Happy late Halloween, everybody. In case anyone's wondering, work is going smoothly with some completions on the way this week.

Halloween Singularity 2022- A Hallowed night of Sucubbus Merriment

*****

Somewhere inside a place of unknown time and origin, Ritsuka Fujimaru awoke with a groggy fuzz and a slight ache in the back of his head. The dark-haired, teal-eyed boy looked up from the ground somewhere inside an odd-looking village sometime at night. There he saw many things pertaining to modern-day Halloween decorations such as Pumpkins with goofy faces carved into the surface, many upon many flowers and reeds with things like candy bats or skulls sticking out of them rather than proper flowers, and lastly, the houses of the settlement he was in having somewhat cartoony designs. There were many other odd-looking aesthetics sticking out noticeably to the laster Master of Chaldea that he found quite odd for any kind of location in Proper Human History, but as he tried to move so he could look up at the night sky, he found that he was actually bond like by the ankles and wrists like some kind of hog.

It was here that he became fully awake and alarmed while nervously sweating to himself, thinking he had already been captured by whoever was causing the Singularity he was in. He did remember the Da Vinci women and Sion Eltnam telling him this was yet another Halloween Singularity that just popped up out of nowhere for the Master/Breeding Boy of Earth. But he didn't expect to wake up like this, wondering just what happened to everyone else.

"Gughh...! I'm...bound?! W-who's doing this? And where is everybody else...?!" Ritsuka asked himself in slight awareness, hearing a seductive feminine voice from close by as he wriggled helplessly about on the brick ground in glowing violet bindings. He was still wearing Mystic Code clothing consisting of a snappy dark dress shirt fitted for combat with a pair of dark grey pants and form-fitting boots designed for mobility and warfare. 'How could I have woken up today with the latest Servants I had to knock up in my arms, only to wind up in this situation after agreeing to solve a surprise Singularity?!'

"Fufufufu, ohhhh...looks like you're awake now. Splendid.~" The voice called out to him, making the boy hear the collection of soft footsteps and clicking heels coming in his direction. Ritsuka perked an eyebrow when he recognized that voice and figured it couldn't be who he thought it was unless....it was another version of her that came with the Singularity. That kind of thing wasn't uncommon considering alternative versions of Servants appear all the time, but still, he was concerned since this particular woman was a special case for him.

Hearing the clicking of footsteps grow louder until a shadow loomed over his form, causing Ritsuka to look up and saw who it was that had apparently bound him when arrived in this place. His mouth fell open in surprise and shock while a certain part of his anatomy lurched hard from inside his pants.

He saw Irisviel Einzbern herself, but not the Heaven Dress-wearing Caster Servant he made love to back home, but rather a version of her wearing an extremely sexy Succubus outfit leaving nothing to the imagination as she stood above him in a sexy pose. The pale-skinned beauty of Grail War history stood there with her hands on her hips, curved Succubus horns sticking out of the sides of her head while bat-like wings stuck out the lower half of her back as she showed off an extremely skimpy design. Over her immaculate, womanly body there was the skimpy outfit consisting of dark violet strips lined with gold barely covering up her ample set of D-cup-sized breasts and nearly showing her pubis while wearing matching sleeves over her arms. Over her long legs, she had matching leggings with high heels at the bottom and a devil's tail sticking out of the lowest part of her back. Her hair was as long as always in all its shimmering, silver glory and in the same style as his version of Irisviel had, apparently being some kind of alternate version of her.

Honestly, the sexiness of her ultra-skimpy outfit made Ritsuka begin getting hard as he eyed her questionably with a nervous smile.

"And you are...Irisviel-chan by chance?" He guessed and saw her no with a giddy look on her face before flapping her bat-like wings a bit and brandishing her tail with a sexy smirk on her lips.

"Kinda, but not exactly. I'm a Succubus version of Irisviel Einzbern and I...am the one who became the greatest Succubus in all of Halloween land by using the power of the Holy Grail. I take it this is what you're here to get, right?~" She said, making the coveted artifact of Unholy Magic appear above her right palm, surprising Ritsuka completely as she swiveled it around before making it disappear into a pocket dimension only she has access to."Hee hee, you may think of me as the Halloween Princess around here and it is so very nice to finally meet you, Ritsuka Fujimaru-Kun. Fufufu. We're going to be spending lots of time together....starting now.~"

Halloween Princess Iris said with a seductive giggle as she raised his body from the ground with a flick of her fingers.

Being a Succubus as well as whatever kind of entity she was in this Singularity, gave her some degree of amazing power and she was using it to coax Fujimaru into giving her his body. She lowered her eyes into a bedroom stare rife with lust and ran her tongue across her lips before walking over to the mid-air suspended boy and promptly pulling his pants down with a tug of her slender fingers.

!

"Gngnhh! Hey.....! First, tell me what you've done with the others...! I n-need to know where everyone is at and if they're okay!" Ritsuka let out, blushing a bit as his thirteen-inch cock came springing out in a fully erect state before Hallowee Princesse's eyes. Her red jeweled orbs widened in surprise and her lips instantly curled into a wide, salivating smile as she admired its thickness from top to bottom while feeling extremely horny already.

"Oooohhhh! You are big! Yes...! Anyway, you separated from them already when I found you, you know. I haven't seen them and I don't care to. What matters right now is sucking the seed out of this immaculate dick and into my mouth. I'm glad it's big, and complete with large balls too. This is such great news since it means you must be full of virility and life and will be able to give me all the empowering essence I need. You should be thankful, Fujimaru-kun. Not many men get to be sucked off by a Succubus, you know. Well, any that live anyway. Fufufuu...here I go.~" Halloween Princess says with a sultry smile, dropping down to her kneecaps and spreading out her legs a bit as she grabbed onto the thighs of Ritsuka's hovering body. She brought her face closer to his cock, admiring it up close and feeling the life-giving essence exude a radiant Aura from his balls as she started running her hands along his groin before promptly swallowing the tip into her mouth.

*Schloup!*

"Mmnnhhhmmh! *schlurppp!* Mmhmmmh....*So big...too...!*" Iris moaned, looking up into Ritsuka's eyes and seeing determination staying on his face rather than a whimpering exaggeration of pleasure like she expected. It seemed he was already used to something like this considering he's fucked and bred his way across a good number of Servants already, one woman being a literal Beast Alter-Ego, and the other handfuls being Divine Servants giving flesh bodies.

Still, he couldn't help but moan loudly as he felt the ungodly tightness of the woman's slick lips squeezing gingerly around the head of his neck until she wrapped her hands around the base so she could start sliding herself down. Ritsuka prepared himself to lose it if a Succubus's ability was anything to go by. As a man, he didn't have a chance and felt the warm sliminess of Halloween Princess's throat greet just a couple more inches of his cock when she started lightly sucking him off.

'If I can survive being blown by Tiamat as well as Mash, Vitch, and Artoria, then I can certainly survive a Halloween Succubus version of Irisviel-chan, right? Nngghhh! Better hold out because she's.......not sucking as hard or as good as I thought....' He trailed off, feeling tiny amounts of pleasure as the woman's blowjob was coming off as incredibly shallow despite her head moving back and forth into his crotch.

True, her smooth hands massaging his groin and the base of his cock made Ritsuka bristle with sensation, but her technique was nothing outside of amateur level when it came to sucking him off.

*Schlupp......shclupp.......schlupp.....shcluppp...schluppp.....schlupp..pop!*

"Mmnhmm..hmpp...mmhmpp..mmpppp...! *Pop!* Ah...! Having fun yet? Fufufuu.~" Halloween Princess asked, seeing an unimpressed Ritsuka staring flatly at her from above while she nervously began sweating as though she had been found out.

"No, not really. You're......doing an amateur job right now, Irisviel-chan.~" He pointed out, cutting into the woman's pride already as she averted her eyes, blushing nervously while rubbing the back of her neck. "You know, if I had to guess I'd say you're actually a virgin aren't you? Most alternate variations of other Servants tend to first exist in a Singularity and seeing as how they are no citizens or whatever in his place, I'd say that maybe you're actually a novice who's never done it before, right?"

"Gahhh! N-no! That's not true! I am a Succubus, yes...! I've fucked and sucked off many men before....so you....show me the proper...respect?" Princess's voice grew smaller when she saw she wasn't convincing him at all. Ritsuka continued to stare flatly at her with an amused smirk on his face, knowing she'd been found out for being a virgin despite her appearance and composition as a sex-hungry creature. "Ughghh! Alright...! Not ye! I was just getting warmed up! Here!"

She grabbed a bit harder onto his dick with her hands, causing Ritsuka to wince but easily endure as she brought her mouth back onto his cock, trying to slide it a bit further while choking just a bit in lingual sputtering.

*Glruchh!*

"Mmnghhhh! Hmpp..mmppp...mhmpp...mmhmpppp....*Schlupp...schluppp..schluppp...schlurppppp!* Cum already...!" Halloween Princess let out muffled moans, languidly tasting only one-third of Ritsuka's cock and doing a very poor job at actually stimulating him after everything he's been through already. The young man had a bored look on his face the entire time, waiting for something to give as he felt the slimy insides of the Succubus's mouth continue to orally pleasure only a portion of his cock at a barely acceptable degree.

"You might want to use your tongue a bit more, or at least feel me up to see where there are certain places that might serve as my erogenous areas. I mean, c'mon, I've gotten better head from other Servants who've had no experience in their past lives. Even got my entire groin sucked by a large, monster woman Beast with a killer body. You're...just not in their league, Halloween Princess Irisviel-chan.~" He mocked, earning a glare from the woman as she continued to try and prove him wrong y sucking him off even harder with haphazard attempts at proficiency.

Lurid slurping noises come out and Irisviel the Halloween Princess, failed to get Ritsuka to cum after blowing him for nearly five more minutes before giving up. With a wet plop of saliva, she pulled her face off of his crotch and huffed irritably, seeing his member was still hard and not twitching with the need for expulsion.

"Fine! If you're so good at getting sucked then, by all means, show me how to do it the way you like. I'll release you, don't even think of trying anything funny since I can overpower you easily and bind you back up." Halloween Princess yelled, snapping her fingers and making the glowing binds of Mana disappear from around Ritsuka's wrists and ankles as he was let down onto the ground before her.

"Ah, finally...now then. Time for a crash course.~" He said, smirking evilly as he suddenly grabbed onto each of Princess's horns, using them as makeshift handlebars and forcing her onto his crotch in a rough shove where nearly all of his dick plunged down her throat before she was ready.

*Splotch!*

"Ghmmngghhhh!!! Mmngghmmhhh!" She moaned loudly in surprise, feeling the urge to gag on his monster cock as he began bucking his waist into her face in a feverish and savage manner. His groin tapped raucously against her nose, forcing Irisviel to shield her eyes from his pubic fuzz as she felt his beefy monster prod the back of her throat like so.

"Uunngghhhh! Yeahhh! Now we're talking business! Mmnghh! Your slick, tight, slimy little throat feels like a pussy when you're really giving it your all. Unnghh!~" Ritsuka let out, making Princess's mouth gulch and slobber all over his cock as he repeatedly plunged it down her throat, grunting like a beast as he made this version of one of his lovers pleasure him forcefully by slamming his waist into her jaw.

"Ghmpgmnghhh! *Schlopp...shclopp..schlopp....shclopp...shcopp..schlopp..schlop!* Mmnghhghhhh! *It's too much...!*" She moaned languidly with her eyes beginning to roll up as she feels his dick pressing down onto her tongue while pushing it to the very back of her throat time and again. It was such an intense, savage feeling having him crudely use her gullet as a cunt, but Irsiviel was finding that she liked being treated awfully by the man she sought to drink sperm from.

Lurid slurping noises came about constantly as Irisviel Succubus's throat made for a rather sloppy blowjob with her lips constantly gushing saliva as Ritsuka plunged his dick down into her throat. She could barely keep up with his passion and honestly wanted to claw him off if it were not for her growing need to have more of his cock sliding down her throat. Her tongue slithered around his shaft, stroking it feverishly while it was busy plunging into her gullet with Ritsuka face-fucking her with a smile. For him, it felt like a tight oral pussy that was not only ultra-slick but squishy and tight to boot. Princess's mouth served as the perfect onahole for this man.

Her eyes widened with alarm when after a couple of minutes of this insanely abusive throat job she was giving him, she felt his shaft begin to throb like an organ inside the depths of her throat. Looking up, she saw that it was confirmed when Ritsuka tossed back his head and growled loudly as his bucking increased frenziedly in pace.

"Uuaaggghhhhhhhh! Fuck.....! Ughhhhh! It's time...Princess...! Nghhhhh! I'm going........cuummmmmmm! Aaghhhhh!~" He let out, practically slamming Princess's head onto his pelvis as he fucked the inside of her throat with gusto, allowing his cock to pump her mouth without mercy until he came with the pulling of her horns!

"*Mmnngngghhhhhh!?~" Princess's face was practically smothered into his groin as she felt his gargantuan meat tool pulsate and expunge heavy amounts of sperm down her throat like so. Her cheeks instantly puffed up and her eyes went wide with an absolute surprise for she could tell he was as virile as a horse! Still, it was a bit painful for her to have streams of sperm gushing out from her nostrils due to how much Ritsuka was putting out.

*Splurrt...sppllurrt...sppslurrt..spplurt..spplurrt...spslurrtt...spplurrt!*

"Ghngghhghh! Ngbgbgghhh...! S-s-so muchh....! *Gurgling noises..!* Nnghhhh!" Princess tried her best to swallow down as much as she could, relishing the flavor of potent seed while drinking it down like a wondrous smoothie made solely for her. She grabbed onto his hips to steady her face, keeping it aligned with Ritsuka's pelvis as he held her for a little while longer. Cum spilled down her throat en masse, nearly drowning the perpetually frisky Succubus variant of Irisviel as she swallowed his seed as fast as she can.

Loud swallowing noises were made clear to be heard from her throat while Ritsuka went on for nearly another couple of minutes while Iris made sure to coil her prehensile Succubus tongue around his dick to milk more from it. She swallowed and gulped as loudly as possible, struggling to not leave a trace of it outside of her lips when he was done. Ritsuka let out a blissful sigh of relief and let go of her hands, allowing her to pull back and choke several times while his cock stood out remaining fully erect. A splotch left her lips and some residual sperm trickled down the woman's chin as she clutched her throat.

"Uunghhhh! *Cough..cough......!* Oohhhhh....even for a Succubus, babe, that was a little too much....! Oohhhh..my.....! So dizzy....and so much sperm in my stomach....!~" Princess giggled somewhat deliriously as she reveled in the sight of Ritsuka having a sense of unwavering virility since he had yet to go flaccid even after cumming a liter's worth of sperm into her mouth. She was still letting out a ragged breath, trying to regain her sense of stability for a bit till she saw Ritsuka grinning evilly just before reaching down to grab ahold of her arms.

"Oohhhh no, I'm not even close to finished yet, you beautiful Succubus. Daddy Ritsuka needs a lot more than that to be fully satisfied.~" Rtisuka said, growling briskly as he pulled her to her feet and took advantage of her disorientated state to clutch her pubic mound through the scant amount of clothing, eliciting a squeak from Princess and a dark blush of sexual arousal till he tore an opening through that particular region of her clothing.

*Riiiippp!*

A loud tear of fabric came, as a result, revealing Princess's tight-looking pussy in full with a few silken hairs of platinum pubic hair directly below her navel. Her pussy folds looked as tight and as fresh as any youthful virgin could be, she was as pure as driven snow from what Ritsuka could see. Not only was this version of Irisviel Einzbern a virgin trying to pass herself off as one ultra-slut demon, but she was also extremely wet from the rough blowjob she had 'given' to him just a moment ago. He could practically see her insides throbbing with those velvet, pink virgin folds secreting so much juice from her arousal. This had Ritsuka grinning like a devil as he flashed Princess a smirk just before grabbing onto her hips with his hands.

"Wha.....! W-what are you doing now, Ritsuka-Kun....?" She nervously asked, feeling a little afraid of the Master she just tried to seduce and keep as her pet. The woman's eyes were still on his immaculate cock as it remained so thick and large that it was hard to believe he would tire out.

"What do you think? I'm.....going to fuck you like a ragdoll, Princess. You had no idea what you were getting into when you decided to 'draw essence' from me of all people. I have about several dozen Servant women back home that could tell you the whole story, but for right now......" Ritsuka promptly turned Princess around to where her plump, heart-shaped ass stood above his naked groin until he lifted her up off her feet. She didn't even try to stop him since she was still very disorientated from having nearly drowned from swallowing his cum. "..you'll just have to experience for yourself what I'm talking about.~"

"Gyaahh....!" Princess squeaked out again in surprise as she felt each of his arms sliding up over her armpits, binding her them back to where she couldn't move while feeling his immaculate cock pushing out from underneath her groin. She could feel the raw heat and sheer power of his appendage even when having it rubbing smoothly against her folds from below. It was making her body become extremely excited and filled with sexual energy, but Princess still wanted to regain control of this situation and dominate him as a proper Succubus should in her opinion.

The last time she checked, he was supposed to be her prey and not the other way around. So she tried squirming in his arms for a bit once she felt some of her strength return, but by then, Ritsuka had crunched his pelvis down and aligned his cock directly with her sex so he could push right in with a fierce thrust! The bulbous tip of his cock plunged straight through Princess's folds in a firm push of raw penetration which shocked the Succubus Servant to her core as she felt her insides splitting wide apart!

*Squelch!*

"Ghaaaaaaaahhhhhhhhhhh!~" Princess cried out in pain, feeling her insides light up with ecstasy as she was becoming impaled fully onto his cock. She could feel it pressing apart her insides and sweltering inside of her walls as though she was being taken by a literal animal like a bull. Ritsuka had fully impaled Princess onto his cock, letting only a third of it inside as he had pushed past her hymen upon rupturing it with ease. He could feel her creamy, heart-shaped buttocks now wriggling away into his waist while making sure she was pressed down all the way onto his crotch with his arms keeping her there in a Full-Nelson position.

Princess's legs were now squirming about in the air, kicking helplessly into the sky in defiance while seeing a massive bulge protruding noticeably from inside of her stomach as Ritsuka had already entered her womb by force. She'd writhe in pain and whimper in agony if it didn't feel so good inside of her right now, but she was still intending to be the dominant one in this despite feeling sensational pleasure at the mercy of his cock.

'Uueahhhh! He's that huge....!? It feels like a literal arm is going inside of me...! Oooahhhhh! N-need...to get him....off...! I'm supposed to be in control...! Have my way with him....n-not the other way around....uuaahhhh!~' She thought to herself, clenching her teeth with a dark blush coloring her face. Never had the Halloween Princess Succubus felt this kind of sensation before today.'

"Oohhh..yeahhhh! Ummnghh! You've got to have the absolute tightest pussy I've had in a while, Princess. And that's saying something considering I've had everyone from Tiamat herself to the holy Maiden Jeanne D'Arc along with many tight 'virgin' Servants that are as sexy as you. Mmnghhhh! Your insides are just so slick, snug, and slimy...! I'm going to start fucking this naughty body of yours now, Princess. Rail you just the way you'll like it..!~" Ritsuka growled into her right ear, licking his tongue up around the woman's neck before beginning to piston his waist upward in a series of slow-moving thrusts into her groin.

Loud pelting noises of flesh colliding with flesh soon erupted in a series of incessant collisions between their bodies. Princess was feeling her creamy buttocks squishing constantly against his frame with her mind becoming addled by the sensation of the massive cock now drilling her insides in a very thorough manner. In and out it came, plunging almost entirely into the squishy vortex of her right, pink folds with his balls slapping into her buttocks. Each push of that rigid slab of meat had her insides twisting gingerly around it, sending jolts of ecstasy throughout the Succubus woman's body non-stop.

"Aaahh..aahhh...aahhh...aghh..ahahh..ahahhh....g-get...off of...m-me..aahhhh!! Y-you....were supposed to..aahhhh....be underneath me...with me in control....aaahhhh!~" Princess cried laboriously in pleasure, uttering small gaps of breath repeatedly while her body undulated along the curvature of Ritsuka's waist. He kept his pelvis at a low-to-the-ground power angle with his cock pistoning upwards into her sex.

Hearing this had him grinning smugly in victory for he knew that once any Servant woman gets his cock inside of them, they would melt like ice cream in a short time. And from what he could feel, Princess's ever-tightening folds were giving him the impression that she was getting ready to cum real soon. She didn't even have the strength to try and pull herself off of him since each push sent her insides coiling around his cock in response. Ritsuka enjoyed the fact that each push he made into her untouched vaginal depths resulted in small gushes of moisture coming out of her pussy.

Princess's tongue threatened to roll out of her mouth and give her a nearly complete ahegao-style expression on her face, it was something he was used to seeing on all of the women he's fucked into pregnancy so far.

"Mmngh..mmngh..mmngh..mmngh..mmgnh..mgnhhhh! Princess! Your pussy is so tight and it feels like it's wanting me to drain every ounce of sperm inside of you and get you pregnant! *Princesses winces in comically-shocked horror* Oh you better believe that I am going to cum so much you'll be left with a bloated belly when I'm done! And I won't be done for a long time...!~" Ritsuka let out, growling briskly with euphoria as he repeatedly bucked into the Princess's frame while she was still trying to wrench herself off of him by flailing her arms behind his neck.

It was ultimately a futile effort since her body was held in complete submission and Ritsuka's cock churning feverishly through her insides left her unable to properly think about anything outside of the sensation of it plunging through the depths of her womb. The woman was shuddering blissfully in sexual relief the entire time, hating the fact she was now the complete submissive to what should've been a predatory practice from her in hopes of draining a powerful Master's essence dry.

"Aaahhhhhh..! Aahh...aahhhh...aahhhhhh...aahhhh....aahh..aaahhhh!! N-no.....! M-must....turn this...around...aahhhhhh! It's seriously pushing into my womb and making me c-closer to c-cumminggaaaaa.......aaaaaahhhhh!~" Princess cried out as she felt Ritsuka change speeds when he was now pushing everything inside of her twat all at once. His hips swung faster and pressed harder into her frame, making her womb act as little more than a condom for his cock that was now battering into her walls like a flesh-made battering ram.

The woman's bulbous tits were jostling about voraciously to every one of his movements and staying that way while she was slowly losing her mind to pleasure. Amidst all the bouncing she was doing right now, Princess caught the sight of a flash of light energy appearing somewhere in the distance just a few feet away. This also caught Ritsuka's attention as he continued bottoming out of the Succubus's tight pussy and looked over one of her shoulders to see who it is that arrived. Appearing in a flash of Divine energy and wearing a glimmering white robe he recognized as the Heaven's Dress draped seductively over her curvaceous body which donned a swollen seven-month pregnancy stomach, was a certain Irisviel variant from his Servant party that he went into this Singularity with. Ritsuka recognized her and immediately smiled in joy and relief when seeing Irisviel Einzbern, Caster Class Servant who wears the Heaven's dress and is one of his many child-bearers at Chaldea.

"Iris....! You're here and you're alright...!" He beamed, keeping the repetition of sawing out the Succubus pussy going as Irisviel Caster walked up to them with hips swaying salaciously from the inside of her scandalous dress.

"Master....! I finally found you, and I'm so relieved to see you're alright while... heheh..getting 'acquainted' with another version of me. I take it this is the source of the Singularity that you're currently 'handling' right now, yes?~" Irisviel Caster guessed with a playful and alluring tone. She was purring seductively to herself in growing arousal as she watched the primal breeding going between Ritsuka and a mirror copy of herself wearing a very slutty Succubus attire. She ran a hand down her bulbous, child-bearing belly with a smile as she approached the two of them, already seeing a future in which this Succubus version of her winds up bearing his children too.

Caster Servant Irisviel Einzbern looked exactly the same as Halloween Princess Irisviel, the sole exception being their assigned clothing which was as different as day and night. Caster Iris was wearing Heaven's Dress, which was a mystic and sacred garb used only for Rituals involving the Holy Grail War and summoning it with the person wearing it to be used as a sacrifice of sorts. That wasn't the case with Irisviel Caster as she had become a Servant when she died during the Holy Grail War timeline where she was from, leaving her in this magical Dress which was as elegant as it was sexy since it left much of her body exposed. Only her swollen breasts were adequately covered up, albeit barely since the top and bottom parts of her attire were detached with the top part draping over her tits like a curtain. The lower half remained barely hanging off of her hips, giving Ritsuka a nice view of her pelvic bone and her navel. The pope-like hat remained atop her head at all times and despite being pregnant, she was still a necessary part of the team as its resident healer who goes wherever her lover, Ritsuka, goes when investigating Singularities.

"T-that's...ahahh..ahhhh..ahhhh...the other me!?....aahhhhhhh! And....s-s-she's pregnant....?!" Halloween Princess Irisviel let out between lurches of her body and a voracious series of moans and gasps for air.

Caster Iris got in close and examined Princess's seductive and highly-skimpy attire, understanding how her Master would get so riled up to be able to 'overpower' the source of this Singualrlity already.

"Fufufu, that's right. Master here is very virile, you know. It's almost as though he was a living Sex-God in human form. You'll understand that yourself soon enough when you start looking like this. *gestures to her pregnant stomach* And believe me, it's a very worthwhile experience in which no other form of pleasure comes close. Speaking of which, I shall assist, Master. I can't let you have all the fun to yourself, and besides...you're getting two of me at the same time. I think you always wanted that. Fufufuu.~" Iris informed, running her tongue along her lips as she lifted up the loose-fitting parts of her robe up from off her stupendous G-sup-sized breasts.

Her nipples were darkened as they were clearly lactating, making Princess gape at them in shock until she saw her Priestess-looking counterpart drop right down to her knees and place herself between Ritsuka's legs.

"Heheh...! Go wild, Iris....! I'm getting to blow soon and knock up this naughty little Succubus variant of you. You can believe that we'll bring her back with us to serve as another pregnant bitch for our pleasure. So knock yourself out and enjoy my balls, treat them nicely with that incredible tongue of yours.~" Ritsuka said, tightening his hold around Princess's armpits as he began thrusting more raucously into her sex from below, resulting in louder splotches of moisture now gushing out of her folds and all over Caster Iris's face.

The White-clad Servant looked on with glee and soon parted her lips as she kept her eyes focused upwards at her clone, marveling at the sight of her Master's cock cleaving in and out of her pussy when she brought them around one of his balls.

"Hee hee hee, of course, Master. Haaamm....*Schlop!*...mmhmm!~" Caster Iris moaned warmly as she wrapped her lips around the surface of one of his bloated, clean-shaven testicles while gently grabbing onto the other one to massage within her right hand. She kept her head tilted back slightly as she began sealing an airtight aqua seal of moisture and saliva around the one she had in her mouth, sucking on it gingerly like so. "Mmhmmhm...*schluurpp..schlurppppp...schlurpp..!* Mmnhmm.hhmmm..mmnhmm...*Schlurppp..s.chlurpppp!..s.chlurpp!*....ahmm~"

Princess looked down, seeing her other self leisurely sucking on his balls in turns and gingerly fondling whichever testicle she didn't have her mouth slathering saliva all over. It was such a decadent, titillating sight that made her insides lurch even more as she continued bouncing around on the Master's pelvis while her insides started squeezing even tighter around his cock. It sawed in and out of her cunt, causing small gushes of moisture to escape her nether folds and letting Princess feel her toes curling up as she considered the possibility of becoming pregnant with his children.

"Ahhhahh..aahhh..aahhhh..aahh..aahhh..aahhh..aannhhhhh!! N-no....! I...d-don't want to get pregnant!... I c-c-can't even believe Servants could get pregnant...like that...aahhhh...other me...! Uuaahhhhh! Noooo...I'm going to cum soon...aaahahhhhhh!" Princess cried out, smiling more noticeably in ecstasy as she continued to feel Ritsuka's cock carving out her insides non-stop for the next several minutes while Caster Irisviel continued rolling her tongue all over his jiggling balls with gusto.

The holy woman Servant feverishly suckled and licked up every modicum of flesh, admiring the sight of Princess's body beginning to seize up with an impending orgasm. Soon enough, Ritsuka himself was growling loudly with euphoria as he began to feel his balls lurching with the release after the next dozen or so thrusts of his cock. He tilted his head back a bit and kept Princess firmly held within his arms, bucking his pelvis voraciously into her rim while her pussy gushed all over his cock in a mutually-achieved explosion of orgasmic release!

"Gaaaaaaaaaaaahhhhhhh!~" Halloween Princess screamed out loud in ecstasy, arching her back slightly as she felt her insides clutching onto Ritsuka's cock before he came! The lad pushed his pelvis as far into her buttocks as he could go, feeling the relief of his balls spewing forth thick ropes of sperm directly into the Succubus's insides.

"Mmngghhhhh! Get pregnant..! Aaaannhhhhh!~" He grunted with pleasure, enjoying that Caster Iris kept swirling her tongue around his cock while this went on. She watched his member swell and send bulges of cum upward, directly filling the Halloween Princess's womb like so.

*Spplurrt...spplurrt...spplurrt..sppllurt..splurrt..spllurrt..spplurrtt!*

'No! No! No, no, no,noooaaahhhhhhhhhh! I'm getting pregnant! I can feel it...! There's so much of it going inside of my womb and beyond..!' Princess thought to herself as her feet curled up with her insides lurching intensely around his cock in orgasm. The warm goo of his seed filled her womb instantly, drowning out her uterus and giving her the preconceived vision of the man's many sperm cells fluttering toward her eggs. She knew it was a fact now and continued to feel him injecting thick streams of semen directly into her pussy for several more minutes until he was done. "Ooghhhhh....there's...too much...! Hehehehhh...but oh dear me...it felt so good.....!~"

Caster Irisviel took one last suckle of his balls before removing her face from between Ritsuka's legs, watching him gently get down on one knee to lower Princess to the floor after he let her go. Her limbs had gone ragdoll and there was an abundance of sperm oozing out from between her gaping folds with a delirious smile now appearing on her face. Caster Iris could only think to herself; a new pet to bring home with them.' With a splotch of moisture and sperm, his cock came free from the insides of her sex and stood erect directly above Caster Iris's face with messiness all over it. There were entrails of sperm still caked over the upper half of the surface as well as moistness hanging off of it, courtesy of Princess cumming like crazy all over his cock even before achieving climax.

"Clean it for me, Iris, if you please. And then remove the lower half of that garb, because I'm going to want you on top of your sexy Succubus counterpart for the next round.~" Ritsuka commanded with confidence and saw the pope-themed Caster Servant gleefully obey his request before leaning over to swallow up the entire upper half of his cock with her mouth.

"Haaammm.....*Schlop!*..mmnhmmm....! *Schlurppp...schluropp..sschlurpp....schlurpppp!* Mmnhmmm...Master...! *Schlurppppppp...pop!* Ah, there.~" Caster Iris said with a smile, having quickly cleaned him up of all of the remnants of his sperm as well as the moistness of Princess's sex. She was used to doing this all the time back at the Wandering Base whenever Master Ritsuka tended to other Einzbern Servants like her daughter Illya and her friends while having her join in on the fun. Even her maids Sella and Leysritt from her past life joined in on the fun, making for a frenzied four-way of silver-haired Homunculus women getting railed by the same man while also pleasuring each other in between.

Caster Iris looked up at Ristuka with a starry-eyed smile on her face while flashing her tongue, showing the residual pool of sperm she now swallowed into her mouth after cleaning him off.

"Ah, I always love seeing one of my pregnant Servants do that. Now then, get onto your back so I can drop this Succubus on top of you and make an Irisviel sandwich. I want to take her other virginity now too and see you both writhing on top of each other.~" Ritsuka commanded as he watched Caster Irisviel obediently comply by standing straight up and hastily undoing the lower half of her dress with a flick of her fingers. She was grinning eagerly the entire time as she showed off her scantily-clad pussy wearing only a thin white thong to match the Heaven's Dress pristine appeal.

Naturally, she had Ritsuka pull those down as well and unveil her glistening pussy to the world without a shred of pubic hair covering her groin. She giggled once again and casually lay back on the ground, spreading her legs apart and bringing her arms up above her head while waiting for her Master to bring Princess to her now. He licked his lips and went over to grab onto the Succubus by the hips, lifting her barely-conscious body up and guiding her to where she was placed on top of her pregnant, buxom counterpart.

"W-wha....what's going on now? W-what are you doing......?" Princess asked, still confused and partially worn out from having the most intense orgasm of her life by far mere moments ago. She felt the bulbous, pillowy sensation of Caster Iris's tits pressing into hers from below in a sensitive nipple-to-nipple contact that made her increasingly aroused. Even her swollen pregnancy belly acted as a support for the full-figured woman, keeping her legs spread over Caster Iris's sides as she looked over her shoulder to see Ritsuka now guiding his cock over to her with a devilish smile on his face.

Caster Iris grabbed onto each of Princess's shoulders and held her firmly in place in case she tries to go anywhere when it happens.

"Hheheheh, what do you think? Master has a lot of love to give and he's not finished with you just yet. Besides....you can't tell me you don't want that glorious cock inside of you again, can you? I've seen your face when you came and it's clear you loved every second of him blasting your uterus full of his seed.~" Caster Iris called out, making Princess stammer and blush deeply as she refused to acknowledge her claim while watching Ritsuka guide his cock over to the surface of her buttocks.

She didn't make a move to try and escape even though she didn't understand why, but Princess was considerably worried since Ritsuka was eying her buttocks and grabbing onto each dimple of her cheeks as though he chose her other hole to plunder with his member this time around.

'Is he....going to fuck me in the ass!?' She thought in alarm and increasing arousal, feeling her body groove sensually along the surface of her counterpart when Ritsuka called their attention by speaking.

"You two, make out with each other for me.~" He commanded, immediately making Princess feel awkward as she unwittingly followed his command by turning her head back to look into her mirror self's smiling face when feeling her slender fingers gently cup the sides of her chin. Caster Iris also felt a bit awkward since she never made out with herself before, but the woman wasn't going to deny her Master's request and promptly pulled Princess down onto her soft lips for a sweet and intimate lesbian kiss.

*Schlup*!

"Mmnhmhhhmm...!~" Caster Iris moaned softly when wrapping those lips around Princess's equally soft ones, closing her eyes with a smile and missing the shocked look on the Succubus's face. Princess, though feeling utterly thrown by this, saw no reason to refuse and got into it by pulling her arms around the Caster Servant's neck before proceeding to elevate the lip-lock by kissing back. "Hmhmhh...hmmhmm...hmmm...*Schlupp...schluppppp..schlupp!* Ahh...there you go. Now you're getting into it.~"

"Mnnghh....this is so awkward, b-but I can't....get enough...! Hmmhhmhh! *Schlurpp..schlurpp..schlurppppppp!* Ahhh...you taste so good...!~" Princess mumbled into her lips, sliding her tongue along Caster Iris's as they made out feverishly in a wet mess of saliva being exchanged in a pornographic way. It was such a titillating sight for Ritsuka to watch as he saw Caster Iris hungrily swallow Princess's tongue and have hers swallowed in return.

The two women were making out so passionately with each other that lurid, slurping noises were loudly exchanged and their bodies started grinding into one another with the grooving of their breasts. Princess was the dominator in that one since she didn't have a swollen belly containing his offspring just yet, but seeing the two Irisviels run their hands all over each other while Caster slides a leg up around one of Princess's thighs made this incredibly worthwhile.

"Hmmnhmhhhh! *Schlurpppp!* Ahahhhh....more...! I need more....!~" Princess cried out between wet breaths, immediately being silenced when Caster Irisviel swallowed up her lips again in another overly erotic lip-lock that involved drinking her saliva.

'Wow...I know I've paired up other Servant women before with each other for this kind of thing, but seeing what is essentially twin sisters do this is extremely exciting for my libido. I wonder how Princess will feel when I do this...~' Ritsuka thought as he grabbed firmly onto each side of Princess's buttocks before spreading them open and guiding his cock directly into the tight-looking pucker hole that is her anus.

The Succubus was too preoccupied with sharing saliva with her 'sister' to notice at first, but when she felt the bulbous shroom of his cock prodding the rectal opening she looked back and saw the well-hung man plunge it straight in without hesitation.

"Hmphhmh...!~" He grunted and pushed his waist forward, burying nearly a third of his cock directly into Halloween Princess's ass.

*Plop!*

"Gnnghghhhhhh!! *Pop!* Aaaaggnnhhhhhhhh!~" She cried out in pain and ecstasy, pulling her tongue out of Caster's mouth with a dark blush coloring her face and staying like that for a frozen moment in time when Caster decided to assault one of her breasts next since they were pushed in front of her face. 'He's in m-m-m-my.....ass!! Haaggghhhhhhhhhh! It feels...so.....good..yet...it feels like it's splitting me apart too! Oooaahhhhh...!~'

"Mmnhhhh, breasts for me...! Hee hee, I can't wait...*Shlurppppp*...until these start swelling with milk now.~" Caster Iris says between languid suckles of each of Princess's nipples as she took turns nibbling on each of them while she adjusts to having Master's cock in her ass.

"Gunghh....! Ahhhhh......! Ooohhhhh...Master...! Fuck me...! I'm all yours, Master...! Fuck me until the end of time...! I'll gladly bear children for you just as long as you keep filling me full of your love..!~" Princess cried out, now wearing heart-shaped pupils as Ritsuka drove a few more thick inches of his cock into her ass and began bottoming out of her heart-shaped rump like so. He had held onto her hips and kept Princess's bottom firmly pressed against his waist with his balls slapping into the nether region of both Irisviels while beginning to really fuck the Succubus variant.

"Heh, finally won you over. I shall call upon the power of the Holy Grail...and channel all the wishes of the people of the world whether in this Singularity or in reality that want to see me fucking a Succubus into complete submission...!~" Ristuka says, flaunting the Command seals on his knuckle and feeling the Divine power of the Holy Grail surge through him as he was granted that wish to become even more empowered than before to break Halloween Princess Irisviel fully with his cock.

The golden magic of the artifact made his body glow and his cock began enlarging from inside Princess's anus, making her clutch Caster Iris's shoulders for support while she squeezes her teeth together in a delirious smile. Ritsuka groaned loudly as he felt his cock becoming larger and longer with his balls increasing in size to where they practially became the size of tangerines. He could feel his dick filling up the entire cavity of Princess's asshole, making her tongue roll out of her mouth as he began moving once it was done.

"Ummgnh..mmngh..mmngh..mmmghh..mmngh..mmngh..mmgnhhh!! Oohhh..yeahh! Who do y belong to, Princess?! Who...?! Tell me your name and tell me who owns you!~" Ritsuka let out between heavy grunts of pleasure. He was sawing his dick out from inside of the Succubus's tight asshole, repeatedly making pelting noises of skin colliding with skin while her body undulated violently atop Caster's chest.

"Aaaghh...aghh..aaggh...aghh..aghh..aaghh..aghh..aggghhhhhhh! Youooaaahhhh! Master...! It's you! I'm your bitch...! Ooaahhhhhhh! Please.....breed me...! Fuck me like this forever...! Hgnghghghh!~" The woman let out, keeping her head tilted back as her breasts continued to push into Caster's face now that she was hungrily sucking on her nipples in tandem with both of her hands groping them together.

The flesh-smacking noises of primal breeding steadily became rampant and unabundant with Ritsuka not holding back as he tunnels directly into Princess's ass. She could feel the entirety of her anus churning around his cock which was practically plundering the end of her bowels since it was pushing so deep. Princess could practically taste it, even while she was jostling about voraciously atop Caster Iris's body. Her lips morphed into a wide, gaping smile of ahegao nature with her eyes rolling to the back of her head. The woman born from the Halloween Singularity was falling head-over-heels in love with Ristuka Fujiamaru as he thoroughly dominates her body and decimates her ass for minutes on end.

"Gnnghghhh...! Hhaaahhhhh! Uhh..uuhhh..uhhh..uhhh..uhhh...Master...! I'm....c-coming...! I'm cumming soon...yaaaahhhhhh!~" Princess cried out in euphoria, keeping that face going while holding her hands around the back of Caster Iris's head when feeling her rectal muscles beginning to lurch in convulsions! Her pussy started lurching internally too with gushes of cum beginning to spritz out onto Caster Iris's pussy from above as this primal butt-fucking bliss reached its crescendo with a few more thrusts from Ritsuka's hips.

"Aghh..ghh..aahh..aahh..aghh..ghhh! You got it..! I'm about to blow too, Princess...! Here..is your...reward...! Uaagghhhh!~" Ritsuka let out as he plunged deeply into Princess's buttocks, feeling his balls lurch and pulsate before sending a geyser-like blast of sperm directly inside of her anus! At the same time, Princess felt her insides twist with orgasm as she felt the streams of sperm shooting so far into her rectal cavity that some of it was even threatening to gush out of her mouth while she becomes insensate with mind-breaking pleasure!

*Spplutt....spplurrt..spplurrt...spplurt..spplurrt..spplurrt..spplurrtt!*

"Ghaaaaaaaaaahhhhh! Ghglkhjgklhglkghhhh! Master....! I love you soooooo..much...!~ Hehehehehh....*gags...!*" Before she could utter any more words or speak coherently, sperm gushed out from inside of Princes's mouth where Caster Irisviel was waiting so she could leech her share out from her doppelganger's mouth.

Gushes of sperm splashed and gushed from inside of the O-shaped mouth of the Halloween Princess, she remained insensate with pleasure while keeping her mouth open in a frozen ahegao-style smile. Caster Irisviel brought her lips down onto her own again, scooping all of that excess sperm into her mouth and making out with Princess while doing it.

'Hmmm....*Schlurpp..schlurpp...schlurpp..!* Mmhm....that's it, share with me what you can't handle, Princess. Hehehehh...I told you you'd love everything Master gave you. Mmhmhm...*Schlop*....tasty, tasty cum.~" Caster mewed into her mouth, swallowing up the last remnants of their Master's sperm while Princess slowly came down from her orgasmic high and passed out with a spaced-out look of utter contentment frozen on her face.

She slumped over Caster Iris's breasts, allowing them to be used as makeshift pillows when Ritsuka pulled his cock out from the gaping hole of her ass. A sludge of sperm naturally spilled out of it as a result as he stood above the two light-skinned women, admiring his handiwork and noticing that the scenery of the Halloween-themed Singularity was slowly erasing itself from existence. That'd mean they'd be brought back to the Wandering Sea base in no time with their other party member Servant returning as well.

The Singularity was now officially solved, but Ristuka made sure to bend down and scoop up a nearly comatose Halloween Princess Irisviel into his arms to keep her Spiritron body intact when they'd return.

"That was...amazing, Master...! Heheheh, I am certainly glad to have shared this supernatural event with such a pure and frisky 'Sister' today. Are you going to take her back with us as a pet? She'd really be a big help in restoring the population of the planet now that she's keen on birthing your children like all the rest of us.~" Caster Irisviel said as she was pulled to her feet by Ritsuka once he grabbed onto one of her hands.

He held them both there close to his chest, admiring the swollen pregnancy stomach on Caster Irisviel Einzbern and loving the dazed look of blissfulness on Halloween Princess Irisviel as she dripped heavy amounts of sperm from between her legs.

"Heh, like you even need to ask. Of course, we're bringing her back. She's going to be our exclusive pet which I'm sure Illya, Leysritt, Sellan, and whoever else will want to enjoy playing with. I know I will. C'mere, beautiful.~" Ritsuka said as he cupped Caster Irisviel's chin and pulled her onto his lips for a deep and loving kiss she gratefully returned while Halloween Princess simply murmured incomprehensibly with a delirious smile.
