Virginia Houston Hinckley, a 26-year-old St. Augustine, Fla. high school teacher, charged with having unlawful sexual activity with a 16-year-old boy, turned herself in on Dec. 9, 2015.
CBS affiliate WKMG reported that the student told police he became "flirty" with Hinckley, his English teacher, days after school began and that he and others commented on how she was pretty and how he "tickled" her.
The student initially asked for Hinckley's phone number, according to the station. She said no, but when he asked again the next day, she gave it to him and told him not to tell anyone, the affidavit said.
The two began exchanging text messages, including nude photos, according to the student.
