The Worms Part 1 - A Muscle Growth Story

“But they look like worms,” Teresa said as she stared at the glass enclosure.

“They look like worms, but they’re actually parasites,” Delia responded.

“How are parasites supposed to help stimulate muscle growth?” Teresa asked. Her curiosity had been sparked. 

Teresa had always been athletic and an admirer of female muscle, but she lacked the genetics to really build the kind of muscle she wanted. Her friend Delia was a researcher working on scientific cures for people with low muscle density, but Teresa was thinking of other applications for this particular experiment.

“Well,” Delia said, “These parasites naturally produce a hormone that stimulates muscle growth in mammals. In their life cycle, they burrow into muscle tissue, secrete the hormone, and stimulate growth in the tissue. Then they can lay eggs and multiply in the resulting additional tissue. It’s their reproductive cycle.”

“So they end up what, eating the muscle? That’s not good for your goal,” Teresa said with a wrinkled nose.

“Well, normally, yes. The organisms multiply and eventually it causes problems for the host system. But these are genetically modified to secrete more hormone, and a more potent form. In theory, it should generate more muscle growth than the organism needs to reproduce.”

Teresa nodded. “That sounds promising. So what do you do, stick one of these worms in the patient?”

Delia laughed. “Ew, no. Who would want a worm crawling all up in their muscle tissue?”

Teresa blushed. Well, if it promoted serious muscle growth, she just might. It was kind of freaky, and that had a certain attraction for Teresa. She had always been attracted to the freakier side of things, which is probably why she was into female muscle in the first place.

“Besides,” Delia said, “With the success we’ve had in enhancing the formula, the results could be scary. There’d be no way to stop the parasites from breeding and multiplying, and they would spread through the patient’s tissues. Who knows how much hypertrophy would result.”

Teresa felt a small well of excitement. “So by eating one of these suckers, you could turn someone into a worm-fueled arnold!”

Delia chuckled again. “Maybe, but I don’t know if the FDA would sanction that kind of mad scientist experiment. No, our goal is to find a way to extract the hormone and administer it as a drug to help people stimulate muscle growth.”

“Oh,” Teresa said, nodding. “And how far off is that?”

“Unfortunately, it’s probably years. If we can keep getting the funding,” Delia said.

Teresa was disappointed in that response. She didn’t want to wait years.

At the gym, Teresa did her normal workout routine, lifting as heavy as she could to build as much muscle as she could. Unfortunately for her, her 5’5” highest, 110lbs body was built waif-like, and so heavy for her wasn’t nearly as much as she’d like.

That’s when Sandy came over. That bitch was built like a brick shit house, and she loved to flaunt it.

“Move over, skinny,” the brawny blonde said. “Let a real woman show you how to lift.” 

Then Sandy bent down and hefted the 35lb dumbells and started doing hammer curls. Teresa watched her tanned biceps bunch and swell with envy.

Sandy racked the weight and chuckled and flexed a sizeable bicep. “Maybe if you work out a bit harder, skinny, someday you’ll have guns like these” then she walked away.

Teresa sighed. With her genetics, that would probably never happen.

That night, Teresa slept fitfully. She dreamed about worms and muscles, growing big and strong, and dominating Sandy at the gym. When she woke up, she felt her small, thin arms and sighed. That’s when she resolved to try something drastic.

She had waited until the next night to sneak into the lab. The budget on the project was low, as was the security, so she was able to sneak in easily and locate the glass enclosure where the little worms were living. 

They looked innocuous enough as she watched them wriggle through tan-colored liquid. She wondered if they could really help her. She touched her finger to the glass and it looked like one of the worms started wriggling toward her. It was weird, but while most girls might be repulsed by the little worm, Teresa felt a kind of affinity… like she wanted to touch it. It might be just in her head, but she felt like the little worm wanted to touch her, too.

Quickly, before she could think too much about what she was doing, Teresa reached in and touched the wriggling creature. It crawled onto her finger and she drew it out of the enclosure. She watched as it slowly crawled up her arm. Again, she wasn’t repulsed, just curious, even calm. She watched as it found the meaty area of her forearm muscle, and then began to burrow into her skin. She felt a slight prick of pain, but then a kind of warm, calming pleasure that spread from her forearm to her chest. The fuzzy warm sensation faded.

Teresa snuck out, wondering what she had just done to herself. She waited for changes to happen, but hours became days, and she felt little. Soon, she forgot all about the parasite. But she kept going to the gym and started noticing that little by little, she was increasing her maxes in every area. Could it be the parasite? Or just her new workout regimine?

Several nights later, Teresa had a weird dream. She dreamed that she was lying in a bed of worms, wriggling and squirming. But instead of being freaked out, she just lay there and enjoyed the squishy feeling of little worms moving around her body, almost like a message. It became almost erotic, and her pussy started getting wet.

Things in the dream got weirder. The worms suddenly began adhering to her skin, adding mass to her own muscles. She stood and watched as her body absorbed the worms and her muscles expanded. She felt an orgasmic delight as she flexed and watched towering biceps bulge and grow. She looked down and flexed her quads and watched them bloat and swell with mass. She looked in the mirror and flexed her formerly  non-existent pecs and watched as they rumbled beneath her skin and undulated with growing mass. She moaned and stroked her now wet, protruding clit, the sight of her own growing mass as erotic as she had ever imagined.

In her dream she was screaming, “Yes, yes! More, more!” as her muscles vibrated and shook. She came like a torrent, then she woke up.

Sweat had pooled on her brow, and she had creamed her panties. Unfortunately, her body was still the same, though slightly more defined thanks to her new workout regimen. Her lithe body now had a defined six pack, and she ran her hands along it and felt the bumpy ridges. She might not have huge, freaky muscles, but she still enjoyed the feel of the solid definition of her abs. Her other arm felt her small but well-defined tricep. She squeezed and felt satisfaction at its firmness. 

Feeling up her own small but defined muscles was turning Teresa on. She reached down beneath her panties and started stroking and fingering her clit, pushing and pulling on it as she thought about what it might be like to have bigger, thicker biceps, rippling pecs, bulging thighs. Oh god, it made her so horny, just the idea of being bigger, thicker, wider… 

“More…” she whispered, feeling her climax building as she imagined big bulbous traps swallowing her head.

“More!” she moaned as she stroked harder and faster, imagining lats growing wider than her elbows, and bulging rows of abdominal muscles protruding from her mid-section.

“MORE!” she cried, her imagination running wild with images of muscles surging with craggy peaks from her freakishly hulking body. Her pussy spasmed and squirted as she came harder than she ever had before.

“Wow,” she sighed. “I didn’t realize just how crazy my muscle fetish could go!” It felt a little weird, and a little dirty, but she decided that she liked it.
