She knew she looked her best, or would at least, but she'd still never done a product presentation like this before. "I'm Dr. Maraja, but you can call me Jack. I'm here to demonstrate my latest product for consideration by the labs, Iron Foundation."
She took a deep breath, backing away from the camera to a well lit gym area, with a large tub of something thick and white off to one side, a painter's palette stored next to it with various pigments piled on. "Iron Foundation is my newest formulation, already patented, and stands posed to obsolete every other makeup base on the market. It goes on smooth to both skin, scale, and denticle, spreads easily, holds color well... and has... many health benefits."
Jack crossed her arms awkwardly under her chest, fingering her elbow fins a little bit and wondering how wide it was okay for a shark girl to smile. She wasn't usually self conscious, but appearing in a bikini for a board of directors just didn't feel right. She had to be showing as much skin as possible though, the point was to actually demonstrate a skin cream. So a red bikini top that barely covered her nipples and a bottom that -didn't- hide her whole package were unavoidable.
"I've invited an assistant here today to help me demonstrate just that, he's going to do my makeup and apply various 'test' forms of the foundation to my body to show the potential coverage even on something as difficult as tiger shark skin, with the stripes and roughness. And... you'll see what else it can do in the process."
You waved to the camera and glanced back at your nervous shark friend. Jack really wasn't Miss Gregarious and parading herself like this was way out of character but she had to show off her new invention. She had talked for hours about the stuff but you understood it mostly to be some kind of topical steroid that could be applied to specific body parts. You snapped on a pair of latex gloves and dipped one hand into the tub then turned to look at Jack.
"Where do you want it and what are we hitting first?" he said quietly looking at the shark as he rubbed the stuff onto both gloved hands.
"Let's start with my right arm. Arms have a showy pump, and it'll make for good contrast with my left before I even out. Try using the white and orange to cover up my stripes for this one, give them a nice neutral look to start with..." Jack nodded, giving directions as she sat on the weight bench. She held her right arm out for her assistant to take, while her tail brought over a few barbells her left arm began sliding plates onto.
You quickly began to rub the compound onto the shark's right arm. And per her instructions, began to coat the stripes on that arm until they were almost completely covered. The cream seemed to heat up as soon as it touched Jack's skin and dried almost instantly. The shark froze in loading the dumbbell and jerked for a moment as he saw her right arm twitch. The muscles in that arm clenched a little as a few new veins popped to the surface. It didn't look like it hurt but clearly Jack was feeling something as you applied all of the cream.
Jack was feeling a -lot- of something. Behind her glasses her eyes swam with stars as her brain got flooded with endorphins and her smile turned much more genuine, "oooOoh that feels so good..." she said breathily, doing as good a job as possible selling that she wasn't playing it up for the camera. "Thank you~" she teased, before rolling her now overloaded weight into her right hand, the bar groaning slightly from the 200 pounds of iron packed on top of it.
"Okay I already warmed up, for the safety conscious, but I've been using my new cream for a while now so I have to use a lot of weight to get going, please watch closely." Jack hoisted the weight, then sat in position for a preacher curl in front of the camera, holding it in her manicured claws before slowly bringing it up...
As her muscles -swelled-, veins standing out like drinking straws as the blood pulsed inside her and her bicep instantly peaked. "So you see..." she took deep breaths as she pumped, her peak rising higher and higher. "The foundation stays on, covering up my dark stripes..." and higher. She had to be 23 inches. "Even as my skin gets very stretched by the pump... you can..." 24 inches. "You can also see that thanks to the improved blood flow and nutritionally enriching elements, I..." 25. "My workouts are actually improved."
Jack stopped curling, a small set at her highest weight, letting the bar down before flexing both biceps to her side to compare.
"So as you can see, my right bicep is still unstriped, and despite glistening with sweat, has every millimeter of foundation in place, making I-F incredibly ideal for active lifestyles!" Her right bicep was -also- at least 3 inches higher than her left, veins standing out like under shrink wrap as she showed off the pump of her life.
You were spellbound as Jack pumped up. You could literally watch her arm growing with every heaving grunt. The shark was sweating now and panting. She also looked more than a little flushed but had a confident air about her that she had lacked when they started. Her eyes were fixated on the peak of that right bicep as her tongue wet her lips.
You weren't sure if the camera could see but she appeared to be a bit excited and was bulging her thong a bit more than she had been when they started. No clue if this was due to the cream, the workout, showing off her suddenly huge arm or some combination of the three. "Do you want to even that out?" you asked, looking at Jack and pointing to her left arm.
"Yeah, sure," Jack said much more easily, "Try a different pattern, something a little artsy to show off the potential designs, y'know, if you can." Now that she'd gotten the money shot, she was willing to be a little more loose with the footage, she'd be speeding it up and cutting it together later anyway.
Now she got to actually -use- it, make sure she got it over her whole body for a -proper- workout. The kind that made her practice having coregasms quietly in preparation for the video. "Actually, if there's anything specific you want to try with it yourself, you can go ahead."
You took her left arm and began doing just that, mostly making swirls that followed the major muscle groups, trying to apply the cream thickest on the major heads of each muscle, and painting lines that flowed with the muscle strands. Again Jack seemed to quiver and jerk a little as the cream was applied. Her eyes were locked on her left arm as you went to work and she seemed more focused than ever. Her bottoms were bulging worse than ever and she was breathing hard but that could be chalked it up to her just having grown her right arm to a massive size. Maybe the cream took a lot out of a person? That would make sense, but she had a very hungry gleam in her eyes as you stepped back from her left arm. "Feeling it absorbing?" you asked as he watched the cream quickly dry, the muscles in the arm tensing.
"OH yeah," if Jack wasn't on camera she'd be biting down on a plate to give her teeth something to do besides shred her lips as she was trying to resist. Instead she just quickly pushed through a series of curls on her other arm, pumping just as big as before and flexing again, showing off her now evenly sized giant biceps... before strategically flexing the recently painted one, making the massive ball of muscle shift back and forth across her arm, causing the swirls and eddies painted there to twist and billow like wind and waves in rudimentary animation.
"So as you can see, it works well for patterns as well as coverage, as long as you get the right additives. I know I'm not a color expert, that's the part that will be up to you! I'm just here to show you that one arm isn't a fluke." Jack pulled the weight behind her head, and started working out her triceps, not taking nearly as much down time the more her Foundation got her going, pumping up the other side as she turned to her assistant.
"Be a dear, why don't you pick next? Go wild."
You blinked as Jack all but demanded the next dose. She seemed a bit out of it, pumping her biceps over and over and over as if she was trying to squeeze a bit more size out of them. The shark was really panting hard now but didn't seem all that tired. In fact, they were going to have to do some editing because she was pitching a hell of a tent in her bottoms and the smell of horny shark permeated the room, not that the viewers would know.
Thinking about the next application, you slowly eyed the fit shark with the cannon-like arms. She needed a bit more balance, so Cody grabbed a double size dose and began to paint up Jack's quads thighs and ass. It was immediately obvious that the sensation was amplified this time as he felt her jerk under his fingertips. You weren't sure if it was the location, increased dose due to the larger area, or the buildup of the drug. Hell maybe it was all three. Jack's face screwed up with something like concentration.
Her legs went very stiff and began to quiver as she bit her lip far too hard. The trembling grew worse as you continued but it was a lot more skin to paint. When you at last finished up paining the muscles of the shark's ass, her bottoms now had a wet spot and were barely holding on. "Uhh do you need a breather or anything? You still ok?"
"No thank you..." Jack was fully flushed now, panting heavily, but her words stayed level as she focused. Legs and ass were next? Only one thing for it. She moved over to the squat rack.
She loaded up five hundred pounds.
"While I do appear flushed, this is largely due to my current heavy exercise, Iron Foundation is suitable for a -variety- of uses, and a user who keeps to minimal physical activity will experience far less vascularity..."
She loaded up ANOTHER five hundred pounds.
"While still keeping the heart benefits. Messing with blood flow usually has consequences, but in the past months of usage I have monitored my heart, and my resting rate has gone down significantly, even if racing at the time can be... relevant... not an issue..."
She started to forget the script as she loaded up a final two hundred pounds. With the 50 pound bar it wasn't just herculean, it was close to the world record.
You saw her load up the weight. Then load up more weight. Then MORE weight. "WAIT. JACK THAT'S TOO-" you tried to say as the shark shrugged the bar off the hooks with a grunt. Veins immediately rippled over her backside and down her legs. The moan that came out of the shark's mouth was less than chaste but she was still talking though her explanation of the finer points of the drug, at least until the weight landed fully on her shoulders. The mirror in front of the shark showed her front and the camera was behind her, pointed right at her ass.
The viewer could see both sides of the shark, and Cody could see her eyes were fixed on her legs with a manic intensity as she began to squat downwards.
Jack's legs bulged. Her ass squeezed so hard her tail got forced upwards, her cheeks flexing to the point that the layer of cushion she had on it got pulled to the side. Her legs swelled outward, inch after inch of thigh pumping in as calves sharpened to diamonds and her gastrocnemius held on for dear life.
Then she started moving upward. Slowly. Impossibly. With more weight than a woman had -ever- squatted before, she pushed.
She rose a foot.
She pumped up an inch.
She rose another.
Her veins pulsed to the side of a sink hose.
Her legs fully extended, the drooping bar hoisted up past her shoulders, as she locked it onto the notch of the top rack.
With a cry of "FFFFUCK!"
As her thong went flying across the room
You hit the record button on the camera to stop it just after barely dodging the flying thong as the camera and Jack's viewers did not need a fat view of Jack's pussy, balls, or cock which were now all in clear view. You had to stop as you looked back at Jack. She was holding onto the bar in the hooks like she would fall down if she let go and maybe that was the case. Her ass looked to have almost doubled in size and was forcing her tail out and up. Her thighs were so thickly muscled, she was going to walk with a permanent strut now, never mind finding pants that would fit. The shark's whole body was quivering and shaking as you moved over to the squat rack. "Jack you alright? Did you stain something? That was WAY to much weight!"
"Don't approach m-" Jack almost got out, but you had the -worst- timing. Walking up to her right as fourteen inches of shark cock finally lost their ability to hold back, Jack's orange-sized nuts seized as she came on the spot, oversized ropes slamming you in the chest as she moaned low and slow.
It was more than what you had ever seen from a pornstar, not just soaking you, but leaving fast, thick ropes across the floor between them, making a mess of the weights and gem equipment before Jack's hips stopped bucking and her cock stopped spewing.
It didn't get any less hard though.
"OKAY, there is one side effect," she said, coughing in embarrassment as she immediately looked for a towel for her assistant, "It's POSSIBLE that applying it to your cock MIGHT make it bigger, and MIGHT cause it to get too excited when you use it normally..."
You blinked as your life flashed before your eyes. The first gush of shark seed slapped you right in the chest and splattered everywhere.
There was some force to it, but it was more shock than anything as you fell over, watching as gush after gush of shark seed whizzed by over your head. If you didn't know better, Jack might have been TRYING to throw her ropes further from her grunting and flexing as she fired cum almost 10 feet across the gym. When she began to taper off a minute or so later, you caught a few more strays before rolling to the side as you looked down at yourself.
"What the hell do you mean MIGHT! I knew when you boned up at the start something was off. You have been rubbing that stuff onto that oversized pole of yours haven't you!" you said pointing at Jack's still hard prick.
"Yeah. I mean, I had to test, healthier skin, stays on through various flexing, improved blood flow... it was kinda the ultimate test. Just... now I'm a little... uh... like this..." Jack reached a hand down to palm her cock, the massive member well overflowing her digits as she bounced it with a bit of a thump.
"Not much of an afterglow, but I can fuck for hours. It's been a -trial- for my pants..." Jack trailed off, still a -little- loopy from cumming so hard... and slightly sore thighed even if they stayed pumped. "Sorry, I never meant to molest you, doing this. If you need a shower break that's understandable..."
She tossed you the towel, looking sheepish.
The towel only really ended up spreading the pungent and shockingly thick mess around. "Yeah I think that is in the cards," you said. "And I think you also owe me a new shirt," you said already peeling it off and tossing it in a nearby trash can. The tub of the compound was still open. You swiped a scoop in that hand and tossed the towel over that arm before standing back up. "Just give me a few and I'll be back. You might want to try and pound that tent peg back in and fight another set of bottoms so we can film some more." You said before heading towards the bathroom and shower attached to the gym.
"Sure thing!" Jack let him go, not even noticing the missing formula, before she went back to the weight bench to follow his advice. She probably -did- need to give her cock some more attention before it would go down. Fortunately, her fitness routine had -plenty- of benefits. She leaned back, balancing on her shoulders as she flexed her core, guiding her lower half into the air and positioning her waist over her face...
Before crunching down enough to get her cock past her lips, giving herself a self-suck. It wasn't -that- hard, at her size, admittedly, but she was still proud of getting good enough at the position to hold it on most surfaces.
Plus it was a great way to practice her tongue skills... and get to enjoy something pretty tasty on the side.
You missed the muscle bound self sucking shark show as he headed towards the bathroom to wipe the shark jizz off your front with the pilfered scoop of wonder cream. Turning the glove inside out to keep it safe as you stripped and started the shower. Scrubbing off quickly, you grabbed the latex glove with the cream and promptly pushed your rock hard cock into it like it was a condom, just outside the hot spray of the shower. The cool cream hit your shaft as you felt a jolt and buzz. It was almost eye watering in intensity as you squeezed the glove a bit to spread the cream around. A good bit oozed out the bottom and you grabbed the extra and rubbed it into your balls.
In seconds your package was completely coated as the buzzing in your shaft and balls grew in intensity. God had it felt like this every time you had painted Jack up? Veins popped up all over your prick as it jerked in your grip swelling and spreading your fingers. You began to pant and pump while your balls plumped and the fat shaft stretched past 8 inches. Jack hadn't really told you how much to use down there when you had scooped a whole glob of the stuff. Maybe you had used a bit much as you panted and pumped faster, the pressure in your growing balls increasing… It was getting harder to think the more you grew. And with somebody here to take care of you surely it couldn’t hurt.
You wanted more.
