I also prefer realistic pee videos. Especially when anybody has a big urge to pee or is nearly bursting, or leaking and so on, then it´s much more exciting by knowing that the bladder is really full and she/he feels a real pressure and the movements and the talk are real, honest and true.
I agree, I also like to listen the girls talking. I guess it´s necessary to speak very well Russian to understand what they say. So in this case it´s nice to hear English speaking girls talking. Well, German I also understand, because it´s my native language.
