used to play this game with a ML, it only works if the partner is someone who loves to be eaten down there. one day, when i was licking her down there, the radio played a song that she liked she started singing along to it.
i then challenged her to continue singing while i licked. i tell you, i have never heard such erotic singing and she was trying really hard to hold a tune.
beats any moan
i guess it wouldn;t work on ladies who dun react much to oral service
