Erica 4 (Patreon)

Tanya admired herself in the full-length mirror. Just a few months ago, she had been a thin, 5'3" bombshell who was the envy of women on campus and admired by all the boys. She had been proud, and happy, and definitely conceited. But that all changed when that muscle-monster Ericka humiliated her in the hallway. Since then, Tanya had been seething. She was used to getting her way, both with her stunning good looks and the money from her wealthy family. She was shocked and angry when that bitch dominated her the way she did. No one could do that to her.  

So Tanya had resolved that she would never be dominated by Ericka, or anyone else, again. That summer, she stayed at her father's house, close to his lab. She knew her father had been working on a formula for the department of defense - some kind of growth hormone to help soldiers gain lean muscle mass. A little sleuthing scored her the chemical formula for the x33 experimental syrum. It hadn't been tested or approved, and she had no idea what the side effects might be. But she didn't care. The animal testing showed that this syrum increased strength exponentially. So she started taking it, and hitting the gym.  

The results showed. She flexed her new 22" biceps and smiled. When she first started, she wasn't so sure she wanted to be heavily muscular like that bitch Ericka, but she wanted to be *strong*. But as she packed on the mass, and her strength grew, she found herself strangely attracted to the growing mass of muscles she saw in the mirror. She sucked in her stomach and flexed her 8 pack abs, cut and defined between her electric-blue bikini. Her thick abs added 4" of girth to her formerly shapely 26 inch waist, but she didn't care about that. She smacked her fist against her abs with a loud SMACK. They were strong, and that's what she wanted.  

She turned to the side and flexed her pecs, which rippled and bunched under the straps of her bikini. Her full D-cup breasts pressed into her bikini top, pushed forward and upward by her thick chest. The groove down her sternum was more than an inch thick, and her traps were big and prominent, adding girth to her neck. She watched as veins leapt to prominence,  snaking across her arms, her pecs, and around her neck. She was shredded, totally cut, and she was going to make that bitch ericka look like a fat cow compared to her conditioning. She didn't even care that veins invaded her formely smooth and beautiful face. To her, they symbolized her new strength, so when they snaked across her forehead and into her cheeks, showing her increadible conditioning, she welcomed them, even lusted after them.  

She looked down at her thick thighs and calves. Before, she had nice, shapely legs, but now she had two pillars of shredded muscle. Her 32" thighs, thicker even than her waist, rippled with strength and vascularity. Her calves, half hidden by black boots, strained the boot top to overflowing.  Her buttocks were blocks of vascular muscle, no longer round and tight but shredded and hard and angular. It looked like she could crush stones between her ass cheeks.  

It was time to test these muscles. She walked outside to where her father's BMW was parked. She walked behind it and slipped her hands under the bumper. Her quads rippled as she squatted, and flexed her legs. A soft, shallow grunt escaped her lips as she pressed. The rear wheels started to lift, ever so slowly. Veins popped in her forehead and snaked up her cheeks toward her nose as she exerted her strength against gravity and the weight of the car. Her back muscles knotted and her lats flared, straining her top, as her legs straightened and the rear of the car came several feet off the ground. She paused for a moment, then squatted and flipped her elbows down.  

"Hrrruagh!" she screamed as she power the car to shoulder level, quads shaking with fury. She huffed three times. With a quick squat, she grunted and pushed. "Agghh!!" she cried even louder, pushing the rear of the car above her head. "Fuckin' right! I'm fucking super girl!!" She cried, holding the rear of the car aloft for several agonizing seconds. Then she backed away and let the car come flying down with a smash. She did a double-bicep flex, turned and kissed her left bicep. "I'm going to teach that bitch who she was fucking with!"  

Ericka wasn't that hard to find. She had dropped out of school, and was making a killing as a dominatrix. Tanya looked her up and made an appointment, intending to turn the tables on her muscular rival with her newfound strength. How fitting, she thought, I'll have that bitch come to me, on my terms, and then I'll destroy her! The thought turned her on, as she slipped her hand beneath her bikini bottoms and masturbated, thinking of the devestation she would wreak on her unsuspecting foe.  

As the day of the appointment drew near, Tanya doubled her dosage of the x33 syrum and worked out harder than ever. She hit new maxes in every category, shattering records set by mens stength competitions. And the stronger she got, the sexier she felt. She masturbated to her own reflection multiple times a day, getting off on her increasing strength and musculature.  

As the hour of appointment drew near, Tanya situated herself in a chair, and crossed her legs. She wore the same electric blue bikini with matching high heels, only tonight the bikini was strained to bursting with her burgeoning muscles. She reached over to where she kept a bottle of gel-caps full of the x33 syrum, popped three pills in her mouth, and swallowed. She had never taken this much in a single dose, but tonight was the night she would let loose with all her muscular fury. When the doorbell rang, her butler let Ericka in.  

She looked different. Her hair was a buzz-cut, and she had a nose ring and hoops piercing her upper ears. She wore a long trench coat, and Tanya could make out the bottoms of high-heeled black boots.  

Tanya looked Ericka right in the eyes as she stood, put her hands on her hips, and flexed. With a quick snap, her bikini exploded off her body as her muscles flared outward and hardened into striated fury. Her D-cup breasts separated as her pecs pushed them up and out, her nipples pointing toward the floor. Her tightly trimmed bush was exposed as washboard abs cascaded toward her crotch, which was wet with anticipation.  

"Hello bitch. Remember me?"
