****** A Whole New World ******
by Cas_Youre_An_Assbutt
Summary
     This is very sexual, so if you’re looking for smut, you’ve cum to the
     right place–as long as you read the long-ass note ( sorry ) , because
     the character and human anatomy descriptions are there, and you may
     be triggered by what I write. You have been warned.
     ( Seriously. I know that the note is long, but the story–especially
     the smut–won’t make as much sense if you don’t read the human anatomy
     part. )
Notes
     I definitely don’t know everything about Underfell. If this makes you
     unhappy because I “don’t know how their world works” or some bullshit
     like that, get over it. I’ve only picked up what I have here and
     there from reading a few different comics, so I know that I don’t
     know everything. However, this is //my// take on Underfell because
     I’m filling in their characters and world how I want them to be. This
     is merely //based upon// Underfell. If you can’t get over the fact
     that these are //my// plot decisions as the author, read something
     else.
     For those of you who just cum for the smut, I feel. The smutty stuff
     will start in the line with an asterisk, but in the first chapter,
     there will not be any. Sorry, babes.
     I wrote out a long-ass explanation about knowing that my work is
     triggering, how it’s my right–where I live–to post it, and my right
     on this site, as they have specifically designated a main tag for it,
     but it didn’t save, so I’ll summarise. I also explained that I know
     damn well that I’m sexualising a terrible thing. In short, I have
     been verbally, physically, and sexually abused, so I know what I’m
     fucking writing about. I am fully aware that it’s a triggering plot.
     No, I do not condone any of those things. Everyone deals with abuse
     in their own ways. I deal with it by controlling the way it happens
     in my work by, quite literally, rewriting what happened. No, this is
     not exactly what happened to me. I have merely incorporated some
     details. If you will be triggered, do not read my work. Everything
     clear?
     Final note, the character is genderless and named Cas. They’re
     chubby/fat, about..ninety-seven-and-a-half kilograms, or and two-
     hundred fifteen pounds, standing at 1.77 metres, or five feet and
     nine-and-three-quarters inches. The way that I write human anatomy in
     almost all of my books, stories, fanfictions, etc..–excluding plots
     that specifically involve cis, non-binary, and/or transgender
     characters–is that every person has an orifice that becomes slick
     with natural lubrication–unless they have a medical problem or
     something–when its owner becomes aroused, like a vagina. They also
     have something that resembles something along the lines of a clitoris
     and a penis. It can be sexually stimulated, and, through it, one can
     ejaculate–but not urinate, unlike a penis. Also, everyone has mammary
     glands and can carry a child, assuming that they are fertile. Species
     have no effect on one’s ability to become pregnant. The difference
     between “male” and “female” is their ratio of testosterone to
     oestrogen. Their facial and bodily bone structures are affected by
     those levels, but they are easily reversible changes if the person
     wants to start or stop taking a different hormone. This does not
     apply to the Undertale/Underfell characters, as they are magic
     monsters, not human. Their anatomy is completely different and unique
     in their own ways. I will describe everything else more as I write
     the chapters, okay? That’s about it. Happy reading!
***** Chapter 1 *****
     I shove my left hand into its pocket of my jeans, biting my lip as I
nervously glance over my shoulder every few moments, paranoid of possibly being
seen. My fingers fidget with the guitar pick in my pocket, my other hand
clinging to the straps of my heavy book bag and guitars’ double case with my
right hand.
     I continue to ascend Mt. Ebott, slightly out of breath, but I’m far more
desperate to get away from those freaks than worried about being winded.
     Eventually, I reach the top, panting, trying to regulate my breathing, but
it’s..little difficult to do with such thin air.
     I brush my hair from my sweat-dampened face, biting my lip a bit to
suppress a grin, having forgotten that I’d both cut and dyed it how I’ve always
wanted to before I left; fiery red in a short, choppy hairstyle.
     I smile and laugh to myself, suddenly realising that I’m finally free from
those assholes–from everyone! I’ve thought up the perfect plan! No one ever
comes up here because they’re terrified of potentially encountering a monster.
     I’m not afraid, though. If a monster ever were to come through here, I
probably wouldn’t even react. Nothing scares me anymore. Not after..
     I sigh, shaking my head to clear my thoughts before a potential smoke stop
catches my eyes. The last thing my lungs need right now is for me to inhale
anything, I know, but..fuck it. I’m finally free. This deserves a mini
celebration.
     I sit down on the rock I was eyeing after checking it for spiders, ants,
and any other creepy-ass crawlies. I then take out the vape I stole from a
classmate a few months ago. I turn it on to let its atomiser heat up as I look
through my–also stolen–bottles of “juice.”
     After a few moments of shuffling through them, I settle for cotton candy
and put some drops into the cartridge, revelling in its light, sweet scent as
it heats.
     When it beeps, I smile and raise the pen to my lips, taking a long, deep
drag. I hold it in my lungs for a while, excitedly thinking about how free I
feel–how free I am–before exhaling. I watch as the wispy vapours fly out into
the rest of the air, playing with my new lip ring.
     It’s a bit sore, as is the piercing on my tongue, but..eh. I’ll get used
to them. Besides, they aren’t unbearable pains. I’ve definitely gone through
worse.
     After a few badly needed drags, I decide to turn it off because I don’t
want to waste any of it. After all..I’ll be living here for..probably what will
be the rest of my life. I’ll only go back down if I’m desperate.
     When I finish packing that away, I pick up my stuff again, having decided
to look for a place to actually set up to live. As I walk, though, I notice
that there are cracks in the ground, and I, wary of it, step to the side where
the soil is firm before continuing to walk.
     As I continue, however, I realise that the cracks in the ground become
more frequent.
     I bite my lip, assessing my situation, “Shit..”
     I turn around to try to get the Hell out of here, but I see that the
cracks have traveled into the path I just walked.
     Realising that I’m trapped, I sigh, as there is nowhere to step without a
crack.
     I’m so going to regret this.
     I take a step, anyway, to get it over with, and I feel myself fall through
the soil. I turn onto my side as quickly–and as best–as I can in midair–before
I feel myself slam into the ground.
***** Fuck *****
Chapter Notes
     Wow, okay. I posted that, at the time of me beginning to write this
     chapter, forty-five seconds ago, and it has already been read by four
     people. You guys are thirsty and prowling for smut, lmao. Thank you
     for being interested in my work! I appreciate it! <3
     ( At the time of me coming back to my writing.. ) Jesus Christ, when
     I checked back in an hour later, it had //one hundred eighty-seven
     hits!// Now, a week later, it has one hundred ninety-seven! Jesus
     Christ. xD You are thirsty fucks.
     ( Now, at the time of posting this because I finally have time.
     Things have been chaotic lately ) Okay, you are truly thirsty fucks.
     All four hundred forty-two of you. I feel, though. I indicated
     smut–which there will be! I’m working on that chapter, actually. It
     won’t be this one or the next one, but it will //probably// be the
     chapter after that. (: Happy reading!
     I take in a shallow, shuddery breath after I make contact with the ground
as a sharp, resonating pain shoots through my right hip.
    I am so fucked..
    I take in another uneven breath and grit my teeth before shifting onto my
left side. I pull up my shirt and move my pants with a trembling hand to assess
myself, slightly worried about what I might see.
     I definitely bruised the bone. I don’t think that I cracked it, though..
Hopefully..
     I slowly pull my shirt back down and shift so that I can sit up properly,
but I immediately regret doing so.
     I hiss in pain, my right hand darting to hold my hip as I pant slightly.
     Trembling, I force myself to stand, shifting my weight onto my left side
and biting my lip as I take a shaky step forward. I timidly–and sparingly–allow
my weight to fall upon my right side.
     I grimace and pause for a moment, leaning onto my left side, but I force
myself to continue limping forward as my right hand cradles my injured hip.
     After, kind of, teaching myself how to now walk like this, I find my stuff
and swing it all onto my left shoulder to lessen the weight on my right side,
telling myself that I’ll check it all for damage later.
     I probably broke my vape pen’s charger.. Damn it..and my guitars are
probably fucked..
     Along my way, I find a long, wooden stick lying on the ground. I carefully
pick it up, thankful that I can now bear my weight on something other than my
fucked hip. With a slightly broken smile, I continue down the dimly lit
corridor of the..cave, I suppose, into which I probably fell. I don’t really
know where I am.
     Panting, I stop when I reach an arch that appears as though it had been
cut out of the wall a very long time ago, the markings appearing almost..royal?
     Oh God..
     Though every fibre of my very being screams at me not to enter into
whatever new Hell awaits me in the next room, I continue.
