Steamy Gym Sauna Session

Matt took a long swig from his water bottle as he entered the gym, ready for a solid upper body workout. He nodded at the receptionist and made his way towards the free weights area.

It was a quiet Thursday evening and the gym was sparsely populated. As Matt began loading plates onto a barbell for chest presses, his gaze wandered over to the squat rack across the room. That’s when he spotted a familiar figure - his ex-girlfriend Nora.

Matt did a double take. Nora was dressed in tight pink gym shorts and matching top, her slender but toned body on display. She was laughing with another girl as they set up for squats. Matt recognized her as Nora’s older sister Ariana.

Ariana had developed more feminine curves than her younger sister Nora. She had wider hips and larger breasts that filled out her top.

Matt remembered Ariana from high school. She was always the more extroverted and adventurous one. While Nora was rather shy, Ariana loved being the center of attention.

In those days, Ariana was a bit rebellious and enjoyed pushing boundaries. She would sometimes sneak out at night to attend parties or hang out with older kids. But she seemed to have focused her energy now on health and fitness.

Matt hesitated, unsure whether to approach them. Curiosity got the better of him and he decided to at least say a quick hello. After all, he and Nora had parted on decent terms.

Grabbing his water bottle, Matt headed over to the squat rack where the two girls were focused on their sets. Nora had her back to him and didn’t notice his approach.

“Fancy seeing you two here,” Matt said breezily, as Nora turned to face him in surprise...

Nora turned around, surprised. “Oh, hi Matt! Yeah, we decided to start coming to this gym since it’s so close to our place.”

“Cool, cool,” Matt nodded. “How’s the workout going?”

“It’s going good!” Ariana replied. “We’re just about finished up here actually. I’m totally beat.”

Ariana chimed in, “We’ve been following this new program that incorporates a lot more lower body work. I’m so sore but it will be worth it!”

“Anyway, we’re just about finished up here. What are you working on today?”

“Mostly upper body for me today - chest, back and arms,” Matt responded.

“Nice! You’re looking pretty jacked yourself,” Ariana said with a friendly smile.

Matt laughed. “Thanks! I’ve been trying to bulk up over the past few months.”

“Well, it does seem to be working!” Nora said, glancing at Matt’s muscular frame.

“Hey Matt, since you’re here, would you mind spotting us on a couple more sets of squats?” Ariana asked. “I want to go a little heavier but I’m too scared to do it without a spotter.”

“Yeah of course, I’d be happy to spot you both,” Matt said eagerly.

Nora bent over and gripped the barbell, getting into position for her squat set. Matt stepped up behind her to spot her, his hands hovering just above her hips.

As Nora started squatting, Matt’s hands made contact with her body. He could feel the firmness of her hips and ass through the thin fabric of her gym shorts.

Memories of sleepy weekends spent lounging in bed with Nora came rushing back. How she would wiggle her perfect butt against Matt’s crotch, grinding against his morning wood. The way she would glance back with a naughty smile, encouraging him to take things further.

Matt’s mind flashed with vivid images of Nora on all fours, ass upturned, begging him to fuck her from behind. Her melodic moans and pleasured whimpers as he gripped her hips and drove deep into her tight pussy.

Matt was jolted back to the present moment as Nora finished her set and re-racked the barbell. She turned and gave him a knowing smile, her cheeks slightly flushed. Matt released his hands from her hips, the vivid memories still swirling in his mind.

“Woo! Nice job!” Matt said, helping guide the bar back onto the rack.

“Phew thanks, that was tough!” Nora said, breathing heavily.

“No problem, looking good!” Matt said. Nora smiled shyly.

Next up was Ariana. As she stepped under the loaded bar, Matt got into position behind her, his gaze drawn to her thick, juicy ass in her skintight leggings. He placed his hands on her love handle area and felt her hips swaying as she started her set. Her big butt cheeks jiggled enticingly with each squat.

After Ariana finished her set, the three of them were startled by a man’s voice behind them. “Hey there! I don’t think we’ve met, I’m Mike, one of the new managers here at the gym.”

They turned to see an athletic looking guy with short blond hair smiling at them.

“Oh hi Mike, nice to meet you!” Ariana said.

“Likewise!” Mike replied. “I wanted to come over and introduce myself, and also let you folks try our new pre-workout supplement we just got in. It’s really fantastic, gives you amazing energy and focus.”

He held out 3 sample packets of powder. “Just mix it into your water bottle and drink it before or during your workout. The effects kick in pretty quickly, it’s some really powerful stuff!”

“Wow awesome, thanks!” Matt said, taking one of the packets. Nora and Ariana took one each as well.

Mike laughed. “Let me know what you think. Enjoy your workout!”

With that, he walked away towards another area of the gym.

“Nice! Free pre-workout!” Ariana said excitedly, tearing open her packet and pouring it into her water.

“I wonder what’s in this stuff, how good can it be if he’s giving out samples,” Matt mused, mixing up his drink.

The three of them quickly gulped down the mystery supplement. Almost immediately, Matt started feeling tingly all over, his heart rate increasing.

Nora, Ariana and Matt looked at each other with slight confusion as they waited for the pre-workout to kick in.

“Do you guys feel kind of ... tingly?” Nora asked hesitantly. The other two nodded.

“Yeah, I feel really warm ... it’s weird,” Ariana added.

They continued chatting and stretching, waiting for the energy burst Mike had promised. But after 10 minutes, the only thing they felt was an intensifying tingling sensation all over their bodies.

Nora shifted her legs uncomfortably as she started to feel a warmth growing between her thighs. Glancing down, she noticed her nipples were hard and visible through her thin tank top. She crossed her arms over her chest self-consciously.

Meanwhile, Ariana was also feeling flushed. She kept squeezing her legs together, trying to relieve the building ache in her pussy. Her breasts swelled against the fabric of her top, nipples stiff.

Matt shook his head, trying to clear the haze of arousal fogging his brain. He stared hungrily at the girls’ fit bodies, his cock slowly stiffening in his shorts.

“Okay, something is definitely up with this stuff,” Ariana said breathily. “I feel so hot and tingly all over...”

“Me too,” Nora whispered, face red.

Nora shifted her legs slightly as she felt a tingling warmth growing between her thighs.

Ariana tugged at her top, glancing away from Matt.

The three of them chatted casually, trying to ignore the flush spreading across their skin and the quickening of their pulses as the supplement took effect.

Matt realized the supplement must have been spiked with something that acted as an aphrodisiac.

Matt tried to shake himself out of the growing lust he was in. He knew he should try to act normal and continue their workout. But the sight of Nora and Ariana flushed with arousal was too tempting. Matt decided he needed to get them all somewhere more private.

“Hey, um, how about we head to the sauna to sweat it out for a bit?” Matt suggested, trying to sound casual. “This pre-workout has me feeling pretty wired ... the heat might help take the edge off.”

Nora stretched her arms overhead. “Oh yeah, my legs are so tight from those squats.”

Ariana nodded, rubbing her neck. “The sauna sounds perfect actually. My whole body is feeling tense.”

“Great, let’s head over there,” Matt said eagerly, leading the way.

The sauna was empty when they arrived, much to Matt’s delight.

As they approached the sauna, Ariana said “Hey, I need to run to the bathroom real quick, but go on in and I’ll catch up. Be right back!”

Nora and Matt exited the locker rooms wrapped in towels after changing out of their gym clothes.

As they approached the sauna entrance, Matt couldn’t help admiring Nora’s fit physique even with the towel covering her.

Matt adjusted his own towel discreetly, hoping Nora wouldn’t notice his body’s reaction to seeing her in just a towel.

Once inside the sauna, they sat down on opposite benches. Nora shifted on the warm wooden surface, adjusting her towel to make sure she was fully covered.

“It’s really warm in here already,” Nora said nervously, a blush spreading across her cheeks that had nothing to do with the heat.

“Yeah, feels nice though. This should help relax us after that weird supplement,” Matt said. But all he could focus on was Nora’s perfect legs and the thought of what lay between them under that towel.

Matt stood up from the bench he was sitting on and moved to sit right next to Nora. She tensed up as his thigh pressed against hers.

“I like this spot better, hope you don’t mind,” Matt said casually.

Nora shook her head, not trusting her voice at the moment. She was extremely aware of Matt’s firm, muscular leg against her own. She resisted the urge to rub against it for some relief.

Matt looked at Nora, their faces just inches apart. “Crazy how that pre-workout had such an effect, huh? I still feel all tingly.” He placed a hand lightly on her upper thigh as he said this.

Nora inhaled sharply at his touch. “Yeah ... really weird...” she breathed out, squeezing her legs together tightly.

Matt kept his hand on Nora’s upper thigh, gently stroking with his thumb.

Nora nodded, shifting under his touch. “Mmhmm...” she murmured. She was extremely aroused but hesitant to act on it.
