Milking Kimberly - Esmeralda Greene Before reading this I'd heard of infantilism -a mostly non-sexual fetish, role-playing as adult babies, that may involve breastfeeding, via a certain episode of CSI but I'd never heard of erotic lactation fantasy before. After a few Google clicks it seems it's a common thing ("erotic lactation" brings up over 2 million hits) not much talked about because it's taboo. Curiosity satisfied.
