Maxon previously was convicted in 1991 of attempted gross sexual imposition and in 2017 of misdemeanor sexual imposition.
Maxon withheld comment before sentencing. Prosecutors said they would recommend concurrent sentences but otherwise remain silent.
Judge Jeannine Pratt said Maxon went beyond sexual touching of the girls.
“He brought them to his household, took advantage of them and violated them,” she said. “The defendant’s actions are predatory in nature … The court needs to protect minors and young women.”
Pratt sentenced him to three years on each charge and ordered him to serve the sentences consecutively after noting that one of the victims had previously been victimized by Maxon.
He previously was a Tier I sexual offender but the designation was elevated to a Tier II sex offender at sentencing. The Tier II designation requires him to register his address with his local sheriff every six months for 25 years.
