Encouragement was something Sakura understood, not as it related to sex but in the general sense. When the results of such encouragement made themselves known though... it became quite obvious. He was still moving his hips in a similar way and telling Sakura how he had told her he'd show her real fun and continued to shift around in her loins. Over and over she felt the stimulation of that plus the additive movements of his thumb in her rear which did a great deal for stimulating the young goddess. "Mm~" She found herself enjoying the sensation, shaking her hips quite a bit but feeling it still lacking. As she watched in the mirror though she came to a realization. That lack of direct contact was impeding her senses. Whatever he'd taken out of that foil and slipped on wasn't something she enjoyed. It was blocking her sensation which meant it would likely also block the mana she'd come here to study in the first place. What could be the reason for such a thing existing? She had to figure it out, and what was more, she had to find the right time to have it removed. Perhaps it was worth allowing it to play out and see what happened, at the very least she could see if it was as much of an impediment as she thought it would be.
At the same time, Kaguya and Hiroshi were coming to an agreement. She'd leave herself open for him to learn from, if he felt she had something he needed to know. They were developing quite the interesting dynamic, like two people conducting the same sort of experiments together. Speaking of, her own orgasm spilled over but it appeared that they didn't get to share the information. He got the impressions of the information she wanted to share, but not the full imagery. "Ha...ah...ha... That's... pretty terrible for conversion," she said of the lack of information. "Still, perhaps there is something wrong with my methodology. Wouldn't want to leave any stones unturned, and no worries, I am still enough of a demon that there shouldn't be any complications~" she claimed seeming to have a pretty good understanding of her body's current feeling she was sure she could at least break down anything within her body that she didn't wish to exist, though being human came with a great many extra limitations she wasn't really appreciative of, her body was at least treated a cut above the rest. Mugen would definitely be the one to thank for her current less human physiology. With permission given she waited for the sensation that would send her on a secondary spiral, the filling her of womb, what kind of information would he be giving, she supposed she'd be taking a guess at it.
