A Warman woman who had sex with three of her son's 14-year-old friends will now spend three years in a federal women's prison.

The Saskatchewan Court of Appeal increased Kelly Minogue's sentence, which was originally two years, in written decision earlier this week.
 
The 39-year-old divorced mother was sentenced in June after pleading guilty to three counts of sexual interference stemming from 2010.

Crown Prosecutor Sheryl Fillo appealed the sentence, arguing it wasn't consistent with similar rulings.
 
"Because there was a series of major sexual assaults that took place over a four month period. The sentence of two years was not reasonable," said Fillo.
 
Justice Georgina Jackson agreed Minogue couldn't have had a "momentary lapse in judgment," noting how she hosted the drinking parties where the assaults happened, bought the teens alcohol and had sex with one of them on three separate occasions.
 
"I have spoken to one of the parents since the decision came down. They were extremely pleased and relieved at the result," said Fillo, who actually recommended a three and a half year sentence.
 
However, Jackson ruled three years in a federal prison is appropriate. In her decision, she mentioned how Minogue has been punished in other ways, including the complete loss of a relationship with her children.
 
Jackson also believes the sentence will "fall more harshly" on her compared to other offenders serving similar sentences.

Minogue is currently in an Edmonton prison receiving sex offender treatment for women, therefore isolated from her parents which Jackson described as her "primary source of support."
