Another week passed
.
Imogene stood nervously in the room that was
designed
to be used for artificial-semination. Bright lights shone above her, her surroundings sterile. There wasn't much in the ways of decor since the room had been repurposed to accommodate its
new
purpose, a single long exam table at its center, the walls lined with gray-steel countertops and wooden cabinets, a few anatomical posters here and there still present; besides that most of the actual medical equipment had been removed to storage, no longer needed now that a much less
scientific
experiment was to take place.
After
hours
more of salacious fun together - along with a shower for both of them and almost as much time spent
cleaning
- she and Bridget really had sat down the next day and talked about what needed to happen. The pair once more convened in the Overseer's office, much of her semen-ruined belongings replaced, almost zero evidence left of what had taken place in that very room. Bridget had taken a pregnancy test that very morning - the vault having
thousands
in stock - and confirmed that she was indeed pregnant. They'd been
successful
.
Their talk about how things would proceed was brief, but urgent. Bridget told Imogene that this wasn't something they could rush into: Imogene wasn't going to be allowed to impregnate all the women in Vault 62 as soon as possible for multiple reasons. One of which - and the most pressing matter at hand - was that a certain
measure
had to be taken before anything else. They had one more obstacle to overcome, and her name was 'Mei Nakamura' - the vault's Head of Security. Imogene was informed that
Mei
would need to be brought on board first!
Furthermore, it was explained to her that Ms. Nakamura wouldn't allow the lewd activities to occur under her watch - that was unless
she
experienced what Bridget had! And apparently the Overseer had already planned out how Imogene would do it. She would relay the information that the vault's Cryo Sperm Bank had failed due to some freak-incident with the power, but that Vault-Tec had secretly provided a back-up in the case that had happened.
Imogene
was the back-up! Yes, Bridget would tell her Head of Security that the company had purposefully included a futanari amongst the residents, and that she was to provide the semen needed for insemination
directly
in a worst case scenario - which is what they were currently facing.
Imogene had agreed to the ploy without complaint - Mei was on her list of people she wanted to bed
anyway
!
So there she was, waiting nervously in what had to be one of the most
frigid
areas of Vault 62, her suit only providing enough warmth to make the low-digit temperature tolerable. Imogene wasn't sure
how
her meeting with Mei would go but she'd do whatever she had to
seduce
the Asian woman if that's what it came down to. She'd made herself look presentable, her balls and cock tucked tightly out of sight, her secret still not revealed to anyone that wasn't Bridget; Imogene was also horny as
hell
, Overseer denying her any further lurid encounters despite her protests, Bridget claiming she didn't want to endanger her pregnancy - at least not until more testing was performed.
She tapped her foot anxiously. What was taking Mei so long? Bridget had given Imogene a place and a time to meet the Head of Security, and though she'd arrived early she'd still expected Mei to be there already! Leaning against one of the counters, Imogene kept her eyes locked on the door, so stressed out she had to remind herself to actually
breathe
; her eyes did flick to the clock across from her occasionally, counting down the seconds until Ms. Nakamura was due to arrive - she wasn't late yet but she would be if she didn't enter soon!
The door opened.
Imogene immediately jolted into an upright-position as the lead guard marched into the room, Mei quietly closing the door behind her once she stepped in. She looked exactly how she
always
did, her sharp features stiff, her hair short and feathered, her awesomely
fit
figure tightly wrapped in her jumpsuit; Imogene also noticed that Mei had her pistol holstered on her suit's belt, along with a walkie-talkie and her keycard. Mei didn't say a word as she entered, walking straight up to Imogene, her arms folded over her small chest.
Silence permeated the room. Neither Mei nor Imogene spoke, staring each other down, burning holes into each other. Mei gave the futa a once over, focusing on her crotch for a long moment, her eyes narrowing; Imogene tried not to let the uncomfortable aura surrounding the woman get to her, standing strong, her expression as neutral as Mei's. After several terse minutes the Head of Security took a step back, uncrossed her arms, and shook her head, sighing. Had she made some kind of decision?
"So Dr. Walsh wasn't lying to me," Mei said in her deep voice, meeting Imogene's eyes again, "you really were sent by Vault-Tec in case the Cryo Sperm Vault failed. You are a futanari? Is that right, Ms. Smith?"
Imogene nodded.
"Yes to both, though my name isn't 'Jane Smith' - that was just an alias. My name is Imogene. I was hired by Vault-Tec to ensure the experiment of Vault 62 proceeded as planned if anything were to go, erm,
awry
with the Cryo Sperm Bank - secretly, of course. You know how the company is."
She hoped her explanation sounded official, and when Mei nodded in return, she knew she hadn't blown her cover.
"I do. And so I am to be impregnated now? It seems odd to have the Head of Security be one of the first to undergo such a thing - it might compromise the safety of the vault."
"I... I understand your
hesitancy
at being chosen to undergo insemination so soon," Imogene started, picking her words carefully, "but it was in Vault-Tec's plans from the beginning, the idea proposed by Dr. Walsh herself. She wants to set a good example for the residents and staff, and hopes that having herself and you, the Head of Security, be some of the first to be impregnated will help ensure that."
"I see."
That was all Mei Nakamura responded with, causing Imogene to gulp.
"Then we might as well get this over with. The sooner it's done the better. I'll start stripping now."
Imogene was caught by surprise at just how
blunt
Mei's statement was. Her eyes widened as the fit woman reached behind her neck to begin unzipping her vault-suit, wondering if she should do the same. Mei didn't bother to turn away from Imogene, nor did she show any signs of being
embarrassed
by her actions, her features as cool and calm as ever as she bared herself to the futanari. Imogene tried not to openly
ogle
Mei, but it was difficult not to considering how
curious
and excited she was to see the Head of Security naked.
Mei's complexion was even
paler
than her own or Bridget's, probably in no-small part due to her heritage and the fact that no one in the vault had seen the Sun in nearly a month. Her shoulders were broad and strong. Her chest was small, her breasts less than a handful each, capped with even tinier brown nipples and matching areola - though Imogene licked her lips at the sight of them regardless! Her arms were muscular, Mei's biceps bulging with sinewy-brawn, light-blue veins snaking across them, visible beneath her ethereal skin-tone. She pulled her jumpsuit lower.
Her stomach was flat and
chiseled
, owing to a set of defined abs, Mei possessing a six-pack that bulged out with every breath she took. Imogene discovered that her hips were surprisingly
wide
, apparently having not noticed their jutting when she watched her walk around the vault. She was further surprised by how neat and
trim
Mei's groin hair was, her midnight-black pubes fashioned into a thin strip that rose to the bottom of her hard midsection. Thick, muscular thighs framed her crotch, and her pussy must have been utterly
miniscule
considering that Imogene couldn't really make out its presence between the Head of Security's legs.
When Mei finished undressing, she bent down and scooped up her jumpsuit, folding it and pulling something from its belt-loop.
"Here," Mei held out that 'something' to Imogene, waiting until the futa had taken it before she set her vault-suit down on the counter, "you can use this."
Imogene turned the object over in her hand, studying it, not understanding why she'd been given a bottle of
lube
.
"Lube?" Imogene questioned, glancing up at Mei, "Why do I need this? I figured we would just do some foreplay first and the-"
Mei shook her head.
"No. No foreplay. I want this to be over with as soon as possible - I am not here for
fun
. The lubrication should be enough."
She turned away from the futanari to face the exam table, bending over it and grabbing onto its edges, further presenting herself to Imogene by spreading her legs.
"You may proceed when you're ready."
Imogene's face went red, but it wasn't from arousal, it was from
anger
- who was Mei to treat her like this!?
"Um, but what about
me
? I'm not, erm,
erect
yet, and I can't do this unless I am!"
"That is of no concern to me. Do whatever you need to, just hurry up!
Glaring
at Mei, Imogene understood that there would be no reasoning with her. Setting the bottle of lube down, she stripped down, kicking her jumpsuit to the side. Her utterly
flaccid
cock and balls drooped down against her legs, shriveling from the coldness of the air; Imogene immediately grabbed her member and stroked it, warming it up, forcing
life
into her snoozing snake. She hadn't expected to have to
jerk herself off
! Things were not going as planned, and Imogene wasn't sure how to proceed, knowing that it would take her quite a while to get fully hard.
She switched her focus to Mei. Now that she could observe the woman's slit unimpeded, Imogene could see that it was indeed
incredibly
tiny! It might've been the smallest she'd ever laid eyes on, barely visible on Mei's groin, its shape nothing more than a thin line without any other discerning features present; Imogene
also
noticed the woman's backside for the first time, and was just as stunned by its size - because Mei had a fucking
fat
ass!
It must've been bigger than Bridget's! Two, white globes stared back at Imogene, so large they jutted out from the sides of Mei's waist
while
rolling up the small of her back. How the fuck did she not spot this before!? Mei's lower-cheeks were so enormous that Imogene was pretty sure they could've
swallowed
her entire head in their creamy cleavage, easily as fat as Bridget's tits; they also appeared to be incredibly
