Max gives it his all.

“You sure you’re up for this?” Max asked his friend.

“Yeah, I still got some gas in the tank, if you do, Maxi!” Jill assured him. “Let’s work up a good sweat!” Jill gyrated her hips playfully.

“Alright, once more unto the breach…” Max recited as he stepped towards his naked workmate.

Max carefully assumed the position you had just been in with the tall blonde. Underneath, Jill laid back and opened her legs for entry. She still glistened with your fluids, but that didn’t balk the salary man or his coworker. Max’s cock was already stiff from watching your demonstration, so he guided it into Jill’s juiced up pussy. It went in with ease and Max shivered from the sensation. Jill writhed a bit, feeling herself fill up again. It must have been a warm and natural feeling at this point because she let out a relaxed sigh as Max pushed inside.

You could hear the sounds of their bodies pushing together over the clanking of weights and pulleys in the background. Max started finding his rhythm and the slick sound of juices meshing became more steady and controlled.

“I can’t remember the last time I got this good of an exercise,” Max muttered, thrusting his hip into Jill.

“Your form’s much better this time,” Jill complimented as her body bounced against the weight of the large man. “I do believe you’re learning something! NNgh…”

“Oho… don’t be going on about an old dog and new tricks now…” Max retorted. “I still refuse to change over to the new filing system! I can’t find a thing with that system!”

“Oh Max…” Jill sighed, rolling her eyes. It felt like a long debated issue between the two.

“If I’m spending an hour looking for a file, that’s one hour lost from actually working on it!” Max complained. His thrusts became stronger as his resolve pushed him.

“Oh…” Jill moaned, “If only you could be this forceful in morning meetings, maybe they’d hear you out…”

“Ngh….” Max grunted. He was building up a good layer of sweat as they went on. “Ah.. damn, I lost count…”

“You’re past twenty, take a rest,” Jill said, helpfully.

“Ah…” Max panted, “Yeah, I’ll do that.”

“Fifteen seconds,” you instructed.

Max nodded and held his position on all fours over Jill as he caught his breath. He wiped the sweat on his forehead and chest then said to Jill, “Sorry I’m raining down on you like this.”

Jill laughed, “It’s alright. It’s actually good to see you giving so much into something. It’s been a while.”

Max chuckled, “Yeah, well I guess you can be a good motivator!”

“I’ve been taking you out to the gym for years and haven’t gotten you to do more than a sit up! It’s obvious that our friend, the coach, is the real motivator!” Jill replied as she gave you a look of appreciation.

You smirked and looked at your watch. “That’s fifteen seconds.”

“Put me back in, coach!” Max chuckled before sliding his cock back into position. The two fell into their rhythm with ease and were counting off the reps under their breath.

“Your technique really has improved!” Jill noted as each thrust made her massive breasts jiggle form the impact. “I can really feel you getting in me!”

“It’s a…” Max panted, “...ngh... good spot to be in!”

“Just think… mmm… where you would be if you had done this sooner… ahh...” Jill suggested as her body quivered from the last thrust.

“Well, if you’d… ungh… if you’d… nmmm…. done something like this…” Max gasped, breathing heavily, “I might have…”

“Ahh…” was Jill’s response.

“Even getting a gander… ngh… at these lovely… tits… huh...huh…” Max admired. “Those gorgeously stiff nipples… ahh…. I can workout to that sight…” Jill cupped her pillowy breasts and pushed them upward for her workmate’s benefit. “Damn, I could fall asleep in those…”

You noticed Max’s tempo slowing down as he took the time to admire his coworker’s ample bosom. You tapped your foot and told him, “Pick up the pace!”

“Ngh… yes coach!” Max begrudgingly obliged. He went back to thrusting, doing his best to keep proper form. After the twentieth rep, he pulled himself off his partner and lay on his back, gasping for air.

“Poor Max…” Jill empathized.

“You know the exercise,” you calmly explained to Max. “Twenty reps at increasing speed until you climax.”

“I’m going to have a heart attack before I get there,” Max complained.

Jill pursed her lips as an idea came up in her head. “How about I keep our coach occupied so he’ll be a little more lenient on you, Maxi?”

“I’d be in your debt, Jill!” Max replied.

“What exactly are you planning?” you asked with a raised eyebrow.

“Just looking to do a little workout of my own...” Jill said, touching her finger to her lips demurely. “Are you willing to help me out with it?”

Not one to deprive someone of a good workout, you smiled and said, “Alright, but Max still needs to do his reps.”

With almost a defeated sigh, Max said, “Going back in, coach!” He resumed his position and started counting off to himself.

You turned to Jill and asked, “So, what sort of exercise were you thinking of doing?”

Jill wiggled her finger for you to approach. You stood next to her and she reached for your cock. It had been recovering from the recent orgasm, but the touch of Jill’s long, feminine fingers around it made your lower member prick up. She firmly wrapped her fingers around the girth of your shaft and began to stroke it. It was in time to Max’s reps. You stiffened up quickly and as soon as you did, Jill leaned in and took it into her mouth. You exhaled sharply as the Amazon deep throated your dick in one thrust. Her head bobbed back and forth, going twice the pace of Max’s thrusts. You grunted and arched your back so that your hip jutted into Jill’s face. She cupped your balls and fondled them as she continued to blow you. The sides of her lips spilled saliva but she kept her lips wrapped around your pole.

“Twenty…” Max gasped, panting heavily. He remained on his hands and knees as he recovered, ready to go again in a few seconds. Jill pulled out as well, slurping up the saliva and juices before taking in big gulps of breath. Your cock was glossy with Jill’s spit, you couldn’t wait for her to get back on.

“Fifteen seconds,” you urged the two. They didn’t exchange banter this time. They were too focused on their exercises and their recovery. Fifteen seconds later, you called out, “Time!” and they went back to work.

You could feel the increased intensity coming from the two. Their chatter was gone and replaced by wet smacks and slurps going at a measured pace along with some heavy breathing. The pace was notably faster as each person had their own sense of urgency building up inside. The speed was going so quick that you could feel your own build up reach the edge. It was about to go over when Max muttered, “Twenty” and stopped. Jill stopped as well, leaving you aching for more. You had to take the next fifteen seconds to steel yourself for the next ****. It was turning into a workout for you as well!

Fifteen seconds later, the two workout buddies jumped back into their reps. There was a sense that things were nearing their conclusion as both went full **** into their exercises. Max was ramming his cocking into Jill, causing her entire body to shake and jiggle. The intensity of the thrusts meant that Jill couldn’t sit up like before, so she lay on her side with you on your knees for easier access to your cock. She had you down her throat and had given up on trying to keep double pace on Max. Instead, she was vigorously bouncing her head over your manhood so fast, her face was becoming a blur. The feel of suction on her dick only caused it to swell harder and you grit your teeth trying to hold on. Soon, you could feel different movements on your schlong. Jill was trying to say what you guessed were the words, “I’m cumming.”

Max may have deciphered the garbled noises as well, because he grunted back and made several fast, hard pumps into the woman before stiffening up and holding his position. Jill wriggled, then arched her back and tensed up as well. You could feel her body shiver around your cock and it sent a shiver up your spine, causing you to shoot off in Jill’s mouth. Jill took it in as she rode out her own waves of ecstasy. Her body undulated in time with her bobbing head. Max gave a few splotching thrusts into Jill to empty out his reserves before falling over on the tall Amazon and panting.

The buzz of orgasm slowly wore off and you could collect your thoughts again. You looked to Jill. She was spent and content, staring up at the ceiling. Your cum had spilled over the sides of her mouth, but she was too tired to clean herself up. Max was laid over her shoulder, still breathing.

With the exercise complete, you felt it was your duty to leave your protege with some duties to work on, moving forward. “Max, ” you said Max turned his head toward you. You could see his hips were still twerking into Jill’s oozing pussy, but didn’t seem bothered by the action. You continued, “I expect you to do this same exercise as often as you think you can!”

“We could work on it every day!” Jill suggested, still being thrust into by Max’s spent penis.

Max gave a long exhale and said, “I don’t think I’ll be able to come out every lunch… I got meetings and other priorities.”

You remembered that your powers only extended as far as those inside the gym, but you wondered if your influence would extend out as a power of suggestion. There was only one way to find out. You addressed Max again and said, “Alright, maybe you can do this exercise at work, just let people know you’re following my recommended regimen.”

Max gave it some thought, then said, “I’ll give it a shot, coach.” He gave a begrudging grunt and added, “Speaking of work… it’s best we head back! We’re late enough as it is!” Jill nodded and Max peeled himself off of her. “It’s been a pleasure, Jill!”

“Pleasure was all mine!” Jill replied. They pulled apart with a small slurp of Max’s cum soaked cock prying free of Jill’s slippery hole. It came out with a wet POP! Jill gasped and giggled at the sound and feeling. “You really got in there, good!” she remarked.

“Filled you up real nice too!” Max noted as he helped her to her feet. Jill’s snatch was coated with white, creamy fluid that dripped onto the mat. You got a towel to help wipe her down. The three of you then went about cleaning up your workstation, completely nude. Again, the rest of the gym goers took the scene as ordinary and uneventful.

Once you finished, Jill held her hands on her hips to assess the cleaning and said, “This was fun! I can’t wait to do it again sometime!” She then mused, “Maybe I should bring my husband out!”

Max gave a disappointed look that Jill caught. She smirked and took Max’s hand and held it up to her breast, making him give her a good squeeze. She murmured to him, “Rick’s into anal… and I’ve always had this fantasy of being filled in both holes at once…” she gave him a wink before turning to gather her things. “It’s just exercise, but I’m curious to know what it feels like to have two cocks exploding inside me…”

This lifted Max’s mood and he said, “Maybe I’ll ask Cristi if she’d come out too. We could meet up on the weekend for a group workout session.”

“That sounds like a great idea!” Jill agreed.

The two bid you farewell and headed off to the showers to wash up. You stood there, wondering what you could try next, looking around the gym that remained oblivious to the naked man standing around. Then, your eyes locked onto someone who had been watching the whole thing. It was Jaime.
