Work Text
Tyler wanted to get the six-pack he had always wanted so he could impress a girl he was interested in. They'd met at college, and were friends, but nothing more than that. Tyler wanted the relationship to go further, and knew that he had to make her fall for him somehow.
Sure, he was fit, good-looking with a toned physique, but he wanted to go above that. He pondered over what he could do to attain his goal, and eventually came upon setting up with a personal trainer after several of his guy friends suggested it and showed promising results.
Tyler was 21, stood at 6'1, and had bright green eyes and a fair complexion. His hair was blonde, and was shaved on the sides but his bangs were somewhat long, usually combed to the side.
He was specifically recommended a man named Nathan. Nathan had trained two of Tyler's friends beforehand, and they both said he'd do great with Tyler. And so, Tyler began meeting with him.
Nathan was muscular, not overly, but noticeably, and was white but slightly tanned. His dark brown hair was short, and he had a full, thin beard. He was only slightly hairy, and stood at 6'5. He had deep blue eyes and a handsome smile. He was 32 and married to a lovely woman of 30.
Two months passed, and Tyler was already seeing effects on his body. They were subtle, but noteworthy. He felt himself becoming stronger and his endurance increasing, and Nathan was always encouraging him and finding new ways to improve Tyler's regimen.
Today was going to be different, however. The two of them met at Nathan's private gym as usual.
"Hey, Tyler! What's up?" Nathan greeted him. He wore a white breathable tank top and black gym shorts with a blue stripe on the side. The shirt fit snugly, showing his toned pecs and abs.
"Hey man! How you been?" Tyler replied. He wore a loose black T-shirt and green shorts.
"Been great! How's the plan going?"
"Really good, I feel myself improving on the daily. I've noticed I'm starting to get a little buff!"
"That's awesome! And that reminds me, I've got something new for you today."
"Oh, what is it?"
"A new diet plan that I've studied. I've seen many recommend it for muscle-building, it really helps you bulk up! I've even started it myself, 'cause I think I could use some extra. So, basically you wanna eat things like this..." Nathan showed him the plan on his phone. There were pictures of nuts, avocado, dark chocolate, peanut butter, cheese, dried fruit, and smoothies. "I know I've been telling you to eat stuff like this in moderation already, but now you want to try and get even more. You need high calories and fat to build muscle, it's really important at the stage you're at."
"Hmm...okay. That makes sense. I'll start trying to eat more foods like that."
"Awesome! Now lemme just send you this so you have it to look at..." Nathan texted the info to Tyler, along with providing links to articles pertaining to the subject.
"Thanks! I just got it. I'll start on the new plan as soon as I can."
"Cool! You'll be ripped in no time dude! I just wanna add that along with this new diet, you should also..." Nathan proceeds to give him exercise instructions, also sending them to him. Tyler agrees to the new plan, and the two of them proceed to warm-up, then go on with their shared workout.
Afterward, Tyler went shopping for the foods he'd need, making sure he had everything required by this new plan.
Nathan went on his own way also. He was surprisingly really hungry afterward, so hungry that he decided a "cheat meal" wouldn't hurt. He ordered a double quarter pounder meal from the drive-through at McDonald's, and devoured all of it within minutes right in his car in the parking lot. He then drove home, his stomach full of greasy junk.
Six months since then had passed, and the trainer and his client stuck to their new dietary plan, though things had slowly begun to backfire...
You see, the two of them had both been eating more than they usually had in order to bulk up, but this also resulted in somewhat of a loss of energy. Unbeknownst to the two of them, they were beginning to spend considerably less time exercising as they should, and the consequences of this began to emerge.
"Tyler! What's up my man?" the two exchanged a handshake.
"Nothing much, Nate. How's your week been?"
"Been great, I think I'm really starting to see results," he flexed his arm. Results? There were results alright. Where Nathan's firm abs once were was now a round gut. It pressed against his tight compression shirt, showing the outline of his big, deep navel. His pecs had become flabby also, and while he had always had big nipples, they now seemed even bigger, protruding beneath the fabric of the shirt. Nathan was in perpetual denial of having gained any weight, however.
Tyler had become quite similar, his previously flat stomach replaced by a soft potbelly, and his chest pudgy with puffy nipples. His clothes had also become quite taut on his body, and only became moreso by the day.
While not extreme or very obvious, the pair had definitely put on weight since this new diet, and it was more than apparently not muscle. They'd both lost all their progress, in addition to gaining 30 pounds of pure fat in just 6 months.
"I think I'm seeing results too!" Tyler was just as in denial as his trainer was. "I'm glad you came up with this new plan for us!" he rubbed his own nipple in his shirt.
Tyler even brought snacks to the gym: a bunch of dark chocolate peanut butter cups and some raisins. The two of them stood there and talked for quite awhile, Tyler even sharing his snacks with Nathan. They ended up not even exercising today, neglecting the whole purpose of their meeting.
"See you next week!" Tyler fist bumped Nathan.
"Yeah, see you then bud."
The two of them went their separate ways.
Upon arriving home, Nathan was met with the smell of freshly baked cookies from his wife. He ate nine of the twenty rather large cookies, and thanked his wife for them, telling her how delicious they were. He then took a quick shower, and headed to the bedroom. Then, he remembered a business meeting he had at the office he worked at tomorrow.
"Damn, I forgot I need to get my clothes together for tomorrow," he opened up his and his wife's shared closet, taking out his suit jacket, dress shirt, and slacks. His wife was busy talking on the phone in the living room, so he had time.
"Lemme try these on and make sure they look good," he said to himself. He managed to hoist the pants over his thicker ass with a bit of difficulty, then struggled with his belt, finally managing to get it fastened on the last hole, though he probably didn't even need it. He slipped the dress shirt onto his arms and back, followed by the jacket. The real problem came when he had to button the shirt, he forced the buttons one by one, sucking in his tummy when he got to the bottom. Finally, he got them all done, and let his gut back out. Doing this made the shirt very tight, and openings appeared between each set of buttons near the middle and bottom where his gut was. The buttons looked ready to pop off at any moment.
"I don't remember this shirt being so small..." he stood in front of the mirror. "Maybe it's from the muscle I've been gaining? Yeah, I'm sure it's just that," he subconsciously pulled one of his nipples, which could be seen rather clearly protruding beneath the shirt. One of the gaps in the shirt showed his belly button, and the gaps up and down from it showed the thin hair around it.
He actually thought he looked pretty good, so he decided to take a photo for Instagram. He posted it to his story with the caption "Meeting tomorrow, not looking forward to it. lol." This story got a lot more likes than his stories usually got for some reason, and when he saw in the morning he was perplexed, but just thought everyone else probably thought he looked good too. And yes, he went to the meeting like that...
Time flew by quickly, and soon enough, a year had passed since all this first began. The trainer and trainee duo had seen major improvements with this passing of time as well!
"Tyler! What's *BUUURRP* good my man? Ugh, excuse me, just had lunch at Popeyes before I came here," Nathan high-fived Tyler.
"Oh, just the usual I guess," Tyler replied.
And, coincidentally enough, the two of them were wearing the same clothes today that they worn when they had first started this plan!
Nathan's gut had become massive, now very soft and round, sticking out nearly three feet. His chest had grown into a set of fat moobs, with gigantic nipples and areolas to match. The tank top was now so small on him that it only covered half his gut, leaving it to hang out freely and wobble with his every move. He had a very deep, gaping navel with dark hair around it. His areolas also peeked out the sides and had a little bit of hair around them, and if he moved in a certain way, one of his nipples could pop out. He also now had thick side rolls and love handles which hung over the waistband of any shorts he wore. His ass, thighs, and arms had become chunky, and his ass was so wide and fat that he couldn't pull his shorts up all the way, so his crack was showing. His butt was also somewhat hairy along with his legs. He now weighed in at 357 pounds.
Tyler shared a similar appearance. His tummy had fattened up nicely, becoming squishy and globular with a giant deep navel in the lower center. While not as hairy as Nathan's, Tyler had a thin happy trail below his belly button. His shirt fit much like Nathan's, his tummy basically on full display. His nipples were huge too, and he had a pair of moobs like his trainer's. His fat ass showed out the top of his shorts, as they were also much too small.
"So, uh, ready to get started?" Nathan played with one of his nips absent-mindedly.
"Sure! What are we *UUURP* gonna do first?" Tyler pushed in his own nipple. It stayed for several seconds, then came back out and was hard.
"Did you eat before you got here too?"
"Yeah, I had a large pizza and breadsticks from Domino's."
"Nice! Anyways, let's starts with some jumping jacks. We're going for twenty."
The two of them did so, and their bellies bounced up and down, and their shirts rode up even more. After only five, they gave up.
"Let's take a short break..." Nathan plopped on the floor, followed by Tyler, both guys already all out of breath. They were both already out of breath. Tyler took a sip of his smoothie he'd picked up next door. Nathan also had one of his own, and took a drink.
"Smoothies are actually *urp* better than water for working out, helps keep you energized," Nathan explained, rubbing his nipple which was now exposed. He did this a lot.
"Yeah, I can see why," Tyler was also rubbing his own nip still in his shirt.
"Now let's try something else. Stand up and reach down to your toes," Nathan stood, reaching down, but he...couldn't. His fat gut was hanging down and he couldn't even see his toes. Tyler experienced much the same.
"Am I doing it well?" Tyler asked.
"You're doing great dude," Nathan answered. "You can stand back up now," he gave up, raising back up and attempting to pull his shirt down more, which was utterly pointless.
"Hey, Nate, do you think uh..." Tyler trailed off.
"Do I think what?" Nathan questioned.
"Well, um...do you think we're uh...getting kinda...fat?"
"You serious right now bro? What the hell are you talking about?"
"Dude, literally uh..." he lifted his own belly and dropped it, then tried adjusting his shirt to no avail. "This."
"I don't *urp* think so. After all, this is bulk weight, not flab weight if that's what you're asking."
"If you say so..." Tyler shrugged. He paid it no mind beforehand, but now he was looking at Nathan, particularly his heaving gut.
ππ΄ π©π¦ π’π΄ π§π’π΅ π’π΄ π π΅π©πͺπ―π¬ π©π¦ πͺπ΄? He wondered. All of a sudden, something came over him, and his cock went hard.
Nathan took a moment to look Tyler over also, and...he found his dick becoming hard too? He was getting nervous.
"Now, how about we try some, uh, sit upsβ"
"Sit ups, with a π£πͺπ¨ π§π’π΅ π¨πΆπ΅ like this?" Tyler stepped forward, picked up Nathan's belly and dropped it. "I don't think so dude."
"What are you talking about?" Nathan frowned, his boner now even harder.
"This!" Tyler patted his belly and rubbed it. "The wife been feeding you well?"
"Uh...yeah I *urp* guess..."
"You guess? This says otherwise," he felt the hair around his belly button and stuck his whole hand inside it.
"Okay, you're right. I've really been slacking off."
"At least you finally *urp* admit!" Tyler stopped what he was doing and laughed.
"You're not too thin yourself! How's your girlfriend's cooking?" Nathan patted Tyler's gut.
"It's great, and I'll actually admit I'm fat," he returned, shrugging.
They continued talking, once again not exercising as they always did nowadays, and time flew by and it was soon time for both of them to head home. They said their goodbyes and departed.
When Tyler got home though, a weird feeling came over him. He knew what he needed to do though.
He made his way to the bathroom, preparing to take a shower. He struggled out of his clothes, then got in the shower. His boner wouldn't be satisfied until he took care of it, and that's exactly what he did.
He thought about himself and his trainer, how badly they'd let themselves go. How neither of them fit in any of their clothes anymore, and how they'd both grown absolutely obese and become shells of their former athletic selves. He stroked his dick faster, thinking about how Nathan's gut felt when he played with it. He wished he could've played with his nipples too. Tyler played with his own nips and belly with his free hand, and quickly reached his climax. Perhaps he had been bisexual all along...
