Ryu was absolutely relentless. Eska couldn't think straight, and her body didn't seem to be in her control at all. It was like her soul was being pulled out from her body, and only through the most embarrassing places at that.
However, she could also feel Ryu's emotion. He was handling it differently than he usually would, but she could tell that something was off.
Truth be told, this wasn't because of Wobbling Fairy. She, much like Ryu, didn't care very much about this woman at all. Although she only really knew a part of the story, she could tell what was happening.
Wobbling Fairy wanted to use Ryu much like Ryu wanted to use her. There wasn't any obligation between either party to make the other feel comfortable.
