Notes
See the end of the work for notes
Once upon a time in the land of Undertale, Monster Kid had a Great Idea. His
beloved idol, the great Undyne, had arms with which to wield weapons and
perform heroic deeds, yet he did not. The solution was clear! He must seek aid
from the most knowledgeable monsters in the land. He set out to speak with
Dr.Alphys, the royal scientist.
Oh Jeez, Oh gosh! Thought Dr.Alphys, in her home/laboratory, poring over
curious tomes of illustrated human literature. That human male is so small and
youthful next to that mature and plush human female... and he's so hesitant!
It's so cute! Oh, if only someone like Undyne would be so aggressively sexual
to little old me... She was shocked from her perverted reverie by a knocking at
her lab's door. Checking her security cameras, it was none other than some
Monster Kid kicking at her door. Pressing the exterior intercom button, she
nearly snarled into the microphone "Quit kicking my door, you little twerp!
You're gonna get in trouble!"
Monster Kid was only momentarily frightened by these threats, he knew he had a
critical mission. "Dr.Alphys! Of course I'm kickin' your door... can't you see?
I need your help! You're like the best monster around to help me! Please!" he
began to plead. Inside, Alphys was puzzled, and then embarrassed. The kid
didn't have any arms, of course he would kick at her door, he couldn't knock or
reach a doorbell or anything. Outside, Monster Kid continued his plea. "You're
great at like making machines and robots and stuff, you can build arms for me!"
Alphys' ego was stroked and her curiosity was piqued, her door slid open and
Monster Kid scampered inside excitedly.
"H-hey there, uh, lil' buddy! Sorry for my outburst over the intercom, I was
kind of absorbed with some, research, an wasn't expecting any visitors today."
said Alphys, her nervous frown already starting to turn into a smile seeing how
joyful and energetic Monster Kid was. He was looking to and fro in her
laboratory, oohing and ahhing at the various screens and doodads. "Ahem, you
mentioned you needed help with... robot arms?" she said, trying to get the lad
focused back on his purpose.
"Yeah, oh yeah!" Monster Kid began, "I was thinking that you could make arms
for me! Or help me make arms for myself. I can kind of use magic to lift and
push things a little bit sometimes but if I had arms then I could just use
those! I could focus on learning to use my magic in other ways, like blasting
bad guys! Or we could put guns in the arms? And I could beat up villains and be
a big hero like Undyne!"
Alphys struggled to take in Monster Kid's rapid blurted explanations and
requests, but the name of Undyne stood out. "Undyne? You like her too huh, well
I guess everyone does..." "OR ROCKET FISTS! Can we do rocket fists!? And
yeah!!! Undyne's the greatest! The bestest! The strongest and most heroic
heroine to ever do heroing! That eyepatch makes her look so tough! And she's so
tall and athletic, and, uh..." Monster kid began to slow down finally, looking
down at his feet awkwardly. "So, uh, yeah, robot arms, could we..."
"Sure thing!" Alphys replied cheerfully, pulling some measuring tape from a
labcoat pocket. "We'll have to measure your uh... shoulder-type area first, so
we can make a proper harness to hold the arms onto you. You'd better uh, take
off the shirt so we can get the most accurate..." her yellow face turned a
shade paler as she realized what she just said, then turned nearly orange as
Monster Kid obeyed. She felt a throb in her cloaca as she watched Monster Kid
shimmy out of his striped shirt and stand bare before her. He was so cute! So
obedient! He didn't have any arms to defend himself with, she could push him
over and
"Are you okay Dr.Alphys? You froze up and you're breathing all heavy all of a
sudden. Do you need me to get help?" Monster Kid asked as he peered at her
quizzically. Alphys shook her head and quickly took his torso measurement, then
put the measuring tape away. "Alright, you have a seat on that stool, I'll
wheel in some materials for the harness and some robot limb parts..." "I can
help you gather the stuff!" Monster Kid offered, as Alphys moved to leave the
room. "Haha, you're a real helpful... little fella, aren't you?" replied
Alphys. "You betcha! It's like we say in the fanclub, when we're faced with a
problem we always ask ourselves, "What Would-"" "-Undyne Do!" Alphys finished
the saying for him.
"Oh my GOSH! You're in the online fanclub too Dr.Alphys!?" Monster Kid nearly
jumped in excitement. "IN the fanclub? Buddy I STARTED it!" Alphys replied.
"YOU'RE WEBMISTRESS FISHYFANGIRL42!!!" Monster Kid shouted, skipping around
joyfully. "I've read ALL your Undyne fanfics! and I've faved ALL YOUR FANART!
and-" Alphys interjected "Y-you seem familiar now too... lemme guess,
UndynesUnderstudy69?" "OH!!! MY!!! GOSH!!!"
Alphys and Monster Kid spent the next half hour exchanging in-jokes from their
online Undyne fanclub that would have been incomprehensible to anyone else.
They giggled together and shared gossip and stories about chats and roleplays
with other fanclub members. Alphys hadn't felt this relaxed and on the same
wavelength as someone in person like this in a long time. Their initial project
of building arms was nearly forgotten.
"I uh, I always thought you were a bit older when we chatted online, Wait...
how do you type?" asked Alphys. "Sometimes I can use my magic to press the
keys, but other times i just use my toes, I have great toe dexterity." At this
he rocked back on his stool and wiggled his toes. "Heh! Wait a second... you
said..." Alphys paused in thought as a sense of dread entered her heart. She
remembered UndynesUnderstudy69 faving and commenting on everything she'd made,
even the raunchy stuff. ESPECIALLY the raunchy stuff, often leaving detailed,
horny comments and ideas for more stories. "Ah, oh heck..." Alphys was becoming
flustered. "Y-you know you're not supposed to be going into... certain parts of
the fanclub site, till you're older." Monster Kid began blushing orange now
too. "Yeah, yeah, sorry about that..." he said, crossing his legs and looking
away. "It's just, Undyne's so amazing and strong and cool and HOT, everyone
knows it. You capture our adoration for her perfectly! You capture the longing,
how much we wish she'd notice..."
Alphys gulped and felt cold sweat roll down her scales. Monster Kid was so cute
when he blushed, and he still hadn't put his shirt back on. "Maybe I could be
your Undyne tonight." Alphys immediately froze in terror. Had she said that out
loud? Monster Kid was staring at her quizzically. "Did I say...? Ha ha I mean,
Maybe I could... see your fungi tonight? Ah..." "Fungi? I don't collect
mushrooms Alphys." "Ha! Ha oh well silly me well you should head home it's
getting late we can make you somenewrobotarmssomeothertime" She stood and
picked up Monster Kid's discarded shirt, almost trying to shoo him away.
Monster Kid didn't move. "I heard what you said first perfectly, Dr.Alphys."
"It was just a silly little joke, o-okay? I know, not a good one, not
appropriate, you need to move along now." Alphys said, panic rising in her
heart. "Don't take this the wrong way, Alphys, but... " Monster Kid began "I
really don't think you'd be very good at roleplaying Undyne, especially not
LARPing as her." He leaned forward "Me on the other hand... maybe I could be y-
your Undyne, Dr.Alphys?"
"Neither of us is much like Undyne, Monster Kid, that's why we look up to her
so much... but I remember our club's motto. What would Undyne do? She
wouldn't... at least I don't think she would, approve of the direction this
conversation took." said Alphys. "That's funny," Monster Kid replied, "'cause
when I think about what Undyne would do here, shirtless and face to face with
someone as cute as a blushing Dr.Alphys, I think she'd-" at this he leaned
forward off of his stool and kissed her. Alphys didn't pull away. His little
tongue clumsily wiggled into her mouth. Alphys still didn't pull away. She had
been so lonely for so long.
Monster Kid broke the kiss and sat back, panting and watching for a reaction.
Alphys looked down at the shirt she held in her hands, and then to Monster Kid.
She dropped the shirt and began to undo her labcoat, exposing her soft
underbelly. Monster Kid watched silently as the older woman lizard disrobed,
his head swimming in overwhelming sensations. Before she was done he was
already down off his stool, curiously and insistently poking his head under her
coat. Alphys reached down and guided his head toward her wet and needy cloaca.
Monster Kid was not an experienced or skilled lover, but Alphys didn't care,
she was thrilled to have any lover at all. Monster Kid energetically got to
work, nudging, sucking and licking, Alphys encouraging him and wordlessly
instructing him with her moans and movements.
Alphys pulled Monster Kid away from nibbling at her hole long enough to make a
makeshift bedding on the cold laboratory floor out of their discarded clothes.
She lay down upon it, looking up at him. His modest hemipenis had everted and
throbbed with his rapid heartbeat. "Hey... it just occurred to me, h-how do you
jack off with no arms?" she asked. "Not very often!" He replied with a smile
and a giggle. "A-alright then, let's see you live up to that last part of your
name, UndynesUnderstudy69." They both snorted a little at this, and Monster Kid
wasted no time, climbing onto Alphys and preparing to dive at her cloaca and
hemiclitores again. He paused, gasping and moaning when Alphys took him into
her mouth. "Mmm?" She enquired, "It's good, k-keep going please." he answered,
"You foo" she finished with a mouthful of lizard dick.
Monster Kid clumsily but enthusiastically returned to pleasing Alphys' hole.
For her part, Alphys was both excited and frightened. She knew what she was
doing was wrong, but it felt so, so right. She could get in trouble. Was she
hurting Monster Kid by doing this sort of thing with him? Monster Kid, for his
part, sucked and bucked atop her, lost in animal sexual lust. Alphys gave in,
too. They soon came together, Monster Kid's snout flooding with Alphys' juices
as she squirted, Alphys' mouth with Monster Kid's modest amount of thin cum.
They both tried to swallow a bit, but gave up and spat.
Panting, Monster Kid rolled off of Alphys' belly and tried to snuggle up
against her. Alphys, though, was consumed with dread. She wiped her mouth and
looked at her wet hands. "I'm so fucked up." she said. "What have I done. I'm a
criminal. I, I'm so sorry, Monster Kid, I shouldn't have done this, I shouldn't
have let this happen, I-" Monster Kid frowned and interjected "Dr.Alphys, I'm
sorry, I only wanted us to... to feel good together, I didn't mean to make you
sad or scare-" They looked at each other with mutual confusion and concern.
"Let's... let's get washed up, we can talk this over..."
They put their discarded clothes into Alphys' washer and dryer. They showered
together, not seeing any sense in being suddenly bashful with each other after
what they've already done. Alphys quietly and awkwardly helping Monster Kid
scrub up. "Well, guess your new arms will need to be waterproof too, huh?" she
asked. "Yeah, that's a good idea!" Monster Kid exclaimed. They toweled off, and
continued talking, trying to come to terms with their activities.
"Are you sure I didn't hurt you? And you don't hate me? And you're not going to
call the police and have me arrested and killed for abusing you?" Alphys asked
"Ch-chill out Dr.Alphys!" Monster Kid exclaimed. "Look... I know Undyne
wouldn't backstab you after smooching you! So I won't either! It felt good! Th-
thank you!" Alphys sighed at this. "No, you shouldn't be thanking me... I
should be thanking you for not turning me in. Look, you're a great kid, Monster
Kid, but we should probably find folks our own ages for this sort of thing."
Monster Kid looked thoughtful about this and nodded.
"You run along home, I've got your measurements written down still, I can work
on those arms without you needing to visit until it's time for you to pick them
up." Alphys said, helping Monster Kid pull on his striped shirt fresh out of
the dryer. Monster Kid nodded and left.
 
-SOME TIME LATER-
Alphys picked around the garbage dump zone, hauling a sack on her back. It was
a great place to grab electronics and bits of metal or plastic that fell from
above, perfect for making new robot arms for someone. She neared the bottomless
trash pit. She stared into the void. She thought about jumping in, ending it
all. She always did, every time she visited the dump, really, but this time it
was especially intense. She felt she deserved it now more than ever, after what
she had done.
But dead lizards can't finish building robot arms. She turned and headed back
to the lab.
End Notes
     sorry if i spent too much time focusing on how guilty alphys feels,
     but having her be confident about this sort of thing would have been
     too out of character, hence why monster kid took the lead. anyways
