Sam pt 3

It was an unbelievable dream come true. My girlfriend Sam had discovered my fetish for muscle women, and then completely embraced it. She was now as turned on by female muscle as I was! As a result, she had taken herself to the gym and started working hard, ignoring her other fitness pursuits like yoga and running in favor of heavy lifting and packing on muscle. And she had been amazingly successful.

“Hey babe, come feel my arms!” she said as she stood in front of the mirror, clad only in a thin sheer bra and matching sheer panties. 

She flexed her bicep, and an impressive, lemon-sized bulge popped out. As she held the flex, a  thin blue vein rose to the surface.

I came up behind her and grasped her bicep. I squeezed and felt its firmness.

“Sam, that’s so hot!” I said.

“Shit yeah, I know!” she said, licking her lips. She ran her other hand down her abs, now rippling with packed muscle. She had a cut six pack, and you could see the outline of oblique muscles.

“And look at my pecs!” she said as she flexed her striated pec muscles, which rippled. She flexed her left, then her right, each one bunching up into a mass of fibers and veins. It was so sexy, I was hard as a rock.

“Who needs tits with a chest like this!” she said with her hands on her hips. She flexed her pecs and watched them bunch up in unison.

“You’re hard, aren’t you,” she said, not taking her eyes off her own thick chest.

“Fuck yeah,” I said.

“Good,” she said. Then she bent over slightly and did a most muscular pose, gritting as she watched muscles and veins pump up all over the reflection of her body. 

“Fuck me!” she said with a flex of her glutes that I caused them to bulge against her panties.

My mouth dropped.

“Now!” she said through grit teeth, as she held her flex and stared at her own reflection. I came right up behind her, pushed her panties aside, and plunged my hard cock into a pussy that was so wet I just slid right in.

“Ungh!” Sam grunted, releasing her flex, and then quickly flexing down again. Veins and rippling sinew bulged across her arms, her chest, and her shoulders as I pounded her from behind.

“Ongh, fuck yeah!” she grunted. “BIGGER!” she said, talking to her reflection as she strained her muscles harder, willing them to grow.

“Come on,” she hissed, talking directly to her muscles. “GROW YOU BASTARDS!” she grunted, flexing harder, focusing on her traps, her pecs, and her biceps.

I bucked harder, slapping my thighs against Sam’s hard ass, but she was so big and heavy now that her body barely moved.

“Ooohh yeahh!” she said, putting her hands on her thighs and flexing her pecs again, and again, and again! Veins grew bigger and more prominent, invading her neck, puffing up on her forehead even.

“COME ON, GET BIGGER!!” she cried, punctuating the words with another massive pec flex. 

She grit her teeth and actually growled, her pecs, traps, and biceps vibrating as I slammed my hard cock faster. 

“GONNA BE FUCKING HUGE!” she shouted, balling her fists and closing her eyes. She flexed even harder, her muscles vibrating with the effort

“GONNA GET SO BIG, SO FUCKING MASSIVELY MUSCULAR, I’LL BE A GIGANTIC MUSCLE MONSTER!!” Her pussy vibrated with the pronouncement and I felt juices gushing. At the same time, I came, pumping spurt after spurt into her tight, vibrating pussy.

She stood, took one more look in the mirror, smiled, and turned. “This muscle fetish is so fucking hot, I’m so glad you got me into this!”

“Me too!” I said with a huge grin. 

Sam started feeling her biceps, pecs, and rippling six pack. “Damn, I’m hot. Ready for round two?”

I smiled, licked my lips, and nodded.
