A Salford teacher has admitted sexual offences involving two teenage girls.
Christopher Drake, 28, pleaded guilty at Manchester's Minshull Street Crown Court to 18 counts of sexual activity with a child.
He carried out a "complete and gross abuse of his position of trust", the Crown Prosecution Service (CPS) said after the hearing.
Drake, of Ellesmere Road, Monton, is due to be sentenced at the same court on 5 August.
He also admitted one count of sexual activity with a child by a person in a position of trust, one charge of taking indecent photographs of a child and a further four counts of possession of indecent photographs of a child.
The charges relate to two girls who were aged 14 and 15 when the offences began.
Speaking after the hearing, CPS lawyer Justin Hayhoe, said: "Christopher Drake's actions were wholly inexcusable and a complete and gross abuse of his position of trust as a teacher.
"He deliberately preyed on his victims for nothing more than his own sexual gratification.
"Following today's hearing, we hope they can now begin to move forward with their lives and try and put these events behind them."
Two charges of common assault and making a threat to kill should remain on file.
