A creative writing teacher sent "sexually charged" and suggestive messages to a pupil after they read 50 Shades of Grey together, a court heard.
When discovered, Thomas Stirling, 24, attempted to cover up the string of explicit messages by claiming he had been comparing the erotic novel's "grammar and content" with the dialogue in Shakespeare's tragedy Macbeth.
However, the true nature of Stirling's messages were later laid bare when his girlfriend uncovered a number of "compromising" photos on his mobile phone, which he had exchanged with a 17-year-old pupil.
After uncovering additional messages sent between the pair on the social media website Instagram, his girlfriend swiftly broke off the relationship and alerted the education authorities in her hometown of Sheffield.
Stirling, whose contract at Franklin College, Grimsby, was later terminated, was also found to have made references to the 17-year-old pupil's virginity and a number of sexual acts which were described in court as having "an element of fantasy" about them.
