For Dad's 50th birthday, I'm thinking that letting him fuck me would be a fun present.

Of course, that isn't ALL I'm getting him. For starters, slung over my shoulder, the tailored suit I picked out for him on my trip was a bit crumpled from the airplane ride, but otherwise perfect. I'm sure he was still going to give me a lecture on taking care of my things as if I were nine, but after 21 days away from him, it was more than welcome. Each trip away from him was already a test of my endurance, which I sometimes passed and sometimes failed. It's why I originally invited him to come along with me, all on company dime to boot, but he kept refusing in that indifferent way only dads can pull off. 

"..ter! Peter! PETE!"

I’m so busy daydreaming of all the things I want to do to him that his deep voice, cutting through the airport traffic, catches me off guard.

"Dad?"

"Jesus! Where was your mind off to? I've been following you since you came through the reception area!"

I let the bags in my other hand fall to the ground as I meet him halfway. We hug immediately, strong and messy as I tighten my muscles around him.

"I missed you so much, Dad!" I exhale into his shoulder.

"I missed you as well, Pete."

We stay entangled for a moment, his hand clenching and unclenching on my back. When we eventually let go, he gives me a longing smile and plants a kiss on my forehead. He's still in public dad mode, but I can see his eyes simmering, the toll of our time apart apparent in them.

"I want to go home. Right now," I say, squeezing his hand.

Dad nods, clearly on the same page. "You got all your stuff?"

"Yeah."

"Then let's go."

He grabs my bags before I can, and I keep my arm on his shoulder all the way to the car. We don't say much on the way home aside from Dad checking on my health and sleep while my hand rests at the bottom of his back, rubbing at the cleft of his ass.

"Pull over."

"No. We're almost home."

"Come on, Dad. I'm about ready to bust in my pants," I plead, my middle finger finding his sweaty hole.

"One of us has to have some self-control." He tries to remain composed, but squirms over my fingers nonetheless while staying focused on driving.

I lean to his side and give his earlobe a quick lick and bite. "Do we really?" I coo in his ears.

"Jesus, Pete!" His face is visibly contorted now. "Did Italy run out of beefy bottoms or something?"

"I've been saving it all up for you, Dad. No one is worth my cum more than you." I tell him, half-true and half-horny.

"I bet you say that to all the dads you fuck," Dad mutters under his breath, eyes focused somewhere ahead.

When he steals a glance at me, I lock our lips for a quick kiss. It's dangerous for many reasons, but I can't sit still with how horny I feel. He kisses me back, then turns back to face the road right away through no want of his own.

"Peter."

His voice is stern, and I ease down a bit.

"Sorry, Dad." I apologize with a kiss on his cheek. "Guess you're right. We do need one of us to stay cool."

"Glad you understand."

I slump back in my seat and try to busy myself with the passing scenery.

"Alright, alright, tiger. Let me give you a helping hand." Dad chuckles and reaches out his hand, cupping my crotch.

"Fuck, Dad. I don't wanna come from a handjob."

"Who said anything about a handjob? I'm just keeping your engine going till we get home."

He cups my balls, touching me in the way only he can and sending shivers throughout my body.

"Fuck," I curse again, rapping my hand against the car door as Dad expertly palms his way around my dick, poking at his favorite toy. "Drive faster."

"You got it."

I bite the base of my finger to keep myself calm as Dad slams down the gas pedal.

*****

The moment we get home, I'm on him with an animal's ferocity. My tongue burrows into his mouth, sucking up every inch of it like it's precious air. Dad barely shuts the door before I slam him against it. Our straining bulges bounce off each other's, and Dad moans into my mouth, his own tongue at the mercy of my oral invasion.

His hands are busy unbuckling my dress pants while mine tear at his ass cheeks through the straining fabric.

"You've been hitting the gym, Dad?" I say while sucking on his neck, trying to leave a mark that'll last all week.

"A little surprise for my boy," he laughs, out of breath, his head tilting backwards.

"Fuck..." I squeeze harder as I feel my cock spew some of its juice into my underwear. "Bedroom. Quickly."

Dad doesn't need to be told twice as he climbs on me, locking his legs around me with practiced strength. When I first told Dad how I wanted to fuck him standing, he dismissed it at the thought of accidentally blowing out a knee or something of the sort, but after a couple of good, focused dickings, he was more open to the idea and even ended up loving the way it poked out his insides.

At 50 years old, Nate Hawkins was a prime example of old muscle. His body, honed with that everyday work of a blue-collar man, struggled to contain his strength in its folds, and the sight of all that DILF meat mounting my front was enough fuel for me to carry him to the moon and back.

Holding him by his muscular cheeks for dear life while he frots his own thick dad cock against my abs, I run to our bedroom and lay him down gently.

"How do you want me, Pete?"

He's breathing heavily and giving me those "fuck me" doe eyes, and I freeze as the possibilities flood my mind. I'm so hungry for my own dad, I don't know which part to fuck or bite or kiss. His soft pecs, big and round, rise with every breath, and his full torso is basically begging to be held and abused. The whole body being dusted with salt and pepper hair, even his thick, log-like limbs, is just the cherry on top.

"I need to blow one fast, Dad. Hang your head off the edge of the bed."

He nods and shimmies his mass of muscles to the edge while I circle around. I position myself on top of his head, my legs sandwiching it while he relaxes into my quads, his own meat relaxing on his thigh, thick and leaking.

"Take it off."

"Right away, Son."

His voice is full of nothing but compliance as he works my boxers and frees my cock, rewarding him with a hearty slap across his face as it springs free. His laugh is so pure, I end up laughing along while he gives it kisses and licks.

"I missed it so much, Pete," he says gleefully.

"You missed your own son's dick, Dad? You missed my fat pole?" I lay on the smug act, letting myself enjoy his hunger.

"Sure did, stud. I made it after all, and now it's my own flesh dildo whenever I want."

Like most stuff we did, Dad didn't initially agree, but went all in once he got a taste of how sweet incest sex can get. He spent a good chunk of his life denying his urges, and I was always happy to fill his needs with my cock.

"Yeah, Dad. It's all yours. Your own son wants nothing more than to spend every waking hour in your warm holes."

I give his lazy dick a few tugs as his legs jerk in response.

"Fuck me, Son. Take my mouth however you want."

I can't hold back anymore. I position the head to his lips (which he kisses again, like he's making out with it) and push inside. It slides in with barely any resistance.

"Fuuuuuuck, Dad! Not just the gym? You've been practicing with that dildo as well?"

My question goes unanswered on account of half my cock down his throat. He gargles a response around it, and I retreat to let him adjust.

"I told you, Pete. I wanted to surprise you." His words come out with spit and drool as it collects around his mouth.

"Best fucking surprise," I say as I dive back in.

It takes a couple of attempts, and Dad finally gets my whole length down his throat, the blunt head pushing against its back. My balls get squished between my crotch and his nose, effectively sealing his airway with my own musk, the sweat from my long trip working its way into his brain by now and sending him into cock heaven. I push further, shaking my hips sideways as I grind his head into the bed, enjoying the feeling of his warm insides as they contract around my cock.

It's not long before he taps out, and I unsheath my dick from his mouth, marveling at how it even worked its way inside in the first place. He takes deep breaths while all the fluids flow down his face, and my dick twitches at the sight, causing me to re-enter him. He doesn't complain and takes it like a champ, once again getting his face stuffed with my crotch. We repeat this a couple of times, and by then I'm ready to blow.

"Ready for the first load of the day, Dad?" I ask him with a laugh, fully knowing he can't respond.

He squeezes my thighs, his sign for 'keep going', and I start slamming into him repeatedly. He manages to catch short breaths in between, but otherwise holds for as long as he can until I lock into him.

"Take it! Take it, Dad! Swallow your grandchildren! The sperm of your own offspring!" I yell out whatever obscenities that come to mind as I unload in him, sending my warm load through his esophagus and deep into his stomach.

His grip is ironclad on either side of me as he tries his best to swallow it all. There's no way to savor it at the moment, but he seems determined to drink it all nonetheless. It doesn't go this way, though, and some of my sperm dribbles down along with his saliva, painting his face in pretty white.

Once I cum, something in me snaps, and I back away before lying back in the middle of the bed. Dad crawls up to my side, and I bring his face in for a make-out. It's wet and sticky and reeks of musk, and I wouldn't have it any other way. I kiss the insides of his mouth and lick around it, collecting the drops of his effort as we trade them between us.

"God, I've missed you," he lets out the word of longing he's been holding since the airport.

"You should've come along. We could've fucked all over Europe for that matter."

"I told you I can't compete with you youngsters anymore." His tone is wistful, and the fact that I know it's all in his head drives me crazy.

"That's not true, Dad!" I try to defend him from himself.

My dick, slimy with Dad's effort and my own cum, starts chubbing back up, and that proves more interesting to my father than a domestic argument.

"You got another one in ya, tiger?" Dad smiles at me, kissing around my face while playing with my cock like a squeeze toy.

"Fuck." I can't resist him when he gets cock-crazy like this. "You know it. I wanna get back inside you right now."

I grab his pecs, then pinch his nipples, and he lets out a moan.

"My own son wants to breed his dad," he says, biting his lip, "I can't possibly be prouder of you, Son."

He goes down on me, nursing on my cock like he's trying to get every single drop still in it, and cleaning it in the process.

"You're the fucking best, Dad. I'm the luckiest son in the world. I get to have you whenever I want."

The combination of oral cock warming and verbal play gets to me, and I flip over and raise his legs until his knees can't bend anymore, spreading him like a doughy, human pretzel. Giving more time for my dick to recuperate, I go down on Dad, prying open the fuzzy, firm butt and giving his pink hole a few licks.

"Ohhh.. Oh, fuckk..." His voice guides me as I tongue him with years-long expertise.

It wasn't even a month away, but it feels like forever since I gave him a proper rim job, and the feeling of his man sweat on my nose and his cooperative hole on my mouth really drives in the feeling of being home.

"Push out."

Dad obeys right away, letting his lips relax outwards. I get close and lay gentle pecks on them before starting to munch down as if I'm frenching his mouth, slipping my tongue inside as much as possible.

"I need to fuck you. I need to blow another load right fucking now." I announce. My cock, which was staining the sheets with precum, is already knocking at his door.

He nods, his eyes hungrier than ever, and I start digging into his guts. It takes little time before I'm buried to the hilt, and he's moaning like his whole body's in heat. The sight of him, full of cock and on cloud nine, gets me going harder.

"Missed your son's cock, didn't ya, Dad?"

"Ahaaa..." He manages to utter a confirmation before being reduced to more gasps and moans as my fuck stick digs into his insides.

"Nothing like that dusty old piece you practiced with, is it?"

"Naaa... Nothing like it.... Oh, God... It's so big, Pete. Don't stop!"

"Nothing can pry me away from you, now, Dad. I'm going to fucking breed you till my sperm seeps through your walls, you hear me?"

Dad responds by digging his fingers into my broad back with a primal lust. Feeding off his grip, both hands and hole, I start picking up the rhythm. Slow at first, drawing out his pleasure as his anal chute tries to milk my cock for all its worth, then much faster, hammering into him with the sole intention of rearranging his guts. My balls dance between his legs as I bring them down full force with each thrust, the mattress fighting for its life under us. The room is filled with the sounds of sex, from wet skin slapping to the occasional sound of Dad's asshole getting resized again.

I can't even put on a verbal show as I get close to cumming, the feeling of my Dad's hole pushing out against me, allowing me to punch his prostate over and over, guiding me to my nut. He's obviously gone as his head rocks with every thrust, struggling to even close his mouth as more and more lewd noises escape from it.

With one final dig, I see stars as my cock explodes inside him, altering his internal biology with my own. And as if that wasn't enough, Dad's whole body seizes up, and his legs lock around me, in what I call baby-making sex position, as he yells out.

"Fuck!Fuck!Fuck!Fuckkkk!"

His anal muscles clamp down on my dick like a hydraulic press, trying to keep the head pressed full force against his love button. I yell out alongside him, the stimulation exceeding anything I can imagine and making me feel like my soul was currently shooting through my cockhead. Even when I try to move, he stays tangled around me, refusing to let me withdraw an inch.

It's an insane moment, but it still passes, and eventually, we collapse back into the bed. My dick finally goes down, spent for good this time, and Dad lies in my arms, his beefy body against my own and his hole comfortably leaking onto our sheets. I'm still in a sex haze as I finally speak again.

"You missed getting bred with your own son's seed? Your flesh and blood making you cum from your ass?"

"More than anything. My hole never felt better."

I look over at his blissfully happy face, and I can see his Dad instincts clear as day. It warms my heart to finally be back in his arms, where the entire world means nothing except for him.

"You take it so well, Dad. My cock was made for it after all."

He cozies up to me, burying his face in my pecs.

"Glad you're back, Pete. The house was cold without you. Too cold."

"Glad to be back as well, Dad!"

I kiss his forehead and hug him tight as I slowly drift into a much-needed sleep after a very, very long day, failing to notice the look he gives me as I do so.

*****

I wake up to near total darkness. It must've been 2 or 3 in the morning without so much as a hush in the world. Some light breaks into our room from the door that was left ajar and brings to my eyes Dad's peaceful face, gazing at me from my chest.

I pull him in for a quick kiss. "How long have you been up?"

"Not long. I thought of waking you up with a blowjob, but you seemed so peaceful."

"You know it's your birthday today, not mine, right?"

He laughs. "All the more reason to prove I still got it."

"You definitely do, Dad. Happy 50th birthday, baby." I bring him in for another kiss before stopping. "It is the 28th already, right?"

"Hahahaha. Yes, it's my birthday now. Happy 50th to me," he says, witsfully once more.

"Hey, come on, I thought you promised you wouldn't be like that. If yesterday was anything to go by, you're even better now than when we started!"

"Thanks, Pete. I appreciate it, I really do, and I know you mean it. But I can't just shake off that feeling whenever I look in the mirror."

"You gotta wait till you try on your new suit. I dare you to tell me you're feeling your age then."

"What new s- Is it the one you had with you at the airport?"

"Yeah, silly. You think I brought one back for me?"

His eyebrows knot. "Pete, you shouldn't have. You know I d-"

"Come onnnn, Dad! I wanna treat my husband now, and fuck it if I'll let you convince me otherwise."

Dad and I have been married in all ways except official for the past nine years, and while we never skimp on each other, we still kept our finances separate. He still held on to the old-school mindset of keeping your accounts strictly professional, even within family. He also held on to the stupid belief that I shouldn't limit myself to my parents' world, which translated in our relationship to not settling down for him. I always try to get him to snap out of it, to realize his pace can be just as fast as mine, and he always goes with it so long before faltering.

Meanwhile, Dad's brows relax, and an easy grin reappears on his face as he lies on my chest once again.

"You're too good to me, Pete..."

"Bullshit, I'm just indulging myself with my Dad. If anything, you're the one who's too good for me, always putting out whenever and however I feel like it!"

"It's hard to say no to such a stud," he says, kissing my nipple and licking around my muscular chest, "which reminds me. Did the stud have fun in Italy?"

His words aren't accusatory but playful. He plays with my dick absentmindedly while waiting for the answer. I give his back a hearty rub.

"You know I'd tell you before I picked up another guy, Dad."

"I wouldn't be mad. I like it when my boy spreads the family seed, and I like it when he keeps it in the family. Honestly, just seeing you fuck is enough for me."

"You know... I'd love to spread the family seed with you one day..."

"Pete..."

I sigh. "As long as you're happy, Dad."

A moment of quiet, then Dad suddenly switches channels.

"Do you not remember how I taught you to store a suit? Why was the bag all scrunched up?"

"Oh, dear God. I'm sorry! I promise I won't forget to do it next time."

"You said that last time."

"And I'm saying it again now. Forgive me? Pretty please?"

He gives a dad grunt and lets it go, thankfully.

"The good news is, your second gift doesn't wrinkle!"

He turns around, equally interested and cautious. "What did you get this time? I'm not wearing a buttplug 24/7, no matter how much you ask."

"HAHAHAHAHA... No, it's not that."

I reach around to the side of the bed, where my bag was dropped carelessly last night, and fish out a blister pack.

"Peter Nathaniel Hawkins," his voice shoots straight out, "did you bring drugs into our house?"

"WHAT? NO! Dad! Honestly..." I pinch his furry cheek and try to dissolve his shock, "It's Viagra! Homemade Italian stuff, apparently."

"Are you sure you didn't get scammed?" Dad asks, inspecting the pills.

"Mike swore by them, so I have some trust."

"Even then, you do not need Viagra. You're super virile as is. You plan on staying buried in your Dad's hole all week?"

"I'd love to try, Dad, but they aren't for me."

"Who are they for then?"

The innocent confusion on his face makes me laugh.

"For you, silly!"

It takes a bit to register in Dad's brain, but it does.

"What? You want me to fuck you?" His voice isn't emotional, but I can tell he's not quite sure how to feel about it. After all, our dynamic has been set in stone for years now.

"I thought you'd like getting back in the saddle for once. You know I don't like bottoming in general, but with you, I wanna try everything. I wanna feel you inside and out. I'd love it if you would..." I pause to focus his attention, "Breed me, Dad."

His mouth is slightly open, his face entirely still.

"Will you breed me? Show me the seed I came from?"

He lets go of my dick completely and plants his lips on my neck, pulling at my skin with newfound passion, like he's tasting me for the first time.

"I'd love nothing more, Son."

*****

An hour of rest and a midnight snack later, we're back in bed. Both of us are tense despite pretending otherwise. The Viagra kicks in on time, with Dad's cock swinging around at full mast, threatening to shoot any innocent bystander. It might not be long, but it's got good girth and a slight curve upwards. I examine him from the bed where I lie on my stomach, already excited at the thought of having it inside me.

"So..." I start, "how's it gonna be, birthday boy? Doggy? Missionary? Or do you want me to ride you till the sun comes up?"

Dad mulls it over while he gives his penis a few tugs for relief.

"Do you mind if we do it from behind, Pete?"

That was shy Dad, the one hesitant at new things, but indulging his son out of love.

I was gonna break that Dad thoroughly today.
"Of course not, Dad. It's your birthday. I can do splits on your dick if you'd ask!"

"Well, I'm not going to." Then he adds under his breath, "yet."

I smile and try to relax into the bed, face down and ass up, my defined muscles not used to this kind of position, but providing ample bait to wake up the sleeping beast. Dad gets behind me, and I feel his body hair tickle my ass and taint as he carefully lines up his cock with my hole.

"You sure you don't want any warm-up, sport?" He asks again.

"I told you I already prepped, Dad. My hole is ready and waiting!"

He pats my shoulder reassuringly, then pushes the head against my rosebud. The bed creaks, and I feel his body weight shift as it starts relaxing onto me. I moan quietly into the pillow and try to push out, try to accommodate my Dad's dick as well as possible. I push back in excitement, but end up causing his dick to slip off.

"Easy, tiger!" He reassures me, his worker's hands firmly grasping my hips.

He pushes me down, making me arch harder. Guiding his cock properly this time, he gives a slow, deliberate thrust, and the head pops past the ring. I groan harder, the sensation in my hole alien but welcome, made better with Dad's precise moves. Guess you don't get to be a great bottom without knowing how to dish it out yourself.

Dad lowers his face, kissing my ear and pulling it back as he cores out my unused hole, stretching the tissues and resizing his son with his dad dick. It's not even fully in before the foreign sensation melts into delicious fullness, and my body pushes out on its own, happy to have its maker claim it once more.

I buck my hips back when the itch in my ass grows too demanding, yelling out at the intrusion to my back door, and Dad freezes instantly.

"You good, Pete?"

"Dad, if you don't start moving your hog inside me, I'm gonna flip us over and ride you till there's not a drop of liquid left in your body." I shove my ass back again to prove my point.

"Got it, Son," he chuckles, "Dad'll take care of you."

He sinks in with one long, strong push until his furry belly rests comfortably on my ass, and his big balls slap against mine, warm with his own baby batter. The curve of his cock drags right across my spot, and my eyes roll back.

"Fuckkkk... that's it." I hiss

Dad exhales, slightly off balance, like my hole is drawing out his life force. "Jesus Christ. Your hole is tighter than anything I ever felt, Son!"

He gives us a second to breathe, then pulls back slow, almost all the way out, before sliding home again. The drag is, once again, perfect. My toes curl against the sheets.

"Dad... Please... Again..." I basically beg at this point. It's like having the world's most frustrating itch and finally getting it scratched.

He starts fucking me steadily, finding a pace so as not to blow his load right away and also keep driving me towards the edge. He fucks with deep, loving strokes, each thrust making the bed groan with us and causing my own dick to leak onto the bed, making the circle of precum bigger and darker. Dad leans onto me further, fully placing his weight on me this time. The feeling of his flesh covering mine entirely sends a spasm through my body.

"Your hole is so fucking perfect, Pete!" He says through grunts, the new, warm physical stimulation doing its work on him.

"Happy birthday, Dad!" I say as he locks my head between his two hands, "I'm all yours, whenever you want. Soul, dick, and hole!"

This sets the fire in him ablaze, sending him into a mean fuck frenzy.  His crotch rams into me over and over, trying to break something inside, and I start moaning into the sheets, any feelings other than being my Dad's bottom, his precious biological cumdump, disappear from my head. One of his big hands slides under me, tickling the head of my cock before holding it with an iron fist. The sensation is so good, I nearly, actually sob.

"Is this what your gift for me, Son? Letting me get balls-deep in the ass I helped raise?" He basically shouts the words.

"AAAaaa- Yes- YES. Fuck me, Dad. Breed my ass!"

Looking back from the receiving end, I see a version of Dad I haven't seen in a long time. The focused look, the lip bite, the sweat dripping down onto my back, basking me in his essence. It's the same man I fell in love with nine years ago, before taking his cherry, before dumping a load in him every day became an everyday activity to me. I can tell he feels it too, the intensity in his eyes betraying the myriad of emotions currently bubbling up inside him. Fear of getting left behind? Jealousy at a fictional competition? Joy at the flesh milking him like a young buck? They're too many and too complex to process, instead getting funneled into his fucking, putting all his pent-up emotions into each thrust.

He jacks me at the same rate as his fucking, and I feel the throb of his dick, an unmissable male instinct, as he prepares to load me up with the same cum I came from.

"Fuckkkkkkkk...."

He ruts into me, finally unleashing his hidden, guttaral load into my insides. The warm sensation of getting filled up spreads from my ass to my guts and then all over my body, as if his hot seed is actually fertilizing me. It tips me over, and I yell into his hand, almost biting down on it as I ride my orgasm with him, my cock jerking wildly under me, each touch between him and the bed and my abs causing my body to jerk like a wild horse.

Dad collapses onto me when his high subsides, and I feel my fresh load get squished all over. His weight is comforting, lovely, reminding me I'll never, ever stop being his son. My ass milks his spent dick, its hunger awakened in full force, and he twitches a couple of times, releasing the last of his load. After a minute, it slips out, and I almost whine out loud at the hollow feeling, but settle down as the fluid runs down my ass and mixes with my own mess under.

It's when he flops over onto his back beside me that I roll over, grinning like an idiot at my accomplishment, thoroughly satisfying my Dad. He looks at me, chest heaving rapidly, and sweetly caresses my butt before scooping some of our mess up to taste it. He slobbers all over his semen-covered finger, then smacks his lips and pats my ass.

"Best fucking present," he can only say that before he leans in to kiss me again.

I laugh and roll over him, resting my head in his pecs now.

"Round two?" I ask, my dick already hurting as it tries to rise once more.

Dad laughs out loud, feeling lighter than ever, and gives me a bear hug.

"Give me an hour, tiger. I'm still fifty, you know, gotta pace myself."

To my own amazement, I can see that it's not an excuse. The man looks at me with intent, already anticipating his second load. I nuzzle into his neck, breathing his scent and stroking the new flame with my body.

"Take all the time you need, birthday boy." I say, holding his hand in mine, "I'm not going anywhere."
