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.
