Now they have mp3 to play the AUDIO AD from MM (or dubbed voice) to convey Sexy words of MM.
Now if one can play it back later before the session, one can verify if the voice is indeed the MM's.
Anyway it may prove to be worth nothing for you to walk.
Of course voice is not the same as Video, may be that will be the NEXT STEP coming instead of all these fake pic shown on the sites. Some sexy speech may make you horny too instead of just written words to promote a MM.
