It has been three days since I awoke to find my nine year old son stuck on my knot. That was one hell of an emotional roller coaster, but in the end we decided I would show Scout the ropes and we would continue to play together. That said, it’s been a chore keeping him off of my dick until the weekend, when we can be sure we will have enough time to really enjoy ourselves properly. Now that Saturday is finally here, it's time to have some fun with my Son! "Scout! Time for breakfast!" I shout up the stairs, after plating a light breakfast for us.

[color=forestgreen] [b]"Coming Papa!" I quickly race down the stairs in nothing but my undies. Ever since Papa and I played, we'd been more comfortable not wearing as much clothing around the house. Seeing Papa in nothing but his undies has been making it really hard to be patient![/b]  [/color]

I catch myself staring at Scout's crotch outlined in his tight, white undies. [i]They are looking a bit worn out, I wonder if I should get him a few new pairs? Perhaps something that will frame that perky little butt of his?[/i] "Are you excited for our plans for today?" I ask before digging in to my eggs and bacon.

[color=forestgreen] [b]My tail wags enthusiastically as I sit down at the table for breakfast. "I've been waiting all week fer today Papa! You said we'd finally get to play today!"[/b]  [/color]

"Hehe, are you really old enough to be thinking with nothing but your dick?" I ask exasperatedly. "Yes, today's the day we get to play, but you also have some learning to do!"

[color=forestgreen] [b]"But it's Saturday!" I whine,[i]I hate doing homework over the weekend[/i].[/b]  [/color]

"Everything in balance, Little One. Lesson One: Patience and Preparation. If you want to play without a mess, you've got to plan what and when you eat ahead of time, as well as clean up before you play. We just ate, so we've got to let our stomachs settle and take some time to clean up afterwards. Why don't you go put on some cartoons and we can cuddle for a bit?"

[color=forestgreen] [b]I'm confused by what Papa means, but I trust him. Trying my best to be patient, I nod and head to the living room to turn on my morning shows and cartoons. I usually watch them with Papa, but we hadn't cuddled much since I turned seven.[/b]  [/color]

I quickly scrub the dishes and join Scout on the couch, pulling him into my lap and laying back with him cuddled against me. "Power Rangers, huh? I thought we were gonna watch cartoons."

[color=forestgreen] [b]"They’re so cool though Papa! It's my favorite show! You know that." I huff a little, folding my arms at Papa forgetting my favorite show of all time![/b]  [/color]

"Yeah, I know." I tell him as I cuddle him in close, enjoying his soft, warm fluff against my own soft belly fur.

[color=forestgreen] [b]I lean back and feel immediately comforted by Papa's fur. It feels like a big, warm pillow and makes watching the show a million times better![/b]  [/color]

We spend the morning cuddling and watching tv until it's time for us to clean up in preparation for funtime later. I went shopping the other day and purchased some new equipment for the bathroom, which I awkwardly spend a half hour teaching Scout how to use.

[color=forestgreen] [b]"Do I gotta do that cleaning every time I wanna play Papa?" I ask while I dry my fur. "And do we gotta do it together?" [i]It felt weird doing that in front of Papa.[/i][/b]  [/color]

"Nah, you only really have to do that when you're gonna be doing what you did when you woke me up the other night" I ruffle his head teasingly, "And I'm sure you'll get the hang of it the more you do, so you shouldn’t need me to help next time."

[color=forestgreen] [b]"You mean cleaning out for when it goes in my butt?"[/b]  [/color]

"Yup, gotta clean up to prevent a mess! And speaking of cleaning up, why don't you run along to my bedroom while I clean this stuff up real quick?"

[color=forestgreen] [b]"Okay Papa, I'll meet you there!" I run off down the hall to Papa's room, which is much bigger than mine. Papa’s dirty clothes are piled up in the left corner ‘cus he never got himself a hamper like he did for me. Next to the clothes is his dresser and mirror. To the right is the door to the walk in closet, where I used to hide during games of Hide and Seek when I was smaller. Papa's bed is in the middle on the back wall. It's super big and made for a king, he told me. There are matching bedside nightstands, each with three drawers, on either side of the bed. I flop onto the bed on my tummy since my tail can't stop wagging with excitement. My willy rubs against the soft sheet and I notice it begins to stiffen, sliding out of my sheath at the thoughts of what Papa's going to do with me. I start gently grinding my hips into the mattress, feeling it tingle a bit already.[/b]  [/color]

I quickly sanitize everything and put it away before heading to the bedroom. As I approach, I can hear my little Scout wiggling excitedly on the bed. I turn the corner and see his butt already in the air, tail wagging like there's no tomorrow and just like that my cock starts to make its way out of my sheath, growing quickly as I stare dumbstruck at the tight little hole that can somehow miraculously take all of me. "Excited already, huh?" I say as I walk over, sit down, and squeeze Scout's bubble butt. "There will be plenty of time for you to have your butt in the air, but first come sit next to me while we have The Talk."

[color=forestgreen] [b]I startle a bit as I was caught up humping the bed. Papa's paw on my butt feels good and I love the pressure of the squeeze. As he sits down, I roll over and sit up. "The Talk, Papa? What's that?"[/b]  [/color]

"It's something every father and son have to talk about when the son is old enough to start thinking about playing with others" I say as I put an arm around his shoulder and gesture widely. "I'm supposed to tell you about what sex is and how to be safe about it. That said, this is going to go drastically different from how my own Papa gave me The Talk, and indeed how most every other father gives The Talk. This one is special because it's going to be interactive!" I exclaim as I drop my arm from his shoulder to hug him closer while reaching around to grope his crotch. I notice that what he was doing to my bed a moment ago has already got him worked up, his dick hard and almost half out of his sheath.

[color=forestgreen] [b]I moan as Papa's paw finds my weiner. "It's not usually interactive is it Papa? Is... is that bad? Should we not be doing this?" [i]I know we talked about how others don’t really approve, but I really, really liked playing with Papa![/i][/b]  [/color]

"Hehe," I chuckle wryly. "Most people would say it is, but we both have each other's consent. I'd rather you be safe playing with me than going off on your own and possibly getting hurt or accidentally hurting someone else."

[color=forestgreen] [b]"If you say so Papa." I lean into his side and nuzzle as he continues to play with me. The feeling is really nice and I start to relax, quickly reaching full stiffness. It’s not as impressive as Papa’s, but it sticks out of my sheath rather impressively to me.[/b]  [/color]

I stop fondling his stiffy and turn to face him. "First, the basics. When most people talk about sex, they think in terms of a man interacting with a woman. It doesn't have to be just a man and a woman, so long as all parties consent." [i]Hoo, boy. Even after we've done it this is still an awkward conversation![/i] "Now, when a guy sticks his penis in the woman's vagina and cums, that's nature's way of combining their genes to create a baby. Nine months later you'll have a little one of your own!"

[color=forestgreen] [b]I nod as Papa explains. "Cum is that white stuff that comes out of my penis right? And the vagina is that hole girls have instead of a penis?"[/b]  [/color]

"That is correct! Speaking of which, let's get in to the fun part: the mechanics and how this all works. First you have your penis,” I say as I grope his sheath, eliciting some fun noises from him as his tip starts to peak its way out once more. "This little guy will get bigger the more sexually excited you get. He'll make his way out of your sheath, at which point your knot will start to swell." I give his burgeoning knot a little squeeze for emphasis.

[color=forestgreen] [b]I whimper and shudder as Papa teases me with his paws. Each touch sends waves of pleasure through me. "A knot?" I look down to where Papa squeezes. There is a bit of swelling. "That's the really big thing that made me yelp and then wouldn' let me off of you the other night?"[/b]  [/color]

"Indeed! Its biological purpose is to get stuck and keep all the cum inside to improve the chances of having kids. That said, a penis doesn't have eyes, so it can't tell the difference between a vagina, a tailhole, or a hand." At this point I slide my fingers down to the base of his cock, just below the knot and squeeze, simulating a tie and giving it a little tug.

[color=forestgreen] [b]I whine as Papa squeezes. I try to pull back and find I'm stuck in his grasp. As my knot pulls against his hand, it sends little jolts through my body and up to the tip of my penis. He has to close his fingers really tight as my knot isn't too big and I'd normally be able to easily slide through.[/b]  [/color]

I squeeze his knot, feeling it swell more and more with each twitch and throb as he starts to leak. Once my paw starts to become slick I let him go and rub the tip with my thumb. "This slick stuff is called pre-cum, though most abbreviate it to 'pre'. It shows that you're excited, and it can help lubricate yourself for more fun." I bring my pre-cum-soaked fingers up to Scout's lips. "And some people really enjoy the taste of it."

[color=forestgreen] [b]I squirm and moan as my knot actually gets a little bigger. The tingles get more intense and I can feel myself dripping. When Papa starts rubbing his thumb over my tip, it's the most electric feeling I've ever felt. It's almost overwhelming and my body shakes. As Papa holds the wet stuff up I sniff it. It's similar to the cum, but not as strong. I lean in and start licking it off his fingers. It's not as thick and gooey as cum and it's a little sweeter.[/b]  [/color]

As Scout begins to suckle at my fingers my own cock throbs and I know I'm beginning to leak as well. My cock pulses with need and I decide it’s time to see how well my son knows how to use his mouth. "How about you give Papa's a taste for comparison?"

[color=forestgreen] [b]I look down and notice that Papa's tip is glistening with his own pre and lean down to gently lick the tip. Papa's pre is a little saltier than mine. Licking it off his penis makes me more excited than licking my own off his fingers.[/b]  [/color]

"Oh, that's a good boy Scout! That feels really good, just keep going like that." His lack of experience is countered by his enthusiasm as he just goes to town licking all over my stiff cock. After a few moments my cock throbs, giving Scout more pre to drink down.

[color=forestgreen] [b]Papa's words encourage me and I lean forward to take his tip into my muzzle to lap up the next gush of pre. I eagerly swish it around, enjoying the salty taste before swallowing it down. I come off Papa's cock and look at him with a smile.[/b]  [/color]

I tussle his ears and tell him, "that felt great Little One, and if you lay back I'll show you just how great that felt!"

[color=forestgreen] [b]"You will?!" Papa's words startle me. I didn't know he'd want to play with mine like that! My excitement makes me tremble and my tail starts wagging uncontrollably.[/b]  [/color]

"It's only fair," I say as I gently push him back so that he's laying flat on the bed, his throbbing boyhood fully erect. I run my paw through the silky, soft fur from his chest to his belly, all the way down to his cock and pull his sheath completely down below his knot. I give it a light squeeze before licking from the base of the knot to the leaking tip. I slowly tease a little more pre from him with just my tongue before slowly taking all of him into my mouth, even past his knot. At just over four inches, it’s not long enough to trigger my gag reflex, so I can enjoy the entirety of him in my mouth. I can feel it twitching as I swirl my tongue around the top of his knot to the small fountain of pre at his tip.

[color=forestgreen] [b]Papa's hands rubbing my fur relaxes me. I sink into the bed until his tongue starts working on my weiner. It sends shudders through me and makes my muscles tighten. I nearly howl as he takes my whole shaft into his muzzle! It's so warm and wet! Waves of pleasure radiate all through my tiny body![/b]  [/color]

I spend a few minutes bobbing up and down, sucking on Scout's smaller member and enjoying the cute sounds he makes as he squirms beneath me. With how much he’s squirming and leaking I can tell he’s getting close, so I’ll need to stop or he’ll pop! I once again take all of him in my mouth and suck hard, clamping down with my lips as I slowly come off of him with a loud 'pop'!

[color=forestgreen] [b]Papa's mouth feels incredible as he slides up and down my boyhood! The individual waves become one building sensation. I wiggle and moan, feeling myself getting closer to cumming! When he goes all the way down, I feel like I'm about to, but without the continuous stimulation, it starts to go away. Then he pulls off and it feels like he's trying to yank my willy off my body. I yelp as there is a little pain![/b]  [/color]

"How are you feeling, Little One?"

[color=forestgreen] [b]"Tha’ felt really good Papa! I almost came!"[/b]  [/color]

"Well, it's a good thing I stopped when I did! We've got plenty more to do before we're done!" I flip Scout over and continue with the lesson. "Usually before you put your dick into someone else you want to get them relaxed and ensure their hole is ready. This goes for males and females. It's also one of the reasons you want to clean up before you play!" I begin to gently knead Scout's butt before grabbing the base of his tail and pulling it back to expose his twitching tailhole. Slowly I lick from the back of his balls to the base of his tail, lapping against his entrance.

[color=forestgreen] [b]I’m not expecting Papa to pull my tail up. I thought him seeing my tailhole would be embarrassing, but I find myself throbbing! I let out a long sigh of pleasure as his tongue licks up between my legs and to my hole. I can't believe he’s putting his mouth back there![/b]  [/color]

I continue to lap at his tailhole, making sure it's nice and slick with my saliva before pushing into his warm, tight entrance, enjoying the sensation of him squeezing against my invading tongue.

[color=forestgreen] [b]"Ahh! Papa! Tha's-ahh-so good! Eep!" I can't help but squeeze my tailhole as his tongue gets deeper and deeper. I can't believe he can get his tongue IN me! The jolts of pleasure are vastly different than when he put his dick inside me! It is gentler and more focused.[/b]  [/color]

I bury my muzzle as deep between his cheeks as I can, his tail wagging against my nose and my teeth pressed gently against his pucker so that I can get my tongue as far in as possible. I carry on like this for several minutes, fucking him with my tongue and trying to get it as deep as I can go and getting him as slick as possible with my drool.

[color=forestgreen] [b]"Papa! I think I need somethin’ bigger." Papa's licks are driving me wild! It feels like I need Papa to put more in there. His tongue is amazing and making me so sensitive. I need more though! I need him to hit my spot![/b]  [/color]

Once his tailhole is thoroughly slicked, I come up for air and explain, "Now that I've loosened you up we can get to the fun part. While your balls make cum…" and here I give them a light squeeze.

[color=forestgreen] [b]I yip a little when Papa squeezes my balls. It doesn't hurt
 a lot, but it definitely feels like a lot of pressure builds up and it's a little uncomfortable. But it also makes me throb more?! [/b]  [/color]

 "Your prostate is where it's stored."

[color=forestgreen] [b]"My prostate Papa?"[/b]  [/color]

I slip my finger into his tailhole and wiggle it about in his warm, slick depths until I find the magic button and give it a strong massage. "This right here is your prostate." I give it a few light jabs with my finger. "And it’s also what makes having something in your butt feel soooooo good!"

[color=forestgreen] [b]As he slips his finger in, I moan a little. It doesn't hurt being so slicked up and relaxed from Papa's tongue. When he presses my prostate, I yip as that familiar electrical charge feeling shoots from inside my butt to my throbbing weiner. The constant massage a few moments later has me squirming and groaning and building up to cumming. "Papa!" I say with urgency in my voice as the jabs push me extremely close to squirting.[/b]  [/color]

Seeing Scout about to blow I stop and gently pull my finger out. "Did you enjoy that, Little One?"

[color=forestgreen] [b]I huff and shudder as Papa's finger leaves me. "Uh huh! Tha' was amazin' Papa!"[/b]  [/color]

"Trust me, it's about to get better! The next thing to learn is more important for when guys have sex: lube!" I say as I pull out the small bottle from my nightstand with a flourish "This stuff makes it easier to put your willy in a butt without hurting your bottom. There are a bunch of different types and your personal preference will vary. You just need to remember two things: oil-based will melt condoms and silicone-based will melt most dildos."

[color=forestgreen] [b]I watch as Papa pulls out the lube. "That's what makes it slippery right?"[/b]  [/color]

"Correct!" I roll Scout over and have him sit up. "Give me your paw" I say before squirting a glob of lube into his outstretched paw. "Now rub that stuff all over our dicks."

[color=forestgreen] [b]I flex my paw, feeling the wetness spread across it. "Dicks Papa?"[/b]  [/color]

"Weiners, Willys, Penis, Cocks, Dongs, Pricks, Peters, Dicks!" I laugh. "So many fun names for them, but my preference is dick. You can keep calling them weiners, though."

[color=forestgreen] [b]"Okay Papa! I understand." I reach down and apply the lube to my weiner first. My paw slips all over it and the stimulation feels really good. I reach over and start stroking Papa's dick with the lubed up paw to spread it around. Papa’s shaft is so much bigger and thicker than mine that I have to move my hand twice as much to cover it in lube. I can barely close my paw around it![/b]  [/color]

The feel of his inexpert paws exploring my cock is magical. His grip is light and his fingers are soft as velvet, just barely able to close around my girth. "You can tighten your grip if you want." I encourage him. "And be sure to get it completely covered!"

[color=forestgreen] [b]I follow Papa's instructions and grip it tighter. Papa's shaft feels really big in my small paw. I briefly question how I actually got it in my butt. I stroke up and down, ensuring every inch is covered with the slick substance.[/b]  [/color]

"Oooh, yeeeaaah, that's it!" I groan out my pleasure, throbbing a bit as my first spurt of pre leaks out to mix with the lube covering my dick and Scout's paws. "That should be good enough, now roll over onto your stomach for me."

[color=forestgreen] [b]I quickly flip back over to my tummy, my tail wagging excitedly as I wait for what I hope comes next. "Are you gonna put your dick in my butt now Papa?!" I say excitedly.[/b]  [/color]

"That's the plan!" I say as I climb up behind him. I pause to take in the sight of my Scout beneath me. His soft, charcoal fur covering his slight form, tail wagging excitedly above his pert buttocks. His back is arched slightly giving me a wonderful view of his tight tailhole, still slick from my work earlier.[i]What did I ever do to deserve a son like this?[/i] I start by grinding my length against his entrance to add some more lubrication. I can hear him whining needily beneath me, so I bring my tip to his hole and begin pushing in slowly. The confines of his tailhole are tight, slippery, and oh so deliciously warm. Luckily my work earlier has loosened him enough that he can handle me easily.

[color=forestgreen] [b]I wiggle as Papa rubs himself against me. I don't know why, but the need to have him in me makes me whine. Suddenly, I feel the pressure of him trying to enter me. With almost no pain I feel him slip in, causing me to groan. This position feels much different than the other night! Papa's tip hits different spots and not the magic button. I feel full, but content.[/b]  [/color]

I slowly push my way in, marveling at how he's able to accommodate my thick cock! The tight warmth of him sends shivers up my spine and as my knot pushes up against his entrance I can't help but throb my pleasure into him.

[color=forestgreen] [b]Papa's dick goes in much easier with the lube! Every inch makes me feel fuller and fuller, sending shivers and tingles all over my little body. I instinctively clench my tailhole as Papa's knot pushes against it. While there hasn't been a lot of pain with the lube, that knot is BIG![/b]  [/color]

I hold myself hilted, but for my knot, in my son's clenching ass. For a few moments I hold there enjoying him clench,, while I throb in response. Then I start to grind against him, getting him used to motion down there. "I'm gonna start thrusting. Are you ready?"

[color=forestgreen] [b]I nod hurriedly. "Yes Papa! The grindin’-ahh- hits my prostate!"[/b]  [/color]

At that I slowly pull out until just the tip is still in him before pushing my way back in, back down to my knot, shuddering in pleasure as he grips me once again. I slowly build a rhythm, being sure to angle myself to hit his prostate.

[color=forestgreen] [b]Papa thrusting in me makes me groan and moan involuntarily. His dick feels amazing sliding in and out of me! My tailhole feels warm as he picks up speed, and each hit of my prostate makes my body spasm.[/b]  [/color]

I feel Scout getting used to the motion and start to pick up speed until I feel the need to fill his butt start to rise. This is the tightest ass I've ever experienced and I want to enjoy it, so I stop and grind into him until the urge to cum goes down. I repeat this several times, jackhammering into his ass and then grinding my knot against his entrance, slowly stretching him further and further.

[color=forestgreen] [b]"Oh Papa! This feels so good! I can feel your knot gettin’ bigger and goin’ back down!" I push myself back against his knot, trying to relax my hole. It takes a bit of concentration, but the stretch doesn't hurt this time.[/b]  [/color]

"Oh no! No knotting this time!" I say breathlessly, trying to hold myself back as long as I can. "We have more to do that we can't have you stuck on me for!" At this I pull out and flip him around so that he is on his back before lining back up and slamming my cock into his depths, hammering his prostate with every solid thrust. "I'm not going to last much longer!"

[color=forestgreen] [b]"Ah-Papa! Ah, wait! Ah! Ohhh!" Papa thrusting into me on my back hits my prostate over and over! My willy flops over my body and the pre leaking from it flings over the two of us! I can feel myself close to cumming![/b]  [/color]

I pull out at his request, a spike of adrenaline rushes down my spine! "Are you ok? I’m not hurting you am I?"

[color=forestgreen] [b]I take a moment to catch my breath. "No hurt Papa. It just felt so much more intense on my back! You were thrustin' like crazy! I thought I was gonna cum!"[/b]  [/color]

I relax, glad that he's ok. "That's ok, Little One, no need to hold back." I slide back in and resume fucking my son, my own orgasm building as I watch him writhe in pleasure beneath me. "Cum if you need to."

[color=forestgreen] [b]I whine and moan as my prostate is pounded mercilessly! The buildup is a lot, but I'm not going over the edge![/b]  [/color]

I feel myself coming closer and closer to the edge and can see that Scout is getting close too. I can't resist his adorable moaning face any more and bend down to lock muzzles with him. I shove my tongue deep into his mouth to tangle with his as I spill over the edge. I moan my orgasm into his mouth as jets of my cum shoot into his ass!

[color=forestgreen] [b]I kiss back as I feel Papa's dick throb and shoot molten cum into me. I swear it feels like liquid fire, but this time there's no pain. Waves of ecstacy flow through me and I can't hold back anymore! The heat and throbbing against my prostate send me over the edge and my willy shoots ropes of cum too! It hits our chins as we continue to kiss.[/b]  [/color]

I shudder as my orgasm fades and I throb the last of my cum into Scout's ass. Breaking the kiss, I lean back to see him blissed out from his own orgasm. I pull out of his tailhole and watch as my cum leaks out, his hole clenching to keep it all from spilling out.

[color=forestgreen] [b]I feel extremely empty without Papa's dick in my tailhole and whine a little at the feeling. I take a few deep breaths to relax as my orgasm fades. "You dun' have ta knot me ta cum Papa?"[/b]  [/color]

"You didn't have to knot me to cum either." I say, sticking my tongue out at him teasingly.

[color=forestgreen] [b]"Yeah, but I wasn' in you... I couldn' knot."[/b]  [/color]

"And I didn't want to get stuck in you like last time. After we rest up for a few it will be your turn to show me what you learned." I explained exhaustedly before I  collapse next to Scout and cuddle him while I catch my breath.

[color=forestgreen] [b]"Wait what?!" I look at Papa confused. Does he mean what I think he means? Am I going to put my willy in his butt?![/b]  [/color]

"You heard me, I want you to show me what you've learned! You're young, so your refractory period should be low."

[color=forestgreen] [b]"Refractory period?"[/b]  [/color]

"It's how long before you're ready to cum again. Your Papa's is pretty low compared to other guys my age, but yours should be even lower. Hell, I bet you're already ready to go for round two!"

[color=forestgreen] [b]Sure enough, my willy is already starting to get hard again. "I got it Papa. Is that why I'm gettin’ stiff again?"[/b]  [/color]

"Indeed!" I roll over onto my stomach and lift my tail out of the way for him. "Why don't you get started on prepping me while I recover myself?"

[color=forestgreen] [b]"Okay Papa." I stare at Papa's twitching tailhole and get a rush of excitement. It feels weird knowing what a butt usually does, but Papa licked mine and I know he cleaned his. I lean in and sniff, surprised that it smells really good. A little musky, but not bad. I gently lower my muzzle to his hole and stick my tongue out to lick it. Like his dick, it's a little salty from the sweat, but otherwise there isn't much taste. It feels smooth on my tongue.[/b]  [/color]

"Ooh, that's it Little One, no need to hold back."

[color=forestgreen] [b]I dig my tongue in at Papa's encouragement. I feel his hole clamp around my tongue as I try to push it in. I swirl it around the outside a little, trying to make sure to spread out the feeling.[/b]  [/color]

The slick sensation against my tailhole sends shivers racing up my spine and I clench against the intruder involuntarily. I try to relax and enjoy having my son lapping at my rear, while my cock starts to harden once more.

[color=forestgreen] [b]"My jaw is gettin’ a little tired." I say, pulling back and rubbing my paws over Papa's round butt. My weiner leaks a little and throbs as I massage his cheeks.[/b]  [/color]

"If your jaw is tired, grab some lube and use your fingers." I'm a bit disappointed that he can't last long with his tongue, but we can work on that later. "Feel around in there and see if you can find my prostate."

[color=forestgreen] [b]I grab the lube and slick my fingers up. I carefully push my right index finger into the tight hole. It's surprisingly warm and wet and I can feel my weiner leaking even more. I feel around, trying to locate the prostate. "What am I feelin’ for Papa?"[/b]  [/color]

I moan a little as his finger stretches my hole. "Towards my front, a few inches in you should feel a large bump."

[color=forestgreen] [b]I feel around with my finger and locate the bump. I gently rub it with my finger, curious to see how Papa reacts.[/b]  [/color]

When Scout finds that spot an electric jolt shoots through to the tip of my dick and I can't keep my ass from clenching around his finger. "That's my boy, right there!"

[color=forestgreen] [b]"Your tailhole tightened a lot Papa!" I rub the spot more, giggling a little at Papa's noises.[/b]  [/color]

I moan as waves of pleasure flow through me. My cock is fully erect and throbbing while my ass is clenching as he plays with my prostate. "Woah, yeah! Not too much Scout! You're supposed to be loosening me up and I can't relax if you play with it too much!"

[color=forestgreen] [b]"Oh, sorry Papa." I stop massaging his prostate and proceed to slowly add a second finger to Papa's butt to stretch him. It wants to resist, but I can feel it open up to fit the second finger. [/b]  [/color]

With the pressure on my prostate gone I can breathe and relax into the stretch of my son's fingers. "That's it Little One, slow and steady wins the race."

[color=forestgreen] [b]"Your butt feels really warm on my fingers Papa." I rub against the prostate a few times, but don't go over and over.[/b]  [/color]

"Good grief, you're really good at this!" I moan out. "That said, I think it's time to show me what you can do!"

[color=forestgreen] [b]"You mean with my weiner?" My tail starts wagging fast.[/b]  [/color]

"Fuck me!" I moan needily.

[color=forestgreen] [b]I eagerly climb onto Papa and position myself so that my willy lines up with his tailhole. I'm nowhere near as big as he is yet, but I manage to find it with my tip. I push a little and am surprised at how easily I slide in with all the lube! I sink all the way in and moan as Papa's tailhole surrounds my weiner in blissful warmth. It's an incredible feeling and I can't help but start moving!

It feels like I'm being split in half as Scout hilts himself in the first push, fledgling knot and all! "Woah, hold on!" I call out before grabbing his hips behind me to hold him in place. "Slow down and let me get used to you! You aren't THAT little!"

[color=forestgreen] [b]"S-sorry Papa.” I say sheepishly. “It jus’ feels so good!"[/b]  [/color]

"I know son," I say as I clench down hard on his slowly forming knot, "just go slow at first. You can pull out a bit now."

[color=forestgreen] [b]I pull out a little, relishing in the feeling of Papa's tailhole around me.[/b]  [/color]

The intense fullness abates as his knot pops out of my tailhole. "That's it Son, take your time and enjoy it."

[color=forestgreen] [b]"Oh Papa. It's so good!" I gently push into Papa again.[/b]  [/color]

As Scout begins to build his rhythm I start to push back to meet him, immersed in the filling sensation of his cock pumping in and out of my ass.

[color=forestgreen] [b]I moan as my willy throbs inside Papa's tailhole. I can feel myself building to cumming rather quickly![/b]  [/color]

I hear his adorable moaning and warn him, "If you think you're about to cum, pull out for a minute so that you can come down and last longer." The feel of his throbbing boyhood prodding my prostate is wonderful and I want it to last as long as it can!

[color=forestgreen] [b]I immediately pull out as I was right on the edge! I let my willy throb over Papa's tailhole. "Why can't I cum Papa?"[/b]  [/color]

"You can, just not yet." I tease him. "You want the fun to last, don't you? How big is your knot, is it still growing?"

[color=forestgreen] [b]I look down at my swollen knot. I see it grow a little before going back down. "It's shrinkin’ Papa."[/b]  [/color]

"That's good, just remember that it won't shrink so quickly when you've knotted me."

[color=forestgreen] [b]"Should I not put it all in you Papa?"[/b]  [/color]

"For the time being you should be small enough to knot fuck me without fully tying me just yet." I lift my ass and wag my tail, brushing his face with it. "You should give it a try!"

[color=forestgreen] [b]"I should?" I’m a little confused by Papa’s request.[/b]  [/color]

I should be loose enough by now, and this is one of the few chances I’ll ever get to be truly knot-fucked, so I want to give it a try. "It will be amazing! For the both of us, I'm sure!"

[color=forestgreen] [b]I push my willy back into Papa's butt and moan. My knot almost immediately begins to swell at the sensation! I push it against Papa's tailhole and it pops in without too much resistance. The feeling sends more pleasure than imaginable through my body! As if a switch flips, the only thing on my mind now is thrusting into this warm tailhole until I cum! I speed up, my knot popping in and out as it continues to grow.[/b]  [/color]

It doesn’t take long for my boy to give up control and begin full-on rutting me. With every thrust I can feel his knot pop past my entrance, growing larger and larger each time. The sensation is almost overwhelming and I can't help but to grab onto my dick beneath me and start rapidly stroking myself, my own orgasm building quickly!

[color=forestgreen] [b]"I'm gonna cum Papa! It's so good, I can't stop!" My knot swells bigger and bigger. I can feel the increasing resistance against Papa's tailhole, as with each thrust it gets harder and harder to pull out again.[/b]  [/color]

"I'm getting close too, Little One! Don't stop! Cum for me!" To help him finish in true canine fashion I clench down as hard as I can when his knot pops in once more, trapping it in my ass and tying me.

[color=forestgreen] [b]I can't hold back as Papa squeezes! I feel my knot get stuck and can only move slightly, but it doesn't matter. I've toppled over the edge and there is no holding it back! I howl out and ropes of cum shoot from my willy into Papa. The feeling is overwhelming and natural. This is what I was meant to do![/b]  [/color]

I can feel him filling my ass with his warm, thick seed, and it is wonderful! He clings to me as he shudders through his orgasm, his cock throbbing and spurting within me. I wish this moment could last forever, and I clench down as hard as I can, which also puts just enough pressure in just the right spot to send me over my own edge, to cum into my paw beneath me.

[color=forestgreen] [b]I feel Papa's hole clamp down around my knot, causing me to spurt even more cum! I’m not thinking, completely overtaken by the primal pleasure of filling a hole with my cum! My balls ache as they force every bit of cum out! My body spasms and twitches and, eventually, the feeling starts to subside and I come to my senses. “P-Papa?” I ask a little dazed.[/b]  [/color]

“That’s my boy!” After my orgasm passes I relax enough for Scout to pull out. His knot has swollen enough that we actually have to work to pull it out, causing him to spurt even more as he slips from my tailhole. “You did really good Son.” I say before I exhaustedly roll over and pull my equally exhausted son into my arms and we cuddle ourselves to sleep. I dream of the fun times ahead of us.
