Two high school teachers in Orange County, CA were arrested this week after they allegedly threw an alcohol-fueled overnight sex-on-the-beach party for a group of male students.

It's not clear how old the students were—the Orange County Sheriff's Department reportedly declined to comment on the victims or explain how the two teachers, Melody Lippert, 38, and Michelle Ghirelli, 30, first came under suspicion.

The allegations, via the Los Angeles Times:

South Hills High School teacher Melody Lippert allegedly met a group of male students in November at the beach, where she gave them alcohol and "engaged in a sexual relationship with one of them," according to the Orange County Sheriff's Department.

A few weeks later, Lippert allegedly set up an overnight camping trip to the same beach with some students along with Michelle Ghirelli, who had taught at South Hills before being assigned to work in the school district's offices. The two women are suspected of having sexual relations with the students during that trip, which was not sponsored by the school.

Creepily enough, Lippert and Ghirelli weren't even the first teachers at South Hills arrested this week—that dubious honor went to a part-time girls' wrestling coach, who was arrested Tuesday on charges of inappropriate contact with a minor.
