Two California teachers appeared sheepish in court as both pleaded not guilty to having drunken cocaine-fueled sex with their high school students on a beach. Melody Lippert, 38, and Michelle Ghirelli, 30, originally escaped sex charges as prosecutors could not find evidence linking them to one of the five boys implicated in the trip. But on Wednesday, both answered to charges of unlawful sexual intercourse at a Newport Beach court.
