Munetsuchi

One thrust was indeed all it took for Yume to experience sheer bliss. Of course, Mugen didn't seem like the type to stop at just one, nor did she really wish for him to be. In light of that single flourish she found herself looking forward to everything that was to come next. Miyuki would be having the force of this particular interaction forced upon him, but Yume wasn't trying to be spiteful anymore. She'd all but surrendered herself to a purely blissful experience. This experience came with a bit of leverage gained by a leash-like extension to the collar around her neck. And beyond that there was another firm slap to her bottom which caused her nether to tighten around him. He kept her balanced and continued to plunge into her repeated knocking her about while holding her body in place. Her moans filled this room her wet tongue hung from her mouth and the pulsing pupils in her eyes became hearts in shape. She seemed to be enjoying this rather rough treatment, and she currently couldn't even form the words to express it. Ah well, she didn't need to, the continued reaching of climax by her body and the sounds she managed to make might convey it enough, as her own brain overheated and she was left to dangle on the rope of her own pleasure.

Anais on the other hand was finding out her mentor's limits. That is to say, she was quite enjoying his current lack of composure. Perhaps, if she managed to think about it more, that is why she found herself so easily falling into ambiguously teasing the man and testing her newer skills and abilities on his person. Whatever the case, he had at least begun thrusting into her mouth which served the purpose of making sure that all that he offered found its home within her person. She wasn't having any trouble metabolising all the mana he offered her, and hadn't even really stopped to think about any potential problems it might pose. She met those upward strokes from him with her own mouth seeming pleased to be part of such an exchange. Her own relaxation in her body had her, at least not immediately trying anything different. No... she'd be content for a moment or two while she caught her breath, this was fine, eventually she'd need to back away, and free her jaw lest it lock into place... still her arms were far from tired so it wasn't as if stimulation would stop at all.

At long last, Mugen felt what he'd been waiting for. The seal placed on Yume had finally been pushed to its most solid point. The moment her eyes took the shape of hearts, Mugen's mark rooted itself even deeper into her very soul. He'd exist in her subconscious, appearing in dreams even when he had no desire to do so. One could possibly say she'd been 'broken', and that would undoubtedly be true in an old magical sense. She certainly wouldn't be much of a target for anyone else ever again, unless they were comparable to Mugen himself as a match. Knowing the likelihood of that ever happening, Mugen happily plunged into the depths of Yume's being, constantly pulling the leash around her neck and subjecting the room to one spatial reverberation after another. He'd reach a state of calm... eventually. Alas, it would have nothing to do with Yume's desire, and everything to do with deciding he'd had enough fun. Besides, she did have to start learning at some point ─ though for now, he'd only continue pumping excess and purposeless mana into her body. And so, the time would pass. . .

The same could be said of two others, it seemed. Between Ailen and his apprentice, neither showed any signs of retreat or reconsideration for their current actions. As bodies began to take over in a more natural manner, their fates were sealed to a more long-lasting endeavor than perhaps anyone anticipated. Ailen, for one, couldn't have imagined things dragging on for as long as they had already. Ah, but what would he do? Well... he'd let things carry on as they were, also falling into the flow of time until. . .

Mugen had all but broken this this lass's physical form. Well perhaps that was the wrong way to state it... instead he dominated all forms of her person; mind, body and soul. She had been aggressively treated this day and enjoyed it. Those pupils of hers pulsing as hearts when the man rammed himself in and out of her body at what had to be maximum force. Whatever pleasure he got from treating her this way, she also enjoyed for him. Mentally, if she had been capable of extra thoughts, she'd decided this was perfect and as time passed it only became more perfect. She'd made the decision to give herself to this man as completely as possible and she enjoyed it. All that purposeless mana deposited into her form over time seemed to just be coursing around her body.

But all couldn't remain the same. Eventually the girl would be found in a different position, her back against his bed her legs around his shoulders and being pummeled from a more direct angle. From this position she got to stare into his face and confront that thing of her fantasies those glaring eyes. How she'd ever thought anything else would have done, she didn't know. But it was clear to her now that this was it. The look, the aggression, the feeling. She was sure her body had nothing but reactions left to give. She was still moaning happily that tongue of hers still hanging out of her mouth, her vision still full of heart-shaped pupils, but she was far from disliking anything about this situation. Actually as he reached this level of depth inside her person, those hearts were beating in time with the feeling of her loins before they pulsed to a stop, signaling the start of her next flourish.

Some three hours after successfully unlocking the more deviant side of Yume, Mugen's 'fun' was winding down. Of course, winding down included further pummeling of the girl's recently-adjusted body using a new position, but the method was of little importance... or perhaps it was actually of great importance, depending on the perspective. Mugen would believe the latter, as he'd been observing the already small amount of resistance Yume had fading by the minute. At this point, he believed anything could be done without any naysaying from the lass. Whether that was true or false, he was currently enjoying much freedom of movement. With Yume's legs so out of his way, the demon's hips were free to piston wildly as he continued enabling those world-shaking reverberations.

It had been some time since Mugen last deposited his mana into this new apprentice. That, however, was a restraint he showed with purpose. The girl needed to learn some things eventually, so he'd been building up quite the reserve of knowledge to penetrate down to her soul. "As fun as this has been, I think it's time for your lesson. Ready to learn, Yu-pyon~?♥" he asked. A few moments and a few plunges later, he'd subject Yume to the mightiest expulsion yet. Her insides would be filled so wholly and so quickly, much would be expelled as an almost immediate consequence. No matter; Mugen had focused more than enough information to deliver the full breadth of necessary knowledge regardless. Yume would be infused with all the information needed to be considered a theoretical master of astrology and divination. As a single teaching session, it was an excessive amount he delivered unto her. Alas, one tended to discover rather quickly how excessive demons were. . .

Yume had been actively engaged by Mugen for hours. She currently had no concept of the amount of time that had passed, and as far as she was concerned she didn't need one. No, she'd been far too busy enjoying herself to care much one way or another about the amoutn of time she'd spend in this world engaged in sexual activity. Ah, but sex didn't have to be just sex in this world, and given that even though they'd both apparently been having fun she still had to get to her lessons. Oh she was supposed to be learning something and was asked if she was ready. Well... "Hai, Mugen-sama♥!~" the girl mentioned. Granted she didn't know any real need to do anything else, she would at least gain whatever knowledge he had to offer.

Luckily for her however, this wouldn't be an immediate thing. No, a few more knocks around her person would send the girl over the edge and while that was happening Mugen would also be expelling mana. In so doing he delivered a great deal of information directly to the girl's brain about divination and astrology? Ah, it was spreading through her body and out of it at the same time. It was binding to her soul, and... given her own nature she allowed it. Her understanding of divination seemed to be infused to various aspects of her new magical world understandings. Even her understanding of how to feel mana seemed to be affected. Actually, it was more purposeful than that... it seemed like those two things were innately connected. She came to feel more even as she was being spilled in. She understood so much now, she could feel it. Not just physically, but spiritually. It was like she could understand what was being felt in the depths of someone's soul. Ah... that was a strange thing to realize as she started with herself then the man connected to her and then the power reached out further still. And when it did it came into contact with something she didn't like and she immediately pulled back from it. "Aaaahhh♥!~ That's a lot... it's so much!~ Ah, but I really love it though don't I?~" she questioned. As those hearts still pulsed in her eyes, though she seemed to be slowing down just a bit. When she had more time to think about it, she'd decide that much like her friend she enjoyed learning this way... it was such a good use of her time.

For some reason, Mugen found few things more satisfying than expelling more liquid mana than his partner's body could sustain. Perhaps it was the nature of Destroyers to enjoy feeling the sensation of overloading something, even when not literally destroying it. That seemed sensible. Either way, he was obviously content to enjoy letting every last morsel of his essence flow into Yume's body. Sadly though, there was no way to actually do such a thing; damn pouring mechanics had to exist even in a magical world. He'd have to do something about that soon. First, he had to bask in the moment, just as Yume herself seemed to be doing while processing new knowledge and... all of that fluid. As she did so, she presented the demon with a question. It was a lot, but she loved it? Making the assumption was easy, but that question also set Mugen up perfectly. "It looks like you do, but it's not like anyone else could be sure? I think there's only one way to be certain~♥"

With that said, Mugen decided to enact his plan. He'd first be found extricating himself from Yume's loins, taking a standing position on the open floor. That seal around the girl's neck would see use once again as he tugged on the ethereal leash connected to it. He was still dripping mana and very much covered in a mixture of their fluids. Since Yume claimed to 'love' it so much, he thought to give her the satisfaction of... well, the remainder, and whatever residual knowledge was left in that last little stream. "The only one who can say how much you love anything, is you. So... you tell me, and I'll try committing it to memory, Yu-pyon~♥"

Perhaps, today was the day of plentiful and strange developments. Her almost flirty question would be answered, not just by words but by actions. She was starting to really appreciate that quality in Mugen, even as her body was filled well beyond its burst point she seemed to be quite pleased by the sensation. She truly did think it was possible to love this sort of completely excessive approach. What was more, she was offered the ability to truly figure it out. That tattoo around her neck seemed to be used once more after he extricated himself from her loins and he'd take to the standing position properly. She was left the ability to move on her own and took the tug against her leash as gentle encouragement to take her place before him, which she did almost giddily.

He claimed that only she could decide for herself if it was something she loved. But according to Mugen, he'd try and commit it to memory for her. He once again used that pet name of hers, she'd come to enjoy so very much and she'd subsequently find herself accepting the remainder of his expulsion and their mixed fluids with her mouth. Her overly wet tongue would easily caress his manhood after that first expulsion and those heart shaped pupils in her eyes seemed to pulse as she tasted the sweet citrus of herself along with the spiciness of Mugen. She went about cleaning his tool with her own mouth but between lavished tongue strokes she did have something to say. "It really is something I love, and it's quite tasty, Mugen-sama♥!~" the girl chimed as she finished what she'd aimed to do. Just the same whatever residuals she got from accepting the rest of her mana this way, seemed to help her thoughts crystalize in her head. How interesting it was to process mana in this way.

With gentle coaxing of a physical nature, Yume took her place by his groin. She'd continue their flirty engagement by seeking confirmation, lapping at his cock in a way that didn't dry it at all ─ not with that wet tongue she used. Nevertheless, Yume was managing to take care of all residue in a seemingly thorough fashion. Ah yes, Mugen knew exactly how satisfying this relationship would be for him. The same could apparently be said of Yume as well, who went on to confirm her elation. "Ii shoujo da ne~♥" he harped. With that, regrettably, he figured their first session had come to an end. He didn't want to actually fry the mind and spirit of his apprentice, after all.

"As first times go, this has been a bit short... but you were just a human a few hours ago. I suppose I should consider it a victory that you could survive even that much," Mugen mused. Whenever Yume finished lavishing his shaft, he'd be magically redressing himself and commenting on her state of being... or rather, giving fair warning. "The inmon I used this time worked out quite well. It won't be going anywhere, though. The seal, the extras, the eyes ─ they'll all appear as necessary, and I doubt they'll go away until you're done processing. Frankly, I'm not sure which is stronger between yours and Miwa's. Now... we should be figuring out what to do with the extra weight sitting outside my bedroom. Are you dressing, or do you want the real one to watch my offering drip out of you too?"

Yume was rather committed as a pet. Well, maybe that wasn't exactly the truth, she was pretty committed to being Mugen's pet currently and had nothing but pleasantries and forward thinking to offer her new life. Actually, his commentary after her more flirty words left the girl with a gentle blush along her face. Strange, she didn't know she'd find such words appreciable but she truly did...

Moving on from this, having finished her work of cleaning up the demon's groin it would appear that this particular session and its accompanying lessons were over. This was almost confirmed by the words. He spoke of such a session being quite short, but claimed that this was fine as she had been human at the start of this endeavor. She imagined without the ability to become a different species, it might have been quite difficult to continue the way she had been. "Hai hai, I assume it could have been worse for me so I'll take it in stride..." she mused. Ah, but there was more to be discussed. Beyond this point, the seals that had been placed on her body were called inmon and wouldn't truly be leaving her. According to Mugen they'd taken quite well and would appear as needed. This was also fine, though he wasn't sure if hers or Miwa's was stronger? Ah, that was in her early information the goddess of this land, so his wife. It was an odd thing for her to realize she'd just been added to a polycule but she also didn't worry about that too much either. "All of that is fine, I understand..." she said of the marks still vibrating gently on her body. As for if she'd dress again while they did something about the dead weight outside she gave it a bit of consideration. "I think I'll get dressed, mostly because he'd like seeing it and I don't want to make him happy..." she said. Maybe she was still a bit spiteful? Or maybe she just had some understanding that she didn't before? She wasn't entirely sure but she'd probably figure it out sooner or later.

Given this, she went on to dress herself. That dress reappearing across her skin, though the markings on her body showed both through and around the small ornate dress. She also picked up that hat of hers, attaching it to her head and in so doing it seemed to take a form more suited to her 'alien' appearance, becoming a strange glow to her previously created halo and adding a host of information to be processed to her brain, but she'd used her left over energy for that. "Alright, I'm ready... Mugen-sama!~" she mused as her clothing begant he process of eating away at her current body, though it seemed to be a rather slow process, leaving her with the more thickened version of her form.

Whilst in the process of dressing himself, Mugen awaited several of the girl's reactions. First and foremost was the follow-up to an unusual compliment, which had the girl's face flushed in an obviously accepting manner. Second was the idea that all of their fun could have been something terrible for her if approached in excess. Mugen was sure she could handle anything at her current level of ability, but that was only physical. A mind, a truly broken one, could never be fully repaired; that was what he intended to avoid. Ah, but even then... a certain kind of mind-breaking was something to appreciate, and something Mugen himself had been aiming for. "Good. We don't want you too broken~" he declared.

As for the third point, Yume had to choose whether she'd dress, or avoid doing so entirely. She chose the former with the primary reason being her refusal to satisfy the boy she'd come to this world with. To that, Mugen quirked a brow and tilted his head. "Is that so? Well, that's a shame. You'll do exactly that eventually... even if it's not 'you' doing it," he commented as if possessing a secret about the lad. Moving on, Yume being dressed was reason enough for him to abandon the topic entirely. There was no point being in a bedroom and wearing clothes, after all. Whatever the case, she added the hat from earlier, giving it a new form to go along with her existing ensemble. Mugen took a moment to return his room to its former state, which inadvertently banished Miyuki before he stepped out. Along the way, there was more information to share with Yume. "You'll want to consider something, though. The real brat doesn't have memories from here; he's been in a vegetative state since you made that part of his consciousness move between realms."
