You might be shocked, but liquor was involved.
Two Covina women were arrested Saturday for engaging in sexual encounters on the beach with their high school students, police said.
South Hills High School teacher Melody Lippert, 38, met up with a group of male students from her high school at a beach in San Clemente in November of last year, CBS reports.
Lippert reportedly gave the group alcohol and then engaged in a sexual act with one of the students, according to deputies.
Afterwards, she reportedly made plans to meet up with the students a second time at the same spot, bringing along another teacher 30-year-old Michelle Ghirelli.
The two met up with several of the same group, spending a night on the beach during which they had sex with two students, police said.
