Placebo pt. 4

It was an unbelievable fantasy experience that I never knew I wanted. Jenni had gone completely off the deep end with her muscle fetish, and I followed her right over the edge. Now she looked like a professional-level female bodybuilder, tipping the scales at 175lbs at only 5’4” tall. It was amazing.

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

She flexed her bicep, and an impressive, boulder-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.

“Jenni, 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.

“Look at these fucking pecs!” she said with her hands on her hips. She flexed her pecs and watched them bunch up in unison, pushing her firm tits down and out.

“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.

“Let’s fuck!” she said with a flex of her glutes that I caused them to bulge against her panties.

My mouth dropped. She had never been quite this aggressive before, but I can’t say I didn’t like it.

She held her flex and stared at her own reflection. Then she turned and said, “Right NOW!” through grit teeth as she shoved me onto the bed. She ripped my shorts off and pushed her sopping wet pussy down on my hard cock. She was so wet I just slid right in.

“Ungh!” Jenni grunted, releasing her flex, and then quickly flexing down again. Veins and rippling sinew bulged across her arms, her chest, and her shoulders as she began thrusting on top of me.

“Ongh, fuck yeah!” she grunted. “BIGGER!” she said, talking to herself more than me 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, trying to push my diamond hard cock deeper, but Jenni was so big and heavy now that her body barely moved.

“Ooohh yeahh!” she said, putting her hands on her hips 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 she pounded 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

“BIGGER THAN THE MOUNTAIN! BIGGER THAN THE HULK!! I’M GONNA 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! The bigger I get, the hornier I get, and the bigger I want to become!”

“Hell yes! I’m all in!” I said with a huge grin.

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

I smiled, licked my lips, and nodded.
