Helen Goddard has been given a 15-month sentence after she confessed six counts of sexual activity with a child.
The 26-year-old, however, was not banned from contacting the student, who was a virgin and had insisted on initiating the affair.
Social workers eventually stepped in after the school received an anonymous email tip-off.
Cops found several sex toys including vibrators and 'fluffy handcuffs' after raiding the teacher's maisonette in Greenwich, London.
The girl's parents accused Goddard of 'completely breaching the trust in the teacher-pupil relationship'.
"Our daughter has been led to believe their conduct is within the bounds of a normal relationship. We do not believe Ms Goddard fully understood the seriousness of what has occurred," the Sun quoted them as saying.
However, the two still claim to be 'in love' and intend to live together once Goddard is set free.
