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 Irisveil-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.
