Lynne Freeman, 38, was turned into police by a 14-year-old boy who said she took him into a closet and sexually assaulted him.
After Freeman was arrested in June, a 16-year-old boy came forward with similar allegations.
According to court documents, Freeman's daughter caught her performing a sex act on the 16-year-old.
When Freeman is sentenced next month, she faces between one and 10 years in jail and a fine of up to $2,500 or both.
