"What kind of f***ing perverted person are you?" Those are the words of an outraged father, lashing out at teacher Brittany Zamora, who's accused of having sex with his 13-year-old son.

Zamora, 28, allegedly had sex with the teen, who is not being identified, four times, including once in her classroom in Goodyear, Arizona, while another student watched, the Arizona Republic reported.

Zamora allegedly called his parents in an attempt to convince them not to notify authorities.
