extreme muscle growth Feeding My Dad's Growth (Feeding Another Dad's Growth-Added 04/28/2024)

[TheWeremuscleForest]

"Jake, I did it.” 

“You did what?” 

“I spiked his food.” 

“You spiked your dad’s food with...what exactly?” 

“You know...the special ingredient.” 

“Huh? You put the GH enhancer in his food?” 

“Yep. Your wish might come true, Jake. I mean, I think it is a bit weird that you find my dad so sexy, but I suppose someone has to, right?” 

“Well, he is rather good-looking Randolph. I think the dad bod suits him well, but I suppose a bit more muscle could help too.” 

“Heh well don’t wait too long to see it happen goof. He is about to eat it.” 

 

The two young 21-year-olds laugh a bit before Randolph jokingly goes into the other room to act like he is doing something. Jake goes to sit down by Randolph’s very sexy 51-year-old father Harrison, who is wearing blue jeans, loafers, and a top with three small buttons that are below his neckline. He has a bit of a pudgy belly, but it is cute, according to Jake. Harrison’s body is covered in fluffy reddish-brown hair with a light dusting of gray mixed in. 

The middle-aged man has noticed his son’s friend looking at him on occasion and it makes him blush. As he sits at the bar with Jake, scarfing down the food in front of him, he pauses and lets out a few moans. He yells for Randolph to come in so he can talk to him, but there is no answer. He then looks over at Jake and makes a few comments. 

“Did Randy put something in my chicken, Jake? This tastes better than I remember it. Actually...oh...that sneaky boy has finally done it, hasn’t he?” 

With his arms now sitting on the bar counter, Harrison looks down at both of them and smiles as he watches his forearms start to swell beneath the fabric of his shirt. He moans deeply as it gives him a lot of pleasure. Jake is also looking at them. 

“This explains why he isn’t in here right now. He did this for you, didn’t he?” 

Jake reaches over and feels the veins swelling and growing. Harrison sighs as the young man’s touch feels so soothing. 

“Mmm...I think I am going to enjoy this quite a bit Jake.” 

He jumps up from his stool and stumbles a little bit before getting his bearings again. He nervously laughs as he can now feel his legs growing inside his jeans. 

“Ahh...so this is what it feels like when you become a hulk. I hope I can give you a great show young man.” 

Jake joins him as he nearly falls over trying to stand up so he can watch in eagerness. Harrison’s biceps, triceps, and shoulders are now bulging. Massive veins pulse beneath the middle-aged man's sleeves. The 21-year-old slowly runs his hands along the growing beast’s swelling arms for a few seconds before leaning down to lick Harrison’s left bicep. The older man moans loudly. 

“Oh, fucking yes Jake. This is almost better than sex. Heck, this feels like sex to me.” 

His traps and delts are expanding now, as he grunts leaning his neck back to show it widening for his partner. The veins visible beneath the skin. He pulls Jake up to him as he feels his chest swelling as well. 

“I am becoming a beast for you Jake. I really loved this top too, but I am more than willing to hulk out of it for you. I am getting so much pleasure out of this, and I know that you are too.” 

The expanding outline of Harrison’s growing pecs is making Jake so horny that he is now reaching down to rub his own crotch with one hand and is feeling the 51-year-old's chest with the other. 

“I have fantasized about this for so long Mr. Jackson. You are so freaking gorgeous.” 

Harrison looks into Jake’s eyes and then leans over to slowly kiss the young man on the lips. He puts his arms around him and moans as he feels his huge biceps ripping through the fabric. Jake is transfixed on them as they stop kissing. The older man can feel his lower half straining in his jeans now as well. After a few seconds, the seams on them start popping loudly, making Harrison sigh in pleasure, feeling his quads blowing up in size. 

“Ahh, this feels so exhilarating Jake. Don’t call me Mr. Jackson anymore. We are way beyond that now. I will be Harris to you from now on. Mmm...fuck the anticipation of seeing what my huge upper body is going to look like is...” 

He is incredibly excited when he notices just how thick his pecs are getting. His belly has now vanished completely as his impressive six-pack can now be seen just beneath his shirt. He positions Jake to the side of him as the young admirer can feel one of Harrison’s forearms finally tear free from its sleeve. The older beast’s top is now struggling to stay intact as a few seams rip along his traps. He leans over to kiss Jake again. 

“Mmm...you are a great kisser, Jake; you know that don’t you?” 

He takes one of the young man’s hands and puts it over his growing package. The raging beast is about to burst from its confines. 

“I think it is a great time for you to meet my baby maker. He is getting so BIG!” 

Harrison grunts loudly as his cock bursts through the zipper on his jeans. He puts Jake’s hand over top of it so he can feel it as it swells even larger. He then rips his jeans open in the front so that his ballsac can also continue to expand. Jake moans as he caresses the beast in his hands, feeling the veins bulging against his fingers. 

“Oh yeah Harris, it is getting so huge. I am getting so freaking turned on.” 

“You are actually making my balls swell bigger and heavier by saying these horny things, Jake. I fucking love how much you are enjoying this.” 

Harrison has now positioned his massive furry quads to where his ballsack continues to expand as it starts to hang even further down between his immense thighs, his testicles swelling to the size of tennis balls. His glutes have also grown to nearly twice their size as well. Jake passionately kisses Harris’s huge veiny arms as he begins to stroke the older man’s huge rod. Harris moans in pleasure as he feels his chest getting even bigger as his top tries to stretch to accommodate his new size. He is now growing a lush, brownish-red beard with gray strands in between each luscious hair. 

Jake has now started to lick Harris’s big, protruding nipples on his shirt. The two swollen furry mounds of flesh are still somehow being contained within, but they are slowly rising to the sexy beast’s chin. Harris gleefully laughs as Jake chews on both of his tits as the pleasure sends his mind to places, he never thought it would go. He is leaking profusely onto Jake’s hand that is still playing with his tool. 

“Haha, don’t you worry Jake. I won’t forcefully rip my shirt on purpose...” 

As he says this, each of the buttons, one-by-one start to pop open, gradually revealing parts of his engorged, gloriously furry pectorals. He involuntarily bounces them, causing each sweaty manly balloon to start a small tear just beneath the last button. Jake sighs as he feels himself cumming in his pants. Harrison can see the anguish on his face, and he loves it. 

“I am loving that you are so hungry for my muscles, Jake. It is definitely fueling my lust for more.” 

Harrison’s back is shredding his shirt to pieces. Huge mounds of mountainous muscle emerge finally, revealing his delts and lats, which are growing thicker and wider with each second that passes. The big beast grunts as he slowly feels his abs starting to shred the bottom half of his shirt. His adonis belt has now ripped his jeans completely off his body as well. His swelling feet have also destroyed his loafers. 

“I am having trouble concentrating Harris. You are the most beautiful man I have ever laid eyes on.” 

“Keep watching me, Jake. My beautiful boys are wanting more attention as you can see.” 

Harrison has now placed both of the young man’s hands on his mammoth pecs and sighs as he feels them ripping his shirt open. The two heaving mounds glisten with intensity, his breathing labored but incredibly happy, as they drape over his swollen furry six-pack. His obliques are impressive as his gorgeously huge lats are now fully visible. Jake’s tongue quickly gets acquainted with Harrison’s erect nipples again, which are now pointing downward. The big beast laughs again as he feels an unbelievable amount of pleasure coursing through his body. 

“Oh, fuck yeah buddy. Mmm...daddy can never get enough of your appetite for me.” 

He yanks his tattered shirt off finally and is completely naked. He flexes his arms and chest a few times as Jake goes back to stroking the huge beast with one of his hands. 

“Ah, good boy. You want to make hulking Harris cum... That is such a smart decision you are making. How long have you wanted to make me cum Jake?” 

“For so long, Harris. You have no idea.” 

“Oh yeah? So, turning me into the man of your dreams, the muscle fucking daddy of your dreams is just a part of it? Mmm...I will feed you so much of my cum, don’t you worry.” 

Jake continues to stroke Harris’s huge one-eyed monster with authority, hearing the big guy moaning in delight, his body dripping in sweat. The young man is intoxicated by Harrison’s manly scent as he runs his tongue along the huge beast’s incredible abdominal cavity on up to his meaty pecs, sucking lovingly on each one of them as he stares up and smiles at the huge beast’s face. Harris hugs him in a strong embrace while letting his admirer have some control. 

“You are such a great worshipper, my boy. I think you should now move that mouth of yours down to little Harris, because he is getting ready to give you a real treat.” 

“Sure, thing boss. It looks so huge though, I don’t know how I can please him.” 

“Heh don’t worry about it Jake. He doesn’t take too much coaxing to get a rise out of him.” 

The young man takes a few moments to look at Harrison’s impressive equipment, staring at his thick furry bush, kissing his thick veiny shaft, and running his tongue on his meaty head. Harris sighs and laughs every time his partner flips his cock up and down. 

“Ahh, I’m glad you are having fun with him Jake.” 

Jake’s foreplay is driving the older man wild, and he loves how it is putting him on edge. It is making his testicles grow even bigger as they start to pump more cum into Harrison’s prostate. He is now starting to push the young man down on his swollen beast. Jake nervously tries to resist, but it is not happening as Harrison’s strong hands are too much. 

“Mmm...I can feel my seed starting to pump into my cock Jake. Drink up, my boy.” 

He can hear the 21-year-old gagging as his powerful load flows both down his throat and out the sides of his mouth. His neck muscles appear to be stretching a bit, as if his body is trying to adapt to what is happening. Harrison moans as he watches Jake trying to keep some kind of composure as he continues to get abused by the beast’s incredible white flood. 

“GOOD BOY! You are such a trooper. I wonder what is going to happen to you when I am done filling every part of your insides with my DNA. Are you going to resist it Jake?” 

After several more jets of cum leave his swollen balls, enter his thick cock, and escape down Jake’s sore throat, he lets go of the exhausted young man as he feels his emptied rod leaving his partner’s mouth. It dribbles several strands of fluid down onto Jake’s-soaked red t-shirt and black pants. He is now trying to catch his breath, gasping for air, but appears okay. 

Harrison picks him up off the floor and embraces him again, holding him close against his huge chest. Jake has now put his hands on the big beast’s arms and is caressing them. They are both smiling at each other. 

“Uhh...whew...Harris...I thought I was going to die. I am so overloaded with your cum, I can hardly breathe.” 

“I wonder what will happen next buddy. I want you to grow big and strong like me. Isn’t that what you want too?” 

Jake pauses to think about it and is getting an uneasy feeling. He has always admired muscle growth on other men but has never considered it for himself. His mind got swept up by Harrison’s incredible transformation and he wanted to look at and feel his older crush’s muscles, which did happen, thanks to his friend Randall. Speaking of his close friend, he now wonders where he is hiding. 

“With all of this happening to you, I completely lost track of where Randy is.” 

“Why do you care where he is at right now, Jake? Heh, your attention should only be on me, right?” 

They can hear someone groaning down the hall. Clearly, it is Randall, but he sounds like he is in a bit of pain. Harris has an idea of what is going on and tells him to come into the room to join them. 

“RRAANNDDYY...Did you get jealous of Big Harris and have to get big like him too? Come in here so we can see you hulkout as well.” 

The 21-year-old redhead slowly walks in. He is wearing a white tee and yellow shorts. His body has already started to grow as his quads and calves look quite a bit larger than they were before all of this started. His cock is tenting heavily in his shorts and his arms are getting huge and veiny. 

“OHH FFUUCCKK...I couldn’t resist the urge to take it, Jake. I didn’t realize it would make me feel so good either! I just crave size so much now.” 

“You are such a good boy, Randy. Our DNA is geared for hugeness. Just let it overtake your senses and enjoy the ride.” 

The young beast moans loudly as his glutes start ripping out of the back of his shorts. He stares and smiles at Jake as his pecs inflate, stretching his tee to the point that it is practically painted on his chest. His huge six-pack is also visible beneath his shirt as his lats start ripping through the sides. He is panting with excitement. 

“I want you to grow so bad too Jake. You have to join us; this feels so fucking amazing. I love the feeling of just...RRWWRR...” 

Randy’s swelling cock bursts through the front of his shorts with ease as his junk is in full view. It looks very similar to how his father’s cock looks, as his ballsack also expands to nearly twice its size. 

“Oh, well I see that my genetics have been passed down to you, son. Heh, I imagine you are going to need help with that in a little bit, right?” 

“I do dad, but I want Jake to be the one to make me cum. Mmm...the thought of him taking my load on top of yours pops is something I want to see. It has to mean that he will turn into a grotesque muscle monster.” 

The young growing beast has now walked over to join the other two as he gets ready to show them both his immense chest. Harris grunts as he sees his son’s shirt starting to rip. He is now stroking Randy’s huge cock as Jake starts to feel himself losing control. They both can sense it. 

“Good boys. I can’t wait to see you blow your load inside Jake, Randall. He is going to realize just how special he really is.” 

“Oh fuck, I can’t wait dad. RAWR! Yeah, chest fucking GGRROOWW!!” 

Harrison yells in delight watching Randy’s chest swelling bigger beside him, now completely exposed and covered in a nice fluffy layer of reddish fur. His shorts are now ripping off his swelling legs as his shirt is in tatters. He moans feeling his dad getting him close to the edge. 

“Fuck...I am going to cum. Get your mouth down there Jake, start drinking up, and get to growing already.” 

Randy rubs his big chest as he feels the cum start to flow from his big cock. Jake catches some of it in his mouth as he starts moaning deeply, feeling things happening to him all over his body. He can hear both other huge beasts grunting as they can see him swelling. The young man came in wearing a red tee shirt, black shorts, white briefs, and a pair of sandals. 

After savoring several shots of his friend’s cum, Jake stands back up and begins to embrace his growth. He stares down at his legs and calves and watches in amazement as they begin to explode in size. Father and son are sighing under their breaths. He can feel his cock expanding rapidly as well as his shorts are already starting to shred under the raw power of his muscularity. He can feel his confidence building in his head as the growth moves up into his upper half. 

His sandals are no match for his enlarged feet as they explode open. Harris and Randy yell in pleasure as the two beasts are loving how much bigger Jake is getting. They can hear his back cracking as it appears he is getting even taller. His shirt rises a little further up his chest as parts of his pelvic floor and lower abs begin to expand quickly. He moans in delight feeling his shorts ripping along the waist, exposing the top part of his briefs. Randy can see his friend’s huge cock trying to get free. 

“Come over here beside me Harris. You are responsible for creating this monster.” 

He Looks over at Randy. 

“Randy...I think my cock wants to play with you.” 

With just a few grunts, Jake’s enormous cock tears the rest of his shorts open as they fall to the floor behind him. His briefs are now the only things attached to his lower half, but that likely won’t last much longer either as he continues to expand. His glutes are swelling rapidly as well as he looks over at Harris and grins. He can feel his arms, back, and chest swelling now. 

“You are going to be the most beautiful monster I have ever laid eyes on Jake.” 

“You think so Harris? How big should I get?” 

“Oh, as big as possible buddy.” 

Randy is now working his cock over, which appears to be making his ballsack grow even bigger. 

“OH YEAH RANDY! Keep doing that, I will make you want to grow even more.” 

He looks over at the huge middle-aged beast and stares at him with intensity as his pecs and arms inflate in succession with each other. He grunts as Harris moans with pleasure watching them growing. 

“I don’t think you are going to be able to wear anything we can get for you Jake. You are going to...” 

Jake is now laughing as his bloated pecs easily rip through his shirt. His huge, bulbous shoulders, mammoth traps, and engorged triceps follow afterwards, as he continues to grow even bigger. 

“I am not worried about clothing right now Harris. I just want to keep growing. I have never felt this good in my entire life.” 

“Whoa, I don’t doubt that for a second stud.” 

He is now flexing his biceps, watching in amazement as they stretch bigger beneath his skin. He is guessing that they are as big as softballs but thinks maybe they won’t stop inflating. He then moans as his pecs continue to get wider and more powerful, pushing his arms further away from his body. His shirt is now only attached to his neck as it gets ready to destroy the fabric with its immense girth. 

“You think I am done growing, boss?” 

“I don’t know Jake, are you?” 

The hulking beast, who must be upwards of 325 pounds at this point, flexes his back, flaring his lats, touches Harris’s own amazing body and makes him swoon in pleasure. The older beast is now beating on Jake’s abs, which are rock hard and have somehow formed into a gorgeous ten-pack. He smiles as he continues to stare at his crush and leans over to kiss him on the lips. His cock is throbbing as he gets ready to drown his best friend in his own special sauce. 

“I can feel my cum rushing through my balls Randy. You ready to join the monster club?” 

“You better fucking believe I want to keep growing Jake. Make me forget what I look like now.” 

Jake laughs as he starts to spray his close friend in his cum serum. Randy gets incredibly excited as he anticipates that another growth spurt will happen at any second. He closes his eyes, stands up and starts breathing heavy, his chest heaves as he scoops several piles of spunk off his big muscles and downs them into his mouth. He doesn’t know if it must be consumed or not. 

“Ahh...I want to be big like you Jake so badly. My very existence depends on it right now. I am big, but I must be bigger...taller...fucking hung like a horse...” 

“I think you will know it when it gets to your...” 

Randall opens his eyes and starts to moan as he looks down and sees his cock getting even bigger. It is now nearly a foot long as his ballsack expands as well. He starts stroking himself again, feeling his forearms and biceps expanding larger and fuller than before. He is giddy with excitement as his chest begins inflating again, draping even further over top of his huge abs. He is now pressing himself up against Jake as they squeeze their giant pecs together and smack cocks, trying to see who the bigger beast is. His spine cracks a few times as he feels himself getting taller and adding even more muscle to his colossal back. 

Harrison loves seeing both young men fooling around with each other but is a bit jealous of their incredible massiveness. Both have eclipsed over 300 pounds, and he wants to join in on the fun, but he wonders how he will get there now. After Jake has a bit of a tug of war with his friend Randall, he composes himself for a minute or so and walks back over to the hunky mature beast and smiles. 

“We have gotten to a critical point in our growth journey Harris. You and Randy toyed with me this entire time about becoming a hulk and you both succeeded. I gave your son the tools to match me in godlike proportions but guess what.” 

Harris realizes what must happen now. He is a little bit nervous about it, but then again, he realizes that it isn’t that big of deal once he thinks about it. 

“Oh well fuck Jake. My beautiful boy must provide his old man with the family’s own growth formula by way of his godlike cock. Yeah, I think I can do it this once.” 

“Heh good, because I am sure that Randy has been wanting to blast you this entire time. He is acting like an insane beast at this size.” 

“I know you are my dad, but in this one instance, I have to think of you as some fucking gorgeous hunk that I want to grow for my own pleasure. Hope you understand that pops.” 

“Randall, fucking do it. I want to play with Jake just as much as you do.” 

The young hulk strokes his cock with both of his hands vigorously and points it in his father’s direction. He is about to do something he never thought he would ever do. Harris can already feel some of his son’s precum hitting his face. It makes him shutter as he hears Randy revving up. The streams of cum begin coating his chest and down his legs as he sticks his tongue out to catch some of the white rain. 

Jake is heard off to the side grunting, knowing that he will be getting the hulking mature dreamboat that he has always wanted. Randy finishes spraying his cum all over his father as he walks back over towards his fellow 300+ pound hulk and smacks his ass. Jake smacks him back and acts like he is about to tackle him again. Harris is still wiping cum off his body and is slurping it off his fingers. He chuckles a few times. 

“I gotta say son...you do taste pretty good. You are never going to shove that thing inside me though. I can promise you that.” 

“That is the same for you dad. Let’s see you beast out now.” 

Harris is now feeling his body start to grow again. He grins as he feels his cock getting bigger as it starts to look a lot like his son’s. He then hears his own spine cracking as he feels himself adding at least a few inches to his height. He giggles in pleasure as his lats stretch even wider and his back muscles nearly double in size. The swelling hulk moans, staring directly into Jake’s eyes, as his furry chest inflates even larger, pecs thicker, meatier than before and his abs expanding even wider. 

“Mmm Jake...I am going to be so FUCKING MASSIVE! I feel like I can grow even more.” 

His quads are forcing him to stand at a different angle because they are getting so monstrously dense and wide. His massive cock dangles between both, dripping profusely, feeling such incredible pleasure as he continues to feel his body expanding. 

“Aww fuck...YEAH! Look at my arms Jake...my fucking cannons are still...GROWING!” 

Jake is practically drooling as he watches his daddy hulk’s biceps inflate to the size of soccer balls, veins as thick as garden hoses, and his triceps are now larger than most human’s legs. Harris agonizes as his forearms stretch to equally supernatural sizes. He is much bigger than the two younger muscle freaks and he is loving every minute of it. 

“I am now back to being the dominant beast in this house boys. Now come over here my beautiful Jake and let me have my way with you.” 

“With pleasure daddy hulk. I will savor every minute I spend with you from now on.” 

Jake stomps over to Harris and they embrace, kissing each other longingly as Randy looks on. Jake looks at him and tells him to come join them for a little roughhousing. He smiles and decides that he will join them for that, but no sex with his dad. Jake understands and they start to play strength games with each other including arm wrestling, putting fists through walls, and whatever else they feel like doing. 

The house they are in will not survive the three hulks because they now feel like they have outgrown it. Between the three of them, they weigh well over 1000 pounds, and they are filled with tons of testosterone. Randy does watch his dad and Jake have sex with each other, and in a way, it does turn him on, but he must remember that this 400+ pound behemoth with his best friend is his father. 

He will get his turn with Jake as well, and they take turns plowing him. The extreme growth between them has ended. Now they will have to figure out what they will be doing once the house is in complete disarray, as these three will need to satisfy their hunger in just a short amount of time. For now, though, the three hulks are going to enjoy their newfound size and strength.

Feeding Another Dad's Growth

 

“Thomas, I can hear you lurking in the other room. Are you trying to make me nervous again?” 

“No Samir, I am just talking to one of my friends on the phone.” 

“Stop calling me Samir son, you know I don’t like that.” 

“Yeah, sorry. I know it can get a rise out of you.” 

“Thomas! I sometimes think that you have a major crush on me. Your mom married me, remember?” 

“I don’t have a crush on you. Although, it isn’t every day that your stepdad goes around baring his assets to everyone. Would it be all that surprising if another man my age did have a crush on you?” 

The 43-year-old Egyptian American pauses for a few moments to think about what his 20-year-old stepson is talking about. Thomas became his son when he was 16 after his mother married Samir. They unfortunately divorced a few years later and his Anglo son visits him intermittently, only he doesn’t know that there is someone else that also came over with him. 

“Another man has a crush on me? Heh, well that isn’t too surprising.” 

Samir tends to wear very tight clothing in public, showing off his great ass and furry body. He isn’t in great shape, but he has a decent foundation to be. He accidentally showed his cock on a couple of occasions to Thomas, who described it to his 19-year-old college buddy Gino. Since then, the Italian-born jock has made a few trips with Thomas over to the older man’s house. 

“You know about my close friend Gino? He has something that he wants to give you to eat.” 

The fit college student punches him in the arm. His deep voice can now be heard. 

“What the fuck Tom! It wasn’t supposed to be perverted like that.” 

Samir gets up from his seat in his home gym and walks over towards both young men. He spots them standing beside the doorway to the room. Gino seems a bit embarrassed. 

“Gino? So, you have a crush on me? Well, I guess that can’t be bad, can it?” 

He stands in front of them, his tank soaked in sweat, his shorts tight enough to show the crease of his huge bulge and his balding shiny head. He sees the 19-year-old holding what looks like a protein bar and takes it from his hand to start eating it. 

“Thomas, there is nothing perverted about this, he just wants to give your stepfather something to help his gains. Thanks for the great gesture and wow, this tastes really good. Where did you get it?” 

“Uh, well I know someone that makes these, Mr. Elmaqi. They have a few extra ingredients in them.” 

“Ah, well I think I am starting to feel the effects of those extra...mmm...ingredients Gino.” 

He looks down at his crotch and feels his cock straining to the point that it is about to burst through his shorts. He moans deeply and finishes the bar off. Gino steps back into a wall as Thomas’s stepfather gets closer to him. 

“How long have you had the hots for me Gino? Did you have a plan to grow me for your pleasure? Well, I am definitely a willing guinea pig.” 

The Arab man growls as he feels his legs expanding and his arms swelling. He reaches over to feel both of his biceps inflating against his fingers, veins stretching and bulging against them. He is incredibly excited as he feels his cock starting to burst out of the front of his shorts. Both young men are stunned at how big and meaty it is getting. 

“Ahh fuck boys. My balls are getting so big and heavy too. I am making so much milk for you both. Yeah...that’s right Thomas...you too. Your friend here is making me so fucking horny, and I can’t help but to crave...mmm...yeah...make me BIGGER!” 

Samir feels his chest expanding as he reaches over to rip his tank open, showing both his growing furry pecs. His flabby gut is now swelling into a thick bubble gut, which he starts to rub with glee. Gino is now starting to feel the Arab man’s expanding upper body and starts to moan to himself. 

“Yeah Gino, you enjoy my fucking ascension to alpha Dom. I want more size! AHH!” 

He pulls on the rest of his tank and loves the sound of it ripping as his back grows as wide as the doorway he entered. His ass has now completely destroyed his shorts, which he disposes of promptly. He stands nude in front of both, grunting loudly, as his cock throbs wildly. Gino has now started to lick on Samir’s swollen biceps as the furry Arab beast turns to look at his stepson. 

“My big mammoth Egyptian cock is waiting for you to enjoy it, Thomas. I know you have seen it and have stared at it in lust.” 

Thomas is watching it bounce up and down and seems to be in a trance. He is struggling to remember that he is his stepfather as he takes a few gulps and walks up to him. Samir smiles as he bounces his huge pecs and feels his cock leaking. He wraps his free arm around his stepson and pulls him into him to give him a hug. 

“It is okay Tom. Our relationship doesn’t have to be the same anymore. I don’t feel like this should hamper our...” 

He stops talking when he feels his son’s hands traveling along his back and chest. Thomas squeezes his stepfather’s huge pecs and makes him sigh in pleasure. It doesn’t take long before their eyes meet, and they kiss each other passionately. Gino has now found his way down to the beast’s huge pole and is massaging it with his mouth. They stop kissing for a few moments so that Samir can watch the Italian worship his rod. 

“MMM...oh yeah Gino. He really likes you a lot. You are making him want to thank you for your amazing gift to me. Why don’t you get down there too Tommy and help him give you both a nice wet kiss. I think I might enjoy it a bit more.” 

Thomas gets yanked down to his knees by his friend as they start toying with the older man’s big uncut brown beast. Gino smiles as he lets his buddy take his stepfather’s thick man hood in his hands and is stunned by how much it weighs and by how big Samir’s balls are. 

“I have to admit son, there is a part of me that really wants to see you enjoy getting me off. This transformation was one of the best moments of my life, but this might be even better, at least for me. It sounds wrong, but we are not blood related, and you do come to see me a lot, which is really great. You two are worthy of my big dick and whatever happens next.” 

Thomas is now messing with Samir’s cock sheath and is running his tongue along the inside of it. Gino moans as he watches him do this and is petting the Egyptian American's huge quads and calves. His stepson is also playing with the strands of precum that are starting to flow from his cockhead before slowly shoving it in his mouth to get a nice amount of saliva on it. The mature beast whelps in delight as he puts his thick paw on his stepson’s head for a few seconds. 

“OHH YEAH TOMMY! That is so fucking good buddy. You will make me lose control pretty quickly if you do that much longer. It feels so FUCKING GOOD!” 

After a few more minutes of making his stepfather squirm, Thomas looks over at Gino and winks as he passes the brown beast over to him so he can gulp on it and moans, tasting the thick gobs of precum as it flows down his throat. He pulls it out and says that he feels tingling in his throat and stomach. Thomas smiles as he looks up at his stepdad and starts to shove his monster down his gullet. 

“MMM...OHH...YEAH...you are no stranger to this obviously son. Sammy is going to feed you so much...cum...” 

Samir tweaks both of his big meaty nipples as he feels his big load moving into his cock. The 20-year-old pulls his big meat out just in time to feel himself getting coated in his stepdad’s white flood. Gino points it at himself too as it drenches him too. They both moan as they take turns running their tongues on the big raging shaft drinking the flowing milk and smiling at each other. The big mature beast is incredibly turned on as he looks at both of them covered in his thick cum and helps to get it out of their eyes and nose. 

“You are both such deviants, you know that? Now I want to see you both change. I know it has to happen, right?” 

Gino is now getting a concerned look on his face as he clutches his stomach. Samir moans as he helps him to his feet. Thomas has moved over to the side as his Italian friend quickly walks into the gym area. His stepfather waddles by his 20-year-old stepson and drags him in with them. He is holding him against his huge meaty right arm and right pec. 

“This is so fucking fun and incredibly hot Tommy. I am turning you both into huge freaks. Let’s see how big Gino gets.” 

The Italian stands a few feet away from them and starts to groan as he looks down and sees his chest and legs starting to expand. (He is wearing his college’s polo shirt, matching gym pants, ankle socks, and sneakers.) The young man is now laughing as he feels his arms and back doing the same in just a matter of seconds. He is not resisting it whatsoever as he hears his muscles stretching and inflating all over his growing frame. 

“Oh, my gawd Tom, it is the most incredible feeling. I have wanted to get big for years. The guy I got that protein bar from never told me that it would feel like this. This...is...SO FUCKING AWESOME!” 

As both Samir and Thomas look on, the Egyptian beast starts running his hands on his stepson’s private area and continues to squeeze his thick Arabian bicep on the young man’s face. Gino can see his cock rising in the front of his pants as it expands and starts leaking through the fabric. He then stares eagerly at his inflating biceps as they stretch the sleeves, pushing them further up his arm to his thickening shoulders. His lush black hair is getting thinner as he feels the stubble on his face getting noticeably thicker. 

“Does this turn you on Tom? I know I am really enjoying it. Your stepfather is the absolute best for turning me into this freak I am becoming.” 

Thomas sighs as he starts to feel himself trying to grow, but he is not so willing to just let it have its way with his body. (He is also wearing a polo shirt, but without the college logo on it, a pair of gym shorts, and flip flops.) Samir moans as he starts to stroke his big, hefty tool, watching Gino transform and knowing that his 20-year-old stepson is going to start at any moment. 

The Italian is starting to hit his alpha phase as he lets out several, “OH YEAHS!”, as his voice deepens even further, and the growth hits the pleasurable stage. He grunts in excitement as he hears fabric ripping on his pants and his top. His quads are now spilling out the sides of his shorts as he watches his pecs making a mockery out of the buttoned part of his shirt’s front. Both of his huge black-haired chest mountains are squeezed together and touching his now manlier chin as they gradually tear their way to freedom. He is watching Thomas, seeing him struggle to maintain his composure as he feels his own cock growing in his shorts. 

“LET IT GO TOM! Look how big I am getting. There won’t be a single person in my family that will recognize me now. I absolutely LOVE IT! OH...YEAH...” 

He grunts as his feet blast out of his sneakers and his socks disintegrate under the size of his growing legs and calves. He laughs as his huge cock tears through his pants and squirts a few jets of precum all over Samir’s workout equipment. The older beast moans as he pulls Thomas over to where the Italian beast is. The huge Egyptian puts his free hand on Gino’s back and feels it getting wider as the 19-year-old genetic freak’s shirt rips more and more with each additional inch of muscle expansion. 

The young beast tears his pants and shirt off revealing his huge and hairy frame to both of them. His beautiful greenish-blue eyes turn to look at both as he smiles directly at Thomas. He can see the fatigue on his best friend’s face as he pushes Samir’s arm away from him for the time being. He pulls the 20-year-old into his enormous arms, flexing his 24” cannons around his best friend’s sweaty back, and is trying to calm him down for the time being. 

“Tom...look me in the eyes. Don’t you want to get huge and powerful like me?” 

“I... uh...good gawd you are getting so massive Gino. Your man tits are literally going to smother me. I... I think I do want to, but there is a part of me that is really afraid.” 

“Just grow brother. I want to see you turn into a mass monster like me. Then, we can both take turns on your stepfather. That was the plan, right?” 

Samir moans as he hears Gino saying these things and shoots several more jets of cum all over the two young men. The Italian hulk yells in delight as he sees and feels his close friend starting to swell against him. Thomas now has his expanding arms wrapped around his best friend’s huge torso as they begin to test the limits of his sleeves. He can also feel his back cracking as he starts to get even taller. His swelling feet are now starting to smash his flip flops to bits. 

“OH, FUCK YEAH TOM! Embrace the hulk within you. You won’t regret any of this.” 

The growing beast has now started to growl as his inflating pecs and rapidly swelling back start ripping through his polo. The two other behemoths moan loudly watching him get freaky huge. His quads are now destroying his shorts as his calves double in size in seconds. Gino has now leaned in to start rubbing on his hulk buddy’s mountainous chest and is kissing him on the lips. Thomas is now growing a thick, brownish layer of fur on his face and body as he gleefully starts lifting his friend in the air. 

His shorts are now falling off him as he reveals his mammoth tool, which is now at least 11x7. Samir rips the rest of his stepson’s top off as he gets behind him and starts to massage Thomas’s huge glutes with his big Egyptian tool. The swelling beast stops kissing Gino to turn his head to speak to his stepfather. 

“What do you think you are doing, Samir?” 

His voice is now incredibly deep and masculine, which is exciting his Arab stepfather to no end. 

“OH...FUCK...Tommy...you are making me crazy right now. I have to conquer your gorgeous ass. It is calling to me.” 

The huge beast laughs as he arches his big butt down to let Samir enter him. 

“You are totally responsible for what you are about to do to me then, old man. I want you both inside me. Let’s make this happen.” 

He grunts loudly as he feels his stepfather’s big brown cock sliding inside him. He starts kissing Gino again as he grinds against the Egyptian’s huge man meat, who is in absolute heaven. It isn’t long before he feels Samir’s cum filling his insides. He is now slowly stroking his best friend’s big tool to prepare him for entry inside him as well. 

“OH SAMIR! You have been a really...bad...daddy... You are now turning me into a literal muscle god.” 

Thomas is now starting to grow again as his stepfather sighs feeling his son’s hole loosen up around his big penis. Gino lets go of his friend as he steps back a little to watch in awe as his best friend inflates even larger. The lust is evident in the beast’s voice when he repeats, “Bigger...YEAH...BIGGER...FUCK YES...MORE...Put your big dick inside me too Gino. Fill me up and I will feed you both my god seed.” 

Gino rushes over and squeezes his big rod in with Samir’s as the two beasts moan feeling their tools rubbing against each other. It isn’t long before the Italian hulk unloads inside Thomas, which prompts him to expand even bigger. The godlike muscle monster is now getting close to hitting the ceiling with his huge hands as he laughs hearing the room creaking. 

“You are both beyond worthy of my big...fat...load. I can’t be a god all by myself here. Gino...let me bathe you in my boys.” 

Thomas pulls their cocks out of his sloppy hole and turns around to slowly stroke his massive 18x12 schlong above his best friend’s head. After just a couple of minutes, Gino can feel himself getting drenched in the beast’s white rain. He quickly starts slurping it down his throat and feels himself growing rapidly. Samir is trying to get some of it too as he starts scooping it off the inflating Italian beast. 

“HAHA! Oh yeah Samir...enjoy the rush of growing into a monster.” 

The Egyptian laughs hysterically feeling himself swelling bigger as the room struggles to maintain its shape. The three gigantic hulks are now about to explode out of the walls. After Samir finishes his growth spurt which has him reaching nearly 9’ tall and over 550 pounds, he makes eye contact with the other monsters, and they knock some of the walls down in the house. The feeling of drywall and tiles hitting their tough skin excites the three hulks greatly as they playfully continue to destroy the property. 

In the distance, Gino can hear other incredibly deep voices from across the city. Thomas smiles and grabs his stepfather to drag him over to where his Italian best friend is standing. The three monsters, which weigh a combined 1800 pounds, and are between 9-10' feet tall, have their arms around each other and kiss for a few moments before making a few comments. 

“Can you hear them, Tom?” 

“Holy shit, I can Gino. There are more of us then?” 

“I hope there is another hulk like me boys.” 

“That would be awesome, Samir. One daddy is great, but two is even better.” 

“Wha...whoa...that looks like...FUCK YEAH...it is Randolph.” 

“OH...I know him. He told you about the protein bar then?” 

“Yep. It looks like Jake is with him and... mmm...a hot older daddy.” 

Samir notices the older beast and is leaking all over the ground. 

“I see him boys. Let’s go show them a good time.” 

“Absolutely Samir. Come on Gino. We are bigger and stronger than them, I guarantee it.” 

“Heh, no doubt about that Tom.” 

The three beasts finish disintegrating Samir’s house and start walking towards the other hulks. What do you think will happen now?
