Konoka actually thought of just saying 'sure'. What was the harm?

But then she remembered this was a girl who was both a military genius and unbelievably turned on by this situation, and it might actually fit to indulge this one a little more.

So instead what left her mouth was, "Your mistress will allow it." Sure, it wasn't said with all that much stern authority, but Konoka was a diplomat. She wasn't the callous type of domme and couldn't be one to save her life. But showering affection like a vice? Yeah she can do that. And to that end, she encouraged her by using her free hand to pull her closer.
