Mary-Louisa Andrews, 50, let her husband rape her daughter from the age of 10 and get her pregnant three times.
She can be identified after her daughter waived her legal right to anonymity so she could be named and shamed for her role in the evil crimes.
Andrews was caged for four years for ignoring the campaign of abuse over fears her husband Anoyke Andrews would end their relationship.
Anoyke Andrews first began abusing the girl at the age of 10 and she first fell pregnant at just 12 years old.
She was forced to undergo a number of abortions, after which Andrews continued to rape her in the family home between 2000 and 2007.
He was only caught when his stepdaughter, now 28, found the courage to contact police years later as an adult.
Anoyke Andrews was jailed for 20 years after being found guilty of six counts of rape, two counts of indecent assault and assault by penetration.
The couple’s sentencing had been delayed when the woman defendant suffered a panic attack on the morning she was due to appear via video link before a packed public gallery at Aylesbury Crown Court.
The female Andrews burst into tears today as she appeared via video link to receive her three-year sentence for neglect.
Sentencing, judge Francis Sheridan told her: “The tears you shed are for yourself.
"I do not think any of them are for your daughter. I am not in any way influenced.
"You have not shown any sign of remorse.
“It is time somebody told you to your face - and I will: You were a wicked mother.
"When your daughter complained, her complaints were dismissed.
"You will take that dismissal to the grave. You betrayed your daughter to stand by your husband.
“She has gone through what can only be described as a life of hell.
"There must have been times in her young life where there appeared to be almost no remission from abuse.”
Prosecuting, Angus Robertson
said: “When she was aged 12 years, she found she was pregnant. She had a termination of the pregnancy. She did not want to have that termination.
"Mr Andrews told Mrs Andrews that if the pregnancy wasn’t terminated he would end the relationship and leave her.
“Mrs Andrews always insisted that a young man was responsible and the girl should tell the boy he was the father. Mr Andrews continued to have regular intercourse with the victim after that termination.
“She became pregnant again when she was 13 years old, told her mother the father was Mr Andrews and said they could have her child.
"Both defendants were attempting to have a child of their own. Mrs Andrews considered this, but told her to ‘get rid of it’.”
Addressing Anoyke Andrews, who kept his head bowed throughout, Judge Francis Sheridan said: “You were a thoroughly evil and wicked step-father. Let’s call it exactly what it is. That is the finding of the jury.
“The jury believed your stepdaughter. That is her first step to recovery from a life of hell inflicted by you, with the sex drive of a monster.
“You treated your stepdaughter as an object.
