It was definitely the overwhelmed status of her mind which contributed to her hysteria about the extra arms. Of course, she'd been calm when assessing his extra eyes, but this was an oddity of her person. The extra eyes made her figure he had a rather interesting skull. But that wouldn't matter much at all to her in the future. In a moment those extra arms swelled in size becoming swelled with intense mana. Given his own proclivities, that had to be an extra use of curses. Buffing, healing, harming... it seemed pretty flexible as a type of magic. But now she was being lifted, and squealed in a most frightened way as it happened. Her hair was still being pulled, that tongue had began to explore deeper reachers of her rear, causing her to squirm instinctively as it felt rather... pleasant. No. It shouldn't right? She didn't know. If making someone panic was a personal skill, Sukuna definitely possessed it when it came to Kur. Now her body was aligned with his massiveness and he had but one amused thing to say regarding why he had four arms. And it was once again spoken in his mother tongue. Was he doing that just to panic her? It wasn't magically induced nor actively cursing it, but it was causing a bit of slowness in her replies. She had to process his words a bit, while having her body stimulated, ven was you... er was a preposition like of, no she knew that one. It was more like to... and transitive... The middle word was large and ominous and rounded on the ends. Destroy. He had four arms, to destroy her? Oh no!! Was he going to pull her apart? Was he going to rip her limp from limb and only use her torso? Was it more figurative instead? She didn't know but all options were more than a bit frightening. Should she resign herself to fate and hope she didn't end up maimed for resisting, even as it was the natural instinct of her form?
At the same time, the crying Kur and the monstrous man taking advantage of her seemed to please Ishtar. That enhancement of his form seemed to garner appreciation, though not the extra appendages at all. She found non-human torsos unappealing in the most uncharacteristic way. All those extra mouths and tongues and eyes were also pretty off-putting but he didn't need to be that way all the time, just when he was entering her glorious form. Besides he kept cursing that girl, she wouldn't be surprised if she eventually faltered just because her body could no longer take the torture. "Finally accepted it? Crying won't save you... and pleading won't either... do you get it now, Kur. You shouldn't have ever stood in front of me! Ohohohohoho!~" that shrill laughter echoed, but Kur could barely process it.
All of those sounds that Ishtar took for pain, weren't at all physical pain. Kur was over stimulated. Her loins dripping and throbbing and the panic of the moment was her confusion around the way she was feeling versus the definition of the thing happening to her was causing her to panic every time she experienced something akin to pleasure or shock. Here and now, that oscilating tongue on the way out of her rear made her squirm a bit, and the sound that escaped her mouth first was a bit more moan than panicked yelp. She'd told him, that she didn't want to be vile and gross inside and out like Ishtar, and he'd said something else in his own language. At the same time her body seemed to be metabolizing that first couple of doses of mana. Having been circulating for quite a while she felt a pain in her chest and a gentle soreness of her thighs, chest and back, she was expanding, filling even. he didn't take enough of that mana back for her body not to keep it. And then he said... Be... corrupt? That was weird. Why would she be corrupt. Oh... the rest of that sentence was another of his asking a question. She could choose in this instance how she was violated or he'd do it for her? Did she really understand that right. "I.. I..." there was a moment of hesitation. She didn't want to be gross inside and out, but she also didn't want to always hate everything about the sorts of activities that were forced upon her now. If she took it into her own hands... she could at least take responsibility for the choice. It would decrease the amount of victimhood she had to live with... Besides, she didn't want him forcing himself into her, nor using cursed speech to force her to do it a specific way, when she didn't know what it would feel like. She'd take it slow... She was already aligned and though he'd been tonguing her rear, she decided the other hole which was actually made for such things would be less potentially painful. So she went about moving her hips in such a way, as to lower herself onto his girth. She'd accept it, and though the fit would be intensely snug, she would start copulation of her own accord. All the while Ishtar laughed. "He cursed you and made you do it yourself... oh how the puny become pitiful!"
