27-year-old Eppie Sprung Dawson lost her job and her marriage after being discovered half-naked with teenager Matthew Robinson.
She narrowly escaped a prison sentence and is now working as a bartender
But she has moved the boy she was caught with into her house, to the distress of his parents who are appealing to him to come home.
Matthew, now 18, left his parents’ house last week after a fight with his mother over failing to tidy his room. He is now living with his former teacher and they fear he may not return.
According to his mother, after the fight, he called Eppie to come and pick him up.
‘We don’t know what she is after and what is in her mind. I think the whole family are still in shock. You send your child to school and you expect them to to be safe.
'She is a sex offender - she has abused her power and her position to gain the trust of a child and to do this. Given he was 17 when this happened, she should have gone to jail.’
The young teacher’s affair was exposed when they were caught together in her car following a school dance last December.
The pair were half-naked when police knocked on the window and she pleaded guilty to sexual activity with a person under 18 while she was in a position of trust and his teacher.
Sprung Dawson escaped being jailed at the court case in July but was ordered to sign the sex offenders’ register for six months.
She lost her job at St Joseph’s College in Dumfries and separated from her husband of two years, Ranald Dawson, also a teacher and the son of former Solicitor General for Scotland Lord Dawson.
The pair have stayed in close contact and she has showered the youngster with expensive Xbox computer games and rugby tops.
