The beautiful art of cock sucking in which one lovingly places the penis of one's partner into one's mouth and caresses it with the tongue and tonsils while at the same time sucking ever so gently and moving one's head back and forth massaging the head of the penis.
If fellatio is performed properly, one's partner will ejaculate, at which time you should swallow his generous deposit, though amateurs often expel the semen from their mouths.
Fellatio should be practiced frequently, for every art and skill should be honored and perfected.
