In all seriousness I've noticed that during a dance if a dancer shoves her pussy in my face were I can sniff it and munch on it I get instant wood.
Usually normal dances I get hard middle or near the end of song 2 so once erect if she starts to give attention I buy at about 4 more songs.
But !
I've noticed the bitches that shove that monkey in my face during song one and let me investigation with my nose and tounge my Lil Phil is up like Boom !.
Any others find this or something else seem to work like majic
