Don’t swim in the Seine

by Musclesaber    and Bigmusclenm   

After a fun night with an Olympian, Adam is in for a rough morning when he gets into the river Seine and finds out why athletes shouldn’t have ever gotten into that river. Will he be able to get his body under control before the big race or will his swelling midsection make the star swimmer miss the biggest event of his life?

The sunlight shone into the small room in the Olympic Village. Adam blinked his eyes a few times and groaned as he stretched out his limbs. Taking in his surroundings, he saw he was lying on a man’s big chest and body. Lifting his head up, Adam saw a pec shelf in front of him rising up and down with the big bear’s breaths. Adam took a few seconds to take in the sight of his lover’s chest, scratching it and groaning again as he yawned awake.

Rolling over off of the big man, Adam slugged his way out of the bed. Standing up, he realized he was naked. What the fuck did we do last night? Adam thought. He clutched his ass as he walked over and picked up his clothes. He bent down and felt a strange firmness in his lower abdomen, making him groan as he straightened up. He looked down and noticed a slight curve on his lower abs, his hand immediately moving to caress it. As he processed the sensation, something clicked in his mind, making him realize his midsection felt bloated due to the big man’s cum. So much for those no-sex beds. The bear in the bed snored and rolled over onto his side.

Adam quietly started putting on his clothes. Tugging his tight shorts over his muscular ass. “Ooo!” Adam sharply inhaled as his ass felt sore. “Fuck, you must be big all over, Joe,” whispered Adam, glancing at the big athlete’s lower body covered by the sheets, trying to find any signs of the likely impressive manhood. He pulled his tight athletic shirt over his pecs and 6-pack abs, feeling it stretch more over his lower middle as he tiptoed towards the door. “Sleep tight, Joe. I’ll see you later,” whispered Adam as he closed the door behind him.

Out in the hall, Adam quickly walked back over to his room. His steps were careful due to the soreness in his ass and hips. At 24 years old, he embodied the pinnacle of physical fitness. Standing at 6’3”, Adam was a towering figure, his broad shoulders and powerful frame immediately demanding attention. His chest was broad and solid, his pecs well-defined and firm, a result of the intense upper-body workouts expected in an expert breaststroke competitor. Below his chest, his abdomen was a masterpiece of muscle. His six-pack abs looked carved into his torso, each muscle sharply defined. His well-developed obliques added to the impressive perfection of his frame.

Adam’s biceps and triceps were thick and muscular, the kind of arms that could effortlessly propel him through the water at impressive speeds. His legs, just like the rest of his body, were thick and muscular, with quads and calves that were strong and defined. His thighs were powerful, yet not overly bulgy, a balance that gave him both speed and endurance in the water.

Adam’s facial features could only be described as strikingly handsome, with a square jawline and high cheekbones that drew most people’s attention. People gasped at his cute, handsome face wherever he went. His reddish-blonde hair, still slightly tousled from sleep, caught the early sunlight, giving it a warm, golden hue. The color contrasted sharply with his deep blue eyes. A cute, warm smile adorned his face as he approached his room, already thinking of going back to Joe later today.

Entering his room, he slammed the door behind him and saw his friend and bunkmate, James, stretching. The tall 6’6” swimmer let out a sigh of relief when he saw Adam walking in. “There you are man! I thought you were gonna miss warm-ups.” James was dressed in nothing but a robe and his speedo.

“Sorry, sorry, long night. One of the American shot putters won gold and was buying everyone beers at the pub,” said Adam as he started changing into his gear.

“That and a late-night rendezvous at his apartment in the village makes for an even longer night. We gotta go, big guy!” Adam struggled to shove his legs into the speedo as James stood there with his goggles in hand. Pulling on his tracksuit, Adam hopped his way over to the door.

“I’m coming! I’m coming!” Adam ran out the door after James, and they jumped on a shuttle headed towards the river with many of the other swimmers.

“I’m excited to swim in the Olympics, but really in this river? I’m worried about getting sick swimming in it. The Seine isn’t exactly the cleanest river,” said James as they rode the shuttle.

“Eh, I think it’ll be fine. I’ve swum in worse. Also, they’ve been cleaning it nonstop since they announced the games were gonna be here,” Adam replied with a cocky tone in his voice that made James grunt in disagreement.

“Yeah, but didn’t you see the reports? The women were getting sick yesterday after their races. I don’t wanna get in there and possibly get E-Coli when I get out,” James added. “The water doesn’t look…sanitary.”

“Calm down, ya pansy. It’s fine. It’s just water. Maybe we’ll get superpowers like in the movies! Wouldn’t it be fun to become a fish boy? You won’t care what water you swim in cause you can breathe underwater.” Adam seemed less worried about the dangers of the waters and James’ face looked disgusted as they arrived at the river.

“You have fun with that, chum.” The pair looked at the mucky waters of the Seine River. Adam didn’t wait for his teammate and stripped off his hoodie and track pants, revealing his toned swimmer’s physique. His abs were well-defined, and his muscles honed from years of rigorous training. He jumped into the water without a second thought; splashing his friend in the process.

“Come on in, James. The water’s fine.” Adam laid back in the water and started kicking away from the shore with his abs, pecs, and head floating above the water. The water was cool against his skin, a refreshing contrast to the warmth of the morning sun.

“Yeah, we’ll see about that, mate.” James hesitantly put one foot in the water and then another. Slowly submerging his whole body in the water. “God, this is going to be terrible to swim in.”

“Don’t be such a wanker. It’s fine. Totally normal.” As Adam fully dunked his head in the water, he groaned a bit as the water got into his system. Unbeknownst to him, Adam’s body was going through an odd transformation. The cum from the massive track star he’d been with the night before made contact with the water. A strange sensation began to settle in his lower abdomen—a bloated, heavy feeling that he couldn’t quite place

Coming up to breathe, Adam groaned again and shook his head in the water. “You good bud?” asked James as Adam gasped for air.

“Yeah, yeah. Just a cold pocket right here,” said Adam as he put his hand to his midsection, his abs slightly bulged out in front of him. He remembered the bloated look on his lower abs earlier, so he ignored this new feeling, but the sensation persisted.

“Come on lads! Let’s go! Let’s go! You guys need to get warmed up!” yelled their coach.

“Yes, coach!” replied the swimmers. They all started swimming from one side of the river to the other as Adam started to feel strange. He shoved the feeling away and kept warming up. With every stroke he took, he felt his stomach bowing out under the water. It was as if something was shifting inside him, moving and settling in a way that was unfamiliar to him. But he was too focused on his swimming to pay much attention to it.

His lower abdomen began to swell, and his abs disappeared as he kept swimming in the water. His midsection growing out like a balloon inflating underneath the water. The change was subtle at first—a slight rounding, a softening of the skin—but it quickly accelerated, his stomach expanding with each passing second. His belly quickly grew from being nonexistent to looking like he had a large meal to bulging out below him like he’d swallowed a volleyball. Yet Adam was focused on warming up and nothing more.

Adam’s powerful strokes began to falter as the bloated sensation became impossible to ignore. He felt a tightness in his skin, a growing pressure in his lower abdomen that made it difficult to move as fluidly as before. He frowned, slowing his pace as he tried to understand what was happening to him. His belly continued to swell, the taut skin stretching as it grew larger and larger. However, he never noticed what was really happening until he was getting out of the water after practice.

“What the hell?” exclaimed James as Adam hopped out of the water.

“What?” James, the coach, the other swimmers, and numerous spectators stared at the swimming star in shock, looking at his belly.

Adam looked down, and his mouth dropped open. Jutting out in front of him instead of abs was a belly the size of a basketball. “What the fuck is this?!?”Adam’s heart raced as he placed a trembling hand on his belly, feeling the firmness of the swelling. His skin felt tight and itchy, stretched thin over the rapidly expanding mass. Adam’s breath grew shallow as he tried to process the scene.

“What did you do, Adam?” asked James through gritted teeth. Adam’s belly looked bulbous, swollen like a ball that had been inflated too much.

“Nothing! I didn’t do anything! You saw me! I got in the river with abs and left with thi—” Adam cut his words short as he put his hand to his mouth and his cheeks puffed out. “Bbfff oh no,” he muttered as he shoved his way past the team. His big belly sticking out in front of him and bouncing with every step.

“Adam where are you going?” asked James as his teammate ran towards a building. Not paying attention to anyone, Adam immediately found a bathroom and started vomiting into the toilet, throwing up his entire breakfast and dinner in the process. The nausea was overwhelming, his entire body trembling as he heaved into the porcelain. Sweat dripped down his forehead as he gasped for breath, his vision blurred as he struggled to regain control of his body.

James entered the bathroom, concern evident on his face. “Man, we need to get you to a doctor. This isn’t normal.”

“No, no. We have the competition in a few minutes. I’m not letting this belly stop me from winning a medal.” choked out Adam between heaves. He wiped his mouth with the back of his hand, his face flushed and sweaty. The nausea had slightly subsided, but his stomach still felt tight and uncomfortable. The weight of his swollen belly pressed down on him. “Just give me… a few minutes to… feel better.”

James nodded, running away while Adam struggled to steady himself. He struggled to his feet, one hand steadied against the wall for support. The extra weight of his belly made even standing up a challenge, making him groan as he felt his lower back strain under the unfamiliar burden. Then, James returned with Adam’s bag. “Here, put these on. Coach says we should get going if you insist on not going to the hospital.

Adam ignored James’ comment about the hospital, focusing on the competition ahead. He splashed water on his face, washing his mouth and trying to forget about the nausea. Adam struggled out of his wet swimsuit, his swollen belly making it difficult to bend over or move as gracefully as he used to. He was so entranced by the struggles of this strange situation that he didn’t mind James staring at him all along, observing everything in his naked form.

He pulled on the sweatpants, but the waistband struggled to accommodate his expanded belly, forcing him to leave it below the swell, right above his manhood. Adam winced as he finally managed to get the pants on, the waistband cutting into his lower abdomen as it struggled to contain the new girth of his waist. The shirt wasn’t much better. What should have been a loose, comfortable fit was not tight and restrictive, the fabric clinging to the contours of his swollen abdomen. The hem barely reached the top of his sweatpants, making Adam tug at the shirt, trying to make it cover more, but it was no use—it was simply too small to accommodate his new size.

“This is ridiculous,” Adam muttered, frustration creeping into his voice as he looked at himself in the mirror. Even with the clothes on, he realized his whole body seemed different. His pecs were fuller, almost as if they had started to grow along with his belly. His thighs, once lean and muscular, now seemed thicker, more rounded, stretching the fabric of his sweatpants.

“Adam, we gotta go if we don’t want to miss the race,” James said, placing his hand on Adam’s shoulder.

“Sure,” Adam responded with a nod, taking a deep breath before coming out of the bathroom with James. Gathered around the bathroom waiting for him were paparazzi with flashing cameras pointed at the swimmers as they walked out of the bathroom.

“Adam! Adam! Can you say anything about your recent weight gain and how it will affect you during the race?” asked a reporter.

“Do you discourage other athletes from swimming in the Seine for the duration of the games?”

“Are you going to bow out and allow your teammates to have a more fit competitor for the event?” Adam fought his way through the crowd of cameras as he held his stomach. He hadn’t realized it before in his rushed state to the toilet, but he couldn’t properly walk and was forced to waddle thanks to his gravid belly.

“Out of his way! We have to get to the race!” yelled James as some security came over and pulled the paparazzi back. Adam groaned as he felt another wave of discomfort wash over him and his belly. He grabbed onto James’ shoulder and hunched over in pain while they walked away towards the event. Each step was a challenge. His belly, now an undeniable presence, swayed with each step, pulling at his lower back and making it difficult to maintain his usual stride.

“James, something is wrong. I don’t know what’s happening.” Adam started sweating and panting as James wrapped his arm around him. The strange tightness in his abdomen had intensified, becoming a constant, almost oppressive pressure that seemed to grow stronger with each passing minute.

“No shit, but you don’t wanna go to the hospital.” James lugged Adam away towards the massive swimming pools but failed to look down at his friend going through another transformation. Adam’s discomfort was becoming unbearable, but he gritted his teeth and kept moving forward. They had to get to the competition.

Adam shut his eyes tight as his belly swelled out an inch in every direction again. His skin tightened with each step he took as he inflated bigger and bigger like a balloon. His body lost more of its toned, athletic muscles as his defined muscles became clouded with fat. This was especially true for his pecs. While he had gotten a slightly puffier chest when he first grew his belly, now they seemed to sprout out of him like two fluffy pillows, the fabric of his shirt tightening as his chest swelled. However, these two pillows were being weighed down heavily as Adam’s nipples, usually small and flat against his skin, became erect and pointed directly at the ground, also becoming more sensitive.

Adam shifted uncomfortably, trying to adjust the collar of his shirt, but it was no use. His chest was growing too quickly, the once loose t-shirt now straining across the expanding flesh. He could feel his pecs becoming rounder and heavier, each step causing them to bounce slightly against the fabric. The tightness in his shirt was becoming unbearable, the material pulling taut over his chest, the seams creaking with the strain.

As his pecs grew over his belly, Adam felt the pressure in his abdomen intensify, the bloated sensation growing more pronounced as his belly began to swell in all directions. The once small, basketball-sized bump was expanding rapidly, pushing outward and upward, the skin stretched to its limits. The lower hem of his shirt, which had already been struggling to cover his growing belly, was now riding up, exposing the pale, taut skin of his abdomen as it swelled larger and larger.

The growth was relentless. Adam could feel his belly expanding, the pressure inside him becoming almost unbearable as his abdomen grew rounder, fuller. It was no longer just a bump—it was a massive, beach ball-sized dome that jutted out in front of him, pulling at his lower back and making it impossible to stand up straight. He could hardly walk with the huge orb growing in front of him. Stretch marks formed on the side of his body as he continued to grow. He could almost hear his skin stretching as he tried to hide the discomfort from James to avoid the hospital topic again.

James, still unaware of the full extent of Adam’s transformation, tightened his grip, helping him stay upright as they walked. “Just a little farther,” James encouraged him, his focus on the pool ahead.

A new sensation hit Adam when he felt a cool touch on his upper thigh. He couldn’t see it, but his perfect bubble butt was becoming round and wide. Adam had always had a nice perky ass, but now his cheeks were growing fat and wobbly as the lower halves of them bulged inside his sweatpants, which strained to contain the increasing mass. Adam’s hips, once lean and narrow, were beginning to thicken, the muscles expanding to accommodate the added weight. He could feel his thighs thickening as well, the once smooth and defined muscles becoming softer, more rounded. The seams of his sweats, already under strain from his expanding belly, were beginning to creak ominously, the fabric pulled tight across his growing hips, butt, and thighs.

Hobbling over to the U.K. team, Adam immediately flopped himself down onto the bench and groaned in pain as his hand rubbed his beach ball-sized belly, so big that he could barely reach the furthest point on it; the skin stretched taut and shiny. The lower hem of his shirt had ridden up completely, leaving his swollen abdomen fully exposed, the tight skin gleaming in the overhead lights, his once innie belly button on display as a full blown outie now.

“Did it get…bigger?” asked James, looking at Adam’s dome. The belly covered Adam’s entire lap as he sat on the bench, and his bulging pecs laid nicely on the round belly, pulling the fabric of his shirt taut. His nipples, now larger and more prominent, pressed against the strained fabric.

“Maybe a little,” said Adam in between pants. Before anyone could say anything, an announcer came over the loudspeaker with a message.

“Olympians, we will be beginning the men’s swimming relay in 5 minutes.” Adam stared at his belly, which looked to be as big as half his body, then started to stand. As he heaved himself up, he heard a loud ripping sound. The seam at the back of his sweatpants had finally given way, the fabric tearing around his swollen glutes. Adam grimaced, but there was nothing he could do about it now. His entire body was swollen and uncomfortable, the weight of his belly, chest, and glutes pulling at his muscles and making it nearly impossible for him to lift himself off the bench.

“We need to get you changed,” James said, his voice filled with concern. “Or you shouldn’t compete at all!”

“You heard him. Let’s go!” said Adam through some groans, ignoring James’ concerned comments as he started struggling to take his clothes off.

With James’s help, Adam began to peel off his clothes, but it was a struggle. The shirt, already too tight, clung to his swollen chest and belly, the fabric bunching up and refusing to budge. James had to gently tug it over Adam’s head, careful not to hurt him as he maneuvered the shirt over his swollen pecs. When the shirt finally came off, Adam’s chest was fully exposed, the round, heavy muscles hanging slightly lower than they had before, his nipples larger and more sensitive than ever.

Next came the sweats, which were even more of a challenge. The waistband was stretched to its limits, the elastic band digging into the soft flesh of his hips. James carefully worked the sweatpants down over Adam’s hips and thighs, the fabric straining with every movement. As the pants finally came off, Adam’s glutes were fully revealed—round, full, and straining against the seams of his underwear, which had somehow managed to stay intact despite the growth.

James handed Adam his competition swimwear, a tight-fitting suit that was meant to streamline his body in the water. But as Adam tried to pull it on, it became clear that it wasn’t going to fit the way it used to. The material, designed to cling to his body like a second skin, now struggled to contain the massive bulk of his lower body. Every movement was a challenge, the weight of his belly pulling at his back, his chest and glutes adding to the strain. But somehow, with James’s help, he managed to get the suit on, though it was far from comfortable.

“Adam, you need to go to the hos—”

“It’s just a bit of indigestion. Let’s go.” Adam cut James off and waddled toward the pool. Still determined to compete in the race despite his massive belly.

Adam’s gait was slow and awkward, his body swaying with each step. His belly was so large that it forced him to waddle, his hips and fat ass swaying side to side as he struggled to maintain his balance. One hand was pressed firmly against the small of his back, the added weight pulling at his spine and making it difficult to stand up straight. His chest bounced slightly with each step, a strange sensation tingling within.

“No reason to worry,” he said to himself as he felt something shifting inside his belly, making him rub his belly in small circles. He tried to stay cool and focused on the race, but the strange fluttering intensified. The only thing he failed to realize was that his indigestion was actually the first flutters of kicks from his many sons in his new womb.
