This is the story of a certain group of anthro alien biker mice and how they went from sexy, strong, and buff to hyper masculine and super strong with a little unintentional help from some old enemies.
His muscles flexed, bulged and swelled bigger on his frame till he went from a professional body builder’s build to something beyond when his muscle groups all doubled in size. He grunted as he looked down and could no longer see his feet over his top shelf pecs. He didn’t know it but his five-inch soft member went to a nine inch soft member that was thick as a beer can when totally unerect.
His height remained the same glorious seven feet as before but his hands and feet swelled to keep up with his power packed body. Were he wearing his gloves the meaty hands would have torn free and his massive feet made short work of the bunny slippers as they ripped out. His legs packed muscle upon muscle that threatened to rip out of his now super tight pajama bottoms.
“Whoa! Talk about a pick me up! That’s more like a pick me up up and away,” smiled Vinnie, “Now it’s time to show just what these bad boy mamma jamma muscles can really do!”
He gave a flex and his restraints ripped from the table on both his wrists and ankles. That flex shredded his pajama bottoms and left him in a pajama cloth thong that bulged so obscenely with his massive package it could hardly be said to have kept him decent.
Vinnie hopped down and noticed that the cuffs stayed on. Limburger chuckled, “Those cuffs are Monstrellian Steel, made to fit whoever they are upon no matter what size or shape they take so good luck getting out of those.”
The powerful mouse looked at the cuffs then at his reflection in the shiny metal table he tore free from. He gave a few flexes and poses then kissed his bicep, “Who needs to get out of them? I think they go well with these,” Vinnie gave a mammoth flex and then said, “Now I know I had a bodacious bod before but this is ridiculous. Mouse babe extraordinaire is gonna tail whip this place to nothing… but first how about I add a little size the way that big blue meanie used to?”
Vinnie put his thumb in his mouth and started to blow. He didn’t gain much in the way of height but as he did his muscles gained size and mass, the stone floor cracked under the weight of his massive feet as the several tons of biker mouse exploded in muscular girth. He caught his reflection and looked to Carbuncle who was scanning him with some kind of device, “Yo! Science man. What gives with the gains?”
“It a-a-a-a-appears that the serum vastly increases both mass, strength, and muscular density with every blow to the equivalent of what Gorgonzola did but with the subject remaining a more manageable height,” said Carbuncle. He put his fingers to work at the controls and started to convert the remaining monster semen into the muscle serum.
The much more muscular mouse pivoted on his feet innocent like as he watched the scientist work. Two more vials filled and only just as the monster semen was deplenished, “Whatcha think you’re doin there, sweetheart?”
“We’re making more serum and you are going to die!” said Limburger as he pulled a machine gun out from behind him. He unloaded on the massive mouse and at first Vinnie put up his arms, only to find he was bullet proof. The mouse chuckled and thrust his chest forward then started to walk towards the Plutarkian. Limburger panicked as the footfalls shook the ground and cracked the floor under the biker mouse’s muscle weight.
Vinnie blew into his thumb more and his muscles swelled even larger still. The remnants of his pajama thong fluttered to the ground as his now foot and a half long soft cock with massive balls ripped free. Limburger saw this as a point of vulnerability and fired his tommy gun at that massive package but the bullets bounced off it all the same. However, it did start to arouse the tremendous mouse.
His height reached eight feet tall as the plutarkian stopped firing then said, “Uhmmmm heh. Look my good Mr. Van Wham perhaps I was a bit brazen in trying to fire a gun at you like that but can’t we simply talk this out?”
Vinnie kept walking up as the Plutarkian backed up, “There is a time for talk and a time for action… and speaking of action…” he looked down at the three foot long colossal pillar of mouse flesh that jut forth from his crotch as a monument of mouse cock, “I might need to get some action to get this baby to go back to sleep.”
“Duh I’ll give ya a little action biker mousey!” Greasepit shouted as he ran up to Vinnie.
Vinnie stopped and held up a hand as the massive and greasy muscle man charged him. He flicked the man with his pointer finger to the chest and knocked him through several walls at incredible speed in the process, “Whoops! Heheh guess I don’t know my own strength.”
“Carbunkle! Do something!” Limburger shouted as he ran for the elevators. His scientist rushed to the elevator as well and the pair got stuck in the door side by side.
The massive mouse looked over the pair then to the machine that could make more muscle juice. He saw the two vials then walked over, shattering stone under his powerful bare feet. He took the two vials that remained and held them gently in one hand while with his other hand he brought down a fist on the machine. That downward punch sent the machine through the floor, and several floors down, causing it to explode. The building shook but held together.
“I don’t think I’ll ever get tired of that,” Vinnie said with a playful bouncing of his gargantuan pecs. The mouse watched as Carbuncle and Limburger made their escape in the elevator up and he shrugged, “Looks like it’s time to blow this popsicle stand,” He walked up to a wall and then through it like it were made of tissue paper. He did this several times over until he found the wall that lead to outside. He looked down and was apparently on the 50th story of the 100-story tall building that was Limburger Tower. He grinned and hopped out casually, cratering the floor even with that small gesture.
Vinnie relished the feeling of the air blowing over his massive naked body, clothed only by the metal cuffs that Limburger was so kind as to provide. He hit the ground with a crash that cratered out from his eight-foot hyper muscled frame it flipped over several vacant and nearby cars and left him standing in a literal crater in the street fifty feet across and twenty feet deep. He set down the vials of muscle formula and carefully covered them with rubble for protection, “Be right back my little beauties.”
The tremendous, naked, bulging, fully erect mouse climbed from the crater of his own making and then walked up to Limburger Tower while stroking his throbbing three-foot pillar of mouse cock. “Time to rock Limburger’s world in a way he never thought possible.”
Vinnie blew into his thumb and kept blowing, swelling bigger and bigger, his muscle grown larger and stronger, more density added with each blow. His cock engorged till it was five feet long with beach balls for testes that swung behind impossibly muscled legs on his now nine foot muscled mouse frame, “Oh ho ho yeah! Let’s do this!”
The mouse went up to the side wall of the tower and thrust his invincible column of mouse cock into the side. He gave a powerful flex then lifted the entire building off it’s foundation by his cock strength alone. “Oh baby where have you been all my life?”
The biker mouse dug his beefy fingers into the wall of that building and held it up with ease as he started thrusting in and out of the building, quaking the few left inside and even the ground around him. His feet sank down up to the knees but the Plutarkians had replaced the building so often that they made the foundation he stood upon quite impervious to most damage, hence why he didn’t sink into the ground instead of lifting off the building.
The mouse neither knew about that nor cared as his precum exploded out with the strength of a dozen broken fire hydrants as he pained the lobby and started to fill the first floor up. Feeling the fluids splash and the building’s stone mash against powerful dick drove Vinnie wild. It wasn’t long before his balls began to swell and the ground trembled with the force he was about to unleash.
Vinnie moaned, “Three…” then thrust again and groaned, “Two,” then pounded his hips to the building again, “One” and it was just one final thrust when his cock swelled and he felt the seed jet down it saying, “Blast off!”
His massive cock exploded with millions of times the potency it should have been able to where he a normal Martian mouse, which would have only been a few dozen times more than the normal human, but now he unleashed a torrent of white hot cum from his titanic cock that exploded up through the floors of that hundred story building as he filled it. His eruption filled all one hundred floors of that building with cum spurting from every window and exit door before the mouse let go and his second shot rocketed the building off like a literal rocket into orbit. He held his cock and kept spurting a rain of cum that drizzled down over Chi Town for a good twenty minutes. Better than the normal acid rain most would say.
His muscles deflated to how he looked shortly after his initial injection which still left him far stronger than ever before by several dozen times. However, he was still naked except for the metal cuffs on his wrists and ankles.
He walked up to the cars he’d accidentally flipped on his descent from the tower then flipped them back casually. The hood popped off of the last one and he took it in hand then looked to his nakedness and his foot long flaccid cock. He blushed a bit then stepped on the middle of the hood then pulled it up around him, ripping out the middle and then folded it down over his legs and his swinging junk to make a makeshift metal kilt for his own decency.
The mouse went back to where he stashed the muscle serums and recovered them then started the walk back home as the sun started to rise on Chicago, “Man my bros are gonna love getting huge like me. But we’re gonna need Charlie to help modify the bikes for a little added weight… among other endowments. I wonder how I’ll find pants now… or boots… oh well…”
Vinnie chuckled to himself as he playfully flexed his newfound super muscles the whole walk home.
