I never thought for a second that Dad might feel the same way about me that I feel about him, until I noticed something strange. See, at first I just thought I was being a ditz, or that in my rush to come home from college I had left more behind than I’d realized. But, no. My briefs really were going missing.

One pair a week on the dot. Two months of summer had gone by and by now I was running low on them. Last night I was hurrying out to meet some friends for a movie, but after showering I scoured my room for a clean pair of undies to no avail. Everything I had was either in the wash-box or missing. I was starting to believe in some kind of extra-dimensional being that steals undies. I mean, everyone already knows there’s one that steals one half of every pair of socks so why shouldn’t there be one for briefs?

Anyway, it was either go commando or come up with workaround, and while commando was tempting, I didn’t like the idea at chafing my tip just because it unsheathed itself mid-film when a hot topless canid comes out in a sweaty action scene or something.

Especially if the guy had a classic dad-bod: that fluffy beer belly, the thick thighs, strong arms, knowing smile and slight scruff that I just can’t resist! Woof! Just the thought of it had me wagging like when I was a pup. It had me picturing my own Dad in one of those trashy action movies with a million dollar smile, shades on, in a fully unbuttoned Hawaiian shirt. In turn, that had me picturing his prestigious bulge, that thick ass and then, heck, what do you know? Once again my tip was poking out of my sheath and leaking. Yeah, commando was a no.

Thoughts of Dad always had me feeling a little guilty too, but I always used to justify it to myself as him simply being ‘my type’. I came out a couple years ago and had a couple flings here and there, but nothing serious. The thing is: guys my age don’t do it for me. I want the maturity and comfort of a dad. Doesn’t have to be my capital ‘D’ Dad, right? At least, that’s what I was telling myself.

Once my dick had retreated into my sheath, I called out for him. Nothing. I called again, louder, poking my head out the door. No answer. He had gone out. Perfect. So, with my sister out of town and Dad doing who knows what, I went out onto the landing in nothing but a t-shirt, sheath and balls on full display. I looked around repeatedly in a display of needless paranoia, but quickly decided that if a thief were in the house, I’d have bigger problems than being naked, so I stuck to my plan and snuck into Dad’s room.

My idea was to steal a pair of his boxers for the night. Yes, they’d be oversized on me, but they’d do for one evening, surely. And, to be honest, if I really have to tell the truth… It was kind of a turn on. The thought of my cock, sheath and balls rubbing up against where his have been so many times… the idea of his sweaty ass having left some scent of him on there. It was almost too much to take! I was getting hard again and didn’t want to leak all over dad’s room, so I dashed past his disheveled bed with barely a glance on my way to pull open his underwear draw.

What I saw inside blew my mind. I was practically licking my lips as I went to grab a pair of his XL (XXL??) boxers, but froze in place when I saw what was neatly tucked in beside them. Not one, not two, but it must’ve been half a dozen of my own, size M briefs squeezed right in beside his own underwear.

Well, not getting intensely horny and leaking all over Dad’s carpet was out of the window. My heart was pounding, my head throbbing, I felt dizzy. I stumbled and fell back onto Dad’s bed. The sudden impact of my butt led to a precariously placed pillow falling off the side of the mattress. On instinct I went to pick it up, but fate had other things in store for me.

There I was, muzzle hanging half open, tongue lolling out of my maw, utterly mesmerized as I saw what Dad had hidden under that pillow. Perhaps my favorite pair of thought-to-be-missing briefs, the ones I bought at pride: pastel blue with rainbow decals all over it. I had bought them just earlier this year, but the last time I saw them they weren’t stained like this…

I snatched them without thinking as my mind went reeling. Had Dad been stealing my briefs? Had he been… sniffing them? Had he… no way, right? He surely hadn’t jerked off and splattered a load of his fatherly juices all over them had he… thinking of me?

My cock was achingly hard, knot bulging in my sheath. I literally couldn’t stop myself from grabbing my rod. Holy heck, I had no idea dad was into boys, let alone… his own son. Fuuuuck. This was no time for edging, everything about this situation was screaming at me to pump my cock, even as I still didn’t believe it, even as it all felt so wrong. I know since he split up with mom he hadn’t brought any women over, but I just thought he enjoyed having his man cave. Never in my wildest dreams could I have pictured this.

I moved as if in a daze, trying to cover my tracks before anything irreversible could happen. I hadn’t had time to think this through. I couldn’t think about anything other than Dad, naked on his bed, whacking his meat, sniffing his son’s butt from a pair of my used underwear and daydreaming of… what? Having me suck his fat cock? Hnng. By then I was in my bedroom, having repaired the scene of the crime, settling back onto my bed and squeezing my sheath with all I had until my knot popped right out.

Or maybe Dad was daydreaming of having me worship his body, his pits, his ass, his taint, his tum, using my muzzle and paws in all the best ways... Rrrruff. I was pumping my red rocket like my life depended on it, barking and panting as if I were actually mid-rut.

Or, what if, just maybe, Dad was picturing pounding his own son’s bubble butt. Fff. What if the thought of thrusting into his boy’s tight ass was what made him- Was what made him… Pop! It was too much. My cock erupted like a damn fire hydrant, the first couple spurts making it all the way to my face with the rest thoroughly ruining my t-shirt and stickying up my paw good and proper. My whole body was on overdrive as I rode out my climax, to the point that I was still pumping my dick, uselessly into the air into the air when I heard the door open downstairs. Dad was back.

“Boy, you still in?”

“Y-yeah. Still here, Dad!”

Leaving horny-land and opening my eyes for the first time since I lay down, I realized my bright blue briefs – the ones tucked under Dad’s pillow – were still firmly clutched in my left paw. I knew then that the moment Dad checked his room he’d know.

Things were about to change between us. A lot of things. I started leaking again.

“Son…”

This was it. The tone of his voice told me everything. I’d managed to clean up and throw on some PJs, utterly abandoning my plans for a night out, since discovering Dad had been stashing away my briefs, buuut not before Dad had already made his way back into his room. There was no way for me to get my briefs back under his pillow at this point, unless he asked for them.

My head was still spinning, I was trying to find some sort of rationalization for Dad’s actions other than him being horny for his own son and, while a couple of ideas came to mind, none of them could push out that assumption.

“Yes, Dad?”

None of that really mattered anyway. By Dad’s tone of voice he had discovered those briefs were missing and we were minutes away from the shape of our relationship changing forever.

I peeked out into the hallway, Dad was standing there, just outside his room, looking at me all sheepishly, head slumped between his shoulders as if embarrassed. I stepped out to join him on the landing. Dad’s unkempt fur, poking out from the bottom of his white tank top where his belly pushed past his belt-line had me re-imaging the scene of him lying there, jerking off to my scent all over again. Even better, his cargo shorts were tight and his prominent bulge had my imagination running wild. But, his ears had drooped, his snout was aimed down and his tail was still.

“You didn’t, uh, didn’t move anything from my room while I was out did you, by any chance?” He asked, struggling to make eye contact.

Make or break time. Whatever I said in the next few minutes could change how Dad and I saw one another for the rest of our lives. I had to be careful.

“Why?” I asked, trying to appear cheerful and teasing. “Anything in there I shouldn’t see?”

“There’s just, uh, something missing that I swore I left on my bed.”

No way. He’s admitting it.

“Oh, what have you lost? Maybe I’ve seen it around.”

I was right! Nobody else planted them there. This isn’t some crazy mind game. No, the way he keeps glancing up at me, as if ashamed, but with the glint of hope… I wasn’t imagining it was I? He totally had the hots for his son. A hundred percent! At least ninety-five. Ninety. Woof! I was off in a daydream again by that point. Practically drooling.

“Uh… Son?”

I looked up. Dad was pointing at my pajama pants. I looked down. I was pitching a prodigious tent down there. My cheeks flushed hot, I covered myself up with both paws and crossed my legs.

“Oh heck. Sorry, sorry!”

Dad let out a big old belly laugh, his deep voice rattling the floor.

“Nothing to apologize for. We’re both guys here, right? Getting a stiff one just happens sometimes right? See something hot at eight in the morning, then suddenly it pops back into your head at eight o’-clock at night!”

“Y-yeah. It’s just like that.”

“You’re still wagging boy.”

I didn’t think it was possible to blush harder than I already was doing, but he managed to prove me wrong.

“D-dad…”

“Must’ve been something real exciting if it got you ike this. Go on, share it with your old man, why not?”

By then he’d walked up to me and given me the classic coach butt-pat. That did nothing to calm my raging erection.

“Wh-what are you talking about? We’ve never shared… stuff like that before!”

“Psshh. Of course not, but you’re a grown man now, it’s time I treat you like one! Come on,” he said, heading downstairs and beckoning me.

Still covering my persistent boner, I did what he said, following him into the living room as he closed the curtains and settled down on the couch, patting the spot next to him. I could barely believe what was happening, and honestly still wasn’t quite sure what I was getting myself into, but I counted my blessings that this incident seemed to make dad forget all about the missing briefs. Maybe after this I’d be able to sneak back into his room and replace them before anything went too far. Not that I entirely disliked the idea of him finding out… Huff.

“Park your butt here and stop being such a pansy about that boner, son. We all get ‘em!”

Dad! That’s so embarrassing!”

“Oh hush, I made you with my own wang, so seeing a hard one through some PJs isn’t gonna shock me, now sit here!”

I did as he said, sitting beside him and, with great effort and very hot cheeks I let go of my tent. With it on full display, the extent of my arousal was more obvious than ever: I’d leaked plenty of pre and left a large, sticky dark patch on my PJs, emanating from the tip of my still-covered, throbbing cock.

Dad let out fine-tuned whistle.

“Hoo-boy! Something really got you going today, huh?”

I screwed my eyes shut while nodding, feeling more humiliated than I’d ever been. Dad patted my thigh and I swear a fresh spurt of pre almost seeped clean through my pajama pants.

“Come on then, son. What’s got you so hot and bothered? You’ve got your old man intrigued. I wouldn’t mind a little show and tell, or if it’s too private to show you can still spill the beans.”

If my cock could’ve got any harder, it would’ve. Thankfully, this time I had an excuse, I could finally de-escalate the situation.

“Dad, you know I’m gay, right?” I tried my best to offer a chuckle but probably ended up sounding more like a half-strangled cat. “It’ll just gross you out.”

He cleared his throat. When I looked at him, he just winked at me. From so close I could smell the musk of his sweat from a long day’s work. It was intoxicating.

“Your old man likes all kinds, actually.”

It was all I could do to let out a shuddering sigh and forcefully keep my paws away from my trapped cock. I wanted nothing more than to rip off my pajama pants and pump another load out right there and then, but I knew that would be nothing short of insane.

That is, until my eyes wandered and I saw how tight Dad’s cargoes were getting.

“D-dad?”

He lifted his paws to the sky and let out another room-shaking belly laugh.

“You got me. I’ve been having that kind of day too.”

Before I could even process what he said, he had stood up, unbuttoned his cargoes, slid them down to his ankles and plonked his ass back down beside me.

There was nothing I could do but stare at the enormous tent, no, gazebo, that had formed in his boxers, and the matching, far-spreading patch of pre my own Dad’s fat cock had produced. I gulped and desperately, desperately, gripped onto the sofa, knowing each of my paws were gonna grab one of our cocks or the other if I didn’t keep them occupied.

“See, son? Nothing weird about a boner.”

“D-dad… wow. You’re big!”

“Tell me something I don’t know,” he said, patting his belly and laughing.

“I, uh, wasn’t talking about your tummy.”

He smirked at me and wiggled his eyebrows. God, it was already borderline impossible keeping my paws off my dick, I didn’t need Dad making innuendos too. It’s already crazy enough that he’d convinced me to sit right next to him when I was already tenting my pajama pants, but since he got his shorts around his ankles and started showing off his own damn gazebo it had become more than I could take.

“So, now that we’re on an even playing field,” he said. “You gonna show me what got you all hot and bothered in the first place?”

Considering that it was discovering my own briefs under Dad’s pillow (and subsequently fantasizing about having sex with him) which got me so horny… nope. That was out of the question. Not that the current situation was dulling those fantasies of mine. In fact, with his boxers exposed and his pre soaking through them, sex with dad was just about all I could think about. Not to mention the heavy musk of his sweaty balls and throbbing cock playing tantalizingly in my nostrils. All I wanted to do was bury my nose in his pubes and deepthroat his fat cock and- oh. Oh gosh.

The good news was, I had figured out an excuse.

“What about you? You’re every bit as hard and leaky as I am. Why don’t you give a show and tell, Dad, this was your idea in the first place after all!”

“Hmm.” He rubbed his chin as if I’d posed him some deep philosophical argument and he sunk back into the couch, causing a little more of his belly to leak out from the bottom of his tank top as it rode up his stomach. My cock throbbed. I was struggling so hard to be normal about this…

“Alright son, I suppose it’s only fair. Since this is our first time jerking it together, I-”

“Wait, what!” My eyes went so wide I’m surprised they didn’t pop out of my head like an old-school cartoon. “What do you mean, jerking it together?”

He let out another of his signature, earth shaking belly laughs.

“What, did you think we were just going to compare tents? Guys jerk off together all the time, it’s a classic bonding experience! Since you’re a grown man yourself now, I thought we should give it a go. Been a while since we had some good bonding anyway. As soon as you hit your teen years you were over hanging with dad. Playing with toys was beneath you and being seen in public with me was an embarrassment! I reckon now that you’re grown enough, we should get back to some father-son time.” He guffaws, and paws absently at the stark outline of his thick cock through his boxers.

I sat there stunned, muzzle half open, just stammering.

“Come on,” he said. “Don’t tell me you’ve never stuck on a porno with some buddies and had a good stroke.”

“W-well, there was one time, with Chester… but that’s about it!”

“Oof, rotten luck. You’re in all the wrong friend groups it seems, son.”

“Daaad!” The worst part is… I pretty much agreed with him. There were always stories floating around about groups of dudes who’d meet up to stare at porn and beat their meat, and I had always wished I’d been at it with them. Not to watch the, almost certainly, straight porn they’d be watching, but to get a sneak peak at all those cocks… Plenty of jerk-off material.

“Well, let’s go ahead and make up for lost time!”

“But, Dad… with you? Wouldn’t that be, I don’t know, kinda weird?”

“Nothing weird about the canine body, son. We’ve both got cocks, don’t we? We both jerk off, right? So why not do it together?”

I couldn’t think of a single sensible argument to refute him. Though, maybe that was because all I could think about was how insanely hot Dad was or how badly I wanted to see him naked, but that’s beside the point.

“Alright.” I said. “I, uh, guess we can try it.”

“Good,” dad said, letting out a long sigh as he grabbed the outline of his thick cock through the fabric of his undies. “Gonna need to relieve this thing sooner than later!”

I couldn’t help myself any longer: I copied him, holding my own dick through my pajama pants and stroking myself through the material.

“I, uh, feel the same way.”

“Attaboy!” Dad chuckled. “But where was I?” He shifted both of his paws so that his thumbs were hooked into the waist of his boxers. “That’s right, telling you what got me so hot and bothered in the first place.”

I was burning up all over in the heat of my attraction and anticipation. Was this it? Was he going to admit he was into me? Was this all a big ploy to break the news?

“Go on,” I said, all breathy as I continued touching up my trapped rod.

“Well, you see. I’ve got this kink for sniffing underwear…”

Fuuuck. “Yeah?”

“And I’ve been daydreaming all day about getting my muzzle all up in a pair of a hot dog’s briefs…” He tugs his boxers partway down to reveal a wild, thick tuft of darker, longer pubic fur, just stopping short of his shaft.

I stopped touching my dick, instead copying Dad and lowering my pajama pants to about the same position, showing off the much neater, short-cropped pubic fur of my own.

“L-like, one particular dog, or…?”

Dad clears his throat and grins.

“Yeah. It’s funny actually, I was looking forward all day to coming home and pushing my nose into his briefs while I jerked off, but when I looked for them in my room, I couldn’t find them. That’s what I was asking you about earlier… I was wondering if you’d seen them.”

My cheeks were burning up, my cock was threatening to burst straight through my PJs.

“Yeah?”

“So… did you see them?” He tugged his boxers down until I could see his swollen sheath, but not the meat that was projecting from it.

“I-I… Yeah, dad… I saw them.” By that point I was more squeaking than talking.

I looked up into his eyes to find him staring down into mine, grinning wide. I could feel my heart pounding hard and blood rushing in my ears, I had to focus hard to hear what he said next.

“Did you like what you saw?”

All I could do was nod.

“Good boy. Very good boy.” He stood up all of a sudden, then dropped his boxers to his ankles.

I pulled down my pajama pants and tossed aside my shirt almost instantly in some primal, instinctual reaction, licking my lips and whining, looking up to his eyes then down to his thick, fat, red rod. He just nodded.

He was so thick I couldn’t close my paw around him, and despite much of his sheath being lost in the mound of pubes and a bit of dad-fat, his length protruded markedly over seven inches out into the open air. What’s more, he was dripping. Even as I watched, kneeling before him, his cock throbbed and an errant spurt of pre splashed against the side of my muzzle. I licked it off without even thinking, tasting Dad’s sex for the first time in my life.

Not the last.

The whole night had been building up to this. Here I was, butt naked, struggling to hold my father’s fat cock in one paw, licking his pre off of my muzzle and looking up to him for instructions, or permission.

“You like that son? Touching Dad’s dick?”

I nodded enthusiastically.

“I want to hear you say it,” he said, grinding forward just enough to touch his tip to my nose and leave behind a sticky spot that I immediately slurped up.

“I love it. You’re so hot, Dad.”

“Beer belly doesn’t put you off?” He asked. I couldn’t tell how serious he was but I shook my head with as much fervor as I can muster to prove him wrong. He chuckled, then pulled off his tank top. “I had a sneaking suspicion you were into it.”

My free paw automatically moved to grab, caress and squeeze Dad’s round, soft belly. He placed a great big paw on my head and let out a hum of satisfaction as he ground his cock along the side of my muzzle.

“H-how did you know I was into you, Dad?”

“Are you kidding? I can practically hear your leaking erection from here.”

He pulled back a little to line up his tip with my mouth. I couldn’t take my eyes off his cock, it was all I wanted.

“Come on,” he said. “Your briefs were missing from under my pillow, and you came out of your room rock hard. Chances were high. Thought it was at least worth shooting my shot.”

My tongue darted out to lap up an errant drop of pre beading on Dad’s cock. He let out a grunt and thrust along the side of my muzzle again.

“Y-you don’t think this is going too far? Doing something like this with your own son?” Even as I asked the question my paws were exploring his body: cupping his balls, grabbing his ass, stroking his belly.

“Nothing wrong with two horny adults helping relieve one other, right?”

I nodded, still keeping my gaze locked onto his crotch.

“Especially if it’s f-father son bonding time, right?” I ask, heart pounding, tail wagging.

“There’s a good boy.” He pet the top of my head. His cock noticeably throbbed at my words, spurting more pre, this time into my waiting, open maw.

Fuck. I was tasting Dad, his salty pre on my tongue tasted like a promise of things to come and I was getting impatient.

“Dad? Can I suck you off?”

“Thought you’d never ask,” he said, grabbing the back of my head and pressing his tip to my lips until I opened up my muzzle and let him slip inside.

God, he was thick. It ached a little even to open up around him—and it didn’t get any easier as he got deeper—but he stopped before hilting, going gentle on me, maybe. Fuck that.

A primal lust took over me and my tongue wrapped around Dad’s cock, lathering him in his own boy’s saliva as I tasted every inch of him I had access to, but it wasn’t enough. I grabbed his hips and shoved my face forward, skewering my muzzle on his cock until my nose was buried deep in his pubic fur and my lips were practically kissing his knot-swollen sheath.

His tip was poking the back of my throat, and it took effort to keep his entire, fat cock in my muzzle, but it was more than worth it. Getting a nose full of his musk sent me straight to heaven. I couldn’t help grinding my nose even deeper into the soft pad above his dick, humming, muzzle vibrating around Dad’s cock even as I licked and suckled it with all I had.

Dad was moaning and grunting loudly, cursing like a sailor.

Fuck, son… we should’ve been doing this long ago.”

That was all the encouragement I needed to snap out of musk-induced stupor and start properly working his shaft. I moved a paw to cup his hefty, sagging balls as I pulled my head away until only the tip of his dick was left in my mouth, then slid my muzzle back and forth over the entirety of his length. I made sure to swallow down every drip of pre as it arrived, delighting in every throb of Dad’s cock, in every time he couldn’t help but grind his hips right up against me, giving me another incredible whiff of his manly musk.

“Can’t get enough of the taste of your old man, huh?” He let out a grunt and thrust so hard that his knot popped free from his sheath and made it’s way halfway to my muzzle.

I didn’t know my muzzle could be this flexible, and now all I wanted was more. I went into a knot-obsessed frenzy, poking my tongue out as much as I could to lap at the thick knot at the end of Dad’s rock solid rod.

“Fuhhh... Flexible fucking cock-lover, aren’t you son?” I moaned in joy at his rhetorical question, tail wagging so fast it was a surprise I didn’t take off. “Mff. How did I get so lucky to be blessed with a dad-sucking gay pup with a talent for deepthroating?”

His voice was quivering along with the rest of him, and I just knew he was close. His legs were turning to jelly, his grip on my head commanding but jittery, his cock pulsing like crazy in my maw. For my part, I was more zealous than ever in pursuit of Dad’s cock, Dad’s knot and Dad’s cum. My very own holy trinity.

I held tight onto his sides and repeatedly slammed my nose into his crotch, begging for his knot to pop wholly into my maw, despite my aching face. This was good training and I knew it. This was what good pups did.

“Fuuck, h-here it comes boy. A-any moment now.” He was hunched over me, barely standing as his whole body succumbed to an intense desire to cum in his son. “Suck down a big load of Dad’s pups, right from the cock that made you.”

With all my might I dragged my muzzle down the full length of his cock, physically forcing his huge, throbbing knot into my maw, tongue immediately fussing over the fattest part of Dad’s fuck-flesh. The effort was worth it. Moment’s later, with a buck of Dad’s hips, his knot securely locked in my muzzle, I was rewarded.

Rope after rope of Dad’s seed splattered against the back of my throat, most of it immediately being swallowed down by his greedy son, with the rest splashing back and filling up my muzzle until I wasn’t sure I could hold any more. Dad let out a bestial groan and ground his sheath to my lips as he pumped his entire, prodigious load directly into his son’s maw. In the end, only a little of it leaked out the side of my mouth, though even that was a great loss.

In the afterglow Dad gently held my head in his paw as he skirted around me, resuming sitting on the couch, with me still attached to his cock by the muzzle.

“Guess you’ll have to wait until my knot goes down, huh?” He chuckled. “Not that I’m complaining. I’m learning a lot of things about you today son. One example being: you make a good cock warmer.”

My furiously wagging tail said all that I needed to say. Dad stroked my head and reclined, letting out a pleasured, satisfied sigh.

I had no idea what would happen next between us, but I vowed then that this couldn’t be the last time I had Dad’s load. I simply wouldn’t be able to live with myself if I never took his knot again.
