      NEWS: Discord Server & Clubs (aka Groups) are back!   08/19/17

      Hello everyone I'm back with a couple big updates! Firstly we now have a Discord server, this is a real-time chat messaging client you can run on your phone, desktop, or anywhere. It's a pretty powerful desktop application that enables people to chat together, and with multiple channels you can find people interested in what you're interested in. If you don't already have a Discord account it's pretty easy to get one, just click the following invite link to get started: https://discord.gg/Ahzu9jC Secondly I'm proud to announce the return of Groups, it's been renamed to Clubs and is now available here: https://muscle-growth.org/clubs/. This system is entirely user generated and allows users to create groups of their own based on any subject they want. Go ahead and try it now, visit the link above to get started if you want to create or join a group!   As always thank you to all of our donators and Patreon contributors who keep the forums going!

  2. Professor Schnackenburg's mistake

    VERY NICE! impressive! I didn't expect something like this! Thank you!! DAMN that's good! I second the cheers demanding another chapter
  3. FEEL the Growth

    God damn, had to share this! Anybody else ever feel something like this? OK, so it was a fantastic, and incredibly weird night. Had a first date at the gym, yeah met her on Tinder, was meeting up this evening at the gym and showing off the beast in action and getting to see her fantastic form…GOD I love leg day. Squats are the best. That said, fuck me..it was..wow. So we finish up, my quads so goddamned thick, so meaty and full, fighting for room in my pants with my growing hardon watching both her AND my own ass in the mirror (I’m a narcissistic beast, what can I say!) and she says to me we should hit up the massage chairs, I’ve never tried em before, but figured..why not! It’s a huge black chair that just completely engulfs me, I loved it! I’ll admit, I’ve had a VERY bad experience with a masseuse before. The guy was BRUTAL and almost dislocated my shoulder, but god damn this thing was EVERYTHING I needed. With so many settings, like Shiatsu, lower back, BODY STRETCH (THIS ONE IS IMPORTANT, remember it for later.) I just hit all the buttons and start relaxing. And it is amazing, these tiny little hands working over my thick muscled frame, the pleasant burn and ache warming and spreading as it kneads and paws my sweatsoaked frame! I won’t lie, I’m letting out little moans, it’s almost sensual! And then I feel it..subtle at first! Starting with my calves! feeling the leg rests getting tighter, pressing against my calves as the heat moves up my legs, my pants VERY VISIBLY bulging now, not just the still pulsing quads but the fucking beastcock sliding down my inseam, digging into my thigh! The chair is literally growing tighter around me! God ALL over too! My pants getting altogether FAR too tight as the material is stretched and pulled as the chair keeps seemingly shrinking around me! My ass, those glutes worked til they were on fucking FIRE, the chair is getting so TIGHT around them! My moans are getting WAY louder, my date very much noticing as I’m trying to play it off, my mind (still a bit confused from being up so early, still a bit panicking) Is racing “What is HAPPENING to me..what the..GOD the chair is getting so TIGHT this..this CANNOT be real. This CANT be happening! oh god I’m getting so FUCKING HARD this is fucking INCREDIBLE! The sensation now has moved up my back, spreading to my shoulders and neck, pulling my shirt tighter across my frame as the walls of the chair squeeze and seem to SHRINK around me! Now, I’ve been working HARD, this beast is toning up, losing the musclegut and fuck I love the leaner, more veined and ripped up beast I’m becoming, but as I’m sitting there, the chair growing tighter around my lower back it’s forcing what’s left of my musclegut UP, making it swell and STRAIN against the shirt I’m wearing, fucking tight as a drum and SO FUCKING hard just like my cock which is fit to fucking burst! "GOD no it’s GROWING again I was..SO fucking lean too! FUCK what’s..WHAT?” I’m breathing in short shallow breaths like a beast about to fucking cum, it’s FUCKING amazing. My thick arms pressing my chest up and OUT as the chair seems to be made for a fucking TODDLER now, like..if I MOVE my body’s gonna BURST out of it, send its shrapnel flying! My pecs so FULL my musclegut back at full fucking BEASTMODE and I feel as BIG as I’ve ever fucking felt! And it’s all happening HERE. on a first fucking date! TRYING to make a good first impression, thought I knocked it out of the fucking park just with the leg press alone but now..GOD not here. NOT NOW. I’m getting so fucking hard I can’t even FOCUS on what she was trying to say to me “IM SO BIG. GOD I’m so fucking BIG” staring at myself in the mirror across the gym, every part of me looking so PUMPED the veins up and down my arms and chest so BIG standing out so hard, my date is a fucking droned out wall of noise as I’m about to fucking LOSE IT! “GOD i’m IMMENSE i’m a FUCKING GIGANTIC MUSCLE GUTTED THICK COCKED HULKING FUCKING BEAST GOD!” AND THEN BEEP. the cycle of the chair ends, and the inflatable air cushions all deflate simultaneously, saving me from bursting outta my pants and making a HUGE mess. Yeah, I’d selected the Body Stretch which along with the massaging, grips your whole frame and stretches..and god damn, for that 15minute period, I was GROWING. I was literally outgrowing the chair, picturing my date impaled on a cock bigger than her little thighs swelling up through the fucking ROOF! I was UNSTOPPABLE! It was amazing and I’m ABSOLUTELY doing it again next time. Also, as a foot note, the look on her face, staring at me, body trembling, muscles pumped bigger than right after the workout, veins throbbing, face and neck bright goddamned red and a bulge you couldn’t hide with a half dozen hands. It was fantastic. No word yet on if there’s gonna be a second date though haha, she’s not replied to me at all yet.. Share your experiences too guys!
  4. Sometimes I want massive muscles. But others...

    Haha fuck man, BOTH of those fantasies are so damned hot, and I'd HAPPILY help you reach either one! Either help grow you, hulking you into the most monstrous fucking beast on earth...or give you that huge swollen pregnant gut so fucking BIG even MY arms can't wrap around it.
  5. Getting erections at the gym?

    ALL of the goddamned time. It's just..it's PRIMAL it's this realization that EVERY lift, every CURL every press I'm GROWING. slowly sure, micro tears healing over as I pound rep after rep but I'm GROWING god DAMN it's impossible not to bone up! But yeah tight boxers and loose sweatpants helps a bit, and I go late at night thanks to being an overnight worker so it's usually clear anyway, but still I give MAD props to the beasts out there who can control themselves better haha
  6. Is it possible to do it with nothing?

    haha Young, poor, but aching to GROW, and that's what matters most! Yeah, what you're describing is basically a calisthenic focused workout routine, so as mentioned above, squats https://www.youtube.com/watch?v=nEQQle9-0NA pushups https://www.youtube.com/watch?v=IODxDxX7oi4 lunges https://www.youtube.com/watch?v=BbExjzx75Hs planks https://www.youtube.com/watch?v=pSHjTRCQxIw ALL fantastic!! Sit ups, chin ups (you don't need a fancy bar, you just need a doorframe that'll hold your weight!) You've got a stair climber available if you've got any stairs in your home/apartment! That said, I wouldn't trust the ab king Pro...it seems..untrustworthy Like..dangerous ALTHOUGH the bench could work! You could use it as a decent incline bench, lean against it, and lift/curl etc. (As for weights, you're doing a great job with equipment bags filled with gear! You could also use 2L bottles filled with water!) Those are just for starts too! There's SO many options! I can't wait to hear/see about your progress! Keep GROWING man!
  7. MetaMorph Gym by Cutlerfan

    When i saw this a day ago I got SUPER excited, then realized it was just a placeholder haha, but MAN it was worth the wait! More to come in a PM obviously, but..FUCK man! OBVIOUSLY the growth is amazing and I love the pacing, but the dialogue! It feels so perfectly at home in the mouth of a GROWING BEAST it's equal parts lustful, loving and POWERFUL, as these two great beasts grow out of control with one another! Kinda makes a beast a bit whimsically hopeful for his OWN monster to grow with thanks man!! GREAT addition to the storyversary!
  8. HERE it is guys! My entry! I hope you like it! It's an Audio podcast, of a Youtube fitness blogger trying a BRAND NEW cycle! Give it a listen/Look! From GB's Instagram Midnight JUST hit, my balls are nice and empty thanks to one last cum! Let's DO this!! Can't wait to get MONSTROUS! #GB #GROWGOALS #EDGECYCLE #BEAST! From GB's Instagram See what I mean? FUCK this thing is..god I love it...I am going through WAY too many boxers like this though.... From GB's Instagram And THIS is what I get for edging while running an errand. YES I am aware shorts are not an option for me anymore but..damn I just..I love how my bulge looks in em..fuck me...Anybody got any spare pants? From GB's Instagram GOD DAMN getting ready for bed is rough...waiting for my buddy to get in here with the bungee cords to strap me in..might have to get something stronger soon!..Fuck...I can barely WALK anymore... From A Buzzfeed Article on the aftermath Youtube Fitness Star gains MASSIVE weight with new diet gone wrong? You won't BELIEVE what happens to him!
  9. Thanks for following me.

    1. GiganticBeast


      No prob! Thanks for being a great big fuckin BEAST! haha Keep on Growin man!

  10. Growing Together

    It had BETTER be continued haha this is a GREAT first story on here man, can't wait to see what happens next!! LOVE a great big musclegutted beast too fucking huge to MOVE properly! Though they could clearly use a few more..tons of muscle eh? haha
  11. "You're big enough though" I swear..if I could gain a pound of muscle every time I heard that...I'd be a walking MOUNTAIN of size. It's not so much sabotage that I've experienced thank god, but every partner I've had has voiced that to me several times. It's like...confusion on their part? like...I've already gotten "Big enough" to be a big guy, why not stop there you know? but..I just wish I could meet someone, who understands it's not a WANT on my part, but a goddamned NEED.
  12. Dating Tips

    Don't be hopeless my friend. You've got a LONG life ahead of you, and plenty of time to meet the beast you need to make your life complete! The only tips I can give? Don't knock yourself as "not worth it" to a big ol beast you'd be interested in! If you're worried about approaching beasts just join the gym and do it there! You kill two birds with one stone, you get to be in a setting where the guys are PRIMED for compliment (usually wait til they're racking up the weights/between sets haha) and you can help turn yourself into one of those very same beasts! OF course I've got a bit of a RBF (resting Beast Face) so i tend to always look SUPER angry, even though I swear I'm not, so as my face is flushed red, sweat covered and thick veins pulsing up over the top of my bald head, I don't get approached too often, even if I'd really appreciate it! So yeah, don't judge a beast by his cover, give it a shot! Something as simple as "Wow, you're looking pretty damned big lately man!" If they respond negatively, it's a random compliment, no big deal! if they are more receptive go from there! It's a pretty safe way to do it and approach the biggest of the big haha
  13. Final Boss

    DARK SOULS AND GROWING MUSCLE GIANTS!? WHY AM I SHOUTING? I CANNOT STOP! FUCK ME THIS IS INCREDIBLE! yes GOD this was AMAZING!!!! I love the concept of growing as leveling up, and..and GOD you described a dark souls NPC so fucking well I'm gonna feel bad about killing them now...but once I remember I have to so they can respawn and GROW, i'll feel better haha
  14. Fuck yeah man! That's amazing! Look, in my eyes, there's a HUGE difference between showing off, and arrogance. You can tear your shirt off in an explosive double bi flex, and let everyone around you stare in wonder at the body you've worked so fucking hard to create and that's 100% alright!! Arrogance is the sense that, because of these muscles, this size, this MASS you've earned, you're BETTER than other people around you. So long as you are avoiding that? not letting the thoughts of "GOD DAMN i'm BIG" drift into "I'm BIGGER and BETTER than everyone" you've got the beast under control and can FLEX away to your hearts content! You've earned that size, enjoy it, and keep GROWING!
  15. (NSFW) Insane cumshots !!!
