A smoking hot 25 year old Lewisville teacher is accused of having sex with one of her students who is 18 years old.
It's not a crime because of his age (the legal age of consent is 17 in Texas), but it is a crime because of this statute prohibiting sexual contact between a student and teacher.
This teacher, by the way, sounds like she has a lot going for her. Here is her bio. (And this is her myspace page which is set to "private".)
