Captured Sakura
Sakura let out another yelp of pain as her captor responded to her defiant statement by biting into her neck, this time actively drawing blood from her helpless captive, her hyper-sensitive body ensuring that she felt much pain from the simple bite. Then, as small drops of blood flowed from the small, slowly-healing wounds, the girl pulled away, facing towards her captive in order to give her another lecture on the futility of defiance. Not even bothering to deny her intentions towards the prisoner, she instead began to talk about the certainty of torture if she did not submit, before slapping the girl lightly on the face twice, the pain disproportionate to the level of the impact once more.
However, despite the clear threat in her words, Sakura was not convinced. Yes, it was true that her captor would most certainly torture her if she did not submit, but it was likely also true that she would be tortured even if she did, her refusal to deny that only convincing her even more that it was true. And, whilst she could not avoid the pain, she could at least avoid the humiliation and degredation that would come from submitting to the girl's every whim. Eventually, she knew she would have no choice but to submit, when the pain and frustration became too much but, until that point, there was simply no benefit to doing so. Sakura knew that, if she submitted, the sadistic woman would simply make other, more humiliating demands of her and, even if she obeyed every demand, no matter how degrading, Sakura knew that the woman would find some excuse for making her captive suffer unbearable pain for her own sadistic pleasure.
Yet, despite her defiance, the pain and frustration would not simply vanish. Not even waiting for a response, her tormentor moved her mouth from Sakura's neck towards her rock-hard, abused nipples, taking the left one into her mouth and clamping her teeth around it. Sakura let out a hiss of pain as the girl's teeth put pressure on the hyper-sensitive nub, before letting out a loud scream as she bit down, her teeth pushing into the soft flesh around her nipple with just too little force to break through the skin.
This time, her captor did not stop there, instead rolling the nipple along her teeth, causing Sakura to let out moans of pleasure even as her face screwed up in pain from the rough massage the teeth were giving the sensitive nipple. The moans of pleasure were punctuated by more screams of pain as her captor bit down, the level of pain varying randomly in an effort to ensure that she could not become accustomed to the sensations being inflicted upon her. Her pleasured moans gradually became louder, but the sensation, punctuated by pain as it was, was not quite enough to bring her to orgasm and, so, it just left her frustrated once more. Finally, she couldn't take any more and, out of reflex, she called out.
"S-stop! P-please stop!" she said, hoping for a small respite from the pain, even if she had little intention of doing what the woman demanded of her.
