#108 of Transformation Stories

Summer is in full swing, so let's celebrate not just with transformation and muscle growth, but a story that takes place on the beach! This commission for Rocker checks all the boxes.

In this story of good intentions gone wrong, a young wolf by the name of Rock decides to finally take on the weight rack at the infamous Muscle Beach. When he finds a face friendly enough to chat with, he finds that someone in the outdoor gym is offering up a new, temporary steroid that offers impossibly quick results...but there's no way to know how long they'll last.

Desperate to make quick gains, Rock buys the last bottle and consumes it, only to find the immediate results promise are just that: he barely has time to find a changing tent before he's bursting out of his clothes and hulking his way into a new, incredible body!

With newfound confidence and size, he meets a young woman named Sandra and strikes up a conversation. She's eager to play a round of volleyball with him, but how will he adjust to his new, powerful body?

It didn't matter how nice they were under the surface: approaching the other furs at the Muscle Beach fitness center was intimidating.

There were plenty of people who would vouch for them, and given that it was an outdoor gym with no proper walls, you could see the truth for yourself: There was indeed some competition between the stronger lifters, but there was also an atmosphere of support as dedicated athletes cheered each other on in the quest to make greater gains.

Their bodies were still a point of contention for Rock, who watched from the sidelines and kicked his claws through the sand, too nervous to actually walk through the gates and take his place on one of the benches.

Just getting close enough to see them took courage, in his own mind.

"You're never gonna put any muscle on that frame if you just keep looking from the sidelines, kid."

It was only a matter of time before someone pointed out his reluctance, and after visiting the beach for over a week without doing more than drawing circles in the sand with the tip of his tail, it was a tall, thick stallion that finally addressed him from the edges of the concrete.

He was still curling dumbbells up to his chest and flexing his biceps as he carried on the conversation. "I already know that," Rock told him, "But it's always so crowded in there, and I wouldn't even know where to start!"

" This is where I started," the horse confessed, demonstrating perfect form on his next bicep curl and pumping his arm out to look like a small mountain. "Began with the basics, and I'm still doing 'em. If I were you, I'd go down to the low end of the rack, pick up a few of these and start with some curls."

Impatience and uncertainty were two of the biggest things that kept furs from achieving their desired results in the gym, and unfortunately for Rock, he was ripe with both of those, but especially the latter.

"That's not all I have to do, though...is it?"

"Of course not," the stallion confirmed. "But it is one of the best places to start, and one of the easiest moves you can do."

To have a little encouragement behind him was enough for Rock to look down at his casual outfit and ignore the fact that it would look out of place in a gym. He still wasn't entirely sure of himself, but to have a titan of a horse pushing him along, he could feel his own strength bolstered by the stallion's kind words.

He jogged around the fence and through the front gate, and was greeted with a sea of thick, muscular bodies, each one straining as they worked toward a common goal of self-improvement.

Unable to handle that just yet, he kept jogging right to the dumbbell rack and moved further down the line, until he started seeing dumbbells with single digits.

"...15? I can handle 15, I think," he estimated, having no previous experience to measure his strength against. He lifted the weights from the rack and found they were lighter than he expected, but he was only carrying them: he wasn't lifting them yet. "So, how long have you been doing this for, anyway?"

The stallion's lips curled with pride. "About 20 years."

Rock was just starting his first curl ever when he noticed a strain in his arm. Trying to mimic the equine's form by watching it and copying it, Rock struggled to curl the weight up to his chest without arching his back, and he'd heard time and time again why that was a bad thing.

"...20 years? Really? That's how long it took you to get that body?!"

"No...it took me about nine months to get this body," the horse explained. "But it's taken me a lifetime to maintain it and keep it going at this level. The later you get into your 30's, the harder it gets to keep your muscles looking and working like they used to, unless you want to cheat."

The wolf couldn't imagine waiting a year, six months, or even six weeks for his body to start looking like the paragon of strength that stood next to him. "So, c...cheating, huh?"

Already, the horse was narrowing his gaze down at Rock. "Listen, kid...if you start taking that stuff right out of the gate, you'll never be able to find real strength without it."

Rock was nervous to admit that he was less concerned with his strength, and more with his appearance. He wasn't aware that plenty of bodybuilders were more concerned with their looks than their actual abilities, but when it came down to abusing performance enhancing substances, many of them were in the same boat about it.

He couldn't guess which side the stallion was on, but he'd gotten a quick clue already.

"What if I'm just using it to help out at the beginning? I've heard it can be really hard to get past the first few weeks of a workout routine because of the soreness and exhaustion that comes with it."

"That's just a sign of your body working," he explained. "The feeling of your muscle fiber tearing and expanding as you work isn't pleasant for the first few weeks, no, but once your past it, every day at the gym becomes a thrilling experience. You can watch yourself improving in real time, week after week...I live for it, honestly."

His work ethic was admirable, but Rock didn't have that kind of time, and the stallion could already tell that his canine counterpart was lacking in patience, as well.

"But if you're just trying to impress someone for a day or two...I might know of a guy who can help you out."

Rock blinked. "You're serious? You're gonna tell me just like that?"

"Younger guys these days just don't have the patience like they used to," the stallion muttered, shaking his head as he continued to lift. "But when you give them a sample of what it's like to have the body they'd normally have to work for, it tends to motivate them...certainly more than a speech about working hard does."

Whoever the man was, he'd been around the block enough times to see the desire in Rock's eyes, but not quite the conviction to go after it. That he was willing to help out at all put a smile right back on the wolf's muzzle, but as heavy weights were racked next to him, he could feel a stern glare pointing down at him.

"I'll warn you right now, though...this stuff isn't for the faint of heart, and it isn't gonna work permanently. Sooner or later, you're gonna have to get on that bench and put in some effort like everybody else does...got it?"

Rock nodded firmly. "I got it, sir. I won't let you down!"

"That's what they all say," he grumbled. "Hopefully, you'll be different."

The stallion clearly wasn't getting his hopes up, judging by the change in his demeanor. He made a small, subtle gesture for Rock to follow him as he walked across the gym, waving to everyone he knew...until he came across a creature that didn't turn back to face him, even when it was clear that his presence was felt.

"Is the store open for business?"

"One bottle left. Gonna cost extra."

"I'm not buying," the stallion explained. He grabbed Rock by the shoulder and nudged him forward with the kind of ease that only genuine, earned strength could grant. "This guy is."

A glaring eye of orange looked back over a thick, hulking shoulder. The creature never fully turned back to face Rock, but he was able to capture a roll of the eye from the supplier before he looked away.

"I can see why," the supplier joked and began shuffling through his gym bag. "He needs it more than anyone else you've brought my way, but I don't think he can afford it."

Rock was understandably intimidated by the thick, walking mountains that surrounded him, but that was the first time he'd looked despondent since entering the gym.

The stallion, just wanting to get back to his workout, pulled out his wallet. "I'll front him 25% if he can cover the rest. I've got my own business to attend to."

"You're getting soft, Jesse. Why don't you just tell the kid to buzz off?"

"I'm...I'm standing right here, you know."

It was the first time in many months that Rock had the courage to stand up for himself and speak out. Even Jesse looked nervous when he fished out those words, but his bravado was unwavering.

The supplier finally turned to face him, and for a moment, Rock thought he recognized the man by the orange slash mark through his right eye, but the color of his irises was completely wrong.

"So you do have a pair after all...I was starting to wonder," the man growled lowly and stepped closer to Rock, waiting to see if the wolf would grant him any space.

When Rock stood his ground, he felt a thump against his chest, but it wasn't a fist or a shove that struck him.

"Only a quarter bottle left, kid. I've been rationing this stuff out like crazy to try and keep my customers happy."

Jesse tilted his head in surprise. "You're not gonna charge him full price, then?"

"I just need enough for a ride home. Twenty bucks should cover it."

Rock was never so quick to fish out his wallet, and his trembling paws scarcely had time to steady it before he was throwing money over. The supplier rapidly grabbed the bill and looked around, making sure that he wouldn't lose his membership over the obvious transaction...and just that quickly, he was headed for the gates.

"Uhm...a-any advice?" Rock called after him.

"Workout more often," he called back, his voice dry. "And only drink the whole thing at once if you're planning on fighting a giant!"

Even if he ended up with the results that he'd hoped for, Rock didn't plan on fighting anyone once he was transformed. He was just hoping to look more like the stallion that he'd met, without having to back up the results to anyone else.

He didn't know if he'd be so lucky, but he couldn't believe that it was really as simple as taking a drink from the bottle.

"Who, uh...who was that guy?" Rock asked.

"Some dude who started showing up here a few weeks ago. Puts most people to shame with his lifts, but he just seems angry about not being strong enough. Still refuses to drink the stuff he's selling, though, so I guess I admire his honest effort."

"Seemed familiar," the wolf admitted, but with that, he shrugged. "Must just be a coincidence."

"Guess so. You gonna get back to lifting with me, or are you just gonna take that...into..."

Before Jesse could coax Rock back over to the barbells, the wolf was already hurrying to the nearest public changing room that he could find.

**

Rock made just enough time to sneak by one of the surf shops on the way to the bathroom, and fortune smiled on him, leaving him just enough money in his pocket to afford a swimsuit that was a size up.

The only thing they had left in that price range was a speedo, and he wasn't feeling up to wearing it right at that moment, but as he looked at the fluid swirling around in the old sports drink bottle, he honestly believed that he'd made the right decision.

"If I just get to live like this for one day...even one hour , I bet that's just the motivation I need to really get in the gym and start working hard," he explained it out loud, somehow believing that telling himself that fact would make it more likely to come true. "Chug this, enjoy being a beast for a day, and then use those memories to fuel your success!"

Just holding the solution in his paws was pumping him up, but as he stared into the old, rusted mirror of the public changing room, he couldn't help feeling like he was bidding goodbye to all of the things that used to hold him back. His pawtips weren't trembling anymore when they unscrewed the cap of the bottle, and he didn't feel nervous about gulping down the whole thing, even though he'd gotten it from the shadiest source possible.

He should have been terrified of the potential ramifications, but instead, he was grinning from ear to ear as he slammed the bottle down with a satisfying ka-tunk.

"I forgot to ask about side effects. Shit."

He immediately fell to his knees and wrapped his arms around his midsection, clenching his stomach within seconds of swallowing. The compressed muscle cramps and pains of thousands of exercises were all taking place within a matter of seconds, and he never thought to ask what that would feel like.

He'd been punched in the stomach before; this was closer to being backed into by a car.

"Oooooh man, this w-was not a good idea," he groaned as he slammed a fist on the ground, only to feel more of the floor than he could with his palm earlier. His flesh was growing so rapidly that it frightened him, and next to his head, his paws were already looking massive as they pushed his body up from the floor. "W-woah, shit!"

With more mass and more power, Rock threw himself back so hard that he almost knocked over the rickety walls of the old, aging bathroom stall behind him. It just did enough to cushion him as he tried to stand upright, but the weight of his arms kept pulling him forward.

He wouldn't have believed that they were as large as they appeared if he turned and looked in the mirror. He had to gaze down at them himself and see the thickness of his muscles up close...and that was an easy task; there was no getting away from them, anymore. His pectorals were starting to follow close behind, but with the arms rushing out ahead, his chest was nearly lost in the mass of his biceps as they spilled over the front of his torso.

The young wolf immediately became fearful of just how well the juice was working, but he had trouble vocalizing that fear; at first he thought he was just falling prey to the testosterone-fueled stubbornness that was flooding through his body, but truth be told, even his vocal chords were starting to change, reflecting the larger, thicker mass that was coming from his sprawling body.

When he finally had a chest and shoulders broad enough to support the giant arms he'd been blessed with, Rock felt the ground getting further away; this serum did not skip leg day, and even through a coat of plentiful fur, veins throbbed up to the surface of his flesh and revealed the power that surged through his entire body.

"It hurts...it...it burns, but something about it feels s-so good...just seeing myself this way...f-feels awesome!" he started cheering himself on as he flexed. That quick flexion was the closest he'd gotten to a real workout all day, but the forbidden product that he'd taken responded to it immediately, as even a brief curl of the bicep caused it to rise and peak like a mountain pushed up from the depths of a valley.

If he wasn't the one in charge of those muscles, he would have been terrified of them, but he didn't realize that he only changing on the outside, while the goofy, clumsy wolf he was on the inside remained.

If not for that fact, he would have been arrogant about the fact that his cock was growing along with the rest of his body: even the tiny muscles in the shaft of his length were subject to the transformative juices, and suddenly, his hasty decision to grab nothing more than a speedo left him nervous to leave the changing room.

"No...y-you've come this far," he murmured. "You put that damn thing on, get out there, strut your stuff, and just see where that takes you."

He was still Rock, and that meant that he still had some issues with his confidence...but there was no denying that he'd been given a brief confidence booster by the serum he'd ingested.

He was eager to put it to the test.

**

The beach wasn't the favorite hangout of most introverts, and before that afternoon, Rock only ever watched the sand and the ocean from a distance, feeling awkward about wading through the crowds of sunbathers in order to get anywhere close to the water.

He didn't know if he was supposed to walk a certain way, now that muscles were rippling through his fur and leaving his thighs as thick and wide as an average torso, but he felt as though everyone with the kind of musculature he'd just achieved had a certain swagger to their step.

Whether that came from the natural bulk, or from an attempt to get people to look, he wasn't sure...and his own version of it was every bit as clumsy as the man behind the mask.

"Let's see...just step around the corner," he whispered to himself, as he slipped past the brick wall that divided the men's and women's changing stalls. "There's people wearing way less than your speedo; don't even think about anyone looking at you. Just step right over to the beach, normal footsteps, stop talking to yourself..."

His voice carried a little further than it used to with such powerful lungs behind the landscape of his chest, but he managed to corral his inner voice before too many of the teenagers hanging around by the water fountains could snicker at him for it. He tried to ignore those quiet, distant chuckles, but they drowned themselves out when everyone gazed upon the source of that voice.

Rock was an impressive specimen, no matter how he decided to walk. His normal gait with his old body was a bit of a casual shuffle, but long, powerful legs decided to carry him down a different path, as if they wanted their new state to be shown off to the world.

That miscommunication with his brain, however, left him stumbling just a bit as he made his way into the sand, toward the volleyball courts.

Just a little further, he thought. Get into the water where it'll be easier to find your legs with no one seeing how off balance you are!

The divots of thousands of pawprints in the sand made for a minefield for someone that wasn't used to their new legs, and being such an impressive specimen backfired on Rock for a moment; every eye on the beach was following him from the changing rooms to the volleyball courts, including some of those actively on the courts.

As an errant ball sailed toward him, heightened senses picked up on the sound of a dozen other furs shouting at him: "Hey, brick house! Hit the ball back over here!"

Thinking fast and wanting to look cool for the crowd, Rock saw a ball knuckling toward him and going for the sand. He hadn't properly tested his new reach, but as far as he could tell, his lengthy arms should have been more than capable of getting to the ball before it hit the ground.

Long enough, they were indeed, but his coordination was completely lacking. Just reaching out and swinging for the ball left him tumbling forward, and as he did a full belly flop into the dunes, the ball slipped between his arms. His chin landed on it as he fell, providing even less cushion than the cozy sand beneath it.

The rest of the crowd was laughing and chuckling at his dizzied expense, but there was one soul kind enough to come over and check on him, as she jogged off the court to fetch the ball herself.

"You don't move so well for a big guy, do you?"

Rock thought he might have been concussed on the volleyball, given the way that it struck his chin. He was dizzied in the sand, leaving him regretful to try and gaze upward, but his ears perked to the sweet sound of a caring voice, and his eyes instinctively followed.

He was immediately rewarded for his efforts, as he looked up to a concerned face. Seeing him conscious brought a smile to her lips, and despite his larger, intimidating size, nothing stopped her from reaching out with a kindly paw to help him up to his feet.

"I wasn't always this big," Rock admitted plainly. "I guess I'm still getting used to it."

She cocked a brow. "Still getting used to it? Not like you get those kinds of muscles overnight..."

"Oh, n-no," Rock agreed, as he took her smaller, dainty paw in his own and slowly climbed out of the sand. "I mean, it...it's my first time being this big...y'know...in my life. That's what I mean."

He was worried that he sounded like a dolt, and sure enough, he was speaking as awkwardly as he walked, but his spirit was kind enough, and she felt that when she helped him up. "I get it. I wasn't always this slim, either, but anything worth having is worth working for, right?"

Rock wasn't the type to ogle someone from a distance, and being up close didn't change that. As much as she was used to being watched by the other guys at the beach, Rock kept his eyes on her own as he towered above her, feeling more comfortable in a body that wasn't truly his own.

"That's right," he nodded, but the inward sting of shame immediately followed his lie. "But even once you've been that way for a while, it takes some getting used to. I can't remember the last time I played volleyball."

"You probably weren't so thick then," she theorized. "You've gotta get used to being agile with all that extra muscle you've packed on!"

She had a point; just hearing it made Rock feel silly for not trying out the special steroids at home so he could get used to the new body.

Thanks to his eager recklessness, he was stuck at the beach with no easy way to get back home, and no more of an outfit to cover himself up than the speedo that was just managing to cover up the whole of his package.

"I guess I haven't really put it all to the test just yet," Rock tried to explain. He didn't like lying, and doing so on the fly was always difficult, but worst of all was the fact that someone had been kind enough to come over and check on him while everyone else continued to snicker, or stare, depending on what part of Rock they appreciated the most. "Got any suggestions for how I should?"

Kind-hearted as she was, the girl wasn't immune to the impressive physique that Rock had been blessed with. Now that he was standing again, her face was level with the hard, chiseled torso that he'd been granted, and if she looked down whatsoever, she couldn't help getting an eyeful of the obvious bulge of his flesh against a skimpy speedo.

"You, uh...uhm."

She trailed off and shyly tucked a lock of brunette hair behind one of her tall, sharp ears. The red vixen smiled nervously as she looked up at Rock, trying to act as though she'd hadn't been distracted by his impressive presence.

"You could come play volleyball with us? There's not too many other ways to test your agility around here, really...but you'd probably be the type to hang out over at Muscle Beach, wouldn't you?"

Rock didn't dare to show his face over there again: Jesse would recognize him in a heartbeat, even with the new, larger physique. "I've been there a few times, yeah," he admitted. "I dunno if I can really play volleyball, though."

"Like, you never have?" she asked.

"Not since high school gym class," Rock explained, preferring to be honest. "Not to mention my audition just went pretty poorly, I'd say!"

It might have been an artificial comfort to start, but with his new body, Rock was able to detach himself from the inward doubts that he so often felt when talking to strangers. For once, he was able to just make conversation with someone, even when he found them attractive, without tripping over his words or questioning his self-worth.

For her part, the vixen was smiling and giggling, as well, finding that Rock was a delight to talk to, now that she'd gotten him started. "Well, you don't have to worry about that! We're just playing for fun."

Before, Rock would have stammered out an awkward compliment about the way that her ruffled bikini top looked like it was a little out of place. He couldn't deny that his eyes had roamed the slim, black fabric of her top and the similarly patterned material below, but he didn't stand there and stare, or linger on the subject.

He just smiled nervously and gave a shrug. "I dunno," he hesitated. " You seem like fun, but there's no way the rest of the gang is as cool as you are."

She cocked a brow and finally gave his stomach a playful, feather-light elbow. "Come on, stranger. We need one more player anyway!"

Was she just flirting with me? He wondered, having seen the hints of a smirk in the corner of her muzzle as she pushed him. What do I do? What do I say?

Since their friendly chat started, it was the first time that he'd been at a loss for words, but he kept going with what worked: just answering as honestly as he could without overanalyzing his thought process.

"I guess I'd hate to leave you hangin'," Rock admitted. "But I'm just gonna be in the way!"

"That's fine!" she called back to him, still walking ahead and quietly hoping that he'd follow. "As long as you stand in the way of the ball, that's good enough for me!"

Rock could have dissected her words, or worried that she only wanted him to come over because they needed a warm body to swing at the ball.

Instead, he was just happy to be invited along, and he took that as a blessing as he awkwardly jogged up to the vixen's side again and walked with her to the court.

"Mind giving me a little coaching first?" he asked, walking in stride with her. "This might be hard to believe, but I wasn't great at gym class, either."

The vixen giggled as she pointed to the net. "See that thing, there?"

"Yeah."

"Go stand on the other side of it with those guys, and try to hit it back at me, cause I'm gonna hit it at you , first."

Rock's lips curled into a smirk all on their own, and his ears stayed perked to the obviously teasing tone in her voice. "Just remember that you asked for it!" he warned her, as he started heading the other way. "Does my new target have a name, by chance?"

"Sandra," she looked back at him through locks that cascaded perfectly over the sides of her muzzle. The hair tie wrapped around her wrist was put to good use as she lifted those tresses up into a long, messy ponytail and jogged into place on the court, keeping her glare focused on him. "And just for that, I'm not gonna go easy on you!"

Though her friends weren't the most talented players in the world, Sandra had some skills on a beach volleyball court, and right as Rock took his place in the back row, he found himself on the other end of a serving assault.

Impressively athletic herself, Sandra jumped into the air and spiked the volleyball across the net, right at the footpaws of Rock's new form. It was a carbon copy of the situation that brought him to the court in the first place, but this time, he was a little more adjusted to his new, longer arms.

Though it was still an awkward tumble forward, Rock dove for the ball as it rocketed toward the ground. He couldn't properly move with the kind of fluidity needed for a softer motion, but the fact that he couldn't get his footing in the sand ended up as his saving grace.

As pawpads threw sand into the air behind him, he clumsily fell forward, causing the ball to bounce off of his arms, rather than being directly struck. Against his thick, hard muscles, that was just enough force to send the ball back up into the air, where his new teammates went for a set, and followed it with a perfect spike.

It was the first time all day they'd been able to counter one of Sandra's serves, and as the rest of his teammates chuckled and cheered, Rock felt a smile crossing his face without him having to think about it or force it for anyone.

He stood up and cheered with his team as the corralled around him, but it was Sandra's expression that worried him the most.

Eyes of soft hazel were lit with a competitive fire that came away as anger at first, but when she felt Rock meeting with her glare, it softened, and she granted him a smirk instead.

"You got lucky that time, big guy!" she called across the court. "Next time, you're going down!"

**

Most men would have been too self-conscious to spend their entire day in a speedo, even when they were in the right place to be wearing one.

Rock put himself in that situation, but given the results that came of it, he didn't regret his choice of attire, or taking the steroids that helped him to fill it out.

"So you were really that much of a nerd in high school?" Sandra asked.

They were sitting away from the court and her friends, after the sun began to set. Across the beach, small bonfires were being started, but the summer warmth was still radiant in the sand, and Rock found enough heat in his soul just by sitting close to his new vulpine companion.

"Yeah...it doesn't feel like that long ago, really," Rock explained. He wanted to tell her the truth about his new body, believing that she wouldn't have warmed up to him so quickly without it, but there would be no way to work it into the conversation, right then. He could only tell little snippets of fact about himself, but thanks to his new muscles, he had the confidence to do that, without any fear of being judged. "But you must have been quite the athlete!"

"I think I'm still pretty good, for what it's worth!" she teased, offering him another playful elbow. Her legs were crossed as she sat next to him by the incoming tides, just far enough down the beach from her friends that they wouldn't be able to eavesdrop on her conversation. "But yes, I was pretty dedicated at my craft. My high school went all the way to state for volleyball, and that got me a full ride to my local college. I actually just finished my degree; this is probably my last vacation for a long, long time."

Rock shook his head. "Being an adult really isn't as bad as everyone makes it out to be. Sometimes, you've got more free time than you know what to do with!"

"You say that like you're so much older, Rock."

"I graduated a couple of years ago. Still been trying to figure out exactly what to do with my life, but I make ends meet, and I get to come to places like this almost whenever I want," he explained. "Some days go a little better than others."

"Nice to know that there's still some things to look forward to when I'm all old and wrinkled like you are," she joked. "And just how does this day rank, as far as your summer is concerned?"

"It didn't start out so great, if I'm being honest-

"I'd prefer you were," she interrupted.

"Well, it's definitely in my top ten, now," he finished his answer. "Hard to believe that the best part of my day was tripping in the sand and almost getting conked out on a volleyball!"

"It's not this moment right now? I guess I'm just chopped liver."

Rock flattened his ears and gave her a sideways look. "What's that supposed to mean?"

She giggled. "I'm kidding, dude! Lighten up...I knew what you meant."

It was hard for Rock to relax when he knew what he'd done was a temporary change, and he had no idea when it would come to an end. At any point in time, his muscles could deflate, and he could be sitting in an oversized speedo next to one of the nicest girls he'd ever met.

He didn't want to ask if she'd still find him so interesting without them.

"Sorry, I...I guess I'm not used to a girl having such a sense of humor! You're a lot of fun to be around, Sandra."

This time, her ears went slightly flat. Her expression was demure as she tried to hide the bashful streak he'd stirred awake inside of her. "I'm not that much fun," she argued. "I'm just a girl who happens to like beach volleyball, and I was in the right place at the right time."

"And I'm just a klutz who happened to trip over your volleyball," Rock countered. They were chuckling together as she rested her paw in the sand between them, absently drawing circles in the grains with a claw. "But I'm really glad that I did, Sandra."

"And I'm really glad you decided to join us," she agreed, smiling up at him as the moon began the slow ascent from the edge of the ocean. "I've gotta say, I didn't think someone as...boldly dressed as you are would be so shy and inquisitive. It's a nice change of pace from most of the guys I've ever met."

Rock immediately flushed under his fur. "My outfit got ruined earlier and it was the only thing I could find on short notice," he explained, telling most of the truth. "And it's really, r-really uncomfortable..."

"If it's not too forward of me to say, I can kinda tell that it's uncomfortable, dude."

Just her confirming that she'd looked at his bulge drew a quick pulse from Rock's painfully contained length, but he was much too bashful to act on something like that. He visibly squirmed at being called out, but even then, he felt a soft brush of pawtips against his right arm.

"Hey, I...I'm sorry. That was probably a bit much," she admitted. "If I was forced to go out in a string bikini and a thong, I'd probably be a little self-conscious, too."

"I'm...heh. I'm just glad it didn't scare you off, honestly," Rock confessed. "Every time I breathe I worry that something's gonna pop out."

"Well, you can't use that excuse if it happens, now," Sandra teased him again. "I'll know you were just looking for a reason to whip it out!"

Rock's ears were nearly melted to the back of his head. "I would nev-...oh. You're messing with me again, aren't you?"

"Mostly," she replied. "I'm just glad you're starting to catch on."

"I can be a bit of a slow learner...but I think I'm starting to figure it out, if you're willing to be patient?"

She pressed a kiss into the fluff upon his cheek, and as she did, he brought his larger paw to rest over her own, curling his digits over hers in the slowly cooling sand.

"I've got all summer," Sandra whispered to him. "That is...if you'd like to spend it with me."

Rock didn't know how long he'd be able to keep his new body. He wasn't sure what Sandra would say or do when she saw the truth, but he'd been himself from the inside that day, and that person was who she was flirting with, right then.

He squeezed her small, tender digits in his own and nodded. "Just as long as I get to change clothes once in a while," he joked.

She immediately giggled. "See? You're catching on already!" she assured him, though her eyes drifted back to his thighs as she rested her cheek against his own. "But...I suppose you can go put some shorts on, yes...as long as you save the speedo for later."

She wouldn't tell him right then if she was serious about the speedo or not. It would be up to him to figure that out, but he couldn't think of a better way to spend the summer months.
