Celine 3

The next day, Celine returned to the gym to see Ken doing standing curls with 35lb dumbells. That may have been a fair amount of weight for most, but Celine was way beyond that now. She sidled up beside Ken and grabbed the 50 lb dumbbells and started pounding out curls. Ken looked over, startled, nearly dropping his dumbbells. Celine continued to bang out rep after rep, the thick veins on her biceps engorging with blood. Finally, after 20 reps, she racked the weight.

“Fuck yeah,” she said. “That felt light! I must be growing.” Then she pushed Ken aside and grabbed the 60lb dumbells.

She stood up and looked at herself in the mirror again. “Strong as a fucking bull!” she yelled. She grit her teeth, and started curling the 60b dumbells. To Ken’s awe and surprise, she completed a set of 10 on each hand, though she struggled slightly with the last rep.

“Fuck yeah!” she said dropping the weights. She started flexing into a most muscular and said, “How do you like that, bitch! This little girl can curl way more than you!”

Ken stammered, “That’s… hot!”

Celine smiled. “I weighed myself this morning. 175 lbs. How much do you weigh?”

“185” Ken replied quietly. He was decently muscled for his size, and training hard, but this girl was just motivated beyond what he could imagine.

“Ha, and you’re what, 5’8”? I’m 5’4” and I already weigh nearly as much as you. And I’m getting bigger, baby!” she bellowed. “You better work harder, because I’m gonna keep growing! I’m gonna get way bigger than you!”

Ken decided then and there to bulk up and try to catch up to Celine. She was clearly into muscle, and so was he, apparently more than he ever realized. He needed to bulk up, not just to impress her, but to satisfy his own base desires.

A couple of months went by and Ken made some steady gains. He leaned out and had a nice six pack, and defined muscles. He thought I was pretty big at 195lbs of solid muscle for a 5’8” guy. But Celine somehow surpassed his gains and then some.

She now weighed the same as him at 195lbs and looked like a monster. She had 18” biceps and 30” thighs. On a 5’4” woman with a former 24” waist, she looked enormous. I say a former 24” waist because her abs bloated up with the rest of her. Her waist was now at least 28” because of the beefy abs in her mid section. They looked like a stack of apples, ripped and striated, and her serratus and obliques stood in cabled relief.

Her chest, which used to be a c-cup, now looked like two blocks of solid muscle. She had notches and veins squirming in the groove between her meaty pecs. Her former breasts were nonexistent. They were gone, replaced by a man-shaming chest. She was the sexiest thing Ken had ever seen.

One day Ken saw Celine staring at her reflection in the mirror of the locker room. She had taken to using the men’s locker room, and no one objected because she was more muscular than any guy at the gym. She was topless, flexing her pecs, and watching the muscles roll and contract.

“Look at my huge pecs!” she said. Then she smacked her fist against one. “They are so fucking strong!”

Her nipples were erect, but the muscles in her chest were so bloated that her nipples pointed straight down towards the ground.

“Who needs breasts. They’re useless sacks of fat. I’ve got muscle tits!” she cried, and flexed into a most muscular pose. I was hard as a rock.

She saw my erection in the mirror.

“I see your dick likes my pecs.” She turned to face me with her hands on her hips. She started bouncing her pecs alternately, first left, then right.

“Tell me how fucking sexy my muscular pecs are” she said.

I told her what I thought - that they were sexy, muscular, and hard as steel. I told her that her muscle tits were the best tits I had ever seen, and they made me want to fuck her then and there.

“My muscle tits are so sexy I want to fuck myself!” she declared.

I looked down toward her pussy area, covered by thin briefs. She was clearly turned on because her briefs were soaked with her juices. My god, she was getting horny just looking at the reflection of her muscular pecs in the mirror.

She took notice and said, “God, these muscles just make me so horny.” She chuckled, reveling in the shock on my face. “I’m gonna get even stronger, even bigger, and even hornier!”

Ken blinked. Celine, with the quickness of a cougar, grabbed Ken and pressed her lips against his. She used her thick tongue to push his lips aside and press into his mouth. Ken, overcome with lust, ran his hands all along her thick triceps, abs, and back as his erection pressed against her rippling six pack.

Then she reached down and tore her briefs off. Her clit was swollen and looked bigger than any Ken had seen before.

“Come suck cunt!” she commanded. Ken obeyed. He sucked and sucked until she came again and again. Then she pushed him onto the bench, mounted him, and proceeded to fuck him like an animal. Several patrons wandered into the gym during their lovemaking, but the two were too engrossed in muscle sex to notice. After several climaxes, they finally ended, both breathless. Unfortunately, that incident led to both of them being banned from the gym.
