MythBusters: Growth Serum
By Katrina Zwicker

Brwaaap! Brwaaap! Brwaaap! Brwaaap! Brwaaap!  Her alarm went off.  With a mutter Kari rolled over and smacked it into silence.  The first bleary thought that went through her mind was "Time to kick some ass!"

Staggering out of bed she stopped halfway to the bathroom, suddenly remembering what today was!  They were starting filming for the growth serum episode!  A shudder of pleasure and anticipation wrecked her body and she was instantly awake and ready for the day.  She'd been looking forward to this for weeks now.

The Feminox Vitamins had been out for a while now and the results some women were enjoying were nothing short of amazing!  Problem was that only a fraction of the world's women were affected by the vitamins in the way they were supposed to be affected.  It turned out that only 1 in 100 million women enjoyed exploding with unheard of levels of muscularity.  Every 1 in 1 million women saw only minor increases in strength and muscularity, but only to the level of champion fitness models.  The remainder of women felt a surge in energy and an increase in strength but it wasn't significant.  No grown woman grew taller as promised.  

It did seem to affect women undergoing puberty however!  Middle and High schools were teeming with girls over six feet tall and with more muscle than any of the boys in school.  Even they followed the same ratios as all the other women, with the exception that they were all, already, champion female bodybuilders.  The 1 in 100 million was 18, cute as a button, 7'4" tall and pushing 495 pounds of solid muscle onto her gigantic frame!

Unfortunately Kari was in with all the remaining women who only experienced a burst of energy and an insignificant increase in strength.  It wasn't even enough to beat Grant at arm wrestling and he's a total noodle boy.   She dressed in knee high boots, a plaid skirt, black tank top with a punk bracelet and a few necklaces.  She put her hair up with two clips and examined herself.  Yep, cute and badass!  She flexed her arm where a miniscule ridge tightened up and sighed, not quite bad ass enough…

In recent weeks there had been rumors flying that there was a slow growth option using the Feminox Vitamins as a serum instead.  It was supposed to be permanent but take about a week for full results, and you had to take the serum dialy, flooding your body with it.  It apparently also helped if you lifted weights while being treated.

It was also, supposedly, very easy to make.  You grind up the vitamins; combine them with a few choice ingredients, perform an alcohol based extraction, centrifuge out the detritus that the Feminox manufacturers had included and voila, female muscle and height growth serum!  All you needed was the right equipment and a background in organic chemistry.

They had brought in a grad student from Berkeley who seemed a bit over enthusiastic, and when she arrived at the shop she saw that he already had everything set up for the shoot.  They filmed the introduction to the episode and Kari could barely contain her excitement at the possibility of becoming a tall muscular kick ass Amazon!

They started out by getting a baseline for Kari.  5'7" 130 pounds, 10" arms, 15 pound bicep curl, 45 pound bench press, and 100 pound squat and so on…  Then they filmed and followed along as Brian, their chemist, created the serum.  They had paramedics on standby in case the serum somehow poisoned Kari.  She knew it was a risk but given the potential benefits she was willing to go through with it.  Even their insurance agency said that this wasn't the craziest thing they'd approved the MythBusters to proceed with.

Creating the serum took three days.  During this time they documented the process and Kari got more and more antsy. Actually on day two of the serum creation process Kari, Grant and Tori had a heavy chunk of metal they needed to move for another Myth.  It was just heavy enough that the three of them could barely move it together.

"You know, if that serum works I'll be able to lift this up all by myself…?  With one hand…"

Grant and Tori both looked at her with shocked and somewhat worried expressions.  "I can't wait!" Kari followed up after her comment had sunk in.

The day of the test finally dawned and she dressed in her blue patterned dress with leggings because she had no idea what to expect.  She didn't want to destroy her kick ass wardrobe.  Once she arrived at the workshop they started right away.  She received the first injection and immediately felt a rush of energy flooding her body.  She also felt like all her muscles were tightening and contracting without her wanting them to.  Everything clenched tighter and tighter to the point where she couldn't move and it was actually becoming quite painful!  Then, suddenly all her muscles relaxed at the same time and she felt instant relief.  

It was obvious on camera that something had just happened so she was asked to describe the sensations.  Nothing seemed to happen for about 30 minutes then she felt her muscles flex and tighten again!  This time it was a bit more intense and lasted longer.  Then when her muscles relaxed she was suddenly very hungry!

Scarfing down a huge second breakfast she went through two more contraction and relaxation phases, each stronger than the last.  After the fourth cycle she noticed that she was already noticeably buff.  Not muscular yet but she was definitely developing definition in her muscles!  She was also eating lots of food regularly in order to fuel her growing body.

One part of her transformation that she wasn't sharing with the camera and crew was that every time her muscles clenched, her vagina did the same thing!  Every cycle the pleasure that her strongest sexual muscle created built and built and built!  Finally when everything relaxed she would enjoy the release of orgasm after orgasm! She was hard pressed to conceal this from everyone around her but the pleasure she received from her growth, and the obvious results she was seeing after only a few hours made it totally worth it!

She also felt that about once every hour throughout the day that she had to stretch.  This felt like the kind of stretch you do right after you wake up, but every time she reached for the ceiling in a stretch her body felt totally relaxed and at home in her skin again.  The cycles of stretching and tensing continued all day!  It was quite painful and she was ready to crash by the end of the day.

It wasn't until quitting time that Kari realized she was now looking Tori straight in the eyes!  She had grown about four inches taller!  They put her through the round of measurements and found that she was now 5'11" and 175 pounds.  Her arms were now 14" in circumference allowing her to curl 30 pound dumbbells!  Her bench press was at 120 and her squat at 250.  She had more than doubled in strength in one day and grown quite a bit taller!  It seemed that there was some truth to this Myth after all.  The key would be her measurements in the morning because the Feminox Vitamins always wear off overnight…

She was so excited she went to her usual gym that night and went through a full round of weights pushing herself even more than she did at the shop.  It felt so good to finally be strong!  She didn't have to isolate herself to just the cardio machines, she could actually wander into the free weights area and discovered that she could kick ass in yet another way!  She noticed that there wasn't a single other woman pushing what she was pushing.

She couldn't wait to see herself in the morning and especially to receive her next injection!

My apologies for maybe coming off as lazy or inappreciative but I am to approve whether or not this may be allowed in our group galleries and I'm short on time so I must ask directly...does the "Gentle Giantess" that is the main focus of this story abuse her power and use it to ends which anyone may consider evil and/or abusive!?
KittyKatTrina Featured By Owner Jun 17, 2013  Hobbyist Writer
Kari definitely won't be abusing her power...!
