Chapter 4 - Experimental Procedure

~~Mass Effect: Stress Release (Chapter Four: Experimental Procedure)


He wasn’t sure of the exact cause, but Steve Cortez could definitely tell that the mood was lightening on the Normandy.  Sure, Shepard still came down and worked obsessively on the Mako every few days, but she was walking with a spring in her step and he was pretty sure he’d actually heard her whistling from within the depths of the suspension casing.  Likewise, his colleagues had been talking about how LC Williams had suddenly lost that stick up her ass and wasn’t cruising around the ship looking for minor mistakes to yell about.
 If he didn’t know better, he would have sworn that both Shepard and Williams were finding creative uses for sticks and the various insertions thereof… but with whom?  Ashley had always struck him very much as a “traditional relationship” type of gal, and Shepard, well, Shepard was a little harder to pin down.  Still, the two of them in a relationship was hard to believe, and he had no idea what the two ladies had found to blow off steam.  All he knew was that the work environment aboard the ship was much more relaxed these days, and Steve was content with that.
 
 Lying on the bed after one of their lovemaking sessions, Shepard could only thank the stars above her that the cleaning system in her ship was so efficient.  She could barely even smell a hint of sexual fluids after it was done, which was a plus considering she often had visitors in her room for reasons other than conjugal.

  Looking down at her flaccid penis, Shepard had to admit that her captors had done a good job on it.  Despite its impressive bulk, there was something feminine in its smooth skin while soft, and how her potent testicles hung in a hairless, smooth (yet stretchy) sack.  It was certainly more attractive than the baseline male package, in Shepard’s eyes.  Lying on the bed mostly soft it measured 8 inches long, and seeing it lying there like relaxing python gave Shepard a small thrill of pride.

  Shepard certainly wasn’t the only one admiring her cock.  Ashley, having recovered from her latest reaming at Shepard’s hands, was eyeing it wistfully.  Rubbing her clit as if cooling down from their session, Ashley bit her lip as she fixated upon the sleeping beast.

  Shepard chuckled.  “You want that?”

  “Yes!” purred Ashley, who then caught herself.  “Well, yes, I’m good for another round, but what I was thinking was that I’d like to have one.  A cock, I mean.  Literally.”  For good measure Ashley rubbed herself a little more vigorously and shuddered in a small aftershock at the thought.

  Shepard’s eyebrows raised (and her penis did as well) at her LC’s admission.  “Ashley, I really don’t think we should do anything with the Procedure.  Just you knowing about it bad enough.”


  “Cut the crap, Shepard.  In for a penny, in for a pound.  Plus, don’t tell me you haven’t been wishing you could be on the receiving end of one of these bad girls for a change.”  Ashley reached down and gave the slowly swelling tube a squeeze.  “I bet you wish you could feel what I feel when you drive me to an eye-rolling orgasm every other night.”

  “I could just find a good man for that,” hedged Shepard, but Ashley could tell that her CO was taking the bait.  Her cock had swollen to full mast as she spoke and was drooling a steady stream of precum.

  “Here, I’ll deal with that while you consider my proposal, okay Skipper?”  Climbing on top of Shepard, Ashley eased herself down cowgirl style onto the revived 14-incher.  “I’m sure I can bring you around…”

 
 “We should have gone to Mordin.”

  “I know, I know, but secrecy!  Containment!”

  Ashley sighed.  “Mordin has one thing we lack: expertise.  Even EDI can only do so much.  Besides, containment is kind of a moot point now, isn’t it?”

  Shepard looked around the lab.  Two weeks of hard work and they had only screwed it up.  Their reworking of the Procedure had yielded a liquid agent capable of altering a person’s body, but somehow they had missed the crucial detail that the agent was volatile.  Ashley had forgotten to properly seal a capsule of the agent, and the two had returned the next morning to find that it had volatilized and gotten into the life-support systems.

  “EDI, how did life support miss this?  Surely it would have registered as a contaminant?”

  EDI’s voice came over the comm: “Shepard, I believe the contaminant scrubbers missed it because it is so tied in to Synthesis.  All species have had to update their biological systems on ships and in most facilities due to the minute changes wrought by Synthesis.  It seems the systems just thought it was another new Synthesis byproduct.  It was flagged, but not removed.”

  “So the entire ship is contaminated, then?  Is this going to start causing people to start mutating left and right?”

  “I do not believe so, Shepard.  Though your agent volatilized and escaped into the ship, I have detected no noticeable effects on the crew.  An analysis of the particles indicates that they would still need a specific, unique trigger to make any changes.  A trigger that would have to be manufactured.”

  Shepard heaved a sigh of relief.  “Good, because that’s the last thing we need.  People mutating all over the place sounds like the plot of a bad horror movie straight from the extranet.”

  Ashley was more visibly upset.  “All that work and I screwed it up!  I was this close to getting my own cock!  I mean, we can do it again –“


 “No, Ash.  This can’t happen again.  We could have injured or changed the entire crew.  We’ve got to stop.”  Shepard gave Ashley a consoling hug.  “We’ll just have to make do with what we have.”

  Ashley was not so easily mollified.  “Easy for you to say.  You got yours.  Look, I’m going to head down to the mess, I’m pretty hungry.”  She left the lab in a definite hurry.


 A half hour later…

  Shepard was jolted out of her nap by EDI actually physically tapping her on the shoulder.  “I’m sorry, Shepard, but you weren’t responding to hails so I had to come up here.”

  “Mwuh?  What is it, EDI?” Shaking off what little sleep she had sunk into, Shepard stood up from her desk and turned to EDI.

  “Lieutnant Commander Williams seems to be experiencing a strange attack.  You should come with me down to the mess area.”

  EDI fell into step just behind Shepard as she headed for the elevator.  Could this be related to the Procedure and the loss of the agent?

  Stepping out into the mess hall, Shepard saw a cluster of crewmembers around the table, muttering worriedly.  “Alright, everyone out!” shouted Shepard.  “I’ll handle this!”  As the crew dispersed and moved out of sight, Shepard saw Ashley sitting at the table.

  She was surrounded by empty dishes.

  “Lieutenant Commander Williams has consumed enough nutrients to sustain several soldiers twice her weight for several days,” EDI supplied.

  Ashley appeared to have a beach ball in her lap.  “I don’t know what happened, skipper, “She moaned wearily.  “I ate just like usual.  All of a sudden it wasn’t enough.  I just kept making more and more.  They tried to shoo me away and stop me but I shouted at them…  God, what is happening to me!?”

  Shepard moved closer to look at Ashley’s stomach.  “Ashley, how does your skin feel?  Obviously your stomach is stretched, but this isn’t humanly possible.”

  “Shepard, the most logical explanation is that Williams was indeed affected by the accident earlier.  My historical and cultural records indicate several instances, mostly fictional, where a nutrient buildup was the precursor to physical changes of some kind.  I suggest we get Williams into the infirmary and activate the privacy controls.”  EDI and Shepard lifted Ashley by the arms and helped her swollen form into the sick bay.  EDI activated the windows and they turned opaque, ensuring Ashley would have privacy.

  Just as they laid her down on a bed Ashley began moaning in distress, writhing about on the bed.

  “Shepard, Williams’ core temperature is rising slightly.  Nothing dangerous, but her body is evidently starting to use all the nutrients she consumed.  Additional scans of her body provide less than conclusive information.  We are going to have to ‘ride this one out.’”

  Ashley’s moans suddenly took a turn for the sexy as her pain seemed to turn to pleasure.  Her belly was slowly shrinking, though nothing else was happening.  Shepard, who had moved to console a distraught Ashley, was now somewhat awkwardly holding the LC’s hand as she became decidedly more erotic.  Shepard turned to look at EDI, who simply stared back.  Not being a medical AI, she had no bedside manner.  Shepard reluctantly turned back to her writhing subordinate.

  Suddenly, Ashley’s tight pants bulged forth at her crotch.  Slowly, the bulge began to grow, and meeting resistance, angled down into the left leg of her pants.

  “Well, Ashley, it looks like you got your wish after all!” Joked a dumbfounded Shepard, who was feeling a growth of her own making her pants tighter.  She had been asleep for her own transformation; just waking up with a cock was astonishing, but not particularly arousing.  This was different.  Seeing a moaning, squirming, glassy-eyed Ashley sprout a cock was pushing Shepard’s buttons in a way she had never thought possible.  This wasn’t just arousing; this was smoking hot!  Especially the way Ashley’s cock just kept growing…

  Wait, still growing?  It had to be a foot long by now!  Shepard reached down and grabbed the tubular bulge in Ashley’s pants.  Rock hard.  Ashley was growing her own wood, and it still wasn’t finished.

  EDI moved closer, evidently recording the process.  Shepard found herself hard as a bar of steel as she watched Ashley’s cock grow past the foot-long marker.  13, 14… “Fifteen, sixteen, seventeen... eighteen,” breathed Shepard as the swelling cock finally came to a halt.  “Holy shit, Ashley.”

  Ashley’s eyes refocused on Shepard.  “Wait, how long is it?  Eighteen?  God!  I’m a freak!”  Shepard amusedly noticed that while her words gave one impression, Ashley’s grinning face and the light in her eyes told the story – Ashley was thrilled.


  “Well, Williams, they do say every marine is a rifleman first, and now you’re outgunning Krogan, not to mention your commanding officer.”  Shepard chuckled.  “I have to say, I am a little jealous – Ashley, are you okay?”

  Ashley had lost focus again and was moaning like a woman in heat again.  All of a sudden she panted, “Pants!  Off!  Now!”  EDI and Shepard raced to undo her fatigues and pull them off with her underwear, exposing a foot and a half of throbbing, veiny grade-A prime beef.  As riveting as that sight was, Shepard soon had other things to think about as the massive rod swung up, finally able to reach full erection.  As it did so, it revealed the reason why Ashley had frantically asked them to get her pants off.

  The skin between Ashley’s vagina and newly minted cock was swelling.

  “Shepard, it appears that Lieutenant Commander Williams’ transformation is not over.  She is, in the words of some, ‘growing a pair.’”  EDI was examining Ashley’s growing scrotum from all angles, recording data for later analysis.

  “Thanks for the cultural touchstone, EDI,” remarked Shepard, as Williams’ new balls began to swell.  Golf balls.  Chicken eggs.  Tennis balls.  Shepard took some momentary pride that hers were bigger when full, but she soon realized that her cock was throbbing in her pants and needed relief.  There was no time for comparisons.  Ashley’s balls continued to engorge.  By now they were softball-sized, pushing Ashley’s legs apart as they grew.  As they reached the size of soccer balls, they slowed and stopped their growth.  Gazing at the magnificent example of masculine equipment in front of her, Shepard found her breathing shallow and her cock pulsing of its own accord.  Her pants were beginning to bulge out as her cumtanks inflated with seed, but Shepard was too fixated on the enormous globular sacks of virility in front of her to address the problem.

  How much cum could her LC produce?  Surely it would dwarf her own ejaculations; Ashley’s balls were at least fifty percent more voluminous than her own, even at the largest inflation she’d ever achieved.  Shepard’s breathing sped up as her imagination went into overdrive.  Her hands were still holding Ashley’s legs.


  Ashley’s cock bucked, and began spewing hugely thick wads of cum feet into the air, raining back down on her and splattering EDI and Shepard.  This triggered a third change in Ashley: her nicely-shaped C-cup breasts began to expand.

  EDI looked at Shepard worriedly.  “Shepard, if this continues Ashley may be in danger.  I suggest we… Shepard?  Are you listening?”

  At the revelation of Ashley’s full transformation, Shepard’s eyes glassed over and she promptly flooded her shirt with a torrent of cum.  As her cock had grown up between her breasts rather than down a pant leg, the entire front of her shirt was inundated with thick, goopy cum.  The pressure of her hands-free ejaculation actually shot some cum up out of the neck of her shirt to coat her neck and chin.  As the cum oozed out of her shirt, Shepard’s hands flew to her nipples, which she tweaked in ecstasy.

  Ashley was in little better condition.  Her cock was continuing it’s automatic fire, spraying the three of them with an off-white coating.  Her balls, unlike Shepard’s, were not shrinking as they pumped their payload into the air.  Her breasts were just finishing their inflation, stopping at a meaty HH cup.  They hung firmly on Ashley’s chest; sagging slightly under their own weight so as to look realistic, but still very firm and attractive.  It was a good thing Ashley had been wearing her workout shirt; the stretchy material was clearly taxed by the newly buxom woman but it held.

  Faced with two squealing, ejaculating women, EDI was rapt with attention.  Necessary observation was simple; that took up a tiny fraction of her processing power.  No, what EDI was spending an inordinate amount of attention on was the evident pleasure on the two women’s faces as they rode out their enhanced orgasms.  She tapped into the medical bay cameras for alternative angle close-ups of their faces, recording as much detail as she could; mouths hanging open, tongues hanging out, eyes rolled back or staring into nothingness, skin slick with sweat or coated with sexual fluids.  The sounds, too, were recorded; the throaty moans, the bestial grunts and squeals of mammals in orgasm.  The splatter of seminal fluid and the squelching sound of thick ejaculate sloshing about in a shirt and between fingers.  And of course, the sexual organs of the women themselves.

  One of the perks of being fully sentient and now “alive” was that EDI had interests.  Since Synthesis, EDI’s AI nature allowed her copious amounts of “free time” to pursue those interests, dabbling in science, literature, political thought, all from different societies across the galaxy.  And ever since Shepard had returned from her abduction, EDI had found a new interest.

  All those teachers in educational vids had been right, EDI mused.  It was one thing to learn about a subject through video, or reading about it, or hearing someone else describe it.

  It was entirely another thing altogether to see it for yourself first-hand.
