Candice and Kevin 4

Candiace grabbed a needle and injected me as I faced the mirror. The huge naked mass of muscle bulging and sweating in the reflection was enough to make me get hard again. I rubbed my hands along my chest, waiting for the juice to kick in.

I looked down, flexing my pecs again, loving that he could no longer see below the muscled mounds. I flexed them harder, watching them slowly pump to immense size filling, up with veins ready to burst with power.

“Mmmf yes, you’re so huge!!” Candice moaned as she started stroking her dripping pussy, watching me flex as my pump really started to come on.

I grinned, flexing again, feeling a throbbing power deep inside me that needed to be released. I flexed harder, feeling it grow even stronger inside of me, taking over my body. I moaned, feeling like I was going to cum again. My muscles were twitching uncontrollably, causing striations, veins and ripples to play across my physique. I didn’t want it to stop, I wanted to keep going - it felt so good, so right. I flexed again holding a double bicep pose, feeling the rush of energy fill up my body. Every muscle in my body seemed to swell even, the ones I wasn’t flexing.

“FUCK yeah!! So fucking good….. MORE!!” I rasped.

I snarled, flexing again, hitting a most muscular pose. My body surged with power, every muscle pumped to an incredible size, looking like they would burst. I felt my cock raging and rock hard. Candice just looked on in awe, shoving her fingers in and out of her sopping wet pussy, and pinching her nipples.

“YES! More! MMFF!! MORE!!” I shouted. Candice joined in, shouting “GROW, YOU MASSIVE FUCKING MEATHEAD!”

I flexed every muscle as hard as I could, watching my body tremble in the mirror turning beat red. My thickening cock was gushing mounds of pre-cum on the floor. My skin started to feel like it was on fire as I gritted my teeth, heart pounding faster.

“UNGH, FUCK, MORE!” I moaned.

My body shook violently in the mirror as I felt an explosion inside and let out a roar. My pecs suddenly started swelling impossibly bigger, stretching out from my body, filling up with more muscle.

Candice, still masturbating furiously, was approaching her third orgasm, and shouted, “FUCK YES, GROW YOU MONSTER!”

My back bubbled up with new sinewy bulges, filling up with power and size. My massive shoulders rippled with growth, making his body look incredibly wide. I flared up my obscene lats, watching them get roped in veins and swelling up even bigger. I flexed his massive traps, watching as they crawled up my neck toward my ears, willing them bigger.

My cock swelled larger. I grabbed the shaft and stroked it, feeling it surge with power. I balled up the fist of my free hand, curling my arm as my biceps exploded to a staggering size.

“AHHHHHHH YES!!!!” I roared, flexing again and grunting, as my cock started bucking. I roared again as my cock exploded, sending streams of cum on the mirror.
