Ancestor’s Blessing, a female muscle growth story.

Despite being in their late 20s, the Egarty siblings, Edmund and Erin, followed the family tradition of spending St. Patrick’s day together.  The custom itself was quite simple, everyone in the Egarty clan who was of age would be united in a bar crawl of every pub in town.  Edmund and his sister were the only members of their immediate family who were in the United States, and as a result they would be the only members of their drinking party that night.

For Edmund, this meant another fairly awkward evening of far too many strangers presuming that Erin was his girlfriend, heavily minimizing his chances of finding someone to potentially spend the night with.  Erin on the other hand knew that her brother was going to be a downer for the most part.  Still, it was one of the only days of the year they saw each other, so they looked past any potential misgivings and prepared for a night on the town.

Erin was wearing a black tank-top with a short-skirt, showcasing her pale, toned body.  Edmund on the other hand wore a white long sleeved shirt with a pair of jeans.  Both of the Egarty children had the same fiery red hair, bright blue eyes and playful freckles on their faces.

“Been workin’ out sis?” Edmund asked, eying his sister up and down, taking note of her well-defined shoulders and triceps.  He had a definite hint of an Irish accent to his dialect, but it was apparent he had been thoroughly Americanized.

“Werk’s bin slack lately, cuttin’ everyone’s hours; so I’ve bin pickin’ up shifts unloadin’ at the dock.  Keeps me busy an’ helps make ends meet.”  Erin’s accent on the other hand was extremely thick, as if she truly embraced her heritage.

“Erin, I’ve told you time and time again that if you need help paying the bills to let me know…”

“Can it.” Erin shot him a dirty look.  Despite the wealth disparity between them, she refused to accept his charity – a matter of pride as she’d put it.

“Well, uh, for what it’s worth it looks like it’s doin’ your body good.” Edmund added.

Erin flashed a toothy grin before flexing her arms, causing a pair of small, well defined biceps to pop up “I guess you could say that. Anyway, enough flattery outta you.  Maybe you should be hittin’ the gym mister office boy.” she poked his somewhat doughy midsection and gave a playful laugh.

“Oh come off it sis, I’m still the man around here.” Edmund shot back.  Standing half of a head taller than her with a broader build and larger limbs, he had a point: even if Erin’s muscles were more defined in appearance, he was the undoubtedly larger and stronger person between them.

“Yeah, yeah, whatever Ed.  Let’s git this show on the road.”

1.) The First Bar

The first stop was a small, low-key bar that was nearly empty despite it being one of the most prominent holidays for alcohol consumption.  This was always the first place the Egarty’s stopped at during this particular crawl of the past few years.

“Have anything light on tap?” Edmund asked the barkeeper.

Erin shot her brother a dirty look.  “Really Eddie?  Yer gonna drink light on the yearly crawl?”

“Well… trying to watch my calories.”

“It’s saint paddy’s day!  That’s spittin’ on our ancestors’ grave!” Erin turned her attention to the bartender who was holding back his laughter. “Forget this lightweight, I’ll take the darkest, heaviest stout you’ve got.  A pint if you will.”

“Comin’ right up.” The bartender grabbed a hefty glass, filling it with a near-black liquid.  “Still want something light?” there was an air of condescension to his voice.

“Just give me a pint of any pale ale.”

Erin snickered, and the barkeep continued to hold back his own response.  A few moments later, both Egarty siblings had their drinks in hand.  “Well, cheers.” Edmund said, bringing his lighter beverage to his sister’s darker one. “Cheers.  To th’ ancestors” She responded, returning the motion, causing their glasses to audibly chink together.

Edmund took a swig from his drink before putting it down.  He glanced over and noticed his sister was flat out chugging the entirety of her beverage.  Gulp after gulp Erin continued to down the stout and a few moments later had downed its entirety without taking a break.  She confidently slammed the mug down.  “Ahh.  Good stuff!” She declared before letting out a small, feminine burp.  “Really good.  I feel like a new woman already.  Would order another if it weren’t for the tradition of one drink per stop durin’ the crawl.”

Feeling upstaged, Edmund took a large gulp from his own beverage.  He attempted to take another in the same gasp, but nearly choked on his beverage.  Spitting a bit out, he put the glass down and wiped his mouth.  Erin let out a teasing laugh that only a sister could produce.  She brought her hand up to her mouth in the process, which in turn caused a sizable, defined bicep to unintentionally stick out.

“Jesus Eri.” Edmund started, referring to his sister by a childhood nickname. “Not to beat a dead horse or somethin’, but your arm’s lookin’ jacked in this lighting.”

Erin looked down and observed the arm Edmund was staring at.  She was surprised to find that he had a point: it was looking more impressive than it ever had before.  Curious, she tensed it, causing a sizable, round ball muscle to rise up  further that wouldn’t be out of place on a fitness competitor’s arm.  “Yer right Eddie.  It IS lookin’ pretty damn good.”  She noticed a split in the center of the bicep’s peak which stroked her curiosity.  Reaching over with her other hand, Erin placed the fingers of her free hand into the divide in her muscle.  “Wow, never noticed this little crevice thing before.” She continued running her fingers along it.

After indulging in the sudden quality of her biceps, Erin moved back and produced a traditional double bicep flex; a pair of arms likely over a dozen inches in circumference sprang to life, complete with striations in the tendons connecting the muscle.  “Wanna feel?”

Edmund reached over and gave the limb a squeeze. “Good lord, this thing’s hard as a rock!” he was blown away by the quality and density of the flesh within his grasp.

“Yeah, I guess I didn’t realize just how jacked those unloadin’ shifts are gettin’ me.  Imagine if I start hittin’ the gym, I’ll make you look like a wee little lad!” she let out a thrilling laugh.  “Imagine me with big, powerful muscles.  That sounds like a lotta fun actually…“

A cold sweat broke out down Edmund’s back.  The thought of his sister’s fiery, confrontational personality with real strength behind it was something he didn’t want to imagine.

Erin’s voice cut in again. “Anyway Eddy, finish yer damn ale so we can hit up the next spot.”

Edmund forced the rest of his orange-ish beverage down.  The siblings paid their tab and prepared to leave for their next destination.  As they both stood up, Edmund did a double-take, was his sister taller?  He glanced down and was surprised to find that she wasn’t wearing heels.  Her exposed legs and back were also shockingly well defined as well.  Edmund found it strange that he hadn’t noticed these qualities in his sister’s body when they first met up.

2.) The second stop

The Egarty siblings arrived at the second destination of their alcoholic odyssey: a sports bar more lively than their previous stopping point.

This place was renowned for having highly attentive waitresses who would quickly bring you drinks while you played pool, darts, arcade machines or simply watched television.  Edmund and Erin moved over to a pool table and set it up so they could play a match.  After getting things ready, they started playing.  Erin took a quick lead, and Edmund had a difficult time catching up.  As the red haired woman stretched across the table with the pool cue in hand the muscles on her frame sprang to life with each motion.  Edmund was thoroughly surprised at just how damn muscular Erin looked.  He could’ve sworn that when they first met up for the evening she wasn’t that big.

A waitress came over and took their orders.  Once again Erin ordered “The darkest stout you’ve got” while Edmund opted for “Whatever’s popular tonight.”  A few minutes later they had their beverages in hand.

As Erin chugged the second brew of the night, she felt the same sensation of refreshment that accompanied her previous drink.  Edmund forced himself to try to chug his own brew, but at around the halfway mark he had to stop.  After putting his glass down, he glanced over at Erin who was still going strong and nearly spit his drink out: she looked huge!  Even huger than before!  With a few more gulps, Erin finished her mug and slammed it down with enough force that the container shattered, causing glass to fly all over the place.  “Shit.” Erin muttered loudly.

“So much for our game, eh?” Edmund noted.

“It’s not like ya had a chance of winnin’ anyways!”

Two of the waitresses quickly came over to examine the noise.  “Sorry girls.” Erin said, scratching the back of her head, causing a thick, powerful bicep to bounce in the process.

“You must not know your own strength.” One of the girls was looking over at Erin with visibly lust-filled eyes.

“I guess not…” Erin responded.  She brought her arms down and glanced at them, immediately realizing that they were definitely significantly larger than they were a mere few moments ago.

“Never mind the glass, give us a flex!” the waitress insisted.

“If you say so.”  Erin gathered herself and performed a double-bicep shot.  The muscles that popped up were fitting of a physique competitor or lightweight female bodybuilder.  They were also incredibly well defined, with the split that Erin had played with earlier deepening even further.

The waitress reached up and placed her arms around Erin’s bicep.  Her eyes grew wide as her fingers fondled the powerful limb.  “I’ve never felt an arm this hard!” she cooed. “You there, come over here for a moment.” She was referring to Edmund.

“While you oogle the customer, I’m going to go get the manager about this mess.” The second waitress chimed in, clearly unimpressed with the entire situation before taking off.

Edmund complied with the first waitress’s request and came closer to the two girls.

“Is she your girlfriend?” The waitress inquired.

Both of the Egarty siblings quickly blurted out a “No! We’re siblings.”

“I’m Erin and this is my brother Edmund.” Erin explained.

“Ooh.  Well, anyways, let me see your arm Mr. Edmund.” The waitress demanded.

With some degree of reluctance, Edmund flexed his right arm; It was mostly disguised by his long-sleeved shirt.  The waitress reached up and grabbed hold of it.  “Not that bad, but hers is way harder!” she squealed.

It was at that moment Edmund realized that Erin was now nearly the same height as him.  A familiar cold sweat broke out on the back of his neck.  “Well… earlier today…”  Edmund muttered as he started trying to formulate his thoughts, but he realized how insane it would sound.  The remainder of his sentence played out in his head: Earlier today she was much smaller than me, and her muscles were only slightly toned.  This sudden growth spurt occurred during the past 30 minutes.  Nobody would ever believe that, especially if Erin pretended he was lying.

“Well, what?” Erin asked, cocking an eyebrow.

Fortunately for Edmund, he was saved by the second waitress returning with her manager.  He was a portly man in a business casual outfit.  “I’ve heard about the accid-” he cut himself off as he caught full site of Erin’s powerful, muscular body.

“Well, now what?” Erin asked, growing tired of all these people cutting themselves off.

The manager shook himself.  “Sorry, I’m just…”

“Not used to seeing a powerful woman?” Erin added.

“Something like that.  Anyway, this may sound harsh, but those mugs are worth $30 each to us.  We’ll have to ask you to reimburse the price.”

Erin let out a long sigh.  “Bloody ‘ell.  That’s half a shift’s wages after tax!”

Edmund interjected. “I’ll take care of it.” He added producing his wallet, his deft fingers ripping a credit card out.  “Put our drinks on this too.” He handed the card to the portly man who nodded and took it out back.  The second waitress dispersed to resume her duties, while the first one continued to linger.

“Tell me miss, you really must, what’s your like… routine to get all muscley?” The waitress asked, clearly enamored with the muscular woman.

Erin was taken aback for a moment.  She had no real routine.  She also couldn’t quite just mark this up to magic, it’d be too unbelievable.  “Well lass..” She started, continuing to think of what she should say. “Strong, dark ale.  Hard work and an honest heart.  Th’ ancestor’s reward those who follow that path.” Erin concluded, giving her admirer another flex, bringing her arm down so the waitress could easily wrap her hands around – which she quickly did.

“Oooh… such sage advice!”

Edmund rolled his eyes.  Erin wasn’t lying, but it completely left out the fact that all of her muscle growth came spontaneously in within the past hour.  The manager returned with his card and a receipt, handing it to him.

“Does this mean you’re going to be taking off?” The waitress asked with a distinct sadness in her eyes.

“Indeed it does lass.  Eddy and I are on a bar crawl tonight in honor of Saint Paddy’s.” Erin explained.

The manager started to turn away, but was interrupted by the waitress.  “I’m going to cut my losses and leave early tonight.  I don’t want to lose this magnificent woman!”

The manager uttered something unintelligible under his breath, but felt compelled to comply with the request.

With that, the Egarty siblings left the sports bar with a third member in their party.  This dynamic forced Edmund to keep his lips sealed about the bizarre turn of events that were occurring.  The last thing he needed was for this girl who was now physically clinging onto Erin to think he was a crazy person for believing in magic.

3.) The third stop

The third bar on the Egarty’s crawl was a dingy place full of fairly rough regulars.  As they entered, an ongoing arm wrestling competition caught their attention.  A small crowd had gathered, spectating the match.  An extremely large man with a great deal of fat surrounding his sizable muscles had locked hands with a smaller competitor.  Within a matter of moments the larger man brought the smaller one’s hand down to the table.  A few of the onlookers cheered.  Two girls came in close to the large victor, crooning about how strong he was.  One spectator announced that “Big Bill has defeated his sixth competitor in a row!  Someone get this man a drink!”

The waitress looked up at Erin “You should totally go kick that guy’s ass!” she giggled.  “I’d love to watch your big, strong muscles pump up and take his fatty fleshbags down.”

“I like the way you think lass!” Erin replied with a grin.  “Eddy, go get our brews from the bar.  As you know, ask fer the darkest stout they’ve got for me.”

“Yeah, sure.” Edmund agreed making his way to the bar.  After flagging down the tender, he decided to order the same drink as Erin.  Maybe it’d have the same effect on him?  Yeah right, fat chance of that.

A few moments later, Edmund traded cash including tips for the brews and with them in hand turned his attention to finding Erin.  It didn’t take long, as she was actively engaged in arm wrestling the massive man.  Her large, round shoulders and bulging arms were engorged to new heights as they strained to prevent Erin’s hand from hitting the table.  It was apparent from the beat red expression on both of the competitor’s faces that they were in a standstill.

“Come on Erin you can do it!!” The waitress cried out.

Edmund considered withholding Erin’s beer and seeing if she could win, but between sibling loyalty and a curiosity to affirm that it was the brews that were enhancing her physique lead him to decide against that.  He brought the beer over  “Hey sis, think you can multitask?”

Erin’s eyes lit up even more than their typical brilliance as her free hand reached over and grabbed the beer.  She brought it to her lips and took a massive chug.  Immediately, every muscle on her body instantaneously gained well over an inch of circumference.  Erin quickly gained some ground in her match, but her opponent continued to hang on.  The red-headed beauty took another gulp of her drink, and her muscles expanded even further.  Her opponent is now on the verge of absolute defeat, and with a third glug, Erin’s body muscles grow to the point where he cannot resist their power.  With a triumphant motion, she slammed her opponent’s hand down.

The small crowd around the arm wrestling table was in an uproar.  Who was this woman who just defeated Big Bill?  Did she just grow while drinking a beer?  Was drinking during the competition even allowed?

Erin stood up to her new now taller height.  She brought the mug to her mouth and with a couple large chugs finished it off, spurring on another burst of growth.  The crowd was practically in hysterics over what they were seeing.  This woman really was growing right before their eyes!

Erin flexed her now massive biceps.  They were easily over 18 inches in circumference and would be the pride of practically any female bodybuilder, most male ones too.  She now stood at a hair above six feet in height, and every muscle on her frame was immense.  The tank-top that covered her at the beginning of the night was shrinking in comparison, and it failed to cover the bottom half of her thick, ridged eight-pack abs.  Similarly, her mini-skirt was now something of a micro-skirt almost entirely revealing her trunk-like legs.  Not only had her body grown larger, but Erin looked fiercer and more beautiful than ever before.  Her blue eyes were practically sparkling, and her luscious red hair had grown proportionately with her body.

The two girls who were swooning over Big Billy were now grabbing onto Erin.  Edmund began forcing his beer down, eager to get out of the bar before the attention his sister was receiving got out of control.  Erin could see her brother’s discomfort, and while she enjoyed the ooh’s and ahh’s of the spectators began to also worry that things could get out of hand.  “Sorry everyone, but my big brother and I have to continue on our holiday tradition.”  Her voice was loud and easily dominated the noisy building.  Her Irish accent seemed even thicker than before, as if she were truly embracing her warrior-woman persona.

“Let us come with you!!” both of the girls squealed.

“Very well lasses.” Erin replied warmly.

“Hey, us too!” a couple of young men shouted.

Erin considered their request. “I’ll take you.  Sorry to yer mate.” She answered, pointing to a very handsome, but somewhat small man.  His larger friend groaned before giving him a pat on the back and a thumbs up.

The party of now six people left the bar, heading off to their next destination.  Erin had placed her long, thick arms around the shoulders of all of her groupies – two on each side.  Edmund followed from behind, still trying to wrap his mind around the chain of events that lead up to this point.  Something else that struck him as especially nerve wracking was that each of Erin’s growth spurts seemed more significant than the last.  They still had two more stops on their crawl, and he wondered if she’d continue to grow at each of those too.

4.) The fourth stop

As Egarty siblings and Erin’s fans approached the fourth stop they were greeted by a small group of nervous looking people outside.  “You don’t want to go in there.” One of them said.

“And why’s that?” Erin asked, emboldened even moreso than usual thanks to her newfound strength and admirers.

“It’s a riot in there.  Huge fight broke out.  Probably going to have to bring in the whole police department in riot gear and tear gas or something.  Worst part is some good people are stuck in there, like the bartender.”

The group could hear the sounds of things breaking and people shouting from within.

“Sounds like fun.  I’ll take care of it.” Erin said with a grin.

“Ma’am, while you’re really quite, erm, impressive, I really don’t think-”

The man was interrupted by Erin giving him a playful shove aside as she walked into the bar.

Safe on the outside, Edmund, Erin’s fans, and the worried group of people listened intently.  They heard a voice yell out “Oy, who’s this steroid bitch?”  Followed by a tremendously loud smack and the man literally being thrown out of the bar’s door, landing him in front of the group.

Inside the establishment it was utter chaos.  It looked like a mosh pit from a metal concert had decided to all actually fist fight with one another.  Erin began blocking blows with her meaty arms absorbing the impact with their girth before knocking her attackers out with a swift jab to the head.  Despite her sheer superiority over the various fighters, there were simply too many for Erin to handle at once.  She formed a plan in her head and began fighting her way towards the bar.

Due to the massive difference in Erin’s physical prowess and those of the people around her, Erin’s journey to the bar was more akin to slowly wading water than the dangerous feat it should have been.  Eventually, she reached the stool and yelled out.  “Hey, barkeep!  I just knocked out a dozen of dese fools fer ya, how ‘bout you reward a lady fer her service?”

A large, muscular man emerged from a crouching position.  It was somewhat humorous to Erin that such a well-built person was cowering due to the ongoing chaos.  “Uh, what can I get for you?”

“I’ll make ya a deal.  Gimme two of th’ darkest, thickest stouts you’ve got, and I’ll clear this whole room out.”

“Ma’am, I really don’t know… I mean the police will handle it eventually…”

“You really want the cops comin’ here and askin’ questions?” Erin asked, cocking an eyebrow.  “Besides, ya don’t think I’m up ta the task?” she flexed her arms for emphasis.

“Alright miss, you raise a compelling point.” The barkeep produced two mugs and began filling them up.

As he attempted to do so, a random ruffian made a run towards him  “Oy! How about you share the booze!” he yelled out.  Before he could reach the bar, Erin had unleashed a devastating backhand to his face that sent him flying across the room in one swift motion.

“Damn Miss.” The barkeep responded, wide eyed.  He put both mugs down on the counter in front of her.

“If ya think that’s impressive, just wait.” Erin said with a grin, grabbing one of the mugs.  She brought it to her lips. “This is fer the Egarty ancestors.  Grant me strength.” She murmured before beginning to gulp it down.  With each glug, her body piled on visible pounds of sheer muscles.  Her arms grew over an inch in circumference every time, and she was gaining height too.

Erin chugged the entire brew in one go before slamming it down.  She was now a mountain of a person, towering over each and every person in the room and containing a far wider and denser frame than any of them could ever dream of.  Her clothing barely hung onto her frame, acting more like a skimpy athletics outfit.  A rigid, bulging set of abdominals covered her midsection like armor; each individual ab was like the top of a soda can in circumference.  Her eyes practically glowed in the dim barroom, and her red was blazing red, reaching her waist – which had meant it grown considerably due to her added height.

“Holy shit ma’am.” The bartender sputtered.  “Aren’t you going to drink this one too!?  You’ll be unstoppable with it!”

Erin smirked. “I already AM unstoppable.  That brew’s fer me brother.  Th’ Egarty tradition is ta have one brew per stop.  No more, no less.  Can’t dishonor th’ ancestors.”  Her accent had grown even thicker with her latest growth spurt.  Erin’s voice was even more thrilling and domineering as well.

“Right, right.  Whatever you say miss.”

“Now, a deal’s a deal.” Erin said before turning her tremendously wide back to the barkeep.  She drew in a deep breath, and with a voice that filled the entire room bellowed “Alright lads, I’ll shag the first man who can take me down!  Come an’ get it!”  For a brief moment, the fighting ceased and every pair of eyes attentively stared at Erin.  Another moment passed, and the entire room was charging at her.

Fifteen minutes later, every single ruffian had been knocked out cold.  A couple of bones may have been broken, but far as Erin could tell, that was the extent of the injuries.  After completing her task, she took the second brew and headed outside.  As she emerged from bar her awaiting fans began cheering for her, and drooling over her latest set of improvements.  With a wide grin, she reached down and handed Edmund his beer, waiting for him to drink it on the spot before they took off to the final bar.

5.)  The final stop

Erin Egarty was literally carrying her four fans on her broad arms, two on each side.  Even with their combined weight, she barely felt challenged at all.  It took all of Eric’s effort to keep up with the long strides of Erin’s massive legs.

“I think I know what yer thinkin’ Eddy.” Erin said with a mischievious tone.

“Oh yeah?  What’s that sis?” Eric had to speak loudly to make sure that she could hear him; she stood a full head taller than him, and there was the general murmuring of her admiring fans to contend with.

“Each brew has given me a substantially larger upgrade than th’ last, and there’s still one more to go.”

Edmund remained silent.

“So, I think I know what yer thinkin’.” Erin added with a wink.

“And what’d that be sis?”

“What th’ effects of this final brew’ll be.”

Edmund gulped.  “What do you mean by that?”

“Just think about it Eddy.  I’m already THIS strong, and th’ next brew’ll have an even bigger impact than th’ last.  Just think about it Eddy.  Think about how strong, fast, durable and unstoppable yer little sister will be.”

“But.. Erin.. You’re already the strongest woman, nay, probably person alive!”

“Is there any doubt?  And with this final brew… well just imagine Eddy.  Just imagine.”

Imagine was exactly what Edmund did.  All he could think about was his sister becoming something of a living, breathing superhero.  She’d be able to effortlessly lift buses, scale up buildings with ease, and outrun cars.  She’d be able to do anything she wanted!

At long last they approached the final bar.

As for what happened next?  Just how big Erin became?  If she obtained any powers?  Or if anything happened at all?

Well readers – I’ll leave that to your imagination.
