Custom Fit (MM story: college, muscle, bulge, size difference, and growth)

Josh Taubes would be a decent model for Mikey.

I actually don't see Mikey being this enormous heavily muscled bodybuilder...yet. I picture him more as having a classic bodybuilding physique. Think a young Chris Bumstead or Urs Kalecinsky. Huge, but not colossally thick and huge like open pro-bodybuilders. Being a young guy, even if he's decently muscled, he's going to seem ENORMOUS being among young skinny college guys. Right now there's a plethora of very young classic bodybuilders that I could picture him being among the likes of.

Here's a few tall "classically muscular" young men you can find on IG: Breno Friere, Austin Keil, Wessley Vissers, Maciej Nabaglo, Guilherme Filpo

Of course, with his growth, I hope he continues to put on muscle mass and becomes a truly HUGE guy, but that's my preference :D
Another aspect that makes Josh a good Mikey model is that he's quite blessed in the bulge department.

I also picture him as a more aesthetic guy, and not at all like an Open Division bodybuilder, who tend to be somewhat ugly honestly. In any case, we're discussing a fantasy story y'know

This is one of the best stories I've read on this site. Great pacing, great development of the characters and the story. Thank you so much for posting this.

I do have one question, will the growth aspect of the story be re-addressed? In the earlier chapters it was mentioned how Mikey was actually growth bigger all over, not just his cock. Is he still growing slightly taller? Is he growing more muscular and heavier? I would assume he is due to his constant bodybuilding. I'd love to see this addressed. He's already huge, and man those is that muscular and growing ever so slightly taller would be impossible to miss. Would love some confirmation of this. Perhaps a height measurement would be cool too. Just a suggestion! Love the story either way.

I ended up stepping back from the growth aspect to focus on character, but we're definitely due for a re-measuring. Mikey is already pushing the lines of fantasy with his size at his age (as you've observed in another comment), and his spontaneous growth spurts were an extension of that fantasy. But the scene was jarring and out of place for some readers and it felt divisive to continue.

I'm working on a full-blown growth fantasy story that's more squarely placed in that sub-genre and will hopefully be less divisive for readers, but there will still be aspects of growth and change over time woven in (not just for Mikey, but Mikey's effects of those around him). Adam is getting stronger in more ways than even he realizes.
 
As a matter of interest, does anyone have a real life reference in mind for Mikey? I know he's described as huge and extremely muscular but in my head it almost gets comical

I definitely have a few references that are my go-to for Mikey inspiration, but I also like to leave a lot up to the readers and their imaginations. I love seeing how other's visualize the characters, so thank you for posing this to the thread!
 
I am so looking forward to the next chapter! @Humblebrag88 you are an amazing writer! You are definitely tied for my favorite of all time (alongside @thehottestmenxx). There are only 2 authors who've made me hard as a rock with every single chapter, and, if the next chapter is as amazing as the rest, you'll be the GOAT!!!!!

CanNOT wait to see how you rock a full-on growth story.
 
Chapter 19 (part 1)
“Holy shit that was fucking amazing!” Sid almost shouts, slapping my back in the locker room. “That was so hot, and so fucking well-deserved.”

We’re standing in the locker room, undressing in our row. I worked up quite the sweat, it being my first workout ever, and it feels awesome to peel the wet t-shirt off and toss it aside. I’m so relieved by the cool air on my skin that I don’t even think about covering up right away. Sid is boisterously excited. I think he’s a combination of stoked and horny, judging by the way he’s looking at Mikey. He shucks his shorts and I can see his cock head, fat and heavy, bouncing around with his movements.

“See what I told you?” Eli says to me, chuckling and shaking his head, “Some guys can’t handle the big man.” Eli then removes his gym shorts, showing off a pair of gray briefs, his long shaft clearly visible tucked to the side along his hip. Soft, we’re about the same size, I’d guess.

“Yeah, and some guys want to handle the big man so desperately they come in their shorts.” Sid laughs. Mikey smirks.

Mikey is quiet, but intense. Looking at me with pure need in his eyes as he removes his sweats and jock with one push. His monster softie (semi is more accurate, hanging a heavy and floppy 9 inches) bobs free in the cool air of the locker room but shows no signs of shrinking. I glance over and see Sid looking at it hungrily. I glance the other direction and catch Eli stealing glances. Even straight men can’t help but look, I’ve noticed. Once naked, Mikey stands for a moment, just breathing, steam rising off his skin. His pump is insane, his heavy pecs rising with each breath, framed by massive delts. He rotates a shoulder, loosening up the tension there, incidentally showing off his peaked biceps and triceps as he moves through positions.

“You’ve got some pain?” Eli asks, moving behind Mikey and palpating his shoulder muscles a bit.

“Yeah, you’ve found it.” Mikey says, rolling his shoulder into Eli’s hands and sighing a bit as the slightly smaller man massages the area.

“This is what you get for fucking around.” Eli chides, “Pushing that hard that fast is never a good idea, even if you’re a superhuman muscle beast.”

I watch Mikey’s cock flex at those words, and chuckle to myself. He’s pure testosterone and adrenaline right now, and the only thing that’s going to help is an orgasm. Or five. Fuck, it’s going to be along night and my body feels like I just pushed a boulder up a hill in hell.

“Let’s hit the showers and get some hot water blasting on that shoulder.” Eli says, dropping his boxer briefs.

Sid and I finish stripping down as well, Sid gives his plumped up semi a discreet tug and leans close to whisper to me.

“I wanna suck Mikey’s dick while you fuck me.” Sid says, his breath hot against my ear.

I feel blood flow down to my cock, now fully out for everyone around me to see. I feel my cheeks get hot and try to keep myself from inflating to full mast in public.

“Alright then,” Sid laughs, slapping my back again, making my flopper, well, flop. “Let’s hit the showers!”

With that, he tosses me a towel, tosses another over his shoulder, and leads the naked march across the locker room to the showers. Eli follows suit, and I get a great view of their asses side by side. Sid’s full and bubbled, bouncing with each step. Eli’s high and firm, clear muscular definition at his hips as he walks. Mikey sidles up beside me and I glance up to his beaming smile and hazel eyes sparkling. He puts his hand on the small of my back, leans down and kisses me. His kiss is strong and he holds me for a moment before breaking.

“I’m so proud of you.” He says, and I can feel his earnestness.

“Thank you. I’m so fucking lucky you’re my boyfriend.” I reply.

“I’m the lucky one.” He says, after kissing me again. “This is me checking in. Are you still good to be naked right now? Shower with the guys?” Mikey says.

“Oh. Huh. Yeah. It actually feels kinda normal, when everyone else is naked too.” I say glancing down at my nakedness. Then, “If only Sid would stop trying to give me a full on rager every chance he gets.”

“HA! Yes. He does that to me too. This chubbed softy makes the walk to the shower pretty fun, if I’m being honest.” Mikey says with a smirk.

He grabs a towel and leads us side by side through the locker room. Mikey’s muscle-saunter is usually pretty subdued. He does a lot of range of motion exercises and tends to walk pretty fluidly. Right now, post pump and fully in his dominant mode, he’s moving like a classic bodybuilder and his massive semi is swinging hard. I hear it slap his thigh and feel my own cock push another half inch toward fully erect.

As he passes each row I see multiple guys' eyes rise up, unavoidably drawn to the hulking beast. I see each of these men go through the same process, hitting the same beats like clockwork: a guy senses Mikey, looks up, sees muscles like he’s only dreamed of having, looks impressed and a bit overwhelmed, tries to process the giant form, and then invariably his eyes move down to his enormous cock, and their jaw drops just a little. I watch it happen again and again, and the more I see it the more it feels like I’m watching it in slow motion. Their eyes wide, a mix of shock and fear and desire washing over them.

“Fuck, you weren’t kidding.” I mutter.

We reach the showers and I’m pleasantly surprised. The room is larger than I expected, tiled in bright orange that had to have come from the 70’s. The ceiling is higher than I expected, but there are no windows above like in the locker rows, just recessed can lights with bright amber bulbs spaced evenly throughout. The warm light cuts through the steam, giving the whole space a glow that any gay guy would call flattering. I step down onto the tile and scan the room. There are shower heads and valves on the wall to my left and straight ahead, but the right hand wall has a row of shower stalls, including a large accessibility stall on the end. These have curtains, but the guy using one has left it open. There’s two guys straight ahead standing side by side and chatting in the spray. Despite the ample space, Eli and Sid make a beeline to the far corner, and systematically turn on four shower heads (two on each wall of the corner) and crank the heat.

“It creates a sort of heat bubble.” Mikey says, gesturing towards the corner. “Plus, you know, good for talking.”

“You guys have a whole system.” I say, impressed, and fighting the sting of feeling left out.

Eli sticks an experimental hand under the water to test the temp, then steps under the water and sighs loudly in relief. Mikey and I quickly cross and step under the spray ourselves and I feel the waves of heat cascading down my back and shoulders, taking the top notes of sharpness out of the ache and relaxing me in ways I didn’t know I needed. I look over at Mikey and see him beaming at me from above.

“Best shower you ever had, right?” Mikey chuckles.

“Holy fuck yes.” I mutter, letting my head roll back and wetting my hair, eyes closed and breath deep. “It feels like showering after a week of camping.”

“You camp?” Sid laughs in disbelief.

“Yup. My dad loves it. Plus we’re poor, so vacations are either that or stay home.” I reply, still half-lost in relief. “I’ve spent two weeks a year sleeping in a tent and building fires since I was 9.”

“Full of surprises.” Sid mumbles.

“Right? He’s like a human swiss army knife.” Mikey laughs. “He invented a sex position last night.”

“Holy shit!” I say, my eyes shooting open as I recall fellating Mikey while pounding his ass. “I almost forgot about that! We broke my bed. Which we have to fix before my dad notices, by the way.”

“You invented a sex position yesterday and then forgot?” Eli asks.

“Yeah. It’s, um, been an intense few days.” I reply sheepishly.

My eyes drift down Eli’s body. He’s smaller than Mikey, but leaner, and his abs are incredible. A beautifully cut six pack, framed by a pronounced adonis belt that slopes gracefully downward, forming a perfect arrow to his healthy manhood. The base of his cock sprouts from a dense but close cropped pubes, and dangles heavily in the warmth. His soft cock is a good four inches, and uncut. I realize I’m staring and glance up to his face and make eye contact. He smiles and gives me a quick wink.

“Wait, go back.” Sid says, finally breaking the silence. “What is this new sex position? Can I try it? Can we try it? Teach me!”

“Ok, so I was bottoming–” Mikey starts out, but Eli immediately interrupts.

“Really? Oh. I… just kinda assumed…” He mumbles.

“Yeah, never assume anything with gay guys.” Sid chides, laughing.

“We’re both verse.” I tell Eli.

“Like I could ever resist taking this big beautiful cock.” Mikey adds, reaching down and giving my dripping wet softy a squeeze. “So anyway, I was on my back, Adam pounding my hole, and he leans down and takes my cock into his mouth! He was blowing me and fucking me at the same time!”

“Holy shit.” Says Sid, now fully hard. “How does that even…”

“Height difference, plus Mikey’s mega cock, plus my natural flexibility, equals all new fun.” I say, matter of factly, feeling my own cock throb to attention.

“It was INSANE. I saw stars. Adam’s thick cock stretching my hole, pummeling my prostate again and again, and then add in one of the hottest blowjobs I’ve ever received.” Mikey says, getting low and gruff in his vocal range, and the undeniable beast of his cock slowly inflating and rising in front of him, pulsing larger and harder with every word. “I lost my shit entirely, tore the headboard to pieces as I exploded.”

“Well, fuck.” Eli says. I glance down and notice he’s definitely chubbed up. Maybe even on his way to fully hard. Is it possible that even straight dudes are turned on by Mikey’s cock? Or maybe it’s just a reflexive response to the pulsing call of the cock mothership. He doesn’t even seem to notice, and just says, “I don’t even know what to say to that.”

“I wanna watch.” Sid says, eyes locked on Mikey’s throbbing, foot-long cock.

“Deal. But don’t forget your pre-workout offer.” I remind Sid.

“Fuck yes. All of it. After Mikey’s muscle show I’m insanely horny.” Sid begs.

I look over and see the two guys from earlier have finished and are on the way out of the shower room. I notice the guy in the stall has turned to face us, and is slowly stroking his soapy cock, looking straight at us. Sid gives his cock a flex and waggles it at me.

“Looks like we’ve got an audience.” Mikey growls low in his throat. “Should we give him a show?”

Sid and I exchange glances, and we give Mikey the nod.

“Yeah, that’s my cue to exit.” Eli says, rinsing off the last of the suds from his armpits. “Adam, great to meet you. See you all Friday for leg day!”

“Bye Eli!”

“Great to meet you too!”

“Don’t pretend it’s not hot!” Sid calls to Eli’s perky ass as he leaves. Then, turning to Mikey and I holding out a bottle of body wash, “Will one of you wash my back?”
 
Chapter 19 (part 2)
I chuckle and take the body wash from Sid, squeeze a good amount into my palm and start to lather up his back. I work his shoulders a bit and he moans as I massage him, and I slowly close the gap between us, pressing my rock hard cock into his ass. Since Sid and I are closer in height, we line up well and my cock slips right between his cheeks. He gasps as my thick shaft thrusts up and down his crack a few times, caressing his hole. Mikey leans back into the spray and watches us play, stroking himself to full mast.

And quite the mast it is today, clearly ready for some action after absolutely dominating Brett in the weight room. His huge hand works the massive shaft, unable to close completely around his amazing girth. His mushroom head drools a fat dollop of precum as I watch him watch us.

I reach a soapy hand around to Sid’s throbbing dick, sticking straight up to his belly. I give him some slow strokes, kissing the back of his neck and continuing to grind my cock between the cheeks of his full bubble butt. I slide my hand down further and cup his heavy balls, and he moans hard as I play with them.

“You joining us, big man, or just enjoying the show?” I ask Mikey, seeing the lust in his eyes as he strokes himself.

“Oh, I’ll get in there when he’s ready for it. For now, why don’t you stretch his hole with your fat cock. Let him work up to the XXXL.” Mikey says, not once stopping stroking his monster for Sid to see.

“Oh, fuck yes! Give me that big fucking cock, Adam.” Sid consents, pushing his ass onto my throbbing shaft.

“Yeah, you want this?” I say, gripping myself at the base and lining my torpedo head up with his eager hole.

“MMhmmm. Fuck me hard.” Sid begs, spreading his feet a bit for stability.

That’s all I needed to hear. I turn him slightly so Mikey can see his face as I fuck him, realign myself and slide my rock hard cock in. I give him about half my length at first, and he moans as I feel his hole stretch to accommodate me. I run my hands up his back and grip his shoulder a bit, easing him back and skewering him further on my pole (a move Mikey is too tall for, I realize). He gasps and leans into it, and Mikey chuckles as he watches Sid’s face react to my throbbing cock inside him.

“How’re you doing, ready for more?” I ask Sid.

“Fuck,” Sid grunts, “There’s more?”

“Heh.” Mikey leans forward, chuckling and stroking his monster cock inches from Sid’s face. “Fuck yes there’s more. It’s the girth, isn’t it? My little man is packing a real hole stretcher. Buckle up, bud, he fucks like a tiger.”

Sid groans, squeezing my shaft with his ass, slowly grinding himself on it, trying to acclimate more. I move a hand to the small of his back, and guide him into a more arched position. I feel his muscles relax under my touch and rub some soothing circles at the top of his ample ass cheeks.

“Ok, fuck, do it. Give me the whole thing.” Sid says, breathing steady.

I slowly push in, inching my way deeper and deeper, parting his full ass to get maximum penetration. When I’m balls deep I stop and let him feel me for a moment.

“Fuuuuuuck. I can feel your heartbeat.” Sid moans, arching his spine further.

“You’ll feel more than that.” I growl, sounding a bit like Mikey.

With that I start a slow series of thrusts, easing myself out, then sliding back in, a little further with each thrust. His hole is warm now and he’s moaning and gasping as I slowly build momentum. I grip his hips with both hands and pull out so just my torpedo head is inside him, then drive my shaft in completely. This kicks off a rhythm of full cock thrusts that leave Sid moaning and drooling, reaching out for Mikey for stability. Mikey offers a forearm grip with his left hand, still stroking with his right, his pupils blown out with lust. He makes eye contact with me and mouths, ‘I love you.’

I grin as I continue to fuck Sid, now full blown pounding his ass in the steam and spray of the showers. I glance over and see our peeper is on his knees in his stall, stroking furiously with one hand and fingering his ass with the other. The sight of not one but two hot muscular jock boys watching me plow Sid galvanizes my cock to new levels of hardness, and I double my efforts, rotating my hips and grinding my fat shaft along his prostate. I feel his hips buck as I pummel his insides, and his moans take on an urgency I’ve come to recognize means Sid is about to bust another one of his epic loads.

I change my grip from his hips to his shoulders and stand him up, keeping his back arched as much as he can, I realign my hips to be thrusting upward. I wrap an arm around his lightly furry belly and grip his scruffy hair with my other hand, and continue to pound his eager hole.

“Oh fuck! I’m coming!” Sid shouts.

Mikey’s eyes grow wide as he watches me jack hammer Sid’s ass from below. Our eyes lock as Sid erupts, blasting rope after rope straight up from his diamond hard cock. Even in the spray of the showers Sid’s money shot has enough force to splatter the ceiling. And Mikey’s heaving pecs. And the wall behind him. The sight is too much for me and I climax, filling Sid’s guts with what feels like a massive load, my thick member pulsing deep in his ass.

I slide out of Sid, still fully hard, and he turns around and takes my face in his hands, kissing me passionately. At first I’m a bit surprised, but he’s a great kisser, and within seconds he’s got me making out with him, his softening cock dripping cum on my belly. I open my eyes to meet his gaze and see a look of pure gratitude and affection. I look over my shoulder and see Mikey looking chuffed and proud of himself, but he’s also still fully erect and stroking his nearly foot long cock with fevered need.

“Let’s finish him off, shall we?” I ask Sid, guiding us both down to our knees before our muscle god.

“Oh, fuck yes.” Mikey grunts, releasing his cock from his grip and flexing it, like a beckoning hand drawing us closer.

Sid and I waste no time, closing in and wrapping our mouths around his shaft from either side. His girth is mindblowing, and we’ve got plenty of space to play, trying hard to lick, suckle, and kiss our way to each other’s mouths on Mikey’s throbbing beast. Sid moves to my man’s huge mushroom head and stretches his jaw to accommodate it.

Mikey grunts and growls in response, leaning his shoulders back on the tile and rolling his head back above the spray of the nozzles (he’s tall enough that he has to duck to shampoo). He reaches his hands out and grips a shower head in each hand, flexing his biceps into rugby-ball sized peaks and making the veins on his forearms pop. Sid and I both watch Mikey stretch out above us, his rolling cobblestone abs twitching as we work, pecs heavy above, crowned with massive delts. Fuck, what a sight. Sid locks eyes with me and we begin to coordinate our efforts, matching pace and alternating positions on the massive cock between us. I reach around and start to tug gently on Mikey’s kiwi-sized balls, hooking a finger up to his taint like I know he likes. Sid reaches around and grips one of Mikey’s glorious ass cheeks and begins massaging.

“Oh FUCK.” Mikey mutters, voice low and husky, then just starts moaning obscenely.

I feel the spray leaving my back a bit and hear the distinct sound of metal straining. I look up without stopping sucking, and see Mikey–eyes closed, lost in lust–is wrenching the showerheads by the necks from his grip alone. His body is gyrating gently but insistently, working his cock between us as he literally bends steel.

His eyes pop open and I can see (and feel, from his massive nuts pulling up) that he’s ready to blow. He lifts off the wall, releasing the pipes and taking our heads in either hand, holding us firmly together and thrusting his hips, fucking our mutual mouths like he does his own two hands. His grip is vice-tight and unrelenting, but clearly and intentionally gentle. I only have a small moment to marvel at his deft hands going from warping metal to touching his lovers with such care before I feel the first blast of his orgasm, roiling up through his gargantuan pillar of fuck flesh and erupting out of him in a torrent. Sid immediately moves to catch the next blast, taking Mikey’s fat pulsing cockhead into his mouth and swallowing greedily.

“Fuck yes, take my load! Drink it up, buddy. It’ll make you big and strong.” Mikey roars, gripping Sid by his hair and flexing the other bicep, pumping in and out. I press my thumb to Mikey’s taint and milk the hot muscle beast for every drop.

Sid drinks like a man dying of thirst, the fat firehose of Mikey’s cock pulsing for what seems like minutes. Eventually Mikey loosens his grip and Sid releases off of his cock with a satisfied gasp. He wobbles for a moment on his knees and Mikey closes the gap between them and lifts Sid onto his feet, pulling their wet naked bodies into a hug. They’re both laughing and mumbling things like ‘so fucking hot’ ‘how much fucking cum was that?’ ‘I can still feel Adam inside me, you weren’t kidding about that girth’, but I’m only half listening. I stood up and was immediately distracted by the damage Mikey did to the showers.

The showerheads have about a 6” of steel pipe bent down 45 degrees and ending with a flared head, but the two Mikey gripped for stability is his fuck fog are now wrenched up and out, spray now sputtering and arched up to coat the ceiling. But the thing that leaves me wordless is the deep imprints left by Mikey’s grip. The pipes nearly collapsed from the force of his hands.

“Fuck.” Sid mumbles. I turn and see the impressed/baffled look on his face, examining the mangled heads.

“Shit. Shit.” Mikey mumbles, looking more panicked than anything. “Um, ok, I can just…”

He takes one of the warped heads in his hands and tries to bend it back in place. It bends, but the spray is clearly obstructed, and a few chunks of tile crack off by the base of the pipe.

“Fuck, that’s not great. Ok. Come on, please work…” Mikey says in a hushed tone, trying to bend the other one back. He turns to me, and I see his eyes full of shame, pleading with me.

“Babe, stop, it’s ok.” I say, reaching over and turning off the spray on the broken heads. “Like, Campus Maintenance might be annoyed, but it’s not a big deal. You’re not… in trouble.”

“Yeah, if anything, it’s hot.” Sid adds, helpfully.

“I won’t tell anyone!” Says shower lurker, startling all of us.

“Fuck. I forget about that guy.” Sid says under his breath.

“I honestly don’t think anyone would believe me if I did tell them.” He says, turning off his shower and wrapping a towel around his waist s he saunters out. “Thanks for the show, by the way.”

“Are you sure it’s ok?” Mikey asks me quietly, still surveying the damage.

“Yes.” I assure him, Sid nodding beside me. “Come on, let’s rinse the rest of this jizz off and go home. I have to study for my Geology final.”

“Ooh, come to the house! Dan took Geology last year, I know he still has his notes.” Sid chimes in.

“Sound good?” I ask Mikey.

Mikey nods, but I can tell he’s still troubled. Well fuck, the glow of that orgasm didn’t last long.
