Slutty Workout Instructor

Richie smiled, raising his eyebrows at her innuendo. Admittedly, he neither should engage or enjoy it...but he was.

"We'll see about that," he replied confidently.

Megan headed towards the stereo and started up a playlist full of workout music. The kind that was just right for getting one's blood pumping.

"First, let's warm up," she said as she returned to face him. Smirking, she began with simple jumping jacks.

Richie followed her lead. He watched very intently the incredibly sexy woman in front of him bouncing up and down, her huge boobs shaking violently, barely constrained in that pink top. That sluttily-red ponytail swinging back and forth. And all the firm muscle contracting visibly.

Their pace increased, their breathing sped up, and their focus heightened. Megan began introducing various other warm-up exercises, such as side shuffles, squats, a couple of light push-ups and so forth.

Megan knew she was being ogled during it with all intent. And she wasn't the only one doing the ogling, as watching that hunk of a man's muscles soon start glistening with sweat made her almost pause and forget she was supposed to be leading the exercise. In response to that she quickly returned to jumping jacks again, this time with her ass stuck out to him so Richie could really watch Megan's mouth-watering butt moving up and down. It continued like that, raising the bodily temperature of both of them.

After an intense ten or so minutes, she called it to stop.

"Alriiight, hooh," she breathed fast, catching her breath and calming her mind. She was getting a bit too horny and, at least for now, she needed to keep up appearances. "That's enough."

Richie also breathed hard, nodding as he finished up warming up his arms, elbows and wrists. He tried not to think about the semi-hard bulge tenting out his shorts, instead focusing on the workout he came here to do proper.

She slowed it down with stretching, motioning for Richie to follow. As he did, she began explaining.

"So, I guess you know the basics and whatnots of the exercise, you certainly show these results..." she talked in-between gasps for air as she stretched out her legs with lunges. She made sure to push out her chest, of course. "And I'd like to introduce a concept that not many trainers and instructors recognize, and that's the impact of testosterone during exercise."

"First time hearing it," he commented. As he stretched he could feel his dick slightly struggling against his clothes.

"Right, so, since you're a man, you should maximize the effect of that hormone. All that comes with it," she continued, standing wide and undulating her hips in a circle sexily. "One part is, you know, struggling against something. Fighting. That stimulates the hormone production."

"Oh...right. Interesting. Yeah, that makes sense," he nodded, for the first time since he came to Megan's gym thinking about proper exercise technique rather than...something else.

It made sense to him. After all testosterone was an important hormone that very clearly influenced the muscular growth in men. Often times as he struggled with a heavy weight, or fought not to collapse under his own during pull-ups or push-ups, he felt the exercise affect him the most.

"Fantastic, so you agree," Megan let out, talking with a breathy, gasping voice. She wasn't that out of breath...she just wanted him to hear that sensual sound. "Another part is sexuality. Getting horny and stuff."

"Right," he confirmed readily, without thinking. "Wait, what? What did you say?"

"Getting horny," she repeated casually. It was slightly muffled, as she was now bent over in front of him, her ass sticking right towards him and her palms flat on the floor.

Richie's eyes were glued to the sight again. Images of just shoving his dick into that impossibly sexy rear came unbidden.

"I don't get...how's that going to help out with a workout?" he asked, ignoring the sheer fact that this line of 'reasoning' was, at the very least, inappropriate.

"I told you, it stimulates your testosterone," she replied matter-of-factly, pushing her ass out to him and swaying it invitingly.

Megan was amazed with how casual and professional she sounded as she explained some made-up idea she came up with. Imagining her own explanations, what they entailed, they made her pussy moisten. Especially with those few sneak peeks she sent Richie, noticing the bulge in his shorts. After all, whatever she was explaining was far less for the benefit of muscle growth and far more of her own benefit of getting laid with some other for-sure inferior woman's hunky boyfriend.

"Uhh..." Richie was at a loss for words. He didn't know what to reply. Also, that delicious, mouth-watering ass in front of him was taking up too much of his brainpower.

"Like, to sum it up, I know you're attracted to me, I can see you getting hard in your shorts," she pointed it out loud, trying very hard not to sound thirsty but instead purely professional.

"Hey, hold on!" he straightened up, willing his half-erection to go down. This was going too far.

"No, no, it's okay. That's the point," she straightened up and faced him, the skin of her deep cleavage and gorgeous face glistening with sweat. "I'm super hot, you're attracted, and it's just perfect. This stimulates you, pushing your testosterone into overdrive and, thus, your muscle gains!"

Megan felt like giving herself an acting award inside. She sounded so believable, so convinced! And, unbeknownst to him, all the while she kept thinking about bouncing her tight, wet pussy up and down that stud's dick!

Richie stared at her with his mouth open, shocked into silence. She looked so fuckable, warmed up and hot like that. He almost didn't remember why was he protesting, all she did was give him permission to get as hard as he could for her.

"I mean, look, I told you that, in my opinion, you're hot as FUCK as well," she commented seriously and honestly. "Seriously, if you didn't, like, have a girlfriend? I would fucking ride your dick till I passed out! I would fucking bounce on that fucking hard pole you've got for me till you screamed you loved me!"

The handsome boyfriend's eyes almost fell out of his sockets. He felt his dick throb and become twice as hard as before, increasing vastly the pressure he felt in his shorts. He had little doubt this impossibly sexy vixen was horny for him before, and he certainly didn't have any doubt now. He knew, deep inside, he was just as seriously into the idea of having sex as she was.

But he was just her client, and she was just his workout instructor. They barely met like a half an hour ago, and, most importantly, he was taken. In a relationship. With a girlfriend of two years, Amber, who was nowhere near Megan's sex appeal, but that last fact didn't matter. At all.

Megan coughed, noticing she was being a bit too honest, making her play a bit less convincing.

"The point is - so what? We're just exercising together, and you said yourself you wanted to maximize muscle gains. And that's how I know to do it. Let's be professional here, alright?" she continued, calmly and matter-of-factly. She then turned and headed towards the gym equipment.

Richie watched her incredible, swaying ass intently, before coming to a decision.

"Ekhem, yeah. Yeah, absolutely. Right. I should just...give your method a try, see how it goes," he answered, pretending not to just disregard his concerns so he could continue ramping the flirtation further. Pretending to ignore the almost painful, lustful sensations inside his member, pulsating in the rhythm of his rapid heartbeat.

"Exactly! It's not like we're just..." she took a breath, feeling dizzy from the horniness that felt like a glowing star inside her. "Going to start fucking right here and now...right?"

"Right, obviously. So, uhh...what's next?" his was voice throaty and shaky.

"MMmh, how about we get to pumping some iron? Whaddya think...stud?"

"Yeah, uh, that sounds good."

She turned around suddenly, almost causing him to walk straight into her. Then there would've been nothing stopping them from getting well-acquainted with each other's bodies.

"Come on, you need to engage. Maximize that testosterone," she said with a challenging tone, brazenly shaking her tits at him, trying to seem like she didn't desperately want him to check her out, then grab her and fuck her brains out. "Get those lustful juices going."

Megan was so horny for him. Couldn't he fucking see that? He should just fuck her, relieve her tension!

"Oh, fuck," he gasped, as he stopped in his tracks. He checked her out thoroughly, over and over, drinking in her irresistible appearance, breathing in the intoxicating, feminine scent. "I, uh..."

He swallowed his saliva to calm himself. He was just trying a new method of improving his workout routine. That was it. He wasn't serious. At all.

"I want to show off my bench presses to you," he said, staring at her tits boldly. He then looked deep into her twinkling eyes. "You sexy bitch."

Megan felt her heart skipped a beat, and the lustful star inside her explode. She almost fell towards him, intent to mash her lips against his till they breathed each other's taste.

"Oh, God...that's the spirit. I want to see it so bad," she whispered, biting her lip, watching him intently.

Richie moved forward and past Megan. She glanced down, noticing a huge tent in his shorts.

"Wait, hold on, let's make sure your core is nice and warmed up first," she said, coming up with a quick idea.

He paused and looked at her for silent few moments.

"What for?" he asked, curiously.

"Just trust me. Lie down and do a couple leg raises."

Richie shrugged and got down to lie on his back. Before he could do anything, however, Megan moved so that she ended up with his head between her feet.

"Fuck," he commented at the sight straight upwards into Megan's leggings-clad pussy. The most attention-grabbing detail was that the material as ever so slightly wet there. "What are you..."

Megan silenced him by dropping down to her knees and positioning herself so that her delicious, addictively-smelling, barely-clad pussy hovered right above his face. She could feel her lust liquefying and pulling, and she could feel Richie's stare burning into her.

She wanted to choke him with her nether lips really, really bad.

"Go ahead. And focus on the pushing that testosterone. Just stare up and visualise...mhh, eating me out for example...and, yeah, do the leg raises," she commented, trying not to let her voice shake too hard.

Lust was thick in the air around them. Richie, hazy and rationalizing his urge as 'testosterone aid', surprised her by bringing his hand up and spanking her fantastic rear. His hand tingled from the firmness of her sexy glutes, and the crisp sound of the spank reverberated inside his skull.

"Fuck!" she gasped in surprise.

It was increasingly difficult for her to restrain herself. She instantly placed her hands on his abdomen, groping greedily. He then, finally, raised his legs.

"God damn, it's like a steel grate," she whispered, squeezing around. "I wanna grind my pussy against it."

"Oh fuck," he groaned. He really, really wanted her to do that. Just rub against him till she squirted. His member throbber painfully, constained in the damned clothes. Still, all he could do was continue to lift his legs.

"I just want to sit on your fucking face. Make you drown from how wet you've made me!" Megan exclaimed truthfully, her fingers sinking as much they could into his hard muscle. It felt like touching an electric fence, the lust tingling her fingers and setting her insides on fire.

He groaned loader, contracting his abdomen hard and raising his legs up, then lowering them down. Staring upwards into clearly wettening material of the leggings. All the while the strongest contraction was of his pelvis muscles, as if trying to rip through the clothing so that Megan could just fall forward and choke her beautiful mouth with his dick.

"Damn, baby, I can see your shorts on the verge of tearing. You've gotta be sooo uncomfortable," she cooed sexily, grabbing his dick through his shorts. "How about you take them off for me? Let it breathe?"

Her touch felt so good he just dropped the legs down and pushed upwards to meet her hand.

"I don't...think it's a good idea," he answered, hoping she would grab his dick harder.

"Oh, come on, I did so much for you. Let me see what you've been teasing me with all this time," she pouted like a schoolgirl.

"Fuck, fuck, fuck...okay, fuck, okay. Take them off," he agreed, lifting his hips up and moving his hands down to help.

They struggled impatiently, uncaring whether it was appropriate or not. All Megan wanted in that very moment was to see that dick that was so hard for her, that aroused state she worked so diligently for.

Finally, it came into sight. Richie breathed with relief, as the material of his shorts and underwear was making it really uncomfortable. Megan, on the other hand, gasped with wonder.

"Fuck, that's such a nice dick," she whispered, lowering herself.

Richie froze as he felt Megan's silky hand wrap around his throbbing, rock hard dick, and then sensed her hot breath against the sensitive tip. His mind was flooded with images of those plump, pouty lips of hers wrapping lovingly around his cock and sucking till he dumped the entire contents of his balls down her slutty throat.

It never came to pass. After many long, so very long, torturous moments...

"Okay, uhhmmmm," Megan half-whispered, half-moaned with great regret. She moved off him slowly. "How about those bench presses? Just put on whatever weight is enough to challenge you."

Richie stood up, clearly on shaky legs. He reminded himself that all his lust he was feeling was just a tool. To push his testosterone into overdrive, and to let his workout reach new heights. He shifted his focus into beating a heavy weight with his strength.

She watched him with fascination as he put on weight after weight, clearly wanting to show off for the sexy female. It made her gush with appreciation and interest, she just loved it, feeling like a queen. Like she certainly was far, far more important than Richie's what's-her-name girlfriend.

"Holy crap, you can lift all that?" she commented when he finally finished and moved to lie down on the bench. "God damn...I want to feel you fuck me in a stand and carry!"

He was thankful he had his shorts off, because hearing that would've surely made his dick rip through them. His legs almost gave out and he almost turned around, this close to pushing Megan down on the floor and pounding her naughty pussy till neither of them had any energy left for an actual workout.

Megan walked closer, biting her lips constantly. She was horny, her lust feeling like red plasma coursing through her body. Her pussy was throbbing with heat and need. She was determined to drop the pretense at the first opportunity.

Richie sat down and fell back onto the bench. His erect dick stood proudly at the sight of hot-as-hell hottie that clearly was just as turned on as he was. Trying not to let distractions get in the way, he forcibly shifted his focus on the impressive weight he set out to train with.

Noticing he no longer could see her, focused solely on the barbell, Megan sensed her window of opportunity. She silently and gracefully slid her tight, pink leggings off her. Her panties were completely soaked through, her pussy steaming hot.

It's been a while since the last time she was this turned on. Megan felt a bit giddy with excitement, swallowing her saliva and trying to calm down a bit. This could end up very badly for her.

Richie wrapped his strong hands around the barbell, and with a mighty heave and grunt lifted the heavy weight. It wasn't close to his record, but it was definitely far above what he would begin with.

He thought to himself how Megan was right. Whether due to the fact she stood there observing and, thus, increasing his need to show off, or her whole 'testosterone workout' theory, he felt strong and reinvigorated. The difficult part was, of course, that he could barely focus on working out while all the thoughts were of fucking his female workout instructor silly.

The barbell lowered in a slow and controlled fashion. Richie breathed in deeply as it reached his chest. He then pushed upwards, flexing his muscles strongly. As the weight he fought with demanded his attention, he didn't notice Megan approaching.

He lowered the barbell again and, suddenly, as it reached his ches, he felt hot, naked skin against his own. Then he saw something pink being thrown and landing right on top of the barbell. He glanced down, his vision slightly obscured by the sexy-smelling leggings that were now hanging above him, and saw just what he needed.

Megan was naked from waist down. She moved her other toned leg around, and thus now stood with her legs around his hips. Her gorgeous, mouth-watering, shaved pussy was glistening on display, hovered and dripping wet right above his dick, which throbbed with renewed arousal. Meanwhile, his arms protested against the weight that, technically, was enough to crush him if he let go.

"Fuck! What are you, rghhhh, doing?!" he grunted, struggling, more worried than angry.

"I'm too fucking horny to wait anymore. Just keep pumping that iron, baby, while I'll go pump something else..." she purred sultrily, bending over and leaning against his abs.

"Shit, are you crazy?! Hold on, crap, wait," he panicked, holding the barbell still in place, moving his legs around without thinking, trying to escape from what was coming.

Megan ignored him, transfixed on her prize. She didn't let his futile movements distract her, and with a graceful bounce jumped right onto his lap.

"Fuuuck," Richie moaned against himself, feeling the hot, silky smooth skin press against his, nestling his throbbing cock against her intoxicating cunt.

She slid and grinded around, making her position secure. Then she lifted her sexy ass slightly upwards and, finally, grabbed his cock. Richie's heart skipped a beat, his desires torn between throwing the sexy slut off him and letting her ride him all day. At the very moment, of course, he was more worried about the weight of the barbell threatening to crush him than the fact he was about to have illicit, cheating sex with an impossibly sexy woman he just met.

"No, no, no, fuck, stop, stop," he complained half-heartedly.

"Shh, baby, just let me..." she whispered gently before slapping the throbbing, hard dick against her nether lips. "Oohh..."

Megan gasped at the exquisite sensation, and followed with several more hard slaps, which jolted her with electricity-like shocks of pleasure. Then, she positioned the tip against her entrance and sat down on the cock that's been teasing her all day. Copious pussy juice reduced friction to minimum, and with a long, relieving moan she finally, FINALLY had the handsome stud's dick balls-deep inside her.

"MMmmmmhhhh," they moaned in unison.

The gorgeous, sexy slut on top of him wasted no time doing just what she wanted - grinding hard and fast with that fantastic, unprotected dick deep inside her. She quickly worked up a pace, sliding back and forth. Their wet skin smacked loudly as she rode him.

Richie's brain was flooded with feelings of ecstasy. Amber was nowhere near this attractive, thus he was never as horny as he was right now. His girlfriend's pussy didn't feel so deliciously tight and flexible, with hot wetness and silky smooth texture wrapping his hard, throbbing cock in pure, addicting sexual pleasure.

"Oh God, now that's a fucking dick!" Megan cursed, increasing the pace even further. "Fuck, it's so good!"

"Fuck, God damn it, you...you slut!" he cursed, finally giving into his true desires in the tense situation which distracted him on every front. "Fuck, ride me, ride me just like that!"
