**Chapter ??- BB

***

Back within the Chaldea Base where all manner of Heroic Servants dwell after they are summoned by their Master and who dwell among the rest of the Chaldea crew who are helping to get the world back on track following Operation Grand Order, a certain Mage Hero known only as Shirou Emiya, was busy getting things underway for the three perpetually horny women waiting for him back inside of his bedroom they now share. In and out of consistent romps between himself and the three Divine Servants; Ishtar, Ereshkigal, and more recently Kama, Shirou had been taking care of everyday things for Chaldea’s upkeep, but lately, his women had been clamoring for more of his attention either inside of the bed underneath the bed sheets or outside where he’d have to provide means of sustenance for them. The trio of Divine Deities who are otherwise counterparts to precious women he knew back in Fuyuki, were having ‘cravings’ more often than not these days ever since Shirou first became an item with them. Trying to drain himself of Mana by adhering to their craven sexual desires and unceasing libidos, Shirou decided to go to the Chaldea food court to procure a few trays’ worth of Mana Prisms and Rare Prisms for the girls.

Even though sex with three gorgeous Goddesses with superhuman bodies, unrivaled beauty, and boundless love for him, Shirou felt he needed a small break to cool down his genitals for a bit, hence his trip to the Cafeteria with a chipper smile on his face. All of his Servants were loyal to Shirou, as they would be since he was their Master and provided them Mana with leadership in battle, but his three carnivorous Goddesses who were now his lovers could never get enough. Sexual pleasure from either of them was always fantastic and mind-blowing to experience, but Shirou wasn’t a Servant and he had a normal flesh-and-blood body with a finite amount of stamina.  So he was currently hoping to provide a substitute to those three perpetually horny women waiting back in his bedroom since there was no Chaldea Operation that needs any action right now.

….

“Alright, and here’s another filling meal for myself aside from the grand assortment of both regular and Rare Mana Prisms for the others. It's kinda weird that those three Goddess Servants only ever require Mana for sustenance for the babies. I guess it isn’t like with normal human women, but then again they’re incarnated…which makes this all the more confusing to me. Heh.~” Shirou said to himself as he procured a large tray’ worth of Mana Prisms when he was done.

He was wearing his everyday Chaldea Mystic Code uniform with the white blazer jacket zipped up and the usual pair of dark pants underneath. Normally he’d be bucknaked after going another round with either of the three Goddess Servants who are always waiting inside of his bedroom for more intense ‘Mana-Making’ action, but decency was one thing  Shirou prioritized when walking out in public after an intense marathon of sex. He held a tray stacked to the brim with a pyramid-sized portion of Mana Prisms, these glimmering green cubes filled up with pure Mana for a Servant’s consumption. Da Vinci allowed every Mage in Chaldea a set amount and  Shirou had just maxed out his load for the week in hopes of staving off the severe drain of his balls. He always thought Ishtar and Ereshkigal were bad enough in their own right, but Kama was far more carnivorous and devious when it came to seducing Shirou using her larger breasts and curvier body to keep him in bed.

The woman was so much like a Succubus that it was almost scary and it was twice as potent an arousal factor since she wore  Sakura’s face. 

‘Hopefully ,these will sustain those three.  Ever since finding out that I got them pregnant, which normally shouldn't be possible for a Servant unless they’ve been incarnated somehow, they’ve been at it with me almost non-stop. I need a break, if only for a few minutes if nothing else. I can’t believe I’m actually saying this, but I’m hoping Da Vinci and Chaldeas drop a new mission in our lap right now. I’ll take life and death adventuring over fighting to survive another round of vitality-draining sex with those three. Heh, I can’t believe  I’m complaining about having too much sex, but then again, any other man would've died ten  times over since they’re Servants with the powers of Goddesses.’ Shirou said to himself as he finished stacking up his own personal order of food on a separate tray.

Nodding to himself as he assessed the proper amount of Mana he felt would be enough for the trio back in his room, Shirou picked up both Trays by hand and started walking out of the cafeteria. There were a few members of Chaldea here as part of their thriving Skeleton crew who made things around the base operate to full functionality, including Servants who wanted to pass the time being useful to Chaldea outside of missions. Little did he know that he drew a pair of violet-colored eyes to him after leaving the Cafe and those eyes belonged to a rather mischievous Servant who was freshly summoned during the last mission about a week ago.

“Hee he hee…showtime.~” She said to himself in a gleeful voice and quickly camouflaged her presence using a Magecraft spell before following Shirou out the door. ‘Ooh..! Now’s my chance to make you fall in love with me….and record it all for live stream viewing on my special channel, Emiya-Kun. You’ll have so much fun watching me work this wondrous body of mine to your liking and thereby driving your libido crazy with lust for me. I can hardly wait..!~’

She followed him out till reached a certain point in the hallway where he paused as though he sensed something behind him. Shirou halted in his advance and slowly turned his head just as his mysterious stalker was about to reappear right beside him with a pair of gloved fingers elegantly twirling a conductor’s wand in her right hand.

“Hmmm….something feels off. I sense something, this can’t be another thing like with Kama, could it?” Shirou quietly said to himself as he slowly turned his head, becoming alert and feeling ready for a fight till there was a gentle glow of violent Magical energy hitting him in the back of his head, making him sleepier with each passing second. “Nnghh..! What the…? Mnghh..! What’s going on…? I’m…getting sleepy now….damn it..! I was too late…”

He felt weak and slumped to the ground against the nearest wall, dropping the two trays of Mana Prisms and food respectively as his vision faded. During the last few moments he regained consciousness, Shirou saw the face of his mysterious ‘attacker’ as she appeared before him with a sweet smile on her face, one filled with a mischievous and self-serving attitude. She revealed herself to be a very busty, purple-haired young girl with long hair that reached all the way down to the back of her ankles. She had bright violet-colored eyes and a continuous smirk on her face at all times for she was giddy with glee in causing trouble for others as well as having fun in the most chaotic ways possible. She was a bit shorter than Shirou and was wearing a long black coat over her shoulders with a matching mini-skirt underneath that completed the ensemble of a kind of uniform since she had a white shirt underneath which brought out the fullness of her breasts. Her mini-skirt was so short and hiked up that it revealed the white of her panties from between a pair of stocking-clad legs which were elegant and long, matching her graceful yet arousing appearance. In the left side of her head there was a red ribbon tying her hair back a bit only from the side, giving her a unique appearance aside from the fact she was also a Servant materialized with the same physical features as someone Shirou knew. In this case, it was Sakura Matou, but this incarnation of her was a Special Servant from the Extra Class known only as ‘B.B’ and she was twirling her conductor’s rod around between her fingers as she stood over Shirou with a sadistic look on her face.

“Alright, Senpai, it’s time you and I have a little fun. I’m going to give you a special performance indeed, one that you’ll love so much you’ll have to make me part of your harem. Hee hee.~” B.B. said with a giggle of excitement as she rubbed one of her shoe-covered feet into Shirou’s crotch before whisking her wand aside to teleport the Trays of food over into his bedroom so that his lovers don't come looking for him anytime soon.

….

**

Waking up, Shirou’s head felt like it was whirling when his vision came back to his consciousness. The young ginger-haired Master of Chaldea had awoken from inside a dimly lit, lavender-colored bedroom somewhere he didn’t recognize, but it was too dark for him to see properly as there were no lights on. He could only figure out that he was bound from inside of a chair with his wrists tied back behind it with a Magecraft spell of binding. He was still in his Chaldea uniform right now, but he had a feeling this was going to be something similar to when he had given into his lust and carried a very horny Kama back to her bedroom for a heated romp. 

‘Nnnghh….this feels familiar. Uungh..where am I this time? I believe I’m still in Chaldea…but I--’ Shirou’s line of thought was cut off when all of a sudden several stagelight lamps lit up in rows of three side by side from around a circular platform with a long silver dancing pole stationed in the center. Behind it was a runway dotted with glimmering lights and a stage curtain set with two letters shown on the fabric which identified who it might be that had taken him here. ‘Oh no, this couldn’t be….her doing, could it?’

“Thaaaaaat’s right, Senpai…! It is I, B.B., here to welcome you to a wonderful first-time-in-your-life event solely exclusive for you! Hee hee..!~” B.B., the Moon Cancer Servant who was another alternative version of Sakura Matou, called out from within the speakers on the stage. The stage lights started flickering in a side-by-side pattern while her theme music played in the background, giving Shirou a reason to make a deadpan look appear on his face.

‘Yep, that’s B.B.-Chan alright. Only she could be this extravagant with theatrics, and I’m guessing the ‘special event she spoke of…..is seducing me, isn't it?” Shirou asked aloud to himself and heard only a trilled giggle coming from behind the curtains of the stage which were slowly opening up to reveal the famed Servant in question as the stage lights rotated themselves to focus on her.

“Correct again, Senpai. I’ve brought you here because I was getting sick and tired of watching you have all that fun to myself from another timeline. I mean, it's kinda unfair seeing another ‘Sakura Matou’ getting to have you fuck her religiously alongside those other bimbo Goddesses, you know. Hee…seeing it all upfront in HD real-time visual thanks to my Magecraft and special abilities was one thing, but getting to experience it is another thing entirely. Watching it just doesn’t compare to the real thing…so I decided to ‘invite’ you here so that I can swing my way into your little lovenest. I mean, you’re giving it out to all three of those Divine Pseudo-Servants, aren’t you? Why not invite the beautiful, cute, and ever-so-charming B.B. into the mix, Senpai?~” Her voice rang out again and Shirou was left nervously chuckling for he hadn't considered that his other female Servants, such as B.B., would’ve wanted to include themselves at all into this bizarre love life he had with his Servants. He was still wrapping his head around creating long-term plans with each of them now that they were pregnant with his babies, including Kama herself, but Shirou hardly had time to think due to how often each of these Succubus-like Servants gets dragged back into bed for more sex.

His wiener felt drained just thinking about it, but it perked to life when he saw B.B.’s shadow step forth from between the curtains to present herself before him and she was wearing her Fully Ascended ‘Luluhawa’ Spirit Origin outfit which was a classier and sexier variant of her original one. 

“Senpaaaaaaii…! Like what you see…? I’m sure you can guess why I had this stage set up and materialized inside of my room, but just in case you’re still processing all of this, I shall tell you I plan to woo my way into your pants by performing an erotic dance using my skills. And I’ve got quite a lot of them ready for you, Senpai.~” B.B. greets in a whimsical, lust-filled voice as she arrives wearing only a skintight white one-piece swimsuit around her torso, nothing over her legs except a pair of red high-heeled shoes around her feet and her Vampiric overlong cloak worn around her shoulders. Her white magician’s gloves were over her hands as always along with her trademark ribbon in her hair, but Shirou seeing her now exotically push out her pelvis toward him after grinding her backside into the silver dance pole behind her made his attention get snap-locked onto her body. 

She was suddenly far more voluptuous and alluring than in the last mission he Summoned her to take part in, now he couldn’t take his eyes off her boisterous set of hefty G-cups just bouncing around salaciously from inside of that white top of her outfit. B.B. 's long legs were smooth as was the rest of the soft flesh encasing her body, making Shirou begin to grow hard as the Mooncancer Servant now started spreading her legs outward while thrusting her pelvis gently in front of his face. The tempo and beat of the music changed into something more exotic with a bit of B.B. 's personal theme music mixed in, creating an atmosphere reminiscent of a dance club.

“B.B.-Chan…! Ngghhh! You know…you would have just asked..! Ugghh! I wouldn't have said no to you….b-but I’d still have to okay it with the others..! I mean, you and Kama-Chan both share a similar origin just as you do share a similar host..aangh! It wouldn’t have been impossible or necessary to kidnap me..! Mnhm!~” Shirou moaned with every word coming out of his mouth as he watched B.B. now swing her hips voraciously in a sideways angle, matching her movements with the beats of every note in this song just to further entice Shirou into wanting to fuck her savagely as she planned.

The Servant started gyrating her hips around in circles, keeping a gloved hand held onto the pole from behind and letting the other one fondle her tits through her white top, doing so virulently and graphically that it made Shirou whimper even louder than before. He was still very sensitive from all the back-to-back sex with Kama and the others, but for some reason, he felt as refreshed as though he’d gone a week without sexual stimulation. 

“Aanghh..! Also..what did you do to me..? Did you use a Revitalization Spell…on my genitals, B.B.-Chan….?” Shirou asked, whimpering with each word coming out of his lips as his eyes followed the circular sway of B.B.’s boisterous tits just jiggling around. She kept her movements consistent and graceful, matching the rhythm of the music as she wriggled her hips sideways in a provocative manner before alternating into a different dancing rhyme.

 She turned around and flaunted her supple and plump, heart-shaped ass before Shirou’s face before crouching lower to the ground and putting her gloved hands around each of her kneecaps. B.B. cast a coy look at him from over her shoulder while pushing her hips out even more so that more of her ass reached the airspace just above Shirou's face. He winced visibly with arousal and felt this cock becoming hardened already, to the point it nearly tore through his trousers while B.B. simply answered him by propping herself on her hands and beginning to twerk her buttocks right in front of his eyes.

“Ha…ahh…aahh..haah…hahh…aahh..! Senpai..! Are you enjoying my dance right now? All I’m doing is shaking my ass right in front of your face and it looks like it’s having a profound effect on you..! Hee hee…are you wanting me to strip your body of clothing and begin riding you right away, or would you prefer that I continue my dance routine so that you’ll come at me like a mad beast?~” B.B. said with a playful tone as she wriggled her thighs side to side, causing her buttocks to jiggle more boisterously while the white of her one-piece swimsuit rode up even higher between each cheek of her ass. Shirou could see the moistness of her groin becoming more noticeable as she swirled her hips around in circles while pushing out her buttocks in and down movements of hip-bobbing motions. “Mnnhhmhhhh! Mh…mh…mmh…mh…mmh..nnhh….! Senpai..answer the question for me. I want to know what you like more.~”

“Nnghh..! I want…you to keep dancing..! Unghh..! B.B.-Chan..!” Shirou answered with a whimper, making B.B. smile coyly as she turned around again and grabbed onto the pole with both hands before bringing herself up to deliver a sideways split with her long legs. One of them rode up the shaft while she ground her pubis into its polished, metallic surface, and the other simply remained hooked around its side as she twirled around on it in an erotic fashion. ‘Guguuughh! She moves with such grace and that tight outfit of hers is making every part of me scream out of her with lust on the brain.! Guuuhh…! And here I thought Ishtar and Kama wearing their skimpy everyday outfits was enough for me…! B.B-Chan takes it to a whole other level….!’

Shirou felt his cock hardening more and more till it was painfully pushing against his trousers while watching B.B. dance around the pole erotically and fluidly. She did every twirl with grace, popped out her hips in a dynamic manner matching the rhythm of the music playing, and even fondled her breasts within each of her hands when getting down on both knees to pose for him as though she was some lioness on the prowl. She knew every move to make to further Shirou’s arousal and her strip dance routine went on till she started lowering the cups of her one-piece by magically detaching part of it from behind. She still had her collar on around her neck and her overly long coat had already dispersed into Spiritrons at this point, leaving only the bottom half of her tights with her white gloves and high-heeled shoes worn around her body at this point.

“I can see you’re getting ready to burst, Senpai. So how about I…continue on to the next step? Hm?~” She playfully asked as she gracefully hopped off the stage, placing herself between Shirou’s legs and spreading them out with two of her fingers pinching the zipper of his pants and pulling it down. “Ooooohh..! Senpai..!~”

Out popped Shirou’s member in fully erect form, it had slipped from inside of his boxers and pointed outward toward the woman’s face with thick, swollen balls teeming with rich life force within. B.B. honestly shuddered with great arousal upon merely seeing it up close and she made her tongue circle around her mouth with desire while casting a look of excitement at Shirou from below.

“Mmnhmm! Seeing it in action really doesn’t compare to having it before me, up close and personal….ugguhhh! I can’t wait, Senpai, but first…..I think a little more ‘dancing’ is necessary to really excite your engines. And it’ll all be broadcasted on Channel B this evening for any willing Servants wanting to watch Senpai get down and dirty with yours truly…!~” B.B. announced with her dynamic flair for showmanship as she pointed to several hovering Magecraft-Tech cameras that displayed the entirety of her bedroom on Chaldea TV. Her usual violet hud and television show display appeared on everything on a border surrounding the image of Shirou strapped to a chair with B.B. fully pulling out her lush G-cup-sized tits for his enjoyment. “Like these, Senpai? They’re all big and juicy and perfectly plump as you prefer. I think only Kama-Chan has me beat, but I like to think my cuteness overrides her blatant nakedness any day of the week.~”

B.B. said this while fully revealing her tits and cupping them within her gloved hands. She jiggled them around playfully in a gyration motion while Shrou just watched with growing arousal burning up his body.

“Gnnghghh! W-w-wait a minute..! Did you say we’re being broadcast live..!? And on your channel…? W-who knows about this..! Guguh..!~” Shirou groaned, unable to tear himself away from admiring B.B. 's lush boobs as they swiveled around in circles from inside of her hands for another few moments before she turned herself around again. The Mooncancer Servant chuckled flirtatiously and gave him a cutesy wink from over her shoulder as she propped herself up between his legs by pushing her buttocks up against the underside of his dick. 

Between feeling his dick getting smoothly worked on by B.B.’s large, supple buttocks and looking around to see if there were any of her special cameras recording all of this, Shirou’s mind was boggling with lust right now due to the elevation of the woman’s smooth posterior sliding up against it. She raised her hips slowly while keeping her legs propped and spread as a professional lap dancer would do. B.B. kept a gleeful smile focused on him from the side as she eyed him from over her shoulder, enjoying the myriad of reactions his face was making as she continued swiveling her ass around in circles underneath his cock. 

‘Ooohhh! He’s positively twitching now..! Eeee…! Senpai must be enjoying my amazing dancing skills, more so my buttocks and it feels underneath him. He’ll be ready to pop and mount me like a lion sooner than I thought.~’ B.B. thought to herself with a smile and sensually undulated her body in smooth curling motions to put more emphasis on her ass and hips. The latter would rise up high as she kept her gloved hands around her kneecaps, pushing out her buttocks even more to where the grooving motions Shirou was feeling by having his dick between her ass would feel better. “Unh..uuh..unh…mnhmhmmmm! That’s right, get aroused for me, Senpai..! Heheheh…! Your dick is enjoying what I’m doing so much, are you feeling ready to explode all over my back then? I’m wearing the swimsuit variant of my usual outfit so you can see my smooth backside and part of my ass for your enjoyment, you know.~”

B.B. croons softly with delight as she reaches back to tug her long mane of hair to the side to expose the smooth surface of her back to him, showing that much of her swimsuit outfit only covered up her chest and concealed her ass at all. The crack of her buttocks was there underneath Shirou’s length, gingerly bouncing it along the creamy valley between her cheeks as she took turns wriggling her hips side to side slowly. 

“Aaanghh! Fuck…! B.B.-Chan..! Nngghhh..! Your butt….is so…perky..and supple…! It's driving me crazy…!~” Shirou groans loudly as his cock pops up and down between the girl’s perfect ass, feeling the smooth surface of each cheek caressing both sides of it as B.B. starts rowing her frame back and forth to press more force into her hip-rocking motions. She was effectively twerking underneath Shirou’s cock and feeling it twitch angrily with desire for her the longer this went on. He held his hands around the sides of the seat he was in, feeling anxious to fuck her already yet Shirou could barely look away from the girl’s heart-shaped rump for more than a second as she continued her butt-job for another couple of minutes before switching tactics. “Mnnnghhhmhh..! B.B.-Chan….! Uunh..uhh..uuhhh…uhh..you’ve got such a nice ass, heheh..! Nghnh!~”

“Hee hee, I’m glad you like it, Senpai. Mnh..nh..nnh..mmnhm…mnmm! Now… let's push it even further, hm?~” B.B. teases with a smirk as she props herself up a bit more then pushes her ass back even further so that it would bend back Shirou’s cock just a bit to the point it was pointing upward. He visibly winced in slight pain for he was so hard that this hurts his erection a little, but the pain added an unforeseen spice to the mix as he had felt B.B. 's ass more fully. Her lush butt cheeks were so full and ample that they hotdogged the man’s shaft while B.B. merely stood up in a squatting manner, putting her hands behind her neck as she began working her ass on his cock even more fluidly than before. “Eeyaaahhhh! Nngh..mmhm..mmnhm..mnhm..nmmnh..mmnghh! I can feel you sliding that thick dick up from between both sides of my ass, Senpai. You’re enjoying this so much and probably want to fuck me now, don't you? Say it for B.B.-Chan now, say how badly you want to drive that dick inside of this fertile ‘Goddess’ of the BB Channel.~”

Her rump came up faster and slid more enthusiastically than before with B.B. keeping Shirou’s length sliding up between the cheeks of her ass. She was keeping a steady pace of working her hips energetically so that he could feel every part of her flesh smoothly stroking his. It excited her too, making her even more aroused than she was already as she raucously popped her hips up and then squatted downward in a perpetual motion of a grooving pattern. 

“Unnhhghhgh…yess..! I love it..! I want to have you right now..! Aaghh! This is more torturous by definition since you’ve got me bound here, B.B-chan..! Aaahh..uuh..uhh..uhh.uhh..uhh..mghgmm!~” Shirou growled loudly as he felt the Servant’s buttocks groove down his shaft then back up again to the tip for a staunch fifteen minutes till B.B. felt anxious to move on to the next step of her seduction plan. Shirou was already pent-up enough and ready to blow thanks to her dancing and butt-twerking lapdance on his dick, now she wanted to feel Shirou’s body more intimately and that idea continued with a bit more foreplay as she slowly moved her ass away from his cock and turned around.

Shirou’s eyes stayed on B.B. the entire time as he saw those globulous breasts of hers jiggle around with her dainty body, making his cock lurch strongly with arousal once again when she got down onto her kneecaps with each gloved finger clutching her tits firmly with a smile. 

“Now it’s time for me to use these to drive you crazy, Senpai.~” B.B. said maliciously with a playful smile on her face as she took each of her tits into both hands, gyrating them around in sensual circles for show before bringing them around to smother both sides of his cock. He instantly feel the difference when B.B. 's mounds squished together around his member fully, or at least as much as she could due to his size being just as great in terms of length. She had full tits the size of her head just like Kama yet Shirou’s manhood easily dwarfed what would be considered ‘normal’ in terms of standard length. He was far thicker than she was expecting yet it was making her more excited to fondle both sides of his shaft with her tits, keeping them smoothly pressed together as she began sliding them up his shaft and then back down again.  

“Hmmnhmhhh! Oohhh..yeah..! B.B.-chan…! Nmnhmhhh! If your ass was one thing, then your tits are another and they’re a league above..! Uuunhh! Not even Kama-Chan can make me feel this good using her breasts, which is ironic considering both of you are Pseudo-Servants with the same host..gaaaaahh!~” Shirou was cut off from speaking any further when feeling B.B. beginning to rotate her melons around in swiveling circles along his shaft. She was grinning excitedly and briefly flashed a wink toward an unseen camcorder as everything going on inside the room was being broadcast on her BB channel.

‘Hehehehe, that’ll get me more funding for sure. I just know that a lot of female Servants in Chaldea will pay top QP or send Mana Prisms to my room from now on after they’ve got a load of Senpai in action. To seduce Senpai is just another bonus, one that’ll make this Servant all the more delighted to share in his love nest. I’d love for Senpai to breed me right beside Kama-Chan and the others. It’ll be such delicious debauchery and romance that I always wanted, but it’ll also make for quality Television on my channel. Win-win..!~’ B.B. thought to herself as she started sliding her tits upward even faster, keeping her torso wiggling sensually to accelerate her movements. “Mnh..unnh…nh….nh..unh..uunh..unnh..unnh..! Senpai…! Your thing is sticking out angrily in front of my face and I think it wants a kiss while my ‘girls’ are busy giving it a massage. Hee hee, shall I let it into my mouth?~”

All she heard was just yet nother billowing groan of elation coming from Shirou’s lips as he wriggles around inside of his restraints in the chair while his hips buckle outward with a primal desire to fuck her already. He was gritting his teeth and feeling every ounce of strength come forth to try and break free from his restraints, but they were a special Magecraft only B.B. was capable of using and that meant he was stuck there till she said otherwise. The girl delighted in her borderline sadistic approach to worshiping his cock while he was unable to grab her body and fuck her. B.B.’s lush and voluminous tits started squishing themselves together around his shaft as closely as they could while she began pumping her chest forward with much more rhythm.

“Hhnnghghhhh!...Let me out..! B.B.-Chan..! Mnghh! This is too much…! I’m going to explode soon…aaannghgh!~” Shirou cries out in blissful agony and hearing him only made the Servant accelerate her actions. She was practically huffing and moaning quietly with excitement as her tits started sliding faster back and forth along Shirou’s bulging shaft. 

“Hah..hah…ahh…ahh..hah…ahh…haahh.yes..! That’s right, cum for me, Senpai..! Mmh..mnh..mnhh..mmnghh! I think giving it a little kiss will help do wonders for that magnificent libido you have! I’ve watched him mount Kama-Chan and those two bimbo Goddesses again and again after you’ve been driven to the brink…! Mnghmm…say ‘ah’ for me…aahmmhm…slrrpp..mmhm!~” B.B. followed up by enclosing her lips around the bulbous cock-head tip of his penis. She kept her tits heaving closely together around the top half of his shaft, allowing the tip to be pushed out enough for her to be able to reach. B.B. had craned her head forward and engulfed the tip of Shirou’s length into her mouth, moaning warmly around it while her tongue started flicking itself all over the surface. She had begun sucking him off in earnest while also flicking her tongue around it, keeping her breasts pumping slowly all the while.

Naturally, this drove Shirou insane with sexual desire for he had B.B. after she had begun weakening her concentration on those bonds keeping him strapped to the chair. 

“Mmhmmh..sllrupp..sllruppp..shlrupp..mmnhm..mmhmb..mmhmb..slrupp..shlrupp...sllrruppppp..mnhmm! Senpai..! Show me much how you like this..and how badly you want me right now.~” B.B. encouraged as she saw his member twitching angrily from between her breasts, figuring now was the time to bring him home with one final action that’ll lead them to fucking like wild animals atop the bed. ‘He’s ready.~’

“Yes..! Give me a chance and I will..! Nnghhhhh! I think I’ve been teased long enough, B.B.-chan…aaaahh!~” Shirou howled and saw her sliding her tits down to the hilt of his shaft, keeping them smothered firmly around the lower half while she allowed more inches of his dick inside of her mouth. This time, B.B. was eying Shirou with a lusty bedroom gaze as she slowly drew out her tongue and let it slide sensually along the tip of his cock and all around the upper half till he was ready to explode. His balls tightened up and Shirou let out one last groan before suddenly feeling his hips spasm with ejaculation just as she planned. “Aaaaaghghh! Fuck..here…! Nnghh!~”

‘Yay..!~’ B.B. thought to herself with gleeful delight and squeezed her tits together one last time before opening her mouth fully to accept all of Shirou’s thick cum. 

Spplrrt..spplrrt..spllrrt..spllrrt..spllrrt…spllrrt…spllrrt…spllrrt!

Long, thick ropes of sperm flew straight into B.B. 's mouth right when she had her unseen Cameras zoom in on the messy display for her show. Every woman and female Servant watching her channel right now were in awe of Shirou’s semen capacity as there had been so much flowing into the woman’s opened mouth while some strings of sperm landed directly across her face and chest. 

“Yessss…aaaahhhh! Senpai…gulp…gulp…...mmnhmm!  You’re cumming so much because of me..! Mnhhh! Let me bathe in all of it..!~” She cried out and closed her eyes with a mirthful smile of amusement on her face as the deluge of sperm kept going for at least another minute until he was done.
