Jake knew he was virtually at the point of no return, that any second now and he'd be shooting cum all over his father, whether they liked it or not. Wisely choosing to prolong the experience, Jake (reluctantly, but firmly) grabbed his father's wrist and removed it from his cock. Before Roger could ask if everything was okay, Jake was on his knees, his now-trembling hands unbuckling his father's belt, unbuttoning and unzipping his father's trousers, sliding his father's briefs down his strong legs. Even though he'd caught a glimpse of it in the shower that time, and even though he'd felt its hardness pressing into his body, Jake hadn't fully comprehended his father's size. Now, mere centimetres away from his eyes, Jake could see every vein, every hair, every square inch of his father's cock - the cock that made him, the cock to which he literally owes his entire life - measuring in at around 7.5 hot, hard inches.
Almost too intimidated to continue, Jake knew he couldn't disappoint his father, not after last Saturday. Knowing he would be making daddy proud, Jake grabbed his father's cock with his right hand, and goddamn, they weren't joking about cocks being warm. Not jerking it, but keeping it very still indeed, Jake raised his mouth to his dad's cock and swallowed over 5 inches of it, his deep green eyes locked on his father's brown eyes. The saltiness of the pre-cum, the faintest hint of piss, and (again) the warmth all filled Jake's mouth, the musky, almost sweaty scent of his father's curly, unkempt pubic hair filled Jake's nose. Such a unique combination of flavours... All so delicious by individually; indescribable perfection when combined. Jake's lips clung tightly to Roger's dick and his tongue pressed against the underside of Roger's thick rod as he moved his head towards Roger's tip, and back down. Jake breathed heavily through his nose and moaned loudly with the back of his throat. Roger gazed deep into his son's eyes and ran his fingers through Jake's stylish hair.
"Jake... Oh fuck that feels good..." Roger moaned, clearly in ecstasy. It had been literal years since Lucy had given him oral, and never had she been this good. Yet here Jake was, his own beautiful son sucking his first ever dick, and doing it like a professional. Jake later told Roger that he'd practiced stopping his gag reflex using his toothbrush.
His father's ecstatic moan filled Jake with the confidence he needed to keep sucking, faster and with more tongue play. After reaching the head, Jake would release his suck-hold on Roger's cock and lick the tip in a circle once or twice before sucking down and up again. Soon, Jake realised his left hand was just sitting on his hip, so he decided to put it to work as well. He rubbed his father's tightly-clenched ass cheeks briefly, before becoming much more interested in his dad's hairy crack. His index finger completed a few up-and-down laps of Roger's crack before Jake started probing inside Roger's crack, where he quickly and instinctively found his father's tight, virgin asshole. Jake slid his finger inside, relishing the warmth, the constrictive pressure, and the forbidden appeal his father's ass offered. While he wasn't expecting Jake's finger, Roger nevertheless welcomed it with a deep, loud moan. Jake was still learning the art of pleasuring another man, and thus he wasn't entirely sure what he was meant to be searching for (yes, the prostate, but where?) once inside his dad's asshole. Not content to simply leave his finger there while he sucked his dad's cock, Jake began sliding his finger in and out of his dad's incredibly tight hole. Based on the now-rhythmic moaning escaping his father's throat, Jake decided that his dad didn't mind this improvisation too much. Still sucking his dad's thick, tasty cock.
But now, he was getting tired. His tongue was starting to get sore, his jaw and throat hurt from keeping them locked open. And Roger seemed no closer to cumming, which actually wasn't such a bad thing. But Jake knew he had to stop sucking, and soon. He slowly pulled his finger all the way from his dad's asshole, and completed one more cycle of suck-down/suck-up/tip-lick before kissing Roger's dick a temporary goodbye and standing up. Once again face-to-face with his (incredibly grateful and horny) father, Jake unbuttoned Roger's shirt, slid it from his shoulders, and was pleased to see his father wearing a plain white singlet, which Jake had always wanted to do, as he thought they were always sexy. He ran his hands over his almost-naked father, enjoying the feeling of the cotton singlet, then the top of Roger's hairy chest, then back to his singlet, then down to his hips and around to his (now relaxed) round ass cheeks. As far as 45 year old men go, Roger was the fucking sexiest in Jake's eyes. Roger started to lift his singlet, but Jake stopped him almost immediately.
"No, leave it, Dad... just this time," Jake pleaded. Roger reluctantly let go of the singlet, deciding to instead relieve Jake of his t-shirt, which was noticeably wet under the armpits. Apparently his son had been working hard down there. After the shirt was gone, Roger got the first good look at his son's naked body. Sure, he'd put on a little bit of muscle mass after doing all the yard work for his mother the last few months, but he was still quite a skinny young man. That just made Roger even happier; call him old-fashioned, but he still preferred the man being the more dominant one in the bedroom. And since that expression doesn't exactly apply to gay incest pairings, he liked it when the dad was on top the most. More experience, more assertive, more aware of what he likes. In Roger's eyes, Jake was still experimenting, and it was up to Roger to show him the ropes.
Roger placed a hand behind Jake's neck and pulled his naked, lustful, beautiful son closer to him, so that Jake was in line with his nipples. Knowing immediately what his dad wanted, Jake pulled the singlet to one side with a finger and licked his father's nipple keenly. It didn't take long for the nipple to become erect, at which point Jake started sucking. A short time later, he did the same for the other nipple. Soon, though, Roger's patience had reached its limit. He tapped Jake under his chin, indicating he wanted Jake to stand up properly again.
"I want you now, Jake." After that, there were no words. Roger simply placed his hands on Jake's shoulders, gave his son the briefest of kisses on his lips, and turned him around. Once again, Jake knew what Dad wanted without being told. He stepped towards the door, leaned forward and spread his legs for Roger. Lacking any form of packaged lubricant, Roger knelt on one knee, spread his son's firm, little round ass cheeks apart and began licking his asshole with vigour. Jake felt Roger's tongue slide up and down his ass crack, getting it nice and wet, and best of all, he felt his father's tongue lick his little brown hole in clockwise motions, counter-clockwise motions, and then an in-and-out probing that was almost painfully too brief.
Jake's disappointment would not last long, though, as his father was soon standing on both feet again, stepping closer and closer to Jake's standing, spread-eagled asshole. Roger held his cock steady with one hand and with the other, grasped Jake's shoulder for both purchase and to support his son through a painful time. Jake would later recall no pain at all, however. Despite being an anal virgin, his dad's cock entered him slowly, but with little resistance. Roger would later joke that Jake's asshole was clearly made for dad. The moment that Roger's thick purple dick tip slid fully into Jake's asshole, the pair were perfectly in sync. They moaned in unison, their masculine incestuous love filling their house's foyer and their hearts. As Roger pushed inside his son's constrictive-yet-accommodating rear passageway, Jake backed his ass further onto his father's thick, impossibly hard cock. He could almost feel each of his father's heartbeats in his ass as Roger's dick throbbed with unbridled passion. Eventually, Roger found his cock had been fully swallowed by Jake's fresh, eager asshole. His father's cock quickly brushed against Jake's prostate. Jake immediately thought "Oh, so THAT'S what I'm meant to look for inside dad's ass."
Comfortable in the knowledge that his son could fully take his sizeable dick this early into their relationship, Roger started thrusting. To Jake, this was a dream come true. The feeling of his father's almost total withdrawal, followed immediately by the smack of his dad's pubic bone hitting into his ass... God, it was ecstasy. Much better than even the best sex he'd had with Samantha. Yes, this is where Jake was meant to be: leaning against the front door while Roger fucked and pounded his back door. Roger's rhythm increased to a dizzying rate, yet Jake matched it without faltering. Soon, he felt Roger's rough hand around his hard cock as his dad fucked his ass and jerked his cock in perfect time. In and out of his ass, up and down his cock. Jake tried to scream out that this was all he ever wanted, that he was Roger's forever and ever, that he'd do anything for dad now. But the words never came. Jake's mind was blanketed in a hot, red haze of incestuous lust. All that remained of him at that moment was his primal instinct to fuck his dad's hard, hot, thick, long, delicious cock.
