Celine 4

Being banned from the gym didn’t stop Celine and Ken from pursuing their muscle building fetish. Instead, they decided to make their own gym, moving in together and purchasing a huge weight set they could use to build themselves ever bigger.

Several weeks Ken was looking in the mirror of their home gym. Along with Celine, he had been eating freakish amounts of red meat, eggs, veggies, and gallons of protein drinks. Ken had gotten results. He was now weighing in at 210lbs of solid muscle at 5’8” tall. 

He stared at his own reflection as he bounced his big, striated pecs. He flexed his abs and saw them visibly ripple. He flexed a big bicep and saw a thick vein running down the middle. Ken was turning into a muscle beast, and he liked it. He felt his cock stiffen as he started feeling his own hard muscles.

“You think you’re big? Please, bitch. I still outmuscle you!” Celine said from behind Ken. He turned around and beheld his muscular girlfriend, completely naked except for a small posing brief.

She was 5’4” and now weighed an astonishing 210lbs, the same as Ken. Because of her short frame, she looked enormous, almost wider than she was tall. She had almost no fat on her at all due to her extremely strict diet and the gruelling two-a-day workout schedule they had maintained. 

Her pectorals looked like two huge blocks of striated beef without an ounce of breast tissue. She had grooves running lengthwise, and pulsating veins crisscrossing in and out of her inches-deep muscle-cleavage. Without her flexing, her traps were bulging, vein-covered mounds on either side of her head, giving her the appearance of not having a neck. Her shoulders looked like giant, striated mellons of beef. Below her man-shaming pecs, her abs jutted out like eight softballs shoved under her skin.

“That’s right, stare in awe at my huge fucking muscles,” she said and flexed her pecs. They jumped and bulged, and her nipples pointed straight to the floor. “I’m going to get bigger, and so freaky that you’re going to lose your shit just looking at me!” she said with fire in her eyes.

Then she slammed her chest into Ken’s and sent him staggering backward. As he fell off balance, she grabbed his shoulders and shoved him toward the bed.

She had become so strong that the force of her shove nearly sent him airborne. He staggered backward and fell onto the bed on his back. She turned and looked at herself in the mirror. She flexed up a huge, 18” bicep and licked it.

“God, I love being so jacked,” she said. “My muscles are so sexy I want to fuck myself!” 

She grabbed a long, thick, veined dildo and placed it on a seat in front of the bed. She unceremoniously sat down on it, taking almost its full length into her sex. She grabbed her own pecs and said, “Watch this muscle girl fuck herself!” and started bouncing up and down on the dildo.

Ken watched wide-eyed and open-mouthed as her muscles rolled and bunched with the motion of her thrusting. Her face became flushed and multiple veins came to prominence on her forehead, and even on her cheeks. God, even her face was getting built!

Ken almost came right then and there. She noticed how near the edge he was and said, “Don’t you dare cum! Your cum belongs to me!” Then she jumped off the chair with the dildo still trapped in her muscular sex. She reached down, grabbed his ass, and pulled him up off the bed. She swallowed his member down to the hilt as his whole lower body was suspended off the bed. 

Ken came so hard he nearly fainted. It felt like he had pumped a gallon of cum straight down her throat. She let go of his ass and let him drop to the bed. She gulped. Then she licked her lips and gulped again.

“MMmmmm!” she moaned. She did a double bicep flex, and then treated me to another astonishing feat. She held the bicep flex and started flexing her lower abs, cunt, and ass. Her abs suctioned inward, her cunt squeezed down on the dildo, and pushed it outward. It ejected from her pussy with a wet slop.

“Shit I’m so jacked!” she said. “And this is just the beginning!” she said as she flexed down into a most muscular pose that had me hard as a rock again.
