Fresh revelations continue to trickle out about the female teacher and female staffer at South Hills High School in West Covina, Calif. who were arrested in January for allegedly enjoying sex romps on the beach with male students during an overnight camping trip.

In addition to plenty of alcohol, the two school employees also allegedly provided cocaine to the students, Los Angeles television station KTLA reports.

The school employees in deep and growing trouble are Melody Lippert, a 38-year-old English teacher, and Michelle Ghirelli, a 30-year-old school district employee.

There were two camping trips. They occurred at San Clemente State Beach — about an hour south of West Covina on Orange County’s stunning Pacific Coast.

Lippert appears to be the ring leader in the sex frolics. Back in November 2014, investigators say, she gave alcohol to a group of male high school students at San Clemente State Beach. (RELATED: Female Teacher, Staffer Victimize Male Students With Traumatic SEX ON THE BEACH)

The second trip to the same beach occurred in late December. Ghirelli was in attendance. This second trip was the alleged cocaine-fueled expedition.

Many of the same students were involved in both trips.

Police say the student with whom Lippert allegedly had sex is 18 years old.

The student with whom Ghirelli allegedly had sex was 17 at the time.

According to the district attorney, Lippert facilitated the rendezvous between Ghirelli and the underage student. There was sex and oral copulation, investigators say.

School district officials have stressed that neither camping excursion was school-sponsored.

“We’re taking the matter very, very seriously,” Covina-Valley Unified School District spokeswoman Michelle Van Der Linden added, according to the Los Angeles Times.

Charges have been upgrades against the allegedly licentious teachers.

Lippert, a 15-year veteran teacher with the West Covina school district, now faces a felony count of unlawful sexual intercourse and another felony count of furnishing a controlled substance to a minor charge in addition to the original charges of conspiracy and contributing to the delinquency of a minor.

Ghirelli, a school district employee for five years, faces a felony count of furnishing a controlled substance to a minor in addition to the original counts of unlawful sexual intercourse and oral copulation of a minor.

Enhanced sentencing guidelines apply because the teachers are at least four years older than the students. Specifically, Lippert is 20 years older than the student with whom she allegedly had sex. Ghirelli is 13 years older than her alleged campsite lover.

Lippert faces up to almost 11 years in prison. Ghirelli faces up to nearly 12 years behind bars.

In late January, a third teacher in the district, art teacher Sean Patrick Kane, was placed on paid leave after he published a Facebook rant opining that the male students erred because they “squealed” about their sexual exploits.

What “is in the heads of the dudes” who had sex with “these ladies and then squealed?” Kane asked incredulously in the Facebook post.

“You should have just kept your stupid mouths shut and enjoyed it,” he counseled sternly.
