Tyler was a wolf on a mission. With his first year of college under his belt, he was ready to step up his pursuit of finding a man who'd let the young boy explore his blooming sexual curiosity.

You'd never know it just by looking at the lithe grey and white wolf, but the persistently upbeat lad had a browser bookmark list full of older men showing boys like him the ropes. A year ago Tyler hadn't even known things like "age play" and "pup play" were a thing but ever since having his eyes opened to this new lust-fueled world he'd spent countless hours masturbating to images and videos of well hung daddy types stretching out wide-eyed kids around his age.

Oftentimes the youths were exaggerating their unease for the benefit of the camera but some of the wolf's favorite movies featured boys who had clearly bitten off more than they could chew. Frequently bound or even gagged, the twinks shocked expression as their mature partner took off their pants couldn't have been faked.

The top would typically spend the next several minutes making sure the much smaller male got a close up look at the thick monster they'd be made to service. There was an elephant dad who was a personal favorite of Tyler's as he always soothed his co-star's nerves with his deep voice, explaining how experienced he was at "opening boy holes".

He'd boop their nose with his massive grey schlong making them smile as he rubbed his shaft all over their muzzle and face. Then he'd encourage the naive teenager to use both hands to get him fully hard, patiently coaching them through their exploration of his equipment. The man would smile as the younger male touched, squeezed, and played with him, his costar treating his dick like an erotic toy.

Next the elephant would have the boy help by spreading copious lube up and down his shaft, holding the youth's hands in his to make sure they felt every inch of erection. The elephant would moan in a slightly exaggerated fashion, flattering the increasingly at ease boy by telling them how great their soft hands felt on his manhood. They'd blush as he told them what good boys they were.

Pulling the kid into his lap so that they were facing him, the large elephant would indulge in some intimate kissing, giving the camera men the opportunity to film a side-by-side size comparison. Modestly proportioned boyhood pressed against beer bottle girth as the camera's viewport zoomed in to frame the one-sided contest. Tyler considered himself reasonably endowed when hard but he had always been far more of a grower than a shower, and a childhood of being teased in the locker room had left its mark. Now it was with guilty pleasure that Tyler raptly watched these other teens get their turn as the elephant broke off the kiss and had them look down, assuring them they had "nothing to be ashamed about" even as he forced them to confront their size difference. The teenagers reacted differently to the man's implied shaming but the elephant never let them talk for too long before he shoved his thick elephant tongue back into their mouths, muffling their words as the well hung dad rubbed his member firmly against their own.

After a bit of mutual stroking, the huge man would convince his on-screen lover to lay back on the durable table, voluntarily strapping themselves into position on the sturdy frame. When the leather straps and accompanying ball gag were in place the older elephant's demeanor subtly shifted as he got down to business. Gone was the warm fatherly figure, replaced by a no-nonsense daddy. The more observant lads picked up on the change and would begin to unconsciously squirm in their too tight bonds, unable to lend voice to their concerns due to the gag they themselves locked into place.

Reaching for the lube, the man would slick a finger before pressing it unceremoniously up the teenager's asshole. The boy's body, fully relaxed just moments before, would begin to tense up as the man buried the greased finger nice and deep. Here many of the youths would try and talk to the man despite their oversized gag, spread limbs flexing in place but unable to move.

The elephant mostly ignored their muffled words, shushing them as his cock twitched in anticipation, the veined fuckpole resting impatiently on the boy's rising and falling chest. Inches away from their face the boys would stare at it, as though suddenly seeing the elongated flesh in a different light than when they'd playfully swung it around. Then they'd been in control, their hand gripping the thick pole at its base as they'd batted it against their tongue and lips. Stuck against the table the boy would grunt in displeasure as the elephant slipped a second finger in between clenched cheeks.

This series of videos always ended the same way. The elephant would pick up an extra camera from under the table and bring it to his face for a close-up. His tusked face grins with a hint of mischievousness as he says, "This is Axel Throb with a new fresh-faced lad. Lubed, stretched, and about to get royally fucked. Purchase the full length video on my website to see just how many inches this kid can take. As always, thanks for tuning in and happy trails to all the tight-holed boys out there."

The man then holds the camera out at arm's length so that the frame captures both the throbbingly erect elephant and uncertain boy as Axel uses his free hand to make the teenager's member wave goodbye to the camera before signing off and concluding the video.

Unable to afford the forty dollar price of admission for each of the full length videos, Tyler never knew for certain what happened next. But his imagination was happy to fill in the gaps as the wolf spent days jerking off to the free to watch 'preview' videos, often circling back to watch and then rewatch the same twenty or so previews starring Axel Throb.

The movies provided potent fuel for the boy's fantasy sex life and the wolf had no difficulty imagining the perfect big-dicked daddy to lead him by the hand. Faintly cologned, the forty-something year old sir would let him explore their body to his heart's content, the gentleman grunting in satisfaction when the college aged kid barely managed to wrap his hand all the way around their hard endowment.

The Axel Throb series was one of Tyler's first exposures to age play but it wasn't long before the wolf's interest was thoroughly captured. Soon after, he found countless websites with endless material on this same kink. All similar but each video or photo set managing to be a little different. Lion dads shaving off their disobedient teen's maturing mane and pubic fur before giving the brat an over-the-lap corrective spanking. At-home tutors mercilessly edging their young pupil's pre-coated member while forcing the panting kid to memorize literary and historical facts. And the ever popular trope of tough-guy coach inviting the school's star athlete to his office for some after practice "hands-on guidance".

This represented only the tip of the iceberg as Tyler discovered when he delved into websites which showed off endless variations of dad types using twinks and teenagers to get their rocks off. In short order the wolf became obsessed with the possibilities, always picturing himself in the place of the eager to please boys depicted in the photos.

The problem was, Tyler wanted more. Fantasy fueled fap sessions were fun and all but why should the bright-eyed, exuberant young men on these websites have all the fun while he was stuck jerking off at home? Though, it wasn't as if the college kid lacked for playmates. Tyler had a few phone numbers of buddies he could text if he just wanted a good time in bed, but the issue was they were all around his age.

He'd tried to get a couple of the older looking jock types to boss him around and maybe call him boy, but it was clear their heart wasn't it. The zebra, and a couple weeks later the polar bear, had just wanted to get their nut and then get on with their day. But even had they thrown themselves into the role, they still looked and sounded too immature to give Tyler what he craved.

All that changed when a website advertisement pointed the wolf towards a new phone app, Boys4Dads. Created in the same vein as popular dating and hook-up applications, the app allowed you to select your category, boy or dad, and then tag your interests. Even better, the wolf found that the app catered to younger men, giving "boys" the option of hiding their profile was still browsing for possible matches.

"Dads" didn't have this choice, their profiles always indexed and searchable. In the "about" section of the app, the developers stated their reasons for this design decision. Recently active Dads outnumbered recently active boys by a large margin and the developers didn't want aggressive alpha types scaring off skittish, sexually inexperienced youths. This format also encouraged Dads to provide high quality pictures and description text in their profile. If a boy wasn't sure what the Dad was into or what kind of experience they were offering, the profile owner could expect to be routinely passed over. Profiles with lots of views but no takers gradually had their search ranking priority reduced, the profile owner getting helpful system messages that an algorithm had determined that their page could use some freshening up.

Keeping his profile as private after installing the app, Tyler browsed for possible matches with a max distance of fifty miles. Having a mandatory roommate in the small, two bedroom apartment meant that the wolf wasn't going to be bringing by any strange men but he also didn't want to drive a long distance for what might end up being a wasted trip. Reading reviews for the app, some Dads apparently saw no problem using decade old photos and it turned out there could be a substantial difference between an in-shape fifty year old and an out of shape sixty year old. It usually only took a couple scathing reviews for those men to delete their profile, presumably forced to go back to hiring prostitutes.

Pulling up the gallery of profiles meeting his distance and age criteria, Tyler was like a kid transported into the middle of a candy store. Swiping eagerly through dozens of daddies, the wolf saw pictures and read brief bios that made his member grow rock hard in his briefs as he lay mostly naked on his apartment bed.

"We'll go to a baseball game. Then we'll head to my home where I'll show you how to be a good catcher," wrote a stern faced buffalo.

A page featuring a hungrily smiling lion flexing for the camera read, "I'm into skinny boys and muscle worship. Lick my abs right and maybe I'll push your head down into my lap."

An older brown mouse in a business suit held up a glass of wine. The unexpanded version of his bio said, "Looking for a hung boy to squeeze into a tight chastity cage. I'll bring the lock, you bring the blue balls."

Tyler was practically panting as he read on, eyes twinkling in excitement. This was what he'd been looking for. Mature guys in their forties and fifties who knew what they wanted and confidently stated their desires. The college boy kept browsing, seeing that dads came in all variety of forms. Kind and encouraging. No-nonsense disciplinarians. And straight up fuck machines who wanted something young and cute to slip their dick into.

In no rush to lock down a match this very night, Tyler hadn't been planning on messaging any of the men in his area. That was, until he spotted BigRowdyDog's profile. The profile pictured a huge Bernese Mountain Dog holding up a pint of golden ale, the white, tan, and dark brown furred dad smug as his spread legs revealed the sole article of clothing he was wearing. A white jockstrap with an impossible to ignore bulge.

The self satisfied canine's profile read, "I fuck on the first date and always knot. Beast in the sack but I'll cuddle you real sweet after I get done plowing you. Least until I'm done catching my breath for round two. Eager to please boys only."

The wolf nearly bust a nut right there in his underwear, his palm rubbing up and down the shaft through the stretched out fabric. Worried that if he waited he'd lose his nerve, Tyler typed out a quick message to BigRowdyDog.

"U look gr8 in that jockstrap. Super hot. I'm a 20 yr old wolf pup. Check out my profile?"

The youth hit the send button and waited. After a few minutes passed he worried about how embarrassed he'd feel if he didn't hear back. That was the kind of casual rejection that these hook-up apps were known for after all.

Thankfully his phone pinged with a notification prompt only a couple minutes later, the dog's response saying, "Cute profile. Love the tighty-whities. Send me a sheathe shot and we'll talk. Not an old pic, a new one, right now. Soft or hard, don't matter."

This was moving a bit faster than perhaps he was comfortable with, but the combination of happy and horny reduced the wolf's inhibitions enough that he quickly complied. Slipping off his underwear until they lay bunched around his ankles the college boy used his phone to snap a selfie, taking a few seconds to carefully frame his pink stiffy and tight balls before clicking the button.

Drafting a new reply to go along with the attachment Tyler typed out, "I got hard seeing your photo. Take a look."

The youth's heart was thumping in his chest in anticipation but this time the response was far quicker in coming.

"Naughty pup, playing with yourself while looking at older men. Tell ya what, I'm busy tonight but we'll play soon. Here's a pic of me working out at the gym. Why don't you stroke off to it and then send me a pic of your cummy mess on your stomach. You got 10 min. Get to pumping."

Tyler's tail started wagging without him even noticing as his phone chimed with a new message, this one including a new picture. As promised, in this one BigRowdyDog was lifting an ambitious set of weights in a bench press, muscles bulging under his black and tan fur as sweat dripped off his body onto the bench and blue matt below. But for all those details all the wolf could see was that tiny slip of red peeking out from the Mountain Dog' impressive sheath, his legs wide as he made no effort to hide himself from the camera.

~This~ had been what Tyler had been craving. Pulling his phone close to his face to examine the dog's hot dad bod, the wolf squirmed out of his underwear while softly biting his lip as he ogled BigRowdyDog's light tan sack which was fully on display. Hand finding his needy erection, the college boy was already seeing himself standing next to the canine, rubbing his big muscles and encouraging him.

The man would growl with lust but finish his set, sweat drenched body smelling of earth and sex. Tyler's imagination ran wild as he rubbed himself. In his mind he was already hearing the dog gruffly explain just how far his new boy's lips would be down his truncheon of a cock. How good his lips would feel pressed against the edge of his knot. Then finishing up, the giant would stand up in all of his glory and use thumb and forefinger to grip Tyler firmly just above his sack.

Without saying a word the dog would drag him towards the gym's showers forcing the wolf to tip-toe close behind and--

Tyler didn't get the chance to finish his fantasy, the wolf's breathing coming out in hot huffs as he painted his chest and abs with long ropes of cum. Tyler's hand flew over his shaft as he half-moaned half-whimpered through what felt like one of the strongest orgasms he'd ever experienced. The man had been right, he'd made a complete mess of himself. The wolf's stomach was a sticky tangle of jizz and fur. Not wanting to risk losing his nerve after coming down from his intense sexual high the boy snapped a quick selfie which framed his tired but self-satisfied face, his spent still dripping cock and everything in between. With a few more presses of his thumb he shot the image over to his new infatuation.

The reply was nearly immediate.

"Fuck yeah, pup. Pretty big load for such a skinny twink. Alright, I'm convinced. Let's meetup this sat afternoon. I'll shoot ya the exact time and place later. What shoe size are you?"

Still dazed from his earth-shattering climax, Tyler wasn't sure why the man was asking but he certainly wasn't going to argue the point. Messaging back he texted, "8.5. U?"

This response was longer in coming and it arrived when he was mostly done cleaning himself up.

"I'm told I'm big enough. See you sat. Till then, stay good."

Tyler blushed at the response. Despite coming down off the metaphorical mountain the dog's words still made his now soft rod twitch inside his sheath.

The following days passed quickly for the wolf as he stayed busy with school work, assigned reading, and video games. When Saturday rolled around he began to get nervous at not having yet received a follow-up text and so when his phone buzzed just before noon Tyler was relieved. The message had a time, an address, and an instruction to be neither early nor late. The wolf's tail wagged at the treatment, almost desperate to have the big man run roughshod over him. This was what he'd been missing. What the other boys from school could never give him.

Plugging the address into his phone, a thirty minute drive was all that separated the wolf from fulfilling a fantasy that'd been percolating for nearly two semesters. An experienced lover. Tall, muscular. Who's no-nonsense and always says what they want. Tyler's shorts tightened around his crotch as he recalled the photo of the mature daddy, sweating as he worked out to sculpt his body.

When he arrived at the given address the wolf was relieved to see that it was an impeccably maintained home with a sizeable yard that had recently been mowed. Probably a sleepy neighborhood where everyone paid their taxes and with very little crime. Parking his car on the wide road Tyler rang the doorbell after walking up the white driveway, past the large black truck. Ten seconds later the door opened and the huge Bernese Mountain Dog from the app profile smiled down at him.

"Right on time," the man said in a powerful voice that made the wolf's knees go a bit weak in pleasure.

Shyly returning the smile with one of his own Tyler answered, "Well... you did say you liked eager to please boys."

The man's lilac, almost purple colored eyes lit up at this and the man reached out a huge hand in what was almost a handshake except that he didn't immediately let go, instead continuing to hold Tyler's hand in his.

"Name's Luther. But if you like, you can call me sir instead."

The wolf felt the dog's hand on his and blushed managing to stammer out, "Tyler. But my friends call me Ty."

"Tyke it is," replied the man already guiding the wolf inside the well kept but old fashion home.

"Wow, sweet home! Umm, sir," he added belatedly.

"Nice of you to say so," Luther said as he guided them towards the back of the house, pulling gently on the wolf's hand. "I inherited it from my grandfather when he passed away a few years back. Didn't bother to change much, he had pretty good taste and they don't make furniture this solid anymore."

Hardwood floors, brass light fixtures. While a bit smaller of a house than was the current fashion for this area it still might as well have been a mansion to the college boy's eyes. He couldn't imagine coming up with the money to even put a downpayment on a property this lovely.

"Umm, where are we going?" Tyler asked, half hoping the answer would be 'the bedroom.'

Instead the man came to a stop and said, "Right here. The guest bathroom. I left you a change of clothes inside, but first why don't you go ahead and strip for me."

The wolf's blush returned with a fury and he mumbled, "R-right here?"

The dog nodded, let go of Ty's hand and cross his arms, his biceps bulging noticeably.

"Yep. Nothing I haven't seen already, right? And go slow when you're taking the underwear off. That's my favorite part."

Keenly aware that the Bernese Mountain Dog was still fully clothed Tyler did as he was asked, half embarrassed and half thrilled to be bossed around. The man's confidence and demeanor were pure sex as far as the wolf was concerned.

First the t-shirt came off. Then shoes, socks, and pants. That left Tyler naked except for his underwear and the canine growled low in his throat. Not in anger or impatience but in lust. It felt really good to make the man happy and Ty felt an erotic charge run through him. The younger man slid his briefs off with deliberate slowness, turning his body a quarter to the right to give the big dad the best angle for his strip tease.

When the wolf was completely undressed Luther reached out and around Tyler, grabbing a butt cheek in each hand and pulling the boy in close. Feeling his pulse begin to race, the wolf panted as the canine used his dinner plate sized paws to massage his ass.

In his ear the dog growled, "That's nice. Real nice. Now be a good boy and hump my denim. Then you can go get changed."

Luther didn't leave Ty much of a choice as he used his grip on the college boy's rear to hoist him up and forward before letting him drop back down. This had the effect of grinding the wolf's sheath against the Bernese Mountain Dog's blue jeans, not quite crotch to crotch given their height difference but rather almost humping the man's tree trunk thick leg.

Tyler got hard in a hurry which was likely the whole idea. Thankfully the man's jeans were well-worn, probably having gone through the washer dozens of times. It wasn't exactly a soft ride for his suddenly erect member but neither was it too rough. Much like the daddy himself, it was somewhere in between.

Luther didn't say much during this time but at one point he did mention, "Hmmm, that feels good." Ty wasn't sure if the man was talking about his ass or his cock and he didn't stop to ask.

This went on for a good three or four minutes before the man released his grip, stepping back.

"Good boy. Alright, go get changed. I'll go make you some fresh lemonade. Then we can play."

Reaching down, the man gathered up all of the wolf's clothes in a bundle, hooking the boy's discarded briefs on a blunt-clawed finger. "Say bye-bye to these," he said as he lazily spun them around his meaty digit, a eyes glinting as a smirk played across his face. Tyler gave a sheepish wave as the dog headed off towards the kitchen, leaving his guest alone and still very much in a state of undress. He chewed delicately on his lower lip as he realized he'd just lost his phone, car keys, and the ability to walk out of here without risk of someone calling police on the strange naked man wandering the neighborhood.

He'd just have to use the clothes the man gave him, he decided. With the dog already gone around the corner Tyler stepped into the bathroom. Confusion struck as he looked around the spick-and-span bathroom. Rather than finding a new set of folded clothes, all Tyler saw was a pair of blue sneakers and a set of bright yellow socks. Checking the cabinets, drawers, and even the tub convinced the wolf that those two items were all there was to find. Apparently he and the muscle dad had very different definitions on what 'change of clothes' meant.

Picking up one of the sneakers Ty noticed a colorful rainbow disappearing into a fluffy white cloud taking up the whole of the bottom of the shoe. It was so upbeat and cheery that the wolf felt a little goofy just holding the brand new shoe which he figured Luther must have recently purchased just for him. Tyler felt goofier still as he pulled the socks and shoes on, his pink erection bobbing in the air as he tugged the velcroed straps closed.

Seeing himself in the bathroom mirror made the youth cringe slightly. The happy shoes and bright socks made him feel even more naked, not less. Tyler suspected that was the point.

Stepping out of the bathroom the wolf went to track down the Bernese Mountain Dog, finding him in the wholesome looking kitchen as promised. The dog had prepared a plate of sliced fruit, cheese and crackers, and an extra tall glass of lemonade. He was also now only dressed in a jockstrap having taken the opportunity to strip down. Tyler's flagging stiffy found new life as he fought the urge to drool. What a hot daddy, was the only thought that passed through Ty's head as the canine set out the food for him on the kitchen island countertop.

Spotting the wolf's arrival the dog whistled hungrily and said, "Well aren't you just the very picture of fuckable. But that can wait a short while. First, have some fruit."

Seeing Tyler's hesitation Luther rolled his eyes and said, "Look, I didn't dose the damn lemonade. I just know college boys are always three things. Broke and hungry." Pointing at the chair the dog instructed Ty, "Sit. Eat."

Feeling relieved after being reassured, the wolf did as he was told and sat in the wooden kitchen chair with a quick 'thank you' and then asked, "You said three things? Broke and hungry is two."

Placing two heavy paws on Tyler, one on each shoulder, the Bernese Mountain Dog murred with pleasure and rubbed the wolf's shoulders with a confident touch saying, "It goes without saying that college boys are always horny." Luther leaned down to sniff the top of the lad's head, pressing his black nose directly against Ty's head before taking a deep breath in. Sighing in satisfaction the dog went on to say, "You're a real cutie in those shoes, you know that? Hope they're comfortable."

Tyler nearly melted against the man's touch, the canine's strong hands massaging his shoulders in a slow, steady pattern. The stress of the unknown began to flow away replaced by memories of why he came here in the first place. To try out something new. Something fun and adventurous with an older man. A stud at any age but somehow in the prime of his life when most men would be showing their years.

"It feels... I mean, they feel great. Thanks."

"Good boy. Eat your food. Just a light snack before we burn off some calories. You didn't just drive out here to try on shoes, right?"

The wolf ate in silence, dressed only in socks and children's sneakers with an adult over twice his size giving him a back and shoulder rub. A good one at that. Luther's hands were almost magical in their ability to soothe away Tyler's worries. He sighed contentedly and stretched his neck left then right, cuing the dog to use his thumbs to work at the boy's stress knots.

"There we go, get nice and loose," Luther murmured, his voice low in volume and pitching.

It occurred to the wolf that he was turning the older man on and that turned him on. Wanting to stoke the dad's inner fire a little hotter Tyler took the canine's right hand in his and brought it to his mouth. Slipping two of Luther's fingers past his lips the student started suckling them, moaning softly as he worked the digits over slowly with his tongue.

"Aren't you just daddy's perfect little slut. Well you're in luck because this dad knows just how to treat sluts."

Tyler only moaned again in response, lapping at the pads of the dog's fingers with deliberate flicks of his tongue. Luther let him continue like this for another minute or so before interrupting with, "This is hot and all but I'm ready for the real thing. Let's get you to the playroom so I can get out of this jockstrap before I rip the thing."

The young man's feedback was apparently not required as Luther took his hand back and then, hooking arms under Tyler's knees and lower back hefted him out of his seat and into the air as though he weighed nothing at all. It was a display of physical prowess that intimidated the wolf as well as turned him on.

Moving with a purpose, the dog's long strides took them upstairs and around the corner, soon arriving at a room that seemed part nursery. Tyler blinked in surprise as a blue plush tiger grinned goofily at him from near the center of a room, finely stitched mouth partly open as it watched him with half lidded sewn eyes.

Old fashion wooden children toys lined the shelves but the college boy hardly noticed them, his attention instead focused on the fresh yellow and white polka dot diaper lying open on a small purple rug. Ty didn't even need to bother asking what the diaper was for as Luther plopped his ass down right on top of it, right in position. Now on his back, the wolf could see two faces smiling down at him. Luther's and the plushie tiger's.

"Umm, what's all this?" Tyler asked, the words instantly sounding lame to his ears even he said them.

Luther didn't seem to mind though, his smile broadening to take on a feral tinge as he knelt down beside his guest.

"Should be pretty obvious, yeah? I'm going to put you in a diaper."

Something in the way he said it made Tyler feel even less at ease. It very nearly came off as a threat, like the way some movie tough guy would tell their soon-to-be victim, 'I'm going to put you in a cast.'

The Bernese Mountain Dog didn't give the wolf much time to consider the situation before he hooked both thumbs at his jockstrap's waistband and said, "Hey, Tyke. Feast your eyes on this," and tugged the clothing sharply down.

Without ceremony or pageantry Luther's knotted cock tumbled loose of its confines. It was an immense appendage. Knotted, veined, a dark red hue, and its ponderous mass made it swing side to side until it came to rest inches from Ty's muzzle. For a moment all the wolf could think of was the reaction Axel Throb elicited from his playmates when he stripped out of his shorts and showed them his girthy package. Apprehension. Loss of confidence. Fussing and self doubt.

"Hope it looks tasty because I'm told it's got a strong flavor. We'll slap some lube on it before I slip it up ya but I want you to spit-shine it first. Here, work on this and build up some saliva." As he spoke Luther wrapped a heavy arm around the boy's shoulder and with his other hand he popped a pacifier that he must have had waiting nearby into Ty's mouth.

It seemed incomprehensible to Tyler that the canine was seriously entertaining the notion of putting that blunt headed weapon of a dick up his hole. The math just didn't work out and from a biological perspective the idea was ludicrous.

"W-wait," the youth said letting the pacifier fall from his mouth, trying to slow things down. "I think that may be a bit too, ummm, big"

"Oh it's way too fucking big, kiddo," Luther said, rubbing his thumb possessively over Tyler's shoulder with near bruising force. "But we knew that going in. Least I did, anyhow. Take a closer look, champ. This red rocket is gonna wreck you real nice like. I'm talking total demolition."

The wolf's spit slicked pacifier tumbled further down his chest as the increasingly panicked boy tried to sit up, the huge brute easily holding him down against the downy-soft blanket.

( Animation #1: http://www.furaffinity.net/full/22397142/ )

Clucking his tongue softly the dog said, "None of that now. You got me all wound up and you're going to have to take responsibility. Here. Give it a lick."

"Luther, please... you're scaring me."

"That just means that maybe you're not as naive as you look. Listen, boy. You don't have to be scared. You just have to do as you're told. So work that tongue or I'll spank your ass before I fuck it."

With a quick flick of his wrist the canine's cock flopped down, whacking Tyler's coin purse with a meaty thump. The wolf's whole body tensed up from the unexpected pain, his fingers gripping the blanket in twin tight-fisted clenches. Luther licked his lips in pleasure as he watched multiple intense emotions come over the young man's face. Surprise, disbelief, pain, and finally the first real signs of fear.

Luther didn't mind. The dog wanted the wolf to understand that he was fucked before the actual fucking got underway.

"I, I, I'll scream for help! Don't think I won't!" It was the only threat the lad could come up with. He'd never be able to best Luther if it came down to force. Though he was eyeing the door, calculating his odds of being able to slip past the massive dog.

Luther shrugged. "You sure that's your best move here? This house has thick walls and the closest neighbors are a ways down the road and half deaf. Plus the way I see it is, you came here for a reason. Don't get fussy with me when I'm giving you what you've been desperate for. You wanted this. So dig in."

The diaper under the wolf crinkled as he shifted his weight, trying to pull back even as Luther was speaking. The man held him steady, his crotch missile smooshing up against Tyler's closed lips. The Bernese Mountain Dog looked down at him, seemingly unhurried and completely at ease. It was his calm confidence that made the wolf relent a smidge.

Opening his mouth, Tyler took a tentative lick of the dog's member. It felt warm on his tongue and the dad nodded, accepting Ty's surrender.

"There's a good boy. A little firmer now. Use that whole tongue."

Performing as instructed, Tyler licked mechanically at first. He was conflicted to say the least but there was something undeniably sexy about pleasing the oversized tool of a dominant dad. The way Luther's eyes closed as he sighed in pleasure, content to let his partner do the work. And truth be told, if the older man just wanted to blow his load across Tyler's face and tongue, the college boy would have been fine with that. It was the threat of invasive penetration that made Ty's hole clench.

Getting this up close and personal with Luther's flag pole of an erection made the thought of any coupling silly on its face and ludicrous to consider. But the canine wasn't merely saying they'd try anyway but rather seemed certain that despite the health risks he would get his shaft inside the nervously licking pup.

"Fuck yes, that's how you do it. Lick the top too. Yeah, get that taste in your mouth. Better than your little pacifier, isn't it?"

The Mountain Dog's words brought the Tyler's mind back to his current situation. Naked, sitting on a diaper, dressed only in sneakers, with a plushie tiger smiling down at him. The man towered above him, licking his lips hungrily. The wolf saw that canine was staring at his exposed, winking asshole.

"There's a bottle of lube behind you. You got two minutes to slick me up or all you're getting down there is your own spit. Then it's showtime because you're gonna see stars."

Ty tried to protest but all he got for his trouble was a mouthful of jockstrap, the dog pushing the coarse white fabric deep into his muzzle with two large fingers.

"Hope you don't mind a little ball sweat there, Tyke-a-roo," Luther said, letting go of Tyler's shoulder and dropping a half-empty bottle of lube on his stomach. "I recommend applying liberally. Tick, tock."

Mouth suddenly feeling dry as the crammed-in jockstrap absorbed all moisture, the lad moved as though on autopilot, the whole situation feeling somewhat surreal, as though he wasn't convinced this was actually happening. Uncapping the bottle, Tyler upended it over Luther's red weapon, making the dog suck in breathe between his teeth as the cool, clear liquid spread over and down his member before dripping to the blanket further below.

"I hate how chilly that always feels. Guess I'll just be extra glad to slide it somewhere nice and warm, right? Rub it on for me. Let me feel those hands."

Reaching up, it felt even bigger than it looked. As though by instinct Tyler used his right hand to stroke the man. The boy heard mumbling and realized the noise was coming from him. He realized he'd been trying to say "please". But whether he meant "please, stop" or "please, be gentle" Tyler wasn't sure and the dog didn't even seem to notice.

"Smear it over the tip too. Yeah, good boy. Alright, good enough," Luther said, moving into position in front of his guest. "Put those legs on either side of me, just like that. Here, hug your tiger. Okay, ready or not... "

Tyler felt something hot and fat press firmly against his tail hole. He gripped the happy plush tightly as he shook his head, blue eyes wide as pressure between his cheeks mounted. But Luther wasn't looking at his face, intent instead on watching the show down below. Of overcoming the feeble resistance blunting his progress.

Using his wide black hips to press forward Luther mumbled, "Come on Tyke, just the tip. Then you'll get a breather."

The lad moaned into the jockstrap, his ass on fire. Muscles he didn't even know he had were bitterly protesting the brutal intrusion. Tyler didn't notice that he'd been trying to sit back up until he found Luther's hand on his chest easily pushing him flat on his back.

"Here we go, it's dimpling in now. You feel that? Be a big boy for daddy and push out."

Willing to do anything to make the burning ache stop, Tyler did as he was told and pushed. And with a nearly audible pop the entire cockhead and another inch besides slipped into the wolf... and then the dog kept on going. Taking advantage of the moment and the momentum, Luther slammed forward until his bloated knot was wedged against the unbelieving boy's now dilated hole. Tyler tried to scream but he felt too full to even take fresh air into his lungs. He stared up at the ceiling in shock, blinking tears out of his eyes.

Luther growled in pleasure, a low rumble which came from deep within his chest. His eyes fluttered at the intense sensation of the wolf's hole clenching around his cock in an unsteady rhythm. The pair stayed like this for a long moment, lost to time. Tyler was unable to form coherent thoughts but still he knew he'd been wrong. Oh so very wrong. He should have run naked from this house, rainbow sneakers protecting his feet even as his privates swung about for all to see.

Not entirely oblivious to the much smaller man's plight, the dog leaned down to plant a wet kiss directly on Ty's forehead.

"What a fuckin' trooper. Good boy. Good, good boy. You're something real special, hear that?"

The wolf didn't, his mind retreating into unconsciousness rather than face the pain.

Snapping his fingers a few times in front of Ty's face the dog mentally shrugged, then got to fucking. Pulling out just a bit before thrusting right back in, Luther got into a rhythm that saw more and more of his member seesaw in and out of the wolf's backside.

Tyler stayed passed out on the blanket as the older man turned his ass into a playground, watching with delight as his near-crimson rod disappeared into the boy only to reemerge in all its glory seconds later.

Under his breath and between huffs of air Luther taunted the youth's hole saying, "All the way out... and back in. Out... and in. Stretch it for daddy."

The boy stirred slightly in his sleep as his insides were spread wide by the dog's meat, the veined knot slamming harder and harder against his besieged sphincter with each new thrust.

The naughty side of the dog hoped Tyke would wake up just in time to get speared on his knot. Luther got his wish when the wolf's eyes flung open just as the widest portion of his knot was gripped by Tyler's surrendering muscles. With a final push the rest of the Mountain Dog's pole sank in.

Wide awake, Tyler thrashed as he gurgled into his makeshift gag. Using his muscular arms to hold the wolf's legs down against his sides, Luther smiled as he watched the boy experience a full blown freak out. The dog didn't really have a frame of reference for how much pain the lad must have been in but it had been months since he'd last manage to get his knot into somebody so he figured a temporary owie on Tyke's part was a fair trade.

And the more long-term effects? Well... that's what diapers were for. And what daddy's boy didn't appreciate a nice snug diaper?

Rolling his eyes as the pup's hysterical fit continued, the cheery plushie thrown to the side, Luther contemplated palming the wolf's mouth and nose until he passed out again, this time from lack of air. But seeing that the college kid was beginning to calm down, he decided to go another route.

Pulling the now spit-soaked jockstrap out of Ty's mouth the kneeling dog asked, "Well? Aren't you gonna thank me?"

Blinking in disbelief, Tyler stammered, "You can't--... I mean--... Huh!?"

"I can and I did. What part of 'I always knot' made you think your perky little ass was somehow the exception? Don't lie to yourself, you were looking for exactly this when you put those sexy little sneakers on. Now shut up because I haven't cum, so you're gonna wanna listen real close. The reason being, when I fill you up with my spunk one of two things is going to happen."

Seeing that he had the distressed wolf's undivided attention Luther continued on.

"Option one. You stay sweet and suck on your little pacifier while I breed you. That earns you a long snuggly hug with daddy while we wait for my knot to go down."

Tyler's pearly white fangs made an appearance, the young man unconsciously making a threat display at the bullying man's humiliating treatment.

"Option two. You act up and I fuck you extra rough. And when I say rough, you should be thinking 'permanent damage'. Then when I finish fucking your boytwat, I'm going to yank my knot out and push it right back in. Depending on how much juice I got left swinging around in these balls of mine, maybe I'll knot-fuck you. Maybe I'll just spank you. Who knows."

Luther didn't wait for a reply. Picking up the pacifier that had fallen close by on the blanket, he placed it on the tip of Tyler's tongue. When the wolf didn't immediately begin to suckle upon it, the Bernese Mountain Dog began pulling his hips steadily back, reigniting the searing pain of having just been knotted moments ago. Realizing that the gruff man may have been stone-cold serious about knot fucking him, Ty got with the program and closed his mouth, making a show of sucking the blue and yellow accessory.

The canine grunted with approval and thrust deeply back into the college boy whose eyes bulged out at the sudden change in inner pressure. Taking a good look at the vulnerable kid, Luther's lust was reignited as his well lubed cock flexed within Tyler, his enveloped knot squeezed from all sides by taut boy flesh.

Taking the wolf's wrists in his hands, the dog brought them up to his chest as he instructed, "Here, keep yourself busy and play with my tits while I hump you. I got a high pain tolerance so you can rub and squeeze 'em pretty hard but you try and pull them off and I'll slap the taste right out of your mouth."

Impatient to get started, Luther said nothing else as he leaned his massive frame over Tyler. The wolf thought he was about to get crushed under the dog's dense mass but the man supported his own weight, knees and forearms pressed into the purple blanket. Ty couldn't see anything with the man settled directly atop him but he felt everything as Luther began to rock back and forth in short, controlled arcs.

The wolf's fingers gripped the canine's pectorals, whimpering in response as his whole world was rocked two inches at a time. He almost spoke up to tell the man to stop, to once again state his case that the dog's arousal was far too large to accommodate. But this would mean going against his hook-up's stated wishes and spitting out the pacifier. A jolt of anxiety shot through Ty as he decided that the man might make good on his word and knot-fuck him, damn the consequences. Rededicating himself to the least terrible option, the boy settled in to ride the situation out as Luther in turn rode him. He began delicately playing with the older man's nipples, stroking the rubbery nubs with his thumbs while pawing at the well defined pecs. But whereas the wolf was delicate in touching the canine's chest, the mature fellow continued treating him as a durable sex toy, ready-made for fucking.

The pair worked in tandem, both working to get Luther off. Tyler's toes flexed inside of his whimsical children's shoes as his insides rearranged to accommodate Luther's invasive girth. The wolf blushed in shame as he became aware of his own stiffy pressing into the dog's warm stomach fur. Lost in the initial barrage of sensations, with a grunt of his own Ty finally noticed that the top's knot was pulverizing his prostate in a manner that was both intensely erotic and quite concerning. Not aware of the gland under normal circumstances, the current bout of knotted deep dicking made it feel like his prostate was being crushed under an especially firm grapefruit.

Tyler's member apparently loved the treatment but the wolf's surprisingly durable insides protested the unrelenting abuse. Luther was either unaware or he just didn't care that the boy was struggling to fully accommodate his red hued sex piston. More likely the latter Ty decided as the Mountain Dog huffed half-grumbled words close to grey furred ear. They came out in huffs, the utterances giving the impression that the dog's attention was elsewhere.

"Yeah.... Fuck yeah."

"Take it, boy. Take it deep for daddy."

"Like that? You sexy slut."

"Fuck that's tight."

"Let daddy in. Yeah, all the way in."

The barely audible words continued to pour out in a steady cadence, timed with the large dog's short, controlled thrusts. With the canine's frame boxing him in, Tyler felt trapped in place by the mature dad's fur and muscles. Not to mention the dog's knot which was holding him fast to the man's hips, pulling him back before Luther's hips shoved him once more forward.

Nothing more was asked or demanded of the wolf, save that he lay there and get bred. Everything smelled of wet masculine dog as Tyler allowed his hands to run over Luther's hulking body. Tan fur partially hid powerful muscles. Muscles that were engaged in preparing him to receive a cup or more of sticky dog cum. Ty's own knotted member twitched and flexed, close to coming despite being untouched other than the feather light touch of the canine's stomach fur.

Not entirely focused on what he was doing as he was rocked a few inches at a time, Tyler moaned in lust and confusion into the pacifier as he reached down past his spread thighs with both hands and found the Bernese Mountain Dog's hot, heavy testicles. These he gripped, then played with. Not hard enough to cause pain but certainly enough to catch the dog's attention.

"Holy shit, good bitch! Good, good bitch! Tug those low hangers, fuck yeah!"

The balls danced and squirmed in the wolf's hand and for a moment Tyler let himself imagine that he had some degree of control over the situation. That with something so valuable and vulnerable in his hands, he'd managed to even the playing field.

The feeling lasted right up to the point that Luther shifted position, planting one foot on the ground as he pushed up further off the ground. The wolf gasped as his ass was yanked off the blanket, his tail whipping around underneath him against the diaper in distress. Without making a conscious decision to do so, Tyler let go of the dog's babymakers and grabbed onto his forearms. All of the wolf's weight was now supported by his shoulders, head, hands, and overfull knotted ass.

"Buckle up, kiddo," was all the Mountain Dog advised before starting to power fuck the college boy. He didn't even bother to spare a glance down at Ty, his unfocused eyes looking off towards the far wall as he drilled his already overwhelmed playmate.

"No! Wait! Ahh, fuck! Please! Sir!" Tyler pleaded, ineffectively. His colorful sneakers swung back and forth through the air in a sharp, steady rhythm as he was bred.

The lad held on as best he could as he was ridden by the daddy whose grunts and forceful thrusts signalled that Luther wasn't stopping until he'd had his fill. Ty had just presence of mind enough to wonder what was slapping his ass, blushing furiously when he realized that Luther's balls were smacking against his split cheeks repeatedly.

Time became meaningless as Tyler's muscles began to burn from use, stiff from holding a single position. He felt exhausted from the high intensity use, the largest dog he'd ever met turning out to be some kind of barbarian driven to dominate and fuck. The wolf decided he had to do something before he was well and truly fucked apart. And so he said the words that he knew the daddy wanted to hear... and that some unignorable part of him wanted to say.

"D-daddy, I need your cum! Please daddy, fill me with your spunk!" the wolf begged, echoing Luther's earlier words.

Luther growled, then howled as Tyke's submissive words struck a cord deep within him. His thrusts went from aggressive, to needy, to desperate as the wolf's ass squeezed down on his knot. The canine came so hard pain blended with pleasure but in his primal state he embraced the ache. His balls drew close up as they pumped potent cum deep inside the boy.

Tyler didn't feel anything change at first until a few seconds later when a distinct warmth filled him, growing out from his stomach. Staring up at the sweaty fuck machine, all of Ty's senses were bombarded by the grunting, cumming beast of a man as his own cock succumbed to the unrelenting prostate abuse. Unnoticed by Luther, the wolf's stiffy energetically squirted its own contribution as his eyes rolled back into his head. The much smaller load appeared over the course of six high-pressure jets, wetting his fur as Luther kept on cumming inside him.

Tyler came to in a semi-conscious state a few minutes later, intuiting that he must have briefly dazed out as the pair were now laying in a different room, on Luther's king sized bed. Gone was the pacifier but the shoes and disgustingly happy plushie remained. The yellow diaper was also nowhere to be seen but that may have been because dog and wolf were still joined, the dull pain of the inflated, over-large knot bringing him back around.

They'd shifted position as now Luther's gorgeous eyes looked directly into Ty's big blues. His huge arms wrapped protectively around the boy, the dog kissed him on the forehead and said in a warm, praising voice, "What a champ you are, my little stud muffin. You took daddy's cock, knot and all, and didn't make a peep of complaint. Fuck, you even came without me having to reach down and stroke your piddly-diddly. So, I take it my little Tyke had fun too?"

Luther sounded genuinely curious to know the wolf's thoughts and Ty was having a hard time reconciling the big-dicked tyrant daddy from earlier with the big-dicked affectionate dad he was holding onto now.

Deciding that perhaps the truth was best Tyler replied, "It was a bit... scary. You threatened to spank me and knot-fuck me and--"

Cutting him off with a kiss, Luther pulled back after a moment or two of gentle tongue probing to answer, "Aww baby, daddy was just a bit pent up was all. And you were so cute in your little fuck-me shoes. I promise I'll go a little easier on you until you're ready for the serious stuff. Maybe you'll even like being spanked. Cumming all over my leather chair while I paddle you good, hmm?"

Ty wanted to exclaim that it sounded awful except that Luther was distracting him by thrusting his hips forward. The dog's knot ground into the wolf's complaining prostate and, unbidden, Tyler's pink erection made an immediate return. His muzzle burned in shame.

Luther's knot took another twenty minutes to deflate and he spent the time showing the wolf just how big and strong his muscles were. With the wolf's hands touching and squeezing the muscles through the fur, the canine would explain their formal anatomical name and outlined the various gym routines he used to build them up. Tyler pretended more interest than he felt and this seemed to please the dad.

When the knot finally popped out, Ty thought his stomach might follow suit. He felt cavernously empty as cum gushed out from his suddenly soggy bottom. Luther had him in the diaper before he knew what was happening, the dog's practiced motions finished before the wolf could protest. Also produced was a striped red shirt which the dog tugged over his head. It was way too small a fit and didn't even come down far enough to cover Ty's midsection.

"Luther...," Tyler began.

"Shhh," the smiling dog said. "And call me daddy."

Picking the wolf up into his arms, Luther effortlessly held the diapered boy aloft as the man walked in a wide circle around the bedroom. Coming back around to the bed he picked up the tiger plushie and handed it to the well-fucked boy. The young man blushed as he noticed the warm puddle of cum that he was sitting in, caught by the happy colored diaper.

The man continued to stroll, bouncing the wolf gently as he went. The steady up and down motion would have been soothing, were it not also helping gravity do a number of the boy's insides. The last of Luther's cum had easily dribbled out soon after this little ride had started, and now a heavier feeling was growing. What started as vague twinges in Tyler's stomach intensified at an alarming pace until his abdominal muscles were cramping. The wolf started squirming in the Mountain Dog's arms as he identified the sensation: an intense need to use the bathroom, except it was coming on far faster than he'd ever experienced. Now it already loomed right before him, filling the horizon like a rogue wave.

"Daddy!" Ty said, his voice alarmed as he began to feebly squirm. "I can't hold it. I need... I need to..."

Luther's smile grew into a grin as he patted Tyke's rear possessively, holding the other male close.

( Animation #3: http://www.furaffinity.net/full/23496939/ )

"Just a side-effect of getting plowed by a real man, babe. Let it all out and when you're done we'll wash you up and swap out your diaper for a fresh one. Then daddy will fire up the grill and cook us up some hamburgers. Doesn't that sound great?"

Gripping Luther's broad neck and the plushie even tighter, Ty grunted, then whined as biology took its course. The wolf had never been so embarrassed in his life and the dog wasn't helping matters by stretching the lad's bare legs further apart. The big canine kept speaking in encouraging tones as Tyke tensed up against him and then relaxed, defeated. The man praised the boy as he filled up his very first diaper, not letting the college kid forget for a second that he had an audience for the humiliating, ego-crushing act.

"It's okay to cry, boyo. Daddy's got you."

Ty sniffed and whined but he didn't cry. The man's arms and body felt so warm against him as the Mountain Dog murred, his face rubbing against the wolf's neck and shoulders.

"Don't worry. Diapers aren't all bad," Luther said, his voice low and comforting. "Sometimes making a mess can be fun..."

The wolf didn't take his meaning until one of the canine's catcher's mitt sized hands came around to knead the front of his diaper, the pressure focused in a tight area directly on top of Tyler's sheathe. Had he not been soiling himself at that very moment the boy might have stood up for himself. Instead he only sniffled, then sighed as the pads of the other male's fingers moved in a small circle, rubbing the unseen but growing nub.

A few minutes later, Tyke had forgotten all about feeling sorry for himself or about how much his ass hurt. He was too busy moaning out an orgasm, making a jizzy mess as his daddy squeezed down a bit too hard on his knot through the diaper.

===============

Two months later Tyke sat in his daddy's' lap, the giant dog's erection curving deep up his rear as the canine's knot lay in wait just outside of his stretched hole. Luther's wide paws gripped the wolf's sides, threatening to tug him down onto the red bulb of flesh without notice as the man had done before.

Looking over his boy's shoulder the Bernese Mountain Dog teased, "Do it. Prove you don't need daddy to get you off and we'll skip tonight's oral lesson. Come on, rub that toy weiner. Make it squirt and you can watch the movie with me on the couch instead of kneeling on the carpet. I won't mind. It'll be a nice change of pace not to have to strain to hear the soundtrack over your gagging."

Having spent the last three evenings getting his throat stretched and bruised by his daddy's scary thick cock, Tyler was borderline desperate for a reprieve. The wolf stroked his pink member just as he'd done so many times before, if perhaps a touch faster. His face scrunched up in concentration as his hand flew up and down over his arousal.

( Animation #4: http://www.furaffinity.net/full/26195976/ )

As always it felt so indescribably good to play with himself. Even more so with his daddy's fingers rubbing into his fur, the embrace both encouraging and possessive. The dog wanted to see him cum. Or perhaps more accurately, the Mountain Dog wanted to see Tyke do his best to try and cum.

Despite his best efforts to keep his wolfhood up and hard the college boy felt his stiffy shrink in his palm, slipping back into his sheathe. Soon there was nothing left to hold onto as only the barest portion of pink could be seen poking out shyly from the entrance to his undersized sheathe. Between the pavlovian sexual conditioning he'd been on the receiving end of over the last few weeks and the trauma experienced by his once pristine prostate getting repeatedly smashed by the canine's biggie-sized meat, at some point Tyler had discovered he'd lost the ability to self satisfy. Though Luther never tired of watching him try.

The wolf was thoroughly emasculated, blushing as his failure to perform was front and center for both men to see. But rather than being disappointed Luther grunted hotly in his ear, his own erection growing harder under Ty's tail. Whether in anticipation of the pitiful noises the wolf would make as his paternal hand guided the young man's head further down into his lap or excitement that he'd now get to reaffirm why cute boys like Tyke needed heavily hung daddies like himself, Tyler wasn't sure.

Nor did he have much time to consider it as Luther jerked him downwards, wordlessly and without warning. Tyler's anal ring burned in protest as the knot rudely made itself at home. Likewise, the wolf's prostate shuddered as it was pummeled into submission yet again.

Immediately the boy re-erected just as he'd been conditioned to. The dog knew his way around the old beat-up acoustic guitar in his garage, but it was Tyke who had become his favorite instrument to strum and tune. The wolf whimpered as the spike in pressure forced a stream of urine from his bladder, out of his stiffy, and down onto the waiting diaper which had been left open in preparation to catch the golden tinged liquid.

"Again," the dog growled in his ear. "Prove to yourself how useless you are at taking care of your needs. Then we'll move in front of the mirror so you can watch yourself moan as daddy makes you cum three times in a row."

Tyler's ears twitched nervously at this declaration as Luther's hands shifted to rub his thighs and stomach. Shooting his load once would be glorious. Twice would be intense, if difficult. Three times would be a sweaty, brutal slog of raw nerves, sore muscles, and aching balls. But Tyke knew better than to say 'no'. After all, he didn't want to earn himself another spanking.
