A BRISBANE mum who sexted explicit photos of herself to her 14-year-old son's circle of friends will not receive a conviction, after a magistrate found she commited the offences during a "flight from reality".

The 41-year-old woman from Brisbane's southside, who cannot be identified, texted images of herself wearing a pink G-string, squeezing her breasts and a picture of her genitals to the three boys, all aged 14.

She also asked the teenagers, who were friends of her son, to "check out her tan line" in various messages sent between November and February this year.

She pleaded guilty to six counts of using the internet to expose indecent matter to a child under 16 in the Brisbane Magistrates Court on Tuesday.

Crown prosecutor Maryam Yousufzai said the woman was contacted by phone by one of the boys, a friend of her son, via a birthday party invitation.

She said the text message exchange began with the mum sending text messages to three boys, all aged 14 turning 15, and told them one of her fantasies was to "dance naked" and have sex with them.

Ms Yousufzai said the mum sent the boys photos of herself, including pictures of her breasts, which asked them to "check out her tan line" while she was wearing nothing more than a pink G-string.

She said the woman sent another of the boys naked photos of herself and pictures of her "chin-down" wearing a leopard print bikini.

The court heard the more explicit photographs sent to the boys included photos of the woman's genitals.

Ms Yousufzai said one of the texts sent to a boy read: "I wanted to f--- you at (my son's) party, I wanted to rip your pants off …"

Other photos sent to the boys included the woman's bottom and images of her breasts being squeezed together with the text "just for you xx".

Ms Yousufzai said the woman was contacted by a friend of the boys in early February this year, who also requested images of her.

She said the woman called the school and reported the behaviour shortly after, which led to a police investigation.

The court heard two of the boys asked for the contact to cease around the time it was uncovered by police.

It heard the boys had in some instances sent photos of themselves wearing only underwear to the mum.

Barrister Steve Zillman, for the mother, said his client had been diagnosed with a psychotic order, was out of touch with reality at the time and had been looking to "bolster her self-image".

He said the woman was diagnosed with adjustment order, anxiety and depressed mood, suffered a "breakdown" and was continuing to seek treatment as a result.

Mr Zillman said his client was extremely remorseful, had suffered significant distress as a result of the matters, and was of "zero" risk of reoffending.

He said she was otherwise a supportive mum of three who was a mechanical engineer by profession.

"This was not a one-way street in term1 of offending," Mr Zillman said.

"It commenced in an innocuous way but of course escalated … it wasn't intended for the corruption of these various lads …"

He said the boys involved were all turning 15 early this year. He said no complaints had been made by the boys involved and there was no suggestion there had been any sort of "emotional, psychological effect or disturbance" concerning them.

Mr Zillman said the woman was highly regarded in her community, cared for her elderly parents and spent time in her daughter's school to help her overcome a learning difficulty.

"This is a wholly unusual case, Your Honour, one of its kind I trust Your Honour has not heard before,'" he said.

Magistrate Elizabeth Hall said she was persuaded by medical evidence the woman was suffering a psychiatric condition and a "flight from reality".

"Your behaviour arises out of a medical condition, not out of an inclination to harm children," she said.

She sentenced the woman to 200 hours of community service.

A conviction was not recorded.
