This is EMG's classic "Train Give Head" file with an added binaural to make it even more effective. Here's the original description -- The listener will experience giving head to a well endowed guy, the detail of the feel and taste right up to giving deep throat and swallowing his cum so realistically that it feels totally real to them even if they have never really done it, and they love every minute of it and be taught that they wish to do this in real life.
