does the player or will the player ever have things like fellatio stance and such? and what does arousing them with taunt do?
Arousing them with taunt does just that - arouses them. In the future, it'll both arouse them and make them more aggressive, letting you take advantage by making them tire themselves out... either by blocking or otherwise stonewalling their big attacks, or by engaging in some extracurricular, tiring activities. :D
