A Queens jury convicted a teacher for using five elementary students as his “personal sex toys” inside their third and fourth-grade classrooms.

Simon Watts, a former teacher at the Jackie Robinson Elementary school, appeared shocked when the foreperson read “guilty” on all eleven counts for forcing four little girls to inappropriately touch his crotch and molested a boy.

“This wasn’t an anatomy lesson, he wasn’t their science teacher. He did this to get off,” said Assistant District Attorney Alison Andrews during her closing statements on Monday.

Watts, 41, was found guilty after two days of deliberations for charges of abuse, forcible touching and endangering the welfare of a child.

The students were aged 8 and 9-years-old at the time of the encounters.

Some testified that Watts called them to the back of the classroom and forced their hands to rub his penis while he sometimes groped them.

One of the students, who was abused “almost everyday” from December 2007 until June 2009 told the jurors that Watts, “ejaculated onto the floor and used hand sanitizer and a tissue to clean it up.”

Others said he waited until they were alone during the after-school program to whip it out or grab them.

Watts was not removed from the classroom until his last fourth-grade victim told her family on March 9, 2010 — the same day she was forced to touch her teacher’s private parts — who, in turn, called the police.

Watts, 5-foot-10 and 230 pounds, was arrested in April 2010 and later released on $200,000 bail.

Three of the student’s parents have pending civil lawsuits against Watts, the Department of Education and the school’s principal Dr. Antonio K’Tori for negligent supervision.

Watts faces up to seven years in prison for each of the top counts when he is sentenced by Queens Supreme Court Justice Michael Aloise on July 22.

Justice Aloise remanded Watts.
