The book It has spanking (or at least abuse) as part of the plot (for Beverly). I believe a few of the kids in The Body (filmed as Stand By Me) were worried about getting spanked as they went looking for the body. The Shining also had corporal punishment and I'm sure that Carrie's mom smacked her.
The problem with King is that he doesn't see spanking as sexy. As a result while he includes corporal punishment it is always tinged with abuse - because he seems to see it as abuse.
Well, the intended "corporal punishment" in THE SHINING had resulted in Jack Torrance breaking his young son's arm in a fit of rage, although the guy later claimed that he'd merely been trying to spank the boy.
AFAIK there's no legitimate spanking, either punitive or erotic, in Stephen King's work--although admittedly I haven't kept up with most of his recent writing...
