Muscle Expansion - Tumblr Posts
upping my dose today for the second time cus i need to be this big and feel a twinks hands around my arms,pecs, ass, leg thicker than his abdomen. don’t worry, he’ll be just as big soon if not bigger than me when im done making him into my muscle toy. always trying to help a buddy out,, no one will ever call him tiny again
finding your blog is the sole thing that changed me dude i NEVER had a muscle expansion kink before this just know you've ruined another one (for the better that is)
-sincerely, the anon that asked about red meat + was worshipping the muscles
happy to save another guy from the twink trap and rot his brain with muscle porn, when u start to see changes in your own body its so addicting. for me outgrowing clothes is what did it, working out normally and suddenly my shoulders completely filled out my shirts and all my workout pants were too tight on my ass, which is happening again right now. its so hot,, taking up space and everyone noticing how different you look, it makes me so hard i feel like im gonna pass out
this kink is sooooo underrated for trans men
not a feedee but bulking is something that can be so hot,, , not caring about what you eat and stuffing your face with anything you can just to hear the guys at the gym tell you they can see how hard you’re working 🥵 want 2 open my mouth and be force fed protein shakes
You came to a local diner to meet a high school buddy you hadn’t seen in years, who had already stacked plates from the lunch buffet and had been for some time, based on the collection of plates a waiter was taking away.
“Hey man!”, he greets you enthusiastically, his voice deeper than you remember. “Sorry ta start without ya bro, starting a new bulk ya know”. You can’t take your eyes off his arms that looked ready to bust a seam open in his shirt at any minute. “I don’t mind,” you say red-faced after holding your breath, “honestly, I wouldn’t have recognized you if you hadn’t greeted me”. Your buddy flexes his biceps so it smashes against his pec, before swinging his arm out and flexing his lats and bicep, opening his mouth a bit and looking like a total slut. “I know, I gained like, 100 pounds or something. It keeps packing on and I fuckin love it”.
You watch entranced as your buddy puts away enough food for an entire family and more, and each bite of food he takes seems to unlock another level of his potential. With every mouthful his muscles swell leaving you out of breath, watching the veins pop up over his arms and shoulders, seemingly getting more prominent moment by moment. His only purpose to indulge and grow into a massive muscle slut that only cares about eating, lifting, fucking, and shoving a needle in his ass.
You notice you aren’t the only one staring at your buddy’s growing body—you caught the waiter hovering, practically drooling. “Careful there, big guy,” he said, letting his hand slide down your friend’s shoulder, “you might not fit out the door if you get any bigger”.
When I say I want to be big I mean BIG big like, second picture at minimum, with way bigger pecs if I have my way.
Boy ➡️ Man
He didn’t believe I could make good on what I’d offered until he heard the sound of rubber stretching as mass poured onto his frame. His eyes got wide as he saw himself in the mirror, already huge muscles expanding like rising bread.
“Holy shit… You fucking serious?” he said, bringing two titanic arms up into a double biceps pose, pausing to fully acknowledge their new girth. “How is this even fucking possible?” he asked.
“Do you care?” I snapped as I walked a semi-circle around him, admiring my work. “One snap of my fingers and you’ll double in size. Sound good?”
He bounced two big mounds of pec beneath his cut-off. “Fuck, dude, what’s the catch?”
Walking up beside him I ran the palm of my hand up his lats, my fingers resting in his deep muscle-pits. I could see him struggling to resist the tickle. “Who said anything about catch? You wanna be the biggest dude in this state or what?”
He looked down on his widened frame and quietly moaned, “Yes, please…”
Then the real change happened. Shoulders and traps swelled, swallowing his head. Arms blew up on lats getting wider by the second. He had to adjust his stance to adjust the doubled diameter of his broadening thighs. “Fuck,” he said. Even the muscles in his face had grown, squeezing his mouth into a grimace. “I’m fucking… huge…” he said through clenched teeth. “Wonder how much I weigh?”
There, of course, was the catch, but I wasn’t about to ruin the surprise for him just yet.
“There’s a scale behind us,” I said. “Go check it out.”
It took him a full minute just to get his blimp-sized body turned around. It took even longer to get any momentum going. His new legs were so engorged with muscle he could only move a few inches at a time. “Shit… fuck... “ he said, his fingers wiggling in frustration (the only movement he could really manage).
He started building up speed about halfway across the room (long minutes later, of course). Then he took a step and suddenly lifted off the floor, floating a few feet before touching down like he’d walked on the moon. “What was that?” he said. He took another step and went even further, drifting a few inches above the ground before gently touching down again. “What’s goin’ on?” he said as the last of his new mass settled into place. He was nearly spherical now, solid bulging muscle, arms and legs out straight. Movement for the poor guy was now impossible--but that wasn’t the last change to be had. He gasped loudly as his feet suddenly lifted from the ground.
He strained to touch his toes to the floor again but they got further away. I had to surpress the urge to laugh at his expression as gentle air currents caused him to tilt, slowly rotating him until he was upside.
“If you’re curious,” I taunted, squatting down so I could be face to face with him, “you’re practically weightless, and soon to be less than that. All that mass? Full of helium. You’re now a big old muscle balloon. I collect them, you see.” Out of my gym bag I pulled out a heavy metal ball attached by chain to a collar I fit around his neck. “Can’t having you float away on me now. You’re going to love it in my garden. You’ll be my eighth bodybuilder balloon. All swaying in the wind, whimpering and moaning. Hopefully those nasty raccoons don’t get back in again with those sharp claws.”
His eyes darted around wildly and I couldn’t resist so I kissed him, knowing he couldn’t do anything but accept it. “Just like Spider-man, hunh?” I said, giving his over-muscled cheeks a gentle pat.
