Lurker smiled as they looked at the card in their hands, turning it over again in his paws as he rode the bus home. His tail twitched a little in excitement, and a little in discomfort with the chair; they were stuck using one that didn't have room for it, although being a smaller mouse at least meant he had space to rest it on his lap. He looked back up, watching the windows, before returning the card to their shirt pocket when he saw their stop approach.

He waved to the driver as they stepped off, before jogging toward their apartment. It took a moment for Lurker to fish the fish out, nearly dropping the card; they fumbled to make sure he didn't lose it, keeping it firmly in their grip as they entered, looking around for his partner. He didn't need to wait for long, as the pale-furred mouse was soon jumped on by Sadie.

"Hi, Lurker! How was work?" it asked, holding him in a hug. He blushed, nuzzling their cheek against it as they hugged back, before pulling away from the fat, purple feline so he could settle in a chair.

"It was good! Work itself was alright, but look at this." they said, pulling the card out and setting it onto the table. Sadie joined him, its belly pressing against the bottom edge as it turned the card in its paws.

"Blazing Gym, six month membership?" it asked, before looking back up. "Was this a gift at work?"

"Yeah!" Lurker replied, enthusiasm in their voice as they took the card back. "It just opened, and one of my coworkers got me this as a gift." He pulled a sleeve up, smile fading a little as they showed the somewhat weak muscles of his arm. "He, ah, said it would help me with carrying stuff around..."

Sadie giggled a little, before leaning over to kiss his cheek. "Hey, you're pretty either way!" it said, to which Lurker nodded in agreement. "Although, I wouldn't mind if you were stronger..."

Now it was Lurker's turn to let out a small laugh, setting the card down onto a nearby counter. "Well, we'll see once the weekend comes! Gotta wait a few days, plus how long it takes to get stronger." he smiled, pulling the chair away as walking around to nuzzle Sadie. "Anyway, how was your day, hon?"

Cat and mouse looked up at the gym building, bright orange and red facade marked by art of stylized flames. Among the flames were figures with various builds, from skinny folk to fat ones to buff ones, all in the process of exercising. The building felt both welcoming and intimidating to Lurker, but as Sadie leaned in to give him another hug and kiss, they felt more at ease.

"You'll be alright on your own, yeah?" it asked him.

He smiled and kissed it back. "I should be, yeah; they'll have a spotter, according to the website. Meet me in an hour?"

"Of course! Love you~" it replied, blowing one last kiss as it wandered off towards a nearby store. The two had agreed that while Lurker tried out the gym, Sadie would pick up some snacks for afterward. Swallowing their fear, Lurker approached the gym, pushing the door open as they stepped inside.

The air was cool, very cool; Lurker guessed that this was a way to keep the patrons from getting too hot. Through a window they could see some folk exercising already, people of various species lifting weights and running on treadmills, a few taking a break to wipe their sweat off. He blushed a little imagining them, but turned back to the desk in the lobby, looking at the receptionist as she spoke with another client.

The smaller fox smiled as she helped the man in front of her register, ears bouncing as she grabbed something from the desk. Lurker settled into one of the soft seats, picking up a leftover fitness guide while they waited. It wasn't entirely clear to him, but it did have some advice on diets for various builds; he wasn't sure how much it was actually useful, but it was enough to keep them occupied while the other person got their own membership sorted.

When his turn came up, he gave a small, polite nod to the fox sitting in front of him. Her red glasses gleamed as she nodded, bright red tufts in her massive ears shaking with every movement. She gave a polite, quick greeting. "Hello! Welcome to Blazing Gym, how may I help you?"

They recognized her species as she spoke, a Braixen; it was a bit unusual to see a Pokémon, but he shrugged it off for now, focusing on their membership. They thought to themself it was perhaps appropriate, at least, that a fire-type work a gym with a fire motif.

"Oh, I got a gift membership, and I figure I wanna try things out and see if I like it here."

The receptionist squinted a little, lifting her glasses up as she took the card and gave it a quick read. Pulling out a small scanner, she ran the card through her computer, beaming when she returned it alongside a small key. "Ah, yeah! Lurker, one special six-month membership, including a private locker. Feel free to use any of our public facilities, including the drink table!"

He smiled, stuffing both the card and key into a pocket. "Thanks. Um, where are the lockers?"

"Just follow the signs once you're in the hall!"

Lurker nodded, before making his way inside. The receptionist was right; it was quite easy to follow the signs to where the locker room was, and although their designated locker was small, it was enough to store his clothes. They did get a little embarrassed when he realized that the locker room was gender-neutral, but after a moment he realized he'd feel embarrassed regardless as they stripped their shirt and pants off in favor of a more athletic set. Still, it was quick, and only two other people saw him changing anyway.

As they looked around the various signs showing different areas - multiple rooms for general exercises, a court for indoor sports, a pool, and more - he realized he wasn't actually sure where to start. They awkwardly stepped into one of the rooms, looking at the various weightlifters showing off their muscles, before hearing someone call out from behind them.

"First time?"

Lurker jumped a little when he turned to see who'd spoken, looking up at a taller man. A fiery mane of red and yellow framed his face, and his shirt, while loose, left little of the Pyroar's bulk to the imagination. He held out a paw to the smaller mouse, giving a firm shake. "Name's Martin."

"Lurker."

"Nice to meet ya!" he smiled, before his phone vibrated and called his attention away. After a moment, he turned back to Lurker. "Looks like my usual exercise partner's a bit busy today. On the plus side, that means I can spot you, show you the ropes."

Lurker blushed again as they admired his firm muscles, watching him as he rested on a bench. As he sat down with him, he looked around the room, unsure what device to use first. "What's good for a beginner?"

"Well, first things first, what do you want here? Gaining weight, getting stronger, larger muscles?" Martin replied, tail lazily swaying behind him. "I can help point you in the right direction, but I need to know where you wanna go, ya know?"

"Right." Lurker said. "Um, how about bigger muscles? Though being stronger sounds good too..."

Martin stood back up, taking the small mouse's hand in his own as he guided him around. Rather than lead them to any specific machine, however, Martin instead brought him to a set of mats on the floor that happened to be free, turning to face them as he spoke. "Right. How about we start with some stuff you don't need a machine for? A few minutes of pushups and squats?"

Lurker nodded along, following the lion's instructions as best they could. After a few minutes of pushups he already was starting to grow a little sweaty and tired, but not enough to stop them from joining in various squats and stretches as well. Soon, the mix of simple exercises and warmups was done, although Lurker needed another minute to recover before they got pulled along to the weights.

"Alright, let's start with something small." Martin said, helping Lurker lie on their back and setting some metal discs onto a bar. As Lurker struggled to lift it, Martin offered support, guiding his arms into a better pose, giving them words of encouragement. Slowly, Lurker found himself doing better, able to lift the weights above themselves, although still not too easily. Some challenge was needed in exercises like this, after all.

Once Lurker ran out of breath, Martin nodded to another person, who handed them a pair of water bottles. "Here, let's take five." he said, before managing to slam half of his bottle in a few seconds. Lurker wordlessly took their own bottle, a bit slower to drink, but finding it helpful and refreshing all the same.

"Alright, anything else?" he asked, looking over the room.

"Well, if you want big and visible muscles, you'll also need to do some cardio," he explained, "so how about some time on the treadmill to finish up this session? If you like it, you can probably focus on specific exercises each day later, or keep up the general stuff."

"Sounds good!" Lurker replied, finishing his bottle. The water itself didn't seem different, but he felt more energized after finishing than they expected; they looked over the decal on it, showing a buff bird woman, before noticing that Martin's had, appropriately for him, a Pyroar. "Can I keep the bottle?" they asked, getting an approving nod from their spotter and trainer.

The treadmill came and went; the two simply ran on them at a low speed, allowing Lurker the chance to get used to it. It took Lurker a bit of convincing from Martin to try running without holding on to the safety bars, but soon enough they were confidently jogging, even turning the speed up slightly before noticing the time.

Back in the locker room, Lurker still felt embarrassed to be switching their clothes around the others; he thought he saw a couple looking at them, although even with more folk in there than last time most weren't paying them any mind. Lurker's own attention was pulled somewhat by looking at his chest; he thought they saw a bit of growth already, running a paw along their abs and noting the slight change in texture, gently poking a slightly swollen chest. For now, though, he dismissed this, eager to meet up with Sadie again.

They were quick to hug it when the two met back up outside, sharing a few nuzzles. Lurker smiled when he saw that it had several bags worth of food, giving a small flex of his arm. "Want me to help?" they asked.

"Yeah, that'd be good." Sadie replied, quickly handing the heavier of its bags over. "Say, you already look a bit stronger. Gym go well?"

"Yeah! I met a guy who helped run me through a few exercises." Lurker said. "In fact, I think I'll go again soon, maybe next week."

Sadie giggled as it nudged them with its elbow, the two heading back to their home. "Hehe, Lurky's gonna get all big and strong, and sweaty..."

--

"Back already?" Martin asked, waving his tail behind him as he looked at the mouse in front of him. He couldn't help but notice they'd grown slightly taller, a little more muscle on their frame. Lurker didn't seem to be aware of his own changes, but then again he wasn't as experienced with bodybuilding, so Martin set that thought aside.

"Yeah! I've been doing a few basic things at home too, situps, stretches..." he smiled, already taking a drink of water. They smiled as the two stepped into the locker room once more, although he was still a bit nervous to strip in front of his friend. "I figure that I might as well make the most of this membership, and having weekly trips works with my job, so..."

Martin nodded, watching the mouse getting dressed, the two returning to the gym room proper. They once more began their warm up stretches, and Martin was pleasantly surprised by how quickly Lurker had improved, his movements more confident, their stamina lasting longer. Of course, they still rested for a few minutes afterward, sitting on a bench and having drinks.

Lurker brushed some of their hair aside, frowning a little when some fell into his face. He looked around, before spotting a woman tying her own hair back and approaching her. "Hey, is it alright if I ask for one of those?" The other woman shrugged, before pulling out a spare.

"Sure, I guess?" She quickly pulled the mouse's blond hair back, tying it into a ponytail behind their head.

"Thank you! I might need to get a trim soon..."

Throughout the exchange, Martin just watched, staying quiet about how Lurker definitely had blue hair when they entered. Soon, the two settled on spending the rest of the session lifting small hand weights; Lurker at first struggled, so Martin helpfully got him a lighter set.

Over their exercises, Lurker noticed their hands feeling more dry than before, despite their exercise working up a sweat otherwise. His claws seemed to poke a bit more into the weights as they set them onto the ground, doing some more stretches to work out his soreness. Still, it felt good; he ran a finger along his muscles while checking their heart rate, and was happy that he could already feel how much he was growing more muscle.

When they returned to the apartment, it was their turn to hug and kiss Sadie; he lifted it up off its paws for a few seconds, before having to set it back down and catch their breath. He blushed when Sadie kissed them, a bright red poking through his fur a little even afterward. Sadie smiled, opening a bag to reveal a small assortment of fruits and snacks.

"I thought since you're gonna be exercising more, you might want some food that's good for muscle!" it said. Lurker smiled as they looked over the selection, before pulling it in for another kiss.

--

Sadie grunted as it moved the apartment couch back, pressing it against the wall. It nodded towards Lurker as the two managed to fully press it against the wall, before turning and settling itself onto the couch, exhausted. Lurker smiled, bringing drinks over for the two of them, and Sadie was quick to have some.

"Thanks for helping with the couch." they said.

Sadie gulped down some more of its drink, spilling a little water onto its chest. "Of... course... how aren't you winded?"

Lurker shrugged, their shirt a little tight against their own chest, two soft mounds gently pressing against it. "I guess my exercise has been helping?" they posited, giggling as they flexed an arm. The muscles bulged out a little, soft pink fur shifting as they highlighted their new muscles; as they took a drink from their own bottle, it was clear to see how their hands were growing dry, hair having faded in favor of gray skin.

Smiling, Lurker stood up again, pulling out a soft mat to lay out on the floor. They giggled a little when they saw Sadie blushing, before realizing their exercise shorts were highlighting their rear; they teasingly wiggled their hips a little, highlighting their cheeks before doing a few more stretches. "Like what you see?" they asked, tail wiggling a little as it shrunk, small tufts of red forming along the base as they started to bend forward to show off further.

"Y-yeah..." Saide replied, leaning forward a little as it watched. It wiped some sweat from its fur, before pulling back against the couch when Lurker turned to face it.

"You know, while I'm waiting for those weights I ordered to arrive..." they said, a sly grin on their face as they approached Sadie. Carefully, they wrapped one arm around its hips, the other gently brushing its chest before firmly grasping its shoulders. In one smooth motion, Lurker soon lifted Sadie up, grunting a little from the strain as they did. Sadie found its face pressing against their shoulder and armpit, kicking a leg a little in surprise. They managed to hold it up for several seconds before conceding and returning it to the couch.

"Alright, maybe I can't quite lift you up yet..." they admitted, wiping their brow as they sat down next to the blushing cat. A sudden thought crossed their mind, and Lurker smiled again when they decided to act on it, exploiting their recent growth spurt to hoist themselves up a bit higher than Sadie and press its face into their armpit. "I know you like this~" they said.

Sadie nodded, affectionately nuzzling against their pit. It felt soft, softer than before, blonde feathers mixed with the old white fur. When it looked at its partner up close like this, it could see how they were changing easily, especially when they took pictures of themself each week to track their gains. It giggled a little, pushing against the arm holding it in place so it could speak again.

"You know, you've been changing a lot recently... I think the gym's been doing something to you." it said, and Lurker nodded.

"Yeah... even if it was just the muscle, there's no way it'd be this fast normally." they replied, giving Sadie a warm smile. "But you know what? I like it! Besides this," they said as they flexed a bicep, "it just feels... good, being taller, more feminine." They smiled, pulling Sadie in for a quick kiss on the lips before stretching out. Another stray thought ran through Lurker's head as they looked down at the yellow feathers growing around their ankles and feet, wiggling a few toes ending in sharper claws.

"You know, my paws are getting kinda sweaty~" they teased, leaving Sadie to cry out in excitement for a moment before it willingly slid off the couch to sit on the mat. Lurker grinned, one foot pressing against its face and the other into its belly, careful not to cut it with the claws. Sadie gave their foot a small kiss, pressing back against it, before Lurker put more pressure on it, watching as the soft cat began to lie down so they could more easily put their claws on it.

"Yeah, I think I can get used to this... think this'll stick around even after the membership runs out?" they asked. Sadie blushed deeply, its response incomprehensible but clearly excited.

--

Lurker smiled as she tied her hair into a ponytail, before turning to look over their face in the mirror. Their lips were starting to harden and stiffen, pushing out into a small beak, but the slow pace of her changes meant that they were stuck in an awkward middle ground for a few days. Still, it felt good, and they smiled as they turned to Martin as he awkwardly waited in the corner.

"Thanks for spotting me again this week." she said, already flexing and stretching a little. Her talons wiggled in her new shoes, and they turned a little to look over themselves. "Remind me to thank that Flareon lady for the outfit advice, too." she added.

"Anytime, Lurker." he replied, stretching his own arms out a little. Her feathers were still growing in, leaving her an odd mix of white, pink and red that had attracted a few odd looks, but that was fine. As the two stepped back out into the main gym area, they saw a few other folk exercising; Martin waved at someone on the treadmills, pale fur poking out of their shirt as a set of six small wings fluttered experimentally, while Lurker nodded towards a regular of the gym, a tall and fat Emboar who was currently lifting weights that each were about as heavy as she was, even after her recent growth. Being a regular was leading to her getting to make friends at the gym now, and they smiled when Braixen walked in with a few spare weights to set out in the appropriate section.

"Hey Braix! How's it going?" Lurker asked, waving her over even as she rested on all fours to stretch herself out.

"Pretty good!" she replied, her shoes squeaking a little as she approached. "Between you, me, and Martin, it turns out the pool area's ahead of schedule!" she whispered excitedly, getting approving nods from the patrons. Martin smiled as he squeezed a handgrip, before setting it down.

"Excited for the chance to do some cool swimming." he said, before looking at Lurker. "Say, maybe you could invite your partner over to watch?"

They nodded, thinking about it and bringing a gray scaled claw to her beak. "It might like it, yeah!" she said, before twisting their shoulders. "And... I could use it as an excuse to get some new swimwear to show off in..." She smiled and blushed a little, before looking down at her chest, still growing breasts kept tight in their top, abs starting to grow visibly muscled under the feathers. "Um, changing my exercise regimen won't mess with these changes, will it?"

Braixen laughed a little. "Nah, at most you'll just get some different muscle growth. The cute bird look? That's all you, we didn't even pick it." she smiled, tail wagging excitedly as she turned to leave. "Oh, and if you want help finding swimsuits, you know who you can ask!"

The two gym patrons watched as she ran off, returning to some other administrative task. Martin ran a hand through his mane as he approached the weights, taking one of them in his hand and feeling it for a moment. Turning to Lurker, he asked "Think you can spot me for a change?"

"Of course! It's only fair after you've been my spotter so long." she replied, quickly helping him attach the heavy metal weights to a bar. She remembered how even just one week ago they'd be having a harder time carrying them, and wasn't confident they'd be able to lift it at all back when still just a mouse. She wiggled their tail, only barely past her hips at that point, missing the longer mouse tail, but enjoying the feathery replacement well enough. As Martin slid onto the bench, however, she shifted her focus, ready to help pull the weight away if he needed help. Martin was fine counting out his lifts himself, but she kept track too out of instinct despite this being her first time spotting for him.

--

A feathered thigh, shielded by pale padding, struck the hanging bag hard, flinging it away from the attacker. As it returned, a gray talon struck it, sending it flying forward. Before Lurker could strike it again, however, a voice called out to them, and in the moment of distraction she got hit on the rebound and fell onto the mat.

"Oh, sorry... are you alright?" Sadie asked, extending a soft pink paw towards Lurker, helping them back onto their feet. Lurker smiled and giggled, pulling it into a tight yet soft hug.

"Yeah, of course!" she replied, poking the soft padded helmet they had on. "Always wear your gear when fight training." she added, looking over Sadie's own much more simple exercise outfit, crop top showing off its large belly, shorts hugging its hips tightly. It looked around a little awkwardly; it was hardly the only one there to be noticeably fat, but being the newcomer meant it felt much like how Lurker had when she first joined up.

"Hey, thanks for being here." Lurker said, leading to Sadie blushing and smiling before kissing the now taller bird on the cheek. It giggled when Lurker literally swept it up off its feet, kissing its muzzle as best they could with a beak, only to set it back down when they heard Martin let out a small cough, the Pyroar already wearing a set of swimming trunks.

"Hey, you two ready to try out a swim?" he asked, smiling when he recognized Sadie. Lurker nodded, pulling off her helmet, hair falling loosely for a moment as Sadie stepped forward to take in Martin's own firm muscles.

"I am, yeah, I'll just need a few minutes to change. Oh, Sadie, I've told you about Martin already, he helped me get used to being here. And, ah, also helped me start to transform like this..." Lurker said, watching as Martin extended a hand and Sadie took it.

"Nice to meet you in person," he said, fangs visible in his smile. "If you ever get a full membership, I'll happily help spot you." he added, leading to Lurker sighing a little. Sadie smiled back as it let go, looking over the gym.

"Maybe," it said, before elaborating a little. "I'm still not sure I'm up for a membership, but at least I can support one of my partners." Martin nodded along, silently accepting that it probably wouldn't join anytime soon.

"Martin, I know you work here now, but you don't need to always be recruiting, you know~" Lurker teased, gently elbowing him in the ribs as she walked past. He grunted a little, only mildly annoyed by the blow; Sadie blushed at the sight, imaging itself being on the receiving end. As Lurker left to get changed, it looked to Martin, gears turning in its head.

"Say, where do you guys buy the protective gear?"

--

After getting changed, Lurker gazed out upon the pool, only sparsely populated in the moment. The building was connected to the gym, but the ownership was shared; some sections were always open to others, but this room was reserved for gym activities on certain days. Although today was one such day, no specific events were actually in session, the day simply a chance for members to guarantee a chance at a swim without needing to worry about the larger crowd in the main pool, not that the gym pool was small.

She nodded in approval, firm muscles and soft, red feathers clearly visible with the tight bikini she wore, white and gray of the sportswear contrasting highly with her exposed body. Soon after, Martin led Sadie in, and Lurker blushed when they saw its revealing black swimwear, thin straps keeping it attached.

"Alright, ready to go?" they asked, and both of their companions nodded. Smiling, Lurker rushed to the edge, taking a small dive into a deeper portion of the pool. The others soon followed her, although they simply slid slowly into the water; Martin kicked off the edge of the pool, quickly venturing further into the water, while Sadie was a bit slower, although no less steady than the others. Soon all three were happily doing a few laps, although after a minute Lurker found herself having to stop to catch her breath.

"Hey, you alright?" Martin asked, swimming closer. Sadie followed behind, gently taking the soft feathers of Lurker's arm into its broad paws.

"Please try not to overexert yourself." it said, before giving a small kiss on Lurker's beak. It tasted a little of the pool cleaner, but it didn't mind too much. Still panting, Lurker kissed it back, ruffling its head a little with one hand. Soon enough, the two were swimming around again, a few other patrons joining them before the couple started to tire.

As they returned to the edge of the pool, pulling themselves up onto the ceramic, Lurker took some more deep breaths. Martin swam over, still energetic, but leaving the pool with his friends. "So, um, what do you think?" he asked.

"I like it!" Sadie said, its legs kicking in the water. "It's nice getting the chance to swim around."

Lurker nodded, blushing a little. "Yeah, and the swimsuits are a nice plus too." they added, before stretching out a little. "I, ah, think I need to work on my stamina more though..." they said, her breathing returning to normal.

"Well, I do know a few routines to help with that..." Martin said, before thinking about how long it had been. How Lurker had gone from a small, pale mouse to a taller, stronger Blaziken, slowly changing over the weeks much like he had. "Then again, I'm not sure if a month's long enough for that..."

Lurker frowned. It was easy to forget that their membership was going to hit its limit soon, but they were enjoying her time with the gym a lot. As she stood up, she nodded, turning to dry herself off. "I'll... think about it." she said, before turning back to the others with a smile. "Now come on! Let's get ourselves dried off."

--

Sadie turned when it heard the apartment door open, the familiar sight of its tall bird spouse soon greeting it. Lurker was beaming, quickly pulling their sweater off to reveal her muscled abs and tight sports bra. In a moment, Sadie found itself pulled against them, Lurker holding it tight as she spoke.

"So... guess who just renewed her gym membership~?" she asked, before loosening her grip so Sadie could actually answer.

"You?" it asked, taking a few steps back to get a better look at her face. Lurker smirked, stepping forward again, gently but firmly holding Sadie against the apartment wall.

"That's right!" they said, leaning down to kiss Sadie's forehead. If she still had teeth, Lurker would be flashing them right then and there, but they settled for doing the best sly grin they could with their crimson beak. Sadie blushed and squirmed in place, remembering when the huge bird before it was a smaller and more masculine mouse.

After a moment, it paused, taking a deeper breath. "Say, did you, um, shower?" it asked, and Lurker just let out a small laugh.

"I did, but I figured I'd work up a bit of an extra sweat on the way back anyway." she replied, one hand gently sliding around onto Sadie's shoulder, holding it in place.

Sadie blushed even more as it realized what Lurker was planning. In an instant, their other shoulder was pressing against its muzzle, and Sadie had to close its eyes in the tight confines of Blaziken-armpit. A small, extra thick tuft of feathers cushioned it, and Lurker laughed as Sadie only grew more excited before she let it go.

Sadie took a small step back slightly dazed but extremely flustered, before it regained its senses. Lurker continued to smile, a mean glint in their eyes. "I know how much you like being bullied, my lovely little nerd~ So I hope you like me using you as a sweatrag and punching bag from now on~" she explained, watching with a smug grin as Sadie nodded, only to be met with a powerful slap on the back that knocked it forward.

Sadie was muttering again, hard to understand, but clearly excited and affectionate. Lurker blushed a little despite her own new, more self assured and dominating demeanor, giving it a firm elbow in the side calculated to hurt but not injure it, before kissing its forehead.

"Love you too, dear~ Now, if you don't mind, I need a rest after that extra workout. Think you could help massage me with those big paws of yours?"
