A TEACHER at a leading Melbourne high school has reportedly quit her job after posting raunchy pictures of herself and making explicit sexual references on a public Twitter account.

The teacher at Glen Waverley Secondary College posted a number of ''selfies'' on the Twitter account, which had more than 1000 followers. The account was deleted on Friday afternoon.

It is believed the school principal, Gerard Schiller, became aware of the account last week. It is not known if any of the school's 1900 students had accessed the tweets. The account was created at least five months ago.

The teacher used a pseudonym online and never named the school. She posted pictures showing her face, talked about working as a high school teacher and made references to the Glen Waverley area. She was still tweeting to her followers last Thursday, telling them that she ''left work early to come home and masturbate''.

On November 20, she posted: ''The most soothing thought that gets me to sleep at night is being f---ed hard.'' An hour later, she tweeted about a year-8 French class she was teaching.
