Shirou and Sakura
Shirou frowned at her words. It wasn't quite the level of "force" he had wanted her to exert, the logical response would be for him to refuse and help Sakura escape. But, he wanted to do this, desperately, more than anything else in the world. So, regardless of the facts, he took her threat as a valid one, simply because he wanted it to be.
"Oh, I see...", he said in mock sadness. "I guess I'd better obey you, at least for now...."
With that, he walked out of the room, heading for where Sakura was located. Storming in, he grabbed hold of her arm and dragged her to her feet without even giving her the opportunity to come willingly.
"Sakura, you'll have to come with me", he said abruptly, beginning to drag her out of the room.
"Senpai?" Sakura said, questioningly.
No, I don't want him involved in this. He doesn't have to do this for me, she thought, desperately denying her fantasy.
"I just talked a woman who claims your actions in the Grail War hurt her deeply. She wants to punish you severely in revenge, and she is forcing me to assist her in doing so", he said, continuing to drag her to the door.
With that, Sakura stopped resisting. She didn't want to force this on Shirou, but if the woman had decreed that that would be part of it and he had accepted, then she would not question it. And, the very thought of it aroused her immensely. Being tortured by a random stranger was nothing more than a punishment but, for Sakura, anything could be fun as long as it was done with Shirou.
No, this is a punishment, she reminded herself. I should not enjoy it or attempt to enjoy it.
Nevertheless, Shirou dragged her into the room, her arousal began to grow. At the same time, his arousal was also growing. Just the thought of what he might do to her was already making him hard.
As soon as they entered the room, Emily beckoned for them to follow her. Shirou did so, dragging his unresisting captive along with him. After a few moments, they arrived at another room, one which was clearly far more suited for what Sakura had requested be done to her. Roughly pushing Sakura into the room and then following behind her before closing and bolting the door, Shirou looked around, the sight meeting with his strong approval and increasing his arousal even further.
Sakura, meanwhile, was far more ambivalent about the situation. The thought of Shirou violating her was a turn-on but, at the same time, the sight of all the items of torture frightened her. She knew that they would soon be used to inflict much pain and suffering on her helpless body, far beyond anything she could expect to enjoy.
Just like I deserve, she thought.
Meanwhile, Emily was looking around, checking out the room. Quickly, she came to the conclusion that it was ideal for her task, and expressed that thought.
"Indeed, it should be perfect", she said, making her way over to a pillory. "Shirou, be good assistant and lock Sakura into the pillory."
"Yes, mistress", Shirou practically hissed, making every effort to show displeasure that he wasn't truly feeling, and to act like he was not doing this of his own free will.
Nevertheless, he obeyed the order, dragging Sakura over towards the device. Having realised what was about to happen, Sakura began to have some doubts, and started to beg.
"No! Senpai, please, stop!" she shouted.
But, it was to no avail. She had given him explicit instructions to tell her torturer to ignore any begging or pleading and, besides, he was too heavily under the influence of Emily's contract to care. Instead, he simply pushed her down into the device, locking her arms and head in place.
