Dedication is not one of Stephen King's better short stories, and may in fact be the worse. It's the tale of a black maid who cleans the room a famous, but personally loathsome writer frequently rents. The writer has the habit of compulsively masturbating in the bed, leaving the stained sheets for the maid to clean up since he's apparently too precious to use a gym sock like a gentleman.
The maid, who is pregnant, randomly decides one day that instead of just throwing away the cool and drying spooge, she'll start licking it up instead. In the book, this is apparently some kind of bizarre, magical compulsion she has that will somehow enhance her unborn son with manonaise from the rich, talented, and successful.
Believe it or not, there is a really strange element of science involved with this. Dr. Gustaaf Dekker of the University of Adelaide found in a study that a woman who regularly ingests semen during oral sex finds herself at a significantly reduced risk of miscarriage. The theory is that getting the female body used to exposure to male genetic material makes it less likely that her immune system will attack a fetus baring those traits.
Keep in mind, this only works with the father of the child, so lapping up jungle juice off of a fart-smelling hotel sheet won't really do any good preventing miscarriage, and under no circumstances does swallowing a load give a baby talents or skills. Otherwise groupies would have birthed an army of Hendrixes and Claptons by now. On the other hand, it might explain the elevated level of douchebags in the world.
