A blow job feels forced, obligatory. Cock worship is eagerly voluntary.
A blow job is (sometimes) done with reciprocation in mind. Cock worship is completely non-reciprocal; nothing is expected in return.
Both a blow job and cock worship brings pleasure, however, to me, cock worship brings a much deeper level of satisfaction for both parties involved.
A blow job can leave me feeling empty, unfulfilled. Cock worship leaves me happy, complete, fulfilled.
A blow job gets the other person off. Cock worship gets me off. (well, okay, he gets off too!)
A blow job can be quick and meaningless. Cock worship takes time and devotion.
A blow job involves sucking the cock to orgasm. Cock worship encompasses all the senses: The feel of the cock as it hardens, the balls as they stiffen, the soft skin, the erotic crevices, your hands exploring his body, the fist in your hair. The smell of his skin, that certain scent he emits. The look on his face, watching him watch you, seeing his pleasure, watching him respond to your touch, your breath, your tongue. The taste of him, his uniqueness, the pre-cum. The sounds he makes as you drive him wild; the sucking, licking, slurping sounds your mouth makes; the point of orgasm.
A blow job involves the mouth. Cock worship involves the mind.
A “good girl” gives a blow job. A “bad girl” worships cock. (and, YES, us girls can be both!)
A blow job says “I love cock!” Cock worship says “I love your cock!”
A blow job says “I love sex!” Cock worship says “I love you!”
