Lestina Marie Smith, from Michigan, was arraigned on Tuesday on two felony counts of first-degree criminal sexual conduct.
The charges stem from an incident that took place on January 11 in Saginaw Township involving Smith and a 19-year-old.
The alleged victim has not been named due to the sexual nature of the crime, and no additional details about the suspected assault have been released by police.
Smith was ordered held without bond at Saginaw County jail.
She is scheduled to appear in court on February 3 for a probable cause hearing.
If convicted of the felonies, the young girl could be sentenced to life in prison.
