An Adelaide Catholic college teacher would sneak into her student's home for sex and supply him with alcohol and drugs, it's been alleged.
Sonia Mackay is facing a South Australian District Court, where on Wednesday she pleaded guilty to persistent sexual exploitation of a 17-year-old boy, reports 7 News.
Mackay, a 42-year-old former Christian Brothers College teacher, had an intimate relationship for months last year with the then 17-year-old student and gave him a key to her house, according to a court prosecutor.

In a victim impact statement, the student's mother said the teacher had called her asking for his phone number so she could help him with school work.
The relationship got so serious that the boy would disappear for days at a time.
"I had no idea where he was sleeping, who he was with, was he safe or worse," she said.
"When he attempted to come home, she bought him expensive underwear and gifts so he had no excuse but to stay with her."
On one occasion, Mackay threatened self-harm if he didn't see her.
Mackay also read out a letter, saying she was "ashamed" and "deeply sorry" for her "gross breach of trust".
"I'm a good person who made a really big mistake," she's reportedly told the family.
The teacher was arrested last year and appeared in court in September where she pleaded not guilty to two aggravated counts of indecent assault, and one count of unlawful sexual intercourse which involved another boy, reports the Adelaide Advertiser.
Under the state's law, the age of sexual consent is 17, but it becomes 18 if one of the parties holds a position of authority over the other.
Mackay is expected to be sentenced next month.
