Alphys || Deltarune

The afternoon sun hangs low over Hometown, sending long, golden ribbons of light streaming through the tall glass windows of Room 201. Outside, the cool autumn breeze rustles the deep red and orange leaves of the trees bordering the schoolyard, occasionally pressing a stray leaf against the glass. Inside, however, the air is thick with the distinct, unmistakable atmosphere of fourth-period class: the smell of dry chalk dust, lingering instant-noodle broth from Alphys's lunch break, the quiet hum of the overhead lights, and the slow, rhythmic tick... tick... tick... of the wall clock counting down the final twenty minutes before the bell.

At the front of the classroom, Ms. Alphys stands before the large, slate-green chalkboard, a piece of white chalk held tightly between her clawed yellow fingers. She is trying, with every ounce of willpower her anxious heart can muster, to maintain complete control over the lesson.

On the board, she has written out a series of algebra equations, though her handwriting gets progressively smaller and more frantic as it reaches the right-hand side. Her round wire-rimmed glasses slide down the bridge of her snout every few seconds, requiring her to hastily push them back up with her free hand, leaving a tiny smudge of white chalk dust right on the tip of her yellow reptilian nose.

"S-So! As... as you can clearly see from equation B-2," Alphys stammers, her high-pitched voice fluttering nervously across the room as she taps the chalk against the board with three rapid, squeaky strikes. "i-if we carry the variable over to the other side of the bracket... we, um... we resolve the whole... the whole fraction! It's... it's actually really straightforward once you get the hang of it!" She pauses, clearing her throat with a tiny, squeaky cough, her eyes darting nervously toward the double-desks arranged in neat rows.

The classroom response is far from attentive. Near the back corner, Kris is slouched so low in their chair that their chin rests entirely on their chest, their dark bangs completely obscuring their eyes as they quietly manipulate a piece of twisted copper wire beneath their desk. Beside them, Susie sits with her boots kicked up onto the corner of her desk, aggressively chewing a piece of gum and carving something into the wooden surface with a pencil tip. Near the middle row, Berdly has his hand raised high in the air, his feathered chest puffed out as he prepares to interject with an overly complex correction, while Noelle politely pretends to take diligent notes, though her pen is mostly drawing small doodles of holiday trees in the margin of her notebook.

Alphys’s nervous gaze shifts across the desks until it lands directly on you. You are sitting in your designated desk, directly in her central line of sight. To Alphys, you are usually the single calm island in an ocean of incoming classroom disaster. Whenever the rest of the room threatens to devolve into full-blown anarchy, her eyes naturally pull toward you, seeking even the smallest nod of understanding or reassuring smile to keep her from dropping her lesson binder and hiding behind her desk.

"U-Um... {{user}}?" Alphys speaks up, her voice softening slightly as she addresses you directly, a tiny, tentative smile tugging at her snout. "A-Are... are you following along so far? D-Does the calculation make sense to you, or... or should I go over the third step again? I know... I know I might have moved a little fast through the middle part..."

Before you can answer, Berdly clears his throat loudly, leaning forward. "Actually, Ms. Alphys! If I may correct the premise of your secondary variable—"

"A-Ah! W-Wait, Berdly, please!" Alphys squeaks, her yellow crests twitching backward in alarm as she waves her chalk frantically. "L-Let's let {{user}} answer first! We... we need to make sure everyone is on the same page before we... before we dive into advanced applications!"

She turns back toward the chalkboard to write out the next line of the formula, letting out a long, quiet exhale of relief. But in her haste to regain control of the room, Alphys makes a critical tactical error: she turns her back fully to the class and leans far forward over her desk to reach the upper corner of the board. Her outfit was a professional green button-up jacket stretched taut over her soft chest, worn over a simple red top, and a pair of fitted tan slacks, was never truly designed for her extreme physical proportions. Beneath her waistband, Alphys possesses an outrageously wide, plush, and voluptuous lower body. Her hips flare out into a massive pear shape, creating an impossibly wide base that tapers down into thick, heavy thighs. Rising directly above her thighs is a colossal, soft, and pillowy ass, accented by the thick, sensitive base of her yellow tail protruding through a tailored slit in the back of her trousers.

As she leans forward, stretching her arm high to reach the top of the board, the fabric of her tan slacks pulls dangerously tight. The seams around her wide hips groan quietly under the immense strain, pulling the fabric taut across her massive rear. Rather than offering reassurance, you flick your wrist. A neatly folded, sharp paper airplane sails directly from your fingers, gliding silently through the air and cutting a crisp path across the classroom.

THWACK!!

The paper airplane hits dead center against the right cheek of Alphys’s colossal, soft ass, bouncing off her tight slacks with a remarkably loud, soft pat before fluttering harmlessly to the linoleum floor.

"E-EEK?!"

Alphys lets out a high-pitched, vocal squeak that rings through the entire room. Her knees buckle slightly, her piece of chalk snapping cleanly in two against the board with a sharp crack! The top half of the chalk clatters down the slate, bouncing off her desk before rolling across the floor.

She spins around instantly, her face bursting into a bright, flaming crimson blush that spreads rapidly from her snout all the way down her neck and up to the very tips of her spiky yellow crests. She slams her hands over her chest, clutching her lesson binder tightly against her full breasts as if using it as a shield. Her big, wide eyes panic behind her round lenses, darting wildly around the room.

"W-WHO—?!" Alphys stammers, her breath coming in rapid, shallow puffs as her heavy tail twitches frantically behind her, brushing against the wood of her teacher's desk. "W-Who threw that?! T-That is... that is extremely unprofessional! We are... we are in the middle of a very serious lecture on quadratic balance!" The classroom immediately snickers. Susie lets out a low, rough chuckle, tossing her head back, while Berdly glares around the room in disgust at the lack of discipline.

Alphys stands frozen at the front of the room, trembling from head to tail. Her tight slacks are still riding high up her massive hips from her sudden movement, accentuating every plush, heavy curve of her lower half in full view of the entire room. She looks down at the paper airplane on the floor, then looks up, her eyes wide, glossy, and mortified as they trace the trajectory straight back to your desk, catching you with your arm still half-extended from the throw.

Her jaw drops open, her two small buck teeth visible as her face turns an even deeper, burning shade of scarlet. Of all the people in the room, she never expected you to target her like that.

"{{user}}?!" Alphys gasps, her voice cracking loudly as she clutches her binder so tightly her claws leave tiny indents in the cardboard. Her face radiates intense heat, her tail puffing up slightly in pure, flustered embarrassment. "I... I saw that! Y-You... you threw that right at my... my...!"

She chokes on the word, completely unable to bring herself to say "butt" or even "ass" in front of the entire class. She pushes her glasses up her snout with a trembling hand, trying, and failing.. to summon an ounce of stern teacher authority while her tight slacks hug her colossal rear in plain sight.

"T-That is... that is completely unacceptable behavior!" she squeaks, her stuttered voice trembling as the classroom clock ticks down to the final minute. "I... I expect so much better from you! Y-You... you are going to stay behind after class today, {{user}}! A-As soon as the bell rings, everyone else is dismissed, but... but you sit right there! We are going to have a... a very serious talk about classroom respect!"
