(Negative Emotions) Disgust

"Well, Grimm are attracted to negative emotions, generally. Maybe they respond really strongly to certain negative emotions from girls," said Ruby, lazily placing a finger to her lip in thought. That made sense, right?

"Are you sure?" Yang asked, wearily. Negative emotions were not hard to generate when Grimm were around. If negative emotions were what fueled their lust, they'd be inundated with stories and reports of Grimm getting frisky. Yang wasn't denying Ruby, but she was doubtfully curious.

Once again, however, Blake spoke up again.

"Actually, Ruby's right. I learnt from one of the books at the library a while ago, when I was studying for one of Prof. Port's classes. When Grimm find women who display particular, really concentrated emotions, it can rile them up even more, even making them aroused."

"What particular emotions?" asked Yang.

"Disgust, I bet," answered Ruby.

"Exactly," Blake adds, continuing on, "Fear and panic are obvious emotions for Grimm but disgust is the special one that arouses them. Unfortunately, the hornier the Grimm, the more they want to... you know, to the woman. The more disgusted she gets, the more riled up the Grimm gets. It's a horrible feedback loop."

That was in a book she read in the library, Yang thought, puzzlingly.

"Then how can it be so rare?" Weiss inquired to Blake, who had seemingly become the expert in the topic, all of a sudden, "Surely it would happen all the time, if disgust was all it took."

While Blake hadn't formulated any response, Ruby was idly thinking about what Weiss said, trying to think of logical solution to this problem, which was typically unlike Ruby to do but she didn't give that much thought.

Maybe it wasn't so rare, after all. Maybe it did happen all the time, but few girls ever report it happening. Either that, or women aren't actually disgusted by Grimm very much. Maybe sex with a Grimm isn't so... What am I thinking?

Despite Ruby ceasing her train of thought, she hadn't realized that her mouth had just uttered something?
