Tony stood in front of the mirror, and held up his camera phone, getting what he hoped would be his before shot of what would be an astounding transformation. See, Tony was what would be called a gainer. He wanted to be bigger, and especially fatter–well, and hairier, and just…he was just tired of being him. Smooth and mostly hairless, paunchy but not really fat. He’d tried recipes designed to pack on weight, solutions designed to thicken beards, but nothing had worked well, but then he’d run into Max.
Max had been like him, only worse. Scrawny and short, he’d always wanted to be bigger too. They’d met in a forum a few years ago, and once they’d learned that they lived in the same city, they had struck up a bit of a friendship, but both of them had miserably failed at encouraging the other to gain much more than fifty pounds. However, they found some solace in their own failures, and gathered a small group of others like them whose genetics and metabolisms thwarted them at every turn. Tony had even begun to suspect that something like a relationship was growing between them, when all of a sudden, Max was gone. He disappeared for more than a month, and just about the time Tony had gotten tired of leaving him voicemails, Max had shown up on his doorstep–only it was a very different Max who stepped through the door.

He was…big. Not just with a big gut, but tall too, a good foot taller to be exact. And damn if that gut didn’t look fine on his as well, and the hair! It was everywhere! Max had never been able to grow more than an ugly patchy beard, but the bear who strutted into Tony’s apartment had no such problem. Of course, Tony didn’t believe it could be Max, not at first. It was only after the bear had described some of their time together, and some of their secrets, that Tony began to believe, but that of course left a different question–how? How did this happen?
Tony could tell Max was reluctant to divulge his secret, but it finally came out after a few beers. He’d undergone a medical test for low testosterone, and the medication had worked better than he’d ever imagined. Hell, it had worked so well, he wasn’t going to be able to return to his old life–no one would recognize him. He was being relocated by the drug company, and he wasn’t even supposed to be discussing this with anyone from his past life. Still, he wanted to show someone, and Tony was the first person he’d thought of.
Tony was at first incredulous, and then, he felt a wave of jealousy wash over him. It wasn’t fair. Max had gotten more than he’d ever dreamed of, and he’d gotten nothing. Sensing the shift in his friend’s mood, Max pulled out a strange jar and handed it to Tony. “Now listen carefully. Apply this cream wherever you want to accelerate the growth. It takes a couple of minutes to start, but when it does–you have to be quick, and take a shower a few minutes before you reach your target look, alright? The water neutralizes the salve and washes it away, stopping the growth. You didn’t really think I was going to leave you all sad, did you?” Max said, and gleefully, Tony hugged him, loving the feel of his friend’s new gut against his own small belly.
“Should…should I do it now?” Tony asked.
“Of fucking course you should do it now! But I don’t want to watch. I want to be surprised,” Max said. “So get in there and let’s see it.”
And so here was. Taking a picture of himself, just to remember himself by, and hoping that this wasn’t just some scam. Maybe it wasn’t Max. Maybe it was just some guy who was tricking him into the bathroom so he could steal his stuff while he wasn’t watching–but that was ridiculous. Almost as ridiculous as a salve that could make you grow like Max had grown. But what did he have to lose? He stripped down and started applying the cold cream, focusing on his belly and chest, but then slathering some on his face where he wanted a beard, getting some of it in his hair by accident. He stood there for a few moments, feeling silly more than anything else, when he felt the cream start heating up on his skin, the warmth sinking into him, and a moment later, he saw his gut begin swelling visibly.
He shouted with glee as he watched himself grow, grabbed more globs of the cream and started slathering it on his arms, thighs and ass, before fondling his burgeoning belly, feeling it fill with fat and start sinking down, into an apron hanging down over his groin. Hairs sprouted all over his smooth belly, at first just a thin treasure trail, but then filling in all over. His chest filled in as well, moobs growing full and fat, his nipples growing into thick sausages. His thighs and ass expanded as well, though were a bit slower since he applied it later, and he watched his chin darken with a beard and several chins filled in under his neck, his hair even growing longer from the accidental application. However, as he was playing with his new body, he realized that the growth was only speeding up–and he hurried to the shower, almost tripping over his feet at his new height–he was getting taller even–taller! He thought about just letting it continue, but decided against it, and turned on the faucet, dousing himself with cold water, and he grabbed the soap and started scrubbing down his now expansive form.

With some regret, he realized he’d forgotten to apply anywhere where it might really count. His cock and balls had remained the same size–a measly four inches, and with his new bulk they felt even smaller, but he could always apply it again, right? Just as Max had said, the growth stopped abruptly as the cream washed off his body, and he cleaned it from his face last, letting his beard grow a bit thicker. Satisfied, he stepped out of the shower, and realized he had nothing that would even remotely fit his new frame, and somewhat bashfully, he lumbered back into the living room where Max was waiting.
“It…It worked. I can’t believe it actually worked!” Tony said, but was silenced as Max plowed into him, kissing him roughly and fondling his love handles.
“Fuck, you’re so goddamn sexy like that. This is how I always imagined you should be,” Max said, “I love you Tony. I love you so much!”
The sudden pronouncement caught Tony off guard, and a bit nervous, he broke away from Max and took a couple of steps back. “You…you love me? Is that why you did all of this?”
“Yes Tony, I wanted you to…to come with me. We can be big together man! It’ll be a whole new life!”
Tony gaped for a moment, and tears came to his eyes. He rushed forward and slammed into Max, his sheer weight enough to knock them both over and send them crashing to the carpet with a thunderous clud. “I love you too Max, thank you, thank you,” Tony said as he started stripping the bear out of his tank top and jeans, and found that Max had one more surprise he had buried for him. While Tony might have forgotten to apply the salve in all the right places–Max had not. His cock was a good ten inches long, and quite thick, his balls hanging low, with each the size of a tennis ball. Tony had been so distracted by Max’s new gut that he hadn’t even noticed his new package.
“You like that big cock, Tony? I made it especially for you, and that big, fat ass you always told me you wanted,” Max said, them roughly rolled them both over so he was on top of Tony, who was starting to notice that something was off. Max had never been this aggressive before. Whenever they had played, Tony had been the one on top–and he suddenly didn’t like where this was going. Then he was on his belly, and Max was running the huge cock up and down his crack, and then it was in his hole, and no amount of begging or pleading could make the big bear on him go any slower or gentler.
Certainly the salve had had an effect on Max’s stamina. He fucked Tony for a good half hour, who managed to enjoy most of it, once he’d gotten over the initial pain. In fact, the feeling of Max’s rough thrusts reverberating through his body was so sensual, it easily made up for the rest of it, but the personality change had startled him. Was this even the same Max he had known? The one he had started to develop feelings for? Max reached under and started fiddling with Tony’s cock, making him lose track of his concerns and lose himself in the sex. Max was close, and when he felt the bear’s huge cock begin spasming, he released as well, feeling his jizz shoot over his gut and drip down onto the floor. They remained coupled for a moment, and then Max eased himself off with a grunt and rolled over, where they laid together for a while in the afterglow, until Tony worked up the nerve to ask the question nagging him.
“So…Max. What are the side effects of this stuff? I mean, you said it was still being tested, right?”
“Uh…well, about ten percent of us experienced some personality change–usually increased aggression and libido. I…I fell in that category, but you probably noticed that,” he said, blushing a bit and realizing he might have been a little rough, “A small few had allergic reactions on their skin, some weren’t responsive to the treatment at all, and others, well…they just kept growing. Water didn’t stop it–it only slowed it down, and the risk of that one increases with every application, which is why we can only apply it once.”
“Once? But I wanted…well, I wanted to improve my own equipment a bit, if you know what I mean…” Tony said, “It isn’t fair that you have this huge tool and I don’t.”
“It’s not my fault you didn’t think of it. Besides, I was always the bottom for you. I think having the rolls flipped might be kind of nice,” Max said, rolling on top of Tony and pinning him to the ground, “You certainly didn’t seem to object much, after all.”
“Come on, one little bit can’t hurt. Let me get a couple inches out of it at least.”
“No,” Max said, the domineering tone slipping in without him even noticing, “It’s too dangerous, and that’s that,” he said.
Tony glared at him, but said nothing. He was starting to think he wasn’t liking this personality shift at all. However, their argument was halted by a knock at the door. “Oh…Oh fuck…” Tony said. He had completely forgotten.
“What? Who is it?” Max asked.
“It’s…well, the rest of the guys, they were going to come over for a padding session…I wasn’t expecting you–I forgot!”
“God fucking damn it!” Max shouted. He had counted on being able to spirit Tony away before anyone could know the wiser, but now the rest of the gaining group had arrived, and they certainly wouldn’t let Max and Tony get away without wanting to know their secret. Max scowled, and he realized that what he had imagined as a simple visit to help his lover was becoming quite the gainer’s dilemma.
