They told me to stay out of the lifting area - it was safer.  Seeing all the bent metal, I had no doubt.

Sweat and spittle spattered, glistening and streaming along swollen mounds of muscle that stretched like cellophane with each lift.  Lauren's tight brown curls were stuck to traps that pushed her ears forward and flared up along the back of her skull while she spotted Sofie on the bench press.  Sofie's platinum blonde hair spilled over the sides of her wide shoulders, soft and feathery around the engorged beef of her frame. Her light, high pitched voice sounded simultaneously cute and oddly sensual with a low growl underneath it with the delicate little “mf”, “mf”, "mf", of her exertion.   

Each lift injected her meaty muscles with more vein-crossed beef, the bar already bent not just with all the dangerously clattering slabs of lead, but to make room for her freakishly enormous and continually swelling pecs.

Lauren’s own massive pecs seemed to twitch with each of Sofie's lifts, the prominent thick ribbons of her lips almost blocked by their swollen groove crossed massiveness.  Player piano ripples and divots surged melodically through her craggy slabs of flesh. The slight bend in her arm as her hands followed the weights up and down pushed the sweaty beach ball heads of her biceps almost a foot past her hands, but I knew they could get much bigger.  Oh god could they get bigger.

“That’s it Sofie, all the way down, just stop right at the top of that nipple - God I love those nipples!” Lauren popped the P, licking her lips slightly.  She wasn't wrong though - everyone with a pulse loved Sofie's nipples.  Even through the thickest fabrics, they were full and prominent, this nubbly raspberry texture visible.  The weight sank into Sofie's massive G-cup breasts, but her pectorals alone kept the bent portion of the bar almost two feet above her rib-cage - stretched steel went almost vertical as it plummeted down to her delicate hands and then thrust out to each side, teetering with outrageous weight.  Her massive body was drenched with sweat, and veins had started popping out everywhere, even her forehead.  Despite the torturous lifts, she still maintained a certain playfulness. With a sly smile Sofie jiggled her massive boobs with the bar and, winking, threw the bar up with a feminine squeak.  Her pectorals mushroomed with her upward thrust, filling up the space between her chest, arms, face, then far up above her hands, filling the two extra feet, then stretching the bar even further.  She squeezed her enormous pecs as they swelled easily five feet above her  chest - and then the bar started to squeal.

Lauren's eyes glazed: “Mmmm, Sofie look at all that muscle”.   Arching her own back in muscle lust the burly brunette buried her nose in her own pecs as the twin white rhinos on her chest squeezed her boobs up into her shoulders.  Moaning erotically she started rubbing the striations of her own pecs along Sofie's, their flesh making an odd purring sound, like someone using an old washboard as an instrument.  It was hard to believe but Lauren’s pecs were every bit as big as the chest pumping blonde (probably due to arousal).  However, they looked smaller on Lauren’s slightly taller frame.  Beneath her massive pectoral muscles Sofie’s muffled voice seemed to be moaning in equal arousal.  

Shockingly, Sofie's breasts were getting as pumped as her pecs. I didn’t think, and outside of her still don't think, most mammary glands actually have muscle - but her G cups swelled to K cups whenever she did chest work, and today they looked significantly bigger than even that.  Fuck, they were freakishly swollen, striated, and pointed at the tip - like some kind of overworked onion dome capping a Russian palace.  The gland itself seemed like it was somehow pumped to bursting on top of her pecs,  allowing her to actually rub the metal bar back and forth with her nipples without moving any other part of her body. Just lusty, muscle infused nipples getting themselves and us off with their freakish enormity. As she held the weight up, squeezing maniacally, the bar kept squealing as her breast went from soft mushy globes to mutant mounds of vein and meat, stretching the bar thinner and thinner until I was sure it would snap.  Between her double mounds of orgasm inducing mass, her spotter couldn‘t have reached her nipples if she was stretching up on her tiptoes.  If not for the fifteen foot ceilings in this gym, there would be hard nipples poking through the tenants floors above.  Instead these two girls appeared to be chest humping each other with little grunts of pleasure as the metal finally snapped. Lauren responded quickly, despite her level of arousal and caught the broken halves as Sofie’s exhausted arms fell to each side. You could barely see the upper lip of Lauren’s smile from behind her massive pectorals as she said “my turn honey“.  

She tied the two halves together as easily as you or I would handle twist ties.  

She moved to the very back of the room safely out of everyone's way, and looked me in the eye "Sofie needs protein" and immediately started doing alternating curls with the brutalized weight.

She was handling dozens of tons one arm at a time.

I moved out to the floor and approached Sofie bottle in hand and a raging hard on like you can't imagine.  Her pecs were deep red, gnarled with veins like some vine covered stone turret in a medieval painting.  Just being this close to these rippling striated masses capped with luscious tits - Jesus I thought I was going to explode. I handed her a bottle of thick protein powder. She touched my hand as she took the muscle building fluid and she started drinking, then smiled at me slyly and gestured to Lauren.

 Much deeper throated than Sofie, Lauren’s exertion was monstrously sexual, like some animal panting with lust.  Now the potential of her monstrous biceps were starting to come out.  They literally doubled in size with the first few lifts, by now her biceps were easily taller than she was, like an entire basketball player was stuffed in each arm and then tangled in a ball of fire hose veins.  It’s impossible to describe the strange compression and expansion of each lift. When her arm is straight, the bicep is still the size of  a jumbo beach ball, but somehow as they get squeezed they, well, expand in a way that doesn’t make sense with a contraction, but it pumps her veins to the size of some kind of ancient sequoia’s tree roots, and every time her arms straightens again the bicep returns to a Bigger relaxed size, and then the squeeze makes it thrust further, her fist not even quite making it to the top of the tendon connecting her bicep.  Before long Lauren’s biceps were each the size of a full sized van.

I could feel the hot dribble in my pants, the skin straining, as gentle fingers brushed against my arm. Sofie let out a heated moan, then a giggle "I wonder which one of us is going to cum first".

Lauren's voice became ragged as it became harder and harder to lift - her skin had to be screaming from the strain.  It sounded like stretched leather. You could barely see her eyes glistening from behind a wall of pectoral muscle framed by fucking fallen towers of muscle - no, geological slabs of glacial bicep muscle stretching across the room.  Lauren let out a roar - no a SCREAM as she slowly worked her forearms up one last time.

"I WILL"!!!

The air tore as her biceps erupted like meat volcanoes as muscle exploded from muscle,  twin freight trains of lust engorged power bearing down on us from across the room as her pussy spurted, blasting so hard it lifted her up off the ground.  The weights fell from her fingers, cracking floor tiles and making the ground shake.

Sofie and I jetted thick white fluid from deep in our curled toes -  asses clenched, throats dry, absolutely weeping with lust as we collapsed to our knees on pools of salty wetness.
