It had been a full week since the night that Tara surprised Cory with her shirt bursting trick.  The first few days felt particularly long for Cory, they seemed to drag on as he completed chore after chore for his mother.  Each day crawled along as the 15 year old not only physically watched his mother's muscles grow slowly before his very eyes, but literally felt it occurring day by day with his very own hands, each and every muscle hardening underneath Tara's soft skin.  Every day Cory witnessed Tara lift heavier and heavier weights, and noticed more and more finished textbooks piling up.

After the first couple of agonizingly slow days, Cory began to adjust to his new life.  While he wasn't particularly thrilled about his new living arrangements, Cory had to admit that life wasn't all that terrible.  He had finally learned how to mentally tune out his mother working out near him while he played games, finding himself able to enjoy them once again.  He also started experimenting with his cooking, taking pride in his ability to make a wide variety of dishes.

Then again there was something in particular that was nagging away at him. Sure, he still hated the idea that his mother was way stronger than him.  Sure, he couldn't help but be a little unnerved at seeing his mother tear through textbooks in a handful of days that would take his high school class an entire semester to work through.  Sure, he naturally wanted his mother to stop... improving... As selfish as that may be.  But, what really started to bother him was seeing his own health deteriorate slowly.  

It wasn't unusual for Cory to pack on a few pounds and grow a bit chubby over the course of the summer.  In fact, it had become a ritual of sorts for him, almost a complete reversal of the societal norm of fattening up a bit in the winter and slimming down in the summer.  Cory historically lounged around playing games during the summer, gaining a few pounds, and worked it all off at the school gym after the summer ended.  This summer however, was different.  Cory felt tired, achy, and all around run-ragged.  He knew that he lost the bet, which was his own fault really, but he needed to swallow his pride and admit that he was wrong.  He needed some healthy food.

Tara was finally home from yet another shopping extravaganza.  As always, she brought in all of the goods herself, almost as if to showcase that the old days of begging Cory to come outside and grab a few grocery bags were long gone.  After watching Tara bring in even more supplies than last time, Cory put away everything his mother bought while she went into her room to unwind with a shower and change of clothes.

After half an hour had passed, Cory had finally finished with his task.  Suddenly he heard a strange clicking sound coming from his mother's room.  A very familiar clicking sound...  Tara's bedroom door burst open, revealing her to be wearing only a skimpy bikini and high heels.  Every muscle in Tara's Olympian physique was on full display, not that she had been particularly modest lately anyways.  Even though he had some time to become used to the idea of his mother being so incredibly muscular, it still caused Cory a bit of shock whenever he saw her in that bikini.  In fact, Tara's musculature was even more intimidating now thanks to the expensive looking high heels.  Her entire lower body seemed to be propped up, causing each muscle to bulge out even further.  

As Tara confidently strode towards her son, a shocking revelation overcame him.  He was looking... slightly UP at her.  For the first time since he hit puberty, Cory was actually an inch shorter than his mother.  

"Surprised?" Tara asked with a devious smile, easily noticing how surprised her son was.

"Since when..." Cory began

"Well, to be fair it's due to the heels." Tara explained.

"But you were never taller than me in heels before!" Cory shot back.

"True.  There's no denying that I am indeed getting taller."

"But... how?" Cory's eyes grew wide with a mixture of curiosity, envy, and... fear.

"Whether it's the muscles, nutrients, stretching, I really don't know." Tara started.  "Honestly, according to most doctors and medical journals, I really shouldn't be getting taller... And yet I am."

Cory gulped loudly.

Tara chuckled lightly.  "And I have to admit, I really like it, being up here.  Must be nice for you to be this tall all the time, huh?"

All Cory could manage to do was nod in agreement.

"Reminds me of the good old days.  Back when you were the shorter one.  You used to be so much nicer...  Then you became a man, and an arrogant one at that."

Cory blushed slightly out of shame.  He hated to admit it, but she was right.  If Tara hadn't become such an unstoppable superwoman over the past month, he would likely be completely ignoring his mother, unwilling to give her the time of day.

"I know things seem rough right now Cory, but I promise that it'll be better for both of us in the long run." Tara said genuinely, kissing her son lightly on the forehead like she used to when he was younger.  

"I hope you're right." Cory responded, dubious to his mother's claim.

"Well, I have to admit that you've really gotten it together over the past week.  You've haven't caused a single infraction since THAT day." Tara said, smiling as she placed her hands on her hips, playfully reveling in her dominant physique.

Cory shuddered slightly at the thought of that day two weeks ago.  The day where everything he did seemed to cause a dreaded "infraction".  It was unbelievable to Cory how incredibly effective the threat of his mother growing stronger at a faster rate was.

"I've thought it over, and I have to admit I was a bit too harsh back then.  Sooo, since you've been such a good boy, you ought to get a reward. Is there anything in particular you'd like?"

Cory's eyes grew wide.  This was his chance.  He could ask for her to reduce his chores, or maybe let him sleep in later.  No, that wasn't exactly what he wanted.  Cory hated to admit it, but it was finally time to start listening to his body.

"Umm...  Well..."  Cory started nervously.

"Come on now, I know that I've been a little intimidating lately, but feel free to ask for anything."

"Can I uh, have some healthier food?" Cory asked.

Tara was genuinely surprised, and... impressed.  A smile formed on her lips.  "And why's that?  Do you want to have nice big muscles like me?" she asked, flexing her massive bicep.

Cory shook his head.  "No, I just feel like I'm getting... fat."

Tara didn't want to be cruel, but she couldn't help but snicker a little.  "Cory dear, you were getting fat before any of this happened at all."

"I know." Cory responded.  "It's just that, watching you get so... FIT... well..."

"Aww, you're finally realizing the importance of a good diet!" Tara playfully interrupted.  "Well, I still can't let you have any meat or protein powder, but I can certainly start letting you eat healthy."

An awesome wave of relief washed over Cory.

"You should also start doing some cardio.  That's how the popular girls at your school stay thin, right?  How about you join me on my runs?" Tara offered with a playful grin.

Cory gulped.  "Mom... we both know there's no way I could keep up at all..."

"Yeah, I know.  It would have been pretty funny though, watching you chase after me..." Tara mused.  "But you're right.  How about this. I'll allow you to use the treadmill downstairs during your free time."

"Will that help?"

Tara nodded. "Of course.  Not to mention, that's a state of the art treadmill, and I'm sure by now you know just how well high tech machines can help sculpt your body." she said with a wink.  

"Hmm, sounds good." Cory responded.  While he would have preferred being allowed to build up his muscles, Cory had never planned to workout during the summer in the first place, so it wasn't like this arrangement was any worse than the way things would have been.

"Alright, enough of that." Tara started. "You've got to get busy making a protein packed meal for me, and a vegetarian dish for yourself!"

"Yes ma'am!" Cory enthusiastically responded with a smile.

While Cory was already starting to enjoy experimenting with various dishes and recipes, he was now truly looking forward to testing out all sorts of crazy vegetarian dishes for himself.  Never before in his life was he so enthusiastic to eat vegetables.


One Week Later


As the rest of the week passed by, Cory slowly became further adjusted to his new way of life.  While running on the treadmill was monumentally difficult at first, after a few days his body began to adapt.  By the week's end, he finally had some semblance of stamina, and found that he was much more energetic than he had been earlier.  He had also found himself able to practically fully tune his mother out while he was playing video games.  In fact, Cory had become so entrenched in his daily routine of chores, gaming and now running, he had barely paid any mind to his mother's transformation.  While  two weeks ago Cory agonizingly realized every minor change in Tara's physique, he now somehow had little idea as to how she was progressing.  Even when he was wiping her down or massaging her, his mind was far off, thinking of how to defeat the latest boss he encountered in Dragon Effect, or how to get a higher kill/death ratio in Call of Battlefield.   As a result, he moved through the day in a zombie-like daze, albeit a rather content one.

That was, until, exactly one week since the evening his mother started letting him eat vegetarian...

Cory was in the middle of a gaming session while his mother dutifully exercised alongside him.  Suddenly, a tremendous crashing noise came from beside him, startling him from his game.

"Ooops!" Tara yelled out.

"What happened?" Cory asked, pausing his game.

"I underestimated just how heavy that was, and didn't place it down carefully."  she explained.

Since the machine featured thin plates that were super-magnetized, Cory had no real way of knowing how much weight she was up to.  "Jeeze, how much weight was that?" he asked.

Tara couldn't help but smirk.  The last time Cory was updated on Tara's weight lifting progress was two weeks ago, during their contest, back when she could "only" curl 60 pounds with one arm.

"Just a mere 110 pounds, it felt so light I honestly forgot how much weight that really is."  Tara nonchalantly explained.

"Ah, is that what you're up to with two hands now?" Cory inquired.

Tara couldn't help but giggle.  "Don't be silly Cory." she proceeded to press a few buttons on the machine's interface.  "There.  Now we're up to 125 pounds." she explained before grabbing the handle with one hand and curling it upwards, showing only a moderate amount of difficulty performing the action.

"No way..." Cory started.  He knew that he really ought to not question his mother's abilities, but this was outrageous.  Even the biggest, toughest jocks at his school couldn't lift that much with one hand.  Of course, he had seen videos on the internet of massive guys lifting that much, but even his musclebound mother seemed small in comparison to them.

"What? Don't believe me?" Tara asked with a light giggle and a wink.  "Come here and see for yourself!" she said before putting the weight down and stepping away a few feet from the machine.

Cory audibly gulped.  He vividly remembered what happened the last time he didn't believe his mother in regards to the amount of weight she was lifting.  Then again, that was 60 pounds, a number which, while incredibly high for a woman, at least seemed somewhat possible.  He got up and moved over to the machine, glanced over to the display, which clearly displayed "125 lbs", and proceeded to grab the handle with one hand.  Immediately after trying, Cory knew that there was no possible way for him to lift the weight with only one hand.  

Tara couldn't help but laugh a little.  If he had difficulty lifting 30 pounds last time, how could he possibly hope to even budge this much weight?

It has to be a trick... Cory thought to himself.  Maybe the weight was divided amongst two cables?  Yeah, that had to be it.  He grabbed the handle with both hands and pulled with all of his might.  Despite trying as hard as he could, Cory was unable to budge the weight whatsoever.

"Easy there tough guy, don't want you to get hurt now." Tara said, moving closer to him.

Cory glanced over and realized he'd have to look up at her again.  She really liked wearing those heels all day lately, huh?  As Tara drew closer, he couldn't help but realize how much... wider she was than him.  Well, wider everywhere except for in the waist.  Her shoulders especially were significantly wider than his, giving her frame a much more imposing shape than his own.  Although... Tara's wide upper-body was almost necessary at this point.  While he didn't intend to, Cory couldn't help but notice that even her breasts had been growing.  In the past Tara always had a moderately sized, yet perky bust, but now she was at least a C cup... most likely a D.  And not only were her breasts larger, but she had impressive, visible pecs underneath that pushed them up to superhuman proportions.  He had to admit, if it didn't belong to mother, he'd be seriously aroused by this body.

After Tara closed the distance, she placed her hand on top of one of Cory's.  "Here, let mom show you how it's done." she said softly, as she brought both her son's hand the handle up, lifting the tremendous weight with relative ease.

"H-h-how is this even possible?" Cory asked, unsure of what emotion to even feel at this.

"I know, it's pretty surprising huh?" Tara asked rhetorically.  "I mean, don't get me wrong, I DO have some pretty impressive guns." she flexed her intimidating right arm for emphasis. "But let's face it, this is only a little over 15 inches right now... No way that a regular human with biceps this size could curl so much weight."

Cory instinctively reached over and placed his hands on Tara's tensed arm.  "It's..." he cut himself off as he squeezed down.  He had never felt anything so incredibly hard before.  Sure, Cory had felt her arm every day during his massaging sessions, but she had never flexed it for him like this before.  And yet... despite how incredibly dense the muscles beneath were, her skin was still as soft as ever.  Neigh, her skin was even softer than ever thanks to Cory's nightly application of the best lotions money can buy. "It's... even harder than steel."  he said in disbelief.  With muscles this dense, it was no longer a surprise that Tara could lift so much weight.

"Hmm, ONLY harder than steel?" Tara asked, playfully disappointed.

"I mean..." Cory started

"Oh, it's okay, this just means that I have a lot of work to do!" she enthusiastically responded.

"What..."

"Being harder than steel isn't nearly good enough.  I'm going to become so hard that diamonds will seem soft in comparison."

Cory gulped again.  He was unsure how to feel.  On one hand, he was jealous, envious, and upset that he wasn't the one with such incredibly powerful muscles.  On the other hand, he couldn't help but envision his mother getting even harder and stronger.  It seemed almost... natural that this was happening.

He quickly shook himself out of his daydream, and looked down, thoroughly examining Tara's lower body.  While her upper body was impressive, Tara's legs were downright intimidating.  They were practically miniature tree trunks of chiseled muscle.  

"They're even harder than my biceps, in case you're curious." Tara explained, almost reading his mind.

Cory looked down further and noticed something that shocked him even more - his mother was... barefoot!  He immediately looked back up, reaffirming that she was indeed an inch taller than him, and back down, double checking that this wasn't a trick.

"You... aren't wearing heels?" Cory asked nervously.

"Hmm?  Of course not silly.  I'm surprised it took you so long to notice."

"But..." Cory started. "That means..."

"Yup. I'm 5'11" now!" Tara triumphantly exclaimed.

"How tall are you going to get...?" Cory asked meekly.

"No idea." Tara said. "Honestly, like I said a week ago, I really shouldn't be getting taller at all.  Then again, I shouldn't be this strong either.  Personally, I hope this continues, don't you?" Tara asked with a playful laugh, going onto her tip-toes to add a few inches over Cory to reiterate her newfound position.

"You really are turning into some kind of superwoman, huh?" Cory asked, completely dumbfounded.

"You're finally starting to understand!" Tara responded warmly with a smile.

Suddenly, the two of them were interrupted by the phone ringing.  "That's odd..." Tara said quietly "Very few people know the number to this house... and they all know that my brother isn't even here right now..."

She made her way over to the ringing phone and picked it up.  "Hello?  This is Tom's sister, Tara speaking..."

"Hey there sis', how's the vacation house treatin' ya?"

"Oh, hey there Tom." Tara's voice was tinged with feelings of surprise, annoyance, and... playfulness.  "It's going well."  She looked down at her bicep, which was positively bulging with the slightest amount of effort.  "It's actually going really really well."

"Great! Thing is Chloe's been buggin' me about not vistin' family enough... So I was thinkin' that she, me, an' the kids could come over and visit.  Maybe fire up the grill, eat some of those steaks I left for ya?"

"Oh... sounds great." Tara responded, thinking the situation over.  "Actually, it sounds wonderful." a playfully cruel smile come across her mouth as she began to realize how incredibly powerful she was now. "When are you coming?"

"Oh.. I'm thinkin' next week?"

"Sounds fantastic.  I can't wait to see you!" Tara responded enthusiastically.  "Well I've got to get going, let me know when you're on your way!"

"Sure thing sis, seeya in a week."

Tara hung up the phone before laughing lightly to herself.  As much as she was grateful for her brother's generosity, he was long overdue for a lesson in understanding just how powerful women can be... And she had an entire week to get ready.


- To be continued.
