Coral Lytle has admitted to having sex with her daughter's school friends - including a 14-year-old boy.
The abuser from Visalia in California faces at least four years in prison after pleading guilty to 221 felony offences, Visalia Times Delta reports.
Lytle now faces charges of sexual intercourse with a minor, oral copulation with a minor and showing porn to a child.
The 42-year-old has been molesting one of her victims since 2017 when he was 15. Shortly after, she did more sexual acts with another boy.
