It also features a student "lazily" flirting with a teacher and compares two youngsters to "gorgeous Mr Gay UK finalists."

The fiction – Stop! Don't Read This! by Calder High's Leonora Rustamova – is riddled with expletives, features pupils skipping school and drinking under age, hints at drug use and says the five main characters are known to police.

The Courier has obtained a copy of the book, withdrawn from a self-publishing website when Miss Rustamova – Miss Rusty – was suspended.

Another teacher Steve Cann (believed to be a union representative) has also been suspended.

The suspensions prompted hundreds of pupils to hold mass demonstrations and create internet pressure groups supporting the pair.

They say the book was only written to encourage students to read.

It features five Year 11 pupils – all real students or ex-students and constantly referred to as Miss Rustamova's "favourites" – who discover a criminal drug den beneath the Mytholmroyd school.

The story names several teachers, including head Stephen Ball, and features pupils missing lessons, stealing phones and setting themselves on fire.

One pupil is described as fantasising and flirting with Miss Rustamova, while she says she would do anything for a smile from another.

She writes: "It's getting harder and harder to see them just as kids."

Later she describes in the novel how the youngsters practise "orgasmic moans", which sound like "the soundtrack to teenage gay porn".

One main character and a sixth student are described as sunbathing shirtless, "looking like gorgeous Mr Gay UK finalists in an area of Britain where there is some pretty stiff competition."

The book ends with the boys being labelled heroes after revealing to police a drugs store beneath the school – although it is noted a case of cocaine goes missing before officers arrive.

"I suppose the boys had earned a hell of a ritzy summer holiday," says the book. Despite its shock content, campaigners say the book has helped pupils to learn.

Chris Ratcliffe, a parent of former pupils, said: "It's a work of fiction, even though some characters are based on real people.

"I don't think there's anything there that would concern parents, unless they're Mary Whitehouse types.

"It's no worse than TV shows like Skins, and just as fictional. I mean, drug dealers under Calder High isn't going to happen."

One named student, who has since left for college, said: "I can understand why parents might not be happy.

"But of the five main characters – me and my friends – all of us and our parents were fine with it. We like it.

"It helped us take school seriously."

The school, Miss Rustamova and the National Union of Teachers refused to comment because an investigation is under way.
