All subjects included in this story are of age and there will not be any issues associated with each character. Brody has always loved his dad. Growing up, he looked up to his dad because he learned a lot about life from him. It wasn’t always easy getting any attention from him, considering that Brody had five other brothers to contend with as well. His dad, whom they called Branch, always seemed like he was living life to the fullest when he was younger. His wife, Beverly, had to put up with a lot of shenanigans from him, which was passed on to a couple of Brody’s brothers. He sometimes encouraged them to get out there and experience things on their own when they were teenagers. Brody was always the introverted one though. He just wasn’t interested in all of the typical horny teenager stuff. He wouldn’t realize that his dad noticed this until he was older. By the time all six of his boys were adults, Branch was in his 50s. He was reasonably built when he was younger, but he was never what you would consider a muscular type. He admitted that he did play baseball and run track when he was in high school. A conversation came up one day at one of the family picnics about why Branch decided to have so many kids, and they happened to be all boys. He jokingly said, “I guess I am just that potent!” Which resonated with Brody more than he thought it would. Branch did notice his son’s reaction to his statement and it was like he knew that he had a gay son. It was a secret that he thought he had kept from his dad his entire life. A couple of years into college, Brody came to visit his dad at the home he grew up in. He was surprised to see that his mom was not living there anymore. It turned out that their marriage had been falling apart for years, but they stayed together for the boys. Once the boys were grown, Branch and Beverly felt like they didn’t need to stay together anymore and separated. The 53-year-old man is alone at the house with just Brody, which rarely happened. He tells his son to sit down so they can talk about some ‘important’ things. “Have a seat, my boy. Well, I should say, my man.” “Uhh, what is this about, dad?” “Well, I just wanted to let you know about some things that I have kept to myself for some time.” Brody seems a bit confused with where this conversation is going. “Umm, okay. Does this have to do with you and mom?” Branch smiles. “Actually, it does. Your mother and I decided a few months ago that we needed some time apart. *Pauses for a few moments* Well, hmm. This is actually a bit more awkward than I realized. Brody...do you remember when you use to have your friend Reese over on your spring and summer breaks a year ago? *a few beads of sweat drip down Branch’s forehead* Well, we kind of did a few things together.” Brody’s eyes widen. He is stunned by what he is hearing. “WAIT...WHAT!? You mean, ‘those’ things?” Branch seems a bit nervous, but understands why Brody would feel this way about the situation. “It really does depend on what you mean by ‘those’ things, Brody. I am implying that I spent some time exploring his body. I don’t know the last time you saw Reese, but he has changed dramatically over the past year.” Brody admits that he hasn’t seen Reese in nearly eight months because the 20-year-old man left the university they went to because he wanted to pursue a career in emergency services. In other words, he wanted to be an EMT. “I am just trying to grasp the idea that you are interested in men, dad. Have you always had an interest in them?” “Well, just a little bit. I did enjoy raising you boys like normal fathers do. I know you probably felt a bit left out at times because I spent a great deal of time with them. I always knew I would have the opportunity to play catch up with you when you got older. Well, here we are.” Brody calms down a bit. He sits down a few feet from his dad on the couch. “So...is Reese in town now? Are you admitting to me that you are gay? I mean, you had six boys by mom.” “No, I consider myself bi, Brody. I enjoyed my time with your mom, but I feel like that ship has sailed. Reese has helped me explore one of my deep-rooted fantasies. I should call him actually.” Branch gets his phone out and tries to call Reese. He answers after the second ring. “Hello there, Mr. Agassi. How may I pleasure you today?” The middle-aged man blushes and quickly says, “Shh, Brody is here with me.” Reese chuckles a little before saying, “Do you want me to come over before I go to work?” “That would be a good idea, stud.” Reese says, “Okay,” and then hangs up. Brody barely recognizes Reese’s voice. It is considerably deeper than he remembers. “His voice is so different now. What gives?” “I don’t know son. I just know that he is helping me understand who I am. He should be here shortly because he only lives about 20 minutes from here.” After randomly talking about Brody’s brothers for a few minutes, there is a couple of knocks on the front door and a man walks in. He is absolutely massive. He has a well-kempt beard, perfectly parted black hair, the tightest uniform you could imagine, overtop of mammoth garden-hosed veins on what might be 22” biceps and triceps that are so big, they can’t be contained. His chest bulges out of any crevice that might be available. His quads are stretching his pants to their limits. He walks up to Branch and Brody and stands in front of them. “Hello bro and boss. Glad to see you are both here at the same time.” He sits beside Brody and puts his arm around him. He slowly flexes his right bicep to make his friend feel it digging into his side. “Uhh, what happened in the last year to lead to this, Reese? I am blown away by your ‘transformation’.” Reese smiles and decides to tell his story. He grins at Branch because he can see the man’s thick tool swelling his pants. “I left college, but you already knew this Brody. When I started my training to become an EMT, something unusual happened during one of the training exercises. I was accidentally electrocuted by the paddles they use to revive patients. *Sighs a little feeling his bicep accidentally tear his right sleeve* I was taking gear at the time, which I don’t know if you know, but it is supposed to help you grow your muscles. You remember what I looked like; well, I sort of had an unexpected growth spurt that led to an unfortunate wardrobe malfunction a few minutes later. I mean, I loved it, but it was a bit awkward for the people that were training me.” Brody looks over and sees his dad rubbing his cock inside his pants. It is apparent now that his dad has a strong muscle fetish. Reese moves his arm away from Brody and flexes it, making his biceps and triceps swell huge. The tension on the sleeve is way too much as the raging muscles rip their way free from his undershirt and jacket. He does the same with his left arm. “Umm, wow! Well, it appears that whatever happened during that training exercise was a huge benefit to you.” “BRO! You have no idea...well maybe you do. I mean...*pauses for a few moments as he continues to flex* I have a fetish of my own that I want to explore. Well, first I want to tell you Brody that I have had a hardon for your dad for years. He is fucking hot! Last year, when he even gave me an ounce of suggestion, I went for it. Anyway, I want to have a threesome with both of you. I think this could get really interesting if we do it.” Brody is shocked at this suggestion, but Branch seems extremely open to it. He pulls his pants down and shows that he is going commando. It is the first time that Brody has ever seen his dad’s immense tool in all of its glory. The throbbing 10-inch pole pulses wildly dribbling a small amount of precum down the front of it. It turns out that he is uncut as well, but he has the sheath pulled down to let it breathe. Reese gets up and walks over to Branch. His breathing is slightly heavier and is getting a bit excited. “You see how hung your dad is, Brody? I have wanted that inside me for years. We haven’t actually gotten to that point yet, but I think now would be the perfect time.” Reese undoes his belt and unzips his pants. They drop to the ground and unveil his bloated lower body, which is covered in a vast network of veins and black body hair. He is wearing a jock strap which contains a nicely-sized package. He walks over and lets Branch smell him. The older man strokes himself a few times before stopping and letting his cock bounce, it dribbles a bit more precum. Reese makes sure that Brody watches them. “Just watch us for a few minutes bro. We mostly did this type of worship, but I am done with it. I think maybe I can convince him to go further this time. *Stares into Branch’s eyes* You want to taste me, boss?” Branch looks up at him before pulling the young beast into his face and starts licking Reese’s bulge. They both moan. The excitement is enough to prompt an accidental hulkout to happen with the EMT’s shirt and jacket as his pumped back explodes out of the fabric. He decides to go ahead and just do the same with his entire top as he flexes his chest and lets the buttons cascade all over the room. He then rips everything off and lets his furry powerful chest reveal itself. Branch pulls Reese’s jock off and gulps down on his cock. Brody is mesmerized by what he is seeing. He should be horrified to see his dad doing this, but watching this is too hot for words. Reese grunts and flexes his chest and arms as he gets his cock worshipped. He looks over at Brody and motions for him to come over to them. “Come here bro, I want to share this experience with you. Your dad is fulfilling one of his fantasies, will you fulfill one of mine?” The college student is beginning to figure out what he is insinuating. “You are absolutely insane Reese. I have never wanted to do that with my dad, ever. I mean, I admit it is amazing looking but...” “Just imagine that he is another incredibly attractive man with a big tool, Brody. Besides, your dad has mentioned before that he wouldn’t have ever minded if you wanted to come and play with him.” Brody’s curiosity begins to rummage through his brain now. There were instances when he wondered if his dad could produce even more children than he did. It was a weird thought he had at one point or another. Why would he ever want to find out how potent his dad was? Did his dad give him hints? He thinks that maybe he did. Now would be the time for him to find out. As Branch continues to milk Reese’s cock with his mouth and worship his hairy body with his hands, Brody does move over to them and touches his father’s cock for the first time, feeling its thick veiny sheath and bulbous purple head. He is shocked to see how big his dad’s balls are. He cups them in his hands, which gets a huge sigh from his dad. He stops sucking Reese for a minute. “Do it son, worship my cock. I have discussed this with the hot stud here. You have always been my favorite, I just wanted to save this experience for when it was appropriate. Well, this is clearly a great time for it.” The smell emanating from Branch’s crotch is intoxicating. Brody’s judgment is being clouded by the hormones being pumped into his brain from his dad. He starts to kiss his dad’s balls and slowly laps up the sticky goo at the base of his dad’s shaft. Branch moans deeply, realizing what his son is doing. Reese is watching eagerly as well. The beastly EMT motions for Branch to focus more on his upper body than his cock because he thinks he will cum without being milked. “Ohh fuck Brody, you are actually doing it. Gawd, this is fucking hot. I want you to make your dad cum. I can only imagine how amazing it will be.” Brody is now consumed by the need to satisfy his dad’s throbbing tool. He runs his tongue up and down the shaft, making his dad tremble and watches Branch’s balls flexing. Reese floats the idea to let his dad penetrate him, but the college student says no. Reese says he will do it then, but not until he blows his load onto Branch. It turns out that Brody’s dad is quite amazing at being edged because he is able to withstand multiple attempts by his son to make him cum. “Hold on Brody, let me join you. There is no way he can handle two hungry mouths.” Reese gets down on his knees and takes turns with Brody gulping on Branch’s cock and licking his soaked cockhead. The older man is almost in his own world, concentrating on keeping it from happening. He will finally lose the battle as he feels the flood leaving his balls. The two young men can sense it and await their reward. Branch gasps and yells in delight as the cum sprays Brody and Reese in their faces. The EMT shoves Brody’s dad’s cock down his friend’s throat and lets him savor it. “Shit...shit...fuck it is so hot watching you do this. I am about to cum myself Brody. Watch me shower your dad with my load.” Reese barely gets to his feet before his cock begins pumping jet after jet onto Branch’s sweat-soaked shirt and legs. The young beast’s cock, albeit not as impressive as the middle-aged man’s, is still very meaty. He produces a great load himself, as it continues to coat the eager recipient. Brody is able to drink the entirety of his dad’s flood as he pulls it out of his mouth and kisses it lovingly before sitting it onto his dad’s-stained shirt. Brody’s cock pulses wildly in his pants, filling his underwear with a puddle of sticky goo itself. It is at this point that Reese and Brody can hear Branch making some rather unusual grunting noises. They both notice that the EMT’s cum has completely vanished. Did Reece’s cum get absorbed into the older man? It turns out that it did, and it is about to transform the mildly-athletic middle-aged dad into a huge hunky beast. Branch’s excitement is very clear as his cock rises quickly, expanding slightly bigger, as the veins expand and his ballsac swells even bigger. He can feel his feet and hands swelling as the growth slowly moves through his body. He flexes his forearms, watching them expand and twitch, growing thicker and meatier, the fur thickening and the veins pulsing and growing just beneath the skin. His upper arm follows with bulging veins popping out everywhere, the biceps, triceps, and delts expanding quickly, testing the limits of his shirt, before finally emerging within seconds. Both arms are covered with a thick layer of black fur, covering massive mounds of powerful flesh. With Brody in between his legs, he is able to feel his dad’s quads, hamstrings, and calves stretching bigger and meatier along his sides. The fur thickening to cover mammoth tree trunks and oversized mounds of power, that would be classified as calves. He reaches in to feel his dad's glutes ballooning along his hands. His dad once used to say that he had no ass, but that doesn’t seem to be a problem any longer as he can feel them pushing him up into the air. He moans as the growth moves into his chest. His traps rip through the top part of his shirt as his neck expands to twice its size, veins flaring and exposing what is forming beneath it. Chest heaving wildly, the outline of Branch’s swelling pecs is obvious. Thick, wide, pumped mounds of pleasure try desperately to rip free from their confines. Branch’s back will not wait as his lats burst out of the sides, and continue growing. Reese and Brody can hear the beast’s shirt ripping in multiple spots along the back as ripples of thick mountainous muscularity appear out of what seems like nothing. His immense pectorals are pushing his shirt out nearly two to three feet in front of his face, exposing his beautifully formed adonis belt, thick eight-pack of abdominal bliss, and the rapidly-growing obliques that are merging with his incredibly-dense latissimus dorsi. He finally reaches in to slowly rip the rest of his shirt open, revealing what the two young men were eager to see, two bloated, nicely-coated with black fur, incredibly veiny, swollen, rippling, pumped pectorals, with perfectly shaped nipples pointing downward towards his abdominal cavity, that any pro bodybuilder would aspire to achieve. He is also no longer clean-shaven, sporting a newly-sprouted beard, full of a mixture of black, red, and silvery threads of thick and silky hair. It slowly descends down his chin and onto to his immense pec shelf. His eye color has even changed ever so slightly to a hue of bluish-green. The hair that was receding on his scalp, has all but vanished, leaving a shiny, sweat-soaked, and very muscular face and head. He now looks and feels considerably younger and more virile than he could have ever dreamed of. He is insanely handsome as well. He feels the adrenaline flowing through him as he reaches down to run his powerful hands along his son’s face. He smiles at him. “Hello my boy. In case you didn’t know, I have had a longing for this my entire life. Not necessarily the part where you may have consumed some of your dad’s cum, but the part where I may have become like Jay Cutler.” He lifts his son up off the floor and sits him beside him. He then reaches over to shove Reese on top of his now 12x10 inch cock. The EMT groans feeling it stretching his hole, trying to accommodate the now enormous tool. The 20-year-old slowly starts bouncing on top of Branch, flopping pecs, sweat dripping and all, and making grunting noises as the two men try to focus on getting a rhythm going between the them. Brody’s dad looks at his son through what seems to be a different lens now, seemingly more interested in wanting to turn him into what him and Reese are. “Brody... *Branch’s voice noticeably more masculine and remarkably intoxicating* I really want to turn you into a version of me. It would make me the happiest father in the universe. *Continues to grind Reese* Mmm, your old man has never lost his touch with any hole he has entered. *Laughs* I wonder if my cum will make this beast grow again?” He picks up his rhythm and gets up from the couch, holding Reese up with his massive 24” guns, flexing them, making his hairy triceps bulge and swell, showing off his strength. Brody gets a full-view of his massive father’s enormous, bulbous backside, from his bloated glutes, to his valleys and canyons of muscular superiority in his back and hamstrings. He thrusts, making the EMT moan loudly, as Branch turns to say something to Brody. “Come over here son and feel your dad’s muscles. I want you to get acquainted with what you could have. You have the gene to achieve this. I think we are past the point of where this might be a problem. If you want to have some fun with me, don’t be ashamed to pursue it. I love you for who you are, and I will help you out in more ways than one.” Brody briefly questions his dad’s proposition, but realizes how he has never been this turned on ever in his life before. His dad’s transformation into a Roelly Winklaar/Jay Cutler type of musclebeast is something that might have been in the recesses of his mind once before. His cock has spilled so much precum, that it is running down his right leg now. He gets up from the couch and presses himself up against his dad’s gorgeous back. He puts his arms around his dad’s sides, past his flaring lats, and places his hands onto Branch’s swollen pecs. He then slowly kisses his dad’s twitching back muscles and deltoids, which gets a deeply-rooted moan from Branch. The musclebeast is seriously turned on that his son is behind him, and is exploring his body. “Do whatever your heart and mind wants to do Brody. It is built into both of us. I am so grateful that this hot little beast that I am fucking was given the gift to transform me into the beautiful gawd that I was always meant to be.” Feeling his balls swelling with cum, he grunts and groans trying to will them to drain. Reese, loving the fact that Branch is a massive daddy, punches him several times in the abs, making the musclebeast sigh as he feels his cock swelling inside the EMT. It won’t be long now. “Watch your maker unload inside your friend, son.” Branch moans and groans as he stops thrusting and pushes his cumload deep inside Reese. The young beast yells loudly feeling it flow into his intestines. He rubs his huge chest and pecs as it passes through his body. He is barely conscious, as the whole situation is nearly too much for the EMT to take. He is blown away by the experience. Branch motions for Brody to stop what he is doing for a few moments so he can pull out of Reese and lay him on the couch behind them. He then picks up his son in his arms and takes him into his bedroom. He gets into the bed, still carrying him, and lays him on top of his gigantic torso. “Brody...I want you to worship me. Don’t hold back, let your inhibitions roam. *Looks down at Brody’s stain-soaked pants and rips them open. Brody moans* Yes...I know how much you need this. *Starts coating his son’s cock with his own precum and lightly strokes it with his huge hand* Look at me, Brody. *They lock eyes* I love you, son. Reese made me into this, but now, I want to give you my gift of growth.” Branch pulls his son up to his handsome face and kisses him on the lips. There is no resistance at all anymore. Brody pulls his pants down as his dad rips his shirt off of him with one of his hands. The young college student is running his hands up and down his dad’s mammoth forearms and biceps. He rubs his cock up and down Branch’s huge abs as they massage it, kneading its sides. “Play with my chest, Brody.” Without hesitation, the young man runs his tongue and lips along the contours of his dad’s bloated pectorals, chewing on Branch’s nipples and feeling their raging power along his face. He can feel his dad playing with his ass now, placing two fingers inside his wet hole, which are nearly the size of a cock themselves. Brody is humping his fingers now, which gets a major reaction out of Branch. His dad’s cock rises into the air and spits a few droplets of precum onto his son’s back. “Mmm, you are getting your dad incredibly excited Brody. Don’t stop doing what you are doing. Keep exploring me. I promise this will last for a while.” The young man can feel himself getting close to exploding as his beastly dad manages to push two of his fingers all the way in to massage his son. They lock eyes again as Brody tries to muster a few words. “I...uhh...I love you dad. I know this is wrong, but it feels so right.” “It is perfectly alright, my man. Let it all out, let your dad see what you are making in there.” Brody gasps as he starts cumming all over his dad’s abs and pecs. Branch grunts and smiles seeing his son blast his incredible body with his cum. He holds his fingers in place, feeling his son twitching as his prostate undulates against his dad’s fingers. It is one of the most satisfying feelings that Branch has felt with anyone. His cock throbs and swells, eager to find its way into another longing passage. They kiss each other, like any two masculine men would, with deep moans and groans. Branch laughs feeling his son play with the long mane on his chin. He flexes his massive arms up against Brody’s body and slowly starts to push him down towards his cock. “You know what time it is, son. Time for your awakening. I want us to savor this for as long as we both can. *Realizes that he wants to be fully appreciated* Wait, why don’t you explore your dad’s other huge muscles.” He has Brody get up off the bed, while he stands up as well. His cock bounces a few times as the young man immediately starts to massage his dad’s incredibly huge tree trunk quads. He flexes them as Brody kisses the inside of both of them. His dad’s pole rubs itself all over his face as the college student starts playing with his dad’s thick sheath and gulps down his cockhead. Branch moans deeply and tells him to do that again. “Ohh shit, Brody. That feels so good that...doing that again might do something even greater.” The second time the young man runs his tongue along the thick shaft and head, he is greeted with a thick, gooey, jet of precum that is dangerously close to being pure cum. He drinks it down his throat and feels a lot of tingling travel through his body. He is in a state of disorientation, but likes the feeling. His dad sighs and laughs knowing that things will get interesting very soon. “Uhh dad, that felt strangely satisfying. I feel compelled to keep doing that.” “Hold on Brody. Why don’t you move yourself up to my face for a few minutes so I can examine you. I want to see how much your old man has passed on to you. Wait, let me sit down while you stand in front of me.” The young man does what he says as Branch smiles staring at the impressive equipment that his son has. It turns out that Brody does have a decently sized cock with a nice set of balls. His dad rubs his uncut shaft against his sweaty beard as the two men moan deeply. Branch’s son dribbles a few drops of precum onto his dad’s mane, which makes the older beast let out a few “mmms”. He then looks up at his son while leaning in to slowly suck on both of Brody’s testicles, massaging them equally. The young man trembles in delight, as his beastly father holds him up with one of his immense arms. Branch is worshipping his son’s package, running his tongue along his son’s sheath, feeling it throbbing wildly against his muscular face, and letting the precum continue to drip. “Let’s see what you taste like son.” Branch slowly pulls his son’s sheath back with his lips, revealing his big cockhead, as he slowly lets it invade his mouth. He is methodical and laughs as he does so, seeing Brody’s reaction. He knows his son will probably unleash his boys pretty soon because he is so turned on. The massive beast lets out a few gulping sounds when he starts to get a rhythm going, but then picks up speed when his mouth gets used to accommodating Brody’s beauty. “Ohh fuck dad, I can’t hold it back much longer...I feel like I am going to explode...” Branch gives him the thumbs up with his free hand as he continues to work his son over. Brody yells as his balls contract and pushes his load into his engorged shaft. His dad chokes as some of it goes rolling down his thick beard and onto his bloated chest. He keeps his focus though and keeps draining his son, gulping down his cum and smiling. He takes his free hand and grips his son’s pole, stroking it. After about thirty seconds, Branch pulls his son’s cock out of his mouth and lets a few more strands of cum roll down the shaft, licking it lovingly. He kisses Brody’s cockhead. “You did take after me, Brody. I always wondered what that tasted like. *Knows what needs to happen next* If that is any indicator, I have a feeling that you will grow big like me as well, my boy.” The college student seems a bit anxious about growing into a muscle monster, but the thought of being bigger than his brothers does have its benefits. “I would have never considered this before now dad, but I love the thought of being bigger than...” Before he could even get his sentence out, Branch grabs his son with both arms and places him on the bed, turning him around to bend him over. He quickly plugs his eager beast into his son’s wet hole and starts pounding him. Brody groans for a few minutes as his dad grunts, wanting to convert his son into what he is. He stops thrusting to let his precum invade his partner’s insides and feel him tremble against his quads. “This is going to be fucking great Brody. I want to experience your changes at the same time that you do.” Not long after he says this, Branch pumps his son full of cum. The force is enough to make Brody yell nervously, but they both laugh soon afterwards. His dad pulls out of him as they both drop down onto the bed together. The bed breaks, but they don’t move. The thickly-muscled man holds his son against him and awaits his transformation. He can hear Brody groan. “Ohh, it works fast. I suppose that is because it is immediately absorbed into you, my man.” “I can feel it dad. It feels really weird, it surprisingly doesn’t hurt either. I think I am feeling my cock and balls reacting...” Branch lets his son move over beside him on the broken bed as his son’s cock begins to slowly stretch longer and wider. It throbs as he feels his ballsac doing the same, as his testicles double in size, filling in every ounce of space in there. His dad lightly rubs Brody’s growing package, and feels its raging power in one of his thick paws. He then leans over and nuzzles his son with his facial hair on his boy’s face. “I am anxious to see how far this goes Brody. What is next?” The young man moans feeling his ass swelling, pushing him up a few inches off the bedsheets. It is stimulating him to the point that he is leaking precum onto his chest. Branch takes his free hand and glides it underneath his son’s wet glutes and finds his pulsing hole. He massages it slowly, not penetrating him as to distract from his concentration. “Let me help you along buddy.” Branch stops stroking and massaging Brody and moves himself down to his son’s lower half, looking up at his anguished beast-in-waiting, and smiles as he starts to kiss and suck on the young man’s mammoth tool. He moves his hands up and down his growing beast’s legs as they start to expand, seeing his son’s quads hug his immense crotch, filling in the space that used to be between them. Veins pulsing and throbbing, growing bigger and more massive on each tree trunk. Branch’s cock is now throbbing, feeling his young beast’s calves growing against his giant chest and his toes getting thicker with each passing second. The fur thickens on both legs, with a golden-brown tint to them both. The same goes for his crotch, as Brody’s thick and veiny 13-inch rod coats his dad’s beard in a thick gooey layer of precum, after Branch promptly works him over. Branch pants voraciously, sweating profusely feeling his son transform against him. He is about to unload without even touching himself. “I love you son. This is what you are doing to me right now.” The older beast humps his cock on Brody’s thick ankles and feet, and sprays them with his colossal load. He moans deeply as he kisses his son’s bloated quads and runs his soaked beard on both of them, mixing their fur together. It is another fetish that he is not afraid to show. He awaits his son’s transformation on his top half. He can see how much the young man is struggling with his breathing. “Let’s see it happen Brody. I want to feel it happen.” Branch hears his son let out a few odd noises as he moves his immense furry body up in time to feel the young man’s chest starting to react. He tenses up as his abdominal cavity begin to grow rapidly, the obliques and lats practically appear out of nowhere. The older beast grunts and moans loudly, running his hands over top of his son’s emerging eight-pack, which appear in a zig-zag pattern. They are quite dense, veins scattered about. The same golden-brown fur grows overtop of them. He kisses each one and runs his tongue along the deep caverns forming between them, making his son shutter and shake a bit. He gets sprayed by his son’s meaty pole, which delights him, knowing that Brody is fully into it now. “I knew you were like me boy. You just needed someone to help you along.” Brody’s lean pectorals are next to transform, as his moaning turns to yelling, feeling both of them stretching, growing, thickening, several inches higher than they were just seconds before. Branch gets so turned on by this that he sits up really fast to smack his cock on his son’s bloated tits. “YES! FUCKING YES! I can’t get enough Brody...” He blasts both of his son’s gigantic chesticles with his cum, as they are covered with the same coating of golden-brown fur as the rest of his body. The young man no longer looks boyish either, growing a beard, and looking a bit older. His back’s growing mountains and caverns of sheer power are assaulting the bed beneath him, as the bed breaks down even further. He looks directly into his dad’s eyes and starts flexing his arms as they begin their metamorphosis. His cock bounces wildly as he says, “Keep watching dad...KEEP WATCHING!” There are sounds cascading through both of Brody’s arms, as his forearms, triceps, and biceps start exploding in size. His veins swelling cause his arms to shake violently, as Branch reaches in to hold both of them in his hands, helping his son out. “YEAH BOY! Grow big and beautiful like me, I love it! Let the alpha take over.” He positions himself on top of his son’s gargantuan cock and slides Brody inside him. He starts kissing each one of the young beast’s expanding guns, feeling each one of them blow up against his mouth and lips. He can hear his son quietly saying to himself, “more...more...more”, as he realizes that he is imploring his arms to keep growing, and they do. Brody’s forearms are actually fighting with his biceps for positioning as his dad keeps licking them, feeling the veins mate with his mouth. He is bouncing on his mammoth son now, shaking the entire room. “FUCK ME BRODY! Even if we don’t do this ever again, I want you to make your dad feel proud of what he has done for you.” “Dad...*voice incredibly deep now* I am so happy that you did this to me. I love you so much.” “I love you too, my beautiful boy.” Brody finally stops flexing to let his mammoth arms have a rest before his dad leans in to kiss his son on the lips. The two bearded beasts moan and grunt as they wrap their huge arms around each other and proceed to fulfill what they have both wanted, at least for the last hour or two. Lots of cum is unloaded inside and spilled onto each other. They eventually wear each other out and fall asleep. When they wake up, they have trouble getting up off the ground, due to their immense sizes. The two hulking, hairy beauties decide to take turns in the shower, and avoid each other, at least for the time being. Brody is curious to know how big his arms are, so he manages to find a tape measure that Reese left in the family room. He wraps it around one of his arms, and stands in front of a mirror. Looking at himself for the first time, since the change, astounds him. He is more beautiful than he ever imagined. He didn’t realize that he lost the hair on his head through the change, but his beard is quite similar to his dads, only mostly made up of golden-brown hair. He grunts looking at himself, flexing his arm and watches as the tape measure struggles. His left bicep eclipses 26” which stuns him, as he drops the tape measure on the floor. His dad comes up behind him in a towel and hugs him tightly. They look at each other in the reflection and smile. “You just got yourself dirty again, dad.” “I don’t fucking care boy. I just love looking at the two of us. We are both so hot. Go get your shower.” Brody leaves as Branch looks at himself in the mirror. He takes his towel off and watches himself get hard again. He flexes his chest and arms and decides that he might as well just get off again. He is quickly greeted by his son again, who decides to do the same. They press their chests together and laugh, feeling their balls fill up with cum again. The two muscular behemoths realize that they have forgotten about the third man in this scenario at that very moment. “Dad, what happened to Reese? *Laughs a bit* We could have included him in this whole fantasy.” “You’re right Brody. He probably had to go to work. His job is a very important one after all. It is okay, my hunky man. He will be quite shocked the next time he sees you.” They both smile and go back to worshipping each other once again, staring into the floor-length mirror and pumping each other up, flexing and feeling each other’s individual muscle groups once again. While it might be taboo to love your father in this way, Brody can’t imagine things ever being the same again with him. Branch would promise his beastly son that they would keep their sexual fantasies from the rest of the family. It would not be easy to explain Brody’s rather large ascent into muscular godhood. His brothers, who were the center of attention for so many years with their father, would not believe anything that he told them about his new interest in bodybuilding. Their relationship with Branch would become quite strained, seeing that he also had changed physically. Perhaps it was a bit of jealousy on their part? (This was a bit strange though, considering that two of them, who also have the growth gene, became quite big and burly themselves. Only they didn’t get cut and veiny.) The family picnics still happened, but you didn’t see the brothers hanging out with their dad and hulking brother anymore. As for the hunky EMT, he did wake up, dazed and confused that day, and waddled to his truck, completely naked. Incredibly, he left just minutes before Brody went through his tremendous metamorphosis. The strange accident that materialized into Reese’s growth cycle, ended up triggering the extra growth gene that was lying dormant inside of his daddy lover, and ultimately his friend. Reese will indeed get his chance to see the beautiful 20-year-old beast in his new, mind-boggling form, but that is another day.

Please God not now, I am not prepared for this.’ Sam grips the sides of his bathroom sink as he stares into the vanity mirror and grimaces. ‘Ack! It hurts, it hurts…. damnit!’ He feels his back trying to pop as he struggles to maintain his composure. He attempts to keep his voice down so his dad doesn’t hear him, but unfortunately it doesn’t work as he hears someone’s footsteps coming up to the door. They knock a few times. ‘Sam…. son I’m sorry you are going through this buddy. I wouldn’t wish this on anyone trust me. Just try to keep as calm as possible and you might be able to ride it out without too much of a problem.’ Fortunately, the 20-year-old college-aged young man is only wearing his boxer briefs as he feels his muscles starting to tense up and grow on his slender frame. He anguishes in pain feeling his back giving in to the change. The small bulbous muscles in his arms stretch and swell against his skin as the pressure he is putting on the sink causes it to start cracking. He then moans as he feels the changes affecting his nether regions. ‘Sam? Buddy fight it…. (Senses his son’s changes through the door as he feels a bit strange himself). Uh shit…. (Sweat starts to pour down his own face and down his lean chest). Talk to me Sam…. let me know how you are doing.’ Sam’s dad Dale knows he can’t stick around long himself because he too will be thrown into a major transformation of his own. The sound of porcelain hitting the floor behind the door tells Dale that Sam is giving up on trying to fight it anymore. ‘DAD? *His voice noticeably lower now* I think the bathroom is going to have to be remodeled again. Oh…. damn…. *Sounds noticeably pleased* it feels so good this time though.’ Dale rubs his beard slowly and tries to keep his composure. He knows that keeping calm can help contain the man from within himself from coming out and going after Sam. ‘Okay Sam…. just please don’t make too much of a mess.’ The growing teenager feels his legs pushing his boxer briefs higher on his quads as they stretch wider and harder. His calves have now doubled in size as his height begins to increase. His 5’9 frame is now stretching to over 6’2. He moans louder as his pecs balloon outward making his nipples tingle and his crotch react. He rubs his chest as his abs pop out and create a perfect 8 pack. He massages each individual slab and lets out a few deep sighs. Hearing his son’s moans, Dale begins to struggle with his own problem as he feels a twinge inside his stomach. He grimaces grabbing his chest and feeling the sweat increase as it coats his tank top and shorts. ‘Sam…. I won’t be able to help you much longer buddy. You know who is going to want to have a few things to say to you.’ Sam continues to grow as his ass stretches his boxer briefs to their limits as his cock snakes its way out the bottom and pools precum on the floor as his back and lats stretch even wider. He reaches up to feel his face firming up as his massive biceps flex and push his arms further away from his face. He opens his eyes and notices they have changed color from green to brown and he has grown a beard. He reaches down to rip his boxer briefs off freeing up his ass to reach its full potential. ‘MMM damn, *rubs his huge ass* I look so fucking good dad. *Realizes in his mind that his dad may in fact have the same problem* Oh fuck, dad I hope you can keep from letting go. I don’t want what’s his face to show himself anytime soon.’ Feeling the hormones raging inside him though, he can’t help but to reach over and lift the toilet off the ground. He moans staring in the mirror at the muscles twitching as he holds it above his head. He drops it beside him shattering it into pieces and sending water everywhere. The water cascades down his naked gargantuan body making his cock swing erratically as it swells, stretching bigger and longer than before. The young behemoth growls feeling his balls growing from inside his sack as it aches from beneath his huge shaft. He checks out nearly every square inch of his body marveling at all the new bumps and crevices. He tries to keep his voice down to a minimum, but his immensely deep baritone can be heard through the door as his dad continues to move further away from the bathroom door. Dale’s body tenses slightly as he reaches for one of the posts on the front of Sam’s bed. His breathing deepens as he tries to get a few words out. ‘Sam…. son…. I don’t know if you…. can hear me buddy…. I can’t hold him back…. any longer…. (Takes his glasses off and throws them out of the bedroom)’ A loud pop comes from Dale’s back as he falls to the ground and lays his hands by his sides. He tries to control the pace of his breathing as he feels something rising from within him. He then sits up and knows that it won’t be long now. ‘Oh shit…. he really wants out tonight…. *Knows this could be a bad thing* *yells at Sam* I’M SORRY SAM…. SHIT BUDDY HE IS…. RAGING! AHH!’ Dale’s transformation is violent as he feels his muscles growing rapidly starting in his back and chest. Within seconds his tank top rips completely off starting with his back as it splits in the middle and continues all over. His chest explodes in size as his pecs inflate all the way up to his neck. Thick patches of brown fur spread across his chest covering most of the muscle. His nipples follow as they double in size and situate themselves in both corners. His mind changes gears as he laughs feeling his shorts rip open along the seams. The popping increases exponentially as every muscle in his back doubles up on themselves making his body stretch even wider. His lats push his arms further away from his chest. He feels himself getting taller too as his spine cracks and reforms adding more muscle to accommodate the added height. He tries to stand up as his immense quads and calves flex helping him lift himself of the ground. He roars in delight feeling his cock burst through his underwear and over to one side of his leg. The only clothing that remains on his body now is the waistband from his shorts which he is now staring down at. ‘FUCKING DESTROY THAT FABRIC, MUSCLE…. I WANT TO FEEL A COMPLETE FUCKING RELEASE!’ The behemoth’s ass swells bigger as he feels his muscly sides starting to stretch the waistband to its limits. He moans feeling his cock aching and bouncing relentlessly wanting complete freedom from its confines. After feeling himself growing a few more inches in height, his body finally succeeds at ripping the waistband off his pelvic region glistening with a nice brown forest and a river of sweat. The man’s massive rod throbs wildly as his balls make stretching sounds filling in every space in his sack. He looks at his biceps and sees the baseball-sized muscles throbbing but seems very dissatisfied. ‘Come on body, I know you can do better than this. Give me more size damnit, I want to feel like a god!’ The huge muscleman strains making both arms flex harder making the veins press up against the surface of the skin. He grimaces feeling huge pains passing through both arms. After a few seconds, the pain turns to pleasure as deep laughter comes barreling from his lips. His biceps begin swelling again as he watches them both grow to twice their size. His forearms and shoulders follow suit as the veins widen all the way up and down the rest of both arms. ‘YES! OH, FUCK YES! This feels so fucking amazing. *Takes several deep breaths* I haven’t been out of this prison for such a long time, I was beginning to wonder how this felt.’ It appears that the man’s transformation is complete. The formerly slender middle-aged man that inhabited this body is now absent as the man from within transformed it into a 6’4 350-pound behemoth. The man finds Sam’s mirror behind him and stands in front of it. He rubs the thick fur coating his immense chest and legs but won’t touch his cock. The 14-inch rod appears to be close to bursting and quickly turns to walk towards Sam’s bathroom door. There is silence from within the bathroom as it appears that Sam was listening to the whole sequence commence. The man stops a few feet back to speak. ‘Sammy…. open the door man. I need your help with something. Your daddy Dallas will treat you like a king if you come and fix it.’ Sam knows this will not be turn out well if he doesn’t find a way out. This isn’t the first time he has dealt with his dad’s most aggressive personality. His solution he thinks is to break down the door to throw Dallas off and just bash his way out the back of the house. When he tries to attempt this, Dallas punches his arm through the door and gets stuck trying to grab Sam by the neck. The younger behemoth manages to knock him down after the door goes flying off its hinges. Dallas growls as he lies on the ground. The excitement though makes his cock spill a few drops of precum on to his stomach. ‘SAMMY! DAMNIT, I LIKE CHALLENGES BUT THIS ONE IS GOING TO BE A DIFFICULT ONE TO DEAL WITH!’ The older hulk hears a huge crash in the other room as he jumps to his feet and rushes in there. He sees broken glass on the floor as one of the French doors to the backyard lies in a pile of rubble. Dallas seems uninterested in the damage caused and walks over top of it before rushing out the opening in the doorway and into the field behind the house. He sees Sam trying to put some distance between them. He stops at the edge of the field to yell at the younger stud. ‘COME ON SAM! I WON’T HURT YOU MAN! I JUST WANT TO FUCKING FILL YOU UP WITH MY LOVE! *Laughs loudly in his gravelly voice*’ When Sam goes to turn around, he falls dangerously close to the cliff located at the other end of the field. His sheer size is hard to control as he feels himself starting to slide over the edge. A giant hairy arm comes out of nowhere and grabs Sam’s right bicep. It of course is Dallas who has a very frightened look on his face. ‘Sammy…..don’t move man. Don’t move. Why are you running from me? I may not be Dale, but I do love you so much son.’ Sam tries not to panic as he feels his sweaty muscles twitching against his dad’s big hand. ‘Come on, let me lift you up here so we can finally let this happen, okay?’ Sam knows that Dallas will not remain in control for the rest of his dad’s life, but he wonders how long he will be around this time. He also knows that he must let Dallas save him or he will be toast. Within the next ten seconds, the huge hulk grabs Sam’s other arm and quickly lifts him up and places him back on to safe ground. Sam tries to get away from him, but Dallas grabs a hold of his arms and pulls him closer to him. The hulk’s huge rod continues to throb and leak gobs of pre everywhere. ‘NO! NO! Please God no! Dallas, I can’t take it…. you will permanently hurt me if you do this.’ Dallas moans hearing Sam’s cries as his cock shoots several ropes of cum all over his massive back. ‘UGH, Sammy stop struggling, you are just making me want it more. Just relax and let me fuck you.’ Dallas slides him underneath his body and slaps his immense rod on to Sam’s ass a few times before teasing his son’s hole with his cockhead. He pushes the head inside which makes Sam calm down a bit. ‘NO……No……no…. uhhhh…. *Feels his own cock jumping*……why Dallas…. you are my dad…. i shouldn’t like this….’ Dallas pulls it back out and turns Sam over to look him straight in the eyes. ‘We are a part of each other man, I know you will grow to love being with me someday. In a few years, you will even want your big daddy Dallas to be around forever. *Notices Sam’s own cock pulsing* Here I think you need some servicing of your own….’ Dallas lays him on the grass and leans down to start sucking on the 230-pound young man’s cock. Sam groans feeling his body shutter as he grips the ground beside him. His hulking dad rubs his son’s chest and arms and starts to run his tongue up past Sam’s abs, chest, and finally his mouth where he locks lips with him. Sam moans as Dallas lies on top of him and wraps his huge guns underneath the scared man’s body. ‘Stop it, Dallas. My dad will know this happened when he returns.’ ‘Will he? You forget Sammy, you are not yourself either. You may not remember everything either. Come on man, relax for me, please. *Lifts Sam’s legs up over his shoulders* Let your REAL daddy love you like you should be loved.’ Dallas starts to push his cock inside Sam which makes the young adult cry out in pain. Dallas slowly moves in and out of Sam pushing a little further inside each time. Sam can feel his body starting to loosen up now allowing Dallas to take over fully. ‘Good boy…. daddy Dallas will make you feel more satisfied than you ever thought possible.’ The hulking behemoth starts to pound him harder as he moves Sam’s legs around his back and holds him in his arms firmly. The son at this point just holds on feeling Dallas getting closer to exploding. ‘MMM Sammy…. here it comes man.’ Dallas grips him as he feels his cock pumping wildly inside the young man. Sam realizes this might be dangerous and starts to grow agitated. ‘NO Dallas NO! You will kill me, why? Oh god no, I can’t handle this.’ ‘Shhh…. relax Sam…. your body will recover. Don’t worry…. i won’t hurt you. *Feels his balls contracting* UHH YEAH…. OH, SHIT MAN…. OH SHIT…. FUCKKKKK!’ Dallas thrusts all his might into Sam’s hole as he launches massive rivers of cum into his son’s belly and beyond. Sam feels his insides swelling as his stomach stretches against his abs making them look more like a roidgut. This makes Dallas growl loudly. ‘OH, FUCKING YEAH…. I knew you could handle it man. *Rubs Sam’s huge gut and leans down to lick each bloated ab*’ He continues to thrust inside Sam holding him close as he looks up to plunge his tongue down his son’s throat. Sam is about half conscious at this point as he lets his aggressive dad have his way. The huge behemoth finishes cumming and stops kissing his son so he can rub Sam’s back for a few minutes. He peers down and sees his son’s cock leaking more than it did before. At this point, he pulls his own cock out of the man’s hole to move him a little further up. ‘Sammy? Son, I think you need to cum boy. Your cock is going to explode if you don’t do anything soon.’ Sam comes back to his senses and tries to free himself from Dallas again. The hulking brute makes sure he can’t get away by holding him down. ‘No Sam, this must be done. Trust me it will feel so much better when you just let it go.’ Dallas puts his arms underneath his son and lifts his crotch up to the hulk’s waiting lips. He slowly swallows the swollen rod and works it over with slow steady gulps making the young man writhe in ecstasy. Dallas tastes the river of precum flowing into his belly and knows it won’t take much to release the floodgates, so he just gulps the whole shaft down without a second thought. Sam digs his hands into his father’s legs as he pumps Dallas’s body full of thick goo. The young adult can hear his father swallowing what must be a gallon of cum and notices the behemoth sigh with pleasure as he does it. The sweat is pouring profusely from both men as they both sense that something else is about to happen. Sam finishes cumming and goes completely limp in his father’s arms. Dallas lovingly works his son’s cock a few more times in his mouth before it retreats back into its slumber. He kisses the cockhead after it leaves his mouth and picks Sam up in his arms. He kisses the young man on the lips one last time before lying down on the ground. The college-aged youngster can feel Dallas starting to doze off and manages to finally get free from his confines. Unfortunately, Sam is unable to stand up after the unreal pounding he just experienced by the huge hulk. He starts crawling away from Dallas and occasionally turns to see if the behemoth wakes up. Before he gets to the other side of the field, he realizes that he is shrinking as he feels his thick muscles starting to disappear and revert back to their original size. His ridiculously stretched hole manages to repair itself as well which gives him a sense of relief as he tries to stand up again. Once he gets back up to his feet again, he looks down the field and can see that his father Dale has returned to his original self as well and is still lying on the ground sleeping peacefully. The sun is now starting to set as the ordeal appears to be over….at least for now it is.

All subjects included in this story are of age and there will not be any issues associated with each character. Do you remember Brody? Well...he has adjusted to his new life as a hulking, hairy, hirsute hunk of meat. His relationship with his father, Branch, has never been stronger since his massive transformation. It was life changing after all. His five brothers didn’t really interact with him much for quite a while, well, at least that was the case with the two really thick ones, Benjamin and Braeden. They were the brawny ones for so long that they didn’t want to give up their titles to Brody, who was once seen as the scrawny, bookworm type. Brody has retained a bit of his intelligence after his hulkification. He tested this theory when he set up a night of trivia with two of his other brothers, Brandon and Blaine. The remaining brother, Bryce, hasn’t really spoke to him in quite some time. In fact, he hasn’t really spoke to any of his brothers lately. Anyway, back to trivia night. The two brothers that Brody has been trying to repair his relationship with did agree to spend an evening with him without their wives. Brandon, or rather Bran as Brody calls him, is a huskier version of what their dad looked like, well, when he was younger, you know, before the dramatic physical transformation. He was the football player in the family, which meant that he would get Branch to throw the football back and forth with him growing up. He earned a scholarship to play in college as a linebacker, which he was proud of. Blaine is thin, but extremely good-looking. He was the brother that lived in the same room with Brody growing up, until he left to pursue his dream of modeling. The others have always kidded him about his need for vanity, but it did lead to him meeting a lot of women and getting married at an early age. He has been married for several years to a woman named Vanessa, who is a model herself. Getting the three brothers together wasn’t easy of course, but somehow, Brody managed to do it. “Okay, I get it Brody. You are smarter than me, so what? You don’t have to prove that your brain is bigger than your biceps. We gathered this information after the first family picnic.” Blaine halfway jokes with Brody about his constant showing off. He takes note every time the massive beast gets a question right, and flexes his huge cannons, making his shirt strain and his pecs and nipples visible. Brandon quietly watches them banter back and forth, trying not to show very much interest into what Brody is doing. “I’m not trying to prove I’m smarter than you Blaine, I just am.” He winks at him. “Whatever bro...what...ever...” Blaine, who is sitting in a folding chair out on the deck of the family’s summer home with the other two, acts like he is going to get up to leave, but Brody stops him. “Heh, hold on buddy. You know I am just toying with you.” He then notices that Brandon is sort of looking off into the distance at the river. “Bran, you seem a bit out of it. Things alright with you?” Brandon snaps out of his trance for a moment. “Yeah, you two always have this tension. I didn’t want to be a part of it. Frankly, I would rather be down on the river bank just relaxing.” Brody gets that impression from his body language. “Alright, well maybe we can continue this game another time then.” “Thanks Brody. If you would both excuse me, I would like to just take a few minutes to let my mind wander.” Brandon gets up from his chair and goes down a set of stairs to the river bank. There is a couple of seats down there. The two brothers, Brody and Blaine, watch him as he goes to sit in one of them. “Brody, I am going to go order the food, I’m sure you will want about ten pounds of protein in your portion, am I right?” The hairy beast laughs and lightly punches Blaine in the shoulder. “You have learned, haven’t you? I will pay you back, you know.” “Sure, you will.” Blaine goes into the house while Brody waddles his way down the stairs towards Brandon. He might have an agenda on his mind. He walks up behind his beefy brother and puts his hands on Brandon’s arms, slowing rubbing them. The older brother is startled, but seems reasonably calm at the same time. “Damn Brody, you could have really hurt me just now, and I wouldn’t have had a chance to defend myself. Thanks for not killing me.” “Heh, I’m not going to hurt you Bran. Unless you want me to fight you, you know, in a different way.” Brandon turns to look up at him and seems unsure about where this is going. He accidentally brushes his left arm against the massive beast’s bulge and feels it twitch. It is the first time that his brother has noticed how big it is. “Seriously Brody, how the hell did you get this huge? You are freaking big everywhere. I mean...I do envy you a little bit.” Brody smiles down at him and acts like he is going to pull down his pants. Brandon stops him though. “Whoa buddy. I wasn’t suggesting that I needed to see it in full view.” Once again, the hulking beast slowly pulls down his pants and slowly reveals his insanely thick adonis belt, adorned with a tremendous forest of golden-brown fur. His mammoth tool throbs beneath the fabric of his swimming trunks. Brandon unintentionally stares at it in awe. Brody smiles and grabs his brother’s left hand and places it on his crotch. “Don’t worry Bran, I know you like my body. I have caught you looking at it more than once. We can have some personal time here together right now. I doubt that Blaine will be back for a bit, you know?” He pulls his trunks off and lets his cock bounce and leak beside Brandon’s face. He then flexes his immense glutes at the same time. His stunned brother grasps Brody’s ballsac and smells his intoxicating scent. He lightly moans, seeing the beast’s cockhead dripping precum beside him. “This is wrong on so many levels Brody. I often wondered what your relationship with dad was like because you two seemed different after you both took up bodybuilding. The thing is though...you are right. I have looked at your body a lot. It might be a bit of jealousy. I mean...I think I look okay.” He watches Brody’s shaft flexing as he talks. The sheath barely covers the beast from within it. Brandon continues to hold his brother's testicles in his left hand and feels them conform to him. His immense beastly brother breathes heavily, trying not to show too much interest in what Bran is doing with him. He doesn’t want to spook his beefy brother too much, but he is thoroughly enjoying this. “Have you ever wanted to have a body like mine, Bran? Here is your chance to join the club. I am more than ready to help you out, if you are willing?” Brandon can’t seem to concentrate on what is being said to him because Brody’s scent is clouding his judgement. All he seems to be focusing on now is the giant shaft leaking beside him. His mammoth brother knows this as well. “Go ahead Bran, let me fulfill your destiny. Make me cum inside you and I will change your world forever.” Brandon hesitates. “Wait...uh...fuck I am married. I can’t...I mean...” “Bran, I am your brother. We can keep this to ourselves.” Brody reaches down and presses his beastly cock against Brandon’s mouth. It doesn’t take much for the husky man to open up to allow the shaft to enter his face. He slowly massages it back and forth with his mouth and tongue making Brody moan loudly. The beast’s enormously hairy body is drenched with sweat, his shirt peeled to his massive upper half. His nipples protruding and hard as bricks. He is now teasing them with his fingers. “Yes Bran, oh fucking yes. This is what I have been wanting to do with you, for quite a while. You have always been the understanding one.” Brandon is now consumed with his brother’s immense rod and gets up to shove his chair out of the way so he can get on his knees to worship his brother appropriately. He makes loud sucking sounds as Brody slowly slides his tool in and out of Brandon’s mouth. While he isn’t entirely into the whole cock worshiping aspect of his brother, Bran does start to run his hands up and down his beastly sibling’s legs, rubbing his engorged quads, hamstrings, and calves. The husky one is now worshiping his brother’s cock, pulling it out of his mouth, stroking it, watching it curve upward, listening to his brother breathe heavily as he watching a stream of precum flow freely down the shaft. After a few minutes of this, Brody lets out a loud roar and tears his shirt off, revealing his mammoth upper body, heaving pecs, gorgeously thick abs, and pumped biceps and forearms. He is thoroughly excited and ready for his brother to join him into hulkdom. “Do it Bran, I am not going to hold back. I want to feed you so badly; you have no idea.” Instead of trying to put the mammoth rod back into his mouth because it has swelled even bigger, Brandon is now slowly stroking it, each time Brody gasps. “Fuck yeah brother. Just keep doing that, I think you will really like what will happen in...ahh...” It starts squirting jizz at this point. Brandon lets it coat his face after the first two strokes. The third time he lets it flow down his throat, which he enjoys incredibly. Brody is tempted to just shove his brother’s mouth over top of his beast, but he knows it won’t take a great deal of his boys to do what he wants them to do. “Savor it brother. Let it flow through you. Ben and Brae don’t know what is coming to them when we go to our next picnic. It was nice when it was just me and dad, but having you join us on this journey is going to be extra special...” Brandon continues stroking him, watching Brody’s cum increase in volume as he grunts louder, his cock slit parting wider, as it begins to fill his insides in a larger capacity. He feels a bit sick, which his mammoth brother notices. He motions for him to move away as he reaches down to continue jerking off. He moans deeply as he continues to shoot cum off to the side of the riverbank. His husky brother is lying down on the ground now. Brody finishes cumming and gets down on his knees to help his brother out. He puts his huge manly paws on Brandon’s stomach and rubs it. They have a quiet moment together. It looks like Bran is going to throw up, but Brody tries to stop him from doing so. “Hold on, it will pass, hopefully. This is the part that I am unsure about though. How long will it take before it kicks in.” He directs Brandon’s attention to the river. “Just look out there Bran. You like the river a lot, don’t you?” The disoriented brother attempts to get up now, with the help of his beastly sibling. They walk towards the water when Brandon gets a crazy look on his face. Brody knows what is about to happen. He can feel his brother’s body starting to heat up against his own. He has him up against him, which is starting to excite him once again. His cock begins to harden and rises upward as Brandon starts to groan. The husky one is starting to transform as his feet swell against the ground and his calves reveal themselves from beneath the fat that was containing them. They stop walking once they get to the edge of the river as the growth moves up into Brandon’s quads and hamstrings. Brody lets go of his brother and begins to massage the expanding beast’s bloated glutes, with his hands, which are starting to spill out of the bottom of his sibling’s shorts. Knowing that Brandon is now getting lost in his cycle, Brody is going to take advantage of the situation. His brother's shorts are now ripping at the seams, and they start to struggle down his engorged lower half. His briefs are barely hanging on, as his cock begins to expand, swelling and growing larger and thicker, his sheath is doing the same, trying to keep up with the transformation at hand. Brody tears his shorts and briefs off letting everything commence from down there without reservation. Brandon moans feeling his balls swelling to twice their original size as they quickly fill up with what will likely be a very memorable load soon. His mammoth brother knows that in just a few minutes, Brandon will be ready for him. He strokes his own tool without hesitation now with his left hand while running his right hand along his brother’s growing cock, feeling it stretching towards the ground. The husky one is feeling the surge of power racing through his upper half now. Seeing Bran’s growth commencing on his chest and back is making Brody lose his own mind. “YES Bran! I am loving this so much. Turn into the massive beast you were always meant to be.” The growing hulk, who already had a slight pec shelf after years of training for football, is feeling his pecs moving closer to his face. Each one bounces as inch after inch expands further outward from his chest, making the sports jersey that he is wearing beg for mercy. His delts and traps are protruding wherever they can get free space, as his lats don’t waste any time blowing up, tearing seams along his sides. He involuntarily starts flexing his back, something he often did when he deadlifted years ago, showing his horned-up brother that he is becoming a hulk like him. He arms quickly fill out as well, the expanding muscularity drifts downward from his mammoth delts into his swelling biceps and triceps, which are twitching and agonizing, as they hulk out. He is loving this, feeling his cock dripping as his biceps emerge from their previously hidden confines. The cords of muscle and veins expand to the point that you would no longer think he was ever husky at all. He flexes his forearms, watching them become engorged with raging power and expand to match the rest of his massive arm. His fingers and hands swell and thicken as well. It isn’t long before his pecs become too much for his jersey and spill out the sides. He grunts and flexes them. His body is also now covered in the same reddish-brown fur as Brody’s is. He can feel his face becoming more defined as he also notices that he has developed a thick mane along his face. He is loving it very much. He can feel his brother stroking his cock and turns to look at him. “No Brody...I don’t want you to stroke me. I want you to get me off the right way. I don’t even have to tell you what I am implying.” Brody doesn’t waste another moment as he gets down on his huge knees and begins massaging his brother’s cock with his tongue. It is something that he has always wanted to do, but Brandon would have never let him do it, before that night. “Yes bro...yeah bro...ohh fuck yeah bro...keep going...do it...fuck yeah...Fuck, why does this feel like I have been reborn, Brody. *wonders if he can hulkout of his jersey by flexing hard enough* Fuck, I need to do this...I MUST DO THIS! RRAAWWRR!!!” Brandon pumps himself up, pecs bloated, arms engorged, and back primed. Incredibly, the growing beast succeeds at tearing his jersey off, just by sheer determination as his furry pecs and hairy back make hasty work of the fabric as it hangs aimlessly in the wind. It is the first time that his midsection is revealed. The gut that he previously sported is long gone as a remarkably uneven set of six abdominal slabs, decently coated in drenched fur, is uncovered. Brody moans loudly seeing his brother’s entire body now completely unsheathed. He can tell how much his beastly sibling needed this. “Oh my gawd Bran, you are so fucking beautiful. Now, let’s help finish this off with a release you will never forget.” Brody stops stroking himself and runs his hands and fingers up and down his beastly brother’s new chest and arms. He tells him to flex both biceps, which Brandon immediately does. He stares in delight at them both, watching them rise, bigger and bigger, but then makes Brody stop sucking him. “Get up Brody. I have a new game to play with you. Want to try it?” His stunned brother does get up off the ground. They stand directly in front of each other, furry muscle glistening in the night air, and smiling into each other’s glowing eyes. “Oh fuck Bran, what do you have in mind?” “Who can cum first just by out flexing each other? Just a few seconds ago, when I destroyed this jersey, I felt a jolt rush through my cock. It felt exhilarating. I was only able to hold it in because you distracted me down there. What do you say?” Brody is ready for this game. “You are my favorite brother, Bran. There is no doubt about that now.” The two bloated beasts, who are remarkably about the same height, are now pressed up against each other, rubbing chests and cocks together. The game is definitely on as they both flex their mammoth guns, each one trying to figure out how big the other is. It is clear to Brandon that Brody might be just a tad bigger than him all over, but he doesn’t care. They are having a moment in time in which they might be in love with each other, and Bran can feel his load building quickly. They continue to stare into each other’s eyes and embrace, holding each other tightly, kissing each other on the lips for a brief time, before finally separating. “Brody...I love ya man. This might be one of the only times I will let you do this, so get down there and swallow my cum you hot beast.” Brody barely manages to hunker down in time before the hot flood begins to envelope his sweat-stained chest. He is able to shove Brandon’s 11-incher down his throat and let it work its magic. He sighs and holds his hulking brother against him. The satisfied former husky one standing rubs his bro’s buzzed head and finishes cumming inside him before pulling out and standing him back up. He puts his right arm around Brody’s giant delts and traps and holds him against him. He inquires about something else. “What happens if you cum inside me again, Brody? I don’t really think I want to go bigger at this point in time, but maybe later?” “I don’t know Bran. I have never tested that theory before. We will have to try it out sometime.” “I know you need to cum again, so let me see you flex your guts out. No cheating with those beastly guns you have either. I was able to do it, so let’s see you blast off too.” Brody grins as he attempts to sike himself up. He gets a few pointers from Brandon as the two men get into a heated worship session. The formerly husky one figures out that his brother loves for his muscles to be punched, so he starts to do this. The river of precum starts flowing freely after a few seconds of doing this. By the time Brody is shooting his seed once again on to the riverbank, they are unaware that someone else in the distance has been watching a bit of what has been transpiring in front of them. That someone that has witnessed this situation isn’t too hard to figure out. The thing is, how will things progress from here? How far is Brandon willing to go with Brody?
