Sakura might have been ridiculous by the standards of humans, but it wasn't just them who failed to realize extremeness of her antics. Hiruko for his part as new pet owner was apt to give treats, by her own approximation of the nature of their relationship, it was hers to serve. The human logic of service wasn't the goddess logic of service, those who provided the means to create served, offering their life essence and energy to make something of literal thoughts. But humans didn't understand this, and the ones acting became those who serviced. Odd as that was, it suited her needs while on this mana-less planet to be given mana instead of giving up her own. But in this case, it wasn't about the mana, it was about the sensation. She now fully understood the nature of desire, and simply wanted an experience.
She had that thought as Hiruko's dick slid into her mouth and down her throat. He'd not answered her yet, but it seemed her assumptions were right about the nature of the exchange and why it'd be considered a treat. She looked at him while her throat convulsed around his dick happily responding to the throbs as it rested. Apparently hers was indeed to be considered an odd request as the pet, but, when she asked for things she generally wasn't told no, and Hiruko wouldn't be breaking that pattern. He laughed in what Sakura assumed to be one of those odd bits of sarcasm, but then said she could have what she wanted and suggested she turn around. In removing him from her mouth, another quick kiss was placed at the tip of his cock and a cheeky little wink went with it. "Hai, Hirrun♥~" she chimed happily. And then she turned. As her hands were still bound behind her, she got a very direct view of Kakihara and though he wasn't bad to look at, he wasn't at all her focus. She found herself looking at him even so, studying his face. She'd not directly acknowledged him much this entire time, but from this distance she might get to understand how his brain was working around the fact that she'd just succeeded in getting someone else to agree to a thing he'd been trying to use as a method of capturing her.
