Just a few months ago, Jessica Bowring had been released from jail for abusing the same boy.
Bowring was sentenced on Wednesday in Somerset County Superior Court.
She pled guilty to two counts of sexual abuse of a minor, and two counts of violating the conditions of her release.
Bowring was convicted two years ago of sexual assault, and served about nine months in jail.
She was forbidden to have contact with the boy after her release, but a prosecutor says Bowring sent the boy more than four-thousand text messages during a three-month period after she got out of jail.
