AO3 | Masterlist
The scent of crushed herbs and simmering elixirs curled through the air, thick with magic and lingering heat from the flickering candlelight. You moved swiftly through your workshop, the sleeves of your robe pushed up to your elbows, hands busy grinding a handful of dried hibiscus petals into a fine powder. The pestle moved in slow, rhythmic circles, a familiar motion that should have been meditative but your mind wandered.
The cauldron in the centre of the room bubbled gently, its contents shimmering with an iridescent sheen. A single drop of the wrong ingredient could shift its purpose entirely, and yet, despite knowing this, you barely spared it a glance as you reached for a vial of honey-thick nectar resting beside you. You were distracted.
It wasn’t your fault, not really.
Not when two succubi shared your home, moving like sin incarnate through your space, leaving temptation in their wake as effortlessly as breathing. Agatha and Rio were creatures of hunger—lust woven into the very fabric of their existence—and while they spared you from their predatory nature, they did nothing to temper the pull of their presence.
And, as if conjured by your thoughts alone, Rio’s laughter drifted in from the other room.
It was a warm, low sound, filled with mischief, the kind of laugh that always meant trouble. You exhaled through your nose, setting the vial down with careful precision. Whatever she was up to, it was best not to get involved. Not when you were this close to finishing your work.
The love potion had been an afterthought—a test, an experiment, something to keep stored away for research rather than practical use. You had no intention of actually using it. Succubi had no need for artificial desire; their own abilities surpassed anything that could be brewed in a bottle. Still, curiosity had led you to concoct it, blending rare aphrodisiacs with dreamroot essence, a few drops of moon-kissed wine, and a dash of honeyed rose oil.
It was potent. Dangerously so.
And you should have tucked it away the moment you were done, sealed it within a warded chest where it could do no harm. But you hadn’t.
Instead, the vial sat unguarded amidst your collection of more harmless elixirs, the deep crimson liquid glistening under the candlelight. A temptation disguised as an innocent draught.
And, as fate would have it, Rio’s curiosity was as boundless as her appetite.
You didn’t notice when she entered, didn’t see the gleam of intrigue in her sharp golden eyes as she plucked the vial from its resting place. The moment your back was turned, she lifted it to inspect the contents, swirling the liquid idly.
It smelt… expensive. Rich. Decadent, like spiced fruit and something dangerously sweet. Her forked tongue flicked out, tasting the air, and her pupils dilated with interest.
This was new.
She liked new things.
Without a second thought, she slipped out of the workshop, the vial tucked between her fingers, her mind already racing with the possibilities.
—
Agatha was lounging in the sitting room when Rio found her, half-draped across the velvet couch, one arm resting lazily over the back. She looked every inch the predator she was, dark eyes hooded with a perpetual, knowing smirk tugging at the corner of her lips. She was dressed down, her usual structured coat abandoned in favour of her half-unbuttoned shirt and loose slacks. Her feet were bare, her hair still mussed from sleep, yet she exuded control.
Rio slid up beside her, draping herself over the armrest with casual ease. "Brought you something," she purred, twirling the bottle between her fingers before offering it up with a smug grin.
Agatha arched a brow, reaching for it without hesitation. "What’s this?"
"Something Y/N made," Rio hummed, watching as Agatha uncorked the vial. "Figured it’s one of their fancy elixirs. Thought you might like it."
Agatha inhaled slowly, rolling the scent over her tongue. There was something odd about it, but it wasn’t unpleasant. On the contrary, it smelt delicious. A rush of warmth tingled at the back of her throat, her body responding instinctively before she had even taken a sip.
Rio should have stopped her.
She could have stopped her.
But she didn’t.
She just watched as Agatha tipped the bottle back and swallowed it whole.
It hit her like wildfire.
One moment, Agatha was lounging with an air of effortless control, and the next, she was bolting upright, her spine going rigid, her pupils blown wide.
Heat. Unrelenting, all-consuming heat.
She sucked in a breath through her teeth, her claws digging into the upholstery as she gripped the edge of the cushion, bracing herself. The burn was instantaneous, roaring through her veins, pooling deep in her core.
What the fuck—
Her mind reeled, but her body knew exactly what it wanted.
She was starving.
It was wrong, unnatural. Succubi didn’t need help feeling desire—they were desire—and yet, whatever had been in that vial had amplified her hunger tenfold. Her tail flicked behind her restlessly, her breath coming short and sharp, and her fangs throbbed with the urge to sink into something soft, something pliant.
Rio blinked at her, watching as her typically controlled partner came undone in real-time. "Uh… Ags?"
Agatha snapped her gaze toward her, and Rio visibly stiffened.
Agatha was never desperate. She was the calm one, the controlled one, the one who always kept her hunger in check. But not now.
Now, her pupils were nothing but thin golden rings swallowed by black, her lips parted just enough to reveal the sharp gleam of her canines, her chest rising and falling far too quickly.
Rio’s fingers twitched involuntarily, her own body reacting to the shift in the air. Power, heat, and lust. The room was suddenly thick with it, suffocating, heavy enough to drown in.
And then, as if realising exactly what had happened, Agatha turned her head toward the workshop—toward you.
Her tongue darted out to wet her lips. "I need them," she growled, voice lower, rougher, her control already slipping.
Rio exhaled sharply, eyes widening. "Oh. Oh."
For the first time in centuries, she might have actually fucked up.
And you were about to find out just how badly.
—
You felt the air in the cottage thicken, charged with something potent—something unnatural. It slithered through the dimly lit space like invisible smoke, curling around you, settling into your lungs with every breath you took.
Something was wrong.
The magic in the walls whispered warnings, the candles flickering wildly in their holders despite the absence of a breeze. Your body reacted before your mind could catch up, an instinctual prickle at the back of your neck telling you that something powerful had been unleashed.
And then you felt two ravenous, predatory forces—one sharp and crackling like lightning, the other slow-burning and consuming like an ever-hungry fire. The tether between you thrummed, an invisible thread of magic stretched taut, vibrating with a heat that wasn’t entirely your own.
You turned just as Agatha stepped into the doorway.
Her composure—her usual air of effortless, knowing control—was shattered. What stood before you wasn’t the measured, cunning succubus who prided herself on restraint. No, this was something else entirely.
Her pupils were nothing but dark pools, golden irises reduced to thin, molten rings. Her breathing was slow and deliberate, like a creature struggling to leash itself, though every inhale seemed to make it worse. Her normally neat attire was in disarray, her shirt rumpled, collar askew as though she’d clawed at her own skin in a desperate attempt to cool herself down.
She looked starved.
A soft thud behind her signalled Rio’s arrival, and when your gaze flickered past Agatha, you found her in a similar state—if not worse.
Unlike Agatha, who was still barely clinging to her composure, Rio was already half-feral. Her lips were parted, sharper fangs glinting in the candlelight. Her tail lashed behind her, the spade-shaped tip curling, uncurling, betraying the sheer magnitude of her agitation.
And when she exhaled—you felt it.
A heat coiled low in your gut, winding itself around your ribs, pressing. It wasn’t meant to be for you, not directly—you were not prey, you were not a target—but their hunger had grown too wild, too untethered, and their instincts didn’t care for the technicalities.
Agatha’s fingers flexed at her sides, her knuckles nearly white with restraint. Barely leashed, barely holding on.
“Y/N.”
Your name came out low, more exhale than word, more prayer than plea.
And by the Divine Mother, that was dangerous because succubi didn’t beg. Succubi took.
Your pulse quickened, but not from fear. This wasn’t the carefully measured seduction you were used to. It wasn’t playful temptation—the slow game they so often relished—this was raw.
Primal.
Uncontrolled.
You swallowed hard, taking a slow, deliberate step toward them, and the reaction was instantaneous.
Rio’s breath hitched; she crossed and uncrossed her arms, as though trying to shield herself from the unbearable ache thrumming through her body. Agatha’s jaw clenched, her fingers twitching like she wanted to reach for you but knew she shouldn’t.
"Tell me what happened," you said, voice steady despite the way the energy licked at your skin, despite the way your own magic—so much weaker than theirs, so mortal—shuddered under the pressure of it.
Rio let out a breathless, shaky laugh, but it held none of her usual mirth. "Funny story," she muttered. "I may have… kind of… accidentally… given Agatha a potion."
You frowned, tilting your head. "What potion?"
Agatha’s nails dug into the doorframe, her chest rising and falling, every breath seeming to cost her something. "The one you left on your desk."
And just like that, realisation slammed into you.
The love potion.
The highly concentrated, dangerously potent love potion.
The one not meant for actual consumption—especially not by creatures who already thrived on desire.
Oh.
Oh, fuck.
Your stomach dropped, your breath hitching, not in fear but in sheer, undeniable understanding.
Succubi were designed to handle lust. It was their nature, their essence. But they were also designed to control it. To wield it rather than succumb to it.
This potion?
It had burnt through their natural restraints like kindling on an open flame.
And now they were left unsated, unable to quench the inferno no matter how hard they tried.
Agatha let out a harsh breath, her fingers twitching. "Y/N," she said again, and this time it was a warning.
Because she was so close to losing what little control she had left.
Because she was starving for something only you could give her.
You felt the pull, the same one that had always existed between you, the one that was usually tempered by their restraint but now burnt, raw and untethered. They needed you.
Not as prey.
Not as a conquest.
But as something else entirely.
And maybe, just maybe, you were more than willing to oblige.
Agatha’s breath hitched as her last thread of restraint snapped. In a blink, she was on you, pressing you down into the bed with a force that sent a shiver straight through your core. Her claws curled into the fabric around your wrists, pinning you in place as the heat of her radiated into your skin.
Her pupils were nothing but thin rings of gold, swallowed by the black hunger of her gaze. Her body shifted against you, the air rippling with raw, unfiltered magic as her succubus nature surfaced in full. Claws elongated, her fangs peeking past parted lips, the scent of heady desire thick between you.
Behind you, Rio slinked in with practiced ease, her body curving around yours as she caged you between them. You barely had time to gasp before she hooked her legs around yours, spreading them open effortlessly. Her voice was a molten whisper against your ear, her lips brushing over your skin as she chuckled.
“Fuck, I’ve never seen her like this before,” she murmured, her tail curling teasingly around your thigh. “You really should’ve kept that potion locked away, huh?”
Your pulse pounded against your ribs. There was no escape, no space to think or breathe, but you didn’t want to escape. Not when they were both so desperate, their need vibrating through every fibre of your being.
Agatha growled low, the sound vibrating through your bones as she leaned down, her lips ghosting over your throat. “I need you,” she rasped, a confession that sent heat pooling between your thighs.
Her magic surged, the air around her shimmering as she shape-shifted, the scent of pure, unfiltered want thickening. Your breath hitched as she ground against you—a new, unmistakable bulge in her slacks pressed firmly against your core. Even through the layers, the heat of it was overwhelming.
Rio let out an appreciative hum, her fingers trailing down your arms, tracing the shape of your body as she pressed teasing kisses along your shoulder. “Oh, she’s really gone,” she purred, voice thick with amusement. “You’ve made our dear Agatha completely lose control. I wonder what she’ll do to you.”
There was no teasing, no slow buildup. Agatha was too far gone for that. With a snarl, she made quick work of your clothing, her claws slicing through the fabric at your crotch, tearing it open without care. A strangled moan escaped you as the cool air met with your heated skin, but it was nothing compared to the heat of Agatha pressing flush against you, her hips rolling, grinding against your exposed core.
She exhaled shakily, her composure unravelling as she reached between you, unbuttoning her slacks, just enough to free herself, just enough to wrap a clawed hand around the thick, twitching cock she had conjured, her breath catching as she stroked herself once and then twice, a needy, desperate sound spilling from her lips at the sensation. Her lips parted, panting, utterly wrecked with hunger.
Rio’s fingers danced along your stomach, teasing, but she wasn’t cruel enough to delay things. She tilted your chin, brushing her lips over your ear. “She’s going to ruin you, love,” she whispered. “And you’re going to love every second of it.”
Then Rio groaned, pressing her forehead to the back of your neck, her fingers gripping your thighs as she rutted against you, the heat of her own need searing through layers of clothing.
“Fuck,” Agatha muttered, almost pained. “I can’t—I need—”
She cut herself off, lining herself up, swiping her tip through your arousal, groaning deep at the wet heat of you. The sensation sent a shiver through her entire frame, her claws digging into the mattress as she forced herself to savour it, to hold back even a fraction of her need.
Her body trembled with restraint she barely had. And then she gave in.
The first thrust was deep, a sharp stretch that had your back arching, a cry spilling from your lips as she filled you. Agatha moaned, a guttural, broken sound as she bottomed out, her forehead pressing against yours.
She started with slow, deep strokes, but it wasn’t long before the potion’s effects overrode any semblance of patience she had left. Her pace turned frenzied, hips pistoning into you with a force that had the bed rocking beneath you.
Rio held you steady, her tail coiling around your waist, her breath hot against your ear as she murmured sweet, filthy praises about how good you looked taking Agatha like this, how wrecked you sounded. She kept you grounded, kept you from unravelling too quickly—but even she couldn’t hold back forever.
The moment Agatha came, a strangled moan spilling from her lips as she shuddered against you, Rio let out a frustrated whine, her fingers tightening around your thighs.
“My turn,” she huffed.
Before you could catch your breath, they were moving you with supernatural ease, handling your body like you were made of nothing but air. You barely had time to register the shift before you found yourself straddling Rio’s face, her forked tongue flicking out in anticipation, her golden eyes blown wide with lust as she watched you hover mere inches away.
Your fingers instinctively wrapped around her horns, gripping them for balance—and the moment you did, Rio gasped, her eyes fluttering shut, a whimper escaping her lips as pleasure visibly shot through her. Her tail curled, body arching, her sensitivity betrayed in that single moment of weakness.
Agatha, ever the dominant one, took advantage of your distraction. She positioned herself behind you, pressing her front against your back, her lips ghosting over your shoulder as she reached around, her hands skimming your body. A slow, satisfied hum vibrated through her chest as she traced idle patterns over your sweat-damp skin, her touch both possessive and reverent.
“No one else gets to experience us in this way,” she whispered, her voice dark and edged with something dangerously close to obsession. “You don’t understand how rare this is, do you?” Her sharp teeth grazed the shell of your ear, her breath hot against your skin. “Creatures like us... we don’t get to be unrestrained without consequence. We take. We consume. We drain. We ruin.” Her fingers tightened against your hips. “But you? You survive us. You endure. You take everything we give, and you still breathe.”
She exhaled slowly, pressing a lingering kiss to your pulse, savouring the rapid flutter beneath her lips. “That makes you ours.”
The words sent a fresh wave of arousal coursing through you, and as if sensing it, Rio let out a pleased hum. Then, without warning, she pulled you down onto her mouth, her tongue immediately lapping at you.
A strangled moan escaped you, your grip on Rio’s horns tightening involuntarily. She let out a shuddering breath against you, her entire body tensing before melting into the mattress again. Her fingers dug into your thighs, firm but reverent, keeping you open for her as she dragged her forked tongue in slow, languid strokes, savouring every reaction she pulled from you.
“Fuck,” Rio groaned, voice muffled against your skin. “You—ngh, you really know how to handle me, huh? Holding my horns like that—” She cut herself off with a needy whimper, the sound sending a fresh wave of heat through you. “Fuck, I could keep you here forever.”
The pleasure was dizzying, an intoxicating blend of firm pressure and teasing flicks that left your nerves singing. Your thighs trembled as you rocked against her, seeking more, losing yourself in the sensation. Every brush of her tongue sent another spark shooting up your spine, winding the coil in your stomach impossibly tight.
Another broken moan spilled from your lips as Rio groaned beneath you, her grip on your hips flexing as she pulled you down harder, determined to make you fall apart completely. Your body trembled, your mind lost in the haze of their touch, of the way they surrounded you, overwhelmed you, worshipped you with a greedy mouth and hands that refused to let you go.
“More,” Rio demanded against you, her voice husky, pleading. “I need more.”
That coil in your stomach twisted impossibly tight, and then—it snapped. Your orgasm tore through you in a dizzying rush, your whole body tensing, back arching as a strangled cry escaped you. The pleasure surged like a storm, white-hot and overwhelming, leaving you shaking in its wake. But Rio didn't stop.
She moaned into you, the vibrations sending aftershocks coursing through your oversensitive nerves. Her tongue lapped at you, relentless, as if she had no intention of letting you come down from the high she'd just wrenched from you. Your thighs trembled, your grip on her horns tightening, half to ground yourself, half in a desperate attempt to push away from the unbearable pleasure.
"Rio—" Your voice came out broken, breathless, but she only growled in response, her fingers digging into your hips to keep you where she wanted. "N-No, I—"
"Yes," Rio murmured, her voice dripping with hunger. "You're not done. I can feel it." She dragged her forked tongue over you again slowly, letting you feel every agonising flick. "You can take it."
Your body jolted at the sensation, torn between oversensitivity and the maddening need she kept feeding. There was no escape—just the sensation of her mouth, the overwhelming heat, the slick slide of her tongue as she worked you open again, coaxing another wave of arousal from you before you even had the chance to recover.
For a while, Agatha seemed content to watch, her hands roaming your body, her claws teasing the sensitive spots she had memorised. But her restraint was never meant to last.
"You’re cruel, Rio," she mused, her voice sultry but laced with impatience. "Making them beg without even using words."
Her fingers slid up your torso, tracing every shiver, every twitch, until they wrapped around your throat in a firm, possessive hold. She didn’t squeeze—just held you there, reminded you of who had you, who was unravelling you so thoroughly.
"But if you’re going to ruin them," Agatha purred, her other hand sliding lower, "then I might as well help."
Soon enough, she was lining herself up once more, her magic cock pressing against your entrance once more, sending a shiver down your spine.
“I can’t wait any longer,” she whispered, her voice strained. “I need to be inside you again.”
She thrust in, and the sensation of both of them at once shattered the last of your composure. A desperate, keening cry tore from your throat, your body quivering, helpless between them. Every nerve burnt, every inch of you claimed, stretched, overwhelmed in the most intoxicating way.
Agatha’s pace was relentless, deep, and hungry, the force of her movements driving you further into Rio’s mouth, into the wet heat that refused to let up. Each thrust rocked you forward, pressing your clit against Rio’s eager tongue, her forked tip lapping at you with an unholy precision.
The room was filled with the sounds of slick heat, muffled cries, and the guttural groans of the two succubi chasing their pleasure. Agatha cursed breathlessly, the magic in her voice thick with desperation as she ground into you, hips snapping with a bruising force.
"So perfect," she murmured, her breath ragged against your ear. "Taking us both like you were made for it."
Rio moaned in agreement beneath you, the vibrations sparking another wave of pleasure that made your muscles seize. Your fingers tangled tighter in her horns, a lifeline against the dizzying sensations, and the sharp gasp that left her lips told you just how much she felt it.
"Fuck," Rio whimpered, the sound muffled, desperate. Her nails dug into your thighs as she rocked her hips against Agatha’s thigh, chasing her own pleasure even as she focused on yours.
Agatha smirked, her control fracturing as she felt the desperate rutting against her leg. "I see you’re just as needy," she taunted, pressing her thigh harder between Rio’s legs, feeling the heat there.
Rio’s whine was high-pitched and desperate, her tongue flicking against your most sensitive spot as she sought her own high. Her thighs trembled, grinding shamelessly, her pleasure tipping over the edge as you tugged on her horns again, sending another sharp jolt of sensation through her. She tensed beneath you, crying out, her body shuddering as she climaxed.
The sensation of her moaning against you, the slick drag of Agatha pounding into you, the heat, the sounds—it was too much. Your own release crashed over you, a blinding, shattering thing that left you breathless, your body shaking violently between them.
Agatha wasn’t far behind. A strangled groan escaped her lips, her hands gripping your waist with bruising force as she buried herself deep, her body shuddering through the force of her release. She pressed you down harder against Rio, grinding through the final aftershocks, her breath hot against your skin.
For a moment, there was only heavy breathing, the scent of sweat and sex thick in the air, the three of you tangled together in a mess of limbs, pleasure, and exhaustion. But their nature and the potion’s hold were unrelenting. No matter how many times they came, the hunger didn’t abate.
They kept going, over and over, their bodies moving in sync, driven by a primal need that refused to fade. You were lost between them, overstimulated, and overwhelmed, but you couldn’t bring yourself to stop.
—
Agatha was relentless, her thrusts growing erratic as she chased another orgasm, every snap of her hips sending shockwaves through your exhausted body. Rio, still buried between your thighs, never faltered, her tongue working you open, dragging pleasure from you even as your body trembled violently from the sheer force of it all.
You sobbed out their names, hands weakly clutching at Rio’s horns, thighs trembling against her cheeks. Agatha groaned above you, her grip bruising as she forced you down onto Rio’s mouth, her climax barreling through her with a raw, unfiltered intensity. She cursed, hips stuttering, her body shuddering against yours, as she came inside you yet again.
The sensation of Agatha’s cum dripping out of your overfilled cunt onto her chin sent Rio over the edge, her moan vibrating through you, her hips jerking as she rutted against Agatha’s thigh one last time. But it was the final stroke against your already wrecked bundle of nerves, the last push, that shattered you entirely.
A scream tore from your throat as pleasure consumed you—so intense, so overwhelming that your body seized, every muscle locking up before your climax hit like a tidal wave. The evidence of your orgasm drenched Rio’s face, spilling down her chin and onto the collar of her still-clothed chest.
Rio let out a shuddering sigh, her tongue sweeping over her lips as if she refused to let a single drop go to waste. Agatha, still draped over you, exhaled deeply, her grip on your hips finally loosening as the last tremors of pleasure faded into a slow, throbbing aftershock. The heat that had consumed all three of you had finally begun to ebb, leaving behind nothing but the weight of exhaustion and the sticky, intoxicating remnants of what had transpired.
The only sounds that remained were the slow, laboured breaths of the three tangled bodies lying amidst the wreckage of their lust. The fire that had burnt so violently through Agatha and Rio had finally dimmed, leaving behind the languid, syrupy pleasure of satisfaction.
Agatha, ever the controlled one, had collapsed first. She lay half-draped over you, her bare skin fever-warm, her breath ghosting over your throat as she pressed against you with a weight that was possessive, grounding. Even in her exhaustion, her arms caged you in, a silent claim, as if making sure you wouldn’t slip away.
She exhaled a slow, satisfied breath, but the moment was short-lived.
“You,” she rasped, tilting her head just enough to glare at Rio through heavy-lidded eyes, “are a menace.”
Rio, sprawled beside you, utterly wrecked but still smug as sin, let out a breathless chuckle. “C’mon, Ags,” she purred, voice raw from use, her tail flicking lazily against your leg. “You can’t tell me you didn’t enjoy yourself.”
Agatha huffed, pressing her face into the crook of your neck. “That is not the point.”
You, still trembling, mind fogged from overwhelming pleasure, groaned softly. “I am never leaving a love potion unattended again.”
Rio, ever the troublemaker, grinned. “Oh, sweetheart,” she murmured, propping herself up on one elbow to trace lazy fingers down your sweat-slicked skin. “I don’t know... You took both of us so well. Maybe we should make this a regular thing.”
You managed a weak glare, but it lacked any real venom. “Absolutely not.”
But Agatha and Rio exchanged a glance above you, something conspiratorial in the flick of their golden eyes, the curl of their lips.
Oh, they were definitely going to make sure this happened again.
-----
yeah that's right, I made their horns sensitive (I came very close to having Rio be able to cum just from Reader holding on to them but I added thigh grinding because it's hot :P)
