The sports bag landed with a heavy thud on the floor in the corridor. Richie sighed heavily as he moved into the kitchen. His girlfriend of two years, a petite, slightly plump woman named Amber noticed him entering.

"Oh, hey babe! What's wrong?" she asked, instantly noticing his frown.

"My workout instructor quit today," he answered, annoyance clear in his voice.

"What? Why?" she questioned, turning to face him and leaning against the counter.

"He's moving out to a different city, didn't elaborate why. Apologized in a hundred ways and he said it's tough having to say goodbye with so many clients he has made here," Richie explained further.

"Wow. That sucks," Amber commented empathically. "It had to be something important so, you know, you shouldn't hate him for it."

Her boyfriend laughed.

"Of course not. He's done so much for me, I can't even begin to express my gratitude," Richie continued, sitting down by the table.

"Mmm, he has indeed," Amber added sultrily, checking out her handsome, studly boyfriend. She always was attracted to him, of course, but the fruits of his physical exercise ramped that attraction to eleven.

He was tall and short haired. He used to have longer hair, but now he cut it very short for practical reasons. Together with his natural, manly features, and the slightly more chiseled look that came from regular physical exercise gave him a rugged, tough appearance.

Richie had always wanted to 'get ripped'. He finally made a decision of commitment over a year and a half ago. He found the best instructor he could, which quite luckily was one of the very best in the city.

At first it was difficult, but soon enough the working out became a habit. Under careful, proper guidance all the hard work has paid out several-fold. He wasn't nowhere near ridiculous bodybuilding levels, but it was clear that his genetics favored the building of strength and muscle.

"Still, it's annoying that I have to look for a new one, you know? Making sure it's going to be someone competent and all that."

"It can't be that hard, right? Besides, after all this time, do you even need an instructor?" Amber asked, helpfully and cheerfully.

"We're being pretty swamped at work, so I really don't have neither time nor patience for all that 'researching'. And, since I can afford it, I'd rather not get complacent and, you know, make sure I'm doing the best for myself that I can."

"Hmm," Amber hummed, making an expression of wonder as she looked up.

Richie watched her with a small, expectant smile. She was so cute when she did that. Amber wasn't the most attractive woman, certainly not in the physique department, being more on the plump and fluffy side, but he didn't care. He loved her for who she was - his beloved girlfriend of two years, always full of pep and help.

"Tell you what, how about I find someone qualified for you? This way you won't have to worry about it, I get to help out, and you get to continue getting...yeah, haha," she said as an idea struct her, ending, once again, on a sultry note. Her boyfriend was just so handsome!

"Oh! Sure, that would really help me out," he said, pleasantly surprised. "You sure about it?"

"Definitely, leave it to me," Amber added, determined to help her boyfriend find the best candidate she could.

Richie stood up and walked up to her. She watched him with anticipation and a smile.

"Thanks, baby. You're a peach," he said kissing her lovingly.

Amber melted from his kiss, warm love radiating through her like a pleasant, golden current. They broke the kiss after a long moment.

"Haha, yeah, better believe it!" she added jokingly.

He smiled. A short, peaceful moment of quiet followed.

"Alright, I better hit the shower and then organize some stuff for work. Big deal going down," he explained, turning around and heading for the bathroom.

"Oooh, sounds important. Leave you to it," she added happily, letting him go.

Next day, after Richie returned from work, tired and exhausted, thinking of nothing else but a warm meal and a relaxing shower, his girlfriend surprised him.

"Rich?" Amber called out as she heard the door being opened and closed.

"Yeah, it's me," he answered tiredly.

"I think I've found someone great for you. Come take a look," she continued, sounding excited.

It took him a while, being sleepy and all, to realize what it was about.

"Found as in...oh, you mean an instructor? Okay, hold on," he announced.

Amber waited patiently, sitting in front of her laptop. She was excited to show off her find. She spent several hours during these two days searching for the best candidate, making sure as much as she could that her boyfriend wouldn't be disappointed.

He hanged his jacket, took off his shoes, and placed down his briefcase. It thudded softly as it fell to the floor. After grabbing a refreshing drink in the kitchen, he headed towards the room Amber was in.

"Alright, let's see him," he said, stepping closer to the desk.

"Her. It's a woman instructor." Amber corrected him.

"Oh," he let out, surprised. He bent down, leaning against the wooden surface, and looked at his girlfriend with a raised eyebrow. "You, uh, sure it'd be the right-"

"Yeah, absolutely! Look, she's got great credentials," Amber's excitement was high and plain as she pointed at the screen.

He continued on looking at Amber for several more seconds. There was a bunch of reasons he was both skeptical and reluctant, one of which being doubt that a female fitness instructor would be as keen on heavyweight exercise as he was. Finally, he gave in and faced the monitor.

Shown on the screen there was, obviously, a workout instructor's offer and profile. Megan, aged twenty four. The list of credentials, references, positive reviews and such was indeed very impressive. But that wasn't the most eye catching thing there. It was the woman's photo.

First of all, it wasn't the kind of photo you might expect from a professional trainer. It was more like a photo that you might, to be honest, see on a dating website. It was clearly like a selfie, quite top down, and the woman didn't bear a friendly, welcoming smile but rather...quite a seductive one.

She was beyond good looking. Absolutely gorgeous. Symmetrical face, full lips, cute nose. She had dark red dyed hair done in a ponytail and even without make up she looked...naturally slutty.

Her outfit was certainly sportswear but the tight leggings and a sport top that looked a size too small made it seem less practical and more for showing off her body. Especially with the top-down view of the photo straight into the deep cleavage between her clearly very big, very shapely tits.

They stood in contrast with her abdomen, which was exposed right from underneath her boobs all the way to dangerously low levels. Her abdominal muscles were quite defined, putting a great contrast between her sizable rack, hips that were wide and feminine, and legs that clearly displayed firmness and tautness of supple muscle.

Thus, it went without saying that Richie couldn't help but admit to himself that this woman was pretty hot. He couldn't help but really take in the photo, his focus sliding all over the displayed curves.

There was a lull of silence. It was Amber who broke it first.

"Sooo...whaddya think?" she chirped.

"Uhh," he broke himself out of his accidentally-lustful, staring-filled reverie. "I mean, ekhem, I don't know."

"Whaaa-? What's there not to know about? She's great!" Amber protested, expecting more enthusiasm.

Richie flinched a bit, wondering how to put his concerns into words.

"She, uh, looks a bit...slutty."

Amber rolled her eyes comically, sighing.

"Oh, come on! So, just because she's pretty she's a slut? She clearly knows what she's doing fitness-wise!" his girlfriend argued, seemingly not bothered none by the woman's sex appeal.

Richie glanced at her with slight disbelief, raising his eyebrows.

"I was thinking more like...you might be jealous?"

She laughed merrily.

"Haha, why would I be jealous? I know you, I love you, and I trust you. I'm absolutely fine with her, if she helps you continue getting in shape. I mean, I've no clue how it could be even possible to get even better with you," she snuck a peek, eyeing him up and down. "But if anybody does, she's gotta be one of such people."

Richie breathed slowly, wondering. Amber watched him expectantly.

"Okay, I-"

"Yay!" she interrupted cheerfully, glad with herself.

It was his turn to roll his eyes and smile. It was clearly a high-stakes game for his girlfriend. As such, a part of him was too lazy to spend an extended amount of time looking for THE best instructor, another part of him didn't want to disappoint his girlfriend when she had clearly put in some work, proud and excited because of her find, and yet another part of him was, indeed, curious what he could learn from someone with that obviously large amount of qualifications on display.

Of course, a more literal part of him was, in fact, getting hard at the thought of meeting a woman this sexy in person, then proceeding to get sweaty together...exercising. Naturally, he'd never admit it, not even to himself.

"I will give her a try, see how it goes," he finished his sentence.

"I told ya! I told ya I would find someone fantastic."

"Yeah, yeah you did. Thanks babe," he confirmed and kissed Amber's forehead.

"No problem. I'll try to book her for...how about same times you'd have had with your regular one?"

"That'd be perfect for me, yeah. Where does she work?"

"Oh, she has her own gym."

"Really? he asked, incredulous.

"I keep telling you she's a pro," Amber answered smugly.

"Kay. You wanna arrange everything yourself then while I go grab a bite?" he asked.

"Yup, yup, yup. Leave it all to me."

He kissed her forehead again, then headed down to the kitchen. Too tired and hungry to bother thinking about the upcoming first workout, he practically forgot about it all.

Amber, meanwhile, prepared to call the listed number. Too oblivious and innocent to have any doubt in her mind about the rightness of her choice.

---

Richie's girlfriend kept true to her word and thus managed to arrange for the workouts to be in the very same periods he would have had with his previous instructors. Actually, Megan initially had those times all booked and sounded quite disinterested in changing her schedule.

Upon hearing that it was Amber's boyfriend she would be training, however, and upon inquiring that he was, as it happened, tall, very handsome and quite ripped already, her tone quickly changed into a far more agreeable one. The innocent girlfriend didn't see anything wrong with that. If anything, Amber herself would also be quite eager if she were to exercise and had the opportunity to do it with someone like her beloved man.

It was a warm, sunny afternoon. Richie pulled into the parking lot that was in the vicinity of the gym. It was in a good location, midway between his home and workplace. Already dressed in his sport outfit, which consisted of a tank top and shorts, he grabbed his bag from the backseat and headed towards the entrance.

Many other shops and various offices rented out the spaces in the building, so some traffic was present. He entered one of the main entrances to the building and looked around curiously as he went down the corridor. Modern, commonly present design, all in all nothing special. It took him a while to finally notice the gym's sign inside. He headed towards it and opened the door.

It was a sizable place, which hinted that Megan had to be quite successful in her practice to profitably afford it. There was a small area past the door, a reception of sorts, but there was no one in sight.

"Hello?" he called out.

"Coooming," a woman's voice came from deeper inside.

After hearing the answer, he proceeded to wait patiently, checking out the various decorations and a few diplomas and certificates that hung on the walls.

Megan was quite interested in meeting her new client. She had many of them, of course, being as successful and capable in her field as she was. Despite that fact, she wasn't overly ambitious and her schedule was not quite filled to the brim. Still, that was what she claimed as she rejected nearly all of the new prospects.

In spite of her fitness-freak nature, she was quite lazy. Thus, she preferred client quality over quantity, demanding hefty payments from women who desperately wanted to become as attractive as Megan, or men who even more desperately wanted to get it on with her. Not many of the latter got the chance, however, failing to meet her rather high standards.

She was, in fact, an unashamed slut when it came to sex. She loved brazenly teasing these men who had nothing but their wallets speaking for them, especially if they had wives and girlfriends that were nowhere near Megan's league.

Thus, always eager to meet a new stud, she quite happily accepted Amber's request. Not for money, but purely for a sexual prospect. Megan wasn't worried about Richie being taken. After all, she had some experience with taken men. She just hoped that he would not disappoint.

Strategically fixing her deep red dyed hair into a ponytail, she entered the reception area with her elbows raised above her shoulders.

"Oh, wow," she let out as she saw the man standing there. "Hellooo...you must be Richie, huh."

He was caught by surprise by Megan, turning to face her. His first thought was of how huge her boobs were, stuck in a tight pink sport top. Then there was her deliciously looking tummy on display and leggings, also of pink color, that just as tightly hugged her legs and hips.

"Yeah, that's me. Hi. And you're Megan, right?" Richie replied, instinctively taking a confident, charming attitude and tone, as if trying appear his best in front of the impossibly attractive female. He stepped towards her, extending his hand. "Pleasure to meet you."

"Mmm, pleasure's all mine," she purred sultrily, ostentatiously checking him out as she squeezed his hand.

He was tall, oh yes. And very handsome. Her eyes slid along his exposed skin, taking in the bulges of his muscle and feeling moist warmness start oh so slightly to pool deep inside her abdomen. It made her feel alive to be in the presence of someone she instantly knew she was attracted to.

"I've gotta say, your...aah?" she asked, still shaking his hand. A bit longer than appropriate, but...she liked his strong, firm grip.

"Girlfriend. Amber," he replied. Her skin felt silky smooth to his touch.

"Riiight, Amber...she mentioned you were quite the stud but I've had no idea you were this good of a hunk!" she complimented him brazenly and directly. She wanted to see how he'd react.

"She, uh, she did? Well, thanks," he was surprised, wondering exactly what kind of a conversation these two women had.

"So...whaddya think of me?" she said, smirking. She then posed a little bit. "You're not gonna compliment me back?"

He chuckled nervously, feeling a flash of heat on his cheeks. Reflexively, he checked her out again.

"I, uh, hah, I don't think I should answer that," he dodged the answer as he took in her immense sex appeal. She smelled so fucking sexy this close.

"Hey, don't be an asshole, now. I'm hot, right?" she asked rhetorically and slightly aggressively.

Richie was taken, once again, by surprise because of her suddenly brash tone.

"Yeah, you are, and I think you know that," he replied honestly before he could catch his tongue. He realized a bit too late. "I, uh, I mean...don't tell Amber I told you that, heh."

"Ohhh nooo, I certainly won't let your girlfriend know you find me totally hot and sexy," she purred, biting her lip. She felt irresistible in moments like this, her lust mixing with feelings of invincible confidence.

Richie felt his heart beat faster and his blood flow downwards. She stood really, really close, and her presence was making him forget all about his girlfriend.

"Aaanyway, how can I help you?"

He coughed, regaining his composure. After all, he came here to train, not flirt with a busty, scantily clad woman.

"My previous instructor left and I needed to find a new one. My girlfriend found you and, well, I want you to help me train and maximize muscle gains."

"You mean get fit and ripped?" she asked, then ever so gently places her hand palm-first on his abdomen, copping a feel. "Daaamn, I don't know if a man can get any sexier than what you're rocking right now."

Richie instinctively flexed his abs and felt his dick throb at her touch and comment. Hearing this sexy bitch say things like that was really empowering.

"Well, I think I haven't quite reached the peak I want," he replied back.

"Then in this case...we'll see if we can reach that 'peak' together," she purred, insinuation thick in her voice. She looked up into his eyes, her own twinkling naughtily. "Ready to get started?"

He breathed slowly and deeply, feeling her scent as if overpowering. Amber, and his love and loyalty to her were the furthest thoughts away from his mind right now.

"Yeah."

"Follow me then," she answered, turning around, smirking already and sticking her ass out.

Megan felt irresistible and she knew she was. This handsome stud was responding to her just as positively as she wanted. She struggled not to just let her slutty desires take control, drop to her knees and suck him off right there.

Richie's eyes fell down, glued to her ass. At the sight, he almost forgot how to walk. Those globes of hers were a perfect example of exactly how much good for mankind squats were able to accomplish. Her heavy flirting and rampant sex appeal made him struggle not to grab those pink leggings, rip them open and get to the goodness inside.

They headed forward, walking a bit too slowly. As if rather than moving from point A to point B, they unconsciously kept prolonging their foreplay. From the reception they went through a small corridor holding the bathrooms and changing rooms, where Richie stopped for a moment to leave his bag. They soon entered the main hall of the gym.

Fluorescent lighting made it nice and bright. The hall was laid out with a shock-absorbing flooring. On one end there were many additional sport mats, including a couple yoga ones rolled up in a corner. On the opposite end there was a whole bunch of various gym equipment, including a bench, barbells, dumbbells, kettlebells, a pull up bar, various balls both large and bouncy, and small and heavy. Finally, there was a small stereo set.

A quite well equipped gym. Richie looked around impressed, before returning his gaze onto something he was far more interested in at the time.

"That's my gym. You like?" Megan asked as she waved her arm around, turning to smile brilliantly at the handsome man behind her.

"Quite so, yeah. Very impressive," he said then, trying to appear unfazed.

"Thanks. Alright," she clapped her hands. "Shall we get started?"

"Yes," he said, nodding while unknowingly staring at her tits. "And like I said, I want resistance training. Muscle growth, strength and endurance."

"Gotcha, babe. I'll make it really hard...for you to last long with me," she flirted, smirking with eagerness.
