The Worms - Part 2

She was at the gym when she realized it. She was doing preacher curls, excited at moving up to the 25lb weights, which she could not have imagined lifting just three or four weeks ago. As she powered up the weight for the fifth time, grunting and pleasurable pain at the sight of her bicep straining, she felt it.

It was a wriggling sensation in her bicep. She was startled and dropped the weight. She squeezed her bicep, wondering what had happened. Then she saw it. A slight bulging just beneath the skin. 

Teresa’s eyes went wide. Holy shit. The parasite!

Then she felt another sensation, in her other bicep this time. There was another one there, too. Oh shit, they had multiplied, just like Delia had said!

She should be repulsed that a parasite had infested her muscles. But Teresa didn’t feel that. Instead, she felt excitement. She knew what these little worms could do. She smiled a big, shit-eating grin, then looked at the mirror and went into a double-bicep flex.

Two small but well-defined biceps, about the size of small lemons, rose from her arms. As she watched, a small blue vein crested each one, a testament to how hard she had been pushing herself lately. She grit her teeth and strained, and then she felt it again. A small wriggling sensation in both biceps. She watched as a tiny bulge throbbed slowly in each bicep.

“Yes, little wormy babies, do your magic!” she said to herself. As she held the flex, her biceps vibrated and glistened with sweat, and she could almost swear she saw them bulge just slightly bigger. She squealed with glee and released her flex.

Just then, Sandra walked over and chuckled. “Not bad for definition, but you’ve still got matchsticks compared to these pythons!” 

Then she reached for the 40lb dumbells and started doing hammer curls. “Oh yeah, bitch, I moved up the weight again. I’m always growing!” she said with a grin. Teresa couldn’t help but lust after the angular bulges of Sandra’s big biceps. She wanted - no, she needed - some big muscles of her own. 

She looked down at her own biceps. She thought, “I need more.”

That night, Teresa snuck into the lab again. As she looked into the glass enclosure, she noticed that there were quite a few worms wriggling around in that brown liquid. If she grabbed a few more, surely Delia wouldn’t notice. 

As she stared at the tank, Teresa felt a slight tingle in her pussy at the thought of what these little creatures could do to her. She looked down at her biceps. “Ok my wormy babies, you’re about to get reinforcements!” she said. She felt a slight squirming in her biceps, almost as if her own little worms were anticipating this as much as she.

Must be her imagination, she thought. But who cares. Teresa reached into the enclosure and grabbed and handful of the little worms. Then she spread them across her chest and watched in fascination as they began to burrow into her skin. She felt the same pleasure as before, only this time multiplied by ten. It felt good, really good, and she almost orgasmed on the spot.

“Yesss…” Teresa sighed. “Time to get to work, little babies, and make me bigger!”

The next day, Teresa felt euphoric at the gym. She was at the bench press pushing 175lbs, an amount she couldn’t hope to bench just a day ago. She racked the weight and stood. When she looked in the mirror, her pussy spasmed at the sight.

The deep v-neck of her tank top revealed two well-defined pec muscles beneath her b-cup breasts. She flexed her right pec and watched it bunch up and lift her breast. She released it and flexed the left, watching it bunch up with grooves of sinew to lift her left breast. She smiled madly and flexed them both, watching her small tits bounce up and down on the blocky muscular wall of her chest.

“Not bad,” Sandra said as she walked by. “Looks like you’ve been hitting the weights hard lately.”

Teresa scowled at Sandra, who wore a tight sports bra that showed off her dense bodybuilder physique. 

“Still not quite there yet though,” Sandra said as she flexed a side chest pose. Her pecs bloated out, jutting over an inch from her sternum in rippled, cabled relief. Her pecs looked amazing, like two solid plates of muscle and not a hint of breast tissue. They wouldn’t have looked out of place on a middleweight male bodybuilder.

“That’s a good warm up weight,” Sandra said, releasing the flex. “But let me show you what a real woman can do.”

Then she slammed 50 more pounds onto the bar, bringing the total to 225 lbs. She laid down and hefted the bar. Then she slowly brought it down to her chest, grunted, and pushed. The bar came up as Sandra exhaled. Then she took a deep breath, and powered out another rep. Then another, and another, until she had completed a set of eight.

Sandra stood and flexed, watching her own pecs bunch up and ripple as veins puffed up under the skin.

“That’s how a real woman does it,” Sandra said haughtily. 

Teresa glared at her. Almost involuntarily, she flexed her pecs and felt multiple squirmy tingles. She let out a wry smile. She suddenly knew that she could do more thanks to her little babies.

She laid down at the bench and pushed at the bar.

“Now don’t hurt yourself there, little girl,” Sandra said with a chuckle. “That’s not the kind of weight that skinny bitches like you should try to lift.”

Teresa grit her teeth. Her anger seething, she pushed with all her might. Her pecs started burning, then tingling. Suddenly, the bar started to move. As it came off the rack, the bar fell quickly to Teresa’s chest.

Sandra came and leaned over, ready to hoist the weight off Teresa’s chest. “Told you, skinny bitch, this is just too much for you.”

“Hands off you dumb bitch!” Teresa seethed through clenched teeth.

“Fine, have it your way,” Sandra said and crossed her arms with a smug smile.

Teresa huffed and puffed and pushed for all she was worth. Her pecs burned, but then she felt a squirmy tingling, and she knew her babies were doing their job. Suddenly she felt a surge of energy. She heaved, and the bar started moving upward, slowly.

Sandra’s mouth dropped as she saw the weight move. There’s no way that skinny bitch should be able to lift this much. Then she saw Teresa’s chest. Holy shit, it was twitching with bulging striations, almost as if it was growing right before her eyes.

Before she could register what was happening, Sandra saw the bar rise up, and then fall back down again. Teresa was smiling now, a big, maniacal smile, as she grunted and powered the weight up again. And again. And again! She finally racked the weight after nine reps, one more than Sandra had done.

Teresa stood and put her hands on her hips. “What’s wrong, Sandra? Can’t handle what a real musclehead can do?”

Then Teresa grit her teeth and flexed her pecs for all she was worth. She felt them tingle and bulge as her babies squirmed and fed more growth hormone into her surging pecs. They bunched up and pushed her b-cup tits down and out, revealing muscular cleavage with thick grooves and notches.

Sandra was shocked watching this little girl’s chest practically grow right before her eyes.

“Who’s the skinny bitch now, you dumb cunt!” Teresa said.

Sandra’s face darked. She took a step forward. “Nobody calls me that!”

Then Teresa pushed Sandra with one hand, causing her to stumble backward. “I do. You weak little cunt.”

Sandra snarled and charged at Teresa, catching her full in the gut. Teresa grunted, but held her ground. She grabbed Sandra’s waist and held as she flexed her glutes, her thighs, and her calves. She felt a tingling sensation again, and smiled as she felt her babies going to work, this time all over her body. 

Her thighs bloated, bulged, and grew. Her calves inflated to heart-shaped bulges, and her hips and ass thickened with striated muscles. She felt her biceps thicken and push against her forearms, as her triceps expanded with angular bulges. 

Feeling her new strength and energy, Teresa squatted and hefted, lifting Sandra right off the ground. Then she heaved her sideways into a heap.

Teresa’s tank top and formerly loose running shorts looked painted on. With a big shit-eating grin, she flexed into a most muscular pose. As she flexed, she felt her traps surge and crawl up her back, seemingly absorbing her neck into her blocky, muscular torso. Her pecs bloated out, her lats thickened, and her legs bulged ominously.

Sandra just watched, horrified, as Teresa morphed into an olympian muscle goddess right before her eyes.

“Oh yeah, look at me now, bitch!” Teresa flexed her bicep and looked at it with a big grin. “Look at my bicep, it’s so much bigger than yours now!”

She flexed it and it bulged, covered in veins. As she held the flex, Two squirming bulges slowly throbbed. Teresa moaned as a third small bulge grew and throbbed, then a fourth.

“Ohhh yesss…” she moaned. “Multiply, babies, and make me even bigger!” 

Sandra watched in horror as Teresa moaned sensually while the peak of her bicep rose higher by several millimeters. 

“Oh fuck yeah,” Teresa said, releasing her flex. Seeing the look of horror and disgust and Sandra’s eyes, Teresa laughed. 

“That’s right, bitch. I’m a freak!” Then she put her hands on her hips and crunched down her abs. Three rows of apple-sized, vein-splattered abdominal blocks bulged. As she held the flex, a small, slowly throbbing bulge puffed up on each block. Teresa moaned as the small bulges multiplied, two and then three forming on each block. Teresa moaned again as her abs seemingly expanded, adding half an inch of girth to her formerly slender waist. 

Sandra gagged, which only excited Teresa further. She took a deep breath and flexed down again, smiling maniacally as several throbbing bulges migrated downward, and two more blocks rose right at the waist of her running shorts. They bulged out and stretched the waist, causing stitches to pop and fabric to tear.

“More!” Teresa whispered, taking another deep breath. She flexed down again, sending a wave of sinew cascading down the sides of her torso. Her obliques bulged like two muscle-handles, tearing right through her shorts and sending them fluttering to the floor. Beneath her shorts, she wore a small thong bikini which didn’t even cover her unruly, unshaven bush. But Teresa could care less about that now.

“MORE!” She said loudly, feeding off of Sandra’s fascination and disgust. She grit her teeth and flexed, as more throbbing bulges, her worms, her babies, crawled beneath her skin toward her nether region, seemingly at her command. As those little bulges throbbed, Teresa clenched her middle, and hard, angular sinew bubbled and twitched beneath her panties. Teresa rolled her hips as muscle fibers surged through her mid section. Squirming bulges continued migrating to her crotch, as if every one of her worms was following her command to migrate there, until her whole nether region was covered with the little pulsing bulges.

“Ohyesss!” Tersa hissed as she focused her flexing between her legs. The muscle fibers of her pussy slowly expanded. Teresa moaned as her bulging pussy muscles began filling the front of her tiny panties and bulging out the sides. 

“YESSS!” Teresa cried as the lips of her bulging, muscular pussy tore through the front of her panties. Surging with sinewy folds, her thick pussy lips were obscene.

“How’s that for muscle freakiness?” Teresa said as she reached down and felt the muscular ridges of her bulging cunt.

Sandra was utterly disgusted. She couldn’t fathom what had just happened, and she felt nauseous. Sensing Sandra’s discomfort, Teresa became even more aroused. She started stroking her clit. It bulged, and Teresa moaned as she felt two, no three squirming worms thob inside it. It grew thick and hard beneath her fingers, as more and more worms squirmed into it and fed its freakish growth. 

“Unngh, yeah!” Teresa moaned, still stroking, as her clit-cock throbbed with squirming worms. It bulged with muscle, burgeoning to cock-sized  as she stroked it.

Watching Teresa’s hand squeeze and stroke the bulging meat of her mutant pussy and bulging clit-cock, Sandra couldn’t handle it, and puked.

Teresa laughed. “You can’t handle this fucking beast!”

Then she grit her teeth and stroked in ernest. While one hand grabbed and pulled on her big muscular pussy lips, the other tugged and worked her clit-cock. Teresa started panting, watching herself in the mirror as her muscles bunched and rolled with her ministrations.

“OH YEAH, BITCH!” she cried. Her pussy spasmed and spat juices onto the floor. She huffed and puffed, breathless, as she slowly massaged her massive pussy muscles. 

When she finally caught her breath, Teresa looked down at Sandra, who was still on the floor, staring, bug-eyed. 

“Don’t worry, bitch,” Teresa said with a casual flex that sent a cascade of sinew rumbling through her body. “I’m just getting started.”
