Courtney 3

Four more months had gone by. Courtney didn’t just keep going, she kept increasing. She upped her calorie intake, inhaling pounds of meat and 4,000 calories a day. She was in her bulking phase, she said. I liked it, a lot. Every article of clothing she owned looked like it was getting smaller and smaller on her. T-shirts were stretched weirdly over the expanding frame of her upper body. Her quads bulged through her tights, threatening to tear right through them. Even her underwear barely fit, her bulging ass threatening to tear right through her briefs. As for bras, I don’t think she even wore them anymore. Her pecs were thick, beefy, and needed no support.

One day I came home to see her doing her “extra credit” work out, which meant her third workout of the day. She was doing push ups again, only this time she was saying, “hundred ninety-seven, hundred ninety-eight…”

Her brow was covered with sweat, and I could see a couple of veins bulging around her temples. I noticed with a gasp that she wasn’t wearing a shirt. I could see the full glory of her traps, delts, and triceps bulging with her motions. I was instantly hard.

At 200, she jumped up, breathing heavily, but not breathless.

“Oh good, you’re home,” she said in a weird echo of what happened months ago. Only this time, she was much more muscular.

My eyes traced her bulging pecs, not just man-sized, but bodybuilder-sized blocks of striated muscle. Her abs, obliques, and serratus bulged with rippling muscle, looking like a thick plate of muscle rather than a waist line. Her quads bulged out, stressing her spandex briefs to the max. I could see the definition in them even when she wasn’t flexing.

My 115 lbs wife now weighed 160 lbs, just 15 pounds shy of my weight. Thinking of that made my cock twitch even harder.

“Come on, I want to see how many pushups I can do with you on my back,” she said, getting down on all fours.

This time, I jumped to comply. I hopped on her back, my hard-on totally pressing into the small of her back. She felt it, and with incredible muscle control, contracted the muscles of her lower back.

“Ungh!” I moaned, and she chuckled.

“Very nice hun, but save it for later… we have work to do,” she said, dropping down into low plank. I held on tight, grasping her thick pecs and feeling the striations as she pressed my weight up. I was amazed at how easy this seemed for her, as she pressed rep after rep with small, girlish grunts. My hands roamed to her delts and abs, and I got more and more excited.

“Keep a good grip, hun” she said as she continued to rip rep after rep, moving faster. I was forced to grip more tightly or get bucked off.

“Twenty-nine,”  she panted, “Thirty!”

She bucked me off and I flew into the air and landed on my side with a thud. She stood, slowly, and smiled a big shit-eating smile. My eyes went wide as she flexed down into a most muscular.

My cock bucked and I moaned as I saw her pecs bulge and ripple, expanding forward by an inch, as thick biceps pressed into the sides of them. Her triceps exploded with thick ropes of horseshoe-shaped muscle, and her traps bloated half way up her neck. Her lats flared, making it look like she doubled in width. Even her abs bulged, thickening and rippling with steel-hard muscle.

I nearly came right there, but Courtney was having none of that. She stalked forward and practically tore my pants off. My cock sprang up, ramrod straight and hard as a rock. She grasped her briefs and pushed them aside, then squatted down on my cock. It sunk right into her dripping wet pussy.

I moaned again, thinking how wet she was. She must have gotten turned on just from lifting me on her back! This was a vicious cycle of muscle-lust now- the more muscular she got, the more turned on she got, which only motivated her to get even bigger.

Courtney rolled her hips forward and rested her hands on her thighs. Then she started alternately flexing her pecs. She massaged my cock with only the slightest roll of her hips, but it was enough, and I moaned watching her abs striate and flex with the movement.

“Go ahead, babe,” she said, continuing the flex show by alternately flexing her biceps, traps, and pecs. “I know how much these muscles turn you on… go ahead and blow your big load right into me!”

She stared right in my eyes and cranked a big most-muscular. The sight of her pecs squeezing together, hard and striated, and bunching together…I couldn’t hold back and cummed harder than I ever had in my life.

Courtney felt it and moaned, feeling my cock pump spurt after spurt of hot cum into her tight pussy.

“That’s right, babe, give it all to me!” she moaned, reaching down to her clit and rubbing it. Was she getting off on her dominance? She had to be.

She got up to her knees. Still rubbing her clit furiously, she crawled forward, inching her pussy closer to my face.

She was moaning and panting now, working herself up to a fury.

“Yes.. yes.. Yes…” she stroked, “take it, babe, take it!” she cried.

Then she came. I’ve heard of women squirting before, but never experienced what I had then. Courtney’s pussy gushed, sending waves of our mixed cum onto my face. Courtney screamed and moaned, obviously overcome with lust both for her muscles, and her ability to dominate me so easily.

Gasping and panting, we both collapsed. Courtney was the first to recover. She got up, sauntered over to her dumbbells. They were no longer the 10 lbs things she used many months ago - these were 45lbs each. She grabbed them and started cranking out bicep curls.

“Unh, yeah, I love these muscles,” she said. “I can’t wait until I get even bigger!”
