Chapter 1 - More Bitches More Knottin

It isn’t until the next day that the pair manage to do anything other than rut like beasts in mating season in Koneko’s room, both with Rias repeatedly being knotted in breeding attempts and several extremely enjoyable blowjobs. Enjoyable blowjobs for both parties, with several knottings out of the way Koneko can enjoy them far more than she was beforehand and Rias seems to enjoy them more and more as they go as well, licking her lips hungrily after two of them.

Admittedly, that ‘something else’ still involves Koneko’s hips slapping into Rias’ hips while she tries to read a book held in place by Rias’ gloriously jiggling tits propping the two sides up. It is… less successful than they would like, though not because anyone’s wandered in and they’ve had to cover up… Koneko frankly doesn’t care if any of the servants of the manor walk in, they’re loyal to the family and won’t say anything so the secret is still safe for now, and they’ve wandered in while Rias was a much more active participant than fucktoy and bookrest and Rias hadn’t stopped for any longer than necessary to answer any questions they might ask her.

No, the reason they were making such little progress was that they were having some genuine issues finding information about Nekomata as a whole, and Nekoshou in particular. At least, in terms of sexual habits and weird biology factoids. There’s plenty of useful other kinds of information about Devils, devil styled magics, stuff about gears… It’s after a few days of these research parties, broken up by training and other things that Rias won’t stand for not doing with the whole Peerage, that Koneko admits that it is likely that at least some of the problem is possibly that as preventing her libido from getting more intense is… useful, it does make the research a lot slower.

Point proven by the surge of pleasure that comes from her knot locking her in place inside Rias as both of them go through an orgasm as she was trying, trying being a bit of an exaggeration as it goes on, to skim through the latest book that was reportedly about various Youkai. It may have some information about Nekomata, but Koneko would admit that she had only made it a few pages in after she’d entered Rias twenty minutes ago. Perhaps she should stop trying to do both at exactly the same time… It would certainly be faster.

Just because it would certainly be faster however, doesn’t mean much in the moment. With a snarl Koneko pushes the book aside and continues slamming her hips into Rias’ soaked cunt, stirring up the deposits she’d already made there again and again. “Mmm, such a good bitch… always so willing to take your Master’s knot…”

“My Master’s doggydick feels so good inside me, how could I ever refuse it?” Rias groans out, her hands cupping Koneko’s own bust, the improved size also causing Rias to enjoy playing with them when she can reach them especially during sex.

Koneko loves it, the crimson haired princess is deviously pleasurable in her quest to ensure the catgirl with a canine cock is as well pleasured as possible. If it was possible, though she suspects it would require something of a change in devil society before that, Koneko suspects she’d allow Koneko to remain at the manor constantly plowing or being sucked to continue the seemingly fruitless quest of emptying Koneko’s large balls.

Koneko’s ears flick toward the door of the library, though between how good Rias feels and her libido demanding she continue, she doesn't react in time to pull out and cover, if she even would have… the decision doesn’t get time to make any such decision, before they enter. ‘They’ being one of the Gremory family servants, who made it several steps into the library and into visibility, pulling a cleaning cart and humming happily, before she stops and turns, yelping as she starts to cover her face.

Rias moans before she shakes her head, managing to just get out, “What have I said about my dressing habits Mirabelle?”

“To… ignore it. I… Yes Miss.” Mirabelle replies reluctantly, no doubt remembering every time Rias or the head staff informed a newer member of the manor’s staff that yes the Heiress was next to naked, or occasionally actually naked, but that they should pay it no mind. Koneko knows it’s an easier task to say than do for most of them, though most of them get the hang of it eventually…

For her part in all this, Koneko slowly resumes thrusting once the thing , having been in the midst of attempting to make a decision based on whether or not she’s going to actually stop, but if her bitch doesn’t feel the need to cover up or separate… she’s not going to demand it. Her libido just wants her to continue, so absent a reason to stop she doesn’t particularly feel the desire to. Having an audience who can’t seem to look away from her currently being fucked mistress doesn’t change much.

The maid can’t seem to stop looking over, very much not able to ‘act as though it’s nothing’ as she’d been informed. She’s still doing her job, but at almost every possible moment when she doesn't have to actually look at what she’s doing without risking damage she’s looking over. 

After Koneko has already been thrusting back into her for a while, enjoying the tight velvety grasp of the busty devil laying on the table, Rias seems to realize the maid is seemingly unable to stop looking over in time, though she doesn’t… stop it. She doesn’t command the maid to be about her duties, though the moment she realizes it she reddens embarrassed. Koneko’s king is visibly torn between speaking out, asking the maid once more to pretend nothing is happening, and letting her watch.

Koneko finds she kinda likes being watched, and begins to fuck her bitch even harder, deeper, the tip of her cock tapping ever so gently against Rias’ cervix every time the catgirl hilts, one hand resting on Rias’ groin her thumb rubbing against her King’s clit. She gets lost in the pleasure of watching Rias reacting as she does it and the intensity of the maid being unable to stop watching, driving the crimson haired heiress wild until her knot forms, drawing an aroused gasp from their watcher, and she starts to press it into Rias’ tight soaked cunt. Rias may be being reshaped to more easily accommodate Koneko’s endowment without losing any pleasure on either side, but every time she knots her bitch it’s something of an event and this time is no different. Rias’ back arches hard, lifting most of her spine off the table she lays on as a loud groan mixing pleasure and pain echoes through the library as Koneko pushes herself forward. Then with a pop she’s in and only a few movements later her orgasm is hitting and so is Rias’ heaviest of this session.

Maribelle keeps watching for a moment, before she finally seems to realize she’s been wiping the same table for the past twenty minutes and rushes off to catch up on her duties while Koneko and Rias recover a bit to go back to their attempts of research while keeping Koneko’s balls drained.

The next several days are indeed several days of the same, Rias either sucking Koneko’s cock like the cumslut she’s slowly becoming or being plowed like a badly paid whore, later Koneko’s orgasm has just ended when a clock ringing in a different part of the manor reaches both Rias and Koneko’s ears as Koneko’s knot is only just starting to recede. The crimson haired girl groans, but not the groan of pleasure Koneko has so enjoyed for most of the day so far, “I have to go…”

“What do you meanya?” Koneko cocks her head. She still isn’t entirely sure why the cat sounds leaked into her speech, though she did have the suspicion earlier in the day that it may be related to her abandonment of the emotional control the night before. Emotional control she couldn’t seem to quite restore all day. Maybe… maybe that wouldn’t be so bad though?

Koneko’s drawn from her internal thoughts by Rias responding with a wiggle of her hips and a sigh, “An old ally of the family is holding a ball, I need to be there as the heiress.” She groans again, “Will you be okay by yourself for the day until I get back?”

Koneko thinks it over, she knows the feeling of needing to keep going, keeping attempting to breed, is currently very distant, but she also knows how intense it had been when she'd woken up this morning, after having spent several hours the previous knight emptying her balls into and onto Rias. She’d woken up and promptly woken up Rias with a rapid hilting in her welcoming cunt out of raw need. “I could… but I would likely not be able to wait until you got home to relieve myself again nya…”

Rias groans as the knot pops free, reaching down to scoop some of the leakage onto her fingers and lick it off as she stands, straightening her skirt down over her round backside. “Mmm… that would be unfortunate… better to keep your tasty cum from making a mess in here… hm…”

“I could come with you? Might make the party more endurable for you.” Even saying it, Koneko knows it’s a terrible idea. The odds she’d be able to hold it together long enough to get out of there are not high, one might even call them utterly miniscule, and if they got caught… it could be extremely unfortunate for her King.

Rias laughs, smiling warmly at the catgirl as she shakes her head, “I couldn’t afford to disappear for twenty minutes and make a mess of someone else’ house. No…” She trails off, thinking it over as the door opens. Koneko doesn't bother covering up, her eleven inch red doggy dick hanging out in front of her as she turns slightly to find Akeno walking in.

Akeno doesn’t seem to realize that Koneko’s skirt is on the chair behind her at first, though her nose seems to be twitching the devil doesn’t actually seem to realize what it is as she walks in, posture dignified and tone concerned, “Your maids are waiting for you Rias. What were you doing in here?”

“I’m helping Koneko learn some about her people, especially given some changes that we believe are related to the contract a few days ago.” Rias replies, walking over to her best friend and Queen piece only slightly bow legged. Given the amount of playtime Koneko and Rias had been getting up to, the catgirl is slightly impressed at her toughness in not moving more noticeably.

“What about… it…” Akeno pauses as her nose finally gets her attention and her gaze realizes that Koneko’s not wearing a skirt at the moment, particularly the small fist sized testicles hanging under the long red tapered cock hanging from her groin. “Actually no, I am repeating my earlier question. What have you been doing in here?”

Rias laughs slightly, walking closer to her Queen piece and putting her hand on her back, “I had thought you might have a reaction like this… Go ahead, you can guess, what have we been doing?”

Koneko has long known that Akeno’s usually ladylike demeanor was strong, further reinforced by Akeno’s automatic first response to the very… undeniable nature of what Koneko had likely been doing with or to, depending on your perspective she supposed, Rias. Her reaction to the complete lack of care hiding what’s been going on between Koneko and the Ruin Princess drives it home however, “But… Your betrothed?”

“Yes… I will have to talk to Mother about that at some point… possibly later today, maybe tomorrow. I surely have no intention of marrying Riser. I intend only one… extremely pleasant cock.” She sighs and shakes her head, frowning, “Still, I must attend to my duties as Heiress… so I must go to the party that Mother no doubt asked you to ensure I was getting ready for.” She rolls her eyes goodnaturedly, “Why don't you assist Koneko while I’m gone? Help her figure out what’s happened… I promise… you’ll enjoy it.”

“Yea Akeno! Let’s have fun, and you can help me figure out how this happened!” The catgirl bubbly exclaims with a smile,  drawing a surprised look from the stronger Devil.

“What happened, you’re usually so…”

“Subdued? Controlled? Emotionless?” Koneko knows how she must’ve seemed to others before the night with Rias made her no longer see a point in it, besides Akeno is probably just asking because of concern. The last few days she’s barely seen her with all the fun here in the library. Except for training, where she was as focused as ever. As a result, the catgirl just shrugs, “Being with Rias made me so happy… I just didn’t see the point in hiding it anymore. I don’t want to anymore either nya!”

Akeno seems to melt, warm and happy for the other girl, she moves forward to give the whitehaired catgirl a big hug, “I’m happy for you… and you’ve gotten so gorgeous! How didn’t I notice earlier? Your titties are almost as big as Rias’!”

Koneko flushes lightly and hugs her back, feeling her nearly perpetually ready cock sliding between Akeno’s smooth thighs. As the hug breaks Akeno bites her bottom lip and slowly drops herself to her knees as dignified as she can. Koneko almost lets her reach forward and start pleasing the catgirl’s nearly footlong canine cock, but she had literally just had the thought that it is probably a better plan to at least try to only do it when the urges are getting intense enough to require it, she has some self control… she hopes. She can’t really stop herself from the nyas to some extent, but by He Above she is not going to be completely beholden to her lust, she’s more than just a walking breeding machine!

To that end, if only for her own sake, she reaches down and stops Akeno, “Not yet. Later. I need to find out what’s happening and it’s hard to focus.” She gives a firm, if happy, nod. “It’s important to know what changed me nya!”

“If you wish…” Her tone is ladylike, her words are ladylike, but the reluctance in her voice however, is not quite ladylike.

“It’ll be better for waiting,” Rias promises as she turns to the doors Akeno had come through, “You’ll enjoy every second.”

“If you insist…” She responds, slightly disappointed sounding, but still composed and dignified despite the context and loyally obeys the implication from her King to help Koneko do her research.

Unsurprisingly really, this is much better for the pair of devils, in terms of reading speed and focus. Not just because two of them are reading either, Koneko had kept getting distracted by either Rias’ throat or bouncing titties before, this is much more focusing. They do find one piece of information before Koneko’s libido once more rears its lewd head. Akeno perks up as they’d been going through it, “Here we are, this is probably important. ‘Though you may be tempted to allow your nekomata to breed with a wolfish creature I must inform you that this simply will not work. Such breeding attempts seem to be doomed to failure, as not one of the sixty attempts I have seen to have taken root, which stands out starkly with the nearly one hundred percent impregnation rate when humans are utilized.” The ladylike devil pauses, shaking her head, “Whoever wrote this was definitely old of the old satan faction… haven’t heard anyone talk like this in a while.” There’s the faint thought somewhere in the back of Koneko’s brain of it being… familiar, but that thought is as uncatchable as smoke and she gives it up as a bad job while Akeno continues reading from the book, “This is not to say that there is no utility in such things. Though they cannot impregnate their broodmare, Nekomata can be driven into their first couple heats before their bodies are biologically capable of carrying the kittens to term. Such early heats can be difficult to deal with, thus providing utility to instead pairing them up with one of the aforementioned canines. I caution against using canids with infectious natures. I have heard of only a few, but if the infection takes, it can induce mutations of an unpredictable nature.”

“Well… I guess that’s… explanatory nya…” Koneko admits, while looking at the outside of the book to discover that the book is, slightly insultingly, a very old even by devil standards, tome about ‘Animal Husbandry’. It doesn’t surprise her, even today there are some devils particularly from the Old Satan faction who would proudly say that as a Nekomata she’s of little use other than being cute or a good fucktoy, but it does make her roll her eyes that of course that’s where they found the useful information. Everything else has, at best, mentioned Nekomata or Nekoshou’s gifts with Senjutsu and Youjutsu as reasons to be cautious if faced with a trained one, but given that it had been from a manual for fighting them, it also didn’t have information on how to cultivate said gifts, as devils lack the aptitude.

“Explanatory? What exactly happened while you were on that mission?” The purple haired ‘Lightning Princess’ asks with a pointed tone. Koneko suspects she already can guess, but wants to hear it for herself.

“I went into heat, I couldn’t focus on leaving and evidently the smell of my body going into heat caused them to react despite the species divide.” The catgirl flushes in memory of the mission, the memories were best defined as hazy but what little of them was remembered was pleasure through and through. “I guess eventually my awareness returned sufficiently that I could teleport home because I must have. Three days later… I woke up with this.” Koneko strokes her still uncovered cock, it having unsheathed itself from where it hides inside her groin as her libido got more and more insistent that it would not be ignored. Additionally the still hazy memory of the majority of those few days before she’d recovered enough to leave is more than enough to cause her body to enter a state of arousal.

“That is…” Akeno trails off, biting her lower lip, “And… how did that… what was it like?” Her voice is no longer ladylike. No longer controlled, it’s almost desperate sounding. Almost.

“They fucked me again and again! I don’t really remember much though… I remember the first bit where I felt so full, and how good it felt. It was fantastic! You know, I could show you nya…” Koneko replies, her libido now leading the way as she stands again, her large red tapered cock hanging out and causing Akeno’s gaze to fall to the bitchbreaker that she had, if they were both being honest about what had happened with Rias, been offered up to appease. Akeno doesn’t seem particularly upset about that idea now though, biting her lower lip as she once more reaches out, this time without Koneko stopping her.

She lets Akeno slowly reach out and stroke her long red cock. Back, forth, the amethyst haired and even bustier than Rias devil strokes in an almost ladylike fashion if it wasn’t for how obviously interested she is… and then it quickly loses that ladylike daintiness, becoming more of a hungry stroke as both her and Koneko turn away from the table and Akeno drops to her knees, a hunger growing on her face.

The Ladylikeness of the stroking is fully abandoned not long after, becoming more slutty, hungry, and needy, with Akeno’s expression following suit. It’s enough that even without the previous arousal and libido buildup that she’d need to empty, Akeno’s giving her cock the same kind of hungry cumslut look that Rias developed, but without the number of hungry blowjobs sending her to deeper and deeper levels of desire for her next fix.

“Why don’t you suck it nya? Rias says it’s delicious.” Koneko happily chips in, reaching forward to run her fingers through Akeno’s amethyst hair, “Taking your top off might be a good idea though, Rias always ends up so messy, it’s really hot but the poor maids!” That it will give her a more direct visual of the bustiest member of the peerage’s nearly F-cup perky tits is of course completely ancillary to that.

Akeno has no problems with the reasoning, or is fully aware of the secondary reasoning and simply doesn’t mind, and her off hand starts unbuttoning the top so it can be removed as her right continues its hungry and almost hypnotized stroke. Then her mouth opens, just as the removal of her shirt is going to require even a moment of hands free, and takes the tapered tip into her mouth, drawing a happy noise from Koneko as the Queen piece of Rias’ peerage begins to bob her head up and down only moments before her brassiere falls into her lap and is quickly set aside giving the catgirl being sucked a truly awe inspiring view of her significant and gravity defying F-cup tits.

The horny catgirl can’t see a reason not to reach out and grab hold of them, nor does she want to, so she does just that, cupping Akeno’s right breast and squeezing it firmly but not harshly, enjoying the way the perky soft flesh forms around her hand, and the moans that vibrate through her cock from Akeno. The former fallen-angel’s expression gets even more sexual, and her head starts properly bobbing, going deeper and deeper, her tongue going wild lashing across the underside of the tapered dog-cock. It’s an act that draws happily pleasured groans from Koneko and more than a few from Akeno as well given the timing of the groans.

Deeper and deeper the former nephilim bobs her head, the tip starting to poke at the back of Akeno’s throat then… a loud glurk as she gags on the first attempt to take it past the opening to her throat. The second attempt does not go any better, drawing an even louder gag from the throat of Rias’ Queen piece. As much as the gags from Akeno’s throat certainly feel interesting, Akeno is hurting herself with every attempt. Rias had made it clear that it was really making her throat sore trying it that way. “This is fi-oooooohhhh fuck.” As the white haired catgirl starts to suggest that she doesn’t have to or if she does really want to, that they should probably change the angle, when Akeno tries again, and keeps pushing. She’s gagging all the way through the attempt, loud gagging filling the library, drawing a curious librarian around the corner who redfaces and leaves.

In the end, it may be the most brutalizing way, at least in relation to Akeno’s tight and spasming throat, to first swallow a cock too big for one’s mouth, and Akeno will certainly be feeling it later, but she pushes forward and somehow manages to push Koneko past her gag reflex. Her body is still trying to gag around Koneko’s cock, but all it seems to do to Akeno, persistently drawing more and more into her mouth and throat, is drive her on. She’s reacting, certainly, but mostly the ongoing gags just wildly cause flexing of her throat around the obstruction, in this case an eleven inch long tapered canine cock, which is something that is causing Koneko’s orgasm to get closer and closer rapidly. Then the amethyst haired hits bottom, her nose pressed against Koneko’s pelvis and her chin cradled by the two small fist-sized testicles hanging under it.

Koneko’s fingers find their ways into Akeno’s hair, and she starts thrusting her own, actively taking Akeno’s throat instead of relying on the amethyst haired devil to do it for her. “You feel so good Akeno, I can’t help it… I’m so close.”

Akeno doesn’t try to pull back, only looking up at the catgirl’s golden eyes as the thrusts into her throat gain steam, and her throat slowly has the gag beaten out of it, happily and hungrily allowing Koneko to ream her throat out. This pushes Koneko over the edge and after only a few thrusts she hilts herself deep into Akeno’s throat and the first rope rockets out against the back of Akeno’s throat and then down into her stomach directly. The second shot too, but as the second is finishing Koneko starts to pull back, causing the third to fill Akeno’s mouth overful, sending some leaking out of her lips onto her bountiful chest before the fourth, fifth, and sixth coat her face and chest in a sea of white. Her production, even in the last few days, has seemingly skyrocketed. No orgasm seems any weaker than the others before it, and every single one is set to fill a womb to bursting, or ready to coat every visible inch of her bitch’s hot bodies.

Akeno sits and lets the white cum wash over her until a few heartbeats after the last one has hit her and she opens her mouth to first lick her lips and swallow before she takes a big exhale and then starts breathing again and smiles, her voice hoarse as she starts to speak, “That’s… delicious.” She scops up another bit off her chest with her fingers, drawing it into her mouth with a sinfully delicious moan, “Mm… thick… smooth… and just a little salt to it… delicious. Rias enjoyed doing that too, didn’t she.”

“Not like that, but yep!” Koneko replies with a smile, not that the former nephilim could see that with her eyes still covered. “She didn’t want to try to force me down her throat like that, she laid on the bed and put her head over the edge, it took time, but she enjoyed it.”

“I’m sure she did, and yea, that was probably not the easiest way to do that.” Akeno says, cleaning her face off by pushing the white cum into her mouth, getting another groan, “But I just… I felt so thirsty… I just wanted to feel it… I wanted it all the way down. It hurt so good…”

“You enjoyed the pain?”

“Of course! It made me feel on fire in the best way! My pussy is so soaked right now…” Her face now cleared Akeno’s gaze was locked solidly on the pillar of red canine cock that protruded from Koneko’s groin, and her voice was rapidly descending to the positively husky tone Rias would have when she was in serious need of pleasure despite the hoarse quality from the previous damage from the throat fucking that was still healing, “Are you gonna put me in my place Koneko? Make me a good little breeding bitch? Break me into an unending hunger for your big doggy dick and make me your little fuckpet?” Every question is even more hungry, whorish, and depraved but it hits Koneko’s ears and seems to shoot straight to her cock.

She suspects that was rather the point but damned if it didn’t work, pushing the books aside she pulls Akeno to her feet, then bends the amethyst haired devil over the table. “Mm… spicy, but can you deliver? Don’t disappoint me~”

A growl builds in Koneko’s chest at the challenge. Her higher thought temporarily leaves the building, this new Bitch is challenging her? It draws that growl from her chest, a primal bestial sound for a split second as she rips Akeno’s skirt off, throwing it negligently off to the side, and taking the panties, a pair of hip tied skimpy ribbon panties with the groin almost entirely soaked through. “As ladylike as you are, to wear such slutty panties… You wanted something like this.” Koneko pauses, roughly grabbing them and tugging them to the side exposing the dripping wet cunt that Akeno had not been lying about, “Who am I to deny you something you clearly yearn for so much.”

She lines up and slams it home, slamming her full length and girth into the depths of Akeno’s furnace hot cunt. It both feels absolutely just as good as Rias does, but it feels so uniquely different at the same time. Rias had felt… molten, delightfully unique in how it had almost felt… fiery around her, but Akeno is pleasantly tingly, almost electrifying. Some tiny part of Koneko feels like that may be interesting, but it doesn’t manage to take control enough to actually make the thought enter her thought processes proper. Instead the thought vanishes into the recesses of her mind as quickly as it flickers through it, her slightly more mature than they used to be hips slamming into Akeno’s voluptuous form, her even bigger backside rippling in delightful waves as Koneko uses all of her force to slamfuck her as hard as she can manage. “You wanna be a breeding bitch? You want to be a fuckpet? Your holes are delicious enough, your hips… they’ll grow my kittens well… but most importantly, you’re so tight and feel so good, how could I ever stop fucking you?”

Akeno moans happily whorishly, bouncing her hips backward as her still cum covered tits slide across the table, “Don’t… just don’t. Never stop fucking me when you’re horny, tie me up, whip me, whatever you want that makes you happy. Just use me!”

Koneko blinks, surprised at the response. It hadn’t exactly surprised her that Akeno had a serious desire to be fucked after her not-vaguely-subtle dares, but the demands for her to tie her up, whip her, that kind off thing is not something she would’ve expected from the Queen piece of Rias’ peerage. Not that she was upset by the idea. Far from it, to have Rias and Akeno tied up, pressing against each other as she goes between them knotting both? It is a particularly tempting idea, but not one they can do right at the moment, it will have to wait. Not least of these reasons being that Rias is currently off at that party with Kiba, who will keep his hands to himself if he knows what’s good for him.

No, no the bigger reason was absolutely that at the present time she already had Akeno bent over and was proving her status as Akeno’s mistress, alpha, and claiming the other devil as her breeder and bitch. Getting materials to tie her up alone would ruin the moment and the primal part that had been awoken by Akeno’s challenges just wasn't having it. She wanted to feel her bitch knotted under her, quivering with pleasure as her womb is coated in inseminating cum. With that being said, there’s really little option in her mind but to go as hard as she can, trying to change up angles, feeling the tip of the tapered cock rub against a slightly rougher patch inside that draws a sudden surging groan of pleasure that repeats on subsequent hits. What that is called, she does not know, but she doesn’t really care.

What she knows is that every time she hits it, Akeno tightens up, and the fourth time Akeno starts cumming around her, not even trying a little bit to muffle herself as her screams of pleasure rip through the walls, undoubtedly getting many a red face from the staff close enough to hear it and knowing enough to understand it. The idea of this doesn’t stop Akeno and it certainly doesn’t stop Koneko from continuing to provoke the cries from Akeno, driving forward ever onward, pushing herself and her orgasm as hard as she can, she wants to ruin Akeno for anyone who might attempt to come after, to have the amethyst haired former fallen turn them down because she knows deep at heart that they would only dissatisfy after Koneko.

To that end she does everything she can, everything she worked out with three days and change of practice with Rias to utterly drive the amethyst haired devil wild, angling to brush the slightly rough spot more often, rubbing her clit with her left hand and spanking the other devil with her right, it works, at least as far as driving Akeno wild, she ripples through several orgasms in quick succession and then Koneko’s knot starts to grow, she actually shallows her thrusts for a few moments, letting her knot grow entirely outside of Akeno. Then, as it finishes inflating she pulls her hips back with an anticipatory grin, until the tapered tip of the eleven inch long canine cock is just inside the snug passage she’s been fucking so hard. Then she slams her hips back forward, slamming her knot straight past the lips of Akeno’s tight wet cunt all at once, and drawing the hardest orgasm she’s managed to draw out of Akeno so far, a crashing series of waves of crushing tightness around her as her own orgasm kicks in, causing her to be milked as hard as she’s yet been by any of these matings.

As the knotting happens she leans forward and as she grabs hold of Akeno’s beautiful breasts, squeezing them fiercely as she bites down on Akeno’s shoulder. Lifting up she licks the spot with a smile, “You’re mine now. All mine.”

Akeno seems a bit insensate and doesn’t reply as Koneko luxuriates in the sensation of her continued orgasm flooding Akeno’s womb for several more heartbeats. Then she sits there breathing deeply as she recovers, stroking Akeno’s back and hips, occasionally kissing the base of the neck of the amethyst haired devil as she waits for Akeno to recover. Akeno recovers after a few minutes, groaning as she props herself up with her arms again, shaking her head slowly, “I am going to have words with Rias when she gets back… She kept this from me and didn’t even say anything!”

“You’re not mad at me?” Not that Koneko thinks Akeno is actually upset at Rias, just annoyed, after everything the two have been through together than Koneko has been witness to, but that the former fallen hadn’t even mentioned Koneko to include her in her ire is noteworthy.

Akeno laughs, shaking her long amethyst hair and seemingly ignorant of where it trails across her cummy torso, “Of course not, that was fantastic. Spank me harder in the future, was a bit light, but that trick with that bulge… that was glorious.” She tugs lightly on Koneko’s knot, groaning heavily, “It’s still there?”

“That’s my knot. You aren’t getting off my cock till it recedes on its own…” The white haired catgirl grins, her ears flicking, “It’s great for cuddling and what I think is called aftercare?”

“It is… and this is nice…” Akeno admits as she straightens, pressing her back into Koneko’s C-cup breast, “I feel quite warm, especially here.” She grabs Koneko’s hand and guides it to above her groin.

The pair of them sit like that on Koneko’s chair until the knot eventually recedes enough, roughly thirty minutes later, that the extra cum trapped in her womb or the back of her cunt can flow out over Koneko’s large testicles. It’s the work of a moment for Akeno to move as quickly as she’s capable, kneeling on the ground again to clean Koneko up with her tongue, groaning happily as she does so. It doesn’t cause a repeat, but it is more than simply pleasant, it feels gratifying and right in an odd way.

Once Koneko is clean Akeno stands up and moves back to her own chair, in the process undeniably giving the maids a very telling mess to clean up later, and grabs a new book as if nothing had happened, ignoring the telltale cumtrails from her breasts on the table as she begins to leaf through it. “Was there anything else we wanted to go over?”

Koneko slowly shakes her head “I don’t… oh!” She perks up, suddenly remembering something odd that her and Rias had noticed over the past couple days but that had somehow slipped her mind, “I bit Rias, and you, while I was mid rut and Rias still has the mark on her shoulder, she’s been covering it up with makeup but it hasn’t healed and faded.”

“I feel like I saw something about that before… It wasn’t a Nekomata or Nekoshou fact so I discarded it because they weren’t mentioned as types of demons or youkai that often have the instinct but…” She sets the book aside, out of the cumtrails, and goes back to a few books the pair of you had gone through before and hands Koneko a few. “It’s somewhere in one of these, I just know it. Something about mating bites…”

The both of them go through the suggested books and indeed as Akeno had attested there it is, deep in a book about ‘Youkai with Animalistic Traits and their Habits’ by the Governor General of the Grigori Azazel, the reference they’re looking for. Koneko perks up when she finds it, “Here it is!” She pauses and clears her throat, “In specific circumstances bestial youkai have been known to bite the female underneath them when they seem to believe the bitch to be weaker or subordinate to them. This bite will last until the youkai who laid it is dead or has given up their claim on the female. If the female is stronger than the youkai who laid the mating bite,” She pauses and looks at Akeno, “Which I’m not… oblivious enough to pretend neither you nor Rias are.” Then back to the book, “Then it seems to follow the concept of subconscious consent and submission to the youkai despite their greater strength. As of writing this book, I have only discovered this occurrence once in my years of research.”

“It requires subconscious consent huh… I wonder if that could be enough to get rid of her betrothal without any issues with the agreement…”

The catgirl pauses, cocking her head, “Maybe but… Ah, no.” Koneko shakes her head with a frown as she reads a bit more, “Though many Youkai will be able to detect and acknowledge, even often respecting the mating bite without issue, Devil and Demonkind have no such ability to detect the bond, and the few attempts made by youkai turned devil to have it acknowledged as a legally binding bond have been met with derision by the satans.” She closes the book and puts it aside, “Sirzechs is her brother, and the others are neutral at worst, but it could cause problems to have that be decided officially by the satans so soon before it’s revealed that Rias has received a mating bite from a Youkai. Maybe later after it’s already dismissed it might be a good idea…”

“Ugh, politics… They almost make me wish I’d moved in with dad after I got kicked out of home before Rias found me… only almost mind you. The politics aren’t that annoying,” She smiles as she leans back relaxed. “Besides, maybe I’m a bit too relaxed after all that right now, but I’m not feeling too able to feel too upset about politics when it leads to fun like that.”

“I’ll have to though…” Koneko groans, throwing her head back, “I just want to fuck my bitches and have fun, why do I have to worry about all this stuff.”

“Your bitches hm? Well… I can’t say I’m upset about that… it was fairly pleasant… but maybe I need another test hm?” She asks with a seductive lilt in her tone, standing again and turning sultrily to grind her round backside up against Koneko’s groin, drawing her cock back into the open as it rapidly awakens to the situation. “Break me big girl… I can take it. Make me feel it tomorrow.”

True to Akeno’s request, Koneko does just that. Spanking the former fallen angel harder than before, thrashing her backside until it’s red and every new spank sets off another micro orgasm. With all the squeezing and attempted milking from Akeno, it’s not long before the amethyst haired devil is knotted like a good bitch and insensate on the table when Koneko hears the door open.

“I told you you’d enjoy the wait,” Rias’ voice calls out from the opened door, Koneko turns her head to find her first bitch walking over with a seductive gait. “Didn’t disappoint, did she Akeno?”

“Ah… She’s a bit out of it at the moment.” Koneko chips in after a moment of no response from Akeno whose orgasmic aftershocks were still rippling around Koneko’s knot, milking her as much as possible. “It’s nice to see you again though.”

“It’s nice to see you too my love.” Rias replies sweetly, leaning in to kiss Koneko, groping her far asscheek lightly as she caresses her, “How about you then? Have you enjoyed my oldest friend? I see you found out about her affection for physical discipline.”

“She begged me for it during the first go actually. I wouldn’t have thought she wanted that, she always seemed more like she would go the other way.”

“Not Akeno.” Rias replies affectionately, her hand now caressing the amethyst haired devil’s back, “More Bark than bite that way I’m gratified to say. There’s something else though… Would you mind lifting her up?”

Koneko quirks her eyebrow slightly and Rias shakes her head, repeating the question silently with a wave of her hand. Shrugging Koneko leans forward and gently puts her hands under Akeno’s shoulder at the front through her armpits and lifts, drawing the taller girl vertical as Rias leans forward. Akeno shivers a bit and Koneko can barely make out the sound of a tongue caressing something before Rias cleans her lips and she leans back up, “I was a bit nervous that might be the case…”

“What is it? Do I taste weird?” Akeno had just said that she tasted delicious before they’d started, but Rias’ reaction still sparks a concerned look from the catgirl.

“No… no you still taste delicious my love, no it’s what I was licking the cum away to see if it was present. Look at the skin above her womb.”

Koneko leans around as best she can while still being rooted in Akeno’s cunt and manages to spot something pink and glowing roughly where Akeno had put her hands earlier as they were cuddling after the first round. Curious she un-contorts herself and looks to Rias to find her King has removed her dress with magic, showing another glowing symbol on Rias’ body in the same place. “This appeared at some time today, maybe while I was at the party. I… do not know what it means, but I am fairly positive of one thing… I think we may have to talk to Mother about this.”
