Always one to care for her team, Gou Matsuoka gives Haruka, the renown freestyle swimmer, a little drink after a long day of training. But was this really just a kind and simple gift? Or will Haruka be faced with some other enhancements to his swimming abilities?

*****************************

The sounds of splashing water filled the Iwatobi High School swimming pool as Haruka Nanase was once again practicing after hours. He never tired of being in the water. The water was his home no matter where he went. His lithe, but muscular body cut through the water as he crossed back and forth along the lanes of the pool. He was timing himself with each pass, trying to beat his own time. He always strived to get better and better.

Meanwhile, Gou Matsuoka was secretly watching from the entrance. She was entranced watching him. She was so glad to be the manager for such an amazingly muscular team. She couldn’t help herself. She loved watching them. She still cared deeply for them, but she could never manage to keep herself from admiring those defined swimmers’ muscles whenever they were around. Even just thinking about it caused her to blush.

She continued to watch Haruka for a while longer until he finally pulled himself out of the pool. This was her chance. She began to make her way over to him. Haruka was a bit surprised to see her as she drew closer. “Oh! Kou, what are you doing here? I thought you went home with the others.” Gou just shook her head, “You know a good manager doesn’t leave until the last swimmer does. And I should ask the same of you. You need to stop staying after practice. I know swimming’s important to you, but you shouldn’t overdo it. Practicing is one thing, but over-practicing is another.”

Haruka just turned averted his gaze back down towards the edge of the pool, “Yeah, I know. But I just love being in the water.” He draped his towel over his shoulders and Gou couldn’t help but blush as she realized he was just standing there in his swimsuit, his muscles on full display. She thought she had prepared herself, but apparently not. “A-Anyway,” she said as she tried to regain her composure, “you need to take care of your body. Here, I got you something.”

She began to rummage through her bag and pulled out a small bottle and tossed it over to Haruka. He caught the bottle with ease and flipped it around in his hands to read the label, “What is this?” Gou grinned widely, “It’s a new protein drink. I picked up a few of them at the convenience store the other day. I already gave them to the other team, but I had to wait for you to finally get out of the pool to give you yours.” Haruka turned the bottle around and read the label. It was certainly a protein drink, not one that he had seen before. “Uh...thanks, Kou...I guess.”

Gou sighed, “Just drink it. It’s good for you. Helps you regain energy and stamina. It’ll even help make you stronger too. Think of it as another form of training.” Haruka didn’t seem too convinced. He looked up at Gou who nodded earnestly and then back down at the bottle. He sighed and tore the cap off and took a sip; it actually tasted pretty good. He quickly downed the rest of the bottle and tossed the empty container back at Gou who fumbled it back and forth a bit before finally catching it. “There. Happy now? Can I just got back to swimming now?” Gou shook her head, “No way. I told you you need rest. Plus I read that this protein drink works best when drunk at the end of a workout, not in the middle so you better get going before I have you kicked out.”

Haruka just groaned and gripped the towel around his neck, “Alright, fine. I guess I’ll see you tomorrow then. Thanks for the protein drink. It actually was pretty good.” Gou smiled happily and watched as Haruka trudged his way to the showers. She stayed back for a little bit, mainly to calm herself, but also to make sure Haruka didn’t try to come back after he thought she left. She sat back on the bleachers and giggled to herself, anxious for the next day to come.

Haruka made his way into the changing rooms and got back into his school uniform. Gou might have been onto something with that protein drink. He did actually feel more energetic. He wanted to swim some more, but he wasn’t going to deal with Gou’s anger. He just signed and headed home, his thoughts wandering back to swimming like always. It was always on his mind. He couldn’t wait to get home and take a bath.

About an hour or so later, he finally got home and immediately went into the bathroom and began to prepare a bath. He preferred them over showering since he could just soak and be in the water. Once the bath had filled enough, he slipped himself in, still wearing his swim trunks, and sighed as he felt the warm water cover his body. The warmth pierced deep into his muscles and began to wash away the tension and stress he put on them from the extra practice. He sunk deeper into the bath, briefly dunking his head beneath the water and resurfacing.

Time passed him by as he relaxed in the bath. He had long since cleaned himself of the dirt and grime of the day; simply enjoying the water. He could feel the water cooling off, though, and he began to pull himself out of the water. As soon as his hands hit the sides of the tub, he felt them cramp up painfully and his arms buckled, sending him back into the tub. He coughed and sputtered as he pulled his head back out of the water and looked down at his arms. Maybe Gou was right. Maybe he did overwork himself today. His arms were quivering and he could barely move them.

Suddenly Haruka’s entire body cramped and seized up. He grunted as pain wracked his entire body. It was like he was being torn apart limb from limb. Did he really damage his body this much? He closed his eyes tightly and let out a low, guttural groan that echoed around the bathroom. He could feel his body rise up as it tensed, pushing his chest out of the water.

After a few torturous seconds, haruka’s body finally relaxed and he collapsed back into the cold water. He panted, completely exhausted now from the ordeal. He didn’t dare move a muscle now. He just stared down at himself beneath the rippling water. He watched his chest rise and fall with each breath, trying to figure out what he was going to do now. Was he going to be stuck in this tub for the rest of the night?

As his mind raced frantically through his options, he began to feel a warm sensation spreading across his muscles. It was like the warm light of the sun was building up inside of him. He could feel the lingering pain fade away as his muscles relaxed. He decided to chance it and pulled his arms up out of the water and looked down at them. They were still quivering, but something seemed...off about them now. They looked swollen and flushing red. He flexed his hands and watched the muscles of his forearms flex underneath his skin. The muscles writhed and tensed with each movement, the warm heat growing stronger.

Haruka looked down at the rest of his body. Everything was flushed read just like his arms. He was baffled. The water had long since gotten cold, there should be no way his body would be turning red. The heat was starting to become unbearable as well. Just what was going on?

The heat suddenly skyrocketed across his body. He moaned and clenched his hands tightly. It was like his body was on fire, but despite the pain it actually felt...good. His muscles never felt so relaxed in his life! The heat was piercing so deep into his muscles that they felt weightless. Steam was starting to rise from the water once again as his body started to reheat the water around it. Haruka looked down at himself again and curiously flexed his arm. The bicep rose up from his arm like normal, but it felt like he wasn’t flexing at all. He tensed the muscle harder, trying to get it to actually feel like he was flexing. The bicep rose up a little further, but he still never felt that sensation that was supposed to come.

He gave up and let his arm sink back into the now hot water. As soon as it did, the cramps seized his body once again. He gasped in shock as the pain coursed through his body again. It was the strangest sensation, there was the pain from the cramps coupled with the pleasurable burn all at the same time. His mind couldn’t figure out how to think anymore. He could only gasp for air as every muscle clenched to the max while still refusing to feel like they were flexed at all. He could see his muscles pulsing beneath his pink-hued skin now, threatening to burst from his body.

A soft grinding sound filled his ears after a few seconds and he looked around to see where it was coming from. Eventually he found the source coming from beneath the rippling water below: his own body was groaning as it forced its muscles into a bigger and bigger pump. He was literally growing before his eyes!

Haruka watched as his pecs pushed outward centimeter by centimeter, firming up and rounding up into firm mounds of muscle. He looked down to see his shoulders pushing outwards, developing into defined orbs as they split into three distinctive heads. The rest of his arms were under the rippling water, making vision difficult, but he could tell they were thickening alongside the rest of him. He looked down towards his feet, only the toes poking out of the water, but they too were slowly rising upwards towards the edge of the tub.

He was starting to hyperventilate now, the growth picking up pace as his muscles flexed harder and harder. The pain from earlier had lessened to a dull throb, allowing him to feel every one of his muscles tingling as they slowly grew. It felt good; like his entire body was being massaged by a soft static. He let out a content moan and watched his body grow.

His pecs were starting to obstruct his view of his lower body now. It wasn’t much yet, but it was clear he had a firm set of pecs now. He could feel his shoulders bump up against the sides of the tub now as he occasionally jerked to the side by a random spasm. He cried out in pain and his head whipped backwards as another massive spasm hit his body. His eyes clenched shut as he waited for the pain to subside.

Once the spasm subsided, he looked down at himself and was shocked to see his muscles had exploded him size. He had to of gained a good five inches of girth to his pecs alone. They looked like soccer balls had been forced beneath his skin. His shoulders were now firmly pressed up against the sides of the tub, each one the size of a bowling ball. His body had also been forced to rise up out of the water and he could see further down his torso to see six large abdominals rising like loaves of bread from his stomach. He could see his arms better now too. His biceps alone looked as large as softballs. No doubt the accompanying triceps below them would accentuate them whenever he flexed his arms.

As the pain subsided again, the tingling returned, this time stronger. He would have loved to sink back into the water and let the wonderful sensation wash across his body, but his arms were still locked in place. A few, slow rips and tears were starting to emit from the water as his his thighs began to grow too large for his swim trunks. Even the stretchy lycra material could not handle the pure mass that was crowding onto his frame. He looked down towards his legs and could just manage to see the rips growing larger and longer up his thigh.

Another spasm coursed through his body, this time he consciously endured the pain to watch its effect on his body. It was an amazing sight to behold as his muscles seemed to erupt beneath his skin. His pecs seemed to double in size, completely blocking his view of his abs. It was a shame as he would have been able to witness his abs split further into an eight pack, each one as big as the thick hands holding up his swelling body beneath the water. His lats flared out as his back bulked up into a canyon of mass.

The slow ripping sounds from earlier had picked up as well as he watched the legs of his trunks vanish into a spray of tiny pieces of confetti that floated up to the top of the water. His feet were also towering up from the water, his toes now peaking above the edge of the tub, clenching down around it and cracking the fiberglass. He could hear the tub creaking and groaning now as it fought to contain his bulk.

Once again the spasm subsided and Haruka’s body was bathed in a glorious ecstasy as the electric massage returned at full force. He couldn’t help but moan at the sensation. Another minute of slow, mind-numbing growth passed and finally both the cramping and heat started to dissipate. Haruka would have collapsed back into the water as his body was allowed to relax, but his shoulders were firmly wedged on either side of the tub. He had to wiggle himself gingerly until he was able to work his thick arm up out of the tub. His other arm followed suit and he slammed his massive hands down onto the sides of the tub and launched him out of the water.

He landed with a heavy thud that shook the entire room and gazed down at himself in awe. He was huge now. He held his hands out in front of him, his skin returning to his normal pale complection. His hands were now as large as baseball mitts, his fingers like meaty sausages. He clenched and unclenched his arms, his thick forearms bulging up under his skin. He couldn’t see anything else past his pecs so he ran to the mirror on the back of the bathroom door.

What looked back at him was a massive hulk of a man, easily three or four feet wide at the shoulder and covered from head to toe with muscle. He experimentally flexed his arms, the biceps surging up beyond the size of his head while his triceps dipped down below then. Even unflexed his lats flared out behind his arms, but as he flexed, they swung out like the wings of an eagle. He turned to the side and flexed his tricep, the muscle shapeshifting into a clear horseshoe. He then turned back to the front and flexed his pecs, bouncing each one up and down in tandem. They looked like two basketballs being dribbled down a court. He couldn’t help but grin at the comparison.

He ran his hand down his torso, sliding them across his firm abs. His fingers bounced up and down as they hit each muscular mound. They were deep too. He curiously stuck a finger down between them and could get all the way up to his second knuckle. His waist had remained mostly unchanged. Maybe a little bit thicker, but it was nothing compared to how dramatically the rest of him had changed. The thin waist coupled with his massive wingspan gave him a taper far beyond the V that many bodybuilders sought.

Haruka had to take a few steps backwards to see his legs. They were so thick now that they rubbed up against each other as he walked. His thighs had developed into three distinct, teardrop-shaped groups that quivered with each step. His calves looked like footballs had been shoved beneath his skin, keeping in proportion with his colossal thighs. His swim trunks were a thing of the past, having shredded to the point that they now looked like a speedo clinging for dear life to the only portion of his body that remained relatively unchanged. The best of all were his feet, though. Haruka had some pretty large feet originally, perfect for a swimmer, but now he had two thick, muscular flippers supporting his body. He lifted one foot up and wiggled the toes of his foot. He guessed they had to be somewhere around a size 20 or more by now.

He slammed his foot back down onto the ground, the room quaking again, and he smiled as he explored the rest of his body. He had no clue what had just happened to him, but he couldn’t exactly complain. He even seemed to gain an inch or two in height. He just looked himself over as he turned back to face himself in the mirror and pulled himself into a most muscular, veins covering every inch of his body. He was pleasantly surprised to see his head was swallowed by his massive pecs, shoulders, and traps and flexed harder still, the muscle bulging up to their fullest pump. He let out a low grunt that resonated deep in his chest as he stood back up and looked over himself one last time. Tomorrow was going to be fun seeing just how fast he was going to be in the water.
