Hi, and welcome to my undercover sideblog for Und3rt4le-D3lt4rune niche f3tish content. (I’m mainly interested in Sp4mt0n and T3nna, but enjoy content and doing things with M3ttat0n, J3vil, and S3am as well). I’ve been lurking for sometime, and I do write f4nf1c under the A03 anonymous collection.
It drives me crazy to do it, but I will be using a lot of slashes and periods and numbers to keep things out of searches here.
Anyone coming across this who is under 18, please DNI and navigate back. This is for both your protection and mine, and I cannot stress that enough. We’re not dancing around the nature of what I’ll be posting about here, even if my own depictions may be tamer than most. Because 1. I’ll be interacting with blogs where that might not be the case, and 2. I had a past experience years ago in an art community where tamer f3tish-adjacent content was normalized to be safe and simply childish humor. It leveled up and ended in a traumatic experience. I will not support the mindset that allowed that to happen to me, so even if you think you’re close enough in age because you’re within a year or two of getting there, please understand that this is more than a “because I said so”, and just wait. I do not want anyone going through what I did. (Peace and love to you, but please stay away until you’re old enough!)
The rest of my DNI is fairly simple. This is a safe space, and a shame-free space, so if you’re going to be a jerk, or if you hold beliefs that are hostile, stay away. If you simply don’t like or feel comfortable with the subject matter on this blog, please navigate back quietly. Hateful comments are only a waste of time for everyone.
I am strictly against p3doph1lia/und3r4ge, 1nc3st, n0n-c0n, and z00ph1lia/b3sti4lity. Please do not interact with this blog if you post content involving these things on yours, or if you post any sort of N$FW content with characters depicted as minors. I have other squicks that I can scroll past without much bother, but these I cannot, and I do not wish to be associated with them.
My main interests I have set aside for this blog specifically are omorashi and dacryphilia, with a twist. Some forms of sickness as well, but in my own work, usually minimal description or implied and focused on comfort.
I do not expect to be very active here for now, but I do want someplace where I’m not under a completely anonymous function, so I’m not quite so cloak-and-dagger, but there’s a chance this blog could disappear if I am found by the wrong people.
I will be following from my main alternative blog, eventually. Anyone here is welcome to view it, but let’s keep quiet about it, okay? Please and thank you?
And a little more info about my interests and me under the cut:
Assuming you want/need more information, that is. The meme may identify me from A03 to some as the “Relief In Recovery” series author, and that has driven me to make this account to have someplace I can be reached. My N$FW stories and those linked to that universe will remain anonymous though, so that even if I am found here, I can delete this account, and there is nowhere else for those stories to be traced to, and thus, they can stay up. I do write gen, SFW fic there under a real screen name, too.
Also, I usually comment as a guest on stories of the sort on A03, despite having an account for the same purpose of not being able to be traced there. I don’t want to be weird by popping up more often without having some sort of digital face, so I’ve made one of its own entity. Hope y’all understand, because I just want to give the awesome artists and writers I’ve enjoyed the works of some love.
Yeah, my Charlie-Browning about why it’s so important that min0rs DNI? That’s why I’m hidden. I have a stalker/past abus3r than has popped up every now and then, and I have been evading them for almost ten years now. I’m not going to trauma dump on the specifics. If you end up following me here, and you think you know me from somewhere else, please keep quiet about it so this blog can stay alive.
So yeah. Just here to give some love first and foremost, and maybe take back some freedom by getting back into things I did enjoy that I haven’t felt safe to interact with for a long time. I may share some stuff relevant to my writing so I’m not just rambling headcanons in anonymous asks every so often, or having ridiculously long author notes. I do draw, but I probably won’t do much of that due to my past. I won’t take requests unless I build up a lot of trust, which won’t be for awhile, though I may draw something related to a headcanon if I feel inspired and I want to. (I don’t foresee it being a problem, but please respect my boundaries with that. 🙏 I feel like it would be too specific to explain why on this.) I did my profile pic here, but it’s not in my typical art style as part of remaining hidden.
My way I’m interested in omo is really more hurt/comfort oriented, and less spicy than most, but I do enjoy works by those who use that take. I kind of got into it by route of being paruretic, hence the “stagefright” in my screen name, and probably another reason why I’m drawn to omo in a recovery setting. It’s really the hurt/comfort that draws me in. And the dacryphilia. (I never got scared away from dacryphilia). But, after an extensive training background in physiology, I’m very drawn to the chain reaction of physical sensations, too, and that plays into my writing and interpretations a lot.
DMs and asks are welcome for inquiring minds about stuff on A03 and headcanons. I am open to discussion about variations in headcanons, and if I share any asks or thoughts, I ask that all be regarded with respect, even if not everyone may agree with each interpretation of the characters. Let’s all be kind and supportive here, okay?
Omorashi fa.na.rt based on my d3.lt.4r.uin.ed Relief In Recovery AU
The Paruretic and the Polydipsiac. aka bathroom problem moral support frenemies, stuck waiting in a bathroom line somewhere in c4stle t0wn under the cut
If the last picture I did tried my patience, this picture was reborn out of a fiasco that tried all my motivation. But my journey posting omo content online began with these opposite sides of the same coin in a recovery arc, so of course I had to draw them together. And I know he’s not as popular and he’s a pain in the butt, but I love J3vil and he deserves love, too.
Anywhere these two are, lines are bad news. They make it harder for Sp4mton with his shy bladder because he knows he’s holding the line up when he can’t get started peeing. He also has more time while waiting to worry about what might happen if he can’t go, so he’s even more nervous. J3vil has a lot of anxiety in recovery that gives him compulsive thirst. He’s still unstable enough to get too distracted to go before he’s desperate, and it sneaks up fast on him with all the fluids he drinks. And the anticipation of getting near a bathroom makes the urges stronger, so standing outside in line can be his undoing.
This doesn’t really correspond to any particular scene in my existing stories or any upcoming ones I have outlined, though it’s implied in my first AU story as something that happens a lot. J3vil is trying not to lose control before he gets to the toilet, and Sp4mton is trying not to let his nerves spiral when he already tried going earlier and couldn’t relax. In their c4stle t0wn AU recovery arcs, they still have petty arguments and are too stubborn to admit they’ve become friends, but both know how hard it is to deal with bladder problems, and they look out for each other around bathrooms away from home. Both try to distract each other whenever they’re in a line, J3vil will offer to guard the door for Sp4mton if he’s struggling to let go, and if Sp4mton has a failed attempt and needs to try again, it helps J3vil remember to go before he’s at a crisis point. Sp4mton isn’t as self conscious about needing to try again so soon when J3vil is also making frequent trips, so it works out. They’ll take digs and jokes at each other over many other things, but mean spirited rivalry stuff is off limits with close calls and accidents.
They’re not too far gone in this drawing. J3vil isn’t using both hands yet, but having to hold himself does mean he might leak a little while he’s getting undressed yes, he takes his gloves off but doing that in line would make his anticipation urges worse. Sp4mton isn’t glitching out yet, but the way he’s clasping his hands at his chest is something I headcanon as one of his tells of desperation. Drawing this became an unplanned characterization study. J3vil is blatant with his need, he doesn’t care what anyone thinks, and he’s not ashamed to openly hold himself if that’s what he has to do. Sp4mton is a lot more subtle until his glitches take over, he’s shy about how he’s perceived, and he will do anything to resist holding himself and even show that he’s not. But anyone who knows him well knows that if he has his hands like this, it’s only a matter of time before he’s clutching down lower.
About the fiasco note. I sketched this on the same day I sketched my M3ttat0n drawing weeks ago, but seasonal humidity makes some pencil colors lay down with a gummy consistency and others more dry and brittle. Color blending was a bear especially on J3vil’s face, and I fought it so hard the paper surface started disintegrating. And then it was impossible to blend colors at all. And it was probably okay, but I just wasn’t happy with it being all patchy and smudged when I knew I could make it look better. So after a break, I started over entirely and redid the whole drawing from scratch over the last couple of days. And while I did like the details on Sp4mton’s face just a tiny bit better on the original, I’m really glad I did and feel like I had major improvements overall on the second try. I share that because it did feel weirdly symbolic for a drawing of two characters in a redemption AU to have a redemption of its own. But even when the picture is entirely colored, it’s always okay and never too late to start over and try again. Which is an experience I share without shame for anyone else who tends to be their own worst critic and also needs that reminder from time to time.
hii, just wanted to know... have you posted any of your other works in here (if you have any others, ofc)? i've read the ones from your ao3 and i really liked the way you depicted the sillies... keep up the great work 💯💯 📧📺💘
Oh, hi! As far as full length stories go I only have those over on A03 and that’s probably the only place I feel comfortable having them. I do occasionally make some art here when I have time, and some of it is related, and I have headcanon breakdowns here, but that’s about it. The only other stuff I have is one unrelated SFW de.lt.4r.une work on my actual A03 account name, which I’d be willing to share by DM, for the purpose of keeping that separate from my anon works.
As far as works go, I am working on a T3nna centric story that I’ll hopefully finish soon with as complicated as some parts got I’m trying to rein it in. And I have been working on some art that I should have up in the next day or so.
I appreciate it though, and I’m glad to know you enjoyed what I’ve gotten through so far. I’ve been a little sluggish creatively after a little rough patch a few weeks ago and just being busy with life, but logging in to kind notes does lift me up. 💜
what is it about the brain rot of this kink that any time you have a new favorite character, you’re absolutely possessed to know if anyone has made them piss themselves or not
After some organization, the next deltaruined omorashi math series is here, and Sp4mton won the poll for next up, so he’ll be the focus of this and the next post. Those five who voted for M3ttat0n, don’t worry, because he’ll still be next to be featured after Sp4mton’s installments and I am very excited to get to him!
But, let’s get into it. This will focus on calculating capacity, and the basic differences between BS Sp4m and Pu.pp.3t Sp4m in how desperation builds up and manifests itself. Under a cut because of length, as usual.
I am working on putting together a mast/erp/ost for these as well to make it easier to reference ideas that carry over.
We’re jumping into it with Sp4mton’s bladder capacity. Seems appropriate to start with when this all started from a question on deltaruined-confessions on how much T3nna’s bladder holds, right? We know he’s small. There’s no official canon height, but comparisons of pixels have put him in a range of a max height of 5’4” and a minimum 4’9”, so with the idea he shrank with the pu.pp.3t transformation, for these purposes, I’m considering BS to be around 5’4” or maybe a tiny bit shorter, and pu.pp.3t as 4’9”. There’s no rule that he can’t be shorter than that, as many headcanons do go for that. His bladder sizing would need scaling down from what I’ll have here if he’s depicted as a 3 foot thing or something like that. I’ll show you how at the end! Why not?
With heights based on pixel scale, he’s actually still in a range to use the average human bladder sizes that were scaled up to calculate T3nna’s bladder capacity. But, it’s also a popular headcanon for him to have a small bladder, so he might fall on the lower range of those average human capacities, where as we pushed upper end for T3nna before scaling up for the fun of him having a big bladder.
To recap the textbook guidelines I used for T3nna, quoting a physiology textbook I had for school well over a decade ago now, the average human bladder can comfortably hold about a pint of fluid, which falls between 400 and 500 milliliters. The 500 mLs is a favorable reference as the half-liter, as we talked about in past installment why the me.tr.ic measure is favorable for figuring out how heavy the bladder is. The first feeling of noticeable urgency usually comes in around 250 mLs or 8 oz again not an exact match but close, which is the stage of kind of needing to go, but it’s easy to ignore and not so bothersome. The bladder is dangerously swollen at 1 liter, or slightly over 1 quart/32 ounces, though some with larger than average bladders may hold more. This is the absolute capacity stage where an accident is imminent if there is nothing preventing being able to empty the bladder, as continuing to hold at this capacity can do a certain amount of damage to the bladder and the body will try to protect itself from this. It becomes painful and difficult to hold long before this, with the pain threshold usually being somewhere between 600 to 800 mLs depending on how used to holding it someone is.
Putting this up against Sp4mton for basic level before getting into BS vs pu.pp.3t details, we know he won’t be in that population that can hold over a liter of pee if he has a small bladder. He would have to fight really hard to hold just a liter, or be unconscious to get there, if he even can. So maybe his absolute capacity where his bladder gives up is around 900 mLs. If he’s holding more than this, something is preventing him from being able to go, and it is not a voluntary hold. If the mild desperation threshold on average is around 500 mLs or slightly less, where the urge becomes persistent and starts to become uncomfortable, maybe he hits this more around 400 mLs. It’s not painful yet, but it’s already bad enough that he can’t ignore it and might be getting fidgety and irritable. And he probably starts feeling the slightest urge starting around 200 mLs instead of 250. Pain threshold has some caveats to it, so we’ll hold off pun intended on that for now.
And now comes the fun of comparing. We’ll start with BS Sp4m, and there will be additional caveats for headcanons that I’ll attempt to accommodate for where they may adjust how different things are for pu.pp.3t Sp4m. I like to imagine him wanting to appear tough and not wanting to be seen desperate when he’s sober and at work, so he pees every chance he gets. Sometimes phone calls get him stuck holding it longer than he’d like to, but he’ll use excusing himself to go check on phone calls as a way to sneak off in T/V W0rld without having to tell anyone that he’s going to the bathroom, because he’ll just hit it on his way to or from the phone. I also headcanon that he’s weird about not wanting to tell anyone when he has to pee, but he has no problems using the bathroom once he gets there. This frequent peeing has implications to his desperation thresholds.
He starts feeling the urge at 200 mLs. That’s not even a full 8 ounce cup before he might sneak off on a slow day. He might start feeling a bit desperate around 400 mLs. So he’s already pushing toward feeling desperate if he drinks a single standard 12 ounce coffee. He couldn’t drink a standard pint sized single use water bottle without being considerably past this. He’s sneaking off to use the bathroom a lot. He’ll be in a terrible mood if he gets caught on the phone or in traffic too long after drinking his coffee, because that’s past the point he’d want to be holding if he had a bathroom available and the chance to use it. Because he pees preventatively a lot and his bladder doesn’t have much tolerance or conditioning to stretching past his desperation threshold, his pain threshold is going to be on the low end, probably closer to 600 mLs. Considering he starts feeling desperate at 400 mLs, it only takes about a cup past his level of starting to feel desperate to get him to the point of achingly full. Which means once he starts feeling the urge too strong to ignore, it’s going to escalate fast for him.
Let’s think about that in the context of common headcanons where BS Sp4mton loosens up after work and is pounding down drinks at the bar. If it’s small mixed cocktails, he’d probably get a few down before desperation starts, which fits the characterization I see with that. Hypothetically, if he drank a couple of beers, he’d already be full enough to be in pain just for that. But if a mixed drink or cocktail like he’d probably be drinking is somewhere around 150 to 200 mLs by the time everything is added in assuming he’s not doing unadulterated shots, he’d only have to drink about 4 of them on the low end to hit 600 mLs and start feeling it ache and get really desperate. To hit 900 mLs, if that’s about his absolute limit of what he can voluntarily hold before he’s leaking all over himself and eventually wetting, that’s 6 mixed drinks at 150 mLs, or not even 5 at 200 mLs. The headcanon of him drinking a lot and getting super desperate in BS era checks out very well in math. Not that it took math to know, but it further supports how he might easily push past his limit if he were to get inebriated and lose better judgement of where to stop himself. It’s also worth noting for headcanons with alcohol consumption that it does dull urgency signals at first, so a character might not realize initially just how badly they have to go until they move a certain way, so with his small bladder, Sp4mton might not notice until he actually hits his pain threshold if the fluids don’t catch up to him until he’s already buzzed.
The main difference for anyone who headcanons him holding until he’s really full all the time if he’s not as shy about being seen desperate or having his needs known is that he might get more full, somewhere around 700 or 800 mLs before he’s feeling the ache from distending. In that case, he would be able to cope with rising desperation longer, but once he feels painful, he really doesn’t have much time left before he catches up to his absolute limit. Compare that to feeling the ache earlier and realizing his desperation earlier on, but having more time to try to make a decision on what to do about it, and being uncomfortable enough earlier on to make this a priority for him.
And then we move on to Pu.pp.3t Sp4m. His bladder size on its own isn’t likely to be much different, but the anatomy around it and his habits and m3ntal state have changed a lot, and that will influence how it behaves. It’s one popular headcanon that he develops incontinence problems, in which case his capacity could go to either extreme, with either flaccid bladder incontinence with constant dribbling and emptying, or spastic where he would retain a lot and only leak overflow. I have a headcanon that he does have control and he can hold his bladder, but he becomes extremely paruretic or pee-shy, and instead has a hard time being able to relax enough to let go, and over time, this has set him up for retention problems and bladder infections. The details and effects of those will be in their own post, but they’re worth mentioning as an overview.
Assuming a situation where Pu.pp.3t Sp4m does maintain control over his bladder, unlike BS, he might be apt to hold longer with his lifestyle on the streets. Especially if his secrecy around using the bathroom carries over. If he abandoned this and just went wherever outside whenever he felt like it, that might be the gateway to the incontinence or really weak and leaky bladder headcanon path by training his way out of holding at all. But, if he wants to wait until he has access to a bathroom he can sneak into, or until it’s less busy around the trash zone alley to sneak into position somewhere discreet, he would hold more. Even if he has access to a bathroom someplace he’s allowed to use, as I have in my stories because I didn’t have it in me to be but so cruel to him, having to go to there from his dumpster every time might not be very convenient. It’s not terribly far away, but it’s a bit of a walk, and he just went a couple of hours ago, and maybe he can wait just a little longer before he makes another trip. If it’s in a business that isn’t open around the clock, and it’s close enough to closing time, he might strategically hold off just so he can go as close to that closing time as possible to increase the odds that he can hold it until places are open again for the next day and he won’t have to figure out something in the middle of the night. If he’s having to sneak a pee outside, he might have to wait awhile before it’s clear around him, because he might also have to be on guard about whoever might see him so he doesn’t get chased away from his survival means. His secrecy might be less about pride and more out of necessity.
So, this interpretation of pu.pp.3t Sp4m will have a holding stamina that BS does not. He will get used to holding, and there are some changes to help him along with that. Over time, his bladder would gain a limited tolerance to distention that he might not have had before. His pain threshold would increase, and he might get closer to that 800 mL amount before his desperation turns painful. He’s also probably not always as hydrated as he should be on the streets, so his bladder is filling up slower. Which, as discussed on a T3nna topic, actually allows the bladder to fill up more before urgency signals get as strong because stretching slower means less stretch receptors getting triggered at once. His bladder is still small, but he copes better with it being full. Up to a point. Once it becomes painfully full, it’s not any easier, and there still is a point at which he can’t hold it. There is also a downside in retention problems from the chronic fullness, which again will be in a follow up so this doesn’t get too long, or more than it already is.
Sp4mton’s body changes mean he now has an exoskeleton. He no longer has a pelvic bone close around his bladder, but he is more triangle shaped, so his body cavity is more narrow in that region. His legs are shorter, but his torso isn’t much different in size, so his bladder shouldn’t have gotten smaller. As the bladder fills, it normally expands upwards out of the pelvis and into the main abdominal compartment and this is true for any species with a bladder. Lack of a pelvis may mean less internal pressure with filling earlier on, so his early urges may be even less bothersome unless he has a bladder infection as another one of my headcanons goes, but the triangular body shape means his bladder would expand upward much faster. At first, when he is partially full and it can still be compressed, his other internal organs would push back to a point and there may be less connective tissue in his pu.pp.3t body to anchor and limit how much they can push down. But, as his bladder begins to firmly distend getting into that pain threshold window, if I also take my headcanon of him having a hard, thin plastic body shell, his body wall has a limited ability to bow outward and give him room to expand horizontally. This can still happen, but he has a tiny little bladder bulge! It probably wouldn’t show unless he hiked up his jacket or opened it. So, once his bladder has forced his body shell outward as much as the plastic allows, it has to keep pushing upward, and pressure against his body wall will allow his bladder pressure to be stronger than the rest of his guts resisting it, and it will push these upwards into his diaphragm.
So if pu.pp.3t Sp4m is so full he’s on the verge of wetting himself, somewhere around 900 mLs or just over that, he might also be short of breath from the compression against his lungs being able to expand. With however much he might force being able to breathe deeply, he might be getting his stomach compressed between his lungs and a very full bladder, and this might make him feel queasy, too. All of this assumes glitches haven’t already made him lose control, because increasing desperation will make him glitchy, and if he’s over his pain threshold, his glitches are going to be severe. Glitches may cause bladder spasms, so the bladder trying to contract when full, meaning his urgency kicks up even worse with every spasm from a glitch. Eventually, his holding muscles will fatigue, so he will start leaking through. If he’s having a paruretic lockup as in my AU, it may take longer for this to fatigue, and the more stressed he is, the longer it will take for it to fatigue. This may actually overstretch his bladder up to a liter in some extreme cases, which is something he could not do without being locked up if he tried. But the consequences of that are a whole different can of worms, so that’ll wait for next time!
Really quick, if you want to scale his bladder for different size headcanons, the formula for bladder scaling is first getting a factor by taking your height for him and dividing it by 5 which represents human height for simple math. So, if you see him as a 3 foot gremlin thing, 3/5 = 0.6. That’s the factor to then multiply against bladder capacity. So, if we said Sp4mton’s absolute bladder capacity is 900 mLs at human height scaling because his bladder is smaller than average, 900 mLs x 0.6 = 540 mLs. So, a 3 foot tall interpretation of Sp4m could only hold 540 mLs, or barely over half a liter. It’s the same formula if all began with when we recognized that T3nna at canonical full height is 3 x human height, and multiplying by three became the factor to scale up his bladder. 15/5 = 3, and if he has a larger than average bladder, 3 x 1.5 L = 4.5 L. And that’s basic bladder scaling math, not accounting for special conditions.
I’ve been a bit preoccupied for multiple reasons, but my goal is to have my next omo math and phy.sio.logy installment up tonight or tomorrow. Sp4mton won the poll from a couple weeks ago, as I expected he probably would, so it’ll be about him. He won with 13 votes if I calculate to remove my own, since I didn’t realize I’d have to vote too to see the results. The 5 voters for M3ttat0n though, you guys still win, because he’ll be next after Sp4mton, who will probably be about 2 or 3 posts to get through everything.
The tiniest side effect of one of my he.al.th pro.ble.ms is making me so pee brained this week. I’m ok just taking it out on making T3nna pee himself still.
As soon as I posted my poll on who’s next for deltaruined bladder analysis and omo math, I thought of one more thing for T3nna. It does connect to ideas that will be more pertinent going forward, regardless of what character I do next. This is about rapid desperation and fluid consumption over time, so there’s one more thing to hold over until the poll is done and I start on the next. This is also an opportunity to make a reminder that if you are interested in these and have a preference on who’s next to vote if you haven’t already!
We know T3nna loves his coffee. But, there’s just a little fun to be had in considering how fast he drinks that coffee. Because the same amount of fluid in the bladder can produce drastically different levels of desperation depending on how fast that fluid is consumed, which is one factor in how fast that fluid collects in the bladder.
I’ll do the physiology breakdown below, but let’s consider how T3nna’s mood might impact this. If it’s an average day and everything is going well and he’s calm, he might sip his coffee slowly over the course of an hour. A “cup” of coffee for T3nna is probably bigger for him than it is for us, unless he’s shrunken down, so let’s imagine if he’s got that 4.5 liter capacity from previous breakdowns, his coffee mug is 2 liters. That’s equivalent to a person drinking something like a 12 to 16 oz coffee. By the time it gets through him a couple of hours later, he’s going to want to pee and will be feeling some discomfort with holding, but unless he’s been drinking additional water at the same time with that coffee, he shouldn’t be struggling too much to hold it yet, and he has some time to see if he can find a good opportunity to go to a break. If he drank it slowly.
Now, let’s imagine T3nna is stressed out for whatever reason. The family is fighting again. He has glooby feelings over Sp4mton leaving without a trace. The M1kes didn’t get something just so for him. He worked himself too hard the day before and overslept, and he had to rush to get onstage for today. Or it doesn’t have to be bad stress. Stress can be happy. Maybe he’s got the whole family watching him today and he’s really excited about it after a week of barely getting any attention! He takes that same 2 liters of coffee and chugs it down in ten minutes before getting on with the show. And not quite an hour in, he’s feeling a strong urge to pee to where he’s struggling not to fidget on camera, even though he knows he hasn’t had that much to drink. He feels like he has to go now, even though he didn’t drink any more than he usually does and has room to hold more. And if he has a weak bladder like it’s popular to imagine, he’s going to have to ask for a cut to a commercial break to get off and run to the bathroom if it doesn’t ease up before his holding muscles fatigue and he ends up peeing his pants onstage or while running off. Why is this?
The faster a bladder fills, the more fullness signals are sent at once, and the stronger urges are felt in response. If more signals that the bladder is full are sent at once, the bladder wants to empty, so it’s going to contract, which is what gives that urgency signal while voluntary holding muscles are still keeping everything in if it’s not a good time to let go. Now, there is some feedback from the voluntary holding muscles that may make urges back off after awhile if the bladder isn’t entirely full, because the body realizes it’s not a good time to pee. But, with more urgency signals being sent at once, that urge is going to be more persistent than one from just a few. It’s not something imagined that drinking something really fast makes you have to pee worse. There’s other factors involved in how fast the bladder fills, like other losses and activity level and blood pressure that we’ll play with when it comes time to talk about M3ttat0n’s hydraulic pressures, but consumption rate has a big influence on its own.
There’s a limit on how much fluid can be reabsorbed by the kidneys in a certain amount of time, so drinking beyond that amount within that amount of time even while dehydrated, and even without drinks with diuretic properties also means that fluid passes right through to the bladder instead of being absorbed to stay in the body longer. That is how the bladder fills faster for that same amount of fluid to cause so much more urgency. Is there actually a calculation to estimate by body weight what this limit is? Yes. So it would be possible to calculate how much fluid and how fast T3nna would have to drink to get over this limit and get himself in trouble. But that takes us into ugly calculus math territory, and even in professor mode, I am not nerdy enough to go there. It’s sufficient to say based on the concept that if T3nna nervously chugs his coffee, he’s going to have pee problems.
Let’s translate the graduate level science of why the urgency is so much worse into English, and debut bad scribble time. It’ll come back again when I get to bladder analysis with Sp4mton and his UTI urgency.
Most with basic education know that the bladder wall is made up of cells, or the building blocks of all live materials, and that’s all there really is to know about what it’s made of that’s relevant here. Bladder wall cells are special in that they can change their shape from round to flat. That’s how the bladder stretches to hold more fluid as it fills up. The cells turn flat, and the bladder wall is thinner and this is also why blunt force against a full bladder can pose a rupture risk in traumatic injuries.
All these building block cells represented by white circles have little nerve endings in them that sense if it’s getting stretched, and send feedback. I am not going to detail every step and all the jargon involved in the signal relay, because that’s just too much. But that’s how our brain knows that the bladder is stretching out and getting full, and how the urgency sensation is generated. If the bladder is filling slowly, then these signals build up slowly, and it might start out as something that is there but not hard to ignore. But, if a whole bunch of fluid is rapidly stretching the bladder out, and more of these cells are stretching out at once, a whole lot of urgency signals are going to hit all at once, and the urge will be felt more strongly. Eventually, the bladder will be full enough this will happen regardless, but it hits sooner and harder when the bladder fills faster. Like so.
This might be all fine for the character who can resist strong urges and really clench and hold as long as their bladder has more room to fill. But again, with the popular idea of T3nna having a weaker bladder, rapid urgency and desperation poses a greater threat, and it’s not hard to imagine a situation where he drinks his coffee too fast!
