A court has been urged to jail a primary school teacher for child sex abuse material posted an internet chat site.
Adelaide police seized computer equipment last February from the home of Grant Geoffrey Martin, 45, and found more than 3,000 chat logs from an online child sex-slave forum, including some written under the pretence of being a teenage girl.
Martin pleaded guilty to two charges of producing child pornography, one of them aggravated.
The District Court previously heard he played the role of a victim on the chat sites as an escape from real-life issues.
Prosecutor Rosie Thewlis said Martin was entitled to credit for his guilty plea, but should be jailed because his behaviour encouraged the sexual abuse of children.
"He engaged in several fantasies with other users and conversations involved him assuming the identity of a female aged between 13 to 16 years.
"The main theme of the conversations involved the female being a submissive slave to her male master."
Ms Thewlis said there had been chat about being "tied up and gagged, whipped, slapped, raped ... and being used as a sex toy and prostitute".
"He participated in the production of child exploitation material for at least eight months and on at least 68 occasions," she said.
