The Worms 3

Delia was looking through her microscope when the door to her lab slammed open. Startled, she looked back to see a big, muscular bodybuilder dude with ripped tank top that looked painted on, and a pair of male tighty-whitey type briefs that looked like a sock had been shoved into the crotch.

Delia stood and was about to ask what was going on when she saw the bodybuilder’s face and realized this wasn’t a dude at all, but a woman. And she recognized that face.

“Teresa?” she said. Delia instantly knew what had happened. “Teresa, you didn’t…”

Teresa stopped right in front of Delia and chuckled. She flexed up a single bicep, smiled madly, and said, “Oh, I did!”

“Teresa, this is crazy! Those parasites are multiplying in your muscle tissue. I can’t begin to predict the effects-”

“I can,” Teresa said. “And they’re not parasites anymore, Delia. There symbionts!”

She put her hands on her hips and flexed her pecs, which surged forward, tearing her tank top further. Delia’s eyes bugged, but she also felt something unexpected. A sudden stirring in her loins. She had no idea this much muscle, up this close, could be so… erotic.

Recognizing the look in Delia’s eyes, Teresa grinned. “Oh, you like it, don’t you!”

“Teresa, I don’t think-” Delia stopped suddenly as she noticed the small, throbbing bulges in Teresa’s chest. She recognized them, and was about to say something again, when Teresa moaned.

Teresa’s pecs swelled, bulging with thick striations and veins, and Delia’s jaw dropped. She also felt her panties getting wet.

“Oh my god, Teresa!” Delia said excitedly.

Teresa chuckled. “Not quite yet, but once I absorb a few more of these babies, I just might become one!”

Delia’s brow furrowed. “More? But you’ve already got…”

“MORE!” Teresa cried as she strode toward the enclosure.

“Teresa, wait,” Delia said, as she grasped her thick upper arm. The overwhelming musculature of that arm sent Delia’s mind reeling, and all she could think of was how sexy her friend’s body had become.

Teresa roughly grabbed the glass enclosure and threw it to the ground. It shattered, sending glass in all directions, and a goupy mass of brown liquid, invested with worms, in the center. Without Hesitation, Teresa tore off her shoes and stepped barefoot into the pile. She reached down, grabbed hand fulls of the worms, and started spreading them all over her body. She moaned as they crawled over her skin, up her legs, across her back, abs, chest, and burrowing into her muscles. She moaned orgasimically as they started to enter her skin.

“Oh fuck yesss…!!!” she moaned as her eyes rolled back into her head and she shivered with orgasmic delight.

Delia just stared as every last one of her the worms from the tank crawled onto her friend and started burrowing into body. She watched as Teresa shivered, moaned, and then crouched down into a fetal position. She watched as Teresa’s body convulsed, and every last parasite burrowed into her skin.

“Oh my god...Teresa, can you hear me??” Delia said, though she was hesitant to reach out and touch her friend. 

After a full minute, Teresa stopped convulsing and stood. She was smiling broadly and looking down at her arms. She appeared unchanged, still the muscular hulk she walked in as. The only difference was that Delia could see slowly throbbing bulges moving around under Teresa’s skin, almost everywhere.

“Teresa,” Delia said hesitantly. “Are you ok? How do you feel?”

“I feel like a fucking goddess!!” Teresa replied.

“Oh shit, Teresa,” Delia said with worry, “You’ve got so many of those parasites inside you-” 

“I told you,” Teresa said with a chuckle. “Not parasites. Symbionts!”

Then she flexed her arms into a double bicep pose. Both biceps surged into brawny peaks that had to be 25” in girth. With a maniacal smile, Teresa watched with glee as dozens of throbbing little bumps squirmed beneath the skin. Her biceps twitched and trembled. Then they swelled,   bulging with angular sinew, adding inch upon inch of muscle to her bicep.

Delia blinked, utterly speechless at the sight of her friend’s surging musculature growing right before her eyes.

“You see?” Teresa said, releasing her flex. “They’re not parasites. They make me BETTER!” Teresa said with mania in her eyes.

Delia was speechless. She felt both worried and frightened. But she also felt more turned on than she had ever been in her life. 

“You like it. I can tell,” Teresa said with a chuckle. “Watch this!”

Then Teresa flexed down into a most muscular pose, and the squirming worms through her body pulsed slowly. A sound like a water balloon stretching could be heard as Tereasa pecs, abs, thighs and traps slowly bulged and expanded. Her traps reached up past her ears, swallowing her head. Her pecs tore right through the front of her tank top, stretching her skin with bulging sinew. Her thighs vibrated and expanded, and stitches tore on her tighty-white briefs as they began to look painted on.

Delia couldn’t handle the sight of her friend bulging with more muscle than she could imagine, and she threw up on the floor. Teresa chuckled.

“Oh yeah, baby, I’m a freak! And I’m only getting better!”
