Tiffany Michelle Amos was a substitute teacher in the Spring school district with an apparent hankering for one of her students.
She knew not to have sex with him until he turned 17 -- and indeed, on his 17th birthday she invited him over and had sex with him, court documents say.
Unfortunately for her, the build-up to that moment included her sending nude photographs of herself before the big day, court documents say.
Amos told an investigator "she intentionally and knowingly took nude photographs of herself at her home with her cell phone and intentionally sent the nude photographs to the [boy] before his 17th birthday," court documents say. "[She] was aware of the [boy's] birthday because she had entered the date into her cell phone."
Amos, 25, faces a felony charge of online solicitation of a minor.
