Beatrice, the Great Spirit of the Forbidden Library, had lived a life in simple routine. Her days were spent reading, or re-reading, the various books within the library that she guarded. As she was part of Roswaal's mansion, occasionally he would have some need of her assistance and send his maids to come and find her. Events such as this were irritating to her, and whenever she was pulled away from her normal routine, she found herself in a rather bad mood. The only thing that gave her any real joy was spending time with her beloved brother, Puck. Each day was the same as the last. To a being of Beatrice's age, the days, the months, and even the years blended together. Decades of isolation. Centuries spent waiting for That Person.
Yes, that was her purpose. To guard the knowledge contained within the Forbidden Library, and wait for That Person, who would come and take her out of the library, the one who would free her. After hundreds of years, she had given up hope. But her patience, all those years of loneliness, had finally been rewarded, when her world was shaken by the arrival of a seemingly ordinary teenage boy.
To describe the boy known as Subaru Natsuki as That Person would be to do him a disservice. Every hope and dream, every thought Beatrice had ever had about That Person, was utterly eclipsed by the reality of what Subaru had given her. He was much more wonderful than anything she could ever have imagined.
Her most fond memory was the day she realised who her destined one was. It should have been just another day, but Beatrice had sensed strange things going on in the mansion. As a creature of an unchanging routine, and being so directly connected to the mansion in which her Forbidden Library dwelled, she was extremely sensitive to any deviations from the norm. While the specifics were lost to her, she had sensed subtle dark magics working throughout the mansion. It was a feeling similar to what one would expect from a witch. It hadn't been uncommon as of late to sense dark presences like that. Subaru had absolutely reeked with the scent of the witch on occasion, and Beatrice suspected that whatever was going on, Subaru was in the middle of it. It was something for her to keep an eye on, but she wasn't the type to take action unless necessary.
She did become temporarily concerned when she felt a huge surge of mana from Puck, but it only lasted a few seconds. Shortly after that, he communicated to her from afar, telling her not to worry, and that it wasn't something that she needed to concern herself with. Following that vague message, she was satisfied. If Bubby was involved, she would leave things to him. She still had an odd feeling nagging at her, but any time she reached out to try and sense anything, she found that her deeper perception was being blocked by Bubby. She thought it was definitely strange.
It wasn't long after that that the doors to her Forbidden Library burst open, and Subaru Natsuki appeared before her. The boy was usually a source of annoyance for her, but somewhere deep down, she did find herself enjoying his presence. Sometimes. She braced herself for whatever inane ramblings Subaru would force upon her today.
Beatrice had looked up from her book, into Subaru's eyes. He flashed his usual grin and opened his mouth. He told her, his words resonating with power, that he owned her. That Beatrice was his loyal, adoring sex slave, and that every single hole on her body belonged to him.
…
Well, that was obvious. She wondered why he felt the need to say such a thing. Of course Subaru was her beloved master. He owned her completely, and she adored him in turn. That was just the way things were.
She was happy from the bottom of her heart to be owned by him, but there was something slightly off to her. It really was just common sense that Subaru owned her, and was the one to finally free her from her despair. But she had known him for around a month at that point. She remembered still fretting over the question of whether he might finally be That Person, and still feeling the anxiety that came with not knowing, her Tome of Knowledge long since empty. So why was she just now realising something so obvious? She couldn't put her finger on it, but the whole situation seemed somewhat strange. It didn't matter though, and she put it out of her mind for the moment as Subaru approached her. He owned her body, and she knew it. He took her first time right then and there, and introduced her to a world of unimaginable pleasure. They forged a contract thereafter. Already belonging to Subaru, it was more of a formality, but it still felt wonderful to be officially tied with her master.
A truly wonderful memory. Beatrice gripped the book she was reading more tightly, feeling her loins starting to stir at the memory. Honestly, if she had her way, she would be by Subaru's side at all hours of the day, servicing his cock or doing anything else he required. She would be his personal footstool if he asked it of her. But she also understood that, for all his greatness, he was still only one man, and he had other sex slaves he needed to keep company. She used to only be friendly towards Puck, but Subaru had encouraged her to become friendly (and sometimes even intimate) with the other members of his harem. It was only right that her master owned other women the way he owned her. She thought back to another memory, when she was reintroduced to the other women living in the mansion.
It had been the following day after Subaru took her virginity when Beatrice discovered that all the other women in the mansion were also Subaru's sex slaves. And not just the women in one case. Puck had altered himself to become a girl and joined the ranks of Subaru's sex slaves. Beatrice had watched with jealousy as Subaru took the twin maids, followed by the half-elf. But when Puck started rocking her hips against Subaru's, staring into Beatrice's eyes and extolling the virtues of their master's cock, Beatrice had that uncomfortable feeling welling up inside of her once again. The other women were one thing, and she really didn't care what they did, but seeing Puck, her beloved Bubby, turned into her master's plaything, made her freeze up.
Something about the whole situation seemed off to her. Subaru was her beloved master, and she would never speak up against him or do anything to displease him, but she couldn't shake the feeling that something was very wrong. It was so out-of-character for Bubby to do…that kind of thing. When it finally came around to her turn to be fucked, Subaru noticed her distress, and with a booming voice, explained to her that it was perfectly normal for him to turn anybody he wanted into his sex slave, and have them join his harem. Beatrice had cursed her own idiocy for forcing her master to explain something so obvious. It would end up being the last truly negative thought she'd ever had.
Since then, she had lived her days out blissfully. Her master would visit her frequently, and sometimes at his behest Beatrice would join the other girls together. She especially loved doing it together with Bubby. They had always been close, but when Master fucked both of them, it made their bond feel extra special, because they were sharing something so amazing.
Beatrice sighed into her book, closing it and placing it aside. She didn't want to seem needy, but she had managed to get herself all worked up. She would go and see if her master was available. She would be willing to beg if she had to. She used to be so proud, but if it got her master to fuck her, she would do anything, no matter how degrading. She readied herself to leave, when she sensed the presence of someone coming down the hallway outside. Hm, she supposed it was about that time.
A knock sounded against the door. Beatrice's door crossing spell had been disabled quite some time ago, as Subaru had explained to her that it was important for the other girls to be able to speak with her if they wished. Someone knocked on the door once again, and Beatrice magically opened it, revealing the small form of Petra Leyte, the youngest of the maids employed here. Well, it wasn't really accurate to call her, or any of the maids, employees. They were paid, but the money was almost useless to them. They only had one ambition, after all.
Petra gave Beatrice a wide smile and waved to her. "Good morning, Beatrice!"
The old Beatrice, the Beatrice who knew nothing of the wonderful life of a sex slave, would have bristled at the casual tone with which the girl addressed her. But now she didn't mind. Beatrice wasn't in any kind of position of seniority that mattered. All of them were equals as perfect, loyal sex slaves to their master.
"It's not necessary to visit every single day, I suppose."
"Well, I'm trying my best, so I wanna know as soon as it happens!" Petra responded with her usual enthusiasm. "And besides, I like spending time with you!" Petra wrapped her arms around Beatrice, embracing her in a tight hug. Beatrice awkwardly returned the gesture, lightly patting Petra on the back. At her master's behest she had gotten a lot closer with the others, but she still wasn't entirely used to it. The gap in her love for Subaru versus the rest of the women in his harem was an extreme one.
"Okay, Beatrice! I'm ready to do this!" Petra threw up her index and middle fingers in a V shape, just one of the many strange gestures she had picked up from Subaru. Beatrice focused, and moved her hand over Petra's stomach, her hand glowing gently with magic.
This was the primary reason for Petra's daily visits. The other women in the mansion were a few years older than Petra (with the exception of the relative newcomer Meili, who Petra and Subaru had recently seduced into Subaru's ever-growing harem) and were all pregnant with Subaru's child. Petra had been proactive in trying to get pregnant herself, but her periods had only started a few months ago. Her body just hadn't been ready. Since they started, Petra had come to Beatrice every day to get her to check if she had been impregnated yet, and every day she left disappointed.
Like always, Beatrice searched, reaching out her magic within Petra's body, searching for signs of life. But this time was different from usual. This time, she was met by a faint presence, alongside Petra's own lifeforce. It was faint, and extremely small, but it was unmistakable. Petra had life growing within her. Beatrice pulled her hand back, and smiled up at her.
"Congratulations are in order, I suppose. You're finally bearing Master's child."
The pure, radiant joy that spread across Petra's face managed to stir even Beatrice's heart. She knew how hard the girl had been working towards this goal, and she was truly very happy for her.
"I- I have to tell Subaru! I have to tell him that I, that we-" Petra stammered, barely able to contain her excitement. She turned suddenly and sprinted out the door, yelling an exuberant call of thanks back towards Beatrice.
"Hmph. The least she could do is thank me properly." Beatrice mumbled to herself. It was all an act though, she could easily understand Petra's excitement. It would be best to follow her. Subaru would surely be happy himself at the news, and it would be nice to bask in their shared joy.
Petra was zooming through the halls at a rapid pace, but with teleportation magic it was a simple matter to follow her. She teleported outside the room their master was currently staying in, just in time for Petra to burst through the door.
The scene inside the room would seem utterly outrageous to a stranger, but it was just business as usual for Subaru. He was sitting on the edge of the bed, with two eager heads working away at his cock, tongues running all over his length. One of them had long, black hair and a curvaceous figure, while the other was the opposite, the small figure of a child, her blue hair tied back in a ponytail. They were two of the more recent recruits to Subaru's harem, Elsa Granhiert and Meili Portroute, two former assassins, now both content with a happy life serving a greater purpose as Subaru's sex slaves.
All involved were naked, of course. Beatrice's gaze wandered enviously over Elsa's large breasts, before moving to Meili's almost completely flat chest, tiny breasts just starting to blossom. An adult woman and a child. You could never say that Subaru's harem lacked for variety of body types. This was a good thing. Beatrice was glad that Subaru enjoyed having sex with children whose bodies were still undeveloped, although at four hundred years of age, almost everybody seemed like a child to her, so there wasn't much difference. That said, she could recognise, much to her consternation, that objectively, she herself had the body of a child.
To most people, someone with her body type was of no interest to them, and those that were interested were the dregs of society, outcasts utterly lacking in character. Subaru was different. Her contractor, her master, was the greatest man in the world. And she was so unbelievably happy that he was so open-minded as to be able to enjoy her body without reservation. She didn't even want to imagine a world where Subaru wasn't attracted to her, if he had no desire to make use of her body. It was just a passing, idle thought, but it made her stomach twist into knots. She shook her head, recognising the foolishness of contemplating an impossible worst-case scenario. How could she think about things like that when her darling master was right in front of her? She watched in jealousy as Elsa and Meili took Subaru's tip into their mouths, doing their best to kiss each other in the process, only succeeding in slobbering all over his length. Beatrice could feel herself start to moisten at the sight of her master's cock, but the ongoing proceedings were interrupted when Petra tackled Subaru, knocking him down onto the bed.
"Whoa!" Subaru yelped in surprise. "Petra, wait your turn! I was just about to-"
Petra silenced him with a kiss, slipping her tongue inside his mouth and embracing him passionately. Normally Beatrice would have scolded the girl for interrupting words from their master. But given the circumstances, she supposed it was forgivable to overlook it this time.
Petra pulled away, her eyes shining with happiness and welling up with the beginnings of tears.
"Master…" she sobbed. She sniffed and cleared her throat, trying to compose herself, looking deep into Subaru's eyes. "Subaru. I'm pregnant!"
Subaru immediately stood straight up on the bed, then picked her up by her shoulders and started swinging her around in a circle. "Hell yeah! That's incredible, Petra! Congratulations!"
Petra's tears began to flow freely. "I've been trying for so long!" she wailed. "Finally! I'm finally going to have your baby! I love you, Subaru. I love you!"
"I know how hard you've been trying, and it finally paid off! You're such a good girl, Petra!"
The two girls kneeling on the floor didn't appear to be upset that their worshipful double blowjob had been interrupted, both of them applauding politely and watching the scene with happy smiles on their faces. Meili was the first to speak up and congratulate the pair.
"I'm happy for you, Petra. You and Sis are both pregnant now." She looked down to her stomach, rubbing it longingly. "...I hope it'll be my turn soon."
"Congratulations, Mistress Petra. You'll make an amazing mother." Elsa said. Subaru's sex slaves were mostly equals, but some were due to marry him when he became King, with the rest serving as concubines. There was no real difference in status between them despite that, though. Elsa was the sole exception. She was on the bottom rung of the pecking order, forced to obey all of Subaru's other slaves and refer to them as "mistress".
Beatrice watched Subaru and the happy new mother-to-be frolic excitedly. She was happy for them, but she couldn't shake the feeling of jealousy from within her. She was an artificial being. A great spirit. She couldn't bear children of her own. If things stayed as they were, she would never be able to be in Petra's place. She couldn't allow that. She turned on her heel and left. Soon, very soon, her time would come. The preparations were almost complete. She only needed to wait a few more weeks.
***
A few months ago, Beatrice had asked Subaru to become immortal. With so many incredible talents, it would be easy for them to give him the gift of immortality, so he could rule Lugunica, and all their bodies, for eternity. Beatrice reasoned that Subaru had to become immortal, or else…she would eventually be alone again. Subaru had considered the idea, and was open to it in the future, but he had refused. Subaru had reassured her, and told her that she wouldn't ever be alone again, and gave her the important duty to watch over all of his descendants, and serve any of his children with her mind and body the same way she served him. Beatrice hesitantly accepted, but while she could serve all of his descendants, she could never provide one of her own. Her days were so happy and blissful, but that thought truly did gnaw away at her.
She loved and trusted her master more than anyone, but even she would admit that he was somewhat of a hedonist. Someone who lived in the moment. When it came to discussions about the future, he could only offer reassuring words. She needed to take action. So she spoke to the person she loved most in the world apart from Subaru, her beloved Bubby. Puck was much more carefree than Beatrice, but when she approached Puck with her worries, Puck admitted that she too had the desperate desire to bear a child for their master.
And so, the two of them came up with a plan. As it so happened, Subaru had turned their creator, the Witch of Greed, Echidna, into another one of his personal fucktoys. If anyone had knowledge on how to impregnate a Great Spirit, it would be the one who created them, and the one who possessed more knowledge than any other. They both asked Subaru if they could accompany him to the Sanctuary so they could speak with her.
Puck and Emilia were always together, and due to the nature of the contract between them, Puck couldn't get too far away from the half-elf before the surroundings began to freeze over. Thus it had seemed like she would have to accompany them too. But Subaru had said it wasn't a problem, and forged a contract with Puck right there on the spot, overwriting the contract he had with Emilia. And thus, their master suddenly had two great spirits contracted with him. Contracting with two great spirits was utterly impossible, but it seemed like Subaru just willed it to happen. Truly, her master was the most amazing man in the world. As for Emilia, she was more than okay with Puck ending her contract with her.
"If you think about it, aren't all of us contracted to Master already?" She had said. "I mean, it's different from a spirit contract, but we're all his exclusive property, aren't we? Soooo, I think it's definitely okay if Puck officially becomes Master's spirit! We'll still be together all the time, so I'm reeeaally happy about it!"
And so, the trio had set off to the Sanctuary. Beatrice was directly connected to it through her connection with her mother, so it just took a simple teleportation spell. Normally, neither Beatrice nor Puck would be granted an audience with her spirit that still lingered within the tomb, but with Echidna being Subaru's adoring slave and answering to his every whim, she was more than happy to invite the two to a tea party.
Beatrice was so happy to reunite with her mother. She had cried into Echidna's arms. Puck's relationship with Echidna was quite a bit different, but they had their own reunion as well. As she had suspected, Echidna really was the key to finding a way for their master to impregnate them. Together, they had worked on a solution to this problem. As a disembodied spirit, Echidna was also capable of sympathising with their plight of not being able to have children, and she worked dutifully to set things up so their bodies could be…edited. Puck and Beatrice had visited the Sanctuary a few times by now. Beatrice enjoyed spending time with her long-lost mother, and every trip they took there furthered their goal of bearing Subaru's children. Beatrice and Puck would talk privately with Echidna, and Subaru would amuse himself by fucking the rest of the witches into a stupor. It would only take one more trip, and they would be ready.
"Prepare yourselves for the jump, I suppose."
That was where they found themselves now. In the Forbidden Library, with Beatrice preparing to send them to meet Echidna once again. As always, she was accompanied by Puck and Subaru. Her heart hammered in her chest. She could feel herself already starting to get wet from the anticipation. She was so excited. The time had finally come.
***
"Welcome back, my master."
The silky smooth voice of Echidna was the first thing that graced Subaru's ears following the teleportation. He opened his eyes to find himself in a vast, grassy expanse. As always, Echidna was sitting at her little table, sipping her tea. And also as always, the rest of the witches perked up at his presence, waving at him, or outright begging him to fuck them. Subaru ignored them, sitting down at the open chair opposite from Echidna.
"Beako and Puck couldn't hide their excitement. I guess that means today is the day?"
"Correct. As a fellow maiden in love, I've been working diligently to fulfil their greatest desire. I've even given up multiple opportunities to lay with you for the sake of my work, so you know I've been taking it seriously." Echidna sighed deeply. "It's been tough for me without a frequent dose of 'vitamin D', as you call it. I do hope you thoroughly reward me for my efforts once you've finished putting a baby in their bellies. But would you first indulge my curiosity on one matter?"
Subaru took a long sip from the tea in front of him. Like always, it was a sweet-flavoured helping of girlcum contributed to by all the witches, brewed with Echidna's tea to utter perfection. It suited Subaru's palate perfectly. He downed it all in one gulp, before gesturing for Echidna to continue.
"With your power, it would be beyond trivial to rewrite a Great Spirit's being to make pregnancy possible. You would need only speak the words and it would be done. And yet, you've chosen to let them toil and struggle for the sake of that goal. Why?"
"Because that struggle is itself beautiful, in a way. " Subaru answered. "I mean, you're right, I could have just used Jealous Dominion, and the thought did cross my mind, but seeing them working so hard together, it got me pretty invested. I wanted to wait and see what they came up with."
"So despite having a power that means you don't ever need to struggle, you still enjoy revelling in the struggles and failures of others?"
"Don't phrase it like I'm some kind of sadist! It's the same reason I didn't use Jealous Dominion to get Petra pregnant! I truly believe in all my girls. I might own them all, but seeing them work hard and grow in the process of achieving a goal makes me so proud of them! It's like, I dunno, I feel like a proud father."
Echidna chuckled softly. "Oh? Their father, are you? You certainly have an interesting relationship with your children. I certainly fear for the chastity of any future daughters you may have."
"Again, you just had to make it weird! It might be true that I have basically no limit when it comes to who I go after, and it might be true that my strike zone got more flexible over time, and it might be true that I always wanted a daughter who would admire me so much that she would want to marry me when she grew up, but that doesn't mean I'd-" Subaru paused for a moment as his brain caught up with his mouth. "Look, I don't know, okay? I've really never thought about it. But at this point I can still recognise that I've crossed pretty much every other line that there is, so…"
"You don't need to take my lighthearted banter so seriously, Master. Besides, I've long fantasised about giving birth to a daughter for you, moulding them to your liking, and then offering them up along with myself to serve as your cum dumpsters."
"You are the most terrible influence a daughter of mine could possibly have!" Subaru shouted. "Look, whatever. Speaking of having a kid, how would you manage that anyway? You've been helping Beatrice and Puck, but do you have a plan for you guys? You're all dead already."
"Surely you're not so unimaginative that you can't solve this problem…"
Subaru hesitated. "Well, my ability does have some limitations… I was thinking of a way to get you guys out of this tomb and into somewhere more convenient. A long while back, one of the other witches told me about a scheme you were cooking up where you would possess a body. Omega something?"
"Oh, that." Echidna laughed. "That plan was a holdover from a prior time. Since then, I've been observing you. I don't know if you've realised this, but the 'limitations' you're thinking about don't really apply to you anymore. Your ability has mutated with months of consistent usage, and it's become even more powerful."
This was news to Subaru. Jealous Dominion let him do almost anything he had wanted, so if there was some kind of evolution to his ability, he hadn't noticed. He supposed it was like how if you talk to somebody every day, you might not notice the subtle ways they change over time. Further thoughts on the subject were interrupted when he felt a hand reach into his pants and fish out his cock. The hand was replaced by a wet mouth shortly thereafter. Hmmm, it's a fairly small mouth. Typhon? The mouth started to lick and slurp at every inch of his cock, coating it in egregious amounts of saliva. Ah, nope. With this sloppy technique, that's definitely Daphne. He reached a hand down to lovingly run it through her hair. He still hadn't brought Satella here yet. Fucking all seven of the witches at once was definitely on his to-do list.
"Please try not to get distracted, Master." Echidna's voice jolted Subaru back to reality. "Under normal circumstances, the Omega Plan would have given us host bodies, but they would essentially be shells that hosted our souls. With how your power has evolved, you could rewrite reality easily to give all of us our real bodies back, and restore them to life. Your prior limitations, such as requiring the target to hear your voice no longer apply. Your power could go beyond life and death now."
He…could do something like that? He had long thought about the conditions for what it would take to bring the witches out of here and into the mansion. He had fantasised about having them all serve as his maids, and warm his bed at night. He could actually do it, just like that?
"Don't get me wrong, Master. It will require some preparation on my end. I've had no time to pursue it while I've been working on Beatrice and Puck. But…" A mischievous glint appeared in her eyes. "Please do come and visit me again. I'm as eager as you are to have all seven witches brought back to the world…and reunited under the banner of your glorious cock."
Along with the eager blowjob he was receiving from Daphne, the thought of him parading around the seven witches, all of them on their hands and knees, with collars around their necks, brought him to his limit. His cock erupted, painting Daphne's mouth with his cum. He heard her moan of contentment from underneath the table as her mouth and tongue frantically worked to milk Subaru's cock of any remaining fluid.
He caught Echidna peeking beneath the table, subtly rubbing her thighs together, a blush on her face and unable to completely hide the longing in her eyes. She cleared her throat and regained her composure. "Since you're now finished, I believe the time has come for you to leave." She made a shooing motion with her hand. "Sorry to force you out, but I need to add the finishing touches and complete the process. It will be nicer for everybody if it's a surprise for you. When you wake up, you'll get to meet the new Puck and Beatrice. I'm sure you'll be quite pleased with the results."
Subaru's world went dim and his consciousness faded momentarily. He slowly opened his eyes to see faint traces of magic dancing in the air in front of him, two shapes obscured within the shadows of Echidna's tomb, before suddenly there was a rip in space, and Subaru found himself back in the Forbidden Library, where they had started. Subaru scrunched his eyes as the sudden light hit him uncomfortably. He started rubbing his eyes to try and return them to normalcy.
"Um, s-so…Master? How do I look, I wonder?" A familiar voice called out to Subaru, but it felt somehow different. He opened his eyes, and as his eyes adjusted to the light, the blurry speaker before him gained a solid form.
The figure before him was unmistakable. The frilly pink dress, the striped leggings, and the long, blonde curls. It was of course none other than his favourite little loli fleshlight Beatrice, but…she wasn't a loli anymore. She stood much taller, and although her dress was far larger now, the furry collar of the dress was straining to contain an immense chest. Her once dainty legs were gone, now replaced by large, thick thighs. Her face was less round and soft, giving her a more mature appearance. Subaru stared at her, taking it all in.
Beatrice shifted nervously at his silence. "S-say something, I suppose…"
Giving a contemplative hum, Subaru brought a hand to his chin. "If you're asking me whether I like it or not, I obviously do. You were already beautiful before, but now if I compare you to any woman in the world, there's almost no comparison. No doubt about it, you're an elite-class ten out of ten beauty that few could hope to match."
A relieved smile came across Beatrice's face, but Subaru continued. "But you also have to consider what your own personal charm points were. A legal loli is a one-of-a-kind rare item. An SSR gacha pull. Petra, Meili and other lolis will eventually grow up, but you would forever stay the same. Are you throwing away your individualism just for the sake of pursuing a more traditional kind of beauty?"
"Well excuse Betty for wanting to experience something new!" She yelled. "Master, you jerk! I go through all this effort and that's what you say to me?!"
Subaru blinked. "Wait, are you actually mad?" This was new, one of his girls had never snapped at him before. "Um, sorry, Beako. That was rude of me. I know how hard you worked for this. Please don't get upset."
"As if a trifling matter like this could upset me, I suppose!" Beatrice crossed her arms and huffed in annoyance. "Betty can change her form however she likes now! A form such as this is far more appropriate for giving birth, I suppose."
Beatrice brought her hands to her chest, pulling her dress down to expose her cleavage. "And there are certain…features of this body that Betty couldn't make use of before." Beatrice leaned into Subaru, pushing her sizable chest against him. The volume of her voice dropping and her tone becoming deeper and more sultry. "Betty got so jealous watching other women rubbing their breasts all over you, I suppose." She leaned forward to seductively whisper in his ear. "Betty wanted to experience what it would be like to take Master's amazing cock between some breasts of her own…I suppose."
It took every ounce of Subaru's willpower to not drop his pants, tear off Beatrice's dress and start giving her the experience she wanted. But he noticed the absence of their third at the same time that they spoke up.
"I wanted to let Betty go first, but please don't forget to look at me before you take her, Master." They called.
Subaru whirled around. Stepping out from behind a bookcase was a brand new, transformed Puck.
"Oh, Bubby…" Beatrice gasped. "You're beautiful."
Subaru couldn't disagree. Puck had always been capable of changing her size, but her animal-like body structure had always remained. Things were now different. Puck's body had now adopted a more humanoid appearance. Her head was smaller, face flatter and distinctly feminine. Below her fluffy collar sat a pair of white, slightly furry breasts, complete with adorable pink nipples. Her waist was now slimmer in comparison to her body, and the size of her hips had expanded outwards. Adorning her lower body, just above her pussy, was a pink womb tattoo in the shape of a heart, glowing faintly. Her limbs were no longer short and stubby, and were now more proportional to the rest of her body. The size of her tail had also shrunken slightly and she stood a few inches shorter than Subaru, around Emilia's height. To put it in simple terms Subaru was familiar with from his old world, Puck had been anthropomorphized. It was an appearance not dissimilar to some of the Demi-Humans that lived in the world, such as Ricardo from Anastasia's camp.
"Yes!" Subaru called out. "Haha, this is unreal, Puck! What an amazing change! Whose idea was the womb tattoo?! That's just a classic, I can't believe we've never had them in the harem!"
"That was Mother's idea, I suppose. Both of us have one. We didn't understand it at first, but she said it would make you happy and would be proof that you owned us. When put in those terms, is it hard to understand why we agreed to it readily, I wonder?" Beatrice explained.
"Echidna definitely gets it! She's someone who just fundamentally understands how the game is played! Seriously, Puck, you look incredible! Very cute!"
A faint blush appeared on Puck's cheeks. Another new feature from Echidna, obviously, as Puck was incapable of visibly blushing before. "Thanks a lot, you two. Echidna and I spent quite a while discussing what form would be best for pleasing you and carrying your child. I'm glad our long discussions paid off." Puck turned to face Subaru and adopted a serious expression. "But first, I have to say something to you, Master. You should really be more careful with your words. What you said to Betty before wasn't very polite."
Beatrice waved her hands in panic. "Huh? N-no, Bubby, it's fine!"
"Because of our deep connection as your contracted spirits, your arousal came through loud and clear, so that was mainly what we were feeling." Puck continued. "But you should know that there's a time and place for a serious review. We both know you just meant it as a critique, but your delivery was quite tactless." Puck got a serious look in her eyes. "Your opinion is everything to us, Master. I don't think Betty could emotionally recover if you were actually displeased. The same goes for me."
I can't believe I'm getting lectured on social tact by my sex slave. Subaru thought to himself. Puck was right though, Subaru's old bad habit of blurting out whatever was on his mind had come out. "You're right. Sorry, Puck. Sorry, Beatrice. When I enslaved both of you and made you my bitches, I took on the responsibility of taking care of you. I made a vow long ago, after all." He thrust a finger up to the sky. "My name is Subaru Natsuki, and the lovely ladies of my harem must be the world's happiest!"
Puck nodded. "As long as you understand, Master. We're your property to do as you please with, but you're not the kind of person who would mistreat us." He turned to Beatrice. "We're lucky to be owned by such a caring guy, aren't we, Betty?"
"Master isn't just kind, he's also so handsome. There's no one like him in the world, I suppose." Beatrice rushed back to Subaru's side, grabbing an arm. "Well, Master Subaru, is Betty's voluptuous new body turning you on, I wonder?"
Puck moved to take Subaru's other arm. "Who will you take first, Master? Which of us gets to be the first one to experience the privilege of bearing your child, making use of our brand new wombs?"
"You two sure have a way with words." Subaru replied. "But you don't ever want to skip straight to the main event. Beako, you wanted those new tits of yours for a reason, didn't you? Now's the time to use them."
Beatrice nodded eagerly, quickly ripping her dress apart from the middle, exposing her huge breasts with a healthy bounce. It was as good a pair of breasts as any Subaru had ever seen. Beatrice's upper half had no clothes left, leaving her clad only in her striped tights. Like she said, she had a womb tattoo of her own. It was still partially covered by her tights, but was clearly visible. It had the same heart shape and pink colouration that Puck's did. Subaru moved to take off his own clothes, but Beatrice interrupted him.
"Don't bother, I suppose." She snapped her fingers, and Subaru's clothes were blown straight off his body, leaving him completely naked and revealing his obviously erect dick. It was a cool trick, but it wasn't Subaru's primary concern right now.
"Hey, my tracksuit!" He whirled around, to see if he could salvage anything from the remains. "It's…fine?" His clothes were completely intact, sitting in a pile right behind Subaru. He turned to face Beatrice, who looked smug.
"A new trick courtesy of Mother, I suppose. All that time spent removing clothes is such a waste. This is a much more efficient way of doing things. How do you like it, I wonder?"
"There's definitely an appeal to slowly stripping a girl, peeling away one layer at a time." Subaru replied. "But you're right, sometimes you just wanna get right to it. Thanks a lot, Beako. This'll help a lot when I'm fucking my girls all at once."
"I'm glad you're happy with it, I suppose. But Betty would prefer if you instead thanked her by covering her lewd new body in your seed, I suppose."
Subaru couldn't possibly deny an invitation like that. "In that case, let's move this straight to the bed." He scooped Beatrice up in a bridal carry. This was the easiest thing in the world with the old Beatrice, and Subaru feared he wouldn't be able to carry her so effortlessly, but to his surprise, even with a new, significantly larger body, Beatrice barely weighed any more than she had before. I guess spirits follow whatever rules they want to. He thought to himself.
The Forbidden Library had undergone slight remodelling back when Subaru had first awakened to his power, and there was now a large and luxurious bed inside. Beatrice was almost always in there, and it was important for her to be as comfortable as possible when Subaru was pounding her into the mattress.
Subaru sat down on the edge of the bed, placing Beatrice down with him. Her eyes were glued to his cock and she quickly slid off the edge to take her place on the floor, down on her knees. There was definitely one part of Beatrice that had weight now, and Subaru could feel them wrapping his dick softly on either side. Puck kneeled next to Beatrice on the floor, hoping to get a closer look.
An odd giggle passed through Beatrice's lips. "Finally, I suppose…" Subaru didn't really know what to make out of her exclamation.
"Betty's been real jealous about this one, Master." Puck chimed in. "Even though you enjoyed her old body so much, she's been wanting to do this for a long time."
Beatrice moved her hands to the sides of her breasts, slowly moving them up and down, humping Subaru's cock in-between them. It was hardly Subaru's first experience with being titty fucked, but Beatrice's size and the weight of her breasts made it one of his better experiences.
Beatrice's head dipped slightly lower, and she started licking and sucking Subaru's tip as it poked through the top of her cleavage. She picked up speed with her titjob and her sloppy mouth work was getting saliva everywhere. Subaru ran a hand through Beatrice's hair, but her gaze didn't move, hyper-focused as she was on her work.
"Here it comes, Beako. Make your master cum with your tits, the way you've always wanted."
True to his word, Subaru's cock erupted, spraying his seed up onto Beatrice's face, and the remainder falling all over the top side of her boobs, covering them in white streaks. Beatrice was dazed for a moment, taking it all in and enjoying the feeling of Subaru's cum slowly running down her body.
Puck didn't waste the opportunity, scooting over to Beatrice and running her tongue along Beatrice's face and breasts, gathering up all of her master's precious cum that she could. She then wrapped her arms around Beatrice and met her in a kiss, sharing the cum she had gathered with her fellow sibling spirit. The two of them moaned softly as their tongues clashed, and Subaru just enjoyed the show. He loved seeing his girls get along, and not many combos got along as well as Puck and Beatrice.
After having thoroughly cleaned out each other's mouths, the two finally broke their kiss, blushing happily. They turned their attention back to Subaru.
"That was awesome, Beako. I hope you enjoyed it too, because you'll be doing it a lot from now on." A wide smile fell across Beatrice's face as Subaru turned to Puck. "How about you, Puck? Eager to put those new tits of yours to work?"
Puck's tail swished happily at Subaru's idea, but she maintained her composure. "Maybe another time. I can change their size too, so there's a lot of room to experiment. But for now…" Her gaze flicked to Beatrice, who still seemed to be in somewhat of an ecstatic daze, a long dream of hers finally realised. "Do what you came here for, and fuck a baby into that slutty little spirit."
"I'm surprised you can keep your hands off me, Puck. Beako is lucky to have such a supportive sister." Subaru quipped.
"If you're happy with my support, kindly reward me by fucking me until I can't think straight when you're done with Betty."
"You don't need to worry about that, Puck. That was always the plan." Subaru ran a hand over Puck's head and scratched her ear gently, making her purr softly in content. Beatrice climbed onto the bed, blushing fiercely. She and Subaru had fucked countless times, but the gravity of this occasion wasn't lost on either of them. Subaru turned his attention to her, and pushed her down onto her back. He aggressively pulled Beatrice's tights off, and her panties with them, enjoying how they subtly stuck to her around the crotch area. Her womb tattoo was fully revealed, and Subaru ran a hand over it experimentally, which made Beatrice gasp. Subaru looked up at her quizzically.
"M-Mother said that, when our master, and only our master, touches that mark, it will send us a wave of pleasure, I suppose. It…definitely works."
"A whole new kind of foreplay was just unlocked!" Subaru realised. "Echidna really outdid herself with these. I might have to see if I can get one for everybody."
"That would be great, Master!" Puck called out. "It shouldn't be too hard to find a way for you to be able to apply them. I'm sure they would love being marked, too." Puck's thighs shuffled against each other. "I know Lia would be really happy with it. The thought of both of us being marked like that is…nice."
Subaru continued to trace a finger lazily across Beatrice's womb tattoo, making her moan softly.
"If you keep that up, Betty will definitely cum, I suppose!" Beatrice cried.
Subaru decided to experiment, pushing down harder on the tattoo with his thumb, dragging it across the surface. As the pressure he was putting on it increased, so did the volume of Beatrice's moans. It only took a matter of seconds for Beatrice to be brought to an orgasm, leaving her panting softly. It seemed this tattoo was surprisingly effective.
"We're not done yet, Beako." Subaru whispered.
"Then take me, Subaru. Take all of me! Make me a mother, I suppose!"
Subaru lined himself up, and thrust into Beatrice without hesitation. He could immediately feel the difference between Beatrice's old and new body. She was incredibly tight in her old form, and no matter how hard Subaru fucked her, that had never changed. Beatrice wasn't as tight anymore, but her warm cunt massaged his cock perfectly, as though it were perfectly moulded to fit him. Given Echidna's many experiences with it, that very well may have been the case. Subaru pulled himself right against Beatrice, feeling her boobs squishing against his muscular body. He didn't pound Beatrice as hard as he usually did. He wanted to make this moment special for her. Subaru could vaguely hear soft gasps from Puck, who was watching the two of them, enraptured, touching herself gently. Subaru and Beatrice fucked tenderly for several minutes, Subaru looking deep into Beatrice's eyes, marvelling in the beauty of her butterfly-shaped pupils and how they occasionally scrunched shut in pleasure, all for him. Beatrice's quiet gasps and unmistakably womanly moans helping him along the way to his climax.
"It's time, Beako. I'm going to cum inside you, just like I have so many times before. But this time I'm making you a mother. I promise."
Tears began to spill down Beatrice's cheeks, but the way her eyes shined and her bright smile made it clear what she was feeling. "I've been waiting so long." She sobbed softly. "For four hundred years, I was all alone, waiting for That Person." She wrapped Subaru up in a tight hug even as he continued to thrust himself in and out of her, wetting his shoulder with her tears. "But I found him.. Betty's going to have a real family with the one she loves most! Betty doesn't have to be alone ever again!"
Beatrice pulled away from the hug to once again look deeply into Subaru's eyes.
"I'm ready, Master. I'm ready, I suppose! This body Mother gave me can control my fertility rate. When you cum inside me, when you fill my body with your love, I'll definitely get pregnant, I suppose!"
Beatrice's voice cracked and gave way as she began to reach her orgasm, her whole body beginning to tremble.
"CUM INSIDE ME, SUBARU!" She wailed.
Subaru's pace increased more and more, and now feeling Beatrice's walls tightening around his cock, he couldn't hold back the tide anymore, his balls churning, spraying Beatrice's new womb with a healthy supply of his semen.
Beatrice continued to moan as Subaru emptied himself into her, until finally she became breathless and went limp. She and Subaru panted softly from the exertion. Subaru slowly slid himself out of her, rolling to her side and giving her a loving cuddle. Beatrice smiled and rubbed her stomach gently.
"Subaru's baby. Master's baby. I can't wait to meet you, I suppose."
Subaru couldn't wait to see what Beatrice would like while pregnant, her belly bloated, and her huge breasts filled with milk. The mental image was already starting to make him hard again, which was good, as there was still work to be done.
"I'm so happy for you, Betty." Puck spoke up. She looked genuinely emotional.
Beatrice smiled. "Thank you, Bubby. Now it's your turn to have your dream fulfilled." She made room on the bed and moved to a chair on the side, wanting to see Puck's impregnation closely for herself.
Puck took her place on the bed, slow and methodical in her movements. "How…do you want to take me, Master?" She asked, her eyes unable to quite meet Subaru's.
Subaru was quite surprised at Puck's current state. The spirit had always been exceptionally playful and eager. She threw herself into sex with Subaru readily, and that hadn't changed since the day Subaru first fucked her. Seeing a genuinely blushing and nervous Puck was completely new for him, and it made his heart race.
"What's the matter, Puck?" Subaru asked. "Didn't you ask me just before to 'fuck you until you couldn't think straight'? You're not getting cold feet, are you?"
"No, never!" Puck gasped. She paused, trying to find the right words. "...I've lived a long time, but the wait to make this possible, working together with Echidna and Betty, it was only about a year, but it felt longer than my whole life up to that point. I've never wanted anything so badly in my entire existence." She finally met Subaru's gaze, trying to bring back her usual smile. "I just…can't believe that it's finally happening, that's all. It almost doesn't feel real. I'm going to become a mother."
"You mean you weren't a mother already?" Subaru pointed out. "Emilia will be so distraught to hear that."
"You know this is completely different!" Puck pouted. "Geez, talking about it is just making me even more nervous, hurry up and do it already!"
Subaru closed the distance between them. "Puck…" He whispered, before capturing her lips in a kiss. Immediately the difference was clear. Subaru didn't exactly kiss Puck a lot previously, her ass and pussy were still perfect, but her cat-like maw had been awkward and uncomfortable to kiss. Her current form felt a lot more natural. Their lips were able to meet without issue, and Subaru easily slipped his tongue into Puck's mouth. Her tongue was a lot smoother now, he noticed. They made out passionately. Puck had never said anything, but he wouldn't be surprised if not being able to kiss Subaru often weighed on her. It was like she was getting all those feelings out through their kiss now. If this was how different her mouth was, how about everything else? Subaru planned to thoroughly test every part of her new body over the next couple of weeks.
Subaru broke the kiss, and his head ducked lower, to her brand new pair of tits. He took a nipple into his mouth, sucking on it lightly and flicking it with his tongue, making Puck squirm and gasp. Because of Puck's fur, it felt a little odd, but the fur on her breasts was extremely short, and silky smooth. He swapped to her other breast, giving it the same care and attention he gave the first one. Whatever breast he wasn't sucking, his other hand was groping and caressing gently, thumb playing with the nipple.
"W-wow…" Puck rasped. "Boobs are incredible… I've been missing out."
Subaru also reminded Puck of her other new feature, dropping a hand down to her womb tattoo and stroking it gently, making Puck shiver and mewl with pleasure. Subaru stopped for a moment, holding himself up above Puck in a pushup position. He took a moment to get a closer look at the new Puck. She was vulnerable and blushing, her eyes filled with adoration for her master. He couldn't deny how much he liked what he saw.
It was crazy for Subaru to think that this Puck he saw before him, this eager little kitty, in desperate heat, looking to be bred, was a complete accident. He hadn't had any plans to have sex with Puck on that day he first took her virginity and made her his bitch. It was just a mistake brought about from his novice use of Jealous Dominion. And just look at her now. She had turned out so well. Even though it was an accident, Puck was a conquest Subaru was truly proud of. A world-destroying apocalyptic beast, turned into…this. Sure, he wasn't the last calamity to fall before Subaru, but he was the first. And you never forget your first. Subaru's cock was painfully hard, and he didn't want to waste any more time.
"I'm going to give you that baby now, Puck. And I'm not going to be gentle." Following those words, Subaru immediately slammed himself into Puck as far as he could go, at the same time pressing two fingers down hard on her womb tattoo. The effect on Puck was instantaneous, and she immediately came around Subaru's cock, clenching down tightly around him with a girlish scream. Subaru slammed himself into her again and again, as Puck wrapped her arms tightly around him, clinging to him for dear life, with Subaru's arms coming behind her to pull her into him.
The Forbidden Library was a cacophony of lewdness. Puck's moans and Subaru's grunts echoing off the walls along with the wet sounds of their sexes slapping together. Beatrice also contributed with her own shlicking sounds from where she was fingering herself. Subaru was already riding the high of finally impregnating Beatrice, and with Puck's impregnation imminent, he just had to say something.
"Hey, Puck. Do you know what I did to you?" He asked her. Puck wasn't expecting the question, and amidst their fucking could only throw out a curious hum.
"I used my authority to control your mind and make you my bitch. You had no choice but to submit to me."
"Yesss! I knoooow!" Puck managed to moan.
Subaru couldn't see Puck's expression from where she clinged to him, but he could hear her voice loud and clear in his ear as she shouted her adoration, she continued to orgasm around his cock as Subaru continued.
"You used to be such a proud spirit. All you cared about was keeping Emilia safe. And let's not forget that you used to be a boy. Just look at you now. Look what you did to yourself, all for my sake."
"It's all for you, Master! Everything is for you! Seeing you, smelling your scent, hearing your voice, tasting you, feeling you inside me! You make my heart go so crazy I can hardly stand it!"
The rush of masculine pride he felt as Puck continued to praise him, combined with the knowledge that he was about to impregnate yet another woman, it brought things to a new level for Subaru. He had coaxed several orgasms out of Puck by this point. His thrusts picked up in intensity as he felt himself approaching his own limit.
"Thank you so much, Master!" Puck continued to shout. "Thank you for twisting my mind and making me yours! I've been so happy every single day!"
Subaru came, firing everything he had inside of Puck. She noticed that her master had finally cum inside of her immediately, as she let out her loudest scream yet, her voice echoing off the walls of the Forbidden Library.
"I love you! I love you, Subaru! I love you so much!"
Subaru tried to regain his breath as he came down from his climax, as Puck continued to whisper her love to Subaru. Cumming inside women he owned was nothing new, to say the least, but it seemed like his body subconsciously made sure to give them an extra large load of cum when he was trying to impregnate them, to really seal the deal. Or maybe it was just from his own heightened arousal.
"I'm happy I can give Emilia a sibling…" Puck cooed. "I wonder what you'll look like…"
Subaru also couldn't deny his curiosity at what exactly a child born from him and Puck would look like. Maybe a human with cat features, kind of like Ferris? Well, he would have to wait and see. He slid himself out of Puck, making her whine in disappointment, and took a look to inspect his handiwork. Puck's fur was matted and wet with their combined sweat, and with the amount of cum leaking from her thoroughly fucked cunt, he knew there was no way Puck wouldn't be pregnant even without her and Beatrice being able to control the odds.
Subaru rolled onto his back, pulling Puck against his side. She snuggled into him, nuzzling her face in his armpit. Beatrice joined him on the other side, her breasts pressing against the other side of his chest. Subaru thoroughly enjoyed being in the middle of this spirit sandwich. The trio lay there for a while, simply basking in the afterglow of their lovemaking. But with two freshly impregnated beauties that he owned in every single way clinging to him so lovingly, he couldn't help but get hard again.
"Ready again already, Master?" Puck asked. Her facial expression showed that she was hardly surprised. "Geez, you're utterly insatiable. It's going to be hard for Betty and I to tire you out on our own."
"It's a good thing that our master is ready to perform again, I suppose." Beatrice said from his other side. "I know I said that we chose to have one hundred percent fertility, but…" Beatrice smirked at Subaru. "It is best to be thorough with these things, I suppose."
Subaru knew that he wasn't going to be leaving the Forbidden Library any time soon.
