Chapter Text

You sigh heavily and rest on your forearms as you lean over to watch Bela and Daniela play with the girls. You wander away toward the opposite side of the castle, hugging yourself the entire time. Upon arrival to your destination, you knock quietly and wait for approval to enter. Alcina stands outside on her balcony with cigarette holder in hand. Since the birth of your first daughter, she's begun smoking outside exclusively. She hates it but she'll do absolutely anything for her new grandchildren. You don't have to say anything, she knows why you're here. She snubs her cigarette and takes a seat on her love seat inside the room, you crawl up onto it and lean into her side. She caresses your shoulder lovingly; her steady breathing slows your own and you sink into her with relaxation. Throughout your entire postpartum Alcina has been a rock for you; Daniela and Bela are wonderful mates and even better mothers, but their support is limited.

Alcina, and surprisingly, Mother Miranda on the other hand have been nothing but unconditionally supportive. They've guided you through your worst episodes and helped you feel like yourself again. That is, until recently. Your doubts about Cassandra are worse now. Shortly after the birth of your youngest, she became extremely defensive to the point she almost harmed your oldest. That caused a huge fight between her and Daniela, and unlike Bela, Daniela barely made it out intact. Since then, Cassandra has been avoiding the entire family, she doesn't come down for meals. You also haven't talked to her since.

"Do you want me to speak with her?" Alcina asks.

"No. I know where she is, but, did I make the right choice? Choosing Bela and Daniela first. What if Cassandra isn't ready?"

"I cannot say for certain if she is or isn't, but I will say that she is fighting a great battle right now. Her alpha is telling her to kill your children because they aren't hers. Bela went through the same thing, only she hid it better."

"What?!"

You sit up looking up at Alcina. Bela never mentioned anything about it, you had your suspicions, but she eventually warmed up. Maybe Cassandra will too? You sigh heavily and rub your temples, slightly regretting becoming their mate. It was fun while it lasted, but now it just gives you a headache. You'll be glad when this is over. At least.... until they want more. Daniela already is trying.

* * *

Cassandra is pacing around, meticulously reorganizing the weapons and suits of armor for the millionth time. You lean up against the stone wall as you watch her, she turns to face you and huffs before returning to her task. She continues to ignore you until you stalk around the center of the room and intercept her. Cassandra postures, she looks down at you as you pull her aside toward the nearby table. Without a word she clears the weaponry and props you up onto the table, she leans into you and sniffs your neck. She scoffs. You smell like her sisters and their bastards. There's nothing of hers on you, even her mark has begun to fade. Before she can turn away you lock your legs around her, forcing her to stay even though she can easily swarm free.

"What do you want?" She grumbles.

"You to tell me what's going on."

"You already know the answer to that." She spits.

"Come on now Cassandra-"

"Why am I the last one? Am I not the strongest? The best huntress? Is it because I'm not as caring as Bela? or as romantic as Daniela? Those gremlins are running rampant and neither of them are mine. I should kill them!"

"But you won't." You warn, cupping her face, "I saved you for last because you are the best. You are the best huntress, the best fighter, and you're so protective. I know you killed that pack of lycans that wandered too closely to the castle when Sona was born. I also know that you secretly watch Iveta whenever she gets too near, and I may have heard from a little bird that you kept her from finding a stash of weaponry. I know your alpha is telling you to kill them, but deep down you love those girls as if they're your own."

Cassandra doesn't look at you, she continues to hide her face, but her body relaxes in your hold telling you that she's listening. She's trembling. She hates her alpha for wanting to kill innocent lives, she hates you for picking her last, she hates how much she loves and cares about you.

"You're not mad at me?"

"Why would I be mad at you for having an instinct, and actively choosing not to listen to it? I'm disappointed that you didn't tell me or come to me sooner. I love you so much Cassandra, and I know you love those girls."

You kiss her shoulder, and she purrs quietly as her arms wrap around you and tightly hold you to her body.

"Can you forgive me?" She mumbles.

"I'll forgive you on one condition" you scoot your hips forward catching her attention, "not only you apologize to the girls, and your sisters, but you show me how sorry you are for not giving me any attention."

Cassandra lifts her head up, her eyes darkening as she looks you over and smells the sudden shift in the air. You haven't been touched since the birth of Sona. Not that you wanted to be touched. You knew how sensitive Cassandra was feeling and wanted to make sure you were completely hers. She knows this. She smirks and eases you down onto the table, then lifts your legs and undoes your shoes before helping you scoot your pants off.

"You know, I really miss you wearing your maid uniform. Made this so much easier." She complains.

"Maybe I'll wear it for old times' sake once everyone leaves."

Cassandra looks up at you with a flash in her eyes, she really likes that idea but the old maid uniforms are too puritan compared to what she has in mind. Already you're soaking from her looks alone, from her smell which is your favorite out of the three. She drags your underwear off easily and buries her face between your legs, instantly devouring your cunt. You moan and toss your head back, arching your back and hips into her while your hands instantly go to her head. Your fingers tangle in her hair, pushing her hood back as her tongue explores every fold and crevice. Cassandra scrapes her teeth occasionally against your clit until it is nice and swollen with arousal, then she takes it in her mouth and swirls it with her tongue. She sucks on it and flicks it, making you tremble and gasp from the acute sensitivity.

She eats you like her last meal. Savoring how wet you become from her tongue alone, she releases your clit and pushes her mouth onto you, diving her tongue as deeply as it'll reach inside. You clench and buck your hips, feeling her tongue sends tingling warmth over your body as it wiggles and explores inside you. Just as you tense up, she stops, pulling her face away from you and moving herself to hover. She growls lowly, tugging at her dress that suddenly feels constricting and hot. Wrapping your arms around her, you aid in taking off her corset and once it's off she pulls her dress off followed by her underwear. The entire armory fills with arousal and becomes almost stuffy despite how cool the atmosphere is.

You pull Cassandra down and kiss her deeply, tasting yourself on her lips as her tongue shoulders through into your mouth. Moaning, you return your arms lazily around her shoulders as she props herself up and aligns herself with your entrance. Your begging is muffled by the sloppy kissing, so you grind your hips into the air and urge her with your legs around her waist. Cassandra presses into you as she fully hilts herself inside you, making you break the kiss and let out a surprised scream. She thrusts brutally as her arms come down and pin you, squeezing you to her body as she rocks the entire table. You gasp with each thrust, trying desperately to catch your breath and only letting out pathetic, broken moans in the process.

"Fuck you feel so good" Cassandra moans.

She loves how your walls stretch to fit her, every time she thrusts she feels you tense and quiver. Your orgasm isn't far and she knows from the way your toes curl, your hips buck, and the hitch in your moaning. Cassandra's sharp nail rip at your clothing as she finds her faded mark and bites down hard. You scream from the pain but it sends a tidal wave of confusing signals down your body as your orgasm hits at the same time. Your legs tense and shiver, you lift your hips and suck in a last breath before your entire body tightens and a wave of pleasure washes over you. Cassandra groans loudly as you clamp down on her, she forces in her knot and releases her seed deep inside you. She bucks her hips a few times to fully seal her knot inside you all while her fangs sink deeper into your skin.

Carefully she lets go and licks the stray beads of blood up, as your body relaxes and shifts to get comfortable on the table. She buzzes loudly and kisses her fresh mark, making you hiss in pain but hold her tighter nonetheless.

* * *

"Are you almost done?" Cassandra asks impatiently.

"Ask me again and I'm taking it off" you threaten.

You grunt and finally get the last button done; it's much harder doing it by yourself, but you wouldn't be caught dead wearing this in front of anyone else. You tug uncomfortably at the tight material, but you did say you would try it at least once. Now you're regretting it. With a last huff you step out from behind the changing curtain wearing the very short maid uniform that Cassandra got you. Where she got it is a mystery, you really try not to think about poor Donna sewing this lewd outfit. The skirt stops at your mid thighs, the "apron" just above the hem of the skirt. The top is a button up short-sleeve blouse that stops mere centimeters from your nipples, leaving your breasts almost entirely exposed. You pull one more time on the skirt, attempting to stretch it downward with no success.

At least the look Cassandra is giving you makes up for this; her eyes trail your body hungrily; her mouth is curled to show off her fangs that she licks sensually. The tent in her dress is the biggest compliment, you haven't done anything yet and already she's excited. If you listen closely over the crackling of the fire, you can hear her panting as she stares at you. By the Black God how she wants to ravage you like a wild beast; pin you down, mount you, and fuck you into an incoherent mess. She didn't think the uniform would have such an impact on her.

You clear your throat and prepare your best impression from when you were a servant.

"You wanted to see me, Lady Cassandra?"

Cassandra growls, for a moment you think she's going to forgo the entirety of what the two of you talked about. She stands and rigidly approaches; stopping just far enough where the tip of her tent is within inches of you. Her golden eyes take you in one last time before she smirks and holds her sickle up to your chin, using the flat edge to force you to look up at her. She loves getting off on the smell of fear, she's used to maids reeking of it when she speaks down to them. She remembers when you used to smell like it, but now you can't help but smell like excitement and joy around her. Cassandra chuckles dryly.

"I did. Do you know why?"

"I'm afraid I don't."

"Well then, allow me to illuminate you."

She grabs you by the throat and slams you against the nearby wall, it's not hard but it's enough to make you gasp and grab onto her hand out of instinct. A jolt of fear and excitement strikes you, knowing how easily she could lift you up with one arm and choke you. Yet she lets you stay standing, and her hand only squeezes enough to make lightheaded before easing.

"I called you here because I want to hear you admit that you want me. I see the lustful way you stare at me, how you basically present yourself to me when I walk by, even now-" her sickle clangs to the floor, she pulls off her glove with her teeth.

You swallow as you watch her, the action itself sending a flood to the apex of your thighs. Cassandra puts her hand up your skirt and douses her fingers in your obscene amount of slick.

"Even now you're soaking at the mere thought of me. So tell me, what do you want? Do you want me to fuck you like you slut you are? Drive my cock and bury my seed into you until the whole castle smells me on you?"

"Ho oh y-yes" you moan out as her fingers tease your entrance.

"I'm sorry. I didn't catch that."

Cassandra leans in closer, her erection rubs on your thigh, and you feel the slight wetness from her precum leaking through. She's as aroused as you are. Two fingers slide inside you; you moan and arch your hips into them.

"Yes. Please. I want you. I want you to fuck me." You moan.

"Then show me. Show me how desperate you are to be fucked."

Cassandra keeps her fingers inside you, and you start grinding your hips up and down, riding her fingers. A lewd squelching noise fills the room from how wet you are as you pick up speed, her fingers curl slightly and press right into your spot. You tilt your head up and moan loudly, her hand tightens to cut you up and the light headedness returns. Her fingers aren't as thick, but they feel so good inside, rubbing your walls and pushing the most sensitive parts. Your orgasm rises quickly, and your riding becomes erratic and sloppy. Cassandra feels you tensing up and decides to take her fingers out just before you reach your peak. You groan loudly at the empty feeling and continue to grind your hips looking for friction. Cassandra pulls you by your neck and guides you to the bed where she pins you down by the neck with your ass in the air.

"Stay just like that pretty girl and I'll reward you."

You do as she says, subconsciously your omega is loving this as you lean into the bed to further present yourself to your alpha. Your soaking cunt up in the air, and chills down your spine every time a slight breeze blows by. You can hear Cassandra undressing, her clothes hitting the floor only ignites your anticipation as you bite your lower lip and whimper softly. The bed dips behind you and Cassandra returns her hand to your neck, further pushing you downward but not cutting off your air access. Her cock rubs between your folds, using your own slick as her personal lube.

"That's right pretty girl, I'm going to take good care of you and I want the whole castle to know what a dirty, little slut you are and who you belong to."

Her other hand lands firmly on your ass cheek, you whimper and flinch forward but her weight on top of you prevents that. Cassandra eases her cock in this time, it slides in without any friction or resistance, and you loudly moan until she's entirely sheathed. She sits for only a moment to let you stretch and adjust to her, when you give a quick nod she rests her chest onto your back and begins thrusting. Her balls slap against you every time her hips meet yours, it's hard to tell if the slapping sound is coming from her balls or her hips hitting your ass.

Cassandra grunts lowly, mixing with your unashamed loud moans which only spur her on. You gasp and moan so much that drool begins to form in the corner of your mouth on the bedsheets, sweat drips down your forehead even with Cassandra's cool body on yours. Her cock stretches your walls and hits your cervix with every deep thrust sending shocks of painful pleasure through you. As your orgasm approaches you arch your back up, clench with your thighs and tightly grasp onto the bedsheets. Cassandra releases your neck and wraps her arms around your body, her knot already forming and threatening to enter with each hard buck of her hips.

Her pounding becomes slower but harder as she slowly stretches you until her knot slips in and locks into place. You squeal feeling it stretch you and one arm shoots back to dig your nails into Cassandra's arm as you orgasm claws through you. Your entire body shakes, your legs clench and tighten, your back arches up and down as warm tingles permeate your whole being. Both you and Cassandra pant heavily as her warm seed fills you, you feel every thick rope shooting out.

"Don't think I'm done with you."

* * *

She wasn't lying about not being done with you. The second your daughters are preoccupied with something, she drags you away, mounts you, and fills you until she's satisfied. Bela and Daniela start giving you a wide berth because they fear Cassandra attacking them, and because they can smell their sister on you. She fucks you at least once a day, more if she can resist knotting you. Then she doesn't have to wait as long! By the time your heat is about to arrive all you can do is lay in bed from how sore your poor, abused cunt is. You don't even bother wearing underwear because Cassandra's copious amounts of cum have ruined them all. As if she knows, when the first heat cramp arrives, she's there. Her alpha wants her to breed you in the most effective way possible, because this is her only chance! However, after some 'gentle' threatening, she slows down and goes at your pace.

Cassandra gives you an abundance of foreplay. Unlike the last few weeks where she came in with little to no warning and instantly started fucking you. This time she spends time on your breasts, taking the nipples in her mouth and sucking them. Grazing her teeth over them until they are nice and firm before moving onto the next one. She leaves hundreds of tiny hickies along your body, starting at your neck and ending at your thighs. Her kisses are tender and soft, even when she down lay between your legs she treats you softly. Her tongue is nice and cool on your swollen cunt, she plays with your clit until it too is swollen with arousal.

Her tongue works magic on you. It runs up and down the entirety of your cunt and she circles your clit just the way you like. Cassandra sucks your clit gently and brings you to your first small orgasm quickly. You lift your hips and press her face down as you ride out your orgasm on her face. She kisses up your body and whimpers softly, you look between your bodies and see her poor erection. It twitches with want, precum dripping from the top and landing on you. You give her the go-ahead and she carefully hoist your legs into the air. She continues her slow and steadiness, letting you adjust to her length and girth before proceeding. You sigh contently when she's all the way in, and she doesn't start moving until you tell her to.

Your omega hates how slow Cassandra is going; she too wants Cassandra to fuck her the same way she has the last few weeks; your body however, loves it. You feel every slow thrust, the widening of your walls, your walls clamping onto her, the steady formation of her knot inside you. Cassandra's thrusts are deep but short, she doesn't pull as far out and her knot forms in you. Soon she can't pull out at all and her knot seals inside you then she cums deeply inside you. You let out a shaky gasp and hold onto her forearms as you lift your hips and your orgasm slowly lets go. The warm tingling sensation creeps over you and you sigh heavily with relaxation as you sink into the bed, feeling her knot pulsate inside you.

The first of many, many more.

"Here's your baby" Mother Miranda states.

You look up at the monitor, seeing a form take shape on the ultrasound screen. Cassandra stands beside Mother Miranda, her eyes wide with excitement upon seeing her child for the first time.

"Wait-"

Mother Miranda moves the scanner more on your stomach, your heartbeat spikes with worry. Why did she say wait? What does she see? Is the baby okay?

"Oh my."

"What? What is it?" You ask worriedly.

"Congratulations. It's triplets."
