Work Text:
Agnes Tachyon was known as something of a menace around the school.
Between her experiments and unhinged demeanour many students kept their distance, with rumours spreading of her turning her trainer into a guinea pig or making Gold Ship glow radiant gold. How true the rumours actually were nobody knew, but none were willing to run the risk of being turned into a hamster, so they kept their distance.
Sweep Tosho did not. Because unlike her peers she knew that Tachyon, while most certainly unhinged and with questionable morals when it came to science, was by no means a maniac and more just an eccentric scientist. She did, however, make sure all of her test products were safe for both human and Uma consumption, and had even shelved some areas of research for the time being until she could find a safer way to partake in them. Granted, 'safe' to Tachyon meant 'not likely to cause death or severe injury', not 'unlikely to cause negative side effects', but you couldn't win every battle.
She was also one of the few people Sweep could count on for alchemical supplies – known by the laypeople as chemistry. That, and her extensive knowledge of the sciences did come in handy when she was performing her various witch-related activities.
...granted, the flying broom she'd given her threw her face-first into a wall, but one didn't become a witch overnight. Practice made perfect after all.
Shaking off the memory Sweep held the box of chemicals to her chest, ignoring the fragrant acidic scents they wafted as she made her way down the corridor. At this time of evening it was completely deserted, the lights all turned off in the classrooms and the corridor lights dimmed to save on power, leaving it feeling rather spooky. Yet she remained largely unaffected, too busy squinting at the door names and remembering where Tachyon invited her to to really care about the spookiness.
Until soon she found her destination; Chemistry Lab 6. Without bothering to knock she put her shoulder to the door and bent the handle with her elbow, grunting as she pushed the door open – revealing a dimly-lit lab, only a single light on near the centre of the room. More prominently, however, was the bright pink glow that radiated throughout the room, so bright she had to avert her eyes lest she be blinded by it.
''T-Tachyon?'' Sweep called out, grunting as she hefted her chemicals up onto an empty table. ''I brought your stuff.''
''Hm? Oh Sweep, why thank you~'' Tachyon called out, the pink glow finally dimming.
Allowing Sweep to see the brunette scientist tinkering with a beaker and a vial full of radiant pink liquid. The bright glow waned as she took it off the heat and picked the vial up between some tongs, dipping it into a prepared bucket of water and releasing a potent hiss of steam. It rippled up towards the ceiling and cast an ominous shadow against the back wall, which coupled with Tachyon's giggling silhouette made for an ominous image.
Far too curious now Sweep drew closer. ''What's that?''
''This-'' Tachyon hoisted the vial high – its glow dimmed, but its hot pink colour as bright as ever, ''-is a love potion.''
''...eh?'' Sweep blinked, then her eyes widened. ''W-Wait, like a real love potion?!''
''Mmhm~ Guinea Pig-kun is still so indecisive about his feelings, so I decided to try and give him a little nudge.'' Tachyon sighed. ''Alas, each dose seems to be ineffective on humans. Thus I'm refining the formula for now; this is just a test batch.''
''T-Test batch, huh.'' Sweep fidgeted, her heartbeat quickening. ''Does that mean you're gonna just t-throw it away?''
''Indeed. I am capable of safe disposal, you know.''
Sweep nodded, yet her mind was elsewhere. A love potion. A genuine, bonafide love potion – because if anyone could make one it would be the genius Tachyon. Even if there was a good chance it wouldn't work just the possibility of it doing what it was designed to do...
''C-Can I have it?!''
''Hm?'' Tachyon looked over her shoulder at her, curious. ''I suppose you could take it, it's of no use to me now – just remember to bring the vial back afterwards, it's school property after all.''
Sweep stammered out an agreement, holding her hands out reverently and closing her fingers around the pink vial, the glass still slightly warm to the touch. The pink liquid within sloshed and the faint fragrance of raspberries tickled her nose, potent enough to make her shudder, but she resisted the urge to take a sniff. This vial was for one person only, and she didn't want to risk wasting a drop.
''Oh I forgot to mention it's quite potent.'' Tachyon drawled lightly, already flipping through her notebook. ''Should kick in within moments of ingestion. Also if you plan on using it on another, then be sure to adjust the amount-''
The sharp thud of the door informed her that Sweep was no longer listening, and had already fled the room.
Tachyon sighed, shaking her head, but returned to her work without issue.
'Now... maybe a blueberry flavour would improve its seductive effects, Guinea Pig does enjoy them the most, fufu~'
X-x-X
It was a nerve-wracking experience crossing campus with a vial of very suspicious pink liquid.
She wasn't too concerned about being seen, she knew she'd done weirder things in front of the student body, but he risk of Tazuna finding her and confiscating her newfound potion made her heart thump against her chest. The only mercy was that at this time of day much of the student body was either heading to the cafeteria or out training while they still had daylight to work with, meaning she faced few interruptions on her trip back to the dormitory.
It also meant that the dorm was much less populated, with only a couple dozen people around – none of whom noticed the vial she hid behind her back. With the vial in hand she made her way up to the third floor where her Kitasan's dormitory was, knowing she'd be in at this time of day and that Diamond would be out, if only for another half an hour. It wasn't much, but it might be enough time.
Thus when she reached the destined door she all but rammed her knuckles against it. ''K-Kitasan! Open up!''
''Huwah?! S-Sweep-san?!'' Came a startled yelp from inside. ''H-Hold on a second...!''
With considerable effort Sweep did; containing her jittery excitement as best one could given the situation. Small mercies nobody else was in the corridor to sneak up on her because right now her utmost focus was on the door, anticipation welling within her stomach as she heard footsteps draw near – when with a click the door opened, swinging inwards to reveal a flustered Kitasan Black.
''Sweep-san, what's the matter-''
Sweep wasted no time in shoving the vial in her face. ''Quick, taste this!''
''Huh? This is...?''
Words formed on Sweep's lips only to perish just as fast – her heart skipping a beat as she very nearly admitted what the potion was. Because if Kitasan knew then surely she wouldn't consume it. Telling her to drink something without telling her what it was did ignite a spark of guilt in her gut but she pushed it down as fast as it formed, her eagerness to see the potion work outweighing her shame.
''J-Just drink it! It's safe, I promise!'' And goddess above did she hope it was, otherwise Kitasan would be mad at her, not Tachyon.
Kitasan blinked, more befuddled than uneasy as she lifted the vial of luminous pink liquid – and with a shrug, brought it to her lips.
Sweep tensed, hands to her chest as she watched the liquid leave the rim of the glass vial, as it disappeared over Kitasan's plump bottom lip, a trio of glugs ringing out before she tilted the vial back – leaving just under half of the fluid left. She wiped her chin dry of liquid and made a face like she wasn't sure whether to like or dislike the flavour, then tilted her head, a slight hum escaping her.
''It tastes...'' Kitasan smiled, ''...kinda nice actually. Did you make this?''
''Uh...'' Think think think, ''Yes?''
Kitasan giggled. ''I wouldn't mind drinking more of it in future if you decide to make some. Maybe even Tazuna-san would let you sell it in the cafeteria!''
Sweep jerked her head in a nod, her eyes flitting to Kitasan's lips. ''D-Do you feel any different?''
''Hm...'' She shut her eyes, thought – then grinned. ''Nope! I'm as right as rain.''
And just like that, her grand plan was foiled.
''Ehh?! I-It didn't work?!'' Sweep stomped her foot. ''N-No way! Don't tell me it came out defective?!''
Kitasan smiled sheepishly, an awkward laugh leaving her lips – only to yelp as Sweep swiped the vial back with a growl and, infuriated with the 'defective product', chugged the remaining half of the liquid to test why it wasn't working. Overlooking a rather crucial detail in her moment of frustration.
She had a much lower weight than Kitasan, and thus a much lower tolerance to substances.
A detail Sweep intimately realised as she felt warmth spread down her throat and through her belly, the sensation tingly and almost pleasant – only to then fan into a scorching, crawling fire that sent a quiver through her belly and further south. Faster than she thought possible the warmth spread along her arms and down her legs, reaching her toes and fingers with liquid heat and then rebounded back up to her core, quickening her heartbeat with the flood of tingling heat.
Her lips parted but no words escaped – her gaze locked onto Kitasan's own smooth, slightly-plump lips, naturally pronounced and so very kissable. No self-consciousness rose to stop the desire and with the heat rushing through her body she felt unshackled for once in her life, the thought of restraining herself an alien, useless desire; one she cast away physically as she stepped closer, putting herself in Kitasan's personal space. The black-haired Uma stepped back on instinct but Sweep inched closer in response, both of them venturing step by step into Kitasan's room until Sweep could push the door shut behind herself, much to Kitasan's flusterment.
''S-Sweep-san, are you- mmph?!''
With an assertiveness Sweep previously lacked she caught Kitasan by the collar and dragged her down to her level, mashing her lips against the taller girl's in a kiss. Kitasan froze solid, nary a squeak leaving her throat as Sweep devoured her voice, the contours of her friend's lips enchanting her for a dangerous moment – and with some measure of meekness Kitasan reciprocated, shy and confused but unwilling to be a statue in this situation.
Then all too soon the kiss ended as Sweep Tosho pulled back, panting and flushed. Her witch hat was tilted back and left nothing to hide the sheer want in her purple eyes, her hands shifting down to Kitasan's arms and holding them tight, refusing to let her get away, not that Kitasan had any intent on fleeing.
''Sweep-san, do you...?''
''Duh!'' Sweep pouted, glaring up at the dark-haired girl. ''You're the only one in the whole world who is allowed to date a witch-in-training such as myself. T-Therefore, you're not allowed to refuse, or... or I'll cast a spell on you!''
''Looks like I don't have a choice, huh...'' Despite her words Kitasan smiled fondly, slipping her hands down into Sweep's own – igniting a fiery blush across the petite Uma's cheeks. ''You know you can't take this back later, right?''
''Obviously!'' Sweep stomped her foot and dipped her chin. ''S-So um... can I have another kiss?''
Kitasan giggled, the elation in her voice tempered into something sweeter, something kinder. A kindness Sweep got to feel as her cheeks were cupped, her head was tilted back – and Kitasan pressed their lips together in a deep, romantic kiss. Sweep utterly melted into it, a moan of delight escaping her and wrapping her arms around Kitasan's waist, pulling her lover closer as she lost herself in the moment.
Yet she wanted more. Even as she deepened the kiss her hands wandered up Kitasan's side, feeling her up in a way she would never normally be bold enough to do so. Kitasan answered only with a light hum, making no move to stop her – and in a fit of need, jealousy and potion-induced mania, she grabbed her tits.
''Ah~'' Kitasan flushed as she pulled back from the kiss. ''Sweep-san-''
''No fair, how are yours so heckin' huge...'' Sweep grumbled, sinking her fingers in and feeling the bra cups beneath. ''I want big boobs too...''
Kitasan smiled slightly; a breathy exhale leaving her as Sweep groped her so roughly, the touch oddly stimulating. Catching the witch's chin she lured her back up into a kiss but didn't stop her wandering hands, gladly losing herself in the kiss even as Sweep filled her palms with her chest. The moment they broke off the kiss Sweep shifted her hands down to her waist and gave her a slight push, sending Kitasan stumbling a step back and landing on her bed with a yelp.
No more than a half-formed syllable left her lips before Sweep straddled her, darkening Kitasan's cheeks – and a hungry, eager kiss devoured her moan as she let herself be pushed flat against the quilt. Domineering despite her small size Sweep pushed her tongue against her teeth; said teeth parting without protest and allowing Sweep to invade her mouth, their tongues tangling in a clumsy, inexperienced mess that nonetheless fuelled the rising eroticism of the moment.
''Myn, Sweep-san...'' Kitasan breathed as their lips parted, their breaths intermingling between their mouths. ''Isn't this a little fast...? Shouldn't we slow down a bit...?'
''Ya~da~'' Sweep drew the word out, and Kitasan shivered as Sweep ran her hands up her shirt. ''I waited super long for this, my heart can't wait any longer.''
''Well... I-I guess it's okay, then...'' Demurely Kitasan conceded, a slight smile coming to her lips. ''But... only if you tell me your feelings out loud.''
''H-Huh?! Why?!''
''Because I wanna hear them.'' Gently Kitasan sat up, leaving Sweep straddling her lap.
A position Sweep was all too aware of, her eyes flitting down to Kitasan's chest enviously before returning to her enchanting red eyes, only to avert her own. Even with the potion swimming in her system embarrassment still crept up her throat, threatening to swallow the confession mounting within – but the potion, ultimately, helped coax the truth from her lips.
''I-I... love you...''
''Hm? What was that?''
''I love you okay?!'' Sweep's near-shriek made Kitasan jump, then flush crimson. ''T-There... I said it.''
''...hehe. You really are sweet, huh?'' Kitasan smiled warmly. ''Truth be told I've liked you for a while too, Sweep-san. Knowing you feel the same makes me happy~''
The knowledge that Kitasan not only didn't reject her but reciprocated her feelings, combined with the love potion pumping through her system – it melted what remained of Sweep's self-restraint. Resulting in her darting in and mashing her lips against Kitasan's own, devouring her surprised mewl as she poured her feelings into the kiss. Kitasan responded in kind, hands on her hips then shifting lower, holding her thighs as Sweep's own hands dipped lower, skirting the edges of her shirt.
Kitasan giggled faintly as she pulled back from the kiss, her shyness outmatched by her gentle affection. ''Want me to take it off?''
''Uh, p-please...''
Stifling her smile Kitasan leaned back slightly, loosening the ribbon on her academy serafuku top before hauling it up and over her head; exposing her toned tummy, her slender waist, and most pointedly her ample bust contained within a black sports bra. The latter of which utterly captivated Sweep's attention, her eyes glued to Kitasan's cleavage even as the Uma herself shed her top with a sigh of content, topless aside from her bra.
Noticing Sweep's undivided attention Kitasan felt her cheeks darken and reached behind her back – but, before she could hook her fingers under her bra, an idea came to her mind. One slightly cheeky, but one that felt fair given the circumstances.
''Want me to take this off too?''
''Immensely...'' Sweep breathed, sounding nearly hypnotised by the idea.
Bringing a small, wry smile to Kitasan's lips. ''Fine... but if you wanna, then you'll have to take something off too~''
It felt dangerously flirtatious, but the reaction was everything she hoped – a squeak, a blush, and a sudden clarity in Sweep's eyes. Clarity that boiled away into embarrassment then reduced to thick, simmering want so potent it made her stomach feel hot just seeing it. Barely a second later though Sweep complied, unzipping her skirt and pushing it off with haste, revealing the purplish, lavender-coloured panties that hugged her narrow hips.
Kitasan soaked in the sight, swallowing the lump in her throat even as she followed up on her end of the deal – her fingers curling, tugging, then ultimately pulling her bra up and over her head. She had barely gotten it over her head before Sweep's hands were on her breasts; fingers sinking in greedily and kneading her breasts like she'd been waiting to for years, the enthusiasm jolting a weak moan out of Kitasan herself.
A flick of her wrist sent her bra to the bed and let her arms settle on Sweep's bare thighs, noting how slender they were compared to her own – a detail that became secondary as Sweep suddenly bent down low and took her left breast into her mouth. Hungrily she suckled on her nipple, lips sliding across flesh until she caught it between her teeth and tugged it out; letting it rebound back against her breast and eliciting a mewl from Kitasan herself.
''Sweep-san~'' Breathily Kitasan mewled her name, running her hands around to the petite Uma's ass, caressing it. ''You're really focused on my chest, huh...''
Sweep's face bloomed red at being called out, yet rather than deny she responded by burying her face in Kitasan's chest, all but motor-boating the bustier Uma and sending them flopping back onto the bed. The witch hat rolled off to one side but for once Sweep didn't fret over parting with her hat; instead with panting breaths she pressed her face into Kitasan's belly, whimpering with carnal need as she nuzzled her toned flesh and felt her belly against her cheek, the contact arousing in ways she couldn't name.
For both of them. Kitasan bit back the shy moan that threatened to escape and instead ran her fingers through Sweep's brown hair, caressing her head and further eliciting whimpers from the witch-in-training. Sweep sat up slightly as a result, her laboured breaths combining with her lidded gaze to paint the image of a girl in heat, her whole body trembling with anticipation, with need, with want.
A want Sweep demonstrated as she grasped Kitasan's left leg, lifting it enough to slip her own leg beneath – and Kitasan's face bloomed scarlet as she realised what Sweep had in mind. Any thought of protest though perished as soon as it came, a whimper of need bubbling up her throat as Sweep's clothed cunt brushed against her own, their underwear grinding together in a hurried, clumsy motion that nonetheless made both of them quake.
''A-Ahh...'' Sweep trembled and did it again. ''K-Kitasan~''
Kitasan answered only with a shy mewl; clutching at the quilt and tensing as Sweep rocked her hips again, scissoring up against her with open need. Clutching at her skirt she hiked it up and trembled as their loins met more intimately, only their underwear between them as Sweep grinded against her – short, hurried rocks of her hips tempting Kitasan to do the same, inexperienced but increasingly horny as she met Sweep's loins with her own.
The fact that Sweep was the one dominating her despite being physically smaller only fed her burning-red blush, a whine escaping the black-haired Uma as she gripped the quilt and put her hips to work, unwilling to be entirely submissive. Their movements were jerky but by the second they found a sort of rhythm to it, their clothed loins grinding together and sending sparks of pleasure rushing through them both, their moans nigh-synchronised.
''Feels... s-so good...!'' Sweep managed to get out, eyes tightly shut as she moaned.
Kitasan agreed, though didn't dare voice it lest an embarrassing sound replace her words – settling for a jerky nod as she eased backwards, her quaking arms unable to support her and sending her flopping onto her back. Sweep pounced like a predator before prey, sitting up and lifting Kitasan's left leg high before taking charge; sweep, stuttering mewls tumbling from her lips as she rubbed her crotch against her lover's own, their underwear dampened by excitement and adding extra friction to the moment.
Excitement that only bloomed hotter in Sweep as she soaked in Kitasan's half-naked form. Her tummy drew taut as their clothed pussies grinded against one another, her plump breasts heaved with her gasping breaths, her smooth shoulders tensed and flexed as her back arched away from the bed. Her face bloomed scarlet and her lips pursed in a futile attempt to keep her voice down, whimpers and whines escaping despite her best efforts, her lips ultimately parting to emphasise their plumpness.
Sweep quivered at the sight, her aching loins begging for more – and so she gave more. Gripping onto her lover's raised thigh she rocked her hips like an Uma in heat, scissoring with her beloved and extracting whines from her lungs. Friction sparked across her core and fuelled the flames burning within, the fire swelling into something bigger and tighter, a knot in her groin that she refused to loosen as she grinded madly against Kitasan.
''A-Ahn, if you- mmn, k-keep doing that...!'' Kitasan's voice wobbled dangerously close to a cry.
The sound only hastened her movements, desperation mixing with imminent climax and narrowing her vision, nothing but pleasure and Kitasan on her mind. The risk of being overheard was entirely absent from her mind as she whined, bucking and rolling her hips frantically, every ounce of friction edging her that much closer to orgasm, her thighs quaking with the thought and her stomach caving in with her ragged breaths.
When Kitasan cried out; the sound mottled by her hand but bleating out all the same, her lower half buckling as she orgasmed – and Sweep came. Whether from timing, the sight, or the knowledge she had made her lover orgasm; it instantly shot Sweep over the edge and made her orgasm. Her voice caught in her throat and she convulsed as white-hot pleasure seized through her muscles, her mind devoid of thought and hips frantically bucking her up against Kitasan's own, gushing and soaking her underwear with her elation.
Then all too soon their orgasms shuddered, drawing to a close. Sweep whined and leaned back, her arms like jelly-
Only to yelp as she fell over the edge of the bed, landing with an undignified grunt – then embarrassed, defeated groan.
From her spot on the bed Kitasan giggled, pushing herself up with quaking limbs and crawling the short few paces forwards, allowing her to look down at Sweep as she laid with her upper back to the floor and legs awkwardly above herself, nearly folding from the position.
A position that also left her crotch within easy view, her ruffled purple panties damp and tucked slightly to the side, exposing a hint of pussy beneath. The temptuous view instantly reignited the heat in her loins, tempting her fingers around the crotch of Sweep's panties and pulling them to one side, laying bare the smooth, puffy lips of her lover; gleaming with her excitement with a slip of pink poking out between.
Kitasan smiled mischievously. ''Itadakimasu~''
''H-Huh? What're you- mmyah~!''
Without a shred of shame Kitasan went down on her, putting her tongue to work and reducing Sweep to a squealing mess on the floor – her upside-down position rendering her helpless to resist the oral assault. Thumbs tucked themselves against Sweep's folds and spread her pussy for easier access, allowing Kitasan to press her tongue into Sweep's quivering entrance, licking it with an enthusiasm that left the witch squealing.
A sound Kitasan found herself loving; her belly hot and face hotter as she drew her tongue along Sweep's honeypot, tasting her excitement and lapping it up like it was the first drink she'd had in weeks. It didn't hurt as well that, upside-down as Sweep was, her serafuku top sagged down to expose the lavender sports bra hugging her flat chest. Had her hands been free she might've sent them wandering up her top, to palm and feel such a flat chest, to appreciate the contours of her lover more.
Instead she devoted herself to eating her out; any embarrassment secondary to the delight coursing through her heart at every moan Sweep let out, the sounds whimpering and weak as she used her tongue mercilessly. Soon she couldn't keep her hands still and sent them wandering across Sweep's thighs, groping and kneading her slim but soft legs and squeezing even more cute noises out of her lover.
''Hehe... you're so cute, Sweep-san~'' Kitasan cooed into her pussy.
Right before going back to eating her out.
Sweep cried out at that, legs jerking stiff but unable – or unwilling – to free herself from the position she found herself in. Excitement pooled in her tummy and the position only added to the weight of it, every breath laboured and inhaling rendered harder with Kitasan's tongue lapping at her cunt, every lick electric and jolting the sense out of her mind, leaving her hands futilely clutching at the carpet.
It didn't help that the position made all the blood rush to her head, the sensation only making the pleasure feel that much more intense – her post-orgasm sensitivity making it doubly worse. Try as she might Kitasan's tongue was dangerously good, licking and flicking in ways Sweep didn't think possible, her lower half spasming and buckling from the increasingly-earnest licks that sapped reason and logic from her mind.
''A-Ahh, no, it's... I-I really will...!''
Muscles tensed, fists clenched, breaths bundled in her throat. She endured, tightly coiled like a spring even as Kitasan lapped at her pussy, teasing her with nothing but her tongue-!
Until that tongue flicked her clit, and Sweep came hard.
By some miracle her voice cracked, cutting her scream into a wheezing exhale of euphoria – her stomach taut as her back arched, her heels digging into the bed, her eyes rolling back. All whilst Kitasan voraciously ate her out, giggling as she tongue-fucked her into squirting; her fingers coming down to grip Sweep's pert ass and holding her steady as she silently convulsed beneath her.
Then all too soon her orgasm waned, and gravity took took – sending Sweep falling over herself with a low moan, her head down and ass stuck up in the air.
A view Kitasan enjoyed, giggling sweetly as she shuffled to the edge of the bed and wiped her face dry with her discarded shirt.
''Hey, Sweep-san...''
Groaning Sweep lifted her head – only to freeze as she found Kitasan before her. Knees apart, skirt lifted, and damp black panties tucked to one side.
''Can you do me too...?''
…
Sweep would be between her thighs in moments, and Kitasan's sweet moans would soon fill the dorm room.
Unaware of an exasperated Satono Diamond waiting outside, pretending not to hear the details as she made sure nobody strayed close enough to overhear as well.
