Boo & Kieran are (C) Boo3

* * *

Kieran tugged his laces tight, stood up, and grabbed his towel off the bench. The lean, attractive wolf wore a pair of black mesh gym shorts and a plain blue t-shirt. Thick brown fur coated his entire lean frame. He was tall, almost six feet, plus a few inches for his ears. Though he was attractive, he wanted to bulk up a little, hence the gym membership he'd signed up for online. Memberships came free with several one-on-one training sessions with a personal trainer, in the hopes the client would hire them for more training later down the road.

The wolf was in school, but felt constantly stress. A few friends recommended he work out to help and, since today was a holiday and classes were cancelled, he decided it was time to get started. The questionnaire he'd filled out along with his membership application had been forwarded to one of the trainers, he'd been told, and the appointment email came through slightly later on. The email promised his workouts would be "tailored to test him as best as possible" and "provide the optimal amount of fitness training". Kieran didn't know much about working out. He'd done some running back in high school and ate decently, but was an otherwise average specimen. Still, he was glad the gym was being aggressive in its marketing, at least. Hopefully they could deliver on their promises.

The main floor of the gym included lots and lots of equipment. Most of it was of the treadmill and bicycle variety, including long rows positioned in front of glass windows so passers-by could see the clean, well-lit interior. The free weights and other such training equipment was mostly in the back, where the people exercising could grunt and shout all they wanted without disturbing the rest of the patrons. The gym, "Prime Cuts," was fairly new, but had a decent reputation. The upstairs included additional equipment, massage rooms, and a couple saunas and hot tubs.

Kieran had checked in at the front desk when he first entered the gym, so when a trainer approached him upon leaving the locker room, he wasn't surprised. He was surprised, however, at the size of hir.

The rabbit was huge. Probably eight feet tall, counting the ears, and built like a steamroller. Shi wore a tight-fitting sports bra around hir chest with the gym's name and logo - a picture of a generic outlined body with dotted lines marking out major muscle groups. It hugged hir massive chest, lifting and supporting what were easily one of the largest pairs of breasts Kieran had ever seen. Shi smiled at him as shi strode over and he couldn't help but stare at the generous bulge in hir hip-hugging nylon shorts. The fabric clearly outlined the male bulge. Modesty, it seemed, was not a prerequisite to employment.

"Hi! You must be Kieran. I'm Boo. Pleasure to meet you," the lapine said, extending a hand.

Kieran felt his paw squeezed by a massive set of fingers. A little more power behind the handshake and he was convinced shi could have broken his hand right off of his arm. His tail wagged behind him nonetheless, because trainers as built as this one could no doubt get results.

"Nice to meet you," Kieran said at last, already nearly winded just from being near the generously-endowed rabbit.

"Well, from your questionnaire, it seems like you're really interested in bulking up, huh?" shi said, turning to walk towards the free weight section in the back. "Follow me and we'll get started!"

Kieran gulped as his eyes locked onto hir rump. Oh, he'd follow hir all right. Hir ass, hugged tight by the nylon shorts, shifted up and down, powerful glutes performing a mesmerizing dance under a wispy, fluffy tail. The wolf looked down, worried he'd sprung a boner, but so far, it wasn't too noticeable. He casually adjusted himself, trying to be inconspicuous, as he followed along behind the huge herm.

Shi stopped in front of a set of one-handed weights.

"Let's start slow to see where you're at," shi said, reaching down to pick up a 15-pound bar. "We'll just do some basics so I can see your form for now. Go on and have a seat. We'll start with curls."

Kieran nodded. He was intimidated, but it was clear shi was friendly and willing to help even a newbie like him. He took a seat on the bench and reached out for the bar, which shi handed to him. He felt self-conscious, but started doing his reps, trying to remember everything he could about weight lifting so that he wouldn't come off as a complete idiot.

"Oh, that's good," shi said, leaning over. "You're doing fine. Here... put your elbow closer to your knee, like this..."

The rabbit's huge paws reached out, grasping his thighs and spreading them apart. His eyes went wide as he realized that by looking straight ahead he could see straight down her chest. He gulped as her paws maneuvered his elbow, and when shi finally straightened up, he nearly forgot to start again.

"That will make sure you're working as hard as you can. Puts the center of balance farther out," Boo said, smiling. "Feel the difference?"

Kieran gulped again and nodded. His mouth felt hot and dry and he licked his lips as he looked down, hoping he hadn't been staring. It was more difficult now and, after Boo instructed him to switch arms, he did so. A few more reps and shi stood him up to run him through more arm exercises.

"Very good!" shi said, nodding. "You've got a good body for this. I'll be able to bulk you up in no time."

Kieran grinned as shi had him hold the weights above his head with both hands and lower them down back between his shoulder blades. Shi stood in front of him, breasts against his face, as shi reached back, helping him lift so shi could show him how to lift straight up and down. He could feel hir package sticking into his gut and shuddered involuntarily.

"All right... let's move on," shi said. "I think your arms are in pretty good shape, but we're gonna have to hammer those biceps into shape, huh?"

The legs were next. Kieran quickly discovered he had a love of squats. Every time he dropped down to his haunches, he came face to face with the rabbit's very stuffed shorts. Hir musky scent flooded his nostrils as he lifted himself back up, only to come face-to-face with hir chest once more. Shi kept encouraging him as shi ran him through a few more exercises, before ending with plain old sit-ups and push-ups.

"All right... that was really good, Kieran. Let's take a break, and then we'll go back through so you can practice a little more," Boo said. Shi took a seat on a bench across from him and reached into a duffel bag, pulling out a towel. Shi wiped off hir face and smiled at him before reaching back in and pulling out two plastic water bottles. Instead of water, however, Kieran could see the clear plastic bottles were full of creamy white liquid, probably some kind of protein shake.

Boo handed him one and opened the other, taking swig. Kieran followed suit. The liquid was surprisingly thick and salty and he coughed as the smell hit him.

"Yeah, this stuff stinks, but it's really good for you," the rabbit said, finishing hirs off in a few more gulps.

Kieran nodded and raised the bottle to his lips again. As the musky fluid poured down his throat, he shivered. The taste wasn't bad, just... unusual. Boo smiled at him as he finished and handed her the bottle. Surprisingly, he felt better. The oncoming soreness in his body diminished in a few minutes as he chatted with the rabbit. Shi outlined a progression for him, working him up through the free weights, which he'd two three times a week, plus cardio for two days, and two rest days. The schedule she proposed worked well with his school hours and, considering how close the gym was to campus, he realized it was going to be easy and incredibly fun getting into shape. Plus, Boo had already provided enough material to fill his spank bank several times over.

The rabbit stood, stretched hir arms over hir head, and flexed hir entire body, limbering hirself up. Kieran's jaw nearly dropped as his eyes roamed from hir powerful shoulders, across the rabbit's taut chest, down hir perfectly formed six pack, over the bulging maleness trapped in hir small, tight shorts, and finally down hir meaty legs, each thick thigh trembling with power.

The wolf was definitely erect now. As he stood, he turned to the side and tried to adjust himself so it wouldn't show as much. Boo didn't appear to notice.

"Okay! You ready to do this? Your first real training session," Boo said. "Don't worry, I'll go easy on you."

Kieran nodded as he laid himself back on the bench press and reached up to grasp the bars. They hadn't done this one before and his eyes widened as he looked up to see Boo towering above his head. He could barely see hir face past the swell of first, hir thick package which hung over his forehead, and second, hir breasts, which viewed from underneath were even more impressive. One of hir ears tipped over as shi leaned down to grab the bar next to his paws.

"Okay, I've got this setup with sixty pounds. If you can do more, I'll add it on after a few reps, okay?"

Kieran nodded, focused on the bar - instead of hir body - and pushed upwards. It was easy - surprisingly so. The wolf grinned as he pumped the iron rapidly up and down for ten quick reps.

"Okay, rack it up, powerlifter," the rabbit said, laughing. "I'll add some more on."

Boo smiled as she lifted two of the sixty-pound circular weights and slid them onto the bar. Sixty pounds may as well have been six to the big lapine.

Readying himself again, Kieran grasped the bar and pushed. Every time he sucked down air, it came perfumed with Boo's thick, musky scent. His erection throbbed in his shorts, clearly tenting them, but there was nothing he could do about it now. 'Sides, Boo had probably seen it all before.

Twice as much weight was more difficult, but doable. Kieran was surprised - he hadn't thought he'd be able to lift so much, being that he'd never exercised properly before. He felt amazing, though. Full of energy. Whatever was in that drink was really working.

Boo grinned down at the wolf on the bench, watching as his arms lifted the solid weight easily. He didn't know it, but the drink was spiked with a little something extra. The rabbit didn't think he'd mind once he saw the results... and shi certainly didn't mind watching the attractive wolf's body begin to grow. Not to mention that tasty erection stuck in his shorts. The wolf wasn't a shrimp to begin with, so the results were bound to be spectacular for a first session.

"Good job, Kieran. Let's try those squats again."

Kieran racked the bar and jumped off the bench. He felt even better and shook his arms, working out the tightness that came from the heavy lifting. He curled an arm and grinned. Was it just him, or was his bicep already showing signs of development? Nah, just his imagination... or was it?

He moved to the squat bar and bent underneath it, positioning it across his shoulders with Boo's help. Straightening up, he glanced to the side.

"Uh... how much weight is on here?" he asked. Earlier, he'd only done sixty.

Boo glanced at the bar from where shi stood behind the wolf. "Uh... let's see... two hundred. Yup."

The wolf almost fell over, but stomped down on the floor to stop himself. "That's too much!" he said, but even as he said it, he realized it wasn't. He was standing with the bar on his shoulders, easily handling the extra weight.

"Doesn't seem like too much from where I'm standing," the rabbit said. "C'mon, let's see that squat!"

Kieran nodded, took a breath, and lowered his body. He grunted on the way back up, surprised at the ease with which he pushed the bar back up. His fingers curled around the metal bar as he went back down, grinning happily as endorphins flooded his brain with positive energy. This was easy!

"Good, Kieran, good! And another... excellent..."

Kieran panted as he ran through several more. His thighs burned as he stood and finally racked the bar. He glanced down and quickly readjusted his erection - it was sticking nearly straight out and looked, if anything, bigger and harder than before. He was gonna have to spank it more than once, he thought to himself, if it was ever going to go down again.

With Boo's musk still staining his nostrils, the wolf moved on to another set of exercises. The rabbit pushed him, urging him on, until his brain went into autopilot. He followed hir instructions, lifting, pushing, pulling, hauling, carrying everything shi threw at him. He didn't notice that, during it all, his body grew... and grew... and grew...

He didn't realize how tight his shirt was, or how his shorts, formerly baggy, were now squeezing his cock against his lower belly tightly and outlining every inch of his rod. The shorts clung to his ass, now thicker and rounder, as well as his thighs.

He exhaled loudly as he got into the zone, performing arm curls with ease, demolishing the leg press on max weight, and rapidly running through a hundred sit-ups without even breaking a sweat. Every time he lifted his chest up, though, he found he couldn't get as far as he could the time before. Soon, he realized why.

A pair of round, heavy breasts flattened against his knees every time he leaned forward. His nipples had grown and were now thick and sensitive nubs that stretched out the cotton. Boo grinned at him hugely as he stopped and stared down at himself, arms still behind his head.

"Whu... how..."

"Just getting you in shape, is all," Boo said, a devilish smile on hir lips. "And I figured this was a shape you may prefer..."

Kieran gasped as his nipples throbbed. His tits were huge! Not as big as Boo's, but still...

That's when the wolf realized breasts weren't the only thing that had changed. A tingling ran up his spin as he realized he was now a shi. Kieran gasped when shi felt a warm, strange new tingling sensation between hir legs, under hir heavy nuts. It could only be one thing. Combined with the lingering pleasure in hir erection, shi couldn't stop the low moan that escaped hir lips.

"Nice, huh? Now c'mon, Kieran. We aren't done yet! Gonna work those muscles 'til you can't hardly stand!"

Boo's exhortations took Kieran's mind off hir new body somewhat, but the pleasure running across hir breasts and new feminine sex were trying very hard to distract hir as shi returned to the bench press, did more arm curls, and especially when Boo ran hir through some lunges.

The wolf panted heavily, sweating profusely, as shi finally stood up and wiped hir towel across hir face during a break. Shi realized, to hir surprise, that shi no longer had to tilt hir head back to look Boo in the eyes. Shi was nearly as tall as the rabbit now. Kieran growled happily and flexed hir arms, curling hir biceps up, watching as newly grown balls of muscle formed under hir thick pelt. Hir belly was hard, flat like a washboard, with the hints of a six-pack. A little more work and shi'd get one. Hir thighs flexed, hamstrings popping out against hir fur. Hir tail wagged furiously above hir round, thick rump, as Boo grinned back at hir.

"Let's call it a day... I think I put you through the ringer pretty well," the rabbit said. Shi reached out and pressed hir paw against Kieran's newly enlarged shoulder, squeezing it.

Kieran nodded and took a deep breath, a blissful smile on hir face. Unfortunately, the expansion of hir chest proved too much for hir blue shirt. Two large breasts tore it to shreds, leaving tatters of cotton hanging around hir shoulders and hips.

"Oh! Woops!" shi said, lifting an arm to cover what shi could of hir double-D-cup breasts. Hir nipples tingled as hir arm fur brushed against them.

Boo laughed. "Don't worry. I'll hook you up with one of these on the house," shi said, giving hir sports bra a little tug. "They're reinforced for us big gals."

Kieran nodded, but hir expression turned to one of further embarrassment when, a moment later, hir shorts gave out as well. A massive red wolf cock jutted up between hir and Boo, reaching up nearly to the bottom of the swells of the rabbit's breasts.

"And I have something you can wear over that, as well," Boo said. "Well... maybe not right away..."

The rabbit's mischievous smile returned. "You know what I like after a good workout?" shi asked. "A nice soak in the hot tubs upstairs. Want to join me?"

Kieran's eyes flicked down to the rabbit's tight shorts, where a supremely thick, powerful length pushed around the lapine's thigh before curling down and following the leg. The tip of a meaty pink erection throbbed in plain view past the hem of the short's leg, dribbling some clear pre-cum into Boo's fur.

"That... sounds amazing." Kieran grinned as Boo turned and led hir towards the stairs, hips swaying rhythmically, more than before. The wolf watched hir climb the stairs and shuddered as hir thick wolf cock throbbed, before padding after hir a moment later.

"By the way," Boo called back to hir, "if you think today was rough, just wait until tomorrow!"

The end.
