Chapter 11 - Post-Procedural Debrief (Part 1 of 2)

Becca felt her heart skip a beat as the reverberation of her naked butt cheeks decayed over time, but the sensation of movement deep in her crack was just as consistent as it had been the moment it started...faint but consistent.  It felt somewhat like the orange peg and even somewhat like the tiny aspirin pill had felt between her cheeks, but while she forgot about the white capsule nearly moments later, she wondered if she could ever disregard the frantic frenzy of activity going on several inches beyond her fleshy globes. 

The other major difference was the temperature.  The boy felt a little bit cold when Dr. Walker was tracing him up the length of her right cheek.  And then when Dr. Walker was keeping her butt cheeks separated, when she let them collide…holy cow…her warm butt hugged him so so, so tight. Every square inch of his shivering tiny body said hello to her butt cheeks, and his skin was so cold!  He had warmed to the cozy temperature of her crack very quickly though, and now all that was left was the struggling; she guessed he was trying to get comfy since this was all so new for him.  Becca hoped it was okay for him in there.  She was glad that the procedure required her to add some of that lavender fragrance to her crack...at least it probably smelled nice for him in there.  And like Dr. Walker had said, her butt was plenty big enough and her butt cheeks more than soft enough to properly take care of him.  She hoped he hadn't had a change of heart. 

It had been about several minutes since the two women had performed the "installation" as they called it, and Becca was just swimming in her own mind, focusing on the movement deep in her crack, but her attention left the boy when she felt fingers wrapping around her one of her ankles and fabric at her bare feet.  Laura said, "I'm putting your feet through some training underwear. Don't worry, not THAT kind of training. I’m putting them on for you because they have to be on before you get up."

Laura guided Becca's bare feet through the leg holes of the pristine, white underwear, which looked a bit like boyshorts.  “This is a cute color.” Laura said, commenting on Becca’s blue toenail polish.  

“Oh, thank you.  It’s Essie Aruba Blue.” 

“I’ll look for it.” Laura said as she pulled the waistband up over Becca's ankles and up her calves, reaching her knees and stopping.  

"You can go ahead and take over from there, Becca." Laura said, releasing the waistband to settle just above the back of her knees. 

Becca reached down and began pulling the underwear up, lifting her wide hips up off the table/bed just high enough to hike up the undergarment, but it met some hefty resistance: the undersides of Becca's butt cheeks. 

"Oh....I think these are a few sizes too small for me."  Becca said, weakly trying once to rock them up over her glutes but failing. The band was now digging in under her glutes, which made them appear to overflow atop the underwear.  “They’re super tight. Can I stand up and try pulling them on.”

Laura looked from Becca to Dr. Walker, who smiled and nodded her head.  “Sure, Becca.  Just please note that your buttocks may naturally part in the process of bending your waist and legs.  Please make sure to tighten your glute muscles so as to keep the subject wedged firmly.

Becca pressed her palms into the bench as if she were doing a push up, and then sat back on her heels, making sure the entire time that her butt cheeks were clenched as tight as they could be.  She couldn’t help but notice both Dr. Walker and Laura looking intently down between her bare feet, expecting the tiny boy to have dropped out of her butt, although he was nowhere to be found.  Nowhere to be found because he was still in her butt.

As Becca grabbed the waistband of the panties, Dr. Walker continued,  "The undergarments may seem impossibly tight, but our very talented engineers have sized the undergarment based on the rear images you provided last year.”

“Isn’t this going to make my cheeks..like…less soft on him?  If they're like..squeezed super tight?” Becca asked.

“That’s a great question, Becca.  The answer is yes. You see, over the course of the subject's interaction with the female rear, one might argue that this moment will be the moment in which he is most resistant to his environment and most diligent in attempting to escape it.  Admittedly, it is somewhat counterproductive to our goal of acclimating the subject to your rear end slowly, but that goal is considerably low priority in comparison to the goal of keeping him safe within your rear."

Becca didn't like that she used that word. 

"Escape..?" she asked, still gripping the waistband and slowly starting to pull up.

Dr. Walker pushed past Becca's concern.  "It is extremely unlikely that the subject has even a concernable fraction of the strength required to actually part your buttocks enough to emerge from between them, but we do still have to follow protocol.  When worn, the undergarments will greatly compress your buttocks, creating an environment that the subject has no chance of leaving.  If he were to somehow emerge from your rear, which—again—considering how tight your buttocks will contain him--the full waist-to-upper-thigh coverage of the undergarment ensures the subject would at least remain pinned between your skin and the fabric of the underwear.” Dr. Walker said matter of factly.

“…Until you could reinsert him, of course."  Laura added.  

Becca looked over her shoulder at the underwear. She was not used to underwear that covered her entire butt, and the maroon color was very mature; it looked like something her mother would wear. These were cut far more conservative, both on the waistband height and the cheek coverage.

“They aren’t very cute.” Becca said, and then she squinted as if she’d just skinned her knee. “Sorry! I didn’t mean to say that out loud.”

Dr. Walker chuckled, “It’s quite alright, Becca.  That’s the kind of feedback we might normally have to pay for focus groups to gather for us.”

Dr. Walker took out her tape recorder, "Note to self: Consider printing training underwear in some more...feminine colors and youthful pattern designs." 

Becca lifted her hips once more and gave it another try, tugging up on the super tight underwear.  It was snagging the undersides of her large cheeks again, but she kept rocking the underwear, hitting against the waves of butt flesh until she established a rhythm.  Slowly yet surely, the underwear started reluctantly climbing the extreme slope of her cheeks.  The waves traveling through the jiggling flesh had less distance to reverberate as the waistband made grudgingly slow progress; more and more of her cakey cheeks were compressing and packing into the tiny panties as she bounced on her heels until all that was left exposed was the top several inches of her deep, dark crack.  She wiggled her hips side to side as she tugged, finally hiding the last remnant of the darkness between her butt cheeks.  'Good lord', she thought.

"How do they feel?  How is the subject responding?" Dr. Walker asked, clicking her tape recorder to accept Becca's answer. 

Becca shivered a little, "It's so tight on my butt it almost feels like I just have one big butt cheek, if that makes sense.  And he is...oh, he is definitely trying to move around, but at the same time I almost feel.....yeah…I almost feel him less..". 

Laura then chimes in, "That's because since your glutes are packed and condensed more tightly, they are much more dense, and the higher density means that your glutes have much less give, and the subject can try all he wants, but he isn't strong enough to move them...just like Dr. Walker said would happen." 

Dr. Walker smiled and nodded her head, "Alright Becca.  You did so well.  We will give you some privacy so you can get dressed. Please take your time and come see me in my office when you are ready. Do you think you can find your way there?"

“Yeah, I think so…” Becca said, a little uncertainty in her voice.  

“I know we walked around a bit and you might be turned around.  To get to my office, all you have to do is make a right out of this room and you’ll be standing right in front of Dr. Bexley’s office.  My office is right next door to hers. Can’t miss it!”

“Okay, thanks Dr. Walker.” Becca said, sounding more confident.

The door shut and Becca was alone...well...not truly alone.  Becca bent at the waist to pick up her jeans and noticed something interesting: her cheeks didn't budge; they didn’t part in the slightest.  Also, the leg holes were slightly digging into her upper thighs. They were definitely right, even if he somehow managed to fall out of her buttcrack, he’d be confined into one of the leg holes and held firmly in place until she could correct the situation, even if she was asleep and it meant he had to wait a few hours. 

Becca looked over her shoulder and down at her compressed rump.  Her cheeks protruded from her waist and her eyes danced over the subtle central curve of the tight undergarment as its tightness barely permitted the slight dip inward between her cheeks one would see in pants or underwear.  She lightly slapped her left cheek, the sound of impact dead, muted, and stiff; the flesh barely moved, but she could still feel the boy moving.  

What a cutie he was.  

She couldn't help but smirk a little. 

She pulled her jeans up and noticed it was a little easier, as her butt took up less outward volume due to the compression.  She stretched her white socks back over her bare feet and put her sneakers on.  She then put her bra and shirt back on, flipping her hair out of the collar and then looking in the full body mirror.  She put a hand on her hip and stood on her left tippy toe, accentuating the "shelf-ness", as Krystal would call it, of her booty.  She walked away from the mirror but turned her head to watch herself go.  It was insane that nobody would even know what was going on between her butt cheeks. 

She knew a girl in highschool who went to class with a buttplug in…or at least she said she did.  But that was just it...Becca never actually saw the buttplug and neither did any of her friends, and if the girl hadn't told one or two gossipy girls, she wouldn't have had any idea.  This wasn't any different…except for the fact that he was way smaller than a buttplug, way more adorable, and Jenny Henson wasn’t getting paid hundreds of dollars a week to keep something buried in her butt under her underwear and pants.  Becca left the installation room and followed the directions to Dr. Walker's office.  She passed Dr. Bexley’s office, recognizing the black-haired woman from earlier.  She was the one with the bob cut that had been feeling up that handsome man in the Reduction Therapy room earlier.  Her door was propped open and she was now wearing a headset at her computer, typing things on her keyboard.  Becca seemed to catch Dr. Bexley’s eye, and she smiled and waved politely.  

Just as Dr. Walker said, her office was right next to Dr. Bexley’s.  Becca knocked lightly on the door.  Immediately, the knob turned and Becca saw Lori and Dr. Walker talking, Dr. Walker’s hand on the doorknob. 

"Alright Lori, thank you so much for coming in.  You can return to the waiting room and I will let you know once I've finished up with him; I won’t keep him from you for too long."  Becca couldn’t help but stare when Lori’s massive ass bounced in her yoga pants as she enthusiastically shook Dr. Walker’s hand.  Lori recognized Becca from earlier.  

Lori didn’t say anything at first.  Instead, she just looked at Becca with raised eyebrows, silently asking a question.  What question that could have been was pretty quickly confirmed when the older woman’s eyes wandered down to Becca’s waist.  Becca looked over her shoulder at her large rump and then back at Lori with a cute smile.  A giant grin grew on Lori’s face and she patted Becca on the shoulder.

“Good for you, dear.”

Becca was practically hypnotized as Lori walked down the hallway toward the waiting room.  Watching that thing jiggle and shake, she didn't know whether to feel bad for Lori's subject or to consider him lucky.  Lori’s butt was WAAAY bigger than Becca’s and considering that Lori was a little overweight, her butt cheeks were probably super doughy and cushiony, too; probably way softer than Becca’s.  

That was a good thing for her boy, right?  

How confusing this all was!

"Sorry about that, Becca. Please, come on in and have a seat."  Becca shut the door behind her and approached the chair across from Dr. Walker's desk as Dr. Walker paged Laura regarding something about a psych profile for someone. 

"I hope you'll forgive the mess", Dr. Walker said, stepping around a cardboard filing box of papers.  "We’ve made some truly incredible progress in expanding our Participant and subject pools.  Our awareness campaigns have been very successful, and we've received a large influx of participation inquiries and applications…not to mention the batch of subjects who have recently become viable for assignment. A large part of my day involves looking through dozens and dozens of application forms, which are essentially just women photographing their backsides; the interns like to joke that it’s the dream job of every teenage boy."

Dr. Walker took a seat in her chair and folded her hands atop the only space on her desk that was not covered with papers; Becca remained standing, afraid to sit down with the boy in her butt.  When Dr. Walker saw her reluctance to sit, she smiled, "Becca...we've proven a proportional relationship between size reduction factor and resilience durability; your subject is currently 0.337% of his original size. I assure you…sitting down will not harm him." 

Becca had no reason to disbelieve Dr. Walker, but she still was hesitant.  Still, Becca was not stupid.  She acknowledged she would have to sit down eventually, and it wasn’t like the little boy was coming out of her butt anytime soon.  Becca slowly bent at the waist, her palms pressing into the arm rests as her large derriere slowly lowered to the seat.  She was focusing on the feeling of him in her crack, he seemed to have relaxed for a few moments but now that she was bending at the waist and lowering her rear, she thought she could feel him moving. Then, when her cheeks made slight contact with the cushion of the seat, it was unmistakable. Very slowly, trying to ignore his movements, she began trading the weight from her palms on the hard arm rests to her booty in the soft seat.  Just by slowly lifting her palms, she was increasing the burden of weight on her butt...and by extension, the boy trapped inside of it.  Finally, she felt a thin layer of air between her sweaty palms and the wood of the arm rests.  She folded her palms upon her upper thighs and wondered what it must be like for him in there...under all her weight.

Despite her concern, her strict concentration told her that the faint tickle in her crack was still there, and that meant he was okay.  She sighed in relief, relaxing into the seat.  "How can he breathe?  I mean...my butt is like…really squished up right now...I don't know if any air can get in there.."  Becca said, concerned.

Dr. Walker did not look worried.  "He will be fine in there, Becca.  We have been administering a series of shots to the subject for some time now, and they allow him to survive in areas and conditions that people like you or I might not be willing to do or even capable of doing at all.  Some of them are quite complicated, but some are simple.  One of these simple shots disrupts the subject's ability to regulate his own body temperature." 

Becca tilted her head.  "You mean...you made him cold-blooded?" 

Dr. Walker smiled, "Hmmm…there is a little more to it than that, but you can think of it that way, yes." 

Becca asked, "Why would you want to do that to him though?". 

Dr. Walker responded, "Well, we had to address the issue of reduced oxygen flow while between the buttocks of a woman.  Intuitively, the air flowing into a woman's rear is a fraction of the air content you or I might breathe out in the city or even here in this office.  Predictably enough, degradation in quality of breathable air is a function of buttock cleft depth.  Basically, the deeper our sensors go, the less quality the air is.  This is partially because of the air having to permeate between the buttocks and filter through whatever bottom wear and undergarments the woman may be wearing.  We discovered that, by removing the subject body's responsibility and burden of warming itself, we could reduce their oxygen consumption rates by as much as 65%.”

Becca's mind was being blown, occasionally wandering away from Dr. Walker's science and to the boy in her butt…and then away from him and back to Dr. Walker. “…but it sounds like it's hard enough for him to breathe in there as it is, how does it help to make it even harder for him to breathe?”

"We don’t make it harder for him to breathe; we make it so that he doesn’t have to breathe as much. Our studies indicate that the regulation of body temperature ranks as one of the most intensive bodily functions in humans, and therefore it requires large consumption of oxygen.  You are definitely right that permanently removing the subject's ability to regulate his own body temperature is not ideal.  However, at the loss of that function, he can now survive indefinitely within your rear...even in conditions of extremely low oxygen.  The only consequence is that some subjects are unable to sustain a normal body temperature without assistance.  Regardless of which category your subject falls into is not a problem for him, as your rear will keep him exceedingly warm and comfortable." 

Becca was relieved.  She had thought a few times about how silly it would be if she had to randomly remind herself to spread her butt cheeks so that the boy in there could breathe; she was happy to learn that she would not have to do that. 

"Interesting fact: the oxygen that will filter into your buttock cleft is actually not the only sustenance for the subject’s respiration.  This was determined early on in our experimentation, and it's one of the several reasons why we removed breast cleavage from the list of potential housing areas.  Although untreated subjects could theoretically survive just fine, we decided to develop another biological modification just for the sake of testing: the way he processes the air he breathes.  You, me, and every other person on the planet breathe oxygen, right?  Well...this is partially true, as what we breathe is partially oxygen."

She reached into her pocket and emptied its contents onto the table in front of her.  There were several quarters, dimes, and nickels.  She segregated the coins into piles in silence, and then when she was finished, she looked up at Becca, gesturing down to a pile. 

"Imagine this pile, equaling $1, is one breath." Three fingers came down on the center of three quarters, and Dr. Walker shifted them over to start a new pile.  She slid a nickel over with the quarters as well.  

"This is Nitrogen." she said, waving a hand over the quarters and nickel. 

She then engulfed two dimes with two fingertips, sliding them in the other direction.  "And this is Oxygen."  

She lifted a penny and traced her fingernail along the outer edge.  "And if I could shave off about half of this penny, it would make up all the other gasses that make up the air we breathe."  

Dr. Walker dropped the penny and it spun for a moment before flattening.  "The modifications we've made to the subject's biological processes effectively create within the subject a contingency plan for respiration requirements on the molecular level.  Treated subjects can now respirate on varying combinations of Nitrogen, Oxygen, Hydrogen, Carbon Dioxide, and Methane.”

Becca was not quite following.  "Well...what's the point?  If Oxygen can't get in my buttcrack then what makes it any easier for stuff like Methane to...." it was slowly dawning on Becca. As professional as Dr. Walker liked to keep things, Becca's cute button nose wrinkling up and her eyes squinting brought a smile to her face.  

"...Oh, yuck!"

"Looks as if someone remembers a bit about Chemistry."  Dr. Walker said with a smile. 

Becca was not as amused, "Dr. Walker...you're seriously telling me I have to.." she lowered her voice embarrassed and looked around, even though no one else was in the room.  She whispered, "you're telling me I have to…fart on him?" 

Dr. Walker said, "Well, you are correct about what the subject will primarily be breathing while in your rear: Nitrogen and Methane.  You are also correct about where it will be coming from:  you.  Your gas is balanced opposite of the air we breathe, being roughly 60% Nitrogen and 20% oxygen.  With this information, the biological modification was clear, and as I mentioned earlier, this was one of the main reasons to favor the woman’s rear end over somewhere else like her breast cleavage.  However, keep in mind that the subject is so very small, and he requires so very little to sustain life.  Throughout your day, a near constant but barely detectable supply of Nitrogen and Methane emits from your rear...and this will be enough for the subject given his diminutive size.  I only bring this up to you because when--not if--when you pass gas directly onto the subject, you may feel a bit of guilt, depending on the intensity of the event and what you consumed prior to the event.  You shouldn't feel guilt.  Not any, Becca.  Not only is this something that he must get used to, as it is a natural process of the rear he now resides in, it sustains his life! So do not feel bad.  If anything, he should be grateful..but we won't get ahead of ourselves.  We are certain that, given enough time, he will get used to it." 

"Does he know? Can he hear us right now?" Becca asked, her hands wandered down toward her hips. 

"Buttocks are incredibly effective at insulating things like speech, although heavy compression can result in a more sustained reverberation of audio.  Still, to put it simply, It's very unlikely." Dr. Walker said plainly, and Becca nodded her head accepting the answer.

"He can probably make out the bass in our voice, but it is likely all muffled beyond resolve." Dr. Walker leafed through some of the documents close to her. "Let's see....oh, here it is." Dr. Walker quickly scanned the document and then her eyes lifted and met Becca's.  "How were you planning on feeding?" Dr. Walker asked. 

Becca scratched her head, fingers disappearing in her gorgeous long hair. "Umm...well, I hadn’t really put a lot of thought into that, to be honest.  But I guess I would take him out and feed him bits of my food whenever I eat."  

Dr. Walker raised an eyebrow that looked disapproving.  

Becca appended, "…but…umm…but during times when he has to stay in my butt, like if I’m in public, I would...I dunno...if it can’t wait till later I would just wedge the pieces of food between my cheeks for him to find when nobody was looking?" Becca asked instead of answering. 

Dr. Walker replied, fingers gliding over the form. The silence was uncomfortable for Becca.  

"You could certainly remove him to feed him, and that is what a number of our Participants do for their subjects.  I can tell you based on Participant testimony that I would not rely on inserting the morsels between your buttocks for him to find.  Remember, he is so very small..just barely over one inch tall…and  unless you were to get lucky enough to press the morsel of food directly against the subject, there is a good chance he will have a hard time traversing the distance within your rear to locate it.  This would require you to plan feedings in advance.”

“That makes sense.” Becca said, nodding.

“However," Dr. Walker set the form on the desk, used two fingers to rotate it 180 degrees to face Becca, and slid it to her edge of the desk.  "Might I recommend an alternative?"
