Kaguya was using her brain properly and that was an exciting prospect to the lass. Actually, this whole learning thing wouldn't be half bad, it even came with the physical type of interruption someone like her enjoyed so that she could concentrate better. Speaking of concentrating there was the matter of a positional change and apparently a very different interpretation of the more human form of sexual activity. She'd had her snack, given the way mana worked as energy that made sense. He was grinning at her in quite the disturbing manner but somehow it was only more attractive by the moment. And now she was going to be stretched until she broke.

She couldn't even think about the implications of that. It sounded so violent but also not like something she should avoid. She wasn't known for thinking very long about things, she'd willingly started this little journey, she had no issue taking her time stepping into it. Ah, but there was almost a noise wasn't there. The lad who'd been tied up watching this entire time, the one she'd been spitefully forcing to witness the 'slutty' behavior he believed her capable of was distraught. Why? Beyond that she was told not to worry about her breaking she'd love it more than anything else. Her mouth opened and that silent o happened again as she took his meaning. But a single whispered sentence came to her about saying goodbye to Shirogane Miyuki as she wouldn't be the same person in a few minutes. That new nickname of hers was included and it caused her face to redden slightly. And now she turned and looked down at the lad on the floor. In the moment she took him in she smiled and hers, was just as disturbing as the one that had been presented by Mugen, but maybe worse as she had a certain level of menace and still the spite. "Sayonara, Shirogane." she said just those two words, knowing even without anything extra that she had no real intention of allowing herself to sink into whatever filth this lad had left to taint her with. She'd made a choice, and severance was being served in two simple words.

Two words were offered as Kaguya turned toward the sniveling boy. Sayonara, she said. Mugen thought her choice was interesting. Among the words she could have used, she chose one that was the most... final. Two males were in this room, and both took special note of that particular decision. Miyuki sat wide-eyed and distressed, while Mugen stood wide-grinned and exhilarated. "Kuhuhuhu~!" the demon laughed. This day could hardly get any better.

Ah, but it could get a bit better with some physical relief. The darkness that had been creeping up Kaguya's form took her legs by force, lifting them both straight into the air. She wouldn't be flipped upside-down as a result, however. No, as Mugen pressed himself against her back, Kaguya's legs alone would be moved. The remainder of Mugen's clothes faded away to produce a connection of flesh he'd been waiting to experience for some time, his chest against the girl's back. "Now for the stretch~" he said while both arms hooked around the lass's elevated thighs. In that moment, she'd be able to see the demon's rod jutting out in front of her. It seemed he was a bit preoccupied, but that, too, was part of the plan. He did say she had to want it; she also had to choose it. "I think it's your turn now. You've ditched the deadweight; time to give yourself to darkness. Make sure you mean it."

Kaguya offered her goodbyes to her former boyfriend. She was sure she was done, even without any real discussion of it. If she was going to be a different person, she'd fully embrace it, as freely as she wished. Here and now, she planned to start her life with a new connection. The laugh of Mugen was something she was starting to enjoy quite a bit, regardless of the supposed distress she'd caused Miyuki. He'd caused her just as much, it was only fair. And now... she do something he'd assumed he could manipulate out of her.

Her legs were suddenly being drawn up by shadows. Of course, she was only human but she wasn't inflexible. Though it held a little bit of a stinging sensation it was far from uncomfortable. Soon enough there was warm muscled flesh pressed against her back and arms hooked under her legs. Ooh? That was quite nice to feel and as she looked down her body with all of his clothing faded she could see the object of her newfound desires. He was speaking once more, it was time for the stretch, apparently that applied to both of them in some ways. Apparently, this was her turn. She had to choose it, to want it. Well... she definitely wanted it... and she'd definitely choose it. Dainty hands made their way down her body to create the alignment. She was taking slow and steady breaths. She was rationalizing that she wanted it. Knowing feeling in her soul it would work even if it was a tight squeeze. She'd choose Mugen and his darkness in this new world before anything else. She'd manuever that rod until it made contact with her undercarriage. it would slip around her folds until the hole into her depths was found. It'd be aligned specially her own machinations making sure it stayed where she wanted it to be. "Okaerinasai, Mugen-sama!♥~" she mused. Her word choices would remain pointed. A final ending a welcome home, for the person in charge of the path she chose. If she was to hold his knowledge, he could make himself at home in her. Yes... that sounded like the right decision. Besides the magical aspects, this was all pretty hot, now that she was thinking about it, sex should always be this entertaining, she decided.

Once more, Kaguya's hands were making contact with his girth. Mugen found himself enjoying her touch, actually. Her touch was not as experienced as Miwa, but it was not wholly inexperienced either. At the very least, there was a certain knowledge of functionality applied with a dash of innocence to flavor the experience. Beyond the special quirkiness this one had to her methods, there was purpose. She steeled herself to wedge him between her folds. Once Mugen felt the kiss of her lower lips, he also heard an interestingly wholesome welcome. Home, she called it. How very blunt.

How would Mugen respond to that very direct welcome? Well, he'd respond as he always intended, albeit with fitting verbalization. "Tadaima, Kuraihime-chan~♥" he replied. Just then, it was time for their joining. Damned be the world and its refusal to accept his kind mating with mortals. Mugen thrusted his hips with force, aiming to squeeze his way between the human's folds against the will of fate itself. Frankly, he enjoyed this difference. Miwa had been more easily capable of receiving him, but there was always something special about having to work at a task. He felt a mighty squeeze while working tirelessly against a metaphysical barrier trying its damnedest to prevent further penetration. Though Mugen found most things quite effortless, he was grunting ─ even growling during that long, difficult, yet strangely satisfying entry. Thinking about it, Mugen decided he liked this part of the show better. He could feel the despair of Miyuki watching his former partner be taken in slow motion. He could feel karma taking its toll, manifesting in the atmosphere as his own power... which, bit by bit, was making its way into Kaguya.

One door closed and another one opened. Ah, how very interesting it was to be held like this and feel the start of a push well into her depths. This girl could almost laugh at herself for thinking she wasn't a virgin when men like this existed in any world. Strangely, despite the immense amount of debauchery that was about to take place or rather that was starting, the beginning was wholesome words of welcome and acceptance. He was home, at least, he would be when the world stopped arguing about it.

He was pushing into her core, and she was accepting. At every movement she was remembering to accept. She'd thought the first time she'd had sex was rough but this was... a special brand of problematic. It was so much pressure, it truly felt like she was stretching beyond the boundaries that her body would allow. She couldn't explain the sensation, but it was way more intense than any other sexual experience she could have had. Even so, she wasn't displeased. She was mentally anguishing practically squealing... and gently begging as the penetration continued. "Come on, come on... come on..." so soft were those words but they were quite close to being a demand. She wanted, this... she needed this. She didn't care if the world didn't want it, she did, so why did it matter! That despairing boy had earned this loss, she wanted to win, she deserved to win. She'd take her win! Yes, that was the type of life she wanted. She'd take from Mugen, she'd accept the darkness as it entered her body and it'd comply with her whims... this was what she wanted. And it would start with her body, she'd have it change to physically accept she'd use any method she needed to conscious or otherwise for the sake of this experience.

Mugen anticipated difficulty lodging himself into the girl, but even he hadn't foreseen this. During all that buildup before penetration, he expected a brief struggle and a sudden break beyond the world's resistance. Instead, what he found was a painstakingly slow insertion that had him feeling every fiber of Kaguya's womanhood contorting around him. This was better. The girl seemed to be finding pleasantries of her own, going so far as to urge on penetration with her words. One person in this room wanted nothing more than for a rejection to occur, even for things to reverse. Instead, what the human male got to see was even more of Mugen's girth forcing its way in.

"Come on, come on? Kuhu! That isn't going to work," said Mugen. The shadows around Kaguya's body were on the move as well, accumulating around his rod and flooding Kaguya's entrance even beyond the point he'd reached thus far. If what she wanted was to accept this entry, she had to do just a bit more than want it. "Humans really get into the physical part here, right? Why don't you... use that? I left you your hands, and... well, everything else~' Mugen said. Perhaps there was more than a single meaning to the statement. He knew of physical stimuli as humans enjoyed them, but beyond that, he knew there was a surefire way to reject the world as it refused mating with a demon. Becoming a demon oneself using mana already consumed, would undoubtedly cause the world to fail. Two demons couldn't be stopped at all. Of course, Mugen figured the lass was already well on her way to that discovery. . .

Kaguya was experiencing something that was great but just shy of amazing. The lack of her actually descending further down on his cock was distressing in away, she'd been quietly willing it to happen but apparently this wouldn't be enough. Mugen actually spoke in a surprisingly straight-forward way about the whole of it. Ah, he claimed the physicality of humans was to be exploited in the meantime. He pointed out that he'd left her the use of her body for the most part. Her brows furrowed rather gently at the notion but she smiled just the same. "That's... uh, surprisingly direct coming from you, Mugen-sama!~" she mused just lightly. She was still human and the world didn't enjoy this union. As such she'd have to use her body to fix that problem. The easiest fix in this particular case, would be to become not human. Miyuki had mentioned earlier that this was the video game world associated with the disappearances. She'd not gotten around to playing, but she understood the base of that sort of thing.

"Alright then," a different sort of acceptance took place. She began to burn up the energy almost subconsciously within her own body. Why, to convert herself from a human who couldn't accept this man into something that could. Maybe it wouldn't be enough but she might as well enjoy it. As the pressure increased in her loins she shifted her head gently. Surely he'd have no problem offering her a bit more, right? She aimed to press their lips together and swirl her tongue around in his mouth. And as she did, she began to shift, from the top of her form first. That ribbon holding her hair exploded and her hair seemed to extend quite a ways down her body. It was black on the outside, but had a strange blue hue within. And when she opened her eyes again, they'd be an eerie glowing teal color. The rest of her body was following along the shift would occur in the downward motion and as it did.... she'd become less human and more demonic.

Were his words direct? He must have been losing his touch, if so. Mugen figured he was giving the usual amount of nearly-misleading information, but it seemed what Kaguya got from it was the answer meant to be less obvious ─ even moving well beyond the clearer step to be taken. Oh well; the results would be interesting nonetheless. Obviously, she wasn't keen on letting the world reject their connection. Mugen was no more accepting of impediment, though he was willing to permit it for the time being.

In a matter of moments, Kaguya's soul began to undergo a change he'd never spectated. That darkness creeping its way into her was accepted in such a way as to be metabolized, not quite making his offering her own, but making herself more like what she received. Ah, she was actually becoming a demon in her own right. Mugen could feel the world's resistance slipping as easily as he saw that hair ornament burst. Miyuki had no idea what sort of demonic possession was happening, but his opinion never mattered anyway. Mugen knew what was happening. He knew the reason for that change in hair and eyes, and he knew how great the transition would be.

More importantly, there was one thing for Miyuki to understand clearly. Kaguya took it upon herself to twist her neck, turning her head to face Mugen. As if it wasn't bad enough to see their lips in contact, Miyuki could see both of their tongues oscillating against each other. He could see the moisture glistening between one tongue and another. Could he... hear it? If nothing else, he thought he could hear it. The view was perhaps the most disturbing thing Miyuki had ever seen, though he still couldn't look away for how absolutely salacious it all was.

Even if he didn't intend for them to be, the more recent words spoken by Mugen held a certain clarity for Kaguya. It was a thing of goodness by her understanding as she had a desire for a certain outcome and would do all that she could within her power to make that happen. That being said, she had every intention of enjoying herself along the way... including but not limited to that rather intense dance of tongues she was currently engaged in.

Whether she fully understood what her body was doing or not, more and more changes were being made to her as this exchange took place. Though her figure didn't change by much her body was certainly shifting to accommodate this new form of existence. In fact, the more it happened the more she was able to accept her body soon seemed to be slackening in resistance which only heightened the pleasure of the experience. Her body was already pressed against this man's back and her loins were already practically dripping. Now that friction and pressure felt more, manageable. Like it would still be quite the squeeze but it would definitely be gratifying once it reached the end of her body. The boy in the floor could obsess and weep if he wished, the spite in her soul said never would he even think he'd be capable of trying to have her. How strange, she didn't think she'd been that angry initially. Ah, but it made this kiss and her descent so much more fulfilling.

One thrust was taking a very long time. Oh, how worthwhile the time spent was. Mugen was pleasantly surprised by how quickly Kaguya sought oneness with him. Of course, he still felt karma in place. Even now, much of what she did was an act of spite against Miyuki. Many would have preferred being a bigger focus, but Mugen was not among that number. He was actually even more elated, if only because her spiteful nature meant she was becoming more like him. Becoming more like him, meant she was becoming even more suitable than she already was ─ which was a feat in itself.

Whatever the case, at least two people in this room were enjoying the back-and-forth of saliva. Actually, the number was three... but that still didn't matter. Mugen noted a lack of difference between the moisture of Kaguya's mouth and loins. She was becoming something great, and she was doing so quickly. As if rewarded by her decision to undergo massive change, Kaguya would be entered more deeply by the demon to whom she offered herself. The world's limitations could only hold them back so much when they were both in agreement. At this point, it seemed to have been bested enough to permit half of a full entry. Once more, Mugen didn't seem to mind. Besides, having Kaguya's mouth to keep him occupied was a suitable distraction while also being a thing that would further enable their... unholy union, so to speak.
