So it's the boyfriend's birthday today and I wanted to do something special for the occasion since he's put up with me for years now. The big muscle collie is getting a heaping helping of loving courtesy of his hugemongous wolf boyfriend.

Happy buffday oldshep! Here's to getting one year larger! :3

Sunlight streams through the window blinds above Shep's desk as he was hard at work on another drawing. It was a little cramped for the 6' 2.5", 750 lb collie stud as his desk was wedged into the corner of the room by the door, but it wasn't anything he couldn't get used to. It did mean that he had to take frequent breaks as he could only stand being crammed in that little space for so long before his muscles started to ache. Now happens to be one of those times.

Pushing himself backwards out of his chair he stands up fully, showing off just how much he can make a room feel small by existing in one. The first thing he does is stretch his barrel chest by pulling his titanic arms behind him, causing his incredibly taut t-shirt to ride up his torso and onto pecs so stuffed they make couch cushions jealous. His back resembles a Greek sculpture that only the masters would have the finesse to chisel while his abs protrude like cobblestone.

Raising his arms above his head causes his already enormous traps to reach just under the base of his ears; his horseshoe triceps become more pronounced and his leviathan lats flare out wide, making his wingspan greater than most birds. He tenses his thick legs, blood vessels looking like a roadmap as they jut out. His dimpled ass is framed by the straps of the jockstrap he's wearing.

Just then he hears a knock on his door before it opens.

"Hey, are you..." He hears the voice of his boyfriend, Dark. "Oh, you're already up!" The door then swings open as far as the chair would allow it, showcasing Shep's colossal wolf boyfriend in all his glory. While Dark happens to be a few inches shorter than the collie, he makes up for it by being nearly 100 lbs heavier.

This difference causes him to be bigger in comparison to the collie. His arms push out that much further, his cannonball-like shoulders make him almost as wide as he is tall, and his abs, while mountainous, curve out into a dome of a gut. All his bulk is currently contained in a t-shirt and pair of sweatpants that look close to painted on. His extraordinarily masculine body, however, is contrasted with his boyish face and long, swooping hair, which tends to land in in front of his eyes.

"How's my wolf square today?" Shep playfully asks, adjusting his glasses.

"Alright, could be worse." Dark responds as he saunters over to his boyfriend.

"Not quite the answer I was expecting." Shep raises an eyebrow. "How could you be worse?"

"I could be a wolf rhombus instead." Dark grinned. Shep had to laugh; the wolf always had a weird sense of humour. "Though with how the weight has been piling on me I'm gonna start looking more like a wolf cube soon."

"You say that like it's a problem."

Dark rubs the back of his neck, his bicep bulging larger than his head. "Well considering I take public transportation, it kinda is a problem. When I sit down, I take up two seats and when I stand up, I block the aisle. I feel bad, ya know?"

"Is that why you've been asking me to get groceries instead?" Shep pulls the wolf in close, the heady scent trapped in his clothes becoming more apparent.

Dark chuckles. "Yeah. I was wondering when you'd notice." He leans into his boyfriend's embrace and locks lips with him. The task has become monumentally more difficult over time as the resistance caused by their ever-growing pecs forces them further away from each other every time they do it.

The collie is the first to break the kiss, his tail wagging excitedly behind him. "You're more passionate than usual. What's the occasion?"

"I think you know the occasion." Dark smiles warmly. "Happy birthday, big guy."

Shep chuckles. "I don't know if you should be calling me 'big guy'." He cups one of the wolf's pecs with a hand, feeling the rock-hard nipple nearly pointing straight down. "You've definitely got the size advantage over me."

"Well, I still have to look up to see your face. I'd say you qualify as 'big'." The wolf pushes his hair out from behind his glasses.

"I'll take it." He runs his hand down Dark's torso. He wasn't sure which part of his boyfriend's body was his favourite, but the wolf's muscle gut was always in the running. He loved the way it swelled whenever he took a breath, it made him look powerful. The way it pooched out almost as far as his oversized pecs truly emphasized just how much mass is packed on his smaller frame. "So, what'd you get me?"

"I think you'll be pleasantly surprised." Dark snerks. It was at that moment when Shep felt something pressing up against the back of his hand, moving upwards past it. He looked down and saw the wolf's wine-bottle-thick meat log, all 14" of it. He had tugged the waistband of his sweats under his grapefruit-sized balls when the collie wasn't looking.

"Aw, but you got me this last year." The collie feigned being upset, giving his boyfriend's rod a squeeze. This caused the wolf to sharply inhale.

"I can't help it, it's a crowd pleaser. Besides, the thing I want to give you is an updated wardrobe, but you continually refuse."

"There's nothing wrong with the clothes I wear." Shep stated defiantly.

"Oh, here we go..." Dark sighed in frustration. They've gone through the same old song and dance numerous times now. "Lemme start with your tops; every shirt you own is so small that they basically act like bras when you wear them. At least, the ones that still fit you." The collie looks down at his t-shirt, noting how the material is stretched so far up his torso that he couldn't pull it past his pecs if he tried. He was about to say that it still had some mileage left as it was still intact, but an errant flex of his bicep completely ripped the sleeve wide open.

"Point taken." Shep grunts.

"Then there's the problem with your pants, or more specifically how you've busted out of nearly every single one of them. Also, you've stretched your boxers out to the point where all the seams have holes in them."

The collie snickers. "I've got-"

"-Weapons of ass destruction. Yes, yes, I've heard this a thousand times already." The wolf rolls his eyes. His boyfriend was always a stubborn motherfucker when it came to this topic. "The point I'm trying to make is that you're due for a wardrobe update. You've got a grand total of one pair of clothes that you can comfortably wear in public. Don't your students notice that you wear the same thing every time you teach their lab tutorials?"

"I should hope they're more focused on the material."

"You told me that your section is the only one with perfect attendance. What does that tell you?"

"True..." The collie stud looks crestfallen. "Well, it's not a big deal. I can just pick something up the next time I'm out."

"Uh, yeah no. You're not going to be able to just waltz into 'Build-A-Hunk Workshop' and just pick out the biggest clothes they have for sale." Dark snorted. "There isn't a single store in this city or the surrounding area that carries clothes in our size. Trust me, I've checked. I have to order everything online these days."

"Is that really the only option we have? Is our city really that much of an armpit?"

The wolf snickers at the remark. "The site I use is the only place I've found that has sizes with more than three 'extra's in the name. The only other thing I can think of is to let you borrow some of my clothes for the time being, but I don't know if my shirts are long enough for you." He taps his chin in thought. "I don't think I know what the term is when you give clothes to someone older than you. Are 'hand-me-ups' a thing?"

"If it's not, it will be now." The collie raises his hand to scratch behind his ear, tearing the other sleeve in the process.

The wolf looks down at his boyfriend's choice of bottoms. "At least you're wearing the jockstrap I got you."

"Yeah, I couldn't find anything else and I kinda didn't wanna go commando." It was at that point Shep suddenly became aware of the sheer amount of cock throbbing in his hand. "You know, I've been holding this thing the entire time we've been talking. Why don't we go and put it to good use?" The collie slides his hand up and down the shaft, coaxing a few rivulets of pre out of the wolf's slit.

"I was thinking you'd never ask." Dark grins. Out of the corner of his eye he spots the jockstrap pushing up towards him. "Seems like someone else has come out to play."

"Hehe, yeah, he didn't want to miss out on any of the fun. I'm just gonna fix this real quick." The collie takes his free hand and slides the jock off the top of his cockhead. At that moment the wolf's eyes bug out as if he's able to see the succeeding events take place before his boyfriend can comprehend what he just did.

"No, wait!" Dark screams. The straps connected to the jock, now free from all that tension, fly back to their resting position, slamming the jock into the orange-sized balls of the collie.

"FUCK!" Shep howled in pain. He dropped to the floor like an anchor, both hands clutching his testicles in agony.

"Damn it! I wasn't fast enough..." The wolf bends over his boyfriend, gingerly wrapping his meaty arms around the collie's hunky body. He lifts his boyfriend like it's nothing and gently places him on his bed.

"Thanks." The collie whimpers.

"Don't mention it." The wolf rubs his hand down his boyfriend's cheek. "You gonna be okay?"

"I'll live. I'm just gonna have to remember that the straps are elastic."

"First time wearing a jock?" Dark laughs.

"Is it that obvious?" Shep chortles, the pain in his balls beginning to subside. "You know I'm still down to fuck, right?"

"Uh..." The wolf hesitates. The last time they got down to business on the collie's bed it protested something fierce. He was certain it was going to give out before they finished. "I don't know if we should do that here. It's one thing that the scale creaks when I step on it, but your bed doing the same makes me worried."

"Don't sweat it, I've reinforced it since the last time." The collie rights himself and moves closer to the wall to allow room for his gargantuan boyfriend. "Go on. Try it." Dark slowly climbs aboard the bed, careful about applying all his weight to a small area. He keeps an ear open to hear if the bed is going to give out but is relieved to hear silence. "See? Nothing to worry about."

"Huh." The wolf holds onto the bed frame and tries to shift it with all his might, but he finds it to be completely sturdy. "Wow, you did a great job here. Are you sure it's going to hold, though?"

"It will unless you spontaneously gain 1500 lbs." The collie simpers.

"You sound like you're not entirely against that idea." The wolf grabs his boyfriend's dick with a meaty hand.

"I can tell I'm not the only one." Shep reciprocates, though his expression sours soon after.

"What's wrong?"

"I'm still kinda bummed that my dick is that much smaller than yours." It had been something that bugged the collie ever since they started growing.

"Hey." Dark takes his hand and runs it along the torso of his boyfriend. "Yours is plenty big. It's still 12", so it's still like you're shoving a foot up my ass when you fuck me. Not to mention it's girthier than an energy drink can."

"Ugh." That clearly wasn't the collie's favourite analogy. "I still can't believe you made me try one of those atrocities."

"Oh yes, you were so traumatized that you went straight back to your habit of three cups of coffee a day." The wolf's words dripped with sarcasm. He takes his mitt and pushes the collie's shirt up, fondling his enormous pec. "Your caffeine addiction never truly recovered."

"Har har." The collie pulls Dark's sweats further down and rubs along his inner thigh. "I still have no idea why you're okay with drinking them."

"Because I'm young and make bad decisions." The wolf gently tweaks the collie's nub, sending a shiver up his spine and causing his shaft to throb.

"A-Ah" The collie cries out. "Hang on a second." Dark brings his hand back as Shep thrusts his arms forward into a most-muscular pose. The exertion snakes the veins across his arms, biceps bursting open the sleeves of his shirt entirely. The collie gives one last grunt as the shirt completely splits open down his back. "Ah, there we go." He removes the tattered fabric while grinning slyly at his boyfriend, noting how the display brought him to full mast in an instant.

"Okay, that was hot, but why?"

"Well it was ripped anyway, so I thought I might as well go all the way." Shep wads up the remains of his shirt and unceremoniously throws it on the floor. "Now you!"

"Uh, I'm trying to make my clothes last as long as possible, so I'll pass." Dark gently tugs at the collar of his t-shirt, pulling the taut sleeve over the peak of his bicep before completely shucking it off in one fell swoop. It's a move he's practiced repeatedly since shirts had grown difficult to remove. His pants were significantly easier to remove as all he needed to do was kick them off. The collie's tongue lolls out as he lust-drunkenly takes in the sight of his behemoth boyfriend. "I think it's time the dog gets a treat." The wolf smirks. He positions himself in front of the collie and pushes him against the wall, his boyfriend's muzzle trapped in his humongous pec valley.

"Aaah!" Shep cries out in ecstasy. His nose surrounded by sweaty, matted fur coupled with the sensation of their shafts being sandwiched between abs was about to make him lose it. Sensing this, Dark pulls away to give his boyfriend a chance to breathe. Shep then lunges forward and wraps his thick arms around the wolf. "Let's go all the way." He breathily whispers into Dark's ear.

"Aaaaah, let's go all the way." The wolf responds with a sing-song melody. The collie pulls himself back.

"Is that a song, or are you mocking me?" The collie giggles.

"It's a song that went all the way to #7 on the US Billboard Hot 100 in 1986." The wolf replies confidently. "It's actually about being disillusioned with late-twentieth century politics and has nothing to do with sex."

"You're such a dork." The collie heartily laughs.

"A dork who sweeps the music category at trivia night." Dark leans in, pushing his nose into one of Shep's muscular traps. One of his favourite things to do in this position is run his fingers through his boyfriend's luxurious fur as it serves two purposes. First, it releases the musk that gets trapped in the air pockets of his fur, nearly setting the wolf off without trying. Second, it just feels really nice, almost stress relieving. It was admittedly something the wolf was rather envious of, as, while he takes care of the state of his fur, it never turns out as effortlessly fluffy as what his boyfriend's is. It's something that just comes naturally to the collie.

"Ooh." Shep feels Dark's rock-hard rod digging between his pecs. "Someone's looking to bury his bone."

"I am." The wolf grunts. "I'm gonna need you to turn around for this." The collie does so and proceeds to peel off the waistband of the jockstrap, but not before his boyfriend stops him. "Actually, leave that on. I'm kinda feeling that right now."

"Then give me one second." Shep reaches over to his nightstand and pulls a condom out of the top drawer.

"Is that for me?" Quizzes Dark.

"Me, actually." Shep replies. "You'll be emptying your balls into me, so that means I need something to collect what I produce. I kinda don't want a repeat of last time."

"I still can't believe some ended up in the ceiling vent." Dark tries to shake his head, but his traps live up to their name and nearly prevent his head from moving at all. The collie then rips the package open and unfolds the largest condom the wolf had ever seen. "Hot damn, what size are those monsters?"

"When you have a customer ordering your wares whose dick outclasses the rest of the world, you tend not to worry yourself with standard naming conventions." The collie smirks. "I kinda like calling them 'fuckhuge'."

"Ah, my boyfriend is so huge that normal sized products can't satisfy him anymore." Dark growls, his cock throbbing in excitement. "You better hurry up then, because I'm raring to go." He grabs his pole in one hand and his tip in the other, letting his fingers get smeared with pre. He then guides his lubricated fingers to the winking pucker of his boyfriend.

"AH!" The collie yips, not prepared for the intrusion. He carefully pulls the rubber over his shaft, making extra sure not to rip it now. The opening of the condom meeting the base of his dick coincides with the wolf shoving two of his fingers inside his anus, eliciting a spurt of pre. Just in time.

"I need to make sure you're ready. I don't want you getting hurt now." Soon a third and then fourth finger make their way in, stretching the hole for what's yet to come.

"A-Appreciated." The collie moans out. He holds onto the headboard to steady himself from the anal assault.

"I think we're good to go." Dark pulls his fingers free and lines his dick up with Shep's hole. The veins throbbing on his shaft match the tempo of his heartbeat. He teases his boyfriend by smearing pre on his pink star before finally pushing through the barrier.

"Oh fuuuuuck!" The collie cries out, eyes widening at the sensation of being completely stretched by wolf dick. "Damn, I think you're bigger than last time we did this!"

Dark stops in his tracks. "Do you need me to go slowly? I don't want to hurt you."

"Nah, I just needed to get used to used to just how thick you are." Shep catches his breath before steeling himself. "Go hard. I want this."

"Whatever you say, birthday boy." The wolf abandons all ideas of going slow and just shoves his prick in as far as it can go. The sensation of his boyfriend's innards clamping around his monumental cock causes his body to tense up, his muscles flexing make him look larger than he actually was. Shep was feeling the same way with a 14" sausage deep inside him, a moan involuntarily escaping from his lips. "Holy shit, I'm totally balls deep right now! You're a trooper."

"God..."

"You're still holding up okay?" The wolf stud always made sure that his boyfriend was comfortable when they fucked.

"Yeah, I got this." The collie clutches his anal cavity around the wolf's titanic tool, this time sending a ripple of euphoria up the wolf's spine, his nervous system causing him to buckle over. "Do it again, but harder this time."

"You got it, boss man." Dark grabs a hold of Shep's shoulder with one hand and one of his pecs with the other. He starts to build up a motion of pulling his hips back and thrusting them forward. It was slow at first but sped up once they were both used to the feeling. He squeezed the hand holding the pectoral, feeling the striations of the muscle as the collie flexed it.

Shep holds onto the headboard as it was the only thing that could stabilize himself right now, his nails almost puncturing the wood. He'd be lying if he said this wasn't the hardest he'd ever been railed. He glances down at the condom and sees that it was filling up even though he hadn't cum yet. But that would change soon as he could feel the same sensation deep in his gut. "You're not lasting as long as you normally do." Shep taunts.

Dark smirks. "Well, when you have the hottest stud on the planet twenty feet away from you at all times, it tends to be difficult to do so." He hunches over the collie, pecs pressing against his muscular back as his pistoning begins to slow down. "Plus, I've been saving up for this moment for some time now."

"Aw, that's sweet." The collie pants in between grunts. "You stopped jerking off for a week just for little ol' me."

"A week?" Dark breathily chuckles. "Try a month."

"Oh shit." Shep laughs nervously at his response. The wolf's balls were big enough as is, and a month of no masturbation meant things were backed up far more than they ever have been. "You don't give a fuck about 'No Nut November' but you'll stop fapping for my birthday? I'm touched."

"It just shows how much I love and care for you." He plants a kiss on the nape of the collie's wide neck. "Plus, I'm not letting internet losers peer pressure me into not jerking off." The thrusting of the wolf's hips was beginning to grind to a halt, the tension built up in his taint was palpable at this point. "Oh fuck, it's coming." He wraps his arms around his boyfriend's neck as he feels his urethral pipe bulging with spooge. "FUUUUCK!" He yowls as the dam finally bursts, cum rapidly draining from his balls into the internal cavity of the collie recipient.

"AAAAAHH!" The collie yells as the feeling of his guts being flooded causes a chain reaction in him, bloating out the condom faster than he anticipated. His nerves were electric, firing on all cylinders due to the biggest ejaculation of his life. It took everything he had to stay conscious right now.

Eventually Dark felt the final spurts shoot out, his large testosterone factories the emptiest they've been in quite some time. He collapses onto his lover, completely spent and panting. "I hope that was worth it." He manages to blurt out between gasping breaths.

"It was great." Shep replies wearily. All his focus is on keeping upright by holding onto the headboard, not wanting to disturb the exceedingly large ball of cum still attached to his dick. "I'm gonna have to repay the favour sometime."

"My birthday's in a month. You've got plenty of time to save up." Dark chuckles, his ponderous chest bounces with every laugh. "Brace yourself now." He positions his hands on the hips of his boyfriend, signalling his intent to pull out. Slowly, but surely, he moves his pelvis away from the ample rear of the collie, taking the longer-than-a-foot dick out of his anal cavity. The collie was prepared for this, flexing his lower abdomen when the stuffed sensation left him to not let the seed flow out of him. It was a skill that took many tries at perfecting, but one that made cleanup that much easier. The wolf's dick pulses one last time before fully feeling the steamy air of the room around it.

"Damn, I think that was the biggest one yet." The collie marvels at the size of the condom as he removes it from his pupmaker, tying it up at the loose end to prevent any leakage.

"I'll say." The wolf retorts. "I filled you up so much we look like twins!" The collie attempts to lean back and see what he was talking about, but his pecs were just too massive to do so. Guiding his hand down to his abs, however, reveals that they had domed out into a gut not dissimilar to his boyfriend's. "If one didn't know any better, they'd think you got pregnant."

Shep snorted in annoyance. "Biology hasn't quite caught up in that regard."

"Well, you're gonna look the part for a little while anyway."

"And you're gonna help me explain it people, right daddy?" The collie chirps at Dark. The wolf's expression instantly sours.

"Stop that." Calling him by that nickname or any variation of it was one of his biggest pet peeves. "You know I hate that." He pouts.

"I'm just teasing." The collie playfully tussles his boyfriend's hair. The wolf retaliates by grabbing the collie's head by his fluffy hair and shoving him in his armpit.

"Let's see how you like being teased." Dark secures his arm over Shep's head, muffling the gasp the collie let out at suddenly being thrust into an abundance of sweaty hair. His olfactory receptors were going wild due to the harsh musk the wolf was producing after sexually exerting himself. The collie's shaft immediately erects, pulsating with need. It was a few seconds before the wolf let go of the collie's head, the dog gasping for air after being released from his hairy prison. He could hear his captor chuckling above him.

"You're lucky I came litres just minutes ago." Shep sputters. "Else I'd be making a mess right now."

The wolf puts the collie in a headlock and noogies the top of his head. "Not so fun now, is it!" He laughs and stops the onslaught, ruffling his boyfriend's fluffy hair instead.

"Alright, alright. I get it." The collie pulls himself out of the headlock and gives him a peck on the cheek. "Sorry to change the subject, but have you thought about what you want for dinner?"

"Huh, you're still hungry after all that?" Dark idly rubs the collie's abgut. "Shit, I don't think we took anything out."

Shep slaps his forehead in sudden realization. "Oh, damn it, we didn't!" He then rubs the bottom of his chin in thought. "What do we have that's readily available?"

"We've got eggs. We could do carbonara again."

The collie chortles. "Oh yeah, let's make carbonara for the hundredth time this year."

"Well I don't see you coming up with any other ideas." The wolf drums his fingers on his rippling thigh for a moment. "Hey, if we were to make carbonara but substitute in bologna and lasagna noodles and then send a picture of that to Gordon Ramsay, do you think he'd have a conniption fit?"

The collie bursts out laughing at the thought. "Why do you want to bully celebrities like that?"

Dark can't help but laugh in response to his boyfriend. "I don't know, I think it'd be funny. Some of them definitely deserve it though."

"True." It was a few moments before either of them spoke again. "So carbonara then?" The wolf purses his lips but couldn't think of any other idea.

"Fuck it, let's do it."
