Weight can be a big problem for some people and Josh was no exception. Josh had a metabolism that most would kill for. He could eat whatever he wanted and do as little exercise as possible without gaining a pound of fat. On this flip side, he could do hard core exercise every single day until he couldn’t move and wouldn’t develop any new muscle mass. He had the perfect Asian twink body, and he hated it.

All Josh wanted was to be a muscle bear, have a nice sexy gut and massive arms of muscle. He had cast off his desire for a better body as an unattainable wish. That is, until he discovered a weird book in an antique shop. The book appeared to be written in some weird language that he couldn’t read, everything except one page. The section he could read appeared to be a recipe for a shake that would add fat and muscle to your body. It looked too good to be true and Josh almost put it back thinking it was a sick prank, but something about the book felt real. He got the book and ran home as fast as possible, anxious to try out the recipe.

The book was hard to read, only one line was readable at a time. Josh pushed through and added each ingredient at the exact amount specified. It called for ingredients that Josh had tried before, though not in these exact amounts. He thought he was duped until he read the last line on the page. It instructed him to say a specific line of gibberish to compete the shake.

After saying the “magic words”, Josh poured himself a glass and eagerly chugged the beverage. He noted that it had a bizarre taste. It simultaneously tasted like years worth of sweets, iron, sweat, and of all things cherry pie. Josh looked down in anticipation, desperately searching for any change in his waist line or arms, to discover…no change.

He angerly closed the book, “magic my ass” he yelled as he stormed off to go play some video games. As Josh played, he wasn’t paying attention to his body and didn’t notice the slight warming sensation the was growing in his gut.

After playing for about 20 minuets, Josh noticed something. His shirt was a little tighter. The size small shirt was slowly getting uncomfortable around his arms and stomach. Lifting it up, he noticed his stomach slowly expanding. Slowly growing in size. What Josh didn’t know, is that Eric, his roommate and friend who was a white twink, was watching, slowly rubbing the growing bulge in his pants.

Josh had told Eric about his dream of becoming a muscle bear with a big sexy gut and Eric was supportive. He tried to help Josh reach his dream, only to have everything Josh try not work. Eric had not told Josh exactly why he was so supportive. Eric, wanted a big muscle bear to fuck him for years, and he wanted that muscle bear to be Josh. And here in front of him, was Josh slowly turning into a muscle bear with a sexy gut.

Josh was amazed, it was working. With his free hand, Josh jiggled his new gut. It started bouncing and caused his moobs to jiggle and rub against his shirt. Eric let out a soft moan that caused Josh to jump. Josh was unaware that Eric was there and wondered how much he saw.

Josh’s fright caused his growing body to bounce, turning Eric on even more. Eric couldn’t stand it any more. Without removing his hand from his tent, he walked up and grabbed Josh’s belly, squeezing it slightly. Eric had never been so turned on in his life. He needed his big sexy friend to fuck him.

Josh realized what was happening and smirked. He’d secretly wanted Eric’s ass since he first met Eric, and now he was going to get it. Josh pulled out his hard cock to show Eric. Without saying a word, Eric got on his knees and started sucking Josh’s cock while not once removing his hands from Josh’s belly or moobs.

Josh let out a loud moan in a deeper voice than he had before. He had dreamed about having someone play with his belly for years and not that it was actually happening, it was better than he ever imagined. The movement, the heavy feeling, the squeezes, they were turning Josh on more and more as Eric worked his cock. He was lost in pleasure and without warning, came right in Eric’s mouth. This sent waves of pleasure through Josh and he could hear Eric moan in lust.

Josh decided that he didn’t want this to end, not yet. He pushed Eric onto the couch and ripped his pants off, leaving Eric on his back with his legs in the air and revealing Eric’s twitching hole. Josh lubed up his cock and bent over to kiss Eric, letting his new big belly press against his twink friend.

Eric felt the new impressive weight of Josh press down on him before Josh kissed him aggressively. Eric couldn’t stand waiting any more, he needed Josh to fuck him now. “Do it…please.” was all he could wiper before Josh forced his cock deep into Eric’s willing hole.

Josh re-positioned himself so that he was standing up and began fucking Eric’s ass with all he had. Eric was moaning loudly while grabbing Josh’s gut, feeling a complete overhang form and giving him something to grab onto while Josh fucked him as hard as he could. Eric felt the pleasure rising and tried to stop himself from cumming, but Josh’s cock was hitting his g-spot with ever thrust.

Josh was grunting now, doing everything he could to keep himself going forever. He didn’t want this moment to ever end. That is until he looked down and saw streams of cum shooting out of Eric’s cock. The sight was too much for Josh and he felt himself tip over the edge and let his cum fly in Eric’s ass, grunting and almost roaring.

The second time was too much for Josh and he fell on Eric before managing to roll off Eric and grab him in a tight bear hug, spooning him. Josh nibbled on Eric’s ear and whispered, “Wanna make up another shake?”

Written special for Josh (Grommr: thecarnalcook)

Justin was a nerdy 22 year old college student, shaggy and unkempt brown hair, thick glasses, average height, and packing a belly that had gotten out of hand. Justin wanted a change, he was tired of being overweight and ignored by all women, and decided that working out would be a good place to try next.

Justin followed his normal methods of information gathering before starting a new assignment, a trip by the used book store. He admittedly knew nothing about working out nor healthy dieting. His first attempts at weight loss were largely fad diets that had ended with no change to his waist line or him actually putting on more weight. With any luck, The used book store would have something that would actually help.

After browsing for a good hour, and finding some great science fiction books he’d been eyeing, Justin made his way to nutrition and exercise section. Before him stood a wall of books covered with pictures of men and women in amazing shape, body builders, sports professionals, and plenty of books by “doctors” claiming to offer quick results. The sight was overwhelming at first, largely because it was Justin’s first time in his section. He didn’t know where to even start. A large brown book with strange writing stuck out. It felt like it didn’t belong here and it looked older than any of the sci-fi books that he had read.

Out of curiosity, he grabbed it and held it in his hands. Opening it, he instantly realized it was a non English book. Dismayed, he flipped through the pages to look for any illustrations that may be useful even if the words weren’t. As he flipped through, he noticed that a page was in English.

It appeared to be a recipe for a protein bar, one that claimed to make someone as strong as an ass. Justin loved every word of it but the last which confused him. ‘Strong as an ass? Like a donkey?’ Hoping his assumption was correct and the recipe would help him build muscle, he bought the book and went home.

In his kitchen, Justin started reading the ingredients. This turned out to be a challenging task because for some reason he could only read one line at a time and it took his eyes a second to understand the words when he looked at them. Justin paid this no mind though, he was probably more tired than he thought he was and he was making progress.

Once he finally finished the list, he realized that he had all of the ingredients handy, even the more unusual ones like dry grass and sweat from a gym sock, which his jock roommate could provide. He got to work mixing the ingredients, anxious to try it out. The final instruction was weird but strangely it turned him on, the book told Justin that when forming the bars and while baking them, he must be wearing nothing but a dirty gym jock. Justin had already realized that he was working with magic, but why a dirty jock? The point wasn’t important, if Justin wanted this to work, which he really wanted, he would have to follow all the instructions.

After returning from his jock roommates room for a second time, Justin stripped off his clothes and put on the dirty and smelly jock. Despite being grossed out, Justin formed the bars and placed them in the oven for 20 min. While they baked, Justin saw a small footnote that held a warning, “Warning: consumption may lead to addictive tendencies towards this item. Continued ingestion may lead to permanent alterations.”

Justin laughed, of course he wanted these changes to be permanent. If this worked, he probably would never want to return to being a weak nerd. And besides, he was starting to get used to wearing a dirty jock around the house.

Before he knew it, the timer on the oven sounded and Justin pulled out the bars. They didn’t look very edible, but how else is one supposed to get something without some sacrifice. Justin grabbed the first bar and began eating it, noting that it tasted a lot better than it looked. Even the strong taste of feet and cock didn’t bother him like he thought it would.

Justin quickly snapped a before picture, still wearing his roommates dirty jock, to keep as a before picture. Just after snapping the pic, he noticed that he was getting hard, very hard, and in fact his cock was growing. Before long it forced itself out of the jock, showing no signs of slowing down. Justin watched with amazement, not realized that it was now 20 in long and getting a flat head like a donkeys cock nor that this might be bad.

Justin opened his mouth to make a dumb comment on the growth, only to have a bray leave his mouth in stead of words. This too didn’t seem to bother him, if anything it turned him on more and convinced him to start stroking his now 29 inch donkey cock, letting out brays of pleasure as he did. Justin’s mind started growing fuzzy as he stroked. Memories of books, school, and other nerdy things began to disappear form his mind, slowly being replaced by the gym, being a donkey boy, and cock. Lots of cock. Cocks fucking his ass. Cocks going down his throat. And cocks lining up to fill his empty holes.

Justin’s ears started feeling weird next as they started growing pointy and hairy. Even this didn’t worry the horny Justin. What Justin did notice was that his muscles were growing, his fat was slowly melting away, hair was growing on his body making him more manly, or maybe more donkey. The latter seemed to turn him on more as he felt a tail start to grow over his ass.

The tail was too much for Justin and he felt himself buckle was he was about to cum. Another bray left his mouth as thick jets of donkey cum covered the mirror before him.

Justin breathed hard as he slowly regained his ability to speak, the tail and ears disappeared, the hair on his body started resembling human hair instead of fur, and his mind refilled with some of his old thoughts. His big donkey cock also shrank down to be about 10 inches, though still shaped like a donkey’s and Justin liked that.

The experience left Justin exhausted, way too tired to try eating another. He’d save the rest of them for a later date and besides, it was getting late and he needed to get some rest. An unusual thought crossed his mind though, his jock roommate Kevin would be home soon, and he was always looking for an ass to fuck. With any luck, Kevin would like Justin’s new and improved, though not perfect, body. This thought won Justin over and he went to lay on Kevin’s bed, waiting for the jock to come home and fuck him.
