“How did you learn to do this?” Lumine asks Mona, staring at the long, swirling tendrils of water currently wrapping themselves around her wrists. The sensation is odd; it isn’t wet or cold, but more of a pleasant coolness, like a water slime without… well, the slime. The tendrils are oddly malleable, too; they’re solid as they wrap around Lumine, but they move in sync with her as she bends her arms and twists her wrists, pliant like clay. Lumine has never seen anything like it in her life. “Actually, how do they even form?”
“Ah - admittedly, I might’ve skimmed over that part, though I think they pull water from the air to form. I found the technique in this odd little spellbook I ordered from Fontaine,” Mona says, watching Lumine with intrigue as she flicks her fingers, manipulating the tendrils of water curling around Lumine with ease. The tendrils form from a peculiar, small swirling hole hovering close by Mona, who pays it absolutely no mind. “It’s quite strange, isn’t it? Of course, it wasn’t particularly difficult for me to acquaint myself with the intricacies of how the spell works, though I suppose I could always benefit from a little more practice.”
Lumine hums, tentatively poking at a tendril. The texture is strangely squishy, pillowing Lumine’s finger as she prods at it, and she makes a noise of amusement. “I think you’re doing well at using it,” Lumine tells Mona, glancing up at her. The way Mona is looking at her, intense with focus, makes her flush a little, and she fights the urge to look away as the astrologist watches her. “It doesn’t hurt at all, and I can see how easy it is for you to control it. Plus, I’m sure you’ll master it quickly after using it a few times in battle.”
At that, Mona clears her throat, glancing away from Lumine for a moment. When she looks back, her cheeks are the faintest shade of pink. “Ah,” she says, and Lumine glances back down at the tendril of water circling her wrist. The water is churning faster, and tiny splashes of sparkling liquid fly into the air. “Actually, I didn’t learn this entirely for the sake of battle. There were rather a few, um… personal reasons to help motivate me, actually.”
Lumine stares blankly at Mona, confusion evident on her face. “Personal reasons?” she asks, watching as Mona’s face progressively turns pinker. “Does it relate to astrology somehow?” Lumine peers back down at the water circling her wrist. As pretty as it is, glittering and catching the light as it moves, she doesn’t quite see how Mona could possibly reflect the stars in these odd coils of water.
When Lumine looks back up, Mona is positively glowing with embarrassment. “I - ah, not quite,” she admits, speaking through gritted teeth. “How would I even manage to see anything with - ugh, never mind. Personal reasons, Lumine.”
Lumine stares blankly. Mona stares back, her face flushing red. The water churns faster, and more crystalline drops of water fly into the air.
“I’m not sure I understand,” Lumine says, sheepish.
Mona huffs out an exasperated sigh, and with a sudden twinkle of stars, the tendrils of water curled around Lumine’s arms disappear into thin air. “Archons, Lumine! I realise that you hail from some other world, but surely you must know,” she grouches, moving across her room with a dramatic flutter of her cape until she’s standing in front of her cluttered desk. She moves thick astrological tomes and instruments made of crystalline glass and gold around until she finds a relatively battered little book somewhere among the pile, hidden conspicuously under a large globe covered in glittering stars and constellations. “Here,” she says, crossing the room and thrusting the book at Lumine. Lumine notices Mona isn’t quite catching her eyes, pinker in the cheeks than ever, and carefully takes the book from her hands.
Lumine can’t quite make out the text on the front cover with how battered it is, but she’s certain she can make out something along the lines of magical techniques and pleasure and alone in some archaic language. After glancing at Mona, who is still very carefully avoiding looking at Lumine by staring rather intensely at the blank wall to their left, Lumine opens the book, choosing a page that seems to have been dogeared already by Mona herself.
The page she lands on is enough to immediately clue her in on exactly what it is that Mona is talking about.
“Oh,” Lumine says, peering at the pages of the book with wide eyes. There’s an elaborate depiction of a nude woman using the very same water tentacles wrapped around Lumine's arms in ways that Lumine certainly won’t be forgetting any time soon. In fact, the image itself seems to be the main focus of the book - the spell is written under it in a font so small Lumine has to squint to read it properly. “Um, I see. This is certainly… detailed.”
Mona makes a loud noise of embarrassment and leans in, quickly pulling the book from Lumine’s hands and shutting it with a loud slap. “You cannot expect me to believe that you’ve never explored worlds where women haven’t used magic to their own benefit, Lumine,” she says, stalking back to her desk to slip the clandestine little book back into its hiding hole. Even her ears have turned red beneath the wide brim of her hat, and Lumine stifles nervous laughter before Mona turns back to face her. “Goodness, it’s not like we still live in archaic times where we were supposed to pretend that these - these things didn’t happen. Mondstadt and Fontaine are particularly advanced societies, Lumine, and-”
Lumine cuts Mona off with a wave of her hands. “Mona, I’m sorry,” she says, and Mona falls into silence with a sour look on her face. “I didn’t mean to embarrass you, I promise. Of course I know about these things, but I - I wasn’t expecting for it to come up in conversation, and it just, um, went over my head.” she pauses, pleased to see Mona’s expression quickly beginning to clear. “I’m sorry. Really.”
There’s a long stretch of silence for a moment as the two watch one another in tense silence. Then, with a sigh, Mona slumps back onto her desk a little, shaking out her hair. “This has been terribly embarrassing, I hope you realise,” she tells Lumine, but the frown on her face is softening by the second. “Honestly, I never anticipated that a conversation like this with another woman could be so excruciating.”
Lumine gives her a sheepish smile, moving to perch herself on the desk beside Mona. “We can pretend it never happened, if you like,” she says, looking over her shoulder to peer at the tomes on Mona’s desk. That isn’t strictly true, of course; there’s an odd tension now permeating the room that Lumine isn’t certain will disappear until she leaves, but - best to be optimistic, right? “Or we can just move past it. I have a few questions about the spell, actually - you know, from woman to woman.”
Lumine elbows Mona gently with a smile, and Mona makes an exasperated noise. The embarrassed smile on her face betrays her, though, and Lumine assumes she’s been forgiven for now. “As long as you don’t ask any more ridiculous questions,” Mona warns, but there’s no real threat in her voice.
Lumine hums, leaning a little further back onto the desk. “I’ll try my hardest. So… um, if you don’t mind me asking, have you tried the spell out yet?”
She wriggles her eyebrows at Mona, who flicks her hair over her shoulder in one easy motion, shrugging as she does so. “I may have, once or twice,” she says, and Lumine stifles a laugh as Mona’s cheeks turn that now-familiar shade of pink. “Why do you ask, hm?”
Lumine hums, looking back to the desk. She’s never tried using magic, but she wonders if she could get a grasp on it now if she really made an effort. “I’m curious,” she admits, and her fingers itch to pull the book out of its hiding place. Maybe Mona would let her borrow it if she asked really nicely. “Was it… you know, nice? Does it actually feel good?”
Mona hesitates to answer for long enough that Lumine looks back at her in a slight panic, hoping she hasn’t offended her again. To Lumine’s surprise, Mona is staring right at her with an unreadable look on her face that makes Lumine’s nerves flare. “Yes, actually,” Mona finally says, and there’s a quirk to her lips that Lumine isn’t sure how to feel about. “It takes a certain amount of focus that makes it difficult at first, but - well, it’s as I said. Practice surely makes perfect.”
Hm. If even Mona struggles with it, maybe it’s not really worth asking about. Plus, Lumine isn’t sure she can make the best out of her Visions yet, either - how would the tentacles even form with Anemo or Geo? Best to ask, surely.
At the same time as Lumine opens her mouth to ask about learning magic and borrowing certain books, Mona herself begins to speak, her voice almost uncharacteristically hesitant. “If… you would like me to show you, I… I wouldn’t be adverse.”
Lumine pauses. Does Mona mean she wants to…? No, she probably means showing her magic, obviously. Head out of the gutter, Lumine. “Oh. Like… showing me how to use the spell? I was actually going to ask-”
“What did I say about silly questions, Lumine?” Mona interrupts, fixing Lumine with a look that has Lumine guessing that she’s on her last warning. “Of course not. I certainly don’t have the time to explain ancient forms of magic to you, particularly not when you’re not especially gifted in the art of water-based magic. I mean…” Mona leans in a little, inching her hand closer to where Lumine is sitting. “I would be happy to show you how I use the spell. Only if you’re willing, of course.”
Lumine thinks her heart stops in her chest for a moment. Her mind goes entirely blank; all she can focus on is Mona and her long eyelashes and clear eyes and pink cheeks, and how all those pretty features might look to Lumine when she’s completely at Mona’s mercy.
Mona is just beginning to look concerned when Lumine snaps out of it. “Yes!” Lumine says, and if she’s a little overenthusiastic, she can’t bring herself to feel embarrassed about it. This is the closest she’s come to making a certain little fantasy of hers into a reality, and she’s certainly not going to let it slip between her fingers. “If you want to, then yes, of course!”
Mona doesn’t even try to hide the pleased little smile that slips onto her face after Lumine’s over-excited exclamation, and it sets something deep within Lumine’s belly aflame. “Very well,” she says, pushing herself up off the table with ease. She turns to pull the little book out of its hiding spot, and Lumine allows herself just a glimpse of the curves of Mona’s waist and thighs that her leotard does absolutely nothing to hide. “If I can be frank with you, I haven’t done this before with anybody else,” she says, leaning back up and holding the book up with a triumphant noise. “So, I’m going to quickly read over the spell once more just in case, but you really needn’t be afraid. If you say no at any point, I’ll stop.”
Lumine nods, hopping off the desk. She’s itching to pull off her boots and cape and gloves - her dress, even, until she’s there in her bloomers and brasserie. Instead, she decides to simply stand and wait for Mona’s direction. She’s already proven she’s eager enough, anyway.
It’s a little awkward for a moment; she stands, waiting for Mona to finish flicking through the pages of her book with a speed that Lumine finds impressive. Just as she’s about to speak, to maybe ask if she should go sit on the bed, Mona pauses in her reading, her sharp eyes falling on Lumine over the pages of her book.
“Well?” she says, and Lumine suddenly feels pinned in place. “What are you waiting for? Get undressed.”
Lumine feels embarrassment and arousal in equal amounts as Mona watches her, her expression perfectly neutral. She’s never really had an experience like this - being told what to do as somebody else watches - but it’s making her feel hot and flushed in a way she didn’t realise she liked until now. Mona doesn’t look away until Lumine bends to pull off her boots, and she manages to remove her gloves and cape and carefully place them in a pile on the floor without fanfare. She’s just managed to grasp the zipper of her dress between her fingers when Mona closes the book - a lot more gently this time - and directs her gaze to Lumine.
“Turn around,” she says, spinning a finger as she moves to stand in front of Lumine. “Let me help.”
Lumine does so silently, and the soft, silky feeling of Mona’s gloves brushing the long pieces of her hair over her shoulders makes Lumine shiver, goosebumps breaking along her arms. It’s perfectly quiet in the room other than the sounds of Mona’s many astrological supplies making tinkling little noises as they work, and Lumine feels like it’s getting harder to breathe by the second.
Mona pushes the zipper of Lumine’s dress down with ease, and it falls to the floor with a slight tug at the hips, pooling at Lumine’s bare feet. “There you are,” she says, and her voice is so close to Lumine’s ear that it makes her jump. Her heart is beating so hard in her chest that she wonders if Mona can hear it. “Turn back around for me.”
Lumine does so in silence, her breath caught in her chest. She isn’t self-conscious, not even remotely, but she has the odd urge to cover herself up. Mona doesn’t allow her the chance; she steps closer, into Lumine’s space, and her gloved hands reach out to hold Lumine’s waist. There’s a moment of quiet where Mona does nothing but look her up and down before she speaks, the pleased look on her face making Lumine flush. “Your frilly bloomers are cute.”
The tension suddenly snaps, and Lumine and Mona burst into simultaneous giggles. “Um, thank you,” Lumine manages, peering down at her white bloomers. “They don’t really match my brasserie, though. Black and white.”
“No,” Mona agrees, and there’s a twinkle in her eye as she says, “So which piece are you going to take off first?”
Lumine feels her cheeks burn at the words. She didn’t think Mona would be so - so confident, so commanding, but… it’s certainly welcome. “Do you have a preference?”
Mona hums, placing a finger on her chin as she looks Lumine up and down once more. “I’m thinking the brasserie first,” she finally says, covering her smile with her finger. “I hope you don’t mind me saying this, but you have lovely breasts. I’ve, um - admired them for a while.”
Lumine laughs again, a little giddy with nerves. “I don't mind,” she admits, reaching her hands behind her neck to where her brasserie is clasped shut. “I feel the same about - about, um, yours. Do you even need to wear a bra?”
Mona smiles, smug and pleased in equal amounts. “Thank the Archons, no,” she says, conversational even as her eyes fix themselves on Lumine’s chest, watching as she undoes her brasserie. “I had my leotard specifically fitted to make sure I would never have to, and - oh, Lumine.”
Lumine’s brasserie falls to the floor, the black fabric striking against the perfect white of her dress. She resists that same urge to cover her breasts with her arms and is thankful a moment later when Mona steps even closer, nudging her clothes out of the way at their feet. There’s a moment of hesitation as Mona slides her hands up Lumine’s waist; Lumine nods, almost imperceptible, and Mona is cupping Lumine’s breasts gently a moment later, her gloved hands warm against Lumine’s bare skin.
“So pretty,” Mona says, more to herself than to Lumine, and the heat smouldering in the pit of Lumine’s stomach burns hotter. Mona’s fingers trace the shape of her breasts until her thumbs reach Lumine’s nipples, quickly tightening at the sensation of her silken gloves. “I couldn’t resist touching you myself before I make good use of this little spell.”
“I wanted you to,” Lumine says, and it’s hard to stop herself from gasping when Mona flicks her thumbs across Lumine’s nipples. “I- I’ve thought of this before, of you, when-”
“When you touch yourself?” Mona interrupts, looking at Lumine from under the brim of her hat with an intensity that makes Lumine’s cunt throb. She can already feel herself growing wet, and she’d be a lot more embarrassed if she had the attention to spare. “You think about me, Lumine?”
Lumine nods, unable to find the words to form an intelligent sentence. Mona makes another one of her pleased noises, focusing her attention back on Lumine’s breasts. It takes everything Lumine has to stop herself from arching her chest into Mona’s hands, to close the space between them until their bodies are pressed together, until she can fit Mona’s thigh between her own and make her feel what she’s doing to Lumine. She ignores the urge to push and take control, though - she’s willing, wanting, to let Mona take the reins.
It doesn’t take long for things to escalate, until Mona is sliding her hands down Lumine’s stomach, pressing in closer, hooking her fingers into Lumine’s bloomers. “I think it’s time we take these off,” she says, watching Lumine with an intensity that has her flushing hot. “Regardless of how cute they are, I think they’re in the way.”
Lumine breathes out a laugh, nodding, and Mona stifles a smile of her own as she eases Lumine’s bloomers off with ease. It’s a little embarrassing, just for a moment - a glossy trail of her wetness sticks to the fabric of her underwear, and she bites her lip, desperately hoping that Mona doesn’t think she’s - strange, or gross, or-
Mona makes a noise of surprise when she sees it, but looks back up at Lumine with a heat in her eyes that Lumine didn’t expect. “Archons, Lumine,” she says, yanking the bloomers the rest of the way until they fall at Lumine’s feet. Lumine steps out of them, and Mona is on her as soon as she’s back on both feet. Mona’s hands find her hips and she pulls Lumine against her; her thigh slots against Lumine’s, the smooth texture of her tights unusually pleasant against Lumine’s cunt.
There’s a pause for a moment, as Mona peers down at Lumine, tension bubbling between the two. It builds until Lumine can’t stand it anymore, moving her hands to Mona’s shoulders as she coaxes her down, careful of the brim of her hat, until their noses bump. “Oh,” Mona mumbles, but Lumine has no time to react before Mona is leaning in and pressing their lips together.
It’s gentle at first, and it’s nice - Mona’s lips are soft and warm, and the ornaments at the end of her pigtails brush Lumine’s bare skin, leaving trails of goosebumps behind. It doesn’t take long until Lumine is breathing a little harder, until Mona is tilting her head ever so slightly, until Lumine is nipping at Mona’s mouth and pressing down against her thigh.
She sighs into Mona’s mouth as Mona brushes her tongue against Lumine’s lower lip, her thigh grinding back against Lumine in a way that has her shivering. “You’re so good at this,” Mona whispers, her breath hot against Lumine’s mouth. Lumine doesn’t have the chance to respond before Mona pulls her back in, her tongue flicking against Lumine’s until Lumine is squirming, grinding down onto her thigh mindlessly.
Lumine barely even realises they’re moving until Mona pushes her back onto her bed with ease, her thigh still firmly between Lumine’s legs. Lumine goes easily, falling back onto the soft sheets. She nips at Mona’s mouth once more before Mona pulls away with a breathy noise, her mouth red and her pigtails already a little messy. Mona’s gaze is heavy, her eyes dark, and it feels good to be under her like this.
“I’ll be sitting on the chair at the foot of the bed, watching you,” Mona tells her, and Lumine’s breath stutters in her chest at the sheer thought of it. “I can’t wait to see how you take it. I’m certain you’ll love it.”
A moment passes by and she’s gone, sitting exactly where she said she would be. Lumine feels distinctly colder without the warmth of her body, but she doesn’t have much time to mourn the loss before Mona is muttering the spell under her breath. Suddenly, there’s a brief pop, and the air glitters before Lumine’s eyes as those same tendrils form once more, swirling until they’re the same length and thickness as before.
Lumine has half a thought to try and see where on earth they come from and how Mona controls them, but the opportunity to do so is taken from her as quickly as the idea appears in her mind - the tentacles quickly wrap themselves around her ankles, skirting and twisting up her legs until her thighs are spread. She’s breathless with the sensation of it, with knowing Mona can see it all happening - knowing that Mona is the one doing this - and she can’t help but moan as more tendrils find their way around her wrists, weaving their way around her arms until they’re held firmly above her head.
“Very pretty,” Mona coos, and she sounds positively thrilled at the little show in front of her. It makes Lumine’s cunt throb, and she can’t help the little, desperate noise she makes at the praise. “Oh, I know you’re going to love this, Lumine. Just enjoy it, okay?”
Lumine nods, her eyes falling closed despite herself. It’s overwhelming in the best way - the oddly cushiony tentacles keep her exactly where they want her, tight enough that she knows that she’d have to fight her way out of their grip. They’re pleasantly cool against her flushed skin, and - she wants to feel them, she realises.
“What should I do with you first?” Mona asks, and it sounds more like she’s speaking aloud to herself than actually asking Lumine. “Should I play with those gorgeous breasts of yours, or should I start properly warming you up, hm? Though you’re certainly wet enough for it already.”
Lumine’s breath quickens as the tendrils pull her legs further apart, and the thought of Mona looking between her spread legs, where she’s hot and wet and dripping onto the sheets makes her moan, her face flushing hot. “Whatever you want,” Lumine says, breathless and more desperate than she’d like to admit.
“Whatever I want?” Mona repeats, and she sounds satisfied. “How kind of you, Lumine. I’ll remember that.”
Lumine starts when another tentacle touches her stomach, pressing against her with the gentlest amount of pressure. She pulls her eyes open again, staring at the ceiling with unfocused eyes as she feels it slide up her stomach and to her chest. It curls loosely around one heavy breast until the narrow tip of the tentacle reaches her nipple, circling tighter until it pinches pleasantly. She moans again, her back arching into the sensation.
This continues uninterrupted for a moment, as though Mona is happy enough to watch her like this, until another cool tendril mimics the first on her free breast. The tentacles pinch and loosen in an opposing rhythm until Lumine is squirming, making quiet little noises she can’t quite hold back. Her legs are still wide open, her slick dripping onto the sheets below her as she writhes, and the thought of how she must look to Mona makes her moan louder, her eyes falling shut once more.
“So loud,” Mona teases, though her voice is breathier than Lumine has ever heard it before. “Shall I do something to help keep you quiet, hm?”
“If - if you want that,” Lumine pants, her body straining against the tentacles constricting her arms and legs. “I, oh, Mona - I don’t mind,”
Mona hums for a moment before there’s another slight whoosh, and Lumine opens her eyes to see a thick tendril of water hovering above her, swaying slightly as it waits for Mona to direct it. Lumine watches it glisten above her until it moves, lowering itself until it prods gently at her mouth.
“Good girl,” Mona says, her voice low, and that’s all the encouragement Lumine needs to part her lips and let it slip inside. The tentacle is colder against her tongue than it is against her body, but it doesn’t particularly taste of anything at all. It’s thick enough to fill Lumine’s mouth but not enough to make her gag or choke, and she vaguely wonders how Mona knew just what size would be best. The thought of Mona doing this to herself, lying on her sheets with a tentacle fucking her mouth and her cute tits at the same time, makes Lumine moan throatily against the tentacle in her mouth. “Suck it, Lumine.”
Lumine does as she asks, sucking at the tentacle until she feels her cheeks hollow slightly. She quickly falls into an easy rhythm; the tentacle gently fucks her mouth while the two on her breasts pinch and pull and squeeze until her mind swims with the sensations. Mona seems happy to let it happen, no doubt watching from the foot of the bed, until the sound of a chair gently scraping against the wooden floor makes Lumine jump.
There’s the slightest click of heels against the floor and suddenly, bare skin touches Lumine’s thigh as Mona runs her fingertips through the slick dripping onto her thighs. “You’re so messy,” she sighs, but she doesn’t sound disappointed. Lumine pulls herself together enough to open her eyes, slightly alarmed, only to be met with the sight of Mona staring straight at her with her fingers in her mouth, sucking Lumine’s slick from the tips of her fingers. The sight is so hot it makes Lumine squirm and writhe, moaning against the tentacle in her mouth, and Mona smiles around her fingers. “What shall I do about all of this mess, hm? Shall I plug you up and stop you from making any more?”
Lumine nods, blinking hazily at Mona. Mona leans in just a little, her eyes roaming Lumine’s figure appreciatively. Her fingers pull away from her mouth to stroke along the inside of Lumine’s thighs once more, trailing up ever so gently until they reach her where she’s wet and aching. Mona drags the pads of her fingers along Lumine’s cunt with the slightest amount of pressure, running her fingers up to stroke her clit and moving them back down to press gently against her entrance. Lumine is aching, throbbing with how turned on she is, and she can’t help the way her thighs tremble against the tentacles spreading her wide every time Mona’s fingers dip into her.
“My fingers could slide into you so easily,” Mona says, her voice breathy and gentle as she teases Lumine. She’s staring straight at her in a way that makes Lumine want to cry with how much she wants her, and she rocks her hips in slight desperation. “Oh, you’re so wet.”
Mona continues like this for a little while longer, dipping her fingers a little further each time she pushes against Lumine until she’s knuckle deep and grinding into her pussy. Lumine’s cunt makes dirty, wet little noises every time Mona fucks into her, just loud enough to make Lumine flush with embarrassment as Mona coos about how wet she is, how pretty and pink her pussy is, how lovely she looks at the whim of Mona’s tentacles. The mention of her tentacles seems to pull Mona out of the little reverie she’s in, and she pauses just as Lumine begins to feel that familiar ache deep in her cunt. There’s silence beyond Lumine’s whimpering little breaths until another gentle whoosh permeates the room, and suddenly, another two cool tentacles are winding themselves up and around Lumine’s legs and thighs, stopping at her cunt.
One tendril feels distinctly thick, pulsing a little as the water it's made of ripples gently. The other is much thinner, the head of it flaring to a round shape that throbs in the same manner as its counterpart. Lumine makes another noise, somewhere between startled and eager, and wriggles her hips desperately.
Mona laughs, a noise that sets Lumine’s nerves alight, and pulls her fingers gently out of Lumine. “You’re so needy, aren’t you?” She asks, wiping her fingers clean on the inside of Lumine’s thigh. Mona doesn’t bother waiting for her to answer before she’s climbing onto the bed alongside Lumine, carefully manoeuvring herself until she’s straddling Lumine’s thigh. Lumine can feel the press of Mona’s cunt against her bare skin, heat and wetness seeping through the fabric of her leotard, and she forces her eyes open to look up at Mona perched atop her thigh. “I can see better from here,” Mona quickly explains, her cheeks red with embarrassment as she pulls off her hat, unceremoniously dropping it by the side of the bed.
After she wiggles a little more to settle herself, biting her lip as she moves, Mona flicks her fingers once more, and the tentacles waiting by the apex of Lumine’s thighs set into motion again. The thick tentacle slides easily through the slickness on Lumine’s thighs until it pushes against her cunt. Lumine’s breath stutters as she waits for it to press inside, to stretch her until she’s aching in the best way, but the sensation never comes; instead, the tentacle curves smoothly until it’s grinding against the length of her cunt, sliding between her folds in one easy motion. The thinner tentacle curls under the fatter one until the round head of it is pushed against her clit, and the two tentacles seem to work in unison; the gyration of the thinner tentacle feels amazing alone, but the slow grinding movements of the thicker tentacle pushes the smaller tendril harder against her clit with each pass, heightening the pleasure, and she hiccups out a moan with each press.
Lumine makes a noise of protest each time the fat head of the bigger tentacle slides against her entrance without pushing inside, even as her hips jolt on every push of the smaller tendril against her sensitive clit. The slide is so, so good, wet and messy and hot, but she wants it inside of her so bad, needs that space left by Mona’s fingers to be filled by the thick tentacle Mona is directing.
Mona coos at Lumine, leaning in to stroke her palms along Lumine’s abs. “Tell me what you want,” she says, her voice low in a way that makes Lumine shiver. “Be a good girl and tell me.”
With another twirl of Mona’s fingers, the tentacle in Lumine’s mouth slides out easily against the way she’s sucking on it. It takes her a moment to gather herself, to be able to pull her thoughts together enough to string a sentence together, and Mona watches her expectantly as she waits, petting at her stomach.
“Please,” Lumine finally says, her voice a touch shaky. “Mona, fuck me, please.”
The look of delight on Mona’s face is gratifying, but her pleading doesn’t seem to be enough quite yet. Mona leans in a little further, pressing the heat of her cunt down harder onto Lumine’s thigh. “Tell me how you’d like me to do it, Lumine,” she says, her voice throaty. “Describe it to me.”
Lumine bites her lip, stifling a noise she’s certain would be especially pathetic. “I want-” she starts, embarrassed and hesitant. Mona’s nails trail along her stomach, catching along her rib cage, and it makes her hips rock harder against the tentacle grinding against her cunt. “I want the big one to - to push inside of me and - fuck me.”
“How do you like to be fucked, Lumine?” Mona asks, and Lumine doesn’t miss the way her hips begin to shift against her thigh, rocking in tiny increments. “How do you want it?”
“Deep,” Lumine says, flushing with mortification. She’s never said anything like this to someone, but it’s so hot at the same time that it embarrasses the life out of her. “I want it deep, please, Mona, I’m aching-”
Mona shushes her, her hands trailing up Lumine’s chest until they join her tentacles on Lumine’s tits, thumbing at her sensitive nipples as the tendrils circling her breasts tease her. “Good girl,” she says again, and Lumine lets her head fall back onto the sheets once more, her eyes squeezing shut. “I’ll take care of you.”
With that, the tentacle above her disappears with a gentle pop at the same time as the thick tendril grinding against her cunt slows to a stop, the tip of it trailing back down until it stops at her entrance. She’s so wet that it makes the tentacle slippery, pushing against Lumine’s cunt with a pressure that makes her whine long and loud, canting her hips as best as she can with Mona’s weight now holding her down alongside the tendrils holding her legs. There’s another pause as Mona repositions herself to watch as she uses her tentacles to fuck Lumine, and then the tentacle pushes into Lumine’s tight heat, slow and easy.
It feels amazing, and Lumine babbles her pleasure aloud as it stretches her wide. It’s so thick, the water making up its form swirling and twisting in a way that has Lumine’s cunt pulsing, and it doesn’t stop - it pushes deeper and deeper until Lumine feels as though she can feel it in her lower stomach, in her throat, until she makes the slightest noise of discomfort and Mona stills it in a second.
“Is this what you meant by deep?” Mona asks, a little smug, and Lumine groans, her hips grinding circles against the fat tendril stretching her cunt wide. “Tell me how it feels, Lumine.”
“So, oh - good, Mona, yes, fuck-”
Seemingly convinced that Lumine is enjoying herself, Mona has the tentacle pull out just the slightest, until a rhythm forms - it fucks into Lumine slow and deep and hard, gyrating with a current that drags against the walls of Lumine’s cunt in all the best ways. Lumine can’t help the noises she’s making; she sobs aloud, barely able to make out Mona, please, yes between her shuddering moans. Despite the thick tentacle fucking her full and the tentacle grinding against her clit, both still somehow cool against the heat of her pussy, she’s still hyper-aware of the way Mona is grinding her own wetness against Lumine’s tense thigh, whimpering and gasping out her own little sounds every now and then.
It’s Mona’s own sighs of pleasure that force her to pull her eyes open, to tilt her head just enough to be able to watch Mona getting herself off on Lumine’s leg from the view of her spread open on a tentacle alone. Lumine wonders faintly what she must look like - her arms pulled taught above her head and legs spread wide by thick, blue tendrils of water; her tits encircled by thin, teasing little tentacles that pull at her tender nipples and squeeze at her breasts; her puffy, pink cunt spread wide around a churning tentacle that shines with her wetness. The image of herself has her squirming, choking back pitching moans as best she can.
Of course, all the lip-biting in the world couldn’t force her to stay quiet when the tentacle inside her pushes up against her sweet spot in a way that has her almost shrieking, gasping out unintelligible sounds as she grinds her hips in an attempt to chase the sensation. Mona catches on quickly, leaning further over Lumine and canting her own hips harder into the muscle of Lumine’s thigh, the slickness coating the skin making the slide wet and easy.
“It’s so good, isn’t it,” Mona gasps, and Lumine doesn’t think she’ll ever be able to get the sound of Mona’s fucked-out voice out of her head. “So thick and deep and- oh, oh, yes, ah - good.” She rocks her hips harder against Lumine, biting her lip as she watches Lumine through heavy-lidded eyes. “I - I thought about this, about y-you, when I was doing this alone,” she admits, and Lumine can’t help the way she pulls at the tentacles holding her arms, so desperate to pull Mona in close. “I didn’t… didn’t think it would hap- oh!”
Mona breaks off with a moan, her hips working in smaller circles against the muscle of Lumine’s thigh. Lumine can feel how wet she is through her leotard, dripping onto Lumine’s thigh with wet, dirty noises audible even over the sound of the tendril fucking into Lumine’s cunt, and it pushes her closer and closer to the edge until she’s teetering, her hands clenching into fists as she yanks against the tentacles holding her tight.
“Mona, Mona, please, I can’t take it,” she sobs, doing her best to keep her eyes on Mona. Mona looks up from where her head had dropped forwards in her own pleasure, the ornaments at the end of her pigtails dragging against Lumine’s skin. “I’m so close, Mona, let me come, please, I-”
“I know,” Mona interrupts, her own voice breathy and lilting as she pushes herself against Lumine’s thigh. There’s a moment where she struggles against her own pleasure, her head thrown back to expose the shape of her throat before she snaps out of it. She moves from where her hands had been fisting the sheets on either side of Lumine to press a hand down against Lumine’s lower stomach, moaning and grinding back harder as she does. “I can feel it inside, Lumine, oh-”
It happens quickly, then - the sensation of Mona’s hand pressing down on where she’s being fucked hard and deep elevates the sensation of the tentacle grinding against the walls of her cunt until she’s whimpering, her hips jumping in tandem. The thought of Mona feeling it happen, of Mona getting herself off with Lumine as she watches her get fucked - it’s so much, almost too much, and the tension within Lumine snaps as she shrieks, her fists clenching tight and her back arching as she comes.
The force of her orgasm leaves her breathless and shuddering, the thick tendril inside her stilling as she clenches down on it over and over. Her cunt is pulsing, her thighs shaking against their hold, and she’s only barely capable of opening her teary eyes once more to watch Mona shake apart against her thigh, whimpering and moaning Lumine’s name. She doubles over herself, her hair ornaments swinging as she grinds to a stop, shivering with the intensity.
There’s a second where Mona lets the aftershocks of her orgasm run through her, and then she’s collapsing onto Lumine. The tentacles disappear in an instant, leaving Lumine spread eagle on the bed, her cunt clenching around nothing and her body jolting through her own aftershocks.
“Oh, Archons,” Mona finally says after a long moment of mutual silence. “I have a feeling that my soul may have just left my body.”
Lumine laughs, exhausted, sore, and unbelievably well-fucked. “I know,” she manages, blinking up at the ceiling with bleary eyes. “Wow.”
“Wow indeed,” Mona mutters, and Lumine feels her pushing herself up. Her hips judder once more against Lumine’s thigh, and she gasps with oversensitivity as she pushes herself up and off. “Are you quite alright? I’m afraid I might have gone a little overboard on you.”
Mona sounds genuinely guilty, and Lumine does her best to lift her head, smiling at her. Something in her face has Mona relaxing from where she’s crouched over Lumine, concern evident on her face. “It was good,” Lumine says, and concern melts into a prideful little smile. “So good, Mona.”
“Ah,” Mona says, and she sounds far too pleased with herself. “Well, I’m pleased to hear that. Still, though, can you… move?”
Lumine shakes her head. She should probably feel shy about the way she’s lying on Mona’s bed, her legs spread wide and her arms still loose above her head, but - well. The time for that has probably passed, honestly. “I would if I could,” Lumine tells her, letting her eyes fall closed. “My, um - everything is on display right now, if you hadn’t noticed.”
Mona makes a little oh before she shifts again, carefully pushing Lumine’s legs closed. Lumine can’t help the giddy giggles, and after a moment, Mona falls beside her, smothering a grin into Lumine’s shoulder. “My sheets will be completely ruined,” she says, her voice muffled. “I should’ve placed down a towel.”
“I don’t think a towel could have helped,” Lumine mumbles. She feels pleasantly floaty, now, and she isn’t quite ready to move and ruin it just yet, even despite the slick drying on her skin and the hint of hunger of her belly. “I don’t think I’ve ever been so wet before.”
Mona stifles a snort, but doesn’t say anything. The two trail off into a companionable silence for the next few minutes, Mona’s arm comfortable around Lumine’s waist. Lumine is starting to doze off into a comfortable little nap, until -
“Mona, was that rumbling sound from your stomach?”
“I - absolutely not! Don’t be ridiculous!”
