Coral Lytle, who will now have to register as a sex offender for life, wept as she was taken into custody in a Tulare, California courtroom.
Family members of the victims, who were 14- and 15-year-old high school freshmen at the time of the crimes, lashed out at Lytle.
"Your name will always be equated with being a sex offender and rapist, because that is what now defines you," said one of the mothers of the victims in a statement obtained by the Fresno Bee.
The crimes occurred in the fall of 2017. The victims were said to be boyfriends of Lytle's daughters.
"Coral Lytle is a predator, and this office was prepared for years to tell that to a jury. While I am grateful that she will serve prison time and have to register as a sex offender, the sentence doesn't reflect the lifetime impact she made on her victims," District Attorney Tim Ward told KSEE.
Lytle, a mother of four, plead no contest in October to 21 felony sex counts with the boys, according to KFSN.
