The two suburban Los Angeles high school teachers, who allegedly had an alcohol-fueled sexy beach party with 5 male students, are facing additional charges this week. Melody Lippert, 38, and Michelle Ghirelli, 30, were arrested last month for giving the underage students alcohol; prosecutors now say they had sex with the boys and gave them cocaine.

Both teachers now face felony charges of unlawful sexual intercourse and furnishing a controlled substance to a minor. Ghirelli is also charged with one felony count of oral copulation of a minor, KTLA reports.

Although the details are still a little sketchy, a release from the Orange County District Attorney's office fills in a little bit more of what prosecutors believe happened on that camping trip in December.

According to the DA., Lippert sent a group text to Ghirelli and the five boys, inviting them camping for the weekend. On the trip, the two teachers allegedly gave the kids booze and coke, and Lippert allegedly "facilitated Ghirelli's sexual relationship" with an unnamed 17-year-old.

Ghirelli—who formerly taught with Lippert at South Hills High School in West Covina, worked for the Covina-Valley Unified School District at the time of the trip—is accused of having sex with the teenager and giving him a blowjob.

Investigators said Lippert had also taken a group of male students to the beach back in November, where she gave them alcohol and had sex with one of them. That student was believed to be 18 at the time.

South Hills High School has had a rough 2015 so far. The week before Lippert and Ghirelli were arrested, "a part-time girls' wrestling coach was arrested for allegedly having inappropriate contact with a 17-year-old student," NBC Los Angeles reported.
