Eventually after a few more minutes waiting,the bus came around the corner of the road.

It stopped with a hiss and the doors creaked open. I could see the bus was already quite full and the windows were steamed up with the heat from inside,even with most of the little slot windows opened up. I waited as the passengers before me got on..then managed to squeeze myself on before the driver refused to allow any more passengers on. I fought my way down the aisle and quickly grabbed a free seat at the back of the bus and settled down for the 15 minute journey home. The bus set off on its route,crawling slowly into the traffic. I wiped the steam off the window by my seat and peered out at the the world,trying not to oggle the cute young twentysomething guy with the backpack who had chosen the seat beside me.

He was gorgeous.!! With flirting glimpses,i furtively eyed him up. He was light olive skinned, definately a latin stud..

Fairly long messy raven black hair,a strong slim face with full thick lips,and a silver stud pierced just below his bottom lip. Lean and muscular beneath the dark green tee he wore,drawn tightly over his strongly defined chest,a hint of dark chest hair just revealing from a low neck collar.

Strong muscular arms sprinkled with dark stubbly hair..thick biceps beneath the short sleeves.

He had his backpack on his lap,but i could see he was wearing beige khaki shorts and the hint of powerful and hairy legs. Damn,i was getting a boner in my pants and shifted uncomfortably in my seat,but the smell of his manly sweat turned me on so much i could feel my cock dribbling pre-cum.

Hell, i was so un-nerved that i could suddenly smell my own sweat.!

The bus moved achingly slow as i tried my best to keep my attention out of the window.

Then the guy shifted in his seat,drawing me back to look at him. He raised his arm and brushed a hand through his hair. And i nearly came in my jeans.!

I could not avoid the sight of his bicep flexing in his sleeve,stretching the material wafer thin, a vein seemingly pulsing across the thick curved muscle. I looked away again before i lost it completely.

Then i heard a rip.. I was drawn back to the hunk. His bicep had made a tear in his sleeve.

It bulged and flexed almost as if he was teasing me,but he was looking ahead. Then i saw his bicep flex again and looked as if it was swelling. I rubbed my eyes as if i was hallucinating seeing his muscle grow. No.. His bicep bulged and expanded as if being filled by air,the vein streaked across it, thickening and rippling. Then he lowered his arm,but the bicep kept growing,and the rip split wider.

His hairy forearm thickened and rippled and his delts bunched up and filled out the shoulder of the sleeve.. 'Riiiip..!' The thin material of his sleeve could take no more and literally burst apart.

The hunk just sat there staring ahead as if this was a naturalprocess as his back thickened beneath his tee,rapidly filling it out with engorging lat muscles that pushed back against the seat and then burst the tee apart.. I found myself being pushed against the window,pinned by the studs growing muscles. His thick chest joining in the growth,the already meaty mounds expanding into huge heaving slabs that pushed outwards against the straining shirt. With a loud rip,the front tore open,freeing his growing bloating pecs,heavily covered in dark curly hair and capped with large juicy nipples that pointed ever downwards with the growth of his muscles.

Still,he seemed unperturbed by his growing muscles filling the small gap between our seat and the one in front, as if it was perfectly normal !.

My eyes shot forward as he glanced at me and smiled before looking away.

My eyes settled on the back of the guy sitting in the seat in front,and i nearly fainted!

He was wearing a denim jacket stretched across a wide back that was thickening and filling it out with swelling lats and beefing up shoulders. I watched in awe and shock as the seams on his shoulders ripped and his bulging delts poked out. The guy sitting next to him in a smart executive black suit was going through the same process.His perfectly ironed jacket was bulging and filling with a massive back that easily began to tear through the thin fabric in the centre and at the shoulder seams.

I shuddered as i felt myself cum in my briefs,and moisten the crotch,turned on and pinned in by the now huge Latin muscle hunk that filled the seat beside me.

A teenaged boy with messy blonde hair,wearing what had been his school unform stood up from the seat in front of the two hunks in front of me. He was fucking enormous,his white shirt,tie and blazer,torn and ripped to shreds over huge bloated slab like pecs smooth and glistening with sweat under the dim lights of the bus,..fat boulder like biceps rippling and streaked with chord like veins,looking perhaps 30 inches if humanly possible!. Hard brick like 8 pack abs crunching and flexing..

Oh fuck!.. i thought..shocked at the hinting sight of what could only be a huge oversized cock, the engorged base of the shaft hanging out of view behind the seat from a dense patch of sandy pubes, as thick as my forearm.!!

I shot my gaze out of the window as he glanced over at me with a hungry looking grin.

But looking out of the window was no good..

The bus stopped sharply at traffic lights..and a motorbike pulled up level with my window.

Its rider donned in thick black and red racing leather and a black helmet with its visor down hiding his face. I nearly had heart palpitations...

Even in his leather bike gear, i could see his muscles growing..!

Huge biceps bulging and straining into massive boulders. Swellling pecs pushing out the front of his

tightly buckled jacket,snapping the straps as they grew.. The cod piece covering his crotch bulging obscenely as his cock and balls grew visibly big,pressed up between his legs on a motorbike he seemed to be quickly outgrowing too.

I even thought i heard his leather groan under the pressure.

He spotted me staring at him and stuck his middle finger up before moving forward.

A white transit van advertising a builders merchants slid up next,with three occupants.

"This is too much!" i muttered under my breath.

One young guy in a blue and white Nicholson shirt and burberry cap and smoking a cigarette,was resting a tatooed arm on the van door, unbothered by the fact that his bicep was filling out and ripping the short sleeve,growing into a huge mound.. The other two occupants were growing too,but i could not see clearly. The guy smoking his cigarette,noticed me and flexed his bloating bicep.

I felt myself cum again..

The car in front..All i could see was the drivers arm sticking out the open window,thickening and ripping the shirt he wore.

I had to get off this bus.!

At the next stop, i squeezed past the huge latin hunk with great difficulty that made him complain, oblivious to the fact that he was the one blocking the space with his overgrown muscles.

It was hell trying to keep my composure brushing past the boys huge heaving pecs and seeing his huge cock hanging low and limp over engorged balls at least 12 inches, then pushing past a shaven headed muscle man in a torn England Football shirt whose own huge hairy pecs were pressed against a creaking side window, his fat heavy cock hanging low and engorged between his meaty tree trunk thighs low past his knees.

I pressed the bell urgently until the driver let me off.....and i ran home as fast as i could..to clean myself up and to take stock of the new muscle world forming around me.. •
