Sam Commission 2

With the quality and the volume of the stuff that Sam had me on, it didn’t take me long to blow up. I was at the gym, wearing what formerly would have been a huge top with cut off sleeves, and big baggy shorts. Only the top was stretched tight over my massively bulging pecs that jutted out like thick toasters, and my bulbous quads and huge, muscular ass cheeks stretched those shorts to near translucency. As I curled the huge 150lb dumbbells, watching my arms bloat with cords of muscle, I could see the outline of my thick cock and full nutsack tight against the shorts. Damn, it felt good to be this muscular. Horny good.

I got home and saw Sam at the kitchen counter, her back to me, as she chugged a huge protein shake. She was shirtless, as usual, because her burgeoning physique meant it was hard to find clothes that fit anymore. She didn’t care. She had a physique to show off. Now, so did I.

I watched her thick lats expanding and contract with her gulps, and admired how her thick glutes jutted out, making the briefs she wore look like a thong. My cock bulged, threatening to tear my shorts, and I felt pressure building in my nut sack.

I walked up behind her and grabbed her butt and  abs. Feeling the freaky ridges of her thick abs, and her rock-hard, bulging glutes, my hard on throbbed, and my balls tingled.

“Hey there, big guy!” Sam said, putting the shake down and flexing her abs for me. They swelled beneath my grasp almost impossibly. My cock throbbed again.

“Fuck babe, your abs are thick!” I said lustily.

“Oh yeah,” she said, turning. Then she flexed her arms. “So are my biceps!”

I felt them approvingly. I could see the lust in her eyes as she started admiring my own bulging muscle. She reached out and grabbed my arms and pecs.

“You’re getting pretty thick yourself, babe!” she said, nearly drooling at the sight of my packed pecs nearly bursting through my top.

“Fuck yeah,” I said, flexing. I heard a tear, my shirt straining. Sam snarled, grabbed my collar, and tore the failing shirt right off. Then she gasped as she grasped my thick, hairy pecs and squeezed, marveling at how little give they had.

My cock throbbed harder, my balls strained, and my shorts tore. I bucked my hips, and my cock was so hard that it tore right through the fabric. I grunted and flexed my ass cheeks, blowing the shorts right off. My huge erection stood straight and hard as my thick nut sack hang down between my legs.

“Oh fuck yeah!” Sam cried, tearing her own briefs off, ripping them in the process. Her pussy was dripping. “These clothes just can’t contain us!”

“Muscles gods like us don’t need clothes!” I said, then grabbed her ass and lifted her up before I buried my cock in her sopping wet pussy. She gasped, squeezing my mid section with her thighs. She moaned as I held her, standing, bucking, fucking my muscled-up girlfriend with my juiced up body. I felt so good, so strong, so powerful.

“God damn,” I grunted, still fucking her wildly, “it feels good to be juiced!”

“Oh fuck!” she cried, “I love it! Fuck, you’re so big!” 

I grunted and bucked harder, faster. “Fuck yeah, and I’m just getting started!”

“Oh yeah,” she cried orgasmically. “Get bigger babe! Get HUGE!”

I started slamming my cock into her, harder and faster, lost in her suggestive images, “Yeah, babe, i’m an alpha, and I’m gonna get bigger, fucking HUGE! Bigger than a god damned gorilla! A GIANT FUCKING MUSCLE MONSTER!”

“OH FUCK YEAH MY MONSTER MUSCLE MAN!” she shouted, orgasming. “GET FREAKY! GET HUGE!”

“OH YEAHH!” I screamed, groaning, “SO FUCKING HUGE!” Then I roared,  my cock bucking, as I filled her with my cum.
