Nodak-fun - Switcheroo

The new app ‘AdvEYEsor’ was suddenly very popular among teens. All you had to do was submit a photo and a problem and the team would solve it for you. Truthfully, most kids were using it to show off and hook up and Brad was no different. 

“Help! I have trouble getting laid” He typed and send a photo right after a huge pump at the gym, sure it would get all the girls panties wet. 

The photo seemed to take forever to process and when it was done all these lights flashed on his phone. As he blinked and felt a bit woozy he got a text message from the app. 

15 people nearby want 2 fuck u but were intimidated by ur muscle. Now U should have NO problem :P - AdvEYEsor

Brad looked down and felt a cold sensation cross his body as he noticed his muscles were gone and in their place was a twinky, gay body.

He struggled to text the app again but before he could a couple of his former competitors walked into the change room naked and decided to have a little fun with the fresh meat.

Any other Muscle growth blogs you can recommend me to? Your stories are awesome by the way, upload more often ;)

I’ve been meaning to post of all the muscle growth Tumblrs that I’ve spotted. Lots of them have been sprouting up like crazy in the last few months. Some may not be active any more. I’m just dumping a lot of links in my follow list.

Also not all of them focus solely on muscle growth. There are lots of blogs out there that focus on body swap, body possession or a large range of male transformations.

Anyway, here I go (and not in any particular order):

@magusfan - Just started on Tumblr, but already an accomplished AP/MG writer. Check out his work at CYOC too: http://www.cyoc.net/interactives/user_1441.html

@amalianetwork and his @musclewriters blog too. He runs the weekly caption competitions that I sometimes enter. Also writes lots of hot captions himself.

@hughmichelsen Amazing writer. Terrific with the “reality change” genre. Also has a lot of muscle growth reality change ebooks to his name. Check him out in Amazon and other ebook retailers.

@absqrst Just one of the best MG caption writers out there. Unbelievably hot captions.

Reblog this if you want to pump yourself up to be perfect dumb muscle

Gotta find our bros

One sip, and his pecs jutted out from his chest a little bit more. A second sip, his biceps ballooned out, pushing up and stretching out his shirt sleeves. Third sip, he flipped his hat around without even realizing it. It was on the fourth sip that he got that dumb look on his face. Fifth sip, and he was all mine.

“Flex for me, bro,” I told him.

He put his big arms above his head and put a cocky look on his face.

“Yeah, bro,” I complimented him, “Nice arms.”

He let out a dumb chuckle and continued flexing for himself. He was completely oblivious of his instant muscle growth. All he knew was that he was fuckin’ big now, and he wanted to show it off.

“Fuck yeah,” he said. Damn, his voice had gotten so deep and dumb-sounding.

“I think you’ve had enough to drink tonight, though,” I said. I raised an eyebrow and looked at the bottle that he had continued sipping from. With each sip he took, he was becoming more and more simple-minded. If he kept it up at this pace, I doubted he’d even be able to string a sentence together by the end of the night. 

“This shit is fuckin’ lit, bro,” he slurred, “What the fuck is in this shit?”

“Just a special little serum I invented to help turn you into a dumb, muscular frat bro,” I smiled.

“Huh?” What I had just told him had clearly gone over his head. “Whatever, bro. That sounds like some fuckin’ stupid science shit or somethin’.”

His Cousin’s Hat

The second Jake put on the hat, he could tell something was up. He had snuck into his step-cousin Matt’s room while he was out at the firing range with his dad and uncle. Jake had always had a bit of a crush on hot, red-neck Matt, though he dared not tell his family, and he snuck into his room to see if he could try on any of his clothes. A bright orange baseball cap caught his eye, and he instinctively reached for it and tried it on.

And that’s when the changes started happening. First, he felt himself start to get taller, if only slightly. Part of him thought it was all in his mind, when he felt a sudden soreness in his chest. He looked down to see his pecs inflating outwards, stretching out his t-shirt as his lower abdomen began to suck in.

“Fuck,” Jake whispered, pulling the now tight t-shirt over his head. Abs were beginning to pertrude  where his small belly once was. In addition, two cum-gutters were forming just above his waistline, pointing down towards his legs, which were starting to fill up his jeans.

Next were the arms. Jake felt them stretching, getting heavier and brushing up against his inflating lats. He rushed into Matt’s bathroom to look in the mirror. Sure enough, two massive peaks were forming on his biceps, his shoulder growing broader and his traps snaking up towards his neck.

On his face, his features were subtly shifting, growing smaller and more defined. Facial hair began to lightly pepper his face as Jake let out a satisfied grunt. Wait, he thought, is that my voice?

“Is that my voice?” he asked the ever inflating reflection. It was a deep, husky voice, a bit of a sexy southern drawl peppered in for good measure. “God damn,” he said, continuing to admire the new body, “God da— oooohhh…”

He let out a pleasured groan as the final step of the transformation started to occur. He felt a powerful heat emit from his crotch, and he grabbed for it in shock. And that’s when he started to feel it: his dick, inflating and growing in his grip. He could feel his massive ball sack churning out hot man juice and pumping it throughout his body, which was now starting to look like that of a young muscle model.

When the pumping finally subsided, he unzipped his now uncomfortably tight jeans and let all twelve inches of his thick new cock spill out onto Matt’s bathroom countertop.

Jake looked back up in the mirror at the new man standing before him. His body was perfectly sculpted, every new muscle glistening with hot, post-transformation stress. He flexed his bicep, and his dick jumped up from the counter. He was getting turned on by his own body!

With his free hand, he stroked his new big dick while flexing his bicep. “Aw yeah man,” he started to dirty talk to his reflection in that deep southern voice, “fuck yeah man, look at me. Fuckin’ massive. Aw yeah, I’m gonna make me cum…”

He felt his whole body grow hotter as his dick tensed in anticipation. Every muscle tensed, and Jake felt a wave of pleasure like nothing he’d ever experienced before. He let out a big, manly moan as he shot spurt after spurt of hot silvery man juice onto Matt’s mirror. It felt like he was standing there for hours, cuming over and over, testosterone shooting through his veins as he embraced his newfound man-hood.

When he was finally done, Jake ran his sticky hands over his sweat-drenched muscles, feeling the deep, warm crevices of every singe one of them. He loved his new body, he was just going to have a lot of explaining to do when his step-cousin got back from the range. And a lot of cleaning to do as well…
