"Married high school teacher Jennifer Vigil, 31, allegedly pounced on her now 18-year-old victim at Pojoaque Valley High School..."

"... 'You're not leaving until I get something from you,' she reportedly threatened him."

He said he refused to have intercourse but agreed to let her perform oral sex so he could leave — taking a cellphone picture of the act which he later handed to police as evidence.

They then had sex some days later after Vigil dismissed a science class.

Vigil — married since July 2009 — told cops the "relationship" was consensual and says the student made the first move. But he claims he found the whole incident "disgusting."
