Work Text:
Lady Death first took notice of Agatha Harkness, the mass murdering spirit and siphon witch, the night that she survived her coven’s attempted execution. It failed epically and resulted in them lying dead at her feet, drained of magic, whilst Agatha was more powerful than ever.
Agatha was beautiful, with a bright, gleaming soul despite the cracks in her facade from surviving eighteen years of neglect and ostracization. She was bold, brash, shameless, and reminded Rio very much of a scrappy, opportunistic feline. Death watched from a distance, entranced, and approached the bodies after Agatha was long gone to retrieve their souls.
When Agatha killed another coven a few weeks later, Rio stepped forward and allowed herself to be seen by a mortal for the very first time. Agatha spat and hissed at her initially, a feral cat on the defensive as she demanded to know Rio’s business with the lifeless husks collapsed on the ground.
It was only once she was assured that Rio was not there to hurt her - and she promptly discovered her real purpose - that Agatha began to very, very slowly accept Rio’s presence in her life. And Rio, once she had her foot in the door, dedicated herself to the long hunt, the leisurely chase. Agatha was traumatized, and hurt, and petrified of letting herself be seen as vulnerable. Rio was willing to wait however long she had to for her to be ready.
It was ten years of back and forth, of Agatha killing and Rio collecting, cautious touches, and flirting over corpses, before the courting between them officially began. Agatha seemed to finally trust that Rio cared for her and was not going to turn her back on the young witch at the first sign of trouble.
Agatha was the one to make the first move. She stood over the bodies of three powerful witchqueens who tried to ‘put her out of her misery’, and smiled shyly at Death when she arrived, offering her a lovingly constructed bouquet of red roses, baby’s breath and sunflowers. Rio was exhilarated; her immense joy caused her green magic to leach out of her to transform the dead bodies on the ground into a bed of cheerful daisies.
And of course, after a decade of tension and tentative friendship between them, their relationship flourished. Within weeks, they realized that they had technically been courting all this time without knowing it. They saw no reason, once that came to light, to continue with their slow and steady pace, and they let their relationship progress naturally.
And since they were lesbians, naturally happened to be extremely fucking fast.
It was difficult, considering that Rio could not be around all the time, her visits infrequent and short, although she tried her very best to make them as significant as possible. Often, Agatha would summon her by committing the mass murder of a coven, just for the excuse to see her. Agatha would gift Rio bodies, and Rio would appear with pink hydrangeas and sweets from far-off lands, greeting her with a kiss and praise over how skilled a hunter she is, which would make Agatha preen.
It wasn’t long before they tumbled into bed together, Agatha taking the lead as she taught the virgin Death everything she knew about pleasure, having seduced quite a number of young witches during her youth. Agatha essentially taught her how to be human, as Death, as a cosmic entity, very rarely took on physical form. Her current body was one carefully crafted and designed for Agatha and Agatha alone, and the witch made it very clear that she was very pleased with Rio’s design skills.
Rio can’t precisely remember when they declared themselves lovers. When Agatha found an abandoned cottage in the woods a few weeks back, moved in, and invited Rio to join her, she declined at first. She was so busy with her job as Death that her visits to Agatha were sporadic, and there were times she was been unable to visit her for several weeks.
The next day, Agatha was gathering wild blueberries in the forest when she was ambushed by witch hunters wielding binding spells and poisoned arrows. Agatha was outnumbered but winning the battle until she was struck in the side with an arrow. Rio swooped in with all the fury and wrath of an enraged deity, her true form on full display.
Once the hunters were dispatched, she healed Agatha’s wound, and was shocked when her lover lively caressed her skull place, placing a reverent kiss on her exposed bony jaw with a whisper of thanks. Sue did not react with fear or disgust, but with adoration and acceptance. Death knew then that her heart would eternally belong to the young spirit witch. And so she agreed to move into the cottage with her.
Now, Rio has only been courting Agatha for five months, and already she knows that there will never be another creature in the entire universe as utterly fascinating as her.
She is still learning how to sleep. Agatha has explained that it’s a period of unconsciousness where the human brain rests, so the body can repair and restore its energy. Agatha is very fond of this activity, and takes part in it every night, insisting that it’s normal for humans; Rio reckons that she is pulling her leg, because there is no way that humans spend a third of their time unconscious.
It tends to be a thing that humans prefer to do at night, shortly after having sex. Agatha likes to latch onto Rio like a limpet and cuddle up to her after her orgasms, and then falls asleep wrapped around the cosmic entity. Rio is reluctant to disturb her from her slumber, especially when she is so cute and cuddly, so she has started to try and learn how to sleep as well.
Her favorite part of this routine is how if she remains in bed with Agatha during the night, she is permitted to wake her in the morning by eating out her cunt or slipping her fingers inside of her. Sex has rapidly become Rio’s most enjoyed human pastime, and she knows that it is Agatha’s as well.
Tonight, however, Rio’s attempt at sleep is not going particularly well. Her mind refuses to quiet, her thoughts full of Agatha. The spirit witch’s cunt tasted different last night, and seemed almost swollen, although Rio is baffled as to why.
Not only that, but she was in a terrible mood when Rio arrived home. She needed to spend a week away shepherding the souls of young children succumbing to a plague to the afterlife. They have spent longer time apart than that many times before, but Agatha was incandescent with rage last night over their separation, and then promptly broke down into upset tears when she admitted that her missing Rio was amplified greatly by her feeling unwell all day.
Hot chocolate that Rio brought her from Mexico, sweetened with honey, did soothe her body pains slightly, as did several orgasms brought about by Rio’s tongue, her healing saliva doing wonders. Nonetheless, Rio is still worried about what illness might be affecting Agatha. The very last thing she wants in the world is to be forced to collect and ferry her lover’s soul. Rio would rather cast herself into the oblivion of a black hole and allow her atoms to be torn apart than play any kind of role in Agatha’s death - no matter her responsibilities as a cosmic being fundamental to the universe’s composition.
As the sun begins to rise, light creeping into the cottage’s bedroom beyond the curtains, Rio trails her fingertips lightly over Agatha’s naked sleeping body, wondering how to wake her up today.
Should she suck on her nipples, perhaps, until her cunt is weeping and begging for stimulation? Should she slowly feed her fingers one by one inside of her, until Agatha awakens? Or should she conjure one of the magical phalluses constructed of Rio’s vines that Agatha is so fond of, and ease it inside of her so that Agatha stirs from her sleep feeling stretched and full, her clit throbbing?
Whilst Rio ponders, Agatha starts to stir restlessly beneath the sheets, kicking at them until they tangle around her legs. A strange odor fills the room that smells like blood but… different. Rio’s gaze flickers over her lover’s beautiful nude form - and then stills, fixing on her lower half. She freezes, staring in silent horror.
The sheets beneath Agatha’s ass and cunt are stained with blood, a small pool of half-dried crimson that has seeped from inside her. How Rio did not notice before, she is completely bewildered about. But she is certain of one thing. Agatha is bleeding. Between her legs. From her cunt. And if she knows anything about humans, it’s that bleeding is not good. Humans tend to need blood to maintain their fluid levels and for oxygen to circulate around their bodies.
Is Agatha dying? Her soul appears stable in her body, and is not calling to Rio any more than it usually does, when it softly and happily trills to her upon sensing her proximity. But her lover is bleeding, which can only mean something is terribly wrong.
Rio panics. Sitting upright in bed, she shakes Agatha awake desperately. “Agatha, wake up. Please, my love, wake up. You’re sick, or injured, or - I don’t know, but I’m scared!”
“Waz’goin’on,” Agatha slurs, stirring slowly.
“You’re bleeding,” Rio tells her worriedly.
Agatha blinks sleepily and mutters, “‘Kay, lick’n’heal me then.”
“No, it’s -” Rio leans in to whisper, her voice trembling with concern, “It’s down there.”
“Hmm?” Agatha lifts the sheets to peer down at herself, frowning. “Oh.” She groans and turns over onto her front. “Wonderful. I forgot it’s that time of the month.”
Rio is aghast. Agatha is acting as if this is normal. “It’s what?”
“You know, my menses. My monthly. The red curse.” When Rio continues to stare at her, bemused, Agatha mutters tiredly, “I forgot that you’ve always been away when this happened before. The majority of human women go through something called a menstrual cycle where their reproductive organs prepare for the release of an egg, so they have the chance to get pregnant. The blood is just my womb punishing me for having the audacity to be fertile but not reproducing.” She nudges Rio with her head, snuggling back into her arms so that her back is pressed to the entity’s front with an exhausted sigh. “It’s why I’ve been feeling sick. It’s normal, I promise. I’m not dying.”
“It’s your body trying to get pregnant?” Rio parrots, her stomach clenching at the idea. She feels a flicker of something hot and tight coiling deep in her lower abdomen, a subtle flare of arousal at the mental image of Agatha being round with a child. Not just any child, but Rio’s child.
“More or less,” Agatha mumbles, her eyelids fluttering. She’s flagging, being dragged back into slumber. “I’m fine, I swear. Happens every month, and has done since I reached twelve summers. I’m still alive, aren’t I? Just… tired. I’m going back to sleep. Magic the sheets clean, will you?”
Rio nods numbly, and by the time she sets her hand flat on the sheet and allows her green magic to cleanse them of her lover’s dried blood, Agatha has slipped back into unconsciousness, snoring adorably. If her bleeding from her cunt was something truly concerning, then she would not so easily allow herself to fall back to sleep.
Calm and reassured, Rio draws the spirit witch closer into her embrace, one hand gliding downwards to cradle her belly. It’s warm, flat and firm. For a moment, Rio imagines what it would be like to watch it swell, a baby growing within her, a perfect little hybrid of the two of them. It shouldn’t be possible; Rio is Death, after all, and cannot inspire Life. But it doesn’t hurt to think about it. Agatha would look beautiful pregnant, she’s certain.
Trailing her fingers over her lover’s hipbones, Rio ponders on Agatha’s words. This is the first she’s heard of a menstrual cycle. She summons the book on animal husbandry behavior she has been reading recently to better understand the creatures humans share the planet with; they are under her purview as a green witch, after all, but Rio has to be honest and admit that she doesn’t know all that much about them.
(She threw a rather large tantrum when her favorite animals, the dinosaurs, were wiped out after her sister Infinity decided to play around with meteors and direct one at Earth, so mammals are still relatively new to her.)
Carefully balancing the book on the mattress near her head, and using her free hand to flick through it, she finds the section on pregnancy. The chapter uses the domesticated wolves that the humans call dogs as its main example, and Rio’s attention is caught by a line describing the estrous cycle. That sounds similar enough to the menstrual cycle - they must be the same thing.
Rio reads on, thoroughly studying the paragraphs that explain a bitch’s ‘heat’, a short period of time in which the female dog is sexually receptive and ready to mate. Rio shakes her head reading that; Agatha is always sexually receptive, but maybe that is just something particular to her, since she does have succubus-adjacent powers.
Otherwise, Agatha has symptoms that perfectly fit with her being in heat. She’s restless and moody, both anxious and aggressive, bleeding from her vagina, swollen, and needy for sex.
Agatha must be in heat, she deduces, which means her body is craving to be bred. But Rio cannot provide that for her… can she? Would the action of mating with her soothe her unconscious desire to get pregnant? Maybe Rio can try and trick Agatha’s body into thinking she is being bred, although her current form doesn't have the equipment for that. She can, however, magically manifest a penis.
Rio reads on in the book, trying to find if there is a male equivalent to being in heat. There doesn’t appear to be, as the book iterates that males are ready for breeding all year round. Rio doesn’t need any help in learning how to court or attract Agatha as a mate - they’ve been mating an awful lot already - but she does learn that many male animals secrete sex pheromones to indicate they want to mate and breed.
Without even realizing she’s doing it, Rio’s powers reach deep into the DNA of the human body she has crafted herself, finds those buried and suppressed genes, and switches them on. She senses the change in her body as she begins to release pheromones, smelling the faint but sweet and spicy tang enter the air.
Within a couple of seconds, Agatha begins to react, even in her sleep. She turns her head minutely and inhales deeply, so that the pheromones wash through her nasal passages and lungs; her breathing quickens and shallows, and she begins to twitch, her hips spasming backward to seek pressure.
Rio hums under her breath, filled with new ideas, new kinks that they haven’t explored yet but she is now deeply, deeply intrigued by. Her hand resting over Agatha’s naval dips downward, her fingers combing through the soft tufts of dark curly public hair that covers her mons. Her fingertips slip lower, between her lover’s thighs and tracing over her swollen and slippery lips, wet with menses. A weak moan escapes Agatha’s throat as she bucks up into Rio’s touch, desperate and needy.
Rio’s tongue darts out to wet her dry lips, hungrily trawling her eyes down Agatha’s naked body. She turns back to the book briefly, skimming the passages about the process of breeding, and how animals ensure successful mating. It often, she realizes, involves violence: pinning the female down, and biting them on the back of the neck to secure them. It also often involves continuous sex until the female’s heat has ended, with the male remaining mounted to ensure the female is properly bred.
The spirit has given her blanket permission to do whatever she wants to her body to wake her. They have a safeword during sex itself to ensure everything is consensual. While Agatha is typically the one who remains in charge, preferring to be in control, she sometimes will let Rio take the reins, when she is in the mood. And when that does happen, she particularly enjoys being taken roughly.
Like a wild animal.
And since she is in heat…
Well, is it not Rio’s job and privilege as her lover to satiate her?
Agatha awakens slowly, stirred to consciousness by the feeling of something rough and wet lapping at her upper thighs. Dazed and still half-sleep, it takes her a minute or two to become cognizant of her body and her position.
She’s lying on her back, a pillow beneath her head but also one placed underneath her hips. The sheets are gone, lost to the floor, which would usually leave her feeling chilled. Instead, she feels warm - very warm. Flushed, in fact. Her belly feels tight with cramps, thanks to her unfortunate time of the month, but there’s also a burning heat there more kindred to arousal than discomfort or pain.
Her legs are spread wide, far wider than she would usually splay them during her sleep. And her wrists are pinned down by her side by two strong hands, grasped so firmly that even if she were to try and yank them free, she would remain trapped.
She falls very, very still and emits a silent gasp when she feels that hot wet thing make its way upwards, kitten licking around her vulva, and then directly over her clit. The sensation sends tingles of pleasure coursing through her, making her legs tremble as she tries to instinctively close them - but they are bullied back open by two vines, that wrap around her knees and force her legs to spread wider.
Her heart jackrabbits within her chest, as she glances downwards, and sees Rio staring up at her, her hazel eyes piercing. The cosmic entity is lying on her front between Agatha’s thighs, pinning her wrists to the mattress as she laves at the spirit witch’s pussy with light, gentle pressure of her tongue.
Splayed out as she is, Agatha is completely exposed to her whims, which allows Rio to trail the tip of her tongue through her slit and up to circle around her clitoral hood before retreating back down. Every swipe of the muscle against her most sensitive nerves feels like lightning, making her feel dizzy with want.
“Rio?” Agatha breathes.
Her voice breaks and she throws her head back when the green witch sucks her labia into her mouth, inching her tongue inside of her entrance before drawing it back out. She feels like she’s floating on a cloud, her adrenaline making her feel almost fuzzy, and briefly, Agatha wonders if she’s still asleep - if this is all just some wonderful dream.
Rio raises her head from where she has it buried between Agatha’s thighs, and her eyes are bright despite her pupils being so huge that they drown out the warm brown irises. She looks utterly filthy, Agatha’s menstrual blood staining her jaw and lips. Some is even smeared on her nose and forehead; she looks like a vampire who has just enjoyed a fantastic meal and got so lost in feeding that she didn’t care how messy it got. She props her chin on Agatha’s mons and makes a show of licking her lips clean.
She greets Agatha with a pleased grin, tilting her head to the side as she purrs, “Good morning, dearest.” Just the sight of Death’s face covered in her blood and looking like a cat who caught a canary is enough to make Agatha shudder with desire, her clit throbbing.
“What are you - Rio!” Agatha yelps, jerking on the bed.
The dark-haired woman finally releases her wrists only to worm them between her legs and use her hands to spread the spirit witch’s labia apart. Spitting onto her hole, Rio watches with a glint in her eyes as it dribbles down into her entrance before ducking her head down to delicately suck her clit in between her lips.
Rio pauses when Agatha hastily grabs a handful of her hair, wrenching her face away. “Wait, I’m - I’m bleeding,” she stammers.
Rio quirks an eyebrow. “Indeed you are.”
“You should stop,” she protests weakly, although in actuality she wants anything but that.
Upon hearing that, Rio cocks her head in the adorable way she does when she is puzzled. “Why?”
Agatha blinks at her, at a loss for words. She eases her hand free from Rio’s grip, and her arm flops down onto the mattress, perpendicular to her body. For the vast majority of people, that would be enough. She has not had many previous lovers, but they never wished to touch her, let alone eat her out, when she was having her period. Agatha was never bothered by it and happily ate out women on their periods, but she has never had a lover willing to return the favor, and they never gave her a reason as to why.
“It - it must taste unpleasant,” she says, for lack of a better explanation.
Rio’s eyes darken into pools of endless cosmos, and she chuckles, the sound a deep low rumble that sends chills down Agatha’s spine. So often she forgets that her charming and seemingly guileless green witch is much, much more than she appears - that she is, in fact, ancient, immortal, and omnipotent.
“You think that the taste of a little blood would deter me? Me, Who Rules Over All Departed, loved, forsaken, and forgotten?” Rio murmurs, planting a kiss on her clit and then on each of her inner thighs, which triggers Agatha to clench her muscles, trembling. Her hands curl into fists, tearing at the sheets beneath her. “I have waded through crimson lakes, the bloodiest battlefields known to humankind. This blood of yours, from your beautiful cunt, is the sweetest I have ever feasted upon. It is proof of your ability to bear fruit, to bring life into this world. As Death, there is nothing I revere more than Life.”
She licks, her tongue making a long, sweeping movement from her perineum, over her slit, and up to her bundle of nerves. Agatha bites her lip hard to muffle her whimpers as her blood sings, her whole body feeling as if it’s thrumming. Her teeth break through her skin with a silent cry when Rio surges forward, kneeling and bracing herself with one arm as she captures Agatha’s lips between her own. Her spare hand takes a firm grasp of the spirit witch’s pubic hair, yanking and stretching her skin upwards until her swollen little pearl is exposed to the cold air, tingling.
The kiss is bruising but no less doting, with Rio’s mouth tasting of sharp metallic iron with the faintest hint of honeyed chocolate from last night. Agatha stares up at her with wide eyes when Rio pulls away, leaving her panting and winded. The cosmic entity peers down at her with aching fondness, and Agatha is reminded once again just how lucky she is to have someone as remarkable and impossible as Rio Vidal, Lady Death, as her partner.
“You like it?” Agatha whispers.
Rio nods with a shaky exhalation. “I would lick every drop from you if I could, to prepare you for your mating.”
Agatha’s brain grinds to a halt. Hearing that singular word emerge from Rio’s mouth is nearly enough to send her tumbling over the edge into a spontaneous orgasm before they have even reached the main event. She feels a rush of liquid between her legs and despite knowing she’s on her period, she knows it’s not blood - it’s her own slick, in response to the thoughts racing through her head right now.
“My - my mating?” she echoes, shocked and so turned on that she might cry.
Agatha gazes up at the ceiling, trying to keep her rapid breathing under control as Rio trails her lips down her body, down the valley between her breasts, which she scrapes her teeth against and dots with blood-stained kisses. “Hmm. My lover is in heat,” Rio growls, the subhuman reverberation in her voice insanely hot.
Wrapping her arms around Agatha’s thighs, she hikes her closer, causing her to bounce on the bed with an exasperated huff. But that annoyance quickly dissipates when Rio dips her fingertips between her folds, swiping up a glob of slick that is pink with her blood and popping the digits into her mouth with an appreciative moan.
“What… what do you mean… by… heat?” Agatha manages to gasp out. “Rio, I - I think you’ve misunderstood.”
She’s barely coherent enough to scrounge a thought together, as Rio splays her dominant hand possessively over her cunt. The green witch’s thumb strums over her little pulsing nub and triggers ripples of intense pleasure that she feels constricting her womb. Surely Rio can’t mean ‘heat’ as in the animal kind of heat? The kind that makes cats yowl and pace the streets, and dogs frantically hump anything with a heartbeat.
Apparently, she does mean heat in that way, because Rio shifts on her knees between Agatha’s legs, sinking into a seated kneeling position as she assures her smugly, “Oh, I haven’t misunderstood at all. You have all the symptoms of heat, and now this delicious nectar between your legs is calling to me, screaming your fertility.”
Taking hold of Agatha’s left calf, she pushes it upwards as she inches closer, until her upper thigh is crammed up against her stomach. It puts delicious pressure on her belly that is only amplified when Rio begins to swirl two fingertips in tight circles around her clit, using the wetness erupting from her hole as lube.
“Is it not my duty as her chosen to ensure that she is bred as her womb demands?” Rio purrs.
The combination of those words, along with Rio thrusting her fore and middle fingers into her cunt and immediately crooking them upwards to graze over her G-sport and her upper walls, has Agatha thrashing wildly.
Rio presses her forearm down on her pelvis to keep her pinned, a feral grin on her face as Agatha howls, “Divine Mother and all that’s holy!” and comes around her fingers.
Come and blood squirts out of her cunt, spraying over the green witch’s hand and onto the sheets. Her pussy mouths at Rio’s fingers hungrily, swallowing them down, and all Agatha can think in that moment is more, want more, need more, need to be full.
“Wrong deity,” Rio laughs, scissoring her fingers apart inside Agatha, which causes her to let out a wheezing groan at the sensation. She bends down to press a gentle kiss on her lover’s smooth stomach. “Good cum, baby?”
Agatha can only nod, utterly overwhelmed as waves of carnal delight wash over her, like the ocean lapping at the shore. It’s official: she definitely has a breeding kink. Rio got her off just with the mere suggestion that she might breed her whilst putting her fingers inside of her.
Agatha has contemplated having children before, of course, as all young women tend to do when they meet their partner, but has never brought it up in conversation with Rio. Her assumption has always been that since the two of them are lesbians, there would be no way for them to conceive a child without fertility magic - and even that would be tricky, since Rio is a cosmic entity and not even human, and Agatha has a nasty instinctual drive to devour all of the magic around her. That doesn’t mean that she hasn’t wondered.
“No more Divine Mother,” Rio orders, withdrawing her fingers, much to Agatha’s disappointment, to caress Agatha’s haunches with her hands. She drags them up and down her sides, pausing only to divert and playfully pluck at her nipples until she whines. “The only name I want to hear from your lips is mine. Your mate, who is going to get you pregnant.”
She sounds so determined, and Agatha respects her dedication and resolve, but there’s one tiny flaw in Rio’s plan. “You’re kind of missing some important anatomy to do that, Rio,” she reminds her.
Rio smirks at her. She crawls forward on her knees until her crotch is pressed directly up against the spirit witch’s cunt - and Agatha freezes, feeling an extremely distinctive, hot, hard length rub up against her slit. “Am I?”
Gaping, Agatha scrambles up onto her elbows and widens her legs to get a glimpse at the miraculous new appendage attached to her lover. It’s a penis, but it’s not one of the ones made of vines or smooth sanded wood that the green witch usually adorns. No, this one is made of flesh and blood and silky skin. She doesn’t have any balls, so it looks more like a hyper-realistic strap than a real dick. To Agatha, it appears as if Rio has somehow used magic to swap her vagina for a cock. It has a slight upward curve to it that Agatha knows will feel amazing inside of her.
Rio bites her lip as she smiles and wiggles her eyebrows, looking far too pleased with herself. “Somebody is staring,” she says in a sing-song voice.
“Can you blame me?” Agatha whispers in awe. “Oh my god, you’re so pretty, darling.”
Rio is rock-hard and erect, the foreskin of her new penis pushed back to expose a flushed pink head, where a bead of translucent precum has emerged from the tip. It’s real fluid, not an illusion, and clearly magical in origin. Agatha can’t resist the urge to reach down and brush her fingers over the length. Rio’s hips buck immediately, her cock bobbing up and down as she chokes out a moan.
“Can you feel my hand on you right now?” Agatha gasps. This is going to completely change the game for them when it comes to sex. (Especially if Agatha can work out how to do this herself.)
Rio squeezes her eyes shut as Agatha strokes her palm along the thick length, tracing the visible veins. Her cock twitches within the spirit witch’s hand, answering her question without Rio needing to give a verbal answer. Yes, she can feel Agatha touching her, and she is remarkably sensitive. Shifting her pelvis, Rio settles the weight of her cock on top of Agatha’s belly, allowing her to examine its size and girth relative to her stomach. Her member leaves a wet trail of precum as it slides upward, the tip just below her belly button.
It’s then that Agatha realizes that Rio is big. Much bigger than anything she has taken before. She tries to curl her fingers around the circumference of her cock and finds that she’s so thick that her middle finger and thumb don’t even touch. And the length of it - god, she would be surprised if it didn’t reach up to her cervix, because it must be at least eight inches.
She wants it inside of her. Immediately.
“Fuck, you’re huge,” she rasps, so aroused that her throat and mouth have completely dried out.
Rio looks momentarily worried, her brow furrowing. “Too huge?”
“I can’t wait to feel you split me open,” Agatha keens, thrusting upwards so that her clit rubs along Rio’s cock, smearing pink-tinged wetness over her.
Rio looks like she’s about to bust just from feeling her rut up against her. Her breathing grows faster as she delicately pets over her lover’s beautifully flushed tip. She catches a drop of precum on her fingers and shoves them into her mouth without hesitation, desperate to taste her. It’s sticky, salty, and musky as it coats her tongue, and if Agatha weren’t half-pinned down by Rio right now, she would tackle her onto her back and deepthroat her.
Instead of that, she gathers more precum, because Rio is pumping it out without abandon now, and fingers herself with it, massaging it into her aching clit and then into her opening, between her folds. Rio’s eyes darken considerably at the sight and she looks as if she wants to snap her up and eat her whole - or fuck her unconscious, which there is a much higher probability of her achieving.
Agatha gulps. “Can you actually cum with your handy dandy magical penis, without testicles?”
Rio nods, smirking. “I plan to. Many, many times, inside of you, if you’ll let me.”
“You can really get me pregnant?” Agatha asks in a shaky voice.
“I don’t know,” Rio admits, uncertainty flitting over her face. But then she leans in and whispers sensually, “Would you like me to try?” as she notches her tip within Agatha’s entrance, using her blood and cum to slick herself up.
“And have a child out of wedlock? What would the churches say?” Agatha tries to joke, but she’s far too focused on Rio’s movements.
“Who gives a fuck about them? As one of the primordial entities, I think my opinion trumps theirs,” Rio quips. “Isn’t the whole human deal with children conceived out of wedlock that the parents quickly elope to avoid their reputations being tarnished?” She leans in to theatrically whisper, “I’m Death itself and you’re the siphon witch who killed her own coven. I think our reputations are unsalvageable by this point, but if you want to elope, I wouldn’t be opposed.” And then she adds, with a toothy grin, “Fuck the churches.”
The teasing, of Rio running the head of her cock in between the spirit witch’s folds, pushing half an inch in and out of her hole and then pulling out to caress her clit, sets off some sort of primal switch in Agatha’s brain. That, blended together with the fact that Rio just essentially asked her to marry her in some strange roundabout way, is enough to make it so she is on the cusp of pleading; she doesn’t just want Rio inside her now - she needs her.
Her hips spontaneously lift up off the bed, jerking. “If that’s your way of proposing to me, then you better knock me up today, or the handfasting is off,” she croaks.
“You want that?” Rio questions, her expression morphing into one of sheer conviction. “You want me to breed you?”
She claws at her lover’s breasts, scratching deep score marks into her skin as she tries to close her legs around her waist and lock her ankles to hold her in place. But Rio resists, and is much stronger; she abandons holding her cock, leaving the tip parting her cunt lips, so she can use her hands to securely grasp Agatha’s legs - and then she pushes them upwards, until she’s trapped in a mating press.
She goes fucking feral, whimpering and moaning like the horny bitch in heat that Rio thinks she is. And oh, is Agatha so delighted that she gets to play into that role. “Fuck, yes. Do it, breed me, put a baby in me,” she begs, tossing her head back to bare her throat.
“I’ll do my very best,” Rio tells her, her eyes wild and voice ragged. Her hips keep twitching forward and back, and Agatha genuinely thinks that she might go crazy, because she can feel the head of Rio’s stiff cock lazily slipping in and out of her entrance, never quite penetrating her. “Hold your legs in place, sweetheart.”
Agatha does so instantly, wrapping her arms around them. Now Rio’s hands are free, she uses them to tenderly spread the spirit witch’s vulva around her lip, and just the feeling of Rio’s rough fingerpads so close to her clit makes her want to scream. The green witch groans as she stares down at her, and even though Agatha’s head is tilted back, her eyes closed, she knows what she’s admiring. She’s watching herself sliding her cock head in and out of Agatha’s hungry hole; her cunt is randomly clenching, trying to clasp at the couple of centimeters that Rio is teasing her with to entice her to mount and fill her.
“I’m going to keep you chained to this bed, to my side, all day,” Rio threatens, her thumb flicking Agatha’s clit from side to side, the stinging flashes of pleasure making her cry out as her nerves are set aflame. “You’re going to be stuffed so full of me by the end of it that my semen will be dripping out of you for the next week.”
Oh god oh god oh god, Agatha chants mentally, but her mouth is agape as she heaves for oxygen, feeling very much like she might actually combust if Rio does not get inside her this very next minute.
“Made this cock just for you, Agatha, the perfect size to stretch you out and keep you plugged up with my cum. Would you like that? To be Death’s breeding bitch?” With those two final words, Rio pinches her clit between her fingers, hard, and twists.
“Fuck,” Agatha screams, and her orgasm crashes over her like a tsunami.
For a fleeting second, she is actually concerned that her magic, bubbling inside her in response to her lover’s proximity and rising adrenaline, might explode out of her in a fiery eruption of purple.
Her hands, clutching handfuls of the sheets, maul them to pieces as she flails wildly beneath Rio’s body, wailing breathlessly, “Yes, yes, make me your breeding bitch, turn me into your whore!”
“Gladly,” Rio snarls, and then she impales Agatha to the hilt with her cock in a singular, powerful thrust.
Judging by Agatha’s wanton begging and whining, and her eagerness to have Rio’s cock inside of her, the green witch is wholly confident that her lover’s heat is well underway. She’s super sensitive and responsive, having already cum twice, and she is radiating heat, her entire body flushed.
Rio watches in abject wonder as Agatha’s cunt lips, soaked with blood-tinged slick and beautifully pink and puffy, turn bone wide as the skin stretches around her bulbous cock head; her folds drag around Rio’s length as she thrusts up into her in one smooth stroke. The minimal prep Rio has done, in the form of eating her out and then fingering her, has gotten Agatha so wet that Rio bottoms out without any resistance at all.
She has fucked Agatha with enchanted straps before, which has felt incredible, but nothing compared to the feeling of sinking her own flesh and blood cock into her lover’s cunt. Her walls clutch at her, hot and pulsing as if attempting to milk her. Rio’s vision goes completely white for a moment and she feels like she’s about to pass out, her breath catching in her throat. She has been somewhat indifferent towards the mating press position in sex before, but now, she thinks it might be her new favorite.
Seeing Agatha so overwhelmed that she’s fallen completely limp, her throat exposed, makes her growl possessively. “Fuck, you’re tight, Agatha. Am I stretching you out good, baby?” she croons.
Agatha’s eyes are squeezed closed, her mouth hanging open as she pants, but she swiftly nods, a mewl tearing from her mouth. Remaining fully jilted inside of her, Rio grinds forward, so that her pelvis stimulates Agatha’s flit. Her cock is instantly flooded with liquid warmth and she chokes, her hips stuttering and forcing her deeper inside of the spirit witch’s core.
“You feel amazing,” she stutters. Withdrawing a few inches and then sliding back in until her cock is fully enveloped in Agatha’s heat, she groans. “You’re drenched, you’re so desperate for my cum.”
“Yes, I want it, give it to me,” Agatha begs in a slurred voice, her blue eyes dark with desire but clouded from overstimulation.
Rio starts slow, wanting to give her lover time to adjust to her size before she fucks her until she can’t breathe. That, and she wants to savor the feeling of Agatha’s cunt clasping at her cock. She lowers her torso, bracing her hands on either side of Agatha’s waist and balancing carefully as she smothers the spirit witch’s body with her own; remaining sheathed, she grinds gently deep inside of her, so that the tip of her cock tenderly massages her cervix. Agatha continues to hold her legs up and open for Rio, so that she can rut into her unimpeded.
Cloying high-pitched noises wrench free from Agatha’s mouth that the green witch silences by drawing her into a long, drawn-out kiss. A particularly forceful thrust on Rio’s part triggers her mate’s mouth to fall lax, which allows Rio’s tongue entrance. She kisses her thoroughly, in the way that she knows triggers Agatha’s toes to curl, only breaking it off when she senses that her lover needs to inhale oxygen. What a pesky thing it is, breathing.
As Agatha labors for breath, Rio trails her lips down her neck, nibbling and sucking to leave a chain of love bites. When she reaches Agatha’s breasts, she sinks her teeth into the meat of her right tit and delights in the manner by which Agatha jerks beneath her, her cunt clenching like a vice around her cock.
“My greedy bitch in heat,” Rio murmurs, extending a hand down to stroke over that delicate inflamed pink pearl that now protrudes from its hood and Agatha’s drenched folds because of the thickness of her dick pushing it up. “Such a good girl, signaling to me that you were ready for breeding by making your cunt all hot and wet, luring me in as your mate.”
Her dirty talk is making Agatha squirm and whine, which is the whole reason Rio is trying to be as vulgar and provocative as possible. The younger woman releases her legs to wrap her arms around Rio’s back and rakes her nails down her spine. Her nails are clipped, but still long and sharp enough to scratch her, creating a mild burning sensation.
Rio shivers. Pain is something she is still not quite accustomed to; she turned on all of her body’s receptors for it when she first learned that Agatha has a pain kink and enjoys rough, almost violent sex. Agatha demanded that she make herself feel it when she ran Death’s scythe blade over her pale belly to carve out her name and stuffed her fist into her cunt. Rio loved the synergistic mixture of pain and pleasure so much that she’s never switched those receptors back off since.
Sensing that Agatha is not just ready for more, but desperate to be fucked harder, Rio straightens back up to widen the stance of her knees. She uses her thumbs to spread out Agatha’s stretched slit around the meat of her cock, just to ensure there’s not too much friction, and then very slowly pulls out, until just the first inch of her is inside. The spirit witch whimpers, her legs seizing and tears in her eyes as she’s left empty.
Agatha’s copious bloodied slick has soaked the two of them, and Rio hisses as she jerks off Agatha’s clit using it as lube, spitting down onto where they are joined together for good measure. And then, making strong eye contact with Agatha, who is watching her with glazed-over eyes as round as plates, she shoves forward to fill her cunt to the brim.
“MINE,” Rio thunders possessively. “My cunt to fuck, to impregnate. My womb to stuff full of my babies. My mate.”
“Ohfuckohfuckohfuck,” Agatha babbles under her breath, her whole body shaking. “Mate me, make me yours, claim me so that nobody else will ever dare to touch me, Rio!”
“My dirty girl in heat, with her hungry pussy,” Rio carries on, grunting as she speeds up her thrusts, setting a punishing rhythm that she matches with swipes of her thumb over Agatha’s clit so that she cries out needily with each lunge of her cock. Her cunt spasms uncontrollably around Rio, which only makes her jab her shaft inside of her with more ferocity, so she can feel it enclasp her. “This is what you wanted, isn’t it? You wanted my dick inside of you. Fuck, I can feel you clamping around my cock. I could stay inside you forever.”
Agatha nods vehemently, her head lolling back against the pillow as she breathes out hoarsely, “Do it. Keep me chained to your lap, wear me like a cocksleeve, use me to keep you warm. Carry me around with you as you reap souls so that the entire universe sees and understands that I belong to you.”
That’s insanely hot, and Rio’s arousal ramps up to inhuman levels so that she feels ablaze, her magic sparking and quaking inside of her, begging to be unleashed. Rio hastily squashes it down. It may be her green magic, rather than her death magic, but nothing could possibly be more dangerous than Death herself losing control. And it would definitely be dangerous for her to lose control whilst she’s fucking Agatha.
She funnels her arousal into pumping out more pheromones for Agatha to drink in from the air and strengthening her thrusts. They have become so powerful that Agatha would be migrating up the bed if Rio weren’t keeping her half-pinned in place by grabbing her thighs and yanking her harshly down onto her dick.
Agatha’s fallen silent, face creased with concentration and mouth forming an ‘O’ as she rocks into Rio’s thrusts, her pulse visibly fluttering in her throat. The tension in her expression suggests she is utterly stunned by what is happening, and doesn’t know how to process how overloaded she feels. But it also makes her look as if she’s in pain, and it’s then that Rio realizes, as she glances down to quickly check that she’s not hurting her lover, that she can see a slight bulge beneath Agatha’s abdomen every time she ruts forward.
She’s so shocked that she’s left speechless for a moment, and she zeroes her gaze in on Agatha’s stomach to watch, awestruck, as that bump appears with every stroke of her cock inside Agatha’s cunt. Rio places one of her hands over the spot, and releases a moan when she not only feels the distension beneath her palm, but also experiences the pressure of her hand along her length. She has never thought of Agatha as small, but she remembers how her cock reached up to her belly button when she laid it out on top of her earlier to let Agatha admire her new appendage.
“I’m so big I can see my cock inside your belly,” she chuffs raggedly.
Agatha’s eyes flash open and she gasps out, “What?” She peers down and watches with scrutinizing eyes as Rio plunges in and out of her pussy. When she spots the bulge in her stomach when Rio hilts inside of her, her cheeks turn bright red, the blush propagating down her chest. “Ohmygod you’re so big inside of me, fuck, give me more, Rio, make yourself bigger!” she pleads.
“More?” Rio repeats, astonished. She can do it, of course - her cock is constructed entirely of magic, and so she can increase the size and girth of it with merely a thought and a flicker of green magic. But she’s concerned that it might be too much for her lover, even though she’s begging for it. She doesn’t want to tear her. “Agatha, I -”
“Please, god, please, more, stretch me until I’m fucking bursting, make me take it, bruise my cunt so much that I can’t walk straight tomorrow!” Agatha howls.
“I don’t want to hurt you,” she says, hesitating.
Agatha jolts up and snatches a handful of Rio’s hair in her fist, jerking her head down. “Be a good fucking boy and make your dick bigger when your mistress asks,” she snarls, slipping into her dominant voice as she locks her legs around Rio’s waist, forcing her to stay hilted. “You do it right now or you won’t be getting your cock wet again until I think you have sufficiently made it up to me, and you know how much I love to make you suffer.”
It’s a stark reminder of the fact that Rio is usually the one on her back with Agatha strapping her down, and that getting to top the spirit witch is typically a treat for her, one she has to earn with good behavior and following orders. Rio might be on top today… but Agatha is ultimately always going to be the one who holds her leash.
Rio nods hurriedly with a tiny whimper, and shutting eyes, focuses her magic on her cock, encased in the warmth of her lover’s cunt. She feels it gradually grow as she adds another inch to her length and then another half to her girth as well for good measure, not wanting Agatha to be disappointed. She must be able to feel it get longer and thicker inside of her because Agatha gurgles, eyes rolling back in her head as she falls back, releasing Rio’s hair. She grabs at the sheets and strains upwards, pushing down until Rio’s cock bottoms out inside of her - and creates an even larger visible protrusion within her abdomen.
“So big,” Agatha mumbles dreamily.
“Yeah?” Rio pants, struggling to hold still because now she is bigger, Agatha feels even tighter around her, and she is seriously struggling not to cum. “You like it big?”
“I love it,” she groans. “I love my good boy with her big fat cock that’s gonna fill me with seed and knock me up. Fuck me, Rio, fuck me so hard that you mold my pussy until it’s a perfect fit for just you.”
It’s all the permission she needs. Rio surges forward, catching Agatha’s legs from beneath her knees and hovering over her; she settles into position so that her hands are planted by her lover’s waist, legs spread to open her cunt wider, and she has free rein to thrust using the entire weight of her body. And then she begins, drilling into Agatha with brutal pace and force until her pussy is literally squirting out blood-tainted juices with every savage drive of her hips.
This carries on for the next ten minutes, Rio fucking the shit out of her mate so that she will absolutely be so sore that she will struggle to walk properly tomorrow. It gets to the point where Agatha is so drunk on her cock that she is wheezing and drolling, tossing her head from side to side. Mini orgasms crash over her over and over again as Rio slams into her G-spot, leaking thick precum into her cunt that just like her pheromones, is full of aphrodisiac chemicals to drive her feral with desire.
This is what Agatha needs during her heat - to be rigorously fucked to exhaustion. But currently, her adrenalin is high enough, circulating through her arteries and veins, that she is nowhere near tired. In fact, she’s starting to fight, wriggling from side to side and trying to raise her butt up so that Rio sinks even deeper into her, even though there’s no way that she can when she’s already striking her cervix with every thrust - unless Agatha is attempting to get her to break through her cervix to directly fuck into her womb, which is both a terrifying and electrifying idea.
Eventually, Rio begins to get frustrated with Agatha’s writhing, especially when it actually causes the head of her cock to slip free of her cunt at one point, which of course immediately causes the spirit witch to start wailing as if she’s being tortured, and not just… not being fucked how she likes.
She slaps her hand down onto Agatha’s thigh, leaving a red handprint behind. Agatha groans and then chokes on it when Rio stabs her cock into her aggressively until her tip prods her G-spot, grinding deep. “Stop squirming and trying to escape,” she growls, snagging hold of Agatha’s hands and pinning them to her sides. “You take what I give you. Lie still like a good breeding bitch. Don’t make me use force.”
Her order has the opposite effect, because instead of submitting and falling still, Agatha’s hips buck frantically, to the point where she’s practically riding her cock despite her supine position.
“Oh god, do it!” Agatha cries out.
Rio’s mind goes blank. “Use force?”
“Fucking force me to take you. Treat me like we’re both wolves and you’re having to restrain me to get me pregnant with your pups!” Agatha demands.
Wolves? Well, Rio knows the perfect position for that. She holds her breath as she pulls out, wincing at the sudden coolness her dick experiences now it is no longer sheathed inside Agatha’s hot walls. Agatha immediately puts up a fuss, whining for her to get back inside her - but then she promptly shuts up when Rio snarls fiercely in her face like an animal, aiming to intimidate her.
Rio wraps one hand around her cock, stroking herself for a minute to take the edge off, and then flips Agatha onto her stomach. The spirit witch squeaks as she’s twisted over onto the mattress and lays starfished; she obediently lifts her hips when Rio pats her ass so that the green witch can slide two pillows beneath her pelvis to support her.
Rio clambers into position, knees bracketing Agatha’s legs and the head of her cock pressed into Agatha’s weeping entrance. Agatha arches her back to raise her hindquarters receptively, chuffing. Hunching over Agatha’s back as if she’s a wolf mounting her mate, Rio lets out a guttural noise and slams her cock into Agatha’s heat-swollen cunt.
As she bottoms out, Agatha lets loose a screech of, “Yes, YES, RIO!” which transforms into a strangled moan when Rio wraps a hand around her throat, squeezes, and roars, “QUIET!”
Once Agatha lapses into silence, the only sounds now bursting from her lips being muffled grunts, Rio lets go and starts to thrust, rather gently at first. She has another focus right now. Rio sweeps Agatha’s messy, tangled hair away from her sweat-soaked back over her shoulder, to expose the back of her neck. Lowering herself so her breasts press up against Agatha’s spine, Rio tilts her head and licks her lips, examining her lover’s neck for the correct spot.
Once she’s identified it, the equivalent of where Agatha’s scruff would be if she were a wolf, Rio grins, exposing her canine teeth that due to a surge of magic might be a little too sharp for a human’s, and clamps them down on the back of Agatha’s neck, to pin her in place.
Agatha’s whole body quivers. “Fuckfuckfuckfuckfuck,” she whispers, her voice muted by how she’s buried her face in her pillow. “That’s it, good boy, fucking take me.”
Rio bites down harder, a threatening growl rumbling from her chest as she spears her cock into her mate with such viciousness that it shakes the bed. Agatha’s words disappear into unintelligible and hysterical whimpers. Rio keeps her pinned down like this, her teeth sunken into Agatha’s neck skin, for several minutes as she fucks her, until her jaw begins to ache. When she lets go, Agatha remains boneless beneath her, having got the message to stay still and not squirm anymore.
Satisfied, Rio pinches and spreads Agatha’s asscheeks to expose that clenched winking hole that she has fantasized about breaking in. It would feel even better with her real cock. Not tonight, but someday, she muses.
The green witch’s eyes drift down and she hums in delight at the sight of her dick sliding frictionlessly in and out of her mate, a ring of white foam around the base and blood caking the shaft. Seeing the white cream instinctively makes her start rutting harder and faster, her arousal spiking, and her desire to fill Agatha with her own fresh white cum becoming overpowering.
Her cock begins to throb, her belly tightening. “I’m getting close,” she gasps out a gruff warning.
“Me too,” Agatha tells her in a coarse rasp. And then, in a frenzied, longing voice, begs, “Cum inside me.”
Oh god oh god oh god, Rio chants in her head, not even caring that she doesn’t believe in such deities because she technically is one herself. Rio places her hands on Agatha’s hips, to pin her to the mattress, escalating her thrusting. She riles herself up as she pants, “Yeah, you want that? You want me to put my babies inside you? You want your mate to knock you up?”
Agatha cants her hindquarters back desperately, reaching around with trembling hands to do what Rio just did, pulling her asscheeks apart so that she can better plow her ginormous cock into her cunt. “YES, yes, god, pump me full of your seed! Breed me!” Agatha cries.
“Cumslut,” Rio snarls, grasping the spirit witch’s waist tightly as she deepens her thrusts, hoping that she might be able to bully the tip of her cock into Agatha’s cervical opening. “You want me to cum inside you so bad… I’m gonna fuck you so full of my seed that you look pregnant.”
“OhmyfuckinggodYESMYLOVE.”
Agatha orgasms like a geyser, squirting around Rio’s cock. She pisses out her cum and period blood all over the mattress as she screams incoherently, thrashing. Rio rams into Agatha one last time before she feels the tension in her abdomen release, blacking out for a fleeting second with stars exploding in her eyes as semen spurts from her cock, hot white ropes firing out of her tip and pouring into Agatha’s pussy. It’s euphoric, exhilarating, the climax of all climaxes.
She groans, her hips spasming in sharp thrusts as she tries to shove her cum deeper. She rubs her cock head against her mate’s cervix to coat it in her seed, Agatha’s convulsing walls squeezing more out of her even when she thinks she might be done.
When her cock finally stops, Rio collapses onto Agatha’s back like a weighted blanket, out of breath and completely astonished. She knows she doesn’t normally have a cock, but she honestly doesn’t think she has ever cum so hard in her life. And Agatha has made her cum plenty of times before, so it’s not as if there’s a small sample size.
Agatha can’t seem to stop whimpering, and when Rio raises her head to check on her, she sees that she’s turned her head to the side on the pillow, and there are tears in her eyes. She bolts upright in concern, but then she spots the tremulous, adoring smile on her lover’s face, full of love, happiness, and pure joy, and her black heart skips a beat. Agatha’s soul, illuminated in lilac and beautifully complex, is vibrating with elation.
“I can feel it,” Agatha whispers, beaming at her. “I can feel your seed inside of me. God, it feels incredible, Rio.” She rocks back, and Rio’s cock sinks maybe a quarter of an inch deeper into her cunt. “Fuck, I don’t think I have ever felt this full in my life.”
“S’not over yet, sweetheart,” Rio tells her with a purr, running her hands up along her lover’s spine. She has no plans to pull out or stop anytime soon. “That’s one load, but I think we can manage a few more during your heat, don’t you?”
Agatha laughs at her, a gleeful sound, and her eyes shine with mirth. It’s almost as if she knows something that Rio doesn’t. She cautiously rolls over to return to lying on her back, refusing to allow Rio’s cock to slip out of her. She pulls the green witch closer with her ankles on her buttocks so she remains hilted.
“I gathered that from the way you’re still hard as a rock inside of me.” She bites her lip, and then whispers with a lewd smile, “Pull out for a moment. I want to see you dripping out of me. I wanna see how much cum you pumped inside of me.”
That is something that Rio also suddenly is hungry to seed and so very carefully, she grasps the base of her cock and withdraws it from Agatha’s tight, still pulsing slit. Her pussy lips are red raw and inflamed from the intense fucking, but her hole itself remains stretched open. The thickness of her cock has ensured that her cunt will take several days to tighten back up, bedside right now, she reckons that she could probably fit at least two fingertips without much effort.
Rio finally pulls the tip of her length free, and it emerges with a pop. She grasps it within her fist as it bobs upwards and bounces off her abdomen, still erect and smothered with a combination of their juices.
Agatha raises her knees and plants her feet on the mattress, spreading her thighs so that her drenched cunt is spread open. There’s no sign of Rio’s cum for a moment, just the faintest trickle of slick and blood from Agatha’s drooling entrance. Agatha lifts herself up onto her elbows, beady eyes fixed on her cunt as Rio watches, just as spellbound, slowly jacking off her slickened dick in her palm.
Finally, after what seems like an age, a gleaming bead of white appears within Agatha’s hole. It gloops out and down her perineum as a thick creamy rope. Rio’s breath catches in her chest and she feels her eyes start to become wet. That’s her. That’s her, inside Agatha. Her cum. She’s both brought to tears, and instantly raring to go once again, her passion reignited by proof that she has bred her partner whilst she’s in heat, as a good mate should.
Agatha immediately swipes the cum up with her fingers and shoves them into her mouth, rubbing the semen over her tongue. “Delicious,” she murmurs, her eyes hooded.
She presses down on her lower belly, and more seed begins to dribble out of her cunt. Rio curls her lip at the sight and before she understands what she’s doing, she’s using the head of her cock in her hand to collect all of the spilled semen and pushing it back inside of Agatha by plowing back into her pussy, like a hot knife through butter.
Agatha gasps, her eyes wide, and she immediately grabs at Rio’s shoulders when a glimmer of green magic swirls below, thickening the cosmic being’s shaft another half an inch.
“Don’t want all my good work to go to waste,” Rio growls. “You let it out of you and I’m gonna have to fuck it back in.”
“You could use a spell,” Agatha suggests, tongue darting out to wet her dry lips. “You could put a seal over my cunt… so that nothing can escape. You could use me as many times as you’d like and never let a single drop out of me.”
“What’s the fun in that when I can just keep you plugged up with my cock?” Rio grins. “Gotta make sure my seed takes.”
Agatha’s pupils dilate with desire, turning them black. “Fuck me again,” she orders. “And don’t stop until I safeword. Do you understand?”
“Yes, Mistress,” Rio purrs, with an experimental, teasing thrust. “I live to serve my mate during her heat.”
“No more talking,” Agatha says, clenching her cunt muscles around Rio’s cock, clearly on purpose, to hear her mewl. “My mate doesn’t need words when she’s already proven she acts like a beast when breeding me.” When Rio releases a thunderous snarl, Agatha smirks. “That’s my good boy.”
They fuck like animals for the rest of the day. Agatha’s stamina is tremendous for someone in heat, and she doesn’t blanch once at any of the positions Rio maneuvers her into: missionary with her legs over Rio’s shoulders; the position that Agatha affectionately calls ‘cowgirl’ where Rio allows her, for a single orgasm, to sit atop her; that same position in reverse whilst edging her; at one point, they even fuck standing, Rio cradling Agatha to her chest with her legs around her waist as she drives her cock into her until Agatha is practically delirious.
The spirit witch has remained as ravenous as ever as she’s filled her over and over again with cum, until it’s spilling out of her in rivulets of white, her pussy brimming with Rio’s spend. Her pussy lips are swollen to the point that they essentially close up and plug herself whenever Rio briefly pulls out of her. And when it does splutter out of her, Agatha desperately gathers the seed on her fingers and tries to stuff it back inside herself. She even stoppers her pussy with three fingers up to her knuckles while Rio changes their position, so that her cum doesn’t escape.
When Rio comes for the third time, and Agatha for the seventh, she rolls her onto her back so she can eat her out. She’s intrigued to know what she tastes like, but even more interested to know what they taste like together. She eagerly laps up their mixed cum and Agatha’s menses, prying her cunt open with her fingers so that she can admire Agatha’s raw, red passage painted white - and then she sticks her tongue inside, giving her a brief cleaning before she fucks her full of cum again.
A small bump has gradually appeared in Agatha’s abdomen as Rio has continued to pump her full of semen, making her look a couple of months pregnant, but it’s not a baby currently inside her. It’s Rio’s cum, plugged inside of her by her mate’s giant cock, that Agatha has begged her over the past few hours to increase in size so that what is essentially a watertight seal has formed between Rio’s cock and Agatha’s cunt.
Rio isn’t entirely sure how long their sexual marathon lasts, but by the time Agatha is about to hit double digits in orgasms and Rio is ready to cum for the fifth time, it’s nearing dusk.
She’s sitting up with her back against the bed’s headboard, feeling drained and fatigued, which is honestly a feat in itself for Death. Agatha is riding her cock - well, riding is too active a word. She’s seated on Rio’s lap, slumped onto her chest with her face buried in her shoulder, grinding down onto her length whilst warming her as they desperately try for one last orgasm.
Agatha is completely wrung out, practically half-asleep in Rio’s arms. The green witch gazes at her softly, stroking one hand up and down her spine soothingly, playing with the curly ends of her sweaty hair.
“Clit,” Agatha slurs, a one-worded order.
Rio wiggles her hand, which she is fairly certain will cramp up tomorrow or perhaps will develop carpal tunnel, between their bodies. It only takes three of the lightest caresses of her fingers over Agatha’s red, swollen little button before she’s cumming. It’s the smallest orgasm of the day, her cunt barely twitching. Oversensitive and nearly chaffed after a solid twelve hours of constant sex, Rio’s cock manages one last hurrah in the form of weakly ejecting a stream of thin semen before stopping.
“Azaleas,” Agatha croaks, her voice worn out and barely audible after screaming for hours on end.
It’s their safeword. Agatha is done. Rio nods in agreement, partially relieved because despite her cosmic stamina, she is also beginning to flag. “Azaleas,” she says, in an equally gravelly voice.
She cradles her lover in an affectionate embrace, knowing that what Agatha will crave most after today is intimacy without sex. Hopefully, the fact that she’s been fucked to exhaustion means that her heat will have broken.
“Don’t pull out,” Agatha implores, sighing into Rio’s collarbone as she relaxes. Rio’s chest is covered in teeth marks and hickeys. “Wanna fall asleep with you inside me. Keep me full.”
“Isn’t… there a risk of getting some kind of bladder infection if -“
“You’re Death, love, and a green witch,” Agatha mumbles. “Just do whatever you need to, to stop that from happening. Because if you pull out of me right now I might never let you inside me ever again.”
Rio doubts that’s true, but it’s cute that Agatha thinks that she will believe that threat. She traces a green rune over their stomachs that she has used to cleanse wounds before, not that she needs to do that much when her saliva has healing properties. A tingling sensation rushes through her body, so she assumes the same must happen with Agatha. She briefly worries that it will banish her semen from Agatha’s womb, but it fortunately doesn’t, making her cunt feel ridiculously wet, almost sloshy.
Before they sleep, Rio summons fresh apple juice and bread smothered with blackberry jam to the bed, feeding Agatha small bites and sips. They haven’t consumed anything all day apart from each other's sex fluids, and Agatha has been sweating profusely and bleeding, so needs to replace what water she’s lost. Rio even eats and drinks herself, even though she technically doesn’t need to, because she feels depleted of energy.
Vanishing the dirty plates and glasses, Rio uses a spell to clean the sheets - for what must be the fifth time today - before easing them down. She lies on her back with Agatha atop her, blanketing her, with her now soft cock buried inside of her. Drawing the blankets up over their sore, bruised naked forms, Rio gently turns Agatha’s face towards hers for one last lazy, fatigued kiss.
“I love you,” Agatha says simply. “And I can’t wait to have your baby.”
Time stands still for a moment. Rio is stunned silent. They have said I love you to each other before, but it’s an uncommon occasion, because Agatha is allergic to emotion and affection after being abused and hated throughout her childhood, taught that she didn’t deserve to be cared for. Rio has tried to change her perception of all of that whilst learning about love herself, and it’s been a difficult road. For Agatha to say it so casually is monumental.
And even more staggering than that is that second testament. That Agatha wants to have her baby. They leaned extremely heavily into the breeding kink that both she and Agatha apparently have during their sex marathon today, but Rio was under the assumption that Agatha’s desire to get pregnant was merely something induced by her heat. Something momentary, that would only last so long as her short fertile period would.
But no. It sounds like Agatha does genuinely, actually want to bear Rio’s children. Her shriveled, exhausted cock throbs and aches. Her belly flutters, with butterflies this time rather than arousal.
“You…” she swallows. “You’re being serious?”
“Yes, that is something I am capable of,” Agatha chuckles. “Albeit somewhat rarely.” She sobers when Rio stares at her wordlessly. “When you said that you didn’t know if you could get me pregnant today, were you telling the truth?”
“Of course.”
“So there is a chance.”
She gulps. “I suppose there might be,” she confesses. “As I said - I’m not sure. This -“ She shifts her hips, jostling her cock tucked away warm and safe inside Agatha’s cunt, “Wasn’t exactly planned. Kinda magicked it up spontaneously once I realized that you’re in heat.”
A mischievous grin extends across Agatha’s face. “About that…” she hums. “Humans don’t have heats, Rio.”
Rio blinks. “… I'm sorry?”
“The menstrual cycle… It's not like an estrous cycle. We do have a fertile window where our ovaries release an egg, but it’s not as sexually intense. And the bleeding, and all my other ‘heat symptoms’ - they’re not symptoms of heat, or my fertile period. They’re symptoms of me coming out of it,” Agatha explains to her, with a fond smile. “The blood, it’s the broken down tissue from the lining of my womb. After an ovary releases an egg, it migrates down the fallopian tubes and enters the womb. If it’s not fertilized, then the lining that builds up in preparation for a potential pregnancy begins to break down. Hence the bleeding.”
Rio stares at her blankly. Oh. “… That’s why you said it’s your womb punishing you for not reproducing. Because it’s the tissues that built up for pregnancy being expelled, because you didn’t get pregnant.”
“Precisely.”
“So you… you can’t get pregnant whilst you are bleeding.”
“Cycles vary, so it is possible, but mine is fairly regular, so it’s extremely unlikely.”
She smacks a hand to her face, burning with embarrassment. “And let me guess, you just decided to let me think that you were in heat because you wanted to get fucked til’ the point of exhaustion?”
“You were so dedicated to your mission,” Agatha chuckles. “Who was I to interrupt? I didn’t want to risk killing the mood.”
“I’m dumb.”
“No, you’re not,” Agatha scolds, kissing her nose. “You were just uninformed. And how would you know? You’re new to humanity, and oh so innocent and aware of our flaws and weaknesses. It was a lack of education, not ignorance or dimness. And now, you know. Although…” She brushes her lips over Rio’s jaw. “You were certainly very helpful today. I tend to get horrible cramps when I have my monthlies and you fucked me so well that I’ve barely suffered any at all. And we can roleplay that I’m in heat and you’re my dutiful mate who wants to breed me whenever you want, because it’s hot as fuck.”
Rio tilts her head and murmurs, “I think we can arrange that.”
Agatha’s jaw cracks in a long yawn, and she tucks her head back into the crook of Rio’s neck, nestling down. “‘M so tired I could sleep for a week,” she mutters. “Fuck, I’m gonna be so sore tomorrow.”
“S’what you wanted, right?”
“If it wouldn’t get me strung up and killed I would fly over to Salen and parade around naked to show everybody how bruised and battered you’ve left me after such a thorough breeding.”
Rio’s cock jumps inside of Agatha, and it actually hurts, making her groan. “Please don’t start. I don’t think I could survive another orgasm.”
“My big boy all tired out?” Agatha coos, laving one of the blossoming hickies she left on Rio’s throat earlier with her tongue. “Let’s get some sleep and then you can try again in the morning.”
“In the morning?” Rio parrots, confused.
“Oh, did I not mention? The bleeding part of my cycle… it lasts a week. And you are going to fuck me every single day of it with this special new toy of yours.” She squeezes her cunt around Rio’s cock several times, as if attempting to milk her, which triggers Rio to whimper at the overstimulation. “What do you think, darling? You up for the challenge?”
Rio plants a kiss on the crown of her lover’s head. “Only if you marry me like you agreed to.”
At first, Agatha does not respond, and the green witch worries that she may have frightened her with talk of marriage, or that she may have fallen asleep. But then Agatha murmurs, in a husky whisper, “I heard rumors in the market the other day from some other witches I was scouting out for a meal that they divined a supermoon next month. It’ll be a time of magical amplification and spiritual connection. We should handfast then. It’ll lend great power to the soul-bonding ritual.”
“You -” Rio tightens her arms around Agatha, her heart racing and mind reeling. “You’d tie your soul to me eternally?”
“Well, we’re already mates, right?” Agatha murmurs. “Might as well make sure we’re soulmates too.”
A handfasting would secure their marriage, but performing the soul-bonding ritual would secure their love in the eyes of the Triple Goddess, all forces of nature, and all powers of the universe. They would be linked together for the rest of time, in Life and in Death, with an unbreakable bond that would irreversibly meld their minds and souls together. And since Rio is cosmic, Agatha would be latching herself to an immortal.
Rio has dreamt about the ritual before, but has never been brave enough to bring it up to Agatha, terrified that it would be too soon, since they have only been together for half a year. But she is certain beyond doubt that Agatha is and will be the only person that she will ever truly love, and Rio wants nothing more than to prove to Agatha that she will stay by her side, stand by her forever, and never leave, in a more meaningful way than just words. And a soul-bonding ritual is the most demonstrative way she could show her commitment to their relationship.
The fact that Agatha is the one to suggest they go through with it is enormous and makes her all the more excited.
Agatha is still talking, seemingly unaware of the mental spiral she has tripped Rio into. It’s a miracle that she doesn’t appear to notice Rio’s cock pulsing inside of her, desperately trying to get hard again but failing. “We’ve gotta tie the knot if we’re truly serious about trying for a baby. I’d want them to carry both of our names. Harkness-Vidal sounds nice, don’t you think?”
Rio swallows and tries to center herself, joking, “Vidal-Harkness sounds better.”
Agatha laughs sleepily, her fingers skimming the green witch’s collarbones. “Oh, no, if I’m the one who’s doing all the work for nine months then my name’s going to be first. I’m not bearing Death’s child only for the Harkness name to come second to a surname that you made up on the spot when you gay panicked during our first conversation. Harkness-Vidal, and that’s non-negotiable.”
“As you wish, my love,” Rio whispers, holding her closer.
They succumb to exhausted slumber entangled, connected together by Rio hilted inside of Agatha, snug and cozy. The sun sets and paints the sky with swathes of star-scattered midnight blue and a rich purple that matches Agatha’s magic and soul, a good omen for what is yet to come in their lives.
