He is the vilest pervert teacher New York has ever seen.
A sex-crazed Brooklyn educator had intercourse with several female students, took them to sex clubs and nude beaches and handed out straight A’s to a girl he was sleeping with, prosecutors said Tuesday.
The debauchery of Sean Shaynak, 44, came to light after the math and physics teacher at Brooklyn Technical High School was charged in August with sending a picture of his private parts to a 16-year-old student.
But that was only the beginning of the lurid misdeeds prosecutors accuse the divorced father of a 9-year-old daughter of carrying out.
