ASRIEL LOVES FEET
PART 1
It was yet another calm, peaceful and innocent morning in the Underground, just after the events of previous fanfic Alphys' Bad School Day, and all of the monster kids, not to be confused with Monster Kid himself, were fast asleep in bed; today, however, we're going to be focusing on the perspective of Asriel, who was currently sleeping on the cold wooden floor in the attic of Toriel's three-story foster vacation home in Snowdin with Alphys and Undyne...a house that the four of them were literally the only residents of, by the way.
"GAAAH!" all three of the kids woke up and screamed as the hot-pink, glittery, cat-eared, anime-girl-faced Mew Mew Kissy Cutie alarm clock on the bedside table next to Alphys' and Undyne's suddenly went off at the least expected possible moment (6:00 AM, just as always), scaring the living bejeezus out of them!
"Welp, guess it's time for us to get ourselves ready for school..." Alphys sighed, leaning forward and yawning and scratching her sides and rubbing her tired, crusty eyes while Undyne did the same.
"God, why am I suddenly so turned on right now? Like, somehow even more so than USUAL with those two?" Asriel thought to himself, cocking an eyebrow in confusion as he watched the scaly little weeaboos grab their clothes out of the attic's closet and head straight down through the attic hatch onto the third floor...barefoot and in their women's underwear, of course.
"Alright, let's see what we've got on the news this morning..." Asriel shrugged and sighed as he lazily trudged his way over to the attic's couch, plopped himself down on it, grabbed the remote off of the coffee table and hit the POWER button, turning on the plasma-screen TV and resting his head on his hand in boredom while Alphys and Undyne not-so-secretly took yet another hot, steaming, 12-year-old (hint: all three of them were twelve) shower with each other in the third-floor-hallway guest bathroom downstairs.
AUTHOR'S NOTE: Yes, despite having only been born about three months ago, Toriel's adorably fluffy new son Asriel had somehow already assumed the form AND additionally amassed the knowledge of a seventh-grader; it's magic-superpower logic, don't question it.
"Greetings, everyone; I'm your daily host, the ever-so-handsome and fabulous Mettaton EX, and welcome to the local morning news!" Mettaton swung around in his office chair and announced at the television broadcasting station at MTT Resort in Hotland (right next to the school, which he was now the official dance instructor at), crossing his legs atop the table and pulling off his hot-pink high-heeled boots to reveal his gorgeously shapen, blindingly lustrous and fabulously masculine soles to his audience; meanwhile, Asriel pounced right up to the television, pressed his face against the screen as if literally magnetically attracted to it, and began excitedly drooling and panting and wagging his fuzzy little tail like a dog in response, his penis stiffening rather noticeably and protruding extensively from his underwear as he did so.
"Today at Hotland's world-hated, I mean renowned, MTT Middle School conveniently located right next to my equally world-famous MTT Resort, I've decided to make this completely random and otherwise unmeaningful day of December into the National Barefoot Day! Remember, everyone, NO SHOES OR SOCKS WHATSOEVER!" Mettaton laughed as he crossed his glamorously long and slender legs atop his desk and teasingly wiggled his deliciously, girlishly painted toes at the audience; meanwhile, Asriel was merely blushing and sweating with hypnotic arousal as he masturbated furiously with one hand and pointed suggestively into his mouth with the other.
About the next ten minutes or so of Mettaton's morning news bulletin was spent on him mercilessly torturing the audience with the temptation to lick and worship his beautifully shiny metallic soles; needless to say, Asriel only made it through about two minutes or so before finally creaming himself.
MEANWHILE, IN THE SHOWER...
"Oh, yeah, lather me with that smooth silky soap...LATHER ME LIKE YOU FREAKING MEAN IT!" Alphys and Undyne moaned lovingly to each other as they twirled about and french-kissed each other in the shower, hugging each other tightly in only the warmest of embraces as they romantically fondled each other's peculiarly underaged breasts and seductively rubbed body wash all over each other with their bare, scaly hands, causing Alphys' big chubby tail and dainty little toes alike to curl with pleasure as she blushed and panted intensely with arousal, struggling to resist fingering herself to the point of climax while Undyne routinely did the EXACT same, culminating in the two of them leaning toward each other and interlocking their lips together in a big sloppy kiss the likes of which were rarely seen outside of James Bond films...when suddenly, they both heard the rather distinct noise of Asriel moaning and bleating orgasmically upstairs!
"Asriel, I SWEAR TO GOD, if you hid one of Alphys' freaking spy cameras in the shower again, so help me, I am going to freaking tear you LIMB FROM LIMB!" Undyne yelled angrily at Asriel as she climbed right back up the ladder into the attic and flipped open the hatch forcefully.
"Um, actually, I'm the one who places those, and even then, it's mainly so that I can jerk off to Asriel!" Alphys whispered nervously into Undyne's ear, glancing rapidly from side to side.
"OH...MY..." Undyne gasped and blushed in shock as she saw Asriel dizzily, unconsciously sprawled out on the splintery wooden floor right in front of his stupidly fancy and expensive television, with his gooey white semen oozing down the screen in an articulately fingerpainted box-Mettaton shape while Mettaton himself was busy flamboyantly showing off his feet on screen.
"Asriel, WAKE UP! What in Mew Mew's unholy name just happened?!" Alphys asked Asriel urgently, violently shaking him awake and glaring sternly into his still-cartoonishly-swirling eyes.
"FEET...FEET...FEEEEEEEEET..." Asriel moaned ghoulishly as he sat right back up on his hindquarters and outstretched his arms toward Alphys' adorable little feet in a profoundly zombielike fashion.
"SNAP THE F%#& OUT OF IT!" Alphys yelled frustratedly at him, slapping him in the face to knock him back into focus while Undyne just rolled her eyes and shook her head in disgust.
"Okay, okay, look; I can explain!" Asriel stammered awkwardly, reaching for the remote (which luckily was still laying in the exact same spot on the coffee table as before) and shutting the television off while Alphys and Undyne impatiently tapped their feet on the ground, prompting him to firmly shut his eyes so that the temptation to lick the sweaty little beauties wouldn't distract him from delivering his message as he cleared his throat, drummed his fingers together anxiously, and began speaking.
"You see, there was this, like, NEWS bulletin, right? And, like, Mettaton was, like, teasing me with his feet and stuff, and then he, like, told me that it was National Barefoot Day at school, and GODDAMNIT, I'M SO FREAKING SCARED!" Asriel curled up into a ball and sobbed humiliatedly while Undyne and Alphys smugly filed each other's razor-sharp fingernails.
"And WHY exactly are you getting so insanely worked-up about such an incredibly mundane and boring thing happening, may we ask?" Alphys and Undyne teased him, sitting down together right in front of him and wiggling their wholesomely bright-red-painted toes at him.
"Um...w-well...I t-think I might h-have quite a bit of a...f-foot fetish now, mostly thanks to him and Toriel..." Asriel stammered reluctantly, blushing deeply and hanging his head in shame.
"Oh boy, this kid is going to be SO much fun to tease!" Alphys literally put her foot in Undyne's mouth and moaned with arousal as the lovable fish lady sucked her scrumptious little toes like lollipops.
"Man, TELL me about it!" Undyne laughed, briefly removing Alphys' foot from her mouth into speak as she crammed her own tantalizingly soft, scaly and sweaty (and in this case, web-toed) foot into Alphys' mouth, moaning with pleasure as Alphys' moist, slimy, ever-so-wonderfully-dextrous lizard tongue teased over the ball and arch of her foot like there was no tomorrow...or perhaps even no one secretly watching through security cameras, for that matter!
"HEY, COME ON, THIS IS FREAKING PRIVATE AND YOU KNOW IT!" Toriel yelled at the cameraman in her master bedroom downstairs on the first floor as she laid down on her soft cushiony bed and gently fingered herself to Alphys' and Undyne's adorably girly and lesbian antics.
"Welp, here goes nothing...I sure hope that this day at school doesn't turn out TOO embarrassing!" Asriel laughed (while Alphys and Undyne both shuddered and cringed from the mere thought of some of the things that had ended up happening to them in the previous story) as he smugly stood up as straight as he possibly could, puffed out his chest and marched out blindly like a British army soldier...which, of course, led to him falling through the hatch like a doofus!
"Wow, are you okay?!" Alphys and Undyne both laughed uproariously as the former began rigorously licking Asriel's fully exposed left sole while Undyne began fervently licking the right.
"APART FROM FEE-HEE-HEELING LIKE I'M ABOUT TO EXPLO-HO-HO-HODE WITH LAUGHTER, I SUPPOSE SO-HO-HO-HO!" Asriel laughed hysterically, pounding his fists on the floor and begging desperately for the two of them to stop tickling him as their tongues teased over his surprisingly soft paw-pads, wormed their ways into his arches and even began digging fiercely into the dainty little gaps in-between his toes, eating his deliciously built-up, hairy and nasty toe jam in the process. (Just imagine how much toe jam he would produce if he DID wear shoes and socks...)
"Damn, we should try spreading that stuff on TOAST sometime!" Alphys laughed, licking her lips, patting her belly and letting loose a loud mayonnaise-scented burp while Undyne wetly and sloppily smooched the lustrously padded heels and balls of Asriel's feet and gave them a big warm fish hug while Toriel inadvertently walked up onto the third floor and caught the three of them right in the act!
"My dear and beloved children, please explain to me right this instant: pardon my language, but seriously, what in the actual foot-licking F%#& am I witnessing right now?" Toriel calmly and collectedly asked them (albeit with a profoundly confused and disturbed look on her face) as Undyne humiliatedly put her hands over her crotch in a laughable attempt to hide the brightly glowing blue boner underneath her blue jeans while Alphys glared sassily at her in disappointment.
"Um...w-well, you see, it's National Barefoot Day at school today, and...well, I think the three of us have a rather embarrassing confession that we need to make about ourselves right about now..." Undyne stammered nervously as she stood up and crossed her legs adorably in sexual discomfort while Asriel went into the bathroom and took a shower to deliberately avoid drawing any more attention to himself for the time being out of sheer embarrassment and humilation.
"W-well, you see, t-the thing is, w-we both kinda h-have...we both kinda have..." Alphys stammered awkwardly and bit her lip, drumming her fingers together and trembling embarrassedly.
"Let me guess; you two and Asriel both have only the absolute nastiest of freaking FOOT fetishes, don't you? Oh, you cheeky little SLUTS of girls!" Toriel laughed and giggled teasingly, simultaneously patting the two of them lovingly on their backs and giving them a great big group hug.
"B-but...Asriel's a BOY!" Alphys stammered in confusion, brushing Toriel's hand away.
"Right, and I suppose YOU'RE a buck-toothed, men's-glasses-wearing, bigfooted, Sonic-quilled GIRL!" Toriel chuckled with a playful note of sarcasm, patting Alphys on the head while the poor lizard girl glared evilly at her, reached into the pockets of her lab coat and made an angry post to Tumblr on her iPhone about how everyone constantly mistook her for a guy.
"Hell, for that matter, I guess you could even say that Mettaton DOESN'T look like a freaking girl, while we're at it!" Undyne laughed uproariously, clutching her chest merrily with mirthful glee.
"Um, for the record, Mettaton actually kind of IS a girl, you know!" Alphys reminded her, walking over to her and somewhat irritatedly (albeit lightly) smacking her right on the chubby fish cheek...of her scaly aquatic fish ass.
"OH." Undyne said flatly, her eyes widening in surprise as Toriel grabbed the two of them by the hands and dragged them down into the kitchen to get them to finally stop talking for at least five seconds.
Once Asriel had finally gotten out of the shower and redressed himself, the four of them gathered together at the breakfast table and briefly discussed more urgent matters (over their cereal, of course) regarding the so-called foot-fetish "crisis" that Toriel's kids were very clearly and majorly overreacting to.
"So, what's all this talk about Asriel being the absolute worst-off in this situation? What exactly makes HIM such an udderly special Snowdin-flake, might I ask?" Toriel giggled, shoveling a nice big spoonful of piss-flavored Cheerios into her mouth and glaring seductively(?) at her son.
"MOM!" Asriel groaned, rolling his eyes and facepalming from Toriel's god-awful jokes.
"Well, for starters, he seems to have the absolute WORST case of foot fetishism out of ALL of us!" Alphys explained, setting down her spoon so that she could gesture ominously with her hands while Undyne just rolled her eyes and continued eating her cereal like a normal person.
"He could be crawling underneath this table like a disgusting, rotten plague at this very MOMENT as we SPEAK...LICKING HIS LIPS...DROOLING RABIDLY AT THE MOUTH...BARING HIS FEET, I MEAN, FANGS...WELL, THAT TOO, I GUESS!" Alphys hissed and whispered cheesily and melodramatically to her bored and confused audience while Asriel crawled underneath the table and bit Undyne right on the webbing in-between her big toe and her index toe!
"YEOWWWCH!" Undyne jumped in her seat and shrieked in pain, pulling out a rolled-up copy of the weekly local newspaper from her pocket (after all, in the magical world of monsters, storage spaces were often considerably more than met the eye) and beating the viciously growling Asriel over the head with it until he finally let go of her foot, leaving a large bleeding cut in her toe-webbing as well as nasty, foamy animal slobber all over her toes in general.
"Um, e-excuse me for a m-moment; I h-have some very urgent m-matters to attend t-to!" Alphys stammered and blushed embarrassedly as she grabbed Undyne's now-aching right foot by the ankle and lovingly kissed her boo-boo, sucking the blood (which was actually liquid red dust, by the way) out from her cut and sucking her sexy little mermaid toes as if their lives depended on it.
"HALLELUJAH!" Undyne could feel her toes metaphorically squealing with delight as Alphys began singing This Little Piggy just for the sake of utterly humiliating her even further.
"This little fishy swam to market!" Alphys sang teasingly with an incredibly smug wink and an equally sly grin as she lovingly sucked her girlfriend's right pinkie toe, causing Undyne's ears to droop downward with relief as she moaned and blushed with deeply humiliated pleasure.
"This little fishy bought a bunch of Trojan condoms thinking that they were candy!" Asriel sang as he eagerly joined in the fun and began passionately sucking on Undyne's left pinkie toe while Toriel just speechlessly sat there and watched the madness unfold, having literally no idea how to react to the sight of something so utterly ridiculous happening right before her very eyes.
"This little fishy went and fed them to the big-ass literal dogfish living in the aquarium in her backyard!" Alphys sang, raising her eyebrows seductively at Undyne as she sucked and sucked and sucked on the poor fish girl's right next-to-pinkie toe, humming and smiling with delight.
"This little fishy then began to curiously, stupidly wonder why her pet was starting to get so incredibly f%# ing SICK!" Asriel sang as he wetly, sloppily sucked Undyne's left next-to-pinkie toe with all of his succulent, dripping might.
"And so this little fishy went to the vet and asked her why her pet had gotten so f%#&ing sick, and the vet told her that she was a f#&%ing idiot and should have already known right from the get-go!" Alphys sang, teasingly biting down on Undyne's right middle toe with her big nerdy buck teeth while Toriel took a seat on the floor right next to them and began eating a tub of magic popcorn.
"And so sure enough, this little fishy's dog and all of her unborn babies were never heard from again, which of course made this little fishy very, very SAD!" Asriel chuckled somewhat sympathetically, sucking fervently on Undyne's left middle toe and teasingly nibbling on its ever-so-pointy little tip as tears of sadness and regretful sorrow began to leak from the poor girl's eyes.
"And so this little fishy, in wonderfully sincere honor of her poor pet's miserable death, unceremoniously tossed her into the nearby river like a sack of rotten old pota-TOES!" Alphys sneered angrily at Undyne, taking a brief two-second break from sucking her right index toe just to slap her in the face.
"And at that very moment, this little fishy suddenly realized the true extent of just how badly she had f%#&ed up!" Asriel sang teasingly as he sucked and sucked and sucked on Undyne's left index toe.
"And from then on, this little fishy vowed never to own a pet again, because she was apparently just too f%#&ing stupid and crazy to be able to properly handle one in the FIRST goddamned place!" Alphys sneered infuriatedly, biting down brutally hard on Undyne's right big toe (causing her to shriek in pain and also causing said toe to turn purple and swell up, of course) and kicking her right in the face.
"But alas, when this little fishy met this adorable little dinosaur, she decided to revoke her vow and have herself a wonderful pet girlfriend named Alphys, whom she would ultimately end up keeping for the rest of her entire stinking LIFE!" Asriel laughed as he gluttonously chewed and sucked on Undyne's left big toe, then grabbed both Undyne's left foot and Alphys' right foot and respectively placed them onto the left and right sides of his throbbing, rock-hard penis.
"Their relationship with each other was so utterly wonderful and beautiful that I swear to God I'm literally going to CUM in, like, TEN FREAKING SECONDS if these two keep it up...OHH...OOOOOOH...AHHHHHHHHHHHHH!" Asriel moaned orgasmically as he used Alphys' and Undyne's beautifully soft and scaly (fish and lizard) soles to give himself the two-person footjob of a lifetime, causing his dick to violently spasm and spray out a cavalcade of hot, sticky semen all over Toriel's utterly speechless, thoroughly disgusted and wholly disbelieving face!
"Okay, I think that's enough FUN for one morning, thank you very much!" Toriel sighed, wiping the gooey, sticky dick-slime off of her face with a wet paper towel and shooing her disgustingly naughty kids out the door, leaving them to run literally all the way from Snowdin to upper Hotland just to go to freaking school while she just called up a magical flying taxi on her cell phone.
(Did I mention yet that she was the English teacher at MTT Middle School?)
