Yes...I know there's a reaction called female ejaculation. I just happen to believe this is not an example of it. I will admit, however, to never having been with a squirter? My impression is that it's not quite this "violent" or voluminous an event. I've been wrong before though.
Cytherea is quite unique, that's a given, just as all men aren't Peter North-esque in their ejaculations. My "squirter" did not have such force, but she produced this much and more when she came.
