipped him again. Doggy style on the bed this time. He spat on Rick's hole and drove back in. "Arch that back, Dad. Show me how bad you want it." Rick did, pushing his ass up high. Jake grabbed a handful of his dad's hair and yanked while he fucked. His hips slapped loud and steady. Rick begged for more, voice hoarse. "Harder, Jake. Destroy Daddy's hole."
Jake pulled out and made Rick suck him clean, watching his dad taste his own ass on his son's cock. Then he pushed Rick onto his side and slid back in from behind, one leg hooked over his arm. He reached around and pinched Rick's nipples while he pumped. Rick's hole fluttered and tightened. "Gonna come, son. Fuck it out of me." Jake pounded through the orgasm, Rick's cock shooting untouched onto the sheets. The clenching pulled Jake over the edge. He buried deep and unloaded, flooding his dad's guts with thick ropes of cum.
They stayed locked together, breathing hard. Jake's cum leaked out around his softening cock. Rick reached back and scooped some up, licking it off his fingers. "Again," he said. Jake's dick twitched back to life inside him. Round two was slower but just as filthy, Jake making his dad ride him reverse, watching that cum-slick hole swallow his cock over and over. By morning Rick's ass was red, puffy, and still hungry. Jake promised to keep it that way every night from then on.
